Thanks to Marina Spivak + <marina@cs.wustl.edu> for reporting this. + +Tue Jul 01 14:47:22 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/High_Res_Timer.{h,i} (gettime): use gettime () static function + to wrap all calls to ACE_OS::gethrtime ().

Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/Connector.cpp (create_AST): Replaced the gratuitous #ifdef + for ACE_WIN32 and EXCEPT_MASK with the new CONNECT_MASK. This + is much cleaner! + + * ace/Event_Handler.h: Added a new CONNECT_MASK that defaults to + READ_MASK | WRITE_MASK (with | EXCEPT_MASK thrown in for Win32). + Thanks to Irfan for this suggestion. + +Thu Jun 26 19:53:11 1997 Nanbor Wang <nw1@lambada.cs.wustl.edu> + + * ace/OS.i (strtok_r): Added check on a null string so we won't go + past the end of a string. + + * performance-tests/Misc/context_switch_time.cpp (main): Added + get_env_gloval_scale_factor() at the very beginning so that high + resolution timer can return correct time in millisecond. + +Thu Jun 26 15:29:55 1997 Darrell Brunsch <brunsch@cs.wustl.edu> + + * tests/Timer_Queue_Test.cpp: Changed the random scheduling to use + past times instead of future time. This should fix some unusual + behavior of this test. Thanks to Gonzalo A. Diethelm + <gonzo@ing.puc.cl> for reporting this. + +Thu Jun 26 12:38:16 1997 Douglas C. Schmidt <schmidt@cs.wustl.edu> + + * ACE version 4.2.12, released Thu Jun 26 12:38:16 1997. + +Thu Jun 26 01:11:10 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/Svc_Conf.y: Added some sanity checks to make sure we don't + segfault when things go wrong during the svc.conf file parsing. + Thanks to Steve Huston for this suggestion. + +Thu Jun 26 08:36:37 1997 David L. Levine <levine@cs.wustl.edu> + + * Makefile: fix UPTODATE check (for release target) by not + running it in a sub-shell. Also, added ACE-lessons.html + to RELEASE_FILES. + + * performance-tests/Misc/context_switch_time.cpp: use same priority + values on Win32 platforms as on Solaris, because thread priority + increases with increasing priority values on both of those platforms. + +Thu Jun 26 01:34:46 1997 Nanbor Wang <nw1@lambada.cs.wustl.edu> + + * performance-tests/Misc/misc.{mak,mdp}: Added makefile for NT. + + * ace/{FILE,DEV}.{h,i}: Added the disable(int signum) function to + prevent NT from disabling a FILE/DEV using socket calls. + +Wed Jun 25 12:59:00 1997 <irfan@TWOSTEP> + + * ace/Synch_T.h (ACE_SYNCH_PROCESS_MUTEX and + ACE_SYNCH_NULL_MUTEX): Added new template typedef to the list. + + * tests/Message_Queue_Notifications_Test.cpp: New test for + demonstrating notification qualities of Message_Queue. + + * ace/Strategies.h: Added accessors to these classes to make them + more usable. + +Wed Jun 25 10:47:34 1997 Steve Huston <shuston@riverace.com> + + * ace/Parse_Node.cpp: Insure that ACE_Object_Node::symbol(void) + returns 0 if the underlying shared library can't be loaded. + + * ace/OS.h: Added a new type, ACE_SHLIB_HANDLE to allow dynamic + linking using correct types on all platforms that support it. + Also added a const ACE_SHLIB_DEFAULT_MODE for the 'mode' argument + when doing a dlopen-like operation. + Moved the ACE_OSCALL_* macros to this file from OS.i + + * ace/OS.i: Moved ACE_OSCALL_* macros out of here and into OS.h. + Added support for dlopen/close/sym/error on HP-UX. Note - the + Service_Configurator tests do not run yet on HP - I'm working on + that. + + * ace/Service_Record.{h, i, cpp}: Use new ACE_SHLIB_HANDLE type for + dynamic loading operations. + + * ace/Parse_Node.{h, cpp}: Use new ACE_SHLIB_HANDLE where appropriate. + + * ace/Strategies_T.cpp: Use new ACE_SHLIB_HANDLE type. + +Wed Jun 25 02:36:05 1997 Nanbor Wang <nw1@lambada.cs.wustl.edu> + + * ace/OS.i (gmtime_r): Modified the implementation of gmtime_r + when OS doesn't provide one. Notice that the implementation + only simulate the semantic and is not thread-safe. + + * ace/OS.h: Moved definition of ACE_SHLIB_HANDLE typedef and + ACE_DEFAULT_SHLIB_MODE global variable for Win32 to where it + belongs. + + * ace/OS.i: Changed the return type of dlopen() when ACE_HAS_UNICODE to + ACE_SHLIB_HANDLE. + + * ace/OS.{h,i}: Moved ACE_OSCALL and ACE_OSCALL_RETURN for WIN32 + from OS.i to OS.h. + +Wed Jun 25 01:23:58 1997 Nanbor Wang <nw1@dingo.wolfpack.cs.wustl.edu> + + * ace/OS.i (strtok_r): Modified the implementation when OS does + not provide reentrant strtok_r so that our imp. comforms with + the semantic of strtok_r (). + +Wed Jun 25 00:37:56 1997 Douglas C. Schmidt <schmidt@cs.wustl.edu> + + * ACE version 4.2.11, released Wed Jun 25 00:37:56 1997. + +Tue Jun 24 21:30:53 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/Svc_Conf_y.cpp: commented out unused args and wrapped + assignments in "if" conditionals with parenthesis to avoid + g++ warnings. + +Tue Jun 24 18:15:46 1997 Nanbor Wang <nw1@dingo.wolfpack.cs.wustl.edu> + + * ace/Reactor.cpp (wait_for_multiple_events): Modified the way to + manipulate timeout value so that we can differentiate when there + are timeout events to be handle from no timer and we want to + wait indefinitely. + +Tue Jun 24 16:52:22 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/OS.h: reverted ACE_hrtime_t to unsigned __int64 with VC++. + This might break something, but we need to know what. + +Tue Jun 24 16:38:52 1997 Darrell Brunsch <brunsch@cs.wustl.edu> + + * Added Visual C++ 5.0 specific workspace (.dsw) and project (.dsp) + files to both the ace and tests subdirectory. ACE.DSW in the root + directory contains all the project files, so a batch build should + be able to build all the project files. + +Tue Jun 24 14:27:47 1997 Darrell Brunsch <brunsch@cs.wustl.edu> + + * ace/Timer_{Hash,Heap,List,Wheel}_T.cpp: Changed cancel (type..) + to call cancellation() even if there are no timers to cancel. + This causes the correct behavior of calling handle_close () + during expire when handle_timeout() returns -1. Thanks to + Hamutal Yanay <hamutal_yanay_at_quantum@mail.icomverse.com> for + pointing this out. + + * tests/Timer_Queue_Test.cpp: Updated to correctly test this. + +Tue Jun 24 13:02:51 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/SString.h (ACE_SString ctor): changed "allocator" to "alloc". + Thanks to Brian Mendel <bmendel@mdc.com> for reporting this. + +Tue Jun 24 12:58:28 1997 James C Hu <jxh@lambada.cs.wustl.edu> + + * include/makeinclude/platform_irix6.4*: Shuts up useless warnings + about multiply defined template instances. + +Tue Jun 24 12:50:52 1997 Douglas C. Schmidt <schmidt@cs.wustl.edu> + + * ACE version 4.2.10, released Tue Jun 24 12:50:52 1997. + +Tue Jun 24 00:44:30 1997 Nanbor Wang <nw1@lambada.cs.wustl.edu> + + * ace/SPIPE.{h,i}: Added the disable(int signum) function to + prevent NT from disabling an SPIPE using socket calls. + +Mon Jun 23 22:14:39 1997 Douglas C.

Levine <levine@cs.wustl.edu> + + * ace/ACE.cpp: added auto_basic_array_ptr specialization. + + * ace/Service_Config.cpp, tests/Future_Test.cpp, + examples/Threads/future[12].cpp: added auto_basic_ptr + specializations. + + * include/makeinclude/platform_vxworks5.2_g++.GNU: + reworked to supported different targets, instead of only PowerPC. + +Mon Jun 23 16:06:35 1997 James C. Hu <jxh@swarm.cs.wustl.edu> + + * ace/OS.i: Moved definition of sema_* methods to follow cond_* + methods to remove compiler warnings on SGI. + +Mon Jun 23 09:42:08 1997 Darrell Brunsch <brunsch@cs.wustl.edu> + + * tests/Timer_Queue_Test.cpp: added testing for cancellation + during expire (when of handle_timeout() in an event handler + returning -1). + +Mon Jun 23 09:18:39 1997 David L. Levine <levine@cs.wustl.edu> + + * Makefile: added up-to-date check for "make release" from + /project/adaptive/ACE_wrappers. Also, "make release" now + adds release entry to latest ChangeLog. + + * ace/Makefile: build shared library before static library. + This appears to fix a problem with Sun C++ 4.{1,2} possibly + related to its template instantiation scheme. If the + static library is built first, then .shobj/Reactor.so + and .shobj/Timer_Hash.so (and possibly others) fail to + build due to ACE_TimeValue::normalize () "relocations remain + against allocatable but non-writable sections". + Thanks to Steve Huston <shuston@riverace.com> and + Satoshi Ueno <satoshi.ueno@gs.com> for reporting this, and + to Satoshi for verifying the fix. + + * ace/ACE.cpp (terminate_process): removed used of + ACE_OSCALL_RETURN macro because its defined in OS.i, and so + not available if inlining is disabled. + + * ace/Auto_Ptr.{h,i}: made "p_" protected instead of private + so that it can be accessed with the new class arrangement. + Also, made the auto_array_ptr operator-> const. + + * ace/Sched_Params.cpp (previous_priority, VxWorks only): + removed ACE_UNUSED_ARG (policy) because policy is used in + this function. + + * netsvcs/lib/TS_Clerk_Handler.cpp (parse_args): wrapped TCHAR + argument to sizeof in parenthesis. + +Mon Jun 23 09:12:04 1997 Nanbor Wang <nw1@lambada.cs.wustl.edu> + + * ace/Auto_Ptr.i (auto_array_ptr): Fixed a typo. + +Mon Jun 23 08:03:46 1997 Darrell Brunsch <brunsch@cs.wustl.edu> + + * ace/Auto_Ptr.h: changed inheritance of auto_basic_array_ptr in + auto_array_ptr to include the template parameter X. + + * ace/IOStream_T.i: removed default parameter in the definition + of ACE_Streambut_T::recv_n() and ACE_SOCK_Dgram_SC::recv_n() + +Mon Jun 23 01:13:15 1997 <irfan@TWOSTEP> + + * ace/OS.cpp (fork_exec): Fixed the usage of ACE_WIDE_STRING. + + * test_registry_iterator.cpp (main): Fixed the usage of + ACE_WIDE_STRING. + + * netsvcs/lib/TS_Clerk_Handler.cpp (parse_args): Fixed the usage + of ACE_WIDE_STRING. + + * ace/Auto_Ptr.h: Added support for basic types by seperating the + auto_ptr classes into two. One that requires the -> operator + support and the other that does not. The former inherits from + the latter. + + * ace/{FILE,DEV,SPIPE}_Addr.h: Added support for multibyte and + wide character addr_to_string and string_to_addr functionality. + + * ace/Connector.cpp && ace/Acceptor.cpp (info): Fixed sizeof bug. + + * examples/Connection/blocking/SPIPE: Added UNICODE support for + this example. + + * ace/OS.h: Added new macro ACE_MULTIBYTE_STRING. + + * ace/ACE.cpp (terminate_process): Fixed unused args errors. + +Sun Jun 22 09:58:36 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * Released version 4.2.9 for testing. + + * ace/Log_Msg.cpp (open): Changed the use of ACE_LOG_MSG-> within + the open() method to use this-> in order to avoid deadlocks. + Thanks to Per Andersson for reporting this. + + * ace/ACE.cpp: Changed the use of __SVR4 and __unix to sparc and + unix to work better with various UNIX environments. Thanks to + Michael R. MacFaden <mrm@cisco.com> for these changes. + + * ace/Handle_Set.cpp (count_bits): Added special code to handle + the case where fdmask is typedef'd as a long rather than an int. + Thanks to Eric Newton <ecn@smart.net> and James Johnson for + reporting this. + + * ace/IOStream.h: Changed the name of QuotedString to + ACE_Quoted_String to be consistent with the ACE naming scheme. + Thanks to James Johnson for suggesting this. + + * ace/IOStream_T.i: Added this new file to split off the inlined + code from the header file. + + * ace/ACE.cpp (terminate_process): Remove the + ACE_UNUSED_ARG(signum) from terminate_process(). Thanks to Wei + Chiang for reporting this. + +Sun Jun 22 17:19:18 1997 David L. Levine <levine@cs.wustl.edu> + + * examples/Threads/process_manager.cpp (main): replaced call to + kill with terminate. + +Sat Jun 21 10:48:34 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * examples/Reactor/FIFO: Added a new example that illustrates + how the Reactor and the FIFO wrappers work together. Thanks + to Johannes Gutleber <Johannes.Gutleber@cern.ch> for sending + this. + + * tests/Time_Service_Test.cpp (main): Replaced the kill() call + with the terminate() call since kill() isn't portable across + platforms. + + * ace/Process: The kill() method on this class was being used + incorrectly. I've created a new method called terminate() that + terminates the process. + + * ace/Process_Manager: Renamed the kill() method to terminate() + and updated the implementation to use the new + ACE::terminate_process() call. + + * ace/ACE: Moved the incorrect Win32 and Chorus implementations of + ACE_OS::kill() and put them in a new static method called + ACE::terminate_process(). + + * ace/ACE: Changed the name of the is_process_active() to the + more concise process_active(). + + * ace/OS.i: Added an implementation of ACE_OS::kill() for Chorus. + Note that this doesn't behave as UNIX does -- it kills the + process id rather than sending a signal! Thanks to Wei Chiang + <chiang@tele.nokia.fi> for these fixes. + + * examples/Reactor/Misc/notification.cpp: Added patches to run + this example under Chorus. Thanks to Wei Chiang + <chiang@tele.nokia.fi> for these fixes. + + * ace/Connector.cpp (create_AST): Changed the order of some + instructions in Connector::create_AST method to make it more + safer to use in multi-thread environment. Thank to Paul Han + <phan@CCGATE.HAC.COM> for reporting the problem and the fix. + + * ace/Connector.cpp (create_AST): Make sure to pass in the "mask" + when calling remove_handler() so that we get the right set of + bits removed from the Reactor. + + * tests/Reactor_Timer_Test.cpp (class Time_Handler): Changed int + to long to avoid type conversion problems on 64 bit SGI. Thanks + to Fred LaBar <flabar@fallschurch.esys.com> for reporting this. + + * examples/Reactor/FIFO: Added a test program to illustrate the + interaction of the ACE Reactor with the FIFO IPC mechanism. + Thanks to Johannes Gutleber <Johannes.Gutleber@cern.ch> for this + test. + + * examples/Reactor/Misc/pingpong.cpp: Added support for Chorus. + Thanks to Wei Chiang <chiang@tele.nokia.fi> for this. + + * ace: Added a number of minor changes to signal assignment + code so that ACE will compile with Tandem NonStop. Thanks + to Jan Perman <uabjjpp@osd.ericsson.se> for these fixes. + + * ace/config-tandem.h: Added a new config file for the + Tandem NonStop-UX 4.2MP platform. Thanks to Jan Perman + <uabjjpp@osd.ericsson.se> for contributing this. + + * include/makeinclude/platform_tandem.GNU: Added a new platform + file for the Tandem NonStop-UX 4.2MP platform. Thanks to + Jan Perman <uabjjpp@osd.ericsson.se> for contributing this. + + * ace/config-unixware-2.1.2-g++.h: Added a new config file for + UNIXWARE 2.1.2. Thanks to Ganesh Pai (gpai@voicetek.com) for + contributing this. + + * include/makeinclude/platform_unixware_g++.GNU: Updated the + UNIXWARE platform config file to work for version 2.1.2. Thanks + to Ganesh Pai (gpai@voicetek.com) for contributing this. + + * ace/Handle_Set.cpp (count_bits): Added another 0xff mask to + prevent problems with sign extension on machines with 32 bit + ints and 64 bit longs. Thanks to James Johnson for reporting + this. + + * ace/OS.h: Updated all of the ACE_DEFAULT* macros in OS.h so that + they can be overridden by #defines in the config.h file.

Levine <levine@cs.wustl.edu> + + * ace/config-sunos5.5-sunc++-4.x.h, + include/makeinclude/platform_sunos5_sunc++.GNU: support enabling of + exception handling via "exceptions=1" make flag. Exception handling + does seem to work with Sun C++ 4.2, even on MP machines, if patch + 104631-02 "C++ 4.2: Jumbo Patch for C++ 4.2 on Solaris SPARC" + is applied. Please beware that enabling of exception handling can + adversely affect peformance, even if the program doesn't use it. + So, we haven't enabled it by default. Thanks to Chris Cleeland + for suggesting not to enable it by default. + + * ace/IOStream.h: added #include of "ace/config.h" so that + ACE_LACKS_ACE_IOSTREAM can be checked. Thanks to Ganesh Pai + <gpai@voicetek.com> for reporting this problem. + + * ace/ACE.cpp (get_handle): use /dev/udp instead of /dev/ip on + SVR4 machines because it has other read permission by default + (on Solaris 2.x). + + * ace/ACE.cpp (get_ip_interfaces): use auto_array_ptr instead of + auto_ptr so that the array gets deleted properly, and zero it + out to avoid unitialized memory read reports from Purify. + + * ace/Timer_Hash_T.cpp (cancel): added "[]" to delete of timer_ids + array.

Reassigning the linked library + solved the problem. + + * examples/OS/Process/process.cpp: Updated class name + ACE_ProcessEX to ACE_Process because ACE_ProcessEX no longer + exists. Also, all exec'ed programs' absolute names have been + changed and let the environment variable "path" to decide which + program(s) to exec. + +Thu Jun 12 15:48:16 1997 Chris Cleeland <cleeland@cs.wustl.edu> + + * ace/ACE.cpp (get_ip_interfaces): Corrected code in the BSDish + section so that it at least compiles on Linux. I haven't tested + this AT ALL. + + * ace/Timer_Queue_T.cpp (calculate_timeout): When this was called + with the default argument from handle_events(), max_timeout was + passed as zero, which would cause a SEGV when attempts were made + to deref it. Added protection to simply return a zero ptr in that + case. + +Thu Jun 12 13:18:03 1997 Steve Huston <shuston@riverace.com> + + * ace/OS.{h,i,cpp}: Changes for HP-UX 10 primarily. Threads + support for DCE Draft 4 threads (bundled with HP-UX 10). + Correct usage of reentrant C library functions for HP-UX. + + * ace/OS.i: Changed timeout argument to 2nd select function to + allow the compiler to pick a conversion operator. As it was, + HP compiler would not compile it. + + * ace/Service_Object.cpp: When deleting the service memory pointed + to by a void *, use "operator delete" rather than deleting a void, + which is prohibited by the current ANSI C++ draft. + + * ace/config-hpux-10.x.h: This is now a compiler-independent header + file, and is included by config-hpux-10.x-hpc++.h. This file + contains all correct settings for HP-UX 10.x, and compiler-specific + config files should use this - see config-hpux-10.x-hpc++.h. + + * ace/config-hpux-10.x-hpc++.h: New config file for either of the HP + compilers (HP C++ or HP aC++). It figures it out internally, and + uses config-hpux-10.x.h for OS details. + + * include/makeinclude/rules.lib.GNU: Allow for doing a PRELIB step + when building a shared library, and not using .shobj/*.so files. + This allows HP aC++ to close all template instantiations for the + entire library at once, rather than separately, reducing the + size of the resultant library significantly. + + * include/makeinclude/platform_hpux-aCC.GNU: build libraries with + templates instantiated all at once.

Since the pointer itself is + not modified within the function, it's ok to change this. + + * ace/Reactor.cpp (wait_for_multiple_events): Added ACE_Time_Value + the_timeout as a place holder for timeout value when + max_wait_time is NULL. Otherwise, + Timer_Queue::calculate_timeout won't process the timer queue + even it's not empty. + +Wed Jun 11 11:14:29 1997 James C Hu <jxh@lambada.cs.wustl.edu> + + * include/makeinclude/platform_mvs.GNU (RANLIB): Requested change + from Check Gehr (gehr@sweng.stortek.com), RANLIB = echo + +Wed Jun 11 04:47:52 1997 Nanbor Wang <nw1@dingo.wolfpack.cs.wustl.edu> + + * ACE.cpp (count_interfaces): Two bugs were corrected here.

I have added a new + mutex_lock() method that takes an extra "abandoned" parameter. + This is set wehen the mutex is abandoned. Thanks to Dieter + Quehl <dietrich.quehl@med.siemens.de> for pointing this out. + +Mon Jun 9 02:31:36 1997 Nanbor Wang <nw1@siesta.cs.wustl.edu> + + * tests/Sigset_Ops_Test.cpp (main): Comment out testing of invalid + sigset checking for most platforms don't seem to support it. + Perhaps the ACE's sigset* functions should remove this check for + compatibility. + +Sun Jun 8 11:39:06 1997 Douglas C.

Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/SString.h (string.): Added a substring() member function to + ACE_*String classes. Thanks to Michael MacFaden <mrm@cisco.com> + for contributing this. + + * ace/ACE: Added a new method called + + int get_ip_interfaces(count, address_array) + + which will query the OS kernel for the IP addresses for each network + interface found and return a count and array of ACE_INET_Addr objects. + The reason for adding this method is that most client apps + assume gethostbyname(uname|gethostname)) will work. If the + nameservices is misconfigured/broken or the machine is multi-homed, + the client apps have alot of coding to do to figure out if an inteface + represents a local address or not. On UNIX, this includes + the loopback addr. On NT, the loopback addr is not added + (but may change the impl if others think this useful). + Thanks to Michael MacFaden <mrm@cisco.com> for contributing + this. + + * ace/Synch[_T]: Changed all the classes so that internal instance + variables are now protected rather than private. This allows + greater flexibility if there's a need to subclass + (which shouldn't occur very much...). Thanks to + Reza Roodsari <reza@sprynet.com> for suggesting this. + +Fri Jun 06 21:30:57 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/Timer_{Hash,Wheel}_T.cpp: added #includes of + ace/High_Res_Timer.h.

Thanks to John Morey + (jmorey@tbi.com) for the changes. + +Fri Jun 06 02:16:08 1997 <nw1@COYOTE> + + * Sigset_Ops_Test.cpp: Added to test correct implementation of + sigset manipulating functions. + + * run_tests.{sh,bat}, Makefile: Added Sigset_Ops_Test. + +Thu Jun 05 20:32:39 1997 David L. Levine <levine@cs.wustl.edu> + + * tests/Timer_Queue_Test.cpp (randomize_array): removed static + qualifier now that it's a template function.

This has a small + performance win over the other b/c it does not take a lock. + The change was made after examining Quantify output for TAO + and observing that this lock caused + Reactor::wait_for_multiple_events() to consume a substantial + percentage of processing time. + + * ace/Reactor.cpp (wait_for_multiple_events): This now uses a + different version of calculate_timeout() that doesn't require + taking a lock. + +Thu Jun 05 08:48:49 1997 David L.

ACE_Timer_Hash is typedefed to the Timer List + version and ACE_Timer_Hash_Heap is typedefed to the Timer Heap + version + + Added HighRes timer support + + Added upcall functor deletion() support + + Created an expire that is specialized for ACE_Timer_Hash + + Added remove_first () method that removes and returns the + earliest timer in the queue + + Added check for timer_id of -1 so we don't try to delete the + error code if it is passed into cancel + + * ace/Free_List.* + + Added ACE_Free_List<T> and ACE_Locked_Free_List<T, LOCK>.

Added new -woff flags to hide + other warnings. + + * ace/config-irix6.4-sgic++*.h: copied corresponding configs from + irix6.2 and removed ACE_HAS_SVR4_TIME, since this seems to be no + longer true of irix6.4. + +Fri May 30 02:39:39 1997 <irfan@TWOSTEP> + + * ace/Connector.cpp + + (create_AST): On Win32, added the except mask when registering + with the Reactor to find out when asynchronous connects + complete. + + (Svc_Tuple): Made sure that the default value for the timer_id + in AST is not 0. 0 is a valid timer_id. I have changed this to + be -1. + + (handle_exception): Added this method. On + Win32, the except mask must also be set for asynchronous + connects. + +Thu May 29 21:28:25 1997 <harrison@samba.cs.wustl.edu> + + * Process.*: Removed the ACE_Process_Old class. + + * Local_Tokens_T.*: Removed all these files. They have not been + used by the token library for some time. They were mistakenly + put in the release. + +Thu May 29 02:00:14 1997 <irfan@TWOSTEP> + + * ACE.cpp (is_process_active): Added this method which checks if a + process is still alive. Thanks to Chris (CLahey@cccis.com) for + this code. + + * ace/OS.i (kill): Changed PROCESS_ALL_ACCESS to + PROCESS_TERMINATE. + + * ace/ACE.cpp (bind_port): Changed the implementation of this + method such that a recently used port is not used again in the + next call to this method on Win32, i.e., upper limit is + decreased even in the successful case. This fixes the problem on + Win32 where binding to a recently used port works but the + following connect fails. + + * ace/Acceptor.cpp (close): Added a close method that allows us + to shutdown the Acceptor (without having to destroy it). + + * ace/Connector.cpp (close): Added a close method that allows us + to shutdown the Connector (without having to destroy it). + + * apps/Gateway/Gateway/Proxy_Handler_Connector.cpp + + (handle_close): Removed this method. This code seemed to be + duplicating the code in the handle_close of the proxies. + + (initiate_connection): Removed the code that did + rescheduling. The proxies are responsible for this. + + * apps/Gateway/Gateway/Event_Channel.cpp + + (initiate_proxy_connection): Must *always* use the correct synch + options while connecting. + + (reinitiate_proxy_connection): Always register for timeouts if + we are not disconnecting. This allows us to remove duplicated + logic in Proxy_Handler_Connector. + + The new logic of close() allows us to remove the code that use + to remove the proxy from the map to prevent double deletes. + + (close): Changed the shutdown logic to: Tell everyone that the + spaceship is here (behind the comet), close down the connector, + close down the acceptor, tell everyone that it is now time to + commit suicide. + + * apps/Gateway/Gateway/Proxy_Handler.cpp (handle_timeout): Must + return 0, or else the timer queue will cancel the handler and + *all* its timeouts. + + * apps/Gateway/Peer/svc.conf,Makefile: We now generate a Peer + shared library (instead of just an .so). The svc.conf was + changed to reflect this. + + * tests/UPIPE_SAP_Test.cpp: Fixed output message. + + * Handle_Set.i (operator): Fixed typo. + +Thu May 29 11:09:52 1997 David L. Levine <levine@cs.wustl.edu> + + * include/makeinclude/rules.local.GNU: check for directory + write permission before attempting to install. This helps + support shared ACE workspaces. There are two easy ways + to not install "private" libraries in the shared workspace: + 1) remove write permission from $WRAPPER_ROOT/ace, or + 2) add "INSTALL=" to invocations of "make". + +Thu May 29 06:07:18 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/OS.i (thr_join): Revised some code in the #ifdef'd out + version of ACE_OS::thr_join() so that it will compile correctly. + Note that this code isn't currently used, but someday it will + be. Thanks to Hamutal Yanay for reporting this. + +Wed May 28 16:37:57 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/OS.{h,i} (ACE_Time_Value): added default constructor, + which does not call normalize (). ACE_Time_Value::normalize () + was showing up as a relatively minor, but signficant hot + spot in Event Channel latency tests. + +Wed May 28 16:02:53 1997 James C Hu <jxh@lambada.cs.wustl.edu> + + * ace/OS.i: Changes to strdup and getpid for CHORUS, as per Wei + Chiang's suggestions. + +Tue May 27 18:26:51 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/config-hpux-10.x-decthreads.h: Added support for HP/UX 10.10 + with DCE threads. Thanks to Shankar Krishnamoorthy + <kshankar@lucent.com> for these fixes. + + * ace/Local_Tokens_T.h: #if def'd out all of this file since it + doesn't seem to be used anymore. Thanks to Shankar + Krishnamoorthy <kshankar@lucent.com> for reporting this. + + * ace/Makefile (TEMPLATE_FILES): Removed Local_Tokens_T since it + doesn't appear to be used anywhere. + +Tue May 27 18:47:34 1997 James C Hu <jxh@lambada.cs.wustl.edu> + + * tests/*.cpp: Various changes for EBCIDIC compatibility. + Thanks to Chuck Gehr for pointing out the need for this! + + * tests/test_config.h: Added ACE_ALPHABET to aid a-z sending and + comparing. + +Tue May 27 15:03:25 1997 David L. Levine <levine@cs.wustl.edu> + + * tests/Future_Test.cpp: added ACE_Future{_Rep}<int> template + specializations. + +Tue May 27 07:49:03 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/Future.cpp: Made a few minor reformatting changes to Per's + new Future enhancements. + +Tue May 27 14:19:14 1997 Per Andersson <Per.Andersson@hfera.ericsson.se> + + * ace/Future: Fixed self assignment bug in ACE_Future<>::operator=(). + Fixed bug in ACE_Future<>::set(). It is now possible to do a + ACE_Future<>::set() followed by a ACE_Future<>::get() without + hanging forever. + + Moved all handling of the ACE_Future_Rep<> reference count + into three new static ACE_Future_Rep<> member functions, + create, attach, assign and detach. + + Removed one mutex from ACE_Future_Rep<> by changing the + reference count from an ACE_Atomic_Op<int> into a plain + int. The ACE_Future_Rep<>::value_ready_mutex_ mutex is + instead used for serializing changes to the reference count. + (ACE_Future_Rep<>::attach, ACE_Future_Rep<>::detach()) + + Removed mutex from ACE_Future<> the serialization is + performed by the ACE_Future_Rep<>::attach, + ACE_Future_Rep<>::detach() and ACE_Future_Rep<>::assign() + functions. + + Changed the ACE_Future<> default constructor to always + create a ACE_Future_Rep<> + + * tests/Future_Test.cpp: Added test case for + ACE_Future<>::set() followed by ACE_Future<>::get(). Added + test for working ACE_Future::operator=(). The test is not + fool proof but it crashes or hangs the test process with the + old ACE_Future<> implementation. + +Mon May 26 14:19:14 1997 James C Hu <jxh@polka.cs.wustl.edu> + + * ace/OS.{h,i}: Fixed difftime implementation for cases where + systems implement it as a macro. Fixed tempnam by adding + ACE_LACKS_TEMPNAM. + +Sun May 25 11:36:22 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * examples/Reactor/Misc: Removed test_handle_set.cpp since it + is now completed subsumed by tests/Handle_Set_Test.cpp. + + * tests/Handle_Set_Test.cpp: Updated the test of + the ACE_Handle_Set so that it shows how fast the iterator works. + + * ace/Reactor.cpp: Updated the Reactor to use the new + ACE_Handle_Set_Iterator (whic no longer requires calling + operator++ to advance the iterator). + + * ace/Handle_Set: Rewrote the ACE_Handle_Set_Iterator to speed it up. + The result seems to be about 15% faster than the original. + + * ace/OS.h: Changed the MSB_MASK static constant into a macro and + moved it from Handle_Set.cpp into OS.h, changing its name to + ACE_MSB_MASK. + + * ace/Sched_Params.cpp (priority_max): Added another #ifdef for + Chorus. Thanks to Wei Chiang for reporting this. + + * include/makeinclude/platform_sunos5_sunc++_orbix.GNU: added -l + in front of orbixmt. Thanks to Wei Chiang for pointing this + out. + + * ace/ACE.cpp: Changed the default port for NT so that it starts + at 65279 rather than 65535. Hopefully, this will fix that + annoying bug that has been plaguing us on NT 4.0 for months. + Thanks to Goran Lowkrantz <Goran.Lowkrantz@Infologigruppen.se> + for reporting this. + +Sat May 24 23:42:32 1997 David L. Levine <levine@cs.wustl.edu> + + * performance-tests/Misc/test_naming.cpp (do_testing): replaced + strlen () calls in character array size with constant expression. + +Sat May 24 12:07:48 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * Released version 4.2.1 for testing. + + * ace/Reactor.cpp (bind): Fixed a stupid typo where I was using + the ACE_REACTOR_EVENT_HANDLER macro instead of the + ACE_REACTOR_HANDLE macro. Thanks to Detlef for reporting this. + + * ace/OS.i: Added a new macro called ACE_HAS_THR_MINSTACK to deal + with weirdo mangling of names by Tandem. Thanks to Jan Perman + <uabjjpp@osd.ericsson.se> for reporting this. + + * ace/OS.h: Added a new macro ACE_LACKS_PRI_T for those platforms + using STHREADS (e.g., Tandem NonStop OS) that don't have pri_t + defined. Thanks to Jan Perman <uabjjpp@osd.ericsson.se> for + reporting this. + + * ace/Connector.cpp (connect): Make sure to save/restore errno + since svc_handler->close() may change it. Thanks to Michael + Hartman <c62nt57@ibx.com> for reporting this. + + * include/makeinclude/platform_chorus.GNU: Added a new platform + macros file for Chorus. Thanks to Wei Chang for this. + + * ace/OS.cpp (sched_params): Reordered the #ifdefs so that Chorus + comes first. + + * ace/OS.i (sleep): If the platform defines ACE_HAS_CLOCK_GETTIME + then we'll use the nanosleep() method rather than sleep(). + + * ace/OS.h: disabled THR_NEW_LWP for Chorus. Thanks to Wei Chang + for reporting this. + + * ace/Sched_Params.cpp: ACE_SCHED_OTHER and ACE_SCHED_RR have the + same value on Chorus. Thanks to Wei Chang for reporting this. + +Sat May 24 09:21:08 1997 David L. Levine <levine@cs.wustl.edu> + + * netsvcs/lib/Server_Logging_Handler.cpp: protected second + ACE_Svc_Handler specialization for case that ACE_HAS_THREADS, + when ACE_HAS_TLI. It had gotten lost in the last pass of + that module. Thanks to Sandro Doro <doros@aureus.sublink.org> + for reporting this problem. + +Sat May 24 03:19:38 1997 Nanbor Wang <nw1@dingo.wolfpack.cs.wustl.edu> + + * ace/OS.i (sigaddset, sigdelset, sigemptyset, sigfillset, + sigismember): Modified the implementation of these function so + as to conform with POSIX standard. Basically all functions do + the same things they did but more conservative protections are + added. The modified semantic becomes, + + sigemptyset, sigfillset, sigaddset, sigdelset: return 0 if + succeed, -1 otherwise. + sigismember: returns 0 if signum is not in the set, 1 if signum + is in the set, and -1 if error occurs. + + If error occured, errno will be set to one of the following + value: + EFAULT: sigset is not a valid address. + EINVAL: signum is not a valid signal number. + + Notice that, so far, this is for NT only. + +Sat May 24 01:53:22 1997 James C Hu <jxh@polka.cs.wustl.edu> + + * performance-tests/Misc/test_naming.cpp (do_testing): Thanks to + Sandro Doro, squashed a bug where we were trying to concatenate + onto a string constant. + +Fri May 23 01:01:01 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/config-hpux-9.x.h: Added + + #define ACE_HAS_BROKEN_ENUMS + #define ACE_HAS_IP_MULTICAST + #define ACE_LACKS_GETPGID + + Thanks to Neil Cohen for reporting these. + + * ace/Thread_Manager.h: Made the private methods and data members + protected so that subclasses can extend it. Thanks to Hamutal + Yanay for this suggestion. + +Fri May 23 21:27:05 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/Process.{h,cpp} (env_argv): added "const" to char * type in + return type, for argument compatibility in call to ACE_OS::execve (). + + * ace/Process.cpp (spawn): removed unreachable return statement at + end of function. + + Thanks to Dave Mayerhoefer <mayerhoefer@svappl36.mdc.com> for + reporting the above two problems. + + * ace/{IOStream*,Makefile}: Split out templates into + ace/IOStream_T.{h,cpp} files. This way, automatic template + instantiation systems that require templates to be in separate + files, such as on Irix 6.2, will be able to build IOStream_Test + and the ACE_IOStream examples without warnings. (The + ACE_IOSTREAM_BUILDING_TEMPLATE macro that did this only worked + if ACE_TEMPLATES_REQUIRE_SOURCE was defined. It's no longer + needed with the separate template files.) + + * tests/IOStream_Test.cpp, + examples/IOStream/client/iostream_client.cpp, + examples/IOStream/server/iostream_server.cpp: + swapped ACE_Streambuf and ACE_Streambuf_T class names so that + the template class has the "_T". And renamed ACE_IOStream_T + for consistency. + + * ace/{IOStream.*,README}, + tests/IOStream_Test.cpp, + examples/IOStream/client/iostream_client.cpp, + examples/IOStream/server/iostream_server.cpp, + config-hpux-9.x*.h: + Added ACE_LACKS_ACE_IOSTREAM protection + so that these can easily be built on platforms that have + trouble with ACE_IOStream. + + * Priority_Task_Test.cpp: removed close () because it didn't really + close the Task, and added printout to main () after all tasks have + been spawned to help debug non-termination. + + * ace/OS.cpp: (thr_create, with STHREADS only): *thr_handle was + used but *thr_id had been set by ::thr_create, so threads never + got activated. Fixed by using *thr_id instead of *thr_handle + in the calls to ACE_OS::thr_setprio and ACE_OS::continue. + Thanks to Jan Perman <uabjjpp@osd.ericsson.se> for reporting + this problem. + +Fri May 23 20:12:33 1997 James C Hu <jxh@polka.cs.wustl.edu> + + * tests/SV_Shared_Memory_Test.cpp: Thanks to Chuck Gehr, fixed + ASCII dependent code in the parent and child routines. + +Fri May 23 02:58:28 1997 Nanbor Wang <nw1@siesta.cs.wustl.edu> + + * ace/OS.i (dlsym): Added ACE_USES_ASM_SYMBOL_IN_DLSYM, support + for platforms (FreeBSD) which use assembly symbols instead of C + symbols in dlsym (). + + * ace/config-freebsd[-pthread].h: Added flag ACE_HAS_CHARPTR_DL + and ACE_USES_ASM_SYMBOL_IN_DLSYM. + +Thu May 22 08:14:21 1997 David L. Levine <levine@cs.wustl.edu> + + * tests/Tokens_Test.cpp: added deletes to avoid memory leaks. + +Wed May 21 16:15:48 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/{config-irix6.2*.h,README}: removed ACE_LACKS_IOSTREAM_SETGET + because tests won't build with it. Also, added + ACE_LACKS_SIGNED_CHAR. + + * ace/IOStream.h: removed "const" from PUT_PROT of + u_char * and void *. This should allow the IOStream test + and examples to build and run on Irix platforms. Thanks + to Torbjorn Lindgren <tl@funcom.com> and Amos Shapira + <amos@dsi.co.il> for reporting this, and to James Hu for + helping fix it. + + * ace/{OS.cpp,Sched_Params.cp} (Solaris only): use 0 min priority + again, with workaround in ACE_OS::thr_create to not use + ::pthread_attr_setschedparam () if the priority is 0. Instead, + the priority of the newly created thread is set to 0 (if it + wasn't created with 0) after the thread is created, with + ::pthread_setschedparam (). + +Wed May 21 15:23:37 1997 Chris Cleeland <cleeland@cs.wustl.edu> + + * ace/Strategies_T.* (ACE_Hash_Addr): Eliminated the ADDR_T + template parameter as a base class. It is now a wholly-contained + member of the ACE_Hash_Addr<> with conversion operators. + This caused problems on certain compilers, notably HP-UX. + +Wed May 21 14:13:36 1997 James C Hu <jxh@polka.cs.wustl.edu> + + * ace/OS.{h,i} (difftime): Added implementation to ACE_OS. I + don't expect any problems since it is in ANSI. + + * ace/OS.{h,i} (tempnam): Added implementation to ACE_OS. + +Wed May 21 01:17:40 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * Released version 4.2. + + * ace/Acceptor.cpp (activate_svc_handler ): Removed an unnecessary + return 0. Thanks to Amos Shapira <amos@dsi.co.il> for reporting + this. + + * ace/Message_Block.cpp (release): I believe that + ACE_Message_Block::release() should return something other than + 0, i.e., it should return the result of release_i(). Thanks to + Amos Shapira <amos@dsi.co.il> for reporting this. + +Wed May 21 01:17:40 1997 Per Andersson <Per.Andersson@hfera.ericsson.se> + + * Moved most code from netsvcs/lib/Server_Logging_Handler.* to + Server_Logging_Handler_T.*. Made template out of + ACE_Server_Logging_Handler and ACE_Server_Logging_Acceptor. + Factorised out as much as possible to reduce code + duplication. The log record processing was moved from + ACE_Server_Logging_Handler it should now be handled by the + Log_Message_Receiver class. It is now possible to change + how log records processed without changing code in + Server_Logging_Handler* and it is possible to have several + Server_Logging_Handlers that processes log records + in different ways without duplicating all the server code. + All that is needed is to write a new/change + Log_Message_Receiver and instantiate a couple of templates. + + * netsvcs/lib/Server_Logging_Handler.h added lots of typedefs + for making template instantiations easier. + + * netsvcs/lib/Server_Logging_Handler.h addad lots template + instatiations, there are now 58 all together. + + * Added netsvc/lib/Log_Message_Receiver.{h,cpp}, implementstwo + simple log message receivers that prints the log record to + stderr. + +Tue May 20 13:50:17 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/config-hpux-9.x.h: Added a #define for ACE_HAS_BROKEN_ENUM, + ACE_HAS_IP_MULTICAST, and ACE_LACKS_GETPGID. Thanks to Neil + Cohen for reporting this. + + * include/makeinclude/platform_sunos5_sunc++_orbix.GNU: Replaced + the use of -lITsrv with -lorbixmt. Thanks to Wei Chiang for + this. + + * include/makeinclude/platform_osf1_3.2.GNU: Make sure that all + the template repositories are in the same directory to work + around problems with the C++ compiler. Also added -lrt to get + the apps and tests to run. Thanks to Tom Dobridge for this + help. + +Tue May 20 17:13:15 1997 Carlos O'Ryan <coryan@charlie> + + * ace/config-hpux-10.x-nothread.h: + * ace/config-hpux-10.x-aCC.h: + * ace/Stream_Modules.cpp: + ACE_LACKS_STREAM_MODULES is no longer needed, moving the inclusion + of "ace/Task.h" to the beginning of "ace/Stream_Modules.h" solved + the problem nicely. + + * ace/config-hpux-10.x.h: + * ace/config-hpux-10.x-aCC.h: + ACE_HAS_BROKEN_HPUX_TEMPLATES is not needed on newer HP/CXX + compilers; further, old ones will not compile ACE even if the + macro is defined. + + * ace/Timer_List_T.h: + * ace/Timer_Queue_T.i: + I moved the definition of ACE_Timer_Queue_T::lock() from the .i + file to the .h file, HP/CXX gets completely confused otherwise. + I also added a number of ACE_INLINE missing in the .i file. + + * ace/Stream_Modules.h: + * ace/Stream_Modules.cpp: + I had to move the inclusion of "ace/Task.h" outside of the + protections against multiple inclusion for Stream_Modules.h. + That seems to solve the ciclyc dependancy for + Task->Module->Stream_Module->Task. + BTW, the same thing was already done in "ace/Log_Record.h". + I'll try to remove the ACE_LACKS_STREAM_MODULES macro, it seems + that the last change makes it redundant. + + * ace/Signal.cpp: + HP/CXX compiler will not close the library unless + ACE_MAX_SIGNAL_HANDLERS is defined as "const size_t". The previous + definition ("size_t") did compile tough. + + * ace/Log_Record.h: + We need to include "ace/ACE.h" before "ace/Log_Priority.h". + + * ace/Log_Priority.h: + HP/CXX compiler seems to reserve a few bits in enums, so the + ENSURE_32_BITS trick would result in a compile time error. + Since HP enums are always 32 bits we could skip the definition for + ENSURE_32_BITS altogether, but I prefer to keep a consistent + namespace across plaforms, I have found a value for ENSURE_32_BITS + that seems to work. + + * include/makeinclude/platform_hpux.GNU: + Some options to improve compile time, since we use explicit + template instantiation there is no need for a ptcomp o ptlink + phase. + +Tue May 20 09:10:18 1997 Nanbor Wang <nw1@number.wustl.edu> + + * ace/config-freebsd-pthread.h: + * ace/config-freebsd.h: Removed "FreeBSD" directive because gcc on + FreeBSD defines __FreeBSD__ automatically. + + * ace/OS.i (sigaddset, sigdelset, sigismember): Added range + checking to these functions in order to avoid disasters. Sig + number should be between 1 and NSIG. + (sigwait): Changed ifdef (FreeBSD) to ifdef (__FreeBSD__) since + compiler does it for us. + +Tue May 20 08:41:11 1997 David L. Levine <levine@cs.wustl.edu> + + * examples/Threads/tss2.cpp: added #include of ace/Thread.h + because Sun C++ 4.1 needs it. + +Mon May 19 16:04:32 1997 David L. Levine <levine@cs.wustl.edu> + + * bin/create_ace_build: changed startup line for compatibility + with bash.

Thanks to Chuck Gehr for + reporting this. + +Sun May 18 21:57:54 1997 David L. Levine <levine@cs.wustl.edu> + + * examples/Threads/tss2.cpp: added second parameter to + ACE_TSS_Singleton template specialization. + +Sun May 18 09:20:15 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * examples/Threads/TSS_Data.h: Added the second parameter for + ACE_SYNCH_MUTEX since Rich and Chris updated ACE_TSS_Singleton. + + * ace/Singleton.cpp: Added the updated version of + ACE_TSS_Singleton that implements the Double-Checked Locking + pattern. Thanks to Rich Christy and Chris Lahey for this. + + * ace/Strategies_T.cpp (activate_svc_handler): Fixed the logic so + that a value is always returned. Thanks to David Levine for + noticing this. + +Sun May 18 07:25:11 1997 David L. Levine <levine@cs.wustl.edu> + + * netsvcs/lib/Server_Logging_Handler.cpp: removed second + ACE_Svc_Handler specialization for non-threaded, has-TLI case. + That's because it is the same as the first; the only difference + was that one specialized with ACE_SYNCH and the other with + ACE_NULL_SYNCH. Without threads, those macros expand to the + same thing. Thanks Sandro Doro <doros@aureus.sublink.org> for + reporting this. + + * examples/Threads/tss2.cpp: added ACE_TSS<TSS_Data> template + specialization. + +Sat May 17 23:24:34 1997 Nanbor Wang <nw1@number.wustl.edu> + + * ace/OS.i (sigismember): Corrected the code when + ACE_LACKS_SIGSET. + +Sat May 17 00:06:04 1997 <irfan@TWOSTEP> + + * examples/ASX/Event_Server/Transceiver/transceiver.cpp + (Event_Transceiver): Corrected signal registration for Win32. + + * apps/Gateway/Gateway/Gateway.cpp (parse_args): Since the + Connector is now fixed, non-blocking is now working fine. + + * ace/Connector.cpp (handle_close,create_AST): Made sure we close + down the svc_handler on error. + + * ace/{Acceptor.cpp,Connector.cpp} (activate_svc_handler): The + if statement logic in these methods was incorrect. + + * ace/SOCK_Connector.cpp (connect): Just like in complete(), we + start out with non-blocking disabled on the <new_stream>. + + * ace/OS.h: When ACE_LACKS_SIGSET is defined, changed the + definition of sigset_t from void * to unsigned int. + +Sat May 17 12:25:22 1997 Douglas C.

Schmidt <schmidt@flamenco.cs.wustl.edu> + + * netsvcs/lib: Reverted back to the original Server_Logging_Handler + behavior since the new version is breaking GCC's templates. + + * ace/Log_Record.h: need to #include "ace/ACE.h" before + "ace/Log_Priority.h" so that "Log_Priority.h" sees the + configuration stuff (otherwise the following fix won't work). + + * ace/Log_Priority.h: Added a workaround for lame C++ compilers + like the one on HP/UX that can't support large enums. Thanks to + Robert Head for reporting this. + + * ace/Singleton: Added the new ACE_TSS_Singleton, which stores + Singletons in thread-specific storage. Thanks to Chris Lahey + and Rich Christy <rchristy@cccis.com> for this. + + * ace/OS.h: Removed the ACE_Singleton_Strategy since we don't need + it anymore. + + * netsvcs/lib: Added the new Server_Logging_Handler_T.* and + Log_Message_Receiver.* netsvcs.

Thanks to Thilo for this. + + * include/makeinclude/platform_chorus.GNU: Removed CLASSIXDIR = + /usr/home/chiang/chorus/merge/extended-i386at, added the + nostdinc flag, and removed extra whitespace. Thanks to Wei + Chiang for reporting this. + +Fri May 16 00:02:33 1997 <irfan@TWOSTEP> + + * ace/ReactorEx: Even though changes to the owner field are very + well synchronized within the class code, the owner() + accessor is public and can be called from out side the + class. Therefore, I have added a owner_i() that does not do + locking. All internal calls to check the owner will use the + new accessor, whereas application code outside the class can + still use the old synchronized accessor. + +Fri May 16 11:39:51 1997 Nanbor Wang <nw1@cs.wustl.edu> + + * ace/OS.i (sigaddset, sigdelset, sigemptyset, sigfillset, + sigismember): Added implementation when ACE_LACKS_SIGSET so that + platforms (NT?) without these functions can still manipulate + sigset_t variables. + +Thu May 15 22:19:59 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * examples/ASX/Event_Server/Event_Server: Removed the THR_DETACHED + flag from options so that we can wait on the threads + correctly. + + * ace/Stream_Modules.cpp: Changed the logic for determining when + to compile the Stream_Modules.cpp code. Now, we compile it + unless ACE_LACKS_STREAM_MODULES is defined (i.e., we're on HP/UX + 10.x using aCC). + + * netsvcs/lib/Server_Logging_Handler.cpp (handle_input): Fixed + a bug in handle_input() where we need to return the result, not + just 0 or 1. Thanks to Per Andersson for reporting this. + + * ace/Log_Priority.h: Changed the values of the enums in + ACE_Log_Priority so that they can be dealt with via bitwise + operations. Thanks to Per Andersson for this. + + * include/makeinclude/platform_osf1_4.0.GNU: Added support for + templates. Thanks to Steve Huston and James Johnson for + verifying this. + + * include/makeinclude/platform_osf1_3.2.GNU: Got rid of all + unresolved symbol warnings using cxx 5.5 on DEC/OSF v3.2 by + using the linker flag "-expect_unresolved '*'." In addition, I + added -threads to the DCFLAGS macro. Thanks to Tom Dobridge + <dobridge@persimmon.com> for this. + + * ace/Strategies_T: Added a minor ACE_Reactive_Strategy extension + to enable non-blocking I/O in active_svc_handler(). Thanks to + Arturo Montes <mitosys@colomsat.net.co> for contributing this. + + * ace/config-osf1-4.0[-g++].h: Added a #define for + ACE_POLL_IS_BROKEN since DEC UNIX's poll() doesn't seem to work + correctly as a highres timer. Thanks to James Johnson and Thilo + for reporting this. + + * examples/Threads/thread_specific.cpp (worker): Changes + size_t i back to int i to avoid a signed/unsigned complaint. + Thanks to David Levine for reporting this. + + * ace/config-chorus.h: Added ACE_LACKS_MPROTECT, + ACE_HAS_IP_MULTICAST, and ACE_LACKS_SOCKETPAIR to the Chorus + port. Thanks to Wei Chiang <chiang@erebor.tele.nokia.fi> for + reporting this. + + * ace/OS.i: Added ACE_LACKS_ACCESS to the Chorus config file + and VxWorks config file, as well as to OS.i. + +: * ace/OS.i: Added ACE_LACKS_GETSERVBYNAME to the Chorus config + file and VxWorks config file, as well as to OS.i. + + * ace/OS.i: Added ACE_LACKS_SBRK to the Chorus config file, as + well as to the definition of the ACE_OS::sbrk() function. + + * ace/OS.h: Removed #include /**/ <pwd.h> from the Chorus-specific + part of OS.h since it's already included elsewhere. Thanks to + Wei Chiang <chiang@erebor.tele.nokia.fi> for reporting this. + + * ace/Reactor: Added a typedef for ACE_Reactor_Token to + ACE_Null_Mutex for situations where ACE_MT_SAFE is *disabled*. + This makes the code more consistent. + + * ace/Reactor: Added an interface that makes it possible to + acquire a reference to the <ACE_Reactor_Token> that is used to + serialize the internal Reactor's processing logic. This can be + useful for situations where you need to avoid deadlock + efficiently when <ACE_Event_Handlers> are used in multiple + threads.

HP/CXX (version 10.24) support explicit template + instantiation, I believe this to be a superior method for + ensuring library closure (and it works). + + * ace/Task_T.cpp: + * ace/Stream_Modules.cpp: + I have changed the hack to compile under HP-UX, + "ace/Module.h" is once more included in ace/Task_T.cpp, but + "ace/Stream_Modules.cpp" is protected: it will be empty + under HP-UX unless included from the + "ace/Stream_Modules.h". I still believe that there is a + problem in the cyclic dependancy Task -> Module -> Thru_Task + -> Task; but it seems that the current hack works better. + + * ace/OS.h: + Defining ACE_UNUSED_ARG as (a) for HP/CXX does not work so I + moved it to the SGI and GCC definition. + + * ace/OS.i: + More unused args. + + * ace/Handle_Set.h: + Removed the extra qualification for ACE_Handle_Set::NBITS, + HP/CXX sends a lot of warnings with that. + + * ace/IOStream.h: + It included "IOStream.cpp" I think that "ace/IOStream.cpp" + is better. + + * ace/Local_Name_Space_T.h: + Ditto for "Local_Name_Space.h" + +Thu May 15 17:40:06 1997 <irfan@TWOSTEP> + + * ace/ReactorEx.i (owner): Since changes to the owner field are + very well synchronized, we do not need to synchronize this + accessor. + + * ace/IOStream.h: Added /**/ after #include directives. + + * ace: Update Win32 makefiles to include UNICODE make option. + +Thu May 15 08:54:53 1997 David L. Levine <levine@cs.wustl.edu> + + * Makefile (release, cleanrelease): use -prune option to "find" + instead of filtering its output. Thanks to Chris Cleeland for + suggesting this. + +Wed May 14 21:52:22 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/UPIPE_Stream.cpp (control): We need to "cast away const" so + that this method can call the Stream's control() method + (which is non-const). Thanks to David Levine for locating this. + + * ace/Singleton.cpp: Finished re-implementing ACE_Singleton. + + * examples/ASX/Message_Queue/buffer_stream.cpp: Updated this + example to illustrate (1) how filters work in an ACE_Stream and + (2) to make sure that resizing buffers work. + + * ace/UPIPE_Stream.h: Changed the signature of control() + to take an int so that it will match the base class + signature. + + * ace/Singleton.h: The new ACE_SingletonEx isn't working yet. + I've #ifdef'd it out until it works. + + * examples/Threads/tss2.cpp: Updated this test program to + illustrate the use of the new ACE_SingletonEx class. + + * ace/Singleton.h: Added a new instance() method to the ACE + Singleton that can be used to set the Singleton. This is useful + for situations where the type being used as the Singleton + doesn't have a default constructor. Thanks to Arturo Montes + <mitosys@colomsat.net.co> for this suggestion. + + * ace/Singleton: Factored out common code in the Singleton and + SingletonEx implementations so they will be cleaner and more + portable. + + * ace/Local_Name_Space_T.h, + ace/Map_Manager.h, + ace/Hash_Map_Manager.h, + ace/SString.h, + ace/Hash_Map_Manager.cpp: + + Changed all uses of the identifier "allocator" to "alloc" to + avoid conflicts with MSVC++ STL 5.0. Thanks to William + L. Gerecke <gerecke@rayva.org> for reporting this. + + * ace/config-aix-4.[12].x.h: Replaces + ACE_LACKS_PTHREAD_THR_SIGSETMASK with ACE_HAS_SIGTHREADMASK. + Thanks to Chris Lahey for this. + + * ace/OS.i (thr_sigsetmask): Added the ACE_HAS_SIGTHREADMASK + support for AIX. Thanks to Chris Lahey for this. + + * ace/Singleton: Added the new ACE_SingletonEx, which supports + both heap-based and thread-specific storage-based Singletons. + Thanks to Chris Lahey for this. + + * ace/OS.h: Added the new ACE_Singleton_Strategy to OS.h. Thanks + to Chris Lahey for this. + +Wed May 14 16:32:57 1997 David L. Levine <levine@cs.wustl.edu> + + * Makefile: use cpio instead of tar to allow easy filtering + of CVS files from the release. + +Wed May 14 15:00:58 1997 <irfan@TWOSTEP> + + * examples/IPC_SAP/SOCK_SAP/CPP-inclient.cpp (main): Fixed code. + + * examples/Naming: Replaced multiple makefiles with one makefile. + + * ace/OS.h: Added UNICODE support for some #defines. + + * OS.i (vsprintf): Added support for this in ACE_OS. + + * OS.cpp (socket_init && socket_fini): It is ok to print out cout + and cerr messages from here (as the C runtime library is still + attached) but it is *not* ok to print out ACE_DEBUG + messages. God only knows the state of the thread specific LogMsg + instance when the process reaches this piece of code. + + Also added a (handy) sprintf that has the following prototype: + + sprintf (wchar_t *buf, const char *format, ...) + + * ace/Process: UNICODE fixes. + + * tests: Fixed the following such that they work with UNICODE: + + Pipe_Test.cpp + Process_Mutex_Test.cpp + Process_Strategy_Test.cpp + Time_Service_Test.cpp + Tokens_Test.cpp + + * Time_Service_Test.cpp (main): Fixed typo in the svc.conf + filename for the clerk. + +Tue May 13 18:56:27 1997 Douglas C.

I fixed it. + + * ace/UPIPE_Stream.cpp (close): I am not sure why the stream was + closed with M_DELETE_NONE. This indicates that close() should + not delete any Tasks. This caused a memory leak as the Tasks in + the Tail and Head modules were not deleted.

Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/config-aix-4.[12].x.h: Added ACE_HAS_EXCEPTIONS to + the AIX 4.* config files. Thanks to Chris Lahey for this. + +Mon May 12 13:49:54 1997 <irfan@TWOSTEP> + + * ace/Thread_Manager.cpp (wait): We have to make sure that while + we wait for these threads to exit, we do not have the + lock.

The + Thread Manager will handle this correctly. + + * ace/ACE.cpp (register_stdin_handler): Changed the options such + that the Thread Manager used for the adapter is passed along to + the method executed by the new thread. We can then notify the + thread manager when this adapter thread exits. + + * examples/ASX/Event_Server/Event_Server: Changed the way the + reference count was being kept on the context. Now, the + reference count starts with zero and every instance and every + active Task increments it. This works well as Task::close() is + called one from the module being deleted and from the active + thread going away. + +Mon May 12 11:11:51 1997 <harrison@samba.cs.wustl.edu> + + * ace/Process.*: Removed the old ACE_Process and replaced it with + what was ACE_ProcessEx. + + * ace/Process_Manager.{i,cpp}: Updated to use the new ACE_Process + API. + +Mon May 12 08:16:38 1997 David L.

Since *many* data blocks can share + the same lock, for the case of message block chains, we would + like to optimize locking. + + Therefore, the first guy in the chain grabs the lock and passes + it to the continuation chain. When each guy in the chain gets + it, it compares the passed lock to its own locking strategy. If + it is the same lock, no need to acquire the lock again. If our + lock is different, then we do our own locking. + + * tests/Simple_Message_Block_Test.cpp: This test program is a + torture test that illustrates how ACE_Message_Block reference + counting works, how and when locks are used, how memory is + managed, and how continuation chains of message blocks are + made.

This was a hack to simplify + the locking issues! However this optimization leaded to + incorrect code. Therefore I have taken this behavior out. The + new implementation will lock and unlock multiple times in the + case when there are message_blocks in the continuation field, + all of which point to same data block. However, this is a + strange case that can be optimized later. For now correct code + is more important. + + Also, the continuation message blocks are only deleted in the + release() method and not in the destructor. This will ensure + that if message blocks of the stack are chained together, we + will not call release on message blocks of the stack. + + Also note that release() should only be called on message blocks + that have been dynamically allocated. Message blocks of the + stack will clean up properly when the activation record of the + method completes. Dynamically allocated messages blocks should + *never* be chained with message blocks allocated of the stack. + + * examples/ASX/Event_Server/Event_Server/Peer_Router.h: Removed + empty definitions of assignment operator and copy constructor. + + * examples/ASX/Event_Server/Event_Server/event_server.cpp + (handle_input): Added code here will make sure we actually wait + for the user to type something.

Thanks to Karlheinz for reporting this + and to Irfan for helping to fix it. + + * ace/OS.i: Fixed a very subtle bug with ACE_OS::cond_wait() and + ACE_OS::cond_signal() that only manifests itself when + ACE_HAS_SIGNAL_OBJECT_AND_WAIT is enabled (which isn't the + default). The problem stemmed from the fact that we were + assuming that if we used condition variables it implied that the + external mutex had USYNC_PROCESS scope. In fact, the external + mutexes typically have USYNC_THREAD scope, so + SignalObjectAndWait() was hanging indefinitely. Fortunately, + the fix was easy -- just add a run-time check for the type of + the external mutex and take the appropriate action.

It appears that SGI IRIX 6.2 supports + pread() and pwrite() so I enabled the ACE_HAS_P_READ_WRITE macro + in the IRIX 6.2 config file. + + * ace/OS.cpp: Implemented ACE_OS::pread() and ACE_OS::pwrite() for + systems that lack this feature. The implementation uses the new + ACE_Thread_Mutex monitor lock in order to ensure atomicity + between the lseek() and the read()/write(). + + * ace/OS.cpp: Finally broke down and added a ACE_Thread_Mutex + monitor lock to the ACE_OS implementation file.

These default to ACE_MT_SYNCH::MUTEX and + ACE_MT_SYNCH::MUTEX if template typedefs are supported and + ACE_HAS_THREADS is enabled. If template typedefs *aren't* + supported but ACE_HAS_THREADS is enabled these macros turn into + ACE_Thread_Mutex and ACE_Thread_Condition.

These macros make it + possible to write code that is more portable across platforms + and configurations. Thanks to Carlos O'Ryan for this + suggestion. + + * ace/OS.h: Replaced all uses of ACE_SYNCH_MUTEX and + ACE_SYNCH_CONDITION with ACE_SYNCH_MUTEX_T and + ACE_SYNCH_CONDITION_T since (1) this usage relates to templates + and (2) it frees up the namespace for the new ACE_SYNCH_MUTEX + and ACE_SYNCH_CONDITION macros. + + * ace/Timer_Queue.cpp: Added yet more template specializations for + the benefit of GCC (ugh). + + * ace/Timer_Wheel_T.cpp: Had to revise things just a bit to + compile with GCC and it's lame template mechanism.

The following files were updated: + + Proactor.cpp Timer_Heap.cpp Timer_List.cpp Timer_Queue.cpp + Timers.cpp + +Thu Apr 24 21:13:51 1997 <irfan@TWOSTEP> + + * ace/Timer_Queue: Decoupled the Timer Queue from + ACE_Event_Handler and the callback routines in the handler + (handle_timeout and handle_close). The new Timer Queue is + parameterized by the type of data to store and a FUNCTOR on + which methods are invoked by the Timer Queue when timeouts and + cancellations occur. + + No changes occured to the algorithms of the different + implementations of the Timer Queues (Timer List and Timer + Heap). Timer Queues, Timer List, and Timer Heap were all renamed + as <class>_T. However, typedef were added such that there is now + an ACE_Timer_Queue, ACE_Timer_Heap, and ACE_Timer_List, each + being an instantiation of the respective template classes. The + instantiation is done with ACE_Event_Handler as the type of data + to be stored in Timer Queue and + ACE_Event_Handler_Handle_Timeout_Upcall as the FUNCTOR that does + the appropriate upcall to ACE_Event_Handler. + + Due to these typedefs, 99.9% of existing code should not + break. However, the following two will cause problems: + + (a) Forward declarations of Timer_Queue will not work! This is + because Timer_Queue is now a typedef and not a class. + + (b) #include "ace/Timer_Queue.h" will not be enough to get the + ACE_Timer_Queue typedef. The new typedefs are in a new file + called Timers.h. This file also has typedefs for ACE_Timer_Heap + and ACE_Timer_List. + + Currently Proactor is the only class that uses a different + instantiation of the Timer Queue class. Proactor's Timer Queue + class is instantiated with ACE_Handler as the type of data to be + stored in Timer Queue and ACE_Proactor_Handle_Timeout_Upcall as + the FUNCTOR that does the appropriate posting to the Proactor's + completion port. + + The Upcall Strategy is not needed any more cause it is replaced + by the FUNCTORs. Thus this is removed. + + Small modifications were made to the following files + because of the changes to Timer_Queue. + + - examples/Reactor/Misc/test_timer_queue.cpp + - examples/Reactor/Proactor/test_timeout.cpp + - tests/Timer_Queue_Test.cpp + - ace/Makefile (both UNIX and Win32) + - ace/Connector.h + - ace/Reactor.h + - ace/ReactorEx.h + - ace/Proactor.h + + * ace/Proactor: Proactor now uses the new timer queues. Proactor's + Timer Queue class is instantiated with ACE_Handler as the type + of data to be stored in Timer Queue and + ACE_Proactor_Handle_Timeout_Upcall as the FUNCTOR that does the + appropriate posting to the Proactor's completion port. This will + help reduce the overhead of creating new act for each + timer. This also enables the cancellation of entire + ACE_Handlers. + + * examples/Reactor/Misc: Added Win32 makefiles. + + * ace/Shared_Memory_MM.i: Fixed typo. + + * ace/SOCK_Connector.cpp: Fixed typo. + +Thu Apr 24 13:56:28 1997 Douglas C.

Manual switching between + alpha/beta and final release "modes" is therefore still required. + + * ace/Timer_Heap.cpp (copy): added cast of max_size_ to int to avoid + signed/unsigned comparison. + + * ace/config-sunos5.4-g++.h: removed + ACE_HAS_CONSISTENT_SIGNAL_PROTOTYPES because it caused compile + warnings about conversion from `(int)' to `(...)' at Signal.i:113. + (And the other sunos5.4 config files don't have it.) + Thanks to Joey Zhu <joey.zhu@wcom.com> for reporting this. + + * tests/Timer_Queue_Test.cpp (main): added delete of timer_ids array + to avoid memory leak. + +Wed Apr 23 22:56:57 1997 Sumedh Mungee <sumedh@cs.wustl.edu> + + * apps/JAWS/client/*: Fixed warnings due to size_t + * apps/JAWS/client/Blob_Handler: Fixed error by passing + pointer to base class ACE_Blob_Handler instead + of pointing to ACE_Blob_Reader, in call to connect + +Wed Apr 23 20:57:35 1997 James C Hu <jxh@polka.cs.wustl.edu> + + * ace/OS.i and ace/OS.h: added methods for getpwnam and + getpwnam_r, with hooks for NT. + + * ace/config-irix6.2.*: added ACE_LACKS_PWD_REENTRANT_FUNCTIONS. + +Wed Apr 23 14:27:48 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/Timer_Queue.cpp (ACE_Timer_Queue ctor): reordered initializers + to match declaration order. + + * tests/Process_Strategy_Test.cpp: added ACE_Singleton template + specialization. In function client (), null terminated "buf" + before call to ACE_OS::strrchr () to avoid uninitialized memory + read. Also, fixed typo in test name (argument to ACE_START_TEST). + + * examples/Service_Configurator/Misc/Timer_Service.cpp (init): changed + type of loop index to int to avoid signed/unsigned comparison, and + initialized "interval" so that it has a value even if one isn't + specified on the command line. + +Wed Apr 23 10:52:45 1997 Chris Cleeland <cleeland@cs.wustl.edu> + + * ace/OS.cpp (thr_create): Removed errant preprocessor conditional + for determining the scheduling priority.

Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/Synch.cpp: Added a new method called open() to ACE_File_Lock + so that we don't have to initialize it solely in the + constructor. + + * tests/Process_Strategy_Test.cpp: Added new test code that + exercises the ACE_Process_Strategy, ACE_Thread_Strategy, and + ACE_Reactive_Strategy classes. + + * ace/Strategies_T: Added a new class called + ACE_Reactive_Strategy, which inherits from + ACE_Concurrency_Strategy and registers new Svc_Handlers with the + Reactor. + + * ace/Strategies_T.cpp (ACE_Thread_Strategy): Added a check for + failed open() methods and call ACE_ERROR. + + * tests/Map_Manager_Test.cpp: Added a template specialization for + the ACE_Hash_Map_Manager::hash() method, which is enabled if the + compiler supports template specializations. + + * ace/Hash_Map_Manager.h (pool): Moved the ext_id.hash() call into + a separate method so that we can perform template specialization + of it more easily. + + * ace/README: Added a new #define called + ACE_HAS_TEMPLATE_SPECIALIZATION so that we can work around funky + compilers that don't support this advanced template feature. + + * ace: Added Nanbor Wang's port to FreeBSD. The port is done + at FreeBSD 3.0-current as of 2/9/97, which is the + latest stable system before Lite2 merge. Since the merge is + current under testing and changes are introduced in a daily + basis, I don't recommend using -current after the date. You + can specified the date in your "supfile", run CVSup to get the entire + source tree and do a 'make world' to update (or reverse) your + system. + + Pthread library is provided by John Birrell. There is a + bug fix at mid April so you may want to CVSup the latest libc_r + library and re-make the pthreaded library. + + A shared library must be name as lib<name>.so.<version + number> (e.g. libACE.4.1.0). I would recommend adding a + post-compile hook in the Makefile so we FreeBSDers can + rename the shared library to it's proper name with correct + major and minor version number attached. (which is a trick + BSD library makefiles use.) + + * examples/OS/Process/process.cpp (main): Replaced the use of + "/bin/cat" with "cat" since we are now using execvp(). Thanks + to Nanbor Wang <nw1@cs.wustl.edu> for reporting this. + + * ace/Process.cpp (start): Changed the use of execv() to execvp() + in order to avoid having to pass in the full pathname. + + * ace/OS.i (sigwait): Added an #ifdef for FreeBSD so that we + return ACE_NOTSUP_RETURN(-1) for ACE_OS::sigwait(). Thanks to + Nanbor Wang <nw1@cs.wustl.edu> for reporting this. + +Tue Apr 22 17:46:30 1997 <harrison@samba.cs.wustl.edu> + + * Process.cpp (start): We must pass in 0 instead of "" to + CreateProcess for the current working directory. + +Tue Apr 22 01:38:14 1997 <irfan@TWOSTEP> + + * ace/Timer_Queue: Added ACE_Upcall_Strategy as a parameter to the + constructor. <expire> will call <upcall_strategy->upcall> if + <upcall_strategy> is not 0. Else it will call <handle_timeout> + on the <Event_Handler>. Thus ACE_Upcall_Strategy becomes a + vehicle for extending the behavior of ACE_Timer_Queue wrt the + upcall (callback) *without subclassing*. Hence, it's an example + of the Bridge/Strategy patterns. + + This also affected ACE_Timer_List and ACE_Timer_Heap + + * ace/Strategies: Added ACE_Upcall_Strategy. + + * ace/Proactor: Added timing support to the <handle_event> calls. + + * ace/Asynch_IO: ACE_Handler now supports handle_timeout. + + * ace/Proactor: Added timer support for the new Proactor. This + new scheme allows any of the threads in the "thread pool" + waiting on the completion port of the Proactor to execute the + callback routine of the handler. + + The implementation included adding ACE_Proactor_Timer_Handler + class that has a thread that will wait on the earliest time in a + timer queue and an event. When a timer expires, the thread will + post a completion event on the port and go back to waiting on + the timer queue and event. If the event is signaled, the thread + will refresh the time it is currently waiting on (in case the + earliest time has changed). + + The ACE_Proactor::Asynch_Timer class is posted to the completion + port when a timer expires. When the <complete> method of this + object is called, the <handler>'s handle_timeout method will be + called. + + * examples/Reactor/Proactor/test_timeout: This example illustrates + the new timer features in the Proactor + + * examples/Reactor/Proactor/test_proactor.{mdp,mak}: Added new + example. + +Mon Apr 21 18:14:32 1997 Irfan Pyarali <irfan@flamenco.cs.wustl.edu> + + * ace/config-win32-common.h: Added checks around _AFXDLL before + defining it.

This is necessary since the compiler will + auto generate these two operations that will end up using the + non-existent copy constructor and assignment operator from the + TSS class and cause linker errors. + +Sun Apr 20 20:47:34 1997 Sumedh Mungee <sumedh@cs.wustl.edu> + + * apps/JAWS/client: Reworked the ACE_Blob* classes to work + with the new Connector behavior. Added README for this + directory. Added comments. + + * apps/JAWS/stress-testing: Added README file + +Sun Apr 20 13:11:25 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * apps/Makefile: By default, we now compile JAWS along with the + rest of ACE. I've also added some README files that explain + what JAWS is all about. + + * examples/Service_Configurator/Misc/Timer_Service: Improved the + Timer_Service test so that it makes more sense and is better + documented. + +Sat Apr 19 11:56:35 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * include/makeinclude: Removed the platform_irix6.2_sgiCC.GNU + from the release.

Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/Memory_Pool.h: Fixed a couple of typos in Memory_Pool + classes. Thanks to Neil B. Cohen <nbc@metsci.com> for reporting + this. + + * netsvcs/lib/Name_Handler.h: Arrgh, there was still one more + missing #include that I forgot to move into the *.h file. + Thanks to David Levine for noticing this. + + * ace/Synch.cpp (wait): There was a bug in + ACE_Condition::wait(MUTEX& mutex, const ACE_Time_Value + *abstime.) Basically when abstime is zero, it ignores the + parameter "mutex" that has been passed to it and instead goes on + to call "ACE_Condition<MUTEX>::wait()" which uses "this->mutex_" + as the mutex to be released and not the mutex that the caller + has given. The fix is to change the call "this->wait()" in the + if-clause to: + + return ACE_OS::cond_wait (&this->cond_, &mutex_.lock_); + + Thanks to Ashish Singhai <Ashish.Singhai@ACM.ORG> for reporting + this. + +Thu Apr 17 16:33:21 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/Memory_Pool.cpp: fixed typos in ACE_MMAP_Memory_Pool_Options + constructor declaration and initializer list. In init_acquire, + added cast of minimum_bytes_ to size_t to avoid signed/unsigned + comparison. + + * include/makeinclude/{platform*,wrapper_macros}.GNU: + moved -g out of wrapper_macros.GNU and into each platform + file so that -gstabs can be used on SCO. Thanks to + Ganesh Pai <gpai@voicetek.com> for reporting that problem. + + (The real change was getting rid of the CFLAGS += DCFLAGS + default. We could have left DCFLAGS=-g in wrapper_macros.GNU + and overridden for SCO. But the way I changed things, the + C/CFLAGS pieces are together in each platform file, so they're + easier to find.) + +Wed Apr 16 17:05:55 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/Memory_Pool.cpp (acquire): Added code to enable a minimum + bytes field with the Shared_Memory_Pool. Thanks to Fred LaBar + <flabar@fallschurch.esys.com> for these enhancements. + + * tests/Process_Strategy_Test.cpp: Only compile this test if + ACE_LACKS_EXEC is *not* defined since ACE_Process_Strategy + requires fork(). Thanks to Irfan for pointing this out! + + * netsvcs/lib: Fixed a couple o' typos that had escaped detection + last night. Thanks to David Levine for reporting this. + + * ace/Synch[_T].h: removed the use of {} rather than ; for + the private copy constructors and assignment operators. + Hopefully this won't break code on older C++ compilers. Thanks + to Berni Merkle <merkle@io.freinet.de> for suggesting this. + + * Added a whole slew of minor fixes for unused variables in + the tests and examples. Thanks to Torbjorn Lindgren + <tl@funcom.no> for reporing these. + + * ace/Handle_Set.cpp (ACE_Handle_Set_Iterator): The order of + the clause + + this->handles_.mask_.fds_bits[this->index_] == 0 + && this->num_ < ACE_Handle_Set::MAXSIZE + + was backwards.

ACE_HAS_UNICODE signifies + that the OS has UNICODE support. It does not mean that your code + must be UNICODE. UNICODE must be defined at the project level. + +Wed Apr 16 16:55:47 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/SString.{h,cpp}: Modified CString to not allocate 1 byte for + a 0 length string.

Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/Strategies_T: Widened the constructor interface for + ACE_Process_Strategy based on the feedback I got from + implementing the Process_Strategy_Test.cpp program. + + * tests/Process_Strategy_Test.cpp: Added an interesting new test + that illustrates the use of the ACE_Process_Strategy and the + ACE_File_Lock. To exercise this program, you can telnet to it + and type "read" and "inc" to query and change the count of + the numbers in the file, respectively. + + * ace/Connector.cpp (create_AST): I fixed a couple of things + in Connector.cpp: + + - In create_AST, it needs to save and restore errno, else it + gets wiped on Win32 and other platforms. + + - On Win32 when a non-blocking connect completes and handle_output is + called, it tries to get the peer address. If done too quickly, it + fails. I put in a Sleep(0) call. I think this is not a great + solution, but I don't have a better one yet. + + Thanks to Steve Huston <shuston@riverace.com> for fixing + these bugs. + +Tue Apr 15 17:09:33 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/SOCK_Stream.cpp (close): Removed the call to close_writer() + on UNIX since that doesn't do the correct thing in many + cases since it causes a protocol transmission which isn't + what we want if we're using fork(). + + * ace/Strategies_T.cpp (activate_svc_handler): Added a call to + svc_handler->destroy() in the parent since we don't need it and + we're leaking descriptors and memory otherwise... Thanks to + Kevin Boyle <kboyle@sanwafp.com> for reporting this. + + * ace/OS.i (thr_sigsetmask): Replaced the use of + PTHREADS_1003_DOT_1C with ACE_HAS_PTHREAD_SIGMASK.

Thanks to Chuck Gehr + <gehr@sweng.stortek.com> for reporting this. + + * ace/Strategies_T: Added a new ACE_Connect_Strategy that + complements the ACE_Strategy_Connector in the same manner that + the ACE_Accept_Strategy complements the ACE_Strategy_Acceptor. + + * ace/Connector.h: The destructor for ACE_Connector should have + been virtual. Now it is. + + * ace/Connector: Added a new factory method called + make_svc_handler(). This behaves similiarly to the + ACE_Acceptor::make_svc_handler(). However, for the + ACE_Connector we only use this when the SVC_HANDLER * is NULL. + + * ace/Connector: Changed the signature for connect() to take a & + to a SVC_HANDLER * in anticipation of our new + ACE_Strategy_Connector. This new connector will make it easy to + implement cached connections. + + * ace/config-win32-common.h: Added a new #include for <mswsock.h>, + which contains the declarations for TransmitFile() data + structures.

This allows the Proactor + to easily support new asynchronous operations. + + Currently, the new Proactor supports minimal functionality. In + the future, we will complete this. + + The Proactor is used in conjunction with the new Asynch_IO + classes. There is a different class for each operation. Please + see Asynch_IO.h for details. + + There is also a new ACE_Asynch_Acceptor that uses AcceptEx. + + Example is in: + ACE_wrappers/examples/Reactor/Proactor/test_proactor.cpp. + + This example illustrates how the ACE_Proactor can be used to + implement an application that does various asynchronous + operations. + + * apps/JAWS/server: Complete rewrite of JAWS. The new JAWS has + support for Asynch-Thread-Pool (on WIN32), Synch-Thread-Pool, + and Thread-per-Request. Different models can be configured using + the svc.conf file. The server now supports both GET and PUT + commands. + + The HTTP_Handler class is a state based implementation of the + HTTP protocol. Therefore, it can be used synchronously and + asynchronously. It uses an abstract IO class to move between + different HTTP protocol states. It is up to the IO class to + decide on synchronous or asynchronous I/O. + + * apps/JAWS/client: This is an example of the implementation of + BlobStreaming in ACE. This version of BlobStreaming uses HTTP as + a transport protocol. + + Blobby :-) is a simple application written using the ACE_Blob + class, which is capable of doing both file uploads and + downloads. If a file is downloaded, the downloaded data is sent + to standard output, so that it can be piped as necessary. + + * ace/Mem_Map.cpp (map_it): This method now uses ACE_OS::pwrite + (if ACE_HAD_P_READ_WRITE is defined) instead of + ACE_OS::lseek/ACE_OS::write to write the end-of-file byte. The + old scheme does not work if the file is in OVERLAPPED mode. + + * ace/OS: Added pread and pwrite to the OS class (if + ACE_HAD_P_READ_WRITE is defined). On Win32, these functions use + the OVERLAPPED structure to specify the offset. This + implementation will block until the write/read completes (even + if the file is in OVERLAPPED mode). + + * ace/config: Added ACE_HAS_P_READ_WRITE to the following + platforms that support pread() and pwrite() calls: + config-sunos4-g++.h + config-sunos4-lucid3.2.h + config-sunos4-sun3.x.h + config-sunos4-sun4.1.4.h + config-sunos4-sun4.x-orbix.h + config-sunos4-sun4.x.h + config-sunos5.4-centerline-2.x.h + config-sunos5.4-g++.h + config-sunos5.4-sunc++-4.x-orbix.h + config-sunos5.4-sunc++-4.x.h + config-sunos5.5-g++.h + config-sunos5.5-sunc++-4.1.h + config-sunos5.5-sunc++-4.x-orbix.h + config-sunos5.5-sunc++-4.x.h + config-sunx86-sunc++-4.x.h + config-win32-common.h + +Sun Apr 6 14:16:18 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * tests/Timer_Queue_Test.cpp: Added tests to make sure that the + new ACE_Timer_Queue::cancel() logic is working correctly. So + far, it seems to be fine. + + * ace/Timer_{Heap,List}.cpp (cancel): Changed the comparison for + dont_call_handle_close to be correct. + + * ace/OS.cpp: Deleted a useless return. Thanks to Gonzalo + A.

Diethelm <gonzo@ing.puc.cl> for this. + + * ace/Process: Added new support for setting the environment + variable and the current working directory. Thanks to Gonzalo + A. Diethelm <gonzo@ing.puc.cl> for this enhancement. + + * ace/OS.h: "sys/stat.h" was being included more than once, so I + fixed this. Thanks to Gonzalo A. Diethelm <gonzo@ing.puc.cl> + for reporting this. + + * ace/XtReactor.cpp: Added the register_handler_i() method, which + just delegates to the one defined in the Reactor. This is + necessary to adjust to the C++ type system rules. Thanks to + Gonzalo A.

Thanks to Matthias Kerkhoff + <make@cs.tu-berlin.de> for insisting on this. + + * ace/OS.i (nanosleep): If the nanosleep() system call isn't + supported by the OS platform we'll just use ACE_OS::sleep(const + ACE_Time_Value &) instead. + + * ace/Log_Msg.cpp: Changed the logic of + ACE_Log_Msg_Manager::remove() so that it returns the number of + remaining registered instances. When this goes to 0 we'll + cleanup. + + * ace/OS.i: Enhanced the ACE_OS::cond_[timed_]wait() methods so + that they use SignalObjectAndWait() whenever possible to avoid + potential problems with unfairness.

Harrison <harrison@waltz.cs.wustl.edu> + + * ace/Signal.i (ACE_Sig_Guard): Changed the constructor of + ACE_Sig_Guard so that it doesn't call ACE_OS::sigprocmask for + Win32. This keeps errno from being set to ENOSYS at random + times. + +Sat Apr 05 17:27:02 1997 <irfan@TWOSTEP> + + * Registry.cpp (resolve): Type and size of the object is only set + if RegQueryValueEx() returns success.

Levine <levine@cs.wustl.edu> + + * ace/Log_Msg.cpp (instance): Added another ACE_NO_HEAP_CHECK. + Matthias provided the fix. + + * ace/config-win32.h: Disable ACE_HAS_STRICT by default, because + it will break existing application code. + + * ace/OS.{h,cpp},Log_Msg.{h,cpp}: fixes from Matthias Kerkhoff + <make@cs.tu-berlin.de> to avoid memory-leak reports when MFC + or (the CrtHeapXXX()-functions of the Win32 runtime library) + are used. + + The problem is, that MFC (and so may other Win32 applications + do) allocates a thread specific storage slot for each running + thread which contains various control and debug informations. + Part of this information is an object, which when constructed + makes a snapshop of the heap. When this object is destroyed, + the snapshot is compared to the actual heap. All object still + existing on the heap are reported as memory leaks (which + is in most situations correct). Because the object is deleted + when the thread (or programs main) is left and this happens + before atexit is called, some leak reports are false (because, + e.g., all these ACE_Log_Msg's will be deleted in atexit). + + The fix for ACE_Log_Msg consists of three changes (two only + relevant for Win32, one relevant for all platforms.) + Description of changes: + + a) Introduced a new macro ACE_NO_HEAP_CHECK, which turns + off the built in heap checking until the current code block + is left. (defined for all platforms, but only does something + for Win32). This changes os.h and config-win32-common.h. + + b) Added a static member function to ACE_Log_Msg. The function + (exists) returns 0 if the calling thread don't have an ACE_Log_Msg + and non-null if an ACE_Log_Msg exists. This changes Log_Msg.h + and Log_Msg.cpp. + + c) Changed ACE_Thread_Adapter in a way that creating a new + thread does not automatically create an ACE_Log_Msg for the + calling thread. This happened until now, because the new + thread inherited the log settings of the calling thread. + This behaviour makes no sense, if the calling thread does + not have an ACE_Log_Msg, so i use ACE_Log_Msg::exists() (see + above) to prevent the implicit creation of an ACE_Log_Msg + for the calling thread. + + Thanks, Matthias! + + * ace/config-win32.h and config-win32-common.h: new, consolidated + Win32 config files. Thanks, again, Matthias! + + * ace/OS.h (ACE_UNUSED_ARG): determine whether we're building + on an Irix platform by looking for ACE_HAS_IRIX_GETTIMEOFDAY + instead of ACE_HAS_IRIX62_THREADS. + + * ace/Log_Msg.cpp: VxWorks (only!) change: no longer strdups + program_name and local_host to avoid memory leaks. Instead, + the addresses of these are copied by ACE_Log_Msg. So, only + strings in the text segment should be passed to its functions! + Again, this change is for VxWorks only. + + * ace/Sched_Params.cpp: moved memsets of pcinfo so that entire + pcinfo structure is zeroed out, to _really_ avoid Purify warnings. + +Fri Apr 04 12:28:40 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/config-mvs.h: removed ACE_HAS_IP_MULTICAST because MVS + doesn't define ip_mreq.

Thanks to Ganesh + Ganesh Pai <gpai@voicetek.com> for solving this problem. + + * ace/Log_Msg.{h,cpp}: added ACE_Log_Msg destructor. In + instance (), added call to ::atexit () (::taskDeleteHookAdd () + on VxWorks) to register cleanup handler. Each new instance + of an ACE_Log_Msg is inserted into an ACE_Unbounded_Set; the + cleanup handler iterates over the Set and deletes the + ACE_Log_Msgs at program exit. + + Also, the two strings that are allocated get cleaned up after + the last ACE_Log_Msg instance is deleted. Many thanks to + Matthias Kerkhoff <make@cs.tu-berlin.de> for figuring this out + and cranking out the code. + + It works differently on VxWorks, because it doesn't have + ::atexit (). VxWorks has ::taskDeleteHookAdd (), which is + called when each task exits. So, the Set isn't used. Instead, + the cleanup hook is called for each task when it exits, passing + the task control block (TCB) of the exiting task. A pointer to + the ACE_Log_Msg instance is contained in one of the spare fields + of the TCB, so the cleanup handler simply deletes it. + + * ace/IOStream.h: specify template parameter (ACE_IOStream<STREAM>) + to ACE_OPERATOR{G,P}_SET macros.

Thanks to Paul Han + <phan@CCGATE.HAC.COM> for reporting this. + + * ace/Svc_Handler.cpp: Put the check (closing_ == 0) in the + destructor as well as in the destroy() method. This prevents a + possible core dump when the timer exists. The instruction + reactor::remove_handler in the shutdown method currently will be + called twice when ACE_Svc_Handler object is being deleted. Core + dump occurs when it tries to execute ACE_Reactor::remove_handler + method the second time because the ACE_Svc_Handler object + pointer has already been deleted by the previous instruction + ACE_Reactor::cancel_timer.

Levine <levine@cs.wustl.edu> + + * ace/High_Res_Timer.*: Changed scale factor to convert + platform-dependent clock units to microseconds instead of + nanoseconds. That way, it should be greater than 1 for + all supported platforms. So, it's now an unsigned long + instead of a double. + + * ace/OS.h: Changed ACE_hrtime_t to unsigned __int64 with + _MSC_VER.

Before HP-UX 10.10 it wasn't a problem because no library was + needed with ACE, but to support XLI the '-lxti' flag must be used + on binaries (but not on shared libs). + + * include/makeinclude/platform_hpux.GNU: + The PIC option (+Z) was used always, clearly not intended. + + * include/makeinclude/platform_hpux_gcc.GNU: + Added a config file for g++ under HP-UX. + + * include/makeinclude/platform_hpux_aCC.GNU: + Added a config file for HP/aCC compiler under HP-UX. + + * ace/Makefile: + * netsvcs/lib/Makefile: + Changed to support the SOEXT macro. + + * config-hpux-10.x.h: + * config-hpux-10.x-aCC.h: + * config-hpux-10.x-g++.h: + I updated the files to HP-UX 10.10, AFAIK since that version HP-UX + uses fd_set instead of int in select(2) (so ACE_SELECT_USES_INT is + not needed) and the OS supports siginfo_t and ucontext_t so + ACE_HAS_SIGINFO_T and ACE_HAS_UCONTEXT_T are defined. + I *do not* have threads at my site nor the infamous PHSS_6246 + patch so I couldn't test the threaded version nor the HP cfront + based one. + ACE compiled fine with g++ and HP/aCC though. + + * ace/OS.h: + * ace/Malloc_T.h: + HP/aCC supports the typename keyword. I added a new config macro + 'ACE_HAS_TYPENAME_KEYWORD', when it is defined ACE_TYPENAME + expands to 'typename' when not it expands to nothing. + On the cases where HP/aCC requires the usage of 'typename' I added + a 'ACE_TYPENAME'. + + * ace/OS.i: + * ace/OS.cpp: + ACE_OS::inet_aton cannot be inlined under HP-UX. + + * ace/Connector.h: + * ace/Connector.cpp: + I have decided to use a typedef (PEER_ADDR) instead of + ACE_PEER_CONNECTOR_ADDR, mainly because the second form + requires a ACE_TYPENAME before each usage. + + * ace/Event_Handler_T.i: + Much to my surprize ACE_TYPENAME is required when using a template + typedef as a return value. + + * ace/Local_Name_Space_T.h: + HP/aCC does not like the usage of a private typedef from another + class. + + * ace/Strategies_T.h: + * ace/Strategies_T.cpp: + ACE_Process_Strategy declared two defaults constructors: + ACE_Process_Strategy(void) and ACE_Process_Strategy(int = 1). + The constructor code was wrong, it called open() with parameters: + open(thr_mgr, thr_flags, n_threads) + none of which were defined, worse, open() receives just one + parameter (the number of processes) just as the constructor, I + believe that C-w programming is lurking here. + + * ace/Signal.cpp: + Though the header file does not declare ACE_Sig_Handlers under + HP-UX (and the code is not defined too) some auxiliary functions + that use ACE_Sig_Handlers were defined. I removed their + definition. + Some day I'll try to take a look at the code, trying to find out + was wrong with them. + + * ace/Stream_Modules.h: + * ace/Stream_Modules.cpp: + By mistake I commented out the ACE_ALLOC_HOOK_* macros; have to + fix it *real soon*. + + * ace/Task_T.cpp: + No need to include "ace/Module.h" since only the template + declaration is used. When ACE_TEMPLATES_REQUIRE_SOURCE is defined + you end up using ACE_Thru_Task before it gets defined. + This is no problem unless your compiler checks template sintax + before instantiation as the HP/aCC compiler do. + + * examples/Reactor/Misc/test_demuxing.cpp: + ACE_MT_SYNCH was used, but it is only defined if ACE_HAS_THREADS, + I used ACE_SYNCH instead, which is defined as ACE_MT_SYNCH if + ACE_HAS_THREADS and as ACE_NULL_SYNCH if not. + Maybe the semantics are wrong, but the thing compiles. + +Fri Mar 21 15:10:59 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/Makefile (FILES): Moved Log_Msg to the beginning of the + source list in the ace Makefile. This is nice because it forces + the compilation of OS.i and that, obviously, is where you get + the complaints for the port. It's nice to have it at the + beginning so you catch the errors very early on before you've + compiled 30 or 40 files. Thanks to Scott Halstead + <scott.halstead@gs.com> for this suggestion. + + * ace/Memory_Pool.cpp: Added #if !defined + (ACE_LACKS_SYSV_SHMEM) to handle systems like Chorus that + lack this feature. + +Thu Mar 20 18:58:50 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/Svc_Handler.cpp (destroy): Added a state variable to keep + track of when we are closing down the Svc_Handler.

Thanks + to Bert Craytor <Bert_Craytor@peoplesoft.com> for reporting + this. + + * tests/Conn_Test.cpp: Added a new test that makes sure the + Acceptor, Connector, and Svc_Handler are working correctly. + + * ace: Added some more changes for Chorus. Thanks to Wei Chiang + <chiang@tele.nokia.fi> for these changes. + + * ace/OS.h: Added #define for SIGSEGV for platforms that lack it + (e.g., Chorus). + + * ace: Made a bunch of minor changes to support SunOS 4.x better. + Thanks to Scott Halstead <scott.halstead@gs.com> for reporting + these problems. + + * tests/Conn_Test.cpp: Added ACE_TEMPLATES_REQUIRE_SPECIALIZATION + for the various templates used in this test.

Levine <levine@cs.wustl.edu> + + * ace/OS.{h,cpp},Makefile; also, renamed Scheduling_Params.* to + Sched_Params.* and removed Thread_Priority.*: + + Major change in scheduling parameters interface: + The key change is that there is no longer a special thread priority + enum. Thread_Priority was changed to int, so applications can do + whatever they want. The ACE_Sched_Params class has some static + functions to help do this portably. + + Here are the changes from the ACE 4.1.3: + + 1) ACE_Thread_Priority: removed this class. + + It contained "priority class" and "thread priority". + "Priority class" is platform-specific and doesn't + need to be visible in ACE; it is subsumed by scheduling policy, + see below. "Thread priority" is replaced by the global + ACE_Sched_Priority typedef in ace/OS.h, see next change. + + 2) ace/OS.h: added ACE_Sched_Priority typedef (to int) + and ACE_SCOPE_THREAD. + + 3) ace/OS.h: added scheduling policy #defines: ACE_SCHED_OTHER, + ACE_SCHED_FIFO, and ACE_SCHED_RR. There's an ACE_Sched_Params:: + Policy typedef that can take one of these values. + + 4) ACE_Sched_Params: added priority_min (), priority_max (), + next_priority (), and previous_priority () functions. All + require an ACE_Sched_Params::Policy argument and take an + optional scope argument (to support the distinct thread + and process priorities on DEC UNIX). + + min_priority () and max_priority () have platform-specific + and policy-specific values, and direction (the min value may + be higher than the max value). The increment and decrement + operations allow applications to iterate over them, etc., + without explicitly specifying the direction of the priority + (0 for high or low priority). + + 5) The only way to apply ACE_Sched_Params is through + ACE_OS::sched_params (const ACE_Sched_Params &). + (This is not really a change, except for the name change from + ACE_OS::set_sched_params (). + + It sets both policy and priority of current thread or + process (depending on the scope in ACE_Sched_Params). + Not all combinations of policy, priority, and scope are + legal on all platforms. Unfortunately, I see no way around + this, because the intersection of legal ranges + on our supported platforms is empty. If an illegal request + is made, ACE_OS::sched_params () sets errno to EINVAL and + returns -1. + + 6) added ACE_OS::thr_setprio (const ACE_Sched_Priority prio) + to set the current thread's priority, only. + + Many thanks to Thilo Kielmann <kielmann@informatik.uni-siegen.de> + for his careful review of this class design, thoughtful comments, + and assistance with implementation, especially for PTHREADS + platforms. + +Wed Mar 5 14:36:59 1997 Irfan Pyarali <irfan@flamenco.cs.wustl.edu> + + * SString.cpp: Fixed ACE*String initialization bugs.

This is + necessary to keep from starving out other Event_Handlers. + Thanks to Rod Skinner <rods@in.ot.com.au> for pointing out the + need for this. + + * ace/Reactor.cpp: Fixed a bug in the WIN32 + ACE_Reactor_Notify::handle_input() logic.

The new version allows multiple threads of + control to wait simultaneously in + ::WaitForMultipleObjects(). This was difficult because the + set of ACE_HANDLEs used in ReactorEx->handle_events() is + shared between all threads. We devised a clever protocol + that ensures all changes to the handle set are + serialized. This serialization was achieved by using + multiple (auto and manual) events and mutexes and by taking + advantage of the "waitAll" semantics of + WaitForMultipleObjects(). + + Concept of "owner" thread is introduced in ReactorEx. We + need to keep track of the "owner" because we don't want + multiple threads to try to expire timers. Therefore the + "owner" thread is the only one allowed to expire + timers. Also, the owner thread is the only thread which + waits on the internal notify handle (which is used to + dispatch explicit calls to + ACE_ReactorEx::notify(). Initially, the creator thread of + ReactorEx becomes the "owner" thread. Ownership can later be + transferred among threads, just as with the standard + ACE_Reactor. + + We also updated the Handler Repository since it now + keeps track of <handle, event_handler> tuples to be added + and deleted from the current handle set at the appropriate + time (i.e., when all threads are out of + WaitForMultipleObjects() and have completed all necessary + dispatching). The Handler_Repository implements the update + protocol that is used to serialize changes to its internal + state. + + Two slots were added to the <size> parameter in the + constructor and open methods of ReactorEx that will store + handles used for internal management. Therefore, users can add + upto MAXIMUM_WAIT_OBJECTS - 2 handles into ReactorEx. On + current WinNT platforms (e.g., 3.51 and 4.0) + MAXIMUM_WAIT_OBJECTS is 64. + + Note that the interface to ReactorEx did not change in this + process. Your existing code should work without changes. + Moreover, we've optimized the implementation so that if only + 1 thread calls ACE_ReactorEx::handle_events() the code is + very efficient. Moreover, you can dynamically add or remove + threads without having to register them with the ReactorEx. + + * examples/Reactor/ReactorEx/test_MT.cpp: This application tests + multiple threads simultaneously calling + ReactorEx->handle_events(). It also shows how different threads + can update the state of ReactorEx. + +Wed Feb 12 00:08:42 1997 Douglas C. Schmidt <schmidt@polka.cs.wustl.edu> + + * ace/Synch: Added a remove() call to ~ACE_Thread_Mutex so that it + will be removed (and resources cleaned up) automatically when an + ACE_Thread_Mutex object goes out of scope.

Levine <levine@cs.wustl.edu> + + * ace/config-sunos-sun*.h,README: added + ACE_LACKS_LINEBUFFERED_STREAMBUF and ACE_LACKS_SIGNED_CHAR. + + * ace/IOStream.{h,cpp}: support + ACE_LACKS_LINEBUFFERED_STREAMBUF and ACE_LACKS_SIGNED_CHAR + so that this builds with SunC++. + + * examples/IOStream/client/iostream_client.cpp: + reordered args and fixed argv indexes. + + * examples/IOStream/server/iostream_server.cpp: + use ACE_DEFAULT_SERVER_PORT for default port. + + * tests/Naming_Test.cpp (randomize): changed type of "size" arg to + size_t to avoid compiler warnings about signed/unsigned comparison. + +Thu Feb 06 09:40:47 1997 Chris Cleeland <cleeland@cs.wustl.edu> + + * ace/config-linux*.h: added typedef of timespec_t. + +Wed Feb 5 01:45:03 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/OS.i: Changed the Win32 implementation of all methods that call + WaitForMultipleObjects() so that errno is set to + WAIT_ABANDONED if the mutex is abandoned. This makes it + possible for users to understand why ACE_OS methods that use + synchronization operations fail. Thanks to Ivan Murphy + <Ivan.Murphy@med.siemens.de> for reporting this problem. + + * ace/IOStream.cpp (ACE_Streambuf): Moved the const initialization + from the header file to the constructor since this is the only + portable way to do this. Thanks to Michael Maxie + <maxie@acm.org> for reporting this. + + * ace/OS.i: Updated the call to thr_setprio() for pthreads so that + it first determines the existing scheduling parameters and then + updates the priority. Thanks to Thilo Kielmann + <kielmann@informatik.uni-siegen.de> for help with this. + + * ace/config-osf1-4.0*.h: Updated ACE_NEEDS_HUGE_THREAD_STACKSIZE + to be 1 mega to minimize porting surprises. Thanks to Thilo + Kielmann <kielmann@informatik.uni-siegen.de> for help with this. + + * tests/Naming_Test.cpp: Cleaned up a few minor things related to + int i = 0 vs. size_t i = 0. + + * ace/SOCK_Dgram.cpp: Added a new macro called + ACE_HAS_SOCKADDR_MSG_NAME, which is used on platforms (e.g., + DG/UX) that require a cast to (struct sockaddr *) for the + msg_name field of struct msghdr. + +Wed Feb 05 10:45:41 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/IOStream.h: replaced __*manip with expanded types, because + Sun C++ doesn't have those typedefs; and added complete prototypes + for send, recv, send_n, and recv_n. + + * ace/IOStream.cpp: fixed "#define ACE_IOSTREAM_C" to keep g++ sane. + + * ace/Hash_Map_Manager.{h,cpp},Map_Manager.{h,cpp}: replaced + DEFAULT_SIZE with ACE_DEFAULT_MAP_SIZE so that Naming_Test runs + on SunC++ 4.1. + + * ace/High_Res_Timer.*: added optional scale factor. + + * examples/IOStream/{client,server}/Makefile: addd -g++ if building + with gcc. + + * tests/Naming_Test.cpp: moved declaration of "i" out of for loop + because it is used after the loop. + + * examples/ASX/UPIPE_Event_server/{Consumer,Supplier}_Router.cpp + (open): return 1 if init () succeeds. There's a commented-out + call to activate the objects that would (should?) return a value. + + * examples/IPC_SAP/FIFO_SAP/FIFO-client.cpp (main): declare n + as ssize_t instead of size_t to avoid compiler warning about + signed/unsigned comparison. + +Tue Feb 4 19:06:52 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/Signal.cpp: Fixed all the ACE_Sig_Handler[s] methods so that + they now use ACE_Guard, rather than ACE_TSS_Guard, *unless* they + are actually performing callbacks to user-code. Not only is + this faster, but it also avoids thread-specific storage key + leaks on platforms like Solaris! + + * ace/OS.cpp (thr_keyfree): Added a new #ifdef for + ACE_HAS_THR_KEYDELETE, which is defined for UNIXWARE. This + fixes a nasty problem with leaking thread-specific keys. Thanks + to Nigel Owen <Nigel@voicelink.co.nz> for reporting this. + + * ace/Message_Block.cpp: Added a #include for + "ace/Service_Config.h". + + * ace/Malloc.i: Fixed a few warnings by removing the names of + unused parameters. + + * ace: Added many minor changes to ACE so that it will work on + DG/UX. Thanks to Michael Maxie <maxie@acm.org> for all these. + + * ace/LSOCK_Stream.cpp: Applied the same fix as to LSOCK.cpp. + + * ace/LSOCK.cpp: Removed the cast of 0 to (char *) for msg_name + since some platforms use (struct sockaddr *). By omitting the + cast the compiler will figure it out correctly. Thanks to + Michael Maxie <maxie@acm.org> for this. + + * ace/IOStream: Added a new template adapter for creating an + iostream-like object using an ACE IPC Stream for the actual I/O. + Thanks to James CE Johnson <jcej@lads.com> for this. + + * examples/Misc/test_iostreams.cpp: Added a test that illustrates + how the new ACE_iostreams mechanism works. Thanks to James CE + Johnson <jcej@lads.com> for this. + + * ace/Message_Block: Updated the ACE_Message_Block implementation + to use ACE_Service_Config::alloc() if the user doesn't supply a + customize version. This also means that we never delete the + allocator_strategy_, so we can remove this flag and reduce the + amount of storage by 4 bytes. Thanks to Irfan for noticing that + we can do this. + + * ace/platform_dgux4_epc.h: Added a new platform config file + for DG/UX. Thanks to Michael Maxie <maxie@acm.org> for + this. + + * ace/config-dgux-4.11-epc.h: Added a new config file for DG/UX. + Thanks to Michael Maxie <maxie@acm.org> for this. + +Tue Feb 04 18:26:01 1997 <irfan@cha-cha.cs.wustl.edu> + + * ace/Service_Config.cpp (alloc): The implementation now creates a + ACE_New_Allocator rather than a ACE_Allocator_Adaptor. If + you still want the old behavior, simply provide your own + custom allocator singleton for ACE_Service_Config. + + * ace/OS.i (mktemp): Added the missing ACE_INLINE directive. + + * ace/OS.h: ACE_HAS_INLINED_OSCALLS is now automatically defined + when __ACE_INLINE__ is defined. This avoids mysterious linking + problems that occur otherwise. + + * ace/Malloc: Added a virtual destructor to ACE_Allocator. Also + added a new class ACE_New_Allocator which is a sub-class of + ACE_Allocator. This class uses the new/delete operators to + allocate and free up memory. Please note that the only methods + that are supported are malloc() and free(). All other + methods are no-ops. If you require more functionality, please use: + ACE_Allocator_Adapter <ACE_Malloc <ACE_LOCAL_MEMORY_POOL, + MUTEX>> This will allow you to use the added functionality of + bind/find/etc. while using the new/delete operators. + +Mon Feb 3 15:35:24 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/config-aix-*.h: Added a (char *) cast to + ACE_DEFAULT_BASE_ADDR. Thanks to John Cosby + <John.D.Cosby@cpmx.saic.com> for reporting this. + + * ace/OS.cpp: Added a new set() method that sets the Time_Value + from a double. Thanks to Brad Flood for this suggestion. + + * ace/OS: Changed ACE_OS::flock_t to ACE_OS::ace_flock_t to avoid + a name clash on DG/UX.

Thanks to Marius for + reporting this. + + * ace: Added the new config-aix-4.2.x.h file, which supports the + AIX4.2 platform. Thanks to Rob Jordan <jordan@hursley.ibm.com> + for this. + + * include/makeinclude/platform_aix4.2.GNU: Added support for the + new AIX4.2 platform. Thanks to Rob Jordan + <jordan@hursley.ibm.com> for this. + + * ace/OS.h: It's now possible to override ACE_DEFAULT_BASE_ADDR in + a config.h file.

Thanks to Bob Olson + <olson@mcs.anl.gov> for this suggestion. + + * ace/OS.h: define hrtime_t as long long if ACE_HAS_AIX_HIRES_TIMER. + + * ace/OS.{i,cpp}: uninlined ACE_OS::gethostbyname (), + and ACE_OS::inet_ntoa () on VxWorks, because they have + static char arrays. + + * ace/OS.i (gethostbyaddr, getservbyname, gethostbyaddr, + gethostbyname, getservbyname_r): with ACE_HAS_NONCONST_GETBY, + instead of copying the const argument, just cast it to (char *). + Thanks to Michael Maxie <maxie@acm.org> for pointing out the + problem with the nonstatic char arrays with sizes determined at + runtime. + + * ace/High_Res_Timer.*: added ACE_HAS_AIX_HIRES_TIMER support. + Also, renamed get_time () to elapsed_microseconds (). + + * examples/Threads/{Timer.h,context_switch_time.cpp}: + ACE_High_Res_Timer::elapsed_microseconds () instead of + ACE_High_Res_Timer::get_time (). + + * bin/create_ace_build: added this script: it creates an ACE build + tree in directory "build/<build name>" below the current + directory, which must be a ACE "top level" directory (such as + $WRAPPER_ROOT). The build tree directory structure mirrors that + of the ACE top level directory structure, except that instead of + containing any plain files, it contains only symlinks to the files + in the ACE top level structure. + +Thu Jan 30 06:57:50 1997 David L.

Thanks to Luca + for this. + + * examples/Connection/misc/Connection_Handler.cpp: Added a + new example that illustrates how to use the Acceptor pattern + to create multiple threads, each running its own Reactor. + + * ace/Log_Msg.cpp (dump): Some of the variables in the dump() + method have the wrong format specification type. These are: + restart_ (%d), flags_ (%x), priority_mask_ (%d).

Thanks to David for + finding this. + + * ace/config-linux-lxpthreads.h: Added #defines for + ACE_HAS_AUTOMATIC_INIT_FINI and ACE_HAS_SVR4_DYNAMIC_LINKING. + Thanks to Marius for this. + + * ace/Malloc.h: Changed the typedef of ACE_Malloc_Align to a macro + called ACE_MALLOC_ALIGN to allow users to override this value in + their config.h file. This is necessary for platforms that don't + have "long" word alignments. Thanks to Fred LaBar + <flabar@fallschurch.esys.com> for this suggestion. + + * ace/OS.h: Added an #ifdef check for ACE_HAS_IRIX62_THREADS and + if so, we'll use the if (&a) /* null */; } form of the + ACE_UNUSED_ARG macro to avoid unnecessary warnings.

Thanks to John Morey for reporting this. + + * ace/Synch_T.h: Fixed: class ACE_Write_Guard: method: + tryacquire_write so that it will call + ...->lock_->tryacquire_write() and not + ...->lock_->acquire_write(). Thanks to Alexandre Karev + <Alexandre.Karev@cern.ch> for this fix. + +Thu Jan 16 15:51:16 1997 David L. Levine <levine@cs.wustl.edu> + + * Dump.cpp (register_object): initialized "slot" so that g++ doesn't + complain about uninitialized use. + + * Reactor.cpp (initialized): use ACE_GUARD_RETURN instead of + ACE_GUARD because the function returns a value; + (find): initialize "i" if handle is out of range so that g++ + doesn't complain about uninitialized use. + + * Service_Repository.cpp (remove): removed unused variable "handle". + + * Thread_Manager.h: made destructor virtual now that spawn_i () is + virtual. + + * Timer_Heap.cpp: changed some int loop indicies to size_t to + make sure that comparisons are consistently signed or unsigned. + + * OS.h, config-vxworks*.h: removed ACE_HAS_GREENHILLS_SOCKETS + ACE macro because the code it wrapped applies to all VxWorks + compilers, not just GreenHills. + +Wed Jan 15 02:06:21 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/ACE.cpp (round_to_pagesize): If _SC_PAGESIZE is enabled then + we set the ACE::pagesize_ variable using sysconf(2).

Thanks to John + Morey for reporting this. + + * ace/Reactor.cpp: Modified the close() method so that it can be + called multiple times with no bad side-effects. + + * ace/Pipe.cpp: Modified the close() method so that it can be + called multiple times with no bad side-effects. + + * ace/Reactor: Added an initialized() method that indicates + whether the Reactor was successfully initialized. Also + rearranged the code in ACE_Reactor::open() so that initialized_ + is only set at the end of the method when everything succeeds. + If things *don't* succeed, we call close() on the way out. + Thanks to Luca for these suggestions. + + * ace/Reactor.cpp (close): When closing down the ACE_Reactor, we + now set initialized_ back to 0 so that it can be reopened again + later. + + * tests/Reader_Writer_Test.cpp: There were some problems with this + test due to the fact that on many pthreads platforms pthread_t + isn't an int (it's a struct). Thanks to Chuck Gehr + <gehr@sweng.stortek.com> for the fix. + + * ace/OS.i (exit): In WIN32 when the process exits through an + ExitProcess() call, some process resources (e.g., file handles) + are freed before the static variable destructors are + called. This results in an application error when tracing is + enabled. Removing the ACE_TRACE call in ~ACE_Event_Handler + seems to fix this. Thanks to Luca for this fix. + + * ace/OS: Fixed the implementation of semaphores for the POSIX + port (POSIX lacks semaphores). The trick was to add a "waiters" + field, along with the semaphore count. Thanks to John Bossom + <John.Bossom@Cognos.COM> for reporting this. + + * examples/Threads/wfmo.cpp: Added a new test program that seems + to indicate that the Win32 WaitForMultipleObjects() function can + be called in multiple threads, all of which wait on the same set + of HANDLEs. Note that the dispatching of the threads is + relatively "fair" (i.e., everyone gets a chance to process the + various HANDLEs as they become active). Thanks to Ari Erev + <Ari_Erev@comverse.com> for suggesting this and providing the + initial code. + + * ace/Thread_Manager.h: Made the spawn_i() method virtual and + moved it into the protected section of the class so that it can + be over-ridden by subclasses. Thanks to Tim Harrison for + suggesting this. + +Tue Jan 14 15:57:55 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/OS.h: Changed the default size of ACE_DEFAULT_TIMERS to + _SC_TIMER_MAX (which is typically around 40 or so). + Thanks to Stuart Powell <stuartp@in.ot.com.au> for + suggesting this. + + * tests/Timer_Queue_Test.cpp (main): Added some additional logic + so that we can test the performance of the preallocated and + non-preallocated ACE_Timer_Heap. + + * ace/Timer_Heap: Added a new "preallocate nodes" mechanism to the + ACE_Timer_Heap. If this is enabled by the constructor, then we + preallocate as many ACE_Timer_Nodes as there are slots in the + heap. This allows us to completely remove the need for dynamic + memory allocation, which is important for real-time systems. + + * ace/Thread_Manager.cpp (remove_thr): Optimized the code just a + tad by decrementing the current_count_ *first*. Thanks to Per + Andersson <Per.Andersson@hfera.ericsson.se> for suggesting this. + + * ace/ReactorEx: Updated the implementation so that the + handle_events() method now in fact *does* return the number of + event handler's dispatched (i.e., the implementation matches the + documentation...). Thanks to Hamutal Yanay + <Hamutal_Yanay@mail.icomverse.com> for reporting this. + + * ace/Service_Repository.cpp (remove): Removed an extra call to + ACE_OS::dlclose(). This is already being called in the + destructor of ACE_Service_Record. Thanks to Karlheinz for + reporting this. + + * man: Updated all the nroff and html documentation. + + * ace/Timer_Heap: Implemented the spiffy new timer cancellation + algorithm that requires only O(log N) time to remove a timer + from the ACE_Timer_Heap. This is about 50 to 100 times faster + than using the ACE_Timer_List implementation. + +Tue Jan 14 21:01:36 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/OS.h: Replace "Linux" preprocessor symbol with "linux". + +Mon Jan 13 17:57:50 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/Synch: Added lock() accessor methods to both + ACE_Process_Semaphore and ACE_Process_Mutex.

Levine <levine@cs.wustl.edu> + + * ace/OS.h: Added #undefs of sigemptyset and sigfillset on Linux + when __OPTIMIZE__ is enabled. Yes, the system header on Linux + really #defines them when optimizing! Thanks to an anonymous + ACE user for pointing this out. + + * tests/tests_config.h: Dropped ACE_MAX_ITERATIONS back to 10. + +Sun Jan 12 16:59:52 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/Timer_List.cpp (schedule): Cleanup the code so that (1) + timer_id never == -1 (in order to distinguish it from error + return values and (2) so that we avoid an unnecessary check for + operator new failure. + + * ace/OS.h: Added a new #define called ACE_DEFAULT_MAX_TIMERS, + which specifies the maximum number of ACE_Event_Handlers + supported by ACE_Timer_Heap. + + * ace/Proactor.cpp (ACE_Proactor): Updated the allocation of + ACE_Timer_Queue so that it really points to an ACE_Timer_List by + default. Naturally, this can be overridden by users. + + * ace/ReactorEx.cpp (open): Updated the allocation of + ACE_Timer_Queue so that it really points to an ACE_Timer_List by + default. Naturally, this can be overridden by users. + + * ace/Reactor.cpp (open): Updated the allocation of + ACE_Timer_Queue so that it really points to an ACE_Timer_List by + default. Naturally, this can be overridden by users. + + * ace: Added two new classes called ACE_Timer_List and + ACE_Timer_Heap, which derive from ACE_Timer_Queue. + ACE_Timer_List is essentially the old behavior of + ACE_Timer_Queue, i.e., it uses an implementation of a linked + list of ACE_Timer_Nodes. ACE_Timer_Heap, on the other hand, + uses a heap-based callout queue, which is more appropriate for + certain real-time applications. + + * ace/Timer_Queue: Revised the ACE_Timer_Queue implementation so + that it's now an abstract base class with most of the + implementation details pushed into the ACE_Timer_List and + ACE_Timer_Heap subclasses. + + * ace/Timer_Queue.h: Made all the ACE_Timer_Queue methods public + so that we can override them in a subclass (e.g., the new + ACE_Timer_Heap). + + * examples/Logger/Acceptor-server/server_loggerd.cpp: Fixed this + example application so that it only uses a single Reactor (the + REACTOR::instance()) rather than two Reactors. Thanks to Sandro + Doro <alex@aureus.sublink.org> for reporting this. + + * netsvcs/lib/Logging_Strategy.cpp: Fixed the #include of + fstream.h and iostream.h to use the '<' '>' notation rather than + the '"' and '"' notation. This avoids problems with running + "make depend". Thanks to Rino Simioni <sir@necsy.it> for + reporting this fix. + +Sun Jan 12 18:20:49 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/ACE.cpp (round_to_pagesize): fixed typo in reference to + ACE::pagesize_. + + * ace/ACE.cpp: initialize ACE::pagesize_ to 0. + + * ace/config-irix*.h and config-win*.h: removed ACE_PAGE_SIZE + definition because these platforms no longer use it. + + * tests/UNIX*.conf and Win32server.conf: replaced net_svcs + with netsvcs. + +Sat Jan 11 15:11:28 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * ace/OS.i (thr_setprio): The POSIX implementation of + ACE_OS:thr_setprio did not set the priority. It calls: + + pthread_setschedparam( thr_id, &policy, ¶m ) + + and then does + + prio = param.sched_priority. + + instead of + + param.sched_priority = prio; + + This is now fixed. Thanks to John Bossom <John.Bossom@Cognos.COM> + for reporting this. + + * ace/config-irix*.h: Modified all the IRIX config files to + use the new ACE_HAS_GETPAGESIZE feature since this is necessary + to differentiate between IRIX and IRIX64. + Thanks to Fred LaBar <flabar@fallschurch.esys.com> for + reporting this. + + * ace/ACE.cpp: Modified the round_to_pagesize() so that if + a config.h file enables ACE_HAS_GETPAGESIZE then we use + that function in preference to the value in config.h. + Thanks to Fred LaBar <flabar@fallschurch.esys.com> for + suggesting this. + + * ace/ACE.cpp: Modified the round_to_pagesize() so that on + platforms that allow the page size to be obtained dynamically + we'll get that rather than replying on what it set in the + config.h file. We'll cache this value in a static variable + to speedup searches. Thanks to James Mansion for suggesting + this. + + * apps/Gateway/Gateway: Finished adding support for thread-safe + reference counting to the uses of ACE_Message_Block. + + * examples/ASX/Event_Server/Event_Server/Peer_Router.cpp: Replaced + the use of ACE_MT_SYNCH with ACE_SYNCH so that this will compile + correctly on non-MT platforms. + +Fri Jan 10 12:38:42 1997 Douglas C. Schmidt <schmidt@flamenco.cs.wustl.edu> + + * Added a COPYING file that explicitly states the copyright status + of ACE. + + * ace/config-win32-msvc4.x.h and ace/config-winnt-4.0-msvc4.x.h: + By default, we'll revert to *not* enabling + ACE_HAS_TEMPLATE_TYPEDEFS for MSVC++ 4.2, even though this is + well-support by the compiler since it breaks some application + code that expects to use 3 template parameters for + ACE_Svc_Handler<>. The "fix" is to use the ACE_SOCK_STREAM + macros (rather than using the "ACE_SOCK_Stream, ACE_INET_Addr" + tuple) in order to achieve portability in either case. Thanks + to Karlheinz for pointing out the need for backwards + compatibility. + +Wed Jan 8 01:00:05 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * tests/Message_Block_Test.cpp: Enhanced the torture test of the + ACE_Message_Block so that it stresses the reference counting + implementation in a multi-threaded environment. + +Wed Jan 08 10:26:45 1997 David L. Levine <levine@cs.wustl.edu> + + * ace/Message_Block.cpp (~ACE_Data_Block): assigned 0 to + allocator_strategry_ after deleting it; fixed template + specializations (for g++) by using macros instead of class names; + commented out template specializations because Service_Record.cpp + already has them, and they should only appear once in the library + in order to avoid link clashes + + * ace/Service_Object.cpp (ACE_Service_Object): reordered + initializations in constructor + + * ace/Service_Record.cpp (ACE_Service_Record): reordered + initializations in constructor + + * ace/config-linux-lxpthreads.h: added + ACE_HAS_RECURSIVE_THR_EXIT_SEMANTICS, thanks to + James CE Johnson <jcej@lads.com> for tracking down this + problem and testing the fix. + +Tue Jan 7 13:03:25 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/Message_Block: Continued to improve the + ACE_Message_Block/ACE_Data_Block implementation. + + * ace/Message_Block: Added a new constructor to ACE_Message_Block + that takes an ACE_Data_Block * and "owns" it. Thanks to Tim for + this idea. + + * ace/Log_Msg.cpp: Now that we've prevented signal handlers from + occurring within critical sections of ACE_Log_Msg::log() we + don't need to use the ACE_Recursive_Thread_Mutex anymore. + Instead, we just need ACE_Thread_Mutex. + + * ace/Log_Msg.cpp (log): Added an ACE_Sig_Guard to the block in + ACE_Log_Msg::log() that acquires the mutex that serializes + output. This prevents nasty problems with recursive to + ACE_Log_Msg::log() from within signal handlers. + + * ace/Service_Config.cpp (end_reactor_event_loop): Added a timeout + of ACE_Time_Value::zero to the ACE_Reactor::notify() method when + called in the ACE_Service_Config::end_reactor_event_loop(). + This prevents the Reactor from blocking indefinitely if there's + no longer a thread to receive from the notification pipe. + + * netsvcs/clients/Naming/Dump_Restore: Removed the vestigal + nametest.cpp and nametest.h files. I'm not sure why they were + still there, but they shouldn't have been! + + * ace/Synch.i (remove): this->owner_ should be set to -1 before + calling this->release(). Thanks to Per Andersson + <Per.Andersson@hfera.ericsson.se> for suggesting this. + + * ace/Thread_Manager.cpp (exit): Added a flag called "do_thr_exit" + to the ACE_Thread_Control::exit() method. This controls whether + we call ACE_OS::thr_exit() after removing the thread from the + Thread Manager's internal table. This is necessary to work + around pthread bugs on certain platforms (e.g., AIX and Linux). + + * ace/Synch.h: Removed the + ACE_Recursive_Thread_Mutex::set_nesting() method since this + isn't being used and is potentially dangerous. Thanks to Per + Andersson <Per.Andersson@hfera.ericsson.se> for suggesting this. + + * ace/XtReactor: Updated the XtReactor so that it uses the next + internal Reactor implementation. Thanks to Mark Rabotnikov + <mark@usp.elscintcorp.co.il> for reporting this. + + * ace/Task.i: Updated the grp_id(int) method to cache the group id + in the task and then set it in the Thread_Manager, if there is + one. Thanks to Hamutal Yanay <Hamutal_Yanay@mail.icomverse.com> + for suggesting this. + + * ace/Log_Record.h: Updated the ACE_Log_Record class to use the + new ACE_MAXLOGMSGLEN macro. + + * ace/OS.h: Added a new #define called ACE_MAXLOGMSGLEN. By + default this is 4k. However, you can reset it in the config.h + file if you'd like to increase or decrease the size. Thanks to + Anthony McConnell for suggesting this. + + * examples/Threads/tss[12].cpp: Tidied up the tss1.cpp and + tss2.cpp examples and improved the comments. Thanks to Luca for + suggesting this. + + * ace/Service_Object.cpp (fini): Added the "virtual" keyword to + the new destructor of ACE_Service_Type. Thanks to David for + reporting this. + + * ace/Message_Block.i: Rearranged the order of the ACE_Data_Block + and ACE_Message_Block locking_strategy() methods so that they'd + be defined as inline before being used. Thanks to David for + reporting this. + +Mon Jan 6 16:46:06 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/Service_Manager.cpp (fini): Only try to remove the + ACE_Service_Manager from the Reactor if it's actually been + registered in the first place (i.e., if it's get_handle() method + does not return ACE_INVALID_HANDLE). + + * netsvcs/servers/svc.conf: Changed the name of the net services + .so file from libnet_svcs to netsvcs so that it will work + correctly with our new "cross-platform" svc.conf ACE::ldfind() + strategy. Thanks to Marius Kjeldahl <marius@funcom.com> for + reporting this. + + * ace/Reactor.cpp (find): Added a strategic break and a check for + handle_in_range(). Thanks to Tim for this help! + + * netsvcs/clients/Naming/Client/svc.conf: Removed the "lib" part + from the executable shared object file names in the svc.conf + file so that it will work with the new "cross-platform" svc.conf + ACE::ldfind() strategy. Thanks to Marius Kjeldahl + <marius@funcom.com> for reporting this. + + * ace/Service_Record.cpp (fini): Added an extra assignment to a + temporary const void *obj to avoid problems with MSVC++ and it's + cast mechanism. + + * ace/ReactorEx.h: Added a default parameter to + ACE_ReactorEx::notify(). Thanks to Tim for noticing this. + +Sun Jan 5 10:48:23 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * tests: Added a new test for ACE_Message_Block, which is called + Message_Block_Test.cpp (no surprise there ;-)). This test + exercises the reference counting mechanisms. + + * ace/Message_Block.h: Made the destructors for ACE_Message_Block + and ACE_Data_Block virtual, so that these classes can be + subclassed and ACE_Message_Blocks can delete these + subclasses (either via release() or delete). Thanks to Tilo + Christ for suggesting this. + + * ace/Message_Block.cpp: Modified the implementation + of ACE_Message_Block/ACE_Data_Block so that we always create + an allocator_strategy_. By default, this strategy will be + ACE_Allocator_Adapter <ACE_Malloc <ACE_Local_Memory_Pool, ACE_Null_Mutex> >; + This greatly simplifies the code. + + * ace/Message_Block.h: It's now possible to assign a + Message_Block's priority when you create it. + + * ace/Reactor: Sped things up some more by merging the Reactor's + any_ready() and fill_in_ready() methods together. This reduces + redundant computations. + + * ace/Reactor: Changed the name of ACE_Reactor::detach() to + ACE_Reactor::remove_handler_i() and changed the name of + ACE_Reactor::attach() to ACE_Reactor::register_handler_i(). + This is more consistent with the other naming schemes. + + * ace/Reactor.cpp: Reworked the implementation of the Handler + Repository's unbind() method in order to simplfy the logic. + Also merged in all the Reactor's detach() functionality into the + unbind() method in order to localize all the handler removal + processing. + + * ace/Reactor[Ex].cpp: Added more descriptive errno entries for + failed operations in the handler repository. + + * ace/Reactor.cpp: Modified the implementation of the Handler + Repository's bind() method so that it reports an error if you + try to register an Event_Handler for an invalid HANDLE. + + * ace/Reactor.cpp: Reimplemented the internals of the Reactor to + prepare for the upcoming merge of the Reactor and ReactorEx to + use a single code base. + + * ace/Timer_Queue.cpp: Modified the behavior of the expire() + methods so that they return the number of ACE_Event_Handlers + whose handle_timeout() method was called. + +Sat Jan 4 11:47:05 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/Reactor.h: Removed the #ifdefs for ACE_HAS_POLL. This will + be recast as a strategy in subsequent implementations. + + * ace/Reactor.cpp: Added a new call, + ACE_Handler_Repository::handle_in_range(), which checks to make + sure that the HANDLE is within the range of 0 .. max_handlep1_. + This factors out some redundant code. + + * ace/Reactor.cpp: Sped up the performance of the Reactor by + removing redundant calls to + ACE_Handler_Repository::invalid_handle() and + ACE_Handler_Repository::find(). + + * tests/Reactors_Test.cpp: Added a test for + the new Reactor::notify() method with timeouts. + + * examples/Reactor/Misc/notification.cpp (svc): Added a test for + the new Reactor::notify() method with timeouts. + + * ace/Reactor[Ex]: Modified the Reactor and ReactorEx so that they + use timed send() operations for their notify() methods. This + makes it possible for users to bound the amount of time they're + willing to wait to try and notify the Reactor. This is mostly + useful to avoid infinite blocking if there is congestion in the + Reactor's notification mechanism. + + * ace/ACE.cpp: Added a new timed send() method that uses the + write() system call on UNIX and the socket send() call on Win32. + This new method is used in the new ACE_Reactor::notify() method, + which now supported timed notifications. + + * ace/Reactor.cpp (ACE_Handler_Repository): To simplify the code + and reduce unnecessary #ifdefs, I've merged the max_handlep1_ + and cur_size_ fields (which are now called max_handlep1_). + +Fri Jan 3 10:47:15 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace: Replaced all uses of "delete mb" with mb->release (); + + * ace/Stream_Modules.cpp: Replaced the use of explicit bit + twiddling with the ACE_BIT* macros. + + * ace/Message_Block.cpp: Make sure that we use the + allocator_strategy_ to create the memory for the reference count + since this may need to go into shared memory if that's the + memory pool where the Message_Block allocations are coming from. + + * ace/OS.h: Added two new macros, ACE_ALLOCATOR_RETURN and + ACE_ALLOCATOR, which are similar to ACE_NEW_RETURN and ACE_NEW, + except that these + + * ace/Message_Block.cpp (release): Make sure to "delete this" + outside the scope of the locking_strategy_. + + * ace/Service_Object.cpp: Added a destructor to ACE_Service_Type. + Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for + suggesting this. + + * ace/Service_Object.i: Be smarter about how we reassign the name_ + pointer, i.e., delete the old one and make a copy. Thanks to + Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting + this. + + * ace/Module.cpp (open): Rearranged the assignments to + reader_q->mod_ and writer_q->mod_ so that we don't try to + initialize through NULL pointers. Thanks to + Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting + this. + + * ace/Service_Record.cpp (ACE_Service_Record): Initialized name_ + to NULL so that the following change works correctly now. + Thanks to Per.Andersson@hfera.ericsson.se (Per Andersson) for + reporting this. + + * ace/Service_Record.i (name): Make sure to delete [] (char *) + this->name_ before allocating a new one. Thanks to + Per.Andersson@hfera.ericsson.se (Per Andersson) for reporting + this. + + * ace/Message_Block: Reworked the reference counting implemention + so that reference counts are shared correctly amongst their + various owners. This requires making a deep copy the "header" + portion, but a shallow copy of the "data." + + * ace/Message_Block.cpp (ACE_Message_Block): Updated all three + ACE_Message_Block constructors so that they all call the init() + method. This centralizes all the initialization logic in one + place. + +Thu Jan 2 00:42:21 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/Message_Block.cpp (ACE_Message_Block): Make sure to set the + cont_ field to 0 after "releasing" it so that we don't + mistakenly think it's still around later on. This problem arose + in the ACE_Message_Queue::close() method, which was trying to + count the number of bytes being freed. + + * ace/Message_Queue.cpp (close): Fixed a subtle bug where we + weren't actually deleting messages from the + ACE_Message_Queue::close() routine. This should work now... + + * ace/Message_Queue.cpp (close): Replaced the use of "delete mb" + with "mb->release()" since the Message_Blocks are now reference + counted. + + * ace/Message_Block: Enhanced the reference counting scheme so + that you can increment and decrement the count by an arbitrary + amount. This is particular useful when you know you'll be + sending the same Message_Block to N consumers. + + * ace/Singleton: The dump() must be used same as instance() + (without supplying an object) so it must be declarated *static*, + i.e., + + static void dump (void); + + Thanks to Sandro Doro <alex@aureus.sublink.org> for reporting + this. + + * examples/ASX/Event_Server: Completely rewrote and retested the + ACE Event Server example. The new code is *much* easier to + understand, has many more comments, is more robust, and compiles + much faster since I removed many of the templates. + + * examples/ASX/Event_Server/Tranceiver/tranceiver.cpp: Fixed the + tranceiver so that it shuts down correctly when the Event_Server + exits. + + * examples/Connection/non_blocking/CPP-connector.cpp: Fixed a + problem where we were trying to select() on ACE_STDIN on Win32. + Naturally, this doesn't work, so we used the + ACE::register_stdin_handler() to fix this. Thanks to + Samuel_Bercovici <Samuel_Bercovici_at_EFT__AD2@mail.icomverse.com> + for reporting this. + + * examples/ASX/Event_Server/Event_Server/Options: Changed the + Options class to be a Singleton... + + * ace/Task.h: Added "const" method qualifier to accessor methods + like is_reader() and is_writer(). + +Wed Jan 1 00:10:47 1997 Douglas C. Schmidt <schmidt@tango.cs.wustl.edu> + + * ace/Message_Block: Added a new static release() method that + behaves like the non-static method release(), except that it + checks if <mb> is 0. This is similar to CORBA::release(), which + is useful if you want to eliminate lots of checks for NULL + pointers before calling release() on them. + + * Updated all places in ACE where we use + ACE_Event_Handler::READ_MASK when we should be using + ACE_Event_Handler::ACCEPT_MASK. + + * examples/Service_Configurator/IPC-tests/server/Handle_Thr_Stream.cpp: + Changed the name of the acceptor class from Handle_Thr_Stream to + Handle_Thr_Acceptor, which is more accurate. + + * ace/Reactor: Since we've now got an + ACE_Event_Handler::ACCEPT_MASK (intended primarily to accept + connections asynchronously using Win32 overlapped I/O) we can + now use this with the ACE_Reactor, as well. In particular, any + time that we are registering a "passive-mode" socket acceptor we + can now specify ACE_Event_Handler::ACCEPT_MASK. This is much + more intuitive than using the READ_MASK (which never made any + sense...). The ACE_Reactor now treats the ACCEPT_MASK as a + READ_MASK internally, so you can still use READ_MASK if you'd + like (i.e., this change doesn't break any existing code). + + * ace/Event_Handler: Changed "get_priority" and "set_priority" to + simply "priority(void)" and "priority(int)" to be more + consistent with other parts of ACE. + + * apps/Gateway/Gateway: Updated the Gateway so that the + concurrency strategies can now be specified on the + command-line (or in the svc.conf file), rather than being + determined at compile-time. This is much more flexible. + See the ./apps/Gateway/Gateway/README file for details. + + * apps/Gateway/Gateway: Verified that all the multi-threading + strategies still work. + + * ace/Message_Block.cpp (ACE_Message_Block): Make sure that we + "release" the continuation field, rather than delete it, since + its reference count may be > 1. + + * ace/Log_Msg.cpp (log): Change the abort_prog logic a bit so that + we always print a message to stderr if we're exiting, + regardless... Thanks to David Levine for pointing this out. + + * apps/Gateway/Gateway: Moved all of the configuration file + parsing logic *outside* of the Event_Channel into the Gateway + class so that we wouldn't have unnecessary dependencies. + + * apps/Gateway/Gateway: Redesigned the Gateway so that the + Proxy_Handlers (i.e., the Consumer_Proxy and Supplier_Proxy) + most of their work to the Event_Channel. This "lightweight + proxy" design is an improvement since it is now possible to + emulate the COS Event Channel semantics within the Event_Channel + "kernel." + + * Happy new year! Let's start a new ChangeLog to celebrate the + new year. |
