Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS (mmap): Added a new parameter to the argument list for - mmap(). This parameter is an ACE_HANDLE * and is used in the - Win32 implementation, which requires CreateFileMapping to open a - new HANDLE. This handle is passed back to the caller, which is - then responsible for freeing it... I'll probably need to modify - the ACE_Mem_Map class to manage this new handle for the WIN32 - version. - - * ace: Updated all the SPIPE files in preparation to porting them - to Windows NT, where they will be implemented using Win32 Named - Pipes! - - * ace/Typed_SV_Message: Fixed a mysterious braino where the method - definitions for Typed_SV_Message were actually within - Typed_SV_Message_Queue.cpp. I'm not sure why this happened, but - it's clearly been this way for eons... Also, changed the name - of the method "max" to "max_size" to avoid conflicts with macros - on Windows NT... - - * ace: Added a new config symbol: ACE_HAS_SYSV_IPC. If this is - *not* set (e.g., Win32) then don't try to compile any of the - System V IPC mechanisms (e.g., shared memory, message queues, - semaphores). - - * ace/Malloc: Reimplemented the Malloc-family to factor out common - code. Also added a new method called "trybind" which atomically - tries to bind a new void *pointer to a char *name. If there is - no name with the same value, the bind succeeds. Otherwise, the - bind "fails", but returns the existing pointer. - - * ace/Map_Manager: Reimplemented the Map_Manager to factor out - common code. Also added a new method called "trybind" which - atomically tries to bind a new int_id to an ext_id. If there is - no ext_id with the same name, the bind succeeds. Otherwise, the - bind "fails", but returns the existing int_id. - - * ace/Memory_Pool.cpp: Commented out all the diagnostic messages - in the various ACE_*_Memory_Pools. Now that we're actually - using this within ACE, they were distracting. - - * ace/CORBA_Handler.cpp (ACE_ST_CORBA_Handler): Gave iterations_ - an initial value of "5" for backwards compatibility. Thanks to - Irfan for doing this. - - * ace/Map_Manager.cpp (ACE_Map_Manager): Fixed some more braino in - the constructors of Map_Manager. During the recent changes I'd - forgotten to initialize the Map_Manager's instance variables to - 0. Thanks to Irfan for finding this out the hard way... ;-) - - * ace/OS.i (gettimeofday): Added a WIN32 implementation of - gettimeofday. This is pretty nasty, but it should centralize - all of this processing in one place in ACE! - -Sat Dec 30 00:50:20 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/Timer_Queue: Removed the current_time() method from the - Timer_Queue class. All uses will be replaced with calls to - ACE_OS::gettimeofday(). Not only does this factor out more - code, but it is also reentrant! - - * ace/ACE.cpp (handle_timed_accept): Consolidated code so that - select() is always used, rather than poll(). - - * ace: Generalized the ACE file locking wrappers (both at the - Synch-level and the ACE_OS class level) to enable them to lock - arbitrary regions (aka "records") of a file. Before, they could - only lock the entire file (which remains the default behavior). - This new behavior works for both NT and UNIX. - - * ace/Synch: Removed the definition and use of the - ACE_SYNCH_ERROR_RETURN macro from all the ACE Synch* methods. - This behavior has been integrated into the ACE_OS class instead - since it cleans up lots of code that would otherwise have been - hard to write. - - * ace/INET_Addr.cpp (get_host_name): Fixed a bug that arose by - trying to use the reentrant version of gethostbyaddr all the - time. In order to fix this, I've added a new get_host_name() - method that allows the caller to supply a buffer for the - hostname. - - * ace: Cleaned up all the POSIX_TIMER junk that permeated ACE. - Now all platforms will have the POSIX timer structures (e.g., - timestruc_t and timespec), though only those that actually - support nano-second timing will be able to do anything useful - with this... As part of this cleanup, the poll, select, and - cond_timedwait method in ACE_OS now take ACE_Time_Value * rather - than int, timeval *, and timestruc_t, respectively. This - *greatly* cleans up the clutter throughout the rest of ACE. - - * ace/ACE: Added two new methods called tv2msec and msec2tv that - converts ACE_Time_Value format into millisecond format and vice - versa. This will make it easier to port code between NT and - UNIX. - - * ace/Reactor: Removed the code in the Reactor that previously - allowed it to be resized after it had been initialized. This - code no longer was used due to the recent enhancements that - ensure the Reactor is only initialized once per-process. - - * ace/Reactor: Modified the Reactor so that it now compiles on NT. - It doesn't work yet, but at least it compiles! - - * ace/Reactor: Moved the "max3" method from the Reactor to OS.h, - where it has become a template function usable throughout ACE. - - * ace/OS.cpp: Added extern "C" before the NT implementations of - readv() and writev(). - - * ace/OS.i: Fixed the declaration of ::readv() and ::writev() for - cases where the OS doesn't provide them natively. - - * ace/Event_Handler: Modified handle_signal() to take an int - rather than an ACE_HANDLE. The old way broke under NT... - - * ace: Made lots of minor changes to resolve signed int - vs. unsigned int mismatches. Thanks to the MSVC++ 4.0 compiler - for pointing these out. At least it's good for - something... ;-). - -Fri Dec 29 15:01:10 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/ACE.cpp (handle_timed_accept): Reimplemented the core - select() loop to make the code portable to Win32. - - * ace/Map_Manager.cpp (ACE_Map_Manager): Fixed a minor bug caused - by recent changes (forgot to initialize max_size_ in the - constructor...). - - * Updated all the manual pages to reflect the latest changes. - - * ace/ACE.cpp: Fixed up the ACE class so that all of the methods - should compile on both Windows NT and UNIX! - - * ace/OS: Moved the get_file_size() method from class ACE and put - it into class ACE_OS, where it's been renamed to filesize(). - This is really more of an "OS" function, e.g., it's supported on - Win32 directly. - - * ace/OS.cpp: added readv() and writev() implementations for those - platforms (e.g., Windows NT) that require them. - - * ace/Makefile: Added a new regex to the Svc_Conf_l.cpp target - that will substitute <stdio> for <unistd>. This should solve a - portability problem with Windows NT... - - * ace/Malloc: Modified the sync() and protect() methods to use - void * rather than char *. This is now consistent with the OS - classes. - - * ace/OS: Changed things so that all the mmap() related OS - wrappers use void * in their external interface. Any - discrepancies between platforms are now dealt with internally, - in the implementation of the methods. Thanks to Chris Lahey - (clahey@ix.netcom.com) for suggesting this. - - * ace/Local_Name_Space: Modified how ACE_NS_String is used to - instantiate ACE_Map_Manager in order to work around problems - with AIX C++. Thanks to Chris Lahey (clahey@ix.netcom.com) for - reporting this. - - * ace/Synch.i: Added a definition for ACE_RW_Mutex::acquire(). - -Fri Dec 29 00:34:16 1995 Chris Lahey (clahey@ix.netcom.com) - - * ace/OS.h: Changed the #ifdef for ACE_HAS_COMPLEX_LOCKS to - ACE_HAS_COMPLEX_LOCK. - - Changed prototypes for ACE_OS:mprotect(), msync(), and munmap() - to accept ACE_MMAP_TYPE for their first arg. The AIX versions - of these calls all expect void * for their pointer variable. - Note that madvise() takes a caddr_t for its 1st arg and - therefore does not need to be altered. (See related changes in - OS.i and Mem_Map.i) - - Changed prototype for ACE_OS::getsockname(), arg3 to int * (See - related change in OS.i) - - Changed prototype for ACE_OS::setsockopt(), arg4 to const char * - and arg 5 to int (See related change in OS.i) - - * ace/OS.i: Changed function definition for ACE_OS::mprotect(), - msync(), and munmap() to accept ACE_MMAP_TYPE as their 1st arg. - - The following changes relate to the inconsistencies in the - sockets calls on AIX. I thought it would make more sense to - leave the public interfaces alone and then handle the - differences internally. That way it won't break any exisiting - code. - - Changed function definition for ACE_OS::getsockname() to accept - arg3 as int *. Made similar changes in ACE_OS::setsockopt() - - change definition to accept const char * for arg4 and int for - arg5. Add the following code at the start of the function: - Also made changes to ACE_OS::recvfrom() - change arg 6 back so it is - int *. - - * ace/Mem_Map.i: In ACE_Mem_Map::advise(), cast 1st arg to - ACE_OS:madvise() to (caddr_t). - - * ace/Memory_Pool.cpp: In ACE_MMAP_Memory_Pool::acquire(), make - cast to char * in the return statement. In - ACE_MMAP_Memory_Pool::handle_signal(), also make same cast in - the ACE_DEBUG statement near the top of the function. - - * ace/Reactor.cpp and ace/Reactor.h: ACE_Reactor::handler_i() - doesn't return properly if *eh != 0. Remove last "else" so - function always returns 0 if handler != 0. - - In ACE_Reactor::owner(), we need to change signature since - thread_t is not an integer. This has been changed to int - ACE_Reactor::owner(thread_t *t_id); The last two lines have been - changed to: *t_id = this->owner_; return 0; - - * ace/Synch.cpp: In ACE_Condition_Mutex::wait(), the call to - cond_timedwait() does not exist, but ACE_OS::cond_timedwait() - does exist. It takes the same arguments. - - * ace/Synch.h and ace/Synch_T.h: At the end of both files, before - the #define INLINE check for this define's existence to avoid - causing compilers to choke. - - * ace/Mem_Map.i: In ACE_Mem_Map::operator(), the return statement - looked very odd. In the assignment to addr, why is the ", 0" in - the statement? - -Fri Dec 29 00:34:16 1995 Douglas C. Schmidt (schmidt@lambada.cs.wustl.edu) - - * ace: Fixed up many minor problems with the various types of - Shared_Memory wrappers. This mostly entailed changing from char - * to void * to be more consistent with the other parts of ACE. - In addition, I now only include the *.i files if __INLINE__ is - enabled. - - * ace/Memory_Pool.cpp (map_file): Fixed a minor bug by enabling - MAP_FIXED if we're trying to map a file using a fixed address. - -Thu Dec 28 18:39:16 1995 Douglas C. Schmidt (schmidt@merengue.cs.wustl.edu) - - * ace/Local_Name_Space.cpp: Finished implementing changes to the - ACE_Malloc stuff and the Local_Name_Space that Irfan had begun - last semester. - - * ace/SString.cpp: Added new optimizations to the assignment - operators of the ACE_[WCS]String classes to avoid - freeing/allocating memory if the current size is large enough. - - * ace/SString: Added copy constructors... - - * ace/Local_Name_Space.cpp: Modified the implementation of bind() - to avoid a race condition. - - * ace/Map_Manager.cpp (bind): Changed the semantics of bind() so - that callers can control whether or not INT_IDs are reassigned. - Also changed things so that callers can get back the existing - value if they choose not to reassign. - - * ace/SString.cpp: Removed the "P" (persistent) versions of all - these classes and merged them into the default versions. The - persistence is now determined by the type of allocator passed in - as a parameter to the constructor (or by using the "default" - allocator that is accessible via - ACE_Service_Config::allocator()). - - * ace/Map_Manager.cpp: Removed the "P" (persistent) versions of - all these classes and merged them into the default versions. - The persistence is now determined by the type of allocator - passed in as a parameter to the constructor (or by using the - "default" allocator that is accessible via - ACE_Service_Config::allocator()). - - * ace/Malloc_T: Modified the bind() algorithm so that it will - allow the caller to determine whether duplicates are allowed or - not... Also changed things so that callers can get back the - existing value if they choose not to allow duplicates. Irfan - questions the sanity of this... ;-) - - * ace/Synch: To be consistent, added acquire_write and - acquire_read methods to ACE_Mutex. These are useful for cases - where we are going to be parameterizing classes like ACE_Malloc - with some type of mutex wrapper (e.g., ACE_RW_Mutex, ACE_Mutex). - - * ace/Malloc_T.cpp (calloc): Added a new method called "calloc" - that will not only allocate the memory dynamically, but will - also give it an initial value (e.g., '\0'). - -Thu Dec 28 01:10:43 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.i: Modified the implementation of the TLI methods so that - they are conditionally compiled away if the platform doesn't - support TLI... Thanks to Neil Cohen for pointing out the need - for this... - - * ace/OS.i: Modified the implementation of dlopen() and dlsym() to - account for limitations with SunOS 4.x... - - * ace/Service_Repository.cpp: Modified this class to use the - ACE_OS::dlclose method. - - * ace/Parse_Node.cpp: Modified this class to use the - ACE_OS::dlopen and ACE_OS::dlsym methods. - -Wed Dec 27 23:25:03 1995 Jesper S. M|ller (stophph@diku.dk) - - * Added appropriate flags in OS.h for successful inclusion of - several header files, such as Malloc.h and friends. Also added - mprotect to ACE_OS for Win32 to avoid linker errors. - - * Added a return value (from map_file) to - ACE_MMAP_Memory_Pool::handle_signal. The compiler was - complaining. Likewise on - ACE_MMAP_Memory_Pool::commit_backing_store (there 0 seemed like - the correct off-the-end return value). - - * Removed include of some SV semaphore file, if not needed in - Malloc.h. Worse for Memory_Pool.h, since the SV_Semaphore - wrappers consistently differ completely from the other - synchronization routines. I guess we'll need some variant of - ACE_Process_Semaphore that takes an integer as a key instead of - a string, and does not perform automatic init/destroy. - - * Also upgraded fd's from int to ACE_HANDLEs and changes -1 to - ACE_INVALID_HANDLE where appropriate. - - * By help of aggresive preprocessor conditionals, made Handle_Set - work with Win32. There is a fd_set abstraction with appropriate - FD_xxx macros for WinSock, and it requires no sync'ing. The - Handle_Set_Iterator should also work. The good looks of - Handle_Set was impaired, though. Right now, the trigger is the - ACE_WIN32 flag, although it should be something like - ACE_FD_SET_USES_BITS for the unix approach, or like - ACE_FD_SET_USES_VECTOR for the WinSock approach. - - * Reactor almost compiles now, but not quite: Handlers are - addressed by fd, this is no longer possible - what a mess - we - need to step through the handle indices somehow. This will - likely get into some nasty quadratic complexities when iterating - the handles to find the event_handler for each file - handle. Mabye we can circumvent this with a hash table lookup - for those opaque handles. - - * There was a problem with the Svc_Conf.l.cpp and the - Svc_Conf.y.cpp and the extremely lame MSVC++ 2.0. I had to - rename them to Svc_Conf_y.cpp, etc. Awful! - - * Added code to inquire the 'host' name for Win32 in the ACE_Client_Id - class. Another candidate for ACE_OS. - - * About 60 or so ACE .cpp files compile now, which reminds me that - I'll be working on some precompiled header scheme soon, since it - takes for ever and ever, even on my 32meg system with pretty - good SCSI drives. Mabye it's because I'm only running a 66MHz - i486 DX2 (yawn). - - * Dozens of other changes have been made to various files, all - pertaining to int vs. ACE_HANDLE. In Service_Manager.h, a signal - number was an ACE_HANDLE, but just close by, some fd's were - ints. Fixed that, too. - -Sat Dec 23 14:15:16 1995 Jesper S. M|ller (stophph@diku.dk) - - * I've also grouped the .i and .cpp functions by class, - and #if'ed the sbrk and SysV pools out, since - Win32 cannot support those. - - * Added 'inline' to day accessor functions in Date_Time. - - * Two things that missed me in Trace.cpp: - 1) The inclusion order was so that I couldn't - build Trace.o, since it didn't know the MALLOC_HOOK thing. - I moved the #include of Trace.h down below that of ACE.h. - 2) The declaration and definition of the ACE_Trace constructor - differed by a const, which I added. - 3) When linking, multiple symbols were found for some - OS calls like mutex_init, corresponding to the larger - OS Win32 functions. I has ACE_INLINED_OS_CALLS off, - so sometimes the OS functions were inlined, sometimes - not. - I disabled the inline hack in Trace.cpp for WIN32 for now. - This seemed to resolve matters. - - * There was a major problem in OS.i, where Synch.h was needed for - mutex support (in conjunction with TSS info linked list). I - chose to make thr_keycreate and some others non-inlined. - - * More 'is-it-a-handle-or-success' confusion in SOCK*.* Changed - ACE_SOCK_Dgram to use int status. Changed ACE_SOCK_CODgram to - use int status. Changed ACE_LSOCK to use int status. Also - changed a few derived classes - -Fri Dec 22 14:03:15 1995 Douglas C. Schmidt (schmidt@lambada.cs.wustl.edu) - - * ace/OS.h: Added a new type for rwlock_t for platforms that don't - support threading... Thanks to Neil Cohen for reporting this. - - * ace: Merged in all of Jesper's changes for NT and Chris Lahey's - changes for AIX. - - * ace: Merged tli.h into OS.h to avoid name conflicts on Win32. - - * Fixed duplicated names where case is the only difference. - ace/thread.cpp - ace/Thread.cpp - ace/TLI.h - ace/tli.h - apps/Token_Server/mutex_example/simple_token_client.cpp - apps/Token_Server/mutex_example/Simple_Token_Client.cpp - apps/Token_Server/script_example/scripting_token_client.cpp - apps/Token_Server/script_example/Scripting_Token_Client.cpp - tests/IPC_SAP/SOCK_SAP/FD-client.cpp - tests/IPC_SAP/SOCK_SAP/fd-client.cpp - tests/IPC_SAP/SOCK_SAP/FD-server.cpp - tests/IPC_SAP/SOCK_SAP/fd-server.cpp - -Wed Dec 20 22:26:24 1995 Jesper S. M|ller (stophph@diku.dk) - - * FIFO.cpp: One last comparison of 'open' return status where and - ACE_INVALID_HANDLE should be changed to -1. - - * One more last wrong comparison in FIFO_Recv_Msg.cpp. - (Never say never again!) - - * Put an appropriate conditional around the inclusion of - Handle_Set.h for ACE_WIN32 (for now). - - * Introduced a few backslashes in the macros of Dump.h that were - somehow left out... Had to add a really stupid constructor for - struct Tuple. I haven't a clue why MSVC++ wants this! Replaced - 'return ACE_ODB;' with 'return ACE_ODB::instance_;' in the - Singleton access function. - - * Added a constructor for ACE_ODB. It may be private, but it still - needs to be defined... - - * Stack and Set compiles fine for Win32 (not surprisingly) - - * If'ed out the guts of ACE_IPC_SAP enable/disable calls for - Win32, since async IO doesn't work that way on there. - - * Event_Handler now uses ACE_INVALID_HANDLE for default args. - - * SOCK compiles except for the ACE_SOCKET <> ACE_HANDLE - problem. Refer to issue #3 above. - - * We're swamping the ace directory with .mak files. I used the - winntace.mak file, which is compilable and linkable. - -Thu Dec 21 15:37:42 1995 Douglas C. Schmidt (schmidt@merengue.cs.wustl.edu) - - * ace: Greatly simplified the include files so that (1) compilers - are faster and (2) the ACE_Trace mechanism works correctly. - - * ace/Trace: Modified the ACE_Trace_TSS class so that it is no - longer a template. This was overkill since we know the type - head of time (i.e., ACE_Trace_State). - - * ace: Added a number of new changes to ACE to make things work on - AIX. Thanks to Chris Lahey <clahey@ix.netcom.com> for these - changes. - - * ace/Thread_Manager.cpp: Removed the get_max_thr_id() method - since it was not portable to NT or POSIX pthreads. Nothing in - ACE depended on it anyway... - - * ace/OS: Added a new static data member called NULL_thread that - is a "zero'd" out thread id. This is necessary to deal with the - POSIX pthread implementation of a thread id, which is not always - implemented as a number... By using this new approach, all the - special-case code in Synch.cpp disappears... - - * ace/OS: Added a new method to class ACE_OS called thr_equal() - that masks the differences between comparing thread ids using - the threading libraries. This simplifies the code in Synch.cpp - and Reactor.cpp. - - * ace: Updated all uses of mmap() to use the new ACE_MMAP_TYPE - typedef. This deals with the fact that different versions of - UNIX define mmap() inconsistently (e.g., some use void * and - some use char *...). - - * ace: Removed testconfig.h and merged all of those #defines into - OS.h. This centralizes changes in one place and also eliminates - the need for ./apps and ./tests to include extraneous files... - - * ace/testconfig.h: Changed all uses of 0666 to ACE_DEFAULT_PERMS. - Also, removed all PERMS enums and substituted ACE_DEFAULT_PERMS - instead. - -Wed Dec 20 17:29:55 1995 Tim H. Harrison (harrison@merengue.cs.wustl.edu) - - * Rewrote the Token deadlock detection algorithm. It now performs - "best-effort" detection of deadlock for remote acquires and - complete deadlock detection for local acquires. - -Wed Dec 20 02:37:39 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace/OS.h: The select() system call has its own include file on - AIX: <sys/select.h>. We can wrap the #include with a variable - #if defined (ACE_HAS_SELECT_H). - - * include/makeinclude/platform_aix.GNU: Added new support for AIX. - Thanks to Chris Lahey <clahey@ix.netcom.com> for these changes. - Added a number of other minor changes, as well. - - * ace: Made a bunch of minor changes to get ACE to compile on - SunOS4.x, Linux, and SGI. - - * ace/config-linux.h: added ACE_HAS_MSG (thanks to Neil Cohen - for this). - - * ace/OS.h: Conditionally compile for ACE_HAS_UTIME for - <sys/utime.h>. - - * Released an alpha version of ACE containing the new Windows NT - port. - - * Integrated and tested all the new Windows NT changes in class - ACE_OS, as well as the Synch* and Threads* classes. We're now - able to build Jesper's win32_test.cpp file in ./ace! A complete - NT port should be just around the corner... - -Tue Dec 19 17:59:04 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * ace: Move the remaining contents of sysincludes.h into ACE.h. - There is no more sysincludes.h (at long last!). - - * ace: Rearranged things so that the OS.[hi] files contain all the - OS-specific #defines and #includes that were previously in - sysincludes.h. - - * ace: Renamed the ACE_Misc class to class ACE, which is more - representative of what it does. - - * INSTALL: updated the installation instructions to explain how - the new directory structure works. Thanks to Neil Cohen for - pointing out the discrepancy beteen the source and the - documentation ;-). - - * Reorganized (by flattening) the ACE library directory structure - to make it work for both Windows NT and UNIX. Note that Windows - NT does not have symbolic links, so the old way of doing things - didn't port... The consequences of these changes is there is - now a single directory called $WRAPPER_ROOT/ace that contains - the *.[hi] and *.cpp source files. This is also where the - libACE.a and libACE.so libraries are built by default. Also, - note that the suffix used by ACE has been changed from *.C to - *.cpp to deal with the lame Visual C++ compiler... - -Tue Dec 19 01:26:54 1995 Douglas C. Schmidt (schmidt@merengue.cs.wustl.edu) - - * tests/ASX/Event_Server/Event_Server/Supplier_Router.cpp (put): - Fixed up a problem with the Event_Server. Somewhere along the - way it stopped being concurrent! The new version fixes this. - Thanks to Alex V Maclinvosky <alexm@teltrunk1.tait.co.nz> for - noticing this... - - * Added a billion new changes to class OS to integrate the Windows - NT port with the rest of ACE. We are getting very close... - -Mon Dec 18 12:45:13 1995 Jesper S. Møller (stophph@diku.dk) - - * Major problems in the IPC_SAP. First, I detected that some open - calls returned handles, some returned -1 or 0. For instance - ACE_SOCK has a constructor, that calls this->open and expects a - handle (which it even sets as the current handle - value!). Unfortunately, the return from open is either 0 or -1, - depending on how well the open went. ACE_HANDLE being - typedef'ed to a void* really reveals some problems! I have - solved the problem for the FIFO*.* family and for SOCK.* - -Mon Dec 18 12:43:46 1995 Douglas C. Schmidt (schmidt@merengue.cs.wustl.edu) - - * tests/Reactor/CODgram/CODgram.C (main): Fixed a bug in main() - caused by initializing the Reactor twice. Thanks to Aurelio - Nocerino <aurelio@irsipcs2-27-le0.irsip.na.cnr.it> for reporting - this. - - * libsrc/Service_Configurator/Service_Config.C Added a new - constructor to ACE_Service_Config that can be used to initialize - internal variables without performing a full configuration. - -Mon Dec 18 01:22:22 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Service_Config: renamed tokens.h to sc_tokens.h to avoid - file name collision on Win32. Thanks to Jesper S. M|ller - <stophph@diku.dk> for reporting this. - - * tests/Mem_Map/IO_Test: renamed io_test.C to test_io.C to avoid - file name collision on Win32. Thanks to Jesper S. M|ller - <stophph@diku.dk> for reporting this. - - * libsrc/Misc/OS: Implemented condition variables for Windows NT. - -Sun Dec 17 21:23:32 1995 Douglas C. Schmidt (schmidt@merengue.cs.wustl.edu) - - * libsrc/Misc/Trace: Fixed up the ACE_Trace class so that it - doesn't include any calls that will improperly trigger infinite - recursion! This allows the ACE library to be traced completely. - -Sat Dec 16 19:12:37 1995 Jesper S. Møller (stophph@diku.dk) - - * Changes to OS.*: - * Added conditionals to the OS.h for Win32, for the special ACE/Win32 - thr_destroy_tss(), which is automatic for Solaris. - * Changed declarations of thr_create, thr_suspend, thr_continue, - thr_join and thr_[gs]etprio to use hthread_t instead of thread_t. - * Changed return type of OS::open from int to ACE_HANDLE. - * Provided non-obtrusive handling of thr_handle in OS::thr_create - for non-Win32. - * Copied ACE::writev to OS::writev for Win32. Something similar - should happen for other systems... - - * Changes to Thread.*: - * Changed join, suspend and continue to take handles. - * Added thread handle return address to spawn. - - * Changes to Thread_Manager.*: - * Added thread handles to the Thread_Descriptor structure. - * Modified insert_thr and append_thr functions to also take - handles. - * Made ACE_Thread_Descriptor::Thread_State (a enum) public - so Thread_Manager::append_thr could use it as a formal - parameter (I suspect this is a bug in MSVC++). - * Changes the various flavours of suspend, continue, etc. to - use handles instead of id's. Keep in mind that none of this - is destructive for Unix, but vital for Win32. - * There is still a problem with ACE_Thread_Control registering - itself with the Thread_Manager - the thread does not have means - of finding it's own handle. In this particular case, we could - have the thread duplicate it's pseudohandle into a real one, - and pass that one along. I'd really, really, really rather not - have to maintain a thread id->handle mapping myself; It would - slow down thread manipulation and give some troublesome memory - overhead. - - * Changes to Log_Msg.*: - * OS::getpid instead of ::getpid. - - * Changes to Misc.*: - * Sections inappropriate for Win32 #if'd out... - * Provided naive timestamp function (No date) for Win32. - - * Changes to IPC_SAP.*: - * Uses OS::ioctl instead of ::ioctl - * Uses ACE_INVALID_HANDLE instead of ACE::INVALID_HANDLE - - * Changes to FIFO.*, : - * Uses ACE_INVALID_HANDLE instead of ACE::INVALID_HANDLE - - * Changes to FIFO_Send.*: - * open now returns an int insted of an ACE_HANDLE. - * Uses ACE_INVALID_HANDLE instead of ACE::INVALID_HANDLE - - * Changes to FIFO_Send_Msg.*: - * open now returns an int insted of an ACE_HANDLE. - * Uses ACE_INVALID_HANDLE instead of ACE::INVALID_HANDLE - * Uses OS::writev instead of ::writev - - * Changes to FIFO_Recv.*: - * open now returns an int insted of an ACE_HANDLE. - * Uses ACE_INVALID_HANDLE instead of ACE::INVALID_HANDLE - - * Changes to FIFO_Recv_Msg.*: - * open now returns an int insted of an ACE_HANDLE. - * Uses ACE_INVALID_HANDLE instead of ACE::INVALID_HANDLE - - * Changes to sysincludes.h: - * Uses ACE_INVALID_HANDLE instead of ACE::INVALID_HANDLE - -Sat Dec 16 12:29:06 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/Addr/INET_Addr.C: Changed the implementation so - that the reentrant versions of the library calls are always used - (class OS sorts this all out). This reduces the amount of - clutter in the code. - - * libsrc/Threads/Synch: Added a new implementation of - "readers/writer" locks for both Windows NT and POSIX pthreads. - By default, these threads packages don't have this feature. - - * libsrc/Threads/Synch: Added a new macro called - ACE_SYNCH_ERROR_RETURN that greatly simplifies the definition of - the synchronization wrappers. - - * include/ace/sysincludes.h: Removed the pthreads_map.h file and - integrated this into sysincludes.h. - -Fri Dec 15 02:39:25 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Misc/OS.i: Finished updating class OS so that it will - compile correctly for OS platforms that don't support threads, - as well as platforms that support POSIX Pthreads vs. Solaris - threads, etc. - - * libsrc/Misc/OS: integrated Jesper S. M|ller <stophph@diku.dk> - support for POSIX regular expressions (e.g., compile() and - step()) and sysinfo() into ACE. - - * Integrated and tested all of Irfan's changes to ACE to support - the new persistence Name_Server. This added some new classes in - various places that use the ACE_Allocator. - -Thu Dec 14 00:23:43 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * tests/ASX/Event_Server/Event_Server: Fixed an "off by 1" bug in - the declaration of char *argv[3] in the open() methods of - Supplier_Router.C and Consumer_Router.C. Thanks to the "ever - dissatisfied" Alex V Maclinvosky <alexm@teltrunk1.tait.co.nz> - for reporting this. - - * libsrc/Service_Configurator/Service_Config: Added a new - "Singleton" access point for the global ACE_Allocator. - - * libsrc/Naming/Name_Options.C (parse_args): Made it possible to - change the name of the process on the command line via the -P - option. The default is still to use argv[0] as the process - name. - - * include/ace/testconfig.h (ACE_DEFAULT_GLOBALNAME): Changed the - value from "/localnames" to "/globalnames" to avoid a conflict. - - * libsrc/Misc/SString.C: Added Irfan's new "persistent" string - mechanisms that use the ACE_Allocator_Manager. We may - eventually update the existing SS* stuff to use this. - - * Merged in Jesper S. M|ller <stophph@diku.dk> updates for Windows - NT. - - * include/ace/Malloc.h: Added a forward declaration for - ACE_Malloc_Iterator right before ACE_Malloc. Thanks to Antonio - Tortorici <antonio@rh0011.roma.tlsoft.it> for reporting it. - - * libsrc/Threads/Synch_T.h: Fixed a small typo in - ACE_Null_Condition. Thanks to Antonio Tortorici - <antonio@rh0011.roma.tlsoft.it> for reporting it. - - * include: Added new config-linux.h and platform_macros.GNU config - files for Linux. Thanks to Timothy Newell - <910430n@dragon.acadiau.ca> for this stuff. - -Wed Dec 13 23:08:11 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/Addr/INET_Addr.C (set): Fixed a small typo in the - ACE_INET_Addr::set (const char port_name[], ACE_UINT32 - inet_address) method where the test should be != rather than == - 0. Thanks to Bill Lear (rael@anarchy.cybercom.net) for - reporting this. - -Sun Dec 10 12:23:54 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Service_Configurator/Service_Record.C (init): Fixed a - small problem where a NULL pointer was being returned if a user - passes a non-existent config file (using the -f option) to - ACE_Service_Config::open(). Thanks to Dieter Quehl - (quehl@erlh.siemens.de) for noticing this. - - * libsrc/Log_Msg/Log_Msg.C (log): added a new option (%T) that - causes the current timestamp to be inserted into the log msg. - Thanks to Dieter Quehl (quehl@erlh.siemens.de) for suggesting - this. - - * libsrc/Misc/Misc: Added a new timestamp() method that returns - the current timestamp in the form - "hour:minute:second:microsecond." The month, day, and year are - also stored in the beginning of the date_and_time array. - - * tests/Shared_Malloc: Added Irfan Pyarali <ip1@cec.wustl.edu> new - test program that exercises the new features of ACE_Malloc that - are described in the following bullet. - - * libsrc/Shared_Malloc: Added Irfan Pyarali <ip1@cec.wustl.edu> - cool new versions of ACE_Malloc and ACE_MMAP_Memory_Pool. These - new versions provide the following enhancements: - - 1. Persistence -- via the sync() method - 2. Protection -- via the prot() method - 3. Named malloc chunks -- via bind(), find(), unbind(). - 4. Named iteration -- via ACE_Malloc_Iterator - -Thu Dec 7 00:31:26 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Signal.C: Replaced ACE_Guard with ACE_TSS_Guard - to ensure that locks are correctly released even if - Event_Handler::handle_signal() callbacks invoke - ACE_Thread::exit(). Thanks to Detlef Becker - (beckerd@erlh.siemens.de) for suggesting this. - - * libsrc/Threads/Synch_T: Used inheritance to factor out the - shared code between ACE_Guard, ACE_Read_Guard, and - ACE_Write_Guard in order to reduce unnecessary duplication. - - * libsrc/Threads/Synch_T: Changed the implementation of ACE_Guard - to keep a pointer to the LOCK rather than a reference. This - makes the code more flexible and aids in factorization. - - * libsrc/Threads/Synch_T: Changed the implementation of ACE_Guard - to incorporate ACE_Try_Guard semantics. This reduces the amount - of classes and duplicate code in ACE. - -Wed Dec 6 21:36:02 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * include/ace/Trace: Changed the type of the string passed into - ACE_Trace from char * to const char *. - - * libsrc/Reactor/Reactor.C: Had forgotten to initialize the - initialized_ and requeue_position_ members appropriately in the - constructor of the ACE_Reactor if ACE_MT_SAFE is *disabled*. - Thanks to Mark Zusman <marklz@topaz.technion.ac.il> for pointing - this out. - - * libsrc/Threads/Synch_T.C: changed the order of some methods so - they would be properly defined if ACE_HAS_THREADS and - ACE_HAS_THREAD_SPECIFIC are *not* enabled. This should fix - remaining problems with ACE on SunOS 4 and SGI. Thanks to - Aniruddha Gokhale <gokhale@cs.wustl.edu> for noticing this. - -Tue Dec 5 01:06:14 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Changed things around so that the Name_Server and Token_Server - client interfaces are include in libACE. - - * libsrc/Shared_Malloc: added a const char *pool_name to - ACE_Malloc::ACE_Malloc. This is passed into the constructor of - the MEMORY_POOL to make it easier to dynamically name memory - pools. - -Mon Dec 4 21:20:28 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Synch_T: Modified the place that the - ACE_Thread_Specific methods are defined so that they will be - compiled correctly for platforms without threads or - thread-specific storage. - -Sun Dec 3 23:04:41 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/ASX/Message_Block: Modified clone() so that it takes an - extra parameter that specifies which flags SHOULD NOT BE - TRANSFERED to the clone. This defaults to - ACE_Message_Block::DONT_DELETE. Thanks to Alex V Maclinvosky - <alexm@teltrunk1.tait.co.nz> for suggesting this. - -Sun Dec 3 17:43:11 1995 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * The number of files in the Token library has been reduced. As a - result, many of the files have been renamed. Also, the .i files - have been purged of relatively large methods (these have been - moved to the .C files.) Lastly, most uses of dynamic memory - allocation have been removed from the library. This was - important to reduce the amount of serialization in threaded - applications caused by the dynamic allocation. - -Sun Dec 3 17:29:54 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Synch: Modified all the synchronization classes - so that they disallow assignment and initialization! - - * libsrc/Threads/Synch: Moved the ACE_Thread_Specific class from - its own files into the Threads/Synch.[Chi] files. This should - eliminate a set of horrible interdependencies among files. - -Sat Dec 2 16:07:40 1995 Douglas C. Schmidt (schmidt@mambo.cs.wustl.edu) - - * libsrc/Misc/SString.C (ACE_CString): Added a destructor to - CString. Thanks to Tim for noticing this... - -Tue Nov 28 17:25:02 1995 Prashant Jain (pjain@tango.cs.wustl.edu) - - * apps/Name_Server/client/lib/Name_Proxy: Changed Name_Proxy to - inherit from ACE_Service_Object rather than ACE_Event_Handler. - This will allow a Name_Proxy to be dynamically linked into an - application via the svc.conf file. - - * apps/Name_Server/client/lib/Name_Proxy: Added new methods - init, fini, and info. - -Tue Nov 28 00:56:52 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * tests/Threads/test_thread_specific.C: Added code to test the new - ACE_TSS_Guard class... - - * libsrc/Threads/Synch_T: Added the new ACE_TSS_Guard class. This - class is similar to the existing ACE_Guard, except that it uses - thread-specific storage to ensure locks are released even if a - thread exits via thr_exit()! - -Mon Nov 27 20:39:58 1995 Prashant Jain (pjain@tango.cs.wustl.edu) - - * apps/Name_Server/{client,server}/tests: Added new tests to - exercise the key features of the name server. - - * apps/Name_Server/client/lib: Simplified access to the nameserver - database. For example, all the network-byte ordering code was - moved out of the Local and Remote Name_Spaces. This code is no - longer necessary since we'll be providing a different means to - get portable name service repositories via a tool that extracts - the "key/value/type" tuples and stores them in a - machine-independent format. The result of this change is that - the Name_Server code is much easier to understand and modify. - - * apps/Name_Server/client/lib: Split local and remote name spaces - into two classes to simplify usage. This approach uses the - Bridge pattern to have a baseclass called Binding and then have - subclasses called Local_Name_Space and Remote_Name_Space. The - constructor of Naming_Context then allocates the right one - (i.e., it serves as a factory). This approach remove all the - switch statements in the code and makes it much easier to use - and extend. - - * apps/Name_Server: updated all the Name_Server components to - use ACE naming conventions. - - * apps/Name_Server/client/lib: Changed ACE_Name_Options to use the - Singleton pattern rather than the global variable... - -Mon Nov 27 00:47:32 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Shared_Malloc/Malloc.h: Named the previously anonymous - struct inside of ACE_Malloc_Header to be - ACE_Malloc_Control_Block in order to keep the OSE tools working. - Thanks to Karlheinz for reporting this. - - * libsrc/Threads/Synch: Fixed a major bug in the ACE_Semaphore - wrappers. Apparently, these had slipped between the cracks and - were not correctly mapping onto the ACE return value scheme - where -1 corresponds to an error with errno set to indicate the - type of error. - - * tests: Cleaned up some files that mistakenly were defining - LSOCK* objects even for platforms (i.e., Linux) that don't - support them. Thanks to Timothy Newell - <910430n@dragon.acadiau.ca> for noticing this. - -Sun Nov 26 12:42:51 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Shared_Malloc/Malloc: Added a new accessor method - (memory_pool) that returns a reference to the MEMORY_POOL object - used to configure ACE_Malloc. - - * libsrc/Shared_Malloc/Malloc: Changed the constructor of - ACE_Malloc to take advantage of the new init_release method on - all the ACE_*_Memory_Pools. - - * libsrc/Shared_Malloc/Memory_Pool: Added a new method to all the - ACE_*_Memory_Pool classes called "init_release". This is called - when ACE_Malloc finishes initializing the dynamic memory - manager. This method is necessary in order to initialize the - ACE_MMAP_Memory_Pool correctly if there are multiple processes - that try to initialize ACE_Malloc simultaneously. In addition, - also added an ACE_SV_Semaphore_Complex to the - ACE_MMAP_Memory_Pool in order to serialize initialization - correctly. - - * libsrc/Shared_Malloc/Memory_Pool: Added sync() and protect() - methods to all of the ACE_*_Memory_Pool classes in order to - support a uniform interface for use with the "robust memory" - mechanism we're building. - - * libsrc/Mem_Map/Mem_Map: Added two new "protect" methods to - ACE_Map_Manager in order to allow clients to change the - protection of memory-mapped regions. - - * libsrc/ASX/Map_Manager: Changed Map_Manager methods to use - "const" for EXT_ID and INT_ID at request of Prashant Jain - (pjain@cs.wustl.edu). - - * libsrc/Shared_Malloc/Memory_Pool: Revised the - ACE_Shared_Memory_Pool so that it would actually work - correctly... This code hadn't been reviewed carefully before - and there were some bugs... - - * libsrc/Shared_Malloc/Malloc: added "INLINE" to the - ACE_Allocator_Adapter components. - - * libsrc/Shared_Malloc/Memory_Pool: Greatly simplified and - consolidated the mmap(2) code for ACE_MMAP_Memory_Pool. - - * libsrc/Shared_Malloc/Memory_Pool.i (release): Removed the - vestigal this->mmap_.remove() call in release(), but added the - appropriate code to close the fd and unmap the region. Thanks - to Irfan Pyarali <ip1@cec.wustl.edu> for noticing this. - -Sat Nov 25 18:12:55 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/CORBA/CORBA_Handler.C (activate_service): - Modified activate_service so that - - if (service_name != 0 - && this->register_service (service_name, marker_name, - service_location) == -1) - return -1; - - is changed to - - if (service_name != 0 && service_location != 0 - && this->register_service (service_name, marker_name, - service_location) == -1) - return -1; - - Irfan Pyarali <ip1@cec.wustl.edu> requested this. - -Sat Nov 25 16:41:15 1995 Douglas C. Schmidt (schmidt@lambada.cs.wustl.edu) - - * libsrc/Misc/Set: Changed all the find() and size() methods to - be const member functions. Thanks to Irfan Pyarali - (ip1@cec.wustl.edu) for requesting this. - -Fri Nov 24 02:51:59 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Reactor.C: Fixed the Reactor so that if we're - compiling with DEADLOCK_DETECTION enabled it will create a - uniquely named mutex by stringifying "this". - -Thu Nov 23 21:45:43 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP: Changed - - * libsrc/Service_Configurator/Service_Config: Added three new - methods to allow programmers to set the process-wide Singletons - for Reactor, Service_Repository, and Thread_Manager. - -Tue Nov 21 01:59:06 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Mem_Map/Mem_Map.C: Fixed a stupid typo in map_it() that - was causing problems due to unsigned arithmetic semantics... - This should make the file_reverse.C Mem_Map tests work correctly - now... Thanks to Bill Lear <rael@anarchy.cybercom.net> for - noticing the problem. - - * tests/Mem_Map/IO-tests/io_test.C (parse_args): Fixed a - classic C/C++ braino in io_test.C: - - The for loop in parse_args() - - for (int c; (c = get_opt () != -1); ) - - should be - - for (int c; ((c = get_opt ()) != -1); ) - - How embarrassing. Maybe Bertrand Meyer is right -- C++ is too - dangerous for its own good... ;-). Thanks to Bill Lear - <rael@anarchy.cybercom.net> for finding this! - - * Removed all traces of ACE_Condition<ACE_Mutex> from the library. - This should make life much easier for compilers (like G++) that - can't grok templates very well... - - * libsrc/Threads/Thread_Specific.C (ts_object): Added a new method - that allows you to simultaneously "test and set" thread-specific - data! This is used to support a neat new trick that ensures - locks are released even if a thr_exit() is called! - - * libsrc/Service_Configurator/Service_Repository: Removed the - Recursive_Mutex from Service_Repository and replaced it with a - regular (non-recursive) mutex. Had to rewrite the code a bit so - that it wouldn't try to call internal methods that acquired the - mutex (this leads to instant deadlock!) - -Mon Nov 20 01:05:47 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Synch: Finally gave in and accepted the fact that - GNU G++ is a horrible, horrible blight on mankind... Changed - the internals of Synch.[Chi] to completely remove any - dependencies on templates. I hope this fixes some portability - problems deep in the libraries... Added several new classes to - reflect this change: ACE_Mutex_Guard, ACE_Mutex_Condition, and - ACE_Recursive_Mutex. - - * libsrc/IPC_SAP/UPIPE_SAP/UPIPE_Acceptor.C (ACE_UPIPE_Acceptor): - Fixed a stupid typo that was causing the constructor of - UPIPE_Acceptor to become inlined!!! - - * apps/Gateway/Gateway: Fixed up the Makefile so that the gatewayd - executable would compile with G++. - - * include/ace/config-irix5.3-sgic++.h: Changed the SGI config.h - file so that it uses select() rather than poll() by default. - The select() version of the Reactor is implemented more - efficiently in ACE... - - * include: Added config files for AIX courtesy of Byron Walton - <bwalton@hughes.scg.hac.com>. - - * libsrc/Reactor/Signal.C: #ifdef'd out some code in Signal.[hC] - that was causing problems for the HPUX C++ compiler. What a - *horrible* compiler! - - * libsrc/Reactor/Event_Handler.h: Added two new methods to - ACE_Event_Handler: get_priority() and set_priority(). These - will be used to control the behavior of the ACE_Reactor's - dispatching. This also required added a new data member to - ACE_Event_Handler that stores the priority (which defaults to - MIN_PRIORITY). - - * libsrc/Misc/Stack.C (enqueue): Added a new class called - ACE_Unbounded_Queue. This is required for Tim's Token_Server - connection repository stuff... - - * libsrc/CORBA/CORBA_Handler.C: Added new support to both the - single-threaded and multi-threaded versions of CORBA_Handler so - that it will now suspend/resume the services associated with a - CORBA_Handler. - - * libsrc/CORBA/CORBA_Handler.C (ACE_MT_CORBA_Handler): Updated the - constructor to use the associated Thread_Manager to spawn a new - thread. This will allow the suspend() and resume() methods to - atomically resume and suspend the daemon thread and its event - handler. - - * libsrc/Threads/Synch.h: Fixed up the order of #includes to solve - problems with circular header dependencies! - - * Had to add zillions of little changes to avoid problems with - circular includes for G++... - - * tests/ASX/Event_Server/Event_Server/Peer_Router.C (bind_peer): - Fixed a typo that had been dormant for ages due to C++'s very - late binding of templates... G++ picked this right up! - -Sun Nov 19 11:55:02 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Signal: Replaced the static HANDLER_SET stuff - withing ACE_Sig_Handlers with a different implementation using - ACE_Fixed_Set. This should fix nasty problems with static - variables on HP/UX... - - * Fixed the entire library so that all occurrences of ace_log_msg - are changed to use the ACE_LOG_MSG macro. This macro has magic - properties that should greatly simplify the effort required to - compile ACE robustly on platforms with lame C++ compilers... - - * libsrc/Log_Msg/Log_Msg: Finally got my act together with respect - to thread-specific data and the ACE_Log_Msg class. The new - version can be conditionally compiled such that it won't use the - ACE_Thread_Specific smart-pointer wrapper mechanism unless the - platform supports thread-specific storage and threads. This - will make life much easier for lame C++ compilers that can't - handle static data member templates correctly... - - * apps/Name_Server/{client,server}/lib/Makefile (LIBS): Added a - reference to -lACE in the Makefiles of the ./lib directories in - order to get GCC to work correctly... - - * Added a bunch of fixes courtesy of Bill Lear - <rael@anarchy.cybercom.net> to make ACE compile more cleanly - with GNU GCC 2.7.x. - -Sat Nov 18 11:27:40 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Misc/Trace.C: Fixed up the ACE_Trace class so that it - will compile better on platforms that don't support - thread-specific storage. The trick was to make a new Singleton - called ACE_Nest_Depth and then conditionally compile it - according to whether the platform supports thread-specific data - or not! - - * include/makeinclude/platform_sunos5_g++.GNU: Added the new - config file that should allow ACE to build correctly with GCC - 2.7.x. Todd L. Montgomery <tmont@cerc.wvu.edu> deserves a big - round of applause for getting this stuff to work! If I had a - budget, I'd give him a raise ;-) - - * libsrc/Misc/Set.C (remove): Tightened up the semantics of all - the *Set::remove() methods so that they return 1 if they - succeed, 0 if the item isn't in the set, and -1 if they fail. - Thanks to Tim Harrison for noticing the inconsistencies. - -Fri Nov 17 01:34:51 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/Logger/Reactor_Logger: Fixed up this example app so that it - would compile with GNU G++ correctly. There was a problem with - the order of include files! Thanks to Todd L. Montgomery - <tmont@cerc.wvu.edu> for reporting this. - - * libsrc/ASX/Module.C (writer): Fixed ACE_READER so that it is - properly qualified with ACE_Task_Flags::ACE_READER. Thanks to - Neil Cohen (nbc@metsci.com) for finding this! - - * apps/Gateway/Gateway/Routing_Entry: Replaced ACE_Fixed_Set with - ACE_Unbounded_Set to get around the seemingly endless problems - with HP/UX... - - * libsrc/Misc/Set: Fixed a braino in ACE_Unbounded_Set, where I'd - forgotten to define cur_size_. Thanks to Todd L. Montgomery - <tmont@cerc.wvu.edu> for reporting this. - - * libsrc/Connection/Acceptor.C: Change the #undefs of the - shorthand names PA_AC_1, PA_AC_2, and PA_AD in - libsrc/Connection/Acceptor.C to PR_AC_1, PR_AC_2, and PR_AD - (same as in Connector.C and Strategies.C). Thanks to - Dieter Quehl <quehl@erlh.siemens.de> for reporting this. - -Thu Nov 16 02:14:22 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Misc/Trace: Fixed the ACE_Trace stuff by making the - "nesting_indent_" a static data member. This will undoubtedly - break some lame C++ compilers, but it's easy enough to remove - this stuff via conditional compilation using the ACE_NTRACE - #define in ./include/ace/config.h. - - * libsrc/Threads/Thread_Specific.C (cleanup): Under no - circumstances should ACE_Thread_Specific be allowed to - called ACE_Trace. Otherwise, chaos will result! - - * apps/Name_Server/{client,server}/tests/Makefile: Switched the - order of the -lACE and -lName* so that -lACE came *afterwards* - in order for the SGI linker to pick up the symbols correctly. - - * libsrc/Reactor/Signal: I'd accidentally put the "dump" methods - in the *.i file rather than the *.C file. This was causing - problems for G++. - - * libsrc/ASX/Task: Changed all "Q_" prefixes to "ACE_" prefixes in - order to work around a bug with HP/UX... - - * Recompiled everything on SunOS 4.x with SunC++ 4.0.1. It seems - to work! - -Thu Nov 16 18:05:03 1995 Tim H. Harrison (harrison@tango.cs.wustl.edu) - - * I moved around some class declarations so that g++ can properly - instantiate templates for ACE_Token_Collection and - ACE_Token_Manager. - -Wed Nov 15 00:26:40 1995 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * The token library should now compile on platforms which do not - support threads. All token components will be compiled into the - library, but use null mutexes and condition variables. The - remote mutex library shall run properly on single-threaded - platforms, so it compiles as usual. - -Wed Nov 15 01:05:38 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Fixed a bunch of minor problems with the SGI port. Things - should work now on IRIX 5.3! - - * man/man3: Completely regenerated all the manual pages to - reflect all the recent updates. - - * libsrc: Added ACE_TRACE macros to every single method in ACE! - This will help with debugging... - -Wed Nov 15 00:26:40 1995 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * The token library should now compile on platforms which do not - support threads. All token components will be compiled into the - library, but use null mutexes and condition variables. The - remote mutex library shall run properly on single-threaded - platforms, so it compiles as usual. - -Tue Nov 14 01:58:47 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * tests/CORBA: Added a new test to illustrate the - ACE_MT_CORBA_Handler. - - * libsrc/ASX/Task.C (ACE_Task_Exit): Fixed a niggling problem with - ACE_Task_Exit. Originally, if a thread exited via an implicit - ACE_Thread::exit() (i.e., "falling off the end of the - ACE_Task::svc_run function) then the ACE_Thread_Control on the - thread stack would automatically unregister the thread from the - ACE_Thread_Manager. However, this did *not* occur if a thread - explicitly called ACE_Thread::exit() since in that case the - destructor for ACE_Thread_Control never got called. The - solution to this is a trivial change to ACE_Task_Exit, which now - maintains an instance of ACE_Thread_Control internally, which - will automatically be released when the thread-specific - thread-exit-hook destructor gets called to cleanup upon thread - exit. Since this happens regardless of whether the thread - terminates implicitly or explicitly the ACE_Thread_Manager will - always be able to clean up it's internal resources (unless the - process exit()s, which is a whole different issue... ;-)). - - * Changed all occurrences of ACE_CORBA_Handler to - ACE_ST_CORBA_Handler. Now we've got two types of - CORBA_Handlers: single-threaded (ST) and multi-threaded (MT). - Take a look at ./apps/Orbix-examples/Event_Comm/{Supplier,Consumer} - for an example of how to leverage this in a portable manner! - - * libsrc/CORBA/CORBA_Handler: Totally redesigned the ACE - CORBA_Handler stuff so that it now uses the Singleton pattern - explicitly, rather than using the half-baked static method - version... Changed the test code to reflect this update! - - * libsrc/CORBA/CORBA_Handler.C (activate_service): Changed the - check so that if <service_name> == 0 then we don't try to do a - putit (previously, this check used <marker_name>, which is less - useful...). - - * libsrc/CORBA/CORBA_Handler.C (activate_service): Removed the - <default_iterations> flag from the constructor so that we can - make the CORBA_Handler and the MT_CORBA_Handler equivalent. - - * include/ace/sysincludes.h: Added a new macro called - ACE_THREAD_EXIT_HOOK that enables application threads - (including the main thread) to register a Task * who's - close method will automatically be called when the thread - exits, either implicitly (by falling off the end) or explicitly - (by a thread calling ACE_Thread::exit ()). - - * libsrc/ASX/Task: Moved ACE_Task_Exit into the interface part of - ACE_Task so that Irfan can maybe use this in his stuff ;-). - - * libsrc/Misc: Incorporated the ACE_Date_Time class into the - release. This is an *interface* for a system independent - representation of date and time. Implementation will follow... - - * libsrc/CORBA: Added a new MT_CORBA_Handler, which makes it - very straightforward to integrate the ACE_Reactor with - multi-threaded (MT) Orbix. - - * libsrc/Threads/Token.C: Yow, fixed a dumb problem in Tokens.C - where I was failing to include the *.i file if we weren't - compiling with inlining on!!!! - -Mon Nov 13 01:13:37 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/ASX/Message_Block: Added several new methods to - Message_Block to allow users to access and set various flags. - Thanks to Alex V Maclinvosky <alexm@teltrunk1.tait.co.nz> for - suggesting this and providing a prototype implementation. - - * include/ace/sysincludes.h: Added a new macro called ACE_NDEBUG - that can be used to toggle support for "live object dumping". - If this macro is enabled then - - * libsrc/Misc/Dump.h: Added support for "live object dumping" into - ACE. This technique is implemented with the "External - Polymorphism" pattern described in a paper available at - http://www.cs.wustl.edu/~schmidt/EuroPLoP-96.ps.Z. - - * libsrc/Threads: Added new classes called *_Process_* and - *_Thread_* for ACE_RW_Mutex, ACE_Barrier, ACE_Condition, and - ACE_Semphaore. This will allow programmers explicitly state the - scope of their locks more explicitly and will also facilitate - portability to Windows NT... - - * libsrc/Threads: Updated the constructors of all the Synch and - Synch_T classes to take an option const char * called "name." - At the moment, this doesn't do anything, but when we port to - Window NT it will be used to ensure that we can name our - process-global synchronization objects. - - * libsrc/Threads/Synch: Added a new tryacquire method to - ACE_RW_Mutex to be consistent with acquire and release... - - * libsrc/Threads/Synch.C (ACE_Mutex): Added a new "name" parameter - to an ACE_Mutex in order to support process-semantics on NT... - - * include/ace/sysincludes.h: Added a #define for EDEADLK in case - some systems don't support it (this is needed by the new - ACE_*_Token stuff). - -Sun Nov 12 14:17:01 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/Name_Server: Modified the client and server test programs - so that they can both be linked statically and/or dynamically. - If svc.conf is present then dynamic linking is used, otherwise - static linking is used. This makes it much easier to test!!! - - * apps/Name_Server/client/lib/Naming_Context.C (local): Changed - things a bit so that if our server host name is "localhost" then - we assume we are local no matter what... - - * apps/Name_Server: Moved directories around a bit so that all the - tests and libs for the client/server portions of the - ACE_Name_Server build correctly... - - * apps/Name_Server/server: Replaced the ad hoc Name_Acceptor and - Name_Handler to use the official ACE_Acceptor and - ACE_Svc_Handler... This cleans up the code considerably... - - * libsrc/Threads/Synch: Added a new wrapper for the the UNIX file - locking mechanism called ACE_File_Lock. This has the same - interface as the other locking mechanisms (e.g., ACE_Mutex and - ACE_Semaphore). Therefore, it can be used in the ACE_Guard - class! - -Sat Nov 11 13:53:48 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Shared_Malloc/Memory_Pool: Improved MMAP_Memory_Pool so - that it will be smarter about remapping the file if we aren't - trying to force a fixed addr to be used for the mapping. In - particular, if we *aren't* forcing a particular address, the new - solution will be more flexible and allow the OS to determine - where to remap the memory should we need to grow the backing - store and the mapping range... - - * libsrc/Misc/Set: Implemented a simple version of the - Unbounded_Set class and its iterator. - - * libsrc/Misc/SString: Changed all the implementations of methods - in SString classes to use new/delete rather than - strdup()/free(). - - * apps/Name_Server/client/Name_Proxy: Changed rcv_reply() to - recv_reply(). - - * apps/Name_Server/client/Name_Proxy: Modified ACE_Name_Proxy so - that the constructor and open take an ACE_Synch_Options. - - * apps/Name_Server/client/Name_Options.C (ACE_Name_Options): Added - a default for the Name_Space directory called - (ACE_DEFAULT_NAMESPACE_DIR) to the testconfig.h file... - -Sat Nov 11 00:24:37 1995 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * tests/Tokens/test_token_manager/test_token_manager.C: The token - manager has a working deadlock detection algorithm. - ACE_Local_Mutex uses this to report deadlock situations. - Changes were made to ACE_Local_Mutex to fix a couple bugs which - were causing deadlock. Also, a new test application has been - added to test deadlock detection using the local mutex. - -Fri Nov 10 17:16:06 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Mem_Map/Mem_Map.h: Changed the type of <length_> from - long to size_t. - - * tests/Threads/test_thread_manager.C (main): Added a main() for - the case when there's - - * tests/ASX/UPIPE_Event_Server/event_server.C (main): Fixed a - typo that was causing problems on SunOS 4.x. - - * tests/Service_Configurator/IPC-tests/client/local_spipe_client_test.C: - added #include "ace/Log_Msg.h" (why was this working?!). - - * include/makeinclude/rules.lib.GNU: Changed the order of operations - in rules.lib.GNU from - - $(AR) $(ARFLAGS) $@ $? - -$(RANLIB) $@ - -chmod a+r $@ - - to - - $(AR) $(ARFLAGS) $@ $? - -chmod a+r $@ - -$(RANLIB) $@ - - to keep ranlib happy on SunOS 4.x. - - * apps/Time_Server: Added a Makefile - - * include/ace/sysincludes.h: Removed the <termios.h> include - since it was causing major problems on SunOS 4.x... - - * apps/Name_Server/Naming_Context.C: Fixed up a couple of problems - with casts. Thanks to Jack Erickson <jack@cibc.com> for - pointing this out. - -Thu Nov 9 15:49:40 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Synch_T: moved Atomic_Op from ./Misc to ./Threads - and merged it into the Synch_T files. This makes more sense as - a place to put it... - - * libsrc/Misc/SString.C (operator +=): Fixed a typo that would - have caused mistakes when memcpy() was used. Thanks to Prashant - Jain <pjain@wuerl.wustl.edu> for noticing this. - -Wed Nov 8 22:36:51 1995 Tim H. Harrison (harrison@lambada.cs.wustl.edu) - - * libsrc/Reactor/Reactor.C (TOKEN_GUARD): The reactor now uses the - TOKEN_GUARD macro. The Reactor can now be conditionally - compiled with ACE_REACTOR_HAS_DEADLOCK_DETECTION to use the new - ACE_Local_Mutex in conjunction with the ACE_Token_Manager to - detect deadlock. The deadlock detection algorithm has not yet - been implemented, but the hooks are now in place. - - * libsrc/Tokens: This subdir includes ACE's new Token library. - Check out libsrc/Tokens/README for more info. - - * tests/Tokens: There are a couple test applications for the new - Token library. See tests/Tokens/README for more info. - - * apps/Token_Server: This directory contains some new client - interfaces to the old ACE TokenServer, now Token_Server. There - are also some example use cases included in this directory. As - always, see apps/Token_Server/README for more info. - -Wed Nov 8 00:14:55 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/IO_SAP: Added the new classes for IO_SAP from - Gerhard Lenzer (lenzer@csaserv.erlh.siemens.de). This - eliminates UNIX I/O-specific features from ACE. - - * libsrc/Misc/Set: Added a new find() method to each of the - ACE_*_Set classes... - - * include/ace/sysincludes.h (ACE_ALLOC_HOOK_DECLARE): Changed - enum __Ace { __ACE } to struct __ACE {}. I think this - will cause less problems with M.I... - - * libsrc/ASX/Message_Block: Added a new "allocator" parameter to a - Message_Block. This allows the memory stored by a Message_Block - to come from someplace besides the normal heap (e.g., a shared - memory segment!). - - * libsrc/ASX/Message_Block.C (ACE_Message_Block): Yow, fixed a bug - in the destructor where ACE_BIT_ENABLED was being used in place - of ACE_BIT_DISABLED! I think this was causing a memory leak... - - * libsrc/Reactor/Reactor: added a pair of methods that allow a - thread to set/get the notion of who "owns" the event loop. Only - the owner of the loop can do a handle_events() call. Also - changed things so that the requeue_position() are available for - both threaded and non-threaded implementations (just to have a - uniform interface...). - - * libsrc/ASX/Message_Block: added a new constructor and a new - init() method that just assume ownership of a char * passed - as the parameter. Note that this does *not* set any other - fields in the Message_Block and is only used to ferry around - totally opaque data in the Message Block! - -Tue Nov 7 00:52:15 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * tests/Log_Msg/test_log_msg.C (main): Added some new tests to - make sure that op_status() and errnum() work on ace_log_msg. - Thanks to Tim Harrison for these tests. - -Mon Nov 6 12:55:46 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Thread_Specific: Changed a couple of places in - the Thread_Specific code so that key_ is initialized to 0 and - the ts_obj * is initialized to 0. If these *aren't* 0 then - weird bugs happen on Solaris... Thanks to Tim Harrison for - noticing this and suggesting the fix! - - * libsrc/Threads/Synch_T: Added an accessor method to obtain - the underlying mutex within ACE_Condition. - - * libsrc/Threads/Synch.C (ACE_Process_Mutex): Added a dummy - argument of type const char * to ACE_Process_Mutex. This is in - anticipation of the info required in Windows NT to support a - named process-wide Mutex. On UNIX, this argument is ignored... - -Fri Nov 3 19:02:54 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/SOCK_SAP: Back from C++ World... Fixed a couple - of typos in SOCK_Dgram_Bcast and SOCK_CODgram that included the - *.i files multiple times... Thanks to Alex V Maclinvosky - <alexm@teltrunk1.tait.co.nz> for reporting this. - -Tue Oct 31 02:12:13 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Reactor: Modifed the MT_SAFE Reactor so that the - its open() method keeps track of which thread originally created - it. This thread is then considered the "owner" of the Reactor. - If a different thread tries to run the handle_events() method - then an error is returned. - - * libsrc/ASX/Task.C: Added a "group id" field to the ACE_Task. - This can be used to suspend and resume a group of tasks - atomically. Also added default suspend() and resume() methods - that do just that! - - * libsrc/Reactor/Reactor: Made the open() method - thread-safe. Thanks to Detlef Becker (beckerd@erlh.siemens.de) - for pointing out the need for this. - -Mon Oct 30 00:02:53 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Shared_Malloc/Memory_Pool.C (ACE_MMAP_Memory_Pool): - Made it possible to configure the ACE_MMAP_Memory_Pool with a - (backing_store_) file name so that it is possible for multiple - processes to share one wellknown file, as well as to have - multiple pools per process. Check out the - ./tests/Shared_Malloc/test_malloc.C file for an example of how - this works (try the -p -e -L10000 -t3 options). - - * libsrc/Reactor/Reactor: Moved handler_i into the *.C file to - avoid problems with inline functions on HP/UX. - - * libsrc/Misc/SString: Added a new class called ACE_CString. This - class is similar to ACE_WString (which has "wide character" - size), though CString has regular "char" size. Note that both - of these classes are "true" string classes, unlike ACE_SString, - which is a very simple string class that is only to be used for - very specific purposes... - - * libsrc/Shared_Malloc/Memory_Pool.C (acquire): Fixed an - "off-by-one" error in ACE_MMAP_Memory_Pool::acquire() that was - causing an extra byte to be written to the backing store file... - This was causing the ./tests/Shared_Malloc/test_malloc.C program - to fail when -p was given. After this fix the test works - again... (thank God!). - -Sun Oct 29 22:43:25 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Shared_Malloc/Malloc: Added two new classes: - ACE_Allocator and ACE_Allocator_Adapter. ACE_Allocator uses - inheritance and dynamic binding to provide extensible mechanisms - for allocating and deallocating memory. ACE_Allocator_Adapter - implements the Adapter pattern to enable ACE_Allocator to be - used with instantiations of the ACE_Malloc<> template class. - -Sat Oct 28 13:51:07 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * tests/ASX/Event_Server: Added a new directory called - UPIPE_Event_Server, which tests a version of the Event_Server - that is instantiated with ACE_UPIPE_* IPC mechanisms, - rather than by the ACE_SOCK_* mechanisms. - - * libsrc/IPC_SAP/Addr: Created a new file called UPIPE_Addr.h. - This file contains a typedef of ACE_SPIPE_Addr to - ACE_UPIPE_Addr. The purpose of doing this is to "logically" - decouple the ACE_UPIPE* classes from the ACE_SPIPE* classes - (even though they share the same *physical* representation at - this point...). - - * libsrc/IPC_SAP: Fixed a small bug in TLI_Connector.connect() and - SOCK_Connector.connect() that failed to set the - new_stream::handle_ to ACE::INVALID_HANDLE when the connection - failed. Thanks to the ever-astute Mark Patton - (mark_patton@tx72.mot.com) for noticing this. - -Thu Oct 26 15:08:22 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * tests/Threads: created a new test program called - test_thread_manager.C that tests the new semantics for managing - groups of threads. - - * libsrc/Reactor/Signal.C (ACE_Sig_Action): Added a new method - that allows me to create a Sig_Action object that contains both - the handler and the signal to register for. This handler is - register to handle the signal in the constructor of the - object... - - * libsrc/Threads/Thread_Manager: enhanced the Thread_Manager to - add support for operations (i.e., suspend, resume, kill) on a - group of threads. - - * libsrc/Threads/Thread_Manager: Added a new method that allows - the Thread_Manager to resize itself automatically when it's - internal table gets full. - - * libsrc/Threads/Thread_Manager: Updated the return value of - Thread_Manager::spawn() and Thread_Manager::spawn_n() so that - they return -1 on failure *and the group id* on success. - Originally, they returned 0 on success, but this new return - value is more useful since it can be used to control groups of - threads atomically. - -Wed Oct 25 01:03:32 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/Name_Server: Began integrating the newly donated name - server into ACE. There are a number of dependencies on - RogueWave that must be removed, but things are looking good so - far. - - * libsrc/Misc/Set: Changed the name of ACE_Unordered_Set to - ACE_Fixed_Set to be consistent with the ACE Stack classes... - - * libsrc/Misc/Set: Added new ACE classes called ACE_Unbounded_Set, - ACE_Bounded_Set, ACE_Unbounded_Set_Iterator, and - ACE_Bounded_Set_Iterator to deal with ACE name service - stuff. - - * libsrc/Misc/SString: Added a new class called ACE_WString that - gives a very simple "wide-character" string representation for - ACE. This is needed for the ACE name service stuff. - - * libsrc/Misc/SString.C (operator =): Fixed this so that ::strdup - is matched up with ::free, rather than with delete... - - * libsrc/Log_Msg/Log_Msg.C (log): Updated the ACE_Log_Msg class to - store an ostream * in thread-specific storage. This can be used - in conjunction with the dump() method on each ACE class, as well - as with the ACE_ERROR and ACE_DEBUG logging macros. - -Tue Oct 24 00:19:13 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added a definition of the dump() method to every class in ACE in - anticipation of the changes requested for Siemens. - - * Changed all occurrences of ACE_Signal_* to ACE_Sig_* to make the - ACE naming of signal handling wrappers consistent. - - * libsrc/Threads/Thread: Fixed some obscure bugs with the way that - ACE_Thread was compiling on platforms that don't support - threads. - - * include/ace/config-irix*.h: Removed all TLI support from the SGI - platform. It seems to be totally screwed up from the tests that - I've run and there's no sense in bending over backwards to - support an IPC API that is brain-damaged to begin with... - - * apps/Logger/Service_Configurator_Logger/Thr_Server_Logger: Fixed - up the code so that the Thr_Logging_Server stuff will compile - correctly even for platforms that lack threads! - - * libsrc/Connection/Strategies: Added new strategies that provide - Singleton creation and Process concurrency policies. - - * libsrc/Connection/Connector.C (handle_close): Make sure that all - pending timer objects are removed from the Reactor's timer queue - when a Connector shuts down. In addition, make sure to remove - and delete all dynamically allocated ASTs, as well. Thanks to - Karl-Heinz Dorn (kdorn@erlh.siemens.de) for suggesting this. - - * libsrc/Threads/Thread_Manager.C (wait): Modified wait() so that - it now takes an ACE_Time_Value *, which can be used to wait - until all threads terminate or a timeout occurs... - - * libsrc/Threads/Thread_Manager: Moved Thr_Descriptor from within - the ACE_Thread_Manager class to become ACE_Thr_Descriptor at - file scope. This is in anticipation of the cool new thread - manager stuff on the way... - - * libsrc: Updated every class in ACE to include a "dump" method - with the signature "void dump (void);" This method soon will be - tied into the ACE_Dump mechanism to allow all live objects in - ACE to have their state dumped automagically on-demand. This is - useful for debugging and tracing etc. - - * libsrc: Updated every class in ACE to include a "Alloc hook." - This hook will enable all ACE classes to be allocated from a - particular memory pool. - - * include/makeinclude/rules.local.GNU: fixed the clean target to - delete the *.rpo files (else gcc -frepo can get some crazy - errors) and combines all rm-commands for the target realclean - into one command (in some cases the last two lines do not have - any files to delete, in which case rm produces an usage - message). Thanks to John Huchinson (hutchiso@epi.syr.ge.com) - for the patch. - - * libsrc/IPC_SAP/Addr/INET_Addr: Fixed all the uses of gethost* - and getserv* to use the reentrant get*_r functions if - ACE_HAS_REENTRANT_FUNCTIONS is set and ACE_MT_SAFE is set. - Thanks to Bill Tang <tang@tekats.com> for suggesting this. - - * libsrc/Misc/OS: Started adding support for the POSIX *_r - functions to the OS class. - - * include/ace: Added a new #define called - ACE_HAS_REENTRANT_FUNCTIONS. This indicates that the platform - supports reentrant functions (i.e., all the POSIX *_r functions - like gethostbyname_r). - -Mon Oct 23 21:15:50 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * include/makeinclude/platform_irix5.3.GNU (LIBS): Removed the - link of the nsl lib since it seems not to be present on this - platform. Thanks to Karel Zuiderveld - <Karel.Zuiderveld@cv.ruu.nl> for noticing this. - - * libsrc/IPC_SAP/Addr/INET_Addr.i (operator ==): Enhanced the - semantics of comparison to check both the port number and IP - address. Thanks to Mark Patton (mark_patton@tx72.mot.com) for - suggesting this. - -Thu Oct 19 00:10:28 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/Addr/INET_Addr.C (set): Fixed a stupid bug that - failed to set errno appropriately if things go wrong with this - method. Thanks to Mark Patton (mark_patton@tx72.mot.com) for - noticing this! - -Sat Oct 14 12:07:16 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Thread_Manager: Modified the Thread_Manager so - that even in the case where we are compiling for non-MT systems - the Thread_Manager still has the same method interface (all of - which are no-ops). - -Wed Oct 11 00:12:57 1995 Douglas C. Schmidt (schmidt@mambo.cs.wustl.edu) - - * Finished commenting all the classes in ACE. Updated all manual - pages accordingly. - -Fri Oct 6 14:17:17 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * tests/ASX/Event_Server/Event_Server: Changed - - ACE_SOCK_Acceptor &sa = (ACE_SOCK_Acceptor &) *this->acceptor_; - - to - - ACE_SOCK_Acceptor &sa = this->acceptor_->acceptor(); - - Thanks to Dieter Quehl (quehl@erlh.siemens.de) for suggesting - this. - -Thu Oct 5 00:22:56 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/ASX/Map_Manager: Added a new find() method to the - Map_Manager. This method only checks for the existence of an - EXTERNAL_ID, and doesn't return the INTERNAL_ID. - - * Introduced the new "trait"-based *_Connector, *_Acceptor, and - *_Stream interfaces for all the IPC_SAP classes. Basically, for - each class like - {SOCK,TLI,SPIPE,etc,}_{Acceptor,Connector,Stream}, there's now a - typedef for the appropriate type of ACE_*_Addr subclass and the - appropriate type of ACE_*_Stream class. For example, here's - what's in ACE_SOCK_Acceptor (same goes for ACE_SOCK_Connector): - - class ACE_SOCK_Acceptor - { - public: - // ... - - // = Traits. - typedef ACE_INET_Addr PEER_ADDR; - typedef ACE_SOCK_Stream PEER_STREAM; - }; - - Once C++ compilers can grok template typedefs correct, this new - approach will allow much greater simplification of code, so that - template classes like - - template <class SVC_HANDLER, class PEER_ACCEPTOR, class PEER_ADDR> - class ACE_Acceptor { /* ... */ - virtual int open (const PEER_ADDR &); - }; - - that are currently used like this: - - ACE_Acceptor <My_Svc_Handler, ACE_SOCK_Acceptor, ACE_INET_Addr> acc; - - can be replaced with - - template <class SVC_HANDLER, class PEER_ACCEPTOR> - class ACE_Acceptor { /* ... */ - virtual int open (const PEER_ACCEPTOR::PEER_ADDR &); - }; - - that are used like this: - - ACE_Acceptor <My_Svc_Handler, ACE_SOCK_Acceptor> acc; - - i.e., the ACE_SOCK_Acceptor maintains a "trait" that the - ACE_Acceptor uses to determine the appropriate addr. This is - more concise and less error-prone than the current scheme that - requires you to pass into the ACE_INET_Addr separately (ugh). - - Note that the trick to making all this work is to typedef the - PEER_ADDR trait into the ACE_SOCK_Acceptor class, as follows: - - class ACE_SOCK_Acceptor { - public: - typedef ACE_INET_Addr PEER_ADDR; // Trait... - }; - - Unfortunately, none of the C++ compilers (e.g., SunC++ 4.0.1, - G++ 2.7.0) support this stuff yet... Therefore, I've added - a set of macros that that will toggle back and forth between - whichever approach works, depending on the setting of - ACE_HAS_TEMPLATE_TYPEDEFS. Hopefully, over time compilers will - support this stuff correctly and life will become easier. - - * libsrc/ASX/Message_Queue: Changed all occurrences of the S_MUTEX - and S_CONDITION macros to ACE_SYNCH_MUTEX and - ACE_SYNCH_CONDITION in order to conform to the new ACE namespace - control conventions. - - * libsrc/Connection/Acceptor: Modified the Acceptor class to split - it into two classes: ACE_Acceptor (which implements a very - simple, very concise version of the Acceptor pattern, without - all the extra strategy mechanisms, etc.). These strategies have - now been factored out into a new class called - ACE_Strategy_Acceptor. The point of these changes is to "keep - simple things simple, but enable powerful extensions when - necessary." All the test programs that utilized the earlier - strategy version of the Acceptor have been updated to the the - Strategy_Acceptor instead. - - * libsrc/Connection/Connector: added two new protected methods, - connect_svc_handler() and activate_svc_handler(). These methods - allow subclasses to override the Connector's strategies for - connection establishment and concurrency. In addition, it makes - the pattern much easier to explain via the Connector pattern and - also is more similar to the Acceptor. - -Wed Oct 4 18:45:58 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/Orbix-Examples/Event_Comm: Fixed the examples in this - directory so that they compile with the new ACE. - -Tue Oct 3 17:33:46 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * include/makeinclude/rules.nested.GNU: Added support so that - ACE can now be built in parallel using the -jN option of GNU - make. To accomplish this, just type - - % make MAKEFLAGS=-j2 - - on the command line and the "-j2" flag will be passed through to - the make hierarchy. Once the SunC++ compiler supports parallel - makes correctly (Template.DB causes problems) this will allow me - to tke advantage of my new dual-CPU SPARCstation 20!!! - -Mon Oct 2 13:34:14 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Connection: Cleaned up some of the code related to - Time_Values * by adding a new method call time_value() to the - ACE_Synch_Options class. - - * libsrc/Service_Config/Service_Record: Changed things a bit so - that we don't have to include "ace/Stream.h" in - Service_Record.h, but instead use forward decls of the - appropriate types. This breaks a circular dependency that was - causing problems for GNU C++. Thanks to John Hutchinson - (hutchiso@epi.syr.ge.com) for finding this problem. - -Sat Sep 30 13:45:08 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Changed all uses of typedef PARENT to inherited, which is less - obtrusive. - -Fri Sep 29 01:33:54 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Misc: Completed the new OS class, which will be used - shortly to remove all direct UNIX system calls in ACE. - - * libsrc: Completed redocumented the header files for almost all - of ACE. The goal was to document all the methods in all the - classes. This has most been achieved (only a few minor changes - remain). The result is *much* better manual page entires in - ./man/man3, as well as much more consistent header files and - overall documentation for ACE. - - * libsrc/Reactor/Reactor: Changed all uses of get() to - handler_i(). Also changed the check_connections() method to - check_handles(). Note that all these changes are invisible to - apps... - -Thu Sep 28 01:22:36 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/Addr/SPIPE_Addr: Changed all occurrences of - {get,set}_user_id() and {get,set}_group_id() to user_id() and - group_id() in order to be more consistent with other parts of - ACE. - - * libsrc/ASX/Task.C (module): Modified the implementation of - several Task helper methods (e.g., sibling()) so that they don't - crash if there is not Module associated with the Task. - - * libsrc/ASX/Stream: Removed the sync_ data member from the - private part of Stream since it didn't seem to be used for - anything. - - * libsrc/ASX/Map_Manager.C (bind): Changed the type of the INT_ID - to bind() from INT_ID to const INT_ID &. - - * libsrc/IPC_SAP/Addr/Addr: Moved some methods around in the *.i - file to the *.C file in order to be smarter about inlining. - - * libsrc/Misc/Auto_Ptr.h: Added a new pair of classes called - "auto_ptr" and "auto_array_ptr". These implement the ANSI/ISO - C++ standard auto_ptr mechanism, which helps to write - exception-safe code. The code is based on material from Jack - Reeves (jack@fx.com) and Dr. Harald M. Mueller - (mueller@garwein.hai.siemens.co.at). - - * libsrc/Threads/Synch_T.h (ACE_Null_Condition): Changed the - behavior of Null_Condition::{signal,broadcast} so that they - return 0 rather than setting errno = ETIME and returning -1. - -Wed Sep 27 00:16:01 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Synch: Fixed a bug with class ACE_Barrier: count_ - wasn't being set properly. - - * tests/Threads/test_barrier.C (main): Fixed a stupid bug - in the ACE_Barrier -- the main function was exiting, thereby - destroying the barrier! - - * tests/IPC_SAP/{SOCK,TLI}_SAP: Added test cases to exercise the - new reuse_addr feature of SOCK_Connector and TLI_Connector. - - * libsrc/IPC_SAP/{SOCK,TLI}_SAP/{SOCK,TLI}_Connector: Implemented - the new behavior for reusing a local address. Also fixed a few - error cases that would have lead to descriptor leaks. - - * libsrc/IPC_SAP/SOCK_SAP/SOCK.C (open): Modified a few return - values and comparisons to ease the transition to WIN32. - - * libsrc/ASX/Task.C (ACE_Task): Changed the behavior of - Task::activate() so that it uses the - ACE_Service_Config::thr_mgr() Singleton if no thread manager has - been associated with a Task when it becomes an active object. - - * libsrc/Service_Configurator/Service_Config: Added a new static - method to class Service_Config called thr_mgr(). This static - method behaves as a "Singleton" and provides a convenient - default thread manager that is available to all threads - throughout a process. - - * libsrc/IPC_SAP: Changed all the IPC_SAP/*_SAP/*_Connector.[hiC] - files and the Connection/Connector.[Chi] class in order to add - "reuse_addr" behavior consistent with the Reactor. This enables - the client to specify that the "local_addr" should be reused - (e.g., via SOCKREUSEADDR), even if its "2 minute wait" time - hasn't elapsed yet. The libsrc/Connection/Connector.[Chi] files - were also changed to support this new interface. - - * libsrc/Log_Msg/Log_Msg.C (log): Fixed a mistake in Log_Record - caused by the new thread-safe storage enhancement. The data - being logged was being rounded up incorrectly. Thanks to Daniel - Proulx (daproulx@qc.bell.ca) for reporting this. - - * libsrc/Reactor/Signal.i (operator): Made a minor change to the - definition of operator struct sigaction * to work around a bug - with the HP/UX C++ compiler (lame, lame, lame)... - - * libsrc/Service_Config: Changed all occurrences of - ACE_Service_Config::reactor (which was originally a globally - accessible public method of class ACE_Service_Config) to - ACE_Service_Config::reactor () (i.e., made the reactor a - Singleton implemented by a static method). This was long - overdue and will fix all sorts of niggling problems with order - of initialization since the reactor() method can do "lazy - creation" of Reactors now, i.e., create one the first time it is - referenced. In addition, changed the - ACE_Service_Config::svc_rep to ACE_Service_Config::svc_rep () in - the same manner. - - * Changed all occurrences of the form: - - *_Stream stream; - *_Connector con (stream, remote_addr); - - if (stream.get_handle () == ACE::INVALID_HANDLE) - ... - - To - - *_Stream stream; - *_Connector con; - - if (con.connect (stream, remote_addr) == -1) - ... - - which is cleaner and less error prone with respect to - UPIPE_Stream (which doesn't have a valid handle once it's - connected). - - * Changed all occurrences of get_handle () == -1 to get_handle () - == ACE::INVALID_HANDLE to help smooth the move to WIN32... - - * libsrc: Created a new directory called Shared_Memory and moved - the Shared_Malloc_MM and Shared_Malloc_SV classes from the - ./Shared_Malloc directory to here, where they are now called - Shared_Memory_MM and Shared_Memory_SV. This is a better - name/place for them since they never really had anything to do - with malloc in the first place! What remains the Shared_Malloc - is the Malloc.* and Memory_Pool.* classes, which are typically - used for truly shared malloc/free. - - * apps/Gateway/Gateway: added new logic to the Gateway to enable - it to specify which local port to bind() to. - -Tue Sep 26 21:17:29 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Connection/Strategies.C (open): Added a return 0; at the - end of the ACE_Thread_Strategy::open method. - - * tests/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.C: - Made CLI_Stream a template so that we don't have to worry about - multiple includes of classes... - -Mon Sep 25 01:41:27 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP: Revised the close() method of TLI_SAP and - SOCK_SAP so that they don't try to close down a handle that == - ACE::INVALID_HANDLE. - - * Changed all uses of ::free ((char *) ...) to ::free - (ACE_MALLOC_T (...)) to work around inconsistent prototype - problems with some compilers. - - * include/ace/sysincludes.h: Changed ACE_MALLOC_TYPE to - ACE_MALLOC_T which is a bit less verbose... - - * libsrc/Service_Configurator/Makefile (BUILD): Fixed the argument - to sed from -s (which is invalid) to -e (which is valid). - Thanks to Doug Ritter (dougr@guilder.datalytics.com) for - noticing this. Also used sed to do a more elegant fix on the - age-old problem of inconsistent prototypes for free() and - realloc()... - - * libsrc/IPC_SAP/UPIPE_SAP: Rewrote all the UPIPE_* classes to - remove any dependencies on class UPIPE. This class appears to - be unnecessary since it mimics the behavior of class SPIPE. To - simplify the behavior of the UPIPE_* classes, they now inherit - from the SPIPE_* classes where appropriate. - - * libsrc/IPC_SAP/UPIPE_SAP: Changed the semantics of the - UPIPE_Connector and UPIPE_Acceptor connection methods so that - they close down the SPIPE_Stream after a connection is - established successfully. This is important to conserve - descriptors. - - * libsrc/Misc: Created a new class called OS, which encapsulates - *all* of the UNIX system calls and library routines within a - single class. The rest of ACE will program only to the methods - in this interface, which will make it much easier to port to - other versions of UNIX (and WIN32!). - -Sun Sep 24 11:49:47 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/SOCK_SAP: Conditionally compile the LSOCK_* stuff - if the OS platform (e.g., Linux) doesn't support it. - - * Changed all occurrences of ACE_HAS_NO_... to ACE_LACKS_... in - all the config*.h files and the headers/source. This reads - better... - - * Changed all uses of (1) Acceptor::peer_acceptor_ to - Acceptor::acceptor(), (2) Svc_Handler::peer_ to - Svc_Handler::peer(), and (3) Connector::peer_connector_ to - Connector::connector() to make the code more abstract and - resilient to future changes. - - * include/ace/sysincludes.h: Added a new macro called - ACE_NEW_RETURN that provides a useful abstraction for - expressions involving operator new since we can change memory - allocation error handling policies (e.g., depending on whether - ANSI/ISO exception handling semantics are being used). - - * libsrc/Threads/Thread.C: Changed things a bit so that if - ACE_MT_SAFE == 0 then Thread::self() returns 1, regardless of - whether the platform supports threads. - - * Went through the entire library and (hopefully) made sure that - all calls to global system calls and library routines are - prefixed with "::". - - * libsrc/Misc/Get_Opt.C: Changed this class to use the Log_Msg - logging mechanism rather than stderr... - - * tests/Misc: Added a new test program to test the Profile_Timer. - - * tests/Reactor/misc: Added a new test program to test the - Handle_Set. - - * libsrc/Service_Configurator: Changed the error messages in - Svc_Conf.y and Svc_Conf.l to go to the ACE Log_Msg logging - mechanism rather than stderr... - - * libsrc/Connection/Acceptor: Modified the Acceptor and - Oneshot_Acceptor classes so that they take advantage of the new - ACE_Creation_Strategy, ACE_Accept_Strategy, and - ACE_Concurrency_Strategy components. This will make is easy to - define Acceptors that can be flexibly configured to use various - creation strategies (e.g., dynamic linking, singletons, dynamic - memory creation, etc.) for making Svc_Handlers. - - * libsrc/Connection/Svc_Handler: Added several new classes -- - ACE_Creation_Strategy, ACE_Accept_Strategy, and - ACE_Concurrency_Strategy -- that form the heart of the new - ACE_Acceptor implementation. These classes define the creation, - passive connection acceptance, and concurrency strategies - employed by the Acceptor factory when it receives a connection - from a client. - - * libsrc/Connection/Acceptor: Modified the implementation of the - Acceptor and the Oneshot_Acceptor. These classes are no longer - related by inheritance since they behave in fundamentally - different ways and sharing code was making it hard to write and - use these classes correctly. - - * libsrc/Misc/Misc: Moved the enum INVALID_HANDLE from IPC_SAP.h - to Misc.h since this is actually more general than just the - sockets stuff and we need to be portable to WIN32... Therefore, - any code that originally said ACE_IPC_SAP::INVALID_HANDLE should - now be ACE::INVALID_HANDLE. - - * Removed the ACE_OMIT_SERVICE_CONFIGURATOR flags. These are - annoying -- anyone who wants to subset ACE should be responsible - for doing this stuff. - -Fri Sep 22 22:36:33 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Thread_Spawn.C: Greatly simplified the - implementation of Thread_Spawn by leveraging the new class Task - semantics for activate(). Now, all the concurrency activation - mechanisms necessary to create active objects are associated - with a Task and all the Thread_Spawn needs to do is to define a - new make_svc_handler() Factory Method to create a SVC_HANDLER - and activate it! - - * libsrc/ASX/Task.C: Tightened up the semantics of Task::activate - (which turns a passive object into an active object, i.e., one - with its own thread). Now, if an object is activated more than - once it ignores the other requests, unless the force_active - parameter is enabled. Moreover, activate() now takes a - parameter that indicates the number of threads to allocate for - the Task. This makes it simple to have a "thread pool" - associated with a Task. - -Thu Sep 21 00:49:55 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * tests/Connection: Updated the CPP-acceptor and CPP-connector to - use the underlying Acceptor and Connector patterns more - robustly. Also added new hooks to include a Service_Config - component so that integrating this with the ACE dynamic linking - scheme will be a snap! - - * libsrc/Connection/Acceptor.C: Revised the Oneshot_Acceptor to be - robust in situations where it isn't given a Reactor *... - - * apps/Logger: Fixed a couple of minor problems with *.i files - being included when __INLINE__ is set. This should help G++ - compiler ACE better... - - * libsrc/Reactor/Reactor: Enhanced the Reactor::notify() method so - that it takes both an Event_Hander * and a Reactor_Mask, which - it passes to the Reactor's main event loop thread via the pipe. - The event loop thread uses this mask to determine which method - to invoke. This new feature is due to the insight of Karl-Heinz - Dorn (kdorn@erlh.siemens.de). - - * libsrc/Connection/Connector: Fixed a braino in - Connector::handle_output, which was using ::getpeername() to - check whether a connection has been established with a peer. - Naturally, this only works for sockets, and doesn't work at all - for TLI or SPIPEs... - - * libsrc/IPC_SAP/Addr/SPIPE_Addr.C (set): Changed the return type - of this method to "int" in order to conform to the types - expected by the Acceptor/Connector patterns. - - * Removed all uses of the global scope "::" for all variables and - methods that are not UNIX system calls or library calls in - preparation to change over to the new OS class (requested by - Siemens). - -Wed Sep 20 14:39:08 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/SPIPE_SAP: Renamed the SPIPE_IO classes to - SPIPE_Stream to be consistent with the other parts of the ACE - library. Updated all parts of the library to reflect this - change. - - * tests/Service_Configurator: Moved the current contents of this - directory into a new directory called IPC-tests. Created a new - directory called Connection-tests where the dynamic linking - examples for Siemens will go. - - * libsrc/Reactor/Signal: Made a bunch of minor changes to support - signal handling on SunOS 4.x platforms. Thanks to Aniruddha - Gokhale <gokhale@cs.wustl.edu> for help with this. - - * libsrc/Threads/Synch.h: Modified the #ifdefs a bit so that - Synch_T.h gets included regardless of whether ACE_HAS_THREADS. - - * libsrc/Threads/Synch_Options: Added a new set() method to make - it possible to initialize the Synch_Options from outside the - constructor. - - * libsrc/Connection/Svc_Handler.C: Added checks within the - ACE_Svc_Handler so that if we are given a NULL Reactor we don't - crash! - - * libsrc/Mem_Map: Tidied up this class and added comments to the - header so that the class2man has something to generate manual - pages from! - - * libsrc/Misc/Misc: Added a new method called "round_to_pagesize", - which was previously in Mem_Map. This is a better place for it - since other parts of ACE (e.g., Shared_Memory) use it. - - * libsrc/Misc/Misc: Added a new method called "get_file_size", - which was previously in Mem_Map. This is a better place for it - since other parts of ACE might want to use it. - -Tue Sep 19 00:24:41 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released a beta version of ACE 3.3.1 for G++ testing. - - * libsrc/IPC_SAP/SOCK_SAP/SOCK_Dgram.C: Removed a stray INLINE - that was causing problems for G++. Thanks to E. Jason Scheck - <jasons@ims.com> for reporting this. - - * libsrc/IPC_SAP/Addr/INET_Addr: Improved the documentation for - this class and also added new semantics to the constructor and - set() method so that a "ip_addr:port_number" tuple can be given - as a single string (e.g., "1234:tango.cs.wustl.edu" or - "1234:128.252.166.57"). This is useful since it gives a uniform - interface for addressing for Internet domain, UNIX domain, and - SPIPE domain addresses... Updated the ./tests/Connection tests - to use this form (which is nice since now they are all very - orthogonal!) - - * tests/Connection: Created a whole new suite of tests that - exercise the connection patterns for all of the relevant IPC - mechanisms (e.g., SOCK_SAP, TLI_SAP, SPIPE_SAP, and UPIPE_SAP). - - * bin/clone.C: fixed the first #include so that it uses #include - "ace/sysincludes.h". Thanks to Alex V Maclinvosky - <alexm@teltrunk1.tait.co.nz> for noticing this. - -Mon Sep 18 01:52:07 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/ASX/Message_Queue.C (close): Fixed yet another problem - with variables being defined in for loops. G++ is good for - detecting this ;-). - - * libsrc/Threads: Moved all the template classes from Synch.* into - Synch_T.* in order to make it possible to compile templates with - G++. Thanks to E. Jason Scheck <jasons@ims.com> for suggesting - this. - - * libsrc/IPC_SAP/UPIPE_SAP: Make a number of changes to ensure - that all the UPIPE_SAP classes conform to the same interface as - all the other ACE IPC classes. - - * Changed all occurrences of THR_FUNC to ACE_THR_FUNC to protect - the global namespace better. - -Sun Sep 17 13:36:23 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * tests/ASX/Message_Queue: Fixed a typo in these test programs - that caused a segfault since a vararg parameter was omitted on a - call to the Log_Msg::log() method. Maybe iostreams isn't so bad - after all... ;-) - - * apps/Logger/Service_Configurator_Logger/Thr_Server_Logger: fixed - a stupid error that was caused by some mods I made after ECOOP - to update the threaded logging server. When I changed the - Thr_Logging_Acceptor so that it no longer inherited from the - Logging_Acceptor I forgot to redefine the init() method... - - * man: Totally regenerated the ACE manual pages using the new - versions of the OSE tools provided by Karl-Heinz Dorn - (kdorn@erlh.siemens.de). - - * Changed all occurrences of MT_SYNCH and NULL_SYNCH to - ACE_MT_SYNCH and ACE_NULL_SYNCH, respectively. This is - consistent with the ACE naming conventions and had been an - oversight when I renamed everything earlier. - - * Fully built and tested ACE with the __INLINE__ flag enabled. - This will generate code with many small methods in the library - inlined. Had to fix a bunch of minor things to allow this to - work without compilation-order dependency problems. - - * libsrc: Made a bunch of changes to the way that header files are - included internally to ACE in order to break compilation-order - dependencies. This is necessary to support GNU G++'s lame - handling of templates. None of this stuff should affect - application code. - - * tests: Added a whole new slew of tests for the remaining parts - of ACE that weren't currently included in ./tests. This stuff - exercises ACE components like the Log_Msg logger and factors all - the #if defined (DEBUGGING) code out of the ./libsrc directory - tree and puts it in the ./tests directory tree, where it - belongs. - - * Changed all uses of the error macros LM_* to ACE_* in order to - avoid name collisions with other libraries, frameworks, and - toolkits. In addition, changed all uses of the error enumerals - LOG_ to LM_ in order to avoid a conflict with system #defines in - <sys/syslog.h>. - - In order to change these automatically, I used the following - UNIX command sequence: - - % find . -type f -print | xargs perl -p -i -e 's/LM_/ACE_/g' - % find . -type f -print | xargs perl -p -i -e 's/LOG_/LM_/g' - -Sat Sep 16 11:55:18 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * tests/Threads: Added a new test for Thread_Specific storage. - - * Added a new platform/compiler configuration flag called - ACE_TEMPLATES_REQUIRE_SOURCE that must be set for compilers - (e.g., GNU G++) whose template mechanism must be able to - see the source code (i.e., the *.C files). Changed *lots* of - header files to enable this... Also had to change the - corresponding *.C files so that they wouldn't get included - twice... - - * libsrc/Connection: redid the implementation of Acceptor, - Connector, and Svc_Handler to get more control over the scope of - #defines like #define SH SVC_HANDLER, etc. - - * libsrc/Threads/Thread_Spawn: Totally redid the implementation of - Thread_Spawn to use the Acceptor class template. This greatly - reduces the amount of code to implement the Thread_Spawn! - - * libsrc/Threads/Thread_Spawn: Moved the Thread_Spawn - implementation into the ./libsrc/Threads directory rather than - in the ./libsrc/Service_Configurator directory since it deals - with threading and thus belongs in the other place. - -Fri Sep 15 00:25:51 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Token.i (tryacquire): Added a cast to fix passing - a const pointer to a function that was expecting a non-const. - Thanks to E. Jason Scheck <jasons@ims.com> for reporting this. - - * libsrc: Added a bunch of changes to enable G++ to compile ACE. - A lot of this involves moving around info in header files so - that templates can be dealt with using the relatively lame GNU - C++ repository scheme. Thanks to E. Jason Scheck - <jasons@ims.com> for all his help in this. - - * libsrc/Synch: created Synch_Options.C out of Svc_Handler.C, so - that Svc_Handler.C could be "template pure"; all the other files - were already separated. Thanks to E. Jason Scheck - <jasons@ims.com> for recommending this. - - * Makefile (clone): Added a tiny fix that solves a weird problem - that arises with symbolic links on HP/UX. Thanks to Jam Hamidi - (jh1@osi.com) for tips on how to fix this. - -Thu Sep 14 10:55:30 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/Gateway/Gateway/Channel.C (route_message): Updated the main - routing code to check for whether a channel is_active() - (i.e., is actually connected) before trying to send messages - to it. This was originally done in the Set class iterator, but - I revised that to make it more reuseable and to workaround bugs - in the HP/UX compiler so I had to update the main code... - - * libsrc/Threads/Thread_Specific: Added a new method to called - ts_object () to class ACE_Thread_Specific that get the - thread-specific object for the key associated with this object. - Returns 0 if the data has never been initialized, otherwise - returns a pointer to the data. This is useful since now you can - query a thread-specific storage mechanism to see if there's ever - been a thread-specific object created *without* having to - actually create one if one hasn't been created yet! Thanks to - Detlef Becker (beckerd@erlh.siemens.de) for pointing this out. - - * include/makeinclude/platform_sunos5_sunc++_orbix.GNU (LIBS): - Changed the default compilation strategy for SunOS 5.x machines - to use -mt. This seems to be necessary to build robust - libraries that are thread-safe. Thanks to Phil Mesnier - <phil@yakko.envision.com> and Chris Cleeland - <chris@envision.com> for hounding me until I changed the - existing solution. If you *don't* want this behavior you need - to remove -mt from the platform_macros.GNU file and and remove - the ACE_HAS_THREADS and ACE_MT_SAFE flags, etc. from the - config-sunos5.*.h files. - - * libsrc/Shared_Malloc/Memory_Pool.C (ACE_MMAP_Memory_Pool): Added - a new parameter to the constructor called write_each_page that - if enabled forces a write to each page to ensure that space is - allocated from the file system (otherwise, we can end up failing - due to optimisitic resource allocation...). Thanks to Phil - Brooks <phil_brooks@mentorg.com> for detecting this issue and - implementing a solution. - - * include/ace/sysincludes.h: Added #ifdef support for HP/UX, which - fails to properly wrap <sys/mman.h> with an extern "C" block. - -Mon Sep 11 01:39:35 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Connection/Connector.C (handle_input): Changed the call - to Svc_Handler::close() to accept the default value of 0 rather - than -1... Thanks to Mark Seaborn - <mseaborn@itthp1.comm.mot.com> for noticing this. - - * libsrc/Connection: Changed all uses of ADDR to PEER_ADDR to - avoid a name clash in Linux... Thanks to James Morris - <jmorris@aurora.apana.org.au> for finding this. - -Sun Sep 10 03:56:18 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Synch: Added support for "barrier - synchronization" to ACE in the form of ACE_Barrier. Thanks to - Bruce Worden (bruce@betsy.gps.caltech.edu) for suggesting this - and pointing me in the right direction. - - * tests/Threads: Added a test for the new barrier synchronization - mechanism. - -Sat Sep 9 11:58:16 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Reactor: Changed Reactor::max to Reactor::max3 to - avoid problems with conflicting names of macros in Sun header - files! - -Mon Sep 4 14:34:52 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Signal: The new ACE_Signal_Handlers mechanism - appears to be working! There's a test in ./tests/Reactor/misc - called test-signal.C that illustrates how all this works. - - * libsrc/Reactor/Signal: Added several new methods to - ACE_Sig_Action to make life easier to implement the new - ACE_Signal_Handler code... - - * libsrc/Reactor/Signal.C (ACE_Sig_Action): Changed the order of - the arguments to the ACE_Sig_Action constructor. It's almost - always the case that you want to vary the SignalHandler, but - only rarely do you want to vary the mask or flags. By - reordering this, it's easier to get the correct default values - without adding extra junk... - -Mon Sep 4 01:11:29 1995 Tim Harrison (harrison@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/SOCK_SAP/SOCK_Dgram_Multicast: added support to - allow a port to be reused for multicast sockets. This is useful - if you are multicasting to multiple processes, some of which are - on the same host! - - * libsrc/ASX/Map_Manager: Fixed an odd bug that must have gone - undetected for a long time somehow. Basically, the "is_free_" - field of the ACE_Search_Structure struct was never being set to - it's correct initial value of 1. I don't know how this didn't - surface before... At any rate, it is fixed now... - - * include/ace/sysincludes.h: Changed the inline methods for - SET'ing and CLR'ing bits to be macros in order to get cheap - polymorphic behavior... Also changed them to use the prefix - "ACE_" to avoid namespace pollution. Changed all dependencies - in the source code (only a few...). - - * libsrc/Reactor/Signal: Added a new class called - ACE_Signal_Handlers, which subclasses from ACE_Signal_Handler. - This new class implements the semantics required for Siemens. - For example, this class allows multiple signal handlers to be - registered for the same signal. It also makes SA_RESTART the - default mode. Note that by default, the Reactor uses the - original ACE_Signal_Handler semantics. If you want the new - semantics, simply pass the Reactor a pointer to - ACE_Signal_Handlers. - - * include/ace/sysincludes.h: Removed the automatic inclusion of - ./libsrc/Misc/Misc.h from sysincludes.h since this was causing - problems with include file ordering. - -Sun Sep 3 00:22:11 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Signal.C (remove_handler): Moved a definition of - ACE_Sig_Action out of an inner block to avoid portability - problems. - - * libsrc/ASX/Map_Manager: Improved the documentation of this class - and fixed up a couple of problems with the scope of loop - indexes. - - * libsrc/Misc/{Stack,Set}: Added this new file that contains a set - of Stack and Unordered Set implementations. The Unordered Set - is used in various places in ACE (e.g., libsrc/Reactor/Signal - and apps/Gateway/Gateway/Routing_Entry). - - * libsrc/Log_Msg/Log_Msg: Moved the definition and declaration of - Thread_Specific<Log_Msg> ace_log_msg from this directory to - ./libsrc/Misc/Misc.h in order to cleanup the namespace and also - to help make this work on DEC platforms... - - * libsrc/Reactor/Signal: Changed ACE_Signal_Handler from a static - class to a non-static class in order to allow subclassing. This - is necessary to support the Siemens requirements. - - * libsrc/Shared_Malloc/Memory_Pool: Modified ACE_MMAP_Memory_Pool - so that it no longer stores the name of the backing store in a - static character array (which made it impossible to have more - than one of these at a time...). The new version stores the - name in each ACE_MMAP_Memory_Pool object. It also selects a - name that won't conflict with other names by using ::mktemp. - - * tests/Shared_Malloc/test_malloc.C (parse_args): Fixed two stupid - omissions of "break" when parsing command-line arguments. Isn't - C++ great?! (NOT)... - - * apps/Synch-Benchmarks: Came up with a killer solution to the - nagging problem of POSIX Pthread's lack of an integral thread id - (a la Solaris threads thr_self()). The solution leverages off - of our new ACE_Thread_Specific wrapper to provide the necessary - functionality. Thanks to Reginald S. Perry (perry@zso.dec.com) - for triggering the thoughts that lead to this solution... - -Sat Sep 2 17:00:46 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/TLI_SAP/TLI_Acceptor: Changed the implementation - of ACE_TLI_Acceptor so that ACE_TLI_Request is defined inside - the TLI_Acceptor.C file (this is the so-called "Cheshire Cat" - technique). This clean up the code and the global namespace a - bit. - -Fri Sep 1 00:53:47 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released new version of ACE 3.3 - - * libsrc/IPC_SAP/UPIPE_SAP/UPIPE.C: Fixed a small problem with - failing to #ifdef this file correctly if we don't have - threads... Thanks to John Morey (jmorey@hitel.com) for - reporting this. - - * tests/ASX/CCM_App/svc.conf: Fixed the svc.conf file so that it - looked in the .shobj directory rather than the .obj directory. - - * Released new version of ACE 3.2.9... - - * libsrc/Log_Msg/Log_Msg: Added a new field called "restart_" to - the thread-specific storage. This will be used to control - whether system calls are restarted when interrupted. - - * Changed inheritance syntax from - - class xxx - : public yyyy - { - }; - - to - - class xxx : public yyyy - { - }; - - so that the OSE tools would work correctly. - -Thu Aug 31 00:12:40 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/UPIPE_SAP: Changed all uses of UPIPE_Addr to - SPIPE_Addr since they were the same thing. This also allows - much reuse of code... - - * libsrc/IPC_SAP/{TLI_SAP,SOCK_SAP,SPIPE_SAP}: fixed the - "complete" method for these classes so that it uses the new - ACE::handle_timed_complete() method in libsrc/Misc. This cleans - up the code by merging common logic. - - * libsrc/IPC_SAP/{DEV_SAP,FILE_SAP,SPIPE_SAP}: fixed the "connect" - method for these classes to conform to the API used by the - SOCK_SAP and TLI_SAP wrappers. In addition, cleaned up the code - so that common logic was pushed into a new method in libsrc/Misc - called ACE::handle_timed_connect(). - -Wed Aug 30 00:20:18 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Connection/Acceptor.C (open): Fixed this method so that - it returns a value on all paths through the code... - - * libsrc/IPC_SAP/TLI_SAP/TLI.C (ACE_TLI): Moved the option - allocation code from the TLI::open() method into the TLI - constructor in order to make sure it is always called! - - * libsrc/IPC_SAP/DEV_SAP/DEV_Connector: Changed the signature of - the DEV_Connector::connect method to allow users to specify - flags, permissions, and timeouts (this is now consistent with - other parts of ACE). - - * libsrc/IPC_SAP/FILE_SAP/FILE_Connector: Changed the signature of - the FILE_Connector::connect method to allow users to specify - flags, permissions, and timeouts (this is now consistent with - other parts of ACE). - - * tests/IPC_SAP/TLI_SAP: Updated the test code to check the new - timer support for connection establishment. - - * libsrc/IPC_SAP/TLI_SAP: Updated the code to make it conform to - the interfaces provided by SOCK_SAP. This primarily affected - the TLI_Acceptor and TLI_Connector classes in order to add - support for timed connects and accepts. - - * libsrc/Reactor/Signal.C: Modified Signal_Handler::dispatch so - that it saves/restores errno to prevent it from being corrupted - by the handle_signal callback. Thanks to Detlef for suggesting - this. - - * libsrc/Shared_Malloc/Memory_Pool: Changed the name of - ACE_Local_Memory_Pool to ACE_Sbrk_Memory_Pool. Then added a new - version of ACE_Local_Memory_Pool that uses the C++ operator new - to acquire chunks of memory. This enables the ACE Malloc class - to integrate with existing programs that use new/delete. Thanks - to Karlheinz for suggesting this. - - * libsrc/IPC_SAP: Added the UPIPE mechanism donated by SIEMENS. - This provides an intra-process IPC mechanism that has the same - API as the interprocess and network mechanisms. - - * Reran catman on ./man/windex. Thanks to Dieter Quehl - (quehl@csaserv.erlh.siemens.de) for reporting the need for this. - - * Released new version of ACE 3.2.9... - - * tests: Fixed a bunch of minor problems that occurred when - building on HP/UX. Thanks to John Morey - (jmorey@hitel.com) for reporting these. - - * apps/Gateway/Gateway/Peer_Message.h: Changed the default values - of the parameters to Peer_Addr so they aren't trying to assign - negative values to unsigned chars! Thanks to John Morey - (jmorey@hitel.com) for noticing this... - -Tue Aug 29 18:52:17 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Thread/Thread_Specific: Changed the constructor so - that it will take an initial TYPE *, which will be used to - initialize the thread-specific object. This is necessary to - support the changes to ACE_Task described in the following - bullet. - - * libsrc/ASX/Task: Added a new class called ACE_Task_Exit to - Task.C. This class is used in conjunction with - ACE_Thread_Specific to keep exit information for a Task in - thread-specific storage. This ensures that the Task::close() - method will get called no matter how the thread exits (e.g., via - Thread::exit() or by "falling off the end of Task::svc_run"). - -Mon Aug 28 09:54:35 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released new version of ACE 3.2.9... - - * libsrc/Reactor/Handle_Set.C: changed the type of MSB_MASK from - u_long to ACE_UINT32 to handle problems with the Alpha's 64 bit - longs... - - * libsrc/Threads/Thread_Specific: Continued to try and get this - class to build correctly on other platforms... I think I've - just about got it working right now... - - * libsrc/IPC_SAP/IO_SAP/IO_SAP: Added installation flags that - indicate whether the platform has terminal ioctl flags like - TCGETS and TCSETS. I know that SunOS 5.x has these, but I'm not - sure about other platforms... - -Sat Aug 26 13:55:45 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released new version of ACE 3.2.9... - -Fri Aug 25 09:05:09 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Thread_Specific.h: Fixed a typo that was causing - this file to fail on HP/UX. Thanks to Neil Cohen - (nbc@metsci.com) for finding this! - - * libsrc/IPC_SAP/DEV_SAP/DEV_IO: Added conditional support for - getmsg/putmsg calls in the DEV_IO class. This will make things - work correctly for platforms that don't support SVR4 STREAM - pipes. - - * libsrc/IPC_SAP/FILE_SAP/FILE_IO: Added the same fixes to FILE_IO - that I added to DEV_IO... - - * include/ace/sysincludes.h (MAXNAMELEN): Fixed a typo in - sysincludes.h that caused problems for the G++ compiler. - - * libsrc/Connection/Acceptor.C (handle_close): Removed a - diagnostic message that was getting printed if a - Oneshot_Acceptor had already been removed from the reactor (it's - ok for this call to fail). Thanks to Irfan Pyarali - (ip1@cec.wustl.edu) for noticing this! - - * libsrc/ASX/Task.C (ACE_Task): Fixed a bug in the constructor - that prevented a Message_Queue from being allocated - automagically. - -Thu Aug 24 16:47:14 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * include/ace/sysincludes.h: added support for 64 bit machines so - that Internet addresses are 32 bits, as they must be! - - * libsrc/Shared_Malloc/Malloc: Changed things so that MALLOC_STATS - is now *off* by default... (also changed the name to - ACE_MALLOC_STATS). - -Wed Aug 23 15:21:25 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * include/ace/config-osf1.h: Added support for thread-specific - storage. Please let me know if this breaks on OSF/1! - - * libsrc/Threads/Thread: Added support for the thread-specific - storage wrappers for both Pthreads and Solaris threads. Also, - rearranged some of the code to emphasize similarities between - Pthreads and Solaris threads. - - * libsrc/Threads/Thread_Specific: Updated this to remove "static" - from all the data members in this class since those should be - specific to an *instance* rather than to an instantiation of the - particular template class. Tim claims this works... - - * libsrc/Threads/Token.C: Fixed a couple of typos that misspelled - "assert" (jaysus...). Thanks to David Trumble - (trumble@cvg.enet.dec.com) for noticing this. - - * libsrc/Threads/Token.C (release): Fixed a very stupid bug that - was causing the Token never to become "unused"... No excuses - for this, except that Pthreads is partly responsible ;-) - -Tue Aug 22 11:36:58 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/ASX/Task: Changed the behavior of task so that it doesn't - try to delete the Message_Queue or Thread_Manager if it didn't - allocate them! Thanks to Karl-Heinz Dorn - (kdorn@erlh.siemens.de) for suggesting this fix. - - * libsrc/ASX/Message_Block: Changed the semantics for - Message_Block::end() so that it returns a pointer to 1 past the - end of the data. This is more consistent with toolkits like - STL. Also changed the behavior of Message_Block::copy() so that - it checks to make sure the data will fit in its buffer. - - * tests and apps: Revised a bunch of files to add #ifdef so that - TLI tests and apps are not compiled if the platform doesn't - support it... - - * Fixed a bunch of minor problems for HP/UX (which lacks TLI and - other common OS features). Thanks to Mark Seaborn - (mseaborn@itthp1.comm.mot.com) for noticing these. - -Mon Aug 21 00:19:29 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Misc: Changed the name of the class Argument_Vector to - ACE_ARGV. This is a bit more concise... UNIX programmer will - know precisely what argv is... - - * Updated all of ACE to use the new naming scheme, which prepends - all ACE classes with "ACE_". This is an important change since - it prevents ACE from polluting the namespace of applications - (unless they also prefix "ACE_" in front of their classes, which - is not very likely!). - - Since this change basically affects every single file in the - entire release, as well as all existing user code I've written a - perl script called "rename-ace.pl" to automate all of this. - This script is in $WRAPPER_ROOT/bin. To use it, simply type: - - % find . -type f -print | egrep '[Chi]$' | xargs rename-ace.pl - - Note that you will need to change the first line of - rename-ace.pl to point it to whereever perl is located on your - system. - - I've tested this on the entire ACE source code base and it seems - to work fine. Please be careful using it on your code, however, - since it may conflict with names that you use. When in doubt, - remove the '-pi' from the first line of the rename-ace.pl perl - script and replace it with '-p' (which is non-destructive). - Then run the commands above and check the output carefully. - When you're convinced that everything is ok, add the '-pi' back - again. Let me know immediately if you find any problems with - this scheme! - - * libsrc/Connection/Acceptor.C: Added a virtual destructor to the - Oneshot_Acceptor to make sure that descriptors are closed down - correctly. Thanks to Irfan (irfan@wuerl.wustl.edu) for - suggesting this. - - * libsrc: Change all occurrences of Shared_Memory to - SV_Shared_Memory to firmly indicate the origins of this - wrapper... - -Sun Aug 20 23:12:03 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP: added the IO_SAP, DEV_SAP, and FILE_SAP - components donated by SIEMENS to the ACE release. - - * libsrc/ASX: Split the Message_Queue.* files into Message_Block.* - and Message_Queue.* in anticipation of the Windows NT port... - -Fri Aug 18 13:54:09 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Thread_Specific: Move the operator->() - method back into the *.C file in order to make HP/UX - happy... - - * apps/Gateway/Peer: Removed the Options.* files since they - weren't being used and they were causing problems on OSF/1... - - * libsrc/Misc/Profile_Timer: Factored common code together by - making a new typedef called Rusage that defaults to either - struct rusage or prusage_t, depending on installation flags. - Fixed a couple places in the code that were depending on the - prusage_t type (which is now the Profile_Timer::Rusage type...). - -Thu Aug 17 14:31:11 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Connection/Connector.h: Changed some typedefs in order to - keep the Centerline compiler from crapping out. I can't - *believe* how screwed up that compiler is when it comes to - templates... - - * Released new version of ACE 3.2.9... - - * libsrc/Threads/Synch: Fixed a bunch of typos that showed up - on OSF/1. Also tried to fix some other problems by removing - "const" from all the methods... - -Wed Aug 16 22:26:24 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Thread_Specific.h: Fixed another stupid bug - caused by a braino that failed to unconditionally include - Thread_Specific.i. Stuart Powell found this also... (thanks!). - - * libsrc/Threads/Thread_Specific.h: In Thread_Specific.h the - inlining macros were only included if threads were used. This - obviously didn't work for people without threads... I - moved the #endif for ACE_HAS_THREADS... back before the #ifdef - __INLINE__ stuff (e.g. to line 71). Thanks to Stuart Powell - (stuartp@ot.com.au) for suggesting this. - - * libsrc/Threads/Synch.h: Fixed a typo that manifested itself for - pthreads: Condition count_nonzero_ should obviously be - Condition<Mutex> count_nonzero_. Thanks to Rob Clairmont - (rclairmo@bnr.ca) for reporting this. - -Tue Aug 15 00:31:44 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Log_Msg/Log_Msg.C (log): Fixed a stupid typo (*format++ - should have been format++...). - - * libsrc/Misc/Trace.h: Move the class TSS_Int from within class - Trace to file scope and changed the name to ACE_TSS_Int to - handle problems with the HP/UX compiler. - - * include/ace/sysincludes.h: Added the word "struct" in front - of rusage to make things work on HP/UX. Thanks to Neil Cohen - (nbc@metsci.com) for reporting this fix. - - * apps/TokenServer/server/TokenMap.C: Fixed yet another problem - with scope of variables defined in for loops... - - * Released new version of ACE 3.2.9... - - * libsrc/Connector: Fixed a braino whereby I didn't use consistent - naming for my #defines (PA should have been PRC). Thanks to - Alex (alexey@ace.elektra.ru) for noticing this. - -Mon Aug 14 18:13:46 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/SPIPE_Acceptor: Modified the interface of open() - and accept() so they would conform to the SOCK_Acceptor and - TLI_Acceptor. This makes it possible to use SPIPE_Acceptor in - similar situations (e.g., Acceptor and Connector patterns). - - * libsrc/ASX/Stream: Fix a bug that occurred when trying to dump() - a linked Stream. - - * libsrc/Connection/Acceptor: Moved the body of the init() method - out of this class since it was unnecessarily dependent on the - INET_Addr domain addressing types. This required changes to the - ./apps and ./tests directory in order to add the init() method - to classes that used the default behavior. - - * libsrc/IPC_SAP/SPIPE_SAP/SPIPE_Acceptor.C: Fixed close() so that - it will call fdetach(2) *before* closing down the descriptor. I - hope this will fix a problem noticed by people at SIEMENS. - - * tests/ASX/Event_Server/Event_Server/Options: Fixed a problem - with the default port numbers (they weren't using the values - from ./include/ace/testconfig.h). - - * include/ace/sysincludes.h (MAXNAMELEN): If MAXNAMELEN is not - defined by a platform then ACE sets it to be FILENAME_MAX, - which should be defined in stdio.h. Thanks to Todd Blanchard - (tblancha@evolving.com) for this suggestion. - -Sun Aug 13 17:02:57 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Service_Configurator/Parse_Node: Changed the name of - Function_Node::symbol (const void *) so that it won't give - those annoying warnings anymore... - - * libsrc/Reactor/Handle_Set: Moved the definition of MSB_MASK from - the header file into a static const within the .C file in order - to avoid overflow problems on certain compilers. - - * libsrc/Threads/Synch: Implemented bare-bones versions of - Semaphore and RW_Mutex for the POSIX Pthreads wrappers so that - they'll be more compatible with the Solaris threads wrappers. - The semaphore implementation uses a Condition object and a - Mutex, which should be a reasonable solution. The RW_Mutex is a - cop-out for now and just uses a Mutex (i.e., no extra - parallelism for readers...). If anyone has a good - implementation of RW_Mutex that they'd like to share please let - me know. - - * libsrc/Threads/Thread_Specific: Fixed the prototypes for copy - constructor and operator=, which were broken... Thanks to Alex - (alexey@ace.elektra.ru) for noticing this. - - * libsrc/Shared_Malloc/Memory_Pool.C: Added some casts to - MAP_FAILED to handle OSF/1. Thanks to Alex - (alexey@ace.elektra.ru) for noticing this. - - * libsrc/Threads/Token: Fixed things so that threads waiting for a - token wouldn't get screwed up by signals that occur... - - * include/ace/sysincludes.h: Changed the #ifdef - ACE_SELECT_USES_LONG to ACE_SELECT_USES_INT for HP/UX since - believe it or not, it really does use int, not long! - - * libsrc/SV_Semaphores: Fixed some weird problems that the HP/UX - compiler was having when trying to inline methods in this class. - As a consequence, I've rearranged the class to avoid inlining - non-trivial methods. Thanks to John Morey (jmorey@hitel.com) - for reporting these problems. - -Wed Aug 9 01:29:16 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Token: Added a tryacquire() method to become - interface compliant with other LOCK mechanisms. - -Sat Aug 5 09:18:29 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Connection: Fixed a couple of bugs when using - the Acceptor and Svc_Handler when ACE_OMIT_SERVICE_CONFIGURATOR - is enabled. Thanks to Stuart Powell (stuartp@ot.com.au) for - bringing this to my attention. - - * include/ace/sysincludes.h: Added a #ifdef for MAXNAMELEN to - handle systems (like HP/UX) that don't support it. - -Thu Aug 3 22:59:13 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released new version of ACE 3.2.9... - - * libsrc/Reactor/Time_Value.i (normalize): Added new code to - perform normalization of Time_Values. Thanks to Hans Rohnert - (Hans.Rohnert@zfe.siemens.de) of SIEMENS for the suggestion. - -Tue Aug 1 00:19:00 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Changed all code that used Log_Msg::log() directly to use - LM_ERROR or LM_DEBUG. This will ensure that logging will work - with the new thread-specific storage implementation. - - * libsrc/Threads/Thread_Manager.i (open): Fixed this method so - that it is thread-safe when a Thread_Manager is resized. - - * libsrc/ASX/Map_Manager.i (open): Fixed this method so that it is - thread-safe when a Map_Manager is resized. - -Mon Jul 31 12:56:17 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Misc/Trace: Reimplemented the ACE Trace class to use the - new thread-specific storage wrapper. - - * libsrc/Log_Msg: Reimplemented the Log_Msg class to use the new - thread-specific storage wrapper. This shouldn't affect any - existing code that was careful to only use the LM* macros... - - * libsrc/Threads: Added a new class called Thread_Specific which - implements a C++ wrapper for SunOS 5.x thread-specific data - (this will also work for POSIX pthreads I believe). Thanks to - Tim Harrison (harrison@cs.wustl.edu) for coming up with the idea - for using C++ "smart pointers" to implement this. - - * libsrc/Reactor/Timer_Queue.h: Moved Timer_Node from within - Timer_Queue to outside Timer_Queue and renamed it to - ACE_Timer_Node. Unfortunately, some compilers still don't like - nested classes (ugh)... - - * Changed ACE_Synch_Options to be simply Synch_Options since it - is *not* an ACE private class... - -Sun Jul 30 00:07:28 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * include/makeinclude/README: Added a new #define called - ACE_HAS_THREAD_SPECIFIC_STORAGE, which does exactly what it - sounds like! So far, I know that Solaris defines this. I'm not - sure which other platforms do (perhaps OSF/1 does?). - -Fri Jul 28 14:53:45 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Fixed a bunch more problems with loop variables that were - uncovered with GCC 2.7. Thanks to Matt Stevens - (mstevens@ent.mrj.com) for noticing this. - - * apps/Logger/Service_Configurator_Logger: Added a new flag called - ACE_HAS_NO_STATIC_DATA_MEMBER_TEMPLATES which is necessary to - workaround bugs with GNU G++... Thanks to Matt Stevens - (mstevens@ent.mrj.com) for noticing this. - - * libsrc/Connection/Connector.C (cleanup_AST): Changed the - parameter list just a tad to try and fix a problem with - G++ (which doesn't seem to like unscoped typedefs in - argument lists or return values. - - * libsrc/Misc/Profile_Timer.i: Changed ::getrusage to be getrusage - to avoid problems with macros and scope operators... - - * include/ace/testconfig.h (ACE_DEFAULT_RENDEZVOUS): Changed the - value from /tmp/foo to /tmp/fifo.ace. Thanks to Neil B. Cohen - (nbc@metsci.com) for suggesting this. - -Thu Jul 27 12:30:06 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/TokenServer/server/TokenHandler.C (abandon): Fixed a minor - bug that caused assert() to fail when a client abandoned a - Token. - - * libsrc/Reactor: Fixed a bug with the design of the Reactor's - Timer_Queue cancellation mechanism. The new mechanism is much - more robust since it ensures that timer_ids (used to cancel - pending timers) are unique up to values of greater than 2 - billion timers! As long as timers don't stay around longer than - this there should be no problems with accidentally deleting the - wrong timer. Thanks to Bill Sears (wsears@world.std.com) for - noticing this problem. - - One nice consequence to this change is that legacy code that - would have broken with the previous change is now 100% - compatible! - - * Provided a definition of ACE_Synch_Options::arg(const void *), - which I'd forgotten to define before (darn templates...). - Thanks to Tim Harrison (harrison@cs.wustl.edu) for finding this! - - * include/ace/sysincludes.h: Added a total hack to get HP/UX to - understand getrusage(). The trick is to use the following - undocumented syscall: - - #define getrusage(a, b) syscall(SYS_GETRUSAGE, a, b); - - What a hack (but it works...). - -Tue Jul 25 13:20:58 1995 Douglas C. Schmidt (schmidt@kavita.cs.wustl.edu) - - * libsrc/Misc/Profile_Timer: Fixed a typo in Profile_Timer.h - (ACE_HAS_RUSAGE_T should have been ACE_HAS_GETRUSAGE). Thanks - to George Reynolds (george@dvcorp.com) for noticing this. - - * Changed all uses of ::getopt() to use the ACE class Get_Opt - get_opt. Also changed all uses of optarg to get_opt.optarg. - Thanks to Bob Vistica (robertv@ims.com) for detecting and - reporting some inconsistencies in my previous changes... - -Mon Jul 24 19:03:03 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * include: I've added config and platform support for SGI IRIX5.3 - for use with the SGI C++ compiler. Thanks to Stuart Powell - (stuartp@ot.com.au) for these config files. - - * libsrc/Connection/Acceptor.C (handle_input): Added the - Event_Handler::DONT_CALL flag when removing the Oneshot_Acceptor - from the Reactor so that we don't set it's peer_acceptor_ to -1. - -Mon Jul 24 12:46:10 1995 Douglas C. Schmidt (schmidt@kavita.cs.wustl.edu) - - * libsrc/Misc/Profile_Timer: Fixed problems stemming from the fact - that HP/UX doesn't seem to support getrusage() (how odd). - - * tests/Connection: a new test directory to test out the Connector - and Acceptor pattern implementations. - -Sun Jul 23 12:26:37 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Connection/Acceptor.C: Fixed a minor bug with the - Oneshot_Acceptor constructor. Thanks to John Morey - (jmorey@hitel.com) for noticing this and the one below. - - * libsrc/Reactor/Timer_Queue: Moved the static method current_time - from the Timer_Queue.i file to the Timer_Queue.C file. This - avoids a bug with HP/UX C++. - -Sat Jul 22 15:54:27 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released beta version 3.2.9. Once this compiles on all major - platforms then it's time to move to version 3.3. - - * Added a number of miscellaneous changes for OSF/1 courtesy of - David Trumble (trumble@cvg.enet.dec.com). One of these changes - involved changing all uses of Reactor::{ADD,SET,CLR,GET} to - Reactor::{ADD,SET,CLR,GET}_MASK in order to avoid a class with - some symbols in OSF/1. - -Fri Jul 21 00:21:02 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Finally was able to test ACE on the SunOS 4.x platform (using - the SunC++ 4.0.1 compiler). The entire release compiled - correctly! This is a great relief after fighting with this - stuff for months... If you are building ACE on SunOS 4.x I'd - *strongly* recommend you get SunC++ 4.0.1 since it is the only - compiler that seems to be able to grok the weirdness of SunOS - 4.x... - - * Finished updating all the ./tests and ./apps code so that it - works correctly with the new Acceptor/Connector modifications. - To see examples of these changes check out - ./tests/IPC_SAP/SOCK_SAP/CPP-{nbclient,inserver}.C. - - * libsrc/Misc/Profile_Timer: Merged in the new Profile_Timer - implementation from David Trumble (trumble@cvg.enet.dec.com). - This will work with basically the same interface as the current - scheme even if the OS platform doesn't support the prusage_t - type... - -Thu Jul 20 01:07:23 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Connection: Added a new class called ACE_Synch_Options - which is used in both the Acceptor and Connector classes to - consolidate options related to synchronous and asynchronous - behavior. - - * libsrc/Connection: Added a new class called Oneshot_Acceptor. - This class inherits from the Acceptor but it only accepts one - connection at a time (i.e., it doesn't keep itself registered - with the Reactor). Several examples in the tests/SOCK_SAP - directory have been added to illustrate how all this works. - - * libsrc/Connection/Connector: completely redid the Connector and - Acceptor class interfaces to incorporate the new changes for - asynchronous and synchronous behavior. The new scheme should be - much more general (and correct...). Thanks to Tim and Irfan for - helping out with this. - - * libsrc/Threads/Synch: Fixed the implementation of Recursive_Lock - so that it won't have race conditions when testing the thread id - and nesting level in parallel threads. - -Wed Jul 19 13:15:05 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Timer_Queue: Added new support for cancellation - of individual Event_Handlers in the Reactor. In addition, it is - now possible to cancel all Event_Handlers with a single call to - Timer_Queue::cancel(). Note that this new scheme will break - existing code since Timer_Queue::schedule() (and - Reactor::schedule_timer()) now return ACE_Timer_Node *'s rather - than ints... - - * libsrc/Service_Configurator/Service_Config: Fixed a problem - where the "-s" option didn't work since it was parsed when - "Service_Config::open" was called - (it sets Service_Config::signum_). However, previously the - signal handler was already setup by the constructor. By moving - this registration to the open() method the problem was solved. - Thanks to Bob Vistica (robertv@ims.com) for noticing this. - - * libsrc/Service_Configurator/Service_Manager: Changed the - Service_Manager::reconfigure_services to use this->signum_ - rather than to hard code SIGHUP. Thanks to Bob Vistica - (robertv@ims.com) for this insight. - -Mon Jul 17 12:08:08 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Threads/Token.C (renew): Fixed a typo so that we compare - this->head_ == 0 rather than this->head_->next_ == 0. - - * libsrc/Reactor/Reactor.h: Changed the Reactor to use the - Reactor_Token rather than the pure Token to make sure that the - sleep_hook() is called to unblock the Reactor. - -Fri Jul 14 14:12:07 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Connection: Changed the default behavior of the Connector - and Acceptor classes such that they pass a -1 to - svc_handler_->close() when things go wrong. This is useful as a - flag to close() (e.g., if it needs to figure out what to do if - is shuts down prematurely). - - * libsrc/Connection/Svc_Handler.C: Added a default definition of - the put() method, which is defined as a pure virtual method in - class Task. - -Thu Jul 13 23:10:35 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * include/ace/sysincludes.h: Added support for the SGI IRIX 5.3 - OS. More screwy gettimeofday() hacks (what a pain...). Thanks - to Matt Stevens (mstevens@kirk.softeng.infonautics.com) for - these fixes. - - * include/makeinclude/platform_sunos5_centerline.GNU: Fixed a - vexing problem that was causing the Centerline C++ compiler to - puke when compiling ACE. Thanks to Chandra Venkatapathy - (cvenkat@develop.bsis.com) for finding a solution! - -Tue Jul 11 00:01:15 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 3.2.6 for use by Karl and Detlef. - -Mon Jul 10 00:28:51 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/TTCP: Added support for benchmarking the performance of - Orbix, ORBeline, ACE SOCK_SAP, and C sockets. These results are - available at URL http://www.cs.wustl.edu/~schmidt/COOTS-95.ps.Z - - * libsrc/Service_Configurator/Makefile: Added new commands to the - Service Configurator Makefile so that all automatically - generated flex and yacc symbols (i.e., the "yy" stuff) is - renamed "ace_yy". The purpose is to avoid conflicts with other - uses of flex/yacc lexers/parsers with ACE. Thanks to Steve - Ritter (ritter@titan.com) for this suggestion and code. - - * libsrc/IPC_SAP/TLI: Changed the TLI files so they are - conditionally compiled only if the platform supports TLI... - - * libsrc/Connection: Changed the inlining strategy of Connector, - Acceptor, and Svc_Handler so that very short methods are always - inlined, but anything larger is never inlined... - -Sun Jul 9 14:07:02 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * include/ace/testconfig.h: Changed all occurrences of DEFAULT_* - to ACE_DEFAULT_ to prevent namespace collision. - - * libsrc/Connection/Connector: Massively improved the Connector - class so that its connect() method supports the following - behavior (tv == "timeout value" and ur == "use Reactor"): - - Parameters | Description - | - tv | ur | - -----|----------|------------------------------- - | | - NULL | yes | infinite timeout (using Reactor) - | | - time | yes | try asynch transaction for - | | the specified time (using Reactor) - | | - 0,0 | yes | poll; try, if EWOULDBLOCK, - | | then return immediately - | | (using Reactor) - | | - NULL | no | block forever (don't use Reactor) - | | - time | no | do a blocking transaction - | | for the specified time - | | (don't use Reactor) - | | - 0,0 | no | poll; but do not initiate a - | | nonblocking transaction - | | (don't use Reactor) - - * libsrc/IPC_SAP/SOCK_SAP/SOCK_Connector: Changed the behavior of - the SOCK_Connector::connect() method so that it uses Time_Values - rather than a simple flag that indicates whether or not to use - non-blocking connectors. The new scheme is an improvement since - it allows greater control over synchronous and asynchronous - timeouts for connection establishment. This behavior parallels - that of SOCK_Acceptor, as well! If this works well then I'll - update the TLI_Connector and SPIPE_Connector to match this - interface. - - * libsrc: Continued to improve ACE's use of the global name space - by prefixing all "helper" classes with "ACE_" - - * Updated SPIPE_Acceptor so that it would have the same basic - interface as the SOCK_Acceptor and TLI_Acceptor. - - * libsrc/IPC_SAP: Consolidated the handle_timed_wait() methods - used by the TLI, socket, and STREAM pipe wrappers so that they - share the new ACE::handle_timed_accept() method, which is in - libsrc/Misc. - - * libsrc/Misc: Modified the structure of Misc.[Ch]. Originally, - this file contained a bunch of stand-alone C functions with the - prefix "ace_" to keep them from conflicting with user's code. - I've modified things now so that all the miscellaneous functions - are now static methods in class ACE. This provides better scope - control... - - * libsrc/Log_Msg/Log_Msg: Replaced the use of a Mutex in class - Log_Msg with a Recursive_Lock<Mutex>. This is necessary to - handle signals correctly... - - * libsrc/Reactor/Reactor: Modified the behavior of - Reactor::notify() so that writers will block if the pipe is - full. This solves some nasty flow-control problems. - - * libsrc/Reactor/Handle_Set: changed all uses of fd_set to - ACE_FD_SET_TYPE * so that HP_UX would work correctly... - - * include/ace/config-hpux.h: Removed the ACE_HAS_XLI flag until I - get a better idea which HP systems this is installed on. - - * libsrc/Threads/Thread: Added a new static method called - spawn_n() that spawns "n" threads all running the same function. - -Sat Jul 8 14:14:34 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Service_Configurator: Made some miscellaneous changes to - "const" methods and parameters in order to handle the new - Reactor changes (C++ can be such a pain about this - sometimes...). - - * libsrc/Threads: Added "yield" and "sigsetmask" methods to class - Thread. How did I manage to omit these before?! - - * libsrc/Reactor: Updated the Reactor to use the new Token class - described below. This greatly simplies the structure of the - multi-thread support in the Reactor code. In addition, it - should improve performance because it cuts the number of context - switches compared with the old scheme. Many thanks to - Karl-Heinz and Detlef for encouraging me to redo the Reactor - implementation. - - * libsrc/Threads: Added a new class called Token that provides a - flexible and efficient recursive mutex scheme. Thanks to - Karl-Heinz Dorn (kdorn@erlh.siemens.de) and Detlef Becker - (beckerd@erlh.siemens.de) for sharing their original code for this. - -Thu Jul 6 10:37:45 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Event_Handler_T: Conditionally compiled this so - that it will only compile if the compiler supports template - typedefs (e.g., G++ doesn't seem to like this...). - - * Started to make changes in ACE to deal with the new ANSI C++ - semantics in the scope of variables defined within for loops. - Thanks to Aniruddha Gokhale (gokhale@cs.wustl.edu) for noticing - this in G++ 2.7... - -Wed Jul 5 21:50:39 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Connection/Svc_Handler: Fixed the behavior of the - Svc_Handler class so that it can be configured with a Reactor - other than Service_Config::reactor, just like the Acceptor and - Connector. Thanks to Karl-Heinz Dorn (kdorn@erlh.siemens.de) - for suggesting this! - -Tue Jul 4 00:21:31 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added some new changes for Linux courtesy of Charles Rennolet - (clr@thurse.mn.org). - - * libsrc/Reactor/Reactor.C (bit_ops): Fixed a dumb error in - bit_ops that was caused by checking "else if (Reactor::SET)" - rather than "else if (ops == Reactor::SET)". Thanks to Mark - Patton (mark_patton@tx72.mot.com) for finding this bug and - reporting it along with the fix. - - * include/ace/sysincludes.h: Added new fixes for M_SYNC and - ENOTSUP on SunOS 4. - - * libsrc/Reactor: Added new support for integrating X and the - Reactor. These files are called XtReactor.* and XReactor.*. - Thanks to Eric Vaughan (evaughan@arinc.com) for providing this - stuff... - -Mon Jul 3 19:44:07 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added support for SunOS 5.5 on i86 PC. Thanks to Bin Mu - (mubin@wfg.com) for the config files and fixes. - - * libsrc/Misc/Profile_Timer: Added new support for versions of - UNIX that don't support prusage_t. The new version of - Profile_Timer will use gettimeofday() and getrusage() of - prusage_t and /procfs isn't available... This code hasn't been - tested yet (since I don't have SunOS 4.x) so I don't know if it - works. - - * Hopefully fixed the SunOS4 prototype for gettimeofday(). Thanks - to Andrew McGowan (ajm@se09.wg2.waii.com) for the suggested fix. - - * include/makeinclude/platform_hpux.GNU (CC): Added new support - for building ACE and shared libraries on HP/UX. Thanks to Jam - Hamidi (jh1@osi.com) for this code. - - * libsrc/Reactor/Handle_Set: Fixed Handle_Set_Iterator::operator++ - to check for index to be greater or equal than NUM_WORDS instead - of just equal. This is better for sanity, although it may not be - needed. Thanks to Carlos Garcia Braschi (cgarcia@caramba.tid.es) - for suggesting this fix. - -Wed Jun 14 11:16:40 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/TLI_Acceptor: modified TLI_Acceptor so that it's - public constructor/open() and accept() methods are more similar - to the SOCK_Acceptor. In particular, added support for - "SO_REUSEADDR" in TLI_Acceptor and time values for accept(). - Thanks to John P. Hearn (jph@ccrl.nj.nec.com), TLI_SAP now does - the right thing for socket options. - - * libsrc/IPC_SAP: Fixed up the SOCK_Acceptor and TLI_Acceptor in - order to add better support for "timed accepts." The new scheme - uses Time_Values, which is more consistent with other parts of - ACE. In addition, the Time_Value was moved from the - constructor/open() to the accept() method, which allows more - fine grained control over this behavior. Thanks to Irfan - (ip1@cs.wustl.edu) for suggesting this. - - * libsrc/IPC_SAP: Cleaned up the SOCK_Acceptor::open and - TLI_Acceptor::open routine. In addition to being more compact - and robust, this routine now also let's open() determine which - local port to bind to (if you pass in Addr::sap_any as the - local_addr). Thanks to Irfan (ip1@cs.wustl.edu) for suggesting - this. - -Tue Jun 13 16:09:13 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Timer_Queue: Fixed an odd problem with the - Timer_Queue on Solaris. Apparently the select() call will - return slightly earlier than the timeout dictates due to lack of - granularity with the system clock. This was causing problems - where the Reactor wasn't correctly dispatching the - handle_timeout() method of Event_Handlers. The fix was to add a - 10 Millisec "fudge factor" when calling the - Timer_Queue::expire() method. Please let me know if this causes - any problems. Thanks to Giang Hoang Nguyen - (yang@titan.com) to noticing this problem. - - * libsrc/Connection/Acceptor: Enhanced the Acceptor class so that - it is possible to accept a new SVC_HANDLER synchronously, rather - than always driving this acceptance out of the Reactor's event - loop. Thanks to Irfan (ip1@cs.wustl.edu) for suggesting this. - - * libsrc/IPC_SAP/Addr: Changed all occurrences of ace_sap_any to - Addr::sap_any (i.e., sap_any is now a static data member in - class Addr). This is an improvement since it helps to limit the - scope of what would otherwise be global variables... - -Wed Jun 7 17:26:31 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * apps/Logger/Reactor_Logger/Client_Acceptor.i (handle_input): - Fixed a braino that omitted an important block of code! Thanks - to Ken Konecki (kenk@wfg.com) for finding this. - -Fri Jun 2 13:59:07 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/Addr/INET_Addr.i (set): Removed the special case - for INADDR_ANY. This should just fall right out... - -Thu Jun 1 19:45:21 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/SOCK_SAP/SOCK_Connector: Added support to - SOCK_Connector so that it is possible to bind the local TCP port - number prior to establishing the connection. Also fixed the - TLI_Connector to be consistent with this approach. Thanks to - Mark Patton (mark_patton@tx72.mot.com) for this idea. - - * Fixed a problem with Mem_Map that was caused by the fact that - some versions of Unix (e.g., SunOS 4.x) don't support MS_SYNC... - Thanks to Andy McGowan (mcgowan@wg2.waii.com) for noticing this. - - * Fixed a very stupid bug in ./libsrc/Synch.h that accidentally - omitted this->lock_.acquire() from the Guard class constructor. - Thanks to Bin Mu (mubin@wfg.com) for noticing this! - -Fri May 26 13:20:38 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Connection/Acceptor: Added a new method called - make_svc_handler() that generalizes the dynamic creation of a - SVC_HANDLER by the Acceptor's Template Method handle_input(). - This scheme is completely backwardly compatible with the - original approach, but now allows transparent extension too! - - * libsrc/Connection/Acceptor: cleaned up the Template Method logic - in Acceptor::handle_input. No longer do we set the listener - socket into non-blocking mode and then rely on a -1 with - EWOULDBLOCK to indicate there are no more connections to - establish. This was causing problems for singleton Svc_Handlers - since the Acceptor was setting their peer_stream_ to -1... The - new approach should complete solve this problem. - -Mon May 22 15:10:27 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 3.2.3 so that Bill Sears can test the new - #include "ace/" features. - - * Modified all the ACE source, tests, and apps so that all - #includes of its headers are refixed by ace/, e.g.: - - #include <ace/Reactor.h> - - There are two reasons for have the include files be of - this form: - - First, you can tell at a glance by looking at the caller where - the library is coming from. - - Secondly, you can build an include tree of the form: - - /include/lib1 - /include/lib2 - /include/lib3 - /include/ace - - which then links to WRAPPER_ROOT. Now, all you have to do - when you build a make file is point to the include root, and - put links in the include root. This is especially helpful - if there are multiple versions. - - This means just one less thing that has to be modified in the - Makefile. Thanks to Bill Sears (wsears@world.std.com) for - recommending this change. - -Sat May 20 17:12:35 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * config-irix5.3-sgic++.h: Added new configuration support for SGI - IRIX5.3 courtesy of Stuart Powell (stuartp@ot.com.au). - -Sat May 13 20:44:06 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Generalized the SOCK_Connector::complete method so that it takes - a Time_Value timeout. This allows applications to wait upto a - certain limit before giving up on a non-blocking connection. - Updated the tests in ./tests/IPC_SAP/SOCK_SAP/CPP-inclient.C to - illustrate how this is used. - - * Added some interesting new tests to ./tests/Mem_Map that can be - used to benchmark the performance of various strategies (e.g., - stdio, read/write, mmap, etc.) for copying files. - -Fri May 12 19:09:10 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Mem_Map/Mem_Map: Added two new overloaded methods called - sync() that are wrappers around the msync(3c) system call. Also - added a new unmap() method that gives access to the full - behavior of munmap(3c). - -Wed May 10 14:16:16 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Tried yet another fix for the gettimeofday() botch that both - Centerline and SunOS 5.4 screw up in different ways. Thanks to - Medhi Tabatabai (Mehdi.Tabatabai@ed.nce.sita.int) for the latest - fixes. - -Tue May 9 19:05:58 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Handle_Set.C: Fixed some "off-by-one" errors that - were occurring in the Handle_Set::sync() and set_max() methods. - Thanks to Nigel Hooke (n.hooke@trl.oz.au) for finding and fixing - these. - -Mon May 8 02:01:54 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Reactor.C: Moved the Null_Callback class from - being nested within the Reactor class to outside the Reactor - class. This fixes a problem with the SIG compiler. - - * Released version 3.2.2. - - * libsrc/Reactor/Signal.C: Made the Signal_Handler class - thread-safe as well as signal-safe. - - * libsrc/Reactor/Reactor.C: Modified the new Reactor - implementation slightly to handle signals correctly. - - * libsrc/Threads/Synch.h: Added a new conversion operator to - Recursive_Lock that returns the underlying LOCK in case we need - it for something (e.g., to initialize a Condition object). - -Sun May 7 04:17:46 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Reactor.C: Finished what I hope will be the last - set of changes to make the Reactor robust in multi-threaded - programs in situations where separate threads are used to - register and remove handlers. The final solution is elegant in - that it does not significantly penalize the performance of - programs that do not use separate threads to register and remove - handlers. Moreover, if you compile without the ACE_MT_SAFE flag - the Reactor will not include additional state information - related to the multi-threaded implementation. - - * libsrc/Threads/Synch.h: Subclassed the Guard class to make a new - class Try_Guard that uses tryacquire() to obtain a LOCK. - -Fri May 5 18:43:50 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Released version 3.2.1 - -Thu May 4 19:43:01 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/TLI_SAP/TLI_Connector.C (connect): Fixed a - problem whereby a t_bind() was being done twice. Since I didn't - write this code I don't know if my fix will work generically on - all platforms supporting TLI. Please let me know if there are - any problems. - -Tue May 2 17:21:53 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor: Added a new notification feature that allows - multiple threads of control to enqueue Event_Handler * to the - main Reactor thread via the pipe used to wake up the main - Reactor thread. The Reactor will call the handle_exception() - method on Event_Handler with a HANDLE == -1 to notify the - handler. This feature is very useful if you need to have - certain operations (such as handler termination) performed in - the main thread. - -Tue Apr 25 00:34:18 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor: Fixed a stupid pair of typos in the Reactor that - failed to cast arguments to the pipe to char *. - - * libsrc/Connection: Fixed a portability problem with the - Connector: we can't use RW_Mutex for synchronization since not - all platforms support threads. The quick fix is to use - Null_Mutex, but a better long term approach is on the way! - - * Released version 3.2. - - * Added richer support for the TLI_Connector to make it work - better with protocols other than TCP/IP. Thanks to Mats - Sundvall (sundvall@perrier.embnet.se) for these enhancements. - -Mon Apr 24 02:26:04 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Changed the SOCK_Dgram_Brdcast class name to SOCK_Dgram_Bcast - and the SOCK_Mcast to SOCK_Dgram_Mcast to be more consistent. - - * Massively improved the Reactor's support for multi-threading. - There was actually a major problem in previous versions of ACE - that used poll() as the underlying event demultiplexor. Poll() - produced incorrect results when the Reactor::handle_events() - method was run in one thread, but another thread came along and - registered or removed an Event_Handler. The new version fixes - this problem so that the Reactor will now work correctly in - multi-threaded programs. - - One consequence of this change is that sysincludes.h and the - SunOS 5.x configuration files have been changed so that poll() - is no longer used as the default demultiplexor. The reason is - that poll() doesn't work as efficiently when used in - multi-threaded programs (ugh). See the Reactor code for - examples of how this all works now. Basically, the trick is to - use the select()-style implementation for most of the code, and - transform to poll()-style implementation only when necessary. - -Sat Apr 22 03:35:51 1995 Douglas C. Schmidt (schmidt@lambada.cs.wustl.edu) - - * libsrc/ASX/Message_Queue: Added a new method to the - Message_Queue class called unblock(). This method allows one - thread to release all other threads that are waiting for - messages to be enqueued or dequeued on a Message_Queue. - Modified the return value of methods like enqueue_head() and - dequeue_head() so that if a thread unblocks() then these methods - return -1 with errno == ESHUTDOWN. Also changed the name of - some of the internal methods so that they would be more - consistent. - - * libsrc/Connection/Connector: Fixed a stupid bug caused by - failing to have a destructor for Connector. Thus, there are - cases where unconnected Svc_Handlers are left around in the - handler_map_. This causes problems for dynamic linking in - conjunction with the Reactor, so now the destructor iterates - through all the unconnected Svc_Handlers and removes them from - the Reactor. - -Fri Apr 21 15:28:46 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Signal: Changed Sig_Set::addset() and - Sig_Set::delset() to the more appropriately named sig_add() and - sig_del(). Also added '_' in the Sig_Set method names to be - more consistent... - - * Removed the ./libsrc/IPC_SAP/SOCK_SAP/misc.[hC] file and merged - the one function in that file (ace_bind_port) into - ./libsrc/Misc/Misc.[hC]. - - * Added a bunch of fixes from various people to make ACE compile - better on SGI, SunOS 4, and HP/UX. Thanks for all the fixes! - - * libsrc/IPC_SAP/Addr: Changed sap_any to ace_sap_any to avoid - problems with the namespace. - - * Added a new portability flag that only compiles the SOCK_Mcast.* - stuff if the platform supports multicast! - - * ./libsrc/Shared_Malloc: Fixed some portability bugs with - Memory_Pool.C and added new support for SunOS 4.x running SunC++ - 4.x. Thanks to Steve Warwick (swarwick@arinc.com) for this - strategic help. - -Wed Apr 19 09:05:43 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Fixed up the ./libsrc/CORBA_Handler so that it will correctly - compile on platforms that don't have Orbix... - - * libsrc/Misc: added a new "Simple String" class called SString. - This is not really meant to be used by end-user applications. - It is used by certain portions of ACE that need to have - operator== and operator!= defined on a string (e.g., the - Token_Server and the Orbix Event_Comm components that use the - Map_Manager). - -Tue Apr 18 00:09:31 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/ASX: Fixed a stupid bug in Task::activate() that didn't - spawn a thread if the Thread_Manager was NULL... - -Sat Apr 15 19:39:30 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor: Added a new class to the Reactor called - Event_Handler_T.[hi]. This class makes it easy to integrate - existing classes into the Reactor framework without requiring - them to inherit from Event_Handler directly. This technique is - a superset of the DEF_TIE approach used by IONA in Orbix as one - of the ways to combine an existing class (that doesn't know - anything about CORBA) with a CORBA interface. Thanks to Greg - Lavender - (g.lavender@isode.com) for the suggestion. - -Fri Apr 14 14:41:49 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Run catman on the ./man directory so that it now has a windex - file. This facilitates "man -k". - -Thu Apr 13 23:39:22 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor: Made the Reactor be a stand-alone component that - does not require any other ACE libraries. - - * Added two new methods to the Reactor so that you can now - register or remove a set of HANDLEs in a single call. Thanks to - Bill Sears - (wsears@world.std.com) for this suggestion. Basically, now you - can register or deregister a set of n HANDLEs with one operation - (rather than doing n register_handler () or n remove_handler - ()). - - * include/sysincludes.h: Changed the name of the macro MT to - ACE_MT and DB to ACE_DB to avoid polluting the namespace. - -Wed Apr 12 11:14:46 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Reactor.C (close): Added code to close down the - pipe handles when the Reactor is shut down. Thanks to Mark - Patton (mark_patton@tx72.mot.com) for this info. - -Fri Apr 7 18:33:30 1995 Douglas C. Schmidt (schmidt@siesta.cs.wustl.edu) - - * Added a new method to CORBA_Handler so that handlers don't need - to subclass from CORBA_Handler, but rather can call the - CORBA_Handler::register_service() method (which is static). - Thanks to Chris Tarr (ctarr@objectspace.co) for this suggestion. - -Mon Apr 3 13:09:45 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added a new static method to Service_Config.[hC] called - end_event_loop(). This can be used to stop the run_event_loop() - method of the Service_Config. In addition, all the methods in - Service_Config were changed to be static to emphasize the fact - that the Service Configurator is a singleton... - - * include/Trace.h (ACE_TRACE): Changed the macro T to ACE_TRACE. - This will prevent namespace pollution. - - * Added support for the Orbix CORBA implementation. If you don't - have Orbix, you'll need to remove this flag from the - config-sunos5-sunc++.4.x.h file if you are compiling on SunOS - 5.x. - -Sun Apr 2 01:12:19 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added new support for C++ wrappers around the IP multicasting. - There are three new files in ./libsrc/IPC_SAP/SOCK_SAP called - SOCK_Mcast.[hiC] and a new test directory in - ./tests/Reactor/multicast and ./tests/Reactor/ntalker to - illustrate how to use this stuff. Thanks to Tim Harrison - (harrison@cs.wustl.edu) for this code. - -Sat Apr 1 18:48:40 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added support to the libsrc/Shared_Malloc/Memory_Pool.[hC] class - for System V shared memory, as well as for mmap(2) and sbrk(2) - memory. Please note that this has not been extensively tested - yet, so use with caution... - -Thu Mar 30 21:50:00 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Misc/Atomic_Op: Added the postfix versions of the ++ and - -- operators. This stops the Sun CC compiler from griping about - the "anachronistic" usage when using a++ rather than ++a. - Thanks to Bruce Worden <bruce@betsy.gps.caltech.edu> for the - suggestion. - -Wed Mar 29 22:26:37 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Handle_Set: Fixed a weird problem where I was - using NOFILE as the max number of descriptors rather than - FD_SETSIZE. I don't know why I was doing this. - - * Also fixed up a problem with Handle_Set that was causing the - iterator to go nuts when it got a strange initial value of - fd_set in Handle_Set. Orbix triggers this kind of nonsense in - some cases... - -Tue Mar 28 21:01:36 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/Reactor/Reactor.C: swapped the order of dispatching so - that handle_exception methods are dispatched before handle_input - methods to improve response time for exceptions (e.g., OOB - data). Thanks to Detlef Becker - (beckerd@erlh.siemens.de) for suggesting this. - - * Fixed a bug in ./ASX/Stream.i that caused problems when a Module - was popped off a Stream. Thanks to Paul Stephenson for noticing - this and sending me the fix. - - * Changed the Reactor::dispatch methods so that they dispatch the - timers *before* dispatching the I/O-based event handlers. This - is helpful for systems that are time-delay sensitive. - - * libsrc/Reactor/Time_Value: Added new += and -= operators to - Time_Value. Thanks to Alex V. Maclinovsky - (garyh@teleng1.tait.co.nz) for this suggestion. - -Thu Mar 23 15:38:23 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/Addr/SPIPE_Addr.i (set): Fixed a problem that the - HP/UX compiler had with complex arithmetic expressions. - - * libsrc/Service_Configurator: fixed up the Service_Configurator - source code so that it will compile correctly on HP/UX - platforms. - -Tue Mar 21 00:28:25 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * libsrc/IPC_SAP/SOCK_SAP/LSOCK_Connector.h: Fixed an amazingly - stupid bug with LSOCK_Connector, where I was passing in a - default argument of PF_INET instead of PF_UNIX... Arrgh! - -Mon Mar 20 20:24:29 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Fixed up the $WRAPPER_ROOT/include/makeinclude/ directory to - define a new set of platform-specific configuration files. This - should greatly improve the portability of ACE to different - OS/compiler platforms. - - * Added a bunch of changes to allow ACE to build with Lucid C++ on - SunOs 4.x. This should also fix some other problems we've been - having with SunOS 4.x. Thanks to Lee Baker (baker@ctis.af.mil) - for these changes. - -Sun Mar 19 00:34:30 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added manual pages for all of the ./libsrc libraries. These - manual pages are all generated automagically from the libsrc - header files. - -Sat Mar 18 10:48:46 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Finally broke down and fixed the Makefile scheme so that there - is just one shared library (libACE.so) and one archive library - (libACE.a). This should massively simplify the application - development process, though it may require a bit of fixing of - Makefiles to remove all the -lReactor -lIPC_SAP stuff that was - in there before. - - * libsrc/IPC_SAP/TLI_SAP/: Fixed a stupid bug that was causing - core dumps since the TLI option pointers weren't initialized to - 0 in the TLI::TLI constructor. Thanks to Ed Brown for noticing - this (eebrown@netcom.com). - -Wed Mar 15 00:08:19 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added some new fixes to get ACE to run on OSF1 and Linux. - -Tue Mar 14 13:36:31 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added several changes to the source code and config-hpux.h - configuration file based on comments from Alex Ranous - (ranous@nsa.hp.com). In particular, changed ACE_HAS_NO_FDSET to - ACE_SELECT_USES_LONG. - -Mon Mar 13 09:23:58 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Improved the Makefile scheme so that the use of PTDIRS is no - longer required. The trick was to link the appropriate template - *.C files into the WRAPPER_ROOT/include directory. This enables - the compiler to find them in one single place. - -Sun Mar 12 22:35:50 1995 Douglas C. Schmidt (schmidt@tango.cs.wustl.edu) - - * Added a new mechanism to clean up the insane number of -D's in - the Makefile. This new mechanism requires a bit more work at - installation time, but should greatly reduce the effort during - normal software development - (once ACE is installed...). See the INSTALL file - for more details. - -Fri Mar 10 17:29:02 1995 Douglas Schmidt <douglas@gtcterminator> - - * Fixed a stupid bug in Map_Manager.i which wasn't correctly - setting default values for fields in one of the Map_Manager - constructors. - -Fri Mar 10 08:54:42 1995 Doug Schmidt <douglas@gtccipher> - - * /libsrc/Connection/Acceptor.i: Fixed a potential memory leak in - handle_input(). - -Thu Mar 9 11:59:54 1995 Doug Schmidt <douglas@gtccipher> - - * Changed the Map_Manager::find() method to use class Read_Guard - so that multiple finds may proceed in parallel on a multiple - threaded application. Likewise, changed the implementation of - bind() and unbind() to use class Write_Guard so that destructive - operations will be serialized correctly. One consequence of - this is that RW_Mutex must be used instead of Mutex... - - * Added a new overloaded Map_Manager::unbind() method with an - INT_ID parameter. This parameter that passes back a reference - to the internal id being unbound. This allows the caller to - clean up any dynamic memory associated with the INT_ID. - -Tue Mar 7 13:32:17 1995 Doug Schmidt <douglas@gtccipher> - - * Changed a bunch more things to get ACE to compile with - Centerline C++. This should also make ACE more portable to - other cfront-based compilers. - - * Had to change the ASX source in ACE to work around a stupid - problem with templates in cfront-based C++ compilers. - Fortunately, it was possible to mask most of the problems using - the C++ preprocessor. - - * There seem to be some problems with cfront-based compilers (such - as centerline). They don't like the new SYNCH::MUTEX usage in - the Message_Queue. - - * Removed several unused local variables in the INET_Addr::set() - method. - -Wed Mar 1 00:35:11 1995 Douglas C. Schmidt (schmidt@tango) - - * Added a major performance boost on high-speed networks. It - turns out that send(3) and revc(3) are slower than write(2) and - read(2) (since the latter are system calls, and the former are - library calls. Therefore, I added new overloaded methods to - SOCK_IO so that write(2) and read(2) are available to the user! - -Tue Feb 28 10:13:09 1995 Douglas C. Schmidt (schmidt@tango) - - * libsrc/Reactor/Reactor.C: Fixed the implementation of the - Reactor::open and Reactor::Reactor constructor so that it is now - possible to resize the size of the Reactor *after* the - constructor has run (by calling open()) *without* having to shut - down the Reactor first. - - * Modified the Reactor::attach() method so that it will ADD the - new bits to the bitmask rather than SET them. Thanks to Mark - Patton for recommending this - (mark_patton@tx72.mot.com). - -Sat Feb 25 15:08:04 1995 Douglas C. Schmidt (schmidt@tango) - - * Released version 3.0.5. - -Fri Feb 24 17:57:01 1995 Douglas C. Schmidt (schmidt@tango) - - * Used the OSE class2man scripts to generate UNIX manual pages for - IPC_SAP, Thread, Connection, and Reactor. Other manual pages - will be forthcoming... - - * libsrc/IPC_SAP/Addr/INET_Addr.i: Fixed a bug in one of the - INET_Addr::set() methods that caused a segmentation fault if - host_name was NULL. In addition, greatly cleaned up the code so - that all the "set" methods share a common basis of code. - -Tue Feb 21 19:32:28 1995 Douglas C. Schmidt (schmidt@tango) - - * Updated the entire release to use the new SYNCH template - interface for Task, Module, Stream, and Message_Queue. This is - *much* cleaner, though it reveals some bugs with the Sun C++ - templates facility. - -Mon Feb 20 22:46:14 1995 Douglas C. Schmidt (schmidt@tango) - - * Changed the SPIPE_SAP, SOCK_SAP, and TLI_SAP *Connector class - methods from open() to connect(). This is a more accurate name - and it also fits in nicely with the Acceptor::accept() method. - - * Started integrating new versions of various header files that - include hooks to automatically generate documentation. - -Tue Feb 14 20:52:13 1995 Douglas C. Schmidt (schmidt@tango) - - * Changed the order in which the Reactor dispatches descriptors. - Originally, it dispatched the "read" descriptors *before* the - "write" descriptors. Now, it dispatches the "write" descriptors - first. This was necessary to handle weird behavior of sockets - over TCP/IP when data is piggy-backed with the final ACK on a - non-blocking connection. - -Mon Feb 13 15:49:21 1995 Douglas C. Schmidt (schmidt@tango) - - * Changed the name of Event_Handler::get_fd() to - Event_Handler::get_handle() to be more consistent with other - usage in ACE. - -Sat Feb 4 22:47:34 1995 Douglas C. Schmidt (schmidt@tango) - - * libsrc/Service_Configurator/Service_Object: changed the - destructor to be virtual (thanks to Steffen Winther Sorensen - <sts@dad.stibo.dk> for noticing this). - -Sat Jan 28 16:29:49 1995 Douglas C. Schmidt (schmidt@tango) - - * Changed the name of class Map_Manager's Search_Structure struct - to Map_Entry. This is more specific to what that data structure - really does. - - * Began adding support for Linux, courtesy of sts@dad.stibo.dk. - -Sun Jan 22 23:15:38 1995 Douglas C. Schmidt (schmidt@tango) - - * Changed the name of the ./libsrc/Connector-Acceptor directory to - ./libsrc/Connection. Also changed the name of libConn_Acc.so to - libConnection.so to be more consistent. - -Sat Jan 21 13:59:18 1995 Douglas C. Schmidt (schmidt@tango) - - * libsrc/IPC_SAP: Fixed the *Acceptor classes for SOCK_SAP and - SPIPE_SAP so they behave just like FIFO_SAP and contain a method - called remove(). This method closes the underlying descriptor - and also unlinks the local address from the file system. - - * libsrc/ASX/Message_Queue.i (copy): Fixed this code so that it - correctly stores starting at the wr_ptr rather than the rd_ptr. - Thanks to Chris Cleeland - (chris@milo.st-louis.mo.us) for pointing this out - to me. - -Wed Jan 11 13:07:19 1995 Douglas C. Schmidt (schmidt@tango) - - * Changed all uses of class Thr_Manager to class Thread_Manager - and class Thr_Cntl to Thread_Control. This is more readable and - is now consistent with the documentation... - -Tue Jan 10 13:49:31 1995 Douglas C. Schmidt (schmidt@tango) - - * Modified the makefile scheme so that only the *.so files are - built by default. If you want to build both *.a and *.so files, - uncomment out the lines described in - $WRAPPER_ROOT/include/makeinclude/rules.lib.GNU. Note that this - will require you to run make on the ./libsrc directories twice - in order to properly build and install both the *.a and *.so - libraries. - -Mon Jan 9 22:57:29 1995 Douglas C. Schmidt (schmidt@tango) - - * libsrc/Reactor/Signal.h: Changed the name of the Signal_Block - class to the Signal_Guard class to be more consistent with the - Guard class in Synch.h. - -Sat Jan 7 19:49:46 1995 Douglas C. Schmidt (schmidt@tango) - - * tests/ASX/Event_Server/Event_Server: Revised the Event Server - test example to use the Acceptor pattern components. - -Fri Jan 6 23:38:21 1995 Douglas C. Schmidt (schmidt@tango) - - * Added a new method to class Task that turns a task into an - active object (i.e., associates a thread of control with the - task). This is useful since it replaces all the places in - application code that original said "this->thr_mgr_.spawn - (THR_FUNC - (&this->svc_run))", etc... - -Thu Jan 5 21:05:15 1995 Douglas C. Schmidt (schmidt@tango) - - * libsrc/ASX: Changed the capitalization of class STREAM to class - Stream. This seems more reasonable since I don't see any - particular reason to shout about Streams! - - * libsrc/ASX/Task: Changed name of method qreply() to reply() to - reflect the fact that the name of the class is no longer Queue! - - * libsrc/ASX: Made both Task and Message_Queue into parameterized - types. This greatly improves the ability to parameterized - synchronization into an application. - - * Changed all occurrences of timestruc_t to use Time_Value - instead. This helps to improve portability and reduce the - "impedence mismatch" caused by mixing both C and C++ types in - the ACE interfaces. Note that one drawback of this is that we - lose nano-second timing accuracy. However, I don't know of any - real OS platforms that support that degree of precision anyway! - - * libsrc/Reactor: Moved the static "zero" data member from the - Timer_Queue class to the Time_Value class. Also added a new - static data member called "zerop," which is a pointer to "zero". - - * libsrc/Threads/Synch: Changed the interface of class Condition - so that it no longer has both wait() and a timedwait() methods. - Since C++ has default values, these two methods were redundant. - Now, there is only a single method called wait(). By default, - it's argument is 0, which defaults to the original wait() - semantics. If the argument is non-zero then the timewait - semantics apply. - - * libsrc/Threads/Synch: Added a new class called Null_Condition. - This is similar to the Null_Mutex class in the sense that it has - the same interface as class Condition, but it's methods are all - no-ops - (however, wait() and signal() both set errno = ETIME - before returning...). This class is useful for - parameterizing synchronization into an application. - |
