Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.i (cond_timedwait): Fixed the implementation of the - ACE_OS::cond_timedwait() wrapper such that if the - caller-specified timeout elapses without the condition variable - being signaled that errno is always set to ETIME. This fixes - some inconsistencies that occurred with POSIX pthreads and Win32 - threads. Thanks to Ross Dargahi <rossd@acm.org> for pointing - this out. - - * ace/SOCK.cpp: Changed SOCK::close() to use the new - ACE_OS::closesocket() call. This should fix some weird bugs - that have been lurking in the code for some time now! - - * ace/OS: Added a new method to ACE_OS called closesocket(). This - handles the differences between Win32 and UNIX in their - treatment of sockets (e.g., NT requires the use of - closesocket(), whereas UNIX requires the use of close(). Thanks - to Irfan, Prashant, and Tim for figuring this one out! - -Sat Jun 29 21:23:04 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/SPIPE_Acceptor.cpp (create_new_instance): Added the flag - (FILE_FLAG_OVERLAPPED) in call to CreateNamedPipe. - -Fri Jun 28 01:31:24 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Svc_Handler.cpp (open): Fixed a small typo that caused a - compile error if the DEBUGGING macro was enabled. Thanks to - Irfan for finding this. - -Wed Jun 26 03:19:27 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Synch_T.cpp (ts_get): The tss object allocated off the heap - should be released if setspecific fails. Thanks to John Lu - <johnlu@f1.telekurs.ch> for reporting this. - - * ace/CORBA_Handler.cpp (handle_input): changed ACE_OS::send and - ACE_OS::recv to ACE::send and ACE::recv respectively in - CORBA_Handler.cpp. Thanks to Irfan for pointing this out. - - * ace/Service_Config: slightly modified the Service_Config.[h,cpp] - in order to make it possible to create an ACE_Service_Config - with an external ACE_Reactor as a parameter. On creation I was - handling this partly correct (i.e., not creating a new reactor). - However, there was no flag for remembering this for a later - deletion. Thus, on deletion I was doing a delete on the Reactor - regardless of who created it. This is now fixed. Thanks to - Karlheinz for pointing this out. - - * examples/ASX/CCM_App/CCM_App.cpp: Changed all uses of init (int, - char **) to init (int, char *[]) to work around a "feature" with - MSVC++ 4.x... Thanks to Karlheinz for pointing this out. - - * ace/OS.h: Added a new typedef of TCHAR to be compatible with - Win32 UNICODE type names... - - * ace/{Mem_Map,DEV_Addr,SPIPE_Addr,FILE_Addr}: Added UNICODE - support for Win32 to all interfaces that require filenames. - - * ace/{SPIPE_Stream,SOCK_IO,FILE_IO,DEV_IO}: Added a new pair of - send()/recv() methods that take ACE_OVERLAPPED pointers in order - to make it possible to integrate seamlessly with Win32 - overlapped I/O. Naturally, these methods are simply - "callthroughs" to the ACE_OS versions... - - * ace/OS: Added a new pair of send()/recv() methods that take - ACE_OVERLAPPED pointers in order to make it possible to - integrate seamlessly with Win32 overlapped I/O. - - * ace/SPIPE_Acceptor: Factored out common code in the Win32 - implementation of ACE SPIPES (which uses Win32 Named Pipes, of - course ;-)). - - * ace/SPIPE_Acceptor.h: Removed a vestige of the past -- - ACE_SPIPE_LISTENER_H should be ACE_SPIPE_ACCEPTOR_H... - -Wed Jun 19 19:35:12 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/SPIPE_{Acceptor,Connector}: Modified SPIPE_Acceptor and - SPIPE_Connector to implement Named Pipes on NT. The public - interface remains the same. - -Sun Jun 16 00:45:41 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Service_Config: Provided public accessor methods for the - following data memebers of the ACE_Service_Config: - - reconfig_occurred_ - end_event_loop_ - - Thanks to Steve Warwick <sjw@aesthetic.com> for suggesting this. - - * ace/Synch*: Added UNICODE support for the ACE synchronization - classes (e.g., ACE_Mutex, ACE_RW_Mutex, ACE_Semaphore, etc.). - - * ace/OS: Added UNICODE support for the ACE_OS::dl_open() - function, as well as the ACE_OS synchronization functions. - - * ace/CORBA_Handler: Added Seth's changes for Orbix 2.0. - -Sat Jun 1 13:30:55 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Memory_Pool.cpp (remap): Fixed a bug in - ACE_MMAP_Memory_Pool::remap (). The test for whether or not the - addr falls within the range had a '!' (not) missing, that is, it - was failing when it should be succeeding and vice versa. - -Sun Jun 9 00:01:44 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.24 for testing. - - * ace: Changed all uses of ACE_Guard<LOCK> m (lock_) to ACE_GUARD - (LOCK, lock_), which is a macro that is defined as follows: - - ACE_Guard<MUTEX> ace_mon (LOCK); \ - if (m.locked () == 0) return; - - The reason we need this is (1) detect locking failures, rather - than have things fail silently and (2) to automatically detect - deadlock in the Reactor. In addition, I also added - ACE_GUARD_RETURN, which is similar to ACE_GUARD, except that it - returns a "failure" status when the lock is not acquired. - Thanks to Karlheinz for suggesting this. - - * ace/Log_Msg: Added the new thr_state() accessors to Log_Msg. - - * ace/Thread_Manager.cpp: factored out some common code by having - the public interfaces (like resume() and suspend()) utilize the - protected interfaces (like resume_thr() and suspend_thr()). - - * ace/Thread_Manager.cpp: Added sanity checks for suspend(), - resume(), cancel(), etc. so that we don't blow up if someone - tries to perform an operation on an invalid thread id. - - * ace/Thread_Manager: Added a suite of new methods for - (1) cooperatively "canceling" threads and (2) testing if threads - are cancelled (also added similar checks to test if threads are - suspended or resumed). The cooperative cancellation mechanism - is based on a design fleshed out with Detlef and Karlheinz. - It's essentially a compromise between the powerful mechanisms - available via POSIX pthreads vs. the totally lame mechanisms - available in Win32. - - Here's how it all works: - - 1. Added several new methods to ACE_Thread_Manager: - - cancel(thr_id); -- cancels thr_id - cancel_all(); -- cancels all the threads in a Thread_Manager - cancel_grp(grp_id); -- cancels a group of threads in a Thread_Manager - testcancel(thr_id); -- returns "true" if thr_id has been cancelled - - 2. Updated ACE_Log_Msg to maintain the current state of a thread - in thread-specific-storage (TSS). Actually, it's more clever - than that since I really keep a *pointer* to the state of a - thread in TSS. This pointer actually points *back* to the - ACE_Thread_State field in the ACE_Thread_Manager! I use it - as a cache as follows: - - ACE_Thread_Manager::testcancel (thread_t t_id) - { - ACE_MT (ACE_Thread_Mutex_Guard m (this->lock_)); - - // Try to get the cached value out of TSS to avoid lookup. - ACE_Thread_State *thr_state = ACE_LOG_MSG->thr_state (); - - if (thr_state == 0) - { // We need to init the cache. - int i = this->find (t_id); - if (i == -1) return -1; - // Update the TSS cache. - ACE_LOG_MSG->thr_state (thr_state = &this->thr_table_[i].thr_state_); - } - return *thr_state == ACE_THR_CANCELLED; - } - - Note that this allows me to avoid searching the - Thread_Manager on every Thread_Manager::cancel() access - except the first one! - - 3. I've updated the examples/Threads/test_thread_manager.cpp - test file to exercise the new cooperative thread cancellation - scheme. It basically spawns a bunch of threads that go into - their own event loops doing - - if (thr_mgr ()->testcancel (ACE_Thread::self ()) != 0) - break; - - every so often. Naturally, the main thread cancels them by saying - - thr_mgr ()->cancel_grp (grp_id); - - when it wants to inform them to shut down. - - * ace/Thread_Manager: Moved the Thread_State enum from the - ACE_Thread_Descriptor class to OS.h and renamed it to be - ACE_Thread_State. This will make it easier to integrate the - state of a thread in thread-specific storage... - -Sat Jun 8 13:35:17 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.i (sema_post): revised the implementation of the POSIX - Pthreads semaphore implementation just a bit in order to make it - slightly more efficient (it now releases the mutex before - signaling the condition variable). - - * ace/OS.i and config-aix.4.1.h: added a fix that separates the - decision about whether optlen is a pointer from the decision of - the type of optlen. This fixes a problem on AIX. Thanks to Bob - Olson <olson@mcs.anl.gov> for this fix. - - * ace/Proactor.h: Fixed a small glitch that was causing some - compilers to break due to the fact that they can't grok fully - qualified destructor syntax in the class definition. Thanks to - Alfred Keller <kellera@pop.eunet.ch> for reporting this. - - * ace/OS.h: Added some Win32 macros (e.g., GENERIC_READ) to the - UNIX side of the house in order to compile the Proactor on Win32 - and UNIX. - -Fri Jun 7 19:36:27 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added a new Bourne shell script called ACE-install.sh that will - automatically download and install on UNIX machines. Thanks to - Ajit Sagar <asagar@spdmail.spd.dsccc.com> for contributing this. - -Thu Jun 6 00:37:02 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.23 for testing. - - * ace/Local_Tokens: Updated the *.cpp and *.i files to remove - warnings and generally improve the conformance to the ACE coding - guidelines. - - * examples: Moved the Proactor directory into the Reactor - directory since the Proactor and Reactor are really two - implementations of the same basic pattern. - - * ace/Memory_Pool.cpp: Fixed an inconsistency caused by not - updating __INLINE__ to __ACE_INLINE__. Thanks to Neil Cohen for - finding this. - - * ace: Added support for the Florida State PTHREADS package. - Thanks to Gary Salsbery <gsalsber@simsun.atsc.allied.com> and - Eric Beser <beser@simsun.atsc.allied.com> for helping with this. - - * ace: Added support for the m88k OS. Thanks to Gary Salsbery - <gsalsber@simsun.atsc.allied.com> and Eric Beser - <beser@simsun.atsc.allied.com> for helping with this. - - * ace/OS.h: Added a default value of NULL to the sigwait() OS - wrapper method to simplify the usecase in certain cases. - - * ace/Memory_Pool.cpp (commit_backing_store): Fixed what is - hopefully the last typo related to the ACE_DEFAULT_BASE_ADDR - macro. Thanks to Neil B. Cohen <nbc@metsci.com> for reporting - this. - -Thu Jun 6 15:31:40 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * ace/CORBA_Handler.h: This version of the CORBA_Handler works - with Orbix 2.0. Most of the changes involve the use of C++ - Exception Handling (the removal of IT_X), and the location of - some CORBA system exception classes. - - * ace/Event_Handler.h: Added handle_*_complete methods for the - Proactor. The Proactor now takes Event_Handlers and calls back - the **_complete methods when overlapped I/O operations have - completed. - - * ace/Service_Config.h: Added static accessors for the Proactor to - the Service_Config object. Similar to the Reactor accessors, - applications can now use the Service_Config object as the global - access point to the Proactor event demultiplexor. - -Wed Jun 5 22:40:28 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.i (t_free): Added a check to avoid deleting a NULL ptr. - This was causing problems for the TLI_Acceptor. Thanks to Ajit - Sagar <asagar@spdmail.spd.dsccc.com> for reporting this. - - * ace/Makefile: Changed things back so that both static and - dynamic libs are built by default... Thanks to Brad Brown - <bbrown@rdxsunhost.aud.alcatel.com> for pointing this out... - -Sat Jun 1 13:49:51 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.22 for testing. - - * Added Tim Harrison's latest tests for Proactor. - -Sat Jun 1 13:30:55 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Memory_Pool.cpp (remap): Fixed a bug in - ACE_MMAP_Memory_Pool::remap (). The test for whether or not the - addr falls within the range had a '!' (not) missing, that is, it - was failing when it should be succeeding and vice versa. - -Fri May 31 16:31:13 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Rereleased version 4.0.21 for testing. - - * Copied over new versions of the Proactor -- there was a small - problem with the UNIX version that caused it not to compile... - -Fri May 31 00:03:41 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * examples/Proactor/test_proactor.cpp: Added a test program for - the Proactor. Check examples/Proactor/README for more details - on this test example. - - * ace/Proactor.cpp: Added first pass at the Proactor for win32. - The Proactor is a Reactor-like abstraction that uses - asynchronous I/O, rather than synchronous I/O. On Windows NT we - implement the Proactor using overlapped I/O. We'll soon be - porting the Proactor to Solaris using POSIX 4.x aio_* API for - real-time programming. - - Unfortunately, the Proactor has not yet been integrated with - Windows NT WaitForMultipleObjects since it appears that I/O - Completion ports are not "waitable" objects on Windows NT. Does - anyone know if this has been fixed in release 4.0? - -Thu May 30 05:51:23 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Synch.i: Reordered the definitions of several methods in - Synch.i to avoid warnings from G++. Thanks to Marco Sommerau - <sommerau@matisse.informatik.uni-stuttgart.de> for noticing - this. - - * ace/Log_Msg.cpp: There was a problem having to do with the order - in which static objects by G++. In particular, G++ was calling - the constructor of the lock_ mutex in Log_Msg.cpp *after* it was - being used for the first time. The right solution is to make - lock_ be a pointer and allocate it once in the instance() - method. Thanks to Marco Sommerau - <sommerau@matisse.informatik.uni-stuttgart.de> for finding this - problem. - - * ace/TLI_Acceptor.cpp (close): Make sure to only close down the - TLI_Request_Queue if queue_ is non-NULL! Thanks to Ajit Sagar - <asagar@spdmail.spd.dsccc.com> for spotting this. - - * ace: Changed all the enums in the various SysV wrappers from - things like CREATE and OPEN to ACE_CREATE and ACE_OPEN to avoid - name clashes with other systems. In addition, also changed - NONBLOCK to ACE_NOWAIT to avoid clashes with the existing - ACE_NONBLOCK macro! Thanks to Steve Warwick <sjw@aesthetic.com> - for suggesting this. - - * ChangeLog: Changed all usages of the INLINE macro to ACE_INLINE. - This avoids name clashes with other systems. Thanks to - Chris Eich <Chris_Eich@optilink.optilink.dsccc.com> for - suggesting this. - -Mon May 27 13:03:58 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Map_Manager.cpp (trybind): The function trybind() doesn't - return a value as it should. A return was missing from the last - line of the function. Thanks to Stuart Powell - <stuartp@in.ot.com.au> for finding this problem. - - * ace/Acceptor.cpp (dump): The debug print referred to - "scheduling_strategy_" which doesn't exist in the relevant - class. Replacing it with "concurrency_strategy_" fixes the - problem. Thanks to Stuart Powell <stuartp@in.ot.com.au> for - finding this problem. - - * ace/Mem_Map.i: Make sure to close down the file mapping - correctly when we upmap the view! - - * ace/OS.h: Changed the default shared memory address from 16 M to - 64 M in order to work around problems with AIX. - - * ace/Memory_Pool: Moved and renamed the enums in - ACE_Shared_Memory_Pool so that they'd be in OS.h. This makes it - easier to remember to change them if they are incorrect. Thanks - to Lionel Mommeja <mommeja@vnet.ibm.com> for suggesting this. - - * ace/Stream.cpp: Removed #if defined (ACE_HAS_THREADS) - - * ace/OS.cpp (svc_run): Added a Win32 try/except block to - Spawn_Args::svc_run so that we catch all Win32 structured - exceptions in order to make sure that we clean up correctly when - the thread exits. - -Sun May 26 11:37:08 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Local_Name_Space.cpp: Used the new Win32 exception - integration in order to ensure that the Name Server will - transparently work correctly when the backing store is extended - by other processes on the same machine. - - * ace/Memory_Pool.cpp: Revised the ACE_MMAP_Memory_Pool to export - the mechanism for extending the virtual memory mapping. This - can now be called by other programs (e.g., in order to integrate - with Win32 Structure Exception Handling). - - * ace/Memory_Pool.cpp: Changed the use of ACE_OS::lseek() to - ACE_OS::filesize() in order to determine the current offset when - we're remapping the address space. - -Wed May 22 13:08:44 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/OS.h (ACE_DEFAULT_TIME_SERVER_STR): Added a new entry for - ACE_DEFAULT_TIME_SERVER_STR. - - * ace/Malloc_T.cpp (advance): Fixed two small bugs. In - ACE_Malloc::try_bind(), if we have a match we need to set - pointer to node->pointer_ and not node->name_. - Ina ACE_Malloc_Iterator::advance(), the continue in the for loop - should be for strcmp != 0 instead of == 0. - -Sun May 19 12:03:11 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.20 for testing. - - * ace/Service_Record.cpp (remove): Fixed a very mysterious bug - that was caused by deleteing an object and then trying to access - it's next_ pointer. This worked on UNIX, but fortunately the - MSVC++ compiler does special things to deleted memory and the - bug was revealed! At long last, MSVC++ does something right - ;-). - - * ace/Module.cpp: Revised the code a bit to use the ACE_SET_BITS - and ACE_CLR_BITS macros to improve readability. - - * ace/SV_Semaphore_Complex.cpp (open): Fixed a race condition - where we weren't correctly checking for EIDRM. Thanks to - Michael Fortinsky <mike@vocaltec.com> for reporting this. - -Sat May 18 10:49:04 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Added a new ace.mak and ace.mdp file for Win32. - - * ace/Service_Record.cpp: Rewrote some code to work around a bug - with MSVC++. This bug was causing problems since the - ACE_Shared_Object methods were getting called, rather than the - Test_Task methods used in the examples/ASX/CCM_App.cpp file. - Thanks to Tom Leith for pointing out this problem! - - * ace/OS.h: Added a new #define for ACE_DEFAULT_SVC_CONF to deal - with differences between NT and UNIX pathnames. - - * ace/Time_Value.h: Moved the definition of the INLINE macro from - OS.h to Time_Value.h so that it will be in scope for - Time_Value.i. Thanks to Neil Cohen for reporting this. - - * examples/Reactor/Misc/signal_tester.cpp: There was a typo in - signal_test.cpp. It had mean to use handle_input() rather than - handle_output() to exercise the asynchronous signal handling - capabilities. This is fixed now. - - * apps/Synch-Benchmarks/Benchmark.cpp (thr_id): Added a new #if - define (ACE_HAS_DCETHREADS) to make this work on AIX. Thanks to - Greg Wilson <gvw@cs.toronto.edu> for reporting this. - - * ace/Local_Name_Space: Moved ACE_NS_String and ACE_NS_Internal - from the *.cpp file to the *.h file to work around a "feature" - of the AIX C++ compiler. Thanks to Greg Wilson - <gvw@cs.toronto.edu> for reporting this. - - * ace/Reactor.h (ACE_Handler_Repository): Changed the type of - cur_size_ from size_t to ssize_t to avoid type mismatches. - - * ace/Name_Request_Reply.cpp (decode): Fixed some inconsistencies - between signed and unsigned loop counters... - - * ace/OS.h: Changed the typedef of pid_t on Win32 from - DWORD to long to be consistent with UNIX. - -Thu May 16 18:49:14 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.19 for testing. - - * build/SunOS5.4/ace/ACE.cpp (ldfind): Fixed a bug in ldfind() - that caused a segfault if we didn't resolve the filename in the - LD_SEARCH_PATH. - - * ace/Reactor and Timer_Queue: Changed the interface of cancel() - to include a const void **arg. If arg is non-NULL then it will - be set to point to the ``magic cookie'' argument passed in when - the Event_Handler was registered. This makes it possible to - free up the memory and avoid memory leaks. - - * ace/Service_Record: Removed the #ifdefs that checked if - ACE_HAS_THREADS because we ought to be able to build all of this - stuff now that we've got the ACE_OS wrappers. - - * ace/Svc_Conf.y: Removed the #ifdefs that checked if - ACE_HAS_THREADS because we ought to be able to build all of this - stuff now that we've got the ACE_OS wrappers. - - * ace/OS.h (ACE_DEFAULT_BACKING_STORE): Made a different - ACE_DEFAULT_BACKING_STORE for NT and for UNIX to handle the - differences in directory separator characters... - -Wed May 15 18:45:48 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * examples/ASX/CCM_App/CCM_App.cpp: Fixed up the test application - so that it should support dynamic linking on Win32. Thanks to - Tom Leith for reporting this. - - * ace: Added the ACE_Export macro to class ACE and the various - "helper" classes related to ACE_Malloc in order to have this - work properly when use with ACE_Malloc outside of the ACE DLL. - - * ace/Svc_Conf.l: Added support for '\' and ':' in the regular - expression for an ACE pathname in order to support Win32 - filenames (e.g., "C:\foobar\"). Thanks to Tom Leith - <trl@icon-stl.net> for reporting this. - - * ace/Malloc_T.cpp (ACE_Allocator_Adapter): Moved the constructor - from the *.i file to the *.cpp file and added a new constructor - that takes both a pool_name *and* a lock_name. This is - necessary because the ACE Malloc now has this API, as well. - - * examples/Threads/test_barrier.cpp (main): Fixed a bug that was - caused by the main() thread exiting before all the other worker - threads had finished "waiting" on their Barrier. The fix is to - use ACE_Thread_Manager to control the thread exits... - -Mon May 13 00:03:09 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * examples/Connection/non_blocking/CPP-acceptor.cpp: Modified the - implementation of the Svc_Handler::open() method so that it will - truly behave as an iterative server (as advertised...). - Currently, it behaves as a half-iterative server (i.e., the - Oneshot_Acceptor is iterative, but the Svc_Handler is - "concurrently"), which is causing problems because we're wiping - out the values of Svc_Handler each time through the main event - loop. Thanks to Gerolf Wendland for noticing this problem. - - * ace/Log_Msg: Added an alternative logging mechanism that makes - it possible to integrate variable argument lists from other - logging mechanisms into the ACE mechanism. Thanks to Chris - Lahey for proposing this. - - * ace/Synch.h: Moved ACE_Process_Mutex so that it appears *after* - ACE_Mutex (since it depends on ACE_Mutex). Thanks to Dieter - Quehl for finding this. - - * Released version 4.0.18 for testing. - - * ace/Name_Space.cpp: Added the ACE_BUILD_DLL macro at the - beginning of this file so that it will build as a DLL on NT - correctly. - - * ace/Name_Space.cpp: Added a default constructor for - ACE_Name_Binding so that it will compile when used as a template - argument for ACE_Unbounded_Set. - -Sun May 12 14:23:44 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Map_Manager: Totally reworked the Map Manager so that it can - be more flexible with respect to where the allocator comes from. - This is necessary for certain parts of ACE (e.g., - Local_Name_Space) that must be very careful about which - allocator is used to manage memory. - - * ace/Synch: Moved ACE_Process_Mutex and ACE_RW_Process_Mutex - *outside* of the ACE_HAS_THREADS #ifdef since these are now - always defined on all platforms (because the Process_Mutex stuff - uses SV Semaphores, which are portable even if we don't have - threads!). - - * ace/Naming_Context.cpp (parse_args): Removed an unnecessary call - to strdup(). This was detected by Purify! - -Sun May 12 14:26:20 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Local_Name_Space.cpp (shared_bind): Fixed a small bug. In - computing type_len in shared_bind(), we needed to add 1 to - account for the NUL character. - - * ace/Local_Name_Space.cpp: (list_types): Fixed some potential - memory leaks. In list_types() as well as list_type_entries() - calling pattern.char_rep() was allocating memory which was never - getting deleted. Similarly, in list_names() and list_values, - call to char_rep was also allocating memory that was not getting - deleted. - -Sat May 11 16:19:51 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Log_Msg.cpp (local_host): added a static member to - ACE_Log_Msg that maintains the local host name. Now, instead of - always displaying "<local host>", we can insert the actual local - name into the object and then it will be automatically printed - when VERBOSE mode is enabled. Thanks to Chris Lahey for - suggesting this. - - * ace/Local_Name_Space.cpp: Used the new ACE_Name_Binding class to - simplify the implementation of all the list_* methods in - ACE_Local_Name_Space. - - * ace/Name_Space.cpp: Made a number of changes to the - ACE_Name_Binding class in order to make it work more efficiently - and concisely (e.g., reduce the amount of copying and eliminate - the need for converting the type field back and forth to/from - ACE_WStrings). - - * examples/Service_Configurator/IPC-tests/server/Handle_L_Dgram.cpp: - Fixed a typo where #if !defined (ACE_LACKS_UNIX_DOMAIN_SOCKETS) - was *before* the #include of the header file that defines this - macro! Thanks to Nigel for pointing this out, as well. - - * ace: Added a number of fixes to make ACE compile on SCO UNIX - 3.2.4 using gcc 2.7.2. Thanks to Nigel Lowe <nigel@nt.com> for - helping with this. - - * netsvcs/lib/Name_Handler.cpp: operation_ needs to be declared as - just LIST_OP and not ACE_Name_Handler::LIST_OP. For some strange - reason NT complains otherwise. Thanks to Prashant for finding - this. - -Fri May 10 01:09:17 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Added new versions of ace.mak and ace.mdp to fix a couple - of minor typos. - - * ace/Malloc_T.cpp (ACE_Malloc): Added a new constructor that - takes both the pool_name and the lock_name explicitly. This is - more flexible. Thanks to Ramesh Nagabushnam <rcn@nynexst.com> - for suggesting this. - - * ace/Malloc_T: Modified the constructor of ACE_Malloc so that by - default the name of the memory pool (which is also used as the - name of the lock...) is ACE_DEFAULT_MUTEX. - - * Released version 4.0.17 for testing. - - * ace/Connector.cpp (create_AST): Must reset errno = EWOULDBLOCK - to avoid making caller's think that something else has gone - awry... Thanks to Steve Warwick <sjw@aesthetic.com> for chasing - this down! - - * ace/ACE.cpp (handle_timed_complete): If you issue a non-blocking - connect on a socket, you will have back a failure with errno = - EINPROGRESS. Then, if for some reason, the connection could not - be established, the select (which you have to issue to know - about the completion of connection) will return you the fd set - both in the read mask and in the write mask (infact select - returns 2 in this case). The behaviour above affects the method - ACE::handle_time_complete, so I changed the last part of the - above method, this way: - - if (n <= 0) - { - ... - ... - } - else if (rd_handles.is_set(h)) - { - char dummy; - // The following recv() won't block provided that the - // ACE_NONBLOCK flag has not been turned off . - - if (ACE::recv (h, &dummy, 1, MSG_PEEK) <= 0) - return ACE_INVALID_HANDLE; - } - - // 1. The HANDLE is ready for writing or 2. recv() returned that - // there are data to be read thus the connection was successfully - // established. - return h; - - That is, I reversed the sense of the tests so that the - rd_handles() is checked first for failure along with the recv(). - Thanks to Antonio Tortorici <antonio@rh0011.roma.tlsoft.it> for - suggesting this. - - * examples/Threads/test_thread_manager.cpp (main): Changed argv[1] - to argv[2]. Thanks to Andres Kruse <kruse@cern.ch> for finding - this problem. - - * examples/Connection/non-blocking: Fixed some nasty bugs that - caused the non-blocking connector and acceptor test programs to - crash and burn. Thanks to Steve Warwick and Gerolf Wendland for - finding this problem. - - * ace/SV_Semaphore_Simple.cpp (open): Check for - ACE_INVALID_SEM_KEY and return -1 in this case. - - * ace/Synch.h: Removed the default value of 0 for the name of the - ACE_Process_Mutex and the ACE_RW_Process_Mutex and replaced it - with a new macro called ACE_DEFAULT_MUTEX. Using 0 didn't make - any sense on either NT or UNIX because process-wide Mutexes - should be named! - - * ace/SV_Semaphore_Simple.cpp (name_2_key): Added a check for name - == 0 and bail out of that's the case rather than crash! - - * ace/Reactor.cpp (wait_for_multiple_events): In the Reactor's - wait_for_multiple_events method, the do {} while () around the - select/poll system call is trying to wait until some "good" - event occurs, with handle_error() taking care of unexpected - problems. In the case of a bad file descriptor, however, - handle_error() returns 0. This was exiting the loop because the - loop exit condition was: - - do { /* ... */ } while (nfound == -1 && this->handle_error () > 0); - - which eventually causes ACE_Service_Config::run_event_loop() to - exit. Since the offending file descriptor is handled by - handle_error(), the loop should continue. Therefore, I've - changed the while to read: - - while (nfound == -1 && this->handle_error () >= 0); - - Thanks to Eric C. Newton <ecn@clark.net> for providing this fix. - - * ace/INET_Addr.cpp (string_to_addr): Changed the order of the - parameters so that the form is now "ip-address:port". This - should (finally) be consistent for both string_to_addr() and - addr_to_string()... - - * ace/Log_Msg: Changed the char * parameter of the log() method to - const char *. Thanks to Chris for suggesting this! - - * ace/Synch_T.cpp: Moved the #if defined (ACE_HAS_THREADS) down to - the right part of the file... Thanks to Alex Karev - <akg@na47sun05.cern.ch> for finding this. - - * ace/Malloc.h: Added a very important #else... Thanks to Alex - Karev <akg@na47sun05.cern.ch> for finding this. - - * ace/Signal.i (ACE_Sig_Guard): Changed the sense of the #ifdef - tests in the ACE_Sig_Guard constructor and destructor from #if - !defined (ACE_MT_SAFE) to #if 0 // !defined (ACE_MT_SAFE) in - order to get the right semantics for signals (which should be - blocked "process wide"). - - * ace/Synch_T.h: put the frigging copy constructor in the public - section of ACE_Atomic_Op because it was causing trouble for - NT... - -Mon May 6 00:11:37 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.16 for testing. - - * ace/Log_Msg.cpp: Was defining ACE_Recursive_Thread_Mutex in the - wrong place (i.e., outside of the #if defined (ACE_MT_SAFE). - This was screwing up HP/UX. Thanks to Neil Cohen for pointing - this out! - - * Incorported new versions of ace.mdp and ace.mak for Win32. - -Sun May 5 16:18:43 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * netsvcs/lib/Server_Logging_Handler.cpp (handle_input): Fixed a - bug whereby handle_input() was returning the number of bytes - read by handle_logging_record() rather than 0 or -1. This was - causing problems for the logger since it was hanging in read()! - - * ace/Synch_T.cpp: Fixed some minor problems with the use of const - in ACE_Atomic_Op that was causing warnings. - -Sat May 4 16:31:46 1996 Douglas C. Schmidt (schmidt@mambo.cs.wustl.edu) - - * ace/SOCK_Dgram_Bcast: Reimplemented most of the ACE socket - broadcast mechanism to (1) clean up the code and have it use - other parts of ACE and (2) make it work for Windows NT. Thanks - to Steve Weismuller <spweismu@rsoc.rockwell.com> for the basic - ideas here. - - * ace/INET_Addr: Added a new method to set the port number without - changing the host address. This is useful in the broadcast - class. - - * ace/Log_Record.cpp (print): Changed the hack of replacing the - newline with a call to flush() instead. This seems like a - better fix. Thanks to Alex for suggesting it. - - * ace/Log_Msg.cpp (log): Moved the order of the print operations - so that the ostream one goes last. This avoids a nasty problem - due to the fact that it replaces the newline (if any). Thanks - to Alex for pointing this out too! - - * ace/Log_Msg.cpp (log): Don't auto-increment bp at the end of - the log() method, instead just terminate it: - - *bp = '\0'; // Terminate bp. - - This makes the length computation correct... Thanks to the - ever-vigilent Alexandre Karev <akg@na47sun05.cern.ch> for - reporting this. - - * examples/Shared_Malloc/test_malloc.cpp: Fixed a bug where a void - * that was really an int was being cast incorrectly. Thanks to - Raj for pointing this out. - -Sat May 4 12:51:25 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Reactor.cpp (find): Modified the ACE_Handler_Repository so - that it doesn't crash when it isn't initialized properly. - Thanks to Darrin for pointing this out. - - * ace/Synch_T.cpp (wait): Changed the call wait(ACE_Time_Value *) - to wait(const ACE_Time_Value *) since wait() will not change the - time value object. - - * ace/Thread_Manager.cpp (wait): Changed the call - wait(ACE_Time_Value *) to wait(const ACE_Time_Value *) since - wait() will not change the time value object. Thanks to Chris - Lahey for suggesting this. - - * ace/Synch.h: Added a (const char * = 0) argument to - ACE_Null_Mutex so that it would work correctly with - ACE_Thread_Mutex and ACE_Process_Mutex... - -Fri May 3 17:26:07 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * netsvcs/lib/Name_Handler.cpp (lists_entries): Used '_' with - name/value/type in ACE_Name_Binding to be consistent with the - notation. - -Fri May 3 02:24:19 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Synch: Updated ACE_Process_Mutex to use SV_Semaphore_Complex - as the UNIX implementation. This seems like the only portable - and robust way to get the same semantics on UNIX and on NT! - - * ace/Malloc_T: It turned out there was a subtle bug with - ACE_Malloc on NT when used with the ACE_Process_Mutex - concurrency policy. On NT, we were storing the *HANDLE* of a - mutex in shared memory. Naturally, this didn't make any sense - since each HANDLE is relative to only one process!!! (duh ;-)). - This worked fine on UNIX because mutex_t's created with - USYNC_PROC mode can be stored in shared memory and accessed - directly... - - We fixed this by changing ACE_Malloc so that the - LOCK is allocated in non-shared memory. We then - fixed ACE_Process_Mutex so that on UNIX it is - implemented with SV_Semaphore_Complex. This is - (a) portable and (b) it gives the right semantics. - - As a result, we were able to totally eliminate the storage of - the lock in shared memory. Therefore, it doesn't matter of the - host crashes anymore! In addition, we were able to totally - remove the ugly "init_finished" lock that was previously stored - in shared memory by ACE_MMAP_Memory_Pool. This is *much* - cleaner!! - - Thanks to Karlheinz et al for pointing this problem out in the - first place! - - * ace: Removed a stray file called Svc_Conf_tokens.h. This was - causing problems on Win32 due to name clashes... Thanks to Adam - Miller for pointing this out. - - * ace/SString.cpp (strstr): there were some for (size_t j; ...) {} - if (j == x) constructs in the code that have as of recently - become non-standard. Thanks to Darrin <darrin@jeeves.net> - for reporting this. - -Tue Apr 30 00:18:46 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Thread.i (self): Commented out the ACE_Trace call in the - ACE_Thread::self() methods to avoid infinite recursion problems - on Win32. - - * ace/Token.cpp (ACE_Token): Commented out the ACE_Trace call in - the constructor of ACE_Token to avoid infinite recursion - problems on Win32. - - * ace/Log_Msg.cpp (instance): Moved the definition of the static - variable keylock_ into the static instance() method in order to - avoid "order of initialization" problems on Win32. Thanks - to Tim for figuring this out! - -Sun Apr 28 17:07:58 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * netsvcs: Rearranged and renamed the subdirectories so that they - are now called ./netsvcs/{lib,clients,servers}. In addition, - moved the Logger, Naming, and Tokens examples from ./examples - into the ./netsvcs/clients directory in order to make the - relationships more clear. - -Sat Apr 27 14:23:43 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Name_Space.cpp (operator ==): Created a new file - Name_Space.cpp and moved the definitions for - ACE_Name_Binding::operator== and ~ACE_Name_Space in it. Also - modified code to use '_' at the end of name/value/type in - ACE_Name_Binding. - -Sat Apr 27 16:00:03 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/INET_Addr.i (get_host_addr): There was an error where - sprintf(s,"%d:%s" ...) should have been %s:%d. Thanks to - Raj <raj@itd.ssb.com> for pointing this out. - -Mon Apr 22 01:24:45 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Dump_T.h: #included "ace/Dump.h" so that this file will - compile on HP/UX. Thanks to Neil Cohen for reporting this - problem. - - * Released version 4.0.15 for testing. - - * ace/Synch_T: Added the appropriate "const" qualifiers to certain - operators in ACE_Atomic_Op. - -Sun Apr 21 12:54:18 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Fixed a problem that Dieter was having with the Name Server - when toggling between Naming_Contexts. Basically, what I've - done is - - 1. Moved the unmap() call into the ACE_Mem_Map::close() method - (this ensures that the region is correctly unmapped when the - Mem_Map is deleted). - - 2. I've removed the call to this->allocator_->remove () within - ~ACE_Local_Name_Space. This ensures that we don't remove the - backing store file. - - * ace/Mem_Map.cpp: Modified the ACE_Mem_Map::remove method to call - ACE_Mem_Map::close() in order to share code. - - * ace/Mem_Map.cpp: Modified the ACE_Mem_Map::close() method so - that it unmaps the mapped region before closing down the backing - store. This prevents "dangling mapping." - - * ace/Local_Name_Space.cpp (ACE_Local_Name_Space): Initialized all - the pointers to NULL. - - * ace/Synch_T.cpp (ACE_Atomic_Op): Enhanced the Atomic_Op - implementation by adding an assignment operator and disallowing - the copy constructor (forcing objects of ACE_Atomic_Op to be - passed by reference). - - * examples/Naming/Client/Client_Test: Reorganized the code for - Client_Test so that it will run correctly as a Win32 netsvc - (e.g., added the ACE_Svc_Export macro). - -Sun Apr 21 20:23:40 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Naming_Context.cpp (close): Added a new method to - Naming_Context called close() that deletes the instance of - name_space_. - - * ace/Local_Name_Space.cpp (ACE_Local_Name_Space): Added stuff to - the destructor of Local_Name_Space so that it calls remove on - the allocator_ to ensure we unmap the file. Also, we delete the - allocator_. - - * examples/Naming/Client/Client_Test.cpp (set_proc_local): Changed - set_proc_local (), set_node_local() and set_host() so that - before we change name space, we do a close() on - Naming_Context. The close ensures that we unmap the file as well - as delete the instance of the name space. - -Sat Apr 20 12:39:20 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Removed the Name_Options.* files and merged the - ACE_Name_Options class into Naming_Context.*. This simplifies - some order of include problems... - - * ace/Naming_Context.cpp (init): Switched the code so that rather - than always opening with ACE_Naming_Context::PROC_LOCAL, we use - ACE_Name_Options::context(), which can be overridden by using - the new -c command-line option (e.g., -c NODE_LOCAL). Thanks to - Dieter for suggesting this. - - * ace/OS.i: Modified the Win32 implementation of all the - ACE_OS::flock_*lock() methods so that they'd have the same - behavior as the UNIX ones with respect to a length of 0 meaning - "lock the entire length of the file." This works, of course, by - having each method check if len == 0, and if so, calling - GetFileSize() to set the size of the file. - - * ace/Synch.h: Changed the default len value for all the - File_Lock::*acquire* methods to 1 rather than 0 to work around a - problem with Win32. Thanks to Detlef for reporting this. - - * ace/ACE.cpp (ldfind): Added a strdup() of the LD_SEARCH_PATH - returned by getenv() so that we don't overwrite the environment - variable by using strtok(). Thanks very much to Prashant for - figuring this out! - -Thu Apr 18 22:13:43 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * examples/Naming/Client/Client_Test.cpp (list_value_entries): - Added check in list_name_entries and list_value_entries to see - if type actually exists before trying to print it out. - -Wed Apr 17 16:40:42 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.14 for testing. - - * Added Tim Harrison's new instructions for building and using ACE - as a DLL and SLL on Win32. - - * ace/Svc_Conf.h: Due to the new changes to the yacc code, I had - to move the definition of YYSTYPE into the Svc_Conf.h file - rather than have it in the Svc_Conf.y file. This solves a - variety of multiple-inclusion problems... - - * ace: Modified all the yacc token symbols so that they will be - prefixed with ACE_. This avoids namespace pollution problems. - - * Added the ACE_STATIC_SVC* macro support to a number of files so - that the static versions of all the ACE services will be - registered with the ACE Service Repository correctly. Thanks to - Jesper for pointing this out! - - * ace/OS.h: the first occurence of - - typedef thread_t tid_t; - - in the OS.h file should read - - typedef pthread_t tid_t; - - Thanks to Jan Rychter <jwr@icm.edu.pl> for reporting this. - - * ace/Read_Buffer.cpp: Fixed rec_read() so that it will fail - correctly when new fails! - -Wed Apr 17 19:05:42 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * netsvcs/lib/Name_Handler.cpp (type_request): Here is a brief - description of the changes made to ACE_Name_Handler to simplify - the dispatch method and make it more elegant: - - 1) I created a table called op_table_. It contains pointers to - member functions of ACE_Name_Handler. This table can be - indexed using the msg_type. However, I went one step further - to have all the list methods be grouped under two - methods. That is, requests for list_names, list_values, and - list_types are handled by one method called lists() and - similarly, requests for list_name_entries, - list_value_entries, and list_type_entries are handled by - another method called lists_entries(). A MASK is used to have - the op_table_ index to the same method for these requests. - - 2) I also created another table called list_table_. This is - primarily used by lists() to keep track of a couple of things: - + pointers to member functions of Name_Handler that - handle the actual request. - + pointers to member functions of Name_Handler that act - as factories to create the appropriate request to - send back. - + description of the message type. - - A different MASK is used to index into the list_table_ to - invoke the appropriate method or get the appropriate description. - - 3) Within the method lists_entries(), I once again make use of - the pointers to member functions technique. This time, - however, I use pointers to member functions of Naming_Context - which I assign in the switch statement. - -Tue Apr 16 13:03:49 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.13 for testing. - - * ace/INET_Addr.i: moved the get_port_number routine up to the top - of the file so it gets defined before it is used. Linux did not - like it where it was... Thanks to Neil Cohen for reporting - this. - - * ace: Split the Dump.* files into Dump_T.* files. This is - necessary to support the template policies of various C++ - compilers. - - * ace/Malloc_T.cpp (dump): Fixed an erroneous use of -> since - guard_ is a non-pointer... Thanks to Neil Cohen for reporting - this. - - * ace/Log_Record.cpp (print): Finally figured out how to do - extensible ostream logging so that it will seamlessly work with - ACE_Log_Msg. This required one change to ACE_Log_Record, - however. In Log_Record.cpp: - - In ACE_Log_Record::print(char *, int, ostream, size_t len), added - - char *t = this->msg_data_[len - 1]; - - if (t == '\n') - *t = '\0'; - - s << this->msg_data_ << endl; - - This is required because the virtual function overflow() in - streambuf does not get called until endl is called to flush the - buffer. Note that (at least on AIX), '\n' is treated separately - from endl and will not cause the overflow() function to be - called. Thanks to Chris Lahey for this idea. - - * ace/OS: Added a new wrapper for strrchr(). - - * ace/Token_Collection.cpp (renew): Added a cast of - (const char *) to token_name so that the conversion operator - will get called correctly. Thanks to Gonzalo Diethelm - <gonzo@ing.puc.cl> for reporting this. - -Tue Apr 16 13:29:32 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Name_Request_Reply.cpp (decode): Fixed a small bug in encode() - and decode() of ACE_Name_Request. When doing ntohs and htons, we - only ought to do it for the name and value part of data. type - needed to be left alone since it is not a short. - -Mon Apr 15 02:31:00 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * include/makeinclude/platform_hpux_orbix.GNU: Added - David.L.Sames.1@gsfc.nasa.gov (David Sames) config*.h file and - platform_*.GNU file for HP/UX 9.x using Orbix. - - * ace/OS.i: Fixed all uses of pthread_cleanup_{pop,push} so that - they will work correctly if (1) the OS implements the as macros - and (2) if these macros must obey strict nesting rules... - Thanks to Reginald S. Perry <perry@zso.dec.com> for pointing out - how to do this effectively. - - * ace/Thread_Manager.h: Fixed a typo where the typedef - - typedef (ACE_Thread_Manager::*THR_FUNC)(int, int); - - was lacking a return value. Thanks to Reginald S. Perry - <perry@zso.dec.com> for reporting this. - - * netsvcs/bin/main.cpp (main): Fixed the main program so that it - passes the options correctly for the statically linked service - invocations. Thanks to Jesper for reporting this. - - * examples/Naming/Client/Client_Test: Updated the client test - program so that it will work on Window NT, where it's not valid - to select() on non-socket HANDLEs (ugh). Thanks to Jesper for - pointing this out... - - * Released version 4.0.11 for testing. - -Mon Apr 15 00:20:02 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Local_Name_Space.cpp (strstr): Fixed ACE_NS_String::strstr - to function properly. It was assuming that length of the pattern - as well as the string was in units of ACE_USHORT16 when in - reality the length is number of bytes. - - * ace/Local_Name_Space.cpp (value_): Modified ACE_NS_Internal so - that instead of taking an ACE_NS_String for type, it now take a - char*. It therefore keeps type around as a char*. This should - help solve some problems we were encountering with byte ordering - when sending data between NT machines and Sun. - - * netsvcs/lib/Name_Handler.cpp: Cleaned up lists_entries by making - use of pointer to member functions. A single call to the - appropriate list method takes care of everything. - -Sun Apr 14 16:21:32 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/INET_Addr.i (addr_to_string): Swapped the order that the - hostname and port number are printed to make this consistent - with the way that ACE_INET_Addr::string_to_addr works. Thanks - to Ashish Singhai <singhai@delirius.cs.uiuc.edu> for pointing - this out. - - * ace/TLI_Acceptor: Changed the methods to take an ACE_Addr rather - than an ACE_INET_Addr. This allows other address families (such - as DECnet) to be used with the TLI wrappers. Thanks to Ajit - Sagar <asagar@spdmail.spd.dsccc.com> for suggesting this. - - * ace/Local_Name_Space.cpp (list_types): Removed the use of - regular expression matching for the name and value types of the - name server and replaced these with substring matching instead. - This is necessary since we're working with wide characters here, - and it doesn't make any sense to perform regular expressions on - these puppies... - - * ace/Local_Name_Space.cpp: Added a new strstr() method on all the - ACE_NS_String class so that we can compare substrings for wide - character types. - - * ace/SString: Added a new strstr() method on all the - ACE_[WSC]String classes so that we can compare substrings, - even for wide character types! - - * apps/gperf: Incorporated the GNU gperf program from the FSF. - We're going to make some improvements to this for a subsequent - paper. - -Sun Apr 14 15:30:05 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Name_Request_Reply.h: Changed the enum values for the - Constants such as BIND, REBIND, etc. The new values allow us to - do bitwise operations using MASK to be able to dispatch the same - method for all the list operations. For use case of this, please - see Name_Handler::dispatch(). - - * netsvcs/lib/Name_Handler.cpp (dispatch): Completely changed - dispatch() so that now it uses a table of pointer to member - functions to call the appropriate method when a request - arrives. In addition, requests for LIST_NAMES, LIST_VALUES, and - LIST_ENTRIES are now handled by one method called lists() in which - I factored out a lot of common code. Similarly, requests for - LIST_NAME_ENTRIES, LIST_VALUE_ENTRIES, and LIST_TYPE_ENTRIES are - handled by lists_entries(). This has really cleaned up the code. - -Sat Apr 13 15:26:51 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Name_Request_Reply.cpp: Made changes so that all - byte-ordering computations take place in encode and decode - methods of ACE_Name_Request_Reply and ACE_Name_Reply - only. Previously some of these computations were taking place in - Get/Set methods such as name_len() which was highly error prone. - (init): Added new methods called init() to both ACE_Name_Request - and ACE_Name_Reply that initialize length to size of transfer_. This - is needed since the length gets set only once in the constructor - and after that each call to encode() switches the byte ordering - causing problems. - -Sat Apr 13 11:44:16 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.10 for testing. - - * ace: Removed the ACE_HAS_THREAD_T macro from various places. - This was unnecessary given the new scheme for dealing with - threading. - - * ace/config-linux-pthread.h: Fixed a typo that was preventing - compilation from working. Thanks to Jan Rychter - <jwr@icm.edu.pl> for finding this. - -Fri Apr 12 13:17:47 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/Gateway/Gateway: The gateway application appears to - be working again! - - * ace/OS.cpp (thr_create): Based on conversations with Chris - Lahey, modified the pthreads ACE_OS::thr_create implementation - so that it doesn't try to assign the hthread_t thr_handle since - this is meaningless in pthreads... - - * apps/Gateway/Gateway/Gateway.cpp: Fixed a typo that was causing - the system to go into an infinite loop when the config file was - empty! - - * apps/Gateway/Gateway/Gateway.cpp: I was forgetting to set the - line_number to 0 before calling read_entry()... - - * ace/Parse_Node.cpp: Fixed a dumb error that arose because I - forgot that you can't call dlerror() twice and get the same - result (it returns NULL the second time). As usual, RTFM. - - * ace: Removed ACE_HAS_TLI from all the SunOS 4.x config*.h files - and platform_*.GNU files. There are just too many bugs with TLI - on SunOS 4.x to support it by default... - - * examples: Made some minor fixes to make the examples all compile - with GCC. - - * apps/Gateway/Gateway/Gateway: Reimplemented the Gateway - application as to be an ACE network service. This should make - life much easier on platforms with broken C++ templates... - - * apps/Gateway/Gateway: Revised the Config_Parser.* files so that - templates would be split from the non-templates. This avoids - bugs with some C++ compilers... - - * ChangeLog: added the ACE_TEMPLATES_REQUIRE_SPECIALIZATION flag - to the config-linux-pthreads.h file. Thanks to - Jean-Francois.Ripouteau@netsurf.org for reporting this, and also - for archiving the ACE mailing list. - -Thu Apr 11 01:37:25 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.9 for testing. - - * ace: regenerated all the manual pages and html pages. - - * Built ACE successfully on SGI IRIX 5.3 using GNU G++ 2.7.2. - - * ace/Thread_Manager: renamed the descriptor() accessor methods to - hthread_descriptor() and thread_descriptor() to avoid - ambiguities due to the fact that hthread_t and thread_t can now - be the same type. - - * ace/Thread_Manager: revised the hthread_t so that it is always - large enough to hold valid thread ids. - - * ace: Moved the config-osf1.h file to be named config-osf1-3.2.h - in anticipation of OSF/1 4.0... - - * ace: Changed all occurrences of wchar_t to ACE_USHORT16, which - is a more portable way of representing wchar_t's so that we can - pass them across the network... Unfortunately, wchar_t tends to - be different sizes on different machines, so we can't use the - binary form!!! - - * ace: Added many, many small changes to get ACE to compile on - OSF/1 3.2D using DEC C++ 5.3. Thanks to Tom Marrs - <0002104588@mcimail.com> for slogging through all of this stuff! - - * ace/Thread_Manager.h: Fixed a stupid oversight where I forgot to - add a -1 to the trailing argument of spawn*. Thanks to Neil - Cohen for spotting this. - - * ace: Added a new ACE config file for AIX 3.2.5 courtesy of Bob - Olson <olson@mcs.anl.gov>. In addition, I changed the name of the - config-aix.h file to be config-aix-4.1.x.h and called the new - file config-aix-3.2.5.h. - - * apps/Synch-Benchmarks/Benchmark.cpp: Added template - specializations for ACE_TSS and ACE_Atomic_Op. Thanks to Matt - Stevens for pointing out the need for this. - - * ace/CORBA_Handler: Added a number of fixes to get the ACE - CORBA_Handler to compile on Win32 with Orbix 2.0. Thanks to - Rich Ryan <rryan@mseng.kla.com> for these fixes. - - * ace/OS.cpp (thr_create): Fixed a small bug in the pthreads - thr_create() code by dereferencing p_thr before casting it - to hthread_t and assigning it to *thr_handle. - - * ace/OS.i: Backed out the previous changes of pthread_cleanup*. - It turns out that on SunOS 5.5 these macros force a certain - style of programming this is hard to integrate with the existing - implementations of other ACE wrapper methods. Fortunately, none - of this affects existing ACE code since we just use the default - solaris threads API in this case... - - * ace/OS.i: Modified the order of #ifdefs in various ACE_OS::thr_* - methods to take advantage of the pthreads features on Solaris - 2.5. - - * ace: Removed the last few typos that prevented ACE from building - on SunOS 4.x with G++... - - * ace/Thread_Manager: Changed spawn() and spawn_n() so that - they optionally take a group parameter and automatically add - this to an existing thread group. That way we don't need to - spawn the thread(s) and then reassign them after the fact. - The new API automatically assigns the thread(s) to the group - you specify. Thanks to Chris Lahey for this idea. - - * ace: Fully integrated POSIX pthreads into the ACE build for - Solaris 2.5. - - * netsvcs/lib/Server_Logging_Handler.cpp: Rearranged the Server - Logging files so that things will compile and link correctly - using stock GNU G++. - - * ace/Log_Msg.cpp (ACE_Log_Msg): Forgot to initialize the ostream - * to 0. This was causing problems for Win32... - - * ace: *Finally* got the static and dynamic ACE libraries to - compile on SunOS 4.x using stock G++! - - * ace/Synch_T.h: Added a new macro called ACE_SYNCH that will - be ACE_NULL_SYNCH if !ACE_HAS_THREADS and ACE_MT_SYNCH if - ACE_HAS_THREADS. - - * ace/Service_Record.cpp: Changed this to use ACE_SYNCH. This - will fix template problems with G++ on SunOS 4.x. - - * build/SunOS5.5/ace/OS.i (sema_wait): Changed all uses of - ::pthread_cleanup_{push,pop} to pthread_cleanup_{push,pop} since - these are implemented as macros on Solaris.... - -Thu Apr 11 19:43:33 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * examples/Naming/Dump_Restore/Dump_Restore.cpp (init): Modified - Dump_Restore in order to work correctly without having - Name_Options around as a Singleton. - - * examples/Naming/Client/Client_Test.cpp (set_host): Modified - Client_Test in order to work correctly without having - Name_Options around as a Singleton. It simply uses the accessor - provided by Naming_Context to get to Name_Options. - - * ace/Name_Options.cpp: Changed Name_Options so that it is no - longer a Singleton. As a result, now there is an instance of - Name_Options per Naming_Context. Note that for an application to - change Name_Options, it can use the accessor function provided - in Naming_Context. As a consequence of all these changes, we can - now have multiple Naming_Contexts per application. - -Wed Apr 10 20:19:50 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.h: Incorporated a mapping for Solaris 2.5 pthreads so - that it fits in nicely with the earlier ACE pthreads support. - From now on, the pthreads API will be the default threading - scheme for ACE on Solaris 2.5... - - * ace: Added the file name to every *.cpp and *.i file in ACE. - This makes it easier to figure out what's what when looking at - the source code. Thanks to Chris Lahey for suggesting this. - - * ace/CORBA_Handler.cpp (ACE_CORBA_Handler): Added bodies for - the copy constructor and assignment operator of ACE_CORBA_Handler - (which are private) since some compilers generate link errors - for these! Thanks to Rich Ryan <rryan@mseng.kla.com> for - pointing this out. - - * ace/Synch_T.cpp (ts_get): at line 270 (within - ACE_TSS<TYPE>::ts_get (void) const) there was a keycreate() call - that did not have an instance pointer pass in with it. The - symptom has been that if the last active task has been finished - all active tasks being created afterwards won't get the close() - hook invoked. I've fixed this in order to solve a mysterious - bug with ACE_TSS. Thanks to the ever-vigilant Detlef for - reporting this bug and fix. - -Wed Apr 10 01:56:52 1996 Douglas C. Schmidt (schmidt@mambo.cs.wustl.edu) - - * ace: Added the ACE_TEMPLATES_REQUIRE_SPECIALIZATION to - config-sunos5.5-g++.h file. This should allow ACE to build - correctly. Thanks to Adam Miller for pointing this out. - - * ace: Installed SunOS 5.5, so now we can finally test pthreads! - - * ace/OS: Modified the implementation of mutex_t for Win32 so that - it automatically selects the CRITICAL_SECTION or the HANDLE form - of Mutex depending on whether the type argument is USYNC_THREAD - or USYNC_PROCESS, respectively. This now means that all the - existing ACE code that used ACE_Condition<ACE_Mutex> will - continue to work correctly on Win32 and UNIX! - -Tue Apr 9 23:04:30 1996 Douglas C. Schmidt (schmidt@mambo.cs.wustl.edu) - - * ace/Synch: Somehow, the definitions for ACE_Thread_Semaphore and - ACE_Process_Semaphore were MIA. I've added the implementations. - Thanks to Bruce Worden <bruce@betsy.gps.caltech.edu> for - noticing this... - -Tue Apr 9 02:16:02 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Service_Config.cpp: reordered the #includes in this file so - that it works correctly on Win32. Thanks to Rich Ryan - <rryan@mseng.kla.com> for help with this. - - * ace/Auto_Ptr.cpp (remove): added the implementations of the - auto_ptr::remove() and auto_array_ptr::remove() static methods. - Thanks to Chris Lahey for noticing their absence... - - * ace/Auto_Ptr: Added the #pragma implementation ("Auto_Ptr.cpp") - statement if defined ACE_TEMPLATES_REQUIRE_PRAGMA to work on - AIX. Thanks to Chris Lahey for this. - - * ace/Makefile: Moved Auto_Ptr from FILES to TEMPLATE_FILES to - work on AIX. Thanks to Chris Lahey for pointing this out. - - * Modified a bunch of the apps and example Makefiles so that - things will build better using G++. - - * ace/Name_Options.cpp (parse_args): Made the "database" name the - same as the process name by default... - - * ace/Reactor.h: Changed the type of current_ in - ACE_Handler_Repository_Iterator from size_t to ssize_t so that - this can handle negative numbers. Thanks to Mark Zusman - <marklz@rotem.technion.ac.il> for reporting this. - -Mon Apr 8 23:33:15 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * netsvcs/lib/Name_Handler.cpp (recv_request): Fixed a small - bug. In recv_request() ntohl was being called again on length - which was causing problems since the length was already in host - byte order. The ACE Name Server should now be working on NT. - -Mon Apr 8 02:14:30 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Fixed a number of minor problems that caused duplicate - symbols when linking ACE with G++ (no-repo) on SunOS 5.x and - SunOS 4.x. Thanks to Andy Gokhale for help with this. - - * ace: Added Jan Rychter <jwr@icm.edu.pl> very nice contribution - of pthreads and DCE threads to ACE. This should make life - easier for Linux users and users of other pthreads packages. - - * ace/Service_Config.cpp (process_directives): Changed the code to - use an auto_ptr to make sure that we always release the - ace_obstack memory, regardless of how we exit. - - * ace/OS.i (strerror): Changed sys_errlist to _sys_errlist to work - around bugs with SunOS 4.x. This will undoubted break some - other twisted UNIX system. - - * ace/Local_Tokens.cpp (acquire): Added a return 0 at the very - end... Thanks to Chris Lahey for reporting this (yet - again... ;-)). - - * ace/Parse_Node: Made a bunch of small changes to deal with the - fact that there's no dlerror() equivalent on NT... - - * ace/Task.h: The static function instance() should return - ACE_Task_Exit<ACE_SYNCH_1>* (or <ACE_SYNCH_2>), not - ACE_Task_Exit *. Thanks to Chris Lahey for spotting this. - - * ace/Thread_Manager.cpp: added an argument to the exit() method - that allows applications to exit without calling thr_exit. This - would allow the method to be called from within a pthread - cancellation cleanup routine, without calling thr_exit a 2nd - time. Thanks to Chris Lahey for suggesting this. - - * ace/Log_Record.cpp (operator <<): Changed the verbose option so - that it is an attribute, this will allow the ostream to print - verbose information if necessary. Thanks to Chris Lahey for - suggesting this change. - - * ace/config-win32-msvc*.h: Added the - ACE_LACKS_STATIC_DATA_MEMBER_TEMPLATES flag since it appears - that this causes problem with some versions of MSVC++ 4.0... - - * Released version 4.0.6 for testing. - - * netsvcs/lib/Server_Logging_Handler.h: #included the - Svc_Handler.h file, that absence of which was causing problems - for HP/UX. Thanks to Richard Orr - <rorr@costello.den.csci.csc.com> for reporting this. - - * Made a few minor changes to the source to make sure that it - compiles correctly on SunOS 5.x with G++. - - * ace/Thread_Manager.h: Added the insert() method for the non-MT - version of Thread_Manager. Thanks to Alexandre Karev - <akg@na47sun05.cern.ch> for reporting this. - - * ace/Task: Renamed the static double-check lock_ to - ace_task_lock_ to avoid a name conflict with the existing - this->lock_ instance in each class. Thanks to Prashant for - tracking this down... - -Sun Apr 7 14:40:05 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp: - Rolled back a change that replaced #defines with typedefs. It - turned out the #defines were there for a reason... Thanks Neil - B. Cohen <nbc@metsci.com> for pointing this out... - - * ace/OS.h: Added a new check to deal with the fact that many - versions of Pthreads don't support tid_t (which seems to be an - AIXism...). - -Thu Apr 4 01:19:19 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Officially released version 4.0.5... - - * ace/OS.h (ACE_TSS_TYPE): Somehow the ACE_TSS_TYPE macros ended - up *before* the inclusion of Time_Value.h, which meant that - these macros weren't being expanded properly. This may help - explain odd behavior with ACE TSS. - - * ace/Thread_Manager.cpp (insert): Added a new method that allows - us to insert a thread into an ACE_Thread_Control after it's been - constructed. - - * ace/Message_Block: Fixed a typo in the init() method. Thanks to - Ross Dargahi <rossd@krinfo.com> for noticing this. - - * ChangeLog: Finally got all of ACE built on SunOS 5.x and SunOS - 4.x using only the stock GNU GCC compiler (i.e., no template - repository...). This should make it easier to port to other - versions of G++. - - * ace/Task: Modified the ACE_Task and ACE_Task_Exit implemenation - so that it only uses 1 TSS key per ACE_Task template - instantation, rather than 1 TSS key per ACE_Task instance. This - works around horrible limitations with Win32... - - * ace/Thread_Manager: Added new methods to set and get the - Thread_Manager used in a Thread_Control. - - * ace/Pipe.cpp (open): Fixed a bug in where ACE_Pipe::open did not - set this->handles_, thus a garbage handle gets registered. - Inserted the following two lines at line 53 of Pipe.cpp: - - this->handles_[0] = reader.get_handle (); - this->handles_[1] = writer.get_handle (); - - Thanks to Kirk Sinnard <kirk.sinnard@lawson.com> for this fix. - - * ace/OS.h: Added a couple of fixes for the SCO port. Thanks - again to Matt Newhook <matthew@neweast.ca> - - * ace/OS.cpp: Integrated Detlef's clever scheme for freeing up - thread-specific storage correctly on Win32... - - * ace/Task.cpp (ACE_Task): Made sure to initialize the - next_-pointer of ACE_TASK and Message_Queue point to NULL. - This fixes a problem on NT. Thanks to Karlheinz for - noticing this... - - * include/makeinclude/rules.lib.GNU (VLIB): Fixed up the ACE - makefiles so that we can now build on SunOS 4.x correctly - without using the template repositories... - - * ace/Service_Config.cpp: Added a bunch of template - specializations so that GNU G++ can be used to compile ACE on - SunOS 4.x *without* requiring the template repository hacks... - Thanks to Mark Zusman for helping with this. - -Wed Apr 3 00:55:12 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * examples/Reactor/Misc/test_reactors.cpp: Added a new torture - test of the ACE_Reactor and ACE_Task. Thanks to Detlef for - contributing this... - - * netsvcs/bin/Makefile: Removed a stray -lACE_svcs from the - Makefile. Thanks to Matt Stevens for reporting this. - - * ace/Synch.cpp: Fixed two mistakes related to keeping INLINE on - the get_thread_id() and get_nesting_level() when I moved them - into the *.cpp file... Thanks to Matt Stevens for finding this. - - * ace/Reactor.cpp (owner): modified owner() so that it returns - the original owner when setting a new owner. This makes it - possible to write code like this: - - thread_t t; - - reactor->owner (ACE_Thread::self (), &t); - reactor->handle_events (); - reactor->owner (t); - - * ace/SOCK_Connector.cpp (connect): Added an additional check for - errno == EWOULDBLOCK for non-blocking connects due to screwy - semantics of Win32 non-blocking sockets... - - * netsvcs/lib/Client_Logging_Handler: Fixed a very obscure bug - that arose due to the way that UNIX select() interacts with - SVR4 MSG_BAND data. It turns out that you must use the - ACE_Event_Handler::EXCEPT_MASK to get this to work properly - (gag). This stuff is much easier with SVR4 poll(). - -Tue Apr 2 13:57:05 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.i: Fixed an error compiling the new Log_Msg.cpp because - when it inlined OS.i, there were references to - ACE_OS::thread_mutex_*() before the functions were declared - inline. The references were assumed to be external, and then - when the linkage was actually declared as inline, the compiler - choked. To fix this, in OS.i, all the thread_mutex_* calls - where moved above the first reference, which was in - ACE_OS::cond_broadcast(). Also moved the mutex*() calls since - they are referenced by the thread_mutex calls. So the order is - mutex*(), then thread_mutex*(), and then cond*(). Thanks to - Chris Lahey for reporting this. - - * netsvcs/lib/Client_Logging_Handler.cpp: Added missing return - values in some of the methods. Thanks to Tim Harrison for - spotting this... - - * ace/Map_Manager.cpp (shared_unbind): It was possible that INT_ID - could be assigned a value from a previously unbound map entry. - The shared_unbind matches the ext_id, but does not see if the - entry had previously been unbound. This causes a problem if the - INT_ID type is a pointer type, and the user of the map deletes - objects as a result of the unbind returning a 0. The correct - solution is to include a test for is_free in the shared_unbind - before checking the equality of the ext_id. Thanks to Phil - Mesnier <phil@envision.com> for reporting this. - - * ace/Reactor.cpp (next): Fixed a bug that prevented the - iterator's next() method from detecting the end of the - iteration. Thanks to Mark Zusman <marklz@rotem.technion.ac.il> - for reporting this. - - * ace/Reactor.cpp (advance): Fixed a bug that prevented the - iterator from advancing. Thanks to Mark Zusman - <marklz@rotem.technion.ac.il> for reporting this. - - * ace/Log_Msg.cpp (open): Added a check for logger_key being NULL, - in which case we log to STDERR rather than segfault... - - * netsvcs/lib/Server_Logging_Handler.h: Fixed a typo in - the declaration of - - ACE_SVC_FACTORY_DECLARE (ACE_Server_Logging_Acceptor) - - Thanks to Neil Cohen for finding this. - -Mon Apr 1 00:17:21 1996 Douglas C. Schmidt (schmidt@mambo.cs.wustl.edu) - - * ace/Time_Value.i: Fixed two stupid bugs in the Time_Value - relational operators. Thanks to Mathew Newhook - <matthew@thor.udc.neweast.ca> for pointing this out. - - * ace/OS.h: Added an extern "C" block around the netdb, net/if.h, - netinet/in.h, arpa/inet.h to work around problems with SCO. - Thanks to Mathew Newhook <matthew@thor.udc.neweast.ca> for this. - - * ace/Reactor: Merged the ACE_Pipe into the Reactor - implementation. This cleans up some nasty OS-specific code in a - clean way. - - * ace/CORBA_Handler.cpp (ACE_MT_CORBA_Handler): Fixed some typos - that arose during the transition to the ACE_Pipe. - - * ace/Pipe: Added a new open() method that doesn't return the - handles, it just stashes them away for safe keeping. This is - useful for places like the Reactor. - - * ace/Local_Name_Space.h: Added ACE_Export to the front of - ACE_NS_String. Thanks to Detlef for suggesting this. - - * From now on, I'll be numbering each new release of ACE with a - different minor number. However, the latest version of ACE will - also always be available at - - http://www.cs.wustl.edu/~schmidt/ACE.tar.gz - - This is useful if you just want to get the latest one without - having to bother with keeping track of minor numbers. For - instance, that way you can still keep that reference in my - bookmark list and you don't have to remodify it with every - release. Thanks to the ever-vigilant Chris Lahey for suggesting - this. - - * ace: added new a ACE project file (ace.mdp) and Makefile - (ace.mak) to create ACE as a DLL on Win32. This should greatly - simplify the Win32 build process... - - * INSTALL: Added new INSTALL file explaining how to build for - Win32. - - * ace/Thread_Manager.cpp: Fixed a horrible bug with Win32. On - reasonable systems ACE_Thread::exit() should not return. - However, due to horrible semantics with Win32 thread-specific - storage this call can return (don't ask...). Therefore, we need - to reacquire the mutex so that we don't get burned when the - Guard automatically releases it when this method returns. Thanks - to Tim for helping me figure this out. - - * ace: Fixed some problems with errno in Remote_Tokens and - Local_Tokens. - - * ace/Reactor.cpp: Fixed an annoying preponderance of useless - ACE_MT_SAFE #ifdefs in the Reactor implementation. Thanks to - Gerolf Wendland <wendland@hpp015.mch2.scn.de> for pointing this - out! - -Sun Mar 31 13:09:27 1996 Douglas C. Schmidt (schmidt@mambo.cs.wustl.edu) - - * ace/OS: Changed the implementation of cond_t and rwlock_t for - Win32 to use thread_mutex_t (i.e., CRITICAL_SECTIONS) rather - than mutex_t (i.e., Win32 Mutexes). This should improve - performance without sacrificing generality (of which there is - none at the moment since we don't have process-wide condition - variables or readers/writer locks on Win32 anyway.. - - * ace/Thread_Manager.cpp (remove_thr): Fixed bugs in the - ACE_Thread_Manager class. The wait() member grabbed the - Thread_Mutex lock_, then (if the current_count is not zero) - grabs the Condition lock zero_cond_. Doing so, however - implicitly released lock_, which meant that another thread could - get into wait(), and wait on zero_cond_. zero_cond_ was only - signaled from ACE_Thread_Manager::remove_thr() when the - current_count_ is zero, but it signaled with - ACE_Condition_Thread_Mutex::signal(), which only releases one - thread that is waiting on the Mutex. Thus, any other threads - waiting on zero_cond_ would never be resumed. The fix was to - use ACE_Condition_Thread_Mutex::broadcast() rather than - ACE_Condition_Thread_Mutex::signal() in - ACE_Thread_Manager::remove_thr(). This fix is only reliable - since remove_thr() is called only when ACE_Thread_Manager::lock_ - is held by the calling thread. Thank to Bruce Worden - <bruce@seismo.gps.caltech.edu> for reporting problem and - suggesting this fix. - - * ace/Token: Modified this class so that it only works with - ACE_Thread_Mutex (which is more precise than what was going on - before...). - - * ace/Synch.h: Modified ACE_RW_Process_Mutex so that on Win32 it - uses ACE_Process_Mutex until we've got a working - RW_Process_Mutex for Win32... - - * ace/Synch: Removed the ACE_Process_Barrier until we get a - working implementation... - - * ace/Synch: Changed the ACE_Barrier so that it only tries to work - within a single process. - - * ace: Changed all uses of ACE_Condition_Mutex to - ACE_Condition_Thread_Mutex to reflect what's really going on - here... - - * Changed all uses of ACE_Mutex to ACE_Thread_Mutex throughout - ACE. This is *much* more meaningful and makes it possible to do - some great optimizations on Win32! - - * ace: Changed all uses of ACE_Mutex_Guard to - ACE_Thread_Mutex_Guard. This is a more accurate name for how - this is used in ACE. - - * netsvcs/lib/Client_Logging_Server: Reengineered the ACE - Client_Logging service so that fits into the ACE network service - format. This version is particularly interesting since it - illustrates a "Connector-driven" service. In contrast, all the - other ACE network services are "Acceptor-driven" services. - - * netsvcs: Merged the implementation of all the ACE network - services into a single ./netsvcs/lib directory. Each of these - is now a fully dynamically linkable service. Created a single - main.cpp program in the ./netsvcs/bin directory. This main - illustrates how to dynamically link an or all of the ACE network - services to form complete applications. Thanks to Prashant for - help with this. - - * ace/OS.cpp: Changed readv() and writev() so that they will once - again compile for Win32. Note, however, that if you try to - readv() and writev() on the same descriptor you will lose since - they are not atomic! However, this stuff is stuff useful if - you're *not* reading/writing to a common descriptor... - - * ace/Synch_T.cpp: Removed the ACE_Null_Condition<> template. - This didn't really make any sense... - - * ace/OS: Changed the test of lock_.get_nesting_level() in - ACE_TSS_Cleanup::exit () to account for the fact that a - ACE_Recursive_Thread_Mutex now starts out with a nesting level - of 1 when it is first acquired. - - * ace/Synch_T: Removed the implementation of ACE_Recursive_Lock. - It just doesn't generalize correctly to other types of - synchronization mechanisms... - - * ace/Synch: Reimplemented ACE_Recursive_Thread_Mutex using Dave - Butenhof's <butenhof@zko.dec.com> strategy. This fixes some - latent race conditions in the original implementation. - - * ace: Changed the name of ACE_Recursive_Mutex to - ACE_Recursive_Thread_Mutex since the current implementation - really only works for Thread_Mutexes or Thread_RW_Mutexes... - - * ace: Removed the "Assert.h" file and moved its functionality - into Log_Msg.h. This is more consistent with the rest of the - error reporting and logging in ACE and also avoids some nasty - circular include problems. - - * ace/Local_Tokens.cpp: Changed the use of ACE_RETURN so that it - passes in errno. - - * ace/Log_Msg: Changed the arguments to the ACE_RETURN macro so - that errno can be returned explicitly. - -Sun Mar 31 15:52:58 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Local_Name_Space.cpp (create_manager): Added three new - methods -- list_name_entries, list_name_values, and - list_name_types. They work similar to list_names, list_values, - and list_types (respectively) except they return the entire - tuple associated with a name binding. - -Sat Mar 30 16:46:32 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/SPIPE_Stream.i (send_handle): There was a typo -- the - parameter shouldn't be "const ACE_HANDLE handle", it should - just be ACE_HANDLE handle. - -Sat Mar 30 16:09:25 1996 Douglas C. Schmidt (schmidt@mambo.cs.wustl.edu) - - * INSTALL: Added new Win32 installation instructions to build - ACE as a DLL. - -Sat Mar 30 14:42:02 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Carefully tested ACE on SGI and SunOS 5.x using G++ and CC. - Everything seems to work now... Released version 4.0.2. - - * ace/Acceptor.cpp (ACE_Strategy_Acceptor): Added default - initializations of NULL for service_name_ and - service_description_ in the ACE_Strategy_Acceptor's default - constructor. - - * ace: Fixed a slew of warnings for HP/UX. Thanks to John Morey - for reporting these. - - * ace/FILE.h (ACE_FILE_Info): Changed the type of field size_ from - size_t to off_t to avoid warnings from C++ compilers... - - * ace/OS.cpp (ftruncate): Added a new function for platforms like - SCO that lack ftruncate(). Thanks to Matthew Newhook - <matthew@neweast.ca> for contributing this. - -Sat Mar 30 12:41:16 1996 Douglas C. Schmidt <schmidt@pride.cs.wustl.edu> - - * ace: Removed the ACE_svcs library for the time being and merged - everything back into libACE. There were two reasons for this - change: - - 1. There is a subtle dependency between the ACE_Reactor and the - ACE_Local_Tokens* stuff when deadlock detection is enabled. - This was causing problems. - - 2. This was driving GNU G++ nuts because of the need to - do the "prelink." - - Sooo, for the time being, there's just one ACE library. If - anyone wants to take the time to split everything up so that it - works for all different platforms and send me the fixes I'll be - glad to include this in ACE. - - * ace/Thread.i: Made the ACE_Thread::thr_self() methods call - down to the ACE_OS::thr_self() methods for the case where - the platform doesn't support threads. This means that we - only have to set the default thread id in one place... - -Sat Mar 30 11:53:31 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * bin/class2info.awk: Modified the handleClass() AWK function so - that it can correctly deal with the new ACE_Export and - ACE_Svc_Export tags needed to build ACE DLLs... Here's the - trick: - - sub( "^[\t ]*class[\t ]+(ACE_[.]*Export[\t ]+)?", "", $0 ) - - completely intuitive, eh? ;-) - - * apps/Gateway: Reimplemented the Gateway prototype so that it - uses the new Reactor cancel_wakeup() and schedule_wakeup() - methods instead of mask_ops(). - - * ace/Reactor: Added new high-level <Event_Handler> "scheduling" - operations called schedule_wakeup() and cancel_wakeup(). These - methods utilize the lower-level Reactor mask_ops() methods to - schedule and cancel Event_Handlers for subsequent dispatching by - the Reactor. I added these new interfaces because they are more - intuitive than calling mask_ops(), which is a non-descriptive - name unless you understand the Reactor implementation... - - * ace/config-irix5.*.h: It turns out that on IRIX 5.x the - bi-directional SVR4 pipe semantics are *disabled* by default. - Therefore, I've changed the config-irix4.*.h files to comment - out ACE_HAS_STREAM_PIPES. - -Fri Mar 29 08:25:33 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/ACE.cpp (ldfind): Changed the character given to strtok() to - account for the differences in UNIX and Win32 described in the - follow bullet. - - * ace/OS.h: UNIX and Win32 use different characters to separate - pathnames in their runtime LD search path (':' and ';' - respectively). Therefore, I've added new macros to ACE OS to - account for this stuff portably. - - * ace/OS.i: Changed the behavior of the ACE_OS::thr_self() methods - so that they always return 1 if ACE_HAS_THREADS is *not* - enabled. This makes application code work correctly across - threaded and non-threaded platforms. - - * ace/OS.i: Changed the return value of the Win32 arm of the - ACE_OS::dlopen() and ACE_OS::dlsym() functions so that they are - now identical to the way that UNIX behaves. - - * ace/Svc_Conf.y: added a #define for ACE_BUILD_DLL to make Win32 - happy... - - * ace/Synch.i: Fixed a number of bugs in the ACE_Mutex and - ACE_Thread_Mutex tryacquire_read() and tryacquire_write() - methods. I was calling mutex_lock() rather than - mutex_trylock()! Thanks to Prashant for finding this. - - * ace/OS.cpp (exit): Fixed a bug caused by the fact that the test - for the nesting level of the recursive mutex should have been - for > 0 rather than > 1. Thanks to Kirk Sinnard - <1764@mn.lawson.lawson.com> for tracking this down! - - * ace/Log_Msg: Enhanced ACE_Log_Msg so that it automatically - caches the process id. This makes it more robust even if users - don't call open()! - - * examples/Connection/non_blocking/CPP-connector.cpp Fixed a bunch - of typos that caused templates to fail on HP/UX. Thanks to Neil - Cohen for spotting this. - - * ace/Shared_Memory_SV: Change all uses of "int id" to "key_t id" - to reflect the new use of key_t in the Memory_Pool. - - * ace/Memory_Pool.cpp (ACE_MMAP_Memory_Pool): Fixed a potential - but in the construction of an MMAP memory pool. Because NT uses - strings rather than integers to name its semaphores we were - passing in junk to the NT Process_Mutex initializer. Arrgh! I - fixed this problem by typedef'ing key_t to be char * on Win32 - and then updating the ACE_DEFAULT_SEM_KEY to be - "C:\\temp\ace.sem" rather than 1234.... Also added a new macro - called ACE_INVALID_SEM_KEY, which is NULL on NT and -1 on UNIX. - - * ace/Log_Msg.cpp (instance): Fixed a typo for HP/UX and - other non-threaded platforms! - - * ace/Synch_T.cpp (ACE_TSS_Guard): Added another small fix - to ACE_TSS_Guard to make sure we free up the key when we - go away. - -Thu Mar 28 15:28:44 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.h: changed the names of macros ACE_DYNAMIC_SVC* to new - names that reflect their new, more general nature now that we've - got the ACE_Static_Svcs stuff... - - * ace/Service_Config.cpp (load_defaults): Added a very nice - mechanism that generalizes the configuration of statically - linked services. This makes it possible to insert statically - linked services into a program without changing any of the - existing ACE_Service_Config code. These static services can - then be enabled via the svc.conf file using the "static" - directive. Thanks to Matthew Newhook <matthew@neweast.ca> for - suggesting this and for doing the bulk of the implementation. - - * ace: Commented out the ACE_TRACE calls in ACE_Unbounded_Set, - ACE_OS, and all the ACE synchronization wrappers to work around - some horrible dependencies with Win32 and thread-specific - storage... The moral here is that you have to be careful what - you trace because circualar dependencies abound... My new - policy is that low-level routines are not automatically traced - because they can cause infinite recursion. - - * ace/Synch_T.cpp: Fixed a nasty bug with ACE_TSS_Guard. This was - causing programs that uses ACE_TSS_Guard to segfault... Thanks - to Kirk Sinnard <kirk.sinnard@lawson.com> for reporting this. - - * ace/Synch: Added "lock()" methods to all the ACE synchronization - wrappers to return the underlying C level object... This is - necessary at some points in ACE. - - * ace/Synch: Fixed a horrible bug in ACE_Recursive_Mutex and - ACE_Recursive_Lock that was causing instant deadlock because the - non-recursive Solaris/Pthread mutex was being acquired too - eagerly... - -Thu Mar 28 12:14:57 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Map_Manager.cpp (rebind): Added a new method called resize() - which increases the size of the map. Both open() and - shared_bind() make use of this method to dynamically increase - the size of the map. - - * ace/Local_Name_Space.cpp (shared_bind): Modified shared_bind() - in accordance to the changes to Map_Manager. shared_bind() no - longer has to check if the map runs out of room since - Map_Manager dynamically grows the map. - - * ace/Map_Manager.cpp (shared_bind): Changed shared_bind() so that - when the map reaches max_size_, we grow the map by DEFAULT_SIZE - by making a call to open(). - -Wed Mar 27 20:00:47 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Local_Name_Space.cpp (shared_bind): Fixed a bug which was - allocating memory for a name binding which would fail on a bind - since there already existed a binding. This was causing the - mapped-file to grow even when binds would fail. - -Tue Mar 26 13:49:24 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/INET_Addr.i (addr_to_string): Moved the order of - get_host_addr() so that it comes before addr_to_string(). - Thanks to Neil Cohen for finding this. - - * ace/Synch: Added a new implementation of ACE_Thread_Mutex that - takes advantage of the new ACE_OS::thread_mutex_* mechanisms. - - * ace/OS: Added a new set of ACE_OS::thread_mutex_* mechanisms - that map efficiently to either Win32 CRITICAL_SECTIONs or UNIX - mutex_t's with type set to USYNC_THREAD. This allows ACE to - take advantage of the lightweight Win32 synchronization - mechanisms. When Windows NT 4.0 comes out, we'll at last have a - perfect mapping since WinNT 4.0 supports - TryEnterCriticalSection! - -Tue Mar 26 17:35:31 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Map_Manager.cpp: Added two new methods -- total_size() and - current_size() which return the max_size and current_size of the - map respectively. - -Mon Mar 25 20:22:25 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Service_Config.cpp (initialize): Updated the use of ACE_ARGV - to use the new method names. - - * ace/ARGV.cpp (ACE_ARGV): Changed the name of the two main - methods of ACE_ARGC from count() and operator&() to argc() and - argv(). This seems much more consistent with UNIX and C/C++ - naming conventions. - - * ace/ARGV.cpp (ACE_ARGV): Added environment variable substitution - to the ACE_ARGV class using the new ACE::strenvdup() method. - This is transparently available to the ACE Service Configurator - now, which enables the svc.conf file to include things like - this: - - dynamic Name_Service Service_Object * - name_svc.so:make_Name_Service() "-p $PORT -h $HOST" - - * ace/ACE: Added a new function called strenvdup() that returns a - dynamically allocated duplicate of its <str> argument, - substituting the environment variable if str[0] == '$'. - - * ace/Naming_Context: Modified this class so that it now inherits - from ACE_Service_Config. This enables application programmers - to dynamically link instances of ACE_Naming_Context into their - applications via the svc.conf file. - - * ace/OS.i (access): Added a new wrapper for the access() method. - - * ace/Local_Name_Space.cpp: Fixed an error in each list_xxx - methods. If there's an error in the for-loop we must still call - ACE_OS::free() to release resources. Thanks to the - ever-vigilant Karlheinz Dorn for spotting this. - - * ace/Strategies: added virtual methods with name dump() to - ACE_Scheduling_Strategy, ACE_Schedule_All_Reactive_Strategy, and - ACE_Schedule_All_Threaded_Strategy. These methods are - referenced in ACE_Strategy_Acceptor::dump() method - (Acceptor.cpp). Thanks to Alexandre Karev for reporting this. - - * include/makeinclude: Added a number of changes to allow ACE to - build shared libraries correctly on AIX. Thanks to Chris Lahey - for these fixes. - - * ace/Makefile: added tempinc to the list of directories to delete - for "clean". Also, between the call to the two sub make files, - added a $(RM) -rf tempinc. Since we make both libs from the - same directory, we need to delete the tempinc directory to be - sure we don't get the templates generated for libACE included in - libACE_svcs. - - * ace/OS.i: Improved the mapping between ACE Win32 GetLastError() - values and POSIX-like errnos. This is now centralized in the - ACE_FAIL_RETURN macro. - - * examples/Threads/test_thread_specific.cpp: Added many new tests - to exercise the ACE thread-specific storage mechanisms on Win32 - and UNIX. - -Mon Mar 25 4:00:01 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Name_Options.cpp (parse_args): Added a new data variable - called database_ that keeps the name of the name server - database. Also added accessor methods for this. - - * ace/Local_Name_Space.cpp (create_manager): Changed - create_manager() to use ACE_Name_Options::instance ()->database - () instead of ACE_Name_Options::instance ()->process_name(). - - * ace/ACE.cpp (ldopen): Added a new method called ldopen that - finds a file either using absolute path or using - LD_LIBRARY_PATH. If the file is found, it opens the file and - returns a pointer to the file. - - * ace/Parse_Node.cpp: used the new ACE::ldfind() method to locate - the shared object file. This makes it possible to put - "relative" names into svc.conf files and then allow ACE to - locate the appropriate shared object DLL. - - * ace/ACE: added new methods called ldopen() and ldfind() that - find the file <filename> either using absolute path or using - LD_LIBRARY_PATH. If found, ldopen() opens the file and returns - a pointer to the file. - -Sun Mar 24 10:41:12 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Compiled ACE successfully on Windows '95. - - * ace/OS: Totally redid the ACE thread-specific storage cleanup - mechanism in OS.cpp to avoid bugs with the previous - implementation. - - * ace/Synch_T: Modified ACE_TSS_Guard so that it will call - ACE_OS::thr_keyfree () when it's finished. This should help to - eliminate the unbounded use of thread-specific storage slots - within a thread. - - * ace/Thread: added a new method keyfree() that calls down to the - ACE_OS::thr_keyfree (). - - * ace/Thread_Manager.cpp: Modified the semantics of - ACE_Thread_Manager::exit () so that it "always" calls - ACE_Thread::exit () even if the user hasn't registered this - thread with the thread manager. This avoids some subtle - problems that arise typically when I forget to put an - ACE_Thread_Control around the main() function. - - * examples/Threads/test_thread_specific.cpp: Added new tests to - ensure that the Win32 TSS cleanup logic is working correctly! - - * ace/Log_Msg: Moved the definition of the ACE_FIFO_Send_Msg queue - from the Log_Msg.h file to the Log_Msg.cpp file. The MSVC++ - compiler was having problems with this when building a DLL. - Besides, this needs to be replaced with Sockets for Win32 - anyway... - - * ace/OS.cpp: Put a safe guard in the readv() and writev() - emulations so that they return ACE_NOTSUP_RETURN if - ACE_HAS_THREADS is enabled. This is necessary because the - readv() and writev() emulations are *not* atomic if multiple - threads are used. If someone can provide an atomic - implementation I'll enhance the code to remove the existing - restrictions. - - * ace/OS: Created a new macro called ACE_SYSCALL_FAILED, which is - mapped to 0xFFFFFFFF on Win32 and -1 on UNIX. - - * ace/Synch and Synch_T: cleaned up the implementation of the - Recursive_Lock and Recursive_Mutex to use the ACE_Guard classes. - This simplifies the code. - -Sat Mar 23 16:53:14 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace: Updated all ACE classes to use the new ACE_Export macro. - This will enable them to transparently be used to create a Win32 - DLL. Also added ACE_BUILD_DLL to all the *.cpp files. - - * tests/CPP-inserver.cpp (main): Modified CPP-inclient.cpp and - CPP-inserver.cpp to use non-blocking I/O. In particular, - CPP-inserver times out on select and then checks to see if any - connections have arrived. Both applications are also working on - NT. - -Sat Mar 23 15:02:47 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Local_Tokens.cpp (proxy_): Modified the print statement for - local tokens to account for the fact that thread ids can be - unsigned on some platforms. - - * ace/Log_Msg.cpp (log): Modified the output format of the %t - directive to ACE_Log_Msg::log() so that it prints values in - unsigned form rather than signed form. This fixes a bug with - Win32 on Windows '95. - - * ace/ACE: Added two new methods ACE::read_n() and ACE::write_n(). - These are now necessary since Win32 distinguishes between - operations on SOCKETs and operations on other forms of HANDLEs. - - * ace/ACE: Changed all uses of ACE::set_fl() and ACE::clr_fl() to - ACE::set_flags() and ACE::clr_flags(). - - * ace/ACE: Changed the name of ACE function handle_timed_connect() - to handle_timed_open() since this is reall what it does... - -Fri Mar 22 00:11:19 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Stack: Added a "Node of last resort" to the - ACE_Unbounded_Stack. This ensures we are graceful in the face - of memory failures. - - * ace/OS.i (sleep): Fixed a bug with the Win32 ACE_OS::sleep - mapping. This should have had an "ACE_OSCALL_RETURN" in it... - - * ace/ACE.h: Had forgotten to put "static" in front of "basename". - Thanks to Neil Cohen for reporting this... - - * ace/Name_Options.cpp (process_name): Changed char * to const - char * to avoid compile error. Thanks to Neil Cohen for this... - - * ace/IPC_SAP: Implemented the enable()/disable() methods to work - with non-blocking I/O for SOCKETs on Windows NT. - - * ace/OS.i: Modified ioctl() to support the ioctlsocket() call on - Windows NT. - - * ace/Log_Msg.cpp (log): Fixed a bug that was caused by not - NUL-terminating the logging string properly when a %a is given. - Thanks to Tim Harrison for finding this. - - * ace/OS: Added a new overloaded "ACE_OS::sleep" method that takes - an ACE_Time_Value rather than a u_int. This is much more useful - for fine-grained timers than the horrible UNIX sleep() call. - - * ace/OS.h: #included "sys\timeb.h" in the Win32 version of ACE. - -Thu Mar 21 22:18:50 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps: Fixed all incorrect usages of ACE_HANDLE = -1 to use - ACE_HANDLE = ACE_INVALID_HANDLE in order to work with Win32... - - * ace/OS.i (gettimeofday): Replaced the existing implementation of - gettimeofday with a new version that is shorter, more efficient, - and most importantly, correct... Thanks to Todd Montgomery. and - Mike Flinn for this stuff. - - * ace/ACE: added a new method called basename() that returns the - filename portion of a pathname. - -Thu Mar 21 21:51:48 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/OS.h (ACE_DEFAULT_GLOBALNAME): Added some new #defines for - NT: ACE_DEFAULT_NAMESPACE_DIR, ACE_DEFAULT_LOCALNAME, and - ACE_DEFAULT_GLOBALNAME. - - * ace/Local_Name_Space.cpp (ACE_Local_Name_Space): Fixed a subtle - bug. Instead of doing a new char [xxx], I was doing a new char - (xxx). Also, added some #if defined (ACE_WIN32) to support - special cases for NT (for example determining the context file - name). - -Wed Mar 20 02:03:39 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Log_Msg.cpp (log): If we're writing to stdout or to an - iostream make sure the lock is help to avoid race conditions and - scrambled output. - -Tue Mar 19 00:12:25 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Thread_Manager.h: Added new default values to spawn() and - spawn_n(). - - * ace/OS.i (sigaction): Added support for signals to the ACE NT - mapping. - - * ace/ACE: Added 4 new methods to class ACE: send(), send(), - recv(), recv(). These calls mask some differences between UNIX - and Win32 IPC mechanisms. Then, reimplemented the Reactor's - notification mechanism to use this. - - * ace/OS.i (ACE_OSCALL_RETURN): fixed zillions of warnings on - HP/UX by making a small change to line 151 of the OS.i file. - Thanks to Neil Cohen for reporting this. - - * ace/Reactor.cpp: Rewrote the Reactor::notify() mechanism to - avoid using readv() and writev(). These work fine on UNIX, but - don't work correctly on Windows NT due to race conditions. - Basically, we need to reimplement this stuff on Win32 to avoid - the problem. - - * ace/OS.h: Added SIGQUIT, SIG_BLOCK, SIG_UNBLOCK, and SIG_SETMASK - definitions to NT. - - * ace/Time_Value: added a new set() method to be consistent with - the ACE_Time_Value (long, long) constructor. - - * ace/Service_Config.cpp (open): Fixed a bug where the - ACE_Service_Repository and ACE_Reactor weren't being initialized - correctly if the ACE_Service_Config::ACE_Service_Config (const - char *) method was called. - - * ace/Service_Config.cpp: Changed the constructor for - Service_Config so that it doesn't barf if the svc.conf file - isn't found. - -Mon Mar 18 00:34:45 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Reactor.h: Hid the inclusion of the Local_Tokens.h file in - the Reactor so that by default there will be no dependency - between libACE and libACE_svcs. This should prevent compilation - problems on some platforms. - - * bin: Included the html-windex shell script from Vincent Pommier - <pommier@volnay.stortek.com>. - - * man: Included a shell script to automatically generate an - acewindex.html file. This file is useful just after running - man2html. Thanks to Vincent Pommier - <pommier@volnay.stortek.com> for contributing this. - - * man/html: I've just used the man2html programs to generate the - html documentation from the man3 directory. It seems to work - pretty well. - - * ace/Assert.h: Added a forward declaration for class ACE_Log_Msg - to fix problems NuMega preprocessing. Thanks to Mike Flinn - <mike.flinn@smtpgate.aws.waii.com> for finding this. - - * ace: Implemented about 1/3rd of the "dump" methods for the - various ACE classes. - - * ace/Acceptor.cpp (info): Fixed a bug -- should use PR_AD rather - than ACE_INET_Addr since this is used for SPIPEs as well... - - * ace/Synch_T.cpp (ACE_TSS): If ACE_Thread::keycreate () fails - then we do an fprintf() and return at the moment. It doesn't do - any good to do an ACE_Log_Msg operation since those all require - thread-specific storage and this will just cause a recursive - problem... - - * ace/OS.cpp: Removed a memory leak in ACE_OS::thr_destory_tss() - that was caused by forgetting to delete each ACE_TSS_Key_Info - object when we no longer needed it. Thanks to Mike Flinn - <mike.flinn@smtpgate.aws.waii.com> for finding this. - - * ace/OS.cpp: Added a new method to class ACE_OS called - thr_keyfree(). This enables us to free up a thread-specific - storage key on Win32 (it isn't implemented on the UNIX - platforms). - - * ace/ACE.cpp (timestamp): In order to get ACE_OS::timestamp to - work on Win32, the wMonth, wDay, wYear structure members were - added to the sprintf statement. Thanks to Mike Flinn - <mike.flinn@smtpgate.aws.waii.com> for this fix. - - * examples: Changed all uses of ACE::send_n (1, ...) to - ACE_OS::write (ACE_STDOUT, ...) to avoid problems with NT's - hacked support for sockets and HANDLEs. Thanks to Bernd Hofner - <hofner@pd.et-inf.uni-siegen.de> for noticing this. - -Sun Mar 17 00:43:14 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/CORBA_Handler.cpp (handle_input): Fixed the CORBA_Handler to - use send()/recv() rather than read()/write(). - - * ace/Process_Manager: put the hooks in for the forthcoming ACE - Process Manager, which will provide a service similar to the - ACE_Thread_Manager, except that it will work for processes, not - threads. - - * netsvcs: all the ACE network services appear to be working - again... - - * man: Completely regenerated all the manual pages to reflect all - the most recent changes. - - * ace/OS.h: Created a new macro called ACE_DEFAULT_REACTOR_SIZE. - This is useful for two reasons (1) it centralizes this value in - one place in ACE and (2) removes a horrible circular dependency - between the Service_Config.h and Reactor.h... - - * ace/Strategies: Added new strategies to handle "scheduling" of - Svc_Handlers launched by a Strategy_Acceptor. In this context, - scheduling refers to "suspending" and "resuming" Svc_Handlers. - There are several alternative strategies ranging from (1) - suspending/resuming a single handler, (2) suspending/resuming - all the handlers in a Reactor, and (3) suspending/resuming all - handlers controlled by a Thread_Manager. This very powerful - feature makes it simple to write ACE_Network_Services that can - control all their handlers in one fell swoop... - - * ace/Task: Added new accessors/mutators to get/set the - Thread_Manager and the Message_Queue associated with a Task. - This makes life easier and more abstract in subclasses and - elsewhere. - - * ace/Reactor: added an iterator to the ACE_Handler_Repository. - This makes it possible to implement the suspend_handlers() and - resume_handlers() very efficiently on both UNIX and Windows NT. - - * ace/Reactor: Added two new methods called suspend_handlers() and - resume_handlers(). These methods suspend and resume all the - active Event_Handlers in the Reactor in one fell swoop. - - * ace/Reactor.i (suspend_handler): Fixed a bug in the Reactor - where we were not factoring out the code for suspend_handler() - appropriately with respect to locking. - - * netsvcs/Logging/Server_Daemon/Thr_Logging_Handler: Enhanced the - threaded logging service so that all active threads can be - automatically suspended and resumed via the ACE_Service_Config - svc.conf file. - - * netsvcs/Logging/Server_Daemon/Logging_Handler.cpp: Rewrote the - ACE Logging service to use the new ACE_Strategy_Acceptor - implementation. This greatly reduced duplicate code. There's - almost nothing left in this directory save the actual service - itself! - - * netsvcs/Tokens: Rewrote the ACE Token service to use the new - ACE_Strategy_Acceptor implementation. This greatly reduced - duplicate code. There's almost nothing left in this directory - save the actual service itself! - - * netsvcs/Naming: Rewrote the ACE Naming service to use the new - ACE_Strategy_Acceptor implementation. This greatly reduced - duplicate code. There's almost nothing left in this directory - save the actual service itself! - -Sat Mar 16 20:02:08 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * netsvcs: Created a new subdirectory off of $WRAPPER_ROOT and put - all the ACE network services (e.g., Time, Logging, Naming, and - Tokens) into that directory. These services all instantiate the - new ACE_Strategy_Acceptor implementation, which greatly - simplifies their behavior and code. - - * ace/Acceptor: Made some enhancements to the - ACE_Strategy_Acceptor in order to make it more suitable for use - as a generic "Service" launcher. This class now defines common - behavior for all the ACE network services (e.g., Time, Logging, - Naming, and Tokens). - - * apps/Token_Server: Made the main Token_Server application be - dynamically linked if there's a valid svc.conf file. - - * apps/Name_Server/Name_Server: Made the Server_Test a - "well-behaved" service. Previously, it block in a private event - loop within Name_Server::run(), which was called by - Server_Test::init() when the service was linked dynamically. - This obviously doesn't work correctly since it means that we - can't dynamically link any other services after this one! The - new version is "event-loop" friendly since it uses the main - Service_Config::run_event_loop() method. - - * ACE-categories: Added a new emacs "outline" file that - illustrates how the filenames in $WRAPPER_ROOT/ace cluster into - class categories. Thanks to Chris Eich - <Chris_Eich@optilink.optilink.dsccc.com> and Alex V. Maclinovsky - <alexm@teltrunk1.tait.co.nz> for helping create this. - - * ace: Split ACE into two libraries: libACE and libACE_svcs. - libACE contains the "core" ACE components. libACE_svcs contains - the client-side layered services (e.g., naming service, token - service, etc.). There are two reasons for doing this: - - 1. It reduces the size of ACE for many common usecases (i.e., - most people aren't using the naming service or the token - service). Any future layered services in ACE will be placed - into the libACE_svcs library rather than libACE. - - 2. It works around annoying compiler bugs with lame compilers - like HP/UX C++. Now, if those compiles can't compile the - token service (which is very template intensive) it won't - affect the core ACE library components. This improves the - portability of ACE. - - * Added -lACE_svcs to the ./apps/{Token_Server,Name_Server} and - ./examples/{Tokens,Naming} Makefiles to account for the new - libraries. Note that no source code changes are required... - -Fri Mar 15 00:03:48 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/Name_Server/server/Name_Handler.cpp (recv_request): Fixed - the same problem as occurred in Token_Handler (these both come - from the same source...). - - * apps/Token_Server/Token_Handler.cpp (recv_request): There was a - subtle bug in the Token_Handler that stems from my old code. - The line - - n = this->peer_.recv ((void *) (((char *) &this->token_request_) - + sizeof (ACE_UINT32)), - length); - - This should actually be: - - n = this->peer_.recv ((void *) (((char *) &this->token_request_) - + sizeof (ACE_UINT32)), - length - sizeof (ACE_UINT32)); - - since length was read already. The old way tried to read 4 - bytes too much. Thanks to Jesper for noticing this. - - * ace/Connector.cpp (connect_svc_handler): Modified the connector - so that it automatically calls the close () method of the - Svc_Handler when the connection fails abortively. This makes - the semantics the same for synchronous and asynchronous - connection invocation modes. Thanks to Irfan for insisting on - this! - - * apps/Token_Server/Token_Acceptor.cpp (handle_input): Changed - return type from int to ACE_HANDLE for NT compatibility. Thanks - to Jesper for this insight. - - * ace/OS.h: The defines for ACE_LACKS_MODE_MASKS (OS.h) were only defined - when !ACE_WIN32. This has been fixed. Thanks to Irfan for - spotting this too. - - * ace/OS.i (mmap): made a small change to ACE_OS::mmap to fix NT - portability problem (new variable added:nt_flags). Thanks to - Irfan for spotting this. - - * ace/Local_Tokens.h: Added #include "ace/Map_Manager.h" after - line 41 in Local_Tokens.h to allow ACE to compile correctly with - the horrid HP/UX compiler. Thanks to Neil Cohen for figuring - this out (what a trooper!). - - * ace/Local_Tokens.cpp (ACE_TPQ_Entry *): Replace - - return ACE_TSS<ACE_TPQ_Entry>::operator ACE_TPQ_Entry *(); - - with - - return (ACE_TPQ_Entry *) (*((ACE_TSS<ACE_TPQ_Entry> *) this)); - - to work around problems with MSVC++ 4.0 when the browse option - is enabled. Thanks to Kirk Sinnard <1764@mn.lawson.lawson.com> - for this fix. - - * ace/config-sunx86-sunc++-4.x.h: Swapped the lines - - // Compiler/platform supports SVR4 signal typedef. - //#define ACE_HAS_SVR4_SIGNAL_T - #define ACE_HAS_CONSISTENT_SIGNAL_PROTOTYPES - - to - - // Compiler/platform supports SVR4 signal typedef. - #define ACE_HAS_SVR4_SIGNAL_T - //#define ACE_HAS_CONSISTENT_SIGNAL_PROTOTYPES - - to avoid an error using ProWorks C++ 4.0.1 (w/ patches) which - blow up in the Signal.x stuff with a prototyping error. Thanks - to John P. Hearn <hearn_j@sat.mot.com> for this recommendation. - - * ace/Shared_Memory.h: The conditional compilation wrapper was out - of date, so I renamed it. Thanks to Alex V Maclinovsky - <alexm@teltrunk1.tait.co.nz> for reporting this. - -Thu Mar 14 23:18:59 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Thread.h: There was a bug in the ACE_Thread class. I - attempted to make the class uninstantiable by making the - constructor private. However, the statement was: - - private: - Thread (void); - - which is not the definition of the ctor! The code compiled - since it thinks Thread is a member function. As a result, you - could instantiate a object of ACE_Thread class, but no longer... - Also added this to the !defined (ACE_HAS_THREADS) arm of the - conditional compilation. Thank to Sandeep Joshi - <sandeepj@emailbox.att.com> for noticing this. - - * ace/Log_Record.i (decode): Fixed a stupid typo where htonl - (this->length_) should have been htohl (this->length_)... - Thanks to Audun Tornquist <Audun.Tornquist@iu.hioslo.no> for - noticing this. - -Tue Mar 12 14:51:39 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Name_Request_Reply.cpp (decode): Added ntohl and htonl calls - wherever data was being exchanged. - -Sat Mar 9 17:49:51 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * ace/OS.i (cond_wait): Updated the Win32 implementation to - correspond precisely with the UNIX semantics where the mutex is - always reacquired even when errors occur. - -Mon Mar 4 23:03:37 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * INSTALL: updated the win32 to describe building test - applications. - -Mon Mar 4 16:17:05 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Local_Name_Space.cpp (resolve): Fixed a small bug. The type - field in resolve was copying extraneous stuff (because of being - kept around as a wchar_t). So I added a new method to the class - ACE_NS_String called len() which simply returns len_. Using this - I can now do a strncpy of len bytes for type (instead of a - simple strcpy) and then null-terminate the string to remove the - garbage. - -Thu Feb 29 23:41:04 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * ace/Token_Request_Reply.cpp: Fixed a byte-order bug which was - showing up on intel platforms. - - * ace/Remote_Tokens.cpp: Fixed a race condition in - ACE_TSS_Connection which was munging mt token server clients. - - * examples/Tokens/mutex/*: The Token Server example applications - now use ACE_Thread_Manager, which should make them portable to - Win32. - - * apps/Token_Server/Token_Server.cpp: The Token Server is now a - Service_Object which can be dynamically linked. - - * ace/OS.i: Win32 ACE_OS:: signal methods now return 0 instead of - -1. So, calls to signal code succeed, but do nothing useful. - -Thu Feb 29 20:38:32 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/Logger/Server_Daemon/Server_Logger.cpp - (handle_logging_record): There was a typo where - ACE_LACKS_STATIC_DATA_MEMBER_TEMPLATES was incorrectly spelled. - This caused problems on HP/UX. Thanks to Neil Cohen for - finding this. - -Wed Feb 28 11:41:49 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Mem_Map.cpp: Fixed a nasty bug with Win32 memory mapping... - It turns out we need to be very careful when remapping a - previously mapped region if the MapViewOfFile we're trying to - establish *grows* beyond what was originally mapped with - CreateFileMapping(). The new scheme seems to work correctly - with both UNIX and Win32. - - * ace/OS.h: apparently when using MFC library functions it - is not possible to include windows.h. Instead, users - must include AFX.h. Therefore, I've modified OS.h to - include the following: - - #if !defined (__AFX_H__) - #include <windows.h> - #endif /* __AFX_H__ */ - - Thanks to Patty Genualdi (genualdp@agcs.com) for pointing this - out. - - * ace/Memory_Pool.cpp: Modified init_acquire() so that it calls - ACE_Mem_Map::open() rather than ACE_Mem_Map::map() the first - time. This ensures that the file is mapped correctly. - - * ace/Mem_Map: Added a new method called open() that creates/opens - a file without actually mapping it. - - * ace/SOCK_Dgram_Mcast.cpp (make_multicast_address): Added - new support for Windows NT. - - * ace/Memory_Pool: reimplemented ACE_MMAP_Memory_Pool so that uses - ACE_Mem_Map. This ensures that we can leverage all the work - that went into making ACE_Mem_Map work on Win32. - - * ace/Memory_Pool.cpp (map_file): Modified the code so that we - always unmap the file before trying to remap it. This avoids - problems with Win32... - - * ace/Mem_Map: Modified the implementation of ACE_Mem_Map so that - it takes advantage of the improved features in ACE_OS::mmap. - Also added new a method that returns the memory-mapped addr more - easily. - - * ace/OS: Modified the ACE_OS::mmap() method so that it is more - efficient for remapping files on Win32. - - * ace/OS.h: renamed the type QWORD to ACE_QWORD to avoid namespace - pollution. Thanks to Patty Genualdi (genualdp@agcs.com) for - pointing this out. - - * ace/OS.h: Changed the value of the SIGPIPE emulation for Win32 - to match the UNIX value in order to avoid problems. Thanks to - Jesper for noticing this. - - * apps/Token_Server: Fixed misuse of int for ACE_HANDLE in various - places. Thanks to Jesper for noticing this. - - * Renamed the ./tests directory to ./examples to make way for the - new ACE regression tests. These tests will go into the new - ./tests directory. - - * ace/Mem_Map.cpp: Added a destructor and a close() method that - closes down the file HANDLE if we allocated it. This is useful - to prevent descriptor leaks. Thanks to Irfan for suggesting - this. - - * ace: Made a number of changes to remove unreferenced parameters - from ACE methods. This eliminates zillions of warning from the - HP/UX compiler. Thanks to Neil Cohen for reporting this. - - * ace/Local_Name_Space.cpp (resolve): revised some code to work - around bugs with the HP/UX compiler... Thanks to Neil Cohen for - this workaround. - -Tue Feb 27 21:06:09 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.i: The Win32 CreateFile does not handle the return you - would expect when the file exists. You would expect EEXISTS (17 - in UNIX) but the GetLastError is set to 80 - (ERROR_FILE_EXISTS). Therefore, I changed ACE_OS::open to map - ERROR_FILE_EXISTS onto EEXIST. This is only a partial solution, - however. There must be a better way to handle this! - - * ace/Mem_Map.cpp (ACE_Mem_Map): Fixed a bug with one of the - ACE_Mem_Map destructors that was causing problems due to the - fact that base_addr_ wasn't being initialized to 0. Thanks to - Karlheinz for noticing this. - - * ace/Signal.i: signals on AIX cannot use sigprocmask() in any - multithreaded programs. Instead, the call - ACE_OS::thr_sigsetmask() should be used since it is used to - update the thread signal mask. This comes up only in the - Sig_Guard constructor and destructor. Therefore, I #ifdef the - call under the ACE_MT_SAFE macro, using sigprocmask() in the - #else case. Thanks to Chris Lahey for reporting this. - - * tests: removed all uses of ACE_OS::join (0, ....) in ACE and - replaced them with ACE_Thread_Manager::wait() calls. This - ensures that the ACE code is portable to Win32 and POSIX - pthreads! - - * ace/Dynamic_Service.cpp: Added a #include of - "ace/Service_Config.h" to work around problems with HP/UX. - Thanks to John Morey for reporting this. - -Sun Feb 25 12:10:38 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/Token_Server: changed the name token_server.cpp to main.cpp - to avoid a name clash on Win32... - - * man/man3: updated all the ACE manual pages to reflect the - most recent changes. - - * ace/OS.i: Implemented the cond_timedwait() method correctly in - ACE_OS. This method should now do the right thing with respect - to blocking, polling, and timewaits for Win32. - - * ace/OS.i: Modified the Win32 implementation of all the - socket-related wrappers in ACE_OS. The new implementation very - cleverly sets errno to the result of WSAGetLastError() if a - socket-related call fails. Since all of the WinSock errors are - mapped into their equivalent UNIX errno values this enables - socket applications to work portably for UNIX and Win32. - - * ace/Malloc_T.cpp (ACE_Malloc): Improved error reporting for - cases where the Memory_Pool::init_acquire() fails (e.g., if the - backing store was already created by another user and we don't - have permission to access it...). - - * ace/Task: modified Task.h so that it is no longer necessary to - write #include "ace/Synch_T.h" in order to use ACE_MT_SYNCH, - etc. - - * ace/SOCK.cpp (DllMain): Added a clever "Schwartz counter" to - make sure that the WinSock library is correctly initialized, - even if we're not using ACE as a DLL!!! - - * tests/Mem_Map/file-reverse: got the file reverse test program - working. The ACE_Mem_Map class should now be ported to Win32... - - * ace/OS.i (open): Changed how the O_CREAT flag was handled - to give it UNIX semantics... - -Sat Feb 24 12:55:27 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/UPIPE_Stream.cpp (recv): Fixed a signed/unsigned mismatch. - There should be no more mismatches in ACE... - - * ace/Name_Proxy.cpp (recv_reply): Fixed a signed/unsigned - mismatch. - - * ace/Message_Block.cpp (copy): Fixed a signed/unsigned mismatch. - - * ace/INET_Addr.cpp (get_host_name): Changed the type of the - hostnamelen parameter from int to size_t to be more "abstract." - This will also prevent a warning from the MSVC++ compiler. - - * apps/Logger/Client_Daemon/Client_Logger.i: Fixed a braino with - network byteoder that was causing Client_Logger::send() to fail - on INTEL boxes. Thanks to Bryon G. Rigg - <bgrigg@opus.bcbnet.com> for finding this. - -Fri Feb 23 01:59:34 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.i: Enhanced mmap() to give the same semantics as UNIX - mmap() by using MapViewOfFileEx(). Also greatly improved the - UNIX emulation capabilities so that mmap() now has the same API - for UNIX and Win32. - - * ace/Time_Value: Added functions to constructor and conversion - from/to Win32 FILETIME. This enables us to reuse those 100ns - conversions in ACE_Profile_Timer. - - * ace/Time_Value: Fixed a problem with these: - - // True if tv1 < tv2. - - INLINE int - operator < (const ACE_Time_Value &tv1, - const ACE_Time_Value &tv2) - { - ACE_TRACE ("operator <"); - return tv2 > tv1; - } - - This should be "tv2 >= tv1". Same problem was fixed with - operator <=. - - * ace/Profile_Timer.i, fixed the following: - - this->end_time_ = ACE_OS::gettimeofday (); - this->last_time_ = this->end_time_; - this->last_usage_ = this->end_usage_; - ACE_OS::getrusage (RUSAGE_SELF, &this->end_usage_); - - This will overwrite end_time before it is saved to - last_time... - - * tests/Threads: Added Jesper's test for readers/writers locks. - The test adds a number of reader and writer threads. When - active, writers modify a shared variable and verify that only - one writer and no readers are active. When active, readers - check that no writers are active and that the shared data is - never changed. The test passes for different ratios of - readers/writers, and debug output shows that several readers are - allowed simultaneously. Or, in other words, we have an - indication that it should work. - - * ace/OS.i: Added Win32 implementations of getpid(), fork(), - lseek(), dup(), cond_timedwait (), getrusage () - - * ace/OS.i: Modified all the ACE_OS::str* routines so that they no - longer do an ACE_OSCALL_RETURN. This can lead to weird bugs... - Thanks to Jesper for noticing this. - - * ace/config-sunos4-sun4.1.4.h: Added a new config file that - should work with SunOS 4.x... Also added support for SunOS - 4.1.4. Thanks to Mick Adams (eeimas@eei.ericsson.se) for help - with this. - -Thu Feb 22 18:58:36 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * tests/Naming/Client/Name_Service.h (ACE_Service_Object): - Modified test application to make use of ACE_Dynamic_Service. - - * ace/Dynamic_Service.h: Added a new class called Dynamic_Service - which provides a general interface to add and retrieve arbitrary - things into the ACE service repository. - - * apps/Name_Server/README: Rearranged files so that Name_Server - and Name_Handler are now contained in the server directory under - apps and are no longer under /ace. Also, the Dump_Restore - directory has been moved under /tests/Naming. - -Thu Feb 22 01:56:46 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/INET_Addr.cpp (set): Fixed a byteorder bug in ACE_INET_Addr - that was causing problems when ACE was used on Win32 running on - Intel platforms... - - * ace/Mem_Map.cpp (map_it): Fixed ACE_Mem_Map so that it will work - correctly on Win32. - - * ace/SOCK_Stream.i: Changed the implementation of the Win32 - versions of send() and recv() so that they will never use the - read() and write() calls. This works around limitations with - Win32, which can't do a ReadFile() or WriteFile() - *synchronously* with a SOCKET. - - * Changed all occurrences of read (0, ...) to read (ACE_STDIN, - ...) and all occurrences of write (1, ...) to write - (ACE_STDOUT, ...) in order to be compatible across UNIX and - Win32. - - * tests/ASX/Event_Server: Fixed up all the socket I/O calls so - that they use the WinSock send()/recv() methods rather than - ReadFile and WriteFile... - - * ace/OS.i: Updated open() to correctly emulated UNIX open() - semantics on Win32. - - * ace/OS.cpp (thr_exit): Added support to the NT port so that - thr_exit() doesn't endup doing multiple deletions of the same - object. Thanks to Karlheinz for this fix. - - * ace/OS.h: Moved the location of ACE_MAXCLIENTIDLEN so that - MAXHOSTNAMELEN would be correctly visible for NT. - - * ace/Reactor.cpp: Added a temporary fix for the fact that - writev() and readv() don't work correctly yet on NT. The - solution is to replace write() with two writes() and readv() - with two reads() for the Reactor's notification scheme. A - better solution should be forthcoming. - - * ace/Reactor.cpp: Made sure to initialize the timer_queue_ to 0 - in the constructors so that the Reactor's destructor can avoid - crashing horribly if the constructor fails. Thanks to Karlheinz - for pointing out the need for this. - - * ace/SOCK.cpp: Added support for WSAStartup for using WinSock - within the ACE_SOCK class. - -Wed Feb 21 21:05:55 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/ACE.cpp (bind_port): Made a quick fix to work around the - fact that NT doesn't set errno... - - * ace/OS.i (mmap): Fixed a bug in mmap for the NT port. It should - return MAP_FAILED on error rather than 0 to be equivalent to the - UNIX version. Thanks to Irfan for spotting this. - -Mon Feb 19 00:31:42 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Typed_SV_Message.i (ACE_Typed_SV_Message): Modified the - constructor calls so that length_ and max_size_ are correctly - set when created. Thanks to Alexandre Karev - <akg@na47sun05.cern.ch> for reporting this. - - * ace/SV_Message_Queue.i (remove): fixed bug in - ACE_SV_Message_Queue::remove method where `internal_id_' member - was modified *BEFORE* it was used the last time in - ACE_SV_Message_Queue::control. Thanks to Alexandre Karev - <akg@na47sun05.cern.ch> for reporting this. - - * ace/Typed_SV_Message.i (length): Fixed a minor typo that caused - a bigger bug ;-). Thanks to Alexandre Karev - <akg@na47sun05.cern.ch> for reporting this. - - * ace/OS.h: Added new macros that allow programs to portably - access stdin, stdout, and stderr HANDLEs on Win32 and UNIX as - follows: - - #if defined (ACE_WIN32) - #define ACE_STDIN GetStdHandle (STD_INPUT_HANDLE) - #define ACE_STDOUT GetStdHandle (STD_OUTPUT_HANDLE) - #define ACE_STDERR GetStdHandle (STD_ERROR_HANDLE) - #else - #define ACE_STDIN 0 - #define ACE_STDOUT 1 - #define ACE_STDERR 2 - #endif /* ACE_WIN32 */ - - * ace/INET_Addr.i: modified the return value of get_port_number so - that it returns the value in host byte order. This has actually - been a latent bug in ACE for years, but it only surfaced - recently after porting to NT on the Intel instruction set (which - is "little-endian"). - - * tests/ASX/Event_Server: Merged in the latest changes to the - Event_Server tests, which enable it to compile on Windows NT. - Now, I just need to get it working on NT... - - * Updated all of ACE to use the new ACE_ASSERT rather than assert. - - * ace/Assert.h: Added a new file and a new macro called - ACE_ASSERT. This uses the ACE_Log_Msg Singleton to provide a - more consistent means to do assertions. Thanks to Alexandre - Karev <akg@na47sun05.cern.ch> for suggesting this. - - * ace/Log_Msg.cpp (log): added for method ACE_Log_Msg::log lines - to skip the `sprintf' part for %N - file name and %l - line - number format specifiers. Thanks to Alexandre Karev - <akg@na47sun05.cern.ch> for reporting this. - - * Remote_Name_Space: Removed an initalizer to ACE_WString that was - driving the HP/UX compiler nuts. - -Sun Feb 18 18:11:22 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Synch.h (ACE_Null_Condition_Mutex): Added a missing body to - the wait() method. Thanks to Byron Riggs for noticing this. - -Sat Feb 17 19:10:06 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * tests/Naming/README (client): Added description for new - features, including support for list_values and list_types. Also - added a small description about test programs using DLL. - - * ace/Name_Request_Reply.cpp (decode): Fixed a small bug in - ACE_Name_Request::decode. type_ was not null terminated causing - some garbage to be returned. - -Thu Feb 15 14:57:06 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Remote_Name_Space.cpp: Changed names of some parameters to - comply with ACE syntax. - -Wed Feb 14 13:36:31 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Local_Name_Space.cpp (resolve): Type support has been added - to Name_Server. A new class called ACE_NS_Internal was created to - keep value and type information. - -Fri Feb 9 17:12:00 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * "Officially" released ACE 4.0 - - * ace/OS.i (sema_post): Fixed a bug in the NT port. - - #elif defined (ACE_HAS_WTHREADS) - return ::ReleaseSemaphore (*s, 1, 0); - #endif /* ACE_HAS_STHREADS */ - - This returns 1 for success, and disturbs cond_broadcast... - This was replaced by: - - #elif defined (ACE_HAS_WTHREADS) - return ::ReleaseSemaphore (*s, 1, 0) ? 0 : -1; - #endif /* ACE_HAS_STHREADS */ - - Thanks to Jesper S. M|ller (stophph@diku.dk) for this. - - * ace/OS.i (cond_init): Fixed a bug in the NT condition synch - code, as the initial count of the semaphore was 1. This gives an - inconsistent condition: The first waiter went straight through... - Change in ACE_OS::cond_init: - - if (ACE_OS::sema_init (&cv->sema_, 0, type, name, arg) != 0) - return -1; - - Thanks to Jesper S. M|ller (stophph@diku.dk) for this. - - * ace/Singleton.cpp: Fixed a stupid bug that was caused by failure - to #include "ace/Synch_T.h"... Thanks to Neil Cohen and Byron - Riggs for giving me insights on what the problem was. ACE now - compiles on HP/UX. - -Fri Feb 9 11:07:04 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * tests/Naming/server/Server_Test.cpp (init): Modified server - tests to dynamically link Naming Services. Both client and - server tests now make use of the ACE dynamic linking mechanisms. - - * ace/Local_Name_Space.cpp: Added list_values() to Name - Server. The functionality is very similar to list_names (returns - list of values that match a pattern). - - * tests/Naming/client/Client_Test.cpp (bind): Replaced all uses of - cerr and cout with ACE_ERROR, ACE_ERROR_RETURN, and ACE_DEBUG. - Split the file Client_Test.cpp into two files -- Client_Test.cpp - and Name_Service.cpp (similarly .h file) each containing the - corresponding class. Modified svc.conf to work with the changes. - -Thu Feb 8 02:05:26 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Log_Msg.cpp (log): Enhanced the Log_Msg class so that it - supports "nested" calls via %r. If SILENT mode enabled, nested - outputs will enclosed in {..} brackets in thread-specific - storage. Thanks to Alexandre Karev <akg@na47sun05.cern.ch> for - suggesting this. - - * ace/Synch: Added a new class called ACE_Null_Condition_Mutex. - This is necessary to fix bugs with stupid compilers... Thanks - to Zusman Mark <marklz@rotem.technion.ac.il> for reporting this. - - * tests/Naming/client: made a first pass implementation of a - client application that dynamically links in a Naming_Context - based on information provided by the svc.conf file. - - * ace/Name_Options: Fixed yet more problems with dynamic memory - management. The old version didn't make a copy of the strings - it was passed and this caused major problems. - - * ace: Fixed a whole slew of problems with the ACE Name Server - stuff that arose from inconsistent use of const char * vs. char - *... - -Wed Feb 7 00:58:45 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/CORBA_Handler.cpp (ACE_MT_CORBA_Handler): Added new - enhancements to ACE_MT_CORBA_Handler to make it work correctly - with Windows NT. Thanks to Irfan for making these changes. - - * ace/Connector.cpp (fini): Make another workaround for bugs with - MSVC++ 2.0... - - * ace/SPIPE_Connector.cpp (connect): Added a call to ACE_CLR_BITS - (flags, O_CREAT) to make darn sure that the O_CREAT flag is not - set. Thanks to Chris Cleeland for suggesting this. - -Tue Feb 6 01:40:29 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.h: added a new prototype to OS.h that should help with - portability to nasty platforms with broken rand_r() definitions. - Thanks to Aurelio Nocerino - <aurelio@irsipcs2-27-le0.irsip.na.cnr.it> for suggesting this. - - * Local_Tokens: Changed all uses of enumerals MAXTOKENNAMELEN and - MAXCLIENTIDLEN to symbol #defines ACE_MAXTOKENNAMELEN and - ACE_MAXCLIENTIDLEN. This works around bugs with HP/UX. - Thanks to Neil Cohen for reporting this problem. - - * ChangeLog: split the ChangeLog files into 4 separate files -- - one for '96, '95, '94', and '93. Hard to believe I've been - working on this stuff for so long! - - * ace/OS: Fixed the use of ::memset to replace sizeof buffer with - sizeof (ACE_SERVENT_DATA) and sizeof (ACE_HOSTENT_DATA). This - fixes bugs that surfaced on AIX. Thanks to Chris Lahey for - finding these. - - * ace/SPIPE_Addr.cpp (ACE_SPIPE_Addr): Fixed a bug in - SPIPE_Addr::SPIPE_Addr(const SPIPE_Addr&). What happens is that - when the size is calculated it does not take into account the - required zero byte at the end of the rendezvous_ member. Thanks - to Chris Cleeland <chris@envision.com> for reporting this. - - * ace/Local_Tokens: Had to move all ACE_Token_Proxy methods from - Local_Tokens.i to Local_Tokens.cpp and remove INLINE - otherwise - gcc reported them as undefined methods during linkage stage. - Thanks to Zusman Mark <marklz@rotem.technion.ac.il> for - reporting this. - - * ace: Changed ACE_Name_Request_Reply::LAST to - ACE_Name_Request_Reply::MAX_ENUM to avoid problems with name - conflicts on OSF/1. Thanks to Eshel Liran - <liran@bimacs.cs.biu.ac.il> for suggesting this. - - * ace/Synch_T: Fix all definitions of ACE_Atomic_Ops so that they - compile correctly on platforms that lack threads! Thanks to - Alexandre Karev <akg@na47sun05.cern.ch> for noticing this. - - * include/makeinclude: Added a new config file from Bryon G. Rigg - <bgrigg@opus.bcbnet.com>, which should allow ACE to build on - Linux. - - * ace/Remote_Tokens.cpp: Moved ACE_TSS_Connection to - Remote_Tokens.h to avoid problems with AIX. Thanks to the - ever-vigilant Chris Lahey for reporting this. - -Mon Feb 5 23:34:42 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * Added CORBA_Ref.h which contains the new class ACE_CORBA_Ref. - This class provides a nice wrapper for making the use of Orbix - object references more transparent. This is done by automating - the release and duplicate calls. - -Mon Feb 5 15:43:17 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: added Prashant's latest changes to the Name_Handler*, - Naming_Context*, and Remote_Name_Space*. These changes make it - possible to retrieve lists of values based on a pattern, which - can be a regular expression. - - * Moved the apps/Name_Server/Client-Server tests into tests/Naming - and most of the apps/Token_Server/* tests into tests/Tokens to - conform to Karlheinz's testing style. - - * ace: Modified a number of files in ACE to make it compile - correctly with MSVC++ 2.0. - -Sun Feb 4 23:58:43 1996 Douglas C. Schmidt (schmidt@mambo.cs.wustl.edu) - - * ace/Reactor: Generalized ACE_Null_Callback to work correctly - with Windows NT (which lacks pipes). The new design uses the - ACE socket wrappers for NT. It requires very few changes to the - code to handle NT now! Also changed the name to - ACE_Notification_Handler, which is more descriptive. - -Sun Feb 4 14:47:50 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Remote_Tokens.cpp: Reworked ACE_Singleton to avoid - portability problems on compilers like GCC. - -Thu Feb 1 12:47:46 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Remote_Tokens.cpp: Generalized the parameters passed into - ACE_Singleton so they would compile on HP/UX and other platforms - that lack threads. Thanks to Neil Cohen for noticing the - problem. - -Wed Jan 31 22:49:13 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Modified a number of minor things in ACE to get it to - compile successfully with Windows NT MSVC++ 4.0. Updated the - INSTALL file to explain this process better... - -Tue Jan 30 01:12:07 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/CORBA_Handler.cpp: changed things so that no diagonistic - messages are printed. - - * Regenerated all the ACE manual pages to bring them up to date - with the recent changes. - - * ace/Malloc.h: Modified the ACE_Malloc header file so that it - works correctly when ACE_MALLOC_STATS is enabled. Thanks to - Alexandre Karev <akg@na47sun05.cern.ch> for reporting this. - - * ace/OS.cpp (mutex_lock_cleanup): removed the leading & before - p_lock. Thanks to Chris Lahey for noticing this. - - * ace: Added the new ACE_Singleton class. This class uses the - Adapter pattern to turn ordinary classes into Singletons - optimized with the Double-Check pattern. - - * Added Tim's latest Token Server changes (which include support - for local and remote mutexes and readers/writer locks) and - Prashant's latest Name Server changes (which allows the contents - of a Name Server to be dumped and restored to/from an ASCII - file). - -Mon Jan 29 02:22:23 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Handle_Set: Changed MAX_SIZE and WORD_SIZE to MAXSIZE and - WORDSIZE to avoid name collisions with HP/UX. Thanks to Byron - Rigg <bryon_rigg@mail.telecorpsys.com> for suggesting this. - - * ace/Time_Value.h: Added a new config symbol ACE_HAS_SVR4_TIME to - differentiate between UNIX platforms that support "POSIX_TIME" - (i.e., timespec_t) and those that support "SVR4_TIME" (i.e., - timestruc_t). This is necessary to work around HP/UX... Thanks - to Byron Rigg <bryon_rigg@mail.telecorpsys.com> for suggesting - this. - - * ace/config-hpux-10.x.h: config-hpux.h has now been renamed to - config-hpux-10.x.h and config-hpux-9.x.h. Thanks to Byron Rigg - <bryon_rigg@mail.telecorpsys.com> for suggesting this. - - * ace/Synch_T: Added a new method called ts_get() and made both - the operator-> and operator TYPE * call this. I hope this will - fix a bug with HP/UX reported by Neil Cohen... - - * ace/OS.i (dlclose): Added Win32 support for dlclose(). Thanks - to Todd L. Montgomery <tmont@cerc.wvu.edu> for pointing the way - here... - - * ace: Split off the old class ACE_Dynamically_Allocated, renamed - it ACE_Dynamic, put it in a separate file called Dynamic.*. - This is necessary to solve nasty multiple definition problems - with compilers that require the source of template. - - * ace/Synch_T: moved - - template <class TYPE> TYPE * - ACE_TSS<TYPE>::make_TSS_TYPE (void) const - { - return new TYPE; - } - - out from condition compilation block - - #if (defined (ACE_HAS_THREADS) && defined(ACE_HAS_THREAD_SPECIFIC_STORAGE)) - - in file Synch_T.cpp. This class member called in many other - places regardless ACE_HAS_THREADS and - ACE_HAS_THREAD_SPECIFIC_STORAGE defined or not... - - * ace/Name_Handler.cpp: Changed the use of the "inherited" typedef - to fully expand to ACE_Svc_Handler<ACE_SOCK_STREAM, - ACE_NULL_SYNCH>. This is necessary to workaround bugs with AIX. - Thanks to Chris Lahey for reporting this. - - * tests and apps: Fixed an odd problem that only surfaced recently - with GNU G++. Apparently, it doesn't like function-style casts - of the form ACE_SignalHandler (foo), but will accept - (ACE_SignalHandler) foo. Since both approaches are equally good - for what I'm doing, I've updated all the code in ACE to be more - portable. - -Sun Jan 28 12:24:58 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * tests/Shared_Malloc/test_malloc.cpp (spawn): when forming - argv[] for execv, moved - - argv[ ... ] = Options::instance ()->debug () ? "-d" : ""; - - to the end of the vector just before terminator. This will - allow to pass rest of arguments to exec if -d switch not - specified. Thanks to Alexandre Karev <akg@na47sun05.cern.ch> - for reporting this. - - * tests/Shared_Malloc/Malloc.cpp: To avoid conflict with - ACE_DEFAULT_SEM_KEY in OS.h changed SEMA_KEY value in - tests/Shared_Malloc/Malloc.cpp to ACE_DEFAULT_SEM_KEY + 1. - Thanks to Alexandre Karev <akg@na47sun05.cern.ch> for reporting - this. - - * ace/SV_Semaphore_Complex.i: Changed all arguments in calls like - - this->acquire( n+2 ) - and - this->tryacquire( n+2 ) - to - this->acquire( n ) - and - this->tryacquire( n ) - . - Since the semaphore number is incremented by 2 in - SV_Semaphore_Complex::acquire - and - SV_Semaphore_Complex::tryacquire - - when SV_Semaphore_Simple::(acquire/tryacquire) is called. - Thanks to Alexandre Karev <akg@na47sun05.cern.ch> for pointing - this out. - -Sat Jan 27 16:14:27 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Read_Buffer: Added a new component that efficiently reads in - an artibrarily large buffer from a file up to an including a - termination character. Also performs search/replace on single - occurrences a character in the buffer using the priniciples of - Integrated Layer Processing. - -Fri Jan 26 12:01:06 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Thread_Manager: Made a small change to workaround the use of - a struct type for thread_t and hthread_t in HP/UX. Thanks to - Bryon Rigg <bryon_rigg@mail.telecorpsys.com> for noticing this. - -Thu Jan 25 19:54:01 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Svc_Handler: Added some minor changes to account for - limitations with GNU G++. I think the new implementation will - be portable across all C++ platforms. - - * ace/SV_Semaphore_*: Widened the interface of SV_Semaphore* - classes to include a flags parameter. This can be used to pass - in SEM_UNDO, which is important in many applications. Thanks to - Andrew Gilbert <agilbert@csci.csc.com> for suggesting this. - - * ace/Synch_T.cpp: We are forced to "cast away const" inside of of - the ACE_TSS const methods in order to make the ACE_Guard work. - The right thing to do would be to make the lock "mutable" but - that's hopelessly non-portable. - -Thu Jan 25 14:34:12 1996 Douglas C. Schmidt (schmidt@merengue.cs.wustl.edu) - - * ace/Log_Msg: Fixed a minor bug in ACE_Log_Msg that kept - resetting the restart and iostream value no matter what we'd set - it to before. Thanks to Prashant for finding this. - - * bin: Fixed up the Makefile process for the clone program. Now - it builds without having to depend on ACE. Thanks to Brad Brown - (bbrown@rdxsunhost.aud.alcatel.com) for suggesting this. - - * ace/Synch: Modified ACE_Condition*.remove so that cond_destroy() - is called in a loop if the condition variable is BUSY. This - avoids a condition where a condition is signaled and because of - some timing problem, the thread that is to be signaled has - called the cond_wait routine after the signal call. Since the - condition signal is not queued in any way, deadlock occurs - unless this loop is used. Thanks to Chris Lahey for pointing - this out. - - * ace/CORBA_Handler: Made all the methods in ACE_CORBA_Handler - private to make sure that users don't inherit from this class! - Instead, the ACE_MT_CORBA_HAndler and ACE_ST_CORBA_Handler - should be used as Singletons. - - * ace/CORBA_Handler: Added new support for Orbix on Windows - NT. This requires clever use of macros in order to handle - inherent differences between generated code. - - * ace/Svc_Handler: Added a clever idiom that transparently checks - if we were allocated dynamically. This information is used by - the <destroy> method to decide if we need to delete <this>... - The idiom is based on a paper by Michael van Rooyen - (mrooyen@cellnet.co.uk) that appeared in the April '96 issue of - the C++ Report. We've spruced it up to work correctly in - multi-threaded programs by using our ACE_TSS class. - - * ace/config-win32-msvc4.0.h (ACE_LACKS_RECVMSG): Fixed a typo - in the MSVC++ config files. - -Thu Jan 25 02:59:22 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Finally got the frigging library built on SGI. This was a chore - due to compiler bugs, but at least it's another datapoint for - successful cross-platform building... - -Wed Jan 24 00:10:29 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Time_Value.cpp (operator-=): Changed operator += and - operator -= to use const ACE_Time_Value & rather than - ACE_Time_Value &. Thanks to Alex V Maclinvosky for noticing - this. In addition, also changed *all* ACE_Time_Value parameters - to be const ACE_Time_Value &. This should reduce the number of - excess constructors called... - - * ace/OS: Added Chris Lahey's latest changes that introduce POSIX - pthread cancellation cleanup handlers. Also added an herror() - function that is comparable to perror(). - - * ace/OS: (thr_join): Added a new version of thr_join() which - works for Windows NT. Windows NT requires a HANDLE, which is - fundamentally incompatible with other things... - - * ace/Thread_Manager: added two new methods that return the - ACE_Thread_Descriptor corresponding to either a thr_id or a - thr_handle. - - * ace/Thread_Manager: Made the spawn() interface compatible with - the other spawn() interfaces in ACE_OS and ACE_Thread by adding - the hthread_t type. - - * ace/Log_Msg.cpp (log): Fixed things up so that we can now print - out the thread id for all versions of threads! - - * ace/OS: Added a new overloaded version of ACE_OS::thr_self() - that returns the "kernel" thread id. This is necessary on - systems like NT and AIX, which separate kernel thread ids from - user thread ids. Thanks to Chris Lahey for suggesting this. - -Tue Jan 23 01:17:23 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.i (sigwait): Changed the parameter of sigwait() from - const sigset * to sigset *. Thanks to Neil Cohen for chasing - this down on SunOS 5.5.... - - * ace/Malloc_T.cpp: Fixed a typo in bind() whereby - the test if (duplicates == 0 || this->shared_find (name) != 0) - should be if (duplicates == 0 && this->shared_find (name) != 0). - Thanks to the ever vigilant Alexandre Karev - <akg@na47sun05.cern.ch> for reporting this. - - * tests: Fixed all test programs that previously used the "execl" - family of system calls to use the "execv" family instead. - - * ace/OS: Added support for the "execv" family of exec() system - calls. Unlike the "execl" family, these calls are easy to - support since they don't require variadic arguments. I've added - the hooks for the "execl" family, as well, but haven't actually - implemented them yet. - - * ace/Memory_Pool.cpp (ACE_Shared_Memory_Pool): Fixed a bug that - was tickled when pool_name == 0. Thanks to Alexandre Karev - <akg@na47sun05.cern.ch> for reporting this. - - * ace/OS.h: removed FD_SETSIZE from the ACE_WIN32 stuff since this - is defined in winsock.h. - - * ace/OS.cpp (ACE_Spawn_Args): Added "f" to the parameter list. - - * ace/CORBA_Handler: Added a new macro called CORBA_T that masks - the incompatibilities between the version of Orbix on NT and on - Solaris. - - * ace/OS.h: Added support for compilers (like NT) that don't - support "mode masks" (these are used to give symbolic names for - file creation modes passed to open() and creat(). - - * ace/SString.cpp: Added Tim's new copy constructor code for - SString.cpp. This doesn't appear to be strictly necessary , but - it is more explicit and therefore it useful. - - * ace/Map_Manager.cpp: Fixed a bug in Map_Manager that was failing - to call the placement new operator for every element in the map - that was dynamically created by the allocator(). - - * ace/Synch_T: Added Tim's new ACE_TSS implementation. This - version is more flexible than the old one. - -Mon Jan 22 00:03:24 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Time_Value.h: changed a few minor things to get this - compiling again on NT. Thanks to Irfan for helping with this. - - * ace/Synch_Options: Changed all the "accessor" methods to be - const member functions at the request of Irfan. I just know - this is going to cause const cancer... ;-) - - * ace/Acceptor and Connector: Changed all parameters that take - ACE_Synch_Options & to take const ACE_Synch_Options & at the - request of Irfan. - - * ace/OS.i (uname): Added rudimentary support for the uname() - function for Windows NT. If anyone has suggestions on how to - fill in all these fields portably please let me know! - - * ace/Connector.h: Changed a stray -1 to ACE_INVALID_HANDLE. - Thanks to Irfan for noticing this. - - * ace/Profile_Timer.h: Added the keyword "public" to handle one - arm of the conditional compilation that is only exercised on - NT... Thanks to Irfan for noticing this. - - * ace/OS.i (mutex_init): Removed the call to - pthread_mutexattr_setkind_np() it isn't in the final POSIX - standard. - - * ace/Reactor.cpp (unbind): Removed the ACE_MAX3 template function - from OS.h and inlined its only use in the Reactor. This was - causing problems with some C++ compilers. Thanks to Mark Zusman - <marklz@topaz.technion.ac.il> for reporting this. - - * ace/OS.i: Fixed a number of omitted return results in - gettimeofday() and ctime_r() that were masked by the - ACE_OSCALL_RETURN macros. Thanks to Mark Zusman - <marklz@topaz.technion.ac.il> for reporting these. - - * ace/config-linux.h: Added new symbolic constants to handle the - fact that Linux seems to lack recvmsg(), sendmsg(), msync(), and - madvise(). Thanks to Neil Cohen for noticing this. - - * include/makeinclude: Fixed all the *-orbix.GNU files to use - $(ORBIX_ROOT)/lib rather than $(ORBIX_ROOT)/ace. Thanks to - Pramod Kumar Singh <pramod@saturn.miel.mot.com> for reporting - this. - - * ace/config*.h: Changed all typos of the form ACE_HAS_SVSV_IPC to - ACE_HAS_SYSV_IPC. Thanks to Alexandre Karev - <akg@na47sun05.cern.ch> for reporting this! - - * ace/OS: Changed the order of parameters passed to thr_create() - to be consistent with all the spawn() and spawn_n() usages in - ACE. Thanks to Chris Lahey for pointing this out. - -Sun Jan 21 15:06:15 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Added a new "priority" parameter to the spawn() and - spawn_n() methods in ACE_Thread and ACE_Thread_Manager. This - allows us to pass the priority on down to thr_create(). Thanks - to Chris Lahey for pointing this out. Note that this change - required reordering the parameters so that the stack and - stack_size parameters now come last for these methods. Since - those are not likely to change much this is a good place to put - them (i.e., at the end). - - * ace/Thread.i (spawn_n): Added a new overloaded spawn_n() method - that accepts an array of thread_t's to be filled in. This is - useful if you want to know the thread IDs of any threads - created. - - * Changed ACE_OS::signal() to ACE_Sig_Action across all of ACE to - be portable to pthreads implementations. Thanks to Chris Lahey - for pointing this out. - - * ace/OS: Added a new set of OS C++ wrappers for POSIX pthread - cancellation routines. Thanks to Chris Lahey for these. - - * ace/Thread: Added a new set of ACE C++ wrappers for POSIX - pthread cancellation routines. Thanks to Chris Lahey for - these. - - * ace/Map_Manager: Revised the Map_Manager::bind method. This has - now been split into bind() and rebind() methods. The bind() - method is very simple -- if you try to bind() to something that - already exists you fail. The rebind() method allows you to - atomically update existing values in a map. It also gives you - back the existing values so that you can delete them if - necessary. The Local_Name_Space::bind() and rebind() methods - have been updated to use this new interface. - - * ace/Malloc_T.cpp (find): Fixed a typo -- find() should have set - its pointer parameter to node->pointer_, rather than - node->name_! This bug was revealed during testing of the ACE - Name Server. - - * ace/Local_Name_Space.cpp: Fixed bugs with computation of the - size of ACE_NS_Strings -- they needed to count the wchar_t's - correctly, along with several other minor fixes. These were - revealed during testing of the ACE Name Server. - - * ace/SString.cpp: Fixed several bugs that prevented the - assignment operators from working correctly. These were - revealed during testing of the ACE Name Server. - -Sat Jan 20 08:33:54 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Local_Name_Space.cpp (shared_bind): The args to to the - NS_String constructors were not in the correct order: - - wchar_t *value_rep = (wchar_t *) (ptr); - wchar_t *name_rep = (wchar_t *) (ptr + name_len); - ACE_NS_String ext_id (name.fast_rep (), name_rep, name_len); - ACE_NS_String int_id (value.fast_rep (), value_rep, value_len); - - They should be: - - ACE_NS_String ext_id (name_rep, name.fast_rep (), name_len); - ACE_NS_String int_id (value_rep, value.fast_rep (), value_len); - - Thanks to Irfan for noticing this. - - * ace/OS.h: defined the following in ACE_OS: - - #define MS_ASYNC 0 - #define MS_SYNC 0 - #define MS_INVALIDATE 0 - - under NT so that calls to mmap will port transparently. Thanks - to Irfan for suggesting this. - -Thu Jan 18 16:25:16 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Added a new symbol that indicates if the platform supports - the new BSD sin_len field of inet_addr. - - * ace/OS: added new support for AIX gethostbyaddr_r(), - gethostbyname_r(), and getservbyname_r(). This fixes some - problems caused by improper choice of buffer size. Also changed - the INET_Addr.cpp file to use these new changes. Thanks to - Chris Lahey for recommending these changes. - -Wed Jan 17 01:10:48 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.i (printf): the ACE_OS::printf() function did not work. - Needed to call vprintf() internally, not printf. Thanks to - Chris Lahey for pointing this out. - - * Released version 4.0. - - * include/makeinclude: added the -lgen library to all the - platform_sunos5.*.GNU files. - - * ace/Memory_Pool.cpp: removed the INLINE macros in Memory_Pool.cpp. - Thanks to Alexandre Karev (karev@vxcern.cern.ch) for noticing - this! - - * ace/Malloc_T.cpp: moved the comment "Ce n'est pas une catst" - outside of the macro ACE_NEW_RETURN. The prepocessor truncates - the macro expansion when it encounters the comment. Thanks to - Greg Baker <GBaker@p01.az15m.iac.honeywell.com> for pointing - this out. - - * ace/Reactor.cpp (close): added "return 0" at the end of the - close member function. The function is prototyped to return an - int and the compiler expects a return outside of the if clause. - Thanks to Greg Baker <GBaker@p01.az15m.iac.honeywell.com> for - pointing this out. - - * ace/Stack.cpp (free_all_nodes): Removed a spurious ACE_OS that - was stuck on the front of ::delete. Thanks to Greg Baker - <GBaker@p01.az15m.iac.honeywell.com> for pointing this out. - - * ace/OS.i: Added extern "C" to the prototype for syscall in OS.i. - Without it, you get unresolved symbols at link time. Thanks to - Greg Baker <GBaker@p01.az15m.iac.honeywell.com> for pointing - this out. - - * ace/Message_Queue.cpp: Changed the return values for - enqueue_head(), enqueue_tail(), dequeue_head(), and - peek_dequeue_head() to return the number of messages that are - still on the queue. This helps some algorithms perform better - and avoid blocking unnecessarily. Thanks to Alex V Maclinvosky - <alexm@teltrunk1.tait.co.nz> for suggesting this... - - * ace/Synch_T.cpp (ACE_Condition): Fixed a bug in - ~ACE_Recursive_Lock and ~ACE_Recursive_Mutex that was causing - the destructor to be called twice (once implicitly and once - explicitly). Thanks to Chris Lahey for pointing this out. - -Mon Jan 15 12:44:29 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Created a new config symbol called ACE_HAS_ALLOCA_H. This - is required to differentiate between AIX and other versions of - UNIX. Thanks to Chris Lahey for pointing this out. - - * ace: moved config-hpux.h to config-hpux-9.x.h in anticipation of - the changes required to handle HP/UX 10.0! - -Sun Jan 14 23:38:23 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.h (ACE_MAX3): Fixed the definition of ACE_MAX3 (it needed - a return value of template type T). Thanks to Mark Zusman - <marklz@topaz.technion.ac.il> for noticing this. - - * ace: Added a new section to all the template files called - ACE_TEMPLATES_REQUIRE_SPECIALIZATION to deal with the screwy GNU - G++ semantics that are required if you *don't* have the template - repository patches. Thanks to Mark Zusman - <marklz@topaz.technion.ac.il> for this. - -Fri Jan 12 00:47:57 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Time_Value.h: #included <pthreads.h> to the Time_Value.h - class so that it would be the first file included. This fixes a - problem with AIX. Thanks to Chris Lahey for reporting this and - suggesting the fix. - - * ace: Fixed a braino with the #ifdefs in SPIPE_Stream and - SPIPE_Acceptor. These were checking for ACE_WIN32 rather than - ACE_HAS_STREAM_PIPES. Naturally, that failed on versions of - UNIX (e.g., Linux) that lack STREAM pipes! Thanks to Neil Cohen - for taking time out of fighting blizzards to report this! - - * ace/Svc_Handler: Added a new method for handle_timeout, which - shuts things down by default. Thanks to Irfan for suggesting - this. - - * Fixed a minor problem caused when Tim added the Double-Check - pattern to ACE_ODB... - -Thu Jan 11 01:48:02 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Integrated AIX fixes from Chris Lahey <clahey@ix.netcom.com>. - These should allow ACE to build correctly using the AIX compiler - and it's screwy template mechanisms! - - * ace: Fixed some minor bugs that caused problems when compiling - with G++. - -Wed Jan 10 00:17:05 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Trace.cpp: Fixed a typo that was causing problems when using - ACE_TRACE (we were ending up with recursive tracing in the - ACE_Trace class!). Thanks to Detlef for noticing this. - - * ace/ACE.cpp: Moved methods from ACE.i to ACE.cpp and removed the - INLINE macro to deal with order of include problems with GNU - G++. - -Tue Jan 9 19:00:41 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Task.i (flush): Added a check to make sure that msg_queue_ - != 0 before trying to close() the queue. This solves a problem - if the queue has already been closed. Thanks to Alex V - Maclinvosky <alexm@teltrunk1.tait.co.nz> for reporting this... - - * tests/ASX/Event_Server/Event_Server: Fixed minor bugs in - Supplier_Router.cpp and Consumer_Router.cpp -- I was checking - for this->getq (mb) > 0 rather than this->getq (mb) >= 0. - Thanks to Alex V Maclinvosky <alexm@teltrunk1.tait.co.nz> for - noticing this... - - * ace/Synch_T.h: Commented out the ACE_ALLOC_HOOK stuff. This is - causing order-of-include problems on HP/UX. Also moved the - ACE_Null_Condition::wait() method to Synch_T.i to avoid the same - problem. Thanks to Greg Baker - <GBaker@p01.az15m.iac.honeywell.com> for pointing this out. - -Sun Jan 7 18:57:49 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Makefile: Added the Dump file to ACE. Thanks to Tim for - fixing this up to make it ready for prime time. - - * Thanks to Craig Rodrigues <rodrigc@ecf.toronto.edu> for sending - me a new version of psnup that *finally* fixes the nasty - problems with "4-up" printing of postscript! This makes it much - easier to distribute ACE documentation... - -Sun Jan 7 18:31:07 1996 Tim H. Harrison (harrison@merengue.cs.wustl.edu) - - * ace: Used the "Double-Check" pattern to eliminate potential race - conditions when using Singletons in multi-threaded programs. - Classes affected included ACE_[MS]T_CORBA_Handler, Name_Options, - Trace, and ACE_ODB. - -Fri Jan 5 00:03:29 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.i: Added the following to OS.i: - - #if defined (ACE_LACKS_SYSCALL) - int syscall (int, ACE_HANDLE, struct rusage *); - #endif /* ACE_LACKS_SYSCALL */ - - This should fix some problems with HP/UX. Thanks to Walt Akers - (akers@cebaf.gov) for pointing out the problem. - - * ace/Handle_Set: Fixed the Handle_Set conversion operator so that - it returns fd_set * rather than ACE_FD_SET_TYPE *. Thanks to - Walt Akers (akers@cebaf.gov) for pointing out the problem. - - * ace/Time_Value.h: I think I've fixed the problem with the order - of #includes with respect to POSIX and SVR4 time. The trick was - to put this test in ace/Time_Value.h and then to make sure that - the ace/config.h file was included at this point! Also changed - the symbol from ACE_HAS_POSIX_TIMERS to ACE_HAS_POSIX_TIME to be - more accurate. - -Thu Jan 4 23:16:59 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.i (gettimeofday): Changed the implementation of - gettimeofday() to use the ::_ftime call rather than the more - complex ::GetSystemTime(), ::SystemTimeToFileTime() duo. - -Thu Jan 4 9:32:38 1996 Chris Lahey (clahey@ix.netcom.com) - - * ace/config-aix.h: added #define ACE_TEMPLATES_REQUIRE_SOURCE - to make ACE work with AIX C++ compiler. - - * include/makeinclude/platform_aix.GNU: - - Added -qtempinc to the CPPFLAGS - Removed the PIC= definition completely - - * ace/Task.h: ACE_Task::svc() should not be declared as a pure - virtual, removed = 0. - - * ace/Map_Manager.cpp: in trybind() member function, the line - int_id = ss.int_id_; - should be: - int_id = search_structure[index].int_id_; - -Thu Jan 4 01:23:38 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Map_Manager.cpp: Fixed a braino in Map_Manager -- didn't - need the <index> parameter to shared_bind(). Thanks to Tim for - finding this! - - * ace/Log_Msg.cpp (instance): Tim Harrison did a noble service to - humanity by fixing a potential race condition in the instance() - Singleton of ACE_Log_Msg. - -Wed Jan 3 00:49:57 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Made some minor changes to fix portability problems with - SGI. Fortunately, this should also fix some other problems with - HP/UX another other non-thread platforms. - - * ace/ACE.cpp (format_hexdump): Added Todd Montgomery's amazing - "format_hexdump" method to class ACE. - -Tue Jan 2 20:47:57 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/SV_Semaphore*: updated the interface of the _Simple and - _Complex System V semaphore wrappers to include the _read() and - _write() forms of acquire() and tryacquire(). Note that I've - implemented these as calls to acquire() and tryacquire(), so - they don't add any extra behavior. This is needed for interface - conformance with other forms of ACE synchronization mechanisms. - - * ace/Time_Value.h: Changed the header to #include <sys/time.h> - in order to work around nasty "order of include" problems. - - * tests: Created a new directory called Win32. This contains test - programs that This directory contains test programs that have - been compiled and tested successfully under Windows NT. As we - get further along, we'll move this stuff into the general ACE - $WRAPPER_ROOT/tests directory (since of course all ACE programs - will run without any problems under Win32, right? ;-)). See - the ./tests/Win32/README file for instructions on how to build - these tests. - - * ace/Reactor.h: Moved the ACE_Handler_Repository out of the - ACE_MT_SAFE section of the code. This was a "typo." Thanks to - Walt Akers <akers@cebaf.gov> for reporting this. - -Mon Jan 1 01:18:12 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/ACE.i: Moved the recv_n() and send_n() methods from ACE.cpp - into ACE.i and set things so that if __INLINE__ is set then - we'll inline those too! - - * ace: Irfan and I got the first major part of the Win32 to work - finally! We made two socket programs (client and server) that - talked to each other and to UNIX. Things are really starting to - take shape! |
