Fri Nov  1 00:25:01 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Service_Repository.cpp (remove): Fixed a bug with
 	  Service_Record::remove() that was failing if there were only two
 	  records and we are removing the first one.  Thanks to Alex
 	  Villazon <villazon@cui.unige.ch> for reporting this.

	* ace: Recompiled everything on Solaris with G++ and CC and it
	  seems to work fine.

	* ace/Module: Replaced the use of char * with const char * for
 	  assigning the Module a name.

	* ace: Split the Task.{cpp,i.h} file into Task_T.{cpp,i,h} in
 	  order to factor out the new non-template ACE_Task_Base and
 	  ACE_Task_Exit classes.  This is required for GCC-based compilers
 	  that include the *.cpp files...

Thu Oct 31 00:36:38 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Malloc_T.h: Made the destructor of ACE_Allocator_Adapter
 	  virtual.

	* ace/Thread: Reorganized the ACE_Thread so that the
 	  ACE_HAS_THREADS #ifdef is no longer required...

	* ace/Strategies.h: Changed all the destructors to be virtual so
 	  that G++ will stop complaining...

	* ace/Thread_Manager: Reorganized the ACE_Thread_Manager so that
 	  the ACE_HAS_THREADS #ifdef is no longer required...

	* ace/config-win32-msvc4.0.h: Added Dieter Quehl's great hack to
 	  get ACE to compile correctly on Win32 with MFC!

	* ace/Task: I've rearranged the implementation of ACE_Task<> 
	  in the following way:  

	     1. Defined a non-template class ACE_Task_Base from which the 
	        ACE_Task<...> inherits (instead of inheriting from
		Ace_Service_Object, which ACE_Task_Base now inherits from.
     
	     2. Move all methods that don't depend on the <ACE_MT_SYNCH> or
	        <ACE_NULL_SYNCH> modifers from the ACE_Task template to
		ACE_Task_Base.

	  There are two motivations for making this change:

	     1. It reduces ``template bloat'' by factoring out common
        	code that can be shared between ACE_Task<ACE_MT_SYNCH>
		and ACE_Task<ACE_NULL_SYNCH>.

	     2. It makes it possible for the Thread_Manager to use 
	        ACE_Task_Base *'s for managing groups of ACE_Tasks
		in a fully polymorphic manner.

	  Note that the new changes don't break any existing code that
	  uses ACE_Task.  Thanks to Hamutal Yanay
	  <Hamutal_Yanay@hub.comverse.com> and Ari Erev's
	  <Ari_Erev@comverse.com> for suggesting these changes.  

	* ace/Thread_Manager: Changed the use of ACE_Task<ACE_SYNCH> to
	  ACE_Service_Object because this avoids nasty problems with
	  template type conflicts.  The right solution is probably to
	  create a new non-template base class for ACE_Task called
	  ACE_Task_Base and move all the ACE_Task operations into there
	  that don't involve the Message_Queue directly.  I'll need to
	  think more about this...

	* ace/SOCK_Stream: Added new timed send_n() and recv_n() methods,
 	  which use the underlying timed ACE::send() and ACE::recv()
 	  calls.

	* ace/ACE.cpp: Added new timed send_n() and recv_n() methods,
 	  which use the underlying timed ACE::send() and ACE::recv()
 	  calls.

Wed Oct 30 00:27:21 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.h: Changed MAXHOSTNAMELEN on Win32 from
	  (MAX_COMPUTERNAME_LENGTH+1) (which is around 16 or so) to 256.
  	  Thanks to Tilo Christ <christ@swl.fh-heilbronn.de> for this
 	  suggestion.

	* ace: Made #define STRICT a compile time option if the
 	  ACE_HAS_STRICT flag is enabled.  This prevents ACE from breaking
 	  existing application (i.e., non-ACE) code.  Thanks to Karlheinz
 	  for pointing this out!

	* ace/Synch_T.cpp: Fixed a typo in ACE_Condition<MUTEX>::wait
 	  (void).

	  return ACE_OS::cond_wait (&this->cond_, this->mutex_.lock_);

	  should read 

	  return ACE_OS::cond_wait (&this->cond_, &this->mutex_.lock_);

	  Thanks to Dieter Quehl <dietrich.quehl@med.siemens.de> for
 	  reporting this!

	* ace/Svc_Handler.h: Removed the operator ACE_PEER_STREAM &() from
 	  the ACE_Svc_Handler class since we don't need it anymore due to
 	  the changes below.

	* ace/{Acceptor,Connector}.cpp: Removed the use of operator
 	  ACE_PEER_STREAM &() in the Acceptor::accept() and
 	  Connector::connect() code and replaced it with
 	  svc_handler->peer().  This works much better and is more
 	  intuitive.

Wed Oct 30 00:30:00 1996  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

	* Registry: Added a Name Service implementation to ACE based on
 	  Win32 Registry. The ACE_Registry interface is inspired by the
 	  interface specified in the CORBA Naming Service Specification.
  	  The implementation is done through Win32 Reg*() functions.
  	  Other than providing an OO wrapper for the Win32 Reg*()
 	  functions, ACE_Registry provides an abstraction for iteration
 	  over the elements of the Registry. This only works on Win32
 	  platforms (unless you are brave enough to reimplement the
	  Win32 Registry API on UNIX and link it in underneath ACE!).

	* ace/Local_Name_Space_T.cpp: Moved SEH out of methods of
	  Name_Space_Map to the methods of Local_Name_Space. Some of
	  the calls to Local_Name_Space methods used the allocator to
	  either malloc or find or free shared memory. Adding SEH to these 
	  methods ensured that any exception raised due to remapping would
	  be caught and handled appropriately. 

	  Also, to fool the stupid MFC compiler, we added _i methods
	  so that it stopped bitching about destructors not getting called
	  correctly. 

	* Added three new tests to /examples/Naming. Thanks to Lothar for
	  providing these tests.  

Tue Oct 29 18:10:09 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/ACE.cpp (send): Integrated a new and simpler version of
 	  timed ACE::send().  Thanks to Vital Aza <va3@cs.wustl.edu> for
 	  coming up with this.

	* ace/XtReactor.cpp: When the ACE_Reactor is constructed it
 	  creates the notify pipe and registers it with the attach()
 	  method. The XtReactor overloads this method BUT because the
 	  attach occurs when constructing the base class ACE_Reactor, the
 	  ACE_Reactor attach() is called not the XtReactor attach().  This
 	  means that the notify pipe is registered with the ACE_Reactor
 	  event handling code not the XtReactor and so notfications don't
 	  work.  To get around this we simply close and re-opened the
 	  notification handler in the constructor of the XtReactor.
  	  Thanks to Rodney Skinner <rods@in.ot.com.au> for this fix.

	* ace/XtReactor.cpp (schedule_timer): The ACE_Reactor returns a
 	  timer_id from it's equivalent call but the XtReactor always
 	  returns 0.  To fix this we simply replaced the "return 0;" in
 	  the function with "return result;" Thanks to Rodney Skinner
 	  <rods@in.ot.com.au> for reporting this.

Tue Oct 29 00:02:44 1996  Douglas C. Schmidt  <schmidt@lambada.cs.wustl.edu>

	* ace/config-win32-msvc4.0.h: Defined the STRICT symbol based on a
 	  suggestion from Luca.  STRICT type checking in WINDOWS.H
 	  enhances type safety for Windows programs by using distinct
 	  types to represent all the different HANDLES in Windows. So for
 	  example, STRICT prevents you from mistakenly passing an HPEN to
 	  a routine expecting an HBITMAP.  Note that if you have STRICT
 	  type checking enabled in one file, but not in another, the C++
 	  compiler will generate different external link symbols for a
 	  single function. This will result in link-time errors If you are
 	  mixing STRICT and non-STRICT code, you must be aware of linkage
 	  inconsistencies. In general, all MFC programming and all C++
 	  should be done with STRICT. If you have legacy C code, then not
 	  using STRICT is acceptable

	* ace/OS.cpp (thr_create): Added a special check for the situation
 	  where we have both ACE_HAS_PTHREADS and ACE_HAS_STHREADS
 	  defined.  In this case, we are running on Solaris, where
 	  ACE_thread_t and ACE_hthread_t are the same.  Therefore, we can
 	  copy the value of the *thr_id into the *thr_handle.  This
 	  ensures that the ACE_Thread_Manager behaves correctly with
 	  respect to suspending and resuming threads and ACE_Tasks.

	* ace/Trace.cpp (ACE_Trace): Changed the use of LM_DEBUG to
 	  LM_TRACE in the constructor and destructor.  Thanks to Luca for
 	  this!

	* ace/OS.i: Added a cast to of (HMODULE) handle so that the STRICT
 	  macro would work correctly for Win32.  Thanks to Luca for this.

	* ace/config-win32-msvc4.0.h: According to Luca, ACE compiles file
 	  with ACE_LACKS_STATIC_DATA_MEMBER_TEMPLATES undefined on NT.  So
 	  I undefined it!  If there are any problems with this, please let
 	  me know.
	  
	* ace/SOCK_Dgram: Added Luca Priorelli <lucapri@mbox.vol.it>
 	  implementation of recv() for SOCK Dgrams that allows clients to
 	  read from a socket without having to provide a buffer to read.

	* examples/Threads/test_task_four.cpp: This is a new test
	  program to test the new interfaces.  Thanks to Hamutal Yanay
	  & Ari Erev for this.

	* tests/test_config.h: Added a call to the new ACE_OS::mkdir()
 	  wrapper to create the log directory if one doesn't already
 	  exist.  This should solve some nasty problems with NT reported
 	  by Tilo Christ <christ@swl.fh-heilbronn.de>.

	* ace/OS.h: Added a new macro ACE_DEFAULT_DIR_PERMS and changed
 	  the spelling of the existing ACE_DEFAULT_PERMS to
 	  ACE_DEFAULT_FILE_PERMS, which is more accurate.

Mon Oct 28 21:35:12 1996  Douglas C. Schmidt  <schmidt@lambada.cs.wustl.edu>

	* ace/OS.h: Added a wrapper for the mkdir() system call.  We need
 	  it for some of the tests.

	* ace/Task: Changed the name of ACE_Task_Exit<>::set_this() to
 	  ACE_Task_Exit<>::set_task().  Thanks to Hamutal Yanay & Ari Erev
 	  for suggesting this.

	* ace/{Task,Thread_Manager}: Integrated Hamutal
	  <Hamutal_Yanay@hub.comverse.com> Yanay & Ari Erev's
	  <Ari_Erev@comverse.com> enhancements to add ACE_Task support
	  to the ACE_Thread_Manager.  This allows the ACE_Thread_Manager to
	  know about ACE_Tasks directly, rather than knowing
	  indirectly via their lower-level thread IDs.  The changes
	  are described below:

	   - Added a parameter to the activate() method. It is used to
 	     pass an ACE_Task* to spawn_n().

	   - Modified suspend() and resume() to call
 	     thrMgr->suspend_task() and thrMgr->resume_task() instead of
 	     thrMgr->suspend_grp() and thrMgr->resume_grp().

	   - Added an ACE_Task * parameter to spawn_n().

	   - Added an ACE_Task * parameter to append_thr().

	   - append_thr() uses the ACE_Task * input parameter to
 	     initialize the thread descriptor.

	   - Added the following methods:
	       apply_task()
	       suspend_task()
	       resume_task()
	       kill_task()
	       resume_task()
	       cancel_task()
	       find_task()

	       num_tasks_in_group()
	       num_threads_in_tasks()

	       task_list()
	       thread_list()
	       hthread_list()

	       set_grp() Like the current set_grp() but gets an ACE_Task *
	                 as input. 
	       get_grp() Like the current set_grp() but outputs an
	                 ACE_Task *. 

	       wait_task() 
	       wait_group()

Sun Oct 27 11:25:00 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS: modified the ACE_OSCALL_RETURN macro so that we'll
	  no longer have zillions of warnings about _result not
	  used...

	* ace/Synch_T: Changed the use of ACE_Mutex for ACE_TSS to
 	  ACE_Thread_Mutex.

	* ace: Added the necessary template specializations to get ACE
 	  compiled correctly with G++.

	* ace/Log_Msg.h: There were some places in the ACE_{DEBUG,ERROR}
 	  macros that should have been using __ace_error but there still
 	  using errno (which is wrong since this might be changed due to
 	  side-effects of calling ACE_Log_Msg::instance()).  I found this
 	  problem due to the use of -Wall with G++!  As a result of this
	  fix, ACE now compiles much more cleanly with gcc -Wall.

	* ace/Strategy: Improved the scheme used to define the PEER_ADDR
 	  type of the ACE_Accept_Strategy so that it will work correctly
 	  on platforms whose C++ compilers aren't quite up to handling all
 	  variants of template typedefs.  In particular, many platforms
 	  don't support the use of template typedefs in parameter names...

	* ace/OS: HP/UX omitted the const in the prototype of
 	  const_timewait().  Therefore, I added a new typedef to handle
 	  this and updated all the HP/UX config*.h files.

	* ace: Added a new config file (config-sunos5.5-sunc++-4.1.h)
 	  which reflects the fact that SunC++ 4.1 fixes template bugs that
 	  prevented earlier versions from supporting template typedefs
 	  correctly.  The new config file #defines
 	  ACE_HAS_TEMPLATE_TYPEDEFS.

Sat Oct 26 02:22:25 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace: On the advice of David Levine, I compiled ACE with gcc
 	  -Wall and started to fix lots of minor warnings (e.g.,
 	  misordered data member initializations).

	* ace/Local_Tokens.h: Changed the destructors of ACE_Mutex_Token,
 	  ACE_RW_Token, ACE_Token_Proxy, and ACE_RW_Token to be virtual.

	* ace/Synch_T.h: Changed the destructor of ACE_TSS to be virtual.

	* ace/OS: Changed the prototype of ACE_OS::select() so that it
 	  uses const ACE_Time_Value *.

	* Updated all uses of ACE_Malloc to use the new ACE_*_MEMORY_POOL
 	  #defines.  This makes it possible to use the ACE_Malloc<> scheme
 	  with lame C++ compilers.

	* ace/ACE: Changed the interface of the new timed send/recv calls
 	  to use ACE_Time_Value *, which makes it easier to determine
	  the blocking semantics at runtime.  Thanks to Bill Fulton
 	  <bill@fasttrack2.bscc.bls.com> for suggesting this.

Sat Oct 26 15:55:02 1996  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

	* ace/OS.h: We determined that MSVC++ is capable of supporting
 	  template typedefs.  Therefore, we can enable the
	  ACE_HAS_TEMPLATE_TYPEDEFS flag, which makes life much easier for
	  end users!

Fri Oct 25 23:16:16 1996  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

	* examples/Shared_Malloc/test_multiple_mallocs.cpp: Added a new
 	  test that demonstrates the new ability of ACE_Malloc<> to to
 	  handle multiple mallocs rooted at different base addresses.

	* ace/Memory_Pool: Fixed this stuff so that it works even when C++
 	  compilers can't grok template typedefs.

	* ace: Put all the macros that handle the fact that many C++
 	  compilers have broken template implementations into one place
	  (OS.h), rather than having this spread out in many files.

	* In ACE_MMAP_Memory_Pool::init_acquire (), we reset errno to 0 in
 	  the case where the file already exists (and errno == EEXIST).

	* Added an ACE_*_Memory_Pool_Options class to each Memory Pool
 	  class. The Options class allows detailed parameters to be passed
 	  to the constructor of the Memory Pool class. Since a typedef'd
 	  Options class was added to every Memory Pool class, this gave us
 	  the ability to use traits in ACE_Malloc and
 	  ACE_Allocator_Adapter to construct generic Memory Pools that can
 	  be initialized uniquely for each instance of ACE_Malloc.  Note
 	  that this new feature only works for C++ compilers that support
 	  template typedefs correctly (e.g., MSVC++ 4.x, SunC++ 4.1,
	  and the AIX C++ compiler).

	* Added additional constructors to ACE_Malloc and
 	  ACE_Allocator_Adapter to allow Options to be passed in to Memory
 	  Pool.

	* Added an extra field in ACE_Name_Options which allows
 	  specification of the base address of the memory pool. This is
 	  now used by ACE_Local_Name_Space::create_manager() to create an
 	  ACE_Allocator_Adapter.  This now allows us to have multiple
 	  ACE_Naming_Context simultaneously in the same process address
 	  space.

	* Also added error checking for constructors (in
 	  ACE_Local_Name_Space and ACE_Malloc) by checking errno
 	  values. This is a "hack" since we currently do not use exception
 	  handling.

Thu Oct 24 02:43:11 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* examples/Connection/misc/Makefile: The Makefile in
 	  ACE_wrappers/examples/Connection/misc seems to have been
 	  truncated.  I replaced it.  Thanks to Alan Stewart
 	  <axs2@osi.com> for reporting this.

	* examples/IPC_SAP/SOCK_SAP/CPP-{inclient,inserver}.cpp: Updated
 	  these examples to use the new timed send()/recv() operations.

	* ace/SOCK_IO: Added timed send()/recv() methods, using the base
 	  level implementations in class ACE.

	* ace/ACE: Added timed send()/recv() methods.

Wed Oct 23 19:56:45 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* examples/IPC_SAP/SOCK_SAP/CPP-inclient.cpp (main): Changed the
 	  behavior of the test program so that it doesn't take a
 	  local_addr, but rather will use the default (this prevents a
 	  common problem that happens when users run the test without
 	  reading the README file).

	* ace/ACE.cpp: Added a new method (get_flags) that returns the
 	  current setting of flags associated with handle.

	* Start of a brave new world: ACE is now under CVS version
 	  control...  Thanks to David Levine and Chris Cleeland
	  for making this happen.

Sat Oct 19 12:33:56 1996  David L. Levine  <levine@cs.wustl.edu>

	* added ACE threads mappings to VxWorks 5.2 tasks in OS.*.
	  NOTE:  this is _untested_ at this point, but only affects
	  VxWorks code

	* changed name of first argument of ACE_OS::sigprocmask() and
	  ACE_OS::thr_sigsetmask() from "signum" to "how" to better
	  represent what it really is.

Wed Oct 16 01:59:40 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Log_Record.cpp (print): added Luca's suggestion for checking
 	  if host_name == 0 for the ostream version of print(), as well.

	* Released version of ACE 4.0.32 for testing.

	* ace/Synch.h: Added many small fixes for HP/UX 10.x.  Thanks to
 	  Alan Stewart <axs2@osi.com> for providing these.

	* ace/OS.h: Added many new ACE_LACKS* and ACE_HAS* macros to
 	  support the MVS port.  Thanks to Chuck Gehr
 	  <gehr@sweng.stortek.com> for these.

Tue Oct 15 11:56:59 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.h: in a continuing effort to protect the ACE namespace,
 	  I've changed ace/OS.h around lines 127-137 so that "SYNCH" and
 	  "SYNCH_MUTEX", etc. are prefixed with "ACE_".  Thanks to Alan
 	  Stewart <axs2@osi.com> for suggesting this.

	* ace/Local_Tokens.h: Removed an unnecessary parameter name
	  that was unused.   Thanks to Stuart Powell <stuartp@in.ot.com.au>
	  for reporting this.

Tue Oct 15 17:03:37 1996  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

	* ace/ReactorEx.cpp (handle_events): Fixed a bug in handle_events
 	  so that the correct handlers get called when multiple handles
 	  become signaled simultaneously.  Thanks to Ari Erev
 	  <Ari_Erev@comverse.com> for pointing out this bug.  I also took
 	  this opportunity to fix a bug when handlers are removed during
 	  handle_events.

	* examples/Reactor/ReactorEx/test_remove_handler.cpp: Added a new
 	  application that tests how the ReactorEx services simultaneous
 	  events and removes handlers.  This example also illustrates the
 	  use of the new ACE_Events wrapper.  Check
 	  examples/Reactor/ReactorEx/README for more details.

Mon Oct 14 11:43:18 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* tests: Added a new version of run_tests.sh, which was
 	  contributed by Michael Rueger <mike@SYSCOMP.DE>.

	* examples/Logger/simple-server/Logging_Handler.cpp (handle_input)
 	  and examples/Logger/Acceptor-server/server_loggerd.cpp
 	  (handle_input): Changed from stderr to cerr to work around bugs
 	  with the C run-time libraries on Win32.  Thanks to Tilo Christ
 	  <christ@swl.fh-heilbronn.de> for suggesting this.

Mon Oct 14 11:09:42 1996  Prashant Jain  <pjain@merengue.cs.wustl.edu>

	* ace/Local_Name_Space_T.cpp (remap): Added processor specific
 	  stuff to remap(). The code was taken from the book "Win32
 	  Network Programming" by Ralph Davis (p.18) and takes care of
 	  cases specific to the 80x86 processor. The code ensures that the
 	  registers are set properly when we continue execution after an
 	  exception.

Sun Oct 13 21:18:38 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Log_Record.cpp (print): Added a test to make sure that the
 	  value returned from ctime_r != 0 (e.g., if time_stamp_ == -1) in
 	  order to avoid crashes.

	* examples/Logger/client/logging_app.cpp (main): Moved the
 	  construction of the ACE_Log_Record log_record object into the
 	  loop so that it will be recreated each time through.  If this
 	  isn't done, then we'll be continually "encoding" values into
 	  network byte order that have already been encoded and screwing
 	  things up on little-endian machines (such as Intel).  Thanks to
 	  Irfan and Tilo Christ <christ@swl.fh-heilbronn.de> for pointing
 	  me in the right direction on this.

	* ace/Log_Record.cpp: Changed the default constructor so that it
 	  gives default initializations to the data members.

	* examples/Logger/Acceptor-server/server_loggerd.cpp (handle_input): 
	  Fixed a couple of typos where 

	  Logging_Handler::handle_input (int)

	  should be:

	  Logging_Handler::handle_input (ACE_HANDLE)

	  and

	  size_t len;

	  should be:

	  ssize_t len;

	  Thanks to Irfan for finding these.

Sat Oct 12 08:48:23 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* Released a beta version of ACE 4.0.32 for testing.

	* ace/Log_Record.cpp: rewrote the code a bit to try and avoid
 	  problems on NT when host_name == 0.

	* ace/Log_Record.cpp: Changed the use of ACE_OS::ctime() to
 	  ACE_OS::ctime_r() to avoid problems that might arise when
 	  ACE_Log_Record::print() is called from multiple threads.

	* ace/Log_Record.cpp: Commented out calls to ACE_TRACE to avoid
 	  weird problems with circular dependencies.  Thanks to Luca
 	  Priorelli <lucapri@mbox.vol.it> for suggesting this.

	* build/SunOS5.5/examples/Makefile: Added the Logger directory to
 	  the list of targets that are build automatically by Make.

Fri Oct 11 17:13:03 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace: Fixed lots of small warnings revealed when using the
 	  Greenhills compiler on VxWorks.  Thanks to David Levine for
 	  this.

	* ace/Pipe.h: In Pipe.h, the return value of ACE_Pipe::close()
 	  isn't explicitly declared, so some compilers gag.  Thanks to
 	  David Levine for this.

Thu Oct 10 12:05:55 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Thread.cpp: Correctly wrapped the methods in the *.cpp file
 	  so that they are ignored if threads *aren't* supported.

	* ace/Service_Repository.cpp (remove): Added the ACE_MT in front
 	  of all the ACE_GUARD* macros that utilize ACE_Thread* locks in
 	  order to ensure that ACE compiles correctly on all non-MT
 	  platforms.

	* examples/Shared_Malloc/Malloc.cpp: Removed the special purpose
 	  class for PROCESS_MUTEX since ACE_Process_Mutex will now work
 	  for non-MT platforms.

	* examples/Misc/test_dump.cpp: Changed all occurrences of

	  cerr << "string " << this << endl;

	  to 

	  cerr << "string " << (u_long) this << endl;

	  to work around problems with IRIX 5.3.  Thanks to Tilo Christ
 	  <christ@swl.fh-heilbronn.de> for reporting this.

	* ace/config-linux.h: Added a // in front of a stray comment line.
  	  Thanks to Neil Cohen for pointing this out.

	* ace/config-hpux-10.x-g++.h: Added a new config file for HP/UX
 	  10.x which should fix some problems with templates by using the
 	  G++ compiler.  Thanks to <afarahat@CCGATE.HAC.COM> for
 	  contributing this.

Wed Oct  9 14:34:19 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS: Changed the logic of socket initialization, which has
 	  been moved out of ACE_SOCK and into ACE_OS.  This makes it
 	  possible to program more fully at the ACE_OS API (if such a
 	  crazy thing is really necessary ;-)).

	* examples/IPC_SAP/SOCK_SAP/C-in{client,server}.cpp: Fixed up the
 	  client and server apps so they will work on NT
	  (i.e., replaced the use of int with ACE_HANDLE).  Thanks to Joe
 	  DeAngelis <bytor@faxint.com> for suggesting this.

	* ace/Synch.h: Now that we've got support for POSIX semaphores on
 	  Solaris, then we'll use them (when they are supported...) as the
 	  implementation of ACE_Process_Semaphore rather than using the
 	  slower ACE_SV_Semaphore_Complex stuff...

	* ace/OS.{h,i}: Added David Levine's support for named POSIX
 	  semaphores.  If ACE_HAS_POSIX_SEM is defined, then ACE_Semaphore
 	  will construct a named POSIX semaphore if passed a non-null
 	  name, or an unamed POSIX semaphore if passed a null name.  This
 	  is a great addition because POSIX semaphores are more powerful
 	  and useful than the Solaris UI semaphores.  Unfortunately,
 	  Solaris 2.5 doesn't support them (yet).

Tue Oct  8 16:00:00 1996  Irfan Pyarali  <irfan@flamenco.cs.wustl.edu>

	* ace/OS: Integrated Irfan's encapsulation/emulation for Win32
 	  Events at the ACE_OS level. A new structure ACE_event_t was
 	  created to support Events on non-WIN32 platforms.  On WIN32
 	  platforms ACE_event_t is just a HANDLE.  On non-WIN32 platforms,
 	  ACE_event_t uses a combination of mutexes, condition variables,
 	  and counters to emulate Events. Both auto-reset and manual-reset
 	  events are supported.

	* ace/Synch: Integrated Irfan's encapsulation/emulation for Win32
 	  Events at the C++ wrappers level. There are three wrappers that
 	  were created: ACE_Event, ACE_Auto_Event, and ACE_Manual_Event.
  	  ACE_Event is a wrapper for the ACE_event_t structure. It
 	  provides functionality for signal, wait, pulse, and reset on an
 	  event. ACE_Event supports both auto-reset and manual-reset
 	  events. However, specializations of ACE_Event were created
 	  (ACE_Manual_Event and ACE_Auto_Event) to make it easier to use
 	  Events.

	* examples/Threads/test_manual_event.cpp: A test for manual-reset
 	  events. The test involves the creation and use of a barrier
 	  which uses an ACE_Manual_Event.

	* examples/Threads/test_auto_event.cpp: A test for auto-reset
 	  events. The test involves the use of an ACE_Auto_Event for
 	  signaling threads.

Tue Oct  8 15:45:01 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/DEV.cpp (ACE_DEV): Removed a stray call to
 	  ACE_IO_SAP::dump().  Thanks to Brad Flood <BFLOOD@tcs.lmco.com>
 	  for this fix.

	* ace/OS.i: Added ACE_HAS_CHARPTR_SOCKOPT for VxWorks.  Thanks to
 	  David Levine for this.

	* ace/Dump.cpp (instance): Added an ACE_MT() macro around the
 	  ACE_GUARD_RETURN macro so that this will compile correctly on
 	  non-threaded platforms.  Thanks to David Levine for this.

	* ace/OS.h: the declaration of ACE_OS::msgctl needs "struct
 	  msqid_ds" instead of just "msqid_ds" to compile with the
 	  Greenhills C++ compiler.  Thanks to David Levine for this...

	* ace/Local_Name_Space_T.h: Added #include "ace/Local_Name_Space.h" 
	  to avoid a problem during template generation.  Thanks to 
	  Chris Lahey for this fix.

	* ace/OS.i (getprotobynumber_r): Added a pair of fixes from Chris
 	  Lahey to get the ACE wrappers for the getprotoby*_r() methods to
 	  compile on AIX.

	* examples/Threads: Added two new examples (test_auto_event.cpp
 	  and test_manual_event.cpp) that exercise the new ACE_Event
 	  mechanisms.

	* ace/Synch: Integrated Irfan's encapsulation/emulation for Win32
 	  Events at the C++ wrappers level.

	* ace/OS: Integrated Irfan's encapsulation/emulation for Win32 
	  Events at the ACE_OS level.

Fri Oct  4 08:32:47 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.i: Added David Levine's new ACE_OS::mktemp() implementation.

Wed Oct  2 13:26:20 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/SV_Message_Queue.i: Changed the casts of (msgbuf *) to
	  (void *).

	* ace/OS.i: Added David Levine's implementation of inet_addr() for
 	  VxWorks.

	* ace/OS.i: Continued to merge together various parts of Win32 and
 	  UNIX to reduce redundancies.

Tue Oct  1 15:03:42 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.i: Added Chuck Gehr's new changes to ACE_OS::mutex_init()
 	  and ACE_OS::cond_init() to handle the MVS Pthreads madness.

	* ace/OS.i: Added zillions of #ifdefs for VXWORKS.  It's amazing
 	  these guys call themselves POSIX compliant -- lots of stuff is
 	  missing.  Thanks to David Levine for doing this!

	* ace/OS.cpp: Added David Levine's implementation of mktemp()
	  for platforms that don't support it.

	* ace/OS.h: Added a bunch of minor changes for VXWORKS.  In
 	  addition, started to factor out common #ifdefs to make the code
 	  easier to maintain.

	* ace/OS.h: Added a new macro for ACE_LACKS_UTSNAME, and factored
 	  this out for both VxWorks and Win32.

	* ace/Time_Value.h: Added support for 2 VXWORKSisms: (1) we need
 	  to #include sys/times.h rather than the standard UNIX sys/time.h
 	  and (2) we need to change const timeval & to const struct
 	  timeval & to keep the Greenhills compiler happy.  Thanks to
 	  David Levine for this.

	* ace/INET_Addr.cpp: Added support for the insane VXWORKS
 	  hostGetByName() function.  Yikes!  Thanks to David Levine for
 	  this.

	* ace/Memory_Pool.cpp: Added a new #define called ACE_LACKS_SBRK
 	  and ACE_LACKS_SYSV_SHMEM, which is enabled on Win32 and VxWorks.
  	  Thanks to David Levine for reporting this.

	* ace/OS.h: Added new macros that #define ETIME for platforms like
 	  VxWorks that don't support it, but do support ETIMEDOUT.

	* ace/OS.h: Added placeholder #defines for USYNC_PROCESS and
 	  USYNC_THREAD when !defined (ACE_HAS_THREADS).  Thanks to Neil
 	  Cohen for reporting this.

Tue Oct  1 00:42:35 1996  Douglas C. Schmidt  <schmidt@polka.cs.wustl.edu>

	* ace/Message_Block.cpp (size): Member base_ of ACE_Message_Block
	  was being set to the new memory pointer before the old contents
	  are saved in method size.  So the line 

	  this->base_ = buf;

	  was moved to a place some lines below.  Thanks to Marco Sommerau
 	  <sommerau@informatik.uni-stuttgart.de> for detecting this.

	* ace/Message_Queue.cpp: Changed the implementation of the
 	  enqueue_i() method so that FIFO order is maintained when
 	  messages of the same priority are inserted consecutively.
  	  Thanks to Jay Denkberg <jay_denkberg@comverse.com> for
 	  suggesting this.

Mon Sep 30 22:59:38 1996  Douglas C. Schmidt  <schmidt@polka.cs.wustl.edu>

	* ace/OS.i (thr_yield): Added a new macro ACE_HAS_YIELD_VOID_PTR
 	  to make pthread_yield work on MVS.  Thanks to Chuck Gehr
 	  <gehr@sweng.stortek.com> for this fix.

	* ace/OS: Added a new macro called ACE_HAS_TIMEZONE_GETTIMEOFDAY
 	  that handles problems on MVS.  Thanks to Chuck Gehr
 	  <gehr@sweng.stortek.com> for this fix.

Mon Sep 30 13:45:10 1996  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

	* ace/Local_Tokens.h: Updated some documentation in all the Token
	  files.

Mon Sep 30 18:01:12 1996  Prashant Jain  <pjain@merengue.cs.wustl.edu>

	* netsvcs/lib/: Renamed files Logger.{h,cpp} to
	  Logging_Strategy.{h,cpp} to avoid confusion with Server_Logging
	  and Client_Logging stuff. In addition, I modified the affected
	  files, including Makefile, README, and the config files in the
	  tests directory.

Sun Sep 29 12:47:37 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.h: Added Chuck Gehr <gehr@sweng.stortek.com> fixes for
 	  MVS to enable signals to work correctly.

	* ace/Time_Value.h: Added an extern "C" { } block around #include
 	  <pthreads.h> to solve a problem with Linux.  Thanks to Padhu
 	  Ramalingam <padhu@magicnet.net> for reporting this.

	* netsvcs/lib/Server_Logging_Handler.cpp: Changed the
 	  initialization of a static template object from ::request_count_
 	  (0L) to ::request_count_ = 0L.  Thanks to Gonzalo Diethelm
 	  <gonzo@ing.puc.cl> for reporting this.

	* ace/Remote_Tokens.h: Moved the inclusion of "Singleton.h" from
 	  Remote_Tokens.cpp to Remote_Tokens.h.  This should avoid
 	  template instantiation problems on some platforms (e.g., Irix
 	  6.2).

	* ace/config-irix6.2-sgic++.h: Changed ACE_HAS_SIGINFO to
 	  ACE_HAS_SIGINFO_T and added ACE_HAS_UCONTEXT_T.  Thanks to
 	  Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this.

	* ace/Token_Invariants.h: The ctor/dtor were private and the
 	  compiler would not allow a template of the class to be created.
  	  I switched them to public, but I wish there was a better way...
  	  Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting
 	  this.

	* ace/Synch_T.h: #include'd "ace/Event_Handler.h".  Thanks to
 	  Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this.

	* ace/Synch.h: The parameter name gives warnings when
 	  instantiating templates.  Thanks to Gonzalo Diethelm
 	  <gonzo@ing.puc.cl> for reporting this.

	* ace/Process: Changed the definition of the get_pid() method to
 	  getpid() to avoid a conflict with Irix.  Thanks to Gonzalo
 	  Diethelm <gonzo@ing.puc.cl> for reporting this.

	* ace/Log_Msg.cpp (log): Added another #elif !defined (ACE_WIN32)
 	  to handle logging for OS platforms that (1) aren't Win32 and (2)
 	  are versions of UNIX that don't support STREAM pipes.  Thanks to
 	  Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this.

	* ace/Acceptor.cpp (handle_signal): Erased the signum parameter
 	  name to avoid a nasty warning about arguments not used when
 	  instantiating templates.  Thanks to Gonzalo Diethelm
 	  <gonzo@ing.puc.cl> for reporting this.

	* ace/OS.h: Added the ACE_Export symbol to the definition of
 	  ACE_Str_Buf.  This makes it compile and link on NT.  Thanks to
 	  Prashant for noticing this (our favorite Win32ism...).

	* ace/Thread.h (ACE_Thread): Removed a default argument for one of
 	  the ACE_Thread::join() wrappers so this won't be ambiguous with
 	  the other join() wrapper.

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

Sun Sep 29 16:12:01 1996  Prashant Jain  <pjain@merengue.cs.wustl.edu>

	* netsvcs/lib/: Renamed the project file for Win32 from lib.mdp to
 	  netsvcs.mdp. Also the original project file did not include some
 	  files such as Naming_Handler.cpp and Server_Logging_Handler.cpp
 	  and I fixed that. Finally removed two files System_Time.{h,cpp}
 	  which are already present in ace/.

Sat Sep 28 16:34:56 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS: Added a new overloaded select() method that takes a
 	  const ACE_Time_Value &.  This is useful for situations where you
 	  are passing in ACE_Time_Value::zero.

Fri Sep 27 16:20:46 1996  Douglas C. Schmidt  <schmidt@polka.cs.wustl.edu>

	* ace/ACE: Added a fix for the fact that VxWork's write() call
	  doesn't take a const char *.

	* ace: Started adding support for VxWorks and GreenHills compiler,
 	  e.g., added the config-vxwork-ghs-1.8.h file.  Thanks to David
 	  Levine <levine@cs.wustl.edu> for getting this rolling!

Thu Sep 26 00:15:46 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Timer_Queue: Changed the public interface methods to be
 	  virtual in order to make it possible to override them in
 	  subclasses.  This makes it feasible to implement different types
 	  of Timers.

	* ace/OS: Added a wrapper for the strspn() string call.  Thanks to
 	  Irfan for noticing this omission.

	* ace/Synch_T.cpp (wait): Changed the line:

	  return ACE_OS::cond_wait (&this->cond_, this->mutex_);

	  to

	  return ACE_OS::cond_wait (&this->cond_, &this->mutex_.lock_);

	  Thanks to Dieter Quehl <dietrich.quehl@med-iss1.med.siemens.de>
 	  for noticing this.

	* ace/config-sunos5.4-g++.h: Removed the #define for
 	  ACE_HAS_BROKEN_RANDR and replaced the ACE_HAS_SVR4_SIGNAL_T with
 	  ACE_HAS_CONSISTENT_SIGNAL_PROTOTYPES since it looks like the
 	  latest gcc release (2.7.2) fixes this in their own header files.

Sat Sep 21 10:45:43 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.h: Added a new #define called ACE_HAS_BROKEN_MSG_H to the
 	  config-osf1-3.2.h file and used it in OS.h to work around
 	  problems with <msg.h> prototypes on that platform.

Fri Sep 20 00:15:29 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

        * Released version 4.0.31 for testing.

	* ace/Pipe.cpp: Initialize handles_ to ACE_INVALID_HANDLE in
 	  default constructor.  Thanks to Tim Harrison for pointing this
 	  out.

        * ace: Copied in new versions of ace.{mak,mdp} for Win32.

        * ace: Added TTY_IO.cpp to the Makefile.

	* ace/config-win32-msvc[24].0.h: Updated the config file so that
 	  it *doesn't* #define ACE_HAS_STRBUF_T since this type clearly
 	  isn't available on Win32!

	* ace: Modified all of OS.i and config-*.h files so that they
 	  would be consisten with respect to handling the size_t and int
 	  differences in socket implementations.  Thanks to Chuck Gehr
 	  <gehr@sweng.stortek.com> for helping with this for AIX.

	* ace/ACE.h (ACE): Added a new method called max_handles() that
 	  returns the maximum number of open handles currently supported
 	  by the process.

	* examples/Reactor/Misc/signal_tester.cpp: Revised the test to
 	  utilize the new idioms for programming with signals.

	* ace/OS.h: added a new #define called ACE_DEV_NULL that defaults
 	  to "/dev/null" on UNIX and "nul" on NT.  Thanks to David Trumble
 	  <trumble@steosf.nio.dec.com> for reporting this fix.

	* ace/Log_Msg.cpp: Added some checks to make sure that we don't
 	  try to strdup() if we are passed a NULL pointer.  Thanks to Luca
 	  for suggesting this.

	* ace/OS: Move ACE_Str_Buf into OS.{h,i} and remove the Str_Buf.h
 	  file.

	* Makefile: Added the "performance-tests" directory to the list of
 	  directories we build when making ACE.

	* ace: Moved the definition of strbuf from Str_Buf.h into OS.h.
  	  Thanks to Irfan for recommending this.

	* ace/Makefile: Added some additional sed magic on the
 	  Svc_Conf_y.cpp file in order to remove the very last warnings
 	  from MSVC++!

Thu Sep 19 00:00:17 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Service_Config.cpp (open): Only initialize the logger to use
 	  STDERR if the user hasn't already set the ACE_Log_Msg::flags().
  	  Thanks to Tom Leith <trl@icon-stl.net> for suggesting this.

	* ace/OS: Removed all traces of the ACE_HAS_INT_SOCKNAME and
 	  ACE_HAS_LENPTR_SOCKOPT since Chris Lahey's new fixes for AIX
 	  obviate the need for these.

	* ace/OS.i: Only #include <rpc/rpc.h> if the platform has RPC!
  	  Thanks to Chuck Gehr <gehr@sweng.stortek.com> for suggesting
 	  this.

	* ace: Removed all uses of ACE_HAS_SETOWN and replaced them with
 	  explicit tests for F_SETOWN and FASYNC.  This is more portable.
  	  Thanks to Chuck Gehr <gehr@sweng.stortek.com> for suggesting
 	  this.

	* ace/OS: Added a new #define called ACE_HAS_SIZET_SOCKET_LEN to
 	  handle platforms where the length parameter of bind(),
 	  connect(), accept(), etc. uses size_t rather than int.  This
 	  helps to get ACE working on MVS.  Thanks to Chuck Gehr
 	  <gehr@sweng.stortek.com> for suggesting this.

	* ace/OS: Added Chris Lahey's fixes that make the
 	  getprotoby{name,number}_r() functions work for AIX.

	* ace: Changed the ACE_HAS_STRUCT_HOSTENT_DATA to
 	  ACE_HAS_STRUCT_NETDB_DATA because we use a single symbol to
 	  refer to all of the odd netdb.h stuff that AIX has...

	* ace: Changed all uses of:

	  iovec *iovp = (iovec *) alloca (total_tuples * sizeof *iovp);

	  to

	  iovec *iovp = (iovec *) alloca (total_tuples * sizeof (iovec));

	  to keep the AIX compiler from complaining (falsely) about using
 	  iovp before it is initialized.  Thanks to Chris Lahey for
 	  reporting this.

	* ace/OS.h: Added Chris Lahey's changes that handle AIX's
 	  _XOPEN_EXTENDED_SOURCE features without polluting all the socket
 	  implementations!

	* ace/Thread.cpp (spawn_n): Removed an unreferenced local variable
 	  so that the Win32 compiler doesn't complain.

	* ace/OS.h: Added the definition for strbuf{} for NT.

	* ace: Removed the msg_hack.h file since it had OSF and DEC
 	  copyright info in it.  Replaced this with Antonio Tortorici's
 	  <antonio@rh0011.roma.tlsoft.it> clever use of _KERNEL and the
 	  new ACE_LACKS_SYSV_MSQ_PROTOS.

	* ace/INET_Addr.h: Updated the documentation to indicate more
 	  clearly the use of getservbyname().

	* ace/OS.cpp (thr_create): Added basic hooks to support the use of
 	  AfxBeginThread on Win32.  This is necessary to allow ACE to work
 	  seemlessly with MFC applications.  Added an THR_USE_AFX flag
 	  that can be "or'd" in with the other thread flags in calls to
 	  ACE_OS::thr_create().  If this flag is enabled *and* if we are
 	  compiling with ACE_HAS_MFC enabled, then AfxBeginThread() is
 	  called rather than _beginthreadex().

	* ace/INET_Addr.h (set): Fixed a typo in the documentation for
 	  set() (the order of "host:port" was backwards...).  Thanks to
 	  Brad Flood <BFLOOD@tcs.lmco.com> for reporting this.
 
Wed Sep 18 00:36:01 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/SOCK_IO.cpp: Added a new recv() method that allows a client
 	  to read from a socket without having to provide a buffer to
 	  read.  This method determines how much data is in the socket,
 	  allocates a buffer of this size, reads in the data, and returns
 	  the number of bytes read.  The caller is responsible for
 	  deleting the memory.  Thanks to Luca Priorelli
 	  <lucapri@mbox.vol.it> for suggesting this.

	* ace/OS.h: Added a special #ifdef for IRIX 6.2 threads so that
 	  THR_BOUND and THR_SCOPE_SYSTEM are different.  Thanks to Gonzalo
 	  Diethelm <gonzo@ing.puc.cl> for reporting this.

	* ace/Message_Block.i (msg_class): Added a new "class" of messages
 	  to ACE_Message_Block: MB_USER.  This is useful for writing
 	  extensible applications a la Microslush Windows MSG stuff...

Tue Sep 17 16:38:44 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Message_Block: Changed the signature of the
 	  ACE_Message_Block constructors (and init()) so that they take
 	  const char * rather than char *.  In addition, changed the
 	  definition of one of the constructors (and init()) so that it
 	  takes a size field in addition to the buffer.

	* ace/Message_Block.cpp (size): Fixed a bug in the
 	  ACE_Message_Block::size() method -- we were failing to deal with
 	  allocators and ownership correctly during a resize.  Thanks to
 	  Amos Shapira <amos_shapira@mail.icomverse.com> for reporting
 	  this.

	* ace/Naming_Context.cpp: Removed the source of yet another
 	  warning about "inconsistent dll linkage.  dllexport assumed."

	* ace/Mem_Map.cpp (map_it): Added a cast to size_t (file_len)
 	  because by this time we know that file_len >= 0.  This avoids
 	  yet another warning on WinNT!

	* ace/Reactor.h: Fixed the remaining warnings about
 	  "signed/unsigned mismatch" in Win32 by changing the type of
 	  cur_size_ from size_t to ssize_t.

	* ace/Log_Msg.cpp: Modified the code so that on NT we use
 	  ACE_SPIPE_Msg rather than ACE_FIFO_Send_Msg.  Thanks to Luca
 	  Priorelli <lucapri@mbox.vol.it> for suggesting this.

	* ace/OS.i: Implemented the and put[p]msg() wrappers by being
 	  smart about allocating and copying data.

	* ace/TTY_IO.cpp (control): There was one too many end parentheses
 	  on line 192 of TTY_IO.cpp.  Thanks to Dave Trumble
 	  <trumble@steosf.nio.dec.com> for reporting this fix.

	* ace/Log_Msg.cpp (local_host): Fixed the use of program_name_ and
	  local_host_ so that they strdup() the values passed by the
	  users, rather than copying pointers.  This avoids problems if
	  the user doesn't pass in static memory.  Thanks to Luca
	  Priorelli <lucapri@mbox.vol.it> for reporting this.  Somehow
	  this change got lost and I've reapplied it...

	* ace/Log_Record.cpp (round_up): Added an extra + 1 to the length
 	  since otherwise the final '\0' gets lots if len is a multiple of
 	  8.  Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting
 	  this.  Somehow this change got lost and I've reapplied it.

	* ace/Memory_Pool.h: removed #if defined (ACE_HAS_SIGINFO_T) logic
 	  from both handle_signal() definitions (ACE_Shared_Memory_Pool
 	  and ACE_MMAP_Memory_Pool).  Thanks to Chris Lahey for fixing
 	  this.

	* ace/OS.h: Moved the define of SA_RESTART below the #include for
 	  signal.h.  Otherwise SA_RESTART will always be defined by OS.h,
 	  since SA_RESTART is defined on AIX in signal.h.  Thanks to Chris
 	  Lahey for fixing this.

	* ace/OS.h: Added some new #pragmas to suppress harmless warnings
 	  for the MSVC++ compiler.

Tue Sep 17 13:20:53 1996  Prashant Jain  <pjain@merengue.cs.wustl.edu>

	* ace/Local_Name_Space_T.cpp: Modified ACE_Local_Name_Space::
	  create_manager () so that all three naming scopes use the
	  database variable defined in Name Options. This allows us to
	  specify different names for databases for all three naming
	  contexts. However, it is imporant to note that this can lead to
	  potential problems where, for example, a process may use the
	  same name for PROC_LOCAL database as an already existing
	  NET_LOCAL database.

Mon Sep 16 01:31:21 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* examples/Logger/simple-server/Logging_Handler: get_handle(),
 	  handle_input(), and handle_close() want the right types
	  (ACE_HANDLE instead of int).  Thanks to Luca Priorelli
 	  <lucapri@mbox.vol.it> for reporting these.

	* examples/Logger/simple-server/Logging_Acceptor.cpp: Fixed a typo
 	  (Log_Mskg.h should be Log_Msg.h of course...).  In addition,
 	  changed the use of -1 to ACE_INVALID_HANDLE.  Thanks to Luca
 	  Priorelli <lucapri@mbox.vol.it> for reporting these.


	* ace: Changed all uses of ACE_HAS_ACE_INLINED_OSCALLS to
 	  ACE_HAS_INLINED_OSCALLS.  This was a vestiage of a global
 	  replace gone amok.  Thanks to Alan Stweart <Axs2@osi.com> for
 	  reporting this!

	* ace/Log_Msg.cpp (open): Added a check for the OSTREAM flag in
 	  the ACE logger.  Thanks to Rick Orr
 	  <rorr@costello.den.csci.csc.com> for noticing this.

        * Released version 4.0.30 for testing.

	* netsvcs/clients/Naming/Dump_Restore/Dump_Restore.cpp
	  (Dump_Restore): Deleted an extra "return 0;" within a
	  constructor (duh...).

	* examples/Threads/test_process_{semaphore,mutex}.cpp (main):
 	  Fixed some annoying G++ compiler bug related problems.  We need
 	  to use old-style C casts to prevent ambiguous parsing.

	* examples/ASX/Event_Server/Transceiver/transceiver: Rewrote this
 	  example to illustrate how to use the ACE_Connector and
 	  ACE_Svc_Handler.

	* examples/ASX/Event_Server/Transceiver/transceiver: Finally clued
 	  in and realized that it is just not suitable to implement the
 	  event server transceiver with separate threads for input and
 	  output.  It is simply to non-portable to get these shut down
 	  gracefully.  I think John Ousterhout was right -- threads are
 	  evil!
	  
	* examples/ASX/Event_Server: Merged the Consumer/Supplier
 	  directories into a single Transceiver directory to reflect the
 	  fact that the Consumer and Supplier were completely symmetrical!

	* ace/Module.cpp (close): Don't delete the Tasks in a Module if
 	  there are still threads running in them.  Otherwise we'll end up
 	  with a big mess.

Mon Sep 16 15:50:45 1996  Prashant Jain  <pjain@merengue.cs.wustl.edu>

	* performance-tests/Misc/test_naming.cpp: Added a new test to the
	  performance-tests directory called test_naming which simply does
	  performance testing on Naming Service. The test runs both the
	  SYNC and the NO-SYNC version of Naming Service.

Mon Sep 16 15:22:52 1996  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

	* ace/Proactor.cpp (initiate): Added a check for
	  ERROR_NETNAME_DELETED after ReadFile/WriteFile.  Now the
 	  initiating handler is immediately dispatched for EOF *and*
 	  closed connections.  Thanks to Luca Priorelli
 	  <lucapri@mbox.vol.it> for suggesting this change.

Sun Sep 15 00:55:59 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* Fixed all uses of ACE_Service_Config::end_event_loop() and
 	  ACE_Service_Config::run_event_loop() to be
 	  ACE_Service_Config::end_reactor_event_loop() and
 	  ACE_Service_Config::run_reactor_event_loop() since we now have
 	  to consider the other event loops (e.g., Proactor and ReactorEx)
 	  and it doesn't seem right to relegate those to 2nd class status.

	* ace: Finally got fed up with all the #ifdefs required to deal
 	  with extended signals and just changed the
 	  ACE_Event_Handler::handle_signal() method to always use the
 	  extended signal interface.  Fortunately, we can use default
 	  values to hid this from callers (though you may need to change
 	  your class definitions if you were assuming the
 	  handle_signal(int) interface.

	* ace/Memory_Pool.h: Changed all the methods of the various
 	  Memory_Pool classes to be virtual so that subclasses can
 	  selectively override them.  This shouldn't affect performance
 	  since all existing use cases work directly with the "derived"
 	  classes themselves, so there shouldn't be any overhead since the
 	  compiler can use direct calls rather than virtual function
 	  calls.

	* ace/OS.cpp (thr_create): Changed the call to CreateThread() to
 	  _beginthreadex() and the call to ExitThread() to _endthreadex()
 	  for Win32 in order to make ACE threads work correctly with
 	  Win32.  Thanks to James Mansion <james@wgold.demon.co.uk> for
 	  recommending this.

	* ace/ACE: Added two new static functions: read_adapter() and
 	  register_stdin_handler().  These are useful when writing code
 	  that must demultiplexing ACE_STDIN on both Win32 and UNIX.  This
 	  works around Win32 limitations that don't allow us to select()
 	  on non-sockets (such as ACE_STDIN).

	* examples/ASX/CCM_App/SC_Server.cpp: Updated this
 	  test so that it should now work correctly on Win32, where it
 	  isn't possible to select() on STDIN...

	* ace/Synch_T: Added a new class to ACE called "ACE_Test_and_Set."
  	  As this name implies, this class implements an atomic ``test and
 	  set'' abstraction.  This has all sorts of useful implications,
 	  particularly because it is a template that can be paramaterized
 	  by the type of LOCK (e.g., ACE_Null_Mutex, ACE_Thread_Mutex,
 	  etc.) and the type of TYPE (e.g., int, double, sig_atomic_t,
 	  etc.).  In addition, because this "is-a" ACE_Event_Handler it
 	  instances can be registered with the Reactor and used to shut
 	  down event hoops gracefully upon receipt of certain signals
	  (e.g., SIGINT).  In fact, I've redone many of the example
	  applications (e.g., ./examples/Logger/server/server_loggerd.cpp)
	  to illustrate how this works.

Sun Sep 15 20:40:17 1996  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

	* ace/ReactorEx.cpp (notify): I've redesigned this code.
  	  Previously, ReactorEx was explicitly managing a handle that it
 	  kept in handles_[0].  handles_[0] was used to implement
 	  ReactorEx::notify, which allowed other threads to wake up the
 	  thread waiting in ReactorEx::handle_events.  Now ReactorEx has
 	  an Event_Handler (ReactorEx_Notify) that is registered in the
 	  constructor of ReactorEx.  This allows us to treat events from
 	  handles_[0] just like every other event (i.e. by dispatching to
 	  handles_[0]->handle_signal). One of the results of this change
 	  is that code in remove_handler() is simplified a bit.

Sun Sep 15 17:56:52 1996  Prashant Jain  <pjain@merengue.cs.wustl.edu>

	* ace/Naming_Context.cpp: Added a new flag to the constructor and
	  open() method of ACE_Naming_Context that allows us to specify
	  which Memory_Pool to use when creating ACE_Local_Name_Space
	  (that is choose between ACE_MMap_Memory_Pool and
	  ACE_Lite_MMap_Memory_Pool). 

	* ace/Memory_Pool.cpp: Added a new class called
 	  ACE_Lite_MMap_Memory_Pool which subclasses ACE_MMap_Memory_Pool
 	  and overrides the sync method so that it is a no-op.

	* ace/Local_Name_Space.cpp: Made some siginificant changes in
	  ACE_Local_Name_Space. Here is what the problem was:
	  ACE_Name_Space_Map (which is an ACE_Map_Manager) used an
	  ACE_RW_Process_Mutex for synchronization. However, since the Map
	  was kept in shared memory and was shared by all the processes,
	  it got instantiated only by the first process which came
	  along. Therefore, only the first process got around to creating
	  and initializing the lock. 

	  In fixing the problem, we made some other changes to
	  ACE_Local_Name_Space and ACE_Name_Space_Map.  Both classes are
	  now template classes. ACE_Local_Name_Space needs to be
	  parameterized with a Memory_Pool (thus giving us a hook to
	  implement the NO-SYNC option) as well as a LOCK.
	  ACE_Name_Space_Map needs to be parameterized by an ALLOCATOR
	  which is created by ACE_Local_Name_Space. Note that the reason
	  we need to parameterize ACE_Name_Space_Map is so that we can
	  pass an ACE_Allocator_Adapter (which subclasses from
	  ACE_Allocator) with every method. It is not possible to pass an
	  ACE_Allocator since the ::remap() method relies on an
	  allocator() method defined on the ALLOCATOR that is passed in
	  (and ACE_Allocator does not define an allocator() method). 

	  The purpose of the class ACE_Name_Space_Map still remains the
	  same. It IS_A Map_Manager and provides the hook to set the
	  allocator to the process specific one. However, none of its
	  methods acquire any locks. For that reason, the Map_Manager is
	  parameterized with the Null_Mutex. All synchronization takes
	  place inside ACE_Local_Name_Space. ACE_Naming_Context
	  instantiates ACE_Local_Name_Space (depending upon the scope) and
	  by default parameterizes it with ACE_MMap_Memory_Pool and
	  ACE_RW_Process_Mutex. 

	  Also made some more fixes to ACE_Local_Name_Space. In
	  create_manager(), after we create the allocator, we now check to
	  see if the backing store was created successfully and if not, we
	  return -1. 

Sat Sep 14 00:00:31 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* examples/Logger: Renamed the original server directory to
 	  "simple-server" and added a new directory called
 	  "Acceptor-server" which implements the Logger using the
 	  ACE_Acceptor.  Note that almost all of the implementation code
 	  disappears!

	* ace/Local_Name_Server_T.cpp: Removed the name_server_map_ array
 	  and replaced it with the ACE_NAME_SERVER_MAP #define, which is
 	  now contained in OS.h.

	* ace/Malloc.h: Added "virtual ... = 0" to the bind() and
 	  trybind() methods of the ACE_Allocator since they should be pure
 	  virtual functions...

	* ace/Synch{_T}: Separated out the wait (ACE_Time_Value *) and
 	  wait (void) methods in order to optimize the call sequence for
 	  the common case when there is no timeout.

	* ace/Synch: Added a new wait(ACE_Thread_Mutex &) method to
 	  ACE_Condition_Thread_Mutex so that we are consistent with the
 	  templated ACE_Condition_Mutex.

	* include/makeinclude: Changed uses of -pic to -PIC because ACE is
 	  now creating more than 2082 symbols.  It's probably time to
 	  split up the library...

	* ace/DEV_IO: Moved the ACE_DEV_Addr instance from ACE_DEV_IO into
 	  ACE_DEV so that it will be available for the ACE_DEV_Connector.
  	  This fixes a bug that prevented us from using the ACE_Connector
 	  in conjunction with the ACE_DEV_* classes.  Thanks to Karlheinz
 	  for clarifying what had to occur.
    
Fri Sep 13 00:16:32 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.h: Changed the order of #includes so that <assert.h>
 	  comes before <sys/stat.h>.  This fixes some bugs with the
 	  Siemens SVR4 C++.  Thanks to Antonio Tortorici
 	  <antonio@rh0011.roma.tlsoft.it> for this fix

	* ace/ACE.cpp (handle_timed_complete): Added yet another weird
 	  hack to deal with the insanity that is TLI...

	* ace/Synch.cpp: Replaced all uses of ACE_Thread_Mutex_Guard with
 	  ACE_GUARD macros in order to avoid problems when mutexes fail.

	* ace/OS.h: Changed the definition of the ACE_*GUARD macros so
 	  that they are always enabled, even when we turn off ACE_MT_SAFE.
  	  This avoids a nasty semantic problem for components that use
 	  ACE_Process_Mutex.  Thanks to Avraham Nash
 	  <Avraham_Nash@praxisint.com> for reporting this problem.

	* ace/OS: Removed ACE_OS::fork_exec() since its functionality has
 	  been subsumed by ACE_Process.

	* ace/Thread_Manager: Added a new thread_descriptor_i() method
 	  that *doesn't* grab the lock in order to avoid deadlocks.

	* include/makeinclude/platform_sunos5_sunc++.GNU (CXX): had to add
 	  the -pta option so that we achieve template closure in ACE.

	* include/makeinclude: Added -lthread to the
 	  platform_sunos5_sunc++.GNU file.  I don't know how this slipped
 	  through the cracks!

	* ace/{DEV_IO,FILE_IO,SOCK_IO,SPIPE_Stream}: Fixed a braino with
 	  alloca where I was failing to multiply by sizeof (iovec).  Isn't
 	  C great? ...  Thanks to Chuck Gehr <gehr@sweng.stortek.com> for
 	  reporting this.

	* ace/SOCK_Dgram_Mcast.cpp: Added two changes to the ACE multicast
 	  code in order to get it to work on Win32.  The first change is
 	  to put the IP_ADD_MEMBERSHIP setsockopt() call *after* the
 	  bind() (in shared_open()).  The second is to convert the
 	  ACE_INET_Addr::get_ip_address() from host byte order into
 	  network byte order.  Thanks to Todd L. Montgomery
 	  <tmont@cerc.wvu.edu> and Steve Weismuller
 	  <spweismu@rsoc.rockwell.com> for helping with this.

	* examples/Threads/test_barrier2.cpp: Incorporated Karlheinz's
	  new ACE_Barrier test program.

	* ace/Synch.h: Added Karlheinz's ACE_Null_Barrier class.

Fri Sep 13 00:30:50 1996  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

	* tests/{Tokens_Test,Time_Service_Test}.cpp: Updated tests to use
 	  ACE_Process instead of ACE_OS::fork_exec.

	* ace/Process.cpp: Added a new ACE_Process abstraction that is a
 	  Portable encapsulation for creating new processes.  It allows
 	  assignment of STDIN, STDOUT, and STDERR of the new process.  On
 	  UNIX, ACE_Process uses fork and exec.  On Win32, it uses
 	  CreateProcess.  Since we can set the standard handles, we can
 	  mimic UNIX pipes on Win32 by building chains of processes.  This
 	  class should be used instead ACE_OS::fork_exec.

	* examples/OS/Process/process.cpp (main): Added new example
 	  application to show how to use ACE_Process.

Thu Sep 12 00:55:25 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/DEV_IO: Added methods get_local_addr() and get_remote_addr()
 	  so that ACE_Connector will work correctly.  Thanks to Brad Flood
 	  <BFLOOD@tcs.lmco.com> for reporting this.

	* ace/Thread_Manager.cpp (thr_self): Added a fix to solve the
 	  problem that Win32 GetCurrentThread() returns a pseudo-handle
 	  rather than a real handle.  Now, we just look things up using
 	  the thread id rather than the thread handle.  Thanks to Luca
 	  Priorelli" <lucapri@mbox.vol.it> for clarifying this.

	* ace/Proactor.cpp (initiate): Fixed an incorrect set of return
 	  values -- they were reversed.  Thanks to Brad Flood
 	  <BFLOOD@tcs.lmco.com> for reporting this.

	* ace/OS.i (thr_cmp): Added a check for
 	  !defined(ACE_HAS_SETKIND_NP) to avoid a problem with OSF/1.
  	  Thanks to Martin Schoeckle <schoeckle@ike.uni-stuttgart.de> for
 	  reporting this.

	* examples/IPC_SAP/DEV_SAP: Updated these examples to use the new
 	  ACE_TTY_IO classes.

	* ace: Moved the TTY_IO code from the
 	  examples/IPC_SAP/DEV_SAP/{reader,writer} directories into the
 	  files TTY_IO.{h,cpp} in the main part of ACE and integrated Brad
 	  Flood's <BFLOOD@tcs.lmco.com> changes for Win32.

	* ace/DEV_IO.i: Changed the mapping of send_n() and recv_n()
 	  methods to use write_n() and read_n() respectively so they will
 	  work on NT.  Thanks to Brad Flood <BFLOOD@tcs.lmco.com> for
 	  reporting this.

	* ace/Thread_Manager.h: Implemented a non-synchronized version of
 	  the lookup function for the <hthread_descriptor>.  This version
 	  assumes that the lock is help.  We need this to avoid
 	  intra-class method deadlock on systems (such as Solaris) that
 	  lack recursive mutexes.

	* ace/Log_Msg.cpp (ACE_Log_Msg): made sure to initialize
 	  ACE_Log_Msg::thr_handle_ to 0.  I'm not sure how this got
 	  changed...  Thanks to Luca Priorelli <lucapri@mbox.vol.it> for
 	  reporting this.

	* examples/Reactor/ReactorEx/test_reactorEx.cpp
 	  (register_thread_exit_hook): Changed hthread_t to ACE_hthread_t.
  	  Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting
 	  this.

	* apps/Gateway/Gateway/Channel.h: Due to inconsistencies between
 	  the semantics of sockets and TLI with respect to establishing
 	  non-blocking connections it's not a good idea to use TLI in
 	  conjunction with select().  Therefore, I've #if 0'd out the use
 	  of TLI in the Gateway application.

Wed Sep 11 00:25:38 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/ACE.cpp (handle_timed_complete): Fixed a typo that was
 	  failing to set n = ACE::recv(...).  In addition, rethought how
 	  we figure out if a connection completes for the nth time...

	* ace/TLI.cpp (open): Modified the implementation of open() so
 	  that if oflag == 0 it is given an initial value of O_RDWR.
  	  Otherwise we'll get a "badflags" t_errno.

	* ace/Connector.h (connect): Modified connect() so that the
 	  default value of the flags parameter is O_RDWR.  This is
 	  necessary to make TLI_Connector::connect() work correctly by
 	  default.

	* examples/Logger: Updated the example logger client and server to
 	  illustrate more clearly how things like the Singleton Reactor
 	  and the ACE_Reactor timer mechanism work.  Thanks to Joe
 	  DeAngelis <bytor@faxint.com> for suggesting this.

	* ace/Pipe: Added a new constructor that makes it possible to
 	  initialize the <ACE_Pipe> from the <read> and <write> handles.
  	  Thanks to Stevan Warwick (sjw@aesthetic.com) for suggesting
 	  this.

	* config-irix5.3-sgic++.h: Added #define for ACE_NEEDS_SYSTIME_H.
  	  Thanks to Stevan Warwick (sjw@aesthetic.com) for reporting this.

	* examples/Logger/server/Client_Acceptor: Fixed some stray
 	  mis-uses of int that should have been ACE_HANDLE.  Thanks to
 	  Luca Priorelli" <lucapri@mbox.vol.it> for reporting this.

	* ace/{ACE,Log_Msg}.cpp: Added fixes for hexdump().  Thanks to
 	  Luca Priorelli" <lucapri@mbox.vol.it> for supplying these.

	* ace/Reactor.cpp (ACE_Reactor): Fixed a typo: "this->max_handlep1
 	  ()" should be "this->handler_rep_.max_handlep1 ()".  Thanks to
	  Scott Shupe <shupes@mitre.org> for reporting this.

	* apps/Orbix-Examples/Event_Comm: Added a bunch of changes to make
 	  this application compile with Orbix 2.0.  Thanks to Mike
 	  O'Malley <momalley@caesun16.msd.ray.com> for the fixes.

	* ace/OS.cpp (thr_create): Added yet another fix for the IRIX 6.2
 	  pthreads implementation.  Thanks to Gonzalo Diethelm
 	  <gonzo@ing.puc.cl> for reporting this.

	* ace/config-irix6.2-sgic++.h: Changed ACE_HAS_IRIX53_GETTIMEOFDAY
 	  to ACE_HAS_IRIX_GETTIMEOFDAY because this also seems to be the
 	  case for IRIX 6.2...  Thanks to Gonzalo Diethelm
 	  <gonzo@ing.puc.cl> for reporting this.

	* ace/TLI_{Connector,Acceptor}.cpp: Added tests against NULL
 	  pointers to avoid segmentation faults when the TLI
 	  implementation doesn't allocate memory for the udata and opt
 	  fields of netbuf structures.

	* ace/Mem_Map.i (ACE_Mem_Map): Added an accessor so that callers
 	  can get the name of the filename that is being used as the
 	  backing store.  Thanks to the James Mansion
 	  <james@wgold.demon.co.uk> for recommending this.

Tue Sep 10 00:26:52 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/OS.cpp (thr_create): Modified the thr_create()
 	  implementation for Win32 so that if the caller doesn't care
 	  about this value we can avoid a HANDLE leak.  Thanks to the
 	  James Mansion <james@wgold.demon.co.uk> for recommending this.

	* ace/Thread.cpp (ACE_Thread): Moved both definitions of spawn_n()
 	  into the Thread.cpp since they have loops and don't benefit from
 	  being inlined.  

	* ace/Svc_Handler.h: Moved operator delete() into the public part
 	  of the class in order to make various compilers happy...

	* ace/OS.i (ACE_OS): Fixed the #define that selects the (union
 	  wait *) alternative of wait().  This original was protected by
 	  ACE_LACKS_POSIX_PROTO, but it should be ACE_HAS_UNION_WAIT.

	* performance-tests: Created a new directory that will contain all
 	  of the ACE performance tests.  Move the Synch-Benchmarks and the
 	  TTCP tests from ./apps into here, and also moved the
 	  test_mutex.cpp and test_singleton.cpp files from
 	  ./examples/{Threads,Misc}, respectively.  Thanks to Tim Harrison
 	  for this suggestion.
  
	* ace/OS.i (ACE_OS): in WIN32 closesocket() returns 0 if call is
 	  OK, so I changed the return value to be the other way around.
  	  Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting
 	  this.

	* ace: Changed the ACE_NO_POSIX_PROTO #define to something more
 	  meaningful: ACE_LACKS_POSIX_PROTO.  Thanks to Jonathan Biggar
 	  <jon@sems.com> for suggesting this.

	* ace/config-sunos4-g++.h: Added the #define ACE_NEEDS_SYSTIME_H.
  	  Thanks to Alexandre Karev <akg@na47sun05.cern.ch> for reporting
 	  this.

	* ace/OS: Fixed a bunch of pthreads portability problems that
 	  showed up on OSF/1 4.0.  Also added support for asctime_r() and
 	  ctime_r() for OSF/1 4.0.  Thanks to Dave Trumble
 	  <trumble@steosf.nio.dec.com> for reporting these fixes.

	* ace/Synch_T.cpp (ACE_TSS_Read_Guard): Removed a stray "new" that
 	  was causing problems for the ACE_NEW macro.  Thanks to Dave
 	  Trumble <trumble@steosf.nio.dec.com> for reporting this.

        * ace/Local_Tokens.h: Fixed a broken use of "friend", which was
 	  missing the keyword "class."  Thanks to Dave Trumble
 	  <trumble@steosf.nio.dec.com> for reporting this.

	* ace/config-osf1-4.0.h: Included Dave Trumble's
	  <trumble@steosf.nio.dec.com> config file for OSF/1 4.0.

	* include/makeinclude/platform_osf1_4.0.GNU: Included Dave
 	  Trumble's <trumble@steosf.nio.dec.com> platform macros file for
 	  OSF/1 4.0.  Also renamed platform_osf1.GNU to
 	  platform_osf1_3.2.GNU to deal with the new version.

	* ace/Proactor: There wasn't a way to destroy an
 	  ACE_Overlapped_File object without closing the ACE_HANDLE
 	  attached to it.  Therefore, I added a flag that keeps track of
 	  whether we have to delete this or not.  Thanks to Amos Shapira
 	  <amos_shapira@mail.icomverse.com> for suggesting this.

	* examples/Threads/test_future[12].cpp: Updated the tests to use
 	  the new call() semantics in order to shut down the Scheduler's
 	  event loop gracefully.

	* ace/Method_Object.cpp: Added a return value to the call()
 	  routine.  This can be used to indicate to the caller that it is
 	  necessary to shut down the event loop.

Mon Sep  9 02:07:08 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* ace/Service_Config.cpp (ACE_Service_Config): #ifdef's out the
 	  registration of signal handling to control reconfiguration on
 	  Win32 since it doesn't really handle signals very well.  Thanks
 	  to John Morey <jmorey@tbi.com> for bringing this to my
 	  attention.

	* ace/CORBA_Handler: Replaced CORBA_[123] with ACE_CORBA_[123].

	* examples/CORBA: Updated the test programs to work portably
 	  across different versions of Orbix.

	* ace/OS: Added a new wrapper for the getcwd() call.

	* examples/Threads/test_recursive_mutex.cpp: Added the use of
 	  ACE_Guard<> to illustrate how these work with the
 	  ACE_Recursive_Thread_Mutex.  Thanks to Gonzalo Diethelm
 	  <gonzo@ing.puc.cl> for motivating me to do this.

	* examples/Threads/test_process_{mutex,semaphore}: Added two new
 	  tests to illustrate how the ACE_Process_Mutex and
 	  ACE_Process_Semaphore work, respectively.

	* ace/Synch: Replaced the implementation of ACE_Process_Semaphore
 	  to use SV_Semaphore_Complex on UNIX platforms in order to get
 	  the same semantics for Win32 and for UNIX.  Thanks to the James
 	  Mansion <james@wgold.demon.co.uk> for recommending this.

	* ace/OS.h: Added some parens around the ACE BIT* macros so that
 	  the precedence levels would be dealt with correctly and we don't
 	  get any nasty surprises...

	* ace/{Synch_T,Synch}: Modified the implementation of all the
	  *acquire()/release() methods so they keep track of whether they
	  own the mutex.  Thus, if a code path needs to give up the mutex
	  within the lifetime of the mutex, and it calls mutex_.release(),
	  then the destructor will not call it again.  Thanks to the James
	  Mansion <james@wgold.demon.co.uk> for recommending this.

	* ace/{Synch_T,Synch}: Changed the name of the field result_ to
	  owner_ for the ACE_Thread_Muetx_Guard and ACE_Guard.  This is
	  more representative of the true purpose of this field.

	* ace/Synch: Updated ACE_Thread_Mutex_Guard so that it has the
	  same interface and semantics of ACE_Guard.  Thanks to the
	  ever-vigilant James Mansion <james@wgold.demon.co.uk> for
	  noticing this.

	* examples/Log_Msg/test_log_msg.cpp (main): Added a test of the
	  new ACE_Log_Msg::priority_mask() functionality.

	* ace/Log_Msg.cpp: Added a new method called priority_mask(),
	  which updates the new thread-specific priority_mask_ data member
	  with the new mask and returns the old mask.  This is useful for
	  applications written using ACE_Log_Msg.  Often, these have log()
	  calls with low priority such as LM_DEBUG that don't need to be
	  printed, but for which the logging code should not be removed.
	  The priority_mask() scheme makes it possible to selective enable
	  printing of certain priorities.  Thanks to Rochi Febo Dommarco
	  <rocky@alter.it> for suggesting this.

	* netsvcs/clients/Logger/indirect_logging.cpp (main): Modified the
	  test program so that it randomly selects logging priorities that
	  are powers of two.

	* ace/Log_Priority.h: Renumbered the LM_* logging flags so that
	  they are all powers of two.  This makes it easy to implement a
	  scheme for selectively printing only certain logging values.

Sun Sep  8 10:46:40 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Proactor.cpp: Fixed up the error handling in ACE_Proactor so
	  that it returns an error both in case of "bad errors," as well
	  as when ACE_WIN32 isn't defined.  Thanks to Amos Shapira
	  <amos_shapira@mail.icomverse.com> for reporting this.

Sun Sep  8 14:11:08 1996  Tim H. Harrison  <harrison@lambada.cs.wustl.edu>

	* examples/Reactor/Proactor/README: Updated the test_proactor.cpp
	  and README files to clarify the relationship between the
	  Proactor and ReactorEx.  This example uses the Proactor as the
	  main event loop (not the Reactor or ReactorEx).  Thus, this
	  application can only do overlapped I/O and timers
	  asynchronously.  To be able to react to other Win32 events, see
	  the ACE_ReactorEx and the examples/Reactor/ReactorEx/ test.
	  Thanks to Amos Shapira <amos_shapira@mail.icomverse.com> for
	  pointing out the ambiguity.

Sat Sep  7 14:09:21 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Task.cpp: Enhanced the activate() method so that the caller
	  can set the priority and the thread group id.  Thanks to
	  Karlheinz for this suggestion.

	* ace/OS.h: Added default values of 0 for the trailing arguments
	  for the {mutex,sema,cond}_init() methods.

	* examples/Threads/test_mutex.cpp: Added a new test program that
	  illustrates the difference between implementations of thread
	  mutex wrappers that use inheritance and dynamic binding vs. the
	  ACE approach (which doesn't use inheritance and dynamic
	  binding).  The results I got on my SPARCstation 20 model 712 is
	  included in the source file.  Thanks to James Mansion
	  <james@wgold.demon.co.uk> for motivating me to write this.

	* examples/Misc/test_singleton.cpp: Added a new test program that
	  illustrates the performance of using the Double-Checked Locking
	  pattern compared with the standard "Mutex::acquire()/release()"
	  approach.  Thanks to Jim Coplien <cope@research.bell-labs.com>
	  for encouraging me to get these performance numbers.

Tue Sep  3 00:38:47 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/XtReactor: Added minor fixes to XtReactor to fix complaints
	  about "bool" not being defined and the destructor
	  ~ACE_XtReactor() has already having a body.  Thanks to Andres
	  Kruse <Andres.Kruse@cern.ch> for these fixes.

	* ace/Mem_Map.cpp: Make sure that this->length_ is initialized to
	  0 in ACE_Mem_Map::map ().  Thanks to James Mansion
	  <james@wgold.demon.co.uk> for pointing this out.

	* ace/Thread.i (spawn_n): In ACE_Thread::spawn_n the sense of the
	  following check is wrong: 

	  for (i = 0; i < n; i++)
	  // Bail out if error occurs.
	    if (ACE_OS::thr_create (func, arg, flags, &t_id, 0, priority,
	                            stack == 0 ? 0 : stack[i],
				    stack_size == 0 ? 0 : stack_size[i]) != 0)
	      thread_ids[i] = t_id;
	    else
	      break;

	  The '!=' should be '=='.  Thanks to James Mansion
	  <james@wgold.demon.co.uk> for pointing this out.

	* include/makeinclude/rules.local.GNU (MAKEFILE): Changed the
	  $WRAPPER_ROOT/include/makeinclude/rules.local.GNU line that
	  says:

	  sed -e "s:$(WRAPPER_ROOT);$$(WRAPPER_ROOT);g" \

	  so that the double dollar is now "\$$" (prefixed the first
	  dollar sign with a backslash). If not, my shell will try to
	  execute WRAPPER_ROOT for some reason. With "\$$" it works as it
	  should.  Thanks to Marius Kjeldahl <marius@funcom.no> for
	  reporting this.

	* Released version 4.0.29 for testing.

	* ace/OS.i (thr_getspecific): Added a new case for OSF/1.  Thanks
	  to Martin Schoeckle <schoeckle@ike.uni-stuttgart.de> for
	  reporting this.

	* ace/Thread_Manager.cpp (spawn_i): Removed an invalid
	  initialization of ACE_hthread_t = 0, which doesn't work on all
	  pthreads platforms because pthreads uses a struct in some
	  implementations.  Thanks to Martin Schoeckle
	  <schoeckle@ike.uni-stuttgart.de> for reporting this.

	* man: Updated all the nroff and html documentation to conform to
	  the latest version of ACE.

	* netsvcs/lib/{Name_Handler,TS_Server_Handler}.cpp: Fixed
	  some mistakes in the ACE_TEMPLATES_REQUIRE_SPECIALIZATION
	  code so that all the services can be linked together without
	  multiply defined symbols.

	* netsvcs/lib/Name_Handler.cpp: Fixed a spot where we weren't
	  passing in an lvalue to send_request().  Why this wasn't showing
	  up earlier I don't know, but GCC caught it!

Mon Sep  2 00:47:00 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Thread_Manager.cpp: Updated all comparisons of ACE_thread_t
	  and ACE_hthread_t so that they use the ACE_OS::thr_equal() and
	  ACE_OS::thr_cmp() methods, respectively.  Thanks very much to
	  Martin Schoeckle <schoeckle@ike.uni-stuttgart.de> for identify
	  the need for this.

	* ace/OS: Added a new method called thr_cmp() which compares two
	  ACE_hthread_t values for equality.  Unfortunately, we can't just
	  compare these directly via == because on some platforms they are
	  implemented as structs.  Right now, I'm assuming that if
	  ACE_HAS_TID_T is enabled that we can compare tid_t's using ==.
	  If this turns out to be incorrect (e.g., if tid_t's are also
	  implemented as structs, please let me know).

	* ace/Future: Changed the overloaded result() method to a pair of
	  get()/set() methods.

	* tests/test_config.h: Fixed a bug in the reset() routine.  This
	  was originally deleting the global static ace_file_stream.
	  However, this was causing segmentation faults if destructors for
	  objects local to main() were trying to write to the output file.
	  Therefore, instead of deleting the ostream, we simply flush()
	  it!

	  In addition, also renamed the various functions in test_config.h
	  to make sure they don't conflict with any other names by
	  prefixing them with ace_test_...

	* ace: Added many small fixes for IRIX 6.2.  Thanks to Gonzalo
	  Diethelm <gonzo@ing.puc.cl> for reporting all of these!

	* ace/OS: Added a wrapper for the UNIX syscon() system call.

	* ace/LSOCK.cpp (recv_handle): Rearranged the casts so that things
	  work correctly on platforms with odd definitions ot struct
	  iovec.  Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for
	  reporting this.

	* ace/Task.cpp (ACE_Task_Exit): Rearranged the order in which we
	  shut down a Task via the Task_Exit hook so that we first
	  decrement the count of the threads in the task and *then* call
	  its close() hook.  This guards against cases where the close()
	  hook does something crazy like "delete this".

	* ace/XtReactor.h: Changed #include "X11/Intrinsic.h" to #include
	  <X11/Intrinsic.h>.  Thanks to Gonzalo Diethelm
	  <gonzo@ing.puc.cl> for suggesting this.

	* ace/Future.cpp (ACE_Future): Added some strategic "consts" to
	  the assignment operator and copy constructor for ACE_Future and
	  ACE_Future_Rep.

	* examples/Threads/test_task_three.cpp (main): Revised the test so
	  that it will shut itself down automatically when all the threads
	  have finished.

	* examples/Threads/test_task_two.cpp (main): Revised this test so
	  that it doesn't run forever, but only runs either 1000 times or
	  as many times as the user specifies on the command line.  Thanks
	  to Gonzalo Diethelm <gonzo@ing.puc.cl> for suggesting this.

	* ace/OS.i: Added an extra #else for thr_sigsetmask(),
	  thr_min_stack(), and thr_kill() for weirdo platforms that don't
	  conform to the other threading APIs...

Sun Sep  1 20:15:28 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* examples/ASX/Message_Queue: Changed the use of read(0, ...) and
	  write(1, ...) to ACE_OS::read(ACE_STDIN, ...)  and
	  ACE_OS::write(ACE_STDOUT, ...) in buffer_stream.cpp and
	  bounded_buffer.cpp.

	* ace/OS.i: Fixed the errno mapping of the cond_timedwait()
	  functions so that they set errno to ETIME rather than EBUSY when
	  timeouts occur.  This is necessary to support Solaris and POSIX
	  pthreads semantics on Win32.

	* build/SunOS5.5/examples/ASX/Message_Queue/buffer_stream.cpp:
	  Modified the example somewhat so that it uses the Singleton
	  thr_mgr() method from ACE_Service_Config.

Sun Sep  1 17:29:58 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* ace/ACE.cpp (map_errno): Added a new static method to the ACE
	  class.  This method allows us to map troublesome win32 errno
	  values (e.g. WSAEWOULDBLOCK) to values that standard C strerr
	  function understands.  Thank you Microsoft. 

	* ace/Log_Msg.cpp (log): Added a call to ACE::map_errno to the %p
	  option.  Now the ACE logger can begin to map Win32 error values
	  into meaningful strings.

	* netsvcs/lib/lib.mdp: Added a project file for the netsvcs
	  library.  This builds a dll into ace/netsvcs.dll (not into the
	  netsvcs/lib directory).  This reduces the number of paths needed
	  in %PATH%.

	* examples/Tokens: Renamed this directory netsvsc/clients/Tokens.

	* ace/ace.mdp: Removed wsock32.lib from the ace files listing.
	  The problem is that we can't assume where MSDEV is installed.  I
	  added wsock32.lib and advapi32.lib to the
	  build/settings/link/library_modules line.

	* ace/config-win32-msvc4.0.h: Disabled the "C4355: 'this' : used
	  in base member initializer list" warning.  Thanks to Amos
	  Shapira for figuring this out for us.  Although "this" is
	  unneeded for win32, it is required for compilers on other
	  platforms (e.g., AIX).

	* ace/Message_Queue.cpp (dequeue_head_i): Andres Kruse pointed out
	  that we weren't doing head_->prev (0), when dequeuing!

Tue Aug 27 21:00:25 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* include/makeinclude/platform_sunos5_sunc++_4.1.GNU (CXX): Added
	  Andres Kruse's changes for SunC+ 4.1.

	* ace: Fixed line # 12 of ace/config-sunos4-sun4.1.4.h, 
	  which read:

	  "#define ACE_HAS_SVSV_IPC"  (ACE_HAS_ ess vee ess vee _IPC)

	  to

	  "#define ACE_HAS_SYSV_IPC"  (ACE_HAS_ ess wye ess vee _IPC)

	  Fix another problem:

	  #define ACE_LACKS_THREAD_STACK_ADDR     (OS.cpp)

	  was inconsistently defined in:

	  #define ACE_LACKS_THREAD_STACK_ADDRESS  (config-aix-4.1.x.h)

	  Thanks to Alan Stweart <Axs2@osi.com> for reporting
	  this!

Mon Aug 26 00:34:05 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Updated all of ACE such that the ACE_GUARD* macros now all take
	  the name of the ACE_*Guard* that they will use as the scoped
	  locking object.  This is important for several reasons:
	  
	  1. It make it more clear what is going on in the code, rather
	     than hiding behind the macros!

	  2. It is now possible to have multiple ACE_GUARD* macros in the
	     same scope by calling each scoped locking object a different
	     name.  This is used in the Local_Tokens.cpp file.

	* ace/Synch.h (ACE_Null_Mutex_Guard): Added the locked() method so
	  that this signature will conform to the one expected of
	  ACE_Guard.

	* tests: Added a new file Test_Future.cpp, which tests the new ACE
	  Futures mechanism using Active Obejcts.  Thanks to Andres Kruse
	  <kruse@cern.ch> for contributing this test.

	* ace: Added three new files: Future.{h,cpp},
	  Method_Object.{h,cpp}, and Activation_Queue.{h,cpp}, which
	  implement Polymorphic Futures.  Thanks to Andres Kruse
	  <kruse@cern.ch> for contributing these.

	* ace/Stream.cpp (dump): Replaced LM_INFO with LM_DEBUG.

Sun Aug 25 21:57:57 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * ace: Rather than using operator new directly, most of ACE now
	  uses the ACE_NEW and ACE_NEW_RETURN macros.  For instance,
	  rather than writing:

	  if (token_manager_ == 0)
	    token_manager_ = new ACE_Token_Manager;

	  we should write:

	  if (token_manager_ == 0)
	    ACE_NEW_RETURN (token_manager_, ACE_Token_Manager, 0);

          The reason for this is that it makes it much easier to ensure
	  that all dynamic memory allocation errors are treated uniformly.
	  I've updated the entire ACE library code tonight to make this
	  usage consistent whenever possible.

Sat Aug 24 11:51:38 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Time_Value.h: Simplified various things so that the nasty
	  macros necessary to build DLLs on Win32 will be simplier.  In
	  addition, I will only #include <sys/time.h> for those platforms
	  that don't already do this in <time.h> (i.e., if
	  ACE_NEEDS_SYSTIME_H is defined in config.h).  Please let me know
	  if you run across any platforms like this.

	* ace/TLI_{Connector,Acceptor}: Added two additional parameters at
	  the end of the connect() and accept() methods, respectively, so
	  that the ACE TLI wrappers can be used with X.25.  Thanks to Ajit
	  Sagar <asagar@spdmail.spd.dsccc.com> for suggesting this fix.

	* ace: Integrated Eric Newton's XtReactor into the Makefile.  If
	  you want to include this into ACE, make sure to define
	  ACE_HAS_XT in the config.h file.

	* examples/Misc: Integrated the XtReactor tests.

	* ace/OS.i (getservbyname,gethostby*): Fixed a suble omission --
	  any calls to socket function should be wrapped by the
	  ACE_SOCKCALL_RETURN macro in order to make the errnos work
	  correctly on Win32.

	* ace/OS: Added support for the getprotoby{name,number} wrappers.
	  Thanks to Joe DeAngelis <bytor@faxint.com> for suggesting this.

	* ace/Connector.cpp: Fixed a subtle bug in the ACE_Connector.
	  The problem centered around the following line in
	  cleanup_AST():

	  if (this->handler_map_.find (handle, ast) == -1)

	  This lookup always failed because the key, the handle of the
	  service handler, was always -1.  The service handler's handle is
	  not set until a successful connection is made and connector
	  transfers ownership of the handle to the service handler.  The
	  fix for this is to store the ACE_HANDLE in the ACE_Svc_Tuple
	  *separately* from the ACE_Svc_Handler.  Thanks to Bill Gerecke
	  <gerecke@rayva.org> for being so persistent in tracking this
	  down.

	* ace/ARGV.cpp (ACE_ARGV): Added a nifty new constructor that
	  converts argv-style vectors of strings into a single string
	  (this is the reverse of what the original constructor does!).

	* ace/ACE: Added a new utility method called strecpy(), which
	  copies <t> to <s>, returning a pointer to the end of the copied
	  region (rather than the beginning, a la <strcpy>.

Thu Aug 22 15:43:58 1996    <harrison@samba.cs.wustl.edu>

	* ace/OS.h: Changed the interface of ACE_OS::fork_exec (char
 	  *const argv[]).  (There is no longer a separate const char *path
 	  parameter.  Now, argv[0] must be the full path name to the
 	  executable.

	* tests/Time_Service_Test.cpp:  Updated the Time Service
	  one-button test to use the new ACE_OS::fork_exec.  I didn't
	  event break it.

	* tests/Tokens_Test.cpp:  Updated the Tokens one-button test to
	  use the new ACE_OS::fork_exec.  It actually works now.

	* tests/test_config.h: Added some more #defines to help simplify
	  path differences between NT and UNIX.  Perhaps these should be
	  moved into OS.h?

Thu Aug 22 13:46:58 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Thread_Manager.cpp (ACE_Thread_Control): The status_ member
	  in ACE_Thread_Control() was not being initialized!  This caused
	  Purify to complain loudly about invalid memory accesses. I have
	  added an initialiser to ACE_Thread_Control::ACE_Thread_Control
	  to set status_ to 0.  Thanks to Ross Dargahi <rossd@krinfo.com>
	  for reporting this.

	* ChangeLog: The ACE configuration files "config-irix*.h" defined
 	  'ACE_HAS_SIGINFO' to indicate that IRIX supports SVR4 extended
 	  signals.  This should be 'ACE_HAS_SIGINFO_T' instead.  Thanks to
 	  Craig Johnston <johnston@tortilla.ds.boeing.com> for reporting
 	  this.

Wed Aug 21 21:09:01 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Time_Value.h: Added an extra condition, #if defined
	  (ACE_BUILD_DLL) so that ACE_Svc_Export evaluates to
	  something. Previously, it was evaluating to nothing in some
	  files such as Naming_Context.cpp where we were doing #define
	  ACE_BUILD_DLL and not #define ACE_BUILD_SVC_DLL.

Wed Aug 21 00:33:17 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/ACE.cpp (format_hexdump): Fixed a minor bug in
	  format_hexdump().  If the buffer to dump is a multiple of 16 it
	  prints an extra blank line.  ALso fixed the code to use spaces
	  rather than tabs and put an extra space between the first 8 HEX
	  bytes and the second.  Thanks to Luca Priorelli
	  <lucapri@mbox.vol.it> for this code.

	* ace/Log_Msg.h (ACE_HEX_DUMP): Added a new logging macro:
	
	  #define ACE_HEX_DUMP(X) \
	    do { int __ace_error = errno; \
	      ACE_Log_Msg *ace___ = ACE_Log_Msg::instance (); \
	      ace___->set (__FILE__, __LINE__, 0, errno, ace___->restart (),
	      ace___->msg_ostream ()); \ ace___->log_hexdump X; \
	    } while (0)

	  which makes it possible to dump info in HEX.  Thanks to Luca
	  Priorelli <lucapri@mbox.vol.it> for suggesting this.

        * ace/config-win32-msvc4.0.h: Added 
	
	  #define _WINSOCKAPI_

	  To avoid multiple inclusions.  Thanks to Luca Priorelli
	  <lucapri@mbox.vol.it> for suggesting this.

        * ace/OS.h: enclosed the #define of WIN32_LEAN_AND_MEAN macro
	  definition between #ifndef ... #endif to avoid compiler
	  warnings.  Thanks to Luca Priorelli <lucapri@mbox.vol.it> for
	  suggesting this.

	* ace/SOCK.cpp (win32_fini): Fixed a potential problem in ACE
	  where any code of the form:

	  ACE_DEBUG ((LM_DEBUG, "%d", GetLastError()));

	  will reset errno a couple of times before GetLastError() gets
	  called. So the result is always 0.  The fix is to say:

	  int ret = GetLastError();
	  ACE_DEBUG ((LM_DEBUG, "%d", ret));

	  Thanks to Luca Priorelli <lucapri@mbox.vol.it> for noticing
          this.

	* ace/Connector.cpp (create_AST): Was missing a return 0; if we
	  successfully register a cancellation id.  Thanks to William
	  L. Gerecke <gerecke@rayva.org> for reporting this bug.

	* ace/Module.h: Added a non-existent friend class to get ACE 
	  to stop complaining
	  
	  private:
	    friend class ACE_Shutup_GPlusPlus;  // Turn off g++ warning
	    ~ACE_Module (void);		
	    // *Must* use dynamic allocation.

	  Thanks to Eric Newton for the suggestion.

	* ace/Svc_Conf.y (ace_create_service_type): Removed some stray
	  calls to ACE_ERROR that were left over from earlier
	  configurations of ACE.  Thanks to Gonzalo Diethelm
	  <gonzo@ing.puc.cl> for reporting this.

	* ace/Log_Msg.cpp (instance): Fixed the #ifdefs so that
	  ACE_MT_SAFE implies ACE_HAS_THREAD_SPECIFIC_STORAGE.  Thanks to
	  Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting the need for
	  this.

Tue Aug 20 13:09:55 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

        * INET_Addr.cpp, line 84: Irix's C++ is not able to determine
	  whether to use the set(u_short,ACE_UINT32,int) or the
	  set(u_short,const char [],int), since on Irix, INADDR_ANY is 0.
	  I cast the value so that the call would read set(port,
	  ACE_UINT32(INADDR_ANY)) and everything went fine.  Thanks to
	  Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this.

	* ace/Synch[_T]: Added a new wait() method that takes a first
	  parameter which is the mutex used to serialize access to the
	  condition.  This is useful if you want to store the
	  ACE_Condition object in shared memory (in which case, the use of
	  a reference to mutex_t doesn't work!).  Thanks to Mark Patton
	  <mark_patton@ftw.paging.mot.com> for recommending this approach.

	* ace/Task.h: Added a forward template declaration for
	  ACE_Task_Exit so that it will compile on HP/UX.  Thanks to Tim
	  Ottinger <tottinge@csci.csc.com> for pointing this out.

	* ace: changed line 19 of ace/Str_Buf.h from

	  #include "OS.h"

	  to:

	  #include "ace/OS.h"

	  Fixed similar problems with OS.h at line 1154 and Dump.h at line
          150.  Thanks to Alan Stewart <axs2@osi.com> for reporting this.

Tue Aug 20 20:18:49 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* tests/TSS_Test.cpp (main): Fixed a small typo. I was referencing
	  the wrong variable but didn't catch it since it was in the #if
	  !defined (ACE_HAS_THREADS) section. Fixed the typo and also 
	  renamed the variable called big_count to iterations.  Thanks to
	  Tim Ottinger <tottinge@csci.csc.com> for pointing this out.

Mon Aug 19 19:25:50 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* {examples,apps,tests}: Removed the use of zerop from these
	  files, as well...

	* ace/{Acceptor.cpp,Name_Proxy.cpp,Token.i}: Removed the use of
	  zerop from these files, as well...

	* ace/Connector.cpp (connect_svc_handler): It looks like our good
	  friend ACE_Time_Value::zerop isn't getting initialized correctly
	  on Win32.  Therefore, I've replaced it with a direct use of
	  &ACE_Time_Value::zero.

	* ace/Time_Value.cpp: Removed the static pointer variable "zerop"
	  since there was no guarantee it was getting intialized before it
	  is used!  Instead of using ACE_Time_Value::zerop, use
	  &ACE_Time_Value::zero.  Thanks to William L. Gerecke
	  <gerecke@rayva.org> for reporting this problem.

	* ace/OS: Added zillions of changes to make ACE compile with OSF/1
	  and its DCE threads implementation.  Thanks to Martin Schoeckle
	  <schoeckle@ike.uni-stuttgart.de> for sending these.

	* ace/config-osf1-3.2.h: Updated this file with fixes for OSF/1 by
	  Martin Schoeckle <schoeckle@ike.uni-stuttgart.de>.

	* ace/ACE.cpp (handle_timed_complete): Added new logic to
	  ACE::handle_timed_complete() so that it sets errno to
	  ECONNREFUSED if the connection is refused by the server.  When
	  you issue an asynchronous connect request, to complete it, you
	  will use complete() with a timeout.  However, complete can fail,
	  and then it will deallocate any resource, (i.e. close down the
	  socket handle), also for timeout expiration.  So, a user
	  interested in retrying to complete a connection while the
	  timeout expires will not use complete(); but rather will use
	  handle_timed_complete().  In fact, using handle_timed_complete()
	  the user could detect the reason of a failure (by examining
	  errno) and decide how to proceed.  In the old ACE version the
	  problem was that, if handle_timed_complete() failed because of
	  the recv() returning 0, errno remained unchanged and so its
	  value could be quite misleading with respect to the reasons of
	  the failure.  Thanks to Antonio Tortorici
	  <antonio@rh0011.roma.tlsoft.it> for this fix and the explanation
	  above.

	* ace/OS.h: Added support for Borland 5.0's uint64.  Thanks to
	  Hani Yakan <hani@i-online.com> for suggesting the strategy to
	  accomplish this.

Mon Aug 19 15:52:07 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

        * tests: Added new macros to the test_config.h file in order to
	  simplify the testing.

Mon Aug 19 00:21:22 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

 	* Re-released version 4.0.28 for testing (will change the version
	  number after Tim gives me the new Token stuff).

	* {netsvcs/lib,tests/test_config.h}: Removed spurious dependencies
	  on fstream.h and iostream.h.  Thanks to Alan Stewart
	  <axs2@osi.com> for reporting this.

Sat Aug 17 17:25:49 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Reactor: Removed the use of "inline" in the Reactor.cpp
	  files because this was causing problems with some
	  compilers/linkers.  Thanks to Gonzalo Diethelm
	  <gonzo@ing.puc.cl> for recommending this.

	* examples/Misc/test_XtReactor1.cpp: Added a new test of the
	  XtReactor, courtesy of Eric Newton <ecn@clark.net>.

	* ace/config-hpux-10.x.h: According to Eugene K. Plaude
 	  <jec@r-style.msk.su>, HP-UX 10.01 supports user-level threads
 	  based on the pthreads interface specified by POSIX in 1003.4a,
 	  Draft 4 (which is basically DCE threads).  Therefore, I've
 	  enabled the ACE_HAS_DCETHREADS symbol in the config-hpux-10.x.h
 	  configuration file.  If this isn't correct, please let me know.

Sat Aug 17 02:18:39 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* examples/Tokens/manual/README: Added a new Token example
	  application.  The manual test gives users a text-based
	  interactive interface to local or remote tokens.  This is
	  extremely useful for manually testing the token server and
	  setting up deadlock scenarios.  See the README file for more
	  details.

	* examples/Tokens/deadlock/README: Updated the deadlock example
	  application to test the new deadlock detection algorithm for
	  readers/writer locks.  I also added the use of Token Invariants
	  to ensure correctness of the mutexes and readers/writer locks.
	  See the README file for more details.

Fri Aug 16 22:16:05 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* ace/Token_Manager.cpp: Updated all Token code to use
	  ACE_OS::last_error instead of errno.

Fri Aug 16 00:03:24 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

 	* After a long hiatus, released version 4.0.28 for testing.

Thu Aug 15 21:04:35 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* man: Updated all the ACE manual pages and html pages to reflect
 	  recent changes.

	* netsvcs/lib/Server_Logging_Handler.cpp: Fixed an omitted
 	  "ACE_BUILD_SVC_DLL" that was causing linker errors on NT.
  	  Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting
 	  this.

	* examples/Log_Msg/test_log_msg.cpp: Added a test for the new
	  log_hexdump() function.

	* ace/Log_Msg.cpp (log_hexdump): Integrated the log_hexdump() code
 	  into the ACE Log_Msg abstraction.  Thanks to Luca Priorelli
 	  <lucapri@mbox.vol.it> for fixing this and for Todd Montgomery
 	  for originally supplying the code.

	* ace/Signal.cpp (ACE_Sig_Handlers): Moved the #endif /* HPUX */
	  down to the end of the file so that it works correctly on HPUX.
	  Thanks to Eric C. Newton <ecn@clark.net> for report this bug.
	  

	* ace/OS.i: Updated the behavior of thr_join() so that it will do
 	  a ::CloseHandle after getting the exit status.  Thanks to the
 	  ever vigilant James Mansion
	  (mansionj@lonnds.ml.com) for noticing this.

	* examples: Finally added Tim and Prashant's examles/OS directory,
 	  which contains a test that illustrates a "portable" means to
 	  spawn processes on NT and UNIX.

	* ace/Malloc_T.cpp (next): Added an overloaded next() method that
 	  returns the name that is bound to the pointer in the
 	  Malloc_Iterator.  This is useful in order to differentiate
 	  entries in the pool based on their name.  Thanks to Kim Gillies
 	  <gillies@noao.edu> for suggesting this.

	* ace: Changed all uses of thread_t, thread_key_t, mutex_t,
 	  rwlock_t, sema_t, cond_t, etc. to ACE_* in order to avoid
 	  polluting the name space.  Also switched from using macros to
 	  using typedefs whereever possible.  Thanks to Gonzalo Diethelm
 	  <gonzo@ing.puc.cl> for recommending this.

	* ace/System_Time.cpp: Added template specializations for
 	  templates used in the ACE_System_Time class.  This should solve
 	  some nasty undefined templates problems with GCC...  Thanks to
 	  Joseph DeAngelis <bytor@faxint.com> for pointing out the
 	  problem.

	* ace/Name_Space.cpp: Fixed the file Name_Space.cpp as follows:

  	  // Name_Space.cpp
	  #define ACE_BUILD_DLL
	  //#include "Name_Space.h"
	  #include "ace/Name_Space.h"     

	  Thanks to Eugene K. Plaude <jec@r-style.msk.su> for fixing this!

	* ace/config-hpux-10.x.h: Added support for TLI since according to
 	  Eugene K. Plaude <jec@r-style.msk.su> this should work.  If not,
 	  please let me know.

Wed Aug 14 21:29:46 1996  Douglas C. Schmidt  <schmidt@tango.cs.wustl.edu>

	* examples/Reactor/Logger: rearranged the Logger directory so it
 	  would be more clear what the client and server programs did and
 	  how to run them.

	* examples: Merged the contents of the SVR4 examples directory
 	  into the IPC_SAP/SOCK_SAP directory so that we can remove the
 	  SVR4 directory altogether (it wasn't contributing much...).

	* examples: Removed the vestigal Win32 tests since ACE now runs on
 	  Win32 and we don't need a separate test directory.

	* netsvcs/client: Renamed the file remaining file in this
 	  directory to logging_app.cpp since I moved the other file to the
 	  examples/Reactor/Logger directory.

	* ace/Reactor.cpp (check_handles): If eh->get_handle() returns -1
 	  the select() code will index the [-1] element of an array.  To
 	  fix this, I've added a check of the value returned from
 	  eh->get_handle().  Thanks to Eric C. Newton <ecn@clark.net> for
 	  reporting this.

	* ace/OS.i (sema_wait): Fixed a subtle bug in the Pthreads
	  wrappers that surfaced on the SGI IRIX 6.2 port.  There was some
	  code that looked like this:

	  pthread_cleanup_push();
	  int result = 0;
	  ...
	  pthread_cleanup_pop();
	  return result;
 
          However, on Irix 6.2, the push introduces a new scope that is
	  closed by the pop, so result goes out of scope before returning.
	  Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for pointing this
	  out.

	* ace/OS.h: Changed the definition of pthread_mutex_t and
	  pthread_cond_t to mutex_t and cond_t to be consistent with other
	  usage in ACE.  Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for
	  pointing this out.

Wed Aug 14 01:25:47 1996    <harrison@samba.cs.wustl.edu>

	* ace/SPIPE_Acceptor.cpp: Added the PIPE_TYPE_MESSAGE |
 	  PIPE_READMODE_MESSAGE flags to CreateNamedPipe pipe options so
 	  that data is received in messages rather than as a stream.  This
 	  is consistent with the behavior of the SPIPE_Connector.  When we
 	  have time, we need to extend the interface so that stream pipes
 	  are also supported, as well.

	* SPIPE_Acceptor.cpp: Made the ACE SPIPE in and out buffer sizes
 	  10 k.  The previous size was just 512 bytes.  This larger buffer
 	  size helps decrease flow control.

Tue Aug 13 23:21:46 1996    <harrison@samba.cs.wustl.edu>

	* examples/Connection/blocking: Updated the blocking SPIPE example
 	  application to use a pool of threads in the proactor to handle
 	  incoming client messages.  The SPIPE-acceptor example
 	  illustrates how named pipes are used on NT. Once the server
 	  establishes a connection to a single client, it spawns a thread
 	  pool to handle incoming requests via the proactor event
 	  loop. That is, a separate thread from the pool is used to
 	  process each message sent by a client.  The size of the thread
 	  pool can be specified by command-line arguments.  This example
 	  leverages the queueing performed by the NT kernel to trivially
 	  implement a thread pool architecture.  See
 	  examples/Connection/blocking/README for more details.

	* Service_Config.h: Added a <thread> parameter (with a default
 	  size of 0) to the proactor accessor method.  This allows
 	  applications to specify the size of the thread pool that can
 	  block on Proactor::handle_events.

Tue Aug 13 02:30:58 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Task: Added a new public interface called thr_count().  This
	  returns a count of the number of threads running within a Task.
	  If the value returned is 0, then the Task is a Passive Object.
	  If the value returns is > 0 the task is an Active Object, and
	  the value is a count of the number of threads running within the
	  object at this snapshot of time.

	* ace/OS: I implemented Karlheinz's suggested optimizations for
	  the ACE condition variable implementation under Win32.  Here's
	  the deal...  The original implementation used an internal_mutex
	  to ensure that access to the count of the number of waiters was
	  serialized between the waiter and signaler threads.  The new
	  implementation is designed so that only the waiter threads
	  access the waiter count.  Therefore, we can utilize the
	  external_mutex to serialize access to this, thus eliminating the
	  need for the internal_mutex.  However, this means that code
	  *must* be written using the standard condition variable idiom,
	  i.e.,

	  int resources ()
	  {
	    external_mutex.acquire ();
	    
	    // ...

	    cond.signal ();
	    external_mutex.release ();
	  }

	  Rather than like this:

	  int resources ()
	  {
	    external_mutex.acquire ();
	    
	    // ...
	    
	    external_mutex.release ();
	    cond.signal ();
	  }

	  which is what some thread programming books recommend as an
	  optimization.  However, you should be careful not to use this
	  form since it can lead to "lost wakeup" bugs caused by the fact
	  that the implementation of ACE_OS::cond_signal will test if the
	  waiter count > 0 *without holding any locks*!!!

	  Fortunately, ensuring this shouldn't be a problem since most ACE
	  code uses the following idiom:
	  
	  int resources ()
	  {
	    ACE_Guard mon (external_mutex);
	    
	    // ...

	    cond.signal ();
	    // Destructor of mon releases external_mutex.
	  }
	  
	  Clearly, there are subtle tradeoffs between performance and
	  programmability here...

	* ace/Synch: Updated all of the ACE semaphore wrappers to take the
	  new "max" value as their final constructor argument.

	* ace/OS: Added a new default argument to the end of the
	  sema_init() method.  This allows us to specify the maximum value
	  of the semaphore (this is only important on NT).  Currently, it
	  is hard-coded to 0x7fffffff in uses.  The new approach makes it
	  possible to set the max to a different value.  Thanks to
	  Karlheinz for requesting this.

	* ace/Message_Queue.cpp: Added an implementation of the dump().
	  Thanks Karlheinz.

	* ace/Synch.cpp: Added an implementation of the dump() method.
	  Thanks Karlheinz.

	* ace: Updated all usage of ACE_Thread_Mutex_Guard so that it now
	  uses the ACE_GUARD* macros correctly.  Thanks to Chris Eich
	  <Chris_Eich@optilink.optilink.dsccc.com> for pointing out the
	  need for this.

	* examples/Threads: Added Karlheinz's new test_barrier2.cpp test
	  program that makes sure that the ACE_Message_Queues are working
	  correctly when accessed by multiple threads.

	* netsvcs/lib/Server_Logging_Handler.cpp (handle_logging_record):
	  Fixed an errant use of ACE_Guard, which wasn't properly checking
	  of the Guard acquired the lock.  Thanks to Chris Eich
	  <Chris_Eich@optilink.optilink.dsccc.com> for pointing this out.

	* ace/OS.h (ACE_GUARD): Added default "ace_mon" implementations of
	  type ACE_Null_Mutex even in cases where there's no threading
	  defined so that code accessing ace_mon.release() and
	  ace_mon.acquire() will compile correctly.

	* apps/Gateway/Gateway/Channel.h:  Fixed the code so
	  that we don't try to use TLI if the platform doesn't support it
	  (instead, we'll use sockets).  Thanks to Marius Kjeldahl
	  <marius@funcom.no> for reporting this problem.

	* examples/ASX/Event_Server/{Supplier,Consumer}: Fixed the code so
	  that we don't try to use TLI if the platform doesn't support it
	  (instead, we'll use sockets).  Thanks to Marius Kjeldahl
	  <marius@funcom.no> for reporting this problem.

Mon Aug 12 14:50:47 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* examples/Misc: Added Eric Newton's <ecn@clark.net> test case for
	  his XtReactor integration.

	* ace: Included Eric Newton's <ecn@clark.net> code that integrates
	  ACE with the Xt event loop.  This still needs a bit of work
	  (e.g., making it thread-safe and incorporating signal support), so
	  I haven't added it to the Makefile yet.  If someone can take the
	  time to fix it up, I'll be happy to integrate it into ACE.

	* ace/Message_Queue.cpp (dequeue_head): Fixed the mother of all
	  bugs in the ACE_Message_Queue implementation...  The problem was
	  that I was trying to be too clever by optimizing the number of
	  Condition::signal() calls by only calling signal() when the
	  queue changed state from empty to non-empty (or full to
	  non-full).  It turns out that this optimization works fine for a
	  single producer/consumer case, but fails when there are multiple
	  consumers.  The fix was just to call signal() every time.  This
	  should be ok because the underlying Condition variable
	  implementation will perform the optimization in the correct
	  fashion.  Thanks to the omniscient Karlheinz for detecting this
	  problem and reporting it.

Sun Aug 11 15:52:07 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* tests: Made minor changes to test_config.h, SPIPE_Test.cpp, and
	  UPIPE_SAP_Test.cpp to accomodate the change made to SPIPE_Addr.
	  SPIPE_Addr now accepts a string of the form [host:]port and then
	  creates the rendezvous point. Originally, SPIPE_Addr would
	  assume that the string being passed in was the actual rendezvous
	  point. 

Sat Aug 10 18:41:21 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* netsvcs/lib/Logger.cpp (init): Added a new service to netsvcs
	  called ACE_Logger which allows us to control the output of all
	  the services. The ACE_Logger service can be invoked with
	  different flags (such as STDERR|OSTREAM) which in turn sets
	  ACE_Log_Msg to direct the output of all the services to the
	  appropriate stream(s). Note that if a service needs to stay
	  unaffected from ACE_Logger, it should be invoked before
	  ACE_Logger gets invoked. Also note that like other services in
	  netsvcs, ACE_Logger can also be dynamically linked in.

Sat Aug 10 14:23:07 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Added Steve Huston's <shuston@ultranet.com> patches to get ACE
	  to compile on UnixWare 2.01.  This mostly involved changes to
	  the internal types used by the socket wrappers.  Thanks Steve!

Fri Aug  9 01:34:19 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* examples/ASX/UPIPE_Event_Server/Options.cpp (print_results):
	  Added a typedef to avoid problems if a platform doesn't support
	  prusage_t.  Thanks to Marius Kjeldahl <marius@funcom.com> for
	  reporting this.

	* include/makeinclude/platform_linux_pthread.GNU.  The line that
	  say:

	  LIBS    = -lpthreads -lstdc++

	  was modified to say:

	  LIBS    += -lpthreads -lstdc++

	  Thanks to Marius Kjeldahl <marius@funcom.com> for reporting
          this.

Fri Aug  9 18:26:16 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Local_Name_Space.cpp (reset): Fixed a subtle (yet very
	  annoying bug). In switching contexts a test program would hang
	  after a certain number of switches. Having gone through the code
	  thoroughly and with the aid of Purify, the bug was narrowed down
	  to an extraneous delete taking place in
	  ACE_Name_Space::reset(). Essentially, we do not need to delete
	  ACE_Name_Space_Map::instance() which is actually the
	  SHARED_MALLOC since it gets deleted in the destructor of
	  ACE_Local_Name_Space.

Thu Aug  8 17:55:20 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/SPIPE_Addr.cpp (set): Implemented
	  ACE_SPIPE_Addr::string_to_addr(). Modified ACE_SPIPE_Addr::set()
	  using code provided by Brad Flood to create the rendezvous
	  point. Note that originally ACE_SPIPE_Addr constructor and set()
	  would take the actual rendezvous point but now they rely on
	  being passed a string which is of the format "[host]:port"
	  (where host is optional). The rendezvous point is then created
	  by extracting from the string the hostname (if any) and also
	  using the port number as the unique pipe name. Note that this
	  approach works on both UNIX and Win32.

Mon Aug  5 20:15:59 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/OS.i (last_error): Fixed a typo. In the set and get methods
	  last_error(), there should be a check for "if defined
	  (ACE_WIN32)" and not "if defined (ACE_HAS_WIN32)"

Wed Aug  7 00:21:42 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Log_Msg.h: Replaced all uses of errno *following calls to
	  ACE_Log_Msg::instance()* so that we first cache errno in a local
	  variable called __ace_errno.  We need to do this because
	  ACE_Log_Msg::instance() can reset errno == 0.  Thanks to 
	  Tim for pointing this out.

Mon Aug  5 20:15:59 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/OS.i (last_error): Fixed a typo. In the set and get methods
	  last_error(), there should be a check for 
	  "if defined (ACE_WIN32)" and not "if defined (ACE_HAS_WIN32)"

Sat Aug  3 14:52:32 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* examples/Win32/win32_client.cpp: Changed ACE_GUARD_RETURN to
	  ACE_GUARD in the method Errno::flags since the return type is
	  void. 

	* examples/Connection/non_blocking/CPP-connector.cpp: Made some
	  minor changes to get things compiling on Win32. The call to
	  handle_close now takes zero as the first argument (which is
	  never used). Also the arguments to ACE_SERVER_ADDRESS are now
	  swapped (hostname followed by port number) to be consistent with
	  the change made to the macro. Thanks to Brad Flood for
	  suggesting these changes. 

	* examples/Connection/non_blocking/CPP-acceptor.cpp: Made minor
	  changes to some of the methods to make sure all control paths
	  return a value. Also changed the default port number to
	  ACE_DEFAULT_SERVER_PORT_STR to match what the connector tries to
	  connect to. Thanks to Brad Flood <BFLOOD@slc.unisysgsg.com> for
	  suggesting these changes.

	* ace/OS.h (ACE_SERVER_ADDRESS): Modified the macro
	  ACE_SERVER_ADDRESS so that it creates a string of a server
	  address with a "host:port" format. Previously the order was
	  reversed. Thanks to Brad Flood for suggesting this change.

Sat Aug  3 00:07:26 1996  Douglas C. Schmidt  (schmidt@lambada.cs.wustl.edu)

	* ace: Fixed problems with recursive tracing of ACE_TRACE by
	  commenting out certain constructors in IPC_SAP.cpp,
	  FIFO_Send_Msg.cpp, FIFO_Send.cpp, and FIFO.cpp.  Thanks to
	  Karlheinz for finding and reporting these fixes.

Fri Aug  2 22:19:05 1996  Douglas C. Schmidt  (schmidt@lambada.cs.wustl.edu)

	* ace/ACE.cpp (format_hexdump): Fixed an infamous "off by one" bug
	  that was causing this to fail on Win32 (time to switch to Java? ;-)).
	  Thanks to lucapri@mbox.vol.it for finding this.

Thu Aug  1 14:08:30 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/CORBA_Handler.cpp (activate_service): Fixed a typo caused by
	  an omitted ENDTRY.  Thanks to Garrett Conaty
	  <gconaty@outbackinc.com> for noticing this.

Mon Jul 29 10:03:16 1996  Douglas C. Schmidt  (schmidt@lambada.cs.wustl.edu)

	* examples/Win32/win32_client.cpp: There was a typo in one of the
	  ACE_GUARD macros.  Thanks to Tim Ottinger
	  <tottinge@csci.csc.com> for pointing this out.

Mon Jul 22 12:41:22 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Local_Name_Space.cpp (reset): Added a new method
	  ACE_Name_Space_Map::reset() which deletes the instance of
	  ACE_Name_Space_Map. This forces instance() to create a new
	  instance using a new context file in the case of the context
	  having changed. I make use of this in
	  ACE_Local_Name_Space::create_manager().

Fri Jul 19 12:28:07 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/System_Time.cpp (get_master_system_time): Modified
	  ACE_System_Time::get_master_system_time() so that if an entry
	  for the time is not found in shared memory (indicating that no
	  Clerk is running), then we should just return the local time of
	  the host.

	* netsvcs/lib/TS_Clerk_Handler.cpp (update_time): Modified
	  ACE_TS_Clerk_Handler::update_time() so that if the Clerk is not
	  connected to any servers, is sets the delta time to zero
	  allowing clients to then use the local time of the host.

Wed Jul 17 22:19:53 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/UPIPE_Connector.cpp (connect): Added an #ifdef around the
	  check of ACE_OS::isastream (handle) in
	  ACE_UPIPE_Connector::connect() since the call is not supported
	  on NT.

Thu Jul 11 22:22:57 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* ace/OS.i (kill): Modified ACE_OS::kill so that it works on NT.
  	  It takes a process ID, creates a handle for the associated
 	  process, and calls TerminateProcess on the handle.  This is
 	  actually pretty dangerous according to the NT documentation.
  	  Can majorly confuse DLLs.  Does the same old thing on UNIX.

	* ace/OS.cpp (fork_exec): Added a fork_exec operation to ACE_OS.
  	  This works on UNIX and NT.  It combines the forking and exec'ing
 	  into one call.  This has to be combined since Win32
 	  CreateProcess only starts applications from scratch (unlike UNIX
 	  fork).

	* examples/OS/test_os.cpp: Added a new example application to test 
	  the new ACE_OS::fork_exec and ACE_OS::kill operations.

Tue Jul  9 13:04:14 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Service_Manager.cpp (reconfigure_services): To improve
	  portability on Win32 and UNIX I replaced the use of a signal to
	  trigger reconfiguration to instead make a call to the new
	  ACE_service_Config::reconfig_occurred() method.  This should
	  actually perform the same as the original approach, since all
	  the signal handler ever did was to set this flag!  Thanks to
	  Karlheinz for pointing out the need for this.

	* ace/Service_Config.h: Added a new static public method called
	  reconfig_occurred(sig_atomic_t) to set if a reconfiguration
	  should take place the next time through the event loop.

Mon Jul  8 14:20:01 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Time_Value.h: Added "ACE_Export" before all global operators
	  to allow them to be dll-exportable on NT.

Mon Jul  8 13:12:05 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/{Message_Block,DEV_IO,SPIPE_Stream}.cpp: Fixed several more
	  cases of delete array that should have been delete [] array.
	  Thanks to Tom Leith for pointing out some of these.  I can hear
	  the ghost of James Mansion coming closer... ;-)

	* INSTALL: Added tips on how to install ACE on a Win32 platform
	  that lacks a network card.

	* ChangeLog: Split ChangeLog-96 into two files (ChangeLog-96a and
	  ChangeLog-96b) since it was becoming quite large!  Thanks to
	  Chris Lahey for pointing this out.

	* ace/Stream.cpp: Was missing a "return 0;" at the end of the
	  close() method.  Thanks to Tom Leith <trl@icon-stl.net> for
	  finding this.

Mon Jul  8 14:20:01 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Time_Value.h: Added "ACE_Export" before all global operators
	  to allow them to be exportable from Win32 DLLs.

Sun Jul  7 10:34:48 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Released version 4.0.27 for testing.

        * config-sunos5.5*.h: Removed all uses of ACE_HAS_SVR4_SIGNAL_T in
	  the config files since Solaris 2.5 has consistent signal and
	  sigaction types (at last!).

        * Installed and compiled ACE successfully with the new SunC++ 4.1
	  compiler on Solaris 2.5.  However, there seems to be major
	  problems with the interaction of the SunC++ exception handling
	  runtime system and the Solaris multi-threading mechanisms.  This
	  is causing the ACE multi-threading tests to bomb with
	  segmentation faults inside of the _ex_unwind() library function.
	  If you read the /opt/SUNWspro_3.1/READMEs/c++ file you'll see
	  why this problem is occurring (apparently due to bugs in the
	  Solaris libC.so.5 C++ runtime library).

	  There seem to be two fixes for this problem:
	  
	  1. Add the following to *all* threads (including main):
	  
	     #include <exception.h>

	     void *my_thread_entry_point (void *) {
	       set_terminate (abort);
	       set_unexpected (abort);

	       // Do real work...
	     }

	     This is the approach recommended by the README file in
	     SUNWspro_3.1.  However, it is *clearly* a horrible hack and
	     very non-portable (therefore, I deem it worthy of Microsoft
	     ;-)).
	  
	  2. Compile ACE (and applications?) with -noex in order to avoid
	     this bug.  This is clearly not desirable either since it
	     precludes the use of exception handling with C++ and threads
	     on Solaris...

	  Since ACE doesn't use exceptions internally on Solaris option 2
          seems like the best approach for the time being.  When Sun gets
          it act together and releases a bug-free library and C++
          software, I'll fix ACE accordingly.

        * tests: Integrated the latest of Prashant's "one-button" tests
	  into the main ACE release.  These will run on both UNIX and
	  Win32 now.

	* ace/UPIPE_Stream.cpp (recv): Changed the semantics of the
	  ACE_UPIPE_Stream::recv (char *, size_t, ACE_Time_Value *)
	  method.  Currently, the behavior is to block until *exactly* N
	  bytes are read.  However, this is incorrect for 2 reasons:

	  1. It makes it hard to write a server that doesn't know
	     precisely how big the messages are from the client.  In
	     particular, if the receiver doesn't know how big the buffer
	     messages are from the client it will block indefinitely!

	  2. It is redundant with respect to the
	     ACE_UPIPE_Stream::recv_n(), which also blocks until all N
	     bytes are received.

	  Therefore, I've made the new UPIPE_Stream::recv() method block
	  only until it's received the first block of data that allows it
	  to fulfill its size request, or anything that is smaller than
	  that size.

	* ace/OS.cpp (thr_create): Since POSIX pthreads doesn't provide an
	  equivalent of THR_NEW_LWP in the pthreads_attr_* functions, I've
	  added an emulation that should work for Solaris.  Basically, if
	  THR_NEW_LWP is set when ACE_OS::thr_create() is called, we use
	  the ACE_OS::thr_{get,set}concurrency methods to increase the
	  number of LWPs by one.  

	* ace/Message_Block: Changed the default high water mark for an
	  ACE_Message_Queue from 4K to 16K.  This is useful since it
	  allows applications to buffer more information before blocking.

	* ace/Log_Msg: Added a pair of operations that allow applications
	  to acquire and release the synchronization lock used internally
	  by the ACE_Log_Msg implementation.  This allows applications to
	  hold the lock atomically over a number of calls to ACE_Log_Msg,
	  which is useful for composite operations like the following:
	  
	  // Make sure the following operations are run atomically!
	  ACE_LOG_MSG->acquire ();

	  while (c != '!')
	    {
	      if (c_stream.recv (&c, 1) == -1)
	        ACE_DEBUG ((LM_DEBUG, 
		           "(%t) buffer recv from supplier failed\n"));
	      else
	        ACE_DEBUG ((LM_DEBUG, "%c", c));
            }

	  ACE_LOG_MSG->release ();

	* examples/IPC_SAP/UPIPE_SAP: Revised all of the UPIPE_Stream
	  tests to make them more consistent and correct with respect to
	  the new changes.

	* ace/Stream.cpp (link_i): There was a bug in the link_i() logic
	  because we weren't also linking the other stream back to our
	  stream.

	* ace/UPIPE_{Acceptor,Connector}: Modified both of these classes
	  so that they don't

	* ace/Stream.cpp (close): Modified close() so that it now detects
	  "double-closes" and ignores anything but the first one.

	* ace/UPIPE_Stream: Updated this class so that it no longer
	  inherits from ACE_Stream (previously ACE_UPIPE_Stream had
	  inherited from *both* ACE_Stream *and* ACE_SPIPE).  There are
	  several reasons we shouldn't inherit from ACE_Stream:
	  
	  1. There are operations on ACE_Stream that don't make any sense
	     on ACE_UPIPE_Stream (e.g., link(), unlink()).

	  2. ACE_Stream isn't really designed to be subclassed (e.g.,
	     it doesn't have virtual methods).

	  3. Not inheriting makes the interface cleaner, e.g., we now use
	     send() and recv() methods consistently, rather than
	     send_msg()/put() and recv_msg()/get().  
	     
          4. The return values from the I/O methods are now more
	     consistent than they were before.

	* ace/Message_Block: The signature for the copy() method was
	  incorrect.  It should have been copy (const char *, .....)
	  rather than copy (char *, ....).

	* examples/IPC_SAP/UPIPE_SAP: Together with Prashant, fixed up the
	  ACE_UPIPE_Stream tests so they more cleverly
	  (and correctly) utilize and illustrate various ACE concurrency
	  features.

Sat Jul  6 18:28:55 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Stream.cpp: Fixed some obscure bugs with Stream::unlink()
	  and Stream::link().  These bugs were triggered by the
	  ACE_UPIPE_Stream tests.  We need to make sure that we don't have
	  race conditions in the order in which ACE_UPIPE_Stream close()
	  down.  Prashant and I fixed this problem by (1) adding a lock to
	  unlink() and link() and then creating unlink_i() and link_i() to
	  perform the work and (2) being more careful about trying to
	  unlink our side and the other side of a linked Stream.

	* ace/config-linux.h: According to Istvan Buki
	  <istvan.buki@infoboard.be>, Linux now supports the
	  send_msg()/recv_msg() system calls, as well as UNIX domain
	  sockets.  Therefore, I've updated the config-linux*.h file to
	  remove the existing restrictions.  If this turns out not to be
	  the case, please let me know.

	* ace/LSOCK.cpp (recv_handle): Added a change to some casts to
	  make ACE compile with Linux.  Thanks to Istvan Buki
	  <istvan.buki@infoboard.be> for reporting this.

	* apps/Gateway/Gateway/File_Parser.cpp (readword): Removed
	  yet another use of:
	  
	  for (int x; foo(x); )
	  {
	  }

	  x = 10;

	  Which is now a deprecated feature of C++.

	* include/makeinclude: added the -lw library to the GNU G++
	  platform*.GNU file in order to pick up the wide-character string
	  functions.

Fri Jul  5 18:11:44 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Re-released version 4.0.26 for testing.

	* ace/CORBA_Handler.cpp (activate_service): Revised the code to
	  use the Orbix macros for TRY/CATCH rather than try/catch.  We
	  need this to make legacy code work!  Thanks to Irfan for
	  pointing this out.

	* ace/Thread_Manager: Fixed a bunch of typos that grelims snuck
          in.  Thanks to Jack Erickson <jack@cibc.com> for reporting this.

	* examples/IPC_SAP/TLI_SAP/ftp-server.cpp: Fixed some typos that
	  were causing problems on AIX.  Thanks to Greg Wilson
	  <gvwilson@vnet.ibm.com> for reporting this.

	* examples/Reactor/Misc/test_time_value.cpp (operator<<): Added a
	  "const" in front of the ACE_Time_Value & in order to make things
	  work correctly on AIX.  Thanks to Greg Wilson
	  <gvwilson@vnet.ibm.com> for reporting this.

	* ace/SPIPE_Acceptor: Fixed some missing "returns" that had sprung
	  up in the #else arm of the SPIPE code.  Thanks to Greg Wilson
	  <gvwilson@vnet.ibm.com> for reporting this.

	* apps/Synch-Benchmarks/Benchmark: Fixed a typo that was causing
	  the application to fail to compile on AIX.  Thanks to Greg
	  Wilson <gvwilson@vnet.ibm.com> for reporting this.

	* Changed all uses of virtual int init (int, char **) to virtual
	  int init (int, char *[]) to workaround bugs with MSVC++...

	* ace/OS.h: for POSIX pthreads, changed the definition of the
 	  THR_SCOPE_SYSTEM macro so that it has the same value as
 	  THR_BOUND.  If this isn't done, then things don't quite work
 	  right when we implement the ACE_OS::thr_create() wrapper.

Thu Jul  4 13:17:35 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Thread_Manager: Added a new method called thr_self() that
	  *does* return a real handle that can be used by
	  WaitForMultipleObjects, etc.  Note that this new approach
	  cleverly caches this handle in TSS in order to cut down on
	  search time.  Thanks to Jesper for pointing this technique out.

	* ace/OS.i (thr_self): After receiving comments from Jesper, undid
	  the earlier change today that was returning a duplicated handle
	  for ACE_OS::thr_self().  It turns out this is a bad idea because
	  the handle most typically doesn't get released, which leads to
	  handle leaks.  

	* ace/Thread_Manager: Added a new private method called
	  check_state().  This method extends existing code to be smarter
	  about how we check to see what "state" (e.g., suspended,
	  cancelled, etc.) a thread is in.  The original code
	  (which was a macro called ACE_CHECK_STATE) didn't behave
	  correctly if we asked about the state of a thread that was
	  different from ourselves!

        * ace/Thread: Modified the public interface to
	  ACE_Thread::spawn_n() so that it now takes a void *stack[] and
	  size_t stack_size[].  If stack != 0 it is assumed to be an array
	  of n pointers to the base of the stacks to use for the threads
	  being spawned.  Likewise, if stack_size != 0 it is assumed to be
	  an array of n values indicating how big each of the
	  corresponding stacks are.  This is useful since now we can spawn
	  a group of threads each of which has its own custom stack and/or
	  stack size.  Thanks to Ashish Singhai
	  <singhai@delirius.cs.uiuc.edu> for pointing out the need for
	  this.

	* apps/Synch-Benchmarks: Updated the Synch benchmarks so that most
	  of them work again.  The trick is *not* to use ACE_OS::sleep ()
	  (which doesn't seem to be thread-friendly...) but instead to use
	  ACE_OS::select() as a timer.

	* man: updated the manual pages and html pages to reflect all the
	  recent changes.

	* ace/Malloc_T.cpp (open): Added a check to make sure that if
	  init_acquire() fails we don't let this go by undetected...
	  Thanks to Karlheinz for pointing out the need for this.

	* ace/OS.i (thr_getconcurrency): Fixed a subtle bug with the
	  ACE_OS::thr_getconcurrency() function.  I was mistakenly using
	  ACE_ADAPT_RETVAL for the result of ::thr_getconcurrency(), which
	  is clearly wrong!

	* ace/Service_Record.cpp (remove): Fixed a typo that was causing
	  the removals of Modules in a dynamically configured Stream to go
	  into infinite loops.

	* ace/OS.i (thr_self): Modified the ACE_OS::thr_self (hthread_t &)
	  function so that it will return a *duplicate* of the current
	  thread's pseudo-handle returned by GetCurrentThread().  This
	  change is necessary because the pseudo-handle returned by
	  GetCurrentThread() is pretty useless (e.g., it can't be used by
	  any other thread to "wait" for this thread to exit).  This new
	  behavior is used in the examples/Reactor/ReactorEx test program.

	* ace/Service_Config.cpp: I'd forgotten to assign the
	  delete_svc_rep_ flag when dynamically allocating the svc_rep_.
	  This is fixed now.

Wed Jul  3 20:09:44 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Added a new subdirectory called $WRAPPER_ROOT/tests that
	  contains the first phase of the ACE regression tests.

	* ace/Reactor.cpp (check_handles): Fixed an earlier fix with the
	  ACE_Reactor::wait_for_multiple_events() method.  The earlier fix
	  had changed the exit condition of do/while loop to be
	  
	  while (nfound == -1 && this->handle_error () >= 0);

	  However, this was causing signal handling to break...
	  Therefore, the right fix is to keep the exit test as:

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

	  and instead fix handle_errors() so that it returns 1 if we're
	  able to fix a bad handle...  Thanks to Prashant and Irfan for
	  tracking this down.

	* ace/OS: Finally broken down and added a new pair of ACE_OS
	  functions called "last_error()".  These basically call
	  SetLastError/GetLastError on Win32 or they set/get errno on
	  UNIX.

	* ace/config-linux.h: Fixed an annoying problem with 
	  struct msghdr in Linux by adding

	  #define msg_accrights    msg_control
	  #define msg_accrightslen msg_controllen

	  to the config-linux*.h files.  Thanks to Michael R"uger
          <m_rueger@syscomp.de> for suggesting this.

	* ace/SOCK_IO.cpp (recv): Fixed a "bug" where
	  ACE_SOCK_IO::{send,recv} allocates with:

	  iovec *iovp = new iovec[total_tuples];

	  But deletes with:

	  delete iovp;

	  Thanks to the ever vigilant James Mansion
	  (mansionj@lonnds.ml.com) for noticing this.

Tue Jul  2 23:48:38 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* ace/Service_Config.h: Added ReactorEx to the singleton resources
	  that the Service_Configurator holds.  This includes accessors,
	  destruction hooks, and event loop methods.

	* examples/Reactor/ReactorEx/README: There is a new example
	  application for the ReactorEx.  Please check out
	  examples/Reactor/ReactorEx/README for details.

Tue Jul  2 18:43:12 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* Released version 4.0.25 for testing.

	* examples/ASX/Message_Queue/priority_buffer.cpp: Added a new test
	  program that illustrates the use of the new Message_Queue
	  priority scheme.

	* ace/Message_Queue: Added new support for prioritized message
	  enqueueing into the ACE_Message_Queue.  Now, when an application
	  uses ACE_Message_Queue::enqueue() the new Message_Block is
	  inserted into the queue according to its msg_priority().  When
	  dequeue_head() is used the item retrieved will then be the item
	  of "highest priority" (priorities range from 0 to MAX_LONG).
	  Note that the semantics of the existing enqueue methods,
	  enqueue_head() and enqueue_tail(), remain unchanged.

	* ace/Message_Block: Changed the type of the priority in a message
	  block to u_long rather than u_char.  This gives us a much
	  greater range of priorities!

Mon Jul  1 01:12:08 1996  Douglas C. Schmidt  (schmidt@tango.cs.wustl.edu)

	* ace/Thread.h: Changed a couple of mistyped comments.  Thanks
	  to the eagle eyes of Andres Kruse for noticing this.

	* ace/OS: added more comprehensive support for UNICODE to
	  both the Win32 and UNIX OS adaptation layer.  This new
	  support automagically selects the appropriate implementation
	  (i.e., either char * or wchar_t *) for the string comparison
	  routines (which are used in places like ACE_Mem_Map).

	* ace/Service_Config: Split up the ACE_Service_Config::close()
	  method into two parts: close_svcs() and close_singletons().
	  This makes it possible to remove svc.conf services without
	  destroying Singletons like the Proactor, Reactor, etc.  Thanks
	  to Karlheinz for recommending this.

	* ace/Service_Config: Added flags for remembering who created the
	  Singleton Proactor, Allocator, Thread_Manager, and
	  Service_Repository (in addition to the Reactor, which I did last
	  week).  If we created these Singletons, then we are responsible
	  for freeing them up.  Thanks to Karlheinz for pointing out the
	  need for this.

Mon Jul  1 16:26:27 1996  Prashant Jain  (pjain@merengue.cs.wustl.edu)

	* ace/Connector.cpp: Added two new arguments to connect () namely,
	  "int flags" and "int perms". The Connector can now pass these
	  two arguments to its template arguments (e.g., SOCK_Connector,
	  SPIPE_Connector, etc.) when calling their connect() method.  A
	  consequence of doing this was that we had to modify the
	  signature of the connect() method on some of the IPC_SAP classes
	  (e.g., TLI_Connector, SOCK_Connector, and LSOCK_Connector).  
	  Note that these changes may break some existing code,
	  particularly with TLI_Connector (see below), so beware...

	* ace/TLI_Connector.cpp: Changed the order of the connect()
	  arguments to be more consistent with the rest of the IPC_SAP
	  classes used with the Connector.  Please note that existing
	  examples which use TLI_Connector may need to be modified as a
	  result of this change.

	* ace/OS.i (open): Modified ACE_OS::open() to use the argument
	  perms to turn the flag FILE_FLAG_OVERLAPPED on and off for
	  Win32.

	* ace/Service_Config.cpp (end_proactor_event_loop): Added new
	  methods run_proactor_event_loop() and end_proactor_event_loop()
	  which call handle_events on the Proactor.

Mon Jul  1 02:15:34 1996  Tim H. Harrison  (harrison@lambada.cs.wustl.edu)

	* ace/Proactor.h: Made ACE_Proactor an ACE_Event_Handler so that
	  it can be registered with the ACE_ReactorEx.  ACE_Proactor
	  associates the same global HANDLE with every overlapped I/O
	  operation.  This global HANDLE can be registered with the
	  ACE_ReactorEx.  Therefore, by using the
	  ACE_Proactor::handle_signal method as an adapter, we can now
	  dispatch overlapped I/O and other "waitable" objects from a one
	  ACE_ReactorEx running in a single thread of control.  Thanks to
	  James Mansion <mansionj@lonnds.ml.com> for setting us on the
	  right path!

	* ace/ReactorEx.h: Added a ACE_ReactorEx to encapsulate Win32
	  WaitForMultipleObjects().  The ACE_ReactorEx handle_events()
	  method calls ACE_Event_Handler::handle_signal when the
	  corresponding Win32 HANDLE becomes signaled.  This gives us a
	  uniform abstraction for dispatching all "waitable" objects on
	  Win32, including events related to I/O completion ports and
	  events related to other forms of NT synchronization (such as
	  mutexes, semaphores, threads, etc.).

	* ace/Timer_Queue.h (calculate_timeout): Added a calculate_timeout
	  method to ACE_Timer_Queue.  Also removed the same method from
	  ACE_Reactor.  This is so Reactor, ReactorEx, and Proactor can
	  all reuse the calculations required by the Timer_Queue without
	  duplicating code.
