Sun Jun 30 15:28:43 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.i (cond_timedwait): Fixed the implementation of the
	  ACE_OS::cond_timedwait() wrapper such that if the
	  caller-specified timeout elapses without the condition variable
	  being signaled that errno is always set to ETIME.  This fixes
	  some inconsistencies that occurred with POSIX pthreads and Win32
	  threads.  Thanks to Ross Dargahi <rossd@acm.org> for pointing
	  this out.

	* ace/SOCK.cpp: Changed SOCK::close() to use the new
	  ACE_OS::closesocket() call.  This should fix some weird bugs
	  that have been lurking in the code for some time now!

	* ace/OS: Added a new method to ACE_OS called closesocket().  This
	  handles the differences between Win32 and UNIX in their
	  treatment of sockets (e.g., NT requires the use of
	  closesocket(), whereas UNIX requires the use of close().  Thanks
	  to Irfan, Prashant, and Tim for figuring this one out!

Sat Jun 29 21:23:04 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/SPIPE_Acceptor.cpp (create_new_instance): Added the flag
	  (FILE_FLAG_OVERLAPPED) in call to CreateNamedPipe.

Fri Jun 28 01:31:24 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Svc_Handler.cpp (open): Fixed a small typo that caused a
	  compile error if the DEBUGGING macro was enabled.  Thanks to
	  Irfan for finding this.

Wed Jun 26 03:19:27 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Synch_T.cpp (ts_get): The tss object allocated off the heap
	  should be released if setspecific fails.  Thanks to John Lu
	  <johnlu@f1.telekurs.ch> for reporting this.

	* ace/CORBA_Handler.cpp (handle_input): changed ACE_OS::send and
	  ACE_OS::recv to ACE::send and ACE::recv respectively in
	  CORBA_Handler.cpp.  Thanks to Irfan for pointing this out.
	  
        * ace/Service_Config: slightly modified the Service_Config.[h,cpp]
	  in order to make it possible to create an ACE_Service_Config
	  with an external ACE_Reactor as a parameter.  On creation I was
	  handling this partly correct (i.e., not creating a new reactor).
	  However, there was no flag for remembering this for a later
	  deletion.  Thus, on deletion I was doing a delete on the Reactor
	  regardless of who created it.  This is now fixed.  Thanks to
	  Karlheinz for pointing this out.

	* examples/ASX/CCM_App/CCM_App.cpp: Changed all uses of init (int,
	  char **) to init (int, char *[]) to work around a "feature" with
	  MSVC++ 4.x...  Thanks to Karlheinz for pointing this out.

	* ace/OS.h: Added a new typedef of TCHAR to be compatible with
	  Win32 UNICODE type names...

	* ace/{Mem_Map,DEV_Addr,SPIPE_Addr,FILE_Addr}: Added UNICODE
	  support for Win32 to all interfaces that require filenames.

	* ace/{SPIPE_Stream,SOCK_IO,FILE_IO,DEV_IO}: Added a new pair of
	  send()/recv() methods that take ACE_OVERLAPPED pointers in order
	  to make it possible to integrate seamlessly with Win32
	  overlapped I/O.  Naturally, these methods are simply
	  "callthroughs" to the ACE_OS versions...

	* ace/OS: Added a new pair of send()/recv() methods that take
	  ACE_OVERLAPPED pointers in order to make it possible to
	  integrate seamlessly with Win32 overlapped I/O.

	* ace/SPIPE_Acceptor: Factored out common code in the Win32
	  implementation of ACE SPIPES (which uses Win32 Named Pipes, of
	  course ;-)).

	* ace/SPIPE_Acceptor.h: Removed a vestige of the past --
	  ACE_SPIPE_LISTENER_H should be ACE_SPIPE_ACCEPTOR_H...

Wed Jun 19 19:35:12 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/SPIPE_{Acceptor,Connector}: Modified SPIPE_Acceptor and
	  SPIPE_Connector to implement Named Pipes on NT.  The public
	  interface remains the same.

Sun Jun 16 00:45:41 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Service_Config: Provided public accessor methods for the
	  following data memebers of the ACE_Service_Config:

		reconfig_occurred_
		end_event_loop_

	  Thanks to Steve Warwick <sjw@aesthetic.com> for suggesting this.

	* ace/Synch*: Added UNICODE support for the ACE synchronization
          classes (e.g., ACE_Mutex, ACE_RW_Mutex, ACE_Semaphore, etc.).

	* ace/OS: Added UNICODE support for the ACE_OS::dl_open()
	  function, as well as the ACE_OS synchronization functions.

	* ace/CORBA_Handler: Added Seth's changes for Orbix 2.0.

Sat Jun  1 13:30:55 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Memory_Pool.cpp (remap): Fixed a bug in
	  ACE_MMAP_Memory_Pool::remap (). The test for whether or not the
	  addr falls within the range had a '!' (not) missing, that is, it
	  was failing when it should be succeeding and vice versa.

Sun Jun  9 00:01:44 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Released version 4.0.24 for testing.

	* ace: Changed all uses of ACE_Guard<LOCK> m (lock_) to ACE_GUARD
	  (LOCK, lock_), which is a macro that is defined as follows:

          ACE_Guard<MUTEX> ace_mon (LOCK); \
	    if (m.locked () == 0) return;

	  The reason we need this is (1) detect locking failures, rather
	  than have things fail silently and (2) to automatically detect
	  deadlock in the Reactor.  In addition, I also added
	  ACE_GUARD_RETURN, which is similar to ACE_GUARD, except that it
	  returns a "failure" status when the lock is not acquired.
	  Thanks to Karlheinz for suggesting this.

	* ace/Log_Msg: Added the new thr_state() accessors to Log_Msg.

	* ace/Thread_Manager.cpp: factored out some common code by having
	  the public interfaces (like resume() and suspend()) utilize the
	  protected interfaces (like resume_thr() and suspend_thr()).

	* ace/Thread_Manager.cpp: Added sanity checks for suspend(),
	  resume(), cancel(), etc. so that we don't blow up if someone
	  tries to perform an operation on an invalid thread id.

	* ace/Thread_Manager: Added a suite of new methods for
	  (1) cooperatively "canceling" threads and (2) testing if threads
	  are cancelled (also added similar checks to test if threads are
	  suspended or resumed).  The cooperative cancellation mechanism
	  is based on a design fleshed out with Detlef and Karlheinz.
	  It's essentially a compromise between the powerful mechanisms
	  available via POSIX pthreads vs. the totally lame mechanisms
	  available in Win32.

	  Here's how it all works:

	  1. Added several new methods to ACE_Thread_Manager:

	     cancel(thr_id);     -- cancels thr_id
	     cancel_all();       -- cancels all the threads in a Thread_Manager
	     cancel_grp(grp_id); -- cancels a group of threads in a Thread_Manager
	     testcancel(thr_id); -- returns "true" if thr_id has been cancelled

	  2. Updated ACE_Log_Msg to maintain the current state of a thread
	     in thread-specific-storage (TSS).  Actually, it's more clever
	     than that since I really keep a *pointer* to the state of a
	     thread in TSS.  This pointer actually points *back* to the
	     ACE_Thread_State field in the ACE_Thread_Manager!  I use it
	     as a cache as follows:

	     ACE_Thread_Manager::testcancel (thread_t t_id)
	     {
	       ACE_MT (ACE_Thread_Mutex_Guard m (this->lock_));

	       // Try to get the cached value out of TSS to avoid lookup. 
	       ACE_Thread_State *thr_state = ACE_LOG_MSG->thr_state (); 

	       if (thr_state == 0) 
	       { // We need to init the cache.
		 int i = this->find (t_id); 
		 if (i == -1) return -1; 
		 // Update the TSS cache. 
		 ACE_LOG_MSG->thr_state (thr_state = &this->thr_table_[i].thr_state_); 
	       } 
	       return *thr_state == ACE_THR_CANCELLED;
	     }

             Note that this allows me to avoid searching the
	     Thread_Manager on every Thread_Manager::cancel() access
	     except the first one!

	  3. I've updated the examples/Threads/test_thread_manager.cpp
	     test file to exercise the new cooperative thread cancellation
	     scheme.  It basically spawns a bunch of threads that go into
	     their own event loops doing

	     if (thr_mgr ()->testcancel (ACE_Thread::self ()) != 0)
	       break;

	     every so often.  Naturally, the main thread cancels them by saying
   
             thr_mgr ()->cancel_grp (grp_id);

	     when it wants to inform them to shut down.

	* ace/Thread_Manager: Moved the Thread_State enum from the
	  ACE_Thread_Descriptor class to OS.h and renamed it to be
	  ACE_Thread_State.  This will make it easier to integrate the
	  state of a thread in thread-specific storage...

Sat Jun  8 13:35:17 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.i (sema_post): revised the implementation of the POSIX
	  Pthreads semaphore implementation just a bit in order to make it
	  slightly more efficient (it now releases the mutex before
	  signaling the condition variable).

	* ace/OS.i and config-aix.4.1.h: added a fix that separates the
	  decision about whether optlen is a pointer from the decision of
	  the type of optlen.  This fixes a problem on AIX.  Thanks to Bob
	  Olson <olson@mcs.anl.gov> for this fix.

	* ace/Proactor.h: Fixed a small glitch that was causing some
	  compilers to break due to the fact that they can't grok fully
	  qualified destructor syntax in the class definition.  Thanks to
	  Alfred Keller <kellera@pop.eunet.ch> for reporting this.

	* ace/OS.h: Added some Win32 macros (e.g., GENERIC_READ) to the
	  UNIX side of the house in order to compile the Proactor on Win32
	  and UNIX.

Fri Jun  7 19:36:27 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Added a new Bourne shell script called ACE-install.sh that will
	  automatically download and install on UNIX machines.  Thanks to
	  Ajit Sagar <asagar@spdmail.spd.dsccc.com> for contributing this.

Thu Jun  6 00:37:02 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Released version 4.0.23 for testing.

	* ace/Local_Tokens: Updated the *.cpp and *.i files to remove
	  warnings and generally improve the conformance to the ACE coding
	  guidelines.

	* examples: Moved the Proactor directory into the Reactor
	  directory since the Proactor and Reactor are really two
	  implementations of the same basic pattern.

	* ace/Memory_Pool.cpp: Fixed an inconsistency caused by not
	  updating __INLINE__ to __ACE_INLINE__.  Thanks to Neil Cohen for
	  finding this.

        * ace: Added support for the Florida State PTHREADS package.
	  Thanks to Gary Salsbery <gsalsber@simsun.atsc.allied.com> and
	  Eric Beser <beser@simsun.atsc.allied.com> for helping with this.

        * ace: Added support for the m88k OS.  Thanks to Gary Salsbery
	  <gsalsber@simsun.atsc.allied.com> and Eric Beser
	  <beser@simsun.atsc.allied.com> for helping with this.

	* ace/OS.h: Added a default value of NULL to the sigwait() OS
	  wrapper method to simplify the usecase in certain cases.

	* ace/Memory_Pool.cpp (commit_backing_store): Fixed what is
	  hopefully the last typo related to the ACE_DEFAULT_BASE_ADDR
	  macro.  Thanks to Neil B. Cohen <nbc@metsci.com> for reporting
	  this.

Thu Jun  6 15:31:40 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* ace/CORBA_Handler.h: This version of the CORBA_Handler works
	  with Orbix 2.0.  Most of the changes involve the use of C++
	  Exception Handling (the removal of IT_X), and the location of
	  some CORBA system exception classes.

	* ace/Event_Handler.h: Added handle_*_complete methods for the
	  Proactor.  The Proactor now takes Event_Handlers and calls back
	  the **_complete methods when overlapped I/O operations have
	  completed.

	* ace/Service_Config.h: Added static accessors for the Proactor to
	  the Service_Config object.  Similar to the Reactor accessors,
	  applications can now use the Service_Config object as the global
	  access point to the Proactor event demultiplexor.

Wed Jun  5 22:40:28 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.i (t_free): Added a check to avoid deleting a NULL ptr.
	  This was causing problems for the TLI_Acceptor.  Thanks to Ajit
	  Sagar <asagar@spdmail.spd.dsccc.com> for reporting this.

	* ace/Makefile: Changed things back so that both static and
	  dynamic libs are built by default...  Thanks to Brad Brown
	  <bbrown@rdxsunhost.aud.alcatel.com> for pointing this out...

Sat Jun  1 13:49:51 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Released version 4.0.22 for testing.

	* Added Tim Harrison's latest tests for Proactor.

Sat Jun  1 13:30:55 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Memory_Pool.cpp (remap): Fixed a bug in
	  ACE_MMAP_Memory_Pool::remap (). The test for whether or not the
	  addr falls within the range had a '!' (not) missing, that is, it
	  was failing when it should be succeeding and vice versa.

Fri May 31 16:31:13 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Rereleased version 4.0.21 for testing.

	* Copied over new versions of the Proactor -- there was a small
	  problem with the UNIX version that caused it not to compile...

Fri May 31 00:03:41 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* examples/Proactor/test_proactor.cpp: Added a test program for
	  the Proactor.  Check examples/Proactor/README for more details
	  on this test example.

	* ace/Proactor.cpp: Added first pass at the Proactor for win32.
	  The Proactor is a Reactor-like abstraction that uses
	  asynchronous I/O, rather than synchronous I/O.  On Windows NT we
	  implement the Proactor using overlapped I/O.  We'll soon be
	  porting the Proactor to Solaris using POSIX 4.x aio_* API for
	  real-time programming.

	  Unfortunately, the Proactor has not yet been integrated with
	  Windows NT WaitForMultipleObjects since it appears that I/O
	  Completion ports are not "waitable" objects on Windows NT.  Does
	  anyone know if this has been fixed in release 4.0?

Thu May 30 05:51:23 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Synch.i: Reordered the definitions of several methods in
	  Synch.i to avoid warnings from G++.  Thanks to Marco Sommerau
	  <sommerau@matisse.informatik.uni-stuttgart.de> for noticing
	  this.

        * ace/Log_Msg.cpp: There was a problem having to do with the order
	  in which static objects by G++.  In particular, G++ was calling
	  the constructor of the lock_ mutex in Log_Msg.cpp *after* it was
	  being used for the first time.  The right solution is to make
	  lock_ be a pointer and allocate it once in the instance()
	  method.  Thanks to Marco Sommerau
	  <sommerau@matisse.informatik.uni-stuttgart.de> for finding this
	  problem.

	* ace/TLI_Acceptor.cpp (close): Make sure to only close down the
	  TLI_Request_Queue if queue_ is non-NULL!  Thanks to Ajit Sagar
	  <asagar@spdmail.spd.dsccc.com> for spotting this.

	* ace: Changed all the enums in the various SysV wrappers from
	  things like CREATE and OPEN to ACE_CREATE and ACE_OPEN to avoid
	  name clashes with other systems.  In addition, also changed
	  NONBLOCK to ACE_NOWAIT to avoid clashes with the existing
	  ACE_NONBLOCK macro!  Thanks to Steve Warwick <sjw@aesthetic.com>
	  for suggesting this.

	* ChangeLog: Changed all usages of the INLINE macro to ACE_INLINE.
	  This avoids name clashes with other systems.  Thanks to 
	  Chris Eich <Chris_Eich@optilink.optilink.dsccc.com> for
	  suggesting this.

Mon May 27 13:03:58 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Map_Manager.cpp (trybind): The function trybind() doesn't
	  return a value as it should.  A return was missing from the last
	  line of the function.  Thanks to Stuart Powell
	  <stuartp@in.ot.com.au> for finding this problem.

	* ace/Acceptor.cpp (dump): The debug print referred to
	  "scheduling_strategy_" which doesn't exist in the relevant
	  class.  Replacing it with "concurrency_strategy_" fixes the
	  problem.  Thanks to Stuart Powell <stuartp@in.ot.com.au> for
	  finding this problem.

	* ace/Mem_Map.i: Make sure to close down the file mapping
	  correctly when we upmap the view!

	* ace/OS.h: Changed the default shared memory address from 16 M to
	  64 M in order to work around problems with AIX.

	* ace/Memory_Pool: Moved and renamed the enums in
	  ACE_Shared_Memory_Pool so that they'd be in OS.h.  This makes it
	  easier to remember to change them if they are incorrect.  Thanks
	  to Lionel Mommeja <mommeja@vnet.ibm.com> for suggesting this.

	* ace/Stream.cpp: Removed #if defined (ACE_HAS_THREADS)

	* ace/OS.cpp (svc_run): Added a Win32 try/except block to
	  Spawn_Args::svc_run so that we catch all Win32 structured
	  exceptions in order to make sure that we clean up correctly when
	  the thread exits.

Sun May 26 11:37:08 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Local_Name_Space.cpp: Used the new Win32 exception
	  integration in order to ensure that the Name Server will
	  transparently work correctly when the backing store is extended
	  by other processes on the same machine.

	* ace/Memory_Pool.cpp: Revised the ACE_MMAP_Memory_Pool to export
	  the mechanism for extending the virtual memory mapping.  This
	  can now be called by other programs (e.g., in order to integrate
	  with Win32 Structure Exception Handling).

	* ace/Memory_Pool.cpp: Changed the use of ACE_OS::lseek() to
	  ACE_OS::filesize() in order to determine the current offset when
	  we're remapping the address space.

Wed May 22 13:08:44 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/OS.h (ACE_DEFAULT_TIME_SERVER_STR): Added a new entry for
	  ACE_DEFAULT_TIME_SERVER_STR. 

	* ace/Malloc_T.cpp (advance): Fixed two small bugs. In
	  ACE_Malloc::try_bind(), if we have a match we need to set
	  pointer to node->pointer_ and not node->name_.
	  Ina ACE_Malloc_Iterator::advance(), the continue in the for loop
	  should be for strcmp != 0 instead of == 0.

Sun May 19 12:03:11 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Released version 4.0.20 for testing.

	* ace/Service_Record.cpp (remove): Fixed a very mysterious bug
	  that was caused by deleteing an object and then trying to access
	  it's next_ pointer.  This worked on UNIX, but fortunately the
	  MSVC++ compiler does special things to deleted memory and the
	  bug was revealed!  At long last, MSVC++ does something right
	  ;-).

	* ace/Module.cpp: Revised the code a bit to use the ACE_SET_BITS
	  and ACE_CLR_BITS macros to improve readability.

	* ace/SV_Semaphore_Complex.cpp (open): Fixed a race condition
	  where we weren't correctly checking for EIDRM.  Thanks to
	  Michael Fortinsky <mike@vocaltec.com> for reporting this.

Sat May 18 10:49:04 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace: Added a new ace.mak and ace.mdp file for Win32.

	* ace/Service_Record.cpp: Rewrote some code to work around a bug
	  with MSVC++.  This bug was causing problems since the
	  ACE_Shared_Object methods were getting called, rather than the
	  Test_Task methods used in the examples/ASX/CCM_App.cpp file.
	  Thanks to Tom Leith for pointing out this problem!

	* ace/OS.h: Added a new #define for ACE_DEFAULT_SVC_CONF to deal
	  with differences between NT and UNIX pathnames.

	* ace/Time_Value.h: Moved the definition of the INLINE macro from
	  OS.h to Time_Value.h so that it will be in scope for
	  Time_Value.i.  Thanks to Neil Cohen for reporting this.

	* examples/Reactor/Misc/signal_tester.cpp: There was a typo in
	  signal_test.cpp.  It had mean to use handle_input() rather than
	  handle_output() to exercise the asynchronous signal handling
	  capabilities.  This is fixed now.

	* apps/Synch-Benchmarks/Benchmark.cpp (thr_id): Added a new #if
	  define (ACE_HAS_DCETHREADS) to make this work on AIX.  Thanks to
	  Greg Wilson <gvw@cs.toronto.edu> for reporting this.

	* ace/Local_Name_Space: Moved ACE_NS_String and ACE_NS_Internal
	  from the *.cpp file to the *.h file to work around a "feature"
	  of the AIX C++ compiler.  Thanks to Greg Wilson
	  <gvw@cs.toronto.edu> for reporting this.

	* ace/Reactor.h (ACE_Handler_Repository): Changed the type of
	  cur_size_ from size_t to ssize_t to avoid type mismatches.

	* ace/Name_Request_Reply.cpp (decode): Fixed some inconsistencies
	  between signed and unsigned loop counters...

	* ace/OS.h: Changed the typedef of pid_t on Win32 from
	  DWORD to long to be consistent with UNIX.

Thu May 16 18:49:14 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Released version 4.0.19 for testing.

	* build/SunOS5.4/ace/ACE.cpp (ldfind): Fixed a bug in ldfind()
	  that caused a segfault if we didn't resolve the filename in the
	  LD_SEARCH_PATH.

	* ace/Reactor and Timer_Queue: Changed the interface of cancel()
	  to include a const void **arg.  If arg is non-NULL then it will
	  be set to point to the ``magic cookie'' argument passed in when
	  the Event_Handler was registered.  This makes it possible to
	  free up the memory and avoid memory leaks.

	* ace/Service_Record: Removed the #ifdefs that checked if
	  ACE_HAS_THREADS because we ought to be able to build all of this
	  stuff now that we've got the ACE_OS wrappers.

	* ace/Svc_Conf.y: Removed the #ifdefs that checked if
	  ACE_HAS_THREADS because we ought to be able to build all of this
	  stuff now that we've got the ACE_OS wrappers.

	* ace/OS.h (ACE_DEFAULT_BACKING_STORE): Made a different
	  ACE_DEFAULT_BACKING_STORE for NT and for UNIX to handle the
	  differences in directory separator characters...

Wed May 15 18:45:48 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* examples/ASX/CCM_App/CCM_App.cpp: Fixed up the test application
	  so that it should support dynamic linking on Win32.  Thanks to
	  Tom Leith for reporting this.

	* ace: Added the ACE_Export macro to class ACE and the various
	  "helper" classes related to ACE_Malloc in order to have this
	  work properly when use with ACE_Malloc outside of the ACE DLL.

	* ace/Svc_Conf.l: Added support for '\' and ':' in the regular
	  expression for an ACE pathname in order to support Win32
	  filenames (e.g., "C:\foobar\").  Thanks to Tom Leith
	  <trl@icon-stl.net> for reporting this.

	* ace/Malloc_T.cpp (ACE_Allocator_Adapter): Moved the constructor
	  from the *.i file to the *.cpp file and added a new constructor
	  that takes both a pool_name *and* a lock_name.  This is
	  necessary because the ACE Malloc now has this API, as well.

	* examples/Threads/test_barrier.cpp (main): Fixed a bug that was
	  caused by the main() thread exiting before all the other worker
	  threads had finished "waiting" on their Barrier.  The fix is to
	  use ACE_Thread_Manager to control the thread exits...

Mon May 13 00:03:09 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* examples/Connection/non_blocking/CPP-acceptor.cpp: Modified the
	  implementation of the Svc_Handler::open() method so that it will
	  truly behave as an iterative server (as advertised...).
	  Currently, it behaves as a half-iterative server (i.e., the
	  Oneshot_Acceptor is iterative, but the Svc_Handler is
	  "concurrently"), which is causing problems because we're wiping
	  out the values of Svc_Handler each time through the main event
	  loop.  Thanks to Gerolf Wendland for noticing this problem.

	* ace/Log_Msg: Added an alternative logging mechanism that makes
	  it possible to integrate variable argument lists from other
	  logging mechanisms into the ACE mechanism.  Thanks to Chris
	  Lahey for proposing this.

	* ace/Synch.h: Moved ACE_Process_Mutex so that it appears *after*
	  ACE_Mutex (since it depends on ACE_Mutex).  Thanks to Dieter
	  Quehl for finding this.

	* Released version 4.0.18 for testing.

	* ace/Name_Space.cpp: Added the ACE_BUILD_DLL macro at the
	  beginning of this file so that it will build as a DLL on NT
	  correctly.

	* ace/Name_Space.cpp: Added a default constructor for
	  ACE_Name_Binding so that it will compile when used as a template
	  argument for ACE_Unbounded_Set.

Sun May 12 14:23:44 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Map_Manager: Totally reworked the Map Manager so that it can
	  be more flexible with respect to where the allocator comes from.
	  This is necessary for certain parts of ACE (e.g.,
	  Local_Name_Space) that must be very careful about which
	  allocator is used to manage memory.

	* ace/Synch: Moved ACE_Process_Mutex and ACE_RW_Process_Mutex
	  *outside* of the ACE_HAS_THREADS #ifdef since these are now
	  always defined on all platforms (because the Process_Mutex stuff
	  uses SV Semaphores, which are portable even if we don't have
	  threads!).

	* ace/Naming_Context.cpp (parse_args): Removed an unnecessary call
	  to strdup().  This was detected by Purify!

Sun May 12 14:26:20 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Local_Name_Space.cpp (shared_bind): Fixed a small bug. In
	  computing type_len in shared_bind(), we needed to add 1 to
	  account for the NUL character.

	* ace/Local_Name_Space.cpp: (list_types): Fixed some potential
	  memory leaks. In list_types() as well as list_type_entries()
	  calling pattern.char_rep() was allocating memory which was never
	  getting deleted. Similarly, in list_names() and list_values,
	  call to char_rep was also allocating memory that was not getting
	  deleted.

Sat May 11 16:19:51 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Log_Msg.cpp (local_host): added a static member to
	  ACE_Log_Msg that maintains the local host name.  Now, instead of
	  always displaying "<local host>", we can insert the actual local
	  name into the object and then it will be automatically printed
	  when VERBOSE mode is enabled.  Thanks to Chris Lahey for
	  suggesting this.

	* ace/Local_Name_Space.cpp: Used the new ACE_Name_Binding class to
	  simplify the implementation of all the list_* methods in
	  ACE_Local_Name_Space.

	* ace/Name_Space.cpp: Made a number of changes to the
	  ACE_Name_Binding class in order to make it work more efficiently
	  and concisely (e.g., reduce the amount of copying and eliminate
	  the need for converting the type field back and forth to/from
	  ACE_WStrings).

	* examples/Service_Configurator/IPC-tests/server/Handle_L_Dgram.cpp:
	  Fixed a typo where #if !defined (ACE_LACKS_UNIX_DOMAIN_SOCKETS)
	  was *before* the #include of the header file that defines this
	  macro!  Thanks to Nigel for pointing this out, as well.

	* ace: Added a number of fixes to make ACE compile on SCO UNIX
	  3.2.4 using gcc 2.7.2.  Thanks to Nigel Lowe <nigel@nt.com> for
	  helping with this.

	* netsvcs/lib/Name_Handler.cpp: operation_ needs to be declared as
	  just LIST_OP and not ACE_Name_Handler::LIST_OP. For some strange
	  reason NT complains otherwise.  Thanks to Prashant for finding
	  this.

Fri May 10 01:09:17 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * ace: Added new versions of ace.mak and ace.mdp to fix a couple
	  of minor typos.

	* ace/Malloc_T.cpp (ACE_Malloc): Added a new constructor that
	  takes both the pool_name and the lock_name explicitly.  This is
	  more flexible.  Thanks to Ramesh Nagabushnam <rcn@nynexst.com>
	  for suggesting this.

	* ace/Malloc_T: Modified the constructor of ACE_Malloc so that by
	  default the name of the memory pool (which is also used as the
	  name of the lock...) is ACE_DEFAULT_MUTEX.  

	* Released version 4.0.17 for testing.

	* ace/Connector.cpp (create_AST): Must reset errno = EWOULDBLOCK
	  to avoid making caller's think that something else has gone
	  awry...  Thanks to Steve Warwick <sjw@aesthetic.com> for chasing
	  this down!

	* ace/ACE.cpp (handle_timed_complete): If you issue a non-blocking
	  connect on a socket, you will have back a failure with errno =
	  EINPROGRESS.  Then, if for some reason, the connection could not
	  be established, the select (which you have to issue to know
	  about the completion of connection) will return you the fd set
	  both in the read mask and in the write mask (infact select
	  returns 2 in this case).  The behaviour above affects the method
	  ACE::handle_time_complete, so I changed the last part of the
	  above method, this way:

	  if (n <= 0)
	  {
	  ...
	  ...
	  }
	  else if (rd_handles.is_set(h))
	  {
	    char dummy;
	    // The following recv() won't block provided that the
	    // ACE_NONBLOCK flag has not been turned off .

	    if (ACE::recv (h, &dummy, 1, MSG_PEEK) <= 0)
	      return ACE_INVALID_HANDLE;
	  }

	  // 1. The HANDLE is ready for writing or 2. recv() returned that
	  // there are data to be read thus the connection was successfully
	  // established.
	  return h;   

	  That is, I reversed the sense of the tests so that the
	  rd_handles() is checked first for failure along with the recv().
	  Thanks to Antonio Tortorici <antonio@rh0011.roma.tlsoft.it> for
	  suggesting this.

	* examples/Threads/test_thread_manager.cpp (main): Changed argv[1]
	  to argv[2].  Thanks to Andres Kruse <kruse@cern.ch> for finding
	  this problem.

	* examples/Connection/non-blocking: Fixed some nasty bugs that
	  caused the non-blocking connector and acceptor test programs to
	  crash and burn.  Thanks to Steve Warwick and Gerolf Wendland for
	  finding this problem.

	* ace/SV_Semaphore_Simple.cpp (open): Check for
	  ACE_INVALID_SEM_KEY and return -1 in this case.

	* ace/Synch.h: Removed the default value of 0 for the name of the
	  ACE_Process_Mutex and the ACE_RW_Process_Mutex and replaced it
	  with a new macro called ACE_DEFAULT_MUTEX.  Using 0 didn't make
	  any sense on either NT or UNIX because process-wide Mutexes
	  should be named!

	* ace/SV_Semaphore_Simple.cpp (name_2_key): Added a check for name
	  == 0 and bail out of that's the case rather than crash!

	* ace/Reactor.cpp (wait_for_multiple_events): In the Reactor's
	  wait_for_multiple_events method, the do {} while () around the
	  select/poll system call is trying to wait until some "good"
	  event occurs, with handle_error() taking care of unexpected
	  problems.  In the case of a bad file descriptor, however,
	  handle_error() returns 0.  This was exiting the loop because the
	  loop exit condition was:

	  do { /* ... */ } while (nfound == -1 && this->handle_error () > 0);

	  which eventually causes ACE_Service_Config::run_event_loop() to
	  exit.  Since the offending file descriptor is handled by
	  handle_error(), the loop should continue.  Therefore, I've
	  changed the while to read:

	  while (nfound == -1 && this->handle_error () >= 0);

	  Thanks to Eric C. Newton <ecn@clark.net> for providing this fix.

	* ace/INET_Addr.cpp (string_to_addr): Changed the order of the
	  parameters so that the form is now "ip-address:port".  This
	  should (finally) be consistent for both string_to_addr() and
	  addr_to_string()...

	* ace/Log_Msg: Changed the char * parameter of the log() method to
	  const char *.  Thanks to Chris for suggesting this!

	* ace/Synch_T.cpp: Moved the #if defined (ACE_HAS_THREADS) down to
	  the right part of the file...  Thanks to Alex Karev
	  <akg@na47sun05.cern.ch> for finding this.

	* ace/Malloc.h: Added a very important #else...  Thanks to Alex
	  Karev <akg@na47sun05.cern.ch> for finding this.

	* ace/Signal.i (ACE_Sig_Guard): Changed the sense of the #ifdef
	  tests in the ACE_Sig_Guard constructor and destructor from #if
	  !defined (ACE_MT_SAFE) to #if 0 // !defined (ACE_MT_SAFE) in
	  order to get the right semantics for signals (which should be
	  blocked "process wide").

	* ace/Synch_T.h: put the frigging copy constructor in the public
	  section of ACE_Atomic_Op because it was causing trouble for
	  NT...

Mon May  6 00:11:37 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Released version 4.0.16 for testing.

	* ace/Log_Msg.cpp: Was defining ACE_Recursive_Thread_Mutex in the
	  wrong place (i.e., outside of the #if defined (ACE_MT_SAFE).
	  This was screwing up HP/UX.  Thanks to Neil Cohen for pointing
	  this out!

	* Incorported new versions of ace.mdp and ace.mak for Win32.

Sun May  5 16:18:43 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* netsvcs/lib/Server_Logging_Handler.cpp (handle_input): Fixed a
	  bug whereby handle_input() was returning the number of bytes
	  read by handle_logging_record() rather than 0 or -1.  This was
	  causing problems for the logger since it was hanging in read()!

	* ace/Synch_T.cpp: Fixed some minor problems with the use of const
	  in ACE_Atomic_Op that was causing warnings.

Sat May  4 16:31:46 1996  Douglas C. Schmidt  (schmidt@mambo.cs.wustl.edu)

	* ace/SOCK_Dgram_Bcast: Reimplemented most of the ACE socket
	  broadcast mechanism to (1) clean up the code and have it use
	  other parts of ACE and (2) make it work for Windows NT.  Thanks
	  to Steve Weismuller <spweismu@rsoc.rockwell.com> for the basic
	  ideas here.

	* ace/INET_Addr: Added a new method to set the port number without
	  changing the host address.  This is useful in the broadcast
	  class.

	* ace/Log_Record.cpp (print): Changed the hack of replacing the
	  newline with a call to flush() instead.  This seems like a
	  better fix.  Thanks to Alex for suggesting it.

	* ace/Log_Msg.cpp (log): Moved the order of the print operations
	  so that the ostream one goes last.  This avoids a nasty problem
	  due to the fact that it replaces the newline (if any).  Thanks
	  to Alex for pointing this out too!

	* ace/Log_Msg.cpp (log): Don't auto-increment bp at the end of
	  the log() method, instead just terminate it:

	  *bp = '\0';			// Terminate bp. 

	  This makes the length computation correct...  Thanks to the
	  ever-vigilent Alexandre Karev <akg@na47sun05.cern.ch> for
	  reporting this.

	* examples/Shared_Malloc/test_malloc.cpp: Fixed a bug where a void
	  * that was really an int was being cast incorrectly.  Thanks to
	  Raj for pointing this out.

Sat May  4 12:51:25 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Reactor.cpp (find): Modified the ACE_Handler_Repository so
	  that it doesn't crash when it isn't initialized properly.
	  Thanks to Darrin for pointing this out.

	* ace/Synch_T.cpp (wait): Changed the call wait(ACE_Time_Value *)
	  to wait(const ACE_Time_Value *) since wait() will not change the
	  time value object.

	* ace/Thread_Manager.cpp (wait): Changed the call
	  wait(ACE_Time_Value *) to wait(const ACE_Time_Value *) since
	  wait() will not change the time value object.  Thanks to Chris
	  Lahey for suggesting this.

	* ace/Synch.h: Added a (const char * = 0) argument to
	  ACE_Null_Mutex so that it would work correctly with
	  ACE_Thread_Mutex and ACE_Process_Mutex...

Fri May  3 17:26:07 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

        * netsvcs/lib/Name_Handler.cpp (lists_entries): Used '_' with
          name/value/type in ACE_Name_Binding to be consistent with the
          notation. 

Fri May  3 02:24:19 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Synch: Updated ACE_Process_Mutex to use SV_Semaphore_Complex
	  as the UNIX implementation.  This seems like the only portable
	  and robust way to get the same semantics on UNIX and on NT!

        * ace/Malloc_T: It turned out there was a subtle bug with
	  ACE_Malloc on NT when used with the ACE_Process_Mutex
	  concurrency policy.  On NT, we were storing the *HANDLE* of a
	  mutex in shared memory.  Naturally, this didn't make any sense
	  since each HANDLE is relative to only one process!!! (duh ;-)).
	  This worked fine on UNIX because mutex_t's created with
	  USYNC_PROC mode can be stored in shared memory and accessed
	  directly...

	  We fixed this by changing ACE_Malloc so that the 
	  LOCK is allocated in non-shared memory.  We then
	  fixed ACE_Process_Mutex so that on UNIX it is
	  implemented with SV_Semaphore_Complex.  This is
	  (a) portable and (b) it gives the right semantics.
	   
	  As a result, we were able to totally eliminate the storage of
	  the lock in shared memory.  Therefore, it doesn't matter of the
	  host crashes anymore!  In addition, we were able to totally
	  remove the ugly "init_finished" lock that was previously stored
	  in shared memory by ACE_MMAP_Memory_Pool.  This is *much*
	  cleaner!!
	   
	  Thanks to Karlheinz et al for pointing this problem out in the
	  first place!

	* ace: Removed a stray file called Svc_Conf_tokens.h.  This was
	  causing problems on Win32 due to name clashes...  Thanks to Adam
	  Miller <adam@royalblueny.com> for pointing this out.

	* ace/SString.cpp (strstr): there were some for (size_t j; ...) {}
	  if (j == x) constructs in the code that have as of recently
	  become non-standard.  Thanks to Darrin <darrin@jeeves.net>
	  for reporting this.

Tue Apr 30 00:18:46 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Thread.i (self): Commented out the ACE_Trace call in the
	  ACE_Thread::self() methods to avoid infinite recursion problems
	  on Win32.

	* ace/Token.cpp (ACE_Token): Commented out the ACE_Trace call in
	  the constructor of ACE_Token to avoid infinite recursion
	  problems on Win32.

	* ace/Log_Msg.cpp (instance): Moved the definition of the static
	  variable keylock_ into the static instance() method in order to
	  avoid "order of initialization" problems on Win32.  Thanks
	  to Tim for figuring this out!

Sun Apr 28 17:07:58 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* netsvcs: Rearranged and renamed the subdirectories so that they
	  are now called ./netsvcs/{lib,clients,servers}.  In addition,
	  moved the Logger, Naming, and Tokens examples from ./examples
	  into the ./netsvcs/clients directory in order to make the
	  relationships more clear.

Sat Apr 27 14:23:43 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Name_Space.cpp (operator ==): Created a new file
	  Name_Space.cpp and moved the definitions for
	  ACE_Name_Binding::operator== and ~ACE_Name_Space in it. Also
	  modified code to use '_' at the end of name/value/type in
	  ACE_Name_Binding.

Sat Apr 27 16:00:03 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/INET_Addr.i (get_host_addr): There was an error where
	  sprintf(s,"%d:%s" ...) should have been %s:%d.  Thanks to
	  Raj <raj@itd.ssb.com> for pointing this out.

Mon Apr 22 01:24:45 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Dump_T.h: #included "ace/Dump.h" so that this file will
	  compile on HP/UX.  Thanks to Neil Cohen for reporting this
	  problem.

        * Released version 4.0.15 for testing.

	* ace/Synch_T: Added the appropriate "const" qualifiers to certain
	  operators in ACE_Atomic_Op.

Sun Apr 21 12:54:18 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace: Fixed a problem that Dieter was having with the Name Server
          when toggling between Naming_Contexts.  Basically, what I've
          done is

	  1. Moved the unmap() call into the ACE_Mem_Map::close() method
	     (this ensures that the region is correctly unmapped when the
	     Mem_Map is deleted).

	  2. I've removed the call to this->allocator_->remove () within
	     ~ACE_Local_Name_Space.  This ensures that we don't remove the
	     backing store file.

	* ace/Mem_Map.cpp: Modified the ACE_Mem_Map::remove method to call
	  ACE_Mem_Map::close() in order to share code.

	* ace/Mem_Map.cpp: Modified the ACE_Mem_Map::close() method so
	  that it unmaps the mapped region before closing down the backing
	  store.  This prevents "dangling mapping."

	* ace/Local_Name_Space.cpp (ACE_Local_Name_Space): Initialized all
	  the pointers to NULL.

	* ace/Synch_T.cpp (ACE_Atomic_Op): Enhanced the Atomic_Op
	  implementation by adding an assignment operator and disallowing
	  the copy constructor (forcing objects of ACE_Atomic_Op to be
	  passed by reference).

	* examples/Naming/Client/Client_Test: Reorganized the code for
	  Client_Test so that it will run correctly as a Win32 netsvc
	  (e.g., added the ACE_Svc_Export macro).

Sun Apr 21 20:23:40 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Naming_Context.cpp (close): Added a new method to
	  Naming_Context called close() that deletes the instance of
	  name_space_.

	* ace/Local_Name_Space.cpp (ACE_Local_Name_Space): Added stuff to
	  the destructor of Local_Name_Space so that it calls remove on
	  the allocator_ to ensure we unmap the file. Also, we delete the
	  allocator_.
	 
	* examples/Naming/Client/Client_Test.cpp (set_proc_local): Changed
	  set_proc_local (), set_node_local() and set_host() so that
	  before we change name space, we do a close() on
	  Naming_Context. The close ensures that we unmap the file as well
	  as delete the instance of the name space.
	
Sat Apr 20 12:39:20 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace: Removed the Name_Options.* files and merged the
	  ACE_Name_Options class into Naming_Context.*.  This simplifies
	  some order of include problems...

	* ace/Naming_Context.cpp (init): Switched the code so that rather
	  than always opening with ACE_Naming_Context::PROC_LOCAL, we use
	  ACE_Name_Options::context(), which can be overridden by using
	  the new -c command-line option (e.g., -c NODE_LOCAL).  Thanks to
	  Dieter for suggesting this.

	* ace/OS.i: Modified the Win32 implementation of all the
	  ACE_OS::flock_*lock() methods so that they'd have the same
	  behavior as the UNIX ones with respect to a length of 0 meaning
	  "lock the entire length of the file."  This works, of course, by
	  having each method check if len == 0, and if so, calling
	  GetFileSize() to set the size of the file.

	* ace/Synch.h: Changed the default len value for all the
	  File_Lock::*acquire* methods to 1 rather than 0 to work around a
	  problem with Win32.  Thanks to Detlef for reporting this.

	* ace/ACE.cpp (ldfind): Added a strdup() of the LD_SEARCH_PATH
	  returned by getenv() so that we don't overwrite the environment
	  variable by using strtok().  Thanks very much to Prashant for
	  figuring this out!

Thu Apr 18 22:13:43 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* examples/Naming/Client/Client_Test.cpp (list_value_entries):
	  Added check in list_name_entries and list_value_entries to see
	  if type actually exists before trying to print it out.

Wed Apr 17 16:40:42 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * Released version 4.0.14 for testing.

        * Added Tim Harrison's new instructions for building and using ACE
	  as a DLL and SLL on Win32.

	* ace/Svc_Conf.h: Due to the new changes to the yacc code, I had
	  to move the definition of YYSTYPE into the Svc_Conf.h file
	  rather than have it in the Svc_Conf.y file.  This solves a
	  variety of multiple-inclusion problems...

	* ace: Modified all the yacc token symbols so that they will be
	  prefixed with ACE_.  This avoids namespace pollution problems.

	* Added the ACE_STATIC_SVC* macro support to a number of files so
	  that the static versions of all the ACE services will be
	  registered with the ACE Service Repository correctly.  Thanks to
	  Jesper for pointing this out!

	* ace/OS.h: the first occurence of 

	  typedef thread_t tid_t;

	  in the OS.h file should read

	  typedef pthread_t tid_t;

	  Thanks to Jan Rychter <jwr@icm.edu.pl> for reporting this.

	* ace/Read_Buffer.cpp: Fixed rec_read() so that it will fail
	  correctly when new fails!

Wed Apr 17 19:05:42 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* netsvcs/lib/Name_Handler.cpp (type_request): Here is a brief
	  description of the changes made to ACE_Name_Handler to simplify
	  the dispatch method and make it more elegant:

	  1) I created a table called op_table_. It contains pointers to
	     member functions of ACE_Name_Handler. This table can be
	     indexed using the msg_type. However, I went one step further
	     to have all the list methods be grouped under two
	     methods. That is, requests for list_names, list_values, and
	     list_types are handled by one method called lists() and
	     similarly, requests for list_name_entries,
	     list_value_entries, and list_type_entries are handled by
	     another method called lists_entries(). A MASK is used to have
	     the op_table_ index to the same method for these requests.

	  2) I also created another table called list_table_. This is
	     primarily used by lists() to keep track of a couple of things:
	           + pointers to member functions of Name_Handler that
		     handle the actual request.
		   + pointers to member functions of Name_Handler that act 
		     as factories to create the appropriate request to
		     send back. 
		   + description of the message type.
		   
	     A different MASK is used to index into the list_table_ to
	     invoke the appropriate method or get the appropriate description.

	 3) Within the method lists_entries(), I once again make use of
	    the pointers to member functions technique. This time,
	    however, I use pointers to member functions of Naming_Context
	    which I assign in the switch statement.

Tue Apr 16 13:03:49 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * Released version 4.0.13 for testing.

	* ace/INET_Addr.i: moved the get_port_number routine up to the top
	  of the file so it gets defined before it is used.  Linux did not
	  like it where it was...  Thanks to Neil Cohen for reporting
	  this.

	* ace: Split the Dump.* files into Dump_T.* files.  This is
	  necessary to support the template policies of various C++
	  compilers.

	* ace/Malloc_T.cpp (dump): Fixed an erroneous use of -> since
	  guard_ is a non-pointer...  Thanks to Neil Cohen for reporting
	  this.

	* ace/Log_Record.cpp (print): Finally figured out how to do
	  extensible ostream logging so that it will seamlessly work with
	  ACE_Log_Msg.  This required one change to ACE_Log_Record,
	  however.  In Log_Record.cpp:

	  In ACE_Log_Record::print(char *, int, ostream, size_t len), added 

	  char *t = this->msg_data_[len - 1];

	  if (t == '\n')
	    *t = '\0';

	  s << this->msg_data_ << endl;

	  This is required because the virtual function overflow() in
	  streambuf does not get called until endl is called to flush the
	  buffer.  Note that (at least on AIX), '\n' is treated separately
	  from endl and will not cause the overflow() function to be
	  called.  Thanks to Chris Lahey for this idea.

	* ace/OS: Added a new wrapper for strrchr().

	* ace/Token_Collection.cpp (renew): Added a cast of
	  (const char *) to token_name so that the conversion operator
	  will get called correctly.  Thanks to Gonzalo Diethelm
          <gonzo@ing.puc.cl> for reporting this.

Tue Apr 16 13:29:32 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Name_Request_Reply.cpp (decode): Fixed a small bug in encode()
	  and decode() of ACE_Name_Request. When doing ntohs and htons, we
	  only ought to do it for the name and value part of data. type
	  needed to be left alone since it is not a short.

Mon Apr 15 02:31:00 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* include/makeinclude/platform_hpux_orbix.GNU: Added
	  David.L.Sames.1@gsfc.nasa.gov (David Sames) config*.h file and
	  platform_*.GNU file for HP/UX 9.x using Orbix.

	* ace/OS.i: Fixed all uses of pthread_cleanup_{pop,push} so that
	  they will work correctly if (1) the OS implements the as macros
	  and (2) if these macros must obey strict nesting rules...
	  Thanks to Reginald S. Perry <perry@zso.dec.com> for pointing out
	  how to do this effectively.

	* ace/Thread_Manager.h: Fixed a typo where the typedef 
	
	  typedef (ACE_Thread_Manager::*THR_FUNC)(int, int);

	  was lacking a return value.  Thanks to Reginald S. Perry
	  <perry@zso.dec.com> for reporting this.

	* netsvcs/bin/main.cpp (main): Fixed the main program so that it
	  passes the options correctly for the statically linked service
	  invocations.  Thanks to Jesper for reporting this.

	* examples/Naming/Client/Client_Test: Updated the client test
	  program so that it will work on Window NT, where it's not valid
	  to select() on non-socket HANDLEs (ugh).  Thanks to Jesper for
	  pointing this out...

	* Released version 4.0.11 for testing.

Mon Apr 15 00:20:02 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Local_Name_Space.cpp (strstr): Fixed ACE_NS_String::strstr
	  to function properly. It was assuming that length of the pattern
	  as well as the string was in units of ACE_USHORT16 when in
	  reality the length is number of bytes.

	* ace/Local_Name_Space.cpp (value_): Modified ACE_NS_Internal so
	  that instead of taking an ACE_NS_String for type, it now take a
	  char*. It therefore keeps type around as a char*. This should
	  help solve some problems we were encountering with byte ordering
	  when sending data between NT machines and Sun.

	* netsvcs/lib/Name_Handler.cpp: Cleaned up lists_entries by making
	  use of pointer to member functions. A single call to the
	  appropriate list method takes care of everything.

Sun Apr 14 16:21:32 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/INET_Addr.i (addr_to_string): Swapped the order that the
	  hostname and port number are printed to make this consistent
	  with the way that ACE_INET_Addr::string_to_addr works.  Thanks
	  to Ashish Singhai <singhai@delirius.cs.uiuc.edu> for pointing
	  this out.

	* ace/TLI_Acceptor: Changed the methods to take an ACE_Addr rather
	  than an ACE_INET_Addr.  This allows other address families (such
	  as DECnet) to be used with the TLI wrappers.  Thanks to Ajit
	  Sagar <asagar@spdmail.spd.dsccc.com> for suggesting this.

	* ace/Local_Name_Space.cpp (list_types): Removed the use of
	  regular expression matching for the name and value types of the
	  name server and replaced these with substring matching instead.
	  This is necessary since we're working with wide characters here,
	  and it doesn't make any sense to perform regular expressions on
	  these puppies...

	* ace/Local_Name_Space.cpp: Added a new strstr() method on all the
	  ACE_NS_String class so that we can compare substrings for wide
	  character types.

	* ace/SString: Added a new strstr() method on all the
	  ACE_[WSC]String classes so that we can compare substrings, 
	  even for wide character types!

	* apps/gperf: Incorporated the GNU gperf program from the FSF.
	  We're going to make some improvements to this for a subsequent
	  paper.

Sun Apr 14 15:30:05 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Name_Request_Reply.h: Changed the enum values for the
	  Constants such as BIND, REBIND, etc. The new values allow us to
	  do bitwise operations using MASK to be able to dispatch the same
	  method for all the list operations. For use case of this, please
	  see Name_Handler::dispatch().

	* netsvcs/lib/Name_Handler.cpp (dispatch): Completely changed
	  dispatch() so that now it uses a table of pointer to member
	  functions to call the appropriate method when a request
	  arrives. In addition, requests for LIST_NAMES, LIST_VALUES, and
	  LIST_ENTRIES are now handled by one method called lists() in which
	  I factored out a lot of common code. Similarly, requests for
	  LIST_NAME_ENTRIES, LIST_VALUE_ENTRIES, and LIST_TYPE_ENTRIES are
	  handled by lists_entries(). This has really cleaned up the code.

Sat Apr 13 15:26:51 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Name_Request_Reply.cpp: Made changes so that all
	  byte-ordering computations take place in encode and decode
	  methods of ACE_Name_Request_Reply and ACE_Name_Reply
	  only. Previously some of these computations were taking place in
	  Get/Set methods such as name_len() which was highly error prone.
	  (init): Added new methods called init() to both ACE_Name_Request
	  and ACE_Name_Reply that initialize length to size of transfer_. This
	  is needed since the length gets set only once in the constructor
	  and after that each call to encode() switches the byte ordering
	  causing problems.

Sat Apr 13 11:44:16 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Released version 4.0.10 for testing.

	* ace: Removed the ACE_HAS_THREAD_T macro from various places.
	  This was unnecessary given the new scheme for dealing with
	  threading.

	* ace/config-linux-pthread.h: Fixed a typo that was preventing
	  compilation from working.  Thanks to Jan Rychter
	  <jwr@icm.edu.pl> for finding this.

Fri Apr 12 13:17:47 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* apps/Gateway/Gateway: The gateway application appears to
	  be working again!

	* ace/OS.cpp (thr_create): Based on conversations with Chris
	  Lahey, modified the pthreads ACE_OS::thr_create implementation
	  so that it doesn't try to assign the hthread_t thr_handle since
	  this is meaningless in pthreads...

	* apps/Gateway/Gateway/Gateway.cpp: Fixed a typo that was causing
	  the system to go into an infinite loop when the config file was
	  empty!

	* apps/Gateway/Gateway/Gateway.cpp: I was forgetting to set the
	  line_number to 0 before calling read_entry()...

	* ace/Parse_Node.cpp: Fixed a dumb error that arose because I
	  forgot that you can't call dlerror() twice and get the same
	  result (it returns NULL the second time).  As usual, RTFM.

        * ace: Removed ACE_HAS_TLI from all the SunOS 4.x config*.h files
	  and platform_*.GNU files.  There are just too many bugs with TLI
	  on SunOS 4.x to support it by default...

        * examples: Made some minor fixes to make the examples all compile
	  with GCC.

	* apps/Gateway/Gateway/Gateway: Reimplemented the Gateway
	  application as to be an ACE network service.  This should make
	  life much easier on platforms with broken C++ templates...

	* apps/Gateway/Gateway: Revised the Config_Parser.* files so that
	  templates would be split from the non-templates.  This avoids
	  bugs with some C++ compilers...

	* ChangeLog: added the ACE_TEMPLATES_REQUIRE_SPECIALIZATION flag
	  to the config-linux-pthreads.h file.  Thanks to
	  Jean-Francois.Ripouteau@netsurf.org for reporting this, and also
	  for archiving the ACE mailing list.

Thu Apr 11 01:37:25 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Released version 4.0.9 for testing.

	* ace: regenerated all the manual pages and html pages.

        * Built ACE successfully on SGI IRIX 5.3 using GNU G++ 2.7.2.
	
	* ace/Thread_Manager: renamed the descriptor() accessor methods to
	  hthread_descriptor() and thread_descriptor() to avoid
	  ambiguities due to the fact that hthread_t and thread_t can now
	  be the same type.

	* ace/Thread_Manager: revised the hthread_t so that it is always
	  large enough to hold valid thread ids.

        * ace: Moved the config-osf1.h file to be named config-osf1-3.2.h
	  in anticipation of OSF/1 4.0...

        * ace: Changed all occurrences of wchar_t to ACE_USHORT16, which
	  is a more portable way of representing wchar_t's so that we can
	  pass them across the network...  Unfortunately, wchar_t tends to
	  be different sizes on different machines, so we can't use the
	  binary form!!!

        * ace: Added many, many small changes to get ACE to compile on
	  OSF/1 3.2D using DEC C++ 5.3.  Thanks to Tom Marrs
	  <0002104588@mcimail.com> for slogging through all of this stuff!

	* ace/Thread_Manager.h: Fixed a stupid oversight where I forgot to
	  add a -1 to the trailing argument of spawn*.  Thanks to Neil
	  Cohen for spotting this.

	* ace: Added a new ACE config file for AIX 3.2.5 courtesy of Bob
	  Olson <olson@mcs.anl.gov>.  In addition, I changed the name of the
	  config-aix.h file to be config-aix-4.1.x.h and called the new
	  file config-aix-3.2.5.h.

	* apps/Synch-Benchmarks/Benchmark.cpp: Added template
	  specializations for ACE_TSS and ACE_Atomic_Op.  Thanks to Matt
	  Stevens for pointing out the need for this.

	* ace/CORBA_Handler: Added a number of fixes to get the ACE
	  CORBA_Handler to compile on Win32 with Orbix 2.0.  Thanks to
	  Rich Ryan <rryan@mseng.kla.com> for these fixes.

	* ace/OS.cpp (thr_create): Fixed a small bug in the pthreads
	  thr_create() code by dereferencing p_thr before casting it
	  to hthread_t and assigning it to *thr_handle.

	* ace/OS.i: Backed out the previous changes of pthread_cleanup*.
	  It turns out that on SunOS 5.5 these macros force a certain
	  style of programming this is hard to integrate with the existing
	  implementations of other ACE wrapper methods.  Fortunately, none
	  of this affects existing ACE code since we just use the default
	  solaris threads API in this case...

	* ace/OS.i: Modified the order of #ifdefs in various ACE_OS::thr_*
	  methods to take advantage of the pthreads features on Solaris
	  2.5.

        * ace: Removed the last few typos that prevented ACE from building
	  on SunOS 4.x with G++...

	* ace/Thread_Manager: Changed spawn() and spawn_n() so that
	  they optionally take a group parameter and automatically add 
	  this to an existing thread group.  That way we don't need to
	  spawn the thread(s) and then reassign them after the fact.  
	  The new API automatically assigns the thread(s) to the group 
	  you specify.  Thanks to Chris Lahey for this idea.

        * ace: Fully integrated POSIX pthreads into the ACE build for
	  Solaris 2.5.

	* netsvcs/lib/Server_Logging_Handler.cpp: Rearranged the Server
	  Logging files so that things will compile and link correctly
	  using stock GNU G++.

	* ace/Log_Msg.cpp (ACE_Log_Msg): Forgot to initialize the ostream
	  * to 0.  This was causing problems for Win32...

	* ace: *Finally* got the static and dynamic ACE libraries to
	  compile on SunOS 4.x using stock G++! 

	* ace/Synch_T.h: Added a new macro called ACE_SYNCH that will
	  be ACE_NULL_SYNCH if !ACE_HAS_THREADS and ACE_MT_SYNCH if
	  ACE_HAS_THREADS.

	* ace/Service_Record.cpp: Changed this to use ACE_SYNCH.  This
	  will fix template problems with G++ on SunOS 4.x.

	* build/SunOS5.5/ace/OS.i (sema_wait): Changed all uses of
	  ::pthread_cleanup_{push,pop} to pthread_cleanup_{push,pop} since
	  these are implemented as macros on Solaris....

Thu Apr 11 19:43:33 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* examples/Naming/Dump_Restore/Dump_Restore.cpp (init): Modified
	  Dump_Restore in order to work correctly without having
	  Name_Options around as a Singleton.

	* examples/Naming/Client/Client_Test.cpp (set_host): Modified
	  Client_Test in order to work correctly without having
	  Name_Options around as a Singleton. It simply uses the accessor
	  provided by Naming_Context to get to Name_Options.

	* ace/Name_Options.cpp: Changed Name_Options so that it is no
	  longer a Singleton. As a result, now there is an instance of
	  Name_Options per Naming_Context. Note that for an application to
	  change Name_Options, it can use the accessor function provided
	  in Naming_Context. As a consequence of all these changes, we can
	  now have multiple Naming_Contexts per application.	  

Wed Apr 10 20:19:50 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * ace/OS.h: Incorporated a mapping for Solaris 2.5 pthreads so
	  that it fits in nicely with the earlier ACE pthreads support.
	  From now on, the pthreads API will be the default threading
	  scheme for ACE on Solaris 2.5...

	* ace: Added the file name to every *.cpp and *.i file in ACE.
	  This makes it easier to figure out what's what when looking at
	  the source code.  Thanks to Chris Lahey for suggesting this.

	* ace/CORBA_Handler.cpp (ACE_CORBA_Handler): Added bodies for
	  the copy constructor and assignment operator of ACE_CORBA_Handler
	  (which are private) since some compilers generate link errors
	  for these!  Thanks to Rich Ryan <rryan@mseng.kla.com> for
	  pointing this out.
	  
	* ace/Synch_T.cpp (ts_get): at line 270 (within
	  ACE_TSS<TYPE>::ts_get (void) const) there was a keycreate() call
	  that did not have an instance pointer pass in with it.  The
	  symptom has been that if the last active task has been finished
	  all active tasks being created afterwards won't get the close()
	  hook invoked.  I've fixed this in order to solve a mysterious
	  bug with ACE_TSS.  Thanks to the ever-vigilant Detlef for
	  reporting this bug and fix.

Wed Apr 10 01:56:52 1996  Douglas C. Schmidt  (schmidt@mambo.cs.wustl.edu)

        * ace: Added the ACE_TEMPLATES_REQUIRE_SPECIALIZATION to
	  config-sunos5.5-g++.h file.  This should allow ACE to build
	  correctly.  Thanks to Adam Miller <adam@royalblueny.com> for
          pointing this out.

        * ace: Installed SunOS 5.5, so now we can finally test pthreads!

	* ace/OS: Modified the implementation of mutex_t for Win32 so that
	  it automatically selects the CRITICAL_SECTION or the HANDLE form
	  of Mutex depending on whether the type argument is USYNC_THREAD
	  or USYNC_PROCESS, respectively.  This now means that all the
	  existing ACE code that used ACE_Condition<ACE_Mutex> will
	  continue to work correctly on Win32 and UNIX!

Tue Apr  9 23:04:30 1996  Douglas C. Schmidt  (schmidt@mambo.cs.wustl.edu)

	* ace/Synch: Somehow, the definitions for ACE_Thread_Semaphore and
	  ACE_Process_Semaphore were MIA.  I've added the implementations.
	  Thanks to Bruce Worden <bruce@betsy.gps.caltech.edu> for
	  noticing this...

Tue Apr  9 02:16:02 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * ace/Service_Config.cpp: reordered the #includes in this file so
	  that it works correctly on Win32.  Thanks to Rich Ryan
	  <rryan@mseng.kla.com> for help with this.

	* ace/Auto_Ptr.cpp (remove): added the implementations of the
	  auto_ptr::remove() and auto_array_ptr::remove() static methods.
	  Thanks to Chris Lahey for noticing their absence...

	* ace/Auto_Ptr: Added the #pragma implementation ("Auto_Ptr.cpp")
	  statement if defined ACE_TEMPLATES_REQUIRE_PRAGMA to work on
	  AIX.  Thanks to Chris Lahey for this.

	* ace/Makefile: Moved Auto_Ptr from FILES to TEMPLATE_FILES to
	  work on AIX.  Thanks to Chris Lahey for pointing this out.

	* Modified a bunch of the apps and example Makefiles so that
	  things will build better using G++.

	* ace/Name_Options.cpp (parse_args): Made the "database" name the
	  same as the process name by default...

	* ace/Reactor.h: Changed the type of current_ in
	  ACE_Handler_Repository_Iterator from size_t to ssize_t so that
	  this can handle negative numbers.  Thanks to Mark Zusman
	  <marklz@rotem.technion.ac.il> for reporting this.

Mon Apr  8 23:33:15 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* netsvcs/lib/Name_Handler.cpp (recv_request): Fixed a small
	  bug. In recv_request() ntohl was being called again on length
	  which was causing problems since the length was already in host
	  byte order.  The ACE Name Server should now be working on NT.

Mon Apr  8 02:14:30 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace: Fixed a number of minor problems that caused duplicate
	  symbols when linking ACE with G++ (no-repo) on SunOS 5.x and
	  SunOS 4.x.  Thanks to Andy Gokhale for help with this.

	* ace: Added Jan Rychter <jwr@icm.edu.pl> very nice contribution
	  of pthreads and DCE threads to ACE.  This should make life
	  easier for Linux users and users of other pthreads packages.

	* ace/Service_Config.cpp (process_directives): Changed the code to
	  use an auto_ptr to make sure that we always release the
	  ace_obstack memory, regardless of how we exit.

	* ace/OS.i (strerror): Changed sys_errlist to _sys_errlist to work
	  around bugs with SunOS 4.x.  This will undoubted break some
	  other twisted UNIX system.

	* ace/Local_Tokens.cpp (acquire): Added a return 0 at the very
	  end...  Thanks to Chris Lahey for reporting this (yet
	  again... ;-)).

	* ace/Parse_Node: Made a bunch of small changes to deal with the
	  fact that there's no dlerror() equivalent on NT...

	* ace/Task.h: The static function instance() should return
	  ACE_Task_Exit<ACE_SYNCH_1>* (or <ACE_SYNCH_2>), not
	  ACE_Task_Exit *.  Thanks to Chris Lahey for spotting this.

	* ace/Thread_Manager.cpp: added an argument to the exit() method
	  that allows applications to exit without calling thr_exit.  This
	  would allow the method to be called from within a pthread
	  cancellation cleanup routine, without calling thr_exit a 2nd
	  time.  Thanks to Chris Lahey for suggesting this.

	* ace/Log_Record.cpp (operator <<): Changed the verbose option so
	  that it is an attribute, this will allow the ostream to print
	  verbose information if necessary.  Thanks to Chris Lahey for
	  suggesting this change.

	* ace/config-win32-msvc*.h: Added the
	  ACE_LACKS_STATIC_DATA_MEMBER_TEMPLATES flag since it appears
	  that this causes problem with some versions of MSVC++ 4.0...

	* Released version 4.0.6 for testing.

	* netsvcs/lib/Server_Logging_Handler.h: #included the
	  Svc_Handler.h file, that absence of which was causing problems
	  for HP/UX.  Thanks to Richard Orr
	  <rorr@costello.den.csci.csc.com> for reporting this.

	* Made a few minor changes to the source to make sure that it
	  compiles correctly on SunOS 5.x with G++.

	* ace/Thread_Manager.h: Added the insert() method for the non-MT
	  version of Thread_Manager.  Thanks to Alexandre Karev
	  <akg@na47sun05.cern.ch> for reporting this.

	* ace/Task: Renamed the static double-check lock_ to
	  ace_task_lock_ to avoid a name conflict with the existing
	  this->lock_ instance in each class.  Thanks to Prashant for
	  tracking this down...

Sun Apr  7 14:40:05 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp:
	  Rolled back a change that replaced #defines with typedefs.  It
	  turned out the #defines were there for a reason...  Thanks Neil
	  B. Cohen <nbc@metsci.com> for pointing this out...

	* ace/OS.h: Added a new check to deal with the fact that many
	  versions of Pthreads don't support tid_t (which seems to be an
	  AIXism...).

Thu Apr  4 01:19:19 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * Officially released version 4.0.5...

	* ace/OS.h (ACE_TSS_TYPE): Somehow the ACE_TSS_TYPE macros ended
	  up *before* the inclusion of Time_Value.h, which meant that
	  these macros weren't being expanded properly.  This may help
	  explain odd behavior with ACE TSS.

	* ace/Thread_Manager.cpp (insert): Added a new method that allows
	  us to insert a thread into an ACE_Thread_Control after it's been
	  constructed.

	* ace/Message_Block: Fixed a typo in the init() method.  Thanks to
	  Ross Dargahi <rossd@krinfo.com> for noticing this.

	* ChangeLog: Finally got all of ACE built on SunOS 5.x and SunOS
	  4.x using only the stock GNU GCC compiler (i.e., no template
	  repository...).  This should make it easier to port to other
	  versions of G++.

	* ace/Task: Modified the ACE_Task and ACE_Task_Exit implemenation
	  so that it only uses 1 TSS key per ACE_Task template
	  instantation, rather than 1 TSS key per ACE_Task instance.  This
	  works around horrible limitations with Win32...

	* ace/Thread_Manager: Added new methods to set and get the
	  Thread_Manager used in a Thread_Control.

	* ace/Pipe.cpp (open): Fixed a bug in where ACE_Pipe::open did not
	  set this->handles_, thus a garbage handle gets registered.
	  Inserted the following two lines at line 53 of Pipe.cpp:

	  this->handles_[0] = reader.get_handle ();
	  this->handles_[1] = writer.get_handle ();

	  Thanks to Kirk Sinnard <kirk.sinnard@lawson.com> for this fix.

	* ace/OS.h: Added a couple of fixes for the SCO port.  Thanks
	  again to Matt Newhook <matthew@neweast.ca>

	* ace/OS.cpp: Integrated Detlef's clever scheme for freeing up
	  thread-specific storage correctly on Win32...

	* ace/Task.cpp (ACE_Task): Made sure to initialize the
	  next_-pointer of ACE_TASK and Message_Queue point to NULL.
	  This fixes a problem on NT.  Thanks to Karlheinz for 
	  noticing this...

	* include/makeinclude/rules.lib.GNU (VLIB): Fixed up the ACE
	  makefiles so that we can now build on SunOS 4.x correctly
	  without using the template repositories...

	* ace/Service_Config.cpp: Added a bunch of template
	  specializations so that GNU G++ can be used to compile ACE on
	  SunOS 4.x *without* requiring the template repository hacks...
	  Thanks to Mark Zusman for helping with this.

Wed Apr  3 00:55:12 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* examples/Reactor/Misc/test_reactors.cpp: Added a new torture
	  test of the ACE_Reactor and ACE_Task.  Thanks to Detlef for
	  contributing this...

	* netsvcs/bin/Makefile: Removed a stray -lACE_svcs from the
	  Makefile.  Thanks to Matt Stevens for reporting this.

	* ace/Synch.cpp: Fixed two mistakes related to keeping INLINE on
	  the get_thread_id() and get_nesting_level() when I moved them
	  into the *.cpp file...  Thanks to Matt Stevens for finding this.

	* ace/Reactor.cpp (owner): modified owner() so that it returns
	  the original owner when setting a new owner.  This makes it
	  possible to write code like this:
	  
	  thread_t t;
	  
	  reactor->owner (ACE_Thread::self (), &t);
	  reactor->handle_events ();
	  reactor->owner (t);

	* ace/SOCK_Connector.cpp (connect): Added an additional check for
	  errno == EWOULDBLOCK for non-blocking connects due to screwy
	  semantics of Win32 non-blocking sockets...

	* netsvcs/lib/Client_Logging_Handler: Fixed a very obscure bug
	  that arose due to the way that UNIX select() interacts with
	  SVR4 MSG_BAND data.  It turns out that you must use the
	  ACE_Event_Handler::EXCEPT_MASK to get this to work properly
	  (gag).  This stuff is much easier with SVR4 poll().

Tue Apr  2 13:57:05 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.i: Fixed an error compiling the new Log_Msg.cpp because
	  when it inlined OS.i, there were references to
	  ACE_OS::thread_mutex_*() before the functions were declared
	  inline.  The references were assumed to be external, and then
	  when the linkage was actually declared as inline, the compiler
	  choked.  To fix this, in OS.i, all the thread_mutex_* calls
	  where moved above the first reference, which was in
	  ACE_OS::cond_broadcast().  Also moved the mutex*() calls since
	  they are referenced by the thread_mutex calls.  So the order is
	  mutex*(), then thread_mutex*(), and then cond*().  Thanks to
	  Chris Lahey for reporting this.

	* netsvcs/lib/Client_Logging_Handler.cpp: Added missing return
	  values in some of the methods.  Thanks to Tim Harrison for
	  spotting this...

	* ace/Map_Manager.cpp (shared_unbind): It was possible that INT_ID
	  could be assigned a value from a previously unbound map entry.
	  The shared_unbind matches the ext_id, but does not see if the
	  entry had previously been unbound.  This causes a problem if the
	  INT_ID type is a pointer type, and the user of the map deletes
	  objects as a result of the unbind returning a 0.  The correct
	  solution is to include a test for is_free in the shared_unbind
	  before checking the equality of the ext_id.  Thanks to Phil
	  Mesnier <phil@envision.com> for reporting this.

	* ace/Reactor.cpp (next): Fixed a bug that prevented the
	  iterator's next() method from detecting the end of the
	  iteration.  Thanks to Mark Zusman <marklz@rotem.technion.ac.il>
	  for reporting this.

	* ace/Reactor.cpp (advance): Fixed a bug that prevented the
	  iterator from advancing.  Thanks to Mark Zusman
	  <marklz@rotem.technion.ac.il> for reporting this.

	* ace/Log_Msg.cpp (open): Added a check for logger_key being NULL,
	  in which case we log to STDERR rather than segfault...

	* netsvcs/lib/Server_Logging_Handler.h: Fixed a typo in
	  the declaration of
	  
	  ACE_SVC_FACTORY_DECLARE (ACE_Server_Logging_Acceptor)
	  
	  Thanks to Neil Cohen for finding this.

Mon Apr  1 00:17:21 1996  Douglas C. Schmidt  (schmidt@mambo.cs.wustl.edu)

	* ace/Time_Value.i: Fixed two stupid bugs in the Time_Value
	  relational operators.  Thanks to Mathew Newhook
	  <matthew@thor.udc.neweast.ca> for pointing this out.

	* ace/OS.h: Added an extern "C" block around the netdb, net/if.h,
	  netinet/in.h, arpa/inet.h to work around problems with SCO.
	  Thanks to Mathew Newhook <matthew@thor.udc.neweast.ca> for this.

	* ace/Reactor: Merged the ACE_Pipe into the Reactor
	  implementation.  This cleans up some nasty OS-specific code in a
	  clean way.

	* ace/CORBA_Handler.cpp (ACE_MT_CORBA_Handler): Fixed some typos
	  that arose during the transition to the ACE_Pipe.

	* ace/Pipe: Added a new open() method that doesn't return the
	  handles, it just stashes them away for safe keeping.  This is
	  useful for places like the Reactor.

	* ace/Local_Name_Space.h: Added ACE_Export to the front of
	  ACE_NS_String.  Thanks to Detlef for suggesting this.

        * From now on, I'll be numbering each new release of ACE with a
	  different minor number.  However, the latest version of ACE will
	  also always be available at

	  http://www.cs.wustl.edu/~schmidt/ACE.tar.gz

	  This is useful if you just want to get the latest one without
	  having to bother with keeping track of minor numbers.  For
	  instance, that way you can still keep that reference in my
	  bookmark list and you don't have to remodify it with every
	  release.  Thanks to the ever-vigilant Chris Lahey for suggesting
	  this.

        * ace: added new a ACE project file (ace.mdp) and Makefile
	  (ace.mak) to create ACE as a DLL on Win32.  This should greatly
	  simplify the Win32 build process...

	* INSTALL: Added new INSTALL file explaining how to build for
	  Win32.  

	* ace/Thread_Manager.cpp: Fixed a horrible bug with Win32.  On
	  reasonable systems ACE_Thread::exit() should not return.
	  However, due to horrible semantics with Win32 thread-specific
	  storage this call can return (don't ask...).  Therefore, we need
	  to reacquire the mutex so that we don't get burned when the
	  Guard automatically releases it when this method returns.  Thanks
	  to Tim for helping me figure this out.

        * ace: Fixed some problems with errno in Remote_Tokens and
	  Local_Tokens.

	* ace/Reactor.cpp: Fixed an annoying preponderance of useless
	  ACE_MT_SAFE #ifdefs in the Reactor implementation.  Thanks to
	  Gerolf Wendland <wendland@hpp015.mch2.scn.de> for pointing this
	  out!

Sun Mar 31 13:09:27 1996  Douglas C. Schmidt  (schmidt@mambo.cs.wustl.edu)

	* ace/OS: Changed the implementation of cond_t and rwlock_t for
	  Win32 to use thread_mutex_t (i.e., CRITICAL_SECTIONS) rather
	  than mutex_t (i.e., Win32 Mutexes).  This should improve
	  performance without sacrificing generality (of which there is
	  none at the moment since we don't have process-wide condition
	  variables or readers/writer locks on Win32 anyway..

	* ace/Thread_Manager.cpp (remove_thr): Fixed bugs in the
	  ACE_Thread_Manager class.  The wait() member grabbed the
	  Thread_Mutex lock_, then (if the current_count is not zero)
	  grabs the Condition lock zero_cond_.  Doing so, however
	  implicitly released lock_, which meant that another thread could
	  get into wait(), and wait on zero_cond_.  zero_cond_ was only
	  signaled from ACE_Thread_Manager::remove_thr() when the
	  current_count_ is zero, but it signaled with
	  ACE_Condition_Thread_Mutex::signal(), which only releases one
	  thread that is waiting on the Mutex.  Thus, any other threads
	  waiting on zero_cond_ would never be resumed.  The fix was to
	  use ACE_Condition_Thread_Mutex::broadcast() rather than
	  ACE_Condition_Thread_Mutex::signal() in
	  ACE_Thread_Manager::remove_thr().  This fix is only reliable
	  since remove_thr() is called only when ACE_Thread_Manager::lock_
	  is held by the calling thread.  Thank to Bruce Worden
	  <bruce@seismo.gps.caltech.edu> for reporting problem and
	  suggesting this fix.

	* ace/Token: Modified this class so that it only works with
	  ACE_Thread_Mutex (which is more precise than what was going on
	  before...).

	* ace/Synch.h: Modified ACE_RW_Process_Mutex so that on Win32 it
	  uses ACE_Process_Mutex until we've got a working
	  RW_Process_Mutex for Win32...

	* ace/Synch: Removed the ACE_Process_Barrier until we get a
	  working implementation...

	* ace/Synch: Changed the ACE_Barrier so that it only tries to work
	  within a single process.

        * ace: Changed all uses of ACE_Condition_Mutex to
	  ACE_Condition_Thread_Mutex to reflect what's really going on
	  here...

	* Changed all uses of ACE_Mutex to ACE_Thread_Mutex throughout
	  ACE.  This is *much* more meaningful and makes it possible to do
	  some great optimizations on Win32!

	* ace: Changed all uses of ACE_Mutex_Guard to
	  ACE_Thread_Mutex_Guard.  This is a more accurate name for how
	  this is used in ACE.

	* netsvcs/lib/Client_Logging_Server: Reengineered the ACE
	  Client_Logging service so that fits into the ACE network service
	  format.  This version is particularly interesting since it
	  illustrates a "Connector-driven" service.  In contrast, all the
	  other ACE network services are "Acceptor-driven" services.

	* netsvcs: Merged the implementation of all the ACE network
	  services into a single ./netsvcs/lib directory.  Each of these
	  is now a fully dynamically linkable service.  Created a single
	  main.cpp program in the ./netsvcs/bin directory.  This main
	  illustrates how to dynamically link an or all of the ACE network
	  services to form complete applications.  Thanks to Prashant for
	  help with this.

	* ace/OS.cpp: Changed readv() and writev() so that they will once
	  again compile for Win32.  Note, however, that if you try to
	  readv() and writev() on the same descriptor you will lose since
	  they are not atomic!  However, this stuff is stuff useful if
	  you're *not* reading/writing to a common descriptor...

	* ace/Synch_T.cpp: Removed the ACE_Null_Condition<> template.
	  This didn't really make any sense...

        * ace/OS: Changed the test of lock_.get_nesting_level() in
	  ACE_TSS_Cleanup::exit () to account for the fact that a
	  ACE_Recursive_Thread_Mutex now starts out with a nesting level
	  of 1 when it is first acquired.

        * ace/Synch_T: Removed the implementation of ACE_Recursive_Lock.
	  It just doesn't generalize correctly to other types of
	  synchronization mechanisms...

        * ace/Synch: Reimplemented ACE_Recursive_Thread_Mutex using Dave
	  Butenhof's <butenhof@zko.dec.com> strategy.  This fixes some
	  latent race conditions in the original implementation.

	* ace: Changed the name of ACE_Recursive_Mutex to
	  ACE_Recursive_Thread_Mutex since the current implementation
	  really only works for Thread_Mutexes or Thread_RW_Mutexes...

	* ace: Removed the "Assert.h" file and moved its functionality
	  into Log_Msg.h.  This is more consistent with the rest of the
	  error reporting and logging in ACE and also avoids some nasty
	  circular include problems.

	* ace/Local_Tokens.cpp: Changed the use of ACE_RETURN so that it
	  passes in errno.
	
	* ace/Log_Msg: Changed the arguments to the ACE_RETURN macro so
	  that errno can be returned explicitly.

Sun Mar 31 15:52:58 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Local_Name_Space.cpp (create_manager): Added three new
	  methods -- list_name_entries, list_name_values, and
	  list_name_types. They work similar to list_names, list_values,
	  and list_types (respectively) except they return the entire
	  tuple associated with a name binding.

Sat Mar 30 16:46:32 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/SPIPE_Stream.i (send_handle): There was a typo -- the
	  parameter shouldn't be "const ACE_HANDLE handle", it should
	  just be ACE_HANDLE handle.

Sat Mar 30 16:09:25 1996  Douglas C. Schmidt  (schmidt@mambo.cs.wustl.edu)

	* INSTALL: Added new Win32 installation instructions to build
	  ACE as a DLL.

Sat Mar 30 14:42:02 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Carefully tested ACE on SGI and SunOS 5.x using G++ and CC.
	  Everything seems to work now...  Released version 4.0.2.

	* ace/Acceptor.cpp (ACE_Strategy_Acceptor): Added default
	  initializations of NULL for service_name_ and
	  service_description_ in the ACE_Strategy_Acceptor's default
	  constructor.

	* ace: Fixed a slew of warnings for HP/UX.  Thanks to John Morey
	  for reporting these.

	* ace/FILE.h (ACE_FILE_Info): Changed the type of field size_ from
	  size_t to off_t to avoid warnings from C++ compilers...

	* ace/OS.cpp (ftruncate): Added a new function for platforms like
	  SCO that lack ftruncate().  Thanks to Matthew Newhook
	  <matthew@neweast.ca> for contributing this.

Sat Mar 30 12:41:16 1996  Douglas C. Schmidt  <schmidt@pride.cs.wustl.edu>

        * ace: Removed the ACE_svcs library for the time being and merged
	  everything back into libACE.  There were two reasons for this
	  change:
	  
	  1. There is a subtle dependency between the ACE_Reactor and the
	     ACE_Local_Tokens* stuff when deadlock detection is enabled.
	     This was causing problems.

	  2. This was driving GNU G++ nuts because of the need to 
	     do the "prelink."

	  Sooo, for the time being, there's just one ACE library.  If
	  anyone wants to take the time to split everything up so that it
	  works for all different platforms and send me the fixes I'll be
	  glad to include this in ACE.

	* ace/Thread.i: Made the ACE_Thread::thr_self() methods call
	  down to the ACE_OS::thr_self() methods for the case where
	  the platform doesn't support threads.  This means that we
	  only have to set the default thread id in one place...

Sat Mar 30 11:53:31 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* bin/class2info.awk: Modified the handleClass() AWK function so
	  that it can correctly deal with the new ACE_Export and
	  ACE_Svc_Export tags needed to build ACE DLLs...  Here's the
	  trick:

	  sub( "^[\t ]*class[\t ]+(ACE_[.]*Export[\t ]+)?", "", $0 )

	  completely intuitive, eh? ;-)

	* apps/Gateway: Reimplemented the Gateway prototype so that it
	  uses the new Reactor cancel_wakeup() and schedule_wakeup()
	  methods instead of mask_ops().

	* ace/Reactor: Added new high-level <Event_Handler> "scheduling"
	  operations called schedule_wakeup() and cancel_wakeup().  These
	  methods utilize the lower-level Reactor mask_ops() methods to
	  schedule and cancel Event_Handlers for subsequent dispatching by
	  the Reactor.  I added these new interfaces because they are more
	  intuitive than calling mask_ops(), which is a non-descriptive
	  name unless you understand the Reactor implementation...

	* ace/config-irix5.*.h: It turns out that on IRIX 5.x the
	  bi-directional SVR4 pipe semantics are *disabled* by default.
	  Therefore, I've changed the config-irix4.*.h files to comment
	  out ACE_HAS_STREAM_PIPES.

Fri Mar 29 08:25:33 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/ACE.cpp (ldfind): Changed the character given to strtok() to
	  account for the differences in UNIX and Win32 described in the
	  follow bullet.

	* ace/OS.h: UNIX and Win32 use different characters to separate
	  pathnames in their runtime LD search path (':' and ';'
	  respectively).  Therefore, I've added new macros to ACE OS to
	  account for this stuff portably.  

	* ace/OS.i: Changed the behavior of the ACE_OS::thr_self() methods
	  so that they always return 1 if ACE_HAS_THREADS is *not*
	  enabled.  This makes application code work correctly across
	  threaded and non-threaded platforms.

	* ace/OS.i: Changed the return value of the Win32 arm of the
	  ACE_OS::dlopen() and ACE_OS::dlsym() functions so that they are
	  now identical to the way that UNIX behaves.

	* ace/Svc_Conf.y: added a #define for ACE_BUILD_DLL to make Win32
	  happy...

	* ace/Synch.i: Fixed a number of bugs in the ACE_Mutex and
	  ACE_Thread_Mutex tryacquire_read() and tryacquire_write()
	  methods.  I was calling mutex_lock() rather than
	  mutex_trylock()!  Thanks to Prashant for finding this.

	* ace/OS.cpp (exit): Fixed a bug caused by the fact that the test
	  for the nesting level of the recursive mutex should have been
	  for > 0 rather than > 1.  Thanks to Kirk Sinnard
	  <1764@mn.lawson.lawson.com> for tracking this down!

	* ace/Log_Msg: Enhanced ACE_Log_Msg so that it automatically
	  caches the process id.  This makes it more robust even if users
	  don't call open()!

	* examples/Connection/non_blocking/CPP-connector.cpp Fixed a bunch
	  of typos that caused templates to fail on HP/UX.  Thanks to Neil
	  Cohen for spotting this.

	* ace/Shared_Memory_SV: Change all uses of "int id" to "key_t id"
	  to reflect the new use of key_t in the Memory_Pool.

	* ace/Memory_Pool.cpp (ACE_MMAP_Memory_Pool): Fixed a potential
	  but in the construction of an MMAP memory pool.  Because NT uses
	  strings rather than integers to name its semaphores we were
	  passing in junk to the NT Process_Mutex initializer.  Arrgh!  I
	  fixed this problem by typedef'ing key_t to be char * on Win32
	  and then updating the ACE_DEFAULT_SEM_KEY to be
	  "C:\\temp\ace.sem" rather than 1234....  Also added a new macro
	  called ACE_INVALID_SEM_KEY, which is NULL on NT and -1 on UNIX.

	* ace/Log_Msg.cpp (instance): Fixed a typo for HP/UX and
	  other non-threaded platforms!

	* ace/Synch_T.cpp (ACE_TSS_Guard): Added another small fix
	  to ACE_TSS_Guard to make sure we free up the key when we 
	  go away.

Thu Mar 28 15:28:44 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.h: changed the names of macros ACE_DYNAMIC_SVC* to new
	  names that reflect their new, more general nature now that we've
	  got the ACE_Static_Svcs stuff...

	* ace/Service_Config.cpp (load_defaults): Added a very nice
	  mechanism that generalizes the configuration of statically
	  linked services.  This makes it possible to insert statically
	  linked services into a program without changing any of the
	  existing ACE_Service_Config code.  These static services can
	  then be enabled via the svc.conf file using the "static"
	  directive.  Thanks to Matthew Newhook <matthew@neweast.ca> for
	  suggesting this and for doing the bulk of the implementation.

	* ace: Commented out the ACE_TRACE calls in ACE_Unbounded_Set,
	  ACE_OS, and all the ACE synchronization wrappers to work around
	  some horrible dependencies with Win32 and thread-specific
	  storage...  The moral here is that you have to be careful what
	  you trace because circualar dependencies abound...  My new
	  policy is that low-level routines are not automatically traced
	  because they can cause infinite recursion.

	* ace/Synch_T.cpp: Fixed a nasty bug with ACE_TSS_Guard.  This was
	  causing programs that uses ACE_TSS_Guard to segfault...  Thanks
	  to Kirk Sinnard <kirk.sinnard@lawson.com> for reporting this.

	* ace/Synch: Added "lock()" methods to all the ACE synchronization
	  wrappers to return the underlying C level object...  This is
	  necessary at some points in ACE.

	* ace/Synch: Fixed a horrible bug in ACE_Recursive_Mutex and
	  ACE_Recursive_Lock that was causing instant deadlock because the
	  non-recursive Solaris/Pthread mutex was being acquired too
	  eagerly...

Thu Mar 28 12:14:57 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Map_Manager.cpp (rebind): Added a new method called resize()
	  which increases the size of the map. Both open() and
	  shared_bind() make use of this method to dynamically increase
	  the size of the map.

	* ace/Local_Name_Space.cpp (shared_bind): Modified shared_bind()
	  in accordance to the changes to Map_Manager. shared_bind() no
	  longer has to check if the map runs out of room since
	  Map_Manager dynamically grows the map.

	* ace/Map_Manager.cpp (shared_bind): Changed shared_bind() so that
	  when the map reaches max_size_, we grow the map by DEFAULT_SIZE
	  by making a call to open().

Wed Mar 27 20:00:47 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Local_Name_Space.cpp (shared_bind): Fixed a bug which was
	  allocating memory for a name binding which would fail on a bind
	  since there already existed a binding. This was causing the
	  mapped-file to grow even when binds would fail.

Tue Mar 26 13:49:24 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/INET_Addr.i (addr_to_string): Moved the order of
	  get_host_addr() so that it comes before addr_to_string().
	  Thanks to Neil Cohen for finding this.

	* ace/Synch: Added a new implementation of ACE_Thread_Mutex that
	  takes advantage of the new ACE_OS::thread_mutex_* mechanisms.

	* ace/OS: Added a new set of ACE_OS::thread_mutex_* mechanisms
	  that map efficiently to either Win32 CRITICAL_SECTIONs or UNIX
	  mutex_t's with type set to USYNC_THREAD.  This allows ACE to
	  take advantage of the lightweight Win32 synchronization
	  mechanisms.  When Windows NT 4.0 comes out, we'll at last have a
	  perfect mapping since WinNT 4.0 supports
	  TryEnterCriticalSection!

Tue Mar 26 17:35:31 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Map_Manager.cpp: Added two new methods -- total_size() and
	  current_size() which return the max_size and current_size of the
	  map respectively.

Mon Mar 25 20:22:25 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Service_Config.cpp (initialize): Updated the use of ACE_ARGV
	  to use the new method names.

	* ace/ARGV.cpp (ACE_ARGV): Changed the name of the two main
	  methods of ACE_ARGC from count() and operator&() to argc() and
	  argv().  This seems much more consistent with UNIX and C/C++
	  naming conventions.

	* ace/ARGV.cpp (ACE_ARGV): Added environment variable substitution
	  to the ACE_ARGV class using the new ACE::strenvdup() method.
	  This is transparently available to the ACE Service Configurator
	  now, which enables the svc.conf file to include things like
	  this:

	  dynamic Name_Service Service_Object *
	     name_svc.so:make_Name_Service() "-p $PORT -h $HOST"

	* ace/ACE: Added a new function called strenvdup() that returns a
	  dynamically allocated duplicate of its <str> argument,
	  substituting the environment variable if str[0] == '$'.

	* ace/Naming_Context: Modified this class so that it now inherits
	  from ACE_Service_Config.  This enables application programmers
	  to dynamically link instances of ACE_Naming_Context into their
	  applications via the svc.conf file.

	* ace/OS.i (access): Added a new wrapper for the access() method.

	* ace/Local_Name_Space.cpp: Fixed an error in each list_xxx
	  methods.  If there's an error in the for-loop we must still call
	  ACE_OS::free() to release resources.  Thanks to the
	  ever-vigilant Karlheinz Dorn for spotting this.

	* ace/Strategies: added virtual methods with name dump() to
	  ACE_Scheduling_Strategy, ACE_Schedule_All_Reactive_Strategy, and
	  ACE_Schedule_All_Threaded_Strategy.  These methods are
	  referenced in ACE_Strategy_Acceptor::dump() method
	  (Acceptor.cpp).  Thanks to Alexandre Karev for reporting this.

        * include/makeinclude: Added a number of changes to allow ACE to
	  build shared libraries correctly on AIX.  Thanks to Chris Lahey
	  for these fixes.

	* ace/Makefile: added tempinc to the list of directories to delete
	  for "clean".  Also, between the call to the two sub make files,
	  added a $(RM) -rf tempinc.  Since we make both libs from the
	  same directory, we need to delete the tempinc directory to be
	  sure we don't get the templates generated for libACE included in
	  libACE_svcs.

	* ace/OS.i: Improved the mapping between ACE Win32 GetLastError()
	  values and POSIX-like errnos.  This is now centralized in the
	  ACE_FAIL_RETURN macro.

	* examples/Threads/test_thread_specific.cpp: Added many new tests
	  to exercise the ACE thread-specific storage mechanisms on Win32
	  and UNIX.

Mon Mar 25 4:00:01 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Name_Options.cpp (parse_args): Added a new data variable
	  called database_ that keeps the name of the name server
	  database. Also added accessor methods for this.

	* ace/Local_Name_Space.cpp (create_manager): Changed
	  create_manager() to use ACE_Name_Options::instance ()->database
	  () instead of ACE_Name_Options::instance ()->process_name().

	* ace/ACE.cpp (ldopen): Added a new method called ldopen that
	  finds a file either using absolute path or using
	  LD_LIBRARY_PATH. If the file is found, it opens the file and
	  returns a pointer to the file.

        * ace/Parse_Node.cpp: used the new ACE::ldfind() method to locate
	  the shared object file.  This makes it possible to put
	  "relative" names into svc.conf files and then allow ACE to
	  locate the appropriate shared object DLL.

        * ace/ACE: added new methods called ldopen() and ldfind() that
	  find the file <filename> either using absolute path or using
	  LD_LIBRARY_PATH.  If found, ldopen() opens the file and returns
	  a pointer to the file.

Sun Mar 24 10:41:12 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Compiled ACE successfully on Windows '95.

	* ace/OS: Totally redid the ACE thread-specific storage cleanup
	  mechanism in OS.cpp to avoid bugs with the previous
	  implementation.

	* ace/Synch_T: Modified ACE_TSS_Guard so that it will call
	  ACE_OS::thr_keyfree () when it's finished.  This should help to
	  eliminate the unbounded use of thread-specific storage slots
	  within a thread.

	* ace/Thread: added a new method keyfree() that calls down to the
	  ACE_OS::thr_keyfree ().

	* ace/Thread_Manager.cpp: Modified the semantics of
          ACE_Thread_Manager::exit () so that it "always" calls
          ACE_Thread::exit () even if the user hasn't registered this
          thread with the thread manager.  This avoids some subtle
          problems that arise typically when I forget to put an
          ACE_Thread_Control around the main() function.

	* examples/Threads/test_thread_specific.cpp: Added new tests to
	  ensure that the Win32 TSS cleanup logic is working correctly!

	* ace/Log_Msg: Moved the definition of the ACE_FIFO_Send_Msg queue
	  from the Log_Msg.h file to the Log_Msg.cpp file.  The MSVC++
	  compiler was having problems with this when building a DLL.
	  Besides, this needs to be replaced with Sockets for Win32
	  anyway...

	* ace/OS.cpp: Put a safe guard in the readv() and writev()
	  emulations so that they return ACE_NOTSUP_RETURN if
	  ACE_HAS_THREADS is enabled.  This is necessary because the
	  readv() and writev() emulations are *not* atomic if multiple
	  threads are used.  If someone can provide an atomic
	  implementation I'll enhance the code to remove the existing
	  restrictions.

	* ace/OS: Created a new macro called ACE_SYSCALL_FAILED, which is
	  mapped to 0xFFFFFFFF on Win32 and -1 on UNIX.

	* ace/Synch and Synch_T: cleaned up the implementation of the
	  Recursive_Lock and Recursive_Mutex to use the ACE_Guard classes.
	  This simplifies the code.

Sat Mar 23 16:53:14 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

        * ace: Updated all ACE classes to use the new ACE_Export macro.
	  This will enable them to transparently be used to create a Win32
	  DLL.  Also added ACE_BUILD_DLL to all the *.cpp files.

	* tests/CPP-inserver.cpp (main): Modified CPP-inclient.cpp and
 	  CPP-inserver.cpp to use non-blocking I/O. In particular,
	  CPP-inserver times out on select and then checks to see if any
	  connections have arrived. Both applications are also working on
	  NT. 

Sat Mar 23 15:02:47 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Local_Tokens.cpp (proxy_): Modified the print statement for
	  local tokens to account for the fact that thread ids can be
	  unsigned on some platforms.

	* ace/Log_Msg.cpp (log): Modified the output format of the %t
	  directive to ACE_Log_Msg::log() so that it prints values in
	  unsigned form rather than signed form.  This fixes a bug with
	  Win32 on Windows '95.

	* ace/ACE: Added two new methods ACE::read_n() and ACE::write_n().
	  These are now necessary since Win32 distinguishes between
	  operations on SOCKETs and operations on other forms of HANDLEs.

	* ace/ACE: Changed all uses of ACE::set_fl() and ACE::clr_fl() to
	  ACE::set_flags() and ACE::clr_flags().

	* ace/ACE: Changed the name of ACE function handle_timed_connect()
	  to handle_timed_open() since this is reall what it does...

Fri Mar 22 00:11:19 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Stack: Added a "Node of last resort" to the
	  ACE_Unbounded_Stack.  This ensures we are graceful in the face
	  of memory failures.

	* ace/OS.i (sleep): Fixed a bug with the Win32 ACE_OS::sleep
	  mapping.  This should have had an "ACE_OSCALL_RETURN" in it...

	* ace/ACE.h: Had forgotten to put "static" in front of "basename".
	  Thanks to Neil Cohen for reporting this...

	* ace/Name_Options.cpp (process_name): Changed char * to const
	  char * to avoid compile error.  Thanks to Neil Cohen for this...

	* ace/IPC_SAP: Implemented the enable()/disable() methods to work
	  with non-blocking I/O for SOCKETs on Windows NT.

	* ace/OS.i: Modified ioctl() to support the ioctlsocket() call on
	  Windows NT.

	* ace/Log_Msg.cpp (log): Fixed a bug that was caused by not
	  NUL-terminating the logging string properly when a %a is given.
	  Thanks to Tim Harrison for finding this.

	* ace/OS: Added a new overloaded "ACE_OS::sleep" method that takes
	  an ACE_Time_Value rather than a u_int.  This is much more useful
	  for fine-grained timers than the horrible UNIX sleep() call.

	* ace/OS.h: #included "sys\timeb.h" in the Win32 version of ACE.

Thu Mar 21 22:18:50 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* apps: Fixed all incorrect usages of ACE_HANDLE = -1 to use
	  ACE_HANDLE = ACE_INVALID_HANDLE in order to work with Win32...

        * ace/OS.i (gettimeofday): Replaced the existing implementation of
          gettimeofday with a new version that is shorter, more efficient,
          and most importantly, correct...  Thanks to Todd Montgomery. and
          Mike Flinn for this stuff.

	* ace/ACE: added a new method called basename() that returns the
	  filename portion of a pathname.

Thu Mar 21 21:51:48 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/OS.h (ACE_DEFAULT_GLOBALNAME): Added some new #defines for
	  NT: ACE_DEFAULT_NAMESPACE_DIR, ACE_DEFAULT_LOCALNAME, and
	  ACE_DEFAULT_GLOBALNAME.

	* ace/Local_Name_Space.cpp (ACE_Local_Name_Space): Fixed a subtle
	  bug. Instead of doing a new char [xxx], I was doing a new char
	  (xxx). Also, added some #if defined (ACE_WIN32) to support
	  special cases for NT (for example determining the context file
	  name). 

Wed Mar 20 02:03:39 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Log_Msg.cpp (log): If we're writing to stdout or to an
	  iostream make sure the lock is help to avoid race conditions and
	  scrambled output.

Tue Mar 19 00:12:25 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Thread_Manager.h: Added new default values to spawn() and
	  spawn_n().

	* ace/OS.i (sigaction): Added support for signals to the ACE NT
	  mapping.

	* ace/ACE: Added 4 new methods to class ACE: send(), send(),
	  recv(), recv().  These calls mask some differences between UNIX
	  and Win32 IPC mechanisms.  Then, reimplemented the Reactor's
	  notification mechanism to use this.

	* ace/OS.i (ACE_OSCALL_RETURN): fixed zillions of warnings on
	  HP/UX by making a small change to line 151 of the OS.i file.
	  Thanks to Neil Cohen for reporting this.

	* ace/Reactor.cpp: Rewrote the Reactor::notify() mechanism to
	  avoid using readv() and writev().  These work fine on UNIX, but
	  don't work correctly on Windows NT due to race conditions.
	  Basically, we need to reimplement this stuff on Win32 to avoid
	  the problem.

	* ace/OS.h: Added SIGQUIT, SIG_BLOCK, SIG_UNBLOCK, and SIG_SETMASK
	  definitions to NT.

	* ace/Time_Value: added a new set() method to be consistent with
	  the ACE_Time_Value (long, long) constructor.

	* ace/Service_Config.cpp (open): Fixed a bug where the
	  ACE_Service_Repository and ACE_Reactor weren't being initialized
	  correctly if the ACE_Service_Config::ACE_Service_Config (const
	  char *) method was called.

	* ace/Service_Config.cpp: Changed the constructor for
	  Service_Config so that it doesn't barf if the svc.conf file
	  isn't found.

Mon Mar 18 00:34:45 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Reactor.h: Hid the inclusion of the Local_Tokens.h file in
	  the Reactor so that by default there will be no dependency
	  between libACE and libACE_svcs.  This should prevent compilation
	  problems on some platforms.

        * bin: Included the html-windex shell script from Vincent Pommier
	  <pommier@volnay.stortek.com>.

        * man: Included a shell script to automatically generate an
	  acewindex.html file.  This file is useful just after running
	  man2html.  Thanks to Vincent Pommier
	  <pommier@volnay.stortek.com> for contributing this.

        * man/html: I've just used the man2html programs to generate the
	  html documentation from the man3 directory.  It seems to work
	  pretty well.

	* ace/Assert.h: Added a forward declaration for class ACE_Log_Msg
	  to fix problems NuMega preprocessing.  Thanks to Mike Flinn
	  <mike.flinn@smtpgate.aws.waii.com> for finding this.

        * ace: Implemented about 1/3rd of the "dump" methods for the
	  various ACE classes.

	* ace/Acceptor.cpp (info): Fixed a bug -- should use PR_AD rather
	  than ACE_INET_Addr since this is used for SPIPEs as well...

	* ace/Synch_T.cpp (ACE_TSS): If ACE_Thread::keycreate () fails
	  then we do an fprintf() and return at the moment.  It doesn't do
	  any good to do an ACE_Log_Msg operation since those all require
	  thread-specific storage and this will just cause a recursive
	  problem...

	* ace/OS.cpp: Removed a memory leak in ACE_OS::thr_destory_tss()
	  that was caused by forgetting to delete each ACE_TSS_Key_Info
	  object when we no longer needed it.  Thanks to Mike Flinn
	  <mike.flinn@smtpgate.aws.waii.com> for finding this.

	* ace/OS.cpp: Added a new method to class ACE_OS called
	  thr_keyfree().  This enables us to free up a thread-specific
	  storage key on Win32 (it isn't implemented on the UNIX
	  platforms).

	* ace/ACE.cpp (timestamp): In order to get ACE_OS::timestamp to
	  work on Win32, the wMonth, wDay, wYear structure members were
	  added to the sprintf statement.  Thanks to Mike Flinn
	  <mike.flinn@smtpgate.aws.waii.com> for this fix.

	* examples: Changed all uses of ACE::send_n (1, ...) to
	  ACE_OS::write (ACE_STDOUT, ...) to avoid problems with NT's
	  hacked support for sockets and HANDLEs.  Thanks to Bernd Hofner
	  <hofner@pd.et-inf.uni-siegen.de> for noticing this.

Sun Mar 17 00:43:14 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/CORBA_Handler.cpp (handle_input): Fixed the CORBA_Handler to
	  use send()/recv() rather than read()/write().

	* ace/Process_Manager: put the hooks in for the forthcoming ACE
	  Process Manager, which will provide a service similar to the
	  ACE_Thread_Manager, except that it will work for processes, not
	  threads.

	* netsvcs: all the ACE network services appear to be working
	  again...

	* man: Completely regenerated all the manual pages to reflect all
	  the most recent changes.

	* ace/OS.h: Created a new macro called ACE_DEFAULT_REACTOR_SIZE.
	  This is useful for two reasons (1) it centralizes this value in
	  one place in ACE and (2) removes a horrible circular dependency
	  between the Service_Config.h and Reactor.h...

	* ace/Strategies: Added new strategies to handle "scheduling" of
	  Svc_Handlers launched by a Strategy_Acceptor.  In this context,
	  scheduling refers to "suspending" and "resuming" Svc_Handlers.
	  There are several alternative strategies ranging from (1)
	  suspending/resuming a single handler, (2) suspending/resuming
	  all the handlers in a Reactor, and (3) suspending/resuming all
	  handlers controlled by a Thread_Manager.  This very powerful
	  feature makes it simple to write ACE_Network_Services that can
	  control all their handlers in one fell swoop...

	* ace/Task: Added new accessors/mutators to get/set the
	  Thread_Manager and the Message_Queue associated with a Task.
	  This makes life easier and more abstract in subclasses and
	  elsewhere.

	* ace/Reactor: added an iterator to the ACE_Handler_Repository.
	  This makes it possible to implement the suspend_handlers() and
	  resume_handlers() very efficiently on both UNIX and Windows NT.

	* ace/Reactor: Added two new methods called suspend_handlers() and
	  resume_handlers().  These methods suspend and resume all the
	  active Event_Handlers in the Reactor in one fell swoop.

	* ace/Reactor.i (suspend_handler): Fixed a bug in the Reactor
	  where we were not factoring out the code for suspend_handler()
	  appropriately with respect to locking.

	* netsvcs/Logging/Server_Daemon/Thr_Logging_Handler: Enhanced the
	  threaded logging service so that all active threads can be
	  automatically suspended and resumed via the ACE_Service_Config
	  svc.conf file.

	* netsvcs/Logging/Server_Daemon/Logging_Handler.cpp: Rewrote the
	  ACE Logging service to use the new ACE_Strategy_Acceptor
	  implementation.  This greatly reduced duplicate code.  There's
	  almost nothing left in this directory save the actual service
	  itself!

	* netsvcs/Tokens: Rewrote the ACE Token service to use the new
	  ACE_Strategy_Acceptor implementation.  This greatly reduced
	  duplicate code.  There's almost nothing left in this directory
	  save the actual service itself!

	* netsvcs/Naming: Rewrote the ACE Naming service to use the new
	  ACE_Strategy_Acceptor implementation.  This greatly reduced
	  duplicate code.  There's almost nothing left in this directory
	  save the actual service itself!

Sat Mar 16 20:02:08 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* netsvcs: Created a new subdirectory off of $WRAPPER_ROOT and put
	  all the ACE network services (e.g., Time, Logging, Naming, and
	  Tokens) into that directory.  These services all instantiate the
	  new ACE_Strategy_Acceptor implementation, which greatly
	  simplifies their behavior and code.

	* ace/Acceptor: Made some enhancements to the
	  ACE_Strategy_Acceptor in order to make it more suitable for use
	  as a generic "Service" launcher.  This class now defines common
	  behavior for all the ACE network services (e.g., Time, Logging,
	  Naming, and Tokens).

	* apps/Token_Server: Made the main Token_Server application be
	  dynamically linked if there's a valid svc.conf file.

	* apps/Name_Server/Name_Server: Made the Server_Test a
	  "well-behaved" service.  Previously, it block in a private event
	  loop within Name_Server::run(), which was called by
	  Server_Test::init() when the service was linked dynamically.
	  This obviously doesn't work correctly since it means that we
	  can't dynamically link any other services after this one!  The
	  new version is "event-loop" friendly since it uses the main
	  Service_Config::run_event_loop() method.

	* ACE-categories: Added a new emacs "outline" file that
	  illustrates how the filenames in $WRAPPER_ROOT/ace cluster into
	  class categories.  Thanks to Chris Eich
	  <Chris_Eich@optilink.optilink.dsccc.com> and Alex V. Maclinovsky
	  <alexm@teltrunk1.tait.co.nz> for helping create this.

	* ace: Split ACE into two libraries: libACE and libACE_svcs.
	  libACE contains the "core" ACE components.  libACE_svcs contains
	  the client-side layered services (e.g., naming service, token
	  service, etc.).  There are two reasons for doing this:
	  
	  1. It reduces the size of ACE for many common usecases (i.e.,
	     most people aren't using the naming service or the token
	     service).  Any future layered services in ACE will be placed
	     into the libACE_svcs library rather than libACE.

          2. It works around annoying compiler bugs with lame compilers
	     like HP/UX C++.  Now, if those compiles can't compile the
	     token service (which is very template intensive) it won't
	     affect the core ACE library components.  This improves the
	     portability of ACE.

       * Added -lACE_svcs to the ./apps/{Token_Server,Name_Server} and
         ./examples/{Tokens,Naming} Makefiles to account for the new
         libraries.  Note that no source code changes are required...

Fri Mar 15 00:03:48 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* apps/Name_Server/server/Name_Handler.cpp (recv_request): Fixed
	  the same problem as occurred in Token_Handler (these both come
	  from the same source...).

	* apps/Token_Server/Token_Handler.cpp (recv_request): There was a
	  subtle bug in the Token_Handler that stems from my old code. 
	  The line

	  n = this->peer_.recv ((void *) (((char *) &this->token_request_)
					+ sizeof (ACE_UINT32)), 
				length);

	  This should actually be:

	  n = this->peer_.recv ((void *) (((char *) &this->token_request_)
		  			  + sizeof (ACE_UINT32)), 
			       length - sizeof (ACE_UINT32));

          since length was read already.  The old way tried to read 4
	  bytes too much.  Thanks to Jesper for noticing this.

	* ace/Connector.cpp (connect_svc_handler): Modified the connector
	  so that it automatically calls the close () method of the
	  Svc_Handler when the connection fails abortively.  This makes
	  the semantics the same for synchronous and asynchronous
	  connection invocation modes.  Thanks to Irfan for insisting on
	  this!

	* apps/Token_Server/Token_Acceptor.cpp (handle_input): Changed
	  return type from int to ACE_HANDLE for NT compatibility.  Thanks
	  to Jesper for this insight.

	* ace/OS.h: The defines for ACE_LACKS_MODE_MASKS (OS.h) were only defined
	  when !ACE_WIN32.  This has been fixed.  Thanks to Irfan for
	  spotting this too.

	* ace/OS.i (mmap): made a small change to ACE_OS::mmap to fix NT
	  portability problem (new variable added:nt_flags).  Thanks to
	  Irfan for spotting this.

	* ace/Local_Tokens.h: Added #include "ace/Map_Manager.h" after
	  line 41 in Local_Tokens.h to allow ACE to compile correctly with
	  the horrid HP/UX compiler.  Thanks to Neil Cohen for figuring
	  this out (what a trooper!).

	* ace/Local_Tokens.cpp (ACE_TPQ_Entry *): Replace

	  return ACE_TSS<ACE_TPQ_Entry>::operator ACE_TPQ_Entry *();

	  with

	  return  (ACE_TPQ_Entry *) (*((ACE_TSS<ACE_TPQ_Entry> *) this));

	  to work around problems with MSVC++ 4.0 when the browse option
	  is enabled.  Thanks to Kirk Sinnard <1764@mn.lawson.lawson.com>
	  for this fix.

	* ace/config-sunx86-sunc++-4.x.h: Swapped the lines

	  // Compiler/platform supports SVR4 signal typedef.
	  //#define ACE_HAS_SVR4_SIGNAL_T
	  #define ACE_HAS_CONSISTENT_SIGNAL_PROTOTYPES

	  to

	  // Compiler/platform supports SVR4 signal typedef.
	  #define ACE_HAS_SVR4_SIGNAL_T
	  //#define ACE_HAS_CONSISTENT_SIGNAL_PROTOTYPES

	  to avoid an error using ProWorks C++ 4.0.1 (w/ patches) which
	  blow up in the Signal.x stuff with a prototyping error.  Thanks
	  to John P. Hearn <hearn_j@sat.mot.com> for this recommendation.

	* ace/Shared_Memory.h: The conditional compilation wrapper was out
	  of date, so I renamed it.  Thanks to Alex V Maclinovsky
	  <alexm@teltrunk1.tait.co.nz> for reporting this.

Thu Mar 14 23:18:59 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Thread.h: There was a bug in the ACE_Thread class.  I
	  attempted to make the class uninstantiable by making the
	  constructor private.  However, the statement was:

	  private:
	  Thread (void);

	  which is not the definition of the ctor!  The code compiled
	  since it thinks Thread is a member function.  As a result, you
	  could instantiate a object of ACE_Thread class, but no longer...
	  Also added this to the !defined (ACE_HAS_THREADS) arm of the
	  conditional compilation.  Thank to Sandeep Joshi
	  <sandeepj@emailbox.att.com> for noticing this.

	* ace/Log_Record.i (decode): Fixed a stupid typo where htonl
	  (this->length_) should have been htohl (this->length_)...
	  Thanks to Audun Tornquist <Audun.Tornquist@iu.hioslo.no> for
	  noticing this.

Tue Mar 12 14:51:39 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Name_Request_Reply.cpp (decode): Added ntohl and htonl calls
	  wherever data was being exchanged.

Sat Mar  9 17:49:51 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* ace/OS.i (cond_wait): Updated the Win32 implementation to
          correspond precisely with the UNIX semantics where the mutex is
          always reacquired even when errors occur.

Mon Mar  4 23:03:37 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* INSTALL: updated the win32 to describe building test
	  applications.

Mon Mar  4 16:17:05 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Local_Name_Space.cpp (resolve): Fixed a small bug. The type
	  field in resolve was copying extraneous stuff (because of being
	  kept around as a wchar_t). So I added a new method to the class
	  ACE_NS_String called len() which simply returns len_. Using this
	  I can now do a strncpy of len bytes for type (instead of a
	  simple strcpy) and then null-terminate the string to remove the
	  garbage.

Thu Feb 29 23:41:04 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* ace/Token_Request_Reply.cpp: Fixed a byte-order bug which was
          showing up on intel platforms.

	* ace/Remote_Tokens.cpp: Fixed a race condition in
          ACE_TSS_Connection which was munging mt token server clients.

	* examples/Tokens/mutex/*: The Token Server example applications
	  now use ACE_Thread_Manager, which should make them portable to
	  Win32.

	* apps/Token_Server/Token_Server.cpp: The Token Server is now a
	  Service_Object which can be dynamically linked.

	* ace/OS.i: Win32 ACE_OS:: signal methods now return 0 instead of
	  -1.  So, calls to signal code succeed, but do nothing useful.

Thu Feb 29 20:38:32 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* apps/Logger/Server_Daemon/Server_Logger.cpp
	  (handle_logging_record): There was a typo where
	  ACE_LACKS_STATIC_DATA_MEMBER_TEMPLATES was incorrectly spelled.
	  This caused problems on HP/UX.  Thanks to Neil Cohen for
	  finding this.

Wed Feb 28 11:41:49 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * ace/Mem_Map.cpp: Fixed a nasty bug with Win32 memory mapping...
	  It turns out we need to be very careful when remapping a
	  previously mapped region if the MapViewOfFile we're trying to
	  establish *grows* beyond what was originally mapped with
	  CreateFileMapping().  The new scheme seems to work correctly
	  with both UNIX and Win32.

        * ace/OS.h: apparently when using MFC library functions it
	  is not possible to include windows.h.  Instead, users 
	  must include AFX.h.  Therefore, I've modified OS.h to 
	  include the following:

	  #if !defined (__AFX_H__)
	  #include <windows.h>
	  #endif /* __AFX_H__ */

	  Thanks to Patty Genualdi (genualdp@agcs.com) for pointing this
	  out.

	* ace/Memory_Pool.cpp: Modified init_acquire() so that it calls
	  ACE_Mem_Map::open() rather than ACE_Mem_Map::map() the first
	  time.  This ensures that the file is mapped correctly.

	* ace/Mem_Map: Added a new method called open() that creates/opens
	  a file without actually mapping it.

	* ace/SOCK_Dgram_Mcast.cpp (make_multicast_address): Added 
	  new support for Windows NT.

	* ace/Memory_Pool: reimplemented ACE_MMAP_Memory_Pool so that uses
	  ACE_Mem_Map.  This ensures that we can leverage all the work
	  that went into making ACE_Mem_Map work on Win32.

	* ace/Memory_Pool.cpp (map_file): Modified the code so that we
	  always unmap the file before trying to remap it.  This avoids
	  problems with Win32...

        * ace/Mem_Map: Modified the implementation of ACE_Mem_Map so that
	  it takes advantage of the improved features in ACE_OS::mmap.
	  Also added new a method that returns the memory-mapped addr more
	  easily.

        * ace/OS: Modified the ACE_OS::mmap() method so that it is more
	  efficient for remapping files on Win32.

	* ace/OS.h: renamed the type QWORD to ACE_QWORD to avoid namespace
	  pollution.  Thanks to Patty Genualdi (genualdp@agcs.com) for
	  pointing this out.

	* ace/OS.h: Changed the value of the SIGPIPE emulation for Win32
	  to match the UNIX value in order to avoid problems.  Thanks to
	  Jesper for noticing this.

	* apps/Token_Server: Fixed misuse of int for ACE_HANDLE in various
	  places.  Thanks to Jesper for noticing this.

        * Renamed the ./tests directory to ./examples to make way for the
	  new ACE regression tests.  These tests will go into the new
	  ./tests directory.

	* ace/Mem_Map.cpp: Added a destructor and a close() method that
	  closes down the file HANDLE if we allocated it.  This is useful
	  to prevent descriptor leaks.  Thanks to Irfan for suggesting
	  this.

        * ace: Made a number of changes to remove unreferenced parameters
	  from ACE methods.  This eliminates zillions of warning from the
	  HP/UX compiler.  Thanks to Neil Cohen for reporting this.

	* ace/Local_Name_Space.cpp (resolve): revised some code to work
	  around bugs with the HP/UX compiler...  Thanks to Neil Cohen for
	  this workaround.

Tue Feb 27 21:06:09 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * ace/OS.i: The Win32 CreateFile does not handle the return you
	  would expect when the file exists.  You would expect EEXISTS (17
	  in UNIX) but the GetLastError is set to 80
	  (ERROR_FILE_EXISTS).  Therefore, I changed ACE_OS::open to map
	  ERROR_FILE_EXISTS onto EEXIST.  This is only a partial solution,
	  however.  There must be a better way to handle this!

	* ace/Mem_Map.cpp (ACE_Mem_Map): Fixed a bug with one of the
	  ACE_Mem_Map destructors that was causing problems due to the
	  fact that base_addr_ wasn't being initialized to 0.  Thanks to
	  Karlheinz for noticing this.

        * ace/Signal.i: signals on AIX cannot use sigprocmask() in any
	  multithreaded programs.  Instead, the call
	  ACE_OS::thr_sigsetmask() should be used since it is used to
	  update the thread signal mask.  This comes up only in the
	  Sig_Guard constructor and destructor.  Therefore, I #ifdef the
	  call under the ACE_MT_SAFE macro, using sigprocmask() in the
	  #else case.  Thanks to Chris Lahey for reporting this.

        * tests: removed all uses of ACE_OS::join (0, ....) in ACE and
	  replaced them with ACE_Thread_Manager::wait() calls.  This
	  ensures that the ACE code is portable to Win32 and POSIX
	  pthreads! 

	* ace/Dynamic_Service.cpp: Added a #include of
	  "ace/Service_Config.h" to work around problems with HP/UX.
	  Thanks to John Morey for reporting this.

Sun Feb 25 12:10:38 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * apps/Token_Server: changed the name token_server.cpp to main.cpp
	  to avoid a name clash on Win32...

	* man/man3: updated all the ACE manual pages to reflect the
	  most recent changes.

        * ace/OS.i: Implemented the cond_timedwait() method correctly in
	  ACE_OS.  This method should now do the right thing with respect
	  to blocking, polling, and timewaits for Win32.

	* ace/OS.i: Modified the Win32 implementation of all the
	  socket-related wrappers in ACE_OS.  The new implementation very
	  cleverly sets errno to the result of WSAGetLastError() if a
	  socket-related call fails.  Since all of the WinSock errors are
	  mapped into their equivalent UNIX errno values this enables
	  socket applications to work portably for UNIX and Win32.	  

	* ace/Malloc_T.cpp (ACE_Malloc): Improved error reporting for
	  cases where the Memory_Pool::init_acquire() fails (e.g., if the
	  backing store was already created by another user and we don't
	  have permission to access it...).

        * ace/Task: modified Task.h so that it is no longer necessary to
	  write #include "ace/Synch_T.h" in order to use ACE_MT_SYNCH,
	  etc.

	* ace/SOCK.cpp (DllMain): Added a clever "Schwartz counter" to
	  make sure that the WinSock library is correctly initialized,
	  even if we're not using ACE as a DLL!!!

	* tests/Mem_Map/file-reverse: got the file reverse test program
	  working.  The ACE_Mem_Map class should now be ported to Win32...

	* ace/OS.i (open): Changed how the O_CREAT flag was handled
	  to give it UNIX semantics...

Sat Feb 24 12:55:27 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/UPIPE_Stream.cpp (recv): Fixed a signed/unsigned mismatch.
	  There should be no more mismatches in ACE...

	* ace/Name_Proxy.cpp (recv_reply): Fixed a signed/unsigned
	  mismatch.

	* ace/Message_Block.cpp (copy): Fixed a signed/unsigned mismatch.

	* ace/INET_Addr.cpp (get_host_name): Changed the type of the
	  hostnamelen parameter from int to size_t to be more "abstract."
	  This will also prevent a warning from the MSVC++ compiler.

	* apps/Logger/Client_Daemon/Client_Logger.i: Fixed a braino with
	  network byteoder that was causing Client_Logger::send() to fail
	  on INTEL boxes.  Thanks to Bryon G. Rigg
	  <bgrigg@opus.bcbnet.com> for finding this.

Fri Feb 23 01:59:34 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.i: Enhanced mmap() to give the same semantics as UNIX
	  mmap() by using MapViewOfFileEx().  Also greatly improved the
	  UNIX emulation capabilities so that mmap() now has the same API
	  for UNIX and Win32.

        * ace/Time_Value: Added functions to constructor and conversion
	  from/to Win32 FILETIME. This enables us to reuse those 100ns
	  conversions in ACE_Profile_Timer.

        * ace/Time_Value: Fixed a problem with these:

	  // True if tv1 < tv2.

	  INLINE int
	  operator < (const ACE_Time_Value &tv1, 
	              const ACE_Time_Value &tv2)
	  {
	    ACE_TRACE ("operator <");
	    return tv2 > tv1;
	  }

	  This should be "tv2 >= tv1".  Same problem was fixed with
          operator <=.

	* ace/Profile_Timer.i, fixed the following:

	  this->end_time_ = ACE_OS::gettimeofday ();
	  this->last_time_ = this->end_time_;
	  this->last_usage_ = this->end_usage_;
	  ACE_OS::getrusage (RUSAGE_SELF, &this->end_usage_);

	  This will overwrite end_time before it is saved to
	  last_time...

        * tests/Threads: Added Jesper's test for readers/writers locks.
	  The test adds a number of reader and writer threads.  When
	  active, writers modify a shared variable and verify that only
	  one writer and no readers are active.  When active, readers
	  check that no writers are active and that the shared data is
	  never changed.  The test passes for different ratios of
	  readers/writers, and debug output shows that several readers are
	  allowed simultaneously. Or, in other words, we have an
	  indication that it should work.

	* ace/OS.i: Added Win32 implementations of getpid(), fork(),
	  lseek(), dup(), cond_timedwait (), getrusage ()

	* ace/OS.i: Modified all the ACE_OS::str* routines so that they no
	  longer do an ACE_OSCALL_RETURN.  This can lead to weird bugs...
	  Thanks to Jesper for noticing this.

	* ace/config-sunos4-sun4.1.4.h: Added a new config file that
	  should work with SunOS 4.x...  Also added support for SunOS
	  4.1.4.  Thanks to Mick Adams (eeimas@eei.ericsson.se) for help
	  with this.

Thu Feb 22 18:58:36 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* tests/Naming/Client/Name_Service.h (ACE_Service_Object):
	  Modified test application to make use of ACE_Dynamic_Service.

	* ace/Dynamic_Service.h: Added a new class called Dynamic_Service
	  which provides a general interface to add and retrieve arbitrary
	  things into the ACE service repository.

	* apps/Name_Server/README: Rearranged files so that Name_Server
	  and Name_Handler are now contained in the server directory under
	  apps and are no longer under /ace. Also, the Dump_Restore
	  directory has been moved under /tests/Naming.

Thu Feb 22 01:56:46 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/INET_Addr.cpp (set): Fixed a byteorder bug in ACE_INET_Addr
	  that was causing problems when ACE was used on Win32 running on
	  Intel platforms...

	* ace/Mem_Map.cpp (map_it): Fixed ACE_Mem_Map so that it will work
	  correctly on Win32.

	* ace/SOCK_Stream.i: Changed the implementation of the Win32
	  versions of send() and recv() so that they will never use the
	  read() and write() calls.  This works around limitations with
	  Win32, which can't do a ReadFile() or WriteFile()
	  *synchronously* with a SOCKET.

	* Changed all occurrences of read (0, ...) to read (ACE_STDIN,
	  ...)  and all occurrences of write (1, ...) to write
	  (ACE_STDOUT, ...) in order to be compatible across UNIX and
	  Win32.

	* tests/ASX/Event_Server: Fixed up all the socket I/O calls so
	  that they use the WinSock send()/recv() methods rather than
	  ReadFile and WriteFile...

	* ace/OS.i: Updated open() to correctly emulated UNIX open()
	  semantics on Win32.

	* ace/OS.cpp (thr_exit): Added support to the NT port so that
	  thr_exit() doesn't endup doing multiple deletions of the same
	  object.  Thanks to Karlheinz for this fix.

	* ace/OS.h: Moved the location of ACE_MAXCLIENTIDLEN so that
	  MAXHOSTNAMELEN would be correctly visible for NT.

	* ace/Reactor.cpp: Added a temporary fix for the fact that
	  writev() and readv() don't work correctly yet on NT.  The
	  solution is to replace write() with two writes() and readv()
	  with two reads() for the Reactor's notification scheme.  A
	  better solution should be forthcoming.

	* ace/Reactor.cpp: Made sure to initialize the timer_queue_ to 0
	  in the constructors so that the Reactor's destructor can avoid
	  crashing horribly if the constructor fails.  Thanks to Karlheinz
	  for pointing out the need for this.

	* ace/SOCK.cpp: Added support for WSAStartup for using WinSock
	  within the ACE_SOCK class.

Wed Feb 21 21:05:55 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/ACE.cpp (bind_port): Made a quick fix to work around the
	  fact that NT doesn't set errno...

	* ace/OS.i (mmap): Fixed a bug in mmap for the NT port.  It should 
	  return MAP_FAILED on error rather than 0 to be equivalent to the
	  UNIX version.  Thanks to Irfan for spotting this.

Mon Feb 19 00:31:42 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Typed_SV_Message.i (ACE_Typed_SV_Message): Modified the
	  constructor calls so that length_ and max_size_ are correctly
	  set when created.  Thanks to Alexandre Karev
	  <akg@na47sun05.cern.ch> for reporting this.

	* ace/SV_Message_Queue.i (remove): fixed bug in
	   ACE_SV_Message_Queue::remove method where `internal_id_' member
	   was modified *BEFORE* it was used the last time in
	   ACE_SV_Message_Queue::control.  Thanks to Alexandre Karev
	   <akg@na47sun05.cern.ch> for reporting this.

	* ace/Typed_SV_Message.i (length): Fixed a minor typo that caused
	  a bigger bug ;-).  Thanks to Alexandre Karev
	  <akg@na47sun05.cern.ch> for reporting this.

	* ace/OS.h: Added new macros that allow programs to portably
	  access stdin, stdout, and stderr HANDLEs on Win32 and UNIX as
	  follows:

	  #if defined (ACE_WIN32)
	  #define ACE_STDIN GetStdHandle (STD_INPUT_HANDLE)
	  #define ACE_STDOUT GetStdHandle (STD_OUTPUT_HANDLE)
	  #define ACE_STDERR GetStdHandle (STD_ERROR_HANDLE)
	  #else
	  #define ACE_STDIN 0
	  #define ACE_STDOUT 1
	  #define ACE_STDERR 2
	  #endif /* ACE_WIN32 */

	* ace/INET_Addr.i: modified the return value of get_port_number so
	  that it returns the value in host byte order.  This has actually
	  been a latent bug in ACE for years, but it only surfaced
	  recently after porting to NT on the Intel instruction set (which
	  is "little-endian").

	* tests/ASX/Event_Server: Merged in the latest changes to the
	  Event_Server tests, which enable it to compile on Windows NT.
	  Now, I just need to get it working on NT...

        * Updated all of ACE to use the new ACE_ASSERT rather than assert.

	* ace/Assert.h: Added a new file and a new macro called
	  ACE_ASSERT.  This uses the ACE_Log_Msg Singleton to provide a
	  more consistent means to do assertions.  Thanks to Alexandre
	  Karev <akg@na47sun05.cern.ch> for suggesting this.

	* ace/Log_Msg.cpp (log): added for method ACE_Log_Msg::log lines
	  to skip the `sprintf' part for %N - file name and %l - line
	  number format specifiers.  Thanks to Alexandre Karev
	  <akg@na47sun05.cern.ch> for reporting this.

        * Remote_Name_Space: Removed an initalizer to ACE_WString that was
	  driving the HP/UX compiler nuts.

Sun Feb 18 18:11:22 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Synch.h (ACE_Null_Condition_Mutex): Added a missing body to
	  the wait() method.  Thanks to Byron Riggs for noticing this.

Sat Feb 17 19:10:06 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

        * tests/Naming/README (client): Added description for new
          features, including support for list_values and list_types. Also
          added a small description about test programs using DLL.

        * ace/Name_Request_Reply.cpp (decode): Fixed a small bug in
          ACE_Name_Request::decode. type_ was not null terminated causing
          some garbage to be returned.

Thu Feb 15 14:57:06 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

        * ace/Remote_Name_Space.cpp: Changed names of some parameters to
          comply with ACE syntax.

Wed Feb 14 13:36:31 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

        * ace/Local_Name_Space.cpp (resolve): Type support has been added
          to Name_Server. A new class called ACE_NS_Internal was created to
          keep value and type information.

Fri Feb  9 17:12:00 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* "Officially" released ACE 4.0

	* ace/OS.i (sema_post): Fixed a bug in the NT port.

  		#elif defined (ACE_HAS_WTHREADS)
		  return ::ReleaseSemaphore (*s, 1, 0);
		#endif /* ACE_HAS_STHREADS */

          This returns 1 for success, and disturbs cond_broadcast...
	  This was replaced by:

		#elif defined (ACE_HAS_WTHREADS)
		  return ::ReleaseSemaphore (*s, 1, 0) ? 0 : -1;
		#endif /* ACE_HAS_STHREADS */

	  Thanks to Jesper S. M|ller  (stophph@diku.dk) for this.

	* ace/OS.i (cond_init): Fixed a bug in the NT condition synch
	  code, as the initial count of the semaphore was 1. This gives an
	  inconsistent condition: The first waiter went straight through...
	  Change in ACE_OS::cond_init:

		if (ACE_OS::sema_init (&cv->sema_, 0, type, name, arg) != 0)
		  return -1;

	  Thanks to Jesper S. M|ller  (stophph@diku.dk) for this.

	* ace/Singleton.cpp: Fixed a stupid bug that was caused by failure
	  to #include "ace/Synch_T.h"...  Thanks to Neil Cohen and Byron
	  Riggs for giving me insights on what the problem was.  ACE now
	  compiles on HP/UX.

Fri Feb  9 11:07:04 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* tests/Naming/server/Server_Test.cpp (init): Modified server
	  tests to dynamically link Naming Services.  Both client and
	  server tests now make use of the ACE dynamic linking mechanisms.

	* ace/Local_Name_Space.cpp: Added list_values() to Name
          Server. The functionality is very similar to list_names (returns
          list of values that match a pattern).

	* tests/Naming/client/Client_Test.cpp (bind): Replaced all uses of
	  cerr and cout with ACE_ERROR, ACE_ERROR_RETURN, and ACE_DEBUG.
	  Split the file Client_Test.cpp into two files -- Client_Test.cpp
	  and Name_Service.cpp (similarly .h file) each containing the
	  corresponding class. Modified svc.conf to work with the changes.

Thu Feb  8 02:05:26 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Log_Msg.cpp (log): Enhanced the Log_Msg class so that it
	  supports "nested" calls via %r.  If SILENT mode enabled, nested
	  outputs will enclosed in {..} brackets in thread-specific
	  storage.  Thanks to Alexandre Karev <akg@na47sun05.cern.ch> for
	  suggesting this.

	* ace/Synch: Added a new class called ACE_Null_Condition_Mutex.
	  This is necessary to fix bugs with stupid compilers...  Thanks
	  to Zusman Mark <marklz@rotem.technion.ac.il> for reporting this.

	* tests/Naming/client: made a first pass implementation of a
	  client application that dynamically links in a Naming_Context
	  based on information provided by the svc.conf file.

	* ace/Name_Options: Fixed yet more problems with dynamic memory
	  management.  The old version didn't make a copy of the strings
	  it was passed and this caused major problems.

	* ace: Fixed a whole slew of problems with the ACE Name Server
	  stuff that arose from inconsistent use of const char * vs.  char
	  *...

Wed Feb  7 00:58:45 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/CORBA_Handler.cpp (ACE_MT_CORBA_Handler): Added new
	  enhancements to ACE_MT_CORBA_Handler to make it work correctly
	  with Windows NT.  Thanks to Irfan for making these changes.

	* ace/Connector.cpp (fini): Make another workaround for bugs with
	  MSVC++ 2.0...

	* ace/SPIPE_Connector.cpp (connect): Added a call to ACE_CLR_BITS
	  (flags, O_CREAT) to make darn sure that the O_CREAT flag is not
	  set.  Thanks to Chris Cleeland for suggesting this.

Tue Feb  6 01:40:29 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.h: added a new prototype to OS.h that should help with
	  portability to nasty platforms with broken rand_r() definitions.
	  Thanks to Aurelio Nocerino
	  <aurelio@irsipcs2-27-le0.irsip.na.cnr.it> for suggesting this.

	* Local_Tokens: Changed all uses of enumerals MAXTOKENNAMELEN and
	  MAXCLIENTIDLEN to symbol #defines ACE_MAXTOKENNAMELEN and
	  ACE_MAXCLIENTIDLEN.  This works around bugs with HP/UX.
	  Thanks to Neil Cohen for reporting this problem.

	* ChangeLog: split the ChangeLog files into 4 separate files --
	  one for '96, '95, '94', and '93.  Hard to believe I've been
	  working on this stuff for so long!

	* ace/OS: Fixed the use of ::memset to replace sizeof buffer with
	  sizeof (ACE_SERVENT_DATA) and sizeof (ACE_HOSTENT_DATA).  This
	  fixes bugs that surfaced on AIX.  Thanks to Chris Lahey for
	  finding these.

	* ace/SPIPE_Addr.cpp (ACE_SPIPE_Addr): Fixed a bug in
	  SPIPE_Addr::SPIPE_Addr(const SPIPE_Addr&).  What happens is that
	  when the size is calculated it does not take into account the
	  required zero byte at the end of the rendezvous_ member.  Thanks
	  to Chris Cleeland <chris@envision.com> for reporting this.

	* ace/Local_Tokens: Had to move all ACE_Token_Proxy methods from
	  Local_Tokens.i to Local_Tokens.cpp and remove INLINE - otherwise
	  gcc reported them as undefined methods during linkage stage.
	  Thanks to Zusman Mark <marklz@rotem.technion.ac.il> for
	  reporting this.

	* ace: Changed ACE_Name_Request_Reply::LAST to
	  ACE_Name_Request_Reply::MAX_ENUM to avoid problems with name
	  conflicts on OSF/1.  Thanks to Eshel Liran
	  <liran@bimacs.cs.biu.ac.il> for suggesting this.

	* ace/Synch_T: Fix all definitions of ACE_Atomic_Ops so that they
	  compile correctly on platforms that lack threads!  Thanks to
	  Alexandre Karev <akg@na47sun05.cern.ch> for noticing this.

	* include/makeinclude: Added a new config file from Bryon G. Rigg
	  <bgrigg@opus.bcbnet.com>, which should allow ACE to build on
	  Linux.

	* ace/Remote_Tokens.cpp: Moved ACE_TSS_Connection to
	  Remote_Tokens.h to avoid problems with AIX.  Thanks to the
	  ever-vigilant Chris Lahey for reporting this.

Mon Feb  5 23:34:42 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* Added CORBA_Ref.h which contains the new class ACE_CORBA_Ref.
	  This class provides a nice wrapper for making the use of Orbix
	  object references more transparent.  This is done by automating
	  the release and duplicate calls.

Mon Feb  5 15:43:17 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace: added Prashant's latest changes to the Name_Handler*,
	  Naming_Context*, and Remote_Name_Space*.  These changes make it
	  possible to retrieve lists of values based on a pattern, which
	  can be a regular expression.

	* Moved the apps/Name_Server/Client-Server tests into tests/Naming
	  and most of the apps/Token_Server/* tests into tests/Tokens to
	  conform to Karlheinz's testing style.

	* ace: Modified a number of files in ACE to make it compile
	  correctly with MSVC++ 2.0.

Sun Feb  4 23:58:43 1996  Douglas C. Schmidt  (schmidt@mambo.cs.wustl.edu)

	* ace/Reactor: Generalized ACE_Null_Callback to work correctly
	  with Windows NT (which lacks pipes).  The new design uses the
	  ACE socket wrappers for NT.  It requires very few changes to the
	  code to handle NT now!  Also changed the name to
	  ACE_Notification_Handler, which is more descriptive.

Sun Feb  4 14:47:50 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Remote_Tokens.cpp: Reworked ACE_Singleton to avoid
	  portability problems on compilers like GCC.

Thu Feb  1 12:47:46 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Remote_Tokens.cpp: Generalized the parameters passed into
	  ACE_Singleton so they would compile on HP/UX and other platforms
	  that lack threads.  Thanks to Neil Cohen for noticing the
	  problem.

Wed Jan 31 22:49:13 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace: Modified a number of minor things in ACE to get it to
	  compile successfully with Windows NT MSVC++ 4.0.  Updated the
	  INSTALL file to explain this process better...

Tue Jan 30 01:12:07 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/CORBA_Handler.cpp: changed things so that no diagonistic
	  messages are printed.

	* Regenerated all the ACE manual pages to bring them up to date
	  with the recent changes.

	* ace/Malloc.h: Modified the ACE_Malloc header file so that it
	  works correctly when ACE_MALLOC_STATS is enabled.  Thanks to
	  Alexandre Karev <akg@na47sun05.cern.ch> for reporting this.

	* ace/OS.cpp (mutex_lock_cleanup): removed the leading & before
	  p_lock.  Thanks to Chris Lahey for noticing this.

	* ace: Added the new ACE_Singleton class.  This class uses the
	  Adapter pattern to turn ordinary classes into Singletons
	  optimized with the Double-Check pattern.

	* Added Tim's latest Token Server changes (which include support
	  for local and remote mutexes and readers/writer locks) and
	  Prashant's latest Name Server changes (which allows the contents
	  of a Name Server to be dumped and restored to/from an ASCII
	  file).

Mon Jan 29 02:22:23 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Handle_Set: Changed MAX_SIZE and WORD_SIZE to MAXSIZE and
	  WORDSIZE to avoid name collisions with HP/UX.  Thanks to Byron
	  Rigg <bryon_rigg@mail.telecorpsys.com> for suggesting this.

	* ace/Time_Value.h: Added a new config symbol ACE_HAS_SVR4_TIME to
	  differentiate between UNIX platforms that support "POSIX_TIME"
	  (i.e., timespec_t) and those that support "SVR4_TIME" (i.e.,
	  timestruc_t).  This is necessary to work around HP/UX...  Thanks
	  to Byron Rigg <bryon_rigg@mail.telecorpsys.com> for suggesting
	  this.

	* ace/config-hpux-10.x.h: config-hpux.h has now been renamed to
	  config-hpux-10.x.h and config-hpux-9.x.h.  Thanks to Byron Rigg
	  <bryon_rigg@mail.telecorpsys.com> for suggesting this.

	* ace/Synch_T: Added a new method called ts_get() and made both
	  the operator-> and operator TYPE * call this.  I hope this will
	  fix a bug with HP/UX reported by Neil Cohen...

	* ace/OS.i (dlclose): Added Win32 support for dlclose().  Thanks
	  to Todd L. Montgomery <tmont@cerc.wvu.edu> for pointing the way
	  here...

	* ace: Split off the old class ACE_Dynamically_Allocated, renamed
	  it ACE_Dynamic, put it in a separate file called Dynamic.*.
	  This is necessary to solve nasty multiple definition problems
	  with compilers that require the source of template.

	* ace/Synch_T: moved

	  template <class TYPE> TYPE *
	  ACE_TSS<TYPE>::make_TSS_TYPE (void) const
	  {
	    return new TYPE;
	  }

	  out from condition compilation block

	  #if (defined (ACE_HAS_THREADS) && defined(ACE_HAS_THREAD_SPECIFIC_STORAGE))

	  in file Synch_T.cpp.  This class member called in many other
	  places regardless ACE_HAS_THREADS and
	  ACE_HAS_THREAD_SPECIFIC_STORAGE defined or not...

	* ace/Name_Handler.cpp: Changed the use of the "inherited" typedef
	  to fully expand to ACE_Svc_Handler<ACE_SOCK_STREAM,
	  ACE_NULL_SYNCH>.  This is necessary to workaround bugs with AIX.
	  Thanks to Chris Lahey for reporting this.

	* tests and apps: Fixed an odd problem that only surfaced recently
	  with GNU G++.  Apparently, it doesn't like function-style casts
	  of the form ACE_SignalHandler (foo), but will accept
	  (ACE_SignalHandler) foo.  Since both approaches are equally good
	  for what I'm doing, I've updated all the code in ACE to be more
          portable.

Sun Jan 28 12:24:58 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* tests/Shared_Malloc/test_malloc.cpp (spawn): 	when forming
	  argv[] for execv, moved 

	  argv[ ... ] =  Options::instance ()->debug () ? "-d" : "";

	  to the end of the vector just before terminator.  This will
	  allow to pass rest of arguments to exec if -d switch not
	  specified.  Thanks to Alexandre Karev <akg@na47sun05.cern.ch>
	  for reporting this.

	* tests/Shared_Malloc/Malloc.cpp: To avoid conflict with
	  ACE_DEFAULT_SEM_KEY in OS.h changed SEMA_KEY value in
	  tests/Shared_Malloc/Malloc.cpp to ACE_DEFAULT_SEM_KEY + 1.
	  Thanks to Alexandre Karev <akg@na47sun05.cern.ch> for reporting
	  this.

	* ace/SV_Semaphore_Complex.i: Changed all arguments in calls like 
	
		this->acquire( n+2 )
	  and
		this->tryacquire( n+2 )
	  to
		this->acquire( n )
	  and
		this->tryacquire( n )
	.
	  Since the semaphore number is incremented by 2 in
		SV_Semaphore_Complex::acquire
	  and
		SV_Semaphore_Complex::tryacquire

	  when SV_Semaphore_Simple::(acquire/tryacquire) is called.
	  Thanks to Alexandre Karev <akg@na47sun05.cern.ch> for pointing
	  this out.

Sat Jan 27 16:14:27 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Read_Buffer: Added a new component that efficiently reads in
	  an artibrarily large buffer from a file up to an including a
	  termination character.  Also performs search/replace on single
	  occurrences a character in the buffer using the priniciples of
	  Integrated Layer Processing.

Fri Jan 26 12:01:06 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Thread_Manager: Made a small change to workaround the use of
	  a struct type for thread_t and hthread_t in HP/UX.  Thanks to
	  Bryon Rigg <bryon_rigg@mail.telecorpsys.com> for noticing this.

Thu Jan 25 19:54:01 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Svc_Handler: Added some minor changes to account for
	  limitations with GNU G++.  I think the new implementation will
	  be portable across all C++ platforms.

	* ace/SV_Semaphore_*: Widened the interface of SV_Semaphore*
	  classes to include a flags parameter.  This can be used to pass
	  in SEM_UNDO, which is important in many applications.  Thanks to
	  Andrew Gilbert <agilbert@csci.csc.com> for suggesting this.

	* ace/Synch_T.cpp: We are forced to "cast away const" inside of of
	  the ACE_TSS const methods in order to make the ACE_Guard work.
	  The right thing to do would be to make the lock "mutable" but
	  that's hopelessly non-portable.

Thu Jan 25 14:34:12 1996  Douglas C. Schmidt  (schmidt@merengue.cs.wustl.edu)

	* ace/Log_Msg: Fixed a minor bug in ACE_Log_Msg that kept
	  resetting the restart and iostream value no matter what we'd set
	  it to before.  Thanks to Prashant for finding this.

	* bin: Fixed up the Makefile process for the clone program.  Now
	  it builds without having to depend on ACE.  Thanks to Brad Brown
	  (bbrown@rdxsunhost.aud.alcatel.com) for suggesting this.

	* ace/Synch: Modified ACE_Condition*.remove so that cond_destroy()
	  is called in a loop if the condition variable is BUSY.  This
	  avoids a condition where a condition is signaled and because of
	  some timing problem, the thread that is to be signaled has
	  called the cond_wait routine after the signal call.  Since the
	  condition signal is not queued in any way, deadlock occurs
	  unless this loop is used.  Thanks to Chris Lahey for pointing
	  this out.

	* ace/CORBA_Handler: Made all the methods in ACE_CORBA_Handler
	  private to make sure that users don't inherit from this class!
	  Instead, the ACE_MT_CORBA_HAndler and ACE_ST_CORBA_Handler
	  should be used as Singletons.

	* ace/CORBA_Handler: Added new support for Orbix on Windows
	  NT.  This requires clever use of macros in order to handle
	  inherent differences between generated code. 

	* ace/Svc_Handler: Added a clever idiom that transparently checks
	  if we were allocated dynamically.  This information is used by
	  the <destroy> method to decide if we need to delete <this>...
	  The idiom is based on a paper by Michael van Rooyen
	  (mrooyen@cellnet.co.uk) that appeared in the April '96 issue of
	  the C++ Report.  We've spruced it up to work correctly in
	  multi-threaded programs by using our ACE_TSS class.

	* ace/config-win32-msvc4.0.h (ACE_LACKS_RECVMSG): Fixed a typo
	  in the MSVC++ config files.

Thu Jan 25 02:59:22 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Finally got the frigging library built on SGI.  This was a chore
	  due to compiler bugs, but at least it's another datapoint for
	  successful cross-platform building...

Wed Jan 24 00:10:29 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Time_Value.cpp (operator-=): Changed operator += and
	  operator -= to use const ACE_Time_Value & rather than
	  ACE_Time_Value &.  Thanks to Alex V Maclinvosky for noticing
	  this.  In addition, also changed *all* ACE_Time_Value parameters
	  to be const ACE_Time_Value &.  This should reduce the number of
	  excess constructors called...

	* ace/OS: Added Chris Lahey's latest changes that introduce POSIX
	  pthread cancellation cleanup handlers.  Also added an herror()
	  function that is comparable to perror().

	* ace/OS: (thr_join): Added a new version of thr_join() which
	  works for Windows NT.  Windows NT requires a HANDLE, which is
	  fundamentally incompatible with other things...

	* ace/Thread_Manager: added two new methods that return the
	  ACE_Thread_Descriptor corresponding to either a thr_id or a
	  thr_handle.

	* ace/Thread_Manager: Made the spawn() interface compatible with
	  the other spawn() interfaces in ACE_OS and ACE_Thread by adding
	  the hthread_t type.

	* ace/Log_Msg.cpp (log): Fixed things up so that we can now print
	  out the thread id for all versions of threads!

	* ace/OS: Added a new overloaded version of ACE_OS::thr_self()
	  that returns the "kernel" thread id.  This is necessary on
	  systems like NT and AIX, which separate kernel thread ids from
	  user thread ids.  Thanks to Chris Lahey for suggesting this.

Tue Jan 23 01:17:23 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.i (sigwait): Changed the parameter of sigwait() from
	  const sigset * to sigset *.  Thanks to Neil Cohen for chasing
	  this down on SunOS 5.5....

	* ace/Malloc_T.cpp: Fixed a typo in bind() whereby 
	  the test if (duplicates == 0 || this->shared_find (name) != 0)
	  should be if (duplicates == 0 && this->shared_find (name) != 0).
	  Thanks to the ever vigilant Alexandre Karev
	  <akg@na47sun05.cern.ch> for reporting this.

	* tests: Fixed all test programs that previously used the "execl"
	  family of system calls to use the "execv" family instead.

	* ace/OS: Added support for the "execv" family of exec() system
	  calls.  Unlike the "execl" family, these calls are easy to
	  support since they don't require variadic arguments.  I've added
	  the hooks for the "execl" family, as well, but haven't actually
	  implemented them yet.

	* ace/Memory_Pool.cpp (ACE_Shared_Memory_Pool): Fixed a bug that
	  was tickled when pool_name == 0.  Thanks to Alexandre Karev
	  <akg@na47sun05.cern.ch> for reporting this.

	* ace/OS.h: removed FD_SETSIZE from the ACE_WIN32 stuff since this
	  is defined in winsock.h.

	* ace/OS.cpp (ACE_Spawn_Args): Added "f" to the parameter list.

	* ace/CORBA_Handler: Added a new macro called CORBA_T that masks
	  the incompatibilities between the version of Orbix on NT and on
	  Solaris.  

	* ace/OS.h: Added support for compilers (like NT) that don't
	  support "mode masks" (these are used to give symbolic names for
	  file creation modes passed to open() and creat().

	* ace/SString.cpp: Added Tim's new copy constructor code for
	  SString.cpp.  This doesn't appear to be strictly necessary , but
	  it is more explicit and therefore it useful.

	* ace/Map_Manager.cpp: Fixed a bug in Map_Manager that was failing
	  to call the placement new operator for every element in the map
	  that was dynamically created by the allocator().

	* ace/Synch_T: Added Tim's new ACE_TSS implementation.  This
	  version is more flexible than the old one.

Mon Jan 22 00:03:24 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Time_Value.h: changed a few minor things to get this
	  compiling again on NT.  Thanks to Irfan for helping with this.

	* ace/Synch_Options: Changed all the "accessor" methods to be
	  const member functions at the request of Irfan.  I just know
	  this is going to cause const cancer... ;-)

	* ace/Acceptor and Connector: Changed all parameters that take
	  ACE_Synch_Options & to take const ACE_Synch_Options & at the
	  request of Irfan.

	* ace/OS.i (uname): Added rudimentary support for the uname()
	  function for Windows NT.  If anyone has suggestions on how to
	  fill in all these fields portably please let me know!

	* ace/Connector.h: Changed a stray -1 to ACE_INVALID_HANDLE.
	  Thanks to Irfan for noticing this.

	* ace/Profile_Timer.h: Added the keyword "public" to handle one
	  arm of the conditional compilation that is only exercised on
	  NT...  Thanks to Irfan for noticing this.

	* ace/OS.i (mutex_init): Removed the call to
	  pthread_mutexattr_setkind_np() it isn't in the final POSIX
	  standard.

	* ace/Reactor.cpp (unbind): Removed the ACE_MAX3 template function
	  from OS.h and inlined its only use in the Reactor.  This was
	  causing problems with some C++ compilers.  Thanks to Mark Zusman
	  <marklz@topaz.technion.ac.il> for reporting this.

	* ace/OS.i: Fixed a number of omitted return results in
	  gettimeofday() and ctime_r() that were masked by the
	  ACE_OSCALL_RETURN macros.  Thanks to Mark Zusman
	  <marklz@topaz.technion.ac.il> for reporting these.

	* ace/config-linux.h: Added new symbolic constants to handle the
	  fact that Linux seems to lack recvmsg(), sendmsg(), msync(), and
	  madvise().  Thanks to Neil Cohen for noticing this.

        * include/makeinclude: Fixed all the *-orbix.GNU files to use
	  $(ORBIX_ROOT)/lib rather than $(ORBIX_ROOT)/ace.  Thanks to
	  Pramod Kumar Singh <pramod@saturn.miel.mot.com> for reporting
	  this.

	* ace/config*.h: Changed all typos of the form ACE_HAS_SVSV_IPC to
	  ACE_HAS_SYSV_IPC.  Thanks to Alexandre Karev
	  <akg@na47sun05.cern.ch> for reporting this!

	* ace/OS: Changed the order of parameters passed to thr_create()
	  to be consistent with all the spawn() and spawn_n() usages in
	  ACE.  Thanks to Chris Lahey for pointing this out.

Sun Jan 21 15:06:15 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace: Added a new "priority" parameter to the spawn() and
	  spawn_n() methods in ACE_Thread and ACE_Thread_Manager.  This
	  allows us to pass the priority on down to thr_create().  Thanks
	  to Chris Lahey for pointing this out.  Note that this change
	  required reordering the parameters so that the stack and
	  stack_size parameters now come last for these methods.  Since
	  those are not likely to change much this is a good place to put
	  them (i.e., at the end).

	* ace/Thread.i (spawn_n): Added a new overloaded spawn_n() method
	  that accepts an array of thread_t's to be filled in.  This is
	  useful if you want to know the thread IDs of any threads
	  created.

	* Changed ACE_OS::signal() to ACE_Sig_Action across all of ACE to
	  be portable to pthreads implementations.  Thanks to Chris Lahey
	  for pointing this out.

	* ace/OS: Added a new set of OS C++ wrappers for POSIX pthread
	  cancellation routines.  Thanks to Chris Lahey for these.

	* ace/Thread: Added a new set of ACE C++ wrappers for POSIX
	  pthread cancellation routines.  Thanks to Chris Lahey for
	  these.

	* ace/Map_Manager: Revised the Map_Manager::bind method.  This has
	  now been split into bind() and rebind() methods.  The bind()
	  method is very simple -- if you try to bind() to something that
	  already exists you fail.  The rebind() method allows you to
	  atomically update existing values in a map.  It also gives you
	  back the existing values so that you can delete them if
	  necessary.  The Local_Name_Space::bind() and rebind() methods
	  have been updated to use this new interface.

	* ace/Malloc_T.cpp (find): Fixed a typo -- find() should have set
	  its pointer parameter to node->pointer_, rather than
	  node->name_!  This bug was revealed during testing of the ACE
	  Name Server.

	* ace/Local_Name_Space.cpp: Fixed bugs with computation of the
	  size of ACE_NS_Strings -- they needed to count the wchar_t's
	  correctly, along with several other minor fixes.  These were
	  revealed during testing of the ACE Name Server.

	* ace/SString.cpp: Fixed several bugs that prevented the
	  assignment operators from working correctly.  These were
	  revealed during testing of the ACE Name Server.

Sat Jan 20 08:33:54 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Local_Name_Space.cpp (shared_bind): The args to to the
	  NS_String constructors were not in the correct order:

	  wchar_t *value_rep = (wchar_t *) (ptr);
	  wchar_t *name_rep = (wchar_t *) (ptr + name_len);
	  ACE_NS_String ext_id (name.fast_rep (), name_rep, name_len);
	  ACE_NS_String int_id (value.fast_rep (), value_rep, value_len);

	  They should be:

	  ACE_NS_String ext_id (name_rep, name.fast_rep (), name_len);
	  ACE_NS_String int_id (value_rep, value.fast_rep (), value_len);

	  Thanks to Irfan for noticing this.

	* ace/OS.h: defined the following in ACE_OS:
 
          #define MS_ASYNC 0    
	  #define MS_SYNC 0    
	  #define MS_INVALIDATE 0    
 
          under NT so that calls to mmap will port transparently.  Thanks
	  to Irfan for suggesting this.

Thu Jan 18 16:25:16 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace: Added a new symbol that indicates if the platform supports
	  the new BSD sin_len field of inet_addr.

	* ace/OS: added new support for AIX gethostbyaddr_r(),
	  gethostbyname_r(), and getservbyname_r().  This fixes some
	  problems caused by improper choice of buffer size.  Also changed
	  the INET_Addr.cpp file to use these new changes.  Thanks to
	  Chris Lahey for recommending these changes.

Wed Jan 17 01:10:48 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.i (printf): the ACE_OS::printf() function did not work.
	  Needed to call vprintf() internally, not printf.  Thanks to
	  Chris Lahey for pointing this out.

	* Released version 4.0.  

	* include/makeinclude: added the -lgen library to all the
	  platform_sunos5.*.GNU files.

	* ace/Memory_Pool.cpp: removed the INLINE macros in Memory_Pool.cpp.
	  Thanks to Alexandre Karev (karev@vxcern.cern.ch) for noticing
	  this!

        * ace/Malloc_T.cpp: moved the comment "Ce n'est pas une catst"
	  outside of the macro ACE_NEW_RETURN.  The prepocessor truncates
	  the macro expansion when it encounters the comment.  Thanks to
	  Greg Baker <GBaker@p01.az15m.iac.honeywell.com> for pointing
	  this out.

	* ace/Reactor.cpp (close): added "return 0" at the end of the
	  close member function.  The function is prototyped to return an
	  int and the compiler expects a return outside of the if clause.
	  Thanks to Greg Baker <GBaker@p01.az15m.iac.honeywell.com> for
	  pointing this out.

	* ace/Stack.cpp (free_all_nodes): Removed a spurious ACE_OS that
	  was stuck on the front of ::delete.  Thanks to Greg Baker
	  <GBaker@p01.az15m.iac.honeywell.com> for pointing this out.

	* ace/OS.i: Added extern "C" to the prototype for syscall in OS.i.
	  Without it, you get unresolved symbols at link time.  Thanks to
	  Greg Baker <GBaker@p01.az15m.iac.honeywell.com> for pointing
	  this out.

	* ace/Message_Queue.cpp: Changed the return values for
	  enqueue_head(), enqueue_tail(), dequeue_head(), and
	  peek_dequeue_head() to return the number of messages that are
	  still on the queue.  This helps some algorithms perform better
	  and avoid blocking unnecessarily.  Thanks to Alex V Maclinvosky
	  <alexm@teltrunk1.tait.co.nz> for suggesting this...

	* ace/Synch_T.cpp (ACE_Condition): Fixed a bug in
	  ~ACE_Recursive_Lock and ~ACE_Recursive_Mutex that was causing
	  the destructor to be called twice (once implicitly and once
	  explicitly).  Thanks to Chris Lahey for pointing this out.

Mon Jan 15 12:44:29 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace: Created a new config symbol called ACE_HAS_ALLOCA_H.  This
	  is required to differentiate between AIX and other versions of
	  UNIX.  Thanks to Chris Lahey for pointing this out.

	* ace: moved config-hpux.h to config-hpux-9.x.h in anticipation of
	  the changes required to handle HP/UX 10.0!

Sun Jan 14 23:38:23 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.h (ACE_MAX3): Fixed the definition of ACE_MAX3 (it needed
	  a return value of template type T).  Thanks to Mark Zusman
	  <marklz@topaz.technion.ac.il> for noticing this.

	* ace: Added a new section to all the template files called
	  ACE_TEMPLATES_REQUIRE_SPECIALIZATION to deal with the screwy GNU
	  G++ semantics that are required if you *don't* have the template
	  repository patches.  Thanks to Mark Zusman
	  <marklz@topaz.technion.ac.il> for this.

Fri Jan 12 00:47:57 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Time_Value.h: #included <pthreads.h> to the Time_Value.h
	  class so that it would be the first file included.  This fixes a
	  problem with AIX.  Thanks to Chris Lahey for reporting this and
	  suggesting the fix.

	* ace: Fixed a braino with the #ifdefs in SPIPE_Stream and
	  SPIPE_Acceptor.  These were checking for ACE_WIN32 rather than
	  ACE_HAS_STREAM_PIPES.  Naturally, that failed on versions of
	  UNIX (e.g., Linux) that lack STREAM pipes!  Thanks to Neil Cohen
	  for taking time out of fighting blizzards to report this!

	* ace/Svc_Handler: Added a new method for handle_timeout, which
	  shuts things down by default.  Thanks to Irfan for suggesting
	  this.

	* Fixed a minor problem caused when Tim added the Double-Check
	  pattern to ACE_ODB...

Thu Jan 11 01:48:02 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Integrated AIX fixes from Chris Lahey <clahey@ix.netcom.com>.
	  These should allow ACE to build correctly using the AIX compiler
	  and it's screwy template mechanisms!

	* ace: Fixed some minor bugs that caused problems when compiling
	  with G++.

Wed Jan 10 00:17:05 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Trace.cpp: Fixed a typo that was causing problems when using
	  ACE_TRACE (we were ending up with recursive tracing in the
	  ACE_Trace class!).  Thanks to Detlef for noticing this.

	* ace/ACE.cpp: Moved methods from ACE.i to ACE.cpp and removed the
	  INLINE macro to deal with order of include problems with GNU
	  G++.

Tue Jan  9 19:00:41 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Task.i (flush): Added a check to make sure that msg_queue_
	  != 0 before trying to close() the queue.  This solves a problem
	  if the queue has already been closed.  Thanks to Alex V
	  Maclinvosky <alexm@teltrunk1.tait.co.nz> for reporting this...

	* tests/ASX/Event_Server/Event_Server: Fixed minor bugs in
	  Supplier_Router.cpp and Consumer_Router.cpp -- I was checking
	  for this->getq (mb) > 0 rather than this->getq (mb) >= 0.
	  Thanks to Alex V Maclinvosky <alexm@teltrunk1.tait.co.nz> for
	  noticing this...

	* ace/Synch_T.h: Commented out the ACE_ALLOC_HOOK stuff.  This is
	  causing order-of-include problems on HP/UX.  Also moved the
	  ACE_Null_Condition::wait() method to Synch_T.i to avoid the same
	  problem.  Thanks to Greg Baker
	  <GBaker@p01.az15m.iac.honeywell.com> for pointing this out.

Sun Jan  7 18:57:49 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Makefile: Added the Dump file to ACE.  Thanks to Tim for
	  fixing this up to make it ready for prime time.

	* Thanks to Craig Rodrigues <rodrigc@ecf.toronto.edu> for sending
	  me a new version of psnup that *finally* fixes the nasty
	  problems with "4-up" printing of postscript!  This makes it much
	  easier to distribute ACE documentation...

Sun Jan  7 18:31:07 1996  Tim H. Harrison  (harrison@merengue.cs.wustl.edu)

	* ace: Used the "Double-Check" pattern to eliminate potential race
	  conditions when using Singletons in multi-threaded programs.
	  Classes affected included ACE_[MS]T_CORBA_Handler, Name_Options,
	  Trace, and ACE_ODB.

Fri Jan  5 00:03:29 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.i: Added the following to OS.i:

	  #if defined (ACE_LACKS_SYSCALL)
	  int syscall (int, ACE_HANDLE, struct rusage *);
	  #endif /* ACE_LACKS_SYSCALL */

	  This should fix some problems with HP/UX.  Thanks to Walt Akers
	  (akers@cebaf.gov) for pointing out the problem.

	* ace/Handle_Set: Fixed the Handle_Set conversion operator so that
	  it returns fd_set * rather than ACE_FD_SET_TYPE *.  Thanks to
	  Walt Akers (akers@cebaf.gov) for pointing out the problem.

	* ace/Time_Value.h: I think I've fixed the problem with the order
	  of #includes with respect to POSIX and SVR4 time.  The trick was
	  to put this test in ace/Time_Value.h and then to make sure that
	  the ace/config.h file was included at this point!  Also changed
	  the symbol from ACE_HAS_POSIX_TIMERS to ACE_HAS_POSIX_TIME to be
	  more accurate.

Thu Jan  4 23:16:59 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/OS.i (gettimeofday): Changed the implementation of
	  gettimeofday() to use the ::_ftime call rather than the more
	  complex ::GetSystemTime(), ::SystemTimeToFileTime() duo.

Thu Jan  4 9:32:38 1996	  Chris Lahey (clahey@ix.netcom.com)

       * ace/config-aix.h: added #define ACE_TEMPLATES_REQUIRE_SOURCE 
         to make ACE work with AIX C++ compiler.

       * include/makeinclude/platform_aix.GNU:

         Added -qtempinc to the CPPFLAGS
	 Removed the PIC= definition completely

       * ace/Task.h: ACE_Task::svc() should not be declared as a pure
         virtual, removed = 0.

       * ace/Map_Manager.cpp: in trybind() member function, the line
           int_id = ss.int_id_;
	 should be:
	   int_id = search_structure[index].int_id_;

Thu Jan  4 01:23:38 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Map_Manager.cpp: Fixed a braino in Map_Manager -- didn't
	  need the <index> parameter to shared_bind().  Thanks to Tim for
	  finding this!

	* ace/Log_Msg.cpp (instance): Tim Harrison did a noble service to
	  humanity by fixing a potential race condition in the instance()
	  Singleton of ACE_Log_Msg.

Wed Jan  3 00:49:57 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace: Made some minor changes to fix portability problems with
	  SGI.  Fortunately, this should also fix some other problems with
	  HP/UX another other non-thread platforms.

	* ace/ACE.cpp (format_hexdump): Added Todd Montgomery's amazing
	  "format_hexdump" method to class ACE.

Tue Jan  2 20:47:57 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * ace/SV_Semaphore*: updated the interface of the _Simple and
	  _Complex System V semaphore wrappers to include the _read() and
	  _write() forms of acquire() and tryacquire().  Note that I've
	  implemented these as calls to acquire() and tryacquire(), so
	  they don't add any extra behavior.  This is needed for interface
	  conformance with other forms of ACE synchronization mechanisms.

	* ace/Time_Value.h: Changed the header to #include <sys/time.h>
	  in order to work around nasty "order of include" problems.

	* tests: Created a new directory called Win32.  This contains test
	  programs that This directory contains test programs that have
	  been compiled and tested successfully under Windows NT.  As we
	  get further along, we'll move this stuff into the general ACE
	  $WRAPPER_ROOT/tests directory (since of course all ACE programs
	  will run without any problems under Win32, right?  ;-)).  See
	  the ./tests/Win32/README file for instructions on how to build
	  these tests.

	* ace/Reactor.h: Moved the ACE_Handler_Repository out of the
	  ACE_MT_SAFE section of the code.  This was a "typo."  Thanks to
	  Walt Akers <akers@cebaf.gov> for reporting this.

Mon Jan  1 01:18:12 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/ACE.i: Moved the recv_n() and send_n() methods from ACE.cpp
	  into ACE.i and set things so that if __INLINE__ is set then
	  we'll inline those too!

	* ace: Irfan and I got the first major part of the Win32 to work
	  finally!  We made two socket programs (client and server) that
	  talked to each other and to UNIX.  Things are really starting to
	  take shape!
