Harrison <harrison@lambada.cs.wustl.edu> - - * ace/Token_Invariants.cpp: Moved static data - declarations out of ACE_Token_Invariant_Manager::instance and - into the header file. This is supposed to help with a g++ - problem on VxWorks. - -Sun Nov 10 13:22:03 1996 Douglas C.

Thanks to Luca - Priorelli <lucapri@mbox.vol.it>. - - * ace/Thread_Manager: Created a new version of spawn_n() that - gives parameters for stack, stack_size, and also for the - assigned ACE_hthread_t's. Thanks to Thilo Kielmann - <kielmann@informatik.uni-siegen.de> for suggesting this. - -Sat Nov 9 11:23:13 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Synch.i: Fixed a bug in ACE_Thread_Mutex_Guard. - The call: - - this->owner_ == block ? this->lock_.acquire () : this->lock_.tryacquire (); - - should be - - this->owner_ = block ? this->lock_.acquire () : this->lock_.tryacquire (); - - Thanks to Alexander Smundak <sasha@migration.com> for reporting - this. - -Fri Nov 8 20:04:26 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Malloc.h: Fixed a typo on line 176 that reads: - - #include "ace/Sync_T.h" - - It should read: - - #include "ace/Synch_T.h" - - Thanks to Todd Barkalow <todd_barkalow@stortek.com> for - reporting this. - -Wed Nov 6 00:38:02 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Pipe: Added the const qualifier to the following methods: - - ACE_HANDLE ACE_Pipe::read_handle (void) const; - ACE_HANDLE ACE_Pipe::write_handle (void) const; - - Thanks to Luca for reporting this. - - * ace/config-win32-msvc4.0.h: Redefined - ACE_LACKS_STATIC_DATA_MEMBER_TEMPLATES since it looks like - MSVC++ 4.0 still doesn't work. Maybe this is fixed in 4.2? - -Tue Nov 5 03:09:44 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Strategies.cpp: I'd forgotten to update one of the - accept(*svc_handler) calls to use the new - accept(svc_handler->peer()) syntax. - - * netsvcs/lib/Server_Logging_Handler.cpp: Added a cast to - (COUNTER) 0 when initializing ::request_count_ to avoid problems - on Win32. Thanks to Luca for pointing this out. - - * ace/Thread_Manager: Added a new thr_self() method that return - the unique ID of the thread. This is not strictly necessary - (because a thread can always just call <ACE_Thread::thr_self>). - However, we put it here to be complete. Thanks to Hamutal Yanay - <Hamutal_Yanay@mail.icomverse.com> for suggesting this. - - * ace/OS.cpp (thr_create): I was accidentally closing down - ::CloseHandle (thr_handle) (where thr_handle is a HANDLE *) when - I should have been doing a ::CloseHandle (handle) instead. - Thanks to Luca for finding this! - -Sat Nov 9 01:44:15 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu> - - * ace/Message_Queue: Added forward and reverse iterators to - Message_Queue. Also, added typedefs to Message_Queue for - ITERATOR, and REVERSE_ITERATOR. This makes the Queue like an STL - collection and also makes it easier to use since you don't have - to define types for the iterators. Please see - test/Message_Queue_Test.cpp for an example. - - * ace/Map_Manager: Added reverse iterator to Map_Manager. Also, - added typedefs to Map_Manager for ENTRY, ITERATOR, and - REVERSE_ITERATOR. This makes the Map more like an STL collection - and also makes it easier to use since you don't have to define - types for the iterators and the entry. Please see - test/Map_Manager_Test.cpp for an example. Note that the new - typedefs does not break existing code. - -Tue Nov 5 14:26:32 1996 David Levine <levine@cs.wustl.edu> - * include/makeinclude/wrapper_macros.GNU: Changed LINK.{c,cc} - commands to use LD instead of CXX. Changed all platform macros - files (except for g++ on VxWorks) to correspond. - - * tests/run_tests.sh: changed -e test to -f for portability and - reordered tests. Thanks to Michael Michael Rueger - <m_rueger@SYSCOMP.DE> for originally creating run_tests.sh, and - for maintaining it, and to Alan Stewart <axs2@osi.com> for - suggesting fixes/enhancements. - - * tests/Time_Service_Test.cpp and Tokens_Test.cpp: changed to - return 0 on success instead of 42 - -Fri Nov 1 03:53:39 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu> - - * STL: Added STL files to $WRAPPER_ROOT/STL. This code is a - modified version (changes for VC++ compiler) of the publicly - available implementation of STL from HP. Currently, - ACE_Registry uses these STL classes. - -Fri Nov 1 00:25:01 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/CORBA_Handler.cpp (process_events): There was a very subtle - race condition in the ACE_MT_CORBA_Handler. process_events() - accessed the singleton directly without taking the mutex. At - startup the process_event thread is kicked off from the - constructor and the instance_ is set. Hence the race. The - solution is to attempt to take the mutex before accessing the - instance. Thanks to David Artus <david.artus@sbil.co.uk> for - reporting the problem and providing the fix. - - * ace/Log_Msg.cpp (log): Improved the performance of the Log_Msg - mechanism by not doing any parsing of the format string if the - user has disabled this priority. - - * ace/Reactor.cpp: Added a chance for the open() method of the - Notification_Pipe failing. Thanks to Luca for pointing this - out. - - * ace/Reactor.cpp (handle_events): Added a change to the semantics - of the ACE_Reactor so that it doesn't fall out of the event loop - when signals arrive that it handles. Thanks to Stuart Powell - <stuartp@in.ot.com.au> for this fix. - - * ace/Service_Repository.cpp (remove): Fixed a bug with - Service_Record::remove() that was failing if there were only two - records and we are removing the first one. Thanks to Alex - Villazon <villazon@cui.unige.ch> for reporting this. - - * ace: Recompiled everything on Solaris with G++ and CC and it - seems to work fine. - - * ace/Module: Replaced the use of char * with const char * for - assigning the Module a name. - - * ace: Split the Task.{cpp,i.h} file into Task_T.{cpp,i,h} in - order to factor out the new non-template ACE_Task_Base and - ACE_Task_Exit classes. This is required for GCC-based compilers - that include the *.cpp files... - -Thu Oct 31 00:36:38 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Malloc_T.h: Made the destructor of ACE_Allocator_Adapter - virtual. - - * ace/Thread: Reorganized the ACE_Thread so that the - ACE_HAS_THREADS #ifdef is no longer required... - - * ace/Strategies.h: Changed all the destructors to be virtual so - that G++ will stop complaining... - - * ace/Thread_Manager: Reorganized the ACE_Thread_Manager so that - the ACE_HAS_THREADS #ifdef is no longer required... - - * ace/config-win32-msvc4.0.h: Added Dieter Quehl's great hack to - get ACE to compile correctly on Win32 with MFC! - - * ace/Task: I've rearranged the implementation of ACE_Task<> - in the following way: - - 1. Defined a non-template class ACE_Task_Base from which the - ACE_Task<...> inherits (instead of inheriting from - Ace_Service_Object, which ACE_Task_Base now inherits from. - - 2. Move all methods that don't depend on the <ACE_MT_SYNCH> or - <ACE_NULL_SYNCH> modifers from the ACE_Task template to - ACE_Task_Base. - - There are two motivations for making this change: - - 1. It reduces ``template bloat'' by factoring out common - code that can be shared between ACE_Task<ACE_MT_SYNCH> - and ACE_Task<ACE_NULL_SYNCH>. - - 2. It makes it possible for the Thread_Manager to use - ACE_Task_Base *'s for managing groups of ACE_Tasks - in a fully polymorphic manner. - - Note that the new changes don't break any existing code that - uses ACE_Task. Thanks to Hamutal Yanay - <Hamutal_Yanay@hub.comverse.com> and Ari Erev's - <Ari_Erev@comverse.com> for suggesting these changes. - - * ace/Thread_Manager: Changed the use of ACE_Task<ACE_SYNCH> to - ACE_Service_Object because this avoids nasty problems with - template type conflicts. The right solution is probably to - create a new non-template base class for ACE_Task called - ACE_Task_Base and move all the ACE_Task operations into there - that don't involve the Message_Queue directly. I'll need to - think more about this... - - * ace/SOCK_Stream: Added new timed send_n() and recv_n() methods, - which use the underlying timed ACE::send() and ACE::recv() - calls. - - * ace/ACE.cpp: Added new timed send_n() and recv_n() methods, - which use the underlying timed ACE::send() and ACE::recv() - calls. - -Wed Oct 30 00:27:21 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/OS.h: Changed MAXHOSTNAMELEN on Win32 from - (MAX_COMPUTERNAME_LENGTH+1) (which is around 16 or so) to 256. - Thanks to Tilo Christ <christ@swl.fh-heilbronn.de> for this - suggestion. - - * ace: Made #define STRICT a compile time option if the - ACE_HAS_STRICT flag is enabled. This prevents ACE from breaking - existing application (i.e., non-ACE) code. Thanks to Karlheinz - for pointing this out! - - * ace/Synch_T.cpp: Fixed a typo in ACE_Condition<MUTEX>::wait - (void). - - return ACE_OS::cond_wait (&this->cond_, this->mutex_.lock_); - - should read - - return ACE_OS::cond_wait (&this->cond_, &this->mutex_.lock_); - - Thanks to Dieter Quehl <dietrich.quehl@med.siemens.de> for - reporting this! - - * ace/Svc_Handler.h: Removed the operator ACE_PEER_STREAM &() from - the ACE_Svc_Handler class since we don't need it anymore due to - the changes below. - - * ace/{Acceptor,Connector}.cpp: Removed the use of operator - ACE_PEER_STREAM &() in the Acceptor::accept() and - Connector::connect() code and replaced it with - svc_handler->peer(). This works much better and is more - intuitive. - -Wed Oct 30 00:30:00 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu> - - * Registry: Added a Name Service implementation to ACE based on - Win32 Registry. The ACE_Registry interface is inspired by the - interface specified in the CORBA Naming Service Specification. - The implementation is done through Win32 Reg*() functions. - Other than providing an OO wrapper for the Win32 Reg*() - functions, ACE_Registry provides an abstraction for iteration - over the elements of the Registry. This only works on Win32 - platforms (unless you are brave enough to reimplement the - Win32 Registry API on UNIX and link it in underneath ACE!). - - * ace/Local_Name_Space_T.cpp: Moved SEH out of methods of - Name_Space_Map to the methods of Local_Name_Space. Some of - the calls to Local_Name_Space methods used the allocator to - either malloc or find or free shared memory. Adding SEH to these - methods ensured that any exception raised due to remapping would - be caught and handled appropriately. - - Also, to fool the stupid MFC compiler, we added _i methods - so that it stopped bitching about destructors not getting called - correctly. - - * Added three new tests to /examples/Naming. Thanks to Lothar for - providing these tests. - -Tue Oct 29 18:10:09 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/ACE.cpp (send): Integrated a new and simpler version of - timed ACE::send(). Thanks to Vital Aza <va3@cs.wustl.edu> for - coming up with this. - - * ace/XtReactor.cpp: When the ACE_Reactor is constructed it - creates the notify pipe and registers it with the attach() - method. The XtReactor overloads this method BUT because the - attach occurs when constructing the base class ACE_Reactor, the - ACE_Reactor attach() is called not the XtReactor attach(). This - means that the notify pipe is registered with the ACE_Reactor - event handling code not the XtReactor and so notfications don't - work. To get around this we simply close and re-opened the - notification handler in the constructor of the XtReactor. - Thanks to Rodney Skinner <rods@in.ot.com.au> for this fix. - - * ace/XtReactor.cpp (schedule_timer): The ACE_Reactor returns a - timer_id from it's equivalent call but the XtReactor always - returns 0. To fix this we simply replaced the "return 0;" in - the function with "return result;" Thanks to Rodney Skinner - <rods@in.ot.com.au> for reporting this. - -Tue Oct 29 00:02:44 1996 Douglas C. Schmidt <schmidt@lambada.cs.wustl.edu> - - * ace/config-win32-msvc4.0.h: Defined the STRICT symbol based on a - suggestion from Luca. STRICT type checking in WINDOWS.H - enhances type safety for Windows programs by using distinct - types to represent all the different HANDLES in Windows. So for - example, STRICT prevents you from mistakenly passing an HPEN to - a routine expecting an HBITMAP. Note that if you have STRICT - type checking enabled in one file, but not in another, the C++ - compiler will generate different external link symbols for a - single function. This will result in link-time errors If you are - mixing STRICT and non-STRICT code, you must be aware of linkage - inconsistencies. In general, all MFC programming and all C++ - should be done with STRICT. If you have legacy C code, then not - using STRICT is acceptable - - * ace/OS.cpp (thr_create): Added a special check for the situation - where we have both ACE_HAS_PTHREADS and ACE_HAS_STHREADS - defined. In this case, we are running on Solaris, where - ACE_thread_t and ACE_hthread_t are the same. Therefore, we can - copy the value of the *thr_id into the *thr_handle. This - ensures that the ACE_Thread_Manager behaves correctly with - respect to suspending and resuming threads and ACE_Tasks. - - * ace/Trace.cpp (ACE_Trace): Changed the use of LM_DEBUG to - LM_TRACE in the constructor and destructor. Thanks to Luca for - this! - - * ace/OS.i: Added a cast to of (HMODULE) handle so that the STRICT - macro would work correctly for Win32. Thanks to Luca for this. - - * ace/config-win32-msvc4.0.h: According to Luca, ACE compiles file - with ACE_LACKS_STATIC_DATA_MEMBER_TEMPLATES undefined on NT. So - I undefined it! If there are any problems with this, please let - me know. - - * ace/SOCK_Dgram: Added Luca Priorelli <lucapri@mbox.vol.it> - implementation of recv() for SOCK Dgrams that allows clients to - read from a socket without having to provide a buffer to read. - - * examples/Threads/test_task_four.cpp: This is a new test - program to test the new interfaces. Thanks to Hamutal Yanay - & Ari Erev for this. - - * tests/test_config.h: Added a call to the new ACE_OS::mkdir() - wrapper to create the log directory if one doesn't already - exist. This should solve some nasty problems with NT reported - by Tilo Christ <christ@swl.fh-heilbronn.de>. - - * ace/OS.h: Added a new macro ACE_DEFAULT_DIR_PERMS and changed - the spelling of the existing ACE_DEFAULT_PERMS to - ACE_DEFAULT_FILE_PERMS, which is more accurate. - -Mon Oct 28 21:35:12 1996 Douglas C. Schmidt <schmidt@lambada.cs.wustl.edu> - - * ace/OS.h: Added a wrapper for the mkdir() system call. We need - it for some of the tests. - - * ace/Task: Changed the name of ACE_Task_Exit<>::set_this() to - ACE_Task_Exit<>::set_task(). Thanks to Hamutal Yanay & Ari Erev - for suggesting this. - - * ace/{Task,Thread_Manager}: Integrated Hamutal - <Hamutal_Yanay@hub.comverse.com> Yanay & Ari Erev's - <Ari_Erev@comverse.com> enhancements to add ACE_Task support - to the ACE_Thread_Manager. This allows the ACE_Thread_Manager to - know about ACE_Tasks directly, rather than knowing - indirectly via their lower-level thread IDs. The changes - are described below: - - - Added a parameter to the activate() method. It is used to - pass an ACE_Task* to spawn_n(). - - - Modified suspend() and resume() to call - thrMgr->suspend_task() and thrMgr->resume_task() instead of - thrMgr->suspend_grp() and thrMgr->resume_grp(). - - - Added an ACE_Task * parameter to spawn_n(). - - - Added an ACE_Task * parameter to append_thr(). - - - append_thr() uses the ACE_Task * input parameter to - initialize the thread descriptor. - - - Added the following methods: - apply_task() - suspend_task() - resume_task() - kill_task() - resume_task() - cancel_task() - find_task() - - num_tasks_in_group() - num_threads_in_tasks() - - task_list() - thread_list() - hthread_list() - - set_grp() Like the current set_grp() but gets an ACE_Task * - as input. - get_grp() Like the current set_grp() but outputs an - ACE_Task *. - - wait_task() - wait_group() - -Sun Oct 27 11:25:00 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/OS: modified the ACE_OSCALL_RETURN macro so that we'll - no longer have zillions of warnings about _result not - used... - - * ace/Synch_T: Changed the use of ACE_Mutex for ACE_TSS to - ACE_Thread_Mutex. - - * ace: Added the necessary template specializations to get ACE - compiled correctly with G++. - - * ace/Log_Msg.h: There were some places in the ACE_{DEBUG,ERROR} - macros that should have been using __ace_error but there still - using errno (which is wrong since this might be changed due to - side-effects of calling ACE_Log_Msg::instance()). I found this - problem due to the use of -Wall with G++! As a result of this - fix, ACE now compiles much more cleanly with gcc -Wall. - - * ace/Strategy: Improved the scheme used to define the PEER_ADDR - type of the ACE_Accept_Strategy so that it will work correctly - on platforms whose C++ compilers aren't quite up to handling all - variants of template typedefs. In particular, many platforms - don't support the use of template typedefs in parameter names... - - * ace/OS: HP/UX omitted the const in the prototype of - const_timewait(). Therefore, I added a new typedef to handle - this and updated all the HP/UX config*.h files. - - * ace: Added a new config file (config-sunos5.5-sunc++-4.1.h) - which reflects the fact that SunC++ 4.1 fixes template bugs that - prevented earlier versions from supporting template typedefs - correctly. The new config file #defines - ACE_HAS_TEMPLATE_TYPEDEFS. - -Sat Oct 26 02:22:25 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace: On the advice of David Levine, I compiled ACE with gcc - -Wall and started to fix lots of minor warnings (e.g., - misordered data member initializations). - - * ace/Local_Tokens.h: Changed the destructors of ACE_Mutex_Token, - ACE_RW_Token, ACE_Token_Proxy, and ACE_RW_Token to be virtual. - - * ace/Synch_T.h: Changed the destructor of ACE_TSS to be virtual. - - * ace/OS: Changed the prototype of ACE_OS::select() so that it - uses const ACE_Time_Value *. - - * Updated all uses of ACE_Malloc to use the new ACE_*_MEMORY_POOL - #defines. This makes it possible to use the ACE_Malloc<> scheme - with lame C++ compilers. - - * ace/ACE: Changed the interface of the new timed send/recv calls - to use ACE_Time_Value *, which makes it easier to determine - the blocking semantics at runtime. Thanks to Bill Fulton - <bill@fasttrack2.bscc.bls.com> for suggesting this. - -Sat Oct 26 15:55:02 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu> - - * ace/OS.h: We determined that MSVC++ is capable of supporting - template typedefs. Therefore, we can enable the - ACE_HAS_TEMPLATE_TYPEDEFS flag, which makes life much easier for - end users! - -Fri Oct 25 23:16:16 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu> - - * examples/Shared_Malloc/test_multiple_mallocs.cpp: Added a new - test that demonstrates the new ability of ACE_Malloc<> to to - handle multiple mallocs rooted at different base addresses. - - * ace/Memory_Pool: Fixed this stuff so that it works even when C++ - compilers can't grok template typedefs. - - * ace: Put all the macros that handle the fact that many C++ - compilers have broken template implementations into one place - (OS.h), rather than having this spread out in many files. - - * In ACE_MMAP_Memory_Pool::init_acquire (), we reset errno to 0 in - the case where the file already exists (and errno == EEXIST). - - * Added an ACE_*_Memory_Pool_Options class to each Memory Pool - class. The Options class allows detailed parameters to be passed - to the constructor of the Memory Pool class. Since a typedef'd - Options class was added to every Memory Pool class, this gave us - the ability to use traits in ACE_Malloc and - ACE_Allocator_Adapter to construct generic Memory Pools that can - be initialized uniquely for each instance of ACE_Malloc. Note - that this new feature only works for C++ compilers that support - template typedefs correctly (e.g., MSVC++ 4.x, SunC++ 4.1, - and the AIX C++ compiler). - - * Added additional constructors to ACE_Malloc and - ACE_Allocator_Adapter to allow Options to be passed in to Memory - Pool. - - * Added an extra field in ACE_Name_Options which allows - specification of the base address of the memory pool. This is - now used by ACE_Local_Name_Space::create_manager() to create an - ACE_Allocator_Adapter. This now allows us to have multiple - ACE_Naming_Context simultaneously in the same process address - space. - - * Also added error checking for constructors (in - ACE_Local_Name_Space and ACE_Malloc) by checking errno - values. This is a "hack" since we currently do not use exception - handling. - -Thu Oct 24 02:43:11 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * examples/Connection/misc/Makefile: The Makefile in - ACE_wrappers/examples/Connection/misc seems to have been - truncated. I replaced it. Thanks to Alan Stewart - <axs2@osi.com> for reporting this. - - * examples/IPC_SAP/SOCK_SAP/CPP-{inclient,inserver}.cpp: Updated - these examples to use the new timed send()/recv() operations. - - * ace/SOCK_IO: Added timed send()/recv() methods, using the base - level implementations in class ACE. - - * ace/ACE: Added timed send()/recv() methods. - -Wed Oct 23 19:56:45 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * examples/IPC_SAP/SOCK_SAP/CPP-inclient.cpp (main): Changed the - behavior of the test program so that it doesn't take a - local_addr, but rather will use the default (this prevents a - common problem that happens when users run the test without - reading the README file). - - * ace/ACE.cpp: Added a new method (get_flags) that returns the - current setting of flags associated with handle. - - * Start of a brave new world: ACE is now under CVS version - control... Thanks to David Levine and Chris Cleeland - for making this happen. - -Sat Oct 19 12:33:56 1996 David L. Levine <levine@cs.wustl.edu> - - * added ACE threads mappings to VxWorks 5.2 tasks in OS.*. - NOTE: this is _untested_ at this point, but only affects - VxWorks code - - * changed name of first argument of ACE_OS::sigprocmask() and - ACE_OS::thr_sigsetmask() from "signum" to "how" to better - represent what it really is. - -Wed Oct 16 01:59:40 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Log_Record.cpp (print): added Luca's suggestion for checking - if host_name == 0 for the ostream version of print(), as well. - - * Released version of ACE 4.0.32 for testing. - - * ace/Synch.h: Added many small fixes for HP/UX 10.x. Thanks to - Alan Stewart <axs2@osi.com> for providing these. - - * ace/OS.h: Added many new ACE_LACKS* and ACE_HAS* macros to - support the MVS port. Thanks to Chuck Gehr - <gehr@sweng.stortek.com> for these. - -Tue Oct 15 11:56:59 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/OS.h: in a continuing effort to protect the ACE namespace, - I've changed ace/OS.h around lines 127-137 so that "SYNCH" and - "SYNCH_MUTEX", etc. are prefixed with "ACE_". Thanks to Alan - Stewart <axs2@osi.com> for suggesting this. - - * ace/Local_Tokens.h: Removed an unnecessary parameter name - that was unused. Thanks to Stuart Powell <stuartp@in.ot.com.au> - for reporting this. - -Tue Oct 15 17:03:37 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu> - - * ace/ReactorEx.cpp (handle_events): Fixed a bug in handle_events - so that the correct handlers get called when multiple handles - become signaled simultaneously. Thanks to Ari Erev - <Ari_Erev@comverse.com> for pointing out this bug. I also took - this opportunity to fix a bug when handlers are removed during - handle_events. - - * examples/Reactor/ReactorEx/test_remove_handler.cpp: Added a new - application that tests how the ReactorEx services simultaneous - events and removes handlers. This example also illustrates the - use of the new ACE_Events wrapper. Check - examples/Reactor/ReactorEx/README for more details. - -Mon Oct 14 11:43:18 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * tests: Added a new version of run_tests.sh, which was - contributed by Michael Rueger <mike@SYSCOMP.DE>. - - * examples/Logger/simple-server/Logging_Handler.cpp (handle_input) - and examples/Logger/Acceptor-server/server_loggerd.cpp - (handle_input): Changed from stderr to cerr to work around bugs - with the C run-time libraries on Win32. Thanks to Tilo Christ - <christ@swl.fh-heilbronn.de> for suggesting this. - -Mon Oct 14 11:09:42 1996 Prashant Jain <pjain@merengue.cs.wustl.edu> - - * ace/Local_Name_Space_T.cpp (remap): Added processor specific - stuff to remap(). The code was taken from the book "Win32 - Network Programming" by Ralph Davis (p.18) and takes care of - cases specific to the 80x86 processor. The code ensures that the - registers are set properly when we continue execution after an - exception. - -Sun Oct 13 21:18:38 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Log_Record.cpp (print): Added a test to make sure that the - value returned from ctime_r != 0 (e.g., if time_stamp_ == -1) in - order to avoid crashes. - - * examples/Logger/client/logging_app.cpp (main): Moved the - construction of the ACE_Log_Record log_record object into the - loop so that it will be recreated each time through. If this - isn't done, then we'll be continually "encoding" values into - network byte order that have already been encoded and screwing - things up on little-endian machines (such as Intel). Thanks to - Irfan and Tilo Christ <christ@swl.fh-heilbronn.de> for pointing - me in the right direction on this. - - * ace/Log_Record.cpp: Changed the default constructor so that it - gives default initializations to the data members. - - * examples/Logger/Acceptor-server/server_loggerd.cpp (handle_input): - Fixed a couple of typos where - - Logging_Handler::handle_input (int) - - should be: - - Logging_Handler::handle_input (ACE_HANDLE) - - and - - size_t len; - - should be: - - ssize_t len; - - Thanks to Irfan for finding these. - -Sat Oct 12 08:48:23 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * Released a beta version of ACE 4.0.32 for testing. - - * ace/Log_Record.cpp: rewrote the code a bit to try and avoid - problems on NT when host_name == 0. - - * ace/Log_Record.cpp: Changed the use of ACE_OS::ctime() to - ACE_OS::ctime_r() to avoid problems that might arise when - ACE_Log_Record::print() is called from multiple threads. - - * ace/Log_Record.cpp: Commented out calls to ACE_TRACE to avoid - weird problems with circular dependencies. Thanks to Luca - Priorelli <lucapri@mbox.vol.it> for suggesting this. - - * build/SunOS5.5/examples/Makefile: Added the Logger directory to - the list of targets that are build automatically by Make. - -Fri Oct 11 17:13:03 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace: Fixed lots of small warnings revealed when using the - Greenhills compiler on VxWorks. Thanks to David Levine for - this. - - * ace/Pipe.h: In Pipe.h, the return value of ACE_Pipe::close() - isn't explicitly declared, so some compilers gag. Thanks to - David Levine for this. - -Thu Oct 10 12:05:55 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Thread.cpp: Correctly wrapped the methods in the *.cpp file - so that they are ignored if threads *aren't* supported. - - * ace/Service_Repository.cpp (remove): Added the ACE_MT in front - of all the ACE_GUARD* macros that utilize ACE_Thread* locks in - order to ensure that ACE compiles correctly on all non-MT - platforms. - - * examples/Shared_Malloc/Malloc.cpp: Removed the special purpose - class for PROCESS_MUTEX since ACE_Process_Mutex will now work - for non-MT platforms. - - * examples/Misc/test_dump.cpp: Changed all occurrences of - - cerr << "string " << this << endl; - - to - - cerr << "string " << (u_long) this << endl; - - to work around problems with IRIX 5.3. Thanks to Tilo Christ - <christ@swl.fh-heilbronn.de> for reporting this. - - * ace/config-linux.h: Added a // in front of a stray comment line. - Thanks to Neil Cohen for pointing this out. - - * ace/config-hpux-10.x-g++.h: Added a new config file for HP/UX - 10.x which should fix some problems with templates by using the - G++ compiler. Thanks to <afarahat@CCGATE.HAC.COM> for - contributing this. - -Wed Oct 9 14:34:19 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/OS: Changed the logic of socket initialization, which has - been moved out of ACE_SOCK and into ACE_OS. This makes it - possible to program more fully at the ACE_OS API (if such a - crazy thing is really necessary ;-)). - - * examples/IPC_SAP/SOCK_SAP/C-in{client,server}.cpp: Fixed up the - client and server apps so they will work on NT - (i.e., replaced the use of int with ACE_HANDLE). Thanks to Joe - DeAngelis <bytor@faxint.com> for suggesting this. - - * ace/Synch.h: Now that we've got support for POSIX semaphores on - Solaris, then we'll use them (when they are supported...) as the - implementation of ACE_Process_Semaphore rather than using the - slower ACE_SV_Semaphore_Complex stuff... - - * ace/OS.{h,i}: Added David Levine's support for named POSIX - semaphores. If ACE_HAS_POSIX_SEM is defined, then ACE_Semaphore - will construct a named POSIX semaphore if passed a non-null - name, or an unamed POSIX semaphore if passed a null name. This - is a great addition because POSIX semaphores are more powerful - and useful than the Solaris UI semaphores. Unfortunately, - Solaris 2.5 doesn't support them (yet). - -Tue Oct 8 16:00:00 1996 Irfan Pyarali <irfan@flamenco.cs.wustl.edu> - - * ace/OS: Integrated Irfan's encapsulation/emulation for Win32 - Events at the ACE_OS level. A new structure ACE_event_t was - created to support Events on non-WIN32 platforms. On WIN32 - platforms ACE_event_t is just a HANDLE. On non-WIN32 platforms, - ACE_event_t uses a combination of mutexes, condition variables, - and counters to emulate Events. Both auto-reset and manual-reset - events are supported. - - * ace/Synch: Integrated Irfan's encapsulation/emulation for Win32 - Events at the C++ wrappers level. There are three wrappers that - were created: ACE_Event, ACE_Auto_Event, and ACE_Manual_Event. - ACE_Event is a wrapper for the ACE_event_t structure. It - provides functionality for signal, wait, pulse, and reset on an - event. ACE_Event supports both auto-reset and manual-reset - events. However, specializations of ACE_Event were created - (ACE_Manual_Event and ACE_Auto_Event) to make it easier to use - Events. - - * examples/Threads/test_manual_event.cpp: A test for manual-reset - events. The test involves the creation and use of a barrier - which uses an ACE_Manual_Event. - - * examples/Threads/test_auto_event.cpp: A test for auto-reset - events. The test involves the use of an ACE_Auto_Event for - signaling threads. - -Tue Oct 8 15:45:01 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/DEV.cpp (ACE_DEV): Removed a stray call to - ACE_IO_SAP::dump(). Thanks to Brad Flood <BFLOOD@tcs.lmco.com> - for this fix. - - * ace/OS.i: Added ACE_HAS_CHARPTR_SOCKOPT for VxWorks. Thanks to - David Levine for this. - - * ace/Dump.cpp (instance): Added an ACE_MT() macro around the - ACE_GUARD_RETURN macro so that this will compile correctly on - non-threaded platforms. Thanks to David Levine for this. - - * ace/OS.h: the declaration of ACE_OS::msgctl needs "struct - msqid_ds" instead of just "msqid_ds" to compile with the - Greenhills C++ compiler. Thanks to David Levine for this... - - * ace/Local_Name_Space_T.h: Added #include "ace/Local_Name_Space.h" - to avoid a problem during template generation. Thanks to - Chris Lahey for this fix. - - * ace/OS.i (getprotobynumber_r): Added a pair of fixes from Chris - Lahey to get the ACE wrappers for the getprotoby*_r() methods to - compile on AIX. - - * examples/Threads: Added two new examples (test_auto_event.cpp - and test_manual_event.cpp) that exercise the new ACE_Event - mechanisms. - - * ace/Synch: Integrated Irfan's encapsulation/emulation for Win32 - Events at the C++ wrappers level. - - * ace/OS: Integrated Irfan's encapsulation/emulation for Win32 - Events at the ACE_OS level. - -Fri Oct 4 08:32:47 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/OS.i: Added David Levine's new ACE_OS::mktemp() implementation. - -Wed Oct 2 13:26:20 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/SV_Message_Queue.i: Changed the casts of (msgbuf *) to - (void *). - - * ace/OS.i: Added David Levine's implementation of inet_addr() for - VxWorks. - - * ace/OS.i: Continued to merge together various parts of Win32 and - UNIX to reduce redundancies. - -Tue Oct 1 15:03:42 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/OS.i: Added Chuck Gehr's new changes to ACE_OS::mutex_init() - and ACE_OS::cond_init() to handle the MVS Pthreads madness. - - * ace/OS.i: Added zillions of #ifdefs for VXWORKS. It's amazing - these guys call themselves POSIX compliant -- lots of stuff is - missing. Thanks to David Levine for doing this! - - * ace/OS.cpp: Added David Levine's implementation of mktemp() - for platforms that don't support it. - - * ace/OS.h: Added a bunch of minor changes for VXWORKS. In - addition, started to factor out common #ifdefs to make the code - easier to maintain. - - * ace/OS.h: Added a new macro for ACE_LACKS_UTSNAME, and factored - this out for both VxWorks and Win32. - - * ace/Time_Value.h: Added support for 2 VXWORKSisms: (1) we need - to #include sys/times.h rather than the standard UNIX sys/time.h - and (2) we need to change const timeval & to const struct - timeval & to keep the Greenhills compiler happy. Thanks to - David Levine for this. - - * ace/INET_Addr.cpp: Added support for the insane VXWORKS - hostGetByName() function. Yikes! Thanks to David Levine for - this. - - * ace/Memory_Pool.cpp: Added a new #define called ACE_LACKS_SBRK - and ACE_LACKS_SYSV_SHMEM, which is enabled on Win32 and VxWorks. - Thanks to David Levine for reporting this. - - * ace/OS.h: Added new macros that #define ETIME for platforms like - VxWorks that don't support it, but do support ETIMEDOUT. - - * ace/OS.h: Added placeholder #defines for USYNC_PROCESS and - USYNC_THREAD when !defined (ACE_HAS_THREADS). Thanks to Neil - Cohen for reporting this. - -Tue Oct 1 00:42:35 1996 Douglas C. Schmidt <schmidt@polka.cs.wustl.edu> - - * ace/Message_Block.cpp (size): Member base_ of ACE_Message_Block - was being set to the new memory pointer before the old contents - are saved in method size. So the line - - this->base_ = buf; - - was moved to a place some lines below. Thanks to Marco Sommerau - <sommerau@informatik.uni-stuttgart.de> for detecting this. - - * ace/Message_Queue.cpp: Changed the implementation of the - enqueue_i() method so that FIFO order is maintained when - messages of the same priority are inserted consecutively. - Thanks to Jay Denkberg <jay_denkberg@comverse.com> for - suggesting this. - -Mon Sep 30 22:59:38 1996 Douglas C. Schmidt <schmidt@polka.cs.wustl.edu> - - * ace/OS.i (thr_yield): Added a new macro ACE_HAS_YIELD_VOID_PTR - to make pthread_yield work on MVS. Thanks to Chuck Gehr - <gehr@sweng.stortek.com> for this fix. - - * ace/OS: Added a new macro called ACE_HAS_TIMEZONE_GETTIMEOFDAY - that handles problems on MVS. Thanks to Chuck Gehr - <gehr@sweng.stortek.com> for this fix. - -Mon Sep 30 13:45:10 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu> - - * ace/Local_Tokens.h: Updated some documentation in all the Token - files. - -Mon Sep 30 18:01:12 1996 Prashant Jain <pjain@merengue.cs.wustl.edu> - - * netsvcs/lib/: Renamed files Logger.{h,cpp} to - Logging_Strategy.{h,cpp} to avoid confusion with Server_Logging - and Client_Logging stuff. In addition, I modified the affected - files, including Makefile, README, and the config files in the - tests directory. - -Sun Sep 29 12:47:37 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/OS.h: Added Chuck Gehr <gehr@sweng.stortek.com> fixes for - MVS to enable signals to work correctly. - - * ace/Time_Value.h: Added an extern "C" { } block around #include - <pthreads.h> to solve a problem with Linux. Thanks to Padhu - Ramalingam <padhu@magicnet.net> for reporting this. - - * netsvcs/lib/Server_Logging_Handler.cpp: Changed the - initialization of a static template object from ::request_count_ - (0L) to ::request_count_ = 0L. Thanks to Gonzalo Diethelm - <gonzo@ing.puc.cl> for reporting this. - - * ace/Remote_Tokens.h: Moved the inclusion of "Singleton.h" from - Remote_Tokens.cpp to Remote_Tokens.h. This should avoid - template instantiation problems on some platforms (e.g., Irix - 6.2). - - * ace/config-irix6.2-sgic++.h: Changed ACE_HAS_SIGINFO to - ACE_HAS_SIGINFO_T and added ACE_HAS_UCONTEXT_T. Thanks to - Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this. - - * ace/Token_Invariants.h: The ctor/dtor were private and the - compiler would not allow a template of the class to be created. - I switched them to public, but I wish there was a better way... - Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting - this. - - * ace/Synch_T.h: #include'd "ace/Event_Handler.h". Thanks to - Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this. - - * ace/Synch.h: The parameter name gives warnings when - instantiating templates. Thanks to Gonzalo Diethelm - <gonzo@ing.puc.cl> for reporting this. - - * ace/Process: Changed the definition of the get_pid() method to - getpid() to avoid a conflict with Irix. Thanks to Gonzalo - Diethelm <gonzo@ing.puc.cl> for reporting this. - - * ace/Log_Msg.cpp (log): Added another #elif !defined (ACE_WIN32) - to handle logging for OS platforms that (1) aren't Win32 and (2) - are versions of UNIX that don't support STREAM pipes. Thanks to - Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this. - - * ace/Acceptor.cpp (handle_signal): Erased the signum parameter - name to avoid a nasty warning about arguments not used when - instantiating templates. Thanks to Gonzalo Diethelm - <gonzo@ing.puc.cl> for reporting this. - - * ace/OS.h: Added the ACE_Export symbol to the definition of - ACE_Str_Buf. This makes it compile and link on NT. Thanks to - Prashant for noticing this (our favorite Win32ism...). - - * ace/Thread.h (ACE_Thread): Removed a default argument for one of - the ACE_Thread::join() wrappers so this won't be ambiguous with - the other join() wrapper. - - * ace/OS: Added a new wrapper for strtok_r(). - -Sun Sep 29 16:12:01 1996 Prashant Jain <pjain@merengue.cs.wustl.edu> - - * netsvcs/lib/: Renamed the project file for Win32 from lib.mdp to - netsvcs.mdp. Also the original project file did not include some - files such as Naming_Handler.cpp and Server_Logging_Handler.cpp - and I fixed that. Finally removed two files System_Time.{h,cpp} - which are already present in ace/. - -Sat Sep 28 16:34:56 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/OS: Added a new overloaded select() method that takes a - const ACE_Time_Value &. This is useful for situations where you - are passing in ACE_Time_Value::zero. - -Fri Sep 27 16:20:46 1996 Douglas C. Schmidt <schmidt@polka.cs.wustl.edu> - - * ace/ACE: Added a fix for the fact that VxWork's write() call - doesn't take a const char *. - - * ace: Started adding support for VxWorks and GreenHills compiler, - e.g., added the config-vxwork-ghs-1.8.h file. Thanks to David - Levine <levine@cs.wustl.edu> for getting this rolling! - -Thu Sep 26 00:15:46 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Timer_Queue: Changed the public interface methods to be - virtual in order to make it possible to override them in - subclasses. This makes it feasible to implement different types - of Timers. - - * ace/OS: Added a wrapper for the strspn() string call. Thanks to - Irfan for noticing this omission. - - * ace/Synch_T.cpp (wait): Changed the line: - - return ACE_OS::cond_wait (&this->cond_, this->mutex_); - - to - - return ACE_OS::cond_wait (&this->cond_, &this->mutex_.lock_); - - Thanks to Dieter Quehl <dietrich.quehl@med-iss1.med.siemens.de> - for noticing this. - - * ace/config-sunos5.4-g++.h: Removed the #define for - ACE_HAS_BROKEN_RANDR and replaced the ACE_HAS_SVR4_SIGNAL_T with - ACE_HAS_CONSISTENT_SIGNAL_PROTOTYPES since it looks like the - latest gcc release (2.7.2) fixes this in their own header files. - -Sat Sep 21 10:45:43 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/OS.h: Added a new #define called ACE_HAS_BROKEN_MSG_H to the - config-osf1-3.2.h file and used it in OS.h to work around - problems with <msg.h> prototypes on that platform. - -Fri Sep 20 00:15:29 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * Released version 4.0.31 for testing. - - * ace/Pipe.cpp: Initialize handles_ to ACE_INVALID_HANDLE in - default constructor. Thanks to Tim Harrison for pointing this - out. - - * ace: Copied in new versions of ace.{mak,mdp} for Win32. - - * ace: Added TTY_IO.cpp to the Makefile. - - * ace/config-win32-msvc[24].0.h: Updated the config file so that - it *doesn't* #define ACE_HAS_STRBUF_T since this type clearly - isn't available on Win32! - - * ace: Modified all of OS.i and config-*.h files so that they - would be consisten with respect to handling the size_t and int - differences in socket implementations. Thanks to Chuck Gehr - <gehr@sweng.stortek.com> for helping with this for AIX. - - * ace/ACE.h (ACE): Added a new method called max_handles() that - returns the maximum number of open handles currently supported - by the process. - - * examples/Reactor/Misc/signal_tester.cpp: Revised the test to - utilize the new idioms for programming with signals. - - * ace/OS.h: added a new #define called ACE_DEV_NULL that defaults - to "/dev/null" on UNIX and "nul" on NT. Thanks to David Trumble - <trumble@steosf.nio.dec.com> for reporting this fix. - - * ace/Log_Msg.cpp: Added some checks to make sure that we don't - try to strdup() if we are passed a NULL pointer. Thanks to Luca - for suggesting this. - - * ace/OS: Move ACE_Str_Buf into OS.{h,i} and remove the Str_Buf.h - file. - - * Makefile: Added the "performance-tests" directory to the list of - directories we build when making ACE. - - * ace: Moved the definition of strbuf from Str_Buf.h into OS.h. - Thanks to Irfan for recommending this. - - * ace/Makefile: Added some additional sed magic on the - Svc_Conf_y.cpp file in order to remove the very last warnings - from MSVC++! - -Thu Sep 19 00:00:17 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Service_Config.cpp (open): Only initialize the logger to use - STDERR if the user hasn't already set the ACE_Log_Msg::flags(). - Thanks to Tom Leith <trl@icon-stl.net> for suggesting this. - - * ace/OS: Removed all traces of the ACE_HAS_INT_SOCKNAME and - ACE_HAS_LENPTR_SOCKOPT since Chris Lahey's new fixes for AIX - obviate the need for these. - - * ace/OS.i: Only #include <rpc/rpc.h> if the platform has RPC! - Thanks to Chuck Gehr <gehr@sweng.stortek.com> for suggesting - this. - - * ace: Removed all uses of ACE_HAS_SETOWN and replaced them with - explicit tests for F_SETOWN and FASYNC. This is more portable. - Thanks to Chuck Gehr <gehr@sweng.stortek.com> for suggesting - this. - - * ace/OS: Added a new #define called ACE_HAS_SIZET_SOCKET_LEN to - handle platforms where the length parameter of bind(), - connect(), accept(), etc. uses size_t rather than int. This - helps to get ACE working on MVS. Thanks to Chuck Gehr - <gehr@sweng.stortek.com> for suggesting this. - - * ace/OS: Added Chris Lahey's fixes that make the - getprotoby{name,number}_r() functions work for AIX. - - * ace: Changed the ACE_HAS_STRUCT_HOSTENT_DATA to - ACE_HAS_STRUCT_NETDB_DATA because we use a single symbol to - refer to all of the odd netdb.h stuff that AIX has... - - * ace: Changed all uses of: - - iovec *iovp = (iovec *) alloca (total_tuples * sizeof *iovp); - - to - - iovec *iovp = (iovec *) alloca (total_tuples * sizeof (iovec)); - - to keep the AIX compiler from complaining (falsely) about using - iovp before it is initialized. Thanks to Chris Lahey for - reporting this. - - * ace/OS.h: Added Chris Lahey's changes that handle AIX's - _XOPEN_EXTENDED_SOURCE features without polluting all the socket - implementations! - - * ace/Thread.cpp (spawn_n): Removed an unreferenced local variable - so that the Win32 compiler doesn't complain. - - * ace/OS.h: Added the definition for strbuf{} for NT. - - * ace: Removed the msg_hack.h file since it had OSF and DEC - copyright info in it. Replaced this with Antonio Tortorici's - <antonio@rh0011.roma.tlsoft.it> clever use of _KERNEL and the - new ACE_LACKS_SYSV_MSQ_PROTOS. - - * ace/INET_Addr.h: Updated the documentation to indicate more - clearly the use of getservbyname(). - - * ace/OS.cpp (thr_create): Added basic hooks to support the use of - AfxBeginThread on Win32. This is necessary to allow ACE to work - seemlessly with MFC applications. Added an THR_USE_AFX flag - that can be "or'd" in with the other thread flags in calls to - ACE_OS::thr_create(). If this flag is enabled *and* if we are - compiling with ACE_HAS_MFC enabled, then AfxBeginThread() is - called rather than _beginthreadex(). - - * ace/INET_Addr.h (set): Fixed a typo in the documentation for - set() (the order of "host:port" was backwards...). Thanks to - Brad Flood <BFLOOD@tcs.lmco.com> for reporting this. - -Wed Sep 18 00:36:01 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/SOCK_IO.cpp: Added a new recv() method that allows a client - to read from a socket without having to provide a buffer to - read. This method determines how much data is in the socket, - allocates a buffer of this size, reads in the data, and returns - the number of bytes read. The caller is responsible for - deleting the memory. Thanks to Luca Priorelli - <lucapri@mbox.vol.it> for suggesting this. - - * ace/OS.h: Added a special #ifdef for IRIX 6.2 threads so that - THR_BOUND and THR_SCOPE_SYSTEM are different. Thanks to Gonzalo - Diethelm <gonzo@ing.puc.cl> for reporting this. - - * ace/Message_Block.i (msg_class): Added a new "class" of messages - to ACE_Message_Block: MB_USER. This is useful for writing - extensible applications a la Microslush Windows MSG stuff... - -Tue Sep 17 16:38:44 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Message_Block: Changed the signature of the - ACE_Message_Block constructors (and init()) so that they take - const char * rather than char *. In addition, changed the - definition of one of the constructors (and init()) so that it - takes a size field in addition to the buffer. - - * ace/Message_Block.cpp (size): Fixed a bug in the - ACE_Message_Block::size() method -- we were failing to deal with - allocators and ownership correctly during a resize. Thanks to - Amos Shapira <amos_shapira@mail.icomverse.com> for reporting - this. - - * ace/Naming_Context.cpp: Removed the source of yet another - warning about "inconsistent dll linkage. dllexport assumed." - - * ace/Mem_Map.cpp (map_it): Added a cast to size_t (file_len) - because by this time we know that file_len >= 0. This avoids - yet another warning on WinNT! - - * ace/Reactor.h: Fixed the remaining warnings about - "signed/unsigned mismatch" in Win32 by changing the type of - cur_size_ from size_t to ssize_t. - - * ace/Log_Msg.cpp: Modified the code so that on NT we use - ACE_SPIPE_Msg rather than ACE_FIFO_Send_Msg. Thanks to Luca - Priorelli <lucapri@mbox.vol.it> for suggesting this. - - * ace/OS.i: Implemented the and put[p]msg() wrappers by being - smart about allocating and copying data. - - * ace/TTY_IO.cpp (control): There was one too many end parentheses - on line 192 of TTY_IO.cpp. Thanks to Dave Trumble - <trumble@steosf.nio.dec.com> for reporting this fix. - - * ace/Log_Msg.cpp (local_host): Fixed the use of program_name_ and - local_host_ so that they strdup() the values passed by the - users, rather than copying pointers. This avoids problems if - the user doesn't pass in static memory. Thanks to Luca - Priorelli <lucapri@mbox.vol.it> for reporting this. Somehow - this change got lost and I've reapplied it... - - * ace/Log_Record.cpp (round_up): Added an extra + 1 to the length - since otherwise the final '\0' gets lots if len is a multiple of - 8. Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting - this. Somehow this change got lost and I've reapplied it. - - * ace/Memory_Pool.h: removed #if defined (ACE_HAS_SIGINFO_T) logic - from both handle_signal() definitions (ACE_Shared_Memory_Pool - and ACE_MMAP_Memory_Pool). Thanks to Chris Lahey for fixing - this. - - * ace/OS.h: Moved the define of SA_RESTART below the #include for - signal.h. Otherwise SA_RESTART will always be defined by OS.h, - since SA_RESTART is defined on AIX in signal.h. Thanks to Chris - Lahey for fixing this. - - * ace/OS.h: Added some new #pragmas to suppress harmless warnings - for the MSVC++ compiler. - -Tue Sep 17 13:20:53 1996 Prashant Jain <pjain@merengue.cs.wustl.edu> - - * ace/Local_Name_Space_T.cpp: Modified ACE_Local_Name_Space:: - create_manager () so that all three naming scopes use the - database variable defined in Name Options. This allows us to - specify different names for databases for all three naming - contexts. However, it is imporant to note that this can lead to - potential problems where, for example, a process may use the - same name for PROC_LOCAL database as an already existing - NET_LOCAL database. - -Mon Sep 16 01:31:21 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * examples/Logger/simple-server/Logging_Handler: get_handle(), - handle_input(), and handle_close() want the right types - (ACE_HANDLE instead of int). Thanks to Luca Priorelli - <lucapri@mbox.vol.it> for reporting these. - - * examples/Logger/simple-server/Logging_Acceptor.cpp: Fixed a typo - (Log_Mskg.h should be Log_Msg.h of course...). In addition, - changed the use of -1 to ACE_INVALID_HANDLE. Thanks to Luca - Priorelli <lucapri@mbox.vol.it> for reporting these. - - - * ace: Changed all uses of ACE_HAS_ACE_INLINED_OSCALLS to - ACE_HAS_INLINED_OSCALLS. This was a vestiage of a global - replace gone amok. Thanks to Alan Stweart <Axs2@osi.com> for - reporting this! - - * ace/Log_Msg.cpp (open): Added a check for the OSTREAM flag in - the ACE logger. Thanks to Rick Orr - <rorr@costello.den.csci.csc.com> for noticing this. - - * Released version 4.0.30 for testing. - - * netsvcs/clients/Naming/Dump_Restore/Dump_Restore.cpp - (Dump_Restore): Deleted an extra "return 0;" within a - constructor (duh...). - - * examples/Threads/test_process_{semaphore,mutex}.cpp (main): - Fixed some annoying G++ compiler bug related problems. We need - to use old-style C casts to prevent ambiguous parsing. - - * examples/ASX/Event_Server/Transceiver/transceiver: Rewrote this - example to illustrate how to use the ACE_Connector and - ACE_Svc_Handler. - - * examples/ASX/Event_Server/Transceiver/transceiver: Finally clued - in and realized that it is just not suitable to implement the - event server transceiver with separate threads for input and - output. It is simply to non-portable to get these shut down - gracefully. I think John Ousterhout was right -- threads are - evil! - - * examples/ASX/Event_Server: Merged the Consumer/Supplier - directories into a single Transceiver directory to reflect the - fact that the Consumer and Supplier were completely symmetrical! - - * ace/Module.cpp (close): Don't delete the Tasks in a Module if - there are still threads running in them. Otherwise we'll end up - with a big mess. - -Mon Sep 16 15:50:45 1996 Prashant Jain <pjain@merengue.cs.wustl.edu> - - * performance-tests/Misc/test_naming.cpp: Added a new test to the - performance-tests directory called test_naming which simply does - performance testing on Naming Service. The test runs both the - SYNC and the NO-SYNC version of Naming Service. - -Mon Sep 16 15:22:52 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu> - - * ace/Proactor.cpp (initiate): Added a check for - ERROR_NETNAME_DELETED after ReadFile/WriteFile. Now the - initiating handler is immediately dispatched for EOF *and* - closed connections. Thanks to Luca Priorelli - <lucapri@mbox.vol.it> for suggesting this change. - -Sun Sep 15 00:55:59 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * Fixed all uses of ACE_Service_Config::end_event_loop() and - ACE_Service_Config::run_event_loop() to be - ACE_Service_Config::end_reactor_event_loop() and - ACE_Service_Config::run_reactor_event_loop() since we now have - to consider the other event loops (e.g., Proactor and ReactorEx) - and it doesn't seem right to relegate those to 2nd class status. - - * ace: Finally got fed up with all the #ifdefs required to deal - with extended signals and just changed the - ACE_Event_Handler::handle_signal() method to always use the - extended signal interface. Fortunately, we can use default - values to hid this from callers (though you may need to change - your class definitions if you were assuming the - handle_signal(int) interface. - - * ace/Memory_Pool.h: Changed all the methods of the various - Memory_Pool classes to be virtual so that subclasses can - selectively override them. This shouldn't affect performance - since all existing use cases work directly with the "derived" - classes themselves, so there shouldn't be any overhead since the - compiler can use direct calls rather than virtual function - calls. - - * ace/OS.cpp (thr_create): Changed the call to CreateThread() to - _beginthreadex() and the call to ExitThread() to _endthreadex() - for Win32 in order to make ACE threads work correctly with - Win32. Thanks to James Mansion <james@wgold.demon.co.uk> for - recommending this. - - * ace/ACE: Added two new static functions: read_adapter() and - register_stdin_handler(). These are useful when writing code - that must demultiplexing ACE_STDIN on both Win32 and UNIX. This - works around Win32 limitations that don't allow us to select() - on non-sockets (such as ACE_STDIN). - - * examples/ASX/CCM_App/SC_Server.cpp: Updated this - test so that it should now work correctly on Win32, where it - isn't possible to select() on STDIN... - - * ace/Synch_T: Added a new class to ACE called "ACE_Test_and_Set." - As this name implies, this class implements an atomic ``test and - set'' abstraction. This has all sorts of useful implications, - particularly because it is a template that can be paramaterized - by the type of LOCK (e.g., ACE_Null_Mutex, ACE_Thread_Mutex, - etc.) and the type of TYPE (e.g., int, double, sig_atomic_t, - etc.). In addition, because this "is-a" ACE_Event_Handler it - instances can be registered with the Reactor and used to shut - down event hoops gracefully upon receipt of certain signals - (e.g., SIGINT). In fact, I've redone many of the example - applications (e.g., ./examples/Logger/server/server_loggerd.cpp) - to illustrate how this works. - -Sun Sep 15 20:40:17 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu> - - * ace/ReactorEx.cpp (notify): I've redesigned this code. - Previously, ReactorEx was explicitly managing a handle that it - kept in handles_[0]. handles_[0] was used to implement - ReactorEx::notify, which allowed other threads to wake up the - thread waiting in ReactorEx::handle_events. Now ReactorEx has - an Event_Handler (ReactorEx_Notify) that is registered in the - constructor of ReactorEx. This allows us to treat events from - handles_[0] just like every other event (i.e. by dispatching to - handles_[0]->handle_signal). One of the results of this change - is that code in remove_handler() is simplified a bit. - -Sun Sep 15 17:56:52 1996 Prashant Jain <pjain@merengue.cs.wustl.edu> - - * ace/Naming_Context.cpp: Added a new flag to the constructor and - open() method of ACE_Naming_Context that allows us to specify - which Memory_Pool to use when creating ACE_Local_Name_Space - (that is choose between ACE_MMap_Memory_Pool and - ACE_Lite_MMap_Memory_Pool). - - * ace/Memory_Pool.cpp: Added a new class called - ACE_Lite_MMap_Memory_Pool which subclasses ACE_MMap_Memory_Pool - and overrides the sync method so that it is a no-op. - - * ace/Local_Name_Space.cpp: Made some siginificant changes in - ACE_Local_Name_Space. Here is what the problem was: - ACE_Name_Space_Map (which is an ACE_Map_Manager) used an - ACE_RW_Process_Mutex for synchronization. However, since the Map - was kept in shared memory and was shared by all the processes, - it got instantiated only by the first process which came - along. Therefore, only the first process got around to creating - and initializing the lock. - - In fixing the problem, we made some other changes to - ACE_Local_Name_Space and ACE_Name_Space_Map. Both classes are - now template classes. ACE_Local_Name_Space needs to be - parameterized with a Memory_Pool (thus giving us a hook to - implement the NO-SYNC option) as well as a LOCK. - ACE_Name_Space_Map needs to be parameterized by an ALLOCATOR - which is created by ACE_Local_Name_Space. Note that the reason - we need to parameterize ACE_Name_Space_Map is so that we can - pass an ACE_Allocator_Adapter (which subclasses from - ACE_Allocator) with every method. It is not possible to pass an - ACE_Allocator since the ::remap() method relies on an - allocator() method defined on the ALLOCATOR that is passed in - (and ACE_Allocator does not define an allocator() method). - - The purpose of the class ACE_Name_Space_Map still remains the - same. It IS_A Map_Manager and provides the hook to set the - allocator to the process specific one. However, none of its - methods acquire any locks. For that reason, the Map_Manager is - parameterized with the Null_Mutex. All synchronization takes - place inside ACE_Local_Name_Space. ACE_Naming_Context - instantiates ACE_Local_Name_Space (depending upon the scope) and - by default parameterizes it with ACE_MMap_Memory_Pool and - ACE_RW_Process_Mutex. - - Also made some more fixes to ACE_Local_Name_Space. In - create_manager(), after we create the allocator, we now check to - see if the backing store was created successfully and if not, we - return -1. - -Sat Sep 14 00:00:31 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * examples/Logger: Renamed the original server directory to - "simple-server" and added a new directory called - "Acceptor-server" which implements the Logger using the - ACE_Acceptor. Note that almost all of the implementation code - disappears! - - * ace/Local_Name_Server_T.cpp: Removed the name_server_map_ array - and replaced it with the ACE_NAME_SERVER_MAP #define, which is - now contained in OS.h. - - * ace/Malloc.h: Added "virtual ... = 0" to the bind() and - trybind() methods of the ACE_Allocator since they should be pure - virtual functions... - - * ace/Synch{_T}: Separated out the wait (ACE_Time_Value *) and - wait (void) methods in order to optimize the call sequence for - the common case when there is no timeout. - - * ace/Synch: Added a new wait(ACE_Thread_Mutex &) method to - ACE_Condition_Thread_Mutex so that we are consistent with the - templated ACE_Condition_Mutex. - - * include/makeinclude: Changed uses of -pic to -PIC because ACE is - now creating more than 2082 symbols. It's probably time to - split up the library... - - * ace/DEV_IO: Moved the ACE_DEV_Addr instance from ACE_DEV_IO into - ACE_DEV so that it will be available for the ACE_DEV_Connector. - This fixes a bug that prevented us from using the ACE_Connector - in conjunction with the ACE_DEV_* classes. Thanks to Karlheinz - for clarifying what had to occur. - -Fri Sep 13 00:16:32 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/OS.h: Changed the order of #includes so that <assert.h> - comes before <sys/stat.h>. This fixes some bugs with the - Siemens SVR4 C++. Thanks to Antonio Tortorici - <antonio@rh0011.roma.tlsoft.it> for this fix - - * ace/ACE.cpp (handle_timed_complete): Added yet another weird - hack to deal with the insanity that is TLI... - - * ace/Synch.cpp: Replaced all uses of ACE_Thread_Mutex_Guard with - ACE_GUARD macros in order to avoid problems when mutexes fail. - - * ace/OS.h: Changed the definition of the ACE_*GUARD macros so - that they are always enabled, even when we turn off ACE_MT_SAFE. - This avoids a nasty semantic problem for components that use - ACE_Process_Mutex. Thanks to Avraham Nash - <Avraham_Nash@praxisint.com> for reporting this problem. - - * ace/OS: Removed ACE_OS::fork_exec() since its functionality has - been subsumed by ACE_Process. - - * ace/Thread_Manager: Added a new thread_descriptor_i() method - that *doesn't* grab the lock in order to avoid deadlocks. - - * include/makeinclude/platform_sunos5_sunc++.GNU (CXX): had to add - the -pta option so that we achieve template closure in ACE. - - * include/makeinclude: Added -lthread to the - platform_sunos5_sunc++.GNU file. I don't know how this slipped - through the cracks! - - * ace/{DEV_IO,FILE_IO,SOCK_IO,SPIPE_Stream}: Fixed a braino with - alloca where I was failing to multiply by sizeof (iovec). Isn't - C great? ... Thanks to Chuck Gehr <gehr@sweng.stortek.com> for - reporting this. - - * ace/SOCK_Dgram_Mcast.cpp: Added two changes to the ACE multicast - code in order to get it to work on Win32. The first change is - to put the IP_ADD_MEMBERSHIP setsockopt() call *after* the - bind() (in shared_open()). The second is to convert the - ACE_INET_Addr::get_ip_address() from host byte order into - network byte order. Thanks to Todd L. Montgomery - <tmont@cerc.wvu.edu> and Steve Weismuller - <spweismu@rsoc.rockwell.com> for helping with this. - - * examples/Threads/test_barrier2.cpp: Incorporated Karlheinz's - new ACE_Barrier test program. - - * ace/Synch.h: Added Karlheinz's ACE_Null_Barrier class. - -Fri Sep 13 00:30:50 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu> - - * tests/{Tokens_Test,Time_Service_Test}.cpp: Updated tests to use - ACE_Process instead of ACE_OS::fork_exec. - - * ace/Process.cpp: Added a new ACE_Process abstraction that is a - Portable encapsulation for creating new processes. It allows - assignment of STDIN, STDOUT, and STDERR of the new process. On - UNIX, ACE_Process uses fork and exec. On Win32, it uses - CreateProcess. Since we can set the standard handles, we can - mimic UNIX pipes on Win32 by building chains of processes. This - class should be used instead ACE_OS::fork_exec. - - * examples/OS/Process/process.cpp (main): Added new example - application to show how to use ACE_Process. - -Thu Sep 12 00:55:25 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/DEV_IO: Added methods get_local_addr() and get_remote_addr() - so that ACE_Connector will work correctly. Thanks to Brad Flood - <BFLOOD@tcs.lmco.com> for reporting this. - - * ace/Thread_Manager.cpp (thr_self): Added a fix to solve the - problem that Win32 GetCurrentThread() returns a pseudo-handle - rather than a real handle. Now, we just look things up using - the thread id rather than the thread handle. Thanks to Luca - Priorelli" <lucapri@mbox.vol.it> for clarifying this. - - * ace/Proactor.cpp (initiate): Fixed an incorrect set of return - values -- they were reversed. Thanks to Brad Flood - <BFLOOD@tcs.lmco.com> for reporting this. - - * ace/OS.i (thr_cmp): Added a check for - !defined(ACE_HAS_SETKIND_NP) to avoid a problem with OSF/1. - Thanks to Martin Schoeckle <schoeckle@ike.uni-stuttgart.de> for - reporting this. - - * examples/IPC_SAP/DEV_SAP: Updated these examples to use the new - ACE_TTY_IO classes. - - * ace: Moved the TTY_IO code from the - examples/IPC_SAP/DEV_SAP/{reader,writer} directories into the - files TTY_IO.{h,cpp} in the main part of ACE and integrated Brad - Flood's <BFLOOD@tcs.lmco.com> changes for Win32. - - * ace/DEV_IO.i: Changed the mapping of send_n() and recv_n() - methods to use write_n() and read_n() respectively so they will - work on NT. Thanks to Brad Flood <BFLOOD@tcs.lmco.com> for - reporting this. - - * ace/Thread_Manager.h: Implemented a non-synchronized version of - the lookup function for the <hthread_descriptor>. This version - assumes that the lock is help. We need this to avoid - intra-class method deadlock on systems (such as Solaris) that - lack recursive mutexes. - - * ace/Log_Msg.cpp (ACE_Log_Msg): made sure to initialize - ACE_Log_Msg::thr_handle_ to 0. I'm not sure how this got - changed... Thanks to Luca Priorelli <lucapri@mbox.vol.it> for - reporting this. - - * examples/Reactor/ReactorEx/test_reactorEx.cpp - (register_thread_exit_hook): Changed hthread_t to ACE_hthread_t. - Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting - this. - - * apps/Gateway/Gateway/Channel.h: Due to inconsistencies between - the semantics of sockets and TLI with respect to establishing - non-blocking connections it's not a good idea to use TLI in - conjunction with select(). Therefore, I've #if 0'd out the use - of TLI in the Gateway application. - -Wed Sep 11 00:25:38 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/ACE.cpp (handle_timed_complete): Fixed a typo that was - failing to set n = ACE::recv(...). In addition, rethought how - we figure out if a connection completes for the nth time... - - * ace/TLI.cpp (open): Modified the implementation of open() so - that if oflag == 0 it is given an initial value of O_RDWR. - Otherwise we'll get a "badflags" t_errno. - - * ace/Connector.h (connect): Modified connect() so that the - default value of the flags parameter is O_RDWR. This is - necessary to make TLI_Connector::connect() work correctly by - default. - - * examples/Logger: Updated the example logger client and server to - illustrate more clearly how things like the Singleton Reactor - and the ACE_Reactor timer mechanism work. Thanks to Joe - DeAngelis <bytor@faxint.com> for suggesting this. - - * ace/Pipe: Added a new constructor that makes it possible to - initialize the <ACE_Pipe> from the <read> and <write> handles. - Thanks to Stevan Warwick (sjw@aesthetic.com) for suggesting - this. - - * config-irix5.3-sgic++.h: Added #define for ACE_NEEDS_SYSTIME_H. - Thanks to Stevan Warwick (sjw@aesthetic.com) for reporting this. - - * examples/Logger/server/Client_Acceptor: Fixed some stray - mis-uses of int that should have been ACE_HANDLE. Thanks to - Luca Priorelli" <lucapri@mbox.vol.it> for reporting this. - - * ace/{ACE,Log_Msg}.cpp: Added fixes for hexdump(). Thanks to - Luca Priorelli" <lucapri@mbox.vol.it> for supplying these. - - * ace/Reactor.cpp (ACE_Reactor): Fixed a typo: "this->max_handlep1 - ()" should be "this->handler_rep_.max_handlep1 ()". Thanks to - Scott Shupe <shupes@mitre.org> for reporting this. - - * apps/Orbix-Examples/Event_Comm: Added a bunch of changes to make - this application compile with Orbix 2.0. Thanks to Mike - O'Malley <momalley@caesun16.msd.ray.com> for the fixes. - - * ace/OS.cpp (thr_create): Added yet another fix for the IRIX 6.2 - pthreads implementation. Thanks to Gonzalo Diethelm - <gonzo@ing.puc.cl> for reporting this. - - * ace/config-irix6.2-sgic++.h: Changed ACE_HAS_IRIX53_GETTIMEOFDAY - to ACE_HAS_IRIX_GETTIMEOFDAY because this also seems to be the - case for IRIX 6.2... Thanks to Gonzalo Diethelm - <gonzo@ing.puc.cl> for reporting this. - - * ace/TLI_{Connector,Acceptor}.cpp: Added tests against NULL - pointers to avoid segmentation faults when the TLI - implementation doesn't allocate memory for the udata and opt - fields of netbuf structures. - - * ace/Mem_Map.i (ACE_Mem_Map): Added an accessor so that callers - can get the name of the filename that is being used as the - backing store. Thanks to the James Mansion - <james@wgold.demon.co.uk> for recommending this. - -Tue Sep 10 00:26:52 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/OS.cpp (thr_create): Modified the thr_create() - implementation for Win32 so that if the caller doesn't care - about this value we can avoid a HANDLE leak. Thanks to the - James Mansion <james@wgold.demon.co.uk> for recommending this. - - * ace/Thread.cpp (ACE_Thread): Moved both definitions of spawn_n() - into the Thread.cpp since they have loops and don't benefit from - being inlined. - - * ace/Svc_Handler.h: Moved operator delete() into the public part - of the class in order to make various compilers happy... - - * ace/OS.i (ACE_OS): Fixed the #define that selects the (union - wait *) alternative of wait(). This original was protected by - ACE_LACKS_POSIX_PROTO, but it should be ACE_HAS_UNION_WAIT. - - * performance-tests: Created a new directory that will contain all - of the ACE performance tests. Move the Synch-Benchmarks and the - TTCP tests from ./apps into here, and also moved the - test_mutex.cpp and test_singleton.cpp files from - ./examples/{Threads,Misc}, respectively. Thanks to Tim Harrison - for this suggestion. - - * ace/OS.i (ACE_OS): in WIN32 closesocket() returns 0 if call is - OK, so I changed the return value to be the other way around. - Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting - this. - - * ace: Changed the ACE_NO_POSIX_PROTO #define to something more - meaningful: ACE_LACKS_POSIX_PROTO. Thanks to Jonathan Biggar - <jon@sems.com> for suggesting this. - - * ace/config-sunos4-g++.h: Added the #define ACE_NEEDS_SYSTIME_H. - Thanks to Alexandre Karev <akg@na47sun05.cern.ch> for reporting - this. - - * ace/OS: Fixed a bunch of pthreads portability problems that - showed up on OSF/1 4.0. Also added support for asctime_r() and - ctime_r() for OSF/1 4.0. Thanks to Dave Trumble - <trumble@steosf.nio.dec.com> for reporting these fixes. - - * ace/Synch_T.cpp (ACE_TSS_Read_Guard): Removed a stray "new" that - was causing problems for the ACE_NEW macro. Thanks to Dave - Trumble <trumble@steosf.nio.dec.com> for reporting this. - - * ace/Local_Tokens.h: Fixed a broken use of "friend", which was - missing the keyword "class." Thanks to Dave Trumble - <trumble@steosf.nio.dec.com> for reporting this. - - * ace/config-osf1-4.0.h: Included Dave Trumble's - <trumble@steosf.nio.dec.com> config file for OSF/1 4.0. - - * include/makeinclude/platform_osf1_4.0.GNU: Included Dave - Trumble's <trumble@steosf.nio.dec.com> platform macros file for - OSF/1 4.0. Also renamed platform_osf1.GNU to - platform_osf1_3.2.GNU to deal with the new version. - - * ace/Proactor: There wasn't a way to destroy an - ACE_Overlapped_File object without closing the ACE_HANDLE - attached to it. Therefore, I added a flag that keeps track of - whether we have to delete this or not. Thanks to Amos Shapira - <amos_shapira@mail.icomverse.com> for suggesting this. - - * examples/Threads/test_future[12].cpp: Updated the tests to use - the new call() semantics in order to shut down the Scheduler's - event loop gracefully. - - * ace/Method_Object.cpp: Added a return value to the call() - routine. This can be used to indicate to the caller that it is - necessary to shut down the event loop. - -Mon Sep 9 02:07:08 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * ace/Service_Config.cpp (ACE_Service_Config): #ifdef's out the - registration of signal handling to control reconfiguration on - Win32 since it doesn't really handle signals very well. Thanks - to John Morey <jmorey@tbi.com> for bringing this to my - attention. - - * ace/CORBA_Handler: Replaced CORBA_[123] with ACE_CORBA_[123]. - - * examples/CORBA: Updated the test programs to work portably - across different versions of Orbix. - - * ace/OS: Added a new wrapper for the getcwd() call. - - * examples/Threads/test_recursive_mutex.cpp: Added the use of - ACE_Guard<> to illustrate how these work with the - ACE_Recursive_Thread_Mutex. Thanks to Gonzalo Diethelm - <gonzo@ing.puc.cl> for motivating me to do this. - - * examples/Threads/test_process_{mutex,semaphore}: Added two new - tests to illustrate how the ACE_Process_Mutex and - ACE_Process_Semaphore work, respectively. - - * ace/Synch: Replaced the implementation of ACE_Process_Semaphore - to use SV_Semaphore_Complex on UNIX platforms in order to get - the same semantics for Win32 and for UNIX. Thanks to the James - Mansion <james@wgold.demon.co.uk> for recommending this. - - * ace/OS.h: Added some parens around the ACE BIT* macros so that - the precedence levels would be dealt with correctly and we don't - get any nasty surprises... - - * ace/{Synch_T,Synch}: Modified the implementation of all the - *acquire()/release() methods so they keep track of whether they - own the mutex. Thus, if a code path needs to give up the mutex - within the lifetime of the mutex, and it calls mutex_.release(), - then the destructor will not call it again. Thanks to the James - Mansion <james@wgold.demon.co.uk> for recommending this. - - * ace/{Synch_T,Synch}: Changed the name of the field result_ to - owner_ for the ACE_Thread_Muetx_Guard and ACE_Guard. This is - more representative of the true purpose of this field. - - * ace/Synch: Updated ACE_Thread_Mutex_Guard so that it has the - same interface and semantics of ACE_Guard. Thanks to the - ever-vigilant James Mansion <james@wgold.demon.co.uk> for - noticing this. - - * examples/Log_Msg/test_log_msg.cpp (main): Added a test of the - new ACE_Log_Msg::priority_mask() functionality. - - * ace/Log_Msg.cpp: Added a new method called priority_mask(), - which updates the new thread-specific priority_mask_ data member - with the new mask and returns the old mask. This is useful for - applications written using ACE_Log_Msg. Often, these have log() - calls with low priority such as LM_DEBUG that don't need to be - printed, but for which the logging code should not be removed. - The priority_mask() scheme makes it possible to selective enable - printing of certain priorities. Thanks to Rochi Febo Dommarco - <rocky@alter.it> for suggesting this. - - * netsvcs/clients/Logger/indirect_logging.cpp (main): Modified the - test program so that it randomly selects logging priorities that - are powers of two. - - * ace/Log_Priority.h: Renumbered the LM_* logging flags so that - they are all powers of two. This makes it easy to implement a - scheme for selectively printing only certain logging values. - -Sun Sep 8 10:46:40 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Proactor.cpp: Fixed up the error handling in ACE_Proactor so - that it returns an error both in case of "bad errors," as well - as when ACE_WIN32 isn't defined. Thanks to Amos Shapira - <amos_shapira@mail.icomverse.com> for reporting this. - -Sun Sep 8 14:11:08 1996 Tim H. Harrison <harrison@lambada.cs.wustl.edu> - - * examples/Reactor/Proactor/README: Updated the test_proactor.cpp - and README files to clarify the relationship between the - Proactor and ReactorEx. This example uses the Proactor as the - main event loop (not the Reactor or ReactorEx). Thus, this - application can only do overlapped I/O and timers - asynchronously. To be able to react to other Win32 events, see - the ACE_ReactorEx and the examples/Reactor/ReactorEx/ test. - Thanks to Amos Shapira <amos_shapira@mail.icomverse.com> for - pointing out the ambiguity. - -Sat Sep 7 14:09:21 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Task.cpp: Enhanced the activate() method so that the caller - can set the priority and the thread group id. Thanks to - Karlheinz for this suggestion. - - * ace/OS.h: Added default values of 0 for the trailing arguments - for the {mutex,sema,cond}_init() methods. - - * examples/Threads/test_mutex.cpp: Added a new test program that - illustrates the difference between implementations of thread - mutex wrappers that use inheritance and dynamic binding vs. the - ACE approach (which doesn't use inheritance and dynamic - binding). The results I got on my SPARCstation 20 model 712 is - included in the source file. Thanks to James Mansion - <james@wgold.demon.co.uk> for motivating me to write this. - - * examples/Misc/test_singleton.cpp: Added a new test program that - illustrates the performance of using the Double-Checked Locking - pattern compared with the standard "Mutex::acquire()/release()" - approach. Thanks to Jim Coplien <cope@research.bell-labs.com> - for encouraging me to get these performance numbers. - -Tue Sep 3 00:38:47 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/XtReactor: Added minor fixes to XtReactor to fix complaints - about "bool" not being defined and the destructor - ~ACE_XtReactor() has already having a body. Thanks to Andres - Kruse <Andres.Kruse@cern.ch> for these fixes. - - * ace/Mem_Map.cpp: Make sure that this->length_ is initialized to - 0 in ACE_Mem_Map::map (). Thanks to James Mansion - <james@wgold.demon.co.uk> for pointing this out. - - * ace/Thread.i (spawn_n): In ACE_Thread::spawn_n the sense of the - following check is wrong: - - for (i = 0; i < n; i++) - // Bail out if error occurs. - if (ACE_OS::thr_create (func, arg, flags, &t_id, 0, priority, - stack == 0 ? 0 : stack[i], - stack_size == 0 ? 0 : stack_size[i]) != 0) - thread_ids[i] = t_id; - else - break; - - The '!=' should be '=='. Thanks to James Mansion - <james@wgold.demon.co.uk> for pointing this out. - - * include/makeinclude/rules.local.GNU (MAKEFILE): Changed the - $WRAPPER_ROOT/include/makeinclude/rules.local.GNU line that - says: - - sed -e "s:$(WRAPPER_ROOT);$$(WRAPPER_ROOT);g" \ - - so that the double dollar is now "\$$" (prefixed the first - dollar sign with a backslash). If not, my shell will try to - execute WRAPPER_ROOT for some reason. With "\$$" it works as it - should. Thanks to Marius Kjeldahl <marius@funcom.no> for - reporting this. - - * Released version 4.0.29 for testing. - - * ace/OS.i (thr_getspecific): Added a new case for OSF/1. Thanks - to Martin Schoeckle <schoeckle@ike.uni-stuttgart.de> for - reporting this. - - * ace/Thread_Manager.cpp (spawn_i): Removed an invalid - initialization of ACE_hthread_t = 0, which doesn't work on all - pthreads platforms because pthreads uses a struct in some - implementations. Thanks to Martin Schoeckle - <schoeckle@ike.uni-stuttgart.de> for reporting this. - - * man: Updated all the nroff and html documentation to conform to - the latest version of ACE. - - * netsvcs/lib/{Name_Handler,TS_Server_Handler}.cpp: Fixed - some mistakes in the ACE_TEMPLATES_REQUIRE_SPECIALIZATION - code so that all the services can be linked together without - multiply defined symbols. - - * netsvcs/lib/Name_Handler.cpp: Fixed a spot where we weren't - passing in an lvalue to send_request(). Why this wasn't showing - up earlier I don't know, but GCC caught it! - -Mon Sep 2 00:47:00 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Thread_Manager.cpp: Updated all comparisons of ACE_thread_t - and ACE_hthread_t so that they use the ACE_OS::thr_equal() and - ACE_OS::thr_cmp() methods, respectively. Thanks very much to - Martin Schoeckle <schoeckle@ike.uni-stuttgart.de> for identify - the need for this. - - * ace/OS: Added a new method called thr_cmp() which compares two - ACE_hthread_t values for equality. Unfortunately, we can't just - compare these directly via == because on some platforms they are - implemented as structs. Right now, I'm assuming that if - ACE_HAS_TID_T is enabled that we can compare tid_t's using ==. - If this turns out to be incorrect (e.g., if tid_t's are also - implemented as structs, please let me know). - - * ace/Future: Changed the overloaded result() method to a pair of - get()/set() methods. - - * tests/test_config.h: Fixed a bug in the reset() routine. This - was originally deleting the global static ace_file_stream. - However, this was causing segmentation faults if destructors for - objects local to main() were trying to write to the output file. - Therefore, instead of deleting the ostream, we simply flush() - it! - - In addition, also renamed the various functions in test_config.h - to make sure they don't conflict with any other names by - prefixing them with ace_test_... - - * ace: Added many small fixes for IRIX 6.2. Thanks to Gonzalo - Diethelm <gonzo@ing.puc.cl> for reporting all of these! - - * ace/OS: Added a wrapper for the UNIX syscon() system call. - - * ace/LSOCK.cpp (recv_handle): Rearranged the casts so that things - work correctly on platforms with odd definitions ot struct - iovec. Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for - reporting this. - - * ace/Task.cpp (ACE_Task_Exit): Rearranged the order in which we - shut down a Task via the Task_Exit hook so that we first - decrement the count of the threads in the task and *then* call - its close() hook. This guards against cases where the close() - hook does something crazy like "delete this". - - * ace/XtReactor.h: Changed #include "X11/Intrinsic.h" to #include - <X11/Intrinsic.h>. Thanks to Gonzalo Diethelm - <gonzo@ing.puc.cl> for suggesting this. - - * ace/Future.cpp (ACE_Future): Added some strategic "consts" to - the assignment operator and copy constructor for ACE_Future and - ACE_Future_Rep. - - * examples/Threads/test_task_three.cpp (main): Revised the test so - that it will shut itself down automatically when all the threads - have finished. - - * examples/Threads/test_task_two.cpp (main): Revised this test so - that it doesn't run forever, but only runs either 1000 times or - as many times as the user specifies on the command line. Thanks - to Gonzalo Diethelm <gonzo@ing.puc.cl> for suggesting this. - - * ace/OS.i: Added an extra #else for thr_sigsetmask(), - thr_min_stack(), and thr_kill() for weirdo platforms that don't - conform to the other threading APIs... - -Sun Sep 1 20:15:28 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * examples/ASX/Message_Queue: Changed the use of read(0, ...) and - write(1, ...) to ACE_OS::read(ACE_STDIN, ...) and - ACE_OS::write(ACE_STDOUT, ...) in buffer_stream.cpp and - bounded_buffer.cpp. - - * ace/OS.i: Fixed the errno mapping of the cond_timedwait() - functions so that they set errno to ETIME rather than EBUSY when - timeouts occur. This is necessary to support Solaris and POSIX - pthreads semantics on Win32. - - * build/SunOS5.5/examples/ASX/Message_Queue/buffer_stream.cpp: - Modified the example somewhat so that it uses the Singleton - thr_mgr() method from ACE_Service_Config. - -Sun Sep 1 17:29:58 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * ace/ACE.cpp (map_errno): Added a new static method to the ACE - class. This method allows us to map troublesome win32 errno - values (e.g. WSAEWOULDBLOCK) to values that standard C strerr - function understands. Thank you Microsoft. - - * ace/Log_Msg.cpp (log): Added a call to ACE::map_errno to the %p - option. Now the ACE logger can begin to map Win32 error values - into meaningful strings. - - * netsvcs/lib/lib.mdp: Added a project file for the netsvcs - library. This builds a dll into ace/netsvcs.dll (not into the - netsvcs/lib directory). This reduces the number of paths needed - in %PATH%. - - * examples/Tokens: Renamed this directory netsvsc/clients/Tokens. - - * ace/ace.mdp: Removed wsock32.lib from the ace files listing. - The problem is that we can't assume where MSDEV is installed. I - added wsock32.lib and advapi32.lib to the - build/settings/link/library_modules line. - - * ace/config-win32-msvc4.0.h: Disabled the "C4355: 'this' : used - in base member initializer list" warning. Thanks to Amos - Shapira for figuring this out for us. Although "this" is - unneeded for win32, it is required for compilers on other - platforms (e.g., AIX). - - * ace/Message_Queue.cpp (dequeue_head_i): Andres Kruse pointed out - that we weren't doing head_->prev (0), when dequeuing! - -Tue Aug 27 21:00:25 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * include/makeinclude/platform_sunos5_sunc++_4.1.GNU (CXX): Added - Andres Kruse's changes for SunC+ 4.1. - - * ace: Fixed line # 12 of ace/config-sunos4-sun4.1.4.h, - which read: - - "#define ACE_HAS_SVSV_IPC" (ACE_HAS_ ess vee ess vee _IPC) - - to - - "#define ACE_HAS_SYSV_IPC" (ACE_HAS_ ess wye ess vee _IPC) - - Fix another problem: - - #define ACE_LACKS_THREAD_STACK_ADDR (OS.cpp) - - was inconsistently defined in: - - #define ACE_LACKS_THREAD_STACK_ADDRESS (config-aix-4.1.x.h) - - Thanks to Alan Stweart <Axs2@osi.com> for reporting - this! - -Mon Aug 26 00:34:05 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Updated all of ACE such that the ACE_GUARD* macros now all take - the name of the ACE_*Guard* that they will use as the scoped - locking object. This is important for several reasons: - - 1. It make it more clear what is going on in the code, rather - than hiding behind the macros! - - 2. It is now possible to have multiple ACE_GUARD* macros in the - same scope by calling each scoped locking object a different - name. This is used in the Local_Tokens.cpp file. - - * ace/Synch.h (ACE_Null_Mutex_Guard): Added the locked() method so - that this signature will conform to the one expected of - ACE_Guard. - - * tests: Added a new file Test_Future.cpp, which tests the new ACE - Futures mechanism using Active Obejcts. Thanks to Andres Kruse - <kruse@cern.ch> for contributing this test. - - * ace: Added three new files: Future.{h,cpp}, - Method_Object.{h,cpp}, and Activation_Queue.{h,cpp}, which - implement Polymorphic Futures. Thanks to Andres Kruse - <kruse@cern.ch> for contributing these. - - * ace/Stream.cpp (dump): Replaced LM_INFO with LM_DEBUG. - -Sun Aug 25 21:57:57 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Rather than using operator new directly, most of ACE now - uses the ACE_NEW and ACE_NEW_RETURN macros. For instance, - rather than writing: - - if (token_manager_ == 0) - token_manager_ = new ACE_Token_Manager; - - we should write: - - if (token_manager_ == 0) - ACE_NEW_RETURN (token_manager_, ACE_Token_Manager, 0); - - The reason for this is that it makes it much easier to ensure - that all dynamic memory allocation errors are treated uniformly. - I've updated the entire ACE library code tonight to make this - usage consistent whenever possible. - -Sat Aug 24 11:51:38 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Time_Value.h: Simplified various things so that the nasty - macros necessary to build DLLs on Win32 will be simplier. In - addition, I will only #include <sys/time.h> for those platforms - that don't already do this in <time.h> (i.e., if - ACE_NEEDS_SYSTIME_H is defined in config.h). Please let me know - if you run across any platforms like this. - - * ace/TLI_{Connector,Acceptor}: Added two additional parameters at - the end of the connect() and accept() methods, respectively, so - that the ACE TLI wrappers can be used with X.25. Thanks to Ajit - Sagar <asagar@spdmail.spd.dsccc.com> for suggesting this fix. - - * ace: Integrated Eric Newton's XtReactor into the Makefile. If - you want to include this into ACE, make sure to define - ACE_HAS_XT in the config.h file. - - * examples/Misc: Integrated the XtReactor tests. - - * ace/OS.i (getservbyname,gethostby*): Fixed a suble omission -- - any calls to socket function should be wrapped by the - ACE_SOCKCALL_RETURN macro in order to make the errnos work - correctly on Win32. - - * ace/OS: Added support for the getprotoby{name,number} wrappers. - Thanks to Joe DeAngelis <bytor@faxint.com> for suggesting this. - - * ace/Connector.cpp: Fixed a subtle bug in the ACE_Connector. - The problem centered around the following line in - cleanup_AST(): - - if (this->handler_map_.find (handle, ast) == -1) - - This lookup always failed because the key, the handle of the - service handler, was always -1. The service handler's handle is - not set until a successful connection is made and connector - transfers ownership of the handle to the service handler. The - fix for this is to store the ACE_HANDLE in the ACE_Svc_Tuple - *separately* from the ACE_Svc_Handler. Thanks to Bill Gerecke - <gerecke@rayva.org> for being so persistent in tracking this - down. - - * ace/ARGV.cpp (ACE_ARGV): Added a nifty new constructor that - converts argv-style vectors of strings into a single string - (this is the reverse of what the original constructor does!). - - * ace/ACE: Added a new utility method called strecpy(), which - copies <t> to <s>, returning a pointer to the end of the copied - region (rather than the beginning, a la <strcpy>. - -Thu Aug 22 15:43:58 1996 <harrison@samba.cs.wustl.edu> - - * ace/OS.h: Changed the interface of ACE_OS::fork_exec (char - *const argv[]). (There is no longer a separate const char *path - parameter. Now, argv[0] must be the full path name to the - executable. - - * tests/Time_Service_Test.cpp: Updated the Time Service - one-button test to use the new ACE_OS::fork_exec. I didn't - event break it. - - * tests/Tokens_Test.cpp: Updated the Tokens one-button test to - use the new ACE_OS::fork_exec. It actually works now. - - * tests/test_config.h: Added some more #defines to help simplify - path differences between NT and UNIX. Perhaps these should be - moved into OS.h? - -Thu Aug 22 13:46:58 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Thread_Manager.cpp (ACE_Thread_Control): The status_ member - in ACE_Thread_Control() was not being initialized! This caused - Purify to complain loudly about invalid memory accesses. I have - added an initialiser to ACE_Thread_Control::ACE_Thread_Control - to set status_ to 0. Thanks to Ross Dargahi <rossd@krinfo.com> - for reporting this. - - * ChangeLog: The ACE configuration files "config-irix*.h" defined - 'ACE_HAS_SIGINFO' to indicate that IRIX supports SVR4 extended - signals. This should be 'ACE_HAS_SIGINFO_T' instead. Thanks to - Craig Johnston <johnston@tortilla.ds.boeing.com> for reporting - this. - -Wed Aug 21 21:09:01 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Time_Value.h: Added an extra condition, #if defined - (ACE_BUILD_DLL) so that ACE_Svc_Export evaluates to - something. Previously, it was evaluating to nothing in some - files such as Naming_Context.cpp where we were doing #define - ACE_BUILD_DLL and not #define ACE_BUILD_SVC_DLL. - -Wed Aug 21 00:33:17 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/ACE.cpp (format_hexdump): Fixed a minor bug in - format_hexdump(). If the buffer to dump is a multiple of 16 it - prints an extra blank line. ALso fixed the code to use spaces - rather than tabs and put an extra space between the first 8 HEX - bytes and the second. Thanks to Luca Priorelli - <lucapri@mbox.vol.it> for this code. - - * ace/Log_Msg.h (ACE_HEX_DUMP): Added a new logging macro: - - #define ACE_HEX_DUMP(X) \ - do { int __ace_error = errno; \ - ACE_Log_Msg *ace___ = ACE_Log_Msg::instance (); \ - ace___->set (__FILE__, __LINE__, 0, errno, ace___->restart (), - ace___->msg_ostream ()); \ ace___->log_hexdump X; \ - } while (0) - - which makes it possible to dump info in HEX. Thanks to Luca - Priorelli <lucapri@mbox.vol.it> for suggesting this. - - * ace/config-win32-msvc4.0.h: Added - - #define _WINSOCKAPI_ - - To avoid multiple inclusions. Thanks to Luca Priorelli - <lucapri@mbox.vol.it> for suggesting this. - - * ace/OS.h: enclosed the #define of WIN32_LEAN_AND_MEAN macro - definition between #ifndef ... #endif to avoid compiler - warnings. Thanks to Luca Priorelli <lucapri@mbox.vol.it> for - suggesting this. - - * ace/SOCK.cpp (win32_fini): Fixed a potential problem in ACE - where any code of the form: - - ACE_DEBUG ((LM_DEBUG, "%d", GetLastError())); - - will reset errno a couple of times before GetLastError() gets - called. So the result is always 0. The fix is to say: - - int ret = GetLastError(); - ACE_DEBUG ((LM_DEBUG, "%d", ret)); - - Thanks to Luca Priorelli <lucapri@mbox.vol.it> for noticing - this. - - * ace/Connector.cpp (create_AST): Was missing a return 0; if we - successfully register a cancellation id. Thanks to William - L. Gerecke <gerecke@rayva.org> for reporting this bug. - - * ace/Module.h: Added a non-existent friend class to get ACE - to stop complaining - - private: - friend class ACE_Shutup_GPlusPlus; // Turn off g++ warning - ~ACE_Module (void); - // *Must* use dynamic allocation. - - Thanks to Eric Newton for the suggestion. - - * ace/Svc_Conf.y (ace_create_service_type): Removed some stray - calls to ACE_ERROR that were left over from earlier - configurations of ACE. Thanks to Gonzalo Diethelm - <gonzo@ing.puc.cl> for reporting this. - - * ace/Log_Msg.cpp (instance): Fixed the #ifdefs so that - ACE_MT_SAFE implies ACE_HAS_THREAD_SPECIFIC_STORAGE. Thanks to - Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting the need for - this. - -Tue Aug 20 13:09:55 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * INET_Addr.cpp, line 84: Irix's C++ is not able to determine - whether to use the set(u_short,ACE_UINT32,int) or the - set(u_short,const char [],int), since on Irix, INADDR_ANY is 0. - I cast the value so that the call would read set(port, - ACE_UINT32(INADDR_ANY)) and everything went fine. Thanks to - Gonzalo Diethelm <gonzo@ing.puc.cl> for reporting this. - - * ace/Synch[_T]: Added a new wait() method that takes a first - parameter which is the mutex used to serialize access to the - condition. This is useful if you want to store the - ACE_Condition object in shared memory (in which case, the use of - a reference to mutex_t doesn't work!). Thanks to Mark Patton - <mark_patton@ftw.paging.mot.com> for recommending this approach. - - * ace/Task.h: Added a forward template declaration for - ACE_Task_Exit so that it will compile on HP/UX. Thanks to Tim - Ottinger <tottinge@csci.csc.com> for pointing this out. - - * ace: changed line 19 of ace/Str_Buf.h from - - #include "OS.h" - - to: - - #include "ace/OS.h" - - Fixed similar problems with OS.h at line 1154 and Dump.h at line - 150. Thanks to Alan Stewart <axs2@osi.com> for reporting this. - -Tue Aug 20 20:18:49 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * tests/TSS_Test.cpp (main): Fixed a small typo. I was referencing - the wrong variable but didn't catch it since it was in the #if - !defined (ACE_HAS_THREADS) section. Fixed the typo and also - renamed the variable called big_count to iterations. Thanks to - Tim Ottinger <tottinge@csci.csc.com> for pointing this out. - -Mon Aug 19 19:25:50 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * {examples,apps,tests}: Removed the use of zerop from these - files, as well... - - * ace/{Acceptor.cpp,Name_Proxy.cpp,Token.i}: Removed the use of - zerop from these files, as well... - - * ace/Connector.cpp (connect_svc_handler): It looks like our good - friend ACE_Time_Value::zerop isn't getting initialized correctly - on Win32. Therefore, I've replaced it with a direct use of - &ACE_Time_Value::zero. - - * ace/Time_Value.cpp: Removed the static pointer variable "zerop" - since there was no guarantee it was getting intialized before it - is used! Instead of using ACE_Time_Value::zerop, use - &ACE_Time_Value::zero. Thanks to William L. Gerecke - <gerecke@rayva.org> for reporting this problem. - - * ace/OS: Added zillions of changes to make ACE compile with OSF/1 - and its DCE threads implementation. Thanks to Martin Schoeckle - <schoeckle@ike.uni-stuttgart.de> for sending these. - - * ace/config-osf1-3.2.h: Updated this file with fixes for OSF/1 by - Martin Schoeckle <schoeckle@ike.uni-stuttgart.de>. - - * ace/ACE.cpp (handle_timed_complete): Added new logic to - ACE::handle_timed_complete() so that it sets errno to - ECONNREFUSED if the connection is refused by the server. When - you issue an asynchronous connect request, to complete it, you - will use complete() with a timeout. However, complete can fail, - and then it will deallocate any resource, (i.e. close down the - socket handle), also for timeout expiration. So, a user - interested in retrying to complete a connection while the - timeout expires will not use complete(); but rather will use - handle_timed_complete(). In fact, using handle_timed_complete() - the user could detect the reason of a failure (by examining - errno) and decide how to proceed. In the old ACE version the - problem was that, if handle_timed_complete() failed because of - the recv() returning 0, errno remained unchanged and so its - value could be quite misleading with respect to the reasons of - the failure. Thanks to Antonio Tortorici - <antonio@rh0011.roma.tlsoft.it> for this fix and the explanation - above. - - * ace/OS.h: Added support for Borland 5.0's uint64. Thanks to - Hani Yakan <hani@i-online.com> for suggesting the strategy to - accomplish this. - -Mon Aug 19 15:52:07 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * tests: Added new macros to the test_config.h file in order to - simplify the testing. - -Mon Aug 19 00:21:22 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Re-released version 4.0.28 for testing (will change the version - number after Tim gives me the new Token stuff). - - * {netsvcs/lib,tests/test_config.h}: Removed spurious dependencies - on fstream.h and iostream.h. Thanks to Alan Stewart - <axs2@osi.com> for reporting this. - -Sat Aug 17 17:25:49 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Reactor: Removed the use of "inline" in the Reactor.cpp - files because this was causing problems with some - compilers/linkers. Thanks to Gonzalo Diethelm - <gonzo@ing.puc.cl> for recommending this. - - * examples/Misc/test_XtReactor1.cpp: Added a new test of the - XtReactor, courtesy of Eric Newton <ecn@clark.net>. - - * ace/config-hpux-10.x.h: According to Eugene K. Plaude - <jec@r-style.msk.su>, HP-UX 10.01 supports user-level threads - based on the pthreads interface specified by POSIX in 1003.4a, - Draft 4 (which is basically DCE threads). Therefore, I've - enabled the ACE_HAS_DCETHREADS symbol in the config-hpux-10.x.h - configuration file. If this isn't correct, please let me know. - -Sat Aug 17 02:18:39 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * examples/Tokens/manual/README: Added a new Token example - application. The manual test gives users a text-based - interactive interface to local or remote tokens. This is - extremely useful for manually testing the token server and - setting up deadlock scenarios. See the README file for more - details. - - * examples/Tokens/deadlock/README: Updated the deadlock example - application to test the new deadlock detection algorithm for - readers/writer locks. I also added the use of Token Invariants - to ensure correctness of the mutexes and readers/writer locks. - See the README file for more details. - -Fri Aug 16 22:16:05 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * ace/Token_Manager.cpp: Updated all Token code to use - ACE_OS::last_error instead of errno. - -Fri Aug 16 00:03:24 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * After a long hiatus, released version 4.0.28 for testing. - -Thu Aug 15 21:04:35 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * man: Updated all the ACE manual pages and html pages to reflect - recent changes. - - * netsvcs/lib/Server_Logging_Handler.cpp: Fixed an omitted - "ACE_BUILD_SVC_DLL" that was causing linker errors on NT. - Thanks to Luca Priorelli <lucapri@mbox.vol.it> for reporting - this. - - * examples/Log_Msg/test_log_msg.cpp: Added a test for the new - log_hexdump() function. - - * ace/Log_Msg.cpp (log_hexdump): Integrated the log_hexdump() code - into the ACE Log_Msg abstraction. Thanks to Luca Priorelli - <lucapri@mbox.vol.it> for fixing this and for Todd Montgomery - for originally supplying the code. - - * ace/Signal.cpp (ACE_Sig_Handlers): Moved the #endif /* HPUX */ - down to the end of the file so that it works correctly on HPUX. - Thanks to Eric C. Newton <ecn@clark.net> for report this bug. - - - * ace/OS.i: Updated the behavior of thr_join() so that it will do - a ::CloseHandle after getting the exit status. Thanks to the - ever vigilant James Mansion - (mansionj@lonnds.ml.com) for noticing this. - - * examples: Finally added Tim and Prashant's examles/OS directory, - which contains a test that illustrates a "portable" means to - spawn processes on NT and UNIX. - - * ace/Malloc_T.cpp (next): Added an overloaded next() method that - returns the name that is bound to the pointer in the - Malloc_Iterator. This is useful in order to differentiate - entries in the pool based on their name. Thanks to Kim Gillies - <gillies@noao.edu> for suggesting this. - - * ace: Changed all uses of thread_t, thread_key_t, mutex_t, - rwlock_t, sema_t, cond_t, etc. to ACE_* in order to avoid - polluting the name space. Also switched from using macros to - using typedefs whereever possible. Thanks to Gonzalo Diethelm - <gonzo@ing.puc.cl> for recommending this. - - * ace/System_Time.cpp: Added template specializations for - templates used in the ACE_System_Time class. This should solve - some nasty undefined templates problems with GCC... Thanks to - Joseph DeAngelis <bytor@faxint.com> for pointing out the - problem. - - * ace/Name_Space.cpp: Fixed the file Name_Space.cpp as follows: - - // Name_Space.cpp - #define ACE_BUILD_DLL - //#include "Name_Space.h" - #include "ace/Name_Space.h" - - Thanks to Eugene K. Plaude <jec@r-style.msk.su> for fixing this! - - * ace/config-hpux-10.x.h: Added support for TLI since according to - Eugene K. Plaude <jec@r-style.msk.su> this should work. If not, - please let me know. - -Wed Aug 14 21:29:46 1996 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> - - * examples/Reactor/Logger: rearranged the Logger directory so it - would be more clear what the client and server programs did and - how to run them. - - * examples: Merged the contents of the SVR4 examples directory - into the IPC_SAP/SOCK_SAP directory so that we can remove the - SVR4 directory altogether (it wasn't contributing much...). - - * examples: Removed the vestigal Win32 tests since ACE now runs on - Win32 and we don't need a separate test directory. - - * netsvcs/client: Renamed the file remaining file in this - directory to logging_app.cpp since I moved the other file to the - examples/Reactor/Logger directory. - - * ace/Reactor.cpp (check_handles): If eh->get_handle() returns -1 - the select() code will index the [-1] element of an array. To - fix this, I've added a check of the value returned from - eh->get_handle(). Thanks to Eric C. Newton <ecn@clark.net> for - reporting this. - - * ace/OS.i (sema_wait): Fixed a subtle bug in the Pthreads - wrappers that surfaced on the SGI IRIX 6.2 port. There was some - code that looked like this: - - pthread_cleanup_push(); - int result = 0; - ... - pthread_cleanup_pop(); - return result; - - However, on Irix 6.2, the push introduces a new scope that is - closed by the pop, so result goes out of scope before returning. - Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for pointing this - out. - - * ace/OS.h: Changed the definition of pthread_mutex_t and - pthread_cond_t to mutex_t and cond_t to be consistent with other - usage in ACE. Thanks to Gonzalo Diethelm <gonzo@ing.puc.cl> for - pointing this out. - -Wed Aug 14 01:25:47 1996 <harrison@samba.cs.wustl.edu> - - * ace/SPIPE_Acceptor.cpp: Added the PIPE_TYPE_MESSAGE | - PIPE_READMODE_MESSAGE flags to CreateNamedPipe pipe options so - that data is received in messages rather than as a stream. This - is consistent with the behavior of the SPIPE_Connector. When we - have time, we need to extend the interface so that stream pipes - are also supported, as well. - - * SPIPE_Acceptor.cpp: Made the ACE SPIPE in and out buffer sizes - 10 k. The previous size was just 512 bytes. This larger buffer - size helps decrease flow control. - -Tue Aug 13 23:21:46 1996 <harrison@samba.cs.wustl.edu> - - * examples/Connection/blocking: Updated the blocking SPIPE example - application to use a pool of threads in the proactor to handle - incoming client messages. The SPIPE-acceptor example - illustrates how named pipes are used on NT. Once the server - establishes a connection to a single client, it spawns a thread - pool to handle incoming requests via the proactor event - loop. That is, a separate thread from the pool is used to - process each message sent by a client. The size of the thread - pool can be specified by command-line arguments. This example - leverages the queueing performed by the NT kernel to trivially - implement a thread pool architecture. See - examples/Connection/blocking/README for more details. - - * Service_Config.h: Added a <thread> parameter (with a default - size of 0) to the proactor accessor method. This allows - applications to specify the size of the thread pool that can - block on Proactor::handle_events. - -Tue Aug 13 02:30:58 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Task: Added a new public interface called thr_count(). This - returns a count of the number of threads running within a Task. - If the value returned is 0, then the Task is a Passive Object. - If the value returns is > 0 the task is an Active Object, and - the value is a count of the number of threads running within the - object at this snapshot of time. - - * ace/OS: I implemented Karlheinz's suggested optimizations for - the ACE condition variable implementation under Win32. Here's - the deal... The original implementation used an internal_mutex - to ensure that access to the count of the number of waiters was - serialized between the waiter and signaler threads. The new - implementation is designed so that only the waiter threads - access the waiter count. Therefore, we can utilize the - external_mutex to serialize access to this, thus eliminating the - need for the internal_mutex. However, this means that code - *must* be written using the standard condition variable idiom, - i.e., - - int resources () - { - external_mutex.acquire (); - - // ... - - cond.signal (); - external_mutex.release (); - } - - Rather than like this: - - int resources () - { - external_mutex.acquire (); - - // ... - - external_mutex.release (); - cond.signal (); - } - - which is what some thread programming books recommend as an - optimization. However, you should be careful not to use this - form since it can lead to "lost wakeup" bugs caused by the fact - that the implementation of ACE_OS::cond_signal will test if the - waiter count > 0 *without holding any locks*!!! - - Fortunately, ensuring this shouldn't be a problem since most ACE - code uses the following idiom: - - int resources () - { - ACE_Guard mon (external_mutex); - - // ... - - cond.signal (); - // Destructor of mon releases external_mutex. - } - - Clearly, there are subtle tradeoffs between performance and - programmability here... - - * ace/Synch: Updated all of the ACE semaphore wrappers to take the - new "max" value as their final constructor argument. - - * ace/OS: Added a new default argument to the end of the - sema_init() method. This allows us to specify the maximum value - of the semaphore (this is only important on NT). Currently, it - is hard-coded to 0x7fffffff in uses. The new approach makes it - possible to set the max to a different value. Thanks to - Karlheinz for requesting this. - - * ace/Message_Queue.cpp: Added an implementation of the dump(). - Thanks Karlheinz. - - * ace/Synch.cpp: Added an implementation of the dump() method. - Thanks Karlheinz. - - * ace: Updated all usage of ACE_Thread_Mutex_Guard so that it now - uses the ACE_GUARD* macros correctly. Thanks to Chris Eich - <Chris_Eich@optilink.optilink.dsccc.com> for pointing out the - need for this. - - * examples/Threads: Added Karlheinz's new test_barrier2.cpp test - program that makes sure that the ACE_Message_Queues are working - correctly when accessed by multiple threads. - - * netsvcs/lib/Server_Logging_Handler.cpp (handle_logging_record): - Fixed an errant use of ACE_Guard, which wasn't properly checking - of the Guard acquired the lock. Thanks to Chris Eich - <Chris_Eich@optilink.optilink.dsccc.com> for pointing this out. - - * ace/OS.h (ACE_GUARD): Added default "ace_mon" implementations of - type ACE_Null_Mutex even in cases where there's no threading - defined so that code accessing ace_mon.release() and - ace_mon.acquire() will compile correctly. - - * apps/Gateway/Gateway/Channel.h: Fixed the code so - that we don't try to use TLI if the platform doesn't support it - (instead, we'll use sockets). Thanks to Marius Kjeldahl - <marius@funcom.no> for reporting this problem. - - * examples/ASX/Event_Server/{Supplier,Consumer}: Fixed the code so - that we don't try to use TLI if the platform doesn't support it - (instead, we'll use sockets). Thanks to Marius Kjeldahl - <marius@funcom.no> for reporting this problem. - -Mon Aug 12 14:50:47 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * examples/Misc: Added Eric Newton's <ecn@clark.net> test case for - his XtReactor integration. - - * ace: Included Eric Newton's <ecn@clark.net> code that integrates - ACE with the Xt event loop. This still needs a bit of work - (e.g., making it thread-safe and incorporating signal support), so - I haven't added it to the Makefile yet. If someone can take the - time to fix it up, I'll be happy to integrate it into ACE. - - * ace/Message_Queue.cpp (dequeue_head): Fixed the mother of all - bugs in the ACE_Message_Queue implementation... The problem was - that I was trying to be too clever by optimizing the number of - Condition::signal() calls by only calling signal() when the - queue changed state from empty to non-empty (or full to - non-full). It turns out that this optimization works fine for a - single producer/consumer case, but fails when there are multiple - consumers. The fix was just to call signal() every time. This - should be ok because the underlying Condition variable - implementation will perform the optimization in the correct - fashion. Thanks to the omniscient Karlheinz for detecting this - problem and reporting it. - -Sun Aug 11 15:52:07 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * tests: Made minor changes to test_config.h, SPIPE_Test.cpp, and - UPIPE_SAP_Test.cpp to accomodate the change made to SPIPE_Addr. - SPIPE_Addr now accepts a string of the form [host:]port and then - creates the rendezvous point. Originally, SPIPE_Addr would - assume that the string being passed in was the actual rendezvous - point. - -Sat Aug 10 18:41:21 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * netsvcs/lib/Logger.cpp (init): Added a new service to netsvcs - called ACE_Logger which allows us to control the output of all - the services. The ACE_Logger service can be invoked with - different flags (such as STDERR|OSTREAM) which in turn sets - ACE_Log_Msg to direct the output of all the services to the - appropriate stream(s). Note that if a service needs to stay - unaffected from ACE_Logger, it should be invoked before - ACE_Logger gets invoked. Also note that like other services in - netsvcs, ACE_Logger can also be dynamically linked in. - -Sat Aug 10 14:23:07 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added Steve Huston's <shuston@ultranet.com> patches to get ACE - to compile on UnixWare 2.01. This mostly involved changes to - the internal types used by the socket wrappers. Thanks Steve! - -Fri Aug 9 01:34:19 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * examples/ASX/UPIPE_Event_Server/Options.cpp (print_results): - Added a typedef to avoid problems if a platform doesn't support - prusage_t. Thanks to Marius Kjeldahl <marius@funcom.com> for - reporting this. - - * include/makeinclude/platform_linux_pthread.GNU. The line that - say: - - LIBS = -lpthreads -lstdc++ - - was modified to say: - - LIBS += -lpthreads -lstdc++ - - Thanks to Marius Kjeldahl <marius@funcom.com> for reporting - this. - -Fri Aug 9 18:26:16 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Local_Name_Space.cpp (reset): Fixed a subtle (yet very - annoying bug). In switching contexts a test program would hang - after a certain number of switches. Having gone through the code - thoroughly and with the aid of Purify, the bug was narrowed down - to an extraneous delete taking place in - ACE_Name_Space::reset(). Essentially, we do not need to delete - ACE_Name_Space_Map::instance() which is actually the - SHARED_MALLOC since it gets deleted in the destructor of - ACE_Local_Name_Space. - -Thu Aug 8 17:55:20 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/SPIPE_Addr.cpp (set): Implemented - ACE_SPIPE_Addr::string_to_addr(). Modified ACE_SPIPE_Addr::set() - using code provided by Brad Flood to create the rendezvous - point. Note that originally ACE_SPIPE_Addr constructor and set() - would take the actual rendezvous point but now they rely on - being passed a string which is of the format "[host]:port" - (where host is optional). The rendezvous point is then created - by extracting from the string the hostname (if any) and also - using the port number as the unique pipe name. Note that this - approach works on both UNIX and Win32. - -Mon Aug 5 20:15:59 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/OS.i (last_error): Fixed a typo. In the set and get methods - last_error(), there should be a check for "if defined - (ACE_WIN32)" and not "if defined (ACE_HAS_WIN32)" - -Wed Aug 7 00:21:42 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Log_Msg.h: Replaced all uses of errno *following calls to - ACE_Log_Msg::instance()* so that we first cache errno in a local - variable called __ace_errno. We need to do this because - ACE_Log_Msg::instance() can reset errno == 0. Thanks to - Tim for pointing this out. - -Mon Aug 5 20:15:59 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/OS.i (last_error): Fixed a typo. In the set and get methods - last_error(), there should be a check for - "if defined (ACE_WIN32)" and not "if defined (ACE_HAS_WIN32)" - -Sat Aug 3 14:52:32 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * examples/Win32/win32_client.cpp: Changed ACE_GUARD_RETURN to - ACE_GUARD in the method Errno::flags since the return type is - void. - - * examples/Connection/non_blocking/CPP-connector.cpp: Made some - minor changes to get things compiling on Win32. The call to - handle_close now takes zero as the first argument (which is - never used). Also the arguments to ACE_SERVER_ADDRESS are now - swapped (hostname followed by port number) to be consistent with - the change made to the macro. Thanks to Brad Flood for - suggesting these changes. - - * examples/Connection/non_blocking/CPP-acceptor.cpp: Made minor - changes to some of the methods to make sure all control paths - return a value. Also changed the default port number to - ACE_DEFAULT_SERVER_PORT_STR to match what the connector tries to - connect to. Thanks to Brad Flood <BFLOOD@slc.unisysgsg.com> for - suggesting these changes. - - * ace/OS.h (ACE_SERVER_ADDRESS): Modified the macro - ACE_SERVER_ADDRESS so that it creates a string of a server - address with a "host:port" format. Previously the order was - reversed. Thanks to Brad Flood for suggesting this change. - -Sat Aug 3 00:07:26 1996 Douglas C. Schmidt (schmidt@lambada.cs.wustl.edu) - - * ace: Fixed problems with recursive tracing of ACE_TRACE by - commenting out certain constructors in IPC_SAP.cpp, - FIFO_Send_Msg.cpp, FIFO_Send.cpp, and FIFO.cpp. Thanks to - Karlheinz for finding and reporting these fixes. - -Fri Aug 2 22:19:05 1996 Douglas C. Schmidt (schmidt@lambada.cs.wustl.edu) - - * ace/ACE.cpp (format_hexdump): Fixed an infamous "off by one" bug - that was causing this to fail on Win32 (time to switch to Java? ;-)). - Thanks to lucapri@mbox.vol.it for finding this. - -Thu Aug 1 14:08:30 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/CORBA_Handler.cpp (activate_service): Fixed a typo caused by - an omitted ENDTRY. Thanks to Garrett Conaty - <gconaty@outbackinc.com> for noticing this. - -Mon Jul 29 10:03:16 1996 Douglas C. Schmidt (schmidt@lambada.cs.wustl.edu) - - * examples/Win32/win32_client.cpp: There was a typo in one of the - ACE_GUARD macros. Thanks to Tim Ottinger - <tottinge@csci.csc.com> for pointing this out. - -Mon Jul 22 12:41:22 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Local_Name_Space.cpp (reset): Added a new method - ACE_Name_Space_Map::reset() which deletes the instance of - ACE_Name_Space_Map. This forces instance() to create a new - instance using a new context file in the case of the context - having changed. I make use of this in - ACE_Local_Name_Space::create_manager(). - -Fri Jul 19 12:28:07 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/System_Time.cpp (get_master_system_time): Modified - ACE_System_Time::get_master_system_time() so that if an entry - for the time is not found in shared memory (indicating that no - Clerk is running), then we should just return the local time of - the host. - - * netsvcs/lib/TS_Clerk_Handler.cpp (update_time): Modified - ACE_TS_Clerk_Handler::update_time() so that if the Clerk is not - connected to any servers, is sets the delta time to zero - allowing clients to then use the local time of the host. - -Wed Jul 17 22:19:53 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/UPIPE_Connector.cpp (connect): Added an #ifdef around the - check of ACE_OS::isastream (handle) in - ACE_UPIPE_Connector::connect() since the call is not supported - on NT. - -Thu Jul 11 22:22:57 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * ace/OS.i (kill): Modified ACE_OS::kill so that it works on NT. - It takes a process ID, creates a handle for the associated - process, and calls TerminateProcess on the handle. This is - actually pretty dangerous according to the NT documentation. - Can majorly confuse DLLs. Does the same old thing on UNIX. - - * ace/OS.cpp (fork_exec): Added a fork_exec operation to ACE_OS. - This works on UNIX and NT. It combines the forking and exec'ing - into one call. This has to be combined since Win32 - CreateProcess only starts applications from scratch (unlike UNIX - fork). - - * examples/OS/test_os.cpp: Added a new example application to test - the new ACE_OS::fork_exec and ACE_OS::kill operations. - -Tue Jul 9 13:04:14 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Service_Manager.cpp (reconfigure_services): To improve - portability on Win32 and UNIX I replaced the use of a signal to - trigger reconfiguration to instead make a call to the new - ACE_service_Config::reconfig_occurred() method. This should - actually perform the same as the original approach, since all - the signal handler ever did was to set this flag! Thanks to - Karlheinz for pointing out the need for this. - - * ace/Service_Config.h: Added a new static public method called - reconfig_occurred(sig_atomic_t) to set if a reconfiguration - should take place the next time through the event loop. - -Mon Jul 8 14:20:01 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Time_Value.h: Added "ACE_Export" before all global operators - to allow them to be dll-exportable on NT. - -Mon Jul 8 13:12:05 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/{Message_Block,DEV_IO,SPIPE_Stream}.cpp: Fixed several more - cases of delete array that should have been delete [] array. - Thanks to Tom Leith for pointing out some of these. I can hear - the ghost of James Mansion coming closer... ;-) - - * INSTALL: Added tips on how to install ACE on a Win32 platform - that lacks a network card. - - * ChangeLog: Split ChangeLog-96 into two files (ChangeLog-96a and - ChangeLog-96b) since it was becoming quite large! Thanks to - Chris Lahey for pointing this out. - - * ace/Stream.cpp: Was missing a "return 0;" at the end of the - close() method. Thanks to Tom Leith <trl@icon-stl.net> for - finding this. - -Mon Jul 8 14:20:01 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Time_Value.h: Added "ACE_Export" before all global operators - to allow them to be exportable from Win32 DLLs. - -Sun Jul 7 10:34:48 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.27 for testing. - - * config-sunos5.5*.h: Removed all uses of ACE_HAS_SVR4_SIGNAL_T in - the config files since Solaris 2.5 has consistent signal and - sigaction types (at last!). - - * Installed and compiled ACE successfully with the new SunC++ 4.1 - compiler on Solaris 2.5. However, there seems to be major - problems with the interaction of the SunC++ exception handling - runtime system and the Solaris multi-threading mechanisms. This - is causing the ACE multi-threading tests to bomb with - segmentation faults inside of the _ex_unwind() library function. - If you read the /opt/SUNWspro_3.1/READMEs/c++ file you'll see - why this problem is occurring (apparently due to bugs in the - Solaris libC.so.5 C++ runtime library). - - There seem to be two fixes for this problem: - - 1. Add the following to *all* threads (including main): - - #include <exception.h> - - void *my_thread_entry_point (void *) { - set_terminate (abort); - set_unexpected (abort); - - // Do real work... - } - - This is the approach recommended by the README file in - SUNWspro_3.1. However, it is *clearly* a horrible hack and - very non-portable (therefore, I deem it worthy of Microsoft - ;-)). - - 2. Compile ACE (and applications?) with -noex in order to avoid - this bug. This is clearly not desirable either since it - precludes the use of exception handling with C++ and threads - on Solaris... - - Since ACE doesn't use exceptions internally on Solaris option 2 - seems like the best approach for the time being. When Sun gets - it act together and releases a bug-free library and C++ - software, I'll fix ACE accordingly. - - * tests: Integrated the latest of Prashant's "one-button" tests - into the main ACE release. These will run on both UNIX and - Win32 now. - - * ace/UPIPE_Stream.cpp (recv): Changed the semantics of the - ACE_UPIPE_Stream::recv (char *, size_t, ACE_Time_Value *) - method. Currently, the behavior is to block until *exactly* N - bytes are read. However, this is incorrect for 2 reasons: - - 1. It makes it hard to write a server that doesn't know - precisely how big the messages are from the client. In - particular, if the receiver doesn't know how big the buffer - messages are from the client it will block indefinitely! - - 2. It is redundant with respect to the - ACE_UPIPE_Stream::recv_n(), which also blocks until all N - bytes are received. - - Therefore, I've made the new UPIPE_Stream::recv() method block - only until it's received the first block of data that allows it - to fulfill its size request, or anything that is smaller than - that size. - - * ace/OS.cpp (thr_create): Since POSIX pthreads doesn't provide an - equivalent of THR_NEW_LWP in the pthreads_attr_* functions, I've - added an emulation that should work for Solaris. Basically, if - THR_NEW_LWP is set when ACE_OS::thr_create() is called, we use - the ACE_OS::thr_{get,set}concurrency methods to increase the - number of LWPs by one. - - * ace/Message_Block: Changed the default high water mark for an - ACE_Message_Queue from 4K to 16K. This is useful since it - allows applications to buffer more information before blocking. - - * ace/Log_Msg: Added a pair of operations that allow applications - to acquire and release the synchronization lock used internally - by the ACE_Log_Msg implementation. This allows applications to - hold the lock atomically over a number of calls to ACE_Log_Msg, - which is useful for composite operations like the following: - - // Make sure the following operations are run atomically! - ACE_LOG_MSG->acquire (); - - while (c != '!') - { - if (c_stream.recv (&c, 1) == -1) - ACE_DEBUG ((LM_DEBUG, - "(%t) buffer recv from supplier failed\n")); - else - ACE_DEBUG ((LM_DEBUG, "%c", c)); - } - - ACE_LOG_MSG->release (); - - * examples/IPC_SAP/UPIPE_SAP: Revised all of the UPIPE_Stream - tests to make them more consistent and correct with respect to - the new changes. - - * ace/Stream.cpp (link_i): There was a bug in the link_i() logic - because we weren't also linking the other stream back to our - stream. - - * ace/UPIPE_{Acceptor,Connector}: Modified both of these classes - so that they don't - - * ace/Stream.cpp (close): Modified close() so that it now detects - "double-closes" and ignores anything but the first one. - - * ace/UPIPE_Stream: Updated this class so that it no longer - inherits from ACE_Stream (previously ACE_UPIPE_Stream had - inherited from *both* ACE_Stream *and* ACE_SPIPE). There are - several reasons we shouldn't inherit from ACE_Stream: - - 1. There are operations on ACE_Stream that don't make any sense - on ACE_UPIPE_Stream (e.g., link(), unlink()). - - 2. ACE_Stream isn't really designed to be subclassed (e.g., - it doesn't have virtual methods). - - 3. Not inheriting makes the interface cleaner, e.g., we now use - send() and recv() methods consistently, rather than - send_msg()/put() and recv_msg()/get(). - - 4. The return values from the I/O methods are now more - consistent than they were before. - - * ace/Message_Block: The signature for the copy() method was - incorrect. It should have been copy (const char *, .....) - rather than copy (char *, ....). - - * examples/IPC_SAP/UPIPE_SAP: Together with Prashant, fixed up the - ACE_UPIPE_Stream tests so they more cleverly - (and correctly) utilize and illustrate various ACE concurrency - features. - -Sat Jul 6 18:28:55 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Stream.cpp: Fixed some obscure bugs with Stream::unlink() - and Stream::link(). These bugs were triggered by the - ACE_UPIPE_Stream tests. We need to make sure that we don't have - race conditions in the order in which ACE_UPIPE_Stream close() - down. Prashant and I fixed this problem by (1) adding a lock to - unlink() and link() and then creating unlink_i() and link_i() to - perform the work and (2) being more careful about trying to - unlink our side and the other side of a linked Stream. - - * ace/config-linux.h: According to Istvan Buki - <istvan.buki@infoboard.be>, Linux now supports the - send_msg()/recv_msg() system calls, as well as UNIX domain - sockets. Therefore, I've updated the config-linux*.h file to - remove the existing restrictions. If this turns out not to be - the case, please let me know. - - * ace/LSOCK.cpp (recv_handle): Added a change to some casts to - make ACE compile with Linux. Thanks to Istvan Buki - <istvan.buki@infoboard.be> for reporting this. - - * apps/Gateway/Gateway/File_Parser.cpp (readword): Removed - yet another use of: - - for (int x; foo(x); ) - { - } - - x = 10; - - Which is now a deprecated feature of C++. - - * include/makeinclude: added the -lw library to the GNU G++ - platform*.GNU file in order to pick up the wide-character string - functions. - -Fri Jul 5 18:11:44 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Re-released version 4.0.26 for testing. - - * ace/CORBA_Handler.cpp (activate_service): Revised the code to - use the Orbix macros for TRY/CATCH rather than try/catch. We - need this to make legacy code work! Thanks to Irfan for - pointing this out. - - * ace/Thread_Manager: Fixed a bunch of typos that grelims snuck - in. Thanks to Jack Erickson <jack@cibc.com> for reporting this. - - * examples/IPC_SAP/TLI_SAP/ftp-server.cpp: Fixed some typos that - were causing problems on AIX. Thanks to Greg Wilson - <gvwilson@vnet.ibm.com> for reporting this. - - * examples/Reactor/Misc/test_time_value.cpp (operator<<): Added a - "const" in front of the ACE_Time_Value & in order to make things - work correctly on AIX. Thanks to Greg Wilson - <gvwilson@vnet.ibm.com> for reporting this. - - * ace/SPIPE_Acceptor: Fixed some missing "returns" that had sprung - up in the #else arm of the SPIPE code. Thanks to Greg Wilson - <gvwilson@vnet.ibm.com> for reporting this. - - * apps/Synch-Benchmarks/Benchmark: Fixed a typo that was causing - the application to fail to compile on AIX. Thanks to Greg - Wilson <gvwilson@vnet.ibm.com> for reporting this. - - * Changed all uses of virtual int init (int, char **) to virtual - int init (int, char *[]) to workaround bugs with MSVC++... - - * ace/OS.h: for POSIX pthreads, changed the definition of the - THR_SCOPE_SYSTEM macro so that it has the same value as - THR_BOUND. If this isn't done, then things don't quite work - right when we implement the ACE_OS::thr_create() wrapper. - -Thu Jul 4 13:17:35 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Thread_Manager: Added a new method called thr_self() that - *does* return a real handle that can be used by - WaitForMultipleObjects, etc. Note that this new approach - cleverly caches this handle in TSS in order to cut down on - search time. Thanks to Jesper for pointing this technique out. - - * ace/OS.i (thr_self): After receiving comments from Jesper, undid - the earlier change today that was returning a duplicated handle - for ACE_OS::thr_self(). It turns out this is a bad idea because - the handle most typically doesn't get released, which leads to - handle leaks. - - * ace/Thread_Manager: Added a new private method called - check_state(). This method extends existing code to be smarter - about how we check to see what "state" (e.g., suspended, - cancelled, etc.) a thread is in. The original code - (which was a macro called ACE_CHECK_STATE) didn't behave - correctly if we asked about the state of a thread that was - different from ourselves! - - * ace/Thread: Modified the public interface to - ACE_Thread::spawn_n() so that it now takes a void *stack[] and - size_t stack_size[]. If stack != 0 it is assumed to be an array - of n pointers to the base of the stacks to use for the threads - being spawned. Likewise, if stack_size != 0 it is assumed to be - an array of n values indicating how big each of the - corresponding stacks are. This is useful since now we can spawn - a group of threads each of which has its own custom stack and/or - stack size. Thanks to Ashish Singhai - <singhai@delirius.cs.uiuc.edu> for pointing out the need for - this. - - * apps/Synch-Benchmarks: Updated the Synch benchmarks so that most - of them work again. The trick is *not* to use ACE_OS::sleep () - (which doesn't seem to be thread-friendly...) but instead to use - ACE_OS::select() as a timer. - - * man: updated the manual pages and html pages to reflect all the - recent changes. - - * ace/Malloc_T.cpp (open): Added a check to make sure that if - init_acquire() fails we don't let this go by undetected... - Thanks to Karlheinz for pointing out the need for this. - - * ace/OS.i (thr_getconcurrency): Fixed a subtle bug with the - ACE_OS::thr_getconcurrency() function. I was mistakenly using - ACE_ADAPT_RETVAL for the result of ::thr_getconcurrency(), which - is clearly wrong! - - * ace/Service_Record.cpp (remove): Fixed a typo that was causing - the removals of Modules in a dynamically configured Stream to go - into infinite loops. - - * ace/OS.i (thr_self): Modified the ACE_OS::thr_self (hthread_t &) - function so that it will return a *duplicate* of the current - thread's pseudo-handle returned by GetCurrentThread(). This - change is necessary because the pseudo-handle returned by - GetCurrentThread() is pretty useless (e.g., it can't be used by - any other thread to "wait" for this thread to exit). This new - behavior is used in the examples/Reactor/ReactorEx test program. - - * ace/Service_Config.cpp: I'd forgotten to assign the - delete_svc_rep_ flag when dynamically allocating the svc_rep_. - This is fixed now. - -Wed Jul 3 20:09:44 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added a new subdirectory called $WRAPPER_ROOT/tests that - contains the first phase of the ACE regression tests. - - * ace/Reactor.cpp (check_handles): Fixed an earlier fix with the - ACE_Reactor::wait_for_multiple_events() method. The earlier fix - had changed the exit condition of do/while loop to be - - while (nfound == -1 && this->handle_error () >= 0); - - However, this was causing signal handling to break... - Therefore, the right fix is to keep the exit test as: - - while (nfound == -1 && this->handle_error () > 0); - - and instead fix handle_errors() so that it returns 1 if we're - able to fix a bad handle... Thanks to Prashant and Irfan for - tracking this down. - - * ace/OS: Finally broken down and added a new pair of ACE_OS - functions called "last_error()". These basically call - SetLastError/GetLastError on Win32 or they set/get errno on - UNIX. - - * ace/config-linux.h: Fixed an annoying problem with - struct msghdr in Linux by adding - - #define msg_accrights msg_control - #define msg_accrightslen msg_controllen - - to the config-linux*.h files. Thanks to Michael R"uger - <m_rueger@syscomp.de> for suggesting this. - - * ace/SOCK_IO.cpp (recv): Fixed a "bug" where - ACE_SOCK_IO::{send,recv} allocates with: - - iovec *iovp = new iovec[total_tuples]; - - But deletes with: - - delete iovp; - - Thanks to the ever vigilant James Mansion - (mansionj@lonnds.ml.com) for noticing this. - -Tue Jul 2 23:48:38 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * ace/Service_Config.h: Added ReactorEx to the singleton resources - that the Service_Configurator holds. This includes accessors, - destruction hooks, and event loop methods. - - * examples/Reactor/ReactorEx/README: There is a new example - application for the ReactorEx. Please check out - examples/Reactor/ReactorEx/README for details. - -Tue Jul 2 18:43:12 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 4.0.25 for testing. - - * examples/ASX/Message_Queue/priority_buffer.cpp: Added a new test - program that illustrates the use of the new Message_Queue - priority scheme. - - * ace/Message_Queue: Added new support for prioritized message - enqueueing into the ACE_Message_Queue. Now, when an application - uses ACE_Message_Queue::enqueue() the new Message_Block is - inserted into the queue according to its msg_priority(). When - dequeue_head() is used the item retrieved will then be the item - of "highest priority" (priorities range from 0 to MAX_LONG). - Note that the semantics of the existing enqueue methods, - enqueue_head() and enqueue_tail(), remain unchanged. - - * ace/Message_Block: Changed the type of the priority in a message - block to u_long rather than u_char. This gives us a much - greater range of priorities! - -Mon Jul 1 01:12:08 1996 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Thread.h: Changed a couple of mistyped comments. Thanks - to the eagle eyes of Andres Kruse for noticing this. - - * ace/OS: added more comprehensive support for UNICODE to - both the Win32 and UNIX OS adaptation layer. This new - support automagically selects the appropriate implementation - (i.e., either char * or wchar_t *) for the string comparison - routines (which are used in places like ACE_Mem_Map). - - * ace/Service_Config: Split up the ACE_Service_Config::close() - method into two parts: close_svcs() and close_singletons(). - This makes it possible to remove svc.conf services without - destroying Singletons like the Proactor, Reactor, etc. Thanks - to Karlheinz for recommending this. - - * ace/Service_Config: Added flags for remembering who created the - Singleton Proactor, Allocator, Thread_Manager, and - Service_Repository (in addition to the Reactor, which I did last - week). If we created these Singletons, then we are responsible - for freeing them up. Thanks to Karlheinz for pointing out the - need for this. - -Mon Jul 1 16:26:27 1996 Prashant Jain (pjain@merengue.cs.wustl.edu) - - * ace/Connector.cpp: Added two new arguments to connect () namely, - "int flags" and "int perms". The Connector can now pass these - two arguments to its template arguments (e.g., SOCK_Connector, - SPIPE_Connector, etc.) when calling their connect() method. A - consequence of doing this was that we had to modify the - signature of the connect() method on some of the IPC_SAP classes - (e.g., TLI_Connector, SOCK_Connector, and LSOCK_Connector). - Note that these changes may break some existing code, - particularly with TLI_Connector (see below), so beware... - - * ace/TLI_Connector.cpp: Changed the order of the connect() - arguments to be more consistent with the rest of the IPC_SAP - classes used with the Connector. Please note that existing - examples which use TLI_Connector may need to be modified as a - result of this change. - - * ace/OS.i (open): Modified ACE_OS::open() to use the argument - perms to turn the flag FILE_FLAG_OVERLAPPED on and off for - Win32. - - * ace/Service_Config.cpp (end_proactor_event_loop): Added new - methods run_proactor_event_loop() and end_proactor_event_loop() - which call handle_events on the Proactor. - -Mon Jul 1 02:15:34 1996 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * ace/Proactor.h: Made ACE_Proactor an ACE_Event_Handler so that - it can be registered with the ACE_ReactorEx. ACE_Proactor - associates the same global HANDLE with every overlapped I/O - operation. This global HANDLE can be registered with the - ACE_ReactorEx. Therefore, by using the - ACE_Proactor::handle_signal method as an adapter, we can now - dispatch overlapped I/O and other "waitable" objects from a one - ACE_ReactorEx running in a single thread of control. Thanks to - James Mansion <mansionj@lonnds.ml.com> for setting us on the - right path! - - * ace/ReactorEx.h: Added a ACE_ReactorEx to encapsulate Win32 - WaitForMultipleObjects(). The ACE_ReactorEx handle_events() - method calls ACE_Event_Handler::handle_signal when the - corresponding Win32 HANDLE becomes signaled. This gives us a - uniform abstraction for dispatching all "waitable" objects on - Win32, including events related to I/O completion ports and - events related to other forms of NT synchronization (such as - mutexes, semaphores, threads, etc.). - - * ace/Timer_Queue.h (calculate_timeout): Added a calculate_timeout - method to ACE_Timer_Queue. Also removed the same method from - ACE_Reactor. This is so Reactor, ReactorEx, and Proactor can - all reuse the calculations required by the Timer_Queue without - duplicating code. - |
