Mon Feb 10 15:27:02 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Timer_Queue: Added a virtual destructor so that subclasses
 	  deleted via ACE_Timer_Queue *'s will call the right destructor.
  	  Thanks to Stuart Powell <stuartp@in.ot.com.au> for reporting
 	  this.

	* ace/Timer_Heap.cpp: Added support for automatically growing
 	  ACE_Timer_Heaps.  This allows heaps to grow automatically as new
 	  ACE_Event_Handlers are added dynamically.  Thanks to Stuart
 	  Powell <stuartp@in.ot.com.au> for this enhancement.

	* ace/Memory_Pool: Added support that allows flags to be passed in
 	  to the MMAP_Memory_Pool.  This can be used to set the
 	  appropriate type of backing store semantics (e.g., MAP_PRIVATE
 	  and MAP_SHARED).  Thanks to Fred LaBar
 	  <flabar@fallschurch.esys.com> for providing this.

Sun Feb  9 11:56:37 1997  Douglas C. Schmidt  <schmidt@polka.cs.wustl.edu>

	* ace/Map_Manager.cpp (bind_i): A recent change to Map_Manager
 	  broke the Connector since errno was getting set to ENOENT rather
 	  than EWOULDBLOCK.  Thanks to Mark Rabotnikov
 	  <mark@usp.elscintcorp.co.il> for finding this.

Sun Feb 09 21:44:34 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/ACE.{h,cpp}: added static u_long is_prime ().

	* ace/{OS.cpp,Thread_Priority.cpp}: added comment about thread
	  priorities only being tested for 1003.1C version of Pthreads.
	  Thanks to Thilo Kielmann <kielmann@informatik.uni-siegen.de>
	  for suggesting this.

	* ace/OS.{h,i}: added ACE_OS::clock_gettime ().  It allows
	  applications to get high-resolution time on POSIX systems.

	* ace/Future.cpp (dump): cast ref_count_ to an int because
	  g++ doesn't figure it out (it's an ACE_Atomic_Op<ACE_Thread_Mutex,
	  int>, which does have an int conversion operator).

	* ace/Timer_List.cpp (constructor): added initializer for
	  timer_id_ to prevent unitialized memory read report from Purify.

	* tests/IOStream_Test.cpp,Makefile: added IOStream_Test,
	  complements of James CE Johnson <jcej@lads.com>.  Very cool!

	* tests/Future_Test.cpp: replaced call to ::sin ()
	  with one to ACE::is_prime () to remove dependency on libm.

	* examples/IPC_SAP/UPIPE_SAP/ex1.cpp (peer1, peer2): removed
	  unused variables c_addr and serv_addr: they were replaced by
	  a global.

	* examples/Threads/future{1,2}.cpp: replaced call to ::sin ()
	  with one to ACE::is_prime () to remove dependency on libm.

	* netsvcs/clients/Naming/Dump_Restore/createfile.cpp: removed
	  #include of math.h, it wasn't needed.

Sat Feb 08 15:19:50 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/ReactorEx.h: commented out ACE_ReactorEx_Notify::message_queue_
	  declaration if not ACE_WIN32 because Sun C++ chokes on it.

	* examples/IPC_SAP/{FILE,SPIPE}_SAP/client.cpp: declare "len" as
	  ssize_t to avoid signed/unsigned comparison.

Fri Feb  7 01:13:05 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.i (select): Simplified Chris' fixes for the weird
	  Linux select() semantics.

	* ace/OS: Added a new accessor method called waiters() in
 	  ACE_cond_t that returns the number of waiters on the condition
 	  variable.  Thanks to Karlheinz for suggesting this.

	* ace/OS: Changed all the ACE_cont_t, ACE_rwlock_t, etc. so that
 	  their fields are private, but made class ACE_OS a friend.
  	  Applications should not be mucking with these fields since they
 	  may change.

	* ace/OS.h: Fixed a minor typo where friend class ACE_rwlock_t
 	  should be friend class ACE_OS.  Thanks to Thilo Kielmann
 	  <kielmann@informatik.uni-siegen.de> for reporting this.

	* ace/Log_Msg.cpp: Added a destructor to ACE_Log_Msg and changed
 	  ACE_TSS_cleanup so that it calls delete (ACE_Log_Msg *) ptr.
  	  Thanks to Per Anderson <Per.Andersson@hfera.ericsson.se> for
 	  reporting this.

	* tests/Map_Manager_Test.cpp: Create a file Map_Manager_Test_Key.h
 	  and move the class Key into the include file.  Include this *.h
 	  file in Map_Manager_Test.cpp.  This is needed for template
 	  generation on AIX.  Thanks to Chris Lahey <CLahey@cccis.com> for
 	  pointing this out.

Fri Feb  7 17:29:40 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

	* ace/OS.cpp (set_sched_params): added support for POSIX
	  threads.  Thanks to Thilo Kielmann
	  <kielmann@informatik.uni-siegen.de> for figuring it out and
	  for providing the code.

	* tests/Naming_Test.cpp (test_find): Changed final delete[] to
	  not try to delete a static buffer. :-(

	* tests/SOCK_Test.cpp (server): Added assertion test for
	  modified select timeval.

Fri Feb 07 13:56:24 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/{OS.cpp,Thread_Priority.cpp}: added ACE_Thread_Priority
	  support for Digital Unix.  Thanks to Thilo Kielmann
	  <kielmann@informatik.uni-siegen.de> for figuring the priorities
	  and priority classes out and for providing the code.

	* ace/High_Res_Timer.{h,cpp},config-linux*.h,README:
	  use struct timespec instead of timespec_t, because not all
	  platforms have the timespec_t typedef.  Thanks to
	  Marius Kjeldahl <marius@funcom.com> for reporting this on Linux
	  and Chris Lahey <CLahey@cccis.com> for reporting it on AIX.

	* ace/IOStream.h: use "ssize_t send (...)", etc., instead of exact
	  function prototypes.

	* examples/IPC_SAP/TLI_SAP/db-server.cpp: declare struct member as
	  const char * instead of const char [] because it's not static and
	  the struct doesn't have constructors.

	* examples/Reactor/Multicast/server.cpp (Server_Events ctor):
	  reordered initializers to match declaration order.

Fri Feb 07 05:08:51 1997    <irfan@cha-cha.cs.wustl.edu>

	* ace/ReactorEx: Complete rewrite of ReactorEx. This was done to
 	  allow multiple threads of control to wait simultaneously in
 	  ::WaitForMultipleObjects(). This was difficult because the
 	  handle set used in ReactorEx->handle_events() is shared between
 	  all threads. Care was necessary to make sure that changes to the
 	  handle set are serialized. This serialization was achieved by
 	  using multiple (auto and manual) events and mutexes.

	  Concept of "owner" thread is introduced in ReactorEx. The owner
 	  concept is used because we don't want multiple threads to try to
 	  expire timers. Therefore the "owner" thread is the only one
 	  allowed to expire timers. Initially, the creator thread of
 	  ReactorEx becomes the "owner" thread. Ownership can later be
 	  transferred among threads.

	  The Handler Repository also went through major changes as it now
 	  keeps track of <handle, event_handler> tuples to be added and
 	  deleted from the current handle set at the appropriate time
	  (i.e., when all threads are out of WaitForMultipleObjects() and
	  have completed all necessary dispatching).
	
	  Two slots will be added to the <size> parameter in the
 	  constructor and open methods of ReactorEx which will store
 	  handles used for internal management. Therefore, users can add
 	  upto MAXIMUM_WAIT_OBJECTS - 2 handles into ReactorEx.

	  Note that the interface to ReactorEx did not change in this
 	  process. Your existing code should work without changes.

	* examples/Reactor/ReactorEx/test_MT.cpp: This application tests
 	  multiple threads simultaneously calling
 	  ReactorEx->handle_events(). It also shows how different threads
 	  can update the state of ReactorEx.	

	* ace/Synch.cpp (dump): Fixed access error.

	* ace/OS.h: Fixed ACE_rwlock_t friend declaration.

	* ace/OS.i: Moved ACE_cond_t::waiters() such that it is now
 	  visiable to NT. Also fixed ACE_OS::cond_timed_wait by returning
 	  the correct return value on a TIMEOUT. Also fixed typo in
 	  ACE_OS::sema_wait.	

Thu Feb  6 20:25:13 1997  Chris Cleeland  <cleeland@cs.wustl.edu>

	* ace/OS.i (select): Adapted ACE_OS::select methods for use on
	  platforms (such as Linux) that allow select(2) to modify its
	  struct timeval arg.  New behavior is triggered by the define
	  ACE_HAS_NONCONST_SELECT_TIMEVAL.  Thanks to Jorn Jensen
	  <jornj@funcom.com> for reporting this!

Thu Feb 06 09:48:43 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/config-sunos-sun*.h,README: added
	  ACE_LACKS_LINEBUFFERED_STREAMBUF and ACE_LACKS_SIGNED_CHAR.

	* ace/IOStream.{h,cpp}: support
	  ACE_LACKS_LINEBUFFERED_STREAMBUF and ACE_LACKS_SIGNED_CHAR
	  so that this builds with SunC++.

	* examples/IOStream/client/iostream_client.cpp:
	  reordered args and fixed argv indexes.

	* examples/IOStream/server/iostream_server.cpp:
	  use ACE_DEFAULT_SERVER_PORT for default port.

	* tests/Naming_Test.cpp (randomize): changed type of "size" arg to
	  size_t to avoid compiler warnings about signed/unsigned comparison.

Thu Feb 06 09:40:47 1997  Chris Cleeland <cleeland@cs.wustl.edu>

	* ace/config-linux*.h: added typedef of timespec_t.

Wed Feb  5 01:45:03 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.i: Changed the Win32 implementation of all methods that call
	  WaitForMultipleObjects() so that errno is set to
	  WAIT_ABANDONED if the mutex is abandoned.  This makes it
	  possible for users to understand why ACE_OS methods that use
	  synchronization operations fail.  Thanks to Ivan Murphy
	  <Ivan.Murphy@med.siemens.de> for reporting this problem.

	* ace/IOStream.cpp (ACE_Streambuf): Moved the const initialization
 	  from the header file to the constructor since this is the only
 	  portable way to do this.  Thanks to Michael Maxie
 	  <maxie@acm.org> for reporting this.

	* ace/OS.i: Updated the call to thr_setprio() for pthreads so that
 	  it first determines the existing scheduling parameters and then
 	  updates the priority.  Thanks to Thilo Kielmann
 	  <kielmann@informatik.uni-siegen.de> for help with this.

	* ace/config-osf1-4.0*.h: Updated ACE_NEEDS_HUGE_THREAD_STACKSIZE
 	  to be 1 mega to minimize porting surprises.  Thanks to Thilo
 	  Kielmann <kielmann@informatik.uni-siegen.de> for help with this.

	* tests/Naming_Test.cpp: Cleaned up a few minor things related to
 	  int i = 0 vs. size_t i = 0.

	* ace/SOCK_Dgram.cpp: Added a new macro called
 	  ACE_HAS_SOCKADDR_MSG_NAME, which is used on platforms (e.g.,
 	  DG/UX) that require a cast to (struct sockaddr *) for the
 	  msg_name field of struct msghdr.

Wed Feb 05 10:45:41 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/IOStream.h: replaced __*manip with expanded types, because
	  Sun C++ doesn't have those typedefs; and added complete prototypes
	  for send, recv, send_n, and recv_n.

	* ace/IOStream.cpp: fixed "#define ACE_IOSTREAM_C" to keep g++ sane.

	* ace/Hash_Map_Manager.{h,cpp},Map_Manager.{h,cpp}: replaced
	  DEFAULT_SIZE with ACE_DEFAULT_MAP_SIZE so that Naming_Test runs
	  on SunC++ 4.1.

	* ace/High_Res_Timer.*: added optional scale factor.

	* examples/IOStream/{client,server}/Makefile:  addd -g++ if building
	  with gcc.

	* tests/Naming_Test.cpp: moved declaration of "i" out of for loop
	  because it is used after the loop.

	* examples/ASX/UPIPE_Event_server/{Consumer,Supplier}_Router.cpp
	  (open): return 1 if init () succeeds.  There's a commented-out
	  call to activate the objects that would (should?) return a value.

	* examples/IPC_SAP/FIFO_SAP/FIFO-client.cpp (main): declare n
	  as ssize_t instead of size_t to avoid compiler warning about
	  signed/unsigned comparison.

Tue Feb  4 19:06:52 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Signal.cpp: Fixed all the ACE_Sig_Handler[s] methods so that
 	  they now use ACE_Guard, rather than ACE_TSS_Guard, *unless* they
 	  are actually performing callbacks to user-code.  Not only is
 	  this faster, but it also avoids thread-specific storage key
 	  leaks on platforms like Solaris!

	* ace/OS.cpp (thr_keyfree): Added a new #ifdef for
 	  ACE_HAS_THR_KEYDELETE, which is defined for UNIXWARE.  This
 	  fixes a nasty problem with leaking thread-specific keys.  Thanks
 	  to Nigel Owen <Nigel@voicelink.co.nz> for reporting this.

	* ace/Message_Block.cpp: Added a #include for
	  "ace/Service_Config.h".

	* ace/Malloc.i: Fixed a few warnings by removing the names of
 	  unused parameters.

	* ace: Added many minor changes to ACE so that it will work on
 	  DG/UX.  Thanks to Michael Maxie <maxie@acm.org> for all these.

	* ace/LSOCK_Stream.cpp: Applied the same fix as to LSOCK.cpp.

	* ace/LSOCK.cpp: Removed the cast of 0 to (char *) for msg_name
 	  since some platforms use (struct sockaddr *).  By omitting the
 	  cast the compiler will figure it out correctly.  Thanks to
 	  Michael Maxie <maxie@acm.org> for this.

	* ace/IOStream: Added a new template adapter for creating an
 	  iostream-like object using an ACE IPC Stream for the actual I/O.
  	  Thanks to James CE Johnson <jcej@lads.com> for this.

	* examples/Misc/test_iostreams.cpp: Added a test that illustrates
 	  how the new ACE_iostreams mechanism works.  Thanks to James CE
 	  Johnson <jcej@lads.com> for this.

	* ace/Message_Block: Updated the ACE_Message_Block implementation
 	  to use ACE_Service_Config::alloc() if the user doesn't supply a
 	  customize version.  This also means that we never delete the
 	  allocator_strategy_, so we can remove this flag and reduce the
 	  amount of storage by 4 bytes.  Thanks to Irfan for noticing that
 	  we can do this.

	* ace/platform_dgux4_epc.h: Added a new platform config file
	  for DG/UX.  Thanks to Michael Maxie <maxie@acm.org> for
	  this.

	* ace/config-dgux-4.11-epc.h: Added a new config file for DG/UX.
  	  Thanks to Michael Maxie <maxie@acm.org> for this.

Tue Feb 04 18:26:01 1997    <irfan@cha-cha.cs.wustl.edu>

	* ace/Service_Config.cpp (alloc): The implementation now creates a
 	  ACE_New_Allocator rather than a ACE_Allocator_Adaptor.  If
	  you still want the old behavior, simply provide your own
	  custom allocator singleton for ACE_Service_Config.

	* ace/OS.i (mktemp): Added the missing ACE_INLINE directive.

	* ace/OS.h: ACE_HAS_INLINED_OSCALLS is now automatically defined
	  when __ACE_INLINE__ is defined.  This avoids mysterious linking
	  problems that occur otherwise.

	* ace/Malloc: Added a virtual destructor to ACE_Allocator.  Also
 	  added a new class ACE_New_Allocator which is a sub-class of
 	  ACE_Allocator. This class uses the new/delete operators to
 	  allocate and free up memory.  Please note that the only methods
 	  that are supported are malloc() and free(). All other
	  methods are no-ops.  If you require more functionality, please use:
 	  ACE_Allocator_Adapter <ACE_Malloc <ACE_LOCAL_MEMORY_POOL,
 	  MUTEX>> This will allow you to use the added functionality of
 	  bind/find/etc. while using the new/delete operators.

Mon Feb  3 15:35:24 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/config-aix-*.h: Added a (char *) cast to
 	  ACE_DEFAULT_BASE_ADDR.  Thanks to John Cosby
 	  <John.D.Cosby@cpmx.saic.com> for reporting this.

	* ace/OS.cpp: Added a new set() method that sets the Time_Value
 	  from a double.  Thanks to Brad Flood for this suggestion.

	* ace/OS: Changed ACE_OS::flock_t to ACE_OS::ace_flock_t to avoid
 	  a name clash on DG/UX.  Thanks to Michael Maxie <maxie@acm.org>
 	  for reporting this.

Tue Feb  4 03:02:52 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

	* tests/Naming_Test.cpp: Added timing and made debug print outs
 	  optional. Also added randomization of the test data.

	* ace/OS.h: Fixed prototype for gethrtime ()

Mon Feb 03 21:00:56 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/OS.h: define ACE_SCOPE_PROCESS and ACE_SCOPE_THREAD
	  even if ACE_HAS_THREADS is not defined.  Thanks to
	  Michael Maxie <maxie@acm.org> for pointing this out.

	* examples/Threads/{process_mutex.cpp,process_semaphore.cpp,
	  task_three.cpp,thread_manager.cpp,thread_specific.cpp} (main):
	  added ACE_UNUSED_ARG (sa);.

	* examples/Threads/reader_writer.cpp: fixed declaration of
	  "shared_data" to be "static volatile" instead of "volatile
	  static", and removed unused variable "n".

	* examples/Threads/thread_pool.cpp: removed unused variable "result".

Sun Feb 02 21:24:02 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/OS.h: changed hrtime_t to ACE_hrtime_t.

	* ace/{config-win*.h,README}: added #define ACE_HAS_PENTIUM to
	  enable gethrtime () support.

	* ace/High_Res_Time.{h,i,cpp}: removed platform-specific #ifdef's,
	  instead added "unsupported ()" static member function; changed
	  changed signature of elapsed_time to take time reference as
	  argument instead of return value; added elapsed_time
	  (ACE_Time_Value &) and elapsed_time_incr (ACE_Time_Value &).

	* examples/Thread/context_switch.cpp: use ACE_High_Res_Timer
	  instead of the old Timer adapter.

	* ace/config-aix-4.1.x.h: fixed typo: #defind ACE_HAS_LONGLONG_T.

	* ace/config-aix-4.2.x.h: added #define ACE_HAS_LONGLONG_T.

	* ace/Thread_Priority.{h,cpp}: moved #include of OS.h from .cpp
	  to .h file.

Sun Feb 02 10:30:29 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/Local_Name_Space.cpp: removed ACE_Map_Manager, ACE_Map_Iterator,
	  and ACE_Map_Entry: they don't appear to be used and, without
	  including their headers, this file won't compile.

	* ace/Hash_Map_Manager.cpp (Hash_Map_Manager (ACE_Allocator *)):
	  reordered initializers to match declaration order.

Sat Feb  1 15:11:28 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* include/makeinclude/platform_aix4.2.GNU (LD): Removed the -qnoro
 	  flag since it is no longer needed.  Thanks to Rob Jordan
 	  <jordan@hursley.ibm.com> for reporting this.

Sat Feb  1 03:25:21 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

	* ace/SString.cpp: Added two methods to the wide string
 	  implementation for high-performance. Even though these methods
 	  are somewhat ugly and not the "OO" way of doing things,
 	  performance was at stake here.

	* ace/Registry_Name_Space.cpp (resolve): Fixed the implementation
	  by correctly figuring out the size of the value in the
	  Registry. This allows us to dynamically allocated the correct
	  amount of memory.

	* ace/Registry: Fixed the constant MAX_CONTEXT_NAME_SIZE to be the
	  maximum path length.

	* ace/Naming_Context.cpp: Fixed various memory leaks.

	* ace/Local_Name_Space_T.h: Replaced the simple-minded Map_Manager
	  with the new (improved) Hash_Map_Manager.	

	* ace/Local_Name_Space.cpp: Added new methods operator!= and hash
 	  required by the map.

	* ace/Hash_Map_Manager.cpp (ACE_Hash_Map_Manager): Added an extra
	  constructor.

	* tests/Naming_Test.cpp: Removed memory leaks.

Fri Jan 31 19:39:48 1997  David L. Levine  <levine@cs.wustl.edu>

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

	* tests/Time_Value_Test.cpp: cast double argument to long
	  because there no longer is a constructor that takes a double.

	* ace/Hash_Map_Manager.{h,cpp}: removed #include of
	  ace/Hash_Map_Manager.i because it doesn't exist.
	  Protected .cpp file against multiple includes.  Moved
	  #include of "ace/Malloc.h" from .h to .cpp file.

	* ace/Map_Manager.cpp (current_size, total_size): cast -1 to
	  size_t to avoid warning about signed-to-unsigned conversion.

	* ace/OS.h: moved hrtime_t typedef for ACE_WIN32 so it doesn't
	  get defined twice.

	* ace/OS.i (getservbyname): one last ACE_HAS_NONCONST_GETBY change:
	  missed "lproto" to "proto".

	* bin/create_ace_build: added checks for existing symlinks, so
	  now the script can be re-run safely at any time on a build
	  tree to update it.

Fri Jan 31 02:16:30 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/config-aix-*.h: Made the default value for
 	  ACE_DEFAULT_BASE_ADDR 0x80000000 to work around restrictions
 	  with AIX.  Thanks to Rob Jordan <jordan@hursley.ibm.com> for
 	  this.

	* examples/Map_Manager: Added a new example of the
	  Hash_Map_Manager.

	* tests/Map_Manager: Integrated the Hash_Map_Manager into the
 	  Map_Manager test and greatly improved the test (e.g., by adding
 	  timing).

	* ace: Added a new implementation of the Map_Manager called
 	  Hash_Map_Manager.  This, of course, uses hashing rather than
 	  linear search.  The result should be a much faster
 	  implementation for many types of applications. 

Thu Jan 30 13:55:08 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Map_Manager: Changed the return type of total_size() and
 	  current_size() to size_t.

	* ace/OS: Had to remove the ACE_Time_Value (double) constructor
 	  since it caused ambiguities with ACE_Time_Value (long).  Thanks
 	  to Per Andersson for figuring this out.
  
	* include/makeinclude/platform_linux_lxpthread.GNU (CXX): Added
 	  -D_REENTRANT to make things work correctly in MT programs.
  	  Thanks to Marius for this fix.

	* ace/OS.h: Added several extra constructors for ACE_Time_Value so
 	  that it won't cause problems with the new ACE_Time_Value
	  (double) constructor.

	* ace/Log_Record.cpp (ACE_Log_Record): Added an "L" to the 0
 	  initial value used for time_stamp_.  Thanks to Marius for
 	  reporting this.

	* ace: Added the new config-aix-4.2.x.h file, which supports the
 	  AIX4.2 platform.  Thanks to Rob Jordan <jordan@hursley.ibm.com>
 	  for this.

	* include/makeinclude/platform_aix4.2.GNU: Added support for the
 	  new AIX4.2 platform.  Thanks to Rob Jordan
 	  <jordan@hursley.ibm.com> for this.
 
	* ace/OS.h: It's now possible to override ACE_DEFAULT_BASE_ADDR in
 	  a config.h file.  This is important for platforms that need to
 	  put shared memory segments at particular address ranges.  Thanks
 	  to Rob Jordan <jordan@hursley.ibm.com> for suggesting this.

Thu Jan 30 16:01:37 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/{config-aix-4.1.x.h,README}: added ACE_HAS_AIX_HIRES_TIMER,
	  see change to gettimeofday in OS.i below; and ACE_HAS_LONGLONG_T.

	* ace/OS.i (gettimeofday, gethrtime): use read_real_time () if
	  ACE_HAS_AIX_HIRES_TIMER.  Thanks to Bob Olson
	  <olson@mcs.anl.gov> for this suggestion.

	* ace/OS.h: define hrtime_t as long long if ACE_HAS_AIX_HIRES_TIMER.

	* ace/OS.{i,cpp}: uninlined ACE_OS::gethostbyname (),
	  and ACE_OS::inet_ntoa () on VxWorks, because they have
	  static char arrays.

	* ace/OS.i (gethostbyaddr, getservbyname, gethostbyaddr,
	  gethostbyname, getservbyname_r): with ACE_HAS_NONCONST_GETBY,
	  instead of copying the const argument, just cast it to (char *).
	  Thanks to Michael Maxie <maxie@acm.org> for pointing out the
	  problem with the nonstatic char arrays with sizes determined at
	  runtime.

	* ace/High_Res_Timer.*: added ACE_HAS_AIX_HIRES_TIMER support.
	  Also, renamed get_time () to elapsed_microseconds ().

	* examples/Threads/{Timer.h,context_switch_time.cpp}:
	  ACE_High_Res_Timer::elapsed_microseconds () instead of
	  ACE_High_Res_Timer::get_time ().

	* bin/create_ace_build: added this script: it creates an ACE build
	  tree in directory "build/<build name>" below the current
	  directory, which must be a ACE "top level" directory (such as
	  $WRAPPER_ROOT).  The build tree directory structure mirrors that
	  of the ACE top level directory structure, except that instead of
	  containing any plain files, it contains only symlinks to the files
	  in the ACE top level structure.

Thu Jan 30 06:57:50 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/Thread_Priority.cpp (convert_to_os_priority): changed
	  switch (priority_class) to switch (priority_class_).
	  Thanks to Chris Lahey <CLahey@cccis.com> for pointing this out.
	  Also, return -1 on other than Solaris, Win32, and VxWorks.

Wed Jan 29 22:05:01 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* tests/Naming_Test.cpp: Added the prefix "test_" to the bind(),
 	  find(), rebind(), and unbind() functions.  This avoids name
 	  clashes with the bind() call from the socket API.  Thanks to
 	  Marius for this info.
	  
	* ace/OS.cpp (ACE_Time_Value): Added a new constructor that makes
 	  it possible to construct an ACE_Time_Value from a double.
  	  Thanks to Brad Flood <BFLOOD@tcs.lmco.com> for this.

	* ace/OS.i (thr_join): If ACE_HAS_THREADS is defined, but none of
 	  the threading APIs match (e.g., AIX) then we'll return
 	  ACE_NOTSUP_RETURN(-1).  Thanks to Chris Lahey for help with
 	  this.

	* include/makeinclude/platform_aix.GNU: Made some changes to the
 	  type of dynamic linker and libraries used by AIX 4.1.  Thanks to
 	  Chris Lahey for help with this.

	* ace/config-aix-4.1.x.h: Changed from BSD 4.3 to 4.4.  Thanks
	  to Chris Lahey for help with this.

Wed Jan 29 09:03:48 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/OS.h: moved ACE_id_t and ACE_pri_t typedefs out of the
	  ACE_HAS_THREADS section.

	* ace/OS.cpp: fixed ACE_OS::set_sched_params on Win32 and VxWorks.

	* ace/Scheduling_Parameters.*, ace/Thread_Priority.*: updated
	  comments.

	* examples/Threads/{context_switch_time.cpp,Timer.h,Makefile}:
	  added context switch timing test.  Currently only works on
	  Suns because that's the only platform for which ACE has a
	  high-resolution timer.

	* Makefile: added chmod of VERSION file in TIMESTAMP macro.

Wed Jan 29 00:59:12 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* include/makeinclude/platform_linux_lxpthread.GNU (CXX): Removed
 	  the -D_MIT_POSIX_PTHREADS symbol since we're using Xavier's
 	  threads instead.  Thanks to Marius Kjeldahl <marius@funcom.com,
 	  mariusk@sn.no> for reporting this.

	* ace/config-linux-lxpthreads.h: Removed the _MIT_POSIX_PTHREADS
 	  symbol since we're using Xavier's threads instead.  Thanks to
 	  Marius Kjeldahl <marius@funcom.com, mariusk@sn.no> for reporting
 	  this.

Tue Jan 28 23:32:58 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/SString: Added hash() methods to each ACE String class so
 	  that we can use this with the new ACE_Hash_Set implementation of
 	  ACE_Map_Manager.

	* ace/ACE.h (ACE): Added a UNICODE version of hash_pjw() so that
 	  we can use it to hash ACE_WString.

	* ace/OS.i (thr_setprio): Fixed a typo that was left over from a
 	  previous change.  Thanks to Fred LaBar
 	  <flabar@fallschurch.esys.com> for reporting this.

	* apps/Gateway/Gateway/{proxy_config,consumer_config}: Added
 	  comments to these config files so they are easier to understand.
  	  Thanks to Chuck Gehr for motivating this.

	* apps/Gateway/Peer/Peer.cpp: Changed the name from connection_id_
 	  to proxy_id_, which is more accurate.

	* apps/Gateway/Peer/Peer.cpp: Added a destructor to Peer_Handler
 	  so that it can clean itself up properly when shutdown with a
 	  signal.  This fixes a nasty bug.

	* ace/config-win32-msvc4.x.h (ACE_HAS_MFC): By default, ACE now
 	  enables ACE_HAS_MFC.  This makes it possible to use
 	  AfxBeginThread() with the ACE_THR_AFX flag.

	* ace/OS.cpp: Fixed a typo in the call to ::AfxBeginThread()
 	  function.  Thanks to Karlheinz for reporting this.

	* apps/Gateway/Peer/Peer.cpp: Removed all uses of the Map_Manager
 	  from the Peer.  There's only ever one connection from a Gateway
 	  per-Peer, so what was this doing here anyway?!  It was causing
 	  problems due to multiple deletions, so removing it improves
 	  robustness of the tests.

	* ace/OS.i: Commented out the "extern char **_sys_siglist"
 	  definition since this was conflicting with the definition in
 	  Solaris.  If some platforms needs this, we'll need to add a
 	  specific #ifdef.

Tue Jan 28 21:57:45 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/OS.{h,cpp}:  added ACE_OS::set_sched_params ().  It permits
	  platform-independent setting of thread priorities and
	  priority classes.  It is currently supported on Solaris,
	  Win32, and VxWorks.

	* ace/Scheduling_Parameters.{h,i,cpp},
	  ace/Thread_Priority.{h,i,cpp}, ace/Makefile:
	  Added these two classes to support ACE_OS::set_sched_params ().

Tue Jan 28 12:42:39 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

	* ace/ace.mdp: Added the "Using MFC in a Shared DLL" flags.

	* tests/test_config.h (ACE_INIT_LOG): Made this UNICODE safe.

	* tests/Pipe_Test.cpp (main): Added an iteration count to control
	  the number of children created by the main process.

	* ace/Memory_Pool.cpp (init_acquire): cast this->minimum_bytes_ to
	  size_t to avoid compiler warning if size_t is unsigned.

	* ace/OS.h: Added strncat to the OS class.

Tue Jan 28 09:13:00 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/ACE.cpp (ACE::ldfind),
	  ace/Local_Name_Space_T.cpp,
	  ace/Local_Token.cpp (ACE_TPQ_Entry::ACE_TPQ_Entry),
	  ace/Log_Msg.cpp (ACE_Log_Msg::msg, ACE_Log_Msg::find),
	  Memory_Pool.cpp (ACE_MMAP_Memory_Pool::ACE_MMAP_Memory_Pool),
	  ace/Naming_Context.cpp (ACE_Naming_Context::open),
	  ace/Parse_Node.cpp (ACE_Location_Node::open_handle),
	  ace/Registry.cpp (ACE_Predefined_Naming_Contexts::is_local_host, 
                ACE_Registry::Binding_Iterator::Object_Iteration::next_n,
		ACE_Registry::Binding_Iterator::Context_Iteration::next_n),
	  tests/UPIPE_SAP_Test.cpp:
	  changed "sizeof char" to "sizeof (char)" because g++ and Sun C++
	  (properly) choked on it.

	* ace/Local_Name_Space_T.cpp (create_manager_i):
	  -- ::strncat () instead of ACE_OS::strcat ()
          -- "lock_name_for_backing_store" instead of
	     "lock_name_for_local_name_space"

	* ace/Naming_Context.cpp (both constructors): reordered
	  initializers to match declaration order.
 
	* include/makeinclude/platform_sunos5_g++.GNU: removed
	  -fno-strict-prototypes because it's not needed with SunOS 5.5.1.

Mon Jan 27 21:33:00 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

	* tests/Naming_Test.cpp (main): Made modifications to the test to
	  make it more dynamic.  Also made it work with UNICODE and
	  ACE_Naming_Context.

	* ace/Local_Name_Space_T.cpp (create_manager_i): Added a better
	  naming scheme for the locks.

	* ace: Changed the calculations of string lengths such that the
 	  size of the character type is carefully considered.

	  The following were affected:
	  
	  ACE.cpp (ACE::ldfind)
	  Local_Token.cpp (ACE_TPQ_Entry::ACE_TPQ_Entry)
	  Log_Msg.cpp (ACE_Log_Msg::msg, ACE_Log_Msg::find)
	  Memory_Pool.cpp (ACE_MMAP_Memory_Pool::ACE_MMAP_Memory_Pool)
	  Naming_Context.cpp (ACE_Naming_Context::open)
	  Parse_Node.cpp (ACE_Location_Node::open_handle)
	  Registry.cpp (ACE_Predefined_Naming_Contexts::is_local_host, 
                ACE_Registry::Binding_Iterator::Object_Iteration::next_n,
		ACE_Registry::Binding_Iterator::Context_Iteration::next_n)
			
	* ace/OS.h: Added UNICODE support for ACE_DEFAULT_LOCALNAME.

	* ace/Proactor.cpp: Redid "lost" changes to add UNICODE support to:

	  /* Proactor */
          ACE_Overlapped_File::ACE_Overlapped_File
          ACE_Overlapped_File::open

	* ace/Registry_Name_Space.h: Changed the order of #include and
	  #define as that the correct set of MACROS are defined for the
	  include files.

	* tests/MM_Shared_Memory_Test.cpp: Added UNICODE support.
	
Mon Jan 27 09:16:03 1997  David L. Levine  <levine@cs.wustl.edu>

	* include/makeinclude/platform_sunos5_sunc++.GNU,
	  include/makeinclude/platform_sunos5_sunc++_orbix.GNU,
	  ace/config-sunos5.5-sunc++-4.x-orbix.h
	  ace/config-sunos5.5-sunc++-4.x.h:
	  disabled exception handling by commenting out ACE_HAS_EXCEPTIONS
	  in the config files and adding -noex to the platform files,
	  because it causes trouble, at least on MP machines.

Mon Jan 27 14:54:31 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Memory_Pool.h: Added code to ACE_MMAP_Memory_Pool_Options to
 	  take a minimum_bytes parameter.  This is needed to prevent mmap
 	  remapping when a large segment is requested.  Thanks to Fred
 	  LaBar <flabar@fallschurch.esys.com> for this.

Sun Jan 26 13:39:13 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.i: Changed the typo sis_siglist to sys_siglist.  Also,
 	  changed the logic from #if !defined (ACE_HAS_SYS_SIGLIST) to
	  #if defined (ACE_HAS_SYS_SIGLIST) since this makes more sense...
  	  Thanks to Nanbor Wang <nw1@cs.wustl.edu> for noticing this.

Sat Jan 25 20:30:23 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/config-sunos5.5-sunc++-4.1.h: commented out ACE_HAS_EXCEPTIONS
	  #define because -noex is required with it, and that causes core
	  dump during thread exit on multiprocessor UltraSparcs.

	* include/makeinclude/platform_sunos5_sunc++_4.1.GNU: added -noex
	  back because of core dump during thread exit on
	  multiprocessor UltraSparcs.

	* examples/ASX/Event_Server/Event_Server/Event_Analyzer.cpp,
	  examples/ASX/UPIPE_Event_Server/Event_Analyzer.cpp (control):
	  added "default" case to switch statement to eliminate compiler
	  warnings about enumeration values not being handled in switch.

	* examples/ASX/UPIPE_Event_Server/event_server.cpp (consumer):
	  removed unused variable "iter".

Sat Jan 25 12:50:24 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.i: Updated all the cond_timedwait() and cond_wait()
 	  methods so that they decrement the count of waiters by one even
 	  when errors occur.  Thanks to Irfan for finding this.

	* ace/Map_Manager.cpp: Updated the ACE_Map_Iterator code so that
 	  it no longer crashes if the Map has been closed.  Thanks to
	  Slawomir Kuzniar <kuzniar@Bear.COM> for reporting this.

Sat Jan 25 11:34:56 1997  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

	* ace/SOCK_Connector.cpp (complete): Added a sleep of zero seconds
	  which allows non-blocking connects to work properly on NT.

	* ace/config-winnt-4.0-msvc4.x.h and config-win32-msvc4.x.h: 
	  Added ACE_HAS_BROKEN_NON_BLOCKING_CONNECTS.

	* ace/OS.i: Moved out all code for Time_Value from #if region. It
	  is common to all.

	* ace/Reactor: Added helper routines to stop the VC++ compiler from
	  bitching about destructors in exception handling code.

	* ace/ace.{mak,mdp}: Removed Time_Value.cpp from project.

	* tests/tests.{mak,mdp}: Corrected the creation of SOCK_Test and
	  Message_Blob_Test executables and temporary files.

Fri Jan 24 09:01:50 1997  David L. Levine  <levine@cs.wustl.edu>

	* examples/Connection/misc/Connection_Handler.cpp: added
	  specialization of ACE_Svc_Handler<ACE_SOCK_STREAM, ACE_NULL_SYNCH>
	  so that subproject will build with g++ without optimization.

	* apps/Gateway/Gateway/Proxy_Handler.cpp: added specializations
	  of ACE_Svc_Handler<ACE_SOCK_STREAM, ACE_SYNCH> and
	  ACE_Svc_Handler<ACE_SOCK_STREAM, ACE_NULL_SYNCH>
	  so that subproject will build with g++ without optimization.

	* tests/Reactor_Exceptions_Test.cpp (main): added ACE_UNUSED_ARG
	  for argc and argv when ACE_HAS_EXCEPTIONS is not defined.

	* performance-tests/Misc/test_mutex.cpp: made destructor of
	  Thread_Mutex_Derived virtual because the class has other virtual
	  functions.

Thu Jan 23 11:51:45 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/config-sunos5.5-g++.h: commented out ACE_HAS_EXCEPTIONS because
	  -fhandle-exceptions is broken in g++ 2.7.2 (and is required in order
	  to use exception handling); also, added ACE_HAS_INLINED_OSCALLS, if
	   __ACE_INLINE__ is #defined.

	* ace/config-sunos5.5-sunc++-4.1.h: added ACE_HAS_INLINED_OSCALLS,
	  if __ACE_INLINE__ is #defined.

Wed Jan 22 15:04:47 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.h: Moved the ACE_TIMER_SKEW macro to below the #inclusion
 	  of config.h and updated it so that it can be overridden in the
 	  config.h file if necessary.  Thanks to Bob Olson
 	  <olson@mcs.anl.gov> for motivating this.

	* ace/OS.cpp: Fixed the implementation of
 	  ACE_Thread_ID::operator== so that it works correctly when thread
 	  ids and thread handles aren't ints.  Thanks to Chuck Gehr for
 	  reporting this.

	* ace/OS.i (thr_getprio): Moved a stray #else into the right
 	  place.  Thanks to Chuck Gehr for reporting this.

	* ace/OS.i (sema_post): this->count_++ should have been
 	  s->count_++.  Thanks to Chuck Gehr for reporting this.

	* ace/Synch_T.cpp: Added an extern "C" definition for
 	  ACE_TSS_C_cleanup().  Thanks to Chuck Gehr for reporting this.

	* ace: Added a new #define called ACE_LACKS_SYS_NERR to the
	  config files for MVS and VxWorks.  This is used in OS.cpp
	  as follows:

	  #if defined (ACE_LACKS_SYS_NERR)
	  int sys_nerr = ERRMAX + 1;
	  #endif /* ACE_LACKS_SYS_NERR */

	  Thanks to Chuck Gehr for reporting this.

	* Removed all #inclusions of "ace/Time_Value.h."  This file
	  no longer contains anything besides a #include "ace/OS.h"
	  and is only kept around due to backwards compatibility.

	* ace: Moved the contents of Time_Value.h into OS.h to reduce the
 	  confusion that arises from the #inclusion of "config.h" in
 	  Time_Value.h.  Also merged the contents of Time_Value.{i,cpp}
 	  into OS.{i,cpp}.  Thanks to the MDA guys for motivating this.

	* tests/Reactor_Exceptions_Test.cpp: Added a new test that
 	  exercises the Reactor with C++ exceptions.  Thanks to Luca for
 	  the test.

	* ace/Reactor.cpp (handle_events): Added Win32 structured
 	  exception handling support to the ACE_Reactor::handle_events()
 	  method so that it correctly releases the token lock when Win32
 	  SEH occur in callback routines.  Thanks to Luca for reporting
 	  this problem.

	* ace: Added a new macro called ACE_HAS_EXCEPTIONS, which
 	  indicates that the compiler supports C++ exception handling.

	* include/makeinclude/platform_sunos5_sunc++*.GNU: Commented out
 	  the -noex flag for now.  Hopefully, things will work correctly
 	  now.

	* ace/Thread_Manager.cpp (exit): Removed the final acquire() on
 	  ace_mon, which is no longer necessary since the Guard classes
 	  now keep track of whether they are "owned".  Thanks to Karlheinz
 	  and Detlef for this fix.

Wed Jan 22 09:05:31 1997  David L. Levine  <levine@cs.wustl.edu>

	* Makefile,VERSION: modified top-level Makefile (and VERSION)
	  to add a timestamp to the VERSION file if creating a release
	  from the /project/adaptive/ACE_wrappers directory.  If it
	  causes problems, this will disable it:
	  % make  TIMESTAMP=  release.

	* ace/Local_Tokens.cpp (dump): replaced "ACE_TSS<ACE_TPQ_Entry>"
	  with "ACE_TPQ_ENTRY" so that ACE_NO_TSS_TOKENS is supported.

	* ace/Synch.h: fixed typo in comment header for ACE_Thread_Semaphore

	* ace/config-vxworks-ghs-1.8.h,config-vxworks5.2-g++.h,
	  config-unixware-2.01-g++.h:
	  protect ACE_HAS_INLINED_OSCALLS #defined with
	  #if defined (__ACE_INLINE__).

	* apps/Gateway/Gateway/Event_Channel.cpp (open): added
	  ACE_UNUSED_ARG (sig);.

	* examples/ASX/Event_Server/Event_Server/Peer_Router.h:
	  declared a friend of class Peer_Router_Context because it
	  has a private destructor, to eliminate compiler warning
	  about not having any friends.

	* examples/ASX/Event_Server/Event_Server/Supplier_Router.cpp
	  (open): added return 0 in "true" branch of if statement so
	  that the function always returns a value.

Tue Jan 21 09:19:44 1997  David L. Levine  <levine@cs.wustl.edu>

	* tests/Reader_Writer_Test.cpp (reader): commented out unused
	  variable "n"; also, commented out unused function
	  print_usage_and_die.

	* tests/TSS_Test.cpp, Thread_Manager_Test.cpp (main): added
	  ACE_UNUSED_ARG (sa);.

	* tests/Thread_Pool_Test.cpp (open):  added return 0 at end.

Tue Jan 21 11:00:12 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* apps/Gateway/Gateway/Gateway.cpp (parse_args): There was a small
 	  bug in parse_args (latest beta), it mixed proxy and consumer
 	  conf files.  Thanks to Per Andersson
 	  <Per.Andersson@hfera.ericsson.se> for reporting this.

Mon Jan 20 13:29:28 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/OS.i, ace/Task.h, and ace/Thread_Manager.h: changed a few
	  occurrences of NULL to 0 (for other than Win32 platforms),
	  primarily to avoid compiler warnings on VxWorks if ACE.h isn't
	  #included before stddef.h.

	* netsvcs/clients/Naming/Dump_Restore/Dump_Restore.cpp
	  (handle_input): replaced %d format with %hu for u_short arg.

	* netsvcs/clients/Tokens/deadlock/deadlock_detection_test.cpp
	  (run_writer): initialized variable "t" to avoid compiler warning.

	* examples/Connection/misc/Connection_Handler.cpp (handle_timeout):
	  added ACE_UNUSED_ARG (tv); also, added explicit int return type
	  to definition of Connection_Handler::close (u_long).

	* examples/Threads/task_four.cpp (Invoker_Task::svc):
	  moved declaration of "task" out of for loop because it is
	  also used after the for loop.

	* netsvcs/lib/Name_Handler.cpp, Server_Logging_Handler.cpp,
	  TS_Clerk_Handler.cpp, TS_Server_Handler.cpp, Token_Handler.cpp:
	  added ACE_UNUSED_ARG (sig);.

Sun Jan 19 11:10:49 1997  David L. Levine  <levine@cs.wustl.edu>

	* include/makeinclude/platform_sunos5_sunc++.GNU,
	  platform_sunos5_sunc++_4.1.GNU:
	  added comment about compiler warnings with +w option.
	  Also, added +w to platform_sunos5_sunc++_4.1.GNU.  With the
	  other changes in this ChangeLog entry, there no longer should
	  be significant warnings from Sun C++ when building ACE.

	* examples/ASX/Event_Server/Event_Server/Peer_Router.cpp
	  (Peer_Handler::put): added ACE_UNUSED_ARG (tv);.

	* examples/IPC_SAP/SPIPE_SAP/NPServer.cpp (main),
	  netsvcs/clients/Tokens/invariant/invariant.cpp (main):
	  commented out argc and argv.

	* examples/Mem_Map/file-reverse/file-reverse.cpp (main):
	  removed unused variable "cp".

	* netsvcs/clients/Tokens/manual/manual.cpp (handle_input,
	  handle_exception): added ACE_UNUSED_ARG (fd); and
	  (create_proxy): added return statement at end:  even
	  though it should never be reached, it eliminates a
	  compiler warning.

	* examples/OS/Process/process.cpp,
	  examples/Reactor/Misc/test_reactors.cpp,
	  netsvcs/clients/Tokens/deadlock/deadlock_detection_test.cpp,
	  netsvcs/clients/Tokens/mutex/test_mutex.cpp,
	  netsvcs/clients/Tokens/rw_lock/rw_locks.cpp,
	  performance-tests/TTCP/ORBeline/ttcp_i.cpp,
	  performance-tests/TTCP/Orbix/ttcp_i.cpp (main):
	  return 0 instead of 42.

Fri Jan 17 11:47:10 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.h: Added an equivalent set of
 	  ACE_LSOCK_{STREAM,ACCEPTOR,CONNECTOR} macros to complement the
 	  ones for ACE_SOCK_*.  Thanks to Gonzalo Diethelm
 	  <gonzo@ing.puc.cl> for suggesting this.

	* ace/OS.cpp (ACE_Thread_Adapter): Added a new feature that allows
 	  logging features to be inherited by threads.  It works with
 	  those OSs (e.g., Win32) that use ACE_Thread_Adapter class.  At
 	  some point, we might do this for all the OSs.  Thanks to Luca
 	  for this.

	* examples/Connection/misc/Connection_Handler.cpp: Added a
	  new example that illustrates how to use the Acceptor pattern
	  to create multiple threads, each running its own Reactor.

	* ace/Log_Msg.cpp (dump): Some of the variables in the dump()
 	  method have the wrong format specification type. These are:
 	  restart_ (%d), flags_ (%x), priority_mask_ (%d).  They are now
 	  fixed, thanks to Luca.

	* tests/Priority_Task_Test.cpp (open): Add an ACE_ASSERT to make
 	  sure that the tasks activate() correctly.  Thanks to David for
 	  finding this.

	* ace/config-linux-lxpthreads.h: Added #defines for
 	  ACE_HAS_AUTOMATIC_INIT_FINI and ACE_HAS_SVR4_DYNAMIC_LINKING.
  	  Thanks to Marius for this.

	* ace/Malloc.h: Changed the typedef of ACE_Malloc_Align to a macro
 	  called ACE_MALLOC_ALIGN to allow users to override this value in
 	  their config.h file.  This is necessary for platforms that don't
 	  have "long" word alignments.  Thanks to Fred LaBar
 	  <flabar@fallschurch.esys.com> for this suggestion.

	* ace/OS.h: Added an #ifdef check for ACE_HAS_IRIX62_THREADS and
 	  if so, we'll use the if (&a) /* null */; } form of the
 	  ACE_UNUSED_ARG macro to avoid unnecessary warnings.  Thanks to
 	  Fred LaBar <flabar@fallschurch.esys.com> for testing this out.

Fri Jan 17 16:33:25 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/High_Res_Timer.*: added elapsed_time () and get_time ().

	* netsvcs/clients/Tokens/collection/collection.cpp, rw_locks.cpp:
	  commented out unused variables to avoid compiler warnings; and
	  return 0 from main ().

	* include/makeinclude/rules.local.GNU,
	  netsvcs/lib/Makefile,
	  examples/Service_Configurator/IPC-tests/server/Makefile:
	  fixed ESOBUILD mechanism to work on all platforms, not just Linux.
	  Thanks to Marius Kjeldahl <marius@funcom.com> for this fix.

	* ace/OS.i and OS.cpp: uninlined functions that use varargs, because
	  they usually won't get inlined anyways.

	* ace/OS.cpp (thr_create): added #else clause to be sure that
	  always sparam.sched_priority always get set to the priority argument.

	* netsvcs/clients/Naming/Client/Client_Test.cpp: commented out
	  unused parameters and wrapped combined assignments/conditional
	  values to avoid compiler (g++) warnings.

	* tests/Priority_Task_Test.cpp: added check for successful thread
	  spawn, and ACE_NEW_THREAD to svc () so that messages get logged.

Thu Jan 16 17:03:47 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

	* include/makeinclude: Added support for shared object files
	  on Linux.  Thanks to Marius Kjeldahl <mariusk@sn.no,
	  marius@funcom.com> for his help with this. 

	* ace: Merged in the IRIX support, mainly the missing netdb reentrant 
	  functions.  Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl>
	  and Carlos O'Ryan <coryan@mat.puc.cl> for their help.

	* ace/Timer_{List,Heap,Queue}: Changed iterator() to iter() to
 	  avoid name clashes with STL (ugh).

	* ace/Timer_{Heap,List}.cpp: Added ACE_BUILD_DLL so that things
 	  will link.  Thanks to John Morey for reporting this.

	* ace/Synch_T.h: Fixed: class ACE_Write_Guard: method:
 	  tryacquire_write so that it will call
 	  ...->lock_->tryacquire_write() and not
 	  ...->lock_->acquire_write().  Thanks to Alexandre Karev
	  <Alexandre.Karev@cern.ch> for this fix.

Thu Jan 16 15:51:16 1997  David L. Levine  <levine@cs.wustl.edu>

	* Dump.cpp (register_object): initialized "slot" so that g++ doesn't
	  complain about uninitialized use.

	* Reactor.cpp (initialized): use ACE_GUARD_RETURN instead of
	  ACE_GUARD because the function returns a value;
	  (find): initialize "i" if handle is out of range so that g++
	  doesn't complain about uninitialized use.

	* Service_Repository.cpp (remove): removed unused variable "handle".

	* Thread_Manager.h: made destructor virtual now that spawn_i () is
	  virtual.

	* Timer_Heap.cpp: changed some int loop indicies to size_t to
	  make sure that comparisons are consistently signed or unsigned.

	* OS.h, config-vxworks*.h: removed ACE_HAS_GREENHILLS_SOCKETS
	  ACE macro because the code it wrapped applies to all VxWorks
	  compilers, not just GreenHills.

Wed Jan 15 02:06:21 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

	* ace/ACE.cpp (round_to_pagesize): If _SC_PAGESIZE is enabled then
 	  we set the ACE::pagesize_ variable using sysconf(2).  Thanks to
 	  James Mansion for this suggestion.

Wed Jan 15 02:06:21 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

	* ace/Timer_Queue.cpp (expire): Changed a line of code from
	
	  ACE_Timer_Queue_Iterator &iterator (this->iterator ());

	  to

	  ACE_Timer_Queue_Iterator &iterator = this->iterator ();

	  so that the Visual C++ compiler can grok it.  Thanks to John
 	  Morey for reporting this.

	* ace/Reactor.cpp: Modified the close() method so that it can be
 	  called multiple times with no bad side-effects.

	* ace/Pipe.cpp: Modified the close() method so that it can be
 	  called multiple times with no bad side-effects.

	* ace/Reactor: Added an initialized() method that indicates
 	  whether the Reactor was successfully initialized.  Also
 	  rearranged the code in ACE_Reactor::open() so that initialized_
 	  is only set at the end of the method when everything succeeds.
  	  If things *don't* succeed, we call close() on the way out.
  	  Thanks to Luca for these suggestions.

	* ace/Reactor.cpp (close): When closing down the ACE_Reactor, we
 	  now set initialized_ back to 0 so that it can be reopened again
 	  later.

	* tests/Reader_Writer_Test.cpp: There were some problems with this
 	  test due to the fact that on many pthreads platforms pthread_t
 	  isn't an int (it's a struct).  Thanks to Chuck Gehr
 	  <gehr@sweng.stortek.com> for the fix.

	* ace/OS.i (exit): In WIN32 when the process exits through an
 	  ExitProcess() call, some process resources (e.g., file handles)
 	  are freed before the static variable destructors are
 	  called. This results in an application error when tracing is
 	  enabled.  Removing the ACE_TRACE call in ~ACE_Event_Handler
	  seems to fix this.  Thanks to Luca for this fix.

	* ace/OS: Fixed the implementation of semaphores for the POSIX
 	  port (POSIX lacks semaphores).  The trick was to add a "waiters"
 	  field, along with the semaphore count.  Thanks to John Bossom
 	  <John.Bossom@Cognos.COM> for reporting this.

	* examples/Threads/wfmo.cpp: Added a new test program that seems
 	  to indicate that the Win32 WaitForMultipleObjects() function can
 	  be called in multiple threads, all of which wait on the same set
 	  of HANDLEs.  Note that the dispatching of the threads is
 	  relatively "fair" (i.e., everyone gets a chance to process the
 	  various HANDLEs as they become active).  Thanks to Ari Erev
 	  <Ari_Erev@comverse.com> for suggesting this and providing the
 	  initial code.

	* ace/Thread_Manager.h: Made the spawn_i() method virtual and
 	  moved it into the protected section of the class so that it can
 	  be over-ridden by subclasses.  Thanks to Tim Harrison for
 	  suggesting this.

Tue Jan 14 15:57:55 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

	* ace/OS.h: Changed the default size of ACE_DEFAULT_TIMERS to
 	  _SC_TIMER_MAX (which is typically around 40 or so).
	  Thanks to Stuart Powell <stuartp@in.ot.com.au> for
	  suggesting this.

	* tests/Timer_Queue_Test.cpp (main): Added some additional logic
 	  so that we can test the performance of the preallocated and
 	  non-preallocated ACE_Timer_Heap.

	* ace/Timer_Heap: Added a new "preallocate nodes" mechanism to the
 	  ACE_Timer_Heap.  If this is enabled by the constructor, then we
 	  preallocate as many ACE_Timer_Nodes as there are slots in the
 	  heap.  This allows us to completely remove the need for dynamic
 	  memory allocation, which is important for real-time systems.

	* ace/Thread_Manager.cpp (remove_thr): Optimized the code just a
 	  tad by decrementing the current_count_ *first*.  Thanks to Per
 	  Andersson <Per.Andersson@hfera.ericsson.se> for suggesting this.

	* ace/ReactorEx: Updated the implementation so that the
 	  handle_events() method now in fact *does* return the number of
 	  event handler's dispatched (i.e., the implementation matches the
 	  documentation...).  Thanks to Hamutal Yanay
 	  <Hamutal_Yanay@mail.icomverse.com> for reporting this.

	* ace/Service_Repository.cpp (remove): Removed an extra call to
 	  ACE_OS::dlclose().  This is already being called in the
 	  destructor of ACE_Service_Record.  Thanks to Karlheinz for
 	  reporting this.

	* man: Updated all the nroff and html documentation.

	* ace/Timer_Heap: Implemented the spiffy new timer cancellation
 	  algorithm that requires only O(log N) time to remove a timer
 	  from the ACE_Timer_Heap.  This is about 50 to 100 times faster
 	  than using the ACE_Timer_List implementation.

Tue Jan 14 21:01:36 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/OS.h: Replace "Linux" preprocessor symbol with "linux".

Mon Jan 13 17:57:50 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

	* ace/Synch: Added lock() accessor methods to both
 	  ACE_Process_Semaphore and ACE_Process_Mutex.  Thanks to Hamutal
 	  Yanay <Hamutal_Yanay@mail.icomverse.com> for suggesting this.

	* ace/config-mvs.h: Added a #define for ACE_HAS_GETPAGESIZE.
	  Thanks to Chuck Gehr for this information.

	* ace/LSOCK_Stream.h: Added a new typedef for PEER_ADDR that is
 	  associated with ACE_UNIX_Addr.  Thanks to Mark Rabotnikov
 	  <mark@usp.elscintcorp.co.il> for suggesting this.

Mon Jan 13 22:24:09 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/OS.h: Added #undefs of sigemptyset and sigfillset on Linux
	  when __OPTIMIZE__ is enabled.  Yes, the system header on Linux
	  really #defines them when optimizing!  Thanks to an anonymous
	  ACE user for pointing this out.

	* tests/tests_config.h: Dropped ACE_MAX_ITERATIONS back to 10.

Sun Jan 12 16:59:52 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

	* ace/Timer_List.cpp (schedule): Cleanup the code so that (1)
 	  timer_id never == -1 (in order to distinguish it from error
 	  return values and (2) so that we avoid an unnecessary check for
 	  operator new failure.

	* ace/OS.h: Added a new #define called ACE_DEFAULT_MAX_TIMERS,
 	  which specifies the maximum number of ACE_Event_Handlers
 	  supported by ACE_Timer_Heap.

	* ace/Proactor.cpp (ACE_Proactor): Updated the allocation of
 	  ACE_Timer_Queue so that it really points to an ACE_Timer_List by
 	  default.  Naturally, this can be overridden by users.

	* ace/ReactorEx.cpp (open): Updated the allocation of
 	  ACE_Timer_Queue so that it really points to an ACE_Timer_List by
 	  default.  Naturally, this can be overridden by users.

	* ace/Reactor.cpp (open): Updated the allocation of
 	  ACE_Timer_Queue so that it really points to an ACE_Timer_List by
 	  default.  Naturally, this can be overridden by users.

	* ace: Added two new classes called ACE_Timer_List and
 	  ACE_Timer_Heap, which derive from ACE_Timer_Queue.
  	  ACE_Timer_List is essentially the old behavior of
 	  ACE_Timer_Queue, i.e., it uses an implementation of a linked
 	  list of ACE_Timer_Nodes.  ACE_Timer_Heap, on the other hand,
 	  uses a heap-based callout queue, which is more appropriate for
 	  certain real-time applications.

	* ace/Timer_Queue: Revised the ACE_Timer_Queue implementation so
 	  that it's now an abstract base class with most of the
 	  implementation details pushed into the ACE_Timer_List and
 	  ACE_Timer_Heap subclasses.

	* ace/Timer_Queue.h: Made all the ACE_Timer_Queue methods public
 	  so that we can override them in a subclass (e.g., the new
 	  ACE_Timer_Heap).

	* examples/Logger/Acceptor-server/server_loggerd.cpp: Fixed this
 	  example application so that it only uses a single Reactor (the
 	  REACTOR::instance()) rather than two Reactors.  Thanks to Sandro
 	  Doro <alex@aureus.sublink.org> for reporting this.

	* netsvcs/lib/Logging_Strategy.cpp: Fixed the #include of
 	  fstream.h and iostream.h to use the '<' '>' notation rather than
 	  the '"' and '"' notation.  This avoids problems with running
 	  "make depend".  Thanks to Rino Simioni <sir@necsy.it> for
 	  reporting this fix.

Sun Jan 12 18:20:49 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/ACE.cpp (round_to_pagesize): fixed typo in reference to
	  ACE::pagesize_.

	* ace/ACE.cpp: initialize ACE::pagesize_ to 0.

	* ace/config-irix*.h and config-win*.h: removed ACE_PAGE_SIZE
	  definition because these platforms no longer use it.

	* tests/UNIX*.conf and Win32server.conf:  replaced net_svcs
	  with netsvcs.

Sat Jan 11 15:11:28 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

	* ace/OS.i (thr_setprio): The POSIX implementation of
 	  ACE_OS:thr_setprio did not set the priority.  It calls:

	  pthread_setschedparam( thr_id, &policy, &param )
 
          and then does
 
          prio = param.sched_priority.
 
          instead of

	  param.sched_priority = prio;
	  
	  This is now fixed.  Thanks to John Bossom <John.Bossom@Cognos.COM>
	  for reporting this.

	* ace/config-irix*.h: Modified all the IRIX config files to
	  use the new ACE_HAS_GETPAGESIZE feature since this is necessary 
	  to differentiate between IRIX and IRIX64.
	  Thanks to Fred LaBar <flabar@fallschurch.esys.com> for
	  reporting this.

	* ace/ACE.cpp: Modified the round_to_pagesize() so that if
	  a config.h file enables ACE_HAS_GETPAGESIZE then we use
	  that function in preference to the value in config.h.
	  Thanks to Fred LaBar <flabar@fallschurch.esys.com> for
	  suggesting this.

	* ace/ACE.cpp: Modified the round_to_pagesize() so that on
 	  platforms that allow the page size to be obtained dynamically
 	  we'll get that rather than replying on what it set in the
 	  config.h file.  We'll cache this value in a static variable
	  to speedup searches.  Thanks to James Mansion for suggesting
	  this.

	* apps/Gateway/Gateway: Finished adding support for thread-safe
 	  reference counting to the uses of ACE_Message_Block.

	* examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: Replaced
 	  the use of ACE_MT_SYNCH with ACE_SYNCH so that this will compile
 	  correctly on non-MT platforms.

Fri Jan 10 12:38:42 1997  Douglas C. Schmidt  <schmidt@flamenco.cs.wustl.edu>

	* Added a COPYING file that explicitly states the copyright status
 	  of ACE.

	* ace/config-win32-msvc4.x.h and ace/config-winnt-4.0-msvc4.x.h:
 	  By default, we'll revert to *not* enabling
 	  ACE_HAS_TEMPLATE_TYPEDEFS for MSVC++ 4.2, even though this is
 	  well-support by the compiler since it breaks some application
 	  code that expects to use 3 template parameters for
 	  ACE_Svc_Handler<>.  The "fix" is to use the ACE_SOCK_STREAM
 	  macros (rather than using the "ACE_SOCK_Stream, ACE_INET_Addr"
 	  tuple) in order to achieve portability in either case.  Thanks
 	  to Karlheinz for pointing out the need for backwards
 	  compatibility.

Wed Jan  8 01:00:05 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* tests/Message_Block_Test.cpp: Enhanced the torture test of the
 	  ACE_Message_Block so that it stresses the reference counting
 	  implementation in a multi-threaded environment.

Wed Jan 08 10:26:45 1997  David L. Levine  <levine@cs.wustl.edu>

	* ace/Message_Block.cpp (~ACE_Data_Block): assigned 0 to
	  allocator_strategry_ after deleting it; fixed template
	  specializations (for g++) by using macros instead of class names;
	  commented out template specializations because Service_Record.cpp
	  already has them, and they should only appear once in the library
	  in order to avoid link clashes

	* ace/Service_Object.cpp (ACE_Service_Object): reordered
	  initializations in constructor

	* ace/Service_Record.cpp (ACE_Service_Record): reordered
	  initializations in constructor

	* ace/config-linux-lxpthreads.h:  added
	  ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS, thanks to
	  James CE Johnson <jcej@lads.com> for tracking down this
	  problem and testing the fix.

Tue Jan  7 13:03:25 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Message_Block: Continued to improve the
	  ACE_Message_Block/ACE_Data_Block implementation.

	* ace/Message_Block: Added a new constructor to ACE_Message_Block
 	  that takes an ACE_Data_Block * and "owns" it.  Thanks to Tim for
 	  this idea.

	* ace/Log_Msg.cpp: Now that we've prevented signal handlers from
 	  occurring within critical sections of ACE_Log_Msg::log() we
 	  don't need to use the ACE_Recursive_Thread_Mutex anymore.
  	  Instead, we just need ACE_Thread_Mutex.

	* ace/Log_Msg.cpp (log): Added an ACE_Sig_Guard to the block in
 	  ACE_Log_Msg::log() that acquires the mutex that serializes
 	  output.  This prevents nasty problems with recursive to
 	  ACE_Log_Msg::log() from within signal handlers.

	* ace/Service_Config.cpp (end_reactor_event_loop): Added a timeout
 	  of ACE_Time_Value::zero to the ACE_Reactor::notify() method when
 	  called in the ACE_Service_Config::end_reactor_event_loop().
  	  This prevents the Reactor from blocking indefinitely if there's
 	  no longer a thread to receive from the notification pipe.
  
	* netsvcs/clients/Naming/Dump_Restore: Removed the vestigal
 	  nametest.cpp and nametest.h files.  I'm not sure why they were
 	  still there, but they shouldn't have been!

	* ace/Synch.i (remove): this->owner_ should be set to -1 before
 	  calling this->release().  Thanks to Per Andersson
 	  <Per.Andersson@hfera.ericsson.se> for suggesting this.

	* ace/Thread_Manager.cpp (exit): Added a flag called "do_thr_exit"
 	  to the ACE_Thread_Control::exit() method.  This controls whether
 	  we call ACE_OS::thr_exit() after removing the thread from the
 	  Thread Manager's internal table.  This is necessary to work
 	  around pthread bugs on certain platforms (e.g., AIX and Linux).

	* ace/Synch.h: Removed the
 	  ACE_Recursive_Thread_Mutex::set_nesting() method since this
 	  isn't being used and is potentially dangerous.  Thanks to Per
 	  Andersson <Per.Andersson@hfera.ericsson.se> for suggesting this.

	* ace/XtReactor: Updated the XtReactor so that it uses the next
 	  internal Reactor implementation.  Thanks to Mark Rabotnikov
 	  <mark@usp.elscintcorp.co.il> for reporting this.

	* ace/Task.i: Updated the grp_id(int) method to cache the group id
 	  in the task and then set it in the Thread_Manager, if there is
 	  one.  Thanks to Hamutal Yanay <Hamutal_Yanay@mail.icomverse.com>
 	  for suggesting this.

	* ace/Log_Record.h: Updated the ACE_Log_Record class to use the
 	  new ACE_MAXLOGMSGLEN macro.

	* ace/OS.h: Added a new #define called ACE_MAXLOGMSGLEN.  By
 	  default this is 4k.  However, you can reset it in the config.h
 	  file if you'd like to increase or decrease the size.  Thanks to
 	  Anthony McConnell for suggesting this.
	  
	* examples/Threads/tss[12].cpp: Tidied up the tss1.cpp and
 	  tss2.cpp examples and improved the comments.  Thanks to Luca for
 	  suggesting this.

	* ace/Service_Object.cpp (fini): Added the "virtual" keyword to
 	  the new destructor of ACE_Service_Type.  Thanks to David for
 	  reporting this.

	* ace/Message_Block.i: Rearranged the order of the ACE_Data_Block
 	  and ACE_Message_Block locking_strategy() methods so that they'd
 	  be defined as inline before being used.  Thanks to David for
 	  reporting this.

Mon Jan  6 16:46:06 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Service_Manager.cpp (fini): Only try to remove the
 	  ACE_Service_Manager from the Reactor if it's actually been
 	  registered in the first place (i.e., if it's get_handle() method
 	  does not return ACE_INVALID_HANDLE).

	* netsvcs/servers/svc.conf: Changed the name of the net services
 	  .so file from libnet_svcs to netsvcs so that it will work
 	  correctly with our new "cross-platform" svc.conf ACE::ldfind()
 	  strategy.  Thanks to Marius Kjeldahl <marius@funcom.com> for
 	  reporting this.

	* ace/Reactor.cpp (find): Added a strategic break and a check for
 	  handle_in_range().  Thanks to Tim for this help!

	* netsvcs/clients/Naming/Client/svc.conf: Removed the "lib" part
 	  from the executable shared object file names in the svc.conf
 	  file so that it will work with the new "cross-platform" svc.conf
 	  ACE::ldfind() strategy.  Thanks to Marius Kjeldahl
 	  <marius@funcom.com> for reporting this.

	* ace/Service_Record.cpp (fini): Added an extra assignment to a
 	  temporary const void *obj to avoid problems with MSVC++ and it's
 	  cast mechanism.

	* ace/ReactorEx.h: Added a default parameter to
 	  ACE_ReactorEx::notify().  Thanks to Tim for noticing this.

Sun Jan  5 10:48:23 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* tests: Added a new test for ACE_Message_Block, which is called
 	  Message_Block_Test.cpp (no surprise there ;-)).  This test
 	  exercises the reference counting mechanisms.

	* ace/Message_Block.h: Made the destructors for ACE_Message_Block
 	  and ACE_Data_Block virtual, so that these classes can be
 	  subclassed and ACE_Message_Blocks can delete these
	  subclasses (either via release() or delete).  Thanks to Tilo
	  Christ for suggesting this.

	* ace/Message_Block.cpp: Modified the implementation
	  of ACE_Message_Block/ACE_Data_Block so that we always create
	  an allocator_strategy_.  By default, this strategy will be
	  ACE_Allocator_Adapter <ACE_Malloc <ACE_Local_Memory_Pool, ACE_Null_Mutex> >;
	  This greatly simplifies the code.

	* ace/Message_Block.h: It's now possible to assign a
 	  Message_Block's priority when you create it.

	* ace/Reactor: Sped things up some more by merging the Reactor's
 	  any_ready() and fill_in_ready() methods together.  This reduces
 	  redundant computations.

	* ace/Reactor: Changed the name of ACE_Reactor::detach() to
 	  ACE_Reactor::remove_handler_i() and changed the name of
 	  ACE_Reactor::attach() to ACE_Reactor::register_handler_i().
  	  This is more consistent with the other naming schemes.

	* ace/Reactor.cpp: Reworked the implementation of the Handler
 	  Repository's unbind() method in order to simplfy the logic.
  	  Also merged in all the Reactor's detach() functionality into the
 	  unbind() method in order to localize all the handler removal
 	  processing.

	* ace/Reactor[Ex].cpp: Added more descriptive errno entries for
 	  failed operations in the handler repository.

	* ace/Reactor.cpp: Modified the implementation of the Handler
 	  Repository's bind() method so that it reports an error if you
 	  try to register an Event_Handler for an invalid HANDLE.

	* ace/Reactor.cpp: Reimplemented the internals of the Reactor to
 	  prepare for the upcoming merge of the Reactor and ReactorEx to
 	  use a single code base.

	* ace/Timer_Queue.cpp: Modified the behavior of the expire()
 	  methods so that they return the number of ACE_Event_Handlers
 	  whose handle_timeout() method was called.

Sat Jan  4 11:47:05 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Reactor.h: Removed the #ifdefs for ACE_HAS_POLL.  This will
 	  be recast as a strategy in subsequent implementations.

	* ace/Reactor.cpp: Added a new call,
 	  ACE_Handler_Repository::handle_in_range(), which checks to make
 	  sure that the HANDLE is within the range of 0 .. max_handlep1_.
  	  This factors out some redundant code.

	* ace/Reactor.cpp: Sped up the performance of the Reactor by
 	  removing redundant calls to
 	  ACE_Handler_Repository::invalid_handle() and
 	  ACE_Handler_Repository::find().

	* tests/Reactors_Test.cpp: Added a test for
 	  the new Reactor::notify() method with timeouts.

	* examples/Reactor/Misc/notification.cpp (svc): Added a test for
 	  the new Reactor::notify() method with timeouts.

	* ace/Reactor[Ex]: Modified the Reactor and ReactorEx so that they
 	  use timed send() operations for their notify() methods.  This
 	  makes it possible for users to bound the amount of time they're
 	  willing to wait to try and notify the Reactor.  This is mostly
 	  useful to avoid infinite blocking if there is congestion in the
 	  Reactor's notification mechanism.

	* ace/ACE.cpp: Added a new timed send() method that uses the
 	  write() system call on UNIX and the socket send() call on Win32.
  	  This new method is used in the new ACE_Reactor::notify() method,
 	  which now supported timed notifications.

	* ace/Reactor.cpp (ACE_Handler_Repository): To simplify the code
 	  and reduce unnecessary #ifdefs, I've merged the max_handlep1_
 	  and cur_size_ fields (which are now called max_handlep1_).

Fri Jan  3 10:47:15 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace: Replaced all uses of "delete mb" with mb->release ();

	* ace/Stream_Modules.cpp: Replaced the use of explicit bit
	  twiddling with the ACE_BIT* macros.

	* ace/Message_Block.cpp: Make sure that we use the
 	  allocator_strategy_ to create the memory for the reference count
 	  since this may need to go into shared memory if that's the
 	  memory pool where the Message_Block allocations are coming from.

	* ace/OS.h: Added two new macros, ACE_ALLOCATOR_RETURN and
	  ACE_ALLOCATOR, which are similar to ACE_NEW_RETURN and ACE_NEW, 
	  except that these

	* ace/Message_Block.cpp (release): Make sure to "delete this"
 	  outside the scope of the locking_strategy_.

	* ace/Service_Object.cpp: Added a destructor to ACE_Service_Type.
  	  Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for
 	  suggesting this.

	* ace/Service_Object.i: Be smarter about how we reassign the name_
 	  pointer, i.e., delete the old one and make a copy.  Thanks to
 	  Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting
 	  this.

	* ace/Module.cpp (open): Rearranged the assignments to
 	  reader_q->mod_ and writer_q->mod_ so that we don't try to
 	  initialize through NULL pointers.  Thanks to
 	  Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting
 	  this.

	* ace/Service_Record.cpp (ACE_Service_Record): Initialized name_
 	  to NULL so that the following change works correctly now.
  	  Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for
 	  reporting this.

	* ace/Service_Record.i (name): Make sure to delete [] (char *)
 	  this->name_ before allocating a new one.  Thanks to
 	  Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting
 	  this.

	* ace/Message_Block: Reworked the reference counting implemention
 	  so that reference counts are shared correctly amongst their
 	  various owners.  This requires making a deep copy the "header"
 	  portion, but a shallow copy of the "data."

	* ace/Message_Block.cpp (ACE_Message_Block): Updated all three
 	  ACE_Message_Block constructors so that they all call the init()
 	  method.  This centralizes all the initialization logic in one
 	  place.

	* ace/Message_Block.cpp (ACE_Message_Block): Make sure to set the
 	  cont_ field to 0 after "releasing" it so that we don't
 	  mistakenly think it's still around later on.  This problem arose
 	  in the ACE_Message_Queue::close() method, which was trying to
 	  count the number of bytes being freed.

	* ace/Message_Queue.cpp (close): Fixed a subtle bug where we
 	  weren't actually deleting messages from the
 	  ACE_Message_Queue::close() routine.  This should work now...

	* ace/Message_Queue.cpp (close): Replaced the use of "delete mb"
 	  with "mb->release()" since the Message_Blocks are now reference
 	  counted.  

	* ace/Message_Block: Enhanced the reference counting scheme so
 	  that you can increment and decrement the count by an arbitrary
 	  amount.  This is particular useful when you know you'll be
 	  sending the same Message_Block to N consumers.

	* ace/Singleton: The dump() must be used same as instance()
          (without supplying an object) so it must be declarated *static*,
	  i.e.,

	  static void dump (void);

	  Thanks to Sandro Doro <alex@aureus.sublink.org> for reporting
 	  this.

	* examples/ASX/Event_Server: Completely rewrote and retested the
 	  ACE Event Server example.  The new code is *much* easier to
 	  understand, has many more comments, is more robust, and compiles
 	  much faster since I removed many of the templates.

	* examples/ASX/Event_Server/Tranceiver/tranceiver.cpp: Fixed the
 	  tranceiver so that it shuts down correctly when the Event_Server
 	  exits.

	* examples/Connection/non_blocking/CPP-connector.cpp: Fixed a
 	  problem where we were trying to select() on ACE_STDIN on Win32.
  	  Naturally, this doesn't work, so we used the
 	  ACE::register_stdin_handler() to fix this.  Thanks to
 	  Samuel_Bercovici <Samuel_Bercovici_at_EFT__AD2@mail.icomverse.com>
	  for reporting this.

	* examples/ASX/Event_Server/Event_Server/Options: Changed the
 	  Options class to be a Singleton...

	* ace/Task.h: Added "const" method qualifier to accessor methods
 	  like is_reader() and is_writer().

Wed Jan  1 00:10:47 1997  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Message_Block: Added a new static release() method that
 	  behaves like the non-static method release(), except that it
 	  checks if <mb> is 0.  This is similar to CORBA::release(), which
 	  is useful if you want to eliminate lots of checks for NULL
 	  pointers before calling release() on them.

	* Updated all places in ACE where we use
 	  ACE_Event_Handler::READ_MASK when we should be using
 	  ACE_Event_Handler::ACCEPT_MASK.

	* examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp:
 	  Changed the name of the acceptor class from Handle_Thr_Stream to
 	  Handle_Thr_Acceptor, which is more accurate.

	* ace/Reactor: Since we've now got an
 	  ACE_Event_Handler::ACCEPT_MASK (intended primarily to accept
 	  connections asynchronously using Win32 overlapped I/O) we can
 	  now use this with the ACE_Reactor, as well.  In particular, any
 	  time that we are registering a "passive-mode" socket acceptor we
 	  can now specify ACE_Event_Handler::ACCEPT_MASK.  This is much
 	  more intuitive than using the READ_MASK (which never made any
 	  sense...).  The ACE_Reactor now treats the ACCEPT_MASK as a
 	  READ_MASK internally, so you can still use READ_MASK if you'd
 	  like (i.e., this change doesn't break any existing code).

	* ace/Event_Handler: Changed "get_priority" and "set_priority" to
 	  simply "priority(void)" and "priority(int)" to be more
 	  consistent with other parts of ACE.

	* apps/Gateway/Gateway: Updated the Gateway so that the
	  concurrency strategies can now be specified on the
	  command-line (or in the svc.conf file), rather than being
	  determined at compile-time.  This is much more flexible.
	  See the ./apps/Gateway/Gateway/README file for details.

	* apps/Gateway/Gateway: Verified that all the multi-threading
 	  strategies still work.

	* ace/Message_Block.cpp (ACE_Message_Block): Make sure that we
 	  "release" the continuation field, rather than delete it, since
 	  its reference count may be > 1.

	* ace/Log_Msg.cpp (log): Change the abort_prog logic a bit so that
 	  we always print a message to stderr if we're exiting,
 	  regardless...  Thanks to David Levine for pointing this out.

	* apps/Gateway/Gateway: Moved all of the configuration file
 	  parsing logic *outside* of the Event_Channel into the Gateway
 	  class so that we wouldn't have unnecessary dependencies.

	* apps/Gateway/Gateway: Redesigned the Gateway so that the
 	  Proxy_Handlers (i.e., the Consumer_Proxy and Supplier_Proxy)
 	  most of their work to the Event_Channel.  This "lightweight
 	  proxy" design is an improvement since it is now possible to
 	  emulate the COS Event Channel semantics within the Event_Channel
 	  "kernel."

	* Happy new year!  Let's start a new ChangeLog to celebrate the
	  new year.
