Schmidt (schmidt@tango) + + * libsrc/ASX: Changed the behavior of Map_Manager::Map_Manager() + to allocate a default-sized buffer. + + * libsrc/Reactor/Reactor.C (dispatch): Made the poll-based Reactor + smarter about detecting POLLERR error conditions. When POLLERR + is detected, the Reactor now shutdown down that fd... + +Wed Dec 21 18:29:15 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/IPC_SAP/SPIPE_SAP: Changed the name of class SPIPE_Msg to + SPIPE_IO to reflect the fact that I/O over named pipes need not + be message-oriented... + + * Changed all occurrences of {SOCK,TLI,SPIPE}_Listener to + {SOCK,TLI,SPIPE}_Acceptor. This is a more accurate name for the + function these classes perform. In addition, it is easier to + explain in the context of the Acceptor and Connector patterns. + Note that the *.h files are also changed, as well. + + * Changed the implementation of {SOCK,TLI,SPIPE}_SAP so that there + is now a *_Connector class to go along with the *_Acceptor + class. The *_Connector is a factory that produces *_Stream + objects *actively*, in a similar way to how the *_Acceptor is a + factory that produces *_Stream objects *passively*. This makes + everything much more orthogonal, though it will break existing + code... The easiest way to fix existing code is to do the + following: + + 1. Find places in the code that define objects of + type SOCK_Stream, LSOCK_Stream, TLI_Stream, + or SPIPE_Msg (now called SPIPE_IO). + + 2. Replace #include "SOCK_Stream.h" with + #include "SOCK_Connector.h" (or whatever + C++ wrapper you have). + + 3. Replace definitions of the form: + + INET_Addr addr (port, host); + SOCK_Stream foo (addr); + + with + + INET_Addr addr (port, host); + SOCK_Stream foo; + SOCK_Connector con (foo, addr); + + If you don't want to have an extra variable named "con", + you can replace this with: + + INET_Addr addr (port, host); + SOCK_Stream foo; + SOCK_Connector (foo, addr); // Calls the constructor. + +Tue Dec 20 21:34:10 1994 Douglas C. Schmidt (schmidt@tango) + + * Renamed the ./{libsrc,tests}/{Semaphores,Message_Queues} + directories to SV_Semaphores and SV_Message_Queues to better + reflect their true behavior and in order to prevent clashes with + the new ASX names. + + * libsrc/ASX: Renamed Queue to Task to better reflect its true + functionality. In addition, renamed Message_List to + Message_Queue. + +Mon Dec 19 23:04:52 1994 Douglas C. Schmidt (schmidt@tango) + + * Changed "private" to "protected" in ASX/Message_List.h at the + request of Troy Warner (tnw1@core01.osi.com). + +Mon Dec 12 23:47:01 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/IPC_SAP/SOCK_SAP: changed the name of the global utility + function "bind_port()" to ace_bind_port() to avoid polluting the + global symbol namespace. + + * Fixed a descriptor leak in SOCK_Dgram::shared_open() and + SOCK_CODgram::shared_open(). The original version didn't + automatically close down the socket descriptor if bind failed. + The new version does close the descriptor down. + +Sat Dec 10 00:53:20 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/Reactor/Reactor.C (mask_ops): Fixed a stupid bug... The + test should have been + + if (this->invalid_handle (handle) || + this->poll_handles_[handle].fd == -1) + + rather than: + + if (this->invalid_handle (handle) || + this->poll_handles_[handle].fd != -1) + + * libsrc/Reactor/Reactor: Modified the semantics of + Reactor::remove_handler() such that calling it with a value of + Event_Handler::DONT_CALL or'd into the Reactor_Mask instructs + the Reactor to remove the handler *without* calling the object's + handle_close() method! + +Fri Dec 9 12:53:31 1994 Douglas C. Schmidt (schmidt@tango) + + * include/Synch: some C++ compilers (e.g., Centerline) barf when + the see the following in an inline function: + + if (foo == bar) + { + errno = result; + return -1; + } + result result; + + I fixed this by doing the following: + + if (foo == bar) + { + errno = result; + result = -1; + } + result result; + +Wed Dec 7 22:23:47 1994 Douglas C. Schmidt (schmidt@tango) + + * include/Synch.h: Added additional methods in the Null_Mutex + class in order to be consistent with the RW_Mutex interfaces... + + * libsrc/ASX/Message_List: Added new a set of methods called + "try_enqueue_head" and "try_enqueue_tail" that will only insert + a message into the queue if it is not already full. If it is + full, return EWOULDBLOCK. + +Tue Dec 6 13:58:28 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/Reactor/Event_Handler: added default values of -1 to the + handle_input(), handle_output(), and handle_exception() methods. + +Mon Dec 5 23:30:28 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/ASX/Message_List: Added a new method called set_length to + Message_Block. This method sets the length of the "active" + portion of the message. This is defined as the offset from + RD_PTR to WR_PTR. + +Sat Dec 3 20:40:53 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/Threads/Synch: Added two new class called Write_Guard and + Read_Guard, which provide functionality a la the Guard class, + only that they acquire and release readers/writer locks. + + * libsrc/Threads/Synch: For interface uniformity with other + synchronization wrappers I added an acquire() method. This is + implemented as a write-lock to be on the safe-side... + +Fri Dec 2 13:33:39 1994 Douglas C. Schmidt (schmidt@tango) + + * include/Synch.i (Mutex::tryacquire): Modified the behavior of + Mutex::tryacquire so that it will return -1 and set errno to the + appropriate return value of tryacquire(3T) if various types of + "problems" occur (such as the Mutex already being held). + + * include/Message_List.i: Rearranged the order of the + Message_Block::get_rd_ptr and Message_Block::set_wr_ptr methods + to deal with inlining problems that some cfront-based C++ + compilers have... + + * libsrc/Reactor/Signal.[hi]: Changed set_handler/get_handler to + "handler" to avoid a collision with Rogue Wave libraries. This + new version is more consistent with other usage in ACE anyhow... + + * Modified the behavior of Service_Config::Service_Config() so + that it makes the initialize size of the Reactor be the same + size as the Service_Repository. This was done at the suggestion + of Bob Sayle and Steve Warwick at ARINC Research. + +Sun Nov 20 00:59:06 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/ASX/Message_List: Added two new methods + (is_full() and is_empty()) to the public interface + of Message_List. These methods check whether the queue is full + or empty *while holding the lock*. + + * libsrc/ASX/Queue.h: Made the svc() method a pure virtual + function. This is much cleaner than not doing it, particularly + when we've already got to define open(), close(), and put()... + + * Added a new method to the IPC_SAP/Addr inheritance hierarchy. + The method is called addr_to_string() and it converts the + address of a subclass (e.g., either UNIX domain or Internet + domain) into a string. This functionality is particularly + useful in parameterized types (such as Acceptor), which should + be oblivious of the type of communication domain they are + using... + + * Reorganized the ./apps/Logger/Service_Configurator_Logger + directory in order to reuse more code. Now, all the Acceptor + pattern classes have been moved to a new subdirectory called + ./libsrc/Acceptor. In addition, this code has been generalized + to work with the ASX framework! + +Sat Nov 19 15:19:19 1994 Douglas C. Schmidt (schmidt@tango) + + * Released version 2.15.5 (added a couple of minor fixes and some + additional software to the release. In particular, I've added + the RPC++ C++ wrappers for Sun RPC. See the README file for + more info on this. + + * apps/Synch-Benchmarks: Reorganized all the synchronization tests + so that they would be easier to understand and extend. + + * include/sysincludes.h (ACE_NONBLOCK): Fixed a stupid typo in the + ./include/makeinclude/wrapper_macros.GNU file that accidentally + used ACE_NONBLOCKING instead of ACE_NONBLOCK... Jaysus + + * Fixed up the Service_Config.[Chi] source so that it no longer + allocates statically linked services via static variables. + Stacy Mahlon (mcs@contour.mayo.edu) recommended this change to + workaround bugs in compilers that fail to initialize static + objects appropriately. + +Tue Nov 15 11:55:03 1994 Douglas C. Schmidt (schmidt@tango) + + * Fixed a portability problem in the ./libsrc/Service_Configurator + that was caused by certain compilers failing to initialize + global variables correctly. In particular, the Obstack object + ace_obstack is now a pointer that is allocated dynamically by + Service_Config.process_directive(). Thanks to Stacy Mahlon + (mcs@contour.mayo.edu) for noticing this! + +Mon Nov 14 12:16:14 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/Threads/Thread.h: added C++ wrappers for + thr_getconcurrency() and thr_setconcurrency(). + + * Fixed a dumb typo in ./tests/IPC_SAP/SOCK_SAP/CPP-nbclient.C + that failed to conditionally compile for different variants of + siginfo... + + * Added some test programs that benchmark the performance of + Solaris synchronization mechanisms. See ./apps/Synch-Benchmarks + for details... + + * Extended the methods of the Queue class to take advantage of the + new Message_List methods that perform timed waits! This + involves changing many of the existing methods in this class to + add an extra parameter of type timestruc_t *, which defaults to + 0. + + * Added some new comments in the + ./include/makeinclude/wrapper_macros.GNU file that indicate what + the various macros defined by the Makefile scheme actually mean. + This should help people who are porting to a new system... + + * Fixed a dumb bug in ./tests/Shared_Memory that directly included + system header files. Everything in ACE should include + "sysincludes.h" instead... Thanks to Stacy Mahlon + (mcs@contour.mayo.edu) for noticing this! + + * include/Memory_Pool.i (round_up): Fixed a typo where PAGESIZE + should have been ACE_PAGE_SIZE. + +Sat Nov 12 01:32:52 1994 Douglas C. Schmidt (schmidt@tango) + + * Generalized the Shared_Memory_Pool class for Malloc so that it + doesn't require the base addresses for multiple processes to all + start at the same location. + + * libsrc/Service_Configurator/Thread_Spawn.i (Thread_Spawn): + + Fixed a stupid bug in the constructor. Note that we should + be checking if this->tm_ == 0, rather than != 0... + +Fri Nov 11 00:11:41 1994 Douglas C. Schmidt (schmidt@tango) + + * Released version 2.15.4 (added a couple of minor fixes). + + * Added a new test program in the ./tests/ASX/Message_List + directory. This program illustrates how thread-safe + Message_Lists work using ASX. + + * libsrc/Threads/Thr_Manager.i: Added a new method called + insert_thr() to Thr_Manager that is used in conjunction with + Thr_Cntl::Thr_Cntl to make sure that a thread is added to the + Thr_Manager's table correctly. + +Thu Nov 10 20:14:11 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/Log_Msg/Log_Record.C (print): Fixed the following very + subtle (and very stupid) bug: + + return ::fprintf (fp, this->msg_data_); + + if this->msg_data_ contains '%', then this call will + fail since fprintf tries to treat the percent sign as + a format code. The obvious fix is: + + return ::fprintf (fp, "%s", this->msg_data_); + + * libsrc/ASX/Message_List.i (is_empty): Fixed a braino that failed + to check if there was a 0-sized buffer in the list. It is now + possible to enqueue a 0-sized buffer, which is helpful for + things like signaling end of transmission by a producer. + + * libsrc/ASX/Message_List.C: Improved the robustness of the + Message_List abstraction by detecting the case where the newly + inserted Message_Block is a NULL pointer. Before, this would + crash the program, where now it returns -1 from the + enqueue_head() or enqueue_tail() methods. + + * libsrc/Threads/Synch.h: added timedwait_signal() and timedwait() + methods to class Condition. These are wrappers around the + cond_t cond_timedwait() function. + + * Improved the documentation of the class interfaces in the + Synch.h C++ wrapper for Solaris 2.x threads mechanisms. + + * Changed the name of class Condition methods wait_signal() and + timedwait_signal() to wait_alert() and timedwait_alert() to + remove confusion with UNIX signals and the regular condition + variable signal. + +Wed Nov 9 23:49:24 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/IPC_SAP/Addr/UNIX_Addr.i (UNIX_Addr): Fixed another + couple brainos in UNIX_Addr.i (thanks for Irfan + (ip1@cs.wustl.edu) for noticing this). + + * libsrc/IPC_SAP/SOCK_SAP/SOCK.i (get_local_addr): Fixed a braino + that didn't reset the Addr size after a call to getsockname(). + +Tue Nov 8 00:25:02 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/Service_Configurator/Svc_Conf.y (create_service_type): + Fixed a bug on lines 323 and 324, and 330 and 331. The "#if + defined" needs to be INSIDE the "case" statements. Thanks to + mcs@contour.mayo.edu for finding this! + + * Improved the interfaces for all the synchronization wrappers so + that they can be given all the parameters for the underlying + SunOS 5.x *_init calls. Default values are given to keep the + normal usage concise... + +Mon Nov 7 21:41:13 1994 Douglas C. Schmidt (schmidt@tango) + + * Changed all occurrences of Mutex_Rec to Recursive_Lock. This is + much more descriptive since by using templates, the recursive + logic applies to a number of synchronization mechanisms (e.g., + Semaphores, RW_Mutex, Mutex, Null_Mutex, etc.) rather than just + the Mutex class. + + * Changed all occurrences of Mutex_Block to Guard. This is more + standard terminology and reflects Booch's terms more closely, as + well. + +Sun Nov 6 14:31:44 1994 Douglas C. Schmidt (schmidt@tango) + + * Majorly improved the modularity and structure of the Reactor + class. Much duplicate code has been coalesced and several new + features have been added. + + * Changed the name of the Reactor method set_ready() to + ready_ops(). Added a new method called mask_ops(). These + methods make it possible to manipulate the "dispatch masks" and + the "ready masks" (e.g., READ_MASK, WRITE_MASK, etc.) at a much + finer level of granularity without loss of efficiency or + correctness. + +Sat Nov 5 16:48:55 1994 Douglas C. Schmidt (schmidt@tango) + + * Changed the name of three methods in the Semaphore class to + mirror the terms used for Mutex and RW_Mutex. This will help + support the use of semaphores along with templates (e.g., + Rec_Lock) much better... The old names were "wait", "trywait", + and "signal". The new names are "acquire", "tryacquire", and + "release." + + * Added a new class called Signal_Block in Signal.[hiC] This class + operates similar to Mutex_Block, in that it holds a set of + signals over the duration of a C++ statement block. The + constructor masks out the signals and the destructor restores + the signals. + + * Changed the name of files Signal_Handler.[hiC] to Signal.[hiC] + to reflect a broadening of the functionality of the ACE wrappers + for Signals. For example, the new C++ classes wrap the sigset_t + API, as well as the struct sigaction structure. + +Fri Nov 4 00:41:48 1994 Douglas C. Schmidt (schmidt@tango) + + * Yow, got the new Shared_Malloc/Malloc class to work correctly on + SunOS 4.x, as well as SunOS 5.x. It's a bit more clunky on + SunOS 4.x since we have to use System V semaphores rather than + Solaris synchronization mechanisms. However, it now seems to + function correctly! + + * Added a new method called "tryacquire" to Semaphore_Complex and + Semaphore_Simple. This method provides the same "non-blocking" + semantics as it does in the Mutex, Semaphore, and RW_Mutex + classes. + + * Added a new method called "remove()" to all the C++ wrappers in + the Synch.[hi] file. This improves the symmetry with the System + V semaphore wrappers, and also gets around a nasty bug with + cfront 3.x and its handling of templates and explicitly called + destructors... + + * Added a new C++ wrapper class for Threads (Thread.h). The + eventual purpose of this class is to hide the differences + between POSIX pthreads and Solaris threads. + + * Added new parameters to Thr_Manager::spawn to enable the stack + and stack_size to be passed in. + + * Modified the Synch.h file so that the Null_Mutex and Mutex_Block + classes will both be compiled, even if we are building ACE on a + platform that doesn't support threads! + + * Added a timed event-loop method to the public interface of the + Service_Config class. This basically forwards the request to + the underlying Reactor->handle_events method. Thanks to Brad + Needham (bneedham@arinc.com) of ARINC research for the + suggestion! + +Wed Nov 2 14:47:25 1994 Douglas C. Schmidt (schmidt@tango) + + * Changed the interface for one of the Reactor's + {register,remove}_handler methods. These methods + had previously taken a sigset_t &, but for some reason the Sun + C++ 3.0 compiler can't seem to recognize that this is different + from an int! Therefore, I changed the interface to take a + sigset_t *. + + * Fixed some portability bugs that crept into the SunOS 4 version + of ACE, particularly with the siginfo_t extended signal handler + stuff. + +Tue Nov 1 21:46:07 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/Log_Msg/Log_Msg.C (log): Fixed a braino on line 175. + "int sig" was undefined outside the conditional (duhhh ;-)). + +Thu Oct 27 17:23:37 1994 Douglas C. Schmidt (schmidt@tango) + + * Fixed up some problems with Semaphore_Complex and + Semaphore_Simple. The new design should be more functional, + particularly for Semaphore_Complex, which now generalizes to + arrays of semaphores. + +Wed Oct 26 16:38:42 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/Shared_Malloc/: Created a .i file for Malloc and + Memory_Pool to handle inlines. + + * Fixed a fence-post error in Mem_Map::map_it(). The new version + should correctly set the length of the file *and* also do the + appropriate memory mapping. + + * bin/clone.C: Fixed the clone program so that it now compiles + with the C++ compiler rather than the C compiler. + +Tue Oct 11 20:01:16 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/Reactor/Reactor.h (Reactor): Changed the order of the + arguments to the Reactor's register_handler() method used to + register signal handler objects. The new order puts both "new" + components first, and any + (optional) old components following this. This is + a more natural set of default values... + + * libsrc/Shared_Malloc: split out the Local and Shared memory + pools for class Malloc into the Memory_Pool.[hC] files. + +Mon Oct 10 22:54:53 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/Threads/Synch.i: Reworked the Thread_Mutex and + Process_Mutex classes to inherit their interface and + implementation code from Mutex... Thanks to Irfan Payrali for + the suggestion! + +Wed Sep 28 11:26:34 1994 Douglas C. Schmidt (schmidt@tango) + + * Moved some of the tests directories around to better reflect + precisely which ACE components are being tested. In particular, + the {client,server} directories that were originally under the + ./tests/Reactor subtree are now located in the + ./tests/Service_Configurator subtree. + +Tue Sep 27 23:05:32 1994 Douglas C. Schmidt (schmidt@tango) + + * Added a bunch of constructors/destructors for + ./tests/Reactor/server to make g++ happy. + + * libsrc/Service_Configurator/Service_Object.[ih] + (Service_Object): Added a constructor and destructor to + Service_Object to make g++ happy. Also, removed the #if for + broken versions of g++ 2.5.8. + + * include/Reactor: Added a constructor and destructor for + Null_Callback to make G++ happy... + + * libsrc/Message_Queues/: Added support for G++ templates. + + * Changed the handling of _sys_siglist in the sysincludes.h file + to try and handle the weird SunOS 4 header file problems... + + * libsrc/IPC_SAP/SOCK_SAP/SOCK_Dgram_Brdcast.C (mk_broadcast): + Removed the "struct" from new struct ifnode in order to + compile... + +Tue Sep 20 11:17:23 1994 Douglas C. Schmidt (schmidt@tango) + + * Fixed a couple of minor typos in the Windows NT C++ wrappers for + sockets. + + * Released version 2.15.2 so that Mark Frutig could have access to + the latest source in order to write man pages! + +Thu Sep 15 20:47:36 1994 Douglas C. Schmidt (schmidt@tango) + + * Extended the Event_Handler interface to support the additional + siginfo_t-style parameters for extended SVR4 signal handling. + Note that for backwards compatibility, this new interface only + enabled if the -DACE_HAS_SIGINFO flag is set in the + wrapper_macros.GNU config file. Making this change affected + several of the existing ACE classes such as Service_Config and + Signal_Handler. + +Mon Sep 12 17:07:10 1994 Douglas C. Schmidt (schmidt@tango) + + * Improved the modularity of the Reactor by creating a new class + called Signal_Handler. This new class basically encapsulates + the signal handling mechanism provided by UNIX within a nice OO + abstraction. The new arrangement is particularly useful since + the Signal_Handler class may be used in applications + (e.g., the Malloc class abstraction) that do not require the + other features of the Reactor. + +Sun Sep 11 14:40:06 1994 Douglas C. Schmidt (schmidt@tango) + + * Changed the default value for Semaphore_Simple and + Semaphore_Complex from OPEN to CREATE. This is more closely + related to how SunOS thread synchronization variables work. + + * Changed the methods of the Semaphore_Simple class to be + syntactically equivalent to the Process_Mutex and Thread_Mutex + classes. This makes it easier to write code that uses + parameterized types to instantiate the appropriate type of + synchronization primitive. + + * include/makeinclude/rules.local.GNU (OBJDIRS): Fixed the + "depend" target so that it generates the correct dependencies + for remaking .so files after they are changed. + + * Added a new pair of methods to the Reactor so that it is now + possible to register/remove a sigset_t of signals in one + operation. + +Sat Sep 10 03:11:34 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/Mem_Map/Mem_Map.i (map_it): Fixed a few minor bugs with + how the Mem_Map::map() method handles lseek()'s. + + * Changed the name of the Mem_Map::open() methods to + Mem_Map::map(). This seems like a more reasonable name! Also, + removed the close() method. This is trivial to implement via + ::close (mmap.get_fd ()); + +Fri Sep 9 22:04:25 1994 Douglas C. Schmidt (schmidt@tango) + + * Provided a new implementation of a flexible memory allocation + scheme (Shared_Malloc/Malloc.[HiC]). This memory allocation can + be parameterized by the following: + + 1. The pool from which memory is allocated (e.g., + local memory vs. shared memory). + + 2. The type of synchronization used when allocating + the memory (e.g., no synchronization, thread-based + synchronization, process-based synchronization). + + * libsrc/Threads/Synch.i (Proc_Mutex): Added new classes to the + Synchronization library. These classes are wrappers around the + USYNC_PROCESS and USYNC_THREAD flags to mutex_init(). + +Wed Sep 7 20:29:00 1994 Douglas C. Schmidt (schmidt@tango) + + * include/sysincludes.h (MT): Added check to see if _REENTRANT was + already defined, and if so, avoid redefining it! + +Sun Sep 4 16:23:17 1994 Douglas C. Schmidt (schmidt@tango) + + * Released version 2.15.1 to the world... + + * Added support for the Windows NT version of SOCK_SAP. + + * Fixed a few minor bugs involved with the order of linking + libraries. + + * Fixed an oversight in ./testsReactor/server/server_test.C where + I was still including the "Server_Test.h" file (ugh). + +Wed Aug 31 13:27:10 1994 Douglas C. Schmidt (schmidt@tango) + + * libsrc/IPC_SAP/SOCK_SAP/SOCK_Stream.C (open): Fixed a bug + whereby the I/O descriptor wasn't being closed if connect() + failed. Thanks to Charles Eads + (eads@synoptics.com) for reporting this. + + + * Recompiled everything on SunOS 4.x using SunC++ 3.x and SunOS + 5.x using SunC++ 3.x and 4.x. Everything seems to compile fine + now. + + * Released version 2.15 + +Mon Aug 29 00:14:04 1994 Douglas C. Schmidt (schmidt@tango) + + * Finished up a preliminary set of tests for ASX. See the + $WRAPPER_ROOT/tests/ASX/Event_Server directory for more details. + + * wrapper_macros.GNU (CC): Removed the ARCHFLAG from the CCFLAGS + macro in the Makefile system. Henceforth, all conditional + compilation should be performed on a "per-feature" basis, rather + than a "per-platform" basis... + + * libsrc/IPC_SAP/SOCK_SAP/SOCK_Dgram_Brdcast.C (send): + Automatically convert the port number to htons format before + using it to initialize the sin_port field of the addressing + structure. This is consistent with the behavior of other parts + of IPC_SAP (particularly INET_Addr::set()). + +Sun Aug 28 00:02:53 1994 Douglas C. Schmidt (schmidt@tango) + + * Changed version number of 2.15 to reflect all the major + modifications to the structure of ACE. + + * include/sysincludes.h: Started to fix up the conditional + compilation scheme to be much smarter about the features that + are available from both the compiler and the OS environment. + + * Added a fix suggested by Leslee Xu (lxu@ics.uci.edu) to better + handle the normalization of Timer_Values. + + * Continued to make ACE coding conventions more consistent by + removing get_/set_ prefix from all the accessor/manipulator + methods. Also, added an underbar at the end of all class and + object instance variables. + +Sat Aug 27 20:28:13 1994 Douglas C. Schmidt (schmidt@tango) + + * Continued to improve error handling by replacing all uses of + perror with the Log_Msg macros. + + * include/sysincludes.h: Continued to improve the namespace + utilization in ACE by prefixing stand-along Misc functions with + ace_. + + * include/FD_Set.h: Changed the name FD_Set_Iter to + FD_Set_Iterator. + + * typedef'd int to HANDLE in Event_Handler.h in preparation for + merging in the Windows NT support along with the regular ACE + package. I need to update all the other code in the entire + release to be consist with this! + +Thu Aug 25 19:49:57 1994 Douglas C. Schmidt (schmidt@tango) + + * Fixed a bug with Thr_Manager.i that occurred if a thread created + by ::thr_create() exits prior to the acquisition of the lock and + the subsequent bookkeeping. + +Wed Aug 24 17:34:49 1994 Douglas C. Schmidt (schmidt@tango) + + * Updated SOCK_Dgram_Brdcast to return the average number of bytes + sent. This isn't necessarily the most useful info, but it + doesn't hurt either. Thanks to Mark Frutig (mfrutig@fnbc.com) + for the suggestion. + +Mon Aug 22 01:18:14 1994 Douglas C. Schmidt (schmidt@tango) + + * Added a new test for the Service Configurator framework. This + test illustrates the dynamic configuration of an entire stream + of Modules. + +Sun Aug 21 03:16:00 1994 Douglas C. Schmidt (schmidt@tango) + + * Cleaned up the ./tests/Reactor/server example to be more robust. + In particular, it doesn't really make sense to have the same + object be configured both statically and dynamically *at the + same time*! This was causing problems since each constructor + was getting called twice for the same object -- once when it was + created statically, and again when it was linked in + dynamically... Things work much better now. + +Sat Aug 20 01:07:24 1994 Douglas C. Schmidt (schmidt@tango) + + * Heavily revised the structure of the ./apps/Logger + subdirectories to test out the new Makefile scheme. Everything + is working fine on Solaris! + + * Updated all the ./apps/Logger subdirectories to use the Acceptor + name rather than the Client_Listener name. This is consistent + with recent papers... + + * Fixed all the Makefiles to utilize the new simplified build + strategy. The Makefiles are *far* more automated now! + + * Added support to all the libsrc Makefiles to produce both shared + libraries (*.so) and traditional archives + (*.a). + +Fri Aug 19 16:13:42 1994 Douglas C. Schmidt (schmidt@tango) + + * Majorly improved the Makefile support for building shared + objects that will be dynamically linked explicitly. No longer + will we have to do the horrible hack of compiling all the source + code using -pic. Instead, only that code that will be linked + dynamically must be compiled with -pic! Note that this only + works if the shared object is entirely self contained (i.e., it + does *not* reference any statically linked symbols that are not + defined in itself)! + + * Started to add changes to the source code to make its + configation driven by features rather than by OS. This should + make everything much more portable soon! + + * Fixed IPC_SAP.h so that the constructor is protected (prevents + accidental definition of an instance of this class). + +Thu Aug 11 08:31:33 1994 Douglas C. Schmidt (schmidt at valentine.ics.uci.edu) + + * Fixed Reactor::schedule_timer() so that it will unblock the + Reactor if it is currently blocked. This is necessary so that + the Reactor will recompute the amount of time that it needs to + wait before dispatching timer-based events. Thanks to Todd Hoff + for noticing this... + + * Fixed a stupid bug in the handle_input() method of + Client_Listener in both the Reactor and Service_Configurator + version of the Server Logging Daemon. This routine was not + explicitly returning 0 when it worked..., which might cause the + Reactor to deregister the listener handler! + + * Added casts to the ::select() call in the Reactor to ensure that + the FD_Set * -> fd_set * conversion operators are properly + involved. Thanks to Todd Hoff for this fix (thm@ictv.com). + Todd noticed that the DCE pthreads implementation on AIX was + confusing the compiler... + +Mon Aug 8 18:11:03 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Added a new constructor for the FD_Set class that will convert + an fd_set into an FD_Set. + + * Removed the default value for the Service_Repository constructor + since this was ambiguous with the default constructor. + +Tue Aug 2 18:25:28 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Fixed a bunch of minor "warning-causing" nits that were caused + by #endif __INLINE__ in certain header files... + + * Added a new set of interfaces to the Reactor to retrieve a + registered handler. These interfaces are also useful for + checking whether a handler is registered at a particular fd. + +Sun Jul 10 17:43:19 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Improved the implementation of the Profile_Timer and + High_Res_Timer classes. In particular, the High_Res_Timer class + now works quite nicely using SunC++ 4.0. + +Mon Jul 4 12:49:14 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Changed the order of the base class inheritance list for the + Service_Object class as a workaround for a bug in SunC++ 4.0's + handling of pointers to member functions (ugh). + +Sun Jul 3 18:07:16 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Added a bunch of changes (courtesy of + george@truffula.fp.trw.com). These changes fix minor + portability problems with the new SunC++ 4.0 compiler. + +Fri Jun 24 08:59:02 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Removed operator() from all the IPC_SAP listener classes. + Defining this operator was causing more trouble than it is worth + since C++ doesn't allow operator() to have default arguments + (ugh). The "right" thing to do is to simply use the accept() + method in those classes instead of operator(). + +Wed Jun 22 16:54:05 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Fixed some problems with TLI_Listener that involved lax scoping + of nested classes with cfront 3.x-based C++ compilers. + +Tue Jun 14 11:56:56 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Added a bunch of changes to get portions of ACE up and running + on SCO UNIX, on HP-UX, and on OSF/1. + +Tue Jun 7 14:32:50 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Added support for FLEX's <<EOF>> symbol to properly cleanup when + a configuration file has been parsed by the Service + Configurator's lexer/parser. + +Sun May 22 10:37:14 1994 Douglas C. Schmidt (schmidt at valentine.ics.uci.edu) + + * Modified the semantics of explicit dynamic linking on SunOS 4.x. + Now, if there is no _init or _fini function defined in a shared + library, it isn't an error (we simply don't call the function!). + +Mon May 9 07:58:35 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Included more fixes for GNU G++ courtesy of Aniruddha Gokhale + <gokhale@cs.wustl.edu>. + +Thu May 5 16:47:25 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Reimplemented the ./apps/Logger/Reactor_Logger to provide an + illustration of how the Reactor works. + + * Added finishing touches to the new version of the Service + Configurator framework. This framework now permits completely + automated configuration and reconfiguration of Service_Objects + and Streams. The next step is to add some more complete + examples that illustrate how these features are used... + +Tue May 3 10:17:12 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Fixed a bug in the Service Repository that would cause an + extraneous dlclose on a shared library handle under some + circumstances... + +Mon May 2 11:07:52 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Modified the semantics of Service_Object_Type in the Service + Configurator framework so that it does not automagically + register the service object with the instance of the Reactor. + The original behavior involved too much "over-specification" of + the behavior of Service Objects. Moreover, I can finally omit + the crazy semantics of DONT_REGISTER_SVC and REGISTER_SVC! + + * Fixed some subtle bugs involved with pop'ing a remove'ing a + Module from a Stream. Note that we need to use Module::link + rather than Module::set_next in order to ensure that all the + necessary pointers get rearranged.... + + * Fixed a couple of minor problems with deleting const objects in + the Service_Repository.i file. These were caught by G++, but + not caught by SunC++! + +Sun May 1 11:43:52 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Fixed subtle bug in Server_Config::run_event_loop(). This bug + prevented reconfiguration from occurring under certain + circumstances. + + * Added a new feature to the Service_Manager class in the Service + Configurator framework. This new feature enables the Service + Configurator to be reconfigured remotely by clients. + + * Fixed a bug in Service_Manager that caused the Service + Configurator to crash if SIGPIPE occurred if a client closed + down ungracefully while retrieving information on active + services. + + * Added a new argument to the Reactor::register_handler() method + that is used to register signal handling Event_Handlers. This + new argument returns the current Event_Handler (if any) that is + registered for this signal. + + * Fixed a potential bug in Service_Config::process_directives that + behaved improperly when there was no svc.conf file present in a + directory. + +Wed Apr 27 12:55:46 1994 Douglas C. Schmidt (schmidt at mabillon.ics.uci.edu) + + * Changed the name of Service_Directory to Service_Manager to + reflect its intended functionality + +Mon Apr 25 10:53:01 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Updated the Service Configurator framework to use the new signal + handling facilities provided by the Reactor. This cleans up a + lot of the code in Service_Config.i and removes the need for + ugly non-reentrant static class variables. + + * Released version 2.14 + +Sat Apr 23 14:29:11 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Changed the representation of the select()-based Reactor to be + more similar with the poll()-based Reactor. In particular, + there is only one array of Event_Handlers rather than three... + +Sun Mar 13 16:49:59 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Fixed a bug with the select-based version of the Reactor. This + bug caused problems when dispatching the handle_output() member + function. + + * Fixed a bug with the select-based version of the Reactor. This + bug resulted in a failure to call the handle_close() member + function on the write_fds and except_fds. + + * Changed the interface for Event_Handler::handle_close() so that + the second parameter is a Reactor_Mask. This allows the + call-back routine to determine which side of a connection (i.e., + read-side vs. write-side or both) to close down. Be careful + since this change may break existing code that used the original + 1 argument handle_close() member function. + + * Changed the location of the Reactor_Mask. It was originally an + enum in Reactor.h. It is now a typedef in Event_Handler. This + change will break existing code but it easily spotted since the + compiler will give an error! + +Sat Mar 12 15:16:59 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Continued to modify the grammar of the svc.conf file language. + The latest version (illustrated in configuration files in the + ./tests/Reactor/server and + ./apps/Logger/Service_Configurator_Logger file) is both easier + to read and to parse automatically. + +Tue Mar 8 10:19:40 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Changed the behavior of the Get_Opt class so that it will + perform option processing starting from argv[0] rather than + argv[1] if the SKIP argument to the constructor is set to 0. + Note that the default value is 1, so the behavior is the same + for backwards compatibility. Incidentally, this new change is + necessary to support the Service Configurator stuff... + + * Changed the names of some of the Service_Record member functions + to conform to the new idiom for naming get/set-style of member + function accessors... + +Sun Mar 6 12:47:03 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Removed libGet_Opt.a and merged it in with libMisc.a + +Sat Mar 5 18:37:43 1994 Douglas C. Schmidt (schmidt at tango.ics.uci.edu) + + * Updated the Service_Config class to use a flex/yacc based parser + rather than an ad hoc parser and lexer. This is useful since + the new syntax for configuring a complete Stream into a Service + Configurator-based application is more complicated... + + * Made a small change to the syntax of a svc.conf file. Now any + parameters that are passed to the Service_Object::init() member + function of a dynamically linked service must be enclosed inside + of double quotes. In other words, service config entries such + as + + dynamic ./dev_adapter.so:_alloc () Device_Adapter -p 3000 + + now become + + dynamic ./dev_adapter.so:_alloc () Device_Adapter "-p 3000" + + This change makes it easier to parse the input using flex/yacc. + +Sat Feb 12 18:53:14 1994 Douglas C. Schmidt (schmidt@net4.ics.uci.edu) + + * Modified the Reactor so that it now also demultiplexes signals, + as well as timer events and I/O events. This required making a + few sections of the Reactor code signal-safe, as well as + thread-safe. + + * Changing the Reactor to handle signals also required a slight + change to its interface. For example, it is now mandatory to + give the Event_Handler::{READ_MASK,WRITE_MASK,EXCEPT_MASK} when + registering a handler... + +Sat Feb 5 12:10:53 1994 Douglas C. Schmidt (schmidt@net4.ics.uci.edu) + + * Changed the Condition and Monitor classes to use templates that + parameterize them with the appropriate type of Mutex (i.e., + either Mutex or Mutex_Rec). This greatly cleans up the code... + Made a number of changes in other files + (such as the Reactor) to account for the changes. + + * Added a new class called Mutex_Rec which implements a recursive + Mutex abstraction on SunOS 5.x. Recursive Mutexes may be + acquired multiple times from a single thread. Basically, this + supports an efficient and clean way of handling nested locking + conditions. + +Thu Feb 3 12:37:34 1994 Douglas C. Schmidt (schmidt@net4.ics.uci.edu) + + * Fixed a bug in Service_Config.i that was causing SIGHUP-driven + reconfiguration not to work correctly. + + * Added a set of new member functions to the Reactor class to + suspend() and resume() an event handler. Also added suspend() + and resume() member functions to the Server_Object class to take + advantage of these new facilities automagically... + +Mon Jan 31 09:47:06 1994 Douglas C. Schmidt (schmidt@net4.ics.uci.edu) + + * Modified the no-args constructor for the Reactor to initialize + it to the DEFAULT_SIZE. The prior behavior was *not* to + initialize it at all, which seems rather dumb in retrospect... + + * Improved the Reactor's support for multi-threading by adding a + pipe() call that is used to force the Reactor to reconfigure + itself everytime a new handler is registered or removed. + Previously, any new changes wouldn't take place until the + Reactor was triggered by some external event. This old behavior + was too non-deterministic... + +Sun Jan 2 12:35:39 1994 Douglas C. Schmidt (schmidt@net4.ics.uci.edu) + + * Modified the inheritance hierarchy for Service_Object so that it + derives from both Shared_Object and Event_Handler. + Shared_Object is a new abstract base class the provides an + interface for dynamic linking of objects. When RTTI is widely + available for C++ the Service Configurator will be much more + functional since we can automatically figure out whether an + object is a Service_Object or just a Shared_Object and do the + right thing with it! + |
