Thu Jul  3 20:36:19 1997  Nanbor Wang  <nw1@cumbia.cs.wustl.edu>

        * performance-tests/Misc/childbirth_time.cpp: Changed the
          parameter type of "Profiler" from int to size_t to make g++
          happy.

Thu Jul 03 20:03:18 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Reactor.cpp (remove_handler): added ACE_UNUSED_ARG
          when NSIG != 0.

Wed Jul  2 23:41:43 1997  Nanbor Wang  <nw1@cumbia.cs.wustl.edu>

        * performance-tests/Misc/childbirth_time.cpp: Fixed some typos.

Wed Jul  2 23:13:10 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * performance-tests/Misc/childbirth_time.cpp: Revised the
          code to use ACE programming style.

Wed Jul 02 23:02:24 1997  Douglas C. Schmidt  <schmidt@cs.wustl.edu>

        * ACE version 4.2.15, released Wed Jul 02 23:02:24 1997.

Wed Jul  2 22:23:49 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Service_Config.cpp: Used the new ACE_LACKS_UNIX_SIGNALS
          macro to reduce the #ifdef complexity somewhat.

        * ace/config-{chorus,win32-common}.h: Added #define for
          ACE_LACKS_UNIX_SIGNALS.

        * ace/OS.h: If a platform (e.g., Chorus) doesn't support signals
          then #define NSIG 0.

        * ace/Reactor.cpp: Chorus does not support signals.  Make the call
          to register/remove_handler(sig_set, evnet_handler) return
          succesfully so that some of the examples and test programs do
          not need to be changed.  Thanks to Wei Chiang for this.

        * ace/config-chorus.h: Added a new macro for
          ACE_LACKS_NAMED_POSIX_SEM to handle Chorus.  Thanks to Wei
          Chiang for this.

        * ace/OS.i: Define macros ACE_PTHREAD_CLEANUP_* so that the
          related code does not need to be surrounded with #ifdefs.
          Thanks to Wei Chiang for this.

        * ace/OS.i: Chorus does not support named semaphores. The code
          that to do with names in sema_init() and sema_destory() is
          therefore disabled.  Thanks to Wei Chiang for this.

        * ace/config-chorus.h: Added support for ACE_LACKS_PTHREAD_CLEANUP
          and ACE_HAS_POSIX_SEM to the Chorus port.  Thanks to Wei Chiang
          for this.

Wed Jul  2 17:37:09 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Hash_Map_Manager.cpp: Clarified the behavior of close_i() a
          bit more.

Wed Jul  2 09:54:36 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Hash_Map_Manager.cpp: Fixed a couple more size_t->u_long
          conversions for ACE_Hash_Map_Manager::hash().  This didn't harm
          anything but it's good to be consistent.

Wed Jul  2 16:46:59 1997  Nanbor Wang  <nw1@cumbia.cs.wustl.edu>

        * performance-tests/Misc/childbirth_time.cpp: Added this program
          to measure child process/thread creation mechanisms on various
          platforms.  Native thread creation test only supports Solaris
          and NT threads so far. But you can still use ACE_OS::thr_create
          method on your platform if not supported.

Wed Jul  2 15:59:53 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * ace/High_Res_Timer.cpp: Created a function get_registry_scale_factor
          that finds out the speed of the processor using the NT registry (in
          megahertz).  This means that ACE_High_Res_Timers should automatically 
          get the correct scale factor.

        * tests/Timer_Queue_Test.cpp: Removed the call to 
          get_env_global_scale_factor().

Wed Jul  2 15:39:33 1997  Tim H. Harrison  <harrison@waltz.cs.wustl.edu>

        * ace/Process.cpp: Modified spawn to check for the NO_EXEC
          flag after forking on UNIX.  If it's set, spawn returns the
          child pid without exec'ing.  Updated the NT version to
          always return the child pid on success.

Wed Jul 02 10:55:23 1997  David L. Levine  <levine@cs.wustl.edu>

        * tests/SPIPE_Test.cpp,UPIPE_SAP_Test.cpp: tweaked the static
          functions a bit to avoid warnings about unused statics on VxWorks.

Wed Jul 02 00:16:07 1997  Douglas C. Schmidt  <schmidt@cs.wustl.edu>

        * ACE version 4.2.14, released Wed Jul 02 00:16:07 1997.

Tue Jul  1 22:49:58 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Strategies_T.h: Changed the return value of all the hash()
          methods to be u_long.

        * tests/Map_Manager_Test.cpp (hash): Changed the return value of
          all the hash() methods to be u_long.

        * ace/SString.cpp: Changed the return value of all the hash()
          methods to be u_long.

        * ace/Hash_Map_Manager: Changed the return value of hash()
          to return a u_long in order to (1) be consistent with
          the return value of hash_pjw() and (2) give the maximal
          range for the hash function.  Thanks to Marina Spivak
          <marina@cs.wustl.edu> for reporting this.

Tue Jul 01 14:47:22 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/High_Res_Timer.{h,i} (gettime): use gettime () static function
          to wrap all calls to ACE_OS::gethrtime ().  On ACE_WIN32, if the
          global scale factor has not been set, then gettime () uses
          ACE_OS::gettimeofday () instead of ACE_OS::gethrtime (), because
          gettimeofday doesn't need the scale factor.

Mon Jun 30 17:28:53 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * Makefile (RELEASE_FILES): Removed the rpc++ directory from the
          main release since this doesn't seem to be widely used and the
          GPL copyleft confuses people.

Mon Jun 30 15:08:04 1997  David L. Levine  <levine@cs.wustl.edu>

        * include/makeinclude/platform_vxworks5.x_g++.GNU: added -lgcc
          to LDFLAGS.

Mon Jun 30 12:00:02 1997  Douglas C. Schmidt  <schmidt@cs.wustl.edu>

        * ACE version 4.2.13, released Mon Jun 30 12:00:02 1997.

Sat Jun 28 08:27:27 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: added definitions of ACE_SHLIB_HANDLE and
          ACE_DEFAULT_SHLIB_MODE on platforms other than
          ACE_HAS_SVR4_DYNAMIC_LINKING and hpux.

        * ace/OS.i: split definitions of ACE_OS::cond_* member
          functions into two:  for ACE_WIN32/VXWORKS and all others.
          That allows us to break the circular dependencies between
          those functions and the ACE_OS::sema_* member functions.

        * ace/Svc_Conf_y.cpp: commented out unused args and wrapped
          assignments in "if" conditionals with parenthesis to avoid
          g++ warnings.

        * ace/{ACE,INET_Addr,OS}.cpp (VxWorks only): added ACE_UNUSED_ARG
          calls.

        * ace/Parse_Node.cpp (ACE_Stream_Node,ACE_Dynamic_Node,ACE_Dummy_Node
          constructors): reordered initializers to match declaration order.

        * ace/Profile_Timer.h (elapsed_time): commented out unused arg "et".

        * ace/Read_Buffer.cpp (rec_read): initialized local variable "c" to
          make sure that it is always defined before use.

        * ace/SPIPE_Acceptor.cpp (remove): don't declare local variable
          "result" if ! ACE_HAS_STREAM_PIPES, because it's not used in
          that case.

        * ace/config-vxworks5.x-g++.h: added ACE_LACKS_IOSTREAM_FX,
          ACE_LACKS_LINEBUFFERED_STREAMBUF, and ACE_LACKS_SIGNED_CHAR.

        * ace/IOStream_T.h (ipfx): comment out unused variable "need".

        * platform_vxworks5.2_g++.GNU: added -Wall now that the ACE library
          builds cleanly with it.

        * platform_vxworks5.x_g{++,hs}.GNU: renamed 5.x instead of 5.2.

        * netsvcs/lib/Token_Handler.cpp: reordered initializers to match
          declaration order.

        * tests/SV_Shared_Memory_Test.cpp: moved template specializations
          so that they're not done on platforms that don't support SV IPC.

        * examples/IOStream/client/iostream_client.cpp,
          examples/IOStream/server/iostream_server.cpp:
          use ACE_HAS_STRING_CLASS rather than __GNUC__ to determine whether
          the platform has a String class.

Fri Jun 27 13:10:46 1997  Douglas C. Schmidt  <schmidt@merengue.cs.wustl.edu>

        * ace: Changed the name of config-vxworks5.2-g++.h to
          config-vxworks5.x-g++.h since it works with 5.2 and 5.3.

        * examples/Mem_Map/IO-tests/IO_Test.cpp: Fixed some bugs that were
          preventing this from running correctly.

Fri Jun 27 13:37:37 1997  Steve Huston  <shuston@riverace.com>

        * ace/Svc_Conf.y: Finished the sanity checks started below.

Fri Jun 27 11:55:13 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * ace/Timer_Queue_T.cpp: added a check for an empty queue in expire

Fri Jun 27 07:53:58 1997  David L. Levine  <levine@cs.wustl.edu>

        * tests/Message_Queue_Notifications_Test.cpp (handle_output,
          handle_exception,main): added ACE_UNUSED_ARG (fd) to avoid
          compilation warnings about unused arguments.

Fri Jun 27 01:08:54 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Connector.cpp (create_AST): Replaced the gratuitous #ifdef
          for ACE_WIN32 and EXCEPT_MASK with the new CONNECT_MASK.  This
          is much cleaner!

        * ace/Event_Handler.h: Added a new CONNECT_MASK that defaults to
          READ_MASK | WRITE_MASK (with | EXCEPT_MASK thrown in for Win32).
          Thanks to Irfan for this suggestion.

Thu Jun 26 19:53:11 1997  Nanbor Wang  <nw1@lambada.cs.wustl.edu>

        * ace/OS.i (strtok_r): Added check on a null string so we won't go
          past the end of a string.

        * performance-tests/Misc/context_switch_time.cpp (main): Added
          get_env_gloval_scale_factor() at the very beginning so that high
          resolution timer can return correct time in millisecond.

Thu Jun 26 15:29:55 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * tests/Timer_Queue_Test.cpp: Changed the random scheduling to use
          past times instead of future time.  This should fix some unusual
          behavior of this test.  Thanks to Gonzalo A. Diethelm 
          <gonzo@ing.puc.cl> for reporting this.

Thu Jun 26 12:38:16 1997  Douglas C. Schmidt  <schmidt@cs.wustl.edu>

        * ACE version 4.2.12, released Thu Jun 26 12:38:16 1997.

Thu Jun 26 01:11:10 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Svc_Conf.y: Added some sanity checks to make sure we don't
          segfault when things go wrong during the svc.conf file parsing.
          Thanks to Steve Huston for this suggestion.

Thu Jun 26 08:36:37 1997  David L. Levine  <levine@cs.wustl.edu>

        * Makefile: fix UPTODATE check (for release target) by not
          running it in a sub-shell.  Also, added ACE-lessons.html
          to RELEASE_FILES.

        * performance-tests/Misc/context_switch_time.cpp: use same priority
          values on Win32 platforms as on Solaris, because thread priority
          increases with increasing priority values on both of those platforms.

Thu Jun 26 01:34:46 1997  Nanbor Wang  <nw1@lambada.cs.wustl.edu>

        * performance-tests/Misc/misc.{mak,mdp}: Added makefile for NT.
        
        * ace/{FILE,DEV}.{h,i}: Added the disable(int signum) function to
          prevent NT from disabling a FILE/DEV using socket calls.

Wed Jun 25 12:59:00 1997    <irfan@TWOSTEP>

        * ace/Synch_T.h (ACE_SYNCH_PROCESS_MUTEX and
          ACE_SYNCH_NULL_MUTEX): Added new template typedef to the list. 

        * tests/Message_Queue_Notifications_Test.cpp: New test for
          demonstrating notification qualities of Message_Queue.

        * ace/Strategies.h: Added accessors to these classes to make them
          more usable.

Wed Jun 25 10:47:34 1997  Steve Huston  <shuston@riverace.com>

        * ace/Parse_Node.cpp: Insure that ACE_Object_Node::symbol(void)
          returns 0 if the underlying shared library can't be loaded.

        * ace/OS.h: Added a new type, ACE_SHLIB_HANDLE to allow dynamic
          linking using correct types on all platforms that support it.
          Also added a const ACE_SHLIB_DEFAULT_MODE for the 'mode' argument
          when doing a dlopen-like operation.
          Moved the ACE_OSCALL_* macros to this file from OS.i

        * ace/OS.i: Moved ACE_OSCALL_* macros out of here and into OS.h.
          Added support for dlopen/close/sym/error on HP-UX.  Note - the
          Service_Configurator tests do not run yet on HP - I'm working on
          that.

        * ace/Service_Record.{h, i, cpp}: Use new ACE_SHLIB_HANDLE type for
          dynamic loading operations.

        * ace/Parse_Node.{h, cpp}: Use new ACE_SHLIB_HANDLE where appropriate.

        * ace/Strategies_T.cpp: Use new ACE_SHLIB_HANDLE type.

Wed Jun 25 02:36:05 1997  Nanbor Wang  <nw1@lambada.cs.wustl.edu>

        * ace/OS.i (gmtime_r): Modified the implementation of gmtime_r
          when OS doesn't provide one.  Notice that the implementation
          only simulate the semantic and is not thread-safe. 

        * ace/OS.h: Moved definition of ACE_SHLIB_HANDLE typedef and
          ACE_DEFAULT_SHLIB_MODE global variable for Win32 to where it
          belongs.
          
        * ace/OS.i: Changed the return type of dlopen() when ACE_HAS_UNICODE to
          ACE_SHLIB_HANDLE.
        
        * ace/OS.{h,i}: Moved ACE_OSCALL and ACE_OSCALL_RETURN for WIN32
          from OS.i to OS.h.

Wed Jun 25 01:23:58 1997  Nanbor Wang  <nw1@dingo.wolfpack.cs.wustl.edu>

        * ace/OS.i (strtok_r): Modified the implementation when OS does
          not provide reentrant strtok_r so that our imp. comforms with
          the semantic of strtok_r ().

Wed Jun 25 00:37:56 1997  Douglas C. Schmidt  <schmidt@cs.wustl.edu>

        * ACE version 4.2.11, released Wed Jun 25 00:37:56 1997.

Tue Jun 24 21:30:53 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Svc_Conf_y.cpp: commented out unused args and wrapped
          assignments in "if" conditionals with parenthesis to avoid
          g++ warnings.

Tue Jun 24 18:15:46 1997  Nanbor Wang  <nw1@dingo.wolfpack.cs.wustl.edu>

        * ace/Reactor.cpp (wait_for_multiple_events): Modified the way to
          manipulate timeout value so that we can differentiate when there
          are timeout events to be handle from no timer and we want to
          wait indefinitely.

Tue Jun 24 16:52:22 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: reverted ACE_hrtime_t to unsigned __int64 with VC++.
          This might break something, but we need to know what.

Tue Jun 24 16:38:52 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * Added Visual C++ 5.0 specific workspace (.dsw) and project (.dsp)
          files to both the ace and tests subdirectory.  ACE.DSW in the root
          directory contains all the project files, so a batch build should
          be able to build all the project files.

Tue Jun 24 14:27:47 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * ace/Timer_{Hash,Heap,List,Wheel}_T.cpp: Changed cancel (type..)
          to call cancellation() even if there are no timers to cancel.  
          This causes the correct behavior of calling handle_close () 
          during expire when handle_timeout() returns -1.  Thanks to 
          Hamutal Yanay <hamutal_yanay_at_quantum@mail.icomverse.com> for 
          pointing this out.

        * tests/Timer_Queue_Test.cpp: Updated to correctly test this.

Tue Jun 24 13:02:51 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/SString.h (ACE_SString ctor): changed "allocator" to "alloc".
          Thanks to Brian Mendel <bmendel@mdc.com> for reporting this.

Tue Jun 24 12:58:28 1997  James C Hu  <jxh@lambada.cs.wustl.edu>

        * include/makeinclude/platform_irix6.4*: Shuts up useless warnings
          about multiply defined template instances.

Tue Jun 24 12:50:52 1997  Douglas C. Schmidt  <schmidt@cs.wustl.edu>

        * ACE version 4.2.10, released Tue Jun 24 12:50:52 1997.

Tue Jun 24 00:44:30 1997  Nanbor Wang  <nw1@lambada.cs.wustl.edu>

        * ace/SPIPE.{h,i}: Added the disable(int signum) function to
          prevent NT from disabling an SPIPE using socket calls.

Mon Jun 23 22:14:39 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Svc_Conf*: Changed the name of the YYSTYPE field
          ACE_Static_Node_ to static_node_ to be consistent with the other
          fields.

Mon Jun 23 18:28:55 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/ACE.cpp: added auto_basic_array_ptr specialization.

        * ace/Service_Config.cpp, tests/Future_Test.cpp,
          examples/Threads/future[12].cpp: added auto_basic_ptr
          specializations.

        * include/makeinclude/platform_vxworks5.2_g++.GNU:
          reworked to supported different targets, instead of only PowerPC.

Mon Jun 23 16:06:35 1997  James C. Hu  <jxh@swarm.cs.wustl.edu>

        * ace/OS.i: Moved definition of sema_* methods to follow cond_*
          methods to remove compiler warnings on SGI.

Mon Jun 23 09:42:08 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * tests/Timer_Queue_Test.cpp: added testing for cancellation 
          during expire (when of handle_timeout() in an event handler 
          returning -1).

Mon Jun 23 09:18:39 1997  David L. Levine  <levine@cs.wustl.edu>

        * Makefile: added up-to-date check for "make release" from
          /project/adaptive/ACE_wrappers.  Also, "make release" now
          adds release entry to latest ChangeLog.

        * ace/Makefile: build shared library before static library. 
          This appears to fix a problem with Sun C++ 4.{1,2} possibly 
          related to its template instantiation scheme.  If the
          static library is built first, then .shobj/Reactor.so
          and .shobj/Timer_Hash.so (and possibly others) fail to
          build due to ACE_TimeValue::normalize () "relocations remain
          against allocatable but non-writable sections".
          Thanks to Steve Huston <shuston@riverace.com> and
          Satoshi Ueno <satoshi.ueno@gs.com> for reporting this, and
          to Satoshi for verifying the fix.

        * ace/ACE.cpp (terminate_process): removed used of
          ACE_OSCALL_RETURN macro because its defined in OS.i, and so
          not available if inlining is disabled.

        * ace/Auto_Ptr.{h,i}: made "p_" protected instead of private
          so that it can be accessed with the new class arrangement.
          Also, made the auto_array_ptr operator-> const.

        * ace/Sched_Params.cpp (previous_priority, VxWorks only):
          removed ACE_UNUSED_ARG (policy) because policy is used in
          this function. 

        * netsvcs/lib/TS_Clerk_Handler.cpp (parse_args): wrapped TCHAR
          argument to sizeof in parenthesis.

Mon Jun 23 09:12:04 1997  Nanbor Wang  <nw1@lambada.cs.wustl.edu>

        * ace/Auto_Ptr.i (auto_array_ptr): Fixed a typo.

Mon Jun 23 08:03:46 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * ace/Auto_Ptr.h: changed inheritance of auto_basic_array_ptr in 
          auto_array_ptr to include the template parameter X.

        * ace/IOStream_T.i: removed default parameter in the definition
          of ACE_Streambut_T::recv_n() and ACE_SOCK_Dgram_SC::recv_n()

Mon Jun 23 01:13:15 1997    <irfan@TWOSTEP>

        * ace/OS.cpp (fork_exec): Fixed the usage of ACE_WIDE_STRING.

        * test_registry_iterator.cpp (main): Fixed the usage of
          ACE_WIDE_STRING.

        * netsvcs/lib/TS_Clerk_Handler.cpp (parse_args): Fixed the usage
          of ACE_WIDE_STRING.

        * ace/Auto_Ptr.h: Added support for basic types by seperating the
          auto_ptr classes into two. One that requires the -> operator
          support and the other that does not. The former inherits from
          the latter.

        * ace/{FILE,DEV,SPIPE}_Addr.h: Added support for multibyte and
          wide character addr_to_string and string_to_addr functionality.

        * ace/Connector.cpp && ace/Acceptor.cpp (info): Fixed sizeof bug.

        * examples/Connection/blocking/SPIPE: Added UNICODE support for
          this example.

        * ace/OS.h: Added new macro ACE_MULTIBYTE_STRING.

        * ace/ACE.cpp (terminate_process): Fixed unused args errors.

Sun Jun 22 09:58:36 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * Released version 4.2.9 for testing.

        * ace/Log_Msg.cpp (open): Changed the use of ACE_LOG_MSG-> within
          the open() method to use this-> in order to avoid deadlocks.
          Thanks to Per Andersson for reporting this.

        * ace/ACE.cpp: Changed the use of __SVR4 and __unix to sparc and
          unix to work better with various UNIX environments.  Thanks to
          Michael R. MacFaden <mrm@cisco.com> for these changes.

        * ace/Handle_Set.cpp (count_bits): Added special code to handle
          the case where fdmask is typedef'd as a long rather than an int.
          Thanks to Eric Newton <ecn@smart.net> and James Johnson for
          reporting this.

        * ace/IOStream.h: Changed the name of QuotedString to
          ACE_Quoted_String to be consistent with the ACE naming scheme.
          Thanks to James Johnson for suggesting this.

        * ace/IOStream_T.i: Added this new file to split off the inlined
          code from the header file.

        * ace/ACE.cpp (terminate_process): Remove the
          ACE_UNUSED_ARG(signum) from terminate_process().  Thanks to Wei
          Chiang for reporting this.

Sun Jun 22 17:19:18 1997  David L. Levine  <levine@cs.wustl.edu>

        * examples/Threads/process_manager.cpp (main): replaced call to
          kill with terminate.

Sat Jun 21 10:48:34 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * examples/Reactor/FIFO: Added a new example that illustrates
          how the Reactor and the FIFO wrappers work together.  Thanks
          to Johannes Gutleber <Johannes.Gutleber@cern.ch> for sending
          this.

        * tests/Time_Service_Test.cpp (main): Replaced the kill() call
          with the terminate() call since kill() isn't portable across
          platforms.

        * ace/Process: The kill() method on this class was being used
          incorrectly.  I've created a new method called terminate() that
          terminates the process.

        * ace/Process_Manager: Renamed the kill() method to terminate()
          and updated the implementation to use the new
          ACE::terminate_process() call.

        * ace/ACE: Moved the incorrect Win32 and Chorus implementations of
          ACE_OS::kill() and put them in a new static method called
          ACE::terminate_process().

        * ace/ACE: Changed the name of the is_process_active() to the
          more concise process_active().

        * ace/OS.i: Added an implementation of ACE_OS::kill() for Chorus.
          Note that this doesn't behave as UNIX does -- it kills the
          process id rather than sending a signal!  Thanks to Wei Chiang
          <chiang@tele.nokia.fi> for these fixes.

        * examples/Reactor/Misc/notification.cpp: Added patches to run
          this example under Chorus.  Thanks to Wei Chiang
          <chiang@tele.nokia.fi> for these fixes.

        * ace/Connector.cpp (create_AST): Changed the order of some
          instructions in Connector::create_AST method to make it more
          safer to use in multi-thread environment.  Thank to Paul Han
          <phan@CCGATE.HAC.COM> for reporting the problem and the fix.

        * ace/Connector.cpp (create_AST): Make sure to pass in the "mask"
          when calling remove_handler() so that we get the right set of
          bits removed from the Reactor.

        * tests/Reactor_Timer_Test.cpp (class Time_Handler): Changed int
          to long to avoid type conversion problems on 64 bit SGI.  Thanks
          to Fred LaBar <flabar@fallschurch.esys.com> for reporting this.

        * examples/Reactor/FIFO: Added a test program to illustrate the
          interaction of the ACE Reactor with the FIFO IPC mechanism.
          Thanks to Johannes Gutleber <Johannes.Gutleber@cern.ch> for this
          test.

        * examples/Reactor/Misc/pingpong.cpp: Added support for Chorus.
          Thanks to Wei Chiang <chiang@tele.nokia.fi> for this.

        * ace: Added a number of minor changes to signal assignment
          code so that ACE will compile with Tandem NonStop.  Thanks
          to Jan Perman <uabjjpp@osd.ericsson.se> for these fixes.

        * ace/config-tandem.h:  Added a new config file for the
          Tandem NonStop-UX 4.2MP platform.  Thanks to Jan Perman
          <uabjjpp@osd.ericsson.se> for contributing this.

        * include/makeinclude/platform_tandem.GNU:  Added a new platform 
          file for the Tandem NonStop-UX 4.2MP platform.  Thanks to
          Jan Perman <uabjjpp@osd.ericsson.se> for contributing this.

        * ace/config-unixware-2.1.2-g++.h: Added a new config file for
          UNIXWARE 2.1.2.  Thanks to Ganesh Pai (gpai@voicetek.com) for
          contributing this.

        * include/makeinclude/platform_unixware_g++.GNU: Updated the
          UNIXWARE platform config file to work for version 2.1.2.  Thanks
          to Ganesh Pai (gpai@voicetek.com) for contributing this.

        * ace/Handle_Set.cpp (count_bits): Added another 0xff mask to
          prevent problems with sign extension on machines with 32 bit
          ints and 64 bit longs.  Thanks to James Johnson for reporting
          this.

        * ace/OS.h: Updated all of the ACE_DEFAULT* macros in OS.h so that
          they can be overridden by #defines in the config.h file.  Thanks
          to Chuck Gehr for suggesting this.

Thu Jun 19 22:20:20 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h (VxWorks/g++ only): added horrible hack to work around
          mismatch of memcmp, etc., prototypes in <string.h>.

        * ace/OS.i: reordered many function definitions to avoid use
          before definition.  Building with g++ 2.7.2 on VxWorks 5.3.1
          revealed them.

        * ace/config-vxworks5.2-g++.h: removed ACE_HAS_STRING_CLASS and
          ACE_HAS_GNU_CSTRING_H, because those aren't distributed with
          Tornado 1.0.1.

Thu Jun 19 15:31:53 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * ace/Timer_Wheel_T.cpp: Fixed problem with expire () not
          expiring timers with a timeout of the current time. This was
	  causing problems with Timer_Queue_Test when high profile
	  timers were disabled (such as Windows NT when the
	  environment variable ACE_SCALE_FACTOR was undefined)

Wed Jun 18 19:43:35 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Signal.cpp: 'removed "const" from #define of
          ACE_MAX_SIGNAL_HANDLERS because it broke Irix 6.2 build.  Thanks
          to Gonzalo A. Diethelm <gonzo@ing.puc.cl> for reporting this.

        * examples/Threads/task_four.cpp (Invoker_Task::svc): fixed typo,
          n_tasks instead of ntasks.

Wed Jun 18 11:25:14 1997  Nanbor Wang  <nw1@lambada.cs.wustl.edu>

        * examples/Threads/{task_four,token}.cpp: Changed the use of
          cerr/cout to ACE_DEBUG macro.  Thanks to Chuck Gehr
          <gehr@sweng.stortek.com> for pointing these out.
        
Tue Jun 17 15:11:09 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-sunos5.5-sunc++-4.x.h,
          include/makeinclude/platform_sunos5_sunc++.GNU: support enabling of
          exception handling via "exceptions=1" make flag.  Exception handling
          does seem to work with Sun C++ 4.2, even on MP machines, if patch
              104631-02 "C++ 4.2: Jumbo Patch for C++ 4.2 on Solaris SPARC"
          is applied.  Please beware that enabling of exception handling can
          adversely affect peformance, even if the program doesn't use it.
          So, we haven't enabled it by default.  Thanks to Chris Cleeland
          for suggesting not to enable it by default.

        * ace/IOStream.h: added #include of "ace/config.h" so that
          ACE_LACKS_ACE_IOSTREAM can be checked.  Thanks to Ganesh Pai
          <gpai@voicetek.com> for reporting this problem.

        * ace/ACE.cpp (get_handle): use /dev/udp instead of /dev/ip on
          SVR4 machines because it has other read permission by default
          (on Solaris 2.x).

        * ace/ACE.cpp (get_ip_interfaces): use auto_array_ptr instead of
          auto_ptr so that the array gets deleted properly, and zero it
          out to avoid unitialized memory read reports from Purify.

        * ace/Timer_Hash_T.cpp (cancel): added "[]" to delete of timer_ids
          array.  Purify rules.

        * Timer_Queue_Test.cppc (test_performance): added "[]" to delete of
          times array.  Purify rules.

Tue Jun 17 15:31:01 1997  Steve Huston  <shuston@riverace.com>

        * ace/ACE.cpp: Fixed get_ip_interfaces (and count_interfaces) to
          work properly on HP-UX (and probably other similar UNIXes).  Needed
          to work with non-IP interfaces present, and fixed to copy the
          IP address without the fudge factor being applied.

Tue Jun 17 14:02:01 1997  Nanbor Wang  <nw1@lambada.cs.wustl.edu>

        * ace/{Free_List.h,Free_List.cpp,Timer_Queue_T.h}: Added #include
          "ace/Synch_T.h" to Free_List.h and removed related inclusion
          from Free_List.cpp and Timer_Queue_T.h.  Thanks to
          Jack Erickson <jack@cibc.com> for reporting this problem.

Tue Jun 17 09:41:48 1997  David L. Levine  <levine@cs.wustl.edu>

        * tests/Enum_Interfaces_Test.cpp: changed name of log file to match
          the program name, so that the one-button test can easily find it.

Tue Jun 17 04:58:38 1997  Nanbor Wang  <nw1@lambada.cs.wustl.edu>

        * ace/Timer_Queue_T.h: Added include file "ace/Synch_T.h" to avoid
          compilation errors in SC 4.1.  We didn't notice this because
          most of us have moved to SC 4.2.  Don't know why this didn't
          cause any problem in SC 4.2.  Thanks to Jack Erickson
          <jack@cibc.com> for reporting this bug.

Mon Jun 16 22:25:18 1997  Steve Huston <shuston@riverace.com>

        * ace/ACE.cpp: Fixed conditional compiles to compile the 
          interface counting code for HP - it reports 0 interfaces,
          so it needs more debugging still.

        * include/makeinclude/platform_hpux_aCC.GNU: added -g to link
          command for building shared library.

        * tests/Buffer_Stream_Test.cpp: fixes to execute correctly and only
          fail assertions on real failures.

Mon Jun 16 19:05:13 1997  Steve Huston <shuston@riverace.com>

        * ace/Free_List.cpp: added #include ace/Synch.h, needed by
          Free_List.i.  Fixes compile errors on HP-UX.

Mon Jun 16 10:59:55 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * ace/Timer_Wheel_T.cpp: Changed expire () so it doesn't
	  access past the end of an array when it finds nothing to
	  expire.  Thanks to Norbert Rapp
	  <norbert.rapp@nexus-informatics.de> for catching this.

Sun Jun 15 03:44:21 1997  Nanbor Wang  <nw1@dingo.wolfpack.cs.wustl.edu>

        * examples/Threads/thread_specific.cpp (worker): Changed the
          output of diagnostics from using cout to using printf.  Also
          corrected several portability problems.  Thanks for Chuck Gehr
          <gehr@sweng.stortek.com> for pointing these out.
        
        * ace/OS.i (thread_mutex_trylock): Corrected the code for NT.  Now
          this function returns 0 if lock is obtained and -1 otherwise.
          Thanks to Robert V. Head <rhead@virtc.com> for noticing this.

        * performance-tests/Synch-Benchmarks/Synch_Tests.{mdp.mak}:
          Added project workspace and makefile for NT to this directory.
        
        * performance-tests/Synch-Benchmarks/svc.conf: 
        * performance-tests/Synch-Benchmarks/{Options,Benchmark}.h:
        * performance-tests/Synch-Benchmarks/*.cpp: Reworked these
          files to have them compiled on NT.

Sat Jun 14 03:53:13 1997  Nanbor Wang  <nw1@dingo.wolfpack.cs.wustl.edu>

        * performance-tests/Synch-Benchmarks/pipe_proc_test.cpp (class
          Pipe_Proc_Test): Changed the type of pipe_handles[] from int to
          ACE_HANDLE.

        * performance-tests/Synch-Benchmarks/sysvsema_test.cpp: When
          creating the semaphore, explicitly cast the key value to (key_t)
          since NT couldn't handle the conversion.

Fri Jun 13 19:32:03 1997  Steve Huston <shuston@riverace.com>

        * ace/ACE.cpp: Fixed count_interfaces to compile on non-SVR4
          systems such as HP-UX.  Not tested yet.

        * ace/OS.i: Fixed mis-arranged conditional compile for HP-UX in
          asctime_r.

Fri Jun 13 03:13:51 1997  Nanbor Wang  <nw1@dingo.wolfpack.cs.wustl.edu>

        * ace/config-win32-common.h: Added a "pragma comment" directive to
          direct MSVC to link in mswsock.lib automatically.  Thanks to
          Bill Tang <btang@magellan.com> for reminding this.

        * ace/ace.{mak,mdp}: Removed explicit inclusion of mswsock.lib.
          Thanks to Bill Tang <btang@magellan.com> for reminding this.

        * examples/OS/Process/Process.{mdp,mak}: For some reasons, I got
          an "unknown link error, please refer to documentation for
          appropriate technical supports" when building this example on NT
          (didn't help much, did it?)  Reassigning the linked library
          solved the problem.

        * examples/OS/Process/process.cpp: Updated class name
          ACE_ProcessEX to ACE_Process because ACE_ProcessEX no longer
          exists.  Also, all exec'ed programs' absolute names have been
          changed and let the environment variable "path" to decide which
          program(s) to exec.

Thu Jun 12 15:48:16 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/ACE.cpp (get_ip_interfaces): Corrected code in the BSDish
          section so that it at least compiles on Linux.  I haven't tested
          this AT ALL.

        * ace/Timer_Queue_T.cpp (calculate_timeout): When this was called
          with the default argument from handle_events(), max_timeout was
          passed as zero, which would cause a SEGV when attempts were made
          to deref it.  Added protection to simply return a zero ptr in that
          case.

Thu Jun 12 13:18:03 1997  Steve Huston <shuston@riverace.com>

        * ace/OS.{h,i,cpp}: Changes for HP-UX 10 primarily.  Threads
          support for DCE Draft 4 threads (bundled with HP-UX 10).
          Correct usage of reentrant C library functions for HP-UX.

        * ace/OS.i: Changed timeout argument to 2nd select function to
          allow the compiler to pick a conversion operator.  As it was,
          HP compiler would not compile it.

        * ace/Service_Object.cpp: When deleting the service memory pointed
          to by a void *, use "operator delete" rather than deleting a void,
          which is prohibited by the current ANSI C++ draft.

        * ace/config-hpux-10.x.h: This is now a compiler-independent header
          file, and is included by config-hpux-10.x-hpc++.h.  This file
          contains all correct settings for HP-UX 10.x, and compiler-specific
          config files should use this - see config-hpux-10.x-hpc++.h.

        * ace/config-hpux-10.x-hpc++.h: New config file for either of the HP
          compilers (HP C++ or HP aC++).  It figures it out internally, and
          uses config-hpux-10.x.h for OS details.

        * include/makeinclude/rules.lib.GNU: Allow for doing a PRELIB step
          when building a shared library, and not using .shobj/*.so files.
          This allows HP aC++ to close all template instantiations for the
          entire library at once, rather than separately, reducing the
          size of the resultant library significantly.

        * include/makeinclude/platform_hpux-aCC.GNU: build libraries with
          templates instantiated all at once.  Compile with flags for using
          the reentrant versions of C library functions.

Wed Jun 11 15:20:15 1997  Nanbor Wang  <nw1@merengue.cs.wustl.edu>

        * ace/Timer_Queue_T.{h,cpp} (calculate_timeout): Changed the
          second parameter the_timeout from a ref. to a ptr. to a ptr in
          order to avoid compilation warning.  Since the pointer itself is
          not modified within the function, it's ok to change this. 

        * ace/Reactor.cpp (wait_for_multiple_events): Added ACE_Time_Value
          the_timeout as a place holder for timeout value when
          max_wait_time is NULL.  Otherwise,
          Timer_Queue::calculate_timeout won't process the timer queue
          even it's not empty.

Wed Jun 11 11:14:29 1997  James C Hu  <jxh@lambada.cs.wustl.edu>

        * include/makeinclude/platform_mvs.GNU (RANLIB):  Requested change
          from Check Gehr (gehr@sweng.stortek.com), RANLIB = echo

Wed Jun 11 04:47:52 1997  Nanbor Wang  <nw1@dingo.wolfpack.cs.wustl.edu>

        * ACE.cpp (count_interfaces): Two bugs were corrected here.  Both
          were typo.

        * tests/Timer_Queue_Test.cpp: Added include file ace/Timer_Queue.h

Tue Jun 10 16:02:52 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * ace/SString.{h,cpp}: Changed the parameters in CString::substring()
          and WString::substring().  Removed const and changed length to a
          ssize_t because of signed/unsigned comparison warnings.

        * ace/ACE.cpp: Changed a loop variable in get_ip_interfaces() to 
          a size_t because of a signed/unsigned comparison warning.

Tue Jun 10 12:47:49 1997    <irfan@TWOSTEP>

        * ace/SString.cpp (operator = and operator +=): There were two
          bugs here.  operator= forgot to tack on the NULL terminator
          after the memcpy() and operator+= appended the second string
          incorrectly. Thanks to Michael R. MacFaden <mrm@cisco.com> for
          pointing these out.

Tue Jun 10 12:16:04 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * ace/Makefile: Updated to reflect newly added files

        * ace/Proactor.cpp: Removed template specializations.

        * ace/Reactor.cpp: Removed some template specializations.

        * ace/Timer_Hash.h: Added an include for Timer_Heap.

        * ace/Timer_Hash_T.cpp: Changed a reference to ACE_Timer_Node
          to ACE_Timer_Node_T<TYPE>

        * ace/Timer_{Hash,Heap,List,Wheel}_T.h: Changed #include 
          "ace/Timer_{...}.h" to "ace/Timer_{...}_T.h".

        * ace/Timer_Queue.cpp: Removed some template specializations.

        * ace/Timer_Queue.h: Removed the including of Timer_Queue.cpp
          since there are no templates to warrant it. 

        * ace/Timer_{Hash,Heap,List,Wheel}.cpp: Added these and put the
          appropriate template specializations here.

Tue Jun 10 02:08:25 1997  Nanbor Wang  <nw1@siesta.cs.wustl.edu>

        * examples/Log_Msg/README: Revised.

        * examples/Log_Msg/test_log_msg.cpp: Revised program output so
          that it's clearer to explain.

Mon Jun 09 15:46:41 1997    <irfan@TWOSTEP>

        * OS.i (mutex_lock): When WaitForSingleObject returns
          WAIT_ABANDONED, the lock is held by the calling thread.
          Therefore we must return 0 from the method.  I have added a new
          mutex_lock() method that takes an extra "abandoned" parameter.
          This is set wehen the mutex is abandoned.  Thanks to Dieter
          Quehl <dietrich.quehl@med.siemens.de> for pointing this out.

Mon Jun  9 02:31:36 1997  Nanbor Wang  <nw1@siesta.cs.wustl.edu>

        * tests/Sigset_Ops_Test.cpp (main): Comment out testing of invalid
          sigset checking for most platforms don't seem to support it.
          Perhaps the ACE's sigset* functions should remove this check for
          compatibility.  

Sun Jun  8 11:39:06 1997  Douglas C. Schmidt  <schmidt@mambo.cs.wustl.edu>

        * ace/OS.i (set): There was a typo here where 

          ((long) (d - (double) l)) * 1000000

          should be 

          (long) ((d - (double) l) * 1000000)

          since otherwise the values are always 0.  Thanks to Jim Crossley
          <jim@lads.com> for reporting this.

        * tests/Enum_Interfaces_Test.cpp (main): Changed ACE_UINT32 to
          size_t to be consistent with the class definition.  Thanks to
          Nanbor Wang for reporting this.

        * ace/Token.h: Added some no-op method for ACE_Token so that it
          will still compile even if ACE_HAS_THREADS isn't defined.

Sun Jun  8 01:37:52 1997  Nanbor Wang  <nw1@siesta.cs.wustl.edu>

        * examples/Log_Msg/README: Added a README file.

        * tests/Sigset_Ops_Test.cpp (main): bug fixed.


Sat Jun  7 16:40:22 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/SString.h (string.): Added a substring() member function to
          ACE_*String classes.  Thanks to Michael MacFaden <mrm@cisco.com>
          for contributing this.

        * ace/ACE: Added a new method called

          int get_ip_interfaces(count, address_array) 

          which will query the OS kernel for the IP addresses for each network
          interface found and return a count and array of ACE_INET_Addr objects.
          The reason for adding this method is that most client apps
          assume gethostbyname(uname|gethostname)) will work.  If the
          nameservices is misconfigured/broken or the machine is multi-homed,
          the client apps have alot of coding to do to figure out if an inteface
          represents a local address or not.  On UNIX, this includes
          the loopback addr. On NT, the loopback addr is not added
          (but may change the impl if others think this useful).
          Thanks to Michael MacFaden <mrm@cisco.com> for contributing
          this.

        * ace/Synch[_T]: Changed all the classes so that internal instance
          variables are now protected rather than private.  This allows
          greater flexibility if there's a need to subclass
          (which shouldn't occur very much...).  Thanks to
          Reza Roodsari <reza@sprynet.com> for suggesting this.

Fri Jun 06 21:30:57 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Timer_{Hash,Wheel}_T.cpp:  added #includes of
          ace/High_Res_Timer.h.  Also, in Timer_Wheel_T.cpp (cancel),
          moved the declaration of "i" out of the loop because it's
          used in two different loops.

Fri Jun 06 17:11:13 1997    <irfan@TWOSTEP>

        * OS.i (sleep): If ACE_POLL_IS_BROKEN is defined, use select() to
          do micro second sleeps.

        * ace/CORBA_Handler.h (ACE_CORBA_*): The new version of Orbix
          (2.2C01) on NT finally supports namespaces.  So now the macros
          ACE_CORBA_n need to be defined using the "::" and not the "_"
          for NT if the new Orbix is being used. Thanks to John Morey
          (jmorey@tbi.com) for the changes.

Fri Jun 06 02:16:08 1997    <nw1@COYOTE>

        * Sigset_Ops_Test.cpp: Added to test correct implementation of
          sigset manipulating functions. 
        
        * run_tests.{sh,bat}, Makefile: Added Sigset_Ops_Test.

Thu Jun 05 20:32:39 1997  David L. Levine  <levine@cs.wustl.edu>

        * tests/Timer_Queue_Test.cpp (randomize_array): removed static
          qualifier now that it's a template function.  It caused a warning
          with Sun C++.

Thu Jun 05 18:28:36 1997    <irfan@TWOSTEP>

        * ace/Asynch_Acceptor.cpp (open): The Proactor was beening passed
          implicitly. I have made this explicit by making this a parameter
          to open. Thanks to MehulM@spa-marketing.com (Mehul Mahimtura)
          for this.

Thu Jun  5 12:06:45 1997  Chris Cleeland  <cleeland@merengue.cs.wustl.edu>

        * ace/Timer_Queue_T.h (ACE_Timer_Queue_T): Overloaded
          calculate_timeout with a version that accepts a pointer to
          storage for the ACE_Time_Value as an argument.  This has a small
          performance win over the other b/c it does not take a lock.  The
          change was made after examining Quantify output for TAO and
          observing that this lock caused
          Reactor::wait_for_multiple_events() to consume a substantial
          percentage of processing time.

        * ace/Reactor.cpp (wait_for_multiple_events): This now uses a
          different version of calculate_timeout() that doesn't require
          taking a lock.

Thu Jun 05 08:48:49 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Reactor.cpp: added template specializations.

        * ace/Timer_Queue_T.cpp (ACE_Timer_Queue_T ctor): rearranged
          initializers to match declaration order.

Thu Jun  5 06:08:06 1997  Nanbor Wang  <nw1@dingo.wolfpack.cs.wustl.edu>

        * ace/OS.i (sigaddset, sigdelset, sigismember): NSIG itself is
          invalid and must be excluded.

Wed Jun 04 21:24:35 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-sunos5.5-g++.h: fixed typo: #define instead of
          #defined ACE_HAS_CLOCK_GETTIME.

        * ace/config-sunos5.5-sunc++*.h: Combined
          config-sunos5.5-sunc++-4.x.h and config-sunos5.5-sunc++-4.1.h,
          and removed the latter.  The Orbix config file now #includes
          config-sunos5.5-sunc++-4.x.h and adds its differences.

        * include/makeinclude/platform_sunos5_sunc++*.GNU: Combined
          platform_sunos5_sunc++.GNU and platform_sunos5_sunc++-4.1.GNU,
          and removed the latter.  platform_sunos5_sunc++_orbix.GNU now
          includes the non-orbix file and adds its differences.  Also,
          added optional CC -fast support.  To enable, just add "fast=1"
          to your "make" invocation.

Wed Jun 04 12:21:41 1997    <irfan@TWOSTEP>

        * tests: Made the following config files consistent:
          UNIXclerk.conf UNIXtokens.conf Win32clerk.conf Win32server.conf
          Win32tokens.conf

        * ace/OS.h: Made sure that some #defines were guarded for
          redefinition specially for the Bristol (that provides Win32 API
          on AIX) headers. Thanks to Rich Christy (rchristy@cccis.com) for
          suggesting these changes.

        * ace/Handle_Set.h: Changed the type of handle_index from int to
          u_int on Win32.  Thanks to Jack Erickson (jack@cibc.com) for
          suggesting this.

        * ace/FILE.h (ACE_FILE_STREAM): Fixed this #define from
          ACE_FILE_Stream to ACE_FILE_IO.

Tue Jun  3 21:23:48 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Timer_{Queue,Hash}: Fixed some uses of template typedefs
          since GCC is too lame to handle them correctly.  Therefore, I
          had to expand TIMER_QUEUE into the ugly fully expanded name.

        * ace/Timer_Queue_T.cpp: Moved the implementation of
          ACE_Event_Handler_Handle_Timeout_Upcall from Timer_Queue.* into
          Timer_Queue_T.* since only template classes should go into *_T.*
          files.

Tue Jun  3 18:16:02 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * ace/Timer_Queue.*:

          Templatized ACE_Event_Handler_Handle_Timeout_Upcall with LOCK
                
          Added deletion() to Upcall Functors.  This gets called if there
          are any nodes in a queue and the queue's destructor is called

        * ace/Timer_Queue_T.*:

          Changed iterator accessor to public

          Removed two template parameters from ACE_Timer_Node_T so only
          EVENT is left.  Added accessors instead of using friendships,
          and deleted the constructor (use set() instead)

          Changed iterator into a general iterator (with first(), next(),
          isdone() and item () methods)
          
          Added remove_first () method that removes and returns the
          earliest timer in the queue
          
          Added ACE_Free_List support

        * ace/Timer_Heap*:

          Added upcall functor deletion() support

          Added remove_first () method that removes and returns the
          earliest timer in the queue
          
        * ace/Timer_List*:

          Changed to double-linked circular list and changed the timer_id
          to be a pointer to the node (like it is in Timer Wheel and Timer
          Hash)

          Added upcall functor deletion() support

          Added remove_first () method that removes and returns the
          earliest timer in the queue
          
          Added check for timer_id of -1 so we don't try to delete the
          error code if it is passed into cancel

          Changed Timer_List_Iterator_T constructor parameter from list to
          listParm to resolve a conflict with STL.  Thanks to Todd
          Barkalow <barkate@louisville.stortek.com> for this fix

        * ace/Timer_Wheel*:
          Added HighRes timer support
	  
          Added upcall functor deletion() support
	  
          Added earliest_pos_ variable to keep track of the list with
	  the earliest node

          Created an expire that is specialized for ACE_Timer_Wheel

          Added remove_first () method that removes and returns the
          earliest timer in the queue
          
          Added check for timer_id of -1 so we don't try to delete the
          error code if it is passed into cancel

        * ace/Timer_Hash*:

          Added Timer Hash Queue - This is a class that can take another
          timer queue type (Timer List, Timer Heap...) as a template
          parameter (BUCKET) and then do an intermediate hash of a timer
          to determine which queue among a table of timer queues to put
          the timer into.  ACE_Timer_Hash is typedefed to the Timer List
          version and ACE_Timer_Hash_Heap is typedefed to the Timer Heap
          version

          Added HighRes timer support

          Added upcall functor deletion() support

          Created an expire that is specialized for ACE_Timer_Hash

          Added remove_first () method that removes and returns the
          earliest timer in the queue
          
          Added check for timer_id of -1 so we don't try to delete the
          error code if it is passed into cancel

        * ace/Free_List.*

          Added ACE_Free_List<T> and ACE_Locked_Free_List<T, LOCK>.  These
          are used to maintain free lists of nodes. ACE_Free_List is a
          abstract class where ACE_Locked_Free_List is a concrete one that
          has a mutex parameter (LOCK).

        * ace/OS.h:

          Added ACE_DEFAULT_TIMER_HASH_TABLE_SIZE constant

          Added ACE_DEFAULT_FREE_LIST_* constants

        * ace/Proactor.*:

          Added deletion() to Upcall Functors.  This gets called if there
          are any nodes in a queue and the queue's destructor is called.

        * tests/Timer_Queue_Test.cpp:

          Added HighRes timer support

          Changed the array of timer queues into a list (to more easily
          add/remove/comment out an entry)

          Added some more performance tests with randomization

Tue Jun  3 00:26:06 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.h: Changed the access protection for ACE_cond_t,
          ACE_sema_t, ACE_event_t, and ACE_rwlock_t so that it is
          protected rather than private.  In addition, added ACE_Export to
          all of these classes so that they are visible outside of a DLL.
          Thanks to Ivan Murphy for these suggestions.

        * ace/OS.h: Changed the value of ACE_MAX_DEFAULT_PORT on Win32 to
          0 in order to work around a nasty NTism...  Thanks to Jon Biggar
          <jon@sems.com> for reporting this.

Mon Jun  2 16:29:48 1997  James C Hu  <jxh@lambada.cs.wustl.edu>

        * ace/Process.*:
          - Fixed ACE_Process::spawn to close descriptors after having
          been duped.
          - Fixed ACE_Process::spawn to exit () after an error is
          encountered in the child process, rather than returning.
          - Fixed ACE_Process_Options::set_handles to duplicate handles
          that are passed in, and then to close them in the destructor.

Sun Jun 01 22:21:28 1997  David L. Levine  <levine@cs.wustl.edu>

        * examples/Threads/tss1.cpp: made some globals non-static or
          const so that tss1 will link with Sun C++ 4.2 -O3.  I don't
          know what the problem is; it only shows up with optimization
          enabled.  These fixes work around it.

Sun Jun 01 20:29:20 1997  James CE Johnson <jcej@lads.com>

        * ace/IOStream*:
          - removed the old 4/5/97 comments
          - made operator>>, << on QuotedString a template

          This last makes QuotedString much more functional.  As
          templated functions, the QuotedString can now be used on
          other iostream-type objects.  The previous method of
          defining the function only for the type of ACE_IOStream
          being created was didn't provide this flexibility.

Sat May 31 07:01:22 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Log_Msg.cpp (open): To avoid handle leaks, we need to
          shutdown the message_queue before trying to reopen it.  Thanks
          to Per Andersson for this suggestion.

        * include/makeinclude/platform_osf1_4.0.GNU: Added a new platform
          config file.  Thanks to James Johnson for this.

Fri May 30 16:25:25 1997    <irfan@TWOSTEP>

        * CPP-inclient.cpp (main): Properly compare to the "quit"
          string. Thanks to "Andre Arpin" <arpin@adan.kingston.net> for
          reporting this.

        * tests/UPIPE_SAP_Test.cpp (connector): Changed the eof marker in
          the strings.

Fri May 30 14:04:44 1997  James C Hu  <jxh@lambada.cs.wustl.edu>

        * include/makeinclude/platform_irix6.4_sgic++.GNU: added to make
          things compile on latest SGI machines.  Removed +pp and -woff...
          flags from the CCFLAGS variable.  Added new -woff flags to hide
          other warnings.

        * ace/config-irix6.4-sgic++*.h: copied corresponding configs from
          irix6.2 and removed ACE_HAS_SVR4_TIME, since this seems to be no
          longer true of irix6.4.

Fri May 30 02:39:39 1997    <irfan@TWOSTEP>

        * ace/Connector.cpp 
          
          (create_AST): On Win32, added the except mask when registering
          with the Reactor to find out when asynchronous connects
          complete.

          (Svc_Tuple): Made sure that the default value for the timer_id
          in AST is not 0. 0 is a valid timer_id. I have changed this to
          be -1.

          (handle_exception): Added this method. On
          Win32, the except mask must also be set for asynchronous
          connects.

Thu May 29 21:28:25 1997    <harrison@samba.cs.wustl.edu>

        * Process.*: Removed the ACE_Process_Old class.

        * Local_Tokens_T.*: Removed all these files.  They have not been
          used by the token library for some time.  They were mistakenly
          put in the release.

Thu May 29 02:00:14 1997    <irfan@TWOSTEP>

        * ACE.cpp (is_process_active): Added this method which checks if a
          process is still alive. Thanks to Chris (CLahey@cccis.com) for
          this code. 

        * ace/OS.i (kill): Changed PROCESS_ALL_ACCESS to
          PROCESS_TERMINATE.

        * ace/ACE.cpp (bind_port): Changed the implementation of this
          method such that a recently used port is not used again in the
          next call to this method on Win32, i.e., upper limit is
          decreased even in the successful case. This fixes the problem on
          Win32 where binding to a recently used port works but the
          following connect fails.

        * ace/Acceptor.cpp (close): Added a close method that allows us
          to shutdown the Acceptor (without having to destroy it).

        * ace/Connector.cpp (close): Added a close method that allows us
          to shutdown the Connector (without having to destroy it).

        * apps/Gateway/Gateway/Proxy_Handler_Connector.cpp

          (handle_close): Removed this method. This code seemed to be
          duplicating the code in the handle_close of the proxies.

          (initiate_connection): Removed the code that did
          rescheduling. The proxies are responsible for this.

        * apps/Gateway/Gateway/Event_Channel.cpp

          (initiate_proxy_connection): Must *always* use the correct synch
          options while connecting.

          (reinitiate_proxy_connection): Always register for timeouts if
          we are not disconnecting. This allows us to remove duplicated
          logic in Proxy_Handler_Connector. 

          The new logic of close() allows us to remove the code that use
          to remove the proxy from the map to prevent double deletes.

          (close): Changed the shutdown logic to: Tell everyone that the
          spaceship is here (behind the comet), close down the connector,
          close down the acceptor, tell everyone that it is now time to
          commit suicide.

        * apps/Gateway/Gateway/Proxy_Handler.cpp (handle_timeout): Must
          return 0, or else the timer queue will cancel the handler and
          *all* its timeouts.

        * apps/Gateway/Peer/svc.conf,Makefile: We now generate a Peer
          shared library (instead of just an .so). The svc.conf was
          changed to reflect this.

        * tests/UPIPE_SAP_Test.cpp: Fixed output message.

        * Handle_Set.i (operator): Fixed typo.

Thu May 29 11:09:52 1997  David L. Levine  <levine@cs.wustl.edu>

        * include/makeinclude/rules.local.GNU: check for directory
          write permission before attempting to install.  This helps
          support shared ACE workspaces.  There are two easy ways
          to not install "private" libraries in the shared workspace:
          1) remove write permission from $WRAPPER_ROOT/ace, or
          2) add "INSTALL=" to invocations of "make".

Thu May 29 06:07:18 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.i (thr_join): Revised some code in the #ifdef'd out
          version of ACE_OS::thr_join() so that it will compile correctly.
          Note that this code isn't currently used, but someday it will
          be.  Thanks to Hamutal Yanay for reporting this.

Wed May 28 16:37:57 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.{h,i} (ACE_Time_Value): added default constructor,
          which does not call normalize ().  ACE_Time_Value::normalize ()
          was showing up as a relatively minor, but signficant hot
          spot in Event Channel latency tests.

Wed May 28 16:02:53 1997  James C Hu  <jxh@lambada.cs.wustl.edu>

        * ace/OS.i: Changes to strdup and getpid for CHORUS, as per Wei
          Chiang's suggestions.

Tue May 27 18:26:51 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/config-hpux-10.x-decthreads.h: Added support for HP/UX 10.10
          with DCE threads.  Thanks to Shankar Krishnamoorthy
          <kshankar@lucent.com> for these fixes.

        * ace/Local_Tokens_T.h: #if def'd out all of this file since it
          doesn't seem to be used anymore.  Thanks to Shankar
          Krishnamoorthy <kshankar@lucent.com> for reporting this.

        * ace/Makefile (TEMPLATE_FILES): Removed Local_Tokens_T since it
          doesn't appear to be used anywhere.

Tue May 27 18:47:34 1997  James C Hu  <jxh@lambada.cs.wustl.edu>

        * tests/*.cpp: Various changes for EBCIDIC compatibility.
          Thanks to Chuck Gehr for pointing out the need for this!

        * tests/test_config.h: Added ACE_ALPHABET to aid a-z sending and
          comparing.

Tue May 27 15:03:25 1997  David L. Levine  <levine@cs.wustl.edu>

        * tests/Future_Test.cpp: added ACE_Future{_Rep}<int> template
          specializations.

Tue May 27 07:49:03 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Future.cpp: Made a few minor reformatting changes to Per's
          new Future enhancements.

Tue May 27 14:19:14 1997  Per Andersson <Per.Andersson@hfera.ericsson.se>

        * ace/Future: Fixed self assignment bug in ACE_Future<>::operator=().
          Fixed bug in ACE_Future<>::set(). It is now possible to do a 
          ACE_Future<>::set() followed by a ACE_Future<>::get() without
          hanging forever.

          Moved all handling of the ACE_Future_Rep<> reference count
          into three new static ACE_Future_Rep<> member functions,
          create, attach, assign and detach.

          Removed one mutex from ACE_Future_Rep<> by changing the
          reference count from an ACE_Atomic_Op<int> into a plain
          int. The ACE_Future_Rep<>::value_ready_mutex_ mutex is
          instead used for serializing changes to the reference count. 
          (ACE_Future_Rep<>::attach, ACE_Future_Rep<>::detach())

          Removed mutex from ACE_Future<> the serialization is
          performed by the ACE_Future_Rep<>::attach,
          ACE_Future_Rep<>::detach() and ACE_Future_Rep<>::assign()
          functions.

          Changed the ACE_Future<> default constructor to always
          create a  ACE_Future_Rep<>

        * tests/Future_Test.cpp: Added test case for
          ACE_Future<>::set() followed by ACE_Future<>::get().  Added
          test for working  ACE_Future::operator=(). The test is not
          fool proof but it crashes or hangs the test process with the
          old ACE_Future<> implementation.

Mon May 26 14:19:14 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * ace/OS.{h,i}: Fixed difftime implementation for cases where
          systems implement it as a macro.  Fixed tempnam by adding
          ACE_LACKS_TEMPNAM.

Sun May 25 11:36:22 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * examples/Reactor/Misc: Removed test_handle_set.cpp since it 
          is now completed subsumed by tests/Handle_Set_Test.cpp.

        * tests/Handle_Set_Test.cpp: Updated the test of
          the ACE_Handle_Set so that it shows how fast the iterator works.

        * ace/Reactor.cpp: Updated the Reactor to use the new
          ACE_Handle_Set_Iterator (whic no longer requires calling
          operator++ to advance the iterator).

        * ace/Handle_Set: Rewrote the ACE_Handle_Set_Iterator to speed it up. 
          The result seems to be about 15% faster than the original.

        * ace/OS.h: Changed the MSB_MASK static constant into a macro and
          moved it from Handle_Set.cpp into OS.h, changing its name to
          ACE_MSB_MASK.

        * ace/Sched_Params.cpp (priority_max): Added another #ifdef for
          Chorus.  Thanks to Wei Chiang for reporting this.

        * include/makeinclude/platform_sunos5_sunc++_orbix.GNU: added -l
          in front of orbixmt.  Thanks to Wei Chiang for pointing this
          out.

        * ace/ACE.cpp: Changed the default port for NT so that it starts
          at 65279 rather than 65535.  Hopefully, this will fix that
          annoying bug that has been plaguing us on NT 4.0 for months.
          Thanks to Goran Lowkrantz <Goran.Lowkrantz@Infologigruppen.se>
          for reporting this.

Sat May 24 23:42:32 1997  David L. Levine  <levine@cs.wustl.edu>

        * performance-tests/Misc/test_naming.cpp (do_testing): replaced
          strlen () calls in character array size with constant expression.

Sat May 24 12:07:48 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * Released version 4.2.1 for testing.

        * ace/Reactor.cpp (bind): Fixed a stupid typo where I was using
          the ACE_REACTOR_EVENT_HANDLER macro instead of the
          ACE_REACTOR_HANDLE macro.  Thanks to Detlef for reporting this.

        * ace/OS.i: Added a new macro called ACE_HAS_THR_MINSTACK to deal
          with weirdo mangling of names by Tandem.  Thanks to Jan Perman
          <uabjjpp@osd.ericsson.se> for reporting this.

        * ace/OS.h: Added a new macro ACE_LACKS_PRI_T for those platforms
          using STHREADS (e.g., Tandem NonStop OS) that don't have pri_t
          defined.  Thanks to Jan Perman <uabjjpp@osd.ericsson.se> for
          reporting this.

        * ace/Connector.cpp (connect): Make sure to save/restore errno
          since svc_handler->close() may change it.  Thanks to Michael
          Hartman <c62nt57@ibx.com> for reporting this.

        * include/makeinclude/platform_chorus.GNU: Added a new platform
          macros file for Chorus.  Thanks to Wei Chang for this.

        * ace/OS.cpp (sched_params): Reordered the #ifdefs so that Chorus
          comes first.

        * ace/OS.i (sleep): If the platform defines ACE_HAS_CLOCK_GETTIME
          then we'll use the nanosleep() method rather than sleep().

        * ace/OS.h: disabled THR_NEW_LWP for Chorus.  Thanks to Wei Chang
          for reporting this.

        * ace/Sched_Params.cpp: ACE_SCHED_OTHER and ACE_SCHED_RR have the
          same value on Chorus.  Thanks to Wei Chang for reporting this.

Sat May 24 09:21:08 1997  David L. Levine  <levine@cs.wustl.edu>

        * netsvcs/lib/Server_Logging_Handler.cpp: protected second
          ACE_Svc_Handler specialization for case that ACE_HAS_THREADS,
          when ACE_HAS_TLI.  It had gotten lost in the last pass of
          that module.  Thanks to Sandro Doro <doros@aureus.sublink.org>
          for reporting this problem.

Sat May 24 03:19:38 1997  Nanbor Wang  <nw1@dingo.wolfpack.cs.wustl.edu>

        * ace/OS.i (sigaddset, sigdelset, sigemptyset, sigfillset,
          sigismember): Modified the implementation of these function so
          as to conform with POSIX standard.  Basically all functions do
          the same things they did but more conservative protections are
          added.  The modified semantic becomes,
          
          sigemptyset, sigfillset, sigaddset, sigdelset:  return 0 if
            succeed, -1 otherwise. 
          sigismember: returns 0 if signum is not in the set, 1 if signum
            is in the set, and -1 if error occurs.

          If error occured, errno will be set to one of the following
          value: 
            EFAULT:  sigset is not a valid address.
            EINVAL:  signum is not a valid signal number.

          Notice that, so far, this is for NT only.

Sat May 24 01:53:22 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * performance-tests/Misc/test_naming.cpp (do_testing): Thanks to
          Sandro Doro, squashed a bug where we were trying to concatenate
          onto a string constant.

Fri May 23 01:01:01 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/config-hpux-9.x.h: Added

          #define ACE_HAS_BROKEN_ENUMS
          #define ACE_HAS_IP_MULTICAST
          #define ACE_LACKS_GETPGID

          Thanks to Neil Cohen for reporting these.

        * ace/Thread_Manager.h: Made the private methods and data members
          protected so that subclasses can extend it.  Thanks to Hamutal
          Yanay for this suggestion.

Fri May 23 21:27:05 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Process.{h,cpp} (env_argv): added "const" to char * type in
          return type, for argument compatibility in call to ACE_OS::execve ().

        * ace/Process.cpp (spawn): removed unreachable return statement at
          end of function.

        Thanks to Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com> for
        reporting the above two problems.

        * ace/{IOStream*,Makefile}: Split out templates into
          ace/IOStream_T.{h,cpp} files.  This way, automatic template
          instantiation systems that require templates to be in separate
          files, such as on Irix 6.2, will be able to build IOStream_Test
          and the ACE_IOStream examples without warnings.  (The
          ACE_IOSTREAM_BUILDING_TEMPLATE macro that did this only worked
          if ACE_TEMPLATES_REQUIRE_SOURCE was defined.  It's no longer
          needed with the separate template files.)

        * tests/IOStream_Test.cpp,
          examples/IOStream/client/iostream_client.cpp,
          examples/IOStream/server/iostream_server.cpp:
          swapped ACE_Streambuf and ACE_Streambuf_T class names so that
          the template class has the "_T".  And renamed ACE_IOStream_T
          for consistency.

        * ace/{IOStream.*,README},
          tests/IOStream_Test.cpp,
          examples/IOStream/client/iostream_client.cpp,
          examples/IOStream/server/iostream_server.cpp,
          config-hpux-9.x*.h:
          Added ACE_LACKS_ACE_IOSTREAM protection
          so that these can easily be built on platforms that have
          trouble with ACE_IOStream.

        * Priority_Task_Test.cpp: removed close () because it didn't really
          close the Task, and added printout to main () after all tasks have
          been spawned to help debug non-termination.

        * ace/OS.cpp: (thr_create, with STHREADS only): *thr_handle was
          used but *thr_id had been set by ::thr_create, so threads never
          got activated.  Fixed by using *thr_id instead of *thr_handle
          in the calls to ACE_OS::thr_setprio and ACE_OS::continue.
          Thanks to Jan Perman <uabjjpp@osd.ericsson.se> for reporting
          this problem.

Fri May 23 20:12:33 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * tests/SV_Shared_Memory_Test.cpp: Thanks to Chuck Gehr, fixed
          ASCII dependent code in the parent and child routines.

Fri May 23 02:58:28 1997  Nanbor Wang  <nw1@siesta.cs.wustl.edu>

        * ace/OS.i (dlsym): Added ACE_USES_ASM_SYMBOL_IN_DLSYM, support
          for platforms (FreeBSD) which use assembly symbols instead of C
          symbols in dlsym ().

        * ace/config-freebsd[-pthread].h: Added flag ACE_HAS_CHARPTR_DL
          and ACE_USES_ASM_SYMBOL_IN_DLSYM.

Thu May 22 08:14:21 1997  David L. Levine  <levine@cs.wustl.edu>

        * tests/Tokens_Test.cpp: added deletes to avoid memory leaks.

Wed May 21 16:15:48 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/{config-irix6.2*.h,README}: removed ACE_LACKS_IOSTREAM_SETGET
          because tests won't build with it.  Also, added
          ACE_LACKS_SIGNED_CHAR.

        * ace/IOStream.h: removed "const" from PUT_PROT of
          u_char * and void *.  This should allow the IOStream test
          and examples to build and run on Irix platforms.  Thanks
          to Torbjorn Lindgren <tl@funcom.com> and Amos Shapira
          <amos@dsi.co.il> for reporting this, and to James Hu for
          helping fix it.

        * ace/{OS.cpp,Sched_Params.cp} (Solaris only): use 0 min priority
          again, with workaround in ACE_OS::thr_create to not use
          ::pthread_attr_setschedparam () if the priority is 0.  Instead,
          the priority of the newly created thread is set to 0 (if it
          wasn't created with 0) after the thread is created, with
          ::pthread_setschedparam ().

Wed May 21 15:23:37 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/Strategies_T.* (ACE_Hash_Addr): Eliminated the ADDR_T
          template parameter as a base class.  It is now a wholly-contained
          member of the ACE_Hash_Addr<> with conversion operators.
          This caused problems on certain compilers, notably HP-UX.

Wed May 21 14:13:36 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * ace/OS.{h,i} (difftime): Added implementation to ACE_OS.  I
          don't expect any problems since it is in ANSI.

        * ace/OS.{h,i} (tempnam): Added implementation to ACE_OS.

Wed May 21 01:17:40 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * Released version 4.2.

        * ace/Acceptor.cpp (activate_svc_handler ): Removed an unnecessary
          return 0.  Thanks to Amos Shapira <amos@dsi.co.il> for reporting
          this.

        * ace/Message_Block.cpp (release): I believe that
          ACE_Message_Block::release() should return something other than
          0, i.e., it should return the result of release_i().  Thanks to
          Amos Shapira <amos@dsi.co.il> for reporting this.

Wed May 21 01:17:40 1997 Per Andersson <Per.Andersson@hfera.ericsson.se>

        * Moved most code from netsvcs/lib/Server_Logging_Handler.* to
          Server_Logging_Handler_T.*.  Made template out of
          ACE_Server_Logging_Handler and ACE_Server_Logging_Acceptor. 
          Factorised out as much as possible to reduce code
          duplication. The log record processing was moved from
          ACE_Server_Logging_Handler it should now be handled by the
          Log_Message_Receiver class. It is now possible to change 
          how log records processed without changing code in
          Server_Logging_Handler* and it is possible to have several
          Server_Logging_Handlers that processes log records
          in different ways without duplicating all the server code.
          All that is needed is to write a new/change
          Log_Message_Receiver and instantiate a couple of templates.

        * netsvcs/lib/Server_Logging_Handler.h added lots of typedefs
          for making template instantiations easier.

        * netsvcs/lib/Server_Logging_Handler.h addad lots template
          instatiations, there are now 58 all together.

        * Added netsvc/lib/Log_Message_Receiver.{h,cpp}, implementstwo
          simple log message receivers that prints the log record to
          stderr. 

Tue May 20 13:50:17 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/config-hpux-9.x.h: Added a #define for ACE_HAS_BROKEN_ENUM,
          ACE_HAS_IP_MULTICAST, and ACE_LACKS_GETPGID.  Thanks to Neil
          Cohen for reporting this.  

        * include/makeinclude/platform_sunos5_sunc++_orbix.GNU: Replaced
          the use of -lITsrv with -lorbixmt.  Thanks to Wei Chiang for
          this.

        * include/makeinclude/platform_osf1_3.2.GNU: Make sure that all
          the template repositories are in the same directory to work
          around problems with the C++ compiler.  Also added -lrt to get
          the apps and tests to run.  Thanks to Tom Dobridge for this
          help.

Tue May 20 17:13:15 1997  Carlos O'Ryan  <coryan@charlie>

        * ace/config-hpux-10.x-nothread.h: 
        * ace/config-hpux-10.x-aCC.h: 
        * ace/Stream_Modules.cpp: 
        ACE_LACKS_STREAM_MODULES is no longer needed, moving the inclusion
        of "ace/Task.h" to the beginning of "ace/Stream_Modules.h" solved
        the problem nicely.

        * ace/config-hpux-10.x.h: 
        * ace/config-hpux-10.x-aCC.h: 
        ACE_HAS_BROKEN_HPUX_TEMPLATES is not needed on newer HP/CXX
        compilers; further, old ones will not compile ACE even if the
        macro is defined.

        * ace/Timer_List_T.h: 
        * ace/Timer_Queue_T.i: 
        I moved the definition of ACE_Timer_Queue_T::lock() from the .i
        file to the .h file, HP/CXX gets completely confused otherwise.
        I also added a number of ACE_INLINE missing in the .i file.

        * ace/Stream_Modules.h: 
        * ace/Stream_Modules.cpp: 
        I had to move the inclusion of "ace/Task.h" outside of the
        protections against multiple inclusion for Stream_Modules.h.
        That seems to solve the ciclyc dependancy for
        Task->Module->Stream_Module->Task.
        BTW, the same thing was already done in "ace/Log_Record.h".
        I'll try to remove the ACE_LACKS_STREAM_MODULES macro, it seems
        that the last change makes it redundant.

        * ace/Signal.cpp: 
        HP/CXX compiler will not close the library unless
        ACE_MAX_SIGNAL_HANDLERS is defined as "const size_t". The previous
        definition ("size_t") did compile tough.

        * ace/Log_Record.h: 
        We need to include "ace/ACE.h" before "ace/Log_Priority.h".

        * ace/Log_Priority.h: 
        HP/CXX compiler seems to reserve a few bits in enums, so the
        ENSURE_32_BITS trick would result in a compile time error.
        Since HP enums are always 32 bits we could skip the definition for
        ENSURE_32_BITS altogether, but I prefer to keep a consistent
        namespace across plaforms, I have found a value for ENSURE_32_BITS
        that seems to work.

        * include/makeinclude/platform_hpux.GNU: 
        Some options to improve compile time, since we use explicit
        template instantiation there is no need for a ptcomp o ptlink
        phase.

Tue May 20 09:10:18 1997  Nanbor Wang  <nw1@number.wustl.edu>

        * ace/config-freebsd-pthread.h: 
        * ace/config-freebsd.h: Removed "FreeBSD" directive because gcc on
          FreeBSD defines __FreeBSD__ automatically.

        * ace/OS.i (sigaddset, sigdelset, sigismember): Added range
          checking to these functions in order to avoid disasters.  Sig
          number should be between 1 and NSIG.
          (sigwait): Changed ifdef (FreeBSD) to ifdef (__FreeBSD__) since
          compiler does it for us.      

Tue May 20 08:41:11 1997  David L. Levine  <levine@cs.wustl.edu>

        * examples/Threads/tss2.cpp: added #include of ace/Thread.h
          because Sun C++ 4.1 needs it.

Mon May 19 16:04:32 1997  David L. Levine  <levine@cs.wustl.edu>

        * bin/create_ace_build: changed startup line for compatibility
          with bash.  This startup line lets the script run without
          hard-coding the full path to the perl executable, as long as
          perl is on the user's PATH.

Mon May 19 12:45:21 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * examples/Threads/reader_writer.cpp: Changed the code so that we
          don't try to treat thread ids as ints!  Thanks to Chuck Gehr for
          reporting this.

Sun May 18 21:57:54 1997  David L. Levine  <levine@cs.wustl.edu>

        * examples/Threads/tss2.cpp: added second parameter to
          ACE_TSS_Singleton template specialization.

Sun May 18 09:20:15 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * examples/Threads/TSS_Data.h: Added the second parameter for
          ACE_SYNCH_MUTEX since Rich and Chris updated ACE_TSS_Singleton.

        * ace/Singleton.cpp: Added the updated version of
          ACE_TSS_Singleton that implements the Double-Checked Locking
          pattern.  Thanks to Rich Christy and Chris Lahey for this.

        * ace/Strategies_T.cpp (activate_svc_handler): Fixed the logic so
          that a value is always returned.  Thanks to David Levine for
          noticing this.

Sun May 18 07:25:11 1997  David L. Levine  <levine@cs.wustl.edu>

        * netsvcs/lib/Server_Logging_Handler.cpp: removed second
          ACE_Svc_Handler specialization for non-threaded, has-TLI case.
          That's because it is the same as the first; the only difference
          was that one specialized with ACE_SYNCH and the other with
          ACE_NULL_SYNCH.  Without threads, those macros expand to the
          same thing.  Thanks Sandro Doro <doros@aureus.sublink.org> for
          reporting this.

        * examples/Threads/tss2.cpp: added ACE_TSS<TSS_Data> template
          specialization.

Sat May 17 23:24:34 1997  Nanbor Wang  <nw1@number.wustl.edu>

        * ace/OS.i (sigismember): Corrected the code when
          ACE_LACKS_SIGSET.

Sat May 17 00:06:04 1997    <irfan@TWOSTEP>

        * examples/ASX/Event_Server/Transceiver/transceiver.cpp
          (Event_Transceiver): Corrected signal registration for Win32.

        * apps/Gateway/Gateway/Gateway.cpp (parse_args): Since the
          Connector is now fixed, non-blocking is now working fine.

        * ace/Connector.cpp (handle_close,create_AST): Made sure we close
          down the svc_handler on error.

        * ace/{Acceptor.cpp,Connector.cpp} (activate_svc_handler): The
          if statement logic in these methods was incorrect.

        * ace/SOCK_Connector.cpp (connect): Just like in complete(), we
          start out with non-blocking disabled on the <new_stream>.

        * ace/OS.h: When ACE_LACKS_SIGSET is defined, changed the
          definition of sigset_t from void * to unsigned int.

Sat May 17 12:25:22 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/{Acceptor,Connector,Strategies_T}: Make sure to either
          enable or disable ACE_NONBLOCK (depending on the flags).  This
          ensures that we always start with the I/O mode set to a
          deterministic state.  Thanks to Irfan for suggesting this.

        * ace/Connector: Added a new "flags" parameter to the 
          ACE_Connector and ACE_Strategy_Connector which keeps track of
          flags that control how Svc_Handler are initialized prior to
          being activated.  

        * ace/Strategies_T.cpp (activate_svc_handler): Make sure to set
          the peer's handle into non-blocking mode *before* calling the
          Svc_Handler's open() method.  This ensures that things are set
          up correctly when this hook is called.

Sat May 17 02:19:27 1997  Nanbor Wang  <nw1@number.wustl.edu>

        * ace/config-freebsd.h (ACE_HAS_BROKEN_TIMESPEC_MEMBERS): 

        * ace/OS.i (set, timestruct_t, nanosleep): 

        * ace/High_Res_Timer.cpp (elapsed_time): 

        * ace/README: Added ACE_HAS_BROKEN_TIMESPEC_MEMBERS so that we can
          fix that problem FreeBSD 2.1.x brings by defining timespec as {
          time_t ts_sec ; long ts_nsec }.  Notice:  This is highly
          non-portable.  Please refer to ACE code and see how to write
          portable.  Fortunately, only older versions of FreeBSD have
          this.  Yesterday's hack didn't work, so, it's removed.  Thanks
          to Satoshi Ueno <satoshi.ueno@gs.com> for reporting and helping
          debug on his FreeBSD 2.1.7R box.

Sat May 17 00:06:04 1997    <irfan@TWOSTEP>

        * apps/Gateway/Gateway/Proxy_Handler.cpp (open): Turn on
          non-blocking I/O only after the Channel is done sending the id
          to the Peer.

        * apps/Gateway/Gateway/Gateway.cpp: 

          - Added necessary DLL build macros. 

          - Removed error checking for Reactor::remove_handler() for STDIN
            as STDIN is never registered with the Reactor on Win32.

          - Fixed the registration of SIGINT.

          - blocking_semantics_ should be 1 when blocking is on and not 0.

          - Since the Connector is currently broken with respect to
            non-blocking connects, I have put a temporary fix such that
            only blocking connects are done. Revert this after the
            Connector is fixed.

        * apps/Gateway/Gateway/Event_Channel.cpp: 

          - Only if socket_queue_size > 0, do we set a new value.

          - In reinitiate_proxy_connection(), we must unbind the proxy
            from the proxy_map_ as we are no longer responsible for
            this. The Connector should now be responsible for this.

        * apps/Gateway/Gateway/Concrete_Proxy_Handlers.cpp: Added
          necessary DLL build macros.

        * apps/Gateway/Peer/Peer.cpp: 

          - Added include file and necessary DLL build macros. 

          - Removed error checking for Reactor::remove_handler() for STDIN
            as STDIN is never registered with the Reactor on Win32.

          - Fixed the registration of SIGINT.

        * apps/Gateway/{Peer,Gateway}: Added Win32 makefiles.

        * ace/ACE.cpp (read_adapter): Handle for the read_adapter should
          always be STDIN.

Fri May 16 18:43:17 1997  Nanbor Wang  <nw1@number.wustl.edu>

        * ace/config-freebsd.h: Minor modification for working on FreeBSD
          2.1.x platform.  Added includion of <sys/time.h> and
          <sys/types.h>.  Defined ACE_HAS_POSIX_TIME for 2.1.x.  Redefine
          timespec to timeval to hack around a bug on 2.1.x.  Thanks to
          Satoshi Ueno <satoshi.ueno@gs.com> for reporting this.
        
Fri May 16 12:25:32 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * netsvcs/lib: Reverted back to the original Server_Logging_Handler 
          behavior since the new version is breaking GCC's templates.

        * ace/Log_Record.h: need to #include "ace/ACE.h" before
          "ace/Log_Priority.h" so that "Log_Priority.h" sees the
          configuration stuff (otherwise the following fix won't work).

        * ace/Log_Priority.h: Added a workaround for lame C++ compilers
          like the one on HP/UX that can't support large enums.  Thanks to
          Robert Head for reporting this.

        * ace/Singleton: Added the new ACE_TSS_Singleton, which stores
          Singletons in thread-specific storage.  Thanks to Chris Lahey
          and Rich Christy <rchristy@cccis.com> for this.

        * ace/OS.h: Removed the ACE_Singleton_Strategy since we don't need
          it anymore.

        * netsvcs/lib: Added the new Server_Logging_Handler_T.* and
          Log_Message_Receiver.* netsvcs.  Thanks to Per Andersson for
          contributing these.

        * examples/Misc/Makefile: Removed the XtReactor tests from the
          Makefile until we figure out a good way to get them integrated
          with the appropriate libraries.

        * ace/config-irix6.2-sgic++-nothread.h: Added the following:

          ACE_LACKS_LINEBUFFERED_STREAMBUF
          ACE_HAS_SETOWN
          ACE_HAS_SYSENT_H
          ACE_HAS_SYSINFO

          Thanks to Torbjorn Lindgren <tl@funcom.com> for reporting
          this.

        * ace/Proactor.cpp: Changed the use of lock() to mutex() since we
          changed the name in Timer_Queue.

        * ace/Timer_Queue_T.i: Changed the name of the lock() method to
          mutex() to work around compile problems with HP/UX.  Thanks to
          Robert Head <rhead@mail.virtc.com> for reporting this
          workaround.

        * ace/config-irix5.3-sgic++.h: Made a few changes to get ACE to
          work on IRIX 5.3.  Thanks to Eugene R. Somdahl <gene@endo.com>
          for these fixes.

        * ace/OS: Added calloc() implementation.  I don't know how
          this managed to fall through the cracks!

        * include/makeinclude/platform_osf1_4.0.GNU: Added a few more
          tweaks courtesy of James Johnson.

        * include/makeinclude/platform_osf1_3.2.GNU: Added a few more
          tweaks courtesy of Tom Dobridge.

        * include/makeinclude/platform_osf1_4.0.GNU (DLD): Added -shared
          -expect_unresolved '*' so that calls to the linker via cxx will
          work correctly.  Thanks to Thilo for this.

        * include/makeinclude/platform_chorus.GNU: Removed CLASSIXDIR =
           /usr/home/chiang/chorus/merge/extended-i386at, added the
           nostdinc flag, and removed extra whitespace.  Thanks to Wei
           Chiang for reporting this.

Fri May 16 00:02:33 1997 <irfan@TWOSTEP>

        * ace/ReactorEx: Even though changes to the owner field are very
          well synchronized within the class code, the owner()
          accessor is public and can be called from out side the
          class. Therefore, I have added a owner_i() that does not do
          locking. All internal calls to check the owner will use the
          new accessor, whereas application code outside the class can
          still use the old synchronized accessor.

Fri May 16 11:39:51 1997  Nanbor Wang  <nw1@cs.wustl.edu>

        * ace/OS.i (sigaddset, sigdelset, sigemptyset, sigfillset,
          sigismember): Added implementation when ACE_LACKS_SIGSET so that
          platforms (NT?) without these functions can still manipulate
          sigset_t variables.

Thu May 15 22:19:59 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * examples/ASX/Event_Server/Event_Server: Removed the THR_DETACHED
          flag from options so that we can wait on the threads
          correctly.

        * ace/Stream_Modules.cpp: Changed the logic for determining when
          to compile the Stream_Modules.cpp code.  Now, we compile it
          unless ACE_LACKS_STREAM_MODULES is defined (i.e., we're on HP/UX
          10.x using aCC).

        * netsvcs/lib/Server_Logging_Handler.cpp (handle_input): Fixed
          a bug in handle_input() where we need to return the result, not 
          just 0 or 1.  Thanks to Per Andersson for reporting this.

        * ace/Log_Priority.h: Changed the values of the enums in
          ACE_Log_Priority so that they can be dealt with via bitwise
          operations.  Thanks to Per Andersson for this.

        * include/makeinclude/platform_osf1_4.0.GNU: Added support for
          templates.  Thanks to Steve Huston and James Johnson for
          verifying this.

        * include/makeinclude/platform_osf1_3.2.GNU: Got rid of all
          unresolved symbol warnings using cxx 5.5 on DEC/OSF v3.2 by
          using the linker flag "-expect_unresolved '*'."  In addition, I
          added -threads to the DCFLAGS macro.  Thanks to Tom Dobridge
          <dobridge@persimmon.com> for this.

        * ace/Strategies_T: Added a minor ACE_Reactive_Strategy extension
          to enable non-blocking I/O in active_svc_handler().  Thanks to
          Arturo Montes <mitosys@colomsat.net.co> for contributing this.

        * ace/config-osf1-4.0[-g++].h: Added a #define for
          ACE_POLL_IS_BROKEN since DEC UNIX's poll() doesn't seem to work
          correctly as a highres timer.  Thanks to James Johnson and Thilo
          for reporting this.

        * examples/Threads/thread_specific.cpp (worker): Changes
          size_t i back to int i to avoid a signed/unsigned complaint.
          Thanks to David Levine for reporting this.

        * ace/config-chorus.h: Added ACE_LACKS_MPROTECT,
          ACE_HAS_IP_MULTICAST, and ACE_LACKS_SOCKETPAIR to the Chorus
          port.  Thanks to Wei Chiang <chiang@erebor.tele.nokia.fi> for
          reporting this.

        * ace/OS.i: Added ACE_LACKS_ACCESS to the Chorus config file
          and VxWorks config file, as well as to OS.i.

:       * ace/OS.i: Added ACE_LACKS_GETSERVBYNAME to the Chorus config
          file and VxWorks config file, as well as to OS.i.

        * ace/OS.i: Added ACE_LACKS_SBRK to the Chorus config file, as
          well as to the definition of the ACE_OS::sbrk() function.

        * ace/OS.h: Removed #include /**/ <pwd.h> from the Chorus-specific
          part of OS.h since it's already included elsewhere.  Thanks to
          Wei Chiang <chiang@erebor.tele.nokia.fi> for reporting this.

        * ace/Reactor: Added a typedef for ACE_Reactor_Token to
          ACE_Null_Mutex for situations where ACE_MT_SAFE is *disabled*.
          This makes the code more consistent.

        * ace/Reactor: Added an interface that makes it possible to
          acquire a reference to the <ACE_Reactor_Token> that is used to
          serialize the internal Reactor's processing logic.  This can be
          useful for situations where you need to avoid deadlock
          efficiently when <ACE_Event_Handlers> are used in multiple
          threads.  Thanks to Detlef for pointing out the utility of this.

Thu May 15 23:34:30 1997  Tim H. Harrison  <harrison@waltz.cs.wustl.edu>

        * ace/Process_Manager.cpp (spawn_n): Changed
          ACE_Process_Manager::start_n to ACE_Process_Manager::spawn_n.

Thu May 15 15:39:13 1997  Carlos O'Ryan  <coryan@charlie>

        * include/makeinclude/platform_hpux.GNU: 
        * ace/config-hpux-10.x.h: 
        * ace/config-hpux-10.x-nothread.h: 
          HP/CXX cannot achieve template closure, not even using the
          dummy exec trick: apparently the repository gets a bit
          corrupted. HP/CXX (version 10.24) support explicit template
          instantiation, I believe this to be a superior method for
          ensuring library closure (and it works).
 
        * ace/Task_T.cpp: 
        * ace/Stream_Modules.cpp: 
          I have changed the hack to compile under HP-UX,
          "ace/Module.h" is once more included in ace/Task_T.cpp, but
          "ace/Stream_Modules.cpp" is protected: it will be empty
          under HP-UX unless included from the
          "ace/Stream_Modules.h". I still believe that there is a
          problem in the cyclic dependancy Task -> Module -> Thru_Task
          -> Task; but it seems that the current hack works better.
 
        * ace/OS.h: 
          Defining ACE_UNUSED_ARG as (a) for HP/CXX does not work so I
          moved it to the SGI and GCC definition.

        * ace/OS.i: 
          More unused args.

        * ace/Handle_Set.h: 
          Removed the extra qualification for ACE_Handle_Set::NBITS,
          HP/CXX sends a lot of warnings with that.
 
        * ace/IOStream.h: 
          It included "IOStream.cpp" I think that "ace/IOStream.cpp"
          is better. 
 
        * ace/Local_Name_Space_T.h: 
          Ditto for "Local_Name_Space.h"

Thu May 15 17:40:06 1997    <irfan@TWOSTEP>

        * ace/ReactorEx.i (owner): Since changes to the owner field are
          very well synchronized, we do not need to synchronize this
          accessor.

        * ace/IOStream.h: Added /**/ after #include directives.
        
        * ace: Update Win32 makefiles to include UNICODE make option.

Thu May 15 08:54:53 1997  David L. Levine  <levine@cs.wustl.edu>

        * Makefile (release, cleanrelease): use -prune option to "find"
          instead of filtering its output.  Thanks to Chris Cleeland for
          suggesting this.

Wed May 14 21:52:22 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/UPIPE_Stream.cpp (control): We need to "cast away const" so
          that this method can call the Stream's control() method
          (which is non-const).  Thanks to David Levine for locating this.

        * ace/Singleton.cpp: Finished re-implementing ACE_Singleton.

        * examples/ASX/Message_Queue/buffer_stream.cpp: Updated this
          example to illustrate (1) how filters work in an ACE_Stream and
          (2) to make sure that resizing buffers work.

        * ace/UPIPE_Stream.h: Changed the signature of control()
          to take an int so that it will match the base class
          signature.

        * ace/Singleton.h: The new ACE_SingletonEx isn't working yet.
          I've #ifdef'd it out until it works.

        * examples/Threads/tss2.cpp: Updated this test program to
          illustrate the use of the new ACE_SingletonEx class.

        * ace/Singleton.h: Added a new instance() method to the ACE
          Singleton that can be used to set the Singleton.  This is useful
          for situations where the type being used as the Singleton
          doesn't have a default constructor.  Thanks to Arturo Montes
          <mitosys@colomsat.net.co> for this suggestion.

        * ace/Singleton: Factored out common code in the Singleton and
          SingletonEx implementations so they will be cleaner and more
          portable.

        * ace/Local_Name_Space_T.h,
          ace/Map_Manager.h,
          ace/Hash_Map_Manager.h,
          ace/SString.h,
          ace/Hash_Map_Manager.cpp: 
        
          Changed all uses of the identifier "allocator" to "alloc" to
          avoid conflicts with MSVC++ STL 5.0.  Thanks to William
          L. Gerecke <gerecke@rayva.org> for reporting this.

        * ace/config-aix-4.[12].x.h: Replaces
          ACE_LACKS_PTHREAD_THR_SIGSETMASK with ACE_HAS_SIGTHREADMASK.
          Thanks to Chris Lahey for this.

        * ace/OS.i (thr_sigsetmask): Added the ACE_HAS_SIGTHREADMASK
          support for AIX.  Thanks to Chris Lahey for this.

        * ace/Singleton: Added the new ACE_SingletonEx, which supports
          both heap-based and thread-specific storage-based Singletons.
          Thanks to Chris Lahey for this.

        * ace/OS.h: Added the new ACE_Singleton_Strategy to OS.h.  Thanks
          to Chris Lahey for this.

Wed May 14 16:32:57 1997  David L. Levine  <levine@cs.wustl.edu>

        * Makefile: use cpio instead of tar to allow easy filtering
          of CVS files from the release.

Wed May 14 15:00:58 1997    <irfan@TWOSTEP>

        * examples/IPC_SAP/SOCK_SAP/CPP-inclient.cpp (main): Fixed code.

        * examples/Naming: Replaced multiple makefiles with one makefile.

        * ace/OS.h: Added UNICODE support for some #defines.

        * OS.i (vsprintf): Added support for this in ACE_OS.

        * OS.cpp (socket_init && socket_fini): It is ok to print out cout
          and cerr messages from here (as the C runtime library is still
          attached) but it is *not* ok to print out ACE_DEBUG
          messages. God only knows the state of the thread specific LogMsg
          instance when the process reaches this piece of code.

          Also added a (handy) sprintf that has the following prototype:

          sprintf (wchar_t *buf, const char *format, ...)

        * ace/Process: UNICODE fixes.

        * tests: Fixed the following such that they work with UNICODE:

          Pipe_Test.cpp 
          Process_Mutex_Test.cpp 
          Process_Strategy_Test.cpp 
          Time_Service_Test.cpp 
          Tokens_Test.cpp

        * Time_Service_Test.cpp (main): Fixed typo in the svc.conf
          filename for the clerk.

Tue May 13 18:56:27 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/IOStream.h: To make C++ compilers happy I added
          the following changes by modifying

          ACE_IOStream & operator>>( ACE_Time_Value *& tv );

          to be

          ACE_IOStream<STREAM> & operator>>( ACE_Time_Value *& tv );

          Thanks to Chuck Gehr for this fix.

Tue May 13 21:32:12 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Process.cpp (~ACE_Process_Options): delete
          command_line_buf_ was missing the [].

        * examples/Threads/process_manager.cpp (main): avoid compiler
          warning due to implicit creation of temporary by explicitly
          creating an ACE_Process_Options instance.  It gets passed to
          ACE_Process_Manager::spawn (ACE_Process_Options &), which
          takes a non-const reference.

Tue May 13 18:08:32 1997    <irfan@TWOSTEP>

        * examples/ASX/UPIPE_Event_Server: Made enough fixes for this to
          compile on Win32 but more work need to be done for this to
          work on Win32.

        * ace/OS.i (kill): The error result for ::OpenProcess() is null
          and *not* invalid handle.

        * ace/Process.i (kill): Changed the implementation to remove the
          ACE_OS::kill() code from ACE_Process::kill() for Win32. This
          allows us to avoid calling ::OpenProcess() unnecessarily.

        * tests: For Win32, added Reactor_Exceptions_Test and
          Priority_Tasks_Tests. Files changes include run_tests.bat,
          tests.mak, and tests.mdp.

        * tests/Future_Test.cpp (main): Fixed memory leaks in main() and
          in name_i().

        * tests/Thread_Pool_Test.cpp (open): The loop was messed up
          causing memory leaks. I fixed it.

        * ace/UPIPE_Stream.cpp (close): I am not sure why the stream was
          closed with M_DELETE_NONE. This indicates that close() should
          not delete any Tasks. This caused a memory leak as the Tasks in
          the Tail and Head modules were not deleted. I have removed this
          to fix the memory leak.

          Also added a destructor such that mb_last_ is released if it is
          still around. 

Tue May 13 16:48:18 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * ace/Process.cpp: Added implementations to new interfaces
          to ACE_Process_Options::setenv (char *envp[]), and
          ACE_Process_Options::command_line (char *argv[]).

        * apps/JAWS/server/HTTP_Response.cpp: Required changes so that CGI
          processing will work with the new ACE_Process class.

        * apps/JAWS/stress_testing/benchd.cpp: Requried changes due to
          changes in the ACE_Process interface.

Tue May 13 15:22:01 1997  Tim H. Harrison  <harrison@waltz.cs.wustl.edu>

        * ace/Process_Manager.h:  Changed ACE_Process_Manager::start to
          ACE_Process_Manager::spawn.

        * ace/Process.cpp (spawn): The check for a null environment argv
          was incorrect.  Thanks to Nanbor for finding this.

Mon May 12 18:59:39 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-mvs.h: conditionally use ACE_HAS_UCONTEXT_T or
          ACE_LACKS_UCONTEXT_H depending on __COMPILER_VER__.  Thanks to
          Chuck Gehr <gehr@sweng.stortek.com> for this fix.

        * OS.h, OS.cpp (thr_create), Task.h, Thread.h, Thread_Manager.h:
          use ACE_DEFAULT_THREAD_PRIORITY instead of -1, because -1 is a
          valid priority on Win32.  Thanks to Irfan for discovering this
          problem with Priority_Task_Test.

        * ace/Thread_Manager.cpp (wait_grp,wait_task): changed type of loop
          index "i" from size_t to int to avoid signed/unsigned comparison.

Mon May 12 18:41:19 1997  Nanbor Wang  <nw1@cs.wustl.edu>

        * ace/config-freebsd-pthread.h: 
        * ace/config-freebsd.h: Added ACE_LACKS_RWLOCK_T to FreeBSD config
          files.  Thanks to Amancio Hasty <hasty@rah.star-gate.com> for
          noticing this. 

Mon May 12 17:11:50 1997  Tim H. Harrison  <harrison@waltz.cs.wustl.edu>

        * ace/Process.h: Changed ACE_Process::start to
          ACE_Process::spawn.  Added new argv-style methods for
          ACE_Process::setenv and ACE_Process::command_line.  These new
          argv-style methods do not have implementations yet.

Mon May 12 15:27:41 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/config-aix-4.[12].x.h: Added ACE_HAS_EXCEPTIONS to
          the AIX 4.* config files.  Thanks to Chris Lahey for this.

Mon May 12 13:49:54 1997    <irfan@TWOSTEP>

        * ace/Thread_Manager.cpp (wait): We have to make sure that while
          we wait for these threads to exit, we do not have the
          lock. Therefore we make a copy of all interesting entries and
          let go of the lock. We then do the join().

        * ace/Task.cpp (wait): Removed the extra locking in wait(). The
          Thread Manager will handle this correctly.

        * ace/ACE.cpp (register_stdin_handler): Changed the options such
          that the Thread Manager used for the adapter is passed along to
          the method executed by the new thread. We can then notify the
          thread manager when this adapter thread exits.

        * examples/ASX/Event_Server/Event_Server: Changed the way the
          reference count was being kept on the context. Now, the
          reference count starts with zero and every instance and every
          active Task increments it. This works well as Task::close() is
          called one from the module being deleted and from the active
          thread going away.

Mon May 12 11:11:51 1997    <harrison@samba.cs.wustl.edu>

        * ace/Process.*: Removed the old ACE_Process and replaced it with
          what was ACE_ProcessEx.

        * ace/Process_Manager.{i,cpp}:  Updated to use the new ACE_Process
          API.

Mon May 12 08:16:38 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-freebsd*.h: added support for FreeBSD 2.1.7R.
          Thanks to Satoshi Ueno <satoshi.ueno@gs.com> for figuring
          out the differences and to Nanbor Wang <nw1@cs.wustl.edu>
          for updating the config files.

Sun May 11 17:36:59 1997    <harrison@samba.cs.wustl.edu>

        * tests/{Pipe_Test.cpp, Process_Mutex_Test.cpp,
          Time_Service_Test.cpp, Token_Service_Test.cpp}:  Updated these
          files to use the new ACE_Process API.

Sun May 11 14:40:51 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-osf1-4.0.h: put back ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS.

        * ace/ACE_Process.cpp (ACE_Process_Options ctor): reordered
          initializers to match declaration order.

Sat May 10 19:44:28 1997    <harrison@samba.cs.wustl.edu>

        * Process.h: ACE_ProcessEx now works on Solaris and NT.  There
          have been some changes to the API.  ACE_ProcessEx::cl_options
          and ACE_ProcessEx::path have been combined into
          ACE_ProcessEx::command_line.  ACE_ProcessEx::command_line must
          be used to specify path and command-line arguments.  There is
          also a second ACE_ProcessEx::setenv method that allows
          applications to set environment variables in a "VAR=VALUE"
          format.

Sat May 10 10:51:11 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/config-osf1-3.2.h: Added three new flags to the config file
          for OSF/1 3.2:

          #define ACE_LACKS_SETSCHED 
          #define ACE_LACKS_RWLOCK_T
          #define ACE_LACKS_GETPGID

          Thanks to Tom Dobridge <dobridge@persimmon.com> for reporting
          this.

Fri May 09 16:37:48 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-osf1-4.0.h: added DEC_CXX.

        * ace/config-osf1-4.0-g++.h: removed commented-out
          ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS.

          Thanks to Thilo Kielmann <kielmann@informatik.uni-siegen.de> for
          patches for the above two OSF config files.
        
        * ace/Sched_Params.cpp (priority_min): On Solaris (with STHREADS),
          don't return priority of 0 because ::pthread_attr_setschedparam ()
          will refuse to use it (with EINVAL).  So, bump priority of 0 up to 1.

        * tests/Priority_Task_Test.cpp: retry the task activation with
          priority 0 if it fails with non-zero priority.  This lets the
          test run on platforms such as Linux that only let the superuser
          set non-zero priority.

        * ace/ACE_Process.cpp (ACE_Process_Options ctor): reordered
          initializers to match declaration order.

        * examples/Connection/non_blocking/test_lsock_acceptor.cpp: fixed
          typo in template specializations: ACE_LSOCK_ACCEPTOR instead of
          ACE_SOCK_LACCEPTOR.

Fri May  9 13:07:20 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/UNIX_Addr: Changed the return values of all the set()
          methods so that they conform to the signature used by the
          INET_Addrs.

        * examples/Connection/non-blocking: Added two new test programs,
          test_lsock_{connector,acceptor}.cpp that 
        

        * ace/LSOCK_Stream.cpp: Revised the get_remote_addr() method so
          that it uses the underlying ACE_SOCK::get_remote_addr() method
          rather than the get_local_addr() method.  Hopefully, this will
          fix an ACE bug with UNIX domain sockets.  Thanks to Paul Han
          <phan@CCGATE.HAC.COM> for reporting the problem and the fix.

        * include/makeinclude/platform_aix4.2.GNU (LLIBS): Changed
        
          LLIBS = -lC_r -lC -lpthreads -lbsd -ltli_r -ldl -lc_r -lm -lc $(ACELIB)

          to

          LLIBS =  -ltli_r -ldl  $(ACELIB)

          MakeC++SharedLib_r includes all the other libs automatically in
          the search. 

        * apps/Gateway/Gateway/Proxy_Handler.h: Moved the handle_close()
          method into the public section since the Connector now calls it.

        * ace/Containers.cpp: Updated all the operator= methods so
          that they no longer try to return *this.  Thanks to Chris Lahey
          for reporting this.

        * ace/IOStream.h: Replaced __alpha with DIGITAL_UNIX && DEC_CXX.
          Thanks to Thilo for reporting this.

        * build/gcc/tests/Simple_Message_Block_Test.cpp (main): Changed
          the use of ACE_Mutex to ACE_SYNCH_MUTEX so that everything will
          build correctly on non-MT platforms.

        * ace/Timer_{Heap,List}_T.cpp: To ensure backwards compatibility
          with the old "int" return value of Timer_*::schedule() we must
          cast the long value to int before returning it.  Thanks to Thilo
          Kielmann <kielmann@informatik.uni-siegen.de> for reporting this.

        * ace/Acceptor.cpp,
          ace/Connector.cpp:
          If an active or passive connection times out and the Connector
          or Acceptor calls the handle_timeout() method of the
          Svc_Handler, we now keep track of whether the handle_timeout()
          method returns -1.  If so, we call handle_close() on the
          Svc_Handler automatically.  Thanks to Michael Hartman
          <c62nt57@ibx.com> for suggesting this.

        * tests/IOStream_Test.cpp: Fixed this test so that it runs on
          non-MT platforms.

        * ace/Module.cpp: Changed the implementation of the close_i()
          method so that it will wait for all active threads in a Task to
          exit before deleting the task.

        * ace/Task: Added a wait() method on an ACE_Task that will use the
          new ACE_Thread_Manager::wait_task() method to block until all
          threads have shutdown in a Task.

        * ace/Thread_Manager: Finally implemented the wait_task() and
          wait_grp() interfaces on ACE_Thread_Manager.  

        * ace/SOCK_Dgram.cpp: Added a timed recv() operation.  Thanks
          to Hongbo Xu <hxu@mas.co.nz> for contributing this.

        * ace/Timer_Queue_T.cpp: Added #include "ace/Synch.h" to keep the
          DEC C++ compiler happy.  Thanks to James CE Johnson
          <jcej@lads.com> for this.

        * ace/Containers.i (size): Changed <TYPE> to <T> so that this
          compiles on the Alpha.  Thanks to James CE Johnson
          <jcej@lads.com> for this.

        * ace/IOStream.h: Include the std_macros header on the Alpha.
          Thanks to James CE Johnson <jcej@lads.com> for this.

        * include/makeinclude/platform_osf1_4.0.GNU (SOBUILD): Removed
          -lACE from the link line.  Thanks to James CE Johnson
          <jcej@lads.com> for this.

        * tests/Timer_Queue_Test.cpp: Changed all the int timer ids to
          long so that the test will work on DEC ALPHAs.  Thanks to Thilo
          Kielmann <kielmann@informatik.uni-siegen.de> for reporting this.

        * ace/Process: Fixed a number of compile problems for UNIX.

        * ace/Process.h: Changed the methods named stdin/stdout/stderr to
          std_in/std_out/std_err to avoid name clashes with the standard C
          library.

        * ace/OS: Changed the use of ACE_Unbounded_Set to
          ACE_Unbounded_Stack in order to get the appropriate semantics
          for TSS cleanup on NT.

        * ace/Containers: Enhanced the ACE_Unbounded_Stack class so
          that it supports insert()/remove()/find() methods.  These
          rather unorthodox methods are useful for implementing the
          TSS semantics required by OS.cpp.

        * ace/Containers: Revised all the interfaces for the various
          containers so that they all have the same "look and feel."

Fri May  9 00:00:21 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * apps/JAWS/server/HTTP_Request.{h,cpp}: Added a uritopath
          translation method, so that CGI location can be computed as it
          is searched.  Added methods to access the parsed headers.

        * apps/JAWS/server/HTTP_Response.{h,cpp}: Flushed out the
          implementation of cgi_response () method.  If all goes well, it
          should be able to execute a CGI program.  I don't set the IO
          handles to point at the socket handle yet.

        * apps/JAWS/server/README: Updated description of JAWS behavior.

Thu May  8 18:04:14 1997  Irfan Pyarali  <irfan@cs.wustl.edu>

        * ace/Containers: Made the return values of Container methods
          more consistant with other components of ACE (i.e., 0 for
          success, -1 for failure).

        * ace/Containers (ACE_Unbounded_Stack<T>::delete_all_nodes):
          Fixed subtle bug in delete_all_nodes.

        * ace/OS.cpp (ACE_TSS_Cleanup::exit): Changed because of
          return value changes in ACE containers. 

        * Containers: Added size methods to stack containers and
          consolidated friendship between ACE_Unbounded_Stack_Iterator and
          ACE_Unbounded_Stack

        * tests/Message_Block_Test.cpp: I was incorrect about each data
          block having its own lock. Since *many* data blocks can share
          the same lock, for the case of message block chains, we would
          like to optimize locking. 

          Therefore, the first guy in the chain grabs the lock and passes
          it to the continuation chain. When each guy in the chain gets
          it, it compares the passed lock to its own locking strategy. If
          it is the same lock, no need to acquire the lock again. If our
          lock is different, then we do our own locking.          

        * tests/Simple_Message_Block_Test.cpp: This test program is a
          torture test that illustrates how ACE_Message_Block reference
          counting works, how and when locks are used, how memory is
          managed, and how continuation chains of message blocks are
          made. Ideally used with purify :-)

        * tests: Added new test. Following changed:
          Makefile run_tests.bat run_tests.sh tests.mak tests.mdp

Thu May  8 18:04:14 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * include/makeinclude/platform_irix6.2_sgic++.GNU:  Moved SGI C++
          options out of CPPFLAGS into CCFLAGS so that gcc won't emit
          diagnostics during a make depend.

Thu May  8 11:52:41 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/{Task,Thread}.h: Added documentation describing
          thread priority determination to methods where priority
          is an [optional] argument.  Note that if you want to inspect
          the REAL documentation, you should look at the code for
          ACE_OS::thr_create().  But that's convoluted and touchy.

        * ace/Strategies_T.h (ACE_Cached_Connection_Strategy): Added
          documentation for this class.

Thu May 08 00:10:00 1997    <harrison@samba.cs.wustl.edu>

        * ace/Process.*: This is the first pass at the new ACE_Process
          class.  It is now called ACE_ProcessEx.  When it is completely
          ported to Solaris, we'll replace the current ACE_Process with
          ACE_ProcessEx.

        * examples/OS/Process/process.cpp: Added some examples for the
          new ACE_ProcessEx.

Wed May 07 21:58:29 1997    <irfan@TWOSTEP>

        * ace/Message_Block.h: ACE_Data_Block calling delete on the
          ACE_Message_Block was incorrect.  This was a hack to simplify
          the locking issues! However this optimization leaded to
          incorrect code. Therefore I have taken this behavior out. The
          new implementation will lock and unlock multiple times in the
          case when there are message_blocks in the continuation field,
          all of which point to same data block. However, this is a
          strange case that can be optimized later. For now correct code
          is more important.

          Also, the continuation message blocks are only deleted in the
          release() method and not in the destructor. This will ensure
          that if message blocks of the stack are chained together, we
          will not call release on message blocks of the stack.

          Also note that release() should only be called on message blocks
          that have been dynamically allocated. Message blocks of the
          stack will clean up properly when the activation record of the
          method completes. Dynamically allocated messages blocks should
          *never* be chained with message blocks allocated of the stack.
        
        * examples/ASX/Event_Server/Event_Server/Peer_Router.h: Removed
          empty definitions of assignment operator and copy constructor.

        * examples/ASX/Event_Server/Event_Server/event_server.cpp
          (handle_input): Added code here will make sure we actually wait
          for the user to type something. On platforms like Win32,
          handle_input() is called prematurely (even when there is no
          data).

        * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: Changed
          a log message.

Wed May  7 22:55:00 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * JAWS/server/*: Debugging changes!  GET and HEAD both work
          now.  As well as changes to make it compile cleanly on
          VXWORKS, as reported by David.

Wed May 07 16:05:39 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Makefile: added Timer_Wheel to FILES.  Thanks to Thilo
          Kielmann <kielmann@informatik.uni-siegen.de> for reporting this.

        * include/makeinclude/platform_irix6.2_sgic++.GNU: enabled CPPFLAGS
          to instantiate all templates so that gatewayd will build.
          Thanks to Nathan N. Vuong <nvuong@mail08.mitre.org> for reporting
          this problem and Eric Dean Russell <edrusse@somnet.sandia.gov>
          for supplying and the fix.

        * ace/Map_Manager.h: updated comments to indicate that find
          functions return a non-negative integer if the item is found.

        * ace/Map_Manager.cpp (find_i (const EXT_ID &, INT_ID &)): return
          index instead of 0 if the item is found, to be consistent with
          find_i (const EXT_ID &).

        * ace/IOStream.cpp (ACE_Streambuf_T ctor): added initializations of
          eback_saved_ and pbase_saved_ to avoid unitialized memory read
          reports from Purify.

Tue May  6 07:39:25 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Service_Config.cpp (open): Make sure to perform the
          daemonization logic first so that we get a new process created
          before initializing reactors, etc.  Thanks to Adrian Salt
          <acsalt@magi.com> for reporting this.

        * examples/IPC_SAP/SOCK_SAP/CPP-inserver-poll.cpp (main): 
          Changed ACE::INVALID_HANDLE to ACE_INVALID_HANDLE.
          Thanks to Dani Flexer <danif@alice.actcom.co.il> for
          reporting this.

        * tests/Conn_Test.cpp (compare_i): Changed the comparison from
          a1 == a2 to a1 != a2 since this appears to be what is needed.
          We need to improve the comments here!

        * tests/Conn_Test.cpp: Split the definition of the Svc_Handler
          template into its own Conn_Test.h file to work around "features"
          with AIX C++.  Thanks to Chris Lahey for reporting this.

        * ace/Containers.cpp: Fixed a bug in the set() method for
          ACE_Unbounded_Queue.  Again, thank goodness for cs242!

        * ace/Containers.cpp: Fixed a bug in the enqueue_head() logic for
          ACE_Unbounded_Queue.  Thank goodness for cs242 ;-).

        * ace/Containers.cpp: Added a destructor for ACE_Node to keep the
          compilers happy.

Tue May 06 11:31:49 1997  David L. Levine  <levine@cs.wustl.edu>

        * netsvcs/lib/*.cpp: removed break statements after
          ACE_RETURNs to avoid unreachable statement warnings from
          GHS.  

        * ace/OS.cpp (mktime): added time_t cast of -1 (error) return
          to avoid compiler warning.

        * ace/config-vxworks-ghs-1.8.h: added ACE_LACKS_SIGNED_CHAR.

        * ace/Containers.cpp (dequeue_head): fixed typos in variable names.

        * examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp:
          removed #ifdef ACE_HAS_TLI around some template specializations so
          that this subproject will build on platforms non-TLI platforms such
          as Linux.

Tue May  6 17:02:54 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * ace/OS.{h,i}: Added strftime ().  Also, enhanced strcasecmp
          implementation to account for lexicographical ordering for
          mismatches.

        * apps/JAWS/server/Parse_Headers.{h,cpp} (class Headers_Map):
          Changed signature of casting operator to return a pointer
          rather than a reference to a constant pointer, to fix
          anachronism warning Doug found.

        * apps/JAWS/server/HTTP_Config.{h,cpp}: Added class
          HTTP_Config to be a container for HTTP server options
          such as locations of directories, port, etc.

        * apps/JAWS/server/HTTP_Helpers.{h,cpp}: Added code to enhance
          support for CGI scripts: 
          - Added HTTP_decode_string to HTTP_Helper class, to deal
            with percent codes.

        * apps/JAWS/server/HTTP_Request.{h,cpp}: Added code to enhance
          support for CGI scripts: 
          - Added cgi_, cgi_env_, and cgi_args_ data members to
            and corresponding accessors.
          - Added nice accessors to the important data members to
            simplify other parts of the code.
          - Added method to parse URI to determine the name of the CGI
            executable if present.

        * apps/JAWS/server/HTTP_Response.{h,cpp}: Added code to
          enhance support for CGI scripts:
          - Hooks are now present to make the appropriate calls
            to activate a CGI program.

        * apps/JAWS/server/*.{h,cpp}
          Various changes from the ACE mailing list incorporated.
          Cosmetic changes for ACE coding style.

          SGI fixes.

Tue May  6 00:00:54 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/Message_Block.cpp: Added template specialization for
          ACE_Guard<> that prevented ACE from compiling under Linux.

Mon May  5 22:17:15 1997  Sumedh Mungee      <sumedh@cs.wustl.edu>
        
       * apps/JAWS/stress_testing: Removed the usleep definition from
         global.h, it was unused by the program.

Mon May 05 21:01:42 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-linux*.h: added ACE_HAS_STRING_CLASS.  Thanks to
          Luis Lopes <llopes@tick.rcc.Ryerson.CA> for reporting this.

Mon May 05 19:58:16 1997    <irfan@TWOSTEP>

        * ace/ace.{mak,mdp}: Readded IOStream.cpp to the makefile. 

        * ace/Synch_T.h: Added ACE_SYNCH_RECURSIVE_MUTEX.

        * ace/Timer_Queue: Added an extra template parameter to
          Timer_Queues that specifies the type of locking to be used
          inside of the timer queue.

          Also changed the functor callback routines so that they are more
          descriptive compared to operator ().

Mon May  5 21:37:01 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Message_Block: Revised the release() logic for
          ACE_Message_Block and ACE_Data_Block so that we will delete both
          within the same block of code in order to hold the lock.  This
          should prevent nasty race conditions in multi-threaded programs.
          Thanks to Craig Perras <craig.perras@CyberSafe.COM> for
          reporting this problem.

        * ace/Message_Block.cpp: Replaced an explicit acquire()/release()
          of ACE_Lock::locking_strategy_ with a call to an ACE_Guard.

        * ace/Containers.cpp (set): Optimized for the common case where
          we're increasing the size of the set by 1.

        * ace/Containers: Merged the ACE_Set_Node, ACE_Stack_Node, and
          ACE_Set_Node into a single "ACE_Node" class.  This tidies up the
          code quite a bit.

        * ace: Removed the Set.* and Stack.* files and replaced them with
          the Containers.* files.  This file contains the ACE_*Stack,
          ACE_*Queue, and ACE_*Set classes.  If this revised file scheme
          breaks existing code please let me know and I'll provide
          backwards compatibility.

        * ace/Stack: Changed the name of ACE_Unbounded_Queue::enqueue() to
          ACE_Unbounded_Queue::enqueue_tail() and also added
          ACE_Unbounded_Queue::enqueue_head().

        * ace/OS: Changed the names of the parameters of the ACE_OS::mem*
          methods from ACE_OS::mem* (void *s, const void *t) to
          ACE_OS::mem* (void *t, const void *s) since "t" should stand for
          "target" and "s" for "source."  Thanks to Andres Kruse
          <Andres.Kruse@cern.ch> for pointing this out.

        * ace/Stack: Removed the peek() method from ACE_Unbounded_Queue.
          This functionality is now subsumed by the get(..., 0) method.
          If this breaks any existing code please let me know.

        * ace/Stack.h: Moved all the functionality from ACE_Unbounded_Set
          into ACE_Unbounded_Queue.  That's really where this belonged in
          the first place.  Thanks to David Levine for noticing this.

        * ace/Set.h: Moved ACE_Set_Node from the *.cpp file into the *.cpp
          file in anticipation of AIX C++ compiler bugs ;-).

        * examples/ASX/Event_Server/Transceiver/transceiver.cpp:
          Rearranged the location where we register to receive standard
          input so that the socket handle will not be initialized at this
          point.  Thanks to craig perras <craigp@wolfenet.com> for
          reporting this.

        * examples/ASX/Event_Server/Transceiver/transceiver.cpp
          (Event_Transceiver): Make sure to #ifdef around SIGQUIT for
          WIN32 since it lacks this signal.  Thanks to craig perras
          <craigp@wolfenet.com> for reporting this.

        * ace/config-osf1-4.0-g++.h: Removed the ACE_LACKS_SIGNED_CHAR
          since this seems to be compiler specific.  Thanks to Thilo for
          this insight.

        * ace/Strategies_T: Added a number of fixes and enhancements to
          the new Hash_Addr and ACE_Cached_Connect_Strategy classes.

        * ace/Strategies_T.h: Added #include for "Hash_Map_Manager.h".
          Thanks to Amos Shapira <amos@dsi.co.il> for reporting this.

        * ace/config-hpux-10.*.h: Applied a number of patches courtesy of
          Carlos O'Ryan.

        * ace/Dump.cpp: Changed a cast from

          delete (ACE_Dumpable_Ptr *) this->dumper_;

          to

          delete (ACE_Dumpable *) this->dumper_;

          This fixes a potential bug.  Thanks to Carlos O'Ryan for this
          bug report.

        * ace/DEV_IO.h,
        * ace/SPIPE_Stream.h: Removed the = 0 default value for one send()
          method to avoid ambiguity with the other send() method.  Thanks
          to Carlos O'Ryan for this bug report.

        * ace/Map_Manager.cpp (advance): Removed a cast to size_t since
          that is always true.  Thanks to David Levine for pointing this
          out.

        * ace/XtReactor: Moved the remove_handler_i() and
          register_handler_i() methods into the protected portion
          of the class.  Since these should never be called by the
          client I've moved them into protected portion to ensure this
          is the case. 

        * ace/XtReactor: Changed the implementation of the XtReactor to
          use long for dealing with timers.  Thanks to Stuart Powell
          <stuartp@in.ot.com.au> for reporting this.

Mon May 5 17:16:41 1997  Carlos O'Ryan  <coryan@mat.puc.cl>

        * ace/config-hpux-10.x.h, config-hpux-10.x-nothread.h: 
          Some patches are needed to compile ACE under HP-UX (using HP/C++),
          I documented those patches.
 
Mon May 05 11:50:39 1997  David L. Levine  <levine@cs.wustl.edu>

        * netsvcs/lib/Server_Logging_Handler.cpp: fixed ACE_Svc_Handler
          specializations, yet again, for Linux w/LXPthreads.  Thanks to
          Luis Lopes <llopes@tick.rcc.Ryerson.CA> for reporting this
          problem with sufficient detail for us to track it down.

        * ace/Stack.* (ACE_Unbounded_Queue):

          1) made peek () const.
          2) added another peek (u_int index = 0) function that can peek
             at any queue item, not just the first.  It returns a pointer
             to the item (or 0 if not found), to avoid copying.
          3) changed return type of size () from int to size_t.
          4) inlined size ().

        * ace/Strategies_T.cpp (connect_svc_handler, operator==):
          added return type.

        * netsvcs/lib/Server_Logging_Handler.cpp: fixed template
          specializations for platforms that have neither THREADS nor
          TLI.  Thanks to Nanbor Wang <nw1@cs.wustl.edu> for reporting this.

Sun May  4 12:34:09 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.cpp: If ACE_HAS_THREADS isn't defined then we'll just
          use mktime() without the locking.

        * ace/Set: Removed the get() methods from the ACE_Fixed_Set and
          ACE_Bounded_Set since they don't make much sense on these
          abstractions.

        * ace/Set: Changed the new "find" method to be called "get" to
          correspond to the new "set" method I'm adding.

        * ace/SString.cpp: Added a operator << for ACE_CString in 
          order to print it with iostreams.

        * ace/Set.cpp: Added a reset method to the ACE_Unbounded_Set to
          remove all the nodes without completely destroying the set.

        * ace/SString: Added friend operator+ to both ACE_CString and
          ACE_WString in order to provide a concatenation operator.

        * ace/SString: Added a compare() method to all the ACE String
          classes.  This behaves just like the Standard C library strcmp()
          function.

        * ace/Message_Queue.i: Oddly, there were a bunch of methods
          defined in this *.i file that didn't have ACE_INLINE in front of
          them.  I'm surprised this didn't give compile errors on some
          platforms.  I've fixed this by moving these methods into the
          *.cpp file.

        * ace/Stream,
          ace/Service_Repository,
          ace/Reactor,
          ace/Message_Queue,
          ace/Map_Manager,
          ace/Malloc_T,
          ace/Hash_Map_Manager,
          ace/Set: Added a done() method on all the iterators so that
          we can check within the iteration itself to see if there are any
          remaining elements.  In addition, updated the return value of
          advance() on all iterators so that it returns 1 if we're not
          done and 0 if we're done.

Sun May 04 07:22:49 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Timer_Heap_T.cpp: changed some more int declarations to longs.

Sat May  3 17:38:19 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * Changed all uses of Reactor::{scheduler_timer,cancel}() and
          Timer_{Queue,List,Heap,Wheel}::{schedule,cancel}() to use 
          long rather than int.  This is important since it ensures that
          we can make the Timing Wheels trick of casting the
          Timer_Node * to long work correctly on machines that have 64
          bit pointers, 64 bit longs, and 32 bit ints (e.g,. DEC
          ALPHA).  Thanks to Thilo Kielmann
          <kielmann@informatik.uni-siegen.de> for pointing this out,
          even though he finds this solution distasteful ;-).

        * netsvcs/lib/TS_Clerk_Handler.cpp (initiate_connection): I
          believe there was also a bug here -- if schedule_timer() returns
          0 that's not an error!

        * apps/Gateway/Gateway/Proxy_Handler_Connector.cpp
          (initiate_connection): I believe there was a bug here -- if
          schedule_timer() returns 0 that's not an error!

        * tests/IOStream_Test.cpp: Added some minor changes for DEC UNIX.
          Thanks to James CE Johnson <jjohnson@lads.com> for reporting
          this.

        * ace/IOStream: Added a number of minor changes for DEC UNIX.
          Thanks to James CE Johnson <jjohnson@lads.com> for reporting
          this.

        * ace/config-osf1-4.0.h: Added
          ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS to the config.h file.
          Thanks to James CE Johnson <jjohnson@lads.com> for reporting
          this.

        * ace/SString: Made the ace_string_null_string_ a static data
          member rather than an external constant.  This should control
          the name space a bit better.

        * ace/SString.cpp: Fixed the ACE_CString::operator += so that it
          won't screw up if this->rep_ initially points to the
          ACE_String_null_string_.

        * examples/Misc: Added a new test_set.cpp program that exercises
          the ACE_*_Set classes.

Sat May 03 06:56:10 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Map_Manager.cpp (dtor): removed void return (typo).

        * ace/Set.cpp (ACE_Fixed_Set<T>::operator =): typo: fs instead of bs.

        * ace/Set.cpp (ACE_Fixed_Set<T, SIZE>::find): typo: index instead of i.

        * ace/IOStream.cpp: fixed typo: "#if defined" instead of just "#if".

        * tests/Conn_Test.cpp,
          netsvcs/lib/{Client_Logging_Handler,TS_Clerk_Handler}.cpp,
          netsvcs/clients/Tokens/manual/manual.cpp,
          apps/Gateway/Gateway/Event_Channel.cpp,:
          apps/JAWS/client/Blob.cpp,
          examples/ASX/Event_Server/Event_Server/Peer_Router.cpp,
          examples/ASX/Event_Server/Transceiver/transceiver.cpp,
          examples/ASX/UPIPE_Event_Server/{Consumer,Supplier}_Router.cpp,
          examples/Connection/misc/test_upipe.cpp,
          examples/Connection/non_blocking/test_*_connector.cpp: added
          ACE_Map_Entry template specialization.  It's needed now that the
          destructor is explicit.

Fri May  2 14:57:56 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Map_Manager.cpp: Added a no-op destructor to ACE_Map_Entry
          just to keep some compilers happy.  Thanks to Chuck Gehr for
          reporting this.

        * ace/config-osf1-4.0.h: Added 
        
          #define ACE_LACKS_IOSTREAM_FX
          #define ACE_LACKS_LINEBUFFERED_STREAMBUF
          #define ACE_LACKS_SIGNED_CHAR

          Thanks to James CE Johnson <jjohnson@lads.com> for reporting
          this.

        * ace/Timer_{Wheel,Heap,List}_T.h: Fixed a typo in all these
          classes that was failing to put the keyword "class" after
          "friend."  Also, replaced the use of the typedef with the
          expanded name of the class to work around problems with DEC
          C++.  Thanks to James CE Johnson <jjohnson@lads.com> for
          reporting this. 

        * ace/Set: Added a find() method that will return the "ith"
          element in the set.

        * ace/Set: Added copy constructors and assignment operators to all
          the ACE_*_Set classes.

        * ace/Set.cpp: Changed the implementation of ACE_Unbounded_Set to
          use a dummy node and a circular list.  This improves performance
          and also makes it possible to implement "queue" semantics for
          inserting at the tail of the set.

        * ace/config-osf1-4.0.h: Added the ACE_HAS_STRING_CLASS macro.
          Thanks to James CE Johnson <jcej@lads.com> for this.

        * ace/IOStream: Added the ACE_HAS_STRING_CLASS macro to
          replace the nasty #ifdefs we had previously.  Thanks to
          James CE Johnson <jcej@lads.com> for this.

        * ace/config*.g++: Added ACE_HAS_STRING_CLASS for all the GNU 
          compilers and Win32.

        * ace/config-mvs.h: Added a new version that contains support for
          IBM OS/390 r2.  Thanks to Chuck Gehr for this.

Fri May 02 08:14:30 1997  David L. Levine  <levine@cs.wustl.edu>

        * examples/ASX/Event_Server/Transceiver/transceiver.cpp: removed
          specializations of ACE Guards because they're in libGateway.
          Thanks to Joey Zhu <joey.zhu@wcom.com> for reporting this problem.

        * examples/ASX/Event_Server/Transceiver/{Makefile,transceiver.cpp}:
          added template specializations to transceiver.cpp so that it no
          longer needs to be linked with libGateway.

        * examples/ASX/Event_Server/Event_Server/{Makefile,Peer_Router.cpp}:
          added template specialization to Peer_Router.cpp so that event_server
          no longer needs to be linked with libGateway.

        Thanks to Joey Zhu <joey.zhu@wcom.com> for reporting the above
        link problems.

        * apps/Gateway/Peer/{Makefile,Peer.cpp}: added template
          specialization to Peer.cpp so that peerd no longer needs to
          be linked with libGateway.

        * Log_Msg.cpp (VxWorks only): fixed used of ::taskDeleteHookAdd (it
          should only be called once for all Log_Msg instances) and added call
          to ::taskDeleteHookDelete to clean up when the last task exits.
          Thanks to Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com> for
          reporting this.

        * tests/Conn_Test.cpp: changed some fprintf print specifiers to avoid
          g++ warnings about printing pointer values.

Thu May 01 00:05:59 1997    <irfan@TWOSTEP>

        * tests/Time_Service_Test.cpp (main): Made sure that the backing
          store is not there at the start of the program. We need to make
          sure because this test kills the Time Clerk and on some
          platforms the Clerk is not allowed to do a graceful shutdown. By
          cleaning the backing store here, we are sure that we get a fresh
          start and no garbage data from a possible aborted run. 

          The old code deleting the backing store at the end of the test
          is still there but does not work on Win32 as unlink fails with
          ERROR_ACCESS_DENIED. I am not sure why this is happening!  For
          now the unlink at the start of the program will do.

          Also added a wait for the clerk before deleting the backing
          store. This way we are sure that we do not delete the backing
          store before the clerk is done with it.

        * netsvcs/lib/TS_Clerk_Handler.cpp: Fixed an obscure bug with
          ACE_TS_Clerk_Processor. ACE_TS_Clerk_Processor (which is an
          ACE_Connector) and all its pending connection objects are still
          registered with the Reactor when the process exits and the
          Service_Object is deleted. After this the destructor of the
          Reactor then calls handle_close on ACE_TS_Clerk_Processor
          (which does not exist anymore), causing a seg fault. The
          solution is to call ACE_Connector::fini from
          ACE_TS_Clerk_Processor::fini. ACE_Connector::fini will
          unregister ACE_TS_Clerk_Processor and all pending connects from
          the Reactor.

Wed Apr 30 17:47:11 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.i (getpwnam_r): Changed the expression to check if
          getpwnam_r() returns -1 for AIX.  Thanks to Chris Lahey for
          this.

        * ace/Timer_Wheel_T.h: changed

          // = Don't allow these operations for now.
          ACE_Timer_Wheel_T (const ACE_Timer_Wheel_T &);
          void operator= (const ACE_Timer_Wheel_T &);
 
          to:
 
          // = Don't allow these operations for now.
          ACE_Timer_Wheel_T (const ACE_Timer_Wheel_T<TYPE, FUNCTOR> &);
          void operator= (const ACE_Timer_Wheel_T<TYPE, FUNCTOR> &);

          Thanks to Chuck Gehr for reporting this.

        * ace/OS.cpp: Made mktime() thread-safe.  If any platforms support
          multi-thread safe versions of mktime() please let me know so we
          can set the ACE_HAS_MT_SAFE_MKTIME macro for that config file.

        * ace/OS.i: Added a new special case for getpwnam_r() on AIX.
          Thanks to Chris Lahey for reporting this.

Wed Apr 30 16:01:04 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * ace/OS.i, ace/OS.h: added mktime().

Wed Apr 30 14:17:34 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-vxworks*.h: added ACE_LACKS_PWD_FUNCTIONS.  Thanks
          to Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com> for reporting
          this.

        * ace/OS.i: cleaned up ACE_LACKS_PWD_FUNCTIONS comments a bit.

        * ace/Array.{h,i}: added const operator [].

        * ace/Array.cpp (ctors): reordered initializers to match declaration
          order.

        * netsvcs/lib/Server_Logging_Handler.cpp: protect against multiple
          inclusion.  Thanks to Kevin Martindale
          <kevin_martindale@stortek.com> for reporting this problem.

Wed Apr 30 08:42:55 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace: Added a new generic Array class, which we'll use until
          STL becomes more widely portable.

        * ace: Added a new macro ACE_LACKS_GETPGID to clean up the code
          in ACE_OS::getpgid().

        * ace: Added new config*.h files and platform*.GNU files for
          FreeBSD.  Thanks to Nanbor Wang <nw1@cs.wustl.edu> for these.

Wed Apr 30 07:44:36 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-osf1-4.0*.h: removed ACE_HAS_SIGWAIT.

        * ace/OS.{h,i}: applied Thilo's patch for sigwait on Digital
          Unix 4.0, which defines sigwait as a macro.  Thanks to
          Thilo Kielmann <kielmann@informatik.uni-siegen.de> for
          this and the above config file patches.

        * ace/IOStream.{h,cpp}: James CE Johnson <jcej@lads.com> updated
          the IOStream class; see comments in IOStream.h.

        * examples/Logger/client/logging_app.cpp (main),
          performance-tests/Misc/test_naming.cpp (*): replaced sprintf
          with ACE_OS::sprintf.  Thanks to Thilo Kielmann
          <kielmann@informatik.uni-siegen.de> for reporting these.

Tue Apr 29 20:03:38 1997    <sumedh@cs.wustl.edu>

        * apps/JAWS/stress_testing/http_tester.cpp : Removed usage
          of pow (), and changed method of calculating throughput/latency
          to use straight multiplication instead of pow (). Updated
          Makefile to not link -lm.

Tue Apr 29 19:57:52 1997    <irfan@TWOSTEP>

        * config-win32-common.h (ACE_HAS_TEMPLATE_SPECIALIZATION): Win32
          supports this option. Added to config file.

        * ace: Removed tracing for the following to make things work with
          tracing on:
          
          ACE::timestamp
          ACE_FIFO_Send_Msg::send
          ACE_SPIPE_Stream::send
          ACE_Sig_Guard::ACE_Sig_Guard
          ACE_Sig_Guard::~ACE_Sig_Guard

        * netsvcs/servers/main.cpp (main): Added special code for Win32
          such that only SIGINT is being registered with the Signal
          Handler. SIGQUIT is not supported on Win32.

        * netsvcs/lib/Token_Handler.cpp (init): Removed the registration
          of the Acceptor for SIGINTs.

        * netsvcs/lib/TS_Server_Handler.cpp (init): Same as above.

        * netsvcs/lib/Client_Logging_Handler.cpp (open): Removed the
          registration of SIGPIPE for Win32. Win32 does not support
          SIGPIPE.

        * tests/Process_Strategy_Test.cpp (server): The new thread must
          become owner before it can call Reactor::handle_events. Also
          fixed #define typo.

        * ace/OS.cpp (socket_fini): Remove the ACE error message as the IO
          Stream objects are already gone by this point in the program.

        * examples/Registry/Registry.mak: Replaced the old makefiles with
          this one. Also added _AFXDLL as a preprocessor define, forcing
          the correct inclusion of header files that give a consistent
          definition of HKEY. This is a hack till we have a better
          solution.

        * ace/Event_Handler: Removed the old Proactor callback methods. 

Tue Apr 29 17:39:40 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/config-mvs.h: Added #define ACE_LACKS_LINEBUFFERED_STREAMBUF
          for MVS.  Thanks to Chuck Gehr <gehr@sweng.stortek.com> for
          reporting this.

        * ace: Commented out ACE_TRACE calls in constructors in
          several ACE classes in order to avoid problems with circular
          initialization dependencies related to mutexes that are
          breaking code on WinNT when ACE_NTRACE is set to 0.  Thanks
          to Lothar Hermann <hermann@csaserv.med.siemens.de> for
          reporting these. 

        * ace/Reactor.cpp: It looks as if Windows NT isn't returning
          the number of bytes requested by a WinSock recv() used in
          the ACE_Reactor::notify() in some situations.  This is
          causing problems for test programs under heavy load.  The
          fix appears to be to add an additional ACE::recv() to obtain
          the remaining bytes.  Thanks to Karlheinz for reporting this
          and to Irfan for helping to fix it.

        * ace/OS.i: Fixed a very subtle bug with ACE_OS::cond_wait() and
          ACE_OS::cond_signal() that only manifests itself when
          ACE_HAS_SIGNAL_OBJECT_AND_WAIT is enabled (which isn't the
          default).  The problem stemmed from the fact that we were
          assuming that if we used condition variables it implied that the
          external mutex had USYNC_PROCESS scope.  In fact, the external
          mutexes typically have USYNC_THREAD scope, so
          SignalObjectAndWait() was hanging indefinitely.  Fortunately,
          the fix was easy -- just add a run-time check for the type of
          the external mutex and take the appropriate action.  Thanks to
          Irfan for noticing this.

        * tests/Reader_Writer_Test.cpp: Added a parse_args() function that
          allows us to override the default number of reader/writer
          threads + the number of iterations.

        * ace/OS: Added patches for Digital UNIX to handle the
          getpwnam_r() name.  Thanks to Thilo Kielmann
          <kielmann@informatik.uni-siegen.de> for these patches.

Tue Apr 29 14:27:19 1997    <harrison@samba.cs.wustl.edu>

        * OS.h: Added ACE_HAS_SVC_DLL.  If you write a library and
          want it to use ACE_Svc_Export, this will cause those macros
          to build dlls.  If you want your ACE service to be a static
          library, comment out this line.  As far as I know, the only
          reason to have a library be an ACE "service" is to leverage
          the ACE_Svc_Export macros.  It's just as easy to define your
          own export macros.

Tue Apr 29 07:25:25 1997  David L. Levine  <levine@cs.wustl.edu>

        * apps/JAWS/server/HTTP_Request.h (HTTP_Request): added destructor
          declaration.

        * apps/JAWS/server/Parse_Headers.cpp (parse_header_line): assign local
          "value" to value_ field of map_[header].

        * apps/JAWS/server/HTTP_Request.cpp (HTTP_fix_path): commented this
          static function out because it's not used, and g++ warns about that.

        * apps/JAWS: added CVS header to all .h, .i, and .cpp files.

Tue Apr 29 00:33:46 1997    <irfan@TWOSTEP>

        * examples/Reactor/Misc/notification.cpp: Add this test to the
          Win32 makefile.

        * ace: Removed config-win32-msvc2.0.h,  config-win32-msvc4.0.h
          config-win32-msvc4.x.h, and config-winnt-4.0-msvc.h from the
          repository. These files have been replaced by config-win32.h
          and config-win32-common.h.

        * IOStream_Test.cpp (main): Added return 0 at the end of main().

        * examples/Reactor/Proactor/test_proactor.mak: Added wsock32.lib
          to the link line. I am not sure why we have to do this again
          since ace.lib already includes it. Without this library in the
          link line, GetAcceptExSockaddr is not defined. Go figure!

        * apps/JAWS/server/jaws.mak: Same as above.

        * ace/ace.{mak,mdp}: Fixed the generation of the release version
          of ace.dll such that wsock32.lib is automatically included.

Tue Apr 29 00:16:27 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * JAWS: Changes to support CGI scripts

          Changed the following files --
          HTTP_Handler.cpp HTTP_Handler.h HTTP_Helpers.cpp
          HTTP_Helpers.h HTTP_Request.cpp HTTP_Request.h IO.cpp IO.h

          Added the following files --
          HTTP_Response.cpp HTTP_Response.h Parse_Headers.cpp
          Parse_Headers.h

          Removed the file --
          JXH_String.h

        * JAWS/stress_testing: Changed the Makefile to link in the math
          library (-lm).

        * ace/OS.h and ace/OS.i: Added support for memmove().

Mon Apr 28 21:35:35 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/IOStream.h: Added a new macro called
          ACE_LACKS_IOSTREAM_SETGET, which works around bugs with SGI C++
          on IRIX 6.2.  Thanks to Torbjorn Lindgren <tl@funcom.com> for
          reporting this.

        * ace/Timer_List_T.h: Replaced the use of 
          ITERATOR with ACE_Timer_Queue_Iterator_T<TYPE, FUNCTOR> to
          work around problems with SGI C++.  Thanks to 
          Torbjorn Lindgren <tl@funcom.com> for reporting this.

        * ace/Timer_List_T.cpp: Removed the use of NODE * and replaced it
          with ACE_Timer_Node_T<TYPE, FUNCTOR> in order to work around
          bugs with certain C++ compilers (i.e., SGI).  Thanks to Torbjorn
          Lindgren <tl@funcom.com> for reporting this.

        * tests/Conn_Test.cpp: Removed some extraneous template
          specializations.  Thanks to Nanbor Wang <nw1@cs.wustl.edu> for
          reporting these.

        * apps/JAWS/client/Blob.cpp: Rearranged some of the template
          specializations in the hope of fixing a linker problem with
          SunC++ 4.2.

        * ace/config-irix-6.2*.h.  It appears that SGI IRIX 6.2 supports
          pread() and pwrite() so I enabled the ACE_HAS_P_READ_WRITE macro
          in the IRIX 6.2 config file.

        * ace/OS.cpp: Implemented ACE_OS::pread() and ACE_OS::pwrite() for
          systems that lack this feature.  The implementation uses the new
          ACE_Thread_Mutex monitor lock in order to ensure atomicity
          between the lseek() and the read()/write().

        * ace/OS.cpp: Finally broke down and added a ACE_Thread_Mutex
          monitor lock to the ACE_OS implementation file.  This is useful
          for situations where we need to serialize certain ACE_OS
          emulation calls (e.g., ACE_OS::{pwrite,pread}).

Mon Apr 28 15:42:48 1997  David L. Levine  <levine@cs.wustl.edu>

        * apps/JAWS/client/blobby.cpp: updated template specializations.

        * apps/JAWS/stress_testing/global.h: removed #includes of system
          headers because ace/OS.h takes care of them.  They were causing
          warnings with g++ (because they were #included before OS.h).

        * examples/ASX/UPIPE_Event_Server/Supplier_Router.cpp: fixed
          typos in template specializations.

        * tests/Conn_Test.cpp,Message_{Block,Queue}_Test.cpp,
          Process_Strategy_Test.cpp: fixed template specializations
          for platforms without threads.  Thanks to Nanbor Wang
          <nw1@cs.wustl.edu> for pointing out this problem.

        * ace/Connector.h: use ACE_SYNCH_RW_MUTEX in Map typedefs
          instead of old ACE_RW_Mutex (which should have been
          ACE_Thread_RW_Mutex) and ACE_Null_Mutex (depending on
          whether the platform has threads). 

        * ace/Service_Record.cpp: added ACE_NULL_SYNCH template
          specializations with threads, because they're still needed even
          with threads.  This way, individual programs don't have to
          specialize these.

        * ace/Task.cpp: added ACE_TSS<ACE_Task_Exit> and
          ACE_TSS<ACE_Dynamic> template specializations, if the platform
          has threads and TSS.  This way, individual programs don't have
          to specialize them.

        * apps/Gateway/Gateway/Event_Channel.cpp,
          Proxy_Handler{,_Connector}.cpp,apps/JAWS/server/HTTP_Server.cpp,
          examples/ASX/Event_Server/Transceiver/transceiver.cpp,
          examples/ASX/UPIPE_Event_Server/Consumer_Router.cpp,
          examples/Connection/blocking/SPIPE-connector.cpp,
          examples/Connection/misc/{Connection_Handler,test_upipe}.cpp,
          examples/Connection/non_blocking/test_*.cpp,
          examples/IOStream/server/iostream_server.cpp,
          examples/Logger/Acceptor-server/server_loggerd.cpp,
          examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp,
          netsvcs/lib/Client_Logging_Handler.cpp,
          netsvcs/lib/TS_{Clerk,Server}_Handler.cpp:
          removed template instantiations that are now in
          ace/Service_Record.cpp and ace/Task.cpp.  This should help
          on platforms without threads.

        * examples/ASX/UPIPE_Event_Server/Supplier_Router.cpp: fixed
          typos in template specializations.

        * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: protected
          the ACE_*Guard template instantiations with #ifdef ACE_HAS_THREADS.

        * examples/ASX/Event_Server/Transceiver/transceiver.cpp: protected
          the ACE_*Guard template instantiations with #ifdef ACE_HAS_THREADS.

        * apps/JAWS/stress_testing/benchd.cpp (serve): added return -1 if
          the strcmp () fails so that the function always returns a value.

Mon Apr 28 18:53:58 1997  Darrell Brunsch <brunsch@cs.wustl.edu>

        * ace/OS.h: Added ACE_DEFAULT_TIMER_WHEEL_SIZE and 
          ACE_DEFAULT_TIMER_WHEEL_RESOLUTION constants.
        
        * ace/Timer_Wheel_T.h: switched to use these constants
          
        * tests/Timer_Queue_Test.cpp: switched to use these constants

        * ace/Timer_Wheel: added a new strategy for Timer Queues, one 
          based on a hash table of ordered lists.  
                
          These files were added:
        
          - ace/Timer_Wheel.h
          - ace/Timer_Wheel_T.h
          - ace/Timer_Wheel_T.cpp
        
          These files were also changed to accomodate Timer Wheel
          
          - ace/Timer_Queue.cpp 
          - ace/Timer_Queue_T.h
          - ace/Timer_Queue_T.cpp
          - tests/Timer_Queue_Test.cpp 

Mon Apr 28 17:32:04 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: Added
          template specializations.

        * examples/ASX/Event_Server/Transceiver/transceiver.cpp: Added
          template specializations.

        * ace/OS.cpp (thr_create): Hopefully resolved tension
          btw. priority determination algorithms for IRIX, LinuxThreads, and
          DEC UNIX 4.0.  Thanks to Thilo for information that lead to this.

Mon Apr 28 00:25:17 1997    <irfan@TWOSTEP>

        * apps/JAWS/client: Removed ACE_Export macro from class
          declarations. Fixed buffer size bug in
          ACE_Blob_Reader::receive_reply ().

Sun Apr 27 22:22:14 1997    <irfan@TWOSTEP>

        * ace/Proactor: The Proactor can now be registered with ReactorEx
          and both of them can be run from ReactorEx's event loop. Added a
          flag to Proactor's constructor that indicates whether the
          Proactor will be used in conjunction with ReactorEx event
          loop. Only if this flag is set will the event in the Proactor be
          used by the Asynch IO components. This will help with
          performance.

        * examples/Reactor/Proactor/test_multiple_loops.cpp: Added a new
          test that shows the integration of the event loops of Proactor
          and ReactorEx.

        * ace/Asynch_IO: Added an ACE_EVENT parameter to the constructors
          of classes that inherit from the OVERLAPPED structure. This way
          the Proactor's event_ can be set in the OVERLAPPED structure.

          Also changed the open methods on the Asynch IO classes to take a
          Proactor as an extra parameter.
        
          Changed ACE_Handler's handle_timeout() to handle_time_out() in
          ACE_Handler. This is temporary till we decide on the argument
          about mixing the interface of ACE_Event_Handler and
          ACE_Handler. This change allows user to inherit from ACE_Handler
          and ACE_Event_Handler and use the different handle_timeout()
          method, one of which returns void and the other return an int.

        * examples/Reactor/Proactor/test_timeout.cpp: This file got
          affected by the above change.

Sun Apr 27 17:44:28 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/OS.h: Added a new #define called ACE_DEFAULT_HTTP_SERVER_PORT.
          Naturally, this defaults to 80...

        * apps/JAWS/client/blobby.cpp: Cleaned up the blobby example so
          that it conforms more closely to the ACE style guide.

        * examples/IPC_SAP/SOCK_SAP/CPP-in{server,client}.cpp: Took out
          the VxWorks-specific #ifdefs.  I believe this is fixed in ACE_OS
          now.  If not, the burden of proof is on the VxWorks testers to
          prove me wrong ;-).

        * ace/Synch_T.h: Added a new macro ACE_SYNCH_RW_MUTEX to
          complement the existing ACE_SYNCH_MUTEX and ACE_SYNCH_CONDITION
          macros.  This will clean up lots of code in various test
          programs.

        * ace/Synch_T.h: Added two new macros, ACE_SYNCH_MUTEX and
          ACE_SYNCH_CONDITION.  These default to ACE_MT_SYNCH::MUTEX and
          ACE_MT_SYNCH::MUTEX if template typedefs are supported and
          ACE_HAS_THREADS is enabled.  If template typedefs *aren't*
          supported but ACE_HAS_THREADS is enabled these macros turn into
          ACE_Thread_Mutex and ACE_Thread_Condition.  Finally, if
          ACE_HAS_THREADS is disabled these macros turn into
          ACE_Null_Mutex and ACE_Null_Condition.  These macros make it
          possible to write code that is more portable across platforms
          and configurations.  Thanks to Carlos O'Ryan for this
          suggestion.

        * ace/OS.h: Replaced all uses of ACE_SYNCH_MUTEX and
          ACE_SYNCH_CONDITION with ACE_SYNCH_MUTEX_T and
          ACE_SYNCH_CONDITION_T since (1) this usage relates to templates
          and (2) it frees up the namespace for the new ACE_SYNCH_MUTEX
          and ACE_SYNCH_CONDITION macros.

        * ace/Timer_Queue.cpp: Added yet more template specializations for
          the benefit of GCC (ugh).

        * ace/Timer_Wheel_T.cpp: Had to revise things just a bit to
          compile with GCC and it's lame template mechanism.  This
          required changing NODE * to ACE_Timer_Node_T<TYPE, FUNCTOR> * in
          several method definitions.

        * apps/JAWS/server/HTTP_Server.h: Changed the use of ACE_WIN32 to
          ACE_HAS_THREAD_SAFE_ACCEPT since this is a more precise way to
          determine if the platform allows multiple threads to call
          accept() on the same port.  If other platforms support this
          feature please make sure to add it to their config*.h files.

        * ace/config-win32-common.h: Defined ACE_HAS_THREAD_SAFE_ACCEPT,
          since Win32 allows multiple threads to call accept() on the same
          port.

        * examples/ASX/UPIPE_Event_Server/Supplier_Router.cpp: The mutex
          should be ACE_RW_Mutex, not ACE_Null_Mutex...

Sun Apr 27 18:13:24 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/Proactor.h: Added Timer_Wheel support.

Sun Apr 27 18:13:24 1997  Sumedh Mungee <sumedh@cs.wustl.edu>

        * apps/JAWS/client: Removed blobby.h, and replaced it with
          blobby_options.{h,cpp}.

        * apps/JAWS/stress-testing: Removed unused argument warnings
          etc.

Sun Apr 27 07:41:44 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Timer_Queue.cpp: added #includes for template specializations,
          and removed some unused specializations.

        * ace/Timer_Wheel_T.cpp: added newline at end of file.

        * ace/Timer_Wheel_T.cpp (ACE_Timer_Wheel_T ctor): reordered
          initializers to match declaration order.

        * ace/Log_Msg.cpp (log): added support for indenting output according
          to the current nesting level by adding a new format specifier, I,
          which indents the output according to the current trace_depth_.
          If a width is also specified it is taken as multiplier (so that
          the indentation is n*trace_depth_).  Thanks to Matthias Kerkhoff
          <make@cs.tu-berlin.de> for providing the code for this feature!

        * examples/Reactor/Misc/test_timer_queue.cpp: fixed typos in
          #includes, and added #include of ace/Timer_Heap.h.

Sat Apr 26 17:19:56 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/Timer_Queue.cpp: The correct Timer_Queue.cpp file was not
          checked in. Also the necessary #include was missing.
        
        * ace/Proactor.h: Proactor need all three Timer include files.

        * ace/ace.{mdp,mak}: Updated for changes to Timer files.

        * ace: Updated the following files to include /**/ before an
          include file directive: OS.h, config-win32-common.h,
          bstring.h. Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de>
          for reporting this.

Sat Apr 26 13:41:15 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/config-sco-5.0.0-mit-pthread.h: Added
          ACE_LACKS_PTHREAD_CANCEL.  Thanks to Arturo Montes
          <mitosys@colomsat.net.co> for reporting this.

        * ace: Came up with a scheme that allowed us to remove the
          ace/Timers.{h,i,cpp} files by adding
          ACE_Timer_{Queue,Heap,List}_T.{h,i,cpp} files instead.  Thus, no
          existing code should break.

Fri Apr 25 17:17:06 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/OS.cpp (thr_create): Fixed the fix from Thilo so that it
          compiled properly on Linux.  Hopefully I didn't break his, and I
          should have detected the problem earlier.  Mea culpa.

Fri Apr 25 12:45:23 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.h: Added a new macro called ACE_HAS_SIG_MACROS for the
          case where the frigging OS defines things like sigismember and
          sigfillset as macros (ugh).

        * ace/FILE_IO.h: Removed a trailing default initializer from the
          send() method since it was ambiguous.  Thanks to Carlos O'Ryan
          for reporting this bug.

        * ace/OS.i (select): Unfortunately the (operator timeval*) defined
          for ACE_Time_Value was not used in ACE_OS::select (int width,
          fd_set *rfds, fd_set *wfds, fd_set *efds, const ACE_Time_Value
          *timeout) because the operator cannot be applied for a
          ACE_Time_Value*.  Therefore, I fixed this as follows:

          ACE_SOCKCALL_RETURN (::select (width, 
                                 (ACE_FD_SET_TYPE *) rfds, 
                                 (ACE_FD_SET_TYPE *) wfds, 
                                 (ACE_FD_SET_TYPE *) efds, 
                                 timeout == 0 ? 0 : (timeval *) *timeout) , int, -1);

          Thanks to Carlos O'Ryan for reporting this bug.

        * ace: Applied a slew of patches from Carlos O'Ryan in order to
          get ACE to compile on HP/UX 10.x with the aCC compiler.

        * ace/Shared_Memory_MM: Export the filename in
          ACE_Shared_Memory_MM class in order to aid debugging.  Thanks to
          Ashish Singhai <singhai@delirius.cs.uiuc.edu> for reporting
          this.

Fri Apr 25 14:58:38 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/Timers: Updated the following files to make it compile on
          g++. The following files were updated:

          Proactor.cpp Timer_Heap.cpp Timer_List.cpp Timer_Queue.cpp
          Timers.cpp

Thu Apr 24 21:13:51 1997    <irfan@TWOSTEP>

        * ace/Timer_Queue: Decoupled the Timer Queue from
          ACE_Event_Handler and the callback routines in the handler
          (handle_timeout and handle_close). The new Timer Queue is
          parameterized by the type of data to store and a FUNCTOR on
          which methods are invoked by the Timer Queue when timeouts and
          cancellations occur.

          No changes occured to the algorithms of the different
          implementations of the Timer Queues (Timer List and Timer
          Heap). Timer Queues, Timer List, and Timer Heap were all renamed
          as <class>_T. However, typedef were added such that there is now
          an ACE_Timer_Queue, ACE_Timer_Heap, and ACE_Timer_List, each
          being an instantiation of the respective template classes. The
          instantiation is done with ACE_Event_Handler as the type of data
          to be stored in Timer Queue and
          ACE_Event_Handler_Handle_Timeout_Upcall as the FUNCTOR that does
          the appropriate upcall to ACE_Event_Handler.

          Due to these typedefs, 99.9% of existing code should not
          break. However, the following two will cause problems:

          (a) Forward declarations of Timer_Queue will not work! This is
          because Timer_Queue is now a typedef and not a class.

          (b) #include "ace/Timer_Queue.h" will not be enough to get the
          ACE_Timer_Queue typedef. The new typedefs are in a new file
          called Timers.h. This file also has typedefs for ACE_Timer_Heap
          and ACE_Timer_List.

          Currently Proactor is the only class that uses a different
          instantiation of the Timer Queue class. Proactor's Timer Queue
          class is instantiated with ACE_Handler as the type of data to be
          stored in Timer Queue and ACE_Proactor_Handle_Timeout_Upcall as
          the FUNCTOR that does the appropriate posting to the Proactor's
          completion port.

          The Upcall Strategy is not needed any more cause it is replaced
          by the FUNCTORs. Thus this is removed.
        
          Small modifications were made to the following files
          because of the changes to Timer_Queue.

          - examples/Reactor/Misc/test_timer_queue.cpp
          - examples/Reactor/Proactor/test_timeout.cpp
          - tests/Timer_Queue_Test.cpp
          - ace/Makefile (both UNIX and Win32)
          - ace/Connector.h
          - ace/Reactor.h
          - ace/ReactorEx.h
          - ace/Proactor.h

        * ace/Proactor: Proactor now uses the new timer queues. Proactor's
          Timer Queue class is instantiated with ACE_Handler as the type
          of data to be stored in Timer Queue and
          ACE_Proactor_Handle_Timeout_Upcall as the FUNCTOR that does the
          appropriate posting to the Proactor's completion port. This will
          help reduce the overhead of creating new act for each
          timer. This also enables the cancellation of entire
          ACE_Handlers.

        * examples/Reactor/Misc: Added Win32 makefiles.

        * ace/Shared_Memory_MM.i: Fixed typo.

        * ace/SOCK_Connector.cpp: Fixed typo.

Thu Apr 24 13:56:28 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/SOCK_Dgram.cpp: Added support for FreeBSD (i.e., BSD 4.4)
          features for passing file descriptors between processes.  Thanks
          to Nanbor Wang <nw1@cs.wustl.edu> for reporting this.

        * ace/LSOCK_Stream.cpp: Added support for FreeBSD (i.e., BSD 4.4)
          features for passing file descriptors between processes.  Thanks
          to Nanbor Wang <nw1@cs.wustl.edu> for reporting this.

        * ace/LSOCK.cpp: Added support for FreeBSD (i.e., BSD 4.4)
          features for passing file descriptors between processes.  Thanks
          to Nanbor Wang <nw1@cs.wustl.edu> for reporting this.

        * ace/SOCK_Connector.cpp (complete): There's a bug in WinNT that
          causes non-blocking connects to fail.  The workaround is to
          sleep for 1 millisecond.  Thanks to Steve Huston
          <shuston@riverace.com> for reporting this.

        * ace/Connector.cpp (handle_output): There's a bug in WinNT that
          causes non-blocking connects to fail.  The workaround is to
          sleep for 1 millisecond.  Thanks to Steve Huston
          <shuston@riverace.com> for reporting this.

        * tests/Conn_Test.cpp: Changed from operator != to operator == to
          be consistent with what is required by the ACE_Hash_Map_Manager.

        * ace/Hash_Map_Manager: Factored out the equality comparison into
          an equal() method in order to facilitate template
          specialization.  In addition, rather than using the != operator
          we now default to using the operator== operator and negating the
          result.  This is consistent with the behavior of the
          ACE_Map_Manager.

        * ace/Map_Manager: Factored out the equality comparison into an
          equal() method in order to facilitate template specialization.

        * ace/OS.i: Added a new #ifdef called ACE_LACKS_PTHREAD_CANCEL.
          I'm not sure which platforms should set this, but it fixes
          a bug with ACE_OS::thr_cancel().  Thanks to Eric Dean
          Russell <edrusse@somnet.sandia.gov> for reporting this.

        * tests/Process_Strategy_Test.cpp (handle_input): We were
          comparing EOF to a char, which gets complaints on platforms
          where char is unsigned by default.  I added a cast of EOF to
          char to fix this.  Thanks to Amos Shapira <amos@dsi.co.il> for
          reporting this.

        * apps/JAWS/server/HTTP_Helpers.cpp (instance): Changed the
          return type from const char * to const char **.  Thanks to
          Amos Shapira <amos@dsi.co.il> for reporting this.

        * ace/OS.i (getpwnam_r): Added a missing #else.  Thanks to
          Amos Shapira <amos@dsi.co.il> for reporting this.

        * ace/Timer_Heap: Made many minor enhancements to ACE_Timer_Heap
          in an effort to figure out why we're getting memory leaks.

Thu Apr 24 09:33:53 1997  David L. Levine  <levine@cs.wustl.edu>

        * Makefile: modified the TIMESTAMP macro to update the third
          component, if there is one, of the version number in the VERSION
          file.  This assumes that alpha/beta releases are numbered with
          three components, and that final releases are not.  So, if the
          version number is, e.g., 4.2, it will not be modified because it
          is assumed to be for a final release.  Manual switching between
          alpha/beta and final release "modes" is therefore still required.

        * ace/Timer_Heap.cpp (copy): added cast of max_size_ to int to avoid
          signed/unsigned comparison.

        * ace/config-sunos5.4-g++.h: removed
          ACE_HAS_CONSISTENT_SIGNAL_PROTOTYPES because it caused compile
          warnings about conversion from `(int)' to `(...)' at Signal.i:113.
          (And the other sunos5.4 config files don't have it.)
          Thanks to Joey Zhu <joey.zhu@wcom.com> for reporting this.

        * tests/Timer_Queue_Test.cpp (main): added delete of timer_ids array
          to avoid memory leak.

Wed Apr 23 22:56:57 1997  Sumedh Mungee <sumedh@cs.wustl.edu>

        * apps/JAWS/client/*:  Fixed warnings due to size_t
        * apps/JAWS/client/Blob_Handler: Fixed error by passing
          pointer to base class ACE_Blob_Handler instead
          of pointing to ACE_Blob_Reader, in call to connect

Wed Apr 23 20:57:35 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * ace/OS.i and ace/OS.h: added methods for getpwnam and
          getpwnam_r, with hooks for NT.

        * ace/config-irix6.2.*: added ACE_LACKS_PWD_REENTRANT_FUNCTIONS.
        
Wed Apr 23 14:27:48 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Timer_Queue.cpp (ACE_Timer_Queue ctor): reordered initializers
          to match declaration order.

        * tests/Process_Strategy_Test.cpp: added ACE_Singleton template
          specialization.  In function client (), null terminated "buf"
          before call to ACE_OS::strrchr () to avoid uninitialized memory
          read.  Also, fixed typo in test name (argument to ACE_START_TEST).

        * examples/Service_Configurator/Misc/Timer_Service.cpp (init): changed
          type of loop index to int to avoid signed/unsigned comparison, and
          initialized "interval" so that it has a value even if one isn't
          specified on the command line.

Wed Apr 23 10:52:45 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/OS.cpp (thr_create): Removed errant preprocessor conditional
          for determining the scheduling priority.  Thanks to Thilo Kielmann
          <kielmann@informatik.uni-siegen.de> for reporting this.

Wed Apr 23 09:06:52 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * tests/Process_Strategy_Test.cpp: Finished updating this program
          so that it is an automated test.

        * ace/Acceptor.h: Moved get_handle() into the public portion of
          the Acceptor.

        * include/makeinclude/platform_irix6.2_sgic++.GNU (SOBUILD): There
          was an extra @ in $@@.  Thanks to Amos Shapira <amos@dsi.co.il>
          for reporting this.

        * apps/JAWS/client/Blob[_Handler].cpp: Added casts for free ((void
          *) filename_);.  Thanks to Amos Shapira <amos@dsi.co.il> for
          reporting this.

        * apps/JAWS/server/HTTP_Helpers.h (class HTTP_Status_Code):
          Removed an extraneous const * from the definition of instance().
          Thanks to Amos Shapira <amos@dsi.co.il> for reporting this.

Wed Apr 23 03:15:11 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * apps/JAWS/server/README: Updated to add some clarity and more
          useful information.

Tue Apr 22 20:17:00 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Synch.cpp: Added a new method called open() to ACE_File_Lock
          so that we don't have to initialize it solely in the
          constructor.

        * tests/Process_Strategy_Test.cpp: Added new test code that
          exercises the ACE_Process_Strategy, ACE_Thread_Strategy, and
          ACE_Reactive_Strategy classes.

        * ace/Strategies_T: Added a new class called
          ACE_Reactive_Strategy, which inherits from
          ACE_Concurrency_Strategy and registers new Svc_Handlers with the
          Reactor.

        * ace/Strategies_T.cpp (ACE_Thread_Strategy): Added a check for
          failed open() methods and call ACE_ERROR.

        * tests/Map_Manager_Test.cpp: Added a template specialization for
          the ACE_Hash_Map_Manager::hash() method, which is enabled if the
          compiler supports template specializations.

        * ace/Hash_Map_Manager.h (pool): Moved the ext_id.hash() call into
          a separate method so that we can perform template specialization
          of it more easily.

        * ace/README: Added a new #define called
          ACE_HAS_TEMPLATE_SPECIALIZATION so that we can work around funky
          compilers that don't support this advanced template feature.

        * ace: Added Nanbor Wang's port to FreeBSD.  The port is done
          at FreeBSD 3.0-current as of 2/9/97, which is the
          latest stable system before Lite2 merge.  Since the merge is
          current under testing and changes are introduced in a daily
          basis, I don't recommend using -current after the date.  You
          can specified the date in your "supfile", run CVSup to get the entire 
          source tree and do a 'make world' to update (or reverse) your
          system.
 
          Pthread library is provided by John Birrell.  There is a
          bug fix at mid April so you may want to CVSup the latest libc_r
          library and re-make the pthreaded library.
 
          A shared library must be name as lib<name>.so.<version
          number> (e.g. libACE.4.1.0).  I would recommend adding a
          post-compile hook in the Makefile so we FreeBSDers can
          rename the shared library to it's proper name with correct
          major and minor version number attached.  (which is a trick
          BSD library makefiles use.) 

        * examples/OS/Process/process.cpp (main): Replaced the use of
          "/bin/cat" with "cat" since we are now using execvp().  Thanks
          to Nanbor Wang <nw1@cs.wustl.edu> for reporting this.

        * ace/Process.cpp (start): Changed the use of execv() to execvp()
          in order to avoid having to pass in the full pathname.

        * ace/OS.i (sigwait): Added an #ifdef for FreeBSD so that we
          return ACE_NOTSUP_RETURN(-1) for ACE_OS::sigwait().  Thanks to
          Nanbor Wang <nw1@cs.wustl.edu> for reporting this.

Tue Apr 22 17:46:30 1997    <harrison@samba.cs.wustl.edu>

        * Process.cpp (start): We must pass in 0 instead of "" to
          CreateProcess for the current working directory.

Tue Apr 22 01:38:14 1997    <irfan@TWOSTEP>

        * ace/Timer_Queue: Added ACE_Upcall_Strategy as a parameter to the
          constructor.  <expire> will call <upcall_strategy->upcall> if
          <upcall_strategy> is not 0. Else it will call <handle_timeout>
          on the <Event_Handler>. Thus ACE_Upcall_Strategy becomes a
          vehicle for extending the behavior of ACE_Timer_Queue wrt the
          upcall (callback) *without subclassing*.  Hence, it's an example
          of the Bridge/Strategy patterns.

          This also affected ACE_Timer_List and ACE_Timer_Heap

        * ace/Strategies: Added ACE_Upcall_Strategy.

        * ace/Proactor: Added timing support to the <handle_event> calls.

        * ace/Asynch_IO: ACE_Handler now supports handle_timeout.

        * ace/Proactor: Added timer support for the new Proactor.  This
          new scheme allows any of the threads in the "thread pool"
          waiting on the completion port of the Proactor to execute the
          callback routine of the handler.

          The implementation included adding ACE_Proactor_Timer_Handler
          class that has a thread that will wait on the earliest time in a
          timer queue and an event. When a timer expires, the thread will
          post a completion event on the port and go back to waiting on
          the timer queue and event. If the event is signaled, the thread
          will refresh the time it is currently waiting on (in case the
          earliest time has changed).

          The ACE_Proactor::Asynch_Timer class is posted to the completion
          port when a timer expires. When the <complete> method of this
          object is called, the <handler>'s handle_timeout method will be
          called.
        
        * examples/Reactor/Proactor/test_timeout: This example illustrates
          the new timer features in the Proactor

        * examples/Reactor/Proactor/test_proactor.{mdp,mak}: Added new
          example.

Mon Apr 21 18:14:32 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/config-win32-common.h: Added checks around _AFXDLL before
          defining it. Thanks to Bruce Meyer <bmeyer1@gte.net> for
          pointing this out.

Mon Apr 21 11:31:16 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp:
        Removed some unnecessary explicit template instantiations.

        * examples/Threads/barrier1.cpp (main): Explicitly converted
        n_threads to int.

Sun Apr 20 23:08:37 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/{Local,Remote}_Tokens.h: Added a private declarations of the
          copy constructor and assignment operator for classes that
          inherit from ACE_TSS. This is necessary since the compiler will
          auto generate these two operations that will end up using the
          non-existent copy constructor and assignment operator from the
          TSS class and cause linker errors.

Sun Apr 20 20:47:34 1997  Sumedh Mungee       <sumedh@cs.wustl.edu>

        * apps/JAWS/client: Reworked the ACE_Blob* classes to work
          with the new Connector behavior. Added README for this 
          directory. Added comments.

        * apps/JAWS/stress-testing: Added README file
        
Sun Apr 20 13:11:25 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * apps/Makefile: By default, we now compile JAWS along with the
          rest of ACE.  I've also added some README files that explain
          what JAWS is all about.

        * examples/Service_Configurator/Misc/Timer_Service: Improved the
          Timer_Service test so that it makes more sense and is better
          documented.

Sat Apr 19 11:56:35 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * include/makeinclude: Removed the platform_irix6.2_sgiCC.GNU
          from the release.  Thanks to Torbjorn Lindgren
          <tl@funcom.no> for these fixes.

        * include/makeinclude/platform_irix6.2_sgic++.GNU: Updated the SGI
          C++ platform config file.  Thanks to Torbjorn Lindgren
          <tl@funcom.no> for these fixes.

        * ace/Log_Msg.cpp (log_hexdump): The char * arguments should be
          const char *'s.  Thanks to Matthias Kerkhoff
          <make@cs.tu-berlin.de> for reporting this.

Sat Apr 19 18:52:44 1997  David L. Levine  <levine@cs.wustl.edu>

        * (format_hexdump): changed type of first arg to const char *
          for compatibility with Log_Msg::log_hexdump ().

Thu Apr 17 08:25:06 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Memory_Pool.h: Fixed a couple of typos in Memory_Pool
          classes.  Thanks to Neil B. Cohen <nbc@metsci.com> for reporting
          this.

        * netsvcs/lib/Name_Handler.h: Arrgh, there was still one more
          missing #include that I forgot to move into the *.h file.
          Thanks to David Levine for noticing this.

        * ace/Synch.cpp (wait): There was a bug in
          ACE_Condition::wait(MUTEX& mutex, const ACE_Time_Value
          *abstime.)  Basically when abstime is zero, it ignores the
          parameter "mutex" that has been passed to it and instead goes on
          to call "ACE_Condition<MUTEX>::wait()" which uses "this->mutex_"
          as the mutex to be released and not the mutex that the caller
          has given.  The fix is to change the call "this->wait()" in the
          if-clause to:  

          return ACE_OS::cond_wait (&this->cond_, &mutex_.lock_);

          Thanks to Ashish Singhai <Ashish.Singhai@ACM.ORG> for reporting
          this.

Thu Apr 17 16:33:21 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Memory_Pool.cpp: fixed typos in ACE_MMAP_Memory_Pool_Options
          constructor declaration and initializer list.  In init_acquire,
          added cast of minimum_bytes_ to size_t to avoid signed/unsigned
          comparison.

        * include/makeinclude/{platform*,wrapper_macros}.GNU:
          moved -g out of wrapper_macros.GNU and into each platform
          file so that -gstabs can be used on SCO.  Thanks to
          Ganesh Pai <gpai@voicetek.com> for reporting that problem.

          (The real change was getting rid of the CFLAGS += DCFLAGS
          default.  We could have left DCFLAGS=-g in wrapper_macros.GNU
          and overridden for SCO.  But the way I changed things, the
          C/CFLAGS pieces are together in each platform file, so they're
          easier to find.)

Wed Apr 16 17:05:55 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Memory_Pool.cpp (acquire): Added code to enable a minimum
          bytes field with the Shared_Memory_Pool.  Thanks to Fred LaBar
          <flabar@fallschurch.esys.com> for these enhancements.

        * tests/Process_Strategy_Test.cpp: Only compile this test if
          ACE_LACKS_EXEC is *not* defined since ACE_Process_Strategy
          requires fork().  Thanks to Irfan for pointing this out!

        * netsvcs/lib: Fixed a couple o' typos that had escaped detection
          last night.  Thanks to David Levine for reporting this.

        * ace/Synch[_T].h: removed the use of {} rather than ; for
          the private copy constructors and assignment operators.
          Hopefully this won't break code on older C++ compilers.  Thanks
          to Berni Merkle <merkle@io.freinet.de> for suggesting this.

        * Added a whole slew of minor fixes for unused variables in
          the tests and examples.  Thanks to Torbjorn Lindgren
          <tl@funcom.no> for reporing these.

        * ace/Handle_Set.cpp (ACE_Handle_Set_Iterator): The order of 
          the clause

          this->handles_.mask_.fds_bits[this->index_] == 0
          && this->num_ < ACE_Handle_Set::MAXSIZE

          was backwards.  It should be:

          this->index_ < ACE_Handle_Set::NUM_WORDS
          && this->handles_.mask_.fds_bits[this->index_] == 0

          Thanks to Michael Newton <michaeln@in.ot.com.au> for
          reporting this.

Wed Apr 16 21:34:53 1997  David L. Levine  <levine@cs.wustl.edu>

        * tests/Process_Strategy_Test.cpp: added template specializations.

Wed Apr 16 15:46:58 1997    <irfan@TWOSTEP>

        * tests/Process_Strategy_Test: Added test to batch files and
          MSVC++ Makefiles.

        * tests/Process_Strategy_Test.cpp (open): Added UNICODE support.

        * ace/OS.h: Added SIGCHLD to Win32 section.

        * ace/config-win32-common.h: UNICODE should not be automatically
          defined if ACE_HAS_UNICODE is defined. ACE_HAS_UNICODE signifies
          that the OS has UNICODE support. It does not mean that your code
          must be UNICODE. UNICODE must be defined at the project level.

Wed Apr 16 16:55:47 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/SString.{h,cpp}: Modified CString to not allocate 1 byte for
          a 0 length string.  Instead, set the internal representation to
          the address of static class character null_string_.

Wed Apr 16 11:47:35 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/Map_Manager.cpp (free_search_structure): Added the loop
          variable back in that must have been inadvertently deleted in the
          previous entry.

Wed Apr 16 09:35:39 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Map_Manager.cpp (free_search_structure): changed type of
          loop index to size_t to avoid signed/unsigned mismatch.

Wed Apr 16 04:07:50 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Strategies_T: Widened the constructor interface for
          ACE_Process_Strategy based on the feedback I got from
          implementing the Process_Strategy_Test.cpp program.

        * tests/Process_Strategy_Test.cpp: Added an interesting new test
          that illustrates the use of the ACE_Process_Strategy and the
          ACE_File_Lock.  To exercise this program, you can telnet to it
          and type "read" and "inc" to query and change the count of
          the numbers in the file, respectively.

        * ace/Connector.cpp (create_AST):  I fixed a couple of things
          in Connector.cpp: 

          - In create_AST, it needs to save and restore errno, else it
            gets wiped on Win32 and other platforms.

          - On Win32 when a non-blocking connect completes and handle_output is
            called, it tries to get the peer address.  If done too quickly, it
            fails.  I put in a Sleep(0) call.  I think this is not a great
            solution, but I don't have a better one yet.
            
          Thanks to Steve Huston <shuston@riverace.com> for fixing
          these bugs. 

Tue Apr 15 17:09:33 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/SOCK_Stream.cpp (close): Removed the call to close_writer()
          on UNIX since that doesn't do the correct thing in many
          cases since it causes a protocol transmission which isn't
          what we want if we're using fork().

        * ace/Strategies_T.cpp (activate_svc_handler): Added a call to
          svc_handler->destroy() in the parent since we don't need it and
          we're leaking descriptors and memory otherwise...  Thanks to
          Kevin Boyle <kboyle@sanwafp.com> for reporting this.

        * ace/OS.i (thr_sigsetmask): Replaced the use of
          PTHREADS_1003_DOT_1C with ACE_HAS_PTHREAD_SIGMASK.  Thanks to
          Arturo Montes <mitosys@colomsat.net.co> for suggesting this.

        * ace: Changed all uses of ACE_HAS_PTHREADS_XAVIER to
          ACE_HAS_PTHREAD_SIGMASK, which is more descriptive.  Thanks to
          Arturo Montes <mitosys@colomsat.net.co> for suggesting this.

        * ace/config-aix-4.2.x.h: Added #define ACE_LACKS_RWLOCK_T to make
          things compile with AIX 4.2.  Thanks to Jeremy Buch
          <davinci@nortel.ca> for reporting this.

        * ace/XtReactor.cpp (register_handler_i): Added "[]" to delete
          this->ids_ since it is an array.  Thanks to Jean-Marc Strauss
          <strauss@club-internet.fr> for reporting this.

        * netsvcs/lib: Moved all the class definitions into the *.h files
          to avoid complaints from the IBM C++ compiler.

        * ace/OS.h: Added a #define for WNOHANG since this is missing on
          NT.  Thanks to Brian Mendel <bmendel@mdc.com> for reporting
          this.

        * examples/Connection/non_blocking/test_sock_connector.cpp: Added
          a typedef for ACE_RW_Mutex so that the code compiles on non-MT
          platforms.  Thanks to Ganesh Pai <gpai@voicetek.com> for
          reporting this.

        * examples/Connection/non_blocking/test_tli_connector.cpp: Added a
          typedef for ACE_RW_Mutex so that the code compiles on non-MT
          platforms.  Thanks to Ganesh Pai <gpai@voicetek.com> for
          reporting this.

        * examples/Connection/misc/test_upipe.cpp: Added a typedef for
          ACE_RW_Mutex so that the code compiles on non-MT platforms.
          Thanks to Ganesh Pai <gpai@voicetek.com> for reporting this.

        * performance-tests/Synch-Benchmarks/Options.cpp: Added a #ifdef
          for ACE_Thread_Mutex so that the code compiles on non-MT
          platforms.  Thanks to Ganesh Pai <gpai@voicetek.com> for
          reporting this.

        * examples/ASX/Event_Server/Transceiver/transceiver.cpp: Added a
          typedef for ACE_RW_Mutex so that the code compiles on non-MT
          platforms.  Thanks to Ganesh Pai <gpai@voicetek.com> for
          reporting this.

        * examples/ASX/UPIPE_Event_Server/Consumer_Router.cpp: Added a
          typedef for ACE_RW_Mutex so that the code compiles on non-MT
          platforms.  Thanks to Ganesh Pai <gpai@voicetek.com> for
          reporting this.

        * examples/ASX/Event_Server/Event_Server/Options.cpp
          (print_results): Although rusage struct is defined on SCO, there
          is no getrusage(), rusage is used only by wait()
          etc. internally.  Therefore, we had to move some #ifdefs around.
          Thanks to Ganesh Pai <gpai@voicetek.com> for reporting this.

        * apps/Gateway/Gateway/Proxy_Handler_Connector.cpp: Added a
          typedef for ACE_RW_Mutex so that the code compiles on non-MT
          platforms.  Thanks to Ganesh Pai <gpai@voicetek.com> for
          reporting this.

        * tests/Conn_Test.cpp: Added a typedef for ACE_RW_Mutex so that
          the code compiles on non-MT platforms.  Thanks to Ganesh Pai
          <gpai@voicetek.com> for reporting this.

        * tests/SPIPE_Test.cpp (main): Removed the VXWORKS arm of the
          #ifdef, which is not correct since this stuff only works if
          we're working with a version of VxWorks that has STREAM pipes.

        * include/makeinclude/platform_sco5.0.0-nothread.GNU: Changed
        
          LIBS            = -lsocket -lnsl -ldl

          to

          LIBS            += -lsocket -lnsl -ldl

          Thanks to Ganesh Pai <gpai@voicetek.com> for reporting this.

        * netsvcs/lib/Client_Logging_Handler.cpp: Added a typedef for
          ACE_RW_Mutex so that the code compiles on non-MT platforms.
          Thanks to Ganesh Pai <gpai@voicetek.com> for reporting this.

        * netsvcs/lib/TS_Clerk_Handler.cpp: Added a typedef for
          ACE_RW_Mutex so that the code compiles on non-MT platforms.
          Thanks to Ganesh Pai <gpai@voicetek.com> for reporting this.

        * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: Added a
          typedef for ACE_RW_Mutex so that the code compiles on non-MT
          platforms.  Thanks to Ganesh Pai <gpai@voicetek.com> for
          reporting this.

Tue Apr 15 23:16:43 1997    <harrison@samba.cs.wustl.edu>

        * ace/[Hash_]Map_Manager.cpp: The [Hash_]Map_Manager now
          explicitly calls the destructors of Map_Entry objects before
          freeing up the space.  Not sure why we were not doing this
          before...

Tue Apr 15 17:09:33 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * examples/Logger: Added MSVC++ makefile to Acceptor-server
          and client.

Tue Apr 15 21:51:45 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * apps/JAWS/server/IO.cpp: Added a template instance for
          ACE_Singleton so it would link using GCC.  Removed GCC
          warnings.

        * apps/JAWS/server/HTTP_Server.cpp: Added template instances for
          LOCK_SOCK_Acceptor, ACE_Task, ACE_Thru_Task, ACE_Message_Queue,
          ACE_Module so it would link using GCC.  Removed GCC warnings.

        * apps/JAWS/server/HTTP_Server_T.cpp: Removed template instance of
          LOCK_SOCK_Acceptor, since it was not really being compiled.

Tue Apr 15 21:51:45 1997  James C Hu  <jxh@polka.cs.wustl.edu>

        * apps/JAWS/server/IO.cpp: Added a template instance for
          ACE_Singleton so it would link using GCC.  Removed GCC
          warnings.

        * apps/JAWS/server/HTTP_Server.cpp: Added template instances for
          LOCK_SOCK_Acceptor, ACE_Task, ACE_Thru_Task,
          ACE_Message_Queue, ACE_Module so it would link using GCC.
          Removed GCC warnings.  

        * apps/JAWS/server/HTTP_Server_T.cpp: Removed template
          instance of LOCK_SOCK_Acceptor, since it was not really
          being compiled. 

        * apps/JAWS/server/HTTP_Handler.cpp: Removed GCC warnings.

Tue Apr 15 13:01:13 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Token_Request_Reply.cpp (ctor): added initialization of
          transfer_.data_ to avoid unitialized memory read.

        * tests/test_config.h: removed "static" qualifier from
          randomize () to avoid warning from g++ when it's not called
          in a test.  

        * examples/IPC_SAP/SPIPE_SAP/server.cpp (main): moved
          declaration of local variable "handle" up before its first
          use. 

Tue Apr 15 17:09:33 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * examples/Connection/blocking/Makefile: Removed the Makefile
          for this test. This example is only suppose to work on WIN32
          and therefore the Makefile is not necessary. I have replace
          this file with a MSVC++ make file.

Mon Apr 14 23:08:27 1997    <irfan@TWOSTEP>

        * INSTALL: Updated install files for Win32.

        * ace/SPIPE_Stream: Changed the use of ACE::send_n to ACE::write_n
          and ACE::recv_n to ACE::read_n.

        * ace/OS.h (WNOHANG): Added WNOHANG to OS.h for Win32.

        * ace/OS.i (getpgid): Fixed extra return.

        * examples/Connection/blocking/SPIPE-acceptor: Updated the code to
          use the new Proactor and the new asynchronous IO.     

Mon Apr 14 21:32:24 1997  David L. Levine  <levine@cs.wustl.edu>

        * examples/IPC_SAP/SOCK_SAP/FD-unserver.cpp (handle_client):
          ACE_OS::sprintf instead of sprintf.

        * examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp
          (svc): declare "t" as time_t instead of long.

          Thanks to Thilo Kielmann <kielmann@informatik.uni-siegen.de> for
          reporting both of these.

Mon Apr 14 00:02:39 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/OS.i (getpgid): Removed the extraneous return in front of
          ACE_NOTSUP_RETURN.  Thanks to Mike Bernat <sagmb@sagus.com> for 
          reporting this.

        * ace/Process.cpp: Replaced the use of ACE_OS::fork(void) with
          ACE_OS::fork(const char *) so that we can pass in the name of
          the process we're exec'ing.

        * examples/Threads/process_manager.cpp: Added a test program that
          exercises the features of the new ACE_Process_Manager.

        * ace/Process_Manager: Finished a rudimentary implementation of
          ACE_Process_Manager.  There's still plenty of work to be done on
          this, however...

        * ace/Thread_Manager.cpp (dump): Added dump() methods for
          ACE_Thread_Descriptor and ACE_Thread_Manager.

Sun Apr 13 11:40:26 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/OS: Added a getpgid() call to ACE_OS.

        * ace/Thread_Manager: Changed the 'int n' of spawn_n() to size_t n
          since this is more appropriate because we can't spawn a negative
          number of threads...

        * ace/Thread_Manager.cpp (close): Make sure to lock the calls to
          close() in case things get amiss.

        * ace/Process.cpp (start): Updated ACE_Process::start() to that it
          doesn't try to exec() a program if argv == 0.  This allows us to
          use ACE_Process to fork() a process without exec'ing.

        * tests/Timer_Queue_Test.cpp (randomize_array): Added a new
          "randomization" test that determines the performance of randomly
          canceling items in the array.  Thanks to Darrell Brunsch
          <brunsch@cs.wustl.edu> for this enhancement.

        * tests/test_config.h: Moved the randomize() function from
          Naming_Test.cpp to test_config.h so that we can use it in other
          tests (e.g., the new Timer_Queue_Test.cpp that Darrell is
          working on).

        * ace/OS: Added a new #define called ACE_HAS_NONCONST_MSGSND which
          can be used for platforms (e.g., SCO) that don't have a const
          parameter for msgsend().  Thanks to Arturo Montes
          <mitosys@colomsat.net.co> for reporting this.

        * ace/config-sco-5.0.0-mit-pthread.h: Added some fixes to make
          this work on SCO.  Thanks to Arturo Montes
          <mitosys@colomsat.net.co> for reporting this.

        * ace/OS.i (cond_timedwait): There is a *small* chance for a
          context switch before ACE_OS::cond_timedwait() is reached.  In
          this case, the current time *may* advance by some milliseconds.
          The code in ACE_OS::cond_timedwait() then converts the given
          absolute time to a relative time.  In the described situation
          this will be a very, very long t ime (0xfffffffn).  Therefore, I
          added a check to avoid the "negative timespan" case.  Thanks to
          Matthias Kerkhoff <make@cs.tu-berlin.de> for suggesting this.

        * ace/Set: Moved all the size() methods out of the *.i file and
          into the *.cpp file to avoid problems with quirky compilers
          (e.g., SGI) that can't handle this.  Thanks to Torbjorn Lindgren
          <tl@funcom.no> for pointing this out.

        * examples/Threads/process_semaphore.cpp (main): Removed a stray
          ^M that was causing the SGI C++ compiler some grief.  Thanks to
          Torbjorn Lindgren <tl@funcom.no> for pointing this out.

        * ace/OS.i (gettimeofday): Rearranged the code a bit to return
          errors correctly if they occur (which should be *very*
          unlikely).  Thanks to Torbjorn Lindgren <tl@funcom.no> for
          pointing this out.

        * netsvcs/lib/Server_Logging_Handler.cpp: Replaced the use of
          ACE_TLI* with LOGGING_PEER*.  Thanks to Tom Wright
          <twright@gem-net.demon.co.uk> for reporting this.

        * ace/Connector.cpp: Made sure to initialize all of the instance
          variables for the ACE_Strategy_Connector and ACE_Connector.
          Thanks to David Levine for pointing this out.

        * ace/Synch.h: Changed protected: to private: so that we can
          ensure that we never copy classes like ACE_File_Lock, etc.
          Thanks to Berni Merkle <merkle@io.freinet.de> for reporting
          this.

        * examples/Shared_Malloc/test_malloc.cpp (malloc_recurse): Added
          the print_stats() call back into the test since Sandro's fixes
          should now support this.

        * ace/Malloc[_T]: Added patches to enable ACE_Allocator's to print
          malloc statistics.  Thanks to Sandro Doro
          <alex@aureus.sublink.org> for these fixes.

Sat Apr 12 20:42:11 1997  David L. Levine  <levine@cs.wustl.edu>

        * tests/Priority_Task_Test.cpp (open): only use THR_SCHED_FIFO
          if it is defined.  (It isn't on Solaris without PTHREADS.)

        * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp
          (make_svc_handler): added return statement.

Sat Apr 12 11:53:49 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * examples/ASX/Event_Server/Transceiver/transceiver.cpp (main):
          The first argument to connect () is now a SVC_HANDLER *&.
          Therefore, we can no longer allows us to pass the address of a
          SVC_HANDLER on the stack (or in the data segment).
          Fortunately, the fix is easy, as shown below:

          Event_Transceiver transceiver, *tp = &transceiver;

          connector.connect (tp, ACE_INET_Addr (port_number, host_name));

          Thanks to David Levine for reporting this problem.

Fri Apr 11 15:14:59 1997  David L. Levine  <levine@cs.wustl.edu>

        * tests/Conn_Test.cpp: moved declaration of "result" out of
          loop because it's used after the loop.  Thanks to
          Thilo Kielmann <kielmann@informatik.uni-siegen.de> for
          reporting this.  Also, removed a few unnecessary template
          specializations.

        * apps/Gateway/Gateway/Proxy_Handler_Connector.cpp: fixed template
          specializations for no-thread platforms.  Thanks to Ganesh Pai
          <gpai@voicetek.com> for reporting this.

        * performance-tests/Misc/context_switch_time.cpp (main):
          removed call to ACE_High_Res_Timer::supported ().

Fri Apr 11 14:31:42 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * tests/Conn_Test.cpp: Added several explicit template
          instantiations.

Fri Apr 11 13:49:04 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: VxWorks changes only:  added taskHookLib.h.  Thanks
          to Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com> for reporting
          that.  Also rearranged the VxWorks #includes and such a bit.

        * ace/Log_Msg.cpp (atexit): VxWorks changes only:  added cast
          of spare1 to ACE_Log_Msg *.  Thanks to Dave Mayerhoefer
          <mayerhoefer@svappl36.mdc.com> for reporting that.  Also,
          in exists () and instance (), replaced double indirection
          of the ACE_Log_Msg instance with indirection through a pointer
          reference.

        * ace/High_Res_Timer.{h,i}: removed supported () because
          ACE_OS::gettimeofday () is used if a high-res timer isn't available.

        * ace/OS.i (thr_sigsetmask),config-sunos5.4-*.h: swapped order of
          #ifdefs to that ACE_LACKS_PTHREAD_THR_SIGSETMASK is checked before
          ACE_HAS_STHREADS.  Added that #define to all SunOS 5.4 configs.
          Thanks to Joey Zhu <joey.zhu@wcom.com> for reporting this.

        * ace/Token_Request_Reply.cpp (ctor): added a initializations to 0
          of requeue_position_, notify_, and arg_.  With this change, all
          of the ACE tests run without any Purify access anomalies!
          (There are still some memory leaks, though.)

        * include/makeinclude/rules.local.GNU: added -DMAKEDEPEND to
          invocation of g++dep.  This allows users to get proper
          dependencies if they have conditional #includes in their code.
          They can added #if defined (MAKEDEPEND) as necessary to make
          sure that all headers are seen by g++dep.

Fri Apr 11 10:46:56 1997  Chris Cleeland  <cleeland@cs.wustl.edu>
        
        * config-linux*.h: Added ACE_HAS_IP_MULTICAST as the default for
          all Linux configurations.  If you're a 1.x user, or you didn't
          config that into your 2.x kernel, you'll have to remove this from
          your version of the file.

Thu Apr 10 00:34:10 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * examples/Logger/simple-server/Logging_Acceptor.cpp
          (handle_input): We need to call svc_handler->close() if accept()
          or open() fails.  Thanks to Ganesh Pai <gpai@voicetek.com> for
          reporting this.

        * ace/Service_Config.cpp (close): Moved the call to
          ACE_Service_Config::close_singletons() to outside the check for
          ACE_Service_Config::svc_rep_ since the Singletons can be used
          independently of the services.  Thanks to Matthias Kerkhoff
          <make@cs.tu-berlin.de> for suggesting this.

Wed Apr  9 21:11:38 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * apps/Gateway/Gateway/Gateway.cpp (handle_signal): Evil demons
          added bugs to my code that were causing segfaults when signals
          shutdown the gateway.  This is now fixed.

        * apps/Gateway/Gateway/Proxy_Handler.h: Changed ACE_Event_Channel
          & to ACE_Event_Channel * to keep the compiler happy.

        * examples/Connection/non_blocking/CPP-connector.h: Added a
          do-nothing default constructor to keep ACE_Connector happy.

        * examples/Connection/misc/test_upipe.cpp: Added a do-nothing
          default constructor to keep ACE_Connector happy.

        * examples/Connection/blocking/SPIPE-connector.h: Added a
          do-nothing default constructor to keep ACE_Connector happy.

        * apps/Gateway/Gateway/Proxy_Handler: Added a do-nothing default
          constructor to keep ACE_Connector happy.

        * netsvcs/lib: Added some default arguments to
          TS_Clerk_Handler.cpp and Client_Logger_Handler.cpp to keep the
          compiler from complaining about the new ACE_Connector features.
          Thanks to David Levine for reporting this.

        * ace/Timer_Heap.cpp (reheap_down): Fixed a *very* subtle bug in
          reheap_down() where parent was starting off at 0 whereas it
          should have been starting off at child_index / 2.

        * examples/Logger/simple-server/Logging_Handler: Removed the use
          of the operator ACE_SOCK_Stream &() and replaced it with the
          more intuitive peer() approach used in ACE_Svc_Handler et al.
          Thanks to Ganesh Pai <gpai@voicetek.com> for reporting this.

        * ace: Added a bunch of changes to improve ACE support on SCO 5.0.
          Thanks to Ganesh Pai <gpai@voicetek.com> for these fixes.

        * tests/Conn_Test.cpp: Completely reworked this test so that it
          illustrates how to use the ACE_Strategy_Connector, which is
          customized with a special Caching_Connect_Strategy that recycles
          connections.

        * ace/Connector: Finished implementing the new
          ACE_Strategy_Connector.  This is similar in design to the
          ACE_Strategy_Acceptor.

        * ace: Changed the signature of all the make_svc_handler() methods
          so that they return int (rather than SVC_HANDLER *) and they
          pass back a SVC_HANDLER * by reference.  This makes it possible
          to totally control the creation of svc handlers (which is useful
          for the new ACE_Strategy_Connector).

        * ace/Connector.cpp: Factored out the active_svc_handler() call
          from the connect_svc_handler() method into the connect() method
          so that it would behave correctly as a Template Method and
          Strategy.

        * ace/Connector: Removed the explicit use of the Reactor data
          member from the ACE_Connector since it's inherited from the
          ACE_Service_Object.

        * ace/Log_Msg.cpp: The MVS compiler doesn't like the call to
          atexit() in ACE_Log_Msg::instance() because atexit() requires an
          a function pointer of type extern "C" for its parameter.  I've
          fixed this via an adapter.  Thanks to Chuck Gehr
          <gehr@sweng.stortek.com> for reporting this.

        * ace/Strategies_T: Added a new ACE_Connect_Strategy that
          complements the ACE_Strategy_Connector in the same manner that
          the ACE_Accept_Strategy complements the ACE_Strategy_Acceptor.

        * ace/Connector.h: The destructor for ACE_Connector should have
          been virtual.  Now it is.

        * ace/Connector: Added a new factory method called
          make_svc_handler().  This behaves similiarly to the
          ACE_Acceptor::make_svc_handler().  However, for the
          ACE_Connector we only use this when the SVC_HANDLER * is NULL.

        * ace/Connector: Changed the signature for connect() to take a &
          to a SVC_HANDLER * in anticipation of our new
          ACE_Strategy_Connector.  This new connector will make it easy to
          implement cached connections.

        * ace/config-win32-common.h: Added a new #include for <mswsock.h>,
          which contains the declarations for TransmitFile() data
          structures.  They are in WINSOCK.H if you do not use
          ACE_HAS_WINSOCK2.  Thanks to Norbert Rapp
          <norbert.rapp@nexus-informatics.de> for reporting this.

        * ace/OS.i: Fixed a typo in the new condition variable
          implementation for Win32.  Thanks to Norbert Rapp
          <norbert.rapp@nexus-informatics.de> for reporting this.

Wed Apr 09 22:06:23 1997    <harrison@samba.cs.wustl.edu>

        * Memory_Pool.h: Modified ACE_MMAP_Memory_Pool and
          ACE_MMAP_Memory_Pool_Options to include the new guess_on_fault
          option.  This is only for platforms that can not report which
          address caused a segmentation fault (via signal or exception).
          When guess_on_fault is set (via ACE_MMAP_Memory_Pool_Options),
          ACE_MMAP_Memory_Pool::handle_signal calls
          ACE_MMAP_Memory_Pool::remap "guessing" that the segmentation
          fault was caused by an access to memory not yet mapped.

Wed Apr 09 16:46:16 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.{h,i}: fixed readPPCTimeBase declaration and return
          value (for now: it really needs to return a 64 bit quantity).
          Thanks to Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com> for
          reporting these.

Wed Apr  9 03:12:24 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/config-win32-common.h: Defining _WIN32_WINNT as 0x0400
          implies ACE_HAS_WINSOCK2.
        
        * ace/Asynch_IO: The implementation of ACE_Asynch_Transmit_File
          and ACE_Asynch_Accept are only supported if ACE_HAS_WINSOCK2 is
          defined or you are on WinNT 4.0 or higher. Therefore, added
          appropriate #defines.  Thanks to Matthias Kerkhoff
          <make@cs.tu-berlin.de> for suggesting this.

Tue Apr  8 22:45:28 1997  Prashant Jain  <pjain@merengue.cs.wustl.edu>

        * java/src/SOCKStream.java (SOCKStream): Made two small changes to
          the two send(). Instead of doing a println, I now do a
          print. This was really a bug!

Tue Apr 08 22:08:12 1997  David L. Levine  <levine@cs.wustl.edu>

        * include/makeinclude/platform_sunos5_sunc++_4.1.GNU: removed
          "rm -f $@" from AR command so that archive won't be removed
          during incremental updates.  Thanks to Chuck Gehr
          <gehr@sweng.stortek.com> for reporting this.

Tue Apr  8 00:04:22 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Task_T.cpp: Added a hack to work around the new weird HP/UX
          aCC template semantics.  Thanks to Neil B. Cohen
          <nbc@metsci.com> for reporting this.
 
        * ace/config-hpux-10.x[-g++].h: Added #define
          ACE_HAS_CLOCK_GETTIME.  Thanks to Neil B. Cohen <nbc@metsci.com>
          for reporting this.

        * ace/config-hpux-10.x[-g++].h: Added ACE_HAS_IP_MULTICAST and removed
          ACE_LACKS_STRRECVFD.  Thanks to Neil B. Cohen <nbc@metsci.com>
          for reporting this.

        * ace/config-hpux-10.x.h: Apparently some HP/UX 10.x C++ compilers
          don't support volatile, so I #defined it away as a macro.
          Thanks to Neil B. Cohen <nbc@metsci.com> for reporting this.

        * ace/Log_Msg.cpp: Put a #if defined (ACE_MT_SAFE) around the
          entire Log_Msg destructor.  Thanks to Neil B. Cohen
          <nbc@metsci.com> for reporting this.

        * ace/config-hpux-10.x[-g++].h: Added #define ACE_HAS_STREAMS on
          the recommendation of Neil B. Cohen <nbc@metsci.com>.

Mon Apr 07 12:08:21 1997    <harrison@samba.cs.wustl.edu>

        * ace/Set.cpp: For some reason, VC++ 5.0 doesn't like to have the
          constructors X::X(X&) and X::X(X*).  We can change the X::X(X*)
          constructor to take in an extra argument with a default value.
          This seems to have sufficiently satisfied the VC++ 5.0 for the
          time being.  There were no changes necessary to other Set.cpp
          code (as the extra argument has a default value).

Mon Apr 07 08:05:03 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-win32.h: enabled ACE_HAS_UNICODE by default.
          Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de> for
          suggesting this.

        * ace/config-sunos5.4-g++.h: enabled ACE_HAS_BROKEN_RANDR and
          disabled ACE_HAS_SVR4_SIGNAL_T.  Thanks to Joey Zhu
          <joey.zhu@wcom.com> for reporting these problems and testing
          the fix.

        * ace/Proactor.h (ACE_Proactor): commented out unused arguments
          in non-WIN32 version.

Sun Apr 06 22:51:02 1997    <irfan@TWOSTEP>

        * ace/Proactor: Complete rewrite of Proactor that pushes all the
          differences in asynchronous I/O to the edges of the framework -
          i.e., into the new Asynch_IO classes. This allows the Proactor
          to easily support new asynchronous operations.

          Currently, the new Proactor supports minimal functionality. In
          the future, we will complete this.

          The Proactor is used in conjunction with the new Asynch_IO
          classes.  There is a different class for each operation. Please
          see Asynch_IO.h for details.

          There is also a new ACE_Asynch_Acceptor that uses AcceptEx.

          Example is in:
          ACE_wrappers/examples/Reactor/Proactor/test_proactor.cpp.  

          This example illustrates how the ACE_Proactor can be used to
          implement an application that does various asynchronous
          operations.

        * apps/JAWS/server: Complete rewrite of JAWS. The new JAWS has
          support for Asynch-Thread-Pool (on WIN32), Synch-Thread-Pool,
          and Thread-per-Request. Different models can be configured using
          the svc.conf file.  The server now supports both GET and PUT
          commands.
          
          The HTTP_Handler class is a state based implementation of the
          HTTP protocol. Therefore, it can be used synchronously and
          asynchronously. It uses an abstract IO class to move between
          different HTTP protocol states. It is up to the IO class to
          decide on synchronous or asynchronous I/O.

        * apps/JAWS/client: This is an example of the implementation of
          BlobStreaming in ACE. This version of BlobStreaming uses HTTP as
          a transport protocol. 

          Blobby :-) is a simple application written using the ACE_Blob
          class, which is capable of doing both file uploads and
          downloads.  If a file is downloaded, the downloaded data is sent
          to standard output, so that it can be piped as necessary.

        * ace/Mem_Map.cpp (map_it): This method now uses ACE_OS::pwrite
          (if ACE_HAD_P_READ_WRITE is defined) instead of
          ACE_OS::lseek/ACE_OS::write to write the end-of-file byte. The
          old scheme does not work if the file is in OVERLAPPED mode.

        * ace/OS: Added pread and pwrite to the OS class (if
          ACE_HAD_P_READ_WRITE is defined). On Win32, these functions use
          the OVERLAPPED structure to specify the offset. This
          implementation will block until the write/read completes (even
          if the file is in OVERLAPPED mode).

        * ace/config: Added ACE_HAS_P_READ_WRITE to the following
          platforms that support pread() and pwrite() calls:
          config-sunos4-g++.h 
          config-sunos4-lucid3.2.h
          config-sunos4-sun3.x.h 
          config-sunos4-sun4.1.4.h
          config-sunos4-sun4.x-orbix.h 
          config-sunos4-sun4.x.h
          config-sunos5.4-centerline-2.x.h 
          config-sunos5.4-g++.h
          config-sunos5.4-sunc++-4.x-orbix.h
          config-sunos5.4-sunc++-4.x.h 
          config-sunos5.5-g++.h
          config-sunos5.5-sunc++-4.1.h  
          config-sunos5.5-sunc++-4.x-orbix.h
          config-sunos5.5-sunc++-4.x.h 
          config-sunx86-sunc++-4.x.h
          config-win32-common.h

Sun Apr  6 14:16:18 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * tests/Timer_Queue_Test.cpp: Added tests to make sure that the
          new ACE_Timer_Queue::cancel() logic is working correctly.  So
          far, it seems to be fine.

        * ace/Timer_{Heap,List}.cpp (cancel): Changed the comparison for
          dont_call_handle_close to be correct.

        * ace/OS.cpp: Deleted a useless return.  Thanks to Gonzalo
          A. Diethelm <gonzo@ing.puc.cl> for reporting this.

        * ace/config-irix6.2-sgic++.h: Added the following definitions:

          + ACE_LACKS_PTHREAD_THR_SIGSETMASK
          + ACE_HAS_PTHREAD_EQUAL
          + ACE_HAS_PTHREAD_T
          + ACE_HAS_SYSENT_H
          + ACE_HAS_SYSINFO
          + ACE_HAS_TEMPLATE_TYPEDEFS

          Deleted the following definitions:

          + #define ACE_HAS_SYS_SIGLIST (Irix's compiler only has a
            _sys_siglist array when compiling their own internal
            functions).

          Thanks to Gonzalo A. Diethelm <gonzo@ing.puc.cl> for this.

        * ace/Process: Added new support for setting the environment
          variable and the current working directory.  Thanks to Gonzalo
          A. Diethelm <gonzo@ing.puc.cl> for this enhancement.

        * ace/OS.h: "sys/stat.h" was being included more than once, so I
          fixed this.  Thanks to Gonzalo A. Diethelm <gonzo@ing.puc.cl>
          for reporting this.

        * ace/XtReactor.cpp: Added the register_handler_i() method, which
          just delegates to the one defined in the Reactor.  This is
          necessary to adjust to the C++ type system rules.  Thanks to
          Gonzalo A. Diethelm <gonzo@ing.puc.cl> for reporting this.

        * ace/Service_Config.cpp: Added the Double-Checked Locking
          Optimization pattern to all the ACE_Service_Config Singletons
          (e.g., thr_mgr(), reactor(), etc.) so that they behave correctly
          in multi-threaded programs.  Thanks to Matthias Kerkhoff
          <make@cs.tu-berlin.de> for insisting on this.

        * ace/OS.i (nanosleep): If the nanosleep() system call isn't
          supported by the OS platform we'll just use ACE_OS::sleep(const
          ACE_Time_Value &) instead.

        * ace/Log_Msg.cpp: Changed the logic of
          ACE_Log_Msg_Manager::remove() so that it returns the number of
          remaining registered instances.  When this goes to 0 we'll
          cleanup.

        * ace/OS.i: Enhanced the ACE_OS::cond_[timed_]wait() methods so
          that they use SignalObjectAndWait() whenever possible to avoid
          potential problems with unfairness.  See
          http://www.cs.wustl.edu/~schmidt/editorial-15.html for more
          details.  Thanks to David Holmes <ltdholmes@mri.mq.edu.au> for
          pointing out this subtlety.

Sun Apr 06 20:01:57 1997  David L. Levine  <levine@cs.wustl.edu>

        * include/makeinclude/wrapper_macros.GNU: added "purify" and
          "quantify" make command options.  To build Purified versions
          of all executables in the current direction, for example:

                % make clean; make purify=1

          These options assume that purify or quantify are in your PATH.

        * ace/Task.{h,cpp}: removed ACE_LACKS_STATIC_DATA_MEMBER_TEMPLATES
          from ACE_Task_Exit declaration and ACE_Task_Exit::instance ().
          ACE_Task_Exit is no longer a template class, so we don't need that.

        * ace/Task_T.h: added missing "*/" at end of comment after #endif.

        * tests/IOStream.cpp (server): added check for 0 strlen of
          "buf" to avoid out-of-bound array reference.

        * ace/Svc_Conf_l.cpp, Makefile: added #define ACE_BUILD_DLL.
          Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de> for
          reporting this.

        * ace/Set.cpp(ACE_Set_Node ctor): commented out unused arg MS_SUCKS.

Sat Apr  5 14:21:29 1997  Prashant Jain  <pjain@merengue.cs.wustl.edu>

        * java/: Changed package name from ACE to JACE across all directories.

Sat Apr  5 13:12:37 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * tests/MM_Shared_Memory_Test.cpp: Removed the use of dynamic
          memory allocation to avoid memory leaks.

        * ace/Service_Config: Changed _defaults to _static_svcs since this
          more accurately reflects what they do.

        * examples/Shared_Malloc/test_malloc.cpp: Removed the
          print_stats() call since it doesn't work via this API.  Thanks
          to Sandro Doro <alex@aureus.sublink.org> for reporting this.

        * ACE-install.sh: Tweeked the install script by changing the
          "gunzip; tar; gzip" sequence into "gunzip -c | tar xvf -" to
          speed it up a little.  Thanks to Per Andersson
          <Per.Andersson@hfera.ericsson.se> for this fix.

        * examples/Threads/future1.cpp: Make sure to delete the char *name
          that is retrieved from the future in order to avoid a memory
          leak.  Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de> for
          figuring this out.
        
        * examples/Threads/future1.cpp: Make sure to delete this->name_ in
          the Scheduler destructor to avoid a memory leak.

        * examples/Threads/task_four.cpp (close): Enhanced the close()
          method so that it will actually delete the memory for the
          Worker_Task.

        * ace/XtReactor.cpp (register_handler_i): Added the 

          if (mask & ACE_Event_Handler::ACCEPT_MASK)
            ACE_SET_BITS (condition, XtInputReadMask);

          Thanks to Jean-Marc Strauss <strauss@club-internet.fr> for
          reporting this.

        * ace/Timer_Queue.cpp (expire): This is the only method that calls
          ACE_Timer_Queue::cancel() with dont_call_handle_close set to 0.

        * ace/Reactor: Modified the cancel_timer() methods so that they
          also take a dont_call_handle_close parameter and pass it on to
          the Timer_Queue::cancel() method.

        * ace/Timer_{List,Heap}.cpp: Modified all the cancel() methods so
          that they will not call handle_close() unless the new parameter
          dont_call_handle_close is 0 (it is 1 by default).  This will
          avoid nasty problems with recursion.  Thanks to Paul Han
          <phan@CCGATE.HAC.COM> for suggesting this.

        * ace/Timer_{List,Heap}.cpp (schedule): If a user tried to
          schedule a NULL ACE_Event_Handler then we return -1 with errno
          set to EINVAL.

        * ace/Message_Block.cpp: Somehow the file got screwed up and was
          reverted back to an earlier incarnation where we didn't use
          ACE_Service_Config::alloc()...  Thanks to Matthias Kerkhoff
          <make@cs.tu-berlin.de> for figuring this out.

Sat Apr  5 19:11:46 1997  Tim H. Harrison  <harrison@waltz.cs.wustl.edu>

        * ace/Signal.i (ACE_Sig_Guard): Changed the constructor of
          ACE_Sig_Guard so that it doesn't call ACE_OS::sigprocmask for
          Win32.  This keeps errno from being set to ENOSYS at random
          times.

Sat Apr 05 17:27:02 1997    <irfan@TWOSTEP>

        * Registry.cpp (resolve): Type and size of the object is only set
          if RegQueryValueEx() returns success. Thanks to Alan
          (Alan_Cabrera@fp.cibc.com) for reporting this.

Sat Apr 05 13:11:04 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Log_Msg.cpp (instance): Added another ACE_NO_HEAP_CHECK.
          Matthias provided the fix.

        * ace/config-win32.h: Disable ACE_HAS_STRICT by default, because
          it will break existing application code.

        * ace/OS.{h,cpp},Log_Msg.{h,cpp}: fixes from Matthias Kerkhoff
          <make@cs.tu-berlin.de> to avoid memory-leak reports when MFC
          or (the CrtHeapXXX()-functions of the Win32 runtime library)
          are used.

          The problem is, that MFC (and so may other Win32 applications
          do) allocates a thread specific storage slot for each running
          thread which contains various control and debug informations.
          Part of this information is an object, which when constructed
          makes a snapshop of the heap. When this object is destroyed,
          the snapshot is compared to the actual heap. All object still
          existing on the heap are reported as memory leaks (which
          is in most situations correct).  Because the object is deleted
          when the thread (or programs main) is left and this happens
          before atexit is called, some leak reports are false (because,
          e.g., all these ACE_Log_Msg's will be deleted in atexit).

          The fix for ACE_Log_Msg consists of three changes (two only
          relevant for Win32, one relevant for all platforms.)
          Description of changes:

          a) Introduced a new macro ACE_NO_HEAP_CHECK, which turns
          off the built in heap checking until the current code block
          is left. (defined for all platforms, but only does something
          for Win32). This changes os.h and config-win32-common.h.

          b) Added a static member function to ACE_Log_Msg. The function
          (exists) returns 0 if the calling thread don't have an ACE_Log_Msg
          and non-null if an ACE_Log_Msg exists. This changes Log_Msg.h
          and Log_Msg.cpp.

          c) Changed ACE_Thread_Adapter in a way that creating a new
          thread does not automatically create an ACE_Log_Msg for the
          calling thread. This happened until now, because the new
          thread inherited the log settings of the calling thread.
          This behaviour makes no sense, if the calling thread does
          not have an ACE_Log_Msg, so i use ACE_Log_Msg::exists() (see
          above) to prevent the implicit creation of an ACE_Log_Msg
          for the calling thread.

          Thanks, Matthias!

        * ace/config-win32.h and config-win32-common.h: new, consolidated
          Win32 config files.  Thanks, again, Matthias!

        * ace/OS.h (ACE_UNUSED_ARG): determine whether we're building
          on an Irix platform by looking for ACE_HAS_IRIX_GETTIMEOFDAY
          instead of ACE_HAS_IRIX62_THREADS.

        * ace/Log_Msg.cpp: VxWorks (only!) change: no longer strdups
          program_name and local_host to avoid memory leaks.  Instead,
          the addresses of these are copied by ACE_Log_Msg.  So, only
          strings in the text segment should be passed to its functions!
          Again, this change is for VxWorks only.

        * ace/Sched_Params.cpp: moved memsets of pcinfo so that entire
          pcinfo structure is zeroed out, to _really_ avoid Purify warnings.

Fri Apr 04 12:28:40 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-mvs.h: removed ACE_HAS_IP_MULTICAST because MVS
          doesn't define ip_mreq.  Thanks to Chuck Gehr
          <gehr@sweng.stortek.com> for reporting this.

        * ace/OS.i (mutex_init): fixed the extra braces once and for all.
          Thanks to Chuck Gehr <gehr@sweng.stortek.com> for reporting it.

        * ace/OS.i, config-sco-5.0.0*.h: fixed for SCO so that it uses
          single-argument gettimeofday () prototype, but calls two-arg
          (SVR4) version in ACE_OS::gettimeofday ().  Thanks to Ganesh
          Ganesh Pai <gpai@voicetek.com> for solving this problem.

        * ace/Log_Msg.{h,cpp}: added ACE_Log_Msg destructor.  In
          instance (), added call to ::atexit () (::taskDeleteHookAdd ()
          on VxWorks) to register cleanup handler.  Each new instance
          of an ACE_Log_Msg is inserted into an ACE_Unbounded_Set; the
          cleanup handler iterates over the Set and deletes the
          ACE_Log_Msgs at program exit.  

          Also, the two strings that are allocated get cleaned up after
          the last ACE_Log_Msg instance is deleted.  Many thanks to
          Matthias Kerkhoff <make@cs.tu-berlin.de> for figuring this out
          and cranking out the code.

          It works differently on VxWorks, because it doesn't have
          ::atexit ().  VxWorks has ::taskDeleteHookAdd (), which is
          called when each task exits.  So, the Set isn't used.  Instead,
          the cleanup hook is called for each task when it exits, passing
          the task control block (TCB) of the exiting task.  A pointer to
          the ACE_Log_Msg instance is contained in one of the spare fields
          of the TCB, so the cleanup handler simply deletes it.

        * ace/IOStream.h: specify template parameter (ACE_IOStream<STREAM>)
          to ACE_OPERATOR{G,P}_SET macros.  Thanks to Chuck Gehr
          <gehr@sweng.stortek.com> for providing this fix.

Thu Apr  3 22:17:53 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/Registry.cpp: Changed STRING_SEPARATOR from Istring to
          LPCTSTR.  Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de> for
          suggesting this.

Thu Apr  3 21:39:45 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/OS.i (mutex_init): Removed errant open-brace ('{').  Thanks
          to Chuck Gehr (gehr@sweng.stortek.com) for the fix!

Thu Apr 03 08:52:34 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h,OS.cpp,Sched_Params.cpp: added /**/ to some #include
          directives.  Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de>
          for reporting these.

        * ace/OS.cpp (writev, readv): changed type of local variable "i"
          from size_t to int to avoid signed/unsigned mismatch.  Thanks
          to Matthias Kerkhoff <make@cs.tu-berlin.de> for reporting this.

        * ace/OS.cpp (readv), SOCK_Dgram.cpp (recv): added casts of
          iov_len and copyn because iov_len is int on some platforms and
          size_t on others.  This avoids compiler (MSVC 4.1) warnings.
          Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de> for reporting
          this.

        * include/makeinclude/platform_sco5.0.0-nothread.GNU:
          updated CCFLAGS and added LD=$(CXX).   Thanks to
          Ganesh Pai <gpai@voicetek.com> for these fixes.

        * ace/OS.h: added #include of <sys/regset.h> for SCO only.
          Thanks to Ganesh Pai <gpai@voicetek.com> for this fix.

        * ace/config-sco-5.0.0*.h: added #define ACE_HAS_IP_MULTICAST.
          Thanks to Ganesh Pai <gpai@voicetek.com> for this fix.

        * ace/config-{chorus,linux*,sco*}.h: removed #define of
          ACE_HAS_INLINED_OSCALLS because it's no longer needed in the
          config files:  it's #defined in OS.h if needed.

Thu Apr  3 01:48:01 1997  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

        * ace/Malloc.i (malloc): ACE_New_Allocator::malloc only calls new
          if nbytes is > 0.  Purify was complaining that 0 bytes were
          allocated but never deleted.  Go figure.

Wed Apr  2 22:24:48 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.cpp: Moved the ACE_OS::inet_aton() method into the *.cpp
          file and made it non-inline to work around a bug with HP/UX C++.
          Thanks to Neil Cohen for this fix.

Wed Apr 02 10:09:37 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-sunos5.5-sunc++-4.1.h: added template specialization
          with Sun C++ 4.2.

        * include/makeinclude/platform_sunos5_sunc++_4.1.GNU: removed +w
          and added comments about Sun C++ 4.2 support.

        * include/makeinclude/platform_chorus.GNU, platform_hpux_gcc.GNU,
          platform_irix5.{2,3_g++}.GNU, platform_linux{_,pthread}.GNU,
          platform_m88k.GNU,platform_osf1_4.0_g++.GNU,
          platform_sco-nothread.GNU,platform_sco5.0.0-*.GNU,
          platform_sunos{4,5}_g++.GNU, platform_sunos5_x86_g++.GNU,
          platform_unixware_g++.GNU, platform_vxworks5.2_g++.GNU:
          added -fno-implicit-templates to CCFLAGS.  See INSTALL file
          for discussion of the g++ option.  Also, added -O2 because
          it dramatically reduces object file sizes.

        * netsvcs/clients/Tokens/manual/manual.cpp: made
          STDIN_Token::TID typedef public so that template
          specialization (w/ Sun C++ 4.2) can access it.

Wed Apr  2 10:02:47 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/OS.h: Added definitions for THREAD- and PROCESS-LEVEL
          priorities because some implementations define these while
          others don't.  These are now
          ACE_{THR,PROC}_{FIFO,RR,OTHER}_{MIN,MAX,DEF}.  The only really
          NEW concept is the *_DEF, which is a default value assigned by
          ACE_OS::thr_create() if one isn't given.  Of special note is that
          we don't redefine a default values if it's already been
          defined, which allows individual programs to have their
          own ACE-wide "default".

        * ace/OS.cpp (thr_create): Uses ACE_{THR,PROC}_* macros
          rather than the PRI_* macros.

        * ace/Sched_Params.cpp (priority_min,priority_max): These now
          use ACE_{THR,PROC}_* macros to ignore OS-specific priority
          assignments.

        * ace/config-linux-lxpthreads.h: Removed definitions of
          PRI_{FIFO,RR,OTHER}_{MIN,MAX}.

        * include/makeinclude/platform_linux*.GNU (CCFLAGS): Added
          -fno-implicit-templates now that it's supported.  This
          eliminates messages of the sort 'ld: Warning size of
          <mangled template specialization name> change from xx to yy'
          when linking libACE.so.  Thanks to David Levine for making
          this possible!
        
Tue Apr  1 15:27:28 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * bin/g++dep: Removed the "/bin" prefix so that this won't fail on
          platforms that don't have sed in /bin.  Thanks to Sandro Doro
          <alex@aureus.sublink.org> for this fix.

Tue Apr 01 09:55:07 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: protected definition of struct flock on VxWorks,
          because it defines that type in sys/fcntlcom.h.  (It doesn't
          appear to support flock (), though.)  Thanks to Dave
          Mayerhoefer <mayerhoefer@svappl36.mdc.com> for reporting this.

        * ace/OS.h: define ACE_hrtime_t as u_longlong_t gcc, because
          its long long types are only 4 bytes long.  Its longlong_t
          types are 8 bytes.  Also made ACE_hrtime_t unsigned for
          other than gcc on Unix platforms.

        * ace/OS.* (gethrtime), config-vxworks-ghs-1.8.h: added support
          for PowerPC with Green Hills compiler.  Thanks to Dave
          Mayerhoefer <mayerhoefer@svappl36.mdc.com> for providing the
          readPPCTimeBase assembler routine.

        * ace/config-vxworks*.h: removed #include of vxWorks.h because
          its no longer necessary with the TimeValue.h merged into OS.h.

        * ace/High_Res_Timer.cpp (elapsed_time): added cast to
          initialization of nseconds to avoid compiler warning from
          MSVC 4.1 about narrowing from unsigned __int64.
          Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de> for
          reporting this.

Mon Mar 31 18:18:35 1997  Carlos O'Ryan  <coryan@charlie>

        * ace/config-hpux-10.x-g++.h: 
        It was tuned to HP-UX 10.10 (and further) using g++ 2.7.2 without
        DCE/Threads.

        * ace/Task_T.cpp: 
        Another iteration on the Module.h file, this time it is not
        included *only* under HPUX and when using HP/aCC. Still IMHO
        problems will arise as template sintax checking becomes more
        popular.

        * ace/Local_Name_Space_T.h: 
        * ace/Local_Name_Space_T.cpp: 
        Replaced MAXNAMELEN with MAXPATHLEN since some platforms
        (e.g., HP/UX) have a very low value (e.g., 14 bytes) for
        MAXNAMELEN.

        * ace/config-hpux-10.x-aCC.h: 
        The comment did not make clear what was compiler/platform
        target. It also included some remarks that only applied to
        HP/C++.

        * tests/Future_Test.cpp: 
        * tests/Message_Block_Test.cpp: 
        * tests/Thread_Pool_Test.cpp: 
        Will not compile if ACE_HAS_THREADS was not defined and
        ACE_TEMPLATES_REQUIRE_SPECIALIZATION was: they tried to
        instantiate templates that were only defined when ACE_HAS_THREADS.

        * ace/config-hpux-10.x-aCC.h: 
        More fine tuning: ACE_HAS_EXCEPTIONS,
        ACE_LACKS_LINEBUFFERED_STREAMBUF,
        ACE_HAS_STREAM_PIPES.

        * ace/TLI_Stream.h: 
        * ace/TLI_Acceptor.h: 
        No "Meta-type info" was defined (the PEER_ADDR and PEER_STREAM
        typedefs).

        * ace/Signal.h: 
        * ace/Signal.cpp: 
        With HP/aCC we can enable ACE_Sig_Handlers.

Mon Mar 31 22:36:55 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Service_Config.cpp (process_directives): Return -1 if
          ace_yyerrno > 0.  Thanks to Alan Cabrera
          <Alan_Cabrera@fp.cibc.com> for reporting this.

Mon Mar 31 17:38:08 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/OS.cpp (thr_create): Moved priority determination after
          policy determination because it's possible for setting of the
          priority to fail if it's not a valid priority for the [default]
          policy.

Mon Mar 31 09:00:54 1997  David L. Levine  <levine@cs.wustl.edu>

        * performance-tests/Misc/context_switch_time.cpp: this test no
          longer worked.  So, reverted to revision 4.5, plus minimum
          changes necessary to support build on platforms without threads.

        * examples/Threads/Makefile, performance-tests/Misc/Makefile:
          moved context_switch_time.cpp from examples/Threads to
          performance-tests/Misc.

        * examples/Logger/Acceptor-server/server_loggerd.cpp,
          examples/Reactor/Misc/pingpong.cpp,
          examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp,
          examples/Shared_Malloc/Malloc.cpp:
          added template specializations.

        * include/makeinclude/platform_sunos5_g++.GNU: removed dependency
          of CCFLAGS on CFLAGS to avoid duplicate -g in build command.
          Also, added -fno-implicit-templates in comment.

Sun Mar 30 12:52:58 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Malloc.h: The block begining with:
          #if defined (ACE_MALLOC_STATS)
          and ending with end of struct ACE_Malloc_Stats
          must be moved (up) after line 107

          Thanks to Sandro Doro <alex@aureus.sublink.org> for pointing
          this out.

        * ace/Malloc_T.cpp: The line
          this->malloc_stats_.dump ();
          must be changed in:
          this->cb_ptr_->malloc_stats_.dump ();

          Thanks to Sandro Doro <alex@aureus.sublink.org> for pointing
          this out.

        * ace/Malloc_T.cpp: the line
          this->cb_ptr_->malloc_stats_.print ();    // print not exists
          may be changed in:
          this->cb_ptr_->malloc_stats_.dump ();

          Thanks to Sandro Doro <alex@aureus.sublink.org> for pointing
          this out.

        * ace/Malloc_T.h: Added "virtual" to the ACE_New_Allocator methods
          to reinforce the fact that they are indeed virtual.  Thanks to
          Sandro Doro <alex@aureus.sublink.org> for pointing this out.

        * ace/Malloc.h: Added "virtual" to the ACE_New_Allocator methods
          to reinforce the fact that they are indeed virtual.

Sat Mar 29 20:26:54 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: moved #defin of RTLD_LAZY after #include of dlfcn.h.
          Thanks to Chris Lahey <CLahey@cccis.com> for this fix.

        * ace/Task_T.h: replaced #include of "ace/Module.h" because some
          Task_T methods use ACE_Module methods.

        * examples/Connection/non_blocking/test_{sock,spipe,tli}_{acceptor,
          connector}.cpp,
          examples/System_V_IPC/SV_Semaphores/Semaphores_{1,2}.cpp:
          added template specializations.

Sat Mar 29 17:08:33 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/OS.cpp: Added many new ACE_UNUSED_ARGS macros to eliminate
          warnings when we are compiling without threads.

Fri Mar 28 11:34:38 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Task.{h,cpp},Thread_Manager.h: changed remaining
          priority types to long and defaults to -1.

        * ace/Thread_Manager.cpp (spawn_i): don't clobber errno!
          ACE_OS::thr_create () sets errno and returns -1.  So,
          its return value should not be used to set errno.

        * ace/OS.cpp (thr_create): fixed PTHREADS_1003_DOT_1C thread
          priority logic.  Thanks to Thilo Kielmann
          <kielmann@informatik.uni-siegen.de> for the patch.

        * ace/config-sunos5.5*.h,README,OS.cpp (thr_create): added
          ACE_HAS_ONLY_SCHED_OTHER to indicate that platform (Solaris 2.5)
          only supports POSIX SCHED_OTHER scheduling policy.

        * tests/Priority_Task_Test.cpp (open): added THR_SCHED_FIFO flag.
          Thanks to Thilo Kielmann <kielmann@informatik.uni-siegen.de> for
          for this suggestion.

        * examples/ASX/Event_Server/Event_Server/Makefile,
                                    Transceiver/Makefile:
          added -lGateway to LIBS to pick up its template
          instantiations during links.

        * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp,
                                    Transceiver/transceiver.cpp,
                   Connection/blocking/SPIPE-{acceptor,connector}.cpp,
                              misc/Connection_Handler.cpp,test_upipe.cpp,
                   Logger/simple-server/server_loggerd.cpp,
                   UPIPE_Event_Server/{Consumer,Supplier}_Router.cpp,
                   performance-tests/Synch-Benchmarks/Options.cpp:
          added template specializations.

Thu Mar 27 21:10:59 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/IOStream.h: only use built-in ipfx{0,1} () with __GNUC__,
          because that's the only compiler we know of that has them.
          Thanks to Carlos O'Ryan <coryan@mat.puc.cl> for pointing this
          out, and to James CE Johnson <jcej@lads.com> for providing the fix.

        * ace/OS.i: rearranged order of ACE_Time_Value functions (moved
          set ()'s up, moved arithmetic operators down) so that they are
          defined before use.

        * ace/Task_T.cpp: removed ACE_TEMPLATES_REQUIRE_SOURCE around
          #include of "ace/Module.h" so that it will build with Sun C++ 4.1.

        * apps/Gateway/Peer/Makefile: added -lGateway to LIBS to
          pick up its template instantiations during links.

        * apps/Gateway/Peer/Peer.cpp: added template instantations.

Thu Mar 27 14:10:39 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/OS.h: Added two new accessors to ACE_Time_Value:

          operator timeval *() const;
          // Returns a pointer to the object as a timeval.

          const operator timeval *() const;
          // Returns a pointer to the object as a timeval.

          Thanks to Carlos O'Ryan <coryan@mat.puc.cl> for this suggestion.

        * ace/OS.i (ACE_Time_Value): Inlined many of the ACE_Time_Value
          accessors.

        * ace/OS.h: Reimplemented ACE_Str_Buf at 

          struct ACE_Export ACE_Str_Buf : public strbuf
          {
            // = Initialization method
            ACE_Str_Buf(void* b = 0, int l = 0, int max = 0);
            // Constructor.
          };
 
          this makes the casting from ACE_Str_Buf* to strbuf* a "safe"
          cast and makes it more portable (say on platforms where the
          fields in strbuf are not in the right order).  Thanks to Carlos
          O'Ryan <coryan@mat.puc.cl> for this fix.

        * ace/OS.h: Moved the definition of imr_multiaddr to just before
          class ACE_OS so that it picks everything up appropriately.
          Thanks to Hakan Kallberg <hk@simulina.se> for reporting this.

        * ace/config-aix-4.[12].x.h and config-mvs.h: Fixed the
          ACE_HAS_MULTICAST macros, which should have said
          ACE_HAS_IP_MULTICAST.  Thanks to Daniel Montalibet
          <daniel_montalibet@stortek.com> for reporting this.

Thu Mar 27 15:54:10 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/{Thread,Thread_Manager}.{h,i,cpp} (ACE_Thread): Changed
          type for priority arg to spawn*() from u_int to long to
          support changes in thr_create indicated below.  Thanks to
          Thilo Kielmann <kielmann@informatik.uni-siegen.de> for these
          changes.

        * ace/OS.cpp: Ensure that whenever either a priority of a
          scheduling policy is set explicitly, with POSIX threads, the
          other argument and the flag THR_EXPLICIT_SCHED is set
          automatically.  A range check for priority values for POSIX
          1003.1c is also included.  Thanks to Thilo Kielmann
          <kielmann@informatik.uni-siegen.de> for these changes.

        * ace/OS.h: Changed type and default value of priority arg to 
          thr_create from u_int to long and 0 to -1.  Thanks to Thilo 
          Kielmann <kielmann@informatik.uni-siegen.de> for these
          changes.  Also added ACE_MAX and ACE_MIN macros.

Thu Mar 27 11:25:38 1997  David L. Levine  <levine@cs.wustl.edu>

        * netsvcs/servers/Makefile: removed SHOBJ so that main.so is not
          built, because it wasn't needed.  Thanks to Sandro Doro
          <alex@aureus.sublink.org> for this fix.

        * ace/config-aix-4.[12].x.h,config-mvs.h: changed
          ACE_HAS_MULTICAST to ACE_HAS_IP_MULTICAST.  Thanks to Daniel
          Montalibet <daniel_montalibet@stortek.com> for reporting
          this. 

        * include/makeinclude/platform_sunos5_g++.GNU,
                              platform_sunos5_x86_g++.GNU,
                              platform_unixware_g++.GNU:
          removed "-L$(WRAPPER_ROOT)/ace -L./" from LDFLAGS because it
          is added to LDFLAGS in include/makeinclude/wrapper_macros.GNU.

        * apps/Gateway/Gateway/{Event_Channel.cpp,Gateway.cpp,
                                Proxy_Handler.cpp,Proxy_Handler_Acceptor.cpp,
                                Proxy_Handler_Connector.cpp,
          examples/IPC_SAP/UPIPE_SAP/ex{2,3}.cpp,
          netsvcs/clients/Naming/Client/Client_Test.cpp,
          netsvcs/clients/Tokens/manual/manual.cpp:
          added template specializations.

Thu Mar 27 10:05:59 1997  Prashant Jain  <pjain@merengue.cs.wustl.edu>

        * netsvcs/lib/TS_Clerk_Handler.cpp: Fixed two things:
          1) In TS_Clerk_Processor::parse_args() changed
          "%n:\n[-p hostname:port] [-t timeout] [-p poolname]\n%a", 1),
          to
          "%n:\n[-h hostname:port] [-t timeout] [-p poolname]\n%a", 1),

          2) In TS_Clerk_Processor::alloc() changed
          void *temp = 0;
          // Only create the state if it doesn't already exist.
          if (this->shmem_->find (ACE_DEFAULT_TIME_SERVER_STR, temp) ==  -1)
          {
            // Allocate the space out of shared memory for the system time entry
            temp = this->shmem_->malloc (sizeof (this->system_time_));
 
          to:
 
          // Only create the state if it doesn't already exist.
          if (this->shmem_->find (ACE_DEFAULT_TIME_SERVER_STR) ==  -1)
          {
            // Allocate the space out of shared memory for the system time entry
            void *temp = this->shmem_->malloc (sizeof (this->system_time_));
 
          Thanks to Sandro Doro (alex@aureus.sublink.org) for suggesting these changes.

Thu Mar 27 01:00:18 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * include/makeinclude/platform_irix6.2_sgiCC.GNU: Added a new
          platform config file for SGI Irix 6.2 using the CC compiler (not
          NCC nor the MipsProcompiler).  Thanks to Eric Dean Russell
          <edrusse@somnet.sandia.gov> for these changes.

        * ace/OS.h: Moved the ACE_LACKS_UTSNAME_T block into the right
          part of the code.  Thanks to Jonathan Biggar <jon@sems.com> for
          this fix.

        * ace/Malloc.h: Added an enhancement so that the new alignment
          features will work regardless of the size of ACE_MALLOC_ALIGN.
          Thanks to Fred LaBar <flabar@fallschurch.esys.com> for this fix.

        * ace/Synch_Options.cpp: We now automatically set the USE_TIMEOUT
          flag if a non-0 timeout value is supplied.  Thanks to Tim
          Liddelow <tim@cst.com.au> for this suggestion.

Wed Mar 26 08:47:24 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/{ACE.cpp,Log_Msg.cppOS.cpp},
          tests/{Message_Queue_Test.cpp,Naming_Test.cpp}:
          Changed ::sprintf calls to ACE_OS::sprintf.  Thanks to
          Thilo Kielmann <kielmann@informatik.uni-siegen.de> for
          reporting this.

        * netsvcs/lib/{Client_Logging_Handler.cpp,Name_Handler.cpp,
                       Server_Logging_Handler.cpp,TS_Service_Handler.cpp,
                       Token_Handler.cpp}: added template specializations.

Tue Mar 25 06:47:14 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.h: Moved config.h to the top of OS.h so that we don't
          have to worry about not defining things in the right place.
          Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de> for pointing
          this out.

Tue Mar 25 22:54:49 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/OS.i: Added UNICODE support for ACE_OS::chdir().  Thanks to
          Ivan Murphy <Ivan.Murphy@med.siemens.de> for the code.

Tue Mar 25 21:26:10 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/TTY_IO.{h,cpp},README, and these config files:
          config-aix-*.h, config-hpux-*.h, config-irix5.*.h,
          config-mvs.h, config-osf1-*.h, config-sun*.h (except for g++
          and config-sunos5.5-sunc++-4.1.h), config-win*.h:
          Added ACE_NEEDS_DEV_IO_CONVERSION to conditionally compile the
          ACE_DEV_IO & conversion operator for ACE_TTY_IO, which is a
          subclass of ACE_DEV_IO.  Thanks to Fred LaBar
          <flabar@fallschurch.esys.com> and Gonzalo Diethelm
          <gonzo@ing.puc.cl> for reporting warnings without this on
          Irix 6.2 with the mipsPro compiler.

        * ace/OS.cpp (thr_create): on VxWorks, always pass 0 as first arg to
          ::taskSpawn () so that VxWorks will generate the task ID.
          Thanks to Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com>
          for providing this fix, without which random task names would
          be assigned.

        * ace/ACE.cpp (get_bcast_addr): added return 0 at end of non-WIN32
          code to avoid compile warning from g++.

        * tests/IOStream_Test.cpp: removed extra "(%P|%t)" from output.
          I couldn't get ACE_ERROR_RETURN to work on g++:  it complained
          about mismatched return types when returning an int from a
          function that returns a void *, and about mismatched arguments
          to an ACE_Log_Msg function if I cast the int to a void *.  So,
          I used ACE_ERROR instead.
          Added ACE_UNUNSED_ARG (arg).  Removed unused variables
          error_at_server and error_at_client.

        * netsvcs/lib/TS_Clerk_Handler.cpp: added another template
          specialization.

        * examples/Reactor/Multicast/client.cpp: Log_Wrapper::LOG_DEBUG
          instead of LM_DEBUG.

        * examples/Threads/context_switch_time.cpp: use ACE_Sched_Params
          to get platform-dependent thread priorities.  Also, moved #includes
          so that config.h is read before testing for ACE_HAS_THREADS.

        * examples/Threads/{auto_event.cpp,barrier2.cpp,future1.cpp,
                            future2.cpp,reader_writer.cpp,tss1.cpp,tss2.cpp}:
          added template specializations.

Tue Mar 25 10:01:05 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * config-linux.h: Added
        ACE_HAS_{SVR4_DYNAMIC_LINKING,AUTOMATIC_INIT_FINI}.  Thanks to
        alex@aureus.sublink.org (Sandro Doro) for the change.

        * platform_linux.GNU: Added -ldl to LIBS.  Thanks to
        alex@aureus.sublink.org (Sandro Doro) for the change.

Tue Mar 25 16:01:34 1997  Carlos O'Ryan  <coryan@charlie>

        * ace/Svc_Handler.cpp: 
        I forgot to comment this: "operator delete" used to call ::delete
        on a void*, on ANSI/C++ this is not allowed. Since "operator new"
        calls ::new for a char[] I do a casting to char* and call
        ::delete[] on the char pointer.

        * ace/config-hpux-10.x-aCC.h: 
        HP-UX 10.10 supports CLOCK_GETTIME, my guess is that it should
        work with g++ and HP/C++, but I won't mess with those files yet.

        * ace/Connector.h: 
        The default address parameter for "connect" is a bit tricky, from
        the comments in the file:
          //
          // If the compiler supports 'typename' we cannot use
          // 
          // PEER_CONNECTOR::PEER_ADDR::sap_any
          // 
          // because PEER_CONNECTOR::PEER_ADDR is not considered a
          // type. But: 
          //
          // typename PEER_CONNECTOR::PEER_ADDR::sap_any
          // 
          // will not work either, because now we are declaring sap_any a
          // type, further:
          // 
          // (typename PEER_CONNECTOR::PEER_ADDR)::sap_any
          //
          // is considered a casting expression. All I can think of is
          // using a typedef, I tried PEER_ADDR but that was a source of
          // trouble on some platforms. I will try:
          //
          typedef ACE_PEER_CONNECTOR_ADDR ACE_PEER_ADDR_TYPEDEF;

        * ace/OS.h: 
        The stock HP C++ compiler (cfront based) gives lots of warnings in
        <net/if.h>. I used to define volatile to avoid this warnings. Now
        I think I'll rather like to see them.

        * ace/SPIPE_Stream.h: 
        * ace/SPIPE_Connector.h: 
        There was no meta-type info (PEER_ADDR) for SPIPE_Stream and
        SPIPE_Connector.

        * ace/Stream_Modules.h: 
        * ace/Stream_Modules.cpp: 
        Fixed a "bug" introduced in my last change: a couple of
        ACE_ALLOC_HOOK_* were commented but shouldn't.

        * examples/Connection/non-blocking/CPP-acceptor.cpp (open): 
        PR_AD cannot be used in this context, it expands to
        _ACE_PEER_ACCEPTOR::PEER_ADDR (via ACE_PEER_ACCEPTOR_ADDR), but
        the template parameter is _ACE_PEER_STREAM (aka PR_ST_1, aka
        ACE_PEER_STREAM_1).
        The right macro was ACE_PEER_STREAM_ADDR.

        * ace/Connector.h: 
        * ace/Connector.cpp: 
        The typedef trick I used (PEER_ADDR) did not work on every
        platform.
        I also broke some examples since ACE_PEER_CONNECTOR_ADDR did not
        include ACE_TYPENAME on its definition. Hopefully this new trick
        will work everywhere.

        * I finally sorted out the mistery of including "ace/Module.h"
        into "ace/Task_T.cpp": when compiling "ace/Stream_Modules.cpp" you
        get the following include sequence:
        Stream_Modules.cpp
          Stream_Modules.h
            Task.h
              Task.i
              Task_T.h
                Message_Queue.h (descendants removed)
                Synch_T.h (descendants removed)
                Task.h (already included).
                Task_T.i
                Task_T.cpp
                  Module.h
                    ACE.h (descendants removed)
                    Task.h (already included).
                    Module.i
                    Module.cpp

        At this point Module.cpp uses ACE_Thru_Task declared on
        Stream_Modules.h, but after the #include "ace/Task.h";
        in fact Module.cpp tries to #include "ace/Stream_Modules.cpp" but
        that second #include expands to nothing due to the canonical
        protection on Stream_Modules.h.
        That explains the removal of Module.h in Task_T.cpp.
        If you are wondering why so long an explanation for this change
        the answer is simple: just because I was curious on now it worked.

Mon Mar 24 14:08:48 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/SOCK_Dgram_Bcast.cpp (mk_broadcast): Cleaned up the code a
          bit.

        * ace/ACE: Added a new method called get_bcast_addr() which will
          get the broadcast address for a host.  Thanks to Paul Han
          <phan@CCGATE.HAC.COM> for suggesting this.

        * ace/UNIX_Addr: Added another set method in UNIX_Addr class:

          void set (const ACE_UNIX_Addr &sa);
          // Creates an ACE_UNIX_Addr from another <ACE_UNIX_Addr>.

          Thanks to Paul Han <phan@CCGATE.HAC.COM> for this.
          
        * ace/SOCK_Dgram: Removed the #if defined (ACE_HAS_IP_MULTICAST) 
          since this is now handled at the ACE_OS level.

        * ace/OS.h: Added support for IP multicast macros and structs even
          on platforms that don't support it so that the tests will
          compile without having lots of #ifdefs.

        * tests/Future_Test.cpp: Added a check for platforms that lack
          threads.  Thanks to Hakan Kallberg <hk@simulina.se>
          for reporting this.

        * netsvcs/lib/Server_Logging_Handler.cpp: Added a check for
          platforms that lack threads.  Thanks to Hakan Kallberg
          <hk@simulina.se> for reporting this.

        * examples/Threads/context_switch_time.cpp: Added an #ifdef for
          ACE_HAS_THREADS to this test so that it will compile on
          platforms that don't have threading.  Thanks to Scott Halstead
          <scott.halstead@gs.com> for reporting this.

        * tests/IOStream_Test.cpp: Fixed up this test so that it works
          correctly on platforms that lack multi-threading.  Thanks to
          Scott Halstead <scott.halstead@gs.com> for reporting this.

        * netsvcs/lib/Makefile: Reincluded the LIB target so that we'll
          build a static library.  Thanks to Scott Halstead
          <scott.halstead@gs.com> for reporting this.

        * ace/SOCK_Dgram.cpp (recv): Added a check to make sure that we
          don't try to copy more into the recv buffer than we've really
          got.  Thanks to Alan_Cabrera@fp.cibc.com for this fix.

        * ace/OS.cpp (readv): Added a check to make sure that we don't try
          to copy more into the recv buffer than we've really got.  Thanks
          to Alan_Cabrera@fp.cibc.com for this fix.

        * ace/Malloc.h: Modified the alignment strategy to define
          ACE_MALLOC_ALIGN to a number of bytes. (it gets rounded to a
          number of long's).  This makes it easier to work with more
          complex buffer alignment strategies (e.g., DMA).  Thanks to Fred
          LaBar <flabar@fallschurch.esys.com> for this.

        * ace/OS.cpp (readv): Added several more changes for the readv()
          emulation.  Thanks to Alan Cabrera <Alan_Cabrera@fp.cibc.com>
          and Adam Porter <aporter@cs.umd.edu> for these fixes.

Mon Mar 24 14:22:17 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.cpp (thr_create): For VxWorks, fixed call to ::taskSpawn ().
          ACE's arguments are in an array, not individual arguments.
          Also, set flags to VX_FP_TASK if it's 0, to match behavior
          of ::sp ().  Thanks to Dave Mayerhoefer
          <mayerhoefer@svappl36.mdc.com> for reporting these and providing
          the fix.

        * ace/High_Res_Timer.cpp (elapsed_time (struct timespec &):
          fixed, using same approach as in elapsed_time
          (ACE_hrtime_t &nanoseconds), to get nanosecond resolution.

        * netsvcs/lib/TS_Clerk_Handler.cpp (handle_close): added
          ACE_UNUSED_ARG (mask).  Also, added template specializations.

        * examples/Reactor/Multicast/server.cpp (Server_Events ctor):
          rearranged initializers to match declaration order.

        * examples/IOStream/server/iostream_server.cpp,
                            client/iostream_client.cpp:
          added template specializations.

Mon Mar 24 13:21:31 1997  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

        * ace/High_Res_Timer.cpp (elapsed_time): Added an
          ACE_High_Res_Timer::elapsed_time (ACE_hrtime_t &nanosecond)
          method that returns the number of elapsed nanoseconds.  This is
          accomplished even with the scale factors converting to
          microseconds.  It also does not use floating point
          calculations.

Sun Mar 23 13:25:39 1997  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

        * ace/High_Res_Timer.h: Removed <scale_factor> from the
          constructor of High_Res_Timer.  All High_Res_Timers now use
          global_scale_factor_ directly.  Hopefully, this will not break
          any existing code!

Sat Mar 22 12:06:22 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/OS.h: The include statement for config.h was too low.  Some
          defines for key_t, needed for NT, didn't work.  Thanks to Alan
          Cabrera <Alan_Cabrera@fp.cibc.com> for these fixes.

        * examples/Reactor/Multicast: Improved the multicast client and
          server programs to work better.

        * ace/Connector.cpp: Modified the ACE_Connector::handle_close()
          method to prevent recursive calls to itself.  Thanks to Paul Han
          <phan@CCGATE.HAC.COM> for reporting this.

        * ace/Svc_Handler.cpp: Put the check (closing_ == 0) in the
          destructor as well as in the destroy() method.  This prevents a
          possible core dump when the timer exists.  The instruction
          reactor::remove_handler in the shutdown method currently will be
          called twice when ACE_Svc_Handler object is being deleted.  Core
          dump occurs when it tries to execute ACE_Reactor::remove_handler
          method the second time because the ACE_Svc_Handler object
          pointer has already been deleted by the previous instruction
          ACE_Reactor::cancel_timer.  Thanks to Paul Han
          <phan@CCGATE.HAC.COM> for reporting this.

        * ace/OS.cpp: Added new thread-safe implementations of writev()
          and readv() for platforms that lack these functions.

        * ace/SOCK_Dgram.cpp: Added new implementations of
          ACE_SOCK_Dgram::{send,recv} that define methods for
          send(iovec[], ...)  and recv(iovec[], ...) for systems that
          don't have sendmsg() and recvmsg().  Thanks to Alan Cabrera
          <Alan_Cabrera@fp.cibc.com> for these fixes.

        * apps/jaws/HTTP_Handler.cpp: Removed some problematic template
          specializations that were left over from an earlier version of
          JAWS.  Thanks to Adam Porter <aporter@cs.umd.edu> for reporting
          this.

        * examples/Logger/Acceptor-server/server_loggerd.cpp: Revised the
          code to use the new ACE_Svc_Handler logic that checks to ensure
          that we don't recurse infinitely in handle_close().
          Thanks to Jean-Marc Strauss <strauss@club-internet.fr> for
          reporting this problem.

        * examples/Logger/simple-server/Logging_Handler.cpp
          (handle_close): Added a check to make sure we don't end up
          recursively calling handle_close().  This will prevent
          a segfault.

Sat Mar 22 07:30:49 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/High_Res_Timer.*: Changed scale factor to convert
          platform-dependent clock units to microseconds instead of
          nanoseconds.  That way, it should be greater than 1 for
          all supported platforms.  So, it's now an unsigned long
          instead of a double.

        * ace/OS.h: Changed ACE_hrtime_t to unsigned __int64 with
          _MSC_VER.  Also, fixed typo: "uint64" instead of "unit64"
          without _MSC_VER.

Fri Mar 21 08:37:34 1997  Carlos O'Ryan  <coryan@charlie>

        * makeinclude/rules.lib.GNU:
        I use the macro SOEXT to support HP non-standard extension for
        shared library names (.sl instead of .so).
        I also changed the rule to build shared libraries: under HP-UX you
        cannot pass extra libraries (-lXXX options) when building a shared
        lib. Before HP-UX 10.10 it wasn't a problem because no library was
        needed with ACE, but to support XLI the '-lxti' flag must be used
        on binaries (but not on shared libs).

        * include/makeinclude/platform_hpux.GNU: 
        The PIC option (+Z) was used always, clearly not intended.

        * include/makeinclude/platform_hpux_gcc.GNU: 
        Added a config file for g++ under HP-UX.

        * include/makeinclude/platform_hpux_aCC.GNU: 
        Added a config file for HP/aCC compiler under HP-UX.

        * ace/Makefile: 
        * netsvcs/lib/Makefile: 
        Changed to support the SOEXT macro.

        * config-hpux-10.x.h: 
        * config-hpux-10.x-aCC.h: 
        * config-hpux-10.x-g++.h: 
        I updated the files to HP-UX 10.10, AFAIK since that version HP-UX
        uses fd_set instead of int in select(2) (so ACE_SELECT_USES_INT is
        not needed) and the OS supports siginfo_t and ucontext_t so
        ACE_HAS_SIGINFO_T and ACE_HAS_UCONTEXT_T are defined.
        I *do not* have threads at my site nor the infamous PHSS_6246
        patch so I couldn't test the threaded version nor the HP cfront
        based one.
        ACE compiled fine with g++ and HP/aCC though.

        * ace/OS.h: 
        * ace/Malloc_T.h: 
        HP/aCC supports the typename keyword. I added a new config macro
        'ACE_HAS_TYPENAME_KEYWORD', when it is defined ACE_TYPENAME
        expands to 'typename' when not it expands to nothing.
        On the cases where HP/aCC requires the usage of 'typename' I added
        a 'ACE_TYPENAME'.

        * ace/OS.i: 
        * ace/OS.cpp: 
        ACE_OS::inet_aton cannot be inlined under HP-UX.

        * ace/Connector.h: 
        * ace/Connector.cpp: 
        I have decided to use a typedef (PEER_ADDR) instead of
        ACE_PEER_CONNECTOR_ADDR, mainly because the second form
        requires a ACE_TYPENAME before each usage.

        * ace/Event_Handler_T.i: 
        Much to my surprize ACE_TYPENAME is required when using a template
        typedef as a return value.

        * ace/Local_Name_Space_T.h: 
        HP/aCC does not like the usage of a private typedef from another
        class.

        * ace/Strategies_T.h: 
        * ace/Strategies_T.cpp: 
        ACE_Process_Strategy declared two defaults constructors:
        ACE_Process_Strategy(void) and ACE_Process_Strategy(int = 1).
        The constructor code was wrong, it called open() with parameters:
        open(thr_mgr, thr_flags, n_threads)
        none of which were defined, worse, open() receives just one
        parameter (the number of processes) just as the constructor, I
        believe that C-w programming is lurking here.

        * ace/Signal.cpp: 
        Though the header file does not declare ACE_Sig_Handlers under
        HP-UX (and the code is not defined too) some auxiliary functions
        that use ACE_Sig_Handlers were defined. I removed their
        definition.
        Some day I'll try to take a look at the code, trying to find out
        was wrong with them.

        * ace/Stream_Modules.h: 
        * ace/Stream_Modules.cpp: 
        By mistake I commented out the ACE_ALLOC_HOOK_* macros; have to
        fix it *real soon*.

        * ace/Task_T.cpp: 
        No need to include "ace/Module.h" since only the template
        declaration is used. When ACE_TEMPLATES_REQUIRE_SOURCE is defined
        you end up using ACE_Thru_Task before it gets defined.
        This is no problem unless your compiler checks template sintax
        before instantiation as the HP/aCC compiler do.

        * examples/Reactor/Misc/test_demuxing.cpp: 
        ACE_MT_SYNCH was used, but it is only defined if ACE_HAS_THREADS,
        I used ACE_SYNCH instead, which is defined as ACE_MT_SYNCH if
        ACE_HAS_THREADS and as ACE_NULL_SYNCH if not.
        Maybe the semantics are wrong, but the thing compiles.

Fri Mar 21 15:10:59 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Makefile (FILES): Moved Log_Msg to the beginning of the
          source list in the ace Makefile.  This is nice because it forces
          the compilation of OS.i and that, obviously, is where you get
          the complaints for the port.  It's nice to have it at the
          beginning so you catch the errors very early on before you've
          compiled 30 or 40 files.  Thanks to Scott Halstead
          <scott.halstead@gs.com> for this suggestion.

        * ace/Memory_Pool.cpp: Added #if !defined
          (ACE_LACKS_SYSV_SHMEM) to handle systems like Chorus that
          lack this feature.  

Thu Mar 20 18:58:50 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Svc_Handler.cpp (destroy): Added a state variable to keep
          track of when we are closing down the Svc_Handler.  This is
          necessary to prevent endless recursive calls to handle_close()
          due to the recent enhancements to ACE_Timer_{List,Heap}.  Thanks
          to Bert Craytor <Bert_Craytor@peoplesoft.com> for reporting
          this.

        * tests/Conn_Test.cpp: Added a new test that makes sure the
          Acceptor, Connector, and Svc_Handler are working correctly.

        * ace: Added some more changes for Chorus.  Thanks to Wei Chiang
          <chiang@tele.nokia.fi> for these changes.

        * ace/OS.h: Added #define for SIGSEGV for platforms that lack it
          (e.g., Chorus).

        * ace: Made a bunch of minor changes to support SunOS 4.x better.
          Thanks to Scott Halstead <scott.halstead@gs.com> for reporting
          these problems.

        * tests/Conn_Test.cpp: Added ACE_TEMPLATES_REQUIRE_SPECIALIZATION
          for the various templates used in this test.  Thanks to Thilo
          Kielmann <kielmann@informatik.uni-siegen.de> for reporting this.

        * ace/Connector.cpp (connector): Fixed some minor bugs that
          prevented the ACE_Connector from compiling.  Thanks to David
          Levine for noticing this.

        * ace/OS.h: Moved the ACE_LACKS_SIGACTION block so that it will
          work on Win32.  Thanks to Matthias Kerkhoff
          <make@cs.tu-berlin.de> for pointing this out.

Thu Mar 20 22:38:27 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Timer_Heap.cpp: added template specializations.

        * netsvcs/lib/Client_Logging_Handler.cpp,
                      Name_Handler.cpp
                      Server_Logging_Handler.cpp
                      TS_Clerk_Handler.cpp
                      TS_Server_Handler.cpp
                      Token_Handler.cpp: added template specializations.
          There are still many missing from libnetsvcs.

        * tests/Conn_Test.cpp,
                Future_Test.cpp
                IOStream_Test.cpp
                Map_Manager_Test.cpp
                Message_Block_Test.cpp
                Message_Queue_Test.cpp
                Reader_Writer_Test.cpp
                SV_Shared_Memory_Test.cpp
                Thread_Pool_Test.cpp}: added template specializations.
          Thanks to Thilo Kielmann <kielmann@informatik.uni-siegen.de>
          for providing these.

        * ace/Log_Msg.cpp: removed commented-out template specialization.

        * include/makeinclude/platform_{chorus,hpux,hpux_gcc}.GNU:
          split out CFLAGS and CCFLAGS from CC and CXX.

        * ace/config-aix-4.[12].x.h: added back ACE_HAS_THREAD_SELF and
          and ACE_HAS_SVR4_DYNAMIC_LINKING; removed ACE_HAS_PTHREAD_T.
          Thanks to Chris Lahey <CLahey@cccis.com> for figuring these out.

Thu Mar 20 12:25:30 1997    <harrison@samba.cs.wustl.edu>

        * ace/ace.{mak,mdp}: Build->Settings->Code Generation->Processor is
          now set to "Pentium" instead of "Blend*" for Debug and Release
          builds.

        * ace/config-win32-msvc4.x.h:
        * ace/config-win32-msvc2.0.h:
        * ace/config-winnt-4.0-msvc4.x.h: Only define ACE_HAS_PENTIUM when
          _M_IX86 == 500.  Projects must specify Pentium in
          Build->Settings->Code Generation->Processor to use the RDTSC
          instruction in ACE_OS::gethrtime.

        * ace/High_Res_Timer.{cpp,i}: By default, High_Res_Timer is
          constructed with a scale_factor == 1.  This allowed me to remove
          all the checks for scale_factor == 0 in the code.

        * ace/High_Res_Timer.h (static gettimeofday): If
          global_scale_factor_ is not set, and we're on a platform that
          requires global_scale_factor_ (e.g., Win32),
          ACE_OS::gettimeofday will be used instead of ACE_OS::gethrtime.
          This allows the scale_factor of 1 to still result in correct
          values.

Wed Mar 19 15:02:09 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace: Added zillions of minor changes so that ACE will compile on
          the new aCC compiler for HPUX.  Thanks to Gonzalo A. Diethelm
          <gonzo@ing.puc.cl> and Carlos O'Ryan <coryan@mat.puc.cl> for
          help with this.

        * ace/SOCK_Dgram_Mcast.cpp (subscribe): In addition to the
          SO_REUSEADDR option, Irix has a SO_REUSEPORT option that must
          also be set to allow multiple sockets to bind to the same
          multicast address.  Thanks to Robert V. Head <rhead@vtcs20a> for
          reporting this.

        * ace: Added a slew of changes to support CHORUS.  Thanks to
          Wei Chiang <chiang@tele.nokia.fi> for these changes.

        * ace/config-sunos4.*.h: Added #define ACE_HAS_UNION_WAIT based
          on the recommendation of Kumar Neelakantan
          <kneelaka@painewebber.com>.

        * ace/Log_Msg.cpp (log_hexdump): Replaced the use of ::sprintf()
          with ACE_OS::sprintf() so that the return value would be correct
          on SunOS 4.x!

        * ace/OS: Added ACE_HAS_CHARPTR_SPRINTF and ACE_SPRINTF_ADAPTER
          to ACE_OS::sprintf() for SunOS 4.x platforms.  Thanks to Kumar
          Neelakantan <kneelaka@painewebber.com> for reporting this.

        * ace/Handle_Set.cpp (ACE_Handle_Set_Iterator): If the bound was
          reached in the following loop, we should set this->num_ =
          this->handles_.max_handle_ + 1 rather than go into the 2nd loop.
          Thanks to Michael Newton <michaeln@in.ot.com.au> for reporting
          this.

        * ace/Handle_Set.cpp (ACE_Handle_Set_Iterator):
          ACE_Handle_Set_Iterator::ACE_Handle_Set_Iterator did not work
          properly if called with a zero handleset, as there was no bounds
          check on the first loop therein.  Thanks to Michael Newton
          <michaeln@in.ot.com.au> for reporting this.

Wed Mar 19 16:06:32 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h,README: added ACE_HAS_AIX_BROKEN_SOCKET_HEADER to wrap
          #include of sys/socket.h with #undef/#define of __cplusplus.

        * ace/config-aix-4.[12].x.h: added ACE_HAS_AIX_BROKEN_SOCKET_HEADER,
          ACE_HAS_PTHREAD_T, ACE_LACKS_TCP_H, and ACE_LACKS_SETSCHED.
          Removed ACE_HAS_SVR4_DYNAMIC_LINKING and ACE_HAS_THREAD_SELF.

        Thanks to Daniel Montalibet <daniel_montalibet@stortek.com> for
        both of the above modifications.

        * platform_{dgux4_epc,irix5.3_g++,linux*,m88k,osf1_3.2,sco*,
          sunos4_g++,sunos5_centerline*,sunos5_g++,sunos5_sunc++*,
          unixware_g++,vxworks5.2_g++}.GNU: split out CFLAGS and CCFLAGS.
          Also, removed -lstdc++/-lm from g++ versions, because we now set
          CXX to g++ instead of gcc, so those libraries are picked up.

        * include/makeinclude/platform_osf1_4.0{,_g++}.GNU:
          added -lrt to support ACE_Sched_Params.  Thanks to
          Thilo Kielmann <kielmann@informatik.uni-siegen.de> for
          suggesting this.  Also, split out CFLAGS and CCFLAGS.

        * ace/OS.h: removed SVR4_DYNAMIC_LINKING protection around
          #define of RTLD_LAZY because it's used in ace/Parse_Node.cpp.
          Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de> for pointing
          this out.

        * ace/OS.i (thr_setcanceltype): added ACE_UNUSED_ARGS for STHREADS
          case.  Thanks to Chuck Gehr <gehr@sweng.stortek.com> for
          providing this fix.

Tue Mar 18 21:53:03 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/SOCK_Dgram_Bcast.cpp (mk_broadcast): Modified the
          SOCK_Dgram_Bcast class by adding a const char *host_name to the
          contructor, and open, and mk_broadcast methods.  If the user
          passes in the host_name, then only the broadcast address of an
          interface that has a matching ip address with the host will be
          added to the if_list_.  Otherwise, nothing changes.  Thanks to
          Paul <phan@CCGATE.HAC.COM> for this feature.

Tue Mar 18 13:20:59 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/ace.mdp: Reverted the change for DllMain as the entry point
          to ace.dll.  This is causing problems in multi-threaded
          applications. 

        * netsvcs/lib/Client_Logging_Handler.cpp: Added a check in fini()
          to make sure we have a valid handler.  If the connect attempt
          failed, this->handler_ will be set to 0.

        * tests/Mem_Map_Test.cpp: Added code that removes all temporary
          files created by the test.

        * tests/Time_Service_Test.cpp: Made sure we remove the backing
          store file left behind by a aborted clerk process.

        * examples/Reactor/Ntalker/ntalker.cpp: The ntalker now uses
          ACE::register_stdin_handler to register the STDIN. This function
          allows for portability.

Tue Mar 18 08:12:22 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Svc_Conf_y.cpp,Makefile: replaced "y.tab.c" string with
          "Svc_Conf_y.cpp" to ease debugging.  Thanks to Luca Priorelli
          <lucapri@mbox.vol.it> for suggesting this.

        * ace/IOStream.cpp (close): replaced call to
          ACE_SOCK_Stream::close () with one to generic STREAM::close ().
          Thanks to Kumar Neelakantan <kneelaka@painewebber.com> for
          reporting this problem.

        * ace/OS.h,README,config-*.h: removed ACE_HAS_RTLD_LAZY_V, and
          replaced with #define of RTLD_LAZY macro only if it's not
          already defined (and if ACE_HAS_SVR4_DYNAMIC_LINKING is defined).
          Thanks to Chris Lahey <CLahey@cccis.com> for providing this fix.

        * ace/OS.i (thr_setcancelstate, thr_setcanceltype, thr_cancel):
          added ACE_UNUSED_ARG calls to avoid compiler warnings.  Thanks
          to Chuck Gehr <gehr@sweng.stortek.com> for suggesting them.

        * ace/Local_Name_Space_T.h: moved #include of Local_Name_Space.h up
          because this file needs declaration of ACE_NS_String.  There
          _shouldn't_ be a circular include problem because the #includes are
          protected.  Thanks to Daniel Montalibet
          <daniel_montalibet@stortek.com> for reporting this problem and
          providing the fix.

        * ace/Local_Name_Space.h: removed #include of ace/Service_Config.h.

        * include/makeinclude/wrapper_macros.GNU: put -I. before
          -I$(WRAPPER_ROOT) instead of after.

        * tests/IOStream_test.cpp: added checks for receipt of proper values.

Tue Mar 18 01:38:14 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/ace.mdp: Add DllMain as the entry point of ace.dll.  This
          allows us to call WSAStartup when ace.dll is loaded in and
          WSACleanup when ace.dll is unloaded.  People using ace as a
          static library are still out in the cold with respect of getting
          WSACleanup called before the process exits. 
        
          I am not sure of two cases: (1) What happens when an application
          crashes and was not able to call WSACleanup and (2) if the
          application wants to continue using sockets when ace.dll is
          unloaded.  I hope this solves more problems than it creates ;-)

Tue Mar 18 01:38:14 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/Parse_Node.cpp: Added END_OF_LINE characters to some
          ACE_ERRORs.

        * netsvcs/{lib,servers}: Fixed the project files to produce and
          use the dll in the correct place (which is netsvcs/lib).

        * ace/Log_Record.cpp: Corrected format string for fprintf().

        * examples/Threads/test.mdp: Added context_switch_time.cpp to the
          project.

          All of the above bugs were reported by Luca Priorelli
          <lucapri@mbox.vol.it>.  Thanks for the contribution.

Mon Mar 17 12:59:56 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.{h,i}: added nanosleep (), currently supported only
          on POSIX platforms (if ACE_HAS_CLOCK_GETTIME is defined).

        * examples/Mem_Map/IO-tests/{IO_Test.cpp,test_io.cpp):
          LM_ERROR instead of ACE_ERROR, and fixed call to ACE::basename ().

        * ace/OS.cpp (sched_params): return -1 if not supported,
          instead of ENOTSUP.

        * ace/OS.cpp (fork): added ACE_UNUSED_ARG (program_name) for WIN32
          and VxWorks.

        * ace/Sched_Params.cpp (priority_min, priority_max, next_priority,
          previous_priority): not supported on MVS, via ACE_LACKS_SETSCHED.
          Thanks to Chuck Gehr <gehr@sweng.stortek.com> for figuring this
          out and providing the fix.

        * tests/Timer_Queue_Test.cpp (test_performance): changed type of
          local variable "i" to (signed) int to avoid signed/unsigned
          comparison, and eventual seg fault because a loop would never
          terminate.

Sun Mar 16 11:31:46 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Timer_{List,Queue,Heap}.h: Defined copy constructors and
          assignment operators in the private part of the class so that
          users won't accidentally make mistakes.

Sat Mar 15 21:44:45 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Timer_{Queue,List}.cpp (cancel): handle_close() should be
          called only once (especially when handle_close() implements
          "delete this;" ).  Since it is possible that the EH will be
          registered more than once, I changed the code to do the
          following:

          if (number_of_cancellations == 1)
            // Call the close hook.
            curr->handler_->handle_close (ACE_INVALID_HANDLE, 
                                          ACE_Event_Handler::TIMER_MASK);

          Thanks to Hamutal Yanay <Hamutal_Yanay@mail.icomverse.com> for
          suggesting this.

        * examples/Mem_Map/IO-tests/test_io.cpp (run_tests): Removed all
          uses of ::perror and replaced them with calls to ACE_ERROR
          macros.

        * ace/Mem_Map.i (unmap): The ACE_Mem_Map::close method does not
          work properly if the value of file_mapping_ is equal to
          ACE_INVALID_HANDLE.  In this case the method calls a useless
          close (-1).  Therefore, I changed:

          if (this->file_mapping_ != this->handle_)
            ACE_OS::close (this->file_mapping_);
 
          in:
 
          if (this->file_mapping_ != this->handle_ &&
              this->file_mapping_ != ACE_INVALID_HANDLE)
            ACE_OS::close (this->file_mapping_);

          Thanks to Sandro Doro <alex@aureus.sublink.org> for reporting
          this.

Thu Mar 13 18:21:15 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/ReactorEx.h: Change protection of methods/variables of
          ReactorEx from private to protected. Thanks to Matthias Kerkhoff
          <make@cs.tu-berlin.de> for suggesting this.

Thu Mar 13 16:31:54 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.i (thr_getprio): Added missing ACE_NOTSUP_RETURN
          for the case of pthreads && !defined (ACE_LACKS_SETSCHED).
          Thanks to Chuck Gehr <gehr@sweng.stortek.com> for
          reporting this.

Thu Mar 13 00:12:15 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/Local_Name_Space_T.cpp (dump): Added ACE_UNUSED_ARG around
          fake_this to stop the compiler from complaining about unused
          variables.

        * ace/Message_Block.cpp (ACE_Data_Block::size): Moved the copying
          of the old base before freeing it up. Thanks to Dieter Quehl
          (dietrich.quehl@med.siemens.de) for pointing this out.

        * ace/Local_Name_Space_T.cpp: Added code to the list methods such
          that structured exceptions are handled correctly.  Thanks to
          Karlheinz Dorn (karlheinz.dorn@med.siemens.de) for reporting
          this.

Wed Mar 12 21:31:51 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * examples/Reactor/Ntalker/ntalker.cpp: Made changes to the
          program which allows it to run under Win32. 

        * ace/SOCK_Dgram_Mcast.cpp: Made changes to the setting of the
          interface address so that it works correctly under Win32. 
          Thanks to Todd L. Montgomery (tmont@cs.wvu.edu), Anton van
          Straaten (anton@appsolutions.com), Ole O. Johnsen
          (Ole.Johnsen@gpi.telemax.no), Mike Flinn
          (mike.flinn@smtpgate.aws.waii.com), Steve Weismuller
          (spweismu@rsoc.rockwell.com) and others who helped out.

Wed Mar 12 17:05:52 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/config-linux-lxpthreads.h: Added ACE_HAS_IP_MULTICAST.

Wed Mar 12 16:07:07 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.i (gethrtime): Added support for VxWorks and
          other platforms that support ACE_HAS_CLOCK_GETTIME.

Tue Mar 11 21:38:42 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/OS.i (open): Improved support for passing flags through to
          CreateFile ().

Tue Mar 11 14:30:12 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-vxworks-ghs-1.8.h: added ACE_LACKS_SYS_NERR.
          Thanks to Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com> for
          reporting this.

        * ace/OS.{i,cpp} (uname, hostname): added VxWorks support.
          Thanks to Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com> for
          providing this.  (Also, uninlined ACE_OS::uname on WIN32
          and VxWorks because it contains string literals.)

        * ace/High_Res_Timer.{i,cpp}: fixed interpretation of units:
          ACE_hrtime_t is in nanoseconds, so it should be divided by
          1000000000 to get seconds.  Fixed divs/mods to first divide
          by 1000, then div/mod.  Thanks to Luca Priorelli
          <lucapri@mbox.vol.it> for identifying this problem.

          Also, removed some casts that are no longer necessary, and
          added some casts of ACE_hrtime_t values to longs to avoid
          compiler warnings.  Thanks to Matthias Kerkhoff
          <make@cs.tu-berlin.de> for pointing this out.

        * ace/Reactor.cpp (unbind): cast "index" to int to avoid
          signed/unsigned comparison.  Thanks to Matthias Kerkhoff
          <make@cs.tu-berlin.de> for pointing this out.

        * ace/ReactorEx.cpp (bind): changed type of "current_size" to
          size_t to avoid signed/unsigned comparison.  Thanks to Matthias
          Kerkhoff <make@cs.tu-berlin.de> for pointing this out.

        * ace/Timer_Heap.cpp (ctor, grow_heap): cast unsigned value
          (i + 1) to int before negating to avoid compiler warning.
          Thanks to Matthias Kerkhoff <make@cs.tu-berlin.de> for pointing
          this out.

        * examples/Threads/context_switch_time.cpp (main): added
          ACE_SCOPE_PROCESS param to ACE_Sched_Params instances so
          that the test works on WIN32.  Thanks to Luca Priorelli
          <lucapri@mbox.vol.it> for identifying this problem.

        * ace/Registry.{h,cpp},Registry_Name_Space.{h,cpp},Svc_Conf_Tokens.h,
          Svc_Conf_{l,y}.cpp,Timer_{Heap,List}.cpp,config-aix-4.2.x.h,
          config-dgux-4.11-epc.h,config-mvs.h,config-sco-5.0.0-fsu-pthread.h,
          config-sco-5.0.0-mit-pthread.h,config-sco-5.0.0-nothread.h:
          added CVS header (Id wrapped in $).

        * netsvcs/clients/Logger/indirect_logging.cpp (main): declare loop
          index as signed int to avoid signed/unsigned comparison.

Tue Mar 11 07:34:04 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * tests/Timer_Queue_Test.cpp: Added some code to illustrate how
          the new handle_close() hook for ACE_Timer_{Heap,List} work.

        * ace/Timer_Heap.cpp (cancel): Modified the Timer_Heap and
          Timer_Queue so that it will call the handle_close() hook when
          Event_Handler's are cancelled.  This is necessary to reclaim
          resources.  Thanks to Hamutal Yanay
          <Hamutal_Yanay@mail.icomverse.com> for suggesting this.

        * ace/Event_Handler.h (signal): Added a TIMER_MASK, which is
          passed to handle_close() when a timer is cancelled.

        * ace/Log_Msg.cpp (log): Fixed a bug by setting LPTSTR lpMsgBuf =
          0 on line 524.  Thanks to Mark Wright <markw@odi.com.au> for
          reporting this.

Sun Mar  10 13:06:04 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * examples/Mem_Map/IO-tests: Fixed a small bug in "IO_Test.cpp"
          file.  In the "int Mmap1_Test::run_test" method I inserted an
          lseek to rewind the output file.  With this correction the speed
          go up due to IO cache.  Thanks to Sandro Doro
          <alex@aureus.sublink.org> for reporting this.

Sun Mar  9 18:24:37 1997  Prashant Jain  <pjain@merengue.cs.wustl.edu>

        * java/src/IOCntlMsg.java (IOCntlMsg): Added two new
          classes/files, namely IOCntlCmds and IOCntlMsg.

        * java/src/Task.java: Added accessors to get/set the flags of the
          Task. 

Sun Mar  9 13:06:04 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Reactor: Fixed an evil bug where the expression
        
          if (handle >= 0 || handle < this->max_handlep1_)
          
          should be
          
          if (handle >= 0 && handle < this->max_handlep1_)

          Thanks to Mark Wright <markw@odi.com.au> for reporting this.

Sun Mar  9 13:06:04 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * apps/Gateway: Updated the Peer and Gateway applications so that
          they don't try to register ACE_STDIN with the Reactor on Win32.

        * apps/Gateway: Changed a bunch of calls to
          ACE_Reactor::remove_handler() so that it no longer tries to
          remove descriptor 0, but instead uses ACE_STDIN.  Naturally,
          this doesn't work due to the way that Win32 implements select()
          but at least it compiles...  Thanks to Elliot Lau
          <eeklau@post1.com> for reporting this.

        * apps/Gateway/Gateway/File_Parser: Changed the enumerated type
          ERROR to PARSE_ERROR to avoid a name clash with a symbol
          reserved by Win32 (barf).  Thanks to Elliot Lau
          <eeklau@post1.com> for reporting this.

Sat Mar  8 12:37:44 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Log_Msg.cpp: Changed the implementation of ACE_Log_Msg so
          that all accesses to the lock_ are now through a Singleton.
          This makes it possible to define multiple instances of
          ACE_Log_Msg within the same thread.  Thanks to Jeff Morgan
          <jeff@audioactive.com> for helping track this down.

        * Added support for SCO 5.0.  Thanks to Auturo
          <mitosys@colomsat.net.co> for these patches.

Thu Mar 06 13:24:04 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.i (gettimeofday): moved declaration of "result" so
          that it's not declared on VxWorks, where it's not needed;
          (stat): added cast of file arg to char * for VxWorks;
          (thr_getprio): added missing "#else" before ACE_NOTSUP_RETURN (-1).
          Thanks to Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com> for
          reporting these.

        * ace/OS.cpp (sched_param): with STHREADS, map ACE_SCOPE_THREAD
          to ACE_SCOPE_PROCESS'.

        * ace/Svc_Conf_l.cpp: commented out YY_BREAK after ace_yyterminate ()
          to avoid GHS compiler warning about unreachable statement.
          Thanks to Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com> for
          reporting this.

        * ace/ace.mak: removed Thread_Priority and renamed Scheduling_Params
          to Sched_Param.

        * examples/IPC_SAP/SOCK_SAP/FD-unserver.cpp (handle_client):
          added "l" qualifier for sprintf of ACE_OS::getpid ().

        * tests/Priority_Task_Test.cpp,
          examples/Threads/{context_switch_time.cpp,Makefile}:
          adapted to new thread priority/ACE_Sched_Params.

Wed Mar  5 14:33:04 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/UNIX_Addr.cpp: Enhanced the implementation of set() so
          that it works correctly on MVS, which has a different definition
          of struct sockaddr_un:
          
          struct sockaddr_un {                                               
                unsigned char  sun_len;                                         
                unsigned char  sun_family;                                      
                char  sun_path[108];                                   
          };

          Thanks to Chuck Gehr <gehr@sweng.stortek.com> for reporting
          this.

Wed Mar 05 14:47:14 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.{h,cpp},Makefile; also, renamed Scheduling_Params.* to
          Sched_Params.* and removed Thread_Priority.*:

          Major change in scheduling parameters interface:
          The key change is that there is no longer a special thread priority
          enum.  Thread_Priority was changed to int, so applications can do
          whatever they want.  The ACE_Sched_Params class has some static
          functions to help do this portably.

          Here  are the changes from the ACE 4.1.3:

          1) ACE_Thread_Priority:  removed this class.

            It contained "priority class" and "thread priority".
            "Priority class" is platform-specific and doesn't
            need to be visible in ACE; it is subsumed by scheduling policy,
            see below.  "Thread priority" is replaced by the global
            ACE_Sched_Priority typedef in ace/OS.h, see next change.

          2) ace/OS.h:  added ACE_Sched_Priority typedef (to int)
             and ACE_SCOPE_THREAD.

          3) ace/OS.h:  added scheduling policy #defines:  ACE_SCHED_OTHER,
             ACE_SCHED_FIFO, and ACE_SCHED_RR.  There's an ACE_Sched_Params::
             Policy typedef that can take one of these values.

          4) ACE_Sched_Params:  added priority_min (), priority_max (),
             next_priority (), and previous_priority () functions.  All
             require an ACE_Sched_Params::Policy argument and take an
             optional scope argument (to support the distinct thread
             and process priorities on DEC UNIX).

             min_priority () and max_priority () have platform-specific
             and policy-specific values, and direction (the min value may
             be higher than the max value).  The increment and decrement
             operations allow applications to iterate over them, etc.,
             without explicitly specifying the direction of the priority
             (0 for high or low priority).

          5) The only way to apply ACE_Sched_Params is through
             ACE_OS::sched_params (const ACE_Sched_Params &).
             (This is not really a change, except for the name change from
             ACE_OS::set_sched_params ().

             It sets both policy and priority of current thread or
             process (depending on the scope in ACE_Sched_Params).
             Not all combinations of policy, priority, and scope are
             legal on all platforms.  Unfortunately, I see no way around
             this, because the intersection of legal ranges
             on our supported platforms is empty.  If an illegal request
             is made, ACE_OS::sched_params () sets errno to EINVAL and
             returns -1.

          6) added ACE_OS::thr_setprio (const ACE_Sched_Priority prio)
             to set the current thread's priority, only.

          Many thanks to Thilo Kielmann <kielmann@informatik.uni-siegen.de>
          for his careful review of this class design, thoughtful comments,
          and assistance with implementation, especially for PTHREADS
          platforms.

Wed Mar  5 14:36:59 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * SString.cpp: Fixed ACE*String initialization bugs. Thanks to
          jmorey@tbi.com (John Morey) for reporting this.

Wed Mar  5 14:33:04 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.i: Fixed a bug in gethrtime

          const ACE_Time_Value now = ACE_OS::gettimeofday (void);

          which should be

          const ACE_Time_Value now = ACE_OS::gettimeofday ();

          Thanks to Chuck Gehr <gehr@sweng.stortek.com> for reporting
          this.

Tue Mar  4 16:37:26 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * examples/IPC_SAP/SOCK_SAP/CPP-unserver.cpp (main): Make life
          easier by doing an unlink(rendezvous) before reopening the
          UNIX-domain socket.  Thanks to Jeff Morgan
          <jeff@audioactive.com> for suggesting this.

Sun Mar 02 19:58:00 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config*.h: removed #define of ACE_HAS_INLINED_OSCALLS
          because it's no longer needed in the config files:  it's
          #defined in OS.h if needed.

Sun Mar  2 17:14:29 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * include/makeinclude: Updated all the platform-*g++.GNU files so
          that they no longer -D__ACE_INLINE__ (since this is handled in
          the the config-*g++.h files).

        * ace: Updated all the config-*g++.h files so that they now
          #define __ACE_INLINE__ rather than having this set in the
          platform_*.GNU file.  This makes ACE easier to build and
          integrate with other software packages.

Fri Feb 28 02:22:33 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/SOCK_*: There were problems starting UDP broadcast servers
          (all using the same well known port number) multiple times on
          one machine (this is very useful test distributed applications
          on one single machine).  Setting the SO_REUSEADDR option for the
          broadcast socket allows binding of a socket that is already in
          use and thus allows us to start more than one broadcast servers
          in parallel on one machine.  Thanks to Dieter Quehl
          <dietrich.quehl@med.siemens.de> for this fix.

          Therefore, I patched ACE_SOCK_Dgram_Bcast, ACE_SOCK_Dgram and
          ACE_SOCK to include this feature.  In addition, I also changed
          ACE_SOCK_Connector/ACE_SOCK_Acceptor to use this feature instead
          of calling setsockopt() there explicitly.

        * examples/IPC_SAP/SOCK_SAP/FD-unserver.cpp (main): Fixed up the
          use of ACE_OS::fork() here to use the new "named" version.

        * ace/OS.h: Added a clever new wrapper function called fork (const
          char *program_name), which calls fork() and then automatically
          calls ACE_LOG_MSG->sync (program_name) to sync up the program
          name.  This eliminates a common source of error when forking
          children and using ACE_Log_Msg::log().

        * examples/IPC_SAP/SOCK_SAP/FD-un{client,server}.cpp: Updated the
          FD client and FD server programs so that it is now a concurrent
          server.

        * ace/config-mvs.h: Added #define ACE_LACKS_TCP_H for MVS.  Thanks
          to Chuck Gehr for pointing this out.

        * ace/OS.h: Added a new #define ACE_LACKS_TCP_H that skips the
          inclusion of the netinet/tcp.h file if it isn't on the platform.

        * ace/OS.i (thr_cancel): Changed the line

          ACE_UNUSED_ARG (t_id);

          to

          ACE_UNUSED_ARG (thr_id);

          Thanks to Chuck Gehr <gehr@sweng.stortek.com> for reporting
          this.

        * ace/SString.cpp: Fixed up all the ACE_[CSW]String code so that
          always allocates a rep_ even in the null constructor.  This
          saves us from having to handle odd special cases later on...
          Thanks to John Morey <JMOREY@tbi.com> for reporting this.

        * ace/Service_Repository.cpp (close): Changed the order in which
          services are destroyed when the Service Configurator is closed.
          Currently, services are destroyed in the order in which they are
          created according to the svc.conf file.  Now, we shut them down
          in reverse order.  This makes more sense when services are
          related, i.e., one service has to be started before another.
          Thanks to Karlheinz for this suggestion.


Fri Feb 28 12:13:09 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: fixed definition of ACE_TIMER_SKEW.  Thanks
          to Chuck Gehr <gehr@sweng.stortek.com> for pointing this out.

Thu Feb 27 21:36:28 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.{i,cpp} (gethrtime):  support on all platforms by
          using ACE_OS::gettimeofday () if there is no native high
          resolution timer. Moved ACE_OS::getimeofday () definition
          toward top of OS.i so that it is always defined before
          being called.  Finally, expanded gethrtime () support from
          linux to __GNUC__ with ACE_HAS_PENTIUM; it should work on
          platforms such as VxWorks with gcc on Pentiums.

        * ace/config-osf1-4.0-{,g++}.h:  added ACE_HAS_CLOCK_GETTIME.
          Thanks to Thilo Kielmann <kielmann@informatik.uni-siegen.de>
          for pointing this out.

Thu Feb 27 17:06:12 1997    <harrison@samba.cs.wustl.edu>

        * ace/High_Res_Timer.h (get_env_global_scale_factor):  This static
          method will set the global_scale_factor to the value in an
          environment variable (ACE_SCALE_FACTOR by default).

        * ace/High_Res_Timer.*: Changed all calculations to divide by
          scale_factor before doing / and %.  This must be done before the
          mod for correctness.

        * ace/Profile_Timer.i (start): Changed start and stop methods to
          call ACE_High_Res_Timer::gettimeofday.  This should allow
          greater timing accurracy.

        * ace/High_Res_Timer.h (global_scale_factor): Added a static
          global_scale_factor that allows applications to set one scale
          factor for all high res timers.  This is important for platforms
          like intel where the scale factor will vary based on the
          processor clock speed.

        * ace/High_Res_Timer.i (gettimeofday): This static method calls
          ACE_OS::gethrtime and converts to an ACE_Time_Value based on the
          global_static_factor.

Wed Feb 26 18:28:35 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ACE-install.sh: Added some fixes for the ACE-install.sh script.
          Thanks to Eugene R. Somdahl <gene@endo.com> for reporting these.

        * ace/Connector.cpp (handle_close): Added a test to see if the
          reactor_ is NULL and if it is, don't bother trying to use it to
          clean up.  Thanks to Paul Han <phan@CCGATE.HAC.COM> for this
          suggestion.

Tue Feb 25 21:19:57 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h,config-sunos*.h: default ACE_TIMER_SKEW to 0,
          and override to 10 ms in all Solaris config files.

        * ace/Svc_Conf_l.cpp,Makefile: #undef ACE_HAS_TERM_IOCTLS
          so that /usr/include/sys/termios.h won't be included; it
          #defines ECHO, and Svc_Conf_l.cpp has an ECHO symbol.

        * ace/ACE.cpp (sock_error): added ACE_UNUSED_ARG (error);.

        * ace/Timer_Queue.cpp (ctor): rearranged initializers to
          match declaration order.

Tue Feb 25 19:57:54 1997    <harrison@samba.cs.wustl.edu>

        * ace/Timer_Queue.cpp (gettimeofday): Added gettimeofday accessors
          on the Timer_Queue.  The default implementation calls
          ACE_OS::gettimeofday.  Applications can specify, via pointers to
          functions, that a timer queue use an alternate gettimeofday
          implementation (e.g., a high resolution timer).

        * ace/Reactor.cpp (schedule_timer): The Reactor no longer calls
          ACE_OS::gettimeofday.  Instead, it calls
          Timer_Queue::gettimeofday.

        * ace/ReactorEx.cpp (schedule_timer): The ReactorEx no longer calls
          ACE_OS::gettimeofday.  Instead, it calls
          Timer_Queue::gettimeofday.

Tue Feb 25 17:40:57 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Log_Msg.cpp: Updated the 'p' option of the log() method to
          use the new ACE::sock_error() method for cases where
          FormatMessage() fails.

        * ace/ACE: Added a new sock_error() method to class ACE which
          returns the appropriate message for each WinSock error code.
          This makes up for an apparent oversight in Win32.  Thanks to
          Michael R. MacFaden" <mrm@cisco.com> for this.

Tue Feb 25 01:33:06 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.h: Moved <netinet/tcp.h> outside of the VXWORKS #ifdef
          since it seems to be available on other platforms (e.g.,
          Solaris).  If people find this not to be the case on all
          platforms please let me know and I'll #ifdef it.  Thanks to
          Sumedh Mungee <sumedh@cs.wustl.edu> for reporting this.

Tue Feb 25 16:20:29 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * examples/Connection/non_blocking/CPP-acceptor.cpp: Added a
          specific checl for timeouts. Also, changed
          ACE_PEER_ACCEPTOR_ADDR to ACE_PEER_STREAM_ADDR

        * examples/Connection/non_blocking/non-blocking.{mak,mdp}: New
          project files for Win32.

        * ace/Log_Msg.cpp: Minor changes.

Mon Feb 24 17:16:06 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Log_Msg.cpp (ACE_Log_Msg): Enable the thread-specific
          tracing flag by default.  This ensures that tracing will work
          "out of the box."

        * ace/config-sunos5.[45]-g++.h: Added a #define for
          ACE_HAS_TERM_IOCTLS.  Thanks to Joey Zhu <joey.zhu@wcom.com> for
          reporting this.

        * ace/Synch.cpp (acquire): Simplified the recursive mutex logic
          for acquire().  Thanks to Arthur J. Lewis" <hfdh99a@prodigy.com>
          for reporting this.

        * examples/Connection/non_blocking/CPP-acceptor.cpp (init): Added
          a #ifdef for ACE_WIN32 so that we don't register the signal
          handler for SIGPIPE since it's not supported on Win32.  Thanks
          to Ivan Murphy <Ivan.Murphy@med.siemens.de> for reporting this
          problem.

        * examples/Connection/non_blocking: The SPIPE examples in
          (test_spipe_{acceptor,connector}.cpp) aren't ported to Win32
          yet.  They currently don't work because ACE_SPIPE*'s can't be
          registered with the ACE_Reactor (which only works with sockets).
          I've #ifdef'd these examples so that they don't get compiled on
          Win32.  Thanks to Ivan Murphy <Ivan.Murphy@med.siemens.de> for
          reporting this problem.

Mon Feb 24 20:28:10 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: use signed __int64 for ACE_hrtime_t because VC++
          won't convert unsigned __int64 to double.  Thanks to Irfan
          <irfan@cs.wustl.edu> for reporting this.

        * include/makeinclude/platform_{irix5.3_g++,linux*,m88k,
          osf1_4.0_g++,sco-nothread,sunos*g++,unixware_g++}.GNU:
          changed C++ compiler (CXX) from gcc to g++ so that libg++
          will be linked in.  Thanks to James CE Johnson <jcej@lads.com>
          for suggesting this.

        * examples/IOStream/{client,server}/Makefile,tests/Makefile:
          removed -lg++, when gcc is the compiler, because it's no
          longer needed with g++ as the compiler.

Sat Feb 22 23:03:45 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.i: restored version 4.89 and 4.90 changes that
          were lost in version 4.91.

        * ace/OS.{i,cpp},config-linux*.h: added ACE_OS::gethrtime ()
          support for Linux on Pentiums.

        * ace/High_Res_Timer.*: changed scale_factor type from
          u_long to double so that it can be less than 1.

        * ace/Thread_Priority.cpp: "linux" instead of "LINUX".

        * tests/Priority_Task_Test.cpp (open): set this->priority_ because
          an assertion uses it.  Also, use ACE_NORMAL_PRIORITY_CLASS so that
          root doesn't have to run the test on Solaris.

Sat Feb 22 22:07:35 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * tests/Priority_Task_Test.cpp (open): Now use
          ACE_Thread_Priority while setting the priority of the new
          thread.

        * ace/Thread_Priority.cpp (convert_to_os_priority): Changed
          return type for this to 'int' from 'long' on Linux.  Thanks
          to James CE Johnson <jjohnson@lads.com> for pointing this
          out!

        * ace/OS.i (thr_cancel): Corrected erroneous macro argument.
          Thanks to James CE Johnson <jjohnson@lads.com> for pointing
          this out!

Sat Feb 22 17:00:59 1997    <harrison@samba.cs.wustl.edu>

        * ace/OS.i (gethrtime): Added support for intel's RDTSC
          instruction for pentium architectures.

Sat Feb 22 10:57:47 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Stream.cpp (open): Make sure that if we allocate the Tasks
          in the Stream head and the Stream tail that we set the M_DELETE
          flag so that the close() method will clean up the memory.
          Thanks to David Levine and Purify for noticing this problem.

Fri Feb 21 08:06:41 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.i: Yikes, it looks like the Solaris and the POSIX version
          of sigwait() are different!  The Solaris version returns the
          signal number, whereas the POSIX version returns 0 on success,
          errno on failure, and sets a parameter with the signal on
          success.  I've fixed the ACE_OS C++ wrapper so that the right
          thing happens, i.e., errno is always set to the error (if
          sigwait() returns -1) and the signum is always returned as the
          argument and the return value on success ...  Thanks to Harry
          Gunnarsson <hg@carmenta.se> for reporting this.

Fri Feb 21 11:01:22 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Thread_Priority.cpp: fixed return type of
          convert_to_os_priority () for Linux.  Thanks to
          James CE Johnson <jcej@lads.com> for pointing this out.

        * examples/Shared_Malloc/test_malloc.cpp,
          examples/System_V_IPC/SV_Message_Queues/{T,}MQ_Server.cpp (main):
          added ACE_UNUSED_ARG (sa);.

Fri Feb 21 04:12:31 1997    <irfan@TWOSTEP>

        * ace/OS.h: Added ACE_SEH_FINALLY.

        * ace/ReactorEx.h: Added ACE_ReactorEx_Test as a friend class. I
          think we should have one such friend class for all classes in
          ACE.

        * examples/Reactor/ReactorEx/test_exceptions.cpp: New test which
          checks how ReactorEx deals with structured exceptions thrown by
          user code

        * ace/ReactorEx.cpp (safe_dispatch): Added protection against
          structured exceptions caused by user code when dispatching
          handles

Thu Feb 20 17:32:54 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * apps/Gateway: Added a new -v flag to the peerd and gatewayd
          applications so that they will print out the strings that are
          passed to them.  This makes it easier to debug and see what's
          happening.

Wed Feb 19 19:39:06 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * apps/Gateway/Gateway/Concrete_Proxy_Handlers.cpp (recv): Removed
          the VERBOSE #ifdefs since they weren't used and were causing
          compile errors.  Thanks to Bert Craytor
          <Bert_Craytor@peoplesoft.com> for reporting this.

Wed Feb 19 00:39:50 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * examples/ASX/Event_Server: Updated the README file a bit to
          clarify some loose ends.  The documentation now explains
          precisely how to start up the transceivers correctly.  Thanks to
          Patty Genuald <genualdp@agcs.com> for suggesting this.

        * include/makeinclude: Removed the default symlink for
          platform_macros.GNU since it is "Solaris-biased" ;-).  Thanks to
          Amos Shapira <amos@dsi.co.il> for reporting this.

Wed Feb 19 14:41:18 1997  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

        * ace/Reactor.cpp: Modified to use timer_queue_->gettimeofday().

        * ace/Proactor.cpp: Modified to use timer_queue_->gettimeofday().

        * ace/ReactorEx.cpp: Modified to use
          timer_queue_->gettimeofday().  Also had to modify the
          ReactorEx_Notify mechanism to use the ReactorEx's timer queue to
          call gettimeofday.

        * ace/Timer_Queue.h: Added a gettimeofday method.  This allows
          applications to replace the timer mechanism used by the
          Reactors.  The default implementation returns
          ACE_OS::gettimeofday.  However, a real-time application can
          inherit from Timer_Queue and override gettimeofday to return a
          value from a high resolution timer.

        * STL/bool.h: Changed the defines for type bool.  First, bool is no
          longer defined for WIN32 since yvals.h typedefs it already.
          Also, I moved the defines out the namespace.  I'm not sure if
          that's the right thing to do.

Tue Feb 18 16:41:02 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * include/makeinclude: Added minor enhancements to rules.local.GNU
          and wrapper_macros.GNU so that it works with MVS.  Thanks to
          Chuck Gehr <gehr@sweng.stortek.com> for this.

        * include/makeinclude: Added a new platform_mvs.GNU file that
          supports builds on MVS!  Thanks to Chuck Gehr
          <gehr@sweng.stortek.com> for this.

        * tests/TSS_Test.cpp (worker): To get TSS_Test.cpp to compile on
          MVS we changed line 69 from:

          ACE_thread_key_t key = 0;
 
          to:
 
          ACE_thread_key_t key = ACE_OS::NULL_key;
 
          and line 122 from:
 
          key = 0;
 
          to:
 
          key = ACE_OS::NULL_key;

          Thanks to Chuck Gehr <gehr@sweng.stortek.com> for reporting
          this.

        * ace/Reactor.cpp (dispatch): Fixed the dispatching logic so that
          we bail out as soon as we discover that our state has changed.
          Thus, we'll recompute the fd_sets used for select().

Tue Feb 18 19:02:53 1997    <irfan@cha-cha.cs.wustl.edu>

        * ace/ReactorEx: 

        (a) Made wakeup_all_threads() public. Thanks to Hamutal Yanay
            <Hamutal_Yanay@mail.icomverse.com> for suggesting this.

        (b) Change closed_for_business_ to open_for_business_. Also made
            sure that open and close can potentially be called multiple
            times from multiple threads.

        (c) Changed unbind and unbind_all such that they iterate through
            all the handles.

        (d) Added a check to see if the handle has been scheduled for
            deletion before dispatching it.

Tue Feb 18 21:24:57 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/IOStream.h,README: replaced ACE_WIN32 conditional with
          ACE_LACKS_IOSTREAM_FX.

        * ace/config-{mvs,win*}.h: added #define ACE_LACKS_IOSTREAM_FX.
          Thanks to Chuck Gehr <gehr@sweng.stortek.com> for pointing
          out the need for this support for MVS.

        * examples/Reactor/Misc/test_demuxing.cpp: removed unused
          variable "done".

        * examples/Reactor/Misc/test_signals_1.cpp (main),
          examples/Reactor/Ntalker/ntalker.cpp (main):
          added ACE_UNUSED_ARG (sig);.

Tue Feb 18 17:15:24 1997  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

        * ace/ace.mdp, ace/mak: Modified release configuration to build
          acer.dll.

Tue Feb 18 11:43:04 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Log_Msg.cpp: removed destructor because it's not declared
          and it's empty.

        * ace/OS.i (thr_setprio): added another case (that is NOTSUP)
          for platforms with Pthreads and with LACK_SETSCHED.  Thanks to
          Chuck Gehr <gehr@sweng.stortek.com> for pointing this out.

        * tests/Reactor_Notify_Test.cpp (main): added shutdown flag so
          that normal termination reaches ACE_END_TEST.

        * tests/Reactors_Test.cpp (worker): changed "timeout" message to
          "Reactor shutdown" because that indicates normal termination,
           and won't fool the one-button test.

        * examples/Mem_Map/IO-tests/test_io.cpp (main): added
          ACE_UNUSED_ARG (sa);.

        * examples/Misc/test_trace.cpp (main): added ACE_UNUSED_ARG
          for sig1 and sig2.

Tue Feb 18 03:50:10 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/ReactorEx: 

          (a) Added a closed_for_business_ flag so that handle_events()
              cannot be called after the ReactorEx has been closed down.

          (b) Transfer of ownership of the ReactorEx to a new owner has
              changed. The transfer will not complete until all threads
              are ready for it (just like the handle set).
              ReactorEx->update_state() now looks out for changes in
              ownership.

        * examples/Reactor/ReactorEx/test_MT.cpp:
          
          (a) The test now terminates and number of iterations can be
              specified on the command line.
              
          (b) Graceful shutdown of ReactorEx is now exercised in the
              test. This is a change for the earlier infinite loop. This
              also shows how to gracefully close ReactorEx which is being
              shared by multiple threads.

          (c) Timers were added to the test.

        * ace/config{win32}: Added flag ACE_LACKS_LINEBUFFERED_STREAMBUF.

Mon Feb 17 22:37:35 1997  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

        * ace/Log_Msg.h (ACE_RETURN): Modified all ACE_RETURN macros to
          use ACE_OS::last_error instead of errno.  This makes these more
          portable to Win32.

        * ace/Log_Msg.cpp (log): Modified Win32 version to use
          FormatMessage if errnum is greater than sys_nerr.

        * ace/OS.i (last_error): Modified Win32 version to return
          GetLastError if errno == 0.

Mon Feb 17 18:32:29 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/OS.h: Protected the #ifdef for CLOCK_REALTIME so that it
          won't conflict with an existing macro in AIX.  Thanks to Chris
          Lahey <CLahey@cccis.com> for this.

        * ace/Local_Name_Space_T.h: Added Local_Name_Space.h to
          Local_Name_Space_T.h so that templates will work correctly on
          AIX.  Thanks to Chris Lahey <CLahey@cccis.com> for this.

        * tests: Added a new test, Reactor_Notify_Test.cpp, which tests
          out the new max_notify_iterations() method on the Reactor.

        * ace/Reactor: Finished rewriting and testing the new dispatching
          logic of the Reactor.  The new implementation guards against
          pathological cases where ACE_Event_Handler::handle_*() methods
          remove registered ACE_Event_Handler objects whose handles are
          pending in the dispatch_set.  Previously there was no good way
          to guard against this.  Now, it should be handled automatically.

        * ace: Added many minor fixes to remove warnings with the SGI C++
          compiler.  Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for
          suggesting this.

        * include/makeinclude/platform_irix6.2_sgic++.GNU: Turned on all
          the warnings for the SGI C++ compiler.  Thanks to Gonzalo
          Diethelm <gonzo@ing.puc.cl> for suggesting this.

Mon Feb 17 20:59:47 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/IOStream.h: added null ipfx (), etc., methods for ACE_WIN32
          because its iostream class doesn't have them.

        * ace/OS.h: added #include of <netinet/tcp.h> on VxWorks.

        * ace/Pipe.cpp (open): enabled TCP_NODELAY on VxWorks now that
          OS.h #includes <netinet/tcp.h>.

        * ace/ReactorEx.h: made ACE_ReactorEx_Handler_Repository destructor
          virtual because the class has other virtual functions.

        * tests/IOStream_Test.cpp: removed ACE_WIN32 #ifndef, and
          removed q_char bool conversion operator because it shouldn't
          be needed.

        * examples/Reactor/Misc/pingpong.cpp (handle_input): cast buf_len
          to ssize_t to avoid signed/unsigned comparison.

        * examples/Service_Configurator/IPC-tests/client/\
          remote_dgram_client_test.cpp (main): cast mmap.size () to
          ssize_t to avoid signed/unsigned comparison.

Mon Feb 17 09:25:08 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/config-linux-lxpthreads.h: Bumped the Linux kernel version
        number assigned to the symbol LINUX.  Also added conditional
        defines for PTHREAD_{MAX,MIN}_PRIORITY when using Xavier Leroy's
        LinuxThreads.

        * ace/Thread_Priority.cpp: Added convert_to_os_priority() for Linux.
        
Mon Feb 17 03:15:48 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * tests/SOCK_Test.cpp (server): Changed recv_n() to recv().

        * tests/tests.{mak,mdp}: Added two new tests: IOStream and
          Reactor_Notify.

        * ace/Reactor: Removed all special checks for setting
          ACE_Reactor::max_notify_iterations_ on WIN32 to be 1.  This was
          made possible after we figured out that the errno was being
          reset after the recv() call in handle_input().  This allows
          ACE_Reactor_Notify::handle_input() to serve upto
          ACE_Reactor::max_notify_iterations_ notifications in one shot
          rather than just 1 on WIN32. This should speed up the Reactor on
          WIN32 platforms.
        
Sun Feb 16 12:23:23 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Reactor.cpp: Totally rewrote the ACE_Reactor's dispatching
          mechanism so that it now keeps track of whether the state of the
          wait_set_ has changed during a dispatch (i.e., whenever
          register_handler_i() or remove_handler_i() is called).  If the
          wait_set_ state *has* changed, then we bail out and rerun
          select() in order to get the latest changes.

        * ace/Reactor.cpp: Changed the implementation of the
          ACE_Reactor_Notify class so that (1) it short-circuits a trip
          through the ACE_Reactor::notify_handle() method (after all, it's
          just going to call its own handle_input() method back) and (2)
          the ACE_Reactor_Notify::handle_input() method now returns a
          count of the number of handlers that it dispatched.

        * ace/Log_Msg.h: Added a (%P|%t) so that we now print out the
          process id and thread number for failed ACE_ASSERT() calls.

        * tests: Removed the unnecessary template specializations of
          ACE_Atomic_Op<ACE_Thread_Mutex, int> since this is already done
          in libACE.

        * ace/Reactor.cpp: Removed the #ifdef preventing the enabling of
          non-blocking mode for the recv() side of the Reactor's
          notification pipe (socket) for Win32.  I believe that with the
          new max_notify_iterations scheme we should be all set.

        * ace/ReactorEx.cpp: Added an identical API for bounding the
          max_notify_iterations() for ReactorEx.

        * ace/Reactor.cpp: Enhanced the Reactor's notify() mechanism so
          that it is now possible to set the max_notify_iterations(),
          which limits the number of times that the
          ACE_Reactor_Notify::handle_input() method will iterate and
          dispatch the ACE_Event_Handlers that are passed in via the
          notify pipe before breaking out of its recv() loop.  This is
          necessary to keep from starving out other Event_Handlers.
          Thanks to Rod Skinner <rods@in.ot.com.au> for pointing out the
          need for this.

        * ace/Reactor.cpp: Fixed a bug in the WIN32
          ACE_Reactor_Notify::handle_input() logic.  We were calling
          requeue_position(0) when we should have been calling renew().

Sat Feb 15 11:46:39 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/ACE.cpp: It appears that VxWorks doesn't support fcntl().
          However, it does seem to support ioctl().  Therefore, that's how
          we'll set the descriptors into non-blocking mode.  Thanks to
          Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com> for reporting this.

        * ace/SOCK_Stream.h: Corrected the documentation for
          ACE_SOCK_Stream::recv_n (void *buf, size_t len, int flags, const
          ACE_Time_Value *timeout).  Thanks to Paul Roman
          <proman@npac.syr.edu> for reporting this.

        * ace/SOCK_Stream.i (recv_n): Fixed a minor bug in the
          SOCK_Stream.i line 38: 

          ACE_TRACE ("ACE_SOCK_Stream::send_n");

          should be

          ACE_TRACE ("ACE_SOCK_Stream::recv_n");

          Thanks to Paul Roman <proman@npac.syr.edu> for reporting this.

Fri Feb 14 00:40:14 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/TTY_IO.cpp (control): Moved the drop out timer value from
          the ACE struct to the WinNT struct.  Thanks to Brad Flood
          <BFLOOD@tcs.lmco.com> for this fix.

Thu Feb 13 21:24:17 1997    <irfan@cha-cha.cs.wustl.edu>

        * ace/OS.i (event_wait): Fixed the missing check for success.

        * ace/Synch: Fixed problems with multiple removal of
          resources. Thanks to Bert (Bcraytor@aol.com) for pointing this
          out.

        * examples/Threads/test.{mdp,mak}: Reorganized project so that it
          is easier to use. 

        * examples/Threads: Small changes to make tests run faster.     

Thu Feb 13 01:49:38 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/OS.i (stat): Added stat() to ACE_OS.

        * apps/jaws: The ACE web server has now been ported to Win32. 

        * ace/ReactorEx: Add a new version of remove_handler().

        * examples/Reactor/ReactorEx/test_MT.cpp: Fixed stuff so that only
          <concurrent_threads> are activated.

Wed Feb 12 22:58:15 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/ReactorEx: Made minor changes to the ReactorEx.

        * examples/Reactor/ReactorEx/test_MT.cpp: Updated Irfan's new
          ReactorEx test to use ACE_Tasks.

        * ace/ReactorEx: Finished a complete rewrite of
          ReactorEx.  The new version allows multiple threads of
          control to wait simultaneously in
          ::WaitForMultipleObjects(). This was difficult because the 
          set of ACE_HANDLEs used in ReactorEx->handle_events() is 
          shared between all threads.  We devised a clever protocol
          that ensures all changes to the handle set are
          serialized. This serialization was achieved by using
          multiple (auto and manual) events and mutexes and by taking
          advantage of the "waitAll" semantics of
          WaitForMultipleObjects().

          Concept of "owner" thread is introduced in ReactorEx.  We
          need to keep track of the "owner" because we don't want
          multiple threads to try to expire timers. Therefore the
          "owner" thread is the only one allowed to expire
          timers. Also, the owner thread is the only thread which
          waits on the internal notify handle (which is used to
          dispatch explicit calls to
          ACE_ReactorEx::notify(). Initially, the creator thread of
          ReactorEx becomes the "owner" thread. Ownership can later be
          transferred among threads, just as with the standard
          ACE_Reactor.

          We also updated the Handler Repository since it now
          keeps track of <handle, event_handler> tuples to be added
          and deleted from the current handle set at the appropriate
          time (i.e., when all threads are out of
          WaitForMultipleObjects() and have completed all necessary
          dispatching).  The Handler_Repository implements the update
          protocol that is used to serialize changes to its internal
          state.
        
          Two slots were added to the <size> parameter in the
          constructor and open methods of ReactorEx that will store
          handles used for internal management. Therefore, users can add
          upto MAXIMUM_WAIT_OBJECTS - 2 handles into ReactorEx.  On
          current WinNT platforms (e.g., 3.51 and 4.0)
          MAXIMUM_WAIT_OBJECTS is 64.

          Note that the interface to ReactorEx did not change in this
          process. Your existing code should work without changes.
          Moreover, we've optimized the implementation so that if only
          1 thread calls ACE_ReactorEx::handle_events() the code is
          very efficient.  Moreover, you can dynamically add or remove
          threads without having to register them with the ReactorEx.

        * examples/Reactor/ReactorEx/test_MT.cpp: This application tests
          multiple threads simultaneously calling
          ReactorEx->handle_events(). It also shows how different threads
          can update the state of ReactorEx.

Wed Feb 12 00:08:42 1997  Douglas C. Schmidt  <schmidt@polka.cs.wustl.edu>

        * ace/Synch: Added a remove() call to ~ACE_Thread_Mutex so that it
          will be removed (and resources cleaned up) automatically when an
          ACE_Thread_Mutex object goes out of scope.  Thanks to Jay
          Denkberg <jay_denkberg@mail.icomverse.com> for reporting this.

        * ace: Added a new config file (config-irix6.2-sgic++-nothreads.h)
          that works for non-Pthread versions of SGI 6.2.  Thanks to Fred
          LaBar <flabar@fallschurch.esys.com> for this.

        * ace/XtReactor: Fixed a bunch of minor bugs that crept into the
          ACE_XtReactor.  Thanks to Fred LaBar
          <flabar@fallschurch.esys.com> for reporting this.

        * ace/OS.i (thr_getprio): Fixed a typo in the #ifdefs so that we
          return ACE_NOTSUP_RETURN(-1) if threading isn't enabled.  Thanks
          to Fred LaBar <flabar@fallschurch.esys.com> for reporting this.

Tue Feb 11 11:26:03 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.{h,i},config-vxworks*.h,README: added ACE_HAS_CLOCK_GETTIME,
          and only support ACE_OS::clock_gettime if that's defined.
          It can be supported on Solaris 2.5, but -lposix4 is then required.

        * ace/Thread_Priority.*: added increment () and decrement ()
          operations.

        * include/makeinclude/platform_sunos5_sunc++_4.1.GNU:
          added -pta back to avoid link problems with template classes
          that have virtual functions that are all inline, if inlining
          is disabled.  Though we don't see the problem, other 4.1 users do.
          Thanks to mscallinan@CCGATE.HAC.COM for reporting this.

        * examples/Logger/simple-server/Logging_Handler.cpp (handle_input):
          cast "len" to ssize_t to prevent mixed signed/unsigned comparison.

        * examples/Logger/simple-server/server_loggerd.cpp (main):
          added ACE_UNUSED_ARG (sa);.

        * examples/Reactor/Misc/notification.cpp (Thread_Handler ctor):
          changed type of n_threads argument from int to size_t to avoid
          signed/unsigned comparison.

Mon Feb 10 15:27:02 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Timer_Queue: Added a virtual destructor so that subclasses
          deleted via ACE_Timer_Queue *'s will call the right destructor.
          Thanks to Stuart Powell <stuartp@in.ot.com.au> for reporting
          this.

        * ace/Timer_Heap.cpp: Added support for automatically growing
          ACE_Timer_Heaps.  This allows heaps to grow automatically as new
          ACE_Event_Handlers are added dynamically.  Thanks to Stuart
          Powell <stuartp@in.ot.com.au> for this enhancement.

        * ace/Memory_Pool: Added support that allows flags to be passed in
          to the MMAP_Memory_Pool.  This can be used to set the
          appropriate type of backing store semantics (e.g., MAP_PRIVATE
          and MAP_SHARED).  Thanks to Fred LaBar
          <flabar@fallschurch.esys.com> for providing this.

Sun Feb  9 11:56:37 1997  Douglas C. Schmidt  <schmidt@polka.cs.wustl.edu>

        * ace/Map_Manager.cpp (bind_i): A recent change to Map_Manager
          broke the Connector since errno was getting set to ENOENT rather
          than EWOULDBLOCK.  Thanks to Mark Rabotnikov
          <mark@usp.elscintcorp.co.il> for finding this.

Sun Feb 09 21:44:34 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/ACE.{h,cpp}: added static u_long is_prime ().

        * ace/{OS.cpp,Thread_Priority.cpp}: added comment about thread
          priorities only being tested for 1003.1C version of Pthreads.
          Thanks to Thilo Kielmann <kielmann@informatik.uni-siegen.de>
          for suggesting this.

        * ace/OS.{h,i}: added ACE_OS::clock_gettime ().  It allows
          applications to get high-resolution time on POSIX systems.

        * ace/Future.cpp (dump): cast ref_count_ to an int because
          g++ doesn't figure it out (it's an ACE_Atomic_Op<ACE_Thread_Mutex,
          int>, which does have an int conversion operator).

        * ace/Timer_List.cpp (constructor): added initializer for
          timer_id_ to prevent unitialized memory read report from Purify.

        * tests/IOStream_Test.cpp,Makefile: added IOStream_Test,
          complements of James CE Johnson <jcej@lads.com>.  Very cool!

        * tests/Future_Test.cpp: replaced call to ::sin ()
          with one to ACE::is_prime () to remove dependency on libm.

        * examples/IPC_SAP/UPIPE_SAP/ex1.cpp (peer1, peer2): removed
          unused variables c_addr and serv_addr: they were replaced by
          a global.

        * examples/Threads/future{1,2}.cpp: replaced call to ::sin ()
          with one to ACE::is_prime () to remove dependency on libm.

        * netsvcs/clients/Naming/Dump_Restore/createfile.cpp: removed
          #include of math.h, it wasn't needed.

Sat Feb 08 15:19:50 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/ReactorEx.h: commented out ACE_ReactorEx_Notify::message_queue_
          declaration if not ACE_WIN32 because Sun C++ chokes on it.

        * examples/IPC_SAP/{FILE,SPIPE}_SAP/client.cpp: declare "len" as
          ssize_t to avoid signed/unsigned comparison.

Fri Feb  7 01:13:05 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.i (select): Simplified Chris' fixes for the weird
          Linux select() semantics.

        * ace/OS: Added a new accessor method called waiters() in
          ACE_cond_t that returns the number of waiters on the condition
          variable.  Thanks to Karlheinz for suggesting this.

        * ace/OS: Changed all the ACE_cont_t, ACE_rwlock_t, etc. so that
          their fields are private, but made class ACE_OS a friend.
          Applications should not be mucking with these fields since they
          may change.

        * ace/OS.h: Fixed a minor typo where friend class ACE_rwlock_t
          should be friend class ACE_OS.  Thanks to Thilo Kielmann
          <kielmann@informatik.uni-siegen.de> for reporting this.

        * ace/Log_Msg.cpp: Added a destructor to ACE_Log_Msg and changed
          ACE_TSS_cleanup so that it calls delete (ACE_Log_Msg *) ptr.
          Thanks to Per Anderson <Per.Andersson@hfera.ericsson.se> for
          reporting this.

        * tests/Map_Manager_Test.cpp: Create a file Map_Manager_Test_Key.h
          and move the class Key into the include file.  Include this *.h
          file in Map_Manager_Test.cpp.  This is needed for template
          generation on AIX.  Thanks to Chris Lahey <CLahey@cccis.com> for
          pointing this out.

Fri Feb  7 17:29:40 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/OS.cpp (set_sched_params): added support for POSIX
          threads.  Thanks to Thilo Kielmann
          <kielmann@informatik.uni-siegen.de> for figuring it out and
          for providing the code.

        * tests/Naming_Test.cpp (test_find): Changed final delete[] to
          not try to delete a static buffer. :-(

        * tests/SOCK_Test.cpp (server): Added assertion test for
          modified select timeval.

Fri Feb 07 13:56:24 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/{OS.cpp,Thread_Priority.cpp}: added ACE_Thread_Priority
          support for Digital Unix.  Thanks to Thilo Kielmann
          <kielmann@informatik.uni-siegen.de> for figuring the priorities
          and priority classes out and for providing the code.

        * ace/High_Res_Timer.{h,cpp},config-linux*.h,README:
          use struct timespec instead of timespec_t, because not all
          platforms have the timespec_t typedef.  Thanks to
          Marius Kjeldahl <marius@funcom.com> for reporting this on Linux
          and Chris Lahey <CLahey@cccis.com> for reporting it on AIX.

        * ace/IOStream.h: use "ssize_t send (...)", etc., instead of exact
          function prototypes.

        * examples/IPC_SAP/TLI_SAP/db-server.cpp: declare struct member as
          const char * instead of const char [] because it's not static and
          the struct doesn't have constructors.

        * examples/Reactor/Multicast/server.cpp (Server_Events ctor):
          reordered initializers to match declaration order.

Fri Feb 07 05:08:51 1997    <irfan@cha-cha.cs.wustl.edu>

        * ace/Synch.cpp (dump): Fixed access error.

        * ace/OS.h: Fixed ACE_rwlock_t friend declaration.

        * ace/OS.i: Moved ACE_cond_t::waiters() such that it is now
          visiable to NT. Also fixed ACE_OS::cond_timed_wait by returning
          the correct return value on a TIMEOUT. Also fixed typo in
          ACE_OS::sema_wait.    

Thu Feb  6 20:25:13 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

        * ace/OS.i (select): Adapted ACE_OS::select methods for use on
          platforms (such as Linux) that allow select(2) to modify its
          struct timeval arg.  New behavior is triggered by the define
          ACE_HAS_NONCONST_SELECT_TIMEVAL.  Thanks to Jorn Jensen
          <jornj@funcom.com> for reporting this!

Thu Feb 06 09:48:43 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-sunos-sun*.h,README: added
          ACE_LACKS_LINEBUFFERED_STREAMBUF and ACE_LACKS_SIGNED_CHAR.

        * ace/IOStream.{h,cpp}: support
          ACE_LACKS_LINEBUFFERED_STREAMBUF and ACE_LACKS_SIGNED_CHAR
          so that this builds with SunC++.

        * examples/IOStream/client/iostream_client.cpp:
          reordered args and fixed argv indexes.

        * examples/IOStream/server/iostream_server.cpp:
          use ACE_DEFAULT_SERVER_PORT for default port.

        * tests/Naming_Test.cpp (randomize): changed type of "size" arg to
          size_t to avoid compiler warnings about signed/unsigned comparison.

Thu Feb 06 09:40:47 1997  Chris Cleeland <cleeland@cs.wustl.edu>

        * ace/config-linux*.h: added typedef of timespec_t.

Wed Feb  5 01:45:03 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.i: Changed the Win32 implementation of all methods that call
          WaitForMultipleObjects() so that errno is set to
          WAIT_ABANDONED if the mutex is abandoned.  This makes it
          possible for users to understand why ACE_OS methods that use
          synchronization operations fail.  Thanks to Ivan Murphy
          <Ivan.Murphy@med.siemens.de> for reporting this problem.

        * ace/IOStream.cpp (ACE_Streambuf): Moved the const initialization
          from the header file to the constructor since this is the only
          portable way to do this.  Thanks to Michael Maxie
          <maxie@acm.org> for reporting this.

        * ace/OS.i: Updated the call to thr_setprio() for pthreads so that
          it first determines the existing scheduling parameters and then
          updates the priority.  Thanks to Thilo Kielmann
          <kielmann@informatik.uni-siegen.de> for help with this.

        * ace/config-osf1-4.0*.h: Updated ACE_NEEDS_HUGE_THREAD_STACKSIZE
          to be 1 mega to minimize porting surprises.  Thanks to Thilo
          Kielmann <kielmann@informatik.uni-siegen.de> for help with this.

        * tests/Naming_Test.cpp: Cleaned up a few minor things related to
          int i = 0 vs. size_t i = 0.

        * ace/SOCK_Dgram.cpp: Added a new macro called
          ACE_HAS_SOCKADDR_MSG_NAME, which is used on platforms (e.g.,
          DG/UX) that require a cast to (struct sockaddr *) for the
          msg_name field of struct msghdr.

Wed Feb 05 10:45:41 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/IOStream.h: replaced __*manip with expanded types, because
          Sun C++ doesn't have those typedefs; and added complete prototypes
          for send, recv, send_n, and recv_n.

        * ace/IOStream.cpp: fixed "#define ACE_IOSTREAM_C" to keep g++ sane.

        * ace/Hash_Map_Manager.{h,cpp},Map_Manager.{h,cpp}: replaced
          DEFAULT_SIZE with ACE_DEFAULT_MAP_SIZE so that Naming_Test runs
          on SunC++ 4.1.

        * ace/High_Res_Timer.*: added optional scale factor.

        * examples/IOStream/{client,server}/Makefile:  addd -g++ if building
          with gcc.

        * tests/Naming_Test.cpp: moved declaration of "i" out of for loop
          because it is used after the loop.

        * examples/ASX/UPIPE_Event_server/{Consumer,Supplier}_Router.cpp
          (open): return 1 if init () succeeds.  There's a commented-out
          call to activate the objects that would (should?) return a value.

        * examples/IPC_SAP/FIFO_SAP/FIFO-client.cpp (main): declare n
          as ssize_t instead of size_t to avoid compiler warning about
          signed/unsigned comparison.

Tue Feb  4 19:06:52 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Signal.cpp: Fixed all the ACE_Sig_Handler[s] methods so that
          they now use ACE_Guard, rather than ACE_TSS_Guard, *unless* they
          are actually performing callbacks to user-code.  Not only is
          this faster, but it also avoids thread-specific storage key
          leaks on platforms like Solaris!

        * ace/OS.cpp (thr_keyfree): Added a new #ifdef for
          ACE_HAS_THR_KEYDELETE, which is defined for UNIXWARE.  This
          fixes a nasty problem with leaking thread-specific keys.  Thanks
          to Nigel Owen <Nigel@voicelink.co.nz> for reporting this.

        * ace/Message_Block.cpp: Added a #include for
          "ace/Service_Config.h".

        * ace/Malloc.i: Fixed a few warnings by removing the names of
          unused parameters.

        * ace: Added many minor changes to ACE so that it will work on
          DG/UX.  Thanks to Michael Maxie <maxie@acm.org> for all these.

        * ace/LSOCK_Stream.cpp: Applied the same fix as to LSOCK.cpp.

        * ace/LSOCK.cpp: Removed the cast of 0 to (char *) for msg_name
          since some platforms use (struct sockaddr *).  By omitting the
          cast the compiler will figure it out correctly.  Thanks to
          Michael Maxie <maxie@acm.org> for this.

        * ace/IOStream: Added a new template adapter for creating an
          iostream-like object using an ACE IPC Stream for the actual I/O.
          Thanks to James CE Johnson <jcej@lads.com> for this.

        * examples/Misc/test_iostreams.cpp: Added a test that illustrates
          how the new ACE_iostreams mechanism works.  Thanks to James CE
          Johnson <jcej@lads.com> for this.

        * ace/Message_Block: Updated the ACE_Message_Block implementation
          to use ACE_Service_Config::alloc() if the user doesn't supply a
          customize version.  This also means that we never delete the
          allocator_strategy_, so we can remove this flag and reduce the
          amount of storage by 4 bytes.  Thanks to Irfan for noticing that
          we can do this.

        * ace/platform_dgux4_epc.h: Added a new platform config file
          for DG/UX.  Thanks to Michael Maxie <maxie@acm.org> for
          this.

        * ace/config-dgux-4.11-epc.h: Added a new config file for DG/UX.
          Thanks to Michael Maxie <maxie@acm.org> for this.

Tue Feb 04 18:26:01 1997    <irfan@cha-cha.cs.wustl.edu>

        * ace/Service_Config.cpp (alloc): The implementation now creates a
          ACE_New_Allocator rather than a ACE_Allocator_Adaptor.  If
          you still want the old behavior, simply provide your own
          custom allocator singleton for ACE_Service_Config.

        * ace/OS.i (mktemp): Added the missing ACE_INLINE directive.

        * ace/OS.h: ACE_HAS_INLINED_OSCALLS is now automatically defined
          when __ACE_INLINE__ is defined.  This avoids mysterious linking
          problems that occur otherwise.

        * ace/Malloc: Added a virtual destructor to ACE_Allocator.  Also
          added a new class ACE_New_Allocator which is a sub-class of
          ACE_Allocator. This class uses the new/delete operators to
          allocate and free up memory.  Please note that the only methods
          that are supported are malloc() and free(). All other
          methods are no-ops.  If you require more functionality, please use:
          ACE_Allocator_Adapter <ACE_Malloc <ACE_LOCAL_MEMORY_POOL,
          MUTEX>> This will allow you to use the added functionality of
          bind/find/etc. while using the new/delete operators.

Mon Feb  3 15:35:24 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/config-aix-*.h: Added a (char *) cast to
          ACE_DEFAULT_BASE_ADDR.  Thanks to John Cosby
          <John.D.Cosby@cpmx.saic.com> for reporting this.

        * ace/OS.cpp: Added a new set() method that sets the Time_Value
          from a double.  Thanks to Brad Flood for this suggestion.

        * ace/OS: Changed ACE_OS::flock_t to ACE_OS::ace_flock_t to avoid
          a name clash on DG/UX.  Thanks to Michael Maxie <maxie@acm.org>
          for reporting this.

Tue Feb  4 03:02:52 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * tests/Naming_Test.cpp: Added timing and made debug print outs
          optional. Also added randomization of the test data.

        * ace/OS.h: Fixed prototype for gethrtime ()

Mon Feb 03 21:00:56 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: define ACE_SCOPE_PROCESS and ACE_SCOPE_THREAD
          even if ACE_HAS_THREADS is not defined.  Thanks to
          Michael Maxie <maxie@acm.org> for pointing this out.

        * examples/Threads/{process_mutex.cpp,process_semaphore.cpp,
          task_three.cpp,thread_manager.cpp,thread_specific.cpp} (main):
          added ACE_UNUSED_ARG (sa);.

        * examples/Threads/reader_writer.cpp: fixed declaration of
          "shared_data" to be "static volatile" instead of "volatile
          static", and removed unused variable "n".

        * examples/Threads/thread_pool.cpp: removed unused variable "result".

Sun Feb 02 21:24:02 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: changed hrtime_t to ACE_hrtime_t.

        * ace/{config-win*.h,README}: added #define ACE_HAS_PENTIUM to
          enable gethrtime () support.

        * ace/High_Res_Time.{h,i,cpp}: removed platform-specific #ifdef's,
          instead added "unsupported ()" static member function; changed
          changed signature of elapsed_time to take time reference as
          argument instead of return value; added elapsed_time
          (ACE_Time_Value &) and elapsed_time_incr (ACE_Time_Value &).

        * examples/Thread/context_switch.cpp: use ACE_High_Res_Timer
          instead of the old Timer adapter.

        * ace/config-aix-4.1.x.h: fixed typo: #defind ACE_HAS_LONGLONG_T.

        * ace/config-aix-4.2.x.h: added #define ACE_HAS_LONGLONG_T.

        * ace/Thread_Priority.{h,cpp}: moved #include of OS.h from .cpp
          to .h file.

Sun Feb 02 10:30:29 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Local_Name_Space.cpp: removed ACE_Map_Manager, ACE_Map_Iterator,
          and ACE_Map_Entry: they don't appear to be used and, without
          including their headers, this file won't compile.

        * ace/Hash_Map_Manager.cpp (Hash_Map_Manager (ACE_Allocator *)):
          reordered initializers to match declaration order.

Sat Feb  1 15:11:28 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * include/makeinclude/platform_aix4.2.GNU (LD): Removed the -qnoro
          flag since it is no longer needed.  Thanks to Rob Jordan
          <jordan@hursley.ibm.com> for reporting this.

Sat Feb  1 03:25:21 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/SString.cpp: Added two methods to the wide string
          implementation for high-performance. Even though these methods
          are somewhat ugly and not the "OO" way of doing things,
          performance was at stake here.

        * ace/Registry_Name_Space.cpp (resolve): Fixed the implementation
          by correctly figuring out the size of the value in the
          Registry. This allows us to dynamically allocated the correct
          amount of memory.

        * ace/Registry: Fixed the constant MAX_CONTEXT_NAME_SIZE to be the
          maximum path length.

        * ace/Naming_Context.cpp: Fixed various memory leaks.

        * ace/Local_Name_Space_T.h: Replaced the simple-minded Map_Manager
          with the new (improved) Hash_Map_Manager.     

        * ace/Local_Name_Space.cpp: Added new methods operator!= and hash
          required by the map.

        * ace/Hash_Map_Manager.cpp (ACE_Hash_Map_Manager): Added an extra
          constructor.

        * tests/Naming_Test.cpp: Removed memory leaks.

Fri Jan 31 19:39:48 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Hash_Map_Manager.cpp (ctor): reordered initializers
          to match declaration order.

        * tests/Time_Value_Test.cpp: cast double argument to long
          because there no longer is a constructor that takes a double.

        * ace/Hash_Map_Manager.{h,cpp}: removed #include of
          ace/Hash_Map_Manager.i because it doesn't exist.
          Protected .cpp file against multiple includes.  Moved
          #include of "ace/Malloc.h" from .h to .cpp file.

        * ace/Map_Manager.cpp (current_size, total_size): cast -1 to
          size_t to avoid warning about signed-to-unsigned conversion.

        * ace/OS.h: moved hrtime_t typedef for ACE_WIN32 so it doesn't
          get defined twice.

        * ace/OS.i (getservbyname): one last ACE_HAS_NONCONST_GETBY change:
          missed "lproto" to "proto".

        * bin/create_ace_build: added checks for existing symlinks, so
          now the script can be re-run safely at any time on a build
          tree to update it.

Fri Jan 31 02:16:30 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/config-aix-*.h: Made the default value for
          ACE_DEFAULT_BASE_ADDR 0x80000000 to work around restrictions
          with AIX.  Thanks to Rob Jordan <jordan@hursley.ibm.com> for
          this.

        * examples/Map_Manager: Added a new example of the
          Hash_Map_Manager.

        * tests/Map_Manager: Integrated the Hash_Map_Manager into the
          Map_Manager test and greatly improved the test (e.g., by adding
          timing).

        * ace: Added a new implementation of the Map_Manager called
          Hash_Map_Manager.  This, of course, uses hashing rather than
          linear search.  The result should be a much faster
          implementation for many types of applications. 

Thu Jan 30 13:55:08 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Map_Manager: Changed the return type of total_size() and
          current_size() to size_t.

        * ace/OS: Had to remove the ACE_Time_Value (double) constructor
          since it caused ambiguities with ACE_Time_Value (long).  Thanks
          to Per Andersson for figuring this out.
  
        * include/makeinclude/platform_linux_lxpthread.GNU (CXX): Added
          -D_REENTRANT to make things work correctly in MT programs.
          Thanks to Marius for this fix.

        * ace/OS.h: Added several extra constructors for ACE_Time_Value so
          that it won't cause problems with the new ACE_Time_Value
          (double) constructor.

        * ace/Log_Record.cpp (ACE_Log_Record): Added an "L" to the 0
          initial value used for time_stamp_.  Thanks to Marius for
          reporting this.

        * ace: Added the new config-aix-4.2.x.h file, which supports the
          AIX4.2 platform.  Thanks to Rob Jordan <jordan@hursley.ibm.com>
          for this.

        * include/makeinclude/platform_aix4.2.GNU: Added support for the
          new AIX4.2 platform.  Thanks to Rob Jordan
          <jordan@hursley.ibm.com> for this.
 
        * ace/OS.h: It's now possible to override ACE_DEFAULT_BASE_ADDR in
          a config.h file.  This is important for platforms that need to
          put shared memory segments at particular address ranges.  Thanks
          to Rob Jordan <jordan@hursley.ibm.com> for suggesting this.

Thu Jan 30 16:01:37 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/{config-aix-4.1.x.h,README}: added ACE_HAS_AIX_HIRES_TIMER,
          see change to gettimeofday in OS.i below; and ACE_HAS_LONGLONG_T.

        * ace/OS.i (gettimeofday, gethrtime): use read_real_time () if
          ACE_HAS_AIX_HIRES_TIMER.  Thanks to Bob Olson
          <olson@mcs.anl.gov> for this suggestion.

        * ace/OS.h: define hrtime_t as long long if ACE_HAS_AIX_HIRES_TIMER.

        * ace/OS.{i,cpp}: uninlined ACE_OS::gethostbyname (),
          and ACE_OS::inet_ntoa () on VxWorks, because they have
          static char arrays.

        * ace/OS.i (gethostbyaddr, getservbyname, gethostbyaddr,
          gethostbyname, getservbyname_r): with ACE_HAS_NONCONST_GETBY,
          instead of copying the const argument, just cast it to (char *).
          Thanks to Michael Maxie <maxie@acm.org> for pointing out the
          problem with the nonstatic char arrays with sizes determined at
          runtime.

        * ace/High_Res_Timer.*: added ACE_HAS_AIX_HIRES_TIMER support.
          Also, renamed get_time () to elapsed_microseconds ().

        * examples/Threads/{Timer.h,context_switch_time.cpp}:
          ACE_High_Res_Timer::elapsed_microseconds () instead of
          ACE_High_Res_Timer::get_time ().

        * bin/create_ace_build: added this script: it creates an ACE build
          tree in directory "build/<build name>" below the current
          directory, which must be a ACE "top level" directory (such as
          $WRAPPER_ROOT).  The build tree directory structure mirrors that
          of the ACE top level directory structure, except that instead of
          containing any plain files, it contains only symlinks to the files
          in the ACE top level structure.

Thu Jan 30 06:57:50 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Thread_Priority.cpp (convert_to_os_priority): changed
          switch (priority_class) to switch (priority_class_).
          Thanks to Chris Lahey <CLahey@cccis.com> for pointing this out.
          Also, return -1 on other than Solaris, Win32, and VxWorks.

Wed Jan 29 22:05:01 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * tests/Naming_Test.cpp: Added the prefix "test_" to the bind(),
          find(), rebind(), and unbind() functions.  This avoids name
          clashes with the bind() call from the socket API.  Thanks to
          Marius for this info.
          
        * ace/OS.cpp (ACE_Time_Value): Added a new constructor that makes
          it possible to construct an ACE_Time_Value from a double.
          Thanks to Brad Flood <BFLOOD@tcs.lmco.com> for this.

        * ace/OS.i (thr_join): If ACE_HAS_THREADS is defined, but none of
          the threading APIs match (e.g., AIX) then we'll return
          ACE_NOTSUP_RETURN(-1).  Thanks to Chris Lahey for help with
          this.

        * include/makeinclude/platform_aix.GNU: Made some changes to the
          type of dynamic linker and libraries used by AIX 4.1.  Thanks to
          Chris Lahey for help with this.

        * ace/config-aix-4.1.x.h: Changed from BSD 4.3 to 4.4.  Thanks
          to Chris Lahey for help with this.

Wed Jan 29 09:03:48 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: moved ACE_id_t and ACE_pri_t typedefs out of the
          ACE_HAS_THREADS section.

        * ace/OS.cpp: fixed ACE_OS::set_sched_params on Win32 and VxWorks.

        * ace/Scheduling_Parameters.*, ace/Thread_Priority.*: updated
          comments.

        * examples/Threads/{context_switch_time.cpp,Timer.h,Makefile}:
          added context switch timing test.  Currently only works on
          Suns because that's the only platform for which ACE has a
          high-resolution timer.

        * Makefile: added chmod of VERSION file in TIMESTAMP macro.

Wed Jan 29 00:59:12 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * include/makeinclude/platform_linux_lxpthread.GNU (CXX): Removed
          the -D_MIT_POSIX_PTHREADS symbol since we're using Xavier's
          threads instead.  Thanks to Marius Kjeldahl <marius@funcom.com,
          mariusk@sn.no> for reporting this.

        * ace/config-linux-lxpthreads.h: Removed the _MIT_POSIX_PTHREADS
          symbol since we're using Xavier's threads instead.  Thanks to
          Marius Kjeldahl <marius@funcom.com, mariusk@sn.no> for reporting
          this.

Tue Jan 28 23:32:58 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/SString: Added hash() methods to each ACE String class so
          that we can use this with the new ACE_Hash_Set implementation of
          ACE_Map_Manager.

        * ace/ACE.h (ACE): Added a UNICODE version of hash_pjw() so that
          we can use it to hash ACE_WString.

        * ace/OS.i (thr_setprio): Fixed a typo that was left over from a
          previous change.  Thanks to Fred LaBar
          <flabar@fallschurch.esys.com> for reporting this.

        * apps/Gateway/Gateway/{proxy_config,consumer_config}: Added
          comments to these config files so they are easier to understand.
          Thanks to Chuck Gehr for motivating this.

        * apps/Gateway/Peer/Peer.cpp: Changed the name from connection_id_
          to proxy_id_, which is more accurate.

        * apps/Gateway/Peer/Peer.cpp: Added a destructor to Peer_Handler
          so that it can clean itself up properly when shutdown with a
          signal.  This fixes a nasty bug.

        * ace/config-win32-msvc4.x.h (ACE_HAS_MFC): By default, ACE now
          enables ACE_HAS_MFC.  This makes it possible to use
          AfxBeginThread() with the ACE_THR_AFX flag.

        * ace/OS.cpp: Fixed a typo in the call to ::AfxBeginThread()
          function.  Thanks to Karlheinz for reporting this.

        * apps/Gateway/Peer/Peer.cpp: Removed all uses of the Map_Manager
          from the Peer.  There's only ever one connection from a Gateway
          per-Peer, so what was this doing here anyway?!  It was causing
          problems due to multiple deletions, so removing it improves
          robustness of the tests.

        * ace/OS.i: Commented out the "extern char **_sys_siglist"
          definition since this was conflicting with the definition in
          Solaris.  If some platforms needs this, we'll need to add a
          specific #ifdef.

Tue Jan 28 21:57:45 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.{h,cpp}:  added ACE_OS::set_sched_params ().  It permits
          platform-independent setting of thread priorities and
          priority classes.  It is currently supported on Solaris,
          Win32, and VxWorks.

        * ace/Scheduling_Parameters.{h,i,cpp},
          ace/Thread_Priority.{h,i,cpp}, ace/Makefile:
          Added these two classes to support ACE_OS::set_sched_params ().

Tue Jan 28 12:42:39 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/ace.mdp: Added the "Using MFC in a Shared DLL" flags.

        * tests/test_config.h (ACE_INIT_LOG): Made this UNICODE safe.

        * tests/Pipe_Test.cpp (main): Added an iteration count to control
          the number of children created by the main process.

        * ace/Memory_Pool.cpp (init_acquire): cast this->minimum_bytes_ to
          size_t to avoid compiler warning if size_t is unsigned.

        * ace/OS.h: Added strncat to the OS class.

Tue Jan 28 09:13:00 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/ACE.cpp (ACE::ldfind),
          ace/Local_Name_Space_T.cpp,
          ace/Local_Token.cpp (ACE_TPQ_Entry::ACE_TPQ_Entry),
          ace/Log_Msg.cpp (ACE_Log_Msg::msg, ACE_Log_Msg::find),
          Memory_Pool.cpp (ACE_MMAP_Memory_Pool::ACE_MMAP_Memory_Pool),
          ace/Naming_Context.cpp (ACE_Naming_Context::open),
          ace/Parse_Node.cpp (ACE_Location_Node::open_handle),
          ace/Registry.cpp (ACE_Predefined_Naming_Contexts::is_local_host, 
                ACE_Registry::Binding_Iterator::Object_Iteration::next_n,
                ACE_Registry::Binding_Iterator::Context_Iteration::next_n),
          tests/UPIPE_SAP_Test.cpp:
          changed "sizeof char" to "sizeof (char)" because g++ and Sun C++
          (properly) choked on it.

        * ace/Local_Name_Space_T.cpp (create_manager_i):
          -- ::strncat () instead of ACE_OS::strcat ()
          -- "lock_name_for_backing_store" instead of
             "lock_name_for_local_name_space"

        * ace/Naming_Context.cpp (both constructors): reordered
          initializers to match declaration order.
 
        * include/makeinclude/platform_sunos5_g++.GNU: removed
          -fno-strict-prototypes because it's not needed with SunOS 5.5.1.

Mon Jan 27 21:33:00 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * tests/Naming_Test.cpp (main): Made modifications to the test to
          make it more dynamic.  Also made it work with UNICODE and
          ACE_Naming_Context.

        * ace/Local_Name_Space_T.cpp (create_manager_i): Added a better
          naming scheme for the locks.

        * ace: Changed the calculations of string lengths such that the
          size of the character type is carefully considered.

          The following were affected:
          
          ACE.cpp (ACE::ldfind)
          Local_Token.cpp (ACE_TPQ_Entry::ACE_TPQ_Entry)
          Log_Msg.cpp (ACE_Log_Msg::msg, ACE_Log_Msg::find)
          Memory_Pool.cpp (ACE_MMAP_Memory_Pool::ACE_MMAP_Memory_Pool)
          Naming_Context.cpp (ACE_Naming_Context::open)
          Parse_Node.cpp (ACE_Location_Node::open_handle)
          Registry.cpp (ACE_Predefined_Naming_Contexts::is_local_host, 
                ACE_Registry::Binding_Iterator::Object_Iteration::next_n,
                ACE_Registry::Binding_Iterator::Context_Iteration::next_n)
                        
        * ace/OS.h: Added UNICODE support for ACE_DEFAULT_LOCALNAME.

        * ace/Proactor.cpp: Redid "lost" changes to add UNICODE support to:

          /* Proactor */
          ACE_Overlapped_File::ACE_Overlapped_File
          ACE_Overlapped_File::open

        * ace/Registry_Name_Space.h: Changed the order of #include and
          #define as that the correct set of MACROS are defined for the
          include files.

        * tests/MM_Shared_Memory_Test.cpp: Added UNICODE support.
        
Mon Jan 27 09:16:03 1997  David L. Levine  <levine@cs.wustl.edu>

        * include/makeinclude/platform_sunos5_sunc++.GNU,
          include/makeinclude/platform_sunos5_sunc++_orbix.GNU,
          ace/config-sunos5.5-sunc++-4.x-orbix.h
          ace/config-sunos5.5-sunc++-4.x.h:
          disabled exception handling by commenting out ACE_HAS_EXCEPTIONS
          in the config files and adding -noex to the platform files,
          because it causes trouble, at least on MP machines.

Mon Jan 27 14:54:31 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Memory_Pool.h: Added code to ACE_MMAP_Memory_Pool_Options to
          take a minimum_bytes parameter.  This is needed to prevent mmap
          remapping when a large segment is requested.  Thanks to Fred
          LaBar <flabar@fallschurch.esys.com> for this.

Sun Jan 26 13:39:13 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.i: Changed the typo sis_siglist to sys_siglist.  Also,
          changed the logic from #if !defined (ACE_HAS_SYS_SIGLIST) to
          #if defined (ACE_HAS_SYS_SIGLIST) since this makes more sense...
          Thanks to Nanbor Wang <nw1@cs.wustl.edu> for noticing this.

Sat Jan 25 20:30:23 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-sunos5.5-sunc++-4.1.h: commented out ACE_HAS_EXCEPTIONS
          #define because -noex is required with it, and that causes core
          dump during thread exit on multiprocessor UltraSparcs.

        * include/makeinclude/platform_sunos5_sunc++_4.1.GNU: added -noex
          back because of core dump during thread exit on
          multiprocessor UltraSparcs.

        * examples/ASX/Event_Server/Event_Server/Event_Analyzer.cpp,
          examples/ASX/UPIPE_Event_Server/Event_Analyzer.cpp (control):
          added "default" case to switch statement to eliminate compiler
          warnings about enumeration values not being handled in switch.

        * examples/ASX/UPIPE_Event_Server/event_server.cpp (consumer):
          removed unused variable "iter".

Sat Jan 25 12:50:24 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.i: Updated all the cond_timedwait() and cond_wait()
          methods so that they decrement the count of waiters by one even
          when errors occur.  Thanks to Irfan for finding this.

        * ace/Map_Manager.cpp: Updated the ACE_Map_Iterator code so that
          it no longer crashes if the Map has been closed.  Thanks to
          Slawomir Kuzniar <kuzniar@Bear.COM> for reporting this.

Sat Jan 25 11:34:56 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

        * ace/SOCK_Connector.cpp (complete): Added a sleep of zero seconds
          which allows non-blocking connects to work properly on NT.

        * ace/config-winnt-4.0-msvc4.x.h and config-win32-msvc4.x.h: 
          Added ACE_HAS_BROKEN_NON_BLOCKING_CONNECTS.

        * ace/OS.i: Moved out all code for Time_Value from #if region. It
          is common to all.

        * ace/Reactor: Added helper routines to stop the VC++ compiler from
          bitching about destructors in exception handling code.

        * ace/ace.{mak,mdp}: Removed Time_Value.cpp from project.

        * tests/tests.{mak,mdp}: Corrected the creation of SOCK_Test and
          Message_Blob_Test executables and temporary files.

Fri Jan 24 09:01:50 1997  David L. Levine  <levine@cs.wustl.edu>

        * examples/Connection/misc/Connection_Handler.cpp: added
          specialization of ACE_Svc_Handler<ACE_SOCK_STREAM, ACE_NULL_SYNCH>
          so that subproject will build with g++ without optimization.

        * apps/Gateway/Gateway/Proxy_Handler.cpp: added specializations
          of ACE_Svc_Handler<ACE_SOCK_STREAM, ACE_SYNCH> and
          ACE_Svc_Handler<ACE_SOCK_STREAM, ACE_NULL_SYNCH>
          so that subproject will build with g++ without optimization.

        * tests/Reactor_Exceptions_Test.cpp (main): added ACE_UNUSED_ARG
          for argc and argv when ACE_HAS_EXCEPTIONS is not defined.

        * performance-tests/Misc/test_mutex.cpp: made destructor of
          Thread_Mutex_Derived virtual because the class has other virtual
          functions.

Thu Jan 23 11:51:45 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/config-sunos5.5-g++.h: commented out ACE_HAS_EXCEPTIONS because
          -fhandle-exceptions is broken in g++ 2.7.2 (and is required in order
          to use exception handling); also, added ACE_HAS_INLINED_OSCALLS, if
           __ACE_INLINE__ is #defined.

        * ace/config-sunos5.5-sunc++-4.1.h: added ACE_HAS_INLINED_OSCALLS,
          if __ACE_INLINE__ is #defined.

Wed Jan 22 15:04:47 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.h: Moved the ACE_TIMER_SKEW macro to below the #inclusion
          of config.h and updated it so that it can be overridden in the
          config.h file if necessary.  Thanks to Bob Olson
          <olson@mcs.anl.gov> for motivating this.

        * ace/OS.cpp: Fixed the implementation of
          ACE_Thread_ID::operator== so that it works correctly when thread
          ids and thread handles aren't ints.  Thanks to Chuck Gehr for
          reporting this.

        * ace/OS.i (thr_getprio): Moved a stray #else into the right
          place.  Thanks to Chuck Gehr for reporting this.

        * ace/OS.i (sema_post): this->count_++ should have been
          s->count_++.  Thanks to Chuck Gehr for reporting this.

        * ace/Synch_T.cpp: Added an extern "C" definition for
          ACE_TSS_C_cleanup().  Thanks to Chuck Gehr for reporting this.

        * ace: Added a new #define called ACE_LACKS_SYS_NERR to the
          config files for MVS and VxWorks.  This is used in OS.cpp
          as follows:

          #if defined (ACE_LACKS_SYS_NERR)
          int sys_nerr = ERRMAX + 1;
          #endif /* ACE_LACKS_SYS_NERR */

          Thanks to Chuck Gehr for reporting this.

        * Removed all #inclusions of "ace/Time_Value.h."  This file
          no longer contains anything besides a #include "ace/OS.h"
          and is only kept around due to backwards compatibility.

        * ace: Moved the contents of Time_Value.h into OS.h to reduce the
          confusion that arises from the #inclusion of "config.h" in
          Time_Value.h.  Also merged the contents of Time_Value.{i,cpp}
          into OS.{i,cpp}.  Thanks to the MDA guys for motivating this.

        * tests/Reactor_Exceptions_Test.cpp: Added a new test that
          exercises the Reactor with C++ exceptions.  Thanks to Luca for
          the test.

        * ace/Reactor.cpp (handle_events): Added Win32 structured
          exception handling support to the ACE_Reactor::handle_events()
          method so that it correctly releases the token lock when Win32
          SEH occur in callback routines.  Thanks to Luca for reporting
          this problem.

        * ace: Added a new macro called ACE_HAS_EXCEPTIONS, which
          indicates that the compiler supports C++ exception handling.

        * include/makeinclude/platform_sunos5_sunc++*.GNU: Commented out
          the -noex flag for now.  Hopefully, things will work correctly
          now.

        * ace/Thread_Manager.cpp (exit): Removed the final acquire() on
          ace_mon, which is no longer necessary since the Guard classes
          now keep track of whether they are "owned".  Thanks to Karlheinz
          and Detlef for this fix.

Wed Jan 22 09:05:31 1997  David L. Levine  <levine@cs.wustl.edu>

        * Makefile,VERSION: modified top-level Makefile (and VERSION)
          to add a timestamp to the VERSION file if creating a release
          from the /project/adaptive/ACE_wrappers directory.  If it
          causes problems, this will disable it:
          % make  TIMESTAMP=  release.

        * ace/Local_Tokens.cpp (dump): replaced "ACE_TSS<ACE_TPQ_Entry>"
          with "ACE_TPQ_ENTRY" so that ACE_NO_TSS_TOKENS is supported.

        * ace/Synch.h: fixed typo in comment header for ACE_Thread_Semaphore

        * ace/config-vxworks-ghs-1.8.h,config-vxworks5.2-g++.h,
          config-unixware-2.01-g++.h:
          protect ACE_HAS_INLINED_OSCALLS #defined with
          #if defined (__ACE_INLINE__).

        * apps/Gateway/Gateway/Event_Channel.cpp (open): added
          ACE_UNUSED_ARG (sig);.

        * examples/ASX/Event_Server/Event_Server/Peer_Router.h:
          declared a friend of class Peer_Router_Context because it
          has a private destructor, to eliminate compiler warning
          about not having any friends.

        * examples/ASX/Event_Server/Event_Server/Supplier_Router.cpp
          (open): added return 0 in "true" branch of if statement so
          that the function always returns a value.

Tue Jan 21 09:19:44 1997  David L. Levine  <levine@cs.wustl.edu>

        * tests/Reader_Writer_Test.cpp (reader): commented out unused
          variable "n"; also, commented out unused function
          print_usage_and_die.

        * tests/TSS_Test.cpp, Thread_Manager_Test.cpp (main): added
          ACE_UNUSED_ARG (sa);.

        * tests/Thread_Pool_Test.cpp (open):  added return 0 at end.

Tue Jan 21 11:00:12 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * apps/Gateway/Gateway/Gateway.cpp (parse_args): There was a small
          bug in parse_args (latest beta), it mixed proxy and consumer
          conf files.  Thanks to Per Andersson
          <Per.Andersson@hfera.ericsson.se> for reporting this.

Mon Jan 20 13:29:28 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.i, ace/Task.h, and ace/Thread_Manager.h: changed a few
          occurrences of NULL to 0 (for other than Win32 platforms),
          primarily to avoid compiler warnings on VxWorks if ACE.h isn't
          #included before stddef.h.

        * netsvcs/clients/Naming/Dump_Restore/Dump_Restore.cpp
          (handle_input): replaced %d format with %hu for u_short arg.

        * netsvcs/clients/Tokens/deadlock/deadlock_detection_test.cpp
          (run_writer): initialized variable "t" to avoid compiler warning.

        * examples/Connection/misc/Connection_Handler.cpp (handle_timeout):
          added ACE_UNUSED_ARG (tv); also, added explicit int return type
          to definition of Connection_Handler::close (u_long).

        * examples/Threads/task_four.cpp (Invoker_Task::svc):
          moved declaration of "task" out of for loop because it is
          also used after the for loop.

        * netsvcs/lib/Name_Handler.cpp, Server_Logging_Handler.cpp,
          TS_Clerk_Handler.cpp, TS_Server_Handler.cpp, Token_Handler.cpp:
          added ACE_UNUSED_ARG (sig);.

Sun Jan 19 11:10:49 1997  David L. Levine  <levine@cs.wustl.edu>

        * include/makeinclude/platform_sunos5_sunc++.GNU,
          platform_sunos5_sunc++_4.1.GNU:
          added comment about compiler warnings with +w option.
          Also, added +w to platform_sunos5_sunc++_4.1.GNU.  With the
          other changes in this ChangeLog entry, there no longer should
          be significant warnings from Sun C++ when building ACE.

        * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp
          (Peer_Handler::put): added ACE_UNUSED_ARG (tv);.

        * examples/IPC_SAP/SPIPE_SAP/NPServer.cpp (main),
          netsvcs/clients/Tokens/invariant/invariant.cpp (main):
          commented out argc and argv.

        * examples/Mem_Map/file-reverse/file-reverse.cpp (main):
          removed unused variable "cp".

        * netsvcs/clients/Tokens/manual/manual.cpp (handle_input,
          handle_exception): added ACE_UNUSED_ARG (fd); and
          (create_proxy): added return statement at end:  even
          though it should never be reached, it eliminates a
          compiler warning.

        * examples/OS/Process/process.cpp,
          examples/Reactor/Misc/test_reactors.cpp,
          netsvcs/clients/Tokens/deadlock/deadlock_detection_test.cpp,
          netsvcs/clients/Tokens/mutex/test_mutex.cpp,
          netsvcs/clients/Tokens/rw_lock/rw_locks.cpp,
          performance-tests/TTCP/ORBeline/ttcp_i.cpp,
          performance-tests/TTCP/Orbix/ttcp_i.cpp (main):
          return 0 instead of 42.

Sat Jan 18 10:54:25 1997  Prashant Jain  <pjain@merengue.cs.wustl.edu>

        * java/src/README: Updated the README file to indicate how
          documentation for Java ACE cab be automatically generated.

Fri Jan 17 11:47:10 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/OS.h: Added an equivalent set of
          ACE_LSOCK_{STREAM,ACCEPTOR,CONNECTOR} macros to complement the
          ones for ACE_SOCK_*.  Thanks to Gonzalo Diethelm
          <gonzo@ing.puc.cl> for suggesting this.

        * ace/OS.cpp (ACE_Thread_Adapter): Added a new feature that allows
          logging features to be inherited by threads.  It works with
          those OSs (e.g., Win32) that use ACE_Thread_Adapter class.  At
          some point, we might do this for all the OSs.  Thanks to Luca
          for this.

        * examples/Connection/misc/Connection_Handler.cpp: Added a
          new example that illustrates how to use the Acceptor pattern
          to create multiple threads, each running its own Reactor.

        * ace/Log_Msg.cpp (dump): Some of the variables in the dump()
          method have the wrong format specification type. These are:
          restart_ (%d), flags_ (%x), priority_mask_ (%d).  They are now
          fixed, thanks to Luca.

        * tests/Priority_Task_Test.cpp (open): Add an ACE_ASSERT to make
          sure that the tasks activate() correctly.  Thanks to David for
          finding this.

        * ace/config-linux-lxpthreads.h: Added #defines for
          ACE_HAS_AUTOMATIC_INIT_FINI and ACE_HAS_SVR4_DYNAMIC_LINKING.
          Thanks to Marius for this.

        * ace/Malloc.h: Changed the typedef of ACE_Malloc_Align to a macro
          called ACE_MALLOC_ALIGN to allow users to override this value in
          their config.h file.  This is necessary for platforms that don't
          have "long" word alignments.  Thanks to Fred LaBar
          <flabar@fallschurch.esys.com> for this suggestion.

        * ace/OS.h: Added an #ifdef check for ACE_HAS_IRIX62_THREADS and
          if so, we'll use the if (&a) /* null */; } form of the
          ACE_UNUSED_ARG macro to avoid unnecessary warnings.  Thanks to
          Fred LaBar <flabar@fallschurch.esys.com> for testing this out.

Fri Jan 17 16:33:25 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/High_Res_Timer.*: added elapsed_time () and get_time ().

        * netsvcs/clients/Tokens/collection/collection.cpp, rw_locks.cpp:
          commented out unused variables to avoid compiler warnings; and
          return 0 from main ().

        * include/makeinclude/rules.local.GNU,
          netsvcs/lib/Makefile,
          examples/Service_Configurator/IPC-tests/server/Makefile:
          fixed ESOBUILD mechanism to work on all platforms, not just Linux.
          Thanks to Marius Kjeldahl <marius@funcom.com> for this fix.

        * ace/OS.i and OS.cpp: uninlined functions that use varargs, because
          they usually won't get inlined anyways.

        * ace/OS.cpp (thr_create): added #else clause to be sure that
          always sparam.sched_priority always get set to the priority argument.

        * netsvcs/clients/Naming/Client/Client_Test.cpp: commented out
          unused parameters and wrapped combined assignments/conditional
          values to avoid compiler (g++) warnings.

        * tests/Priority_Task_Test.cpp: added check for successful thread
          spawn, and ACE_NEW_THREAD to svc () so that messages get logged.

Thu Jan 16 17:03:47 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * include/makeinclude: Added support for shared object files
          on Linux.  Thanks to Marius Kjeldahl <mariusk@sn.no,
          marius@funcom.com> for his help with this. 

        * ace: Merged in the IRIX support, mainly the missing netdb reentrant 
          functions.  Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl>
          and Carlos O'Ryan <coryan@mat.puc.cl> for their help.

        * ace/Timer_{List,Heap,Queue}: Changed iterator() to iter() to
          avoid name clashes with STL (ugh).

        * ace/Timer_{Heap,List}.cpp: Added ACE_BUILD_DLL so that things
          will link.  Thanks to John Morey for reporting this.

        * ace/Synch_T.h: Fixed: class ACE_Write_Guard: method:
          tryacquire_write so that it will call
          ...->lock_->tryacquire_write() and not
          ...->lock_->acquire_write().  Thanks to Alexandre Karev
          <Alexandre.Karev@cern.ch> for this fix.

Thu Jan 16 15:51:16 1997  David L. Levine  <levine@cs.wustl.edu>

        * Dump.cpp (register_object): initialized "slot" so that g++ doesn't
          complain about uninitialized use.

        * Reactor.cpp (initialized): use ACE_GUARD_RETURN instead of
          ACE_GUARD because the function returns a value;
          (find): initialize "i" if handle is out of range so that g++
          doesn't complain about uninitialized use.

        * Service_Repository.cpp (remove): removed unused variable "handle".

        * Thread_Manager.h: made destructor virtual now that spawn_i () is
          virtual.

        * Timer_Heap.cpp: changed some int loop indicies to size_t to
          make sure that comparisons are consistently signed or unsigned.

        * OS.h, config-vxworks*.h: removed ACE_HAS_GREENHILLS_SOCKETS
          ACE macro because the code it wrapped applies to all VxWorks
          compilers, not just GreenHills.

Wed Jan 15 02:06:21 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/ACE.cpp (round_to_pagesize): If _SC_PAGESIZE is enabled then
          we set the ACE::pagesize_ variable using sysconf(2).  Thanks to
          James Mansion for this suggestion.

Wed Jan 15 02:06:21 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Timer_Queue.cpp (expire): Changed a line of code from
        
          ACE_Timer_Queue_Iterator &iterator (this->iterator ());

          to

          ACE_Timer_Queue_Iterator &iterator = this->iterator ();

          so that the Visual C++ compiler can grok it.  Thanks to John
          Morey for reporting this.

        * ace/Reactor.cpp: Modified the close() method so that it can be
          called multiple times with no bad side-effects.

        * ace/Pipe.cpp: Modified the close() method so that it can be
          called multiple times with no bad side-effects.

        * ace/Reactor: Added an initialized() method that indicates
          whether the Reactor was successfully initialized.  Also
          rearranged the code in ACE_Reactor::open() so that initialized_
          is only set at the end of the method when everything succeeds.
          If things *don't* succeed, we call close() on the way out.
          Thanks to Luca for these suggestions.

        * ace/Reactor.cpp (close): When closing down the ACE_Reactor, we
          now set initialized_ back to 0 so that it can be reopened again
          later.

        * tests/Reader_Writer_Test.cpp: There were some problems with this
          test due to the fact that on many pthreads platforms pthread_t
          isn't an int (it's a struct).  Thanks to Chuck Gehr
          <gehr@sweng.stortek.com> for the fix.

        * ace/OS.i (exit): In WIN32 when the process exits through an
          ExitProcess() call, some process resources (e.g., file handles)
          are freed before the static variable destructors are
          called. This results in an application error when tracing is
          enabled.  Removing the ACE_TRACE call in ~ACE_Event_Handler
          seems to fix this.  Thanks to Luca for this fix.

        * ace/OS: Fixed the implementation of semaphores for the POSIX
          port (POSIX lacks semaphores).  The trick was to add a "waiters"
          field, along with the semaphore count.  Thanks to John Bossom
          <John.Bossom@Cognos.COM> for reporting this.

        * examples/Threads/wfmo.cpp: Added a new test program that seems
          to indicate that the Win32 WaitForMultipleObjects() function can
          be called in multiple threads, all of which wait on the same set
          of HANDLEs.  Note that the dispatching of the threads is
          relatively "fair" (i.e., everyone gets a chance to process the
          various HANDLEs as they become active).  Thanks to Ari Erev
          <Ari_Erev@comverse.com> for suggesting this and providing the
          initial code.

        * ace/Thread_Manager.h: Made the spawn_i() method virtual and
          moved it into the protected section of the class so that it can
          be over-ridden by subclasses.  Thanks to Tim Harrison for
          suggesting this.

Tue Jan 14 15:57:55 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/OS.h: Changed the default size of ACE_DEFAULT_TIMERS to
          _SC_TIMER_MAX (which is typically around 40 or so).
          Thanks to Stuart Powell <stuartp@in.ot.com.au> for
          suggesting this.

        * tests/Timer_Queue_Test.cpp (main): Added some additional logic
          so that we can test the performance of the preallocated and
          non-preallocated ACE_Timer_Heap.

        * ace/Timer_Heap: Added a new "preallocate nodes" mechanism to the
          ACE_Timer_Heap.  If this is enabled by the constructor, then we
          preallocate as many ACE_Timer_Nodes as there are slots in the
          heap.  This allows us to completely remove the need for dynamic
          memory allocation, which is important for real-time systems.

        * ace/Thread_Manager.cpp (remove_thr): Optimized the code just a
          tad by decrementing the current_count_ *first*.  Thanks to Per
          Andersson <Per.Andersson@hfera.ericsson.se> for suggesting this.

        * ace/ReactorEx: Updated the implementation so that the
          handle_events() method now in fact *does* return the number of
          event handler's dispatched (i.e., the implementation matches the
          documentation...).  Thanks to Hamutal Yanay
          <Hamutal_Yanay@mail.icomverse.com> for reporting this.

        * ace/Service_Repository.cpp (remove): Removed an extra call to
          ACE_OS::dlclose().  This is already being called in the
          destructor of ACE_Service_Record.  Thanks to Karlheinz for
          reporting this.

        * man: Updated all the nroff and html documentation.

        * ace/Timer_Heap: Implemented the spiffy new timer cancellation
          algorithm that requires only O(log N) time to remove a timer
          from the ACE_Timer_Heap.  This is about 50 to 100 times faster
          than using the ACE_Timer_List implementation.

Tue Jan 14 21:01:36 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: Replace "Linux" preprocessor symbol with "linux".

Mon Jan 13 17:57:50 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Synch: Added lock() accessor methods to both
          ACE_Process_Semaphore and ACE_Process_Mutex.  Thanks to Hamutal
          Yanay <Hamutal_Yanay@mail.icomverse.com> for suggesting this.

        * ace/config-mvs.h: Added a #define for ACE_HAS_GETPAGESIZE.
          Thanks to Chuck Gehr for this information.

        * ace/LSOCK_Stream.h: Added a new typedef for PEER_ADDR that is
          associated with ACE_UNIX_Addr.  Thanks to Mark Rabotnikov
          <mark@usp.elscintcorp.co.il> for suggesting this.

Mon Jan 13 22:24:09 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/OS.h: Added #undefs of sigemptyset and sigfillset on Linux
          when __OPTIMIZE__ is enabled.  Yes, the system header on Linux
          really #defines them when optimizing!  Thanks to an anonymous
          ACE user for pointing this out.

        * tests/tests_config.h: Dropped ACE_MAX_ITERATIONS back to 10.

Sun Jan 12 16:59:52 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/Timer_List.cpp (schedule): Cleanup the code so that (1)
          timer_id never == -1 (in order to distinguish it from error
          return values and (2) so that we avoid an unnecessary check for
          operator new failure.

        * ace/OS.h: Added a new #define called ACE_DEFAULT_MAX_TIMERS,
          which specifies the maximum number of ACE_Event_Handlers
          supported by ACE_Timer_Heap.

        * ace/Proactor.cpp (ACE_Proactor): Updated the allocation of
          ACE_Timer_Queue so that it really points to an ACE_Timer_List by
          default.  Naturally, this can be overridden by users.

        * ace/ReactorEx.cpp (open): Updated the allocation of
          ACE_Timer_Queue so that it really points to an ACE_Timer_List by
          default.  Naturally, this can be overridden by users.

        * ace/Reactor.cpp (open): Updated the allocation of
          ACE_Timer_Queue so that it really points to an ACE_Timer_List by
          default.  Naturally, this can be overridden by users.

        * ace: Added two new classes called ACE_Timer_List and
          ACE_Timer_Heap, which derive from ACE_Timer_Queue.
          ACE_Timer_List is essentially the old behavior of
          ACE_Timer_Queue, i.e., it uses an implementation of a linked
          list of ACE_Timer_Nodes.  ACE_Timer_Heap, on the other hand,
          uses a heap-based callout queue, which is more appropriate for
          certain real-time applications.

        * ace/Timer_Queue: Revised the ACE_Timer_Queue implementation so
          that it's now an abstract base class with most of the
          implementation details pushed into the ACE_Timer_List and
          ACE_Timer_Heap subclasses.

        * ace/Timer_Queue.h: Made all the ACE_Timer_Queue methods public
          so that we can override them in a subclass (e.g., the new
          ACE_Timer_Heap).

        * examples/Logger/Acceptor-server/server_loggerd.cpp: Fixed this
          example application so that it only uses a single Reactor (the
          REACTOR::instance()) rather than two Reactors.  Thanks to Sandro
          Doro <alex@aureus.sublink.org> for reporting this.

        * netsvcs/lib/Logging_Strategy.cpp: Fixed the #include of
          fstream.h and iostream.h to use the '<' '>' notation rather than
          the '"' and '"' notation.  This avoids problems with running
          "make depend".  Thanks to Rino Simioni <sir@necsy.it> for
          reporting this fix.

Sun Jan 12 18:20:49 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/ACE.cpp (round_to_pagesize): fixed typo in reference to
          ACE::pagesize_.

        * ace/ACE.cpp: initialize ACE::pagesize_ to 0.

        * ace/config-irix*.h and config-win*.h: removed ACE_PAGE_SIZE
          definition because these platforms no longer use it.

        * tests/UNIX*.conf and Win32server.conf:  replaced net_svcs
          with netsvcs.

Sat Jan 11 15:11:28 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * ace/OS.i (thr_setprio): The POSIX implementation of
          ACE_OS:thr_setprio did not set the priority.  It calls:

          pthread_setschedparam( thr_id, &policy, &param )
 
          and then does
 
          prio = param.sched_priority.
 
          instead of

          param.sched_priority = prio;
          
          This is now fixed.  Thanks to John Bossom <John.Bossom@Cognos.COM>
          for reporting this.

        * ace/config-irix*.h: Modified all the IRIX config files to
          use the new ACE_HAS_GETPAGESIZE feature since this is necessary 
          to differentiate between IRIX and IRIX64.
          Thanks to Fred LaBar <flabar@fallschurch.esys.com> for
          reporting this.

        * ace/ACE.cpp: Modified the round_to_pagesize() so that if
          a config.h file enables ACE_HAS_GETPAGESIZE then we use
          that function in preference to the value in config.h.
          Thanks to Fred LaBar <flabar@fallschurch.esys.com> for
          suggesting this.

        * ace/ACE.cpp: Modified the round_to_pagesize() so that on
          platforms that allow the page size to be obtained dynamically
          we'll get that rather than replying on what it set in the
          config.h file.  We'll cache this value in a static variable
          to speedup searches.  Thanks to James Mansion for suggesting
          this.

        * apps/Gateway/Gateway: Finished adding support for thread-safe
          reference counting to the uses of ACE_Message_Block.

        * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: Replaced
          the use of ACE_MT_SYNCH with ACE_SYNCH so that this will compile
          correctly on non-MT platforms.

Fri Jan 10 12:38:42 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

        * Added a COPYING file that explicitly states the copyright status
          of ACE.

        * ace/config-win32-msvc4.x.h and ace/config-winnt-4.0-msvc4.x.h:
          By default, we'll revert to *not* enabling
          ACE_HAS_TEMPLATE_TYPEDEFS for MSVC++ 4.2, even though this is
          well-support by the compiler since it breaks some application
          code that expects to use 3 template parameters for
          ACE_Svc_Handler<>.  The "fix" is to use the ACE_SOCK_STREAM
          macros (rather than using the "ACE_SOCK_Stream, ACE_INET_Addr"
          tuple) in order to achieve portability in either case.  Thanks
          to Karlheinz for pointing out the need for backwards
          compatibility.

Wed Jan  8 01:00:05 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * tests/Message_Block_Test.cpp: Enhanced the torture test of the
          ACE_Message_Block so that it stresses the reference counting
          implementation in a multi-threaded environment.

Wed Jan 08 10:26:45 1997  David L. Levine  <levine@cs.wustl.edu>

        * ace/Message_Block.cpp (~ACE_Data_Block): assigned 0 to
          allocator_strategry_ after deleting it; fixed template
          specializations (for g++) by using macros instead of class names;
          commented out template specializations because Service_Record.cpp
          already has them, and they should only appear once in the library
          in order to avoid link clashes

        * ace/Service_Object.cpp (ACE_Service_Object): reordered
          initializations in constructor

        * ace/Service_Record.cpp (ACE_Service_Record): reordered
          initializations in constructor

        * ace/config-linux-lxpthreads.h:  added
          ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS, thanks to
          James CE Johnson <jcej@lads.com> for tracking down this
          problem and testing the fix.

Tue Jan  7 13:03:25 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Message_Block: Continued to improve the
          ACE_Message_Block/ACE_Data_Block implementation.

        * ace/Message_Block: Added a new constructor to ACE_Message_Block
          that takes an ACE_Data_Block * and "owns" it.  Thanks to Tim for
          this idea.

        * ace/Log_Msg.cpp: Now that we've prevented signal handlers from
          occurring within critical sections of ACE_Log_Msg::log() we
          don't need to use the ACE_Recursive_Thread_Mutex anymore.
          Instead, we just need ACE_Thread_Mutex.

        * ace/Log_Msg.cpp (log): Added an ACE_Sig_Guard to the block in
          ACE_Log_Msg::log() that acquires the mutex that serializes
          output.  This prevents nasty problems with recursive to
          ACE_Log_Msg::log() from within signal handlers.

        * ace/Service_Config.cpp (end_reactor_event_loop): Added a timeout
          of ACE_Time_Value::zero to the ACE_Reactor::notify() method when
          called in the ACE_Service_Config::end_reactor_event_loop().
          This prevents the Reactor from blocking indefinitely if there's
          no longer a thread to receive from the notification pipe.
  
        * netsvcs/clients/Naming/Dump_Restore: Removed the vestigal
          nametest.cpp and nametest.h files.  I'm not sure why they were
          still there, but they shouldn't have been!

        * ace/Synch.i (remove): this->owner_ should be set to -1 before
          calling this->release().  Thanks to Per Andersson
          <Per.Andersson@hfera.ericsson.se> for suggesting this.

        * ace/Thread_Manager.cpp (exit): Added a flag called "do_thr_exit"
          to the ACE_Thread_Control::exit() method.  This controls whether
          we call ACE_OS::thr_exit() after removing the thread from the
          Thread Manager's internal table.  This is necessary to work
          around pthread bugs on certain platforms (e.g., AIX and Linux).

        * ace/Synch.h: Removed the
          ACE_Recursive_Thread_Mutex::set_nesting() method since this
          isn't being used and is potentially dangerous.  Thanks to Per
          Andersson <Per.Andersson@hfera.ericsson.se> for suggesting this.

        * ace/XtReactor: Updated the XtReactor so that it uses the next
          internal Reactor implementation.  Thanks to Mark Rabotnikov
          <mark@usp.elscintcorp.co.il> for reporting this.

        * ace/Task.i: Updated the grp_id(int) method to cache the group id
          in the task and then set it in the Thread_Manager, if there is
          one.  Thanks to Hamutal Yanay <Hamutal_Yanay@mail.icomverse.com>
          for suggesting this.

        * ace/Log_Record.h: Updated the ACE_Log_Record class to use the
          new ACE_MAXLOGMSGLEN macro.

        * ace/OS.h: Added a new #define called ACE_MAXLOGMSGLEN.  By
          default this is 4k.  However, you can reset it in the config.h
          file if you'd like to increase or decrease the size.  Thanks to
          Anthony McConnell for suggesting this.
          
        * examples/Threads/tss[12].cpp: Tidied up the tss1.cpp and
          tss2.cpp examples and improved the comments.  Thanks to Luca for
          suggesting this.

        * ace/Service_Object.cpp (fini): Added the "virtual" keyword to
          the new destructor of ACE_Service_Type.  Thanks to David for
          reporting this.

        * ace/Message_Block.i: Rearranged the order of the ACE_Data_Block
          and ACE_Message_Block locking_strategy() methods so that they'd
          be defined as inline before being used.  Thanks to David for
          reporting this.

Mon Jan  6 16:46:06 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Service_Manager.cpp (fini): Only try to remove the
          ACE_Service_Manager from the Reactor if it's actually been
          registered in the first place (i.e., if it's get_handle() method
          does not return ACE_INVALID_HANDLE).

        * netsvcs/servers/svc.conf: Changed the name of the net services
          .so file from libnet_svcs to netsvcs so that it will work
          correctly with our new "cross-platform" svc.conf ACE::ldfind()
          strategy.  Thanks to Marius Kjeldahl <marius@funcom.com> for
          reporting this.

        * ace/Reactor.cpp (find): Added a strategic break and a check for
          handle_in_range().  Thanks to Tim for this help!

        * netsvcs/clients/Naming/Client/svc.conf: Removed the "lib" part
          from the executable shared object file names in the svc.conf
          file so that it will work with the new "cross-platform" svc.conf
          ACE::ldfind() strategy.  Thanks to Marius Kjeldahl
          <marius@funcom.com> for reporting this.

        * ace/Service_Record.cpp (fini): Added an extra assignment to a
          temporary const void *obj to avoid problems with MSVC++ and it's
          cast mechanism.

        * ace/ReactorEx.h: Added a default parameter to
          ACE_ReactorEx::notify().  Thanks to Tim for noticing this.

Sun Jan  5 10:48:23 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * tests: Added a new test for ACE_Message_Block, which is called
          Message_Block_Test.cpp (no surprise there ;-)).  This test
          exercises the reference counting mechanisms.

        * ace/Message_Block.h: Made the destructors for ACE_Message_Block
          and ACE_Data_Block virtual, so that these classes can be
          subclassed and ACE_Message_Blocks can delete these
          subclasses (either via release() or delete).  Thanks to Tilo
          Christ for suggesting this.

        * ace/Message_Block.cpp: Modified the implementation
          of ACE_Message_Block/ACE_Data_Block so that we always create
          an allocator_strategy_.  By default, this strategy will be
          ACE_Allocator_Adapter <ACE_Malloc <ACE_Local_Memory_Pool, ACE_Null_Mutex> >;
          This greatly simplifies the code.

        * ace/Message_Block.h: It's now possible to assign a
          Message_Block's priority when you create it.

        * ace/Reactor: Sped things up some more by merging the Reactor's
          any_ready() and fill_in_ready() methods together.  This reduces
          redundant computations.

        * ace/Reactor: Changed the name of ACE_Reactor::detach() to
          ACE_Reactor::remove_handler_i() and changed the name of
          ACE_Reactor::attach() to ACE_Reactor::register_handler_i().
          This is more consistent with the other naming schemes.

        * ace/Reactor.cpp: Reworked the implementation of the Handler
          Repository's unbind() method in order to simplfy the logic.
          Also merged in all the Reactor's detach() functionality into the
          unbind() method in order to localize all the handler removal
          processing.

        * ace/Reactor[Ex].cpp: Added more descriptive errno entries for
          failed operations in the handler repository.

        * ace/Reactor.cpp: Modified the implementation of the Handler
          Repository's bind() method so that it reports an error if you
          try to register an Event_Handler for an invalid HANDLE.

        * ace/Reactor.cpp: Reimplemented the internals of the Reactor to
          prepare for the upcoming merge of the Reactor and ReactorEx to
          use a single code base.

        * ace/Timer_Queue.cpp: Modified the behavior of the expire()
          methods so that they return the number of ACE_Event_Handlers
          whose handle_timeout() method was called.

Sat Jan  4 11:47:05 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Reactor.h: Removed the #ifdefs for ACE_HAS_POLL.  This will
          be recast as a strategy in subsequent implementations.

        * ace/Reactor.cpp: Added a new call,
          ACE_Handler_Repository::handle_in_range(), which checks to make
          sure that the HANDLE is within the range of 0 .. max_handlep1_.
          This factors out some redundant code.

        * ace/Reactor.cpp: Sped up the performance of the Reactor by
          removing redundant calls to
          ACE_Handler_Repository::invalid_handle() and
          ACE_Handler_Repository::find().

        * tests/Reactors_Test.cpp: Added a test for
          the new Reactor::notify() method with timeouts.

        * examples/Reactor/Misc/notification.cpp (svc): Added a test for
          the new Reactor::notify() method with timeouts.

        * ace/Reactor[Ex]: Modified the Reactor and ReactorEx so that they
          use timed send() operations for their notify() methods.  This
          makes it possible for users to bound the amount of time they're
          willing to wait to try and notify the Reactor.  This is mostly
          useful to avoid infinite blocking if there is congestion in the
          Reactor's notification mechanism.

        * ace/ACE.cpp: Added a new timed send() method that uses the
          write() system call on UNIX and the socket send() call on Win32.
          This new method is used in the new ACE_Reactor::notify() method,
          which now supported timed notifications.

        * ace/Reactor.cpp (ACE_Handler_Repository): To simplify the code
          and reduce unnecessary #ifdefs, I've merged the max_handlep1_
          and cur_size_ fields (which are now called max_handlep1_).

Fri Jan  3 10:47:15 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace: Replaced all uses of "delete mb" with mb->release ();

        * ace/Stream_Modules.cpp: Replaced the use of explicit bit
          twiddling with the ACE_BIT* macros.

        * ace/Message_Block.cpp: Make sure that we use the
          allocator_strategy_ to create the memory for the reference count
          since this may need to go into shared memory if that's the
          memory pool where the Message_Block allocations are coming from.

        * ace/OS.h: Added two new macros, ACE_ALLOCATOR_RETURN and
          ACE_ALLOCATOR, which are similar to ACE_NEW_RETURN and ACE_NEW, 
          except that these

        * ace/Message_Block.cpp (release): Make sure to "delete this"
          outside the scope of the locking_strategy_.

        * ace/Service_Object.cpp: Added a destructor to ACE_Service_Type.
          Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for
          suggesting this.

        * ace/Service_Object.i: Be smarter about how we reassign the name_
          pointer, i.e., delete the old one and make a copy.  Thanks to
          Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting
          this.

        * ace/Module.cpp (open): Rearranged the assignments to
          reader_q->mod_ and writer_q->mod_ so that we don't try to
          initialize through NULL pointers.  Thanks to
          Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting
          this.

        * ace/Service_Record.cpp (ACE_Service_Record): Initialized name_
          to NULL so that the following change works correctly now.
          Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for
          reporting this.

        * ace/Service_Record.i (name): Make sure to delete [] (char *)
          this->name_ before allocating a new one.  Thanks to
          Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting
          this.

        * ace/Message_Block: Reworked the reference counting implemention
          so that reference counts are shared correctly amongst their
          various owners.  This requires making a deep copy the "header"
          portion, but a shallow copy of the "data."

        * ace/Message_Block.cpp (ACE_Message_Block): Updated all three
          ACE_Message_Block constructors so that they all call the init()
          method.  This centralizes all the initialization logic in one
          place.

        * ace/Message_Block.cpp (ACE_Message_Block): Make sure to set the
          cont_ field to 0 after "releasing" it so that we don't
          mistakenly think it's still around later on.  This problem arose
          in the ACE_Message_Queue::close() method, which was trying to
          count the number of bytes being freed.

        * ace/Message_Queue.cpp (close): Fixed a subtle bug where we
          weren't actually deleting messages from the
          ACE_Message_Queue::close() routine.  This should work now...

        * ace/Message_Queue.cpp (close): Replaced the use of "delete mb"
          with "mb->release()" since the Message_Blocks are now reference
          counted.  

        * ace/Message_Block: Enhanced the reference counting scheme so
          that you can increment and decrement the count by an arbitrary
          amount.  This is particular useful when you know you'll be
          sending the same Message_Block to N consumers.

        * ace/Singleton: The dump() must be used same as instance()
          (without supplying an object) so it must be declarated *static*,
          i.e.,

          static void dump (void);

          Thanks to Sandro Doro <alex@aureus.sublink.org> for reporting
          this.

        * examples/ASX/Event_Server: Completely rewrote and retested the
          ACE Event Server example.  The new code is *much* easier to
          understand, has many more comments, is more robust, and compiles
          much faster since I removed many of the templates.

        * examples/ASX/Event_Server/Tranceiver/tranceiver.cpp: Fixed the
          tranceiver so that it shuts down correctly when the Event_Server
          exits.

        * examples/Connection/non_blocking/CPP-connector.cpp: Fixed a
          problem where we were trying to select() on ACE_STDIN on Win32.
          Naturally, this doesn't work, so we used the
          ACE::register_stdin_handler() to fix this.  Thanks to
          Samuel_Bercovici <Samuel_Bercovici_at_EFT__AD2@mail.icomverse.com>
          for reporting this.

        * examples/ASX/Event_Server/Event_Server/Options: Changed the
          Options class to be a Singleton...

        * ace/Task.h: Added "const" method qualifier to accessor methods
          like is_reader() and is_writer().

Wed Jan  1 00:10:47 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * ace/Message_Block: Added a new static release() method that
          behaves like the non-static method release(), except that it
          checks if <mb> is 0.  This is similar to CORBA::release(), which
          is useful if you want to eliminate lots of checks for NULL
          pointers before calling release() on them.

        * Updated all places in ACE where we use
          ACE_Event_Handler::READ_MASK when we should be using
          ACE_Event_Handler::ACCEPT_MASK.

        * examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp:
          Changed the name of the acceptor class from Handle_Thr_Stream to
          Handle_Thr_Acceptor, which is more accurate.

        * ace/Reactor: Since we've now got an
          ACE_Event_Handler::ACCEPT_MASK (intended primarily to accept
          connections asynchronously using Win32 overlapped I/O) we can
          now use this with the ACE_Reactor, as well.  In particular, any
          time that we are registering a "passive-mode" socket acceptor we
          can now specify ACE_Event_Handler::ACCEPT_MASK.  This is much
          more intuitive than using the READ_MASK (which never made any
          sense...).  The ACE_Reactor now treats the ACCEPT_MASK as a
          READ_MASK internally, so you can still use READ_MASK if you'd
          like (i.e., this change doesn't break any existing code).

        * ace/Event_Handler: Changed "get_priority" and "set_priority" to
          simply "priority(void)" and "priority(int)" to be more
          consistent with other parts of ACE.

        * apps/Gateway/Gateway: Updated the Gateway so that the
          concurrency strategies can now be specified on the
          command-line (or in the svc.conf file), rather than being
          determined at compile-time.  This is much more flexible.
          See the ./apps/Gateway/Gateway/README file for details.

        * apps/Gateway/Gateway: Verified that all the multi-threading
          strategies still work.

        * ace/Message_Block.cpp (ACE_Message_Block): Make sure that we
          "release" the continuation field, rather than delete it, since
          its reference count may be > 1.

        * ace/Log_Msg.cpp (log): Change the abort_prog logic a bit so that
          we always print a message to stderr if we're exiting,
          regardless...  Thanks to David Levine for pointing this out.

        * apps/Gateway/Gateway: Moved all of the configuration file
          parsing logic *outside* of the Event_Channel into the Gateway
          class so that we wouldn't have unnecessary dependencies.

        * apps/Gateway/Gateway: Redesigned the Gateway so that the
          Proxy_Handlers (i.e., the Consumer_Proxy and Supplier_Proxy)
          most of their work to the Event_Channel.  This "lightweight
          proxy" design is an improvement since it is now possible to
          emulate the COS Event Channel semantics within the Event_Channel
          "kernel."

        * Happy new year!  Let's start a new ChangeLog to celebrate the
          new year.
