1 PLANNED MAJOR CHANGES "SOMETIME IN THE FUTURE" (i.e., exact beta not known)
2 ===========================================================================
4 . RPM packaging as part of the release process by the doc_group (Remedy and user community)
6 . Remove BCB6, BCB2006, and the borland MPC template after the release of x.6.6
8 USER VISIBLE CHANGES BETWEEN ACE-5.6.5 and ACE-5.6.6
9 ====================================================
11 . Added an option to the ACE_Process_Options class to use a wchar_t
12 environment buffer on Windows.
14 . A new configure option, --enable-rcsid, was added to the autoconf build.
15 This is used to embed RCS IDs in object files.
17 . A new method was added: void ACE_Time_Value::msec (ACE_UINT64&)
18 This method, like the existing msec(ACE_UINT64&)const method, obtains the
19 time value in milliseconds and stores it in the passed ACE_UINT64 object.
20 This method was added so that msec(ACE_UINT64&) can be called on both
21 const and non-const ACE_Time_Value objects without triggering compile errors.
24 . Added ACE_Stack_Trace class to allow users to obtain a stack trace
25 within their application on supported platforms. A new conversion
26 character, the question mark, was added to ACE_Log_Msg for stack
29 . Added iterator support to ACE_Message_Queue_Ex class. The resulted in
30 the addition of ACE_Message_Queue_Ex_Iterator class and
31 ACE_Message_Queue_Ex_Reverse_Iterator class.
33 . Renamed gperf to ace_gperf to prevent clashes with the regular gperf
34 tool that is available in linux distributions
36 . Added support for FC9
38 . Added support for OpenSuSE 11.0
40 . Improved support for GCC 4.2 and 4.3
42 . Added support for CodeGear C++ Builder 2009
44 USER VISIBLE CHANGES BETWEEN ACE-5.6.4 and ACE-5.6.5
45 ====================================================
47 . Added new Monitoring lib that can be used to store and retrieve
48 counters. This is disabled by default because it is not 100%
49 finished yet, with the next release it will be enabled by default
51 . Fixed bug in ACE_Service_Config when it was used from a thread
54 . Add VxWorks 6.x kernel mode with shared library support to ACE
56 . Extended the implementation of Unbounded_Set, which has been
57 renamed Unbounded_Set_Ex, to accept a second parameter which is
58 a comparator that implements operator() which returns true if
59 the items are equivalent. Unbounded_Set has been reimplemented
60 in terms of Unbounded_Set_Ex using a comparator that uses operator==,
61 which captures the previous behavior.
63 . Added support for Intel C++ on MacOSX
65 USER VISIBLE CHANGES BETWEEN ACE-5.6.3 and ACE-5.6.4
66 ====================================================
68 . Reworked the relationship between ACE_Service_Config and
71 . Improved autoconf support
73 . Improved AIX with gcc support
75 . Improved OpenVMS support
77 . Improved VxWorks support
79 USER VISIBLE CHANGES BETWEEN ACE-5.6.2 and ACE-5.6.3
80 ====================================================
82 . Deprecated Visual Age 5 and older
84 . Closed a rare race condition hole whereby ACE_Atomic_Op<> function
85 pointers would not be fully initialized prior to use. See bugzilla
88 . Tweaks to support MacOS X Leopard (10.5 and 10.5.1) on Intel
90 . Fixed compile problems with MinGW with GCC 4.2. Do note that we do see
91 much more test failures then when using GCC 3.4.
93 . Changed to use synchronous exception handling with msvc 8/9 which is the
94 default. Asynchrous exception handling does catch access violations but
95 it leads to lower performance and other problems. See also bugzilla 3169
97 . Make ace_main extern C with VxWorks so that it doesn't get mangled
99 . Fixed compile errors and warnings for VxWorks 6.6
101 . Added an MPC generator for the WindRiver Workbench 2.6 which is shipped
104 . Added support for CodeGear C++ Builder 2007 with December 2007 update
107 . Added support for VxWorks 5.5.1
109 . Implemented the const reverse iterator for ACE_Hash_Map_Manager_Ex
111 . Increased support for using ACE_Hash_Map_Manager_Ex with STL <algorithm>
112 functions based on latest standard C++ draft
114 USER VISIBLE CHANGES BETWEEN ACE-5.6.1 and ACE-5.6.2
115 ====================================================
117 . ACE-ified the UUID class, which will change user applications slightly.
119 . Added support for Sun Studio 12
121 . Added support for Intel C++ 10.1
123 . Fixed runtime problems with VxWorks 6.x in kernel mode, several improvements
124 have been made to ACE, but also some problems in the VxWorks kernel have
125 been found for which WindRiver has made patches.
127 . Added support for VxWorks 6.5 kernel mode
129 . Added support for MacOS 10.5
131 . Support for MacOS 10.4 is now deprecated.
133 . Added support for OpenSuSE 10.3
135 . Added support for RedHat 5.1
137 . Added support for Microsoft Visual Studio 2008
139 . Added support for Fedora Core 8
141 . Added support for Ubuntu 7.10
143 . With Ubuntu 7.04 and 7.10 we can't use visibility, that results in
144 unresolved externals when building some tests. With lsb_release we
145 now detect Ubuntu 7.04 and 7.10 automatically and then we disable
148 . Removed deprecated (un)subscribe methods from ACE_SOCK_Dgram_Mcast
150 . Added an additional replace() method to ACE_OuptutCDR for replacing a
151 ACE_CDR::Short value. Also added write_long_placeholder() and
152 write_short_placeholder() to properly align the stream's write pointer,
153 write a placeholder value and return the placeholder's pointer. The pointer
154 can later be used in a call to replace() to replace the placeholder with a
157 . Initial support for VxWorks 6.6
159 . Removed support for pthread draft 4, 6, & 7. This makes the ACE threading
162 . Improved autoconf support
164 . Fixed TSS emulation problems
166 . Changed ACE_thread_t and ACE_hthread_t to int for VxWorks kernel mode. All
167 thread creation methods do have an additional const char* argument to
168 specify the task name, this now also works with pthread support enabled
170 . Use bool in much more interfaces where this is possible
172 . Added support for Debian Etch
174 . Fixed ACE CDR LongDouble support on VxWorks 6.x
176 . Added Microsoft Visual Studio 2008 project files to the release packages
178 . Fixed a few bugs in the ACE_Vector template
180 USER VISIBLE CHANGES BETWEEN ACE-5.6 and ACE-5.6.1
181 ====================================================
183 . Added support for CodeGear RAD Studio 2007
185 . Added support for CodeGear C++ Builder 2007 Update 3
187 . Modified the definiton of ACE_DEFAULT_THREAD_KEYS on Windows so it
188 is based on the version of the OS as defined by Microsoft in this web
189 page: http://tinyurl.com/2jqcmd
190 This fixes bugzilla #2753
192 USER VISIBLE CHANGES BETWEEN ACE-5.5.10 and ACE-5.6
193 ====================================================
195 . OpenVMS 8.3 on IA64 port
197 . Added autoconf support for Intel C++ 10.0
199 . Improved autoconf support on Linux, Solaris, NetBSD and HPUX
201 . CodeGear C++ Builder 2007 Update 2 support
203 . The netsvcs's client logging daemon has a new configuration option,
204 -llocal-ip[:local-port], which can be used to specify the local IP
205 address and port number for the client logging daemon's connection to
206 the server logging daemon. If the -l option is specified with an IP
207 address but not a port number, an unused port number is selected.
209 . A new ACE+TAO port to LabVIEW RT 8.2 with Pharlap ETS. The host build
210 environment is Windows with Microsoft Visual Studio .NET 2003 (VC7.1).
211 Please see the ACE-INSTALL.html file for build instructions.
213 USER VISIBLE CHANGES BETWEEN ACE-5.5.9 and ACE-5.5.10
214 ====================================================
216 . The ACE_utsname struct, used in the ACE_OS::uname() function when the
217 platform doesn't provide the standard utsname struct, was changed. It
218 defines a number of text fields and their types were changed from
219 ACE_TCHAR[] to char[] in order to be consistent with all other platforms.
220 This removes the need to write different code for platforms where
221 ACE_LACKS_UTSNAME_T is set and that have wide characters (most probably
222 Windows). Fixes Bugzilla #2665.
224 . The ACE::daemonize() "close_all_handles" parameter was changed from
225 an "int" to a "bool" to better reflect how it is used.
227 . VxWorks 6.5 support. Compilation of the core libraries has been validated
228 but no runtime testing has been performed.
230 . CodeGear C++ Builder 2007 support.
232 . The FaCE utility was moved from the ACE_wrappers/apps directory to
233 ACE_wrappers/contrib. It is used for testing ACE+TAO apps on WinCE.
234 See the ACE_wrappers/contrib/FaCE/README file for more information.
236 . ACE_INET_Addr::set (u_short port, char *host_name, ...) now favors IPv6
237 addresses when compiled with ACE_HAS_IPV6 defined and the supplied address
238 family is AF_UNSPEC. This means that if host_name has an IPv6 address in
239 DNS or /etc/hosts, that will be used over an IPv4 address. If no IPv6
240 address exists for host_name, then its IPv4 address will be used.
242 . Intel C++ 10.0 support
244 . Support for the version of vc8 for 64-bit (AMD64) shipped with the Microsoft
247 . Fixed ACE_Vector::swap() (bugzilla #2951).
249 . Make use of the Atomic_Op optimizations on Intel EM64T processors. The
250 Atomic_Op is now several times faster on EM64T then with previous versions
253 USER VISIBLE CHANGES BETWEEN ACE-5.5.8 and ACE-5.5.9
254 ====================================================
256 . Use Intel C++ specific optimizations for Linux on IA64
258 . Improved support for ACE_OS::fgetc. Added support for ACE_OS::fputc,
259 ACE_OS::getc, ACE_OS::putc and ACE_OS::ungetc.
261 . Added support for ACE_OS::log2(double) and improved support for
264 . Shared library builds on AIX now produce a libxxx.so file instead of the
265 previous practice of producing libxxx.a(shr.o).
267 . GCC 4.1.2 that comes with Fedora 7 seems to have a fix for the visibility
268 attribute we use for the singletons. F7 users will therefore need to
269 define the following in your config.h file.
270 ACE_GCC_HAS_TEMPLATE_INSTANTIATION_VISIBILITY_ATTRS 1
272 . Fixed (rare) problem in TP_Reactor where incorrect event handler was
275 . Reduced footprint on some platforms, particularly those that use
278 USER VISIBLE CHANGES BETWEEN ACE-5.5.7 and ACE-5.5.8
279 ====================================================
281 . Extended ACE_Event constructor with optional LPSECURITY_ATTRIBUTES
284 . Added support for QT4
286 . Added support to integrate with the FOX Toolkit (www.fox-toolkit.org)
288 . Added support for Microsoft Visual Studio Code Name "Orcas", which is
291 . Added ability to provide an optional priority when calling
292 ACE_Message_Queue_Ex::enqueue_prio(). There was previously no way
293 to specify a priority for queueing.
295 . Removed support for Visual Age on Windows.
297 . ACE will compile once again with ACE_LACKS_CDR_ALIGNMENT #defined.
299 . ACE_Process_Manager::terminate() no longer removes the process from the
300 process descriptor table; the pid remains available in order to call
301 ACE_Process_Manager::wait().
303 USER VISIBLE CHANGES BETWEEN ACE-5.5.6 and ACE-5.5.7
304 ====================================================
306 . ACE 5.5 contained a set of pragmas which prevented Visual Studio 2005 (VC8)
307 from issuing warnings where C run-time functions are used but a more
308 secure alternative is available. For more information on the C run-time
309 issues and Microsoft's response, please see the following MSDN page:
310 http://msdn2.microsoft.com/en-us/library/8ef0s5kh(VS.80).aspx.
311 In this beta, the pragmas which prevented the warnings have been removed.
312 The ACE library has been reviewed and most of the use of "unsafe" functions
313 has been fixed where possible. Since not all of the warnings emanating from
314 ACE are situations that can or should be fixed, the ACE VC8 projects will
315 prevent the warnings while building the ACE kit and its contained examples,
316 tests, etc. The warnings are disabled by adding Microsoft-specified macros
317 to the compile line via MPC. If desired, the warnings can be re-enabled by
318 regenerating the project files with different MPC features. Note, however,
319 that while ACE without warnings caused by the new C run-time functions, your
320 application builds may trigger these warnings either by use of the "unsafe"
321 C run-time functions or via use of an inlined ACE_OS method which uses it.
322 If the warning is caused by an ACE_OS method, there is a more safe alternate
323 available, probably located by appending _r to the method name (e.g.,
324 instead of using ACE_OS::ctime(), use ACE_OS::ctime_r()).
325 There are other cases where the compiler may have issued warnings and ACE
326 prevented this via a #pragma. These #pragmas have been removed as well.
327 This may cause your application builds to trigger more warnings from VC8
328 than past ACE versions. You should review your code and either correct
329 the code or disable the warnings locally, as appropriate.
331 . The "release" argument to a number of ACE_String_Base<> methods was changed
332 from int to bool to more accurately reflect its purpose. The following
333 methods were changed:
335 ACE_String_Base (const CHAR *s,
336 ACE_Allocator *the_allocator = 0,
339 ACE_String_Base (const CHAR *s,
340 ACE_Allocator *the_allocator = 0,
341 bool release = true);
343 ACE_String_Base (const CHAR *s,
345 ACE_Allocator *the_allocator = 0,
348 ACE_String_Base (const CHAR *s,
350 ACE_Allocator *the_allocator = 0,
351 bool release = true);
353 void set (const CHAR * s, int release = 1);
355 void set (const CHAR * s, bool release = true);
357 void set (const CHAR * s, size_type len, int release);
359 void set (const CHAR * s, size_type len, bool release);
361 void clear (int release = 0);
363 void clear (bool release = false);
365 Since ACE_String_Base forms the basis of the ACE_CString and ACE_TString
366 classes, this may ripple out to user application code. If you encounter
367 errors in this area while building your applications, replace the
368 int argument you are passing to the method now with either true or false.
370 . Solutions for the eVC3/4 platform have been removed from this
371 release. Note that we package WinCE projects/workspaces for use
374 . There were 3 new ACE_Log_Msg logging format specifiers added to make logging
375 easier for types that may change sizes across platforms. These all take one
376 argument, and the new formats are:
377 %b - format a ssize_t value
378 %B - format a size_t value
379 %: - format a time_t value
381 . The ace/Time_Request_Reply.h and ace/Time_Request_Reply.cpp files were
382 moved from $ACE_ROOT/ace to $ACE_ROOT/netsvcs/lib. The time arguments in
383 the public API to ACE_Time_Request were changed from ACE_UINT32 to time_t
384 and the portions of the on-wire protocol that contains time was changed from
385 ACE_UINT32 to ACE_UINT64. Thus, code that uses the ACE_Time_Request class
386 to transfer time information will not interoperate properly with prior
387 ACE versions. This will affect uses of the netsvcs time clerk/server.
389 . The portion of the ACE_Name_Request class that carries the on-wire seconds
390 portion of a timeout value was changed from ACE_UINT32 to ACE_UINT64. This
391 means that Name server/clients at ACE 5.5.7 and higher will not interoperate
392 properly with previous ACE versions' name servers/clients.
394 . In the ACE_Log_Record (ACE_Log_Priority, long, long) constructor, the
395 second argument, long time_stamp, was changed to be of type time_t. This
396 aligns the type with the expected value, a time stamp such as that returned
399 . Added support for VxWorks 6.x cross compilation using a Windows host
402 . Added support for VxWorks 6.x using the diab compiler
404 . The destructor of ACE_Event_Handler no longer calls
405 purge_pending_notifications(). Please see bugzilla #2845 for the full
407 (http://deuce.doc.wustl.edu/bugzilla/show_bug.cgi?id=2845)
409 USER VISIBLE CHANGES BETWEEN ACE-5.5.5 and ACE-5.5.6
410 ====================================================
412 . The ACE_TYPENAME macro has been added to those that are not
413 available when the ACE_LACKS_DEPRECATED_MACROS config option is set
414 (it is not set by default). You are encouraged to replace the use of
415 ACE_TYPENAME with the C++ typename keyword before the ACE_TYPENAME
416 macros is removed from ACE in the future.
418 . A new script, rm_exception_macros.pl, has been added to help users
419 remove the use of the ACE exception macros from their own code.
421 USER VISIBLE CHANGES BETWEEN ACE-5.5.4 and ACE-5.5.5
422 ====================================================
424 . The prebuild MPC keyword is now supported by the gnuace project type.
425 This fixes Bugzilla #2713.
427 . Support for Windows earlier than NT 4 SP2 was removed. ACE will not build
428 for Windows 95, 98, Me, etc. out of the box any longer.
430 . Reformat stringified IPv6 addresses to use [addr]:port when printing
431 addresses that contain ':' such as "::1".
433 . Added method to ACE_INET_Addr to determine if address is IPv6 or
436 . Fixed a bug in ACE_Async_Timer_Adapter_Timer_Queue_Adapter<TQ> where the
437 gettimeofday function of the timer queue was ignored when setting the alarm.
439 . Fixed a problem where, on Solaris 9 onwards, calling
440 ACE_OS::thr_create(THR_NEW_LWP) more than 2^15 (65535) times in a
441 process will fail. See changelog entry from "Wed Jan 3 22:31:05 UTC
442 2007 Chris Cleeland <cleeland_c@ociweb.com>" for more information.
444 . Fixed a bug in ACE_QtReactor where the two select() calls in that function
445 might select on different handler sets.
447 . ACE_SOCK_IO::recvv(iovec[], size_t, const ACE_Time_Value* = 0) and
448 ACE_SOCK_IO::sendv (const iovec[], size_t, const ACE_Time_Value* = 0) methods
449 were changed to specify the iovec count argument as int instead of size_t
450 since it gets reduced to int in the underlying OS calls (usually).
452 . The following deprecated methods were removed:
454 ssize_t ACE_SOCK_IO::recv (iovec iov[],
456 const ACE_Time_Value *timeout = 0) const;
458 ssize_t ACE_SOCK_IO::recv (iovec *io_vec,
459 const ACE_Time_Value *timeout = 0) const;
461 ssize_t ACE_SOCK_IO::send (const iovec iov[],
463 const ACE_Time_Value *timeout = 0) const;
465 These were previously replaced with more specific recvv() and sendv()
468 . The ACE_Service_Repository::find(const ACE_TCHAR name[],
469 const ACE_Service_Type **srp = 0,
470 int ignore_suspended = true) const
471 method's 'ignore_suspended' parameter was changed from int to bool to
472 reflect it's purpose as a yes/no indicator.
474 . Added --enable-ace-reactor-notification-queue configure script
475 option to the autoconf build for enabling the Reactor's userspace
476 notification queue (defines ACE_HAS_REACTOR_NOTIFICATION_QUEUE in
479 . The int ACE_OutputCDR::consolidate(void) method was contributed by
480 Howard Finer at Sonus Networks. This method consolidates any continuation
481 blocks used by an ACE_OutputCDR object into a single block. It's useful for
482 situations which require access to a single memory area containing the
483 encoded stream, regardless of its length, when the length cannot be known
486 . There are a number of new methods defined on ACE_String_Base<CHAR>:
488 size_t capacity (void) const: This method returns the number
489 of allocated CHAR units in the string object.
491 void fast_resize (size_t): This method manage the sizing/reallocating
492 of the string, but doesn't do the memory setting of resize().
494 bool operator!= (const CHAR *) const
495 bool operator== (const CHAR *) const: These methods compare the
496 string with a nul-terminated CHAR* string.
498 nonmember functions operator== and operator!= where also added
499 that compare const ACE_String_Base and const CHAR*; these make
500 it possible to switch ACE_String and CHAR* on either side of
503 Thank you to Kelly Hickel <kfh at mqsoftware dot com> for these additions.
505 . There are 2 new build options on the traditional make command:
506 dmalloc and mtrace. When specified at build time (e.g. make mtrace=1)
507 the PLATFORM_DMALLOC_CPPFLAGS and/or PLATFORM_MTRACE_CPPFLAGS values
508 are added to CPPFLAGS. For dmalloc, the PLATFORM_DMALLOC_LDFLAGS and
509 PLATFORM_DMALLOC_LIBS are added to LDFLAGS and LIBS, respectively.
510 Thank you to Howard Finer for supplying these additions.
512 . Added the ability to specify additional purify and quantify command-line
513 options by setting PLATFORM_PURIFY_OPTIONS and PLATFORM_QUANTIFY_OPTIONS,
514 respectively. Thank you to Howard Finer for supplying these additions.
516 . Added the ability to use trio (http://sourceforge.net/projects/ctrio/)
517 if platform lacks decent support for vsnprintf. trio support is
518 enabled by defining trio=1 in plaform_macros.GNU
520 . Removed Irix 5, DGUX, and m88k support
522 . Improved LynxOS 4.2 support
524 . VxWorks 6.4 support
526 . Added support for FC6. Because the GCC 4.1.1 version that gets shipped
527 has a fix for the visibility attribute we use for the singletons
528 you will need to define the following in your config.h file. This can't be
529 done automatically because SuSE 10.2 gets shipped with GCC 4.1.2 but
530 doesn't have the same fix
531 ACE_GCC_HAS_TEMPLATE_INSTANTIATION_VISIBILITY_ATTRS 1
535 USER VISIBLE CHANGES BETWEEN ACE-5.5.3 and ACE-5.5.4
536 ====================================================
538 . Added appropriate intptr_t and uintptr_t typedefs on platforms that
539 don't provide them (i.e. when ACE_LACKS_INTPTR_T is defined).
541 . Added ability to explicitly choose support for 32 bit or 64 bit file
542 offsets on all platforms. Define the _FILE_OFFSET_BITS preprocessor
543 symbol to either 32 or 64 to choose the desired number of file
544 offset bits. This preprocessor symbol is supported natively by most
545 UNIX and UNIX-like operating systems, and supported by ACE on
546 Windows. Use the new ACE_OFF_T typedef to refer to file offsets
547 across UNIX and Windows portably.
549 . 64-bit file offsets are now enabled by default in Win64
552 . Improved support for 64 bit platforms (64 bit addresses, etc).
554 . Added STL-style traits, iterators and a swap() method to the
555 ACE_Array_Base<> class template.
557 . Added STL-style traits and iterator accessors to the
558 ACE_Hash_Map_Manager_Ex<> class template, as well as new find() and
559 unbind() methods that return (as an "out" parameter) and accept
560 iterators, respectively.
562 . Greatly improved event handler dispatch performance in
563 select()-based reactors (e.g. ACE_Select_Reactor and ACE_TP_Reactor)
564 for large handle sets on Windows. Previous event handler search
565 were linear, and are now constant on average.
567 . Addressed a number of Coverity errors (CHECKED_RETURN, DEADCODE,
568 LOCK, USE_AFTER_FREE, RESOURCE_LEAK, FORWARD_NULL).
570 . Added STL-style "element_type" trait to all ACE auto_ptr class
573 . Removed support for LynxOS 3.x.
575 . Resolved Bugzilla #2701 to ensure fini() is called for all
576 Service Objects upon calling ACE_Service_Config::close()
578 . VxWorks 5.5.2 has been tested, for ACE the support is exactly
579 the same as for VxWorks 5.5.1. No specific defines or flags have
582 USER VISIBLE CHANGES BETWEEN ACE-5.5.2 and ACE-5.5.3
583 ====================================================
585 . Added the base projects for executionmanager_stub and plan_generator.
587 . Added the ACE_Hash_MultiMap_Manager class and its test file.
589 . Changed the ACE_Synch_Options::operator[] method to return bool rather than
590 int. The value returned is a yes/no indication of whether or not the
591 specified option(s) are set in the object.
593 . Changed the prototype(s) for ACE::debug () to return (and take) a
594 bool. This is consistent with the original intent for this
595 feature. If you have been using it like 'ACE::debug () > 0' or
596 'ACE::debug (1)', you may have to rebuild ACE. The value of the
597 ACE_DEBUG environment variable can be used to specify the initial
598 value for ACE::debug(), at the process start up.
600 . An assembler (within a C source file) based implementation for SPARC
601 of atomic operations suitable for use with the
602 ACE_Atomic_Op<ACE_Thread_Mutex, long> and
603 ACE_Atomic_Op<ACE_Thread_Mutex, unsigned long> specializations has
604 been added. Currently, it can only be enabled by setting the
605 atomic_ops_sparc make macro to 1 when using the GNUACE build system with
606 the Solaris SunCC compiler. It should be noted that this requires the
607 -xarch=v8plus (or higher) be added to the CFLAGS make macro or the
608 assembler code will not compile.
610 . The ACE_Message_Queue_Ex_N<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL> class
611 is new, contributed by Guy Peleg <guy dot peleg at amdocs dot com>.
612 ACE_Message_Queue_Ex_N<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL> is
613 similar to ACE_Message_Queue_Ex in that the object queued is a
614 template parameter. However, ACE_Message_Queue_Ex_N allows the
615 enqueueing and dequeueing of multiple chained objects at once. This
616 wasn't added to ACE_Message_Queue_Ex because the chained object
617 functionality requires the ACE_MESSAGE_TYPE class to have a
618 ACE_MESSAGE_TYPE *next (void) const method, analogous to
619 ACE_Message_Block::next(), to follow the chain and this would
620 probably break existing applications using ACE_Message_Queue_Ex.
621 The ACE_wrappers/tests/Message_Queue_Test_Ex.cpp test has an example of
622 how to use the new class.
624 . The selector and comparator function pointer arguments to ACE_OS::scandir()
625 and ACE_Dirent_Selector are now marked as extern "C" to enforce their
626 use with a C RTL function. User code that defines functions which are
627 passed as the selector or comparator arguments which are not declared
628 extern "C" may generate compile warnings. To resolve this, add extern "C"
629 to the function's signature. See ACE_wrappers/tests/Dirent_Test.cpp for
632 . To address a problem in the ACE string interface that prevented
633 substring or character searches in very large strings (e.g. greater
634 than the maximum value of an ssize_t type) from being correctly
635 reported to the caller, the find(), rfind() and strstr() methods now
636 return an unsigned integer (size_t) instead of a signed one
637 (ssize_t). Affected classes include:
644 Unless you have been explicitly using -1 instead of npos when
645 comparing the return value of find(), rfind() and strstr(), and/or
646 assigning the return value to ssize_t you should not see any
647 difference. A new size_type typedef has been added to the ACE string
648 class to aid developers. This typedef is analogous to the standard
649 C++ string::size_type typedef.
651 The ACE_String_Base<>::strstr() documentation and the default
652 rfind() argument erroneously referred to -1 instead of npos. Those
653 instances have been corrected.
655 To summarize, a "no position" condition is denoted using the npos
656 constant, not -1. It can be referred directly by scoping it with the
657 appropriate string class (e.g. ACE_CString::npos, ACE_WString::npos,
660 . Changing the shared library extension for hpux ia64 to ".so". On
661 HP-UX 11i Version 1.5 the naming scheme is lib*.sl for PA and
664 . The ACE_Refcounted_Auto_Ptr reset() and release() methods were changed
665 per Bugzilla #1925. They will both now detach from the underlying
666 ACE_Refcounted_Auto_Ptr_Rep object; reset() will create a new one for
667 the new pointer specified as its argument. This change may cause referenced
668 objects to be deleted in cases where previous ACE versions would not have.
670 . The return type of "ACE_Refcounted_Auto_Ptr::null (void) const" changed
671 from int to bool. It's possible values, true and false, have not changed.
673 . TTY_IO now accepts "none" as a valid parity value. Due to this change
674 'parityenb' member is now deprecated and will be removed in the future.
675 The users of TTY_IO class should change their code to use only 'paritymode'
676 member for parity control and leave 'parityenb' unchanged (it is
677 enabled by default in class constructor).
679 . Support for Intel C++ 9.1 on Windows and Linux
681 . VxWorks 6.3 support
683 . Fixed Bugzilla #2648 to make sure ACE_Service_Object::fini()
684 is called iff ACE_Service_Object::init() succeeded, as per
687 . Added preliminary support for Mac OS X 10.4 on Intel CPU's.
689 . Fixed Bugzilla #2602 to re-enable XML Service Configurator
692 USER VISIBLE CHANGES BETWEEN ACE-5.5.1 and ACE-5.5.2
693 ====================================================
696 - VxWorks 6.2 for the rtp model using pthread support
697 - OpenVMS 8.2 for Alpha
699 . Removed code and configurations that provided support for:
700 - Visual C++ 6.0 and 7.0
703 - KAI C++ on all platforms
705 . Explicit template instantiation support has been removed. This effectively
706 removes support for Sun Forte 6 and 7 which required explicit template
707 instantiation to build ACE reliably.
709 . Added support for multiple independent Service Repositories through
710 configuration contexts called "Gestalt". Full backwards compatibility
711 is maintained through the existing ACE_Service_Config static methods,
712 while direct individual repository access is enabled through instances
713 of the new ACE_Service_Gestalt class. ACE_Service_Config has changed to
714 a specialization of ACE_Service_Gestalt and is only responsible for the
715 process-wide configuration.
717 . To support dynamically-sized ACE_Log_Record messages, the netsvcs
718 logging components now use ACE CDR encoding and transfer mechanisms
719 inspired by the examples in Chapter 4 of the C++NPv1 book.
720 The client and server logging daemons in ACE 5.5.2 and forward will
721 not interoperate with those in previous ACE versions.
723 . Added a wrapper for the sendfile API (ACE_OS::sendfile()).
725 . Added support for netlink sockets on Linux.
727 . Added a new method, ACE_Task::last_thread(). This method returns the thread
728 ID (ACE_thread_t) of the last thread to exit from the ACE_Task object.
729 Users checking to see if a thread is the last one out (for example, to know
730 when to perform cleanup operations) should compare the current thread ID to
731 the return value from last_thread(). This is a change from the previously
732 recommended practice (C++NPv2, page 189) of comparing the return value of
735 . Changed the first argument to ACE_OS::strptime() to be 'const' which
736 matches its usual usage in POSIX strptime(). This change allows users to
737 pass const strings in - a common use case.
739 . Made part of the file support in ACE 64bit but we have some places where
740 32bit types are used, this could lead to some conversion warnings which
741 will be addressed in the near future, but getting everything 64bit
742 compliant is a lot of work.
744 USER VISIBLE CHANGES BETWEEN ACE-5.5 and ACE-5.5.1
745 ====================================================
747 . Added support for the --enable-symbol-visibility configure option
748 to the autoconf build infrastructure instead of solely relying on
749 feature tests to enable/disable symbol visibility support. This
750 avoids build problems with icc, etc.
752 . Added support for the --enable-fl-reactor configure option to the
753 autoconf build infrastructure to build the ACE_FlReactor library.
755 . Added support for the --enable-qt-reactor configure option to the
756 autoconf build infrastructure to build the ACE_QtReactor library.
758 . Added support for the --enable-xt-reactor configure option to the
759 autoconf build infrastructure to build the ACE_XtReactor library.
761 . Fixed a bug that would cause timer IDs from ACE_Timer_Heap to be
762 improperly duplicated under certain conditions (Bugzilla #2447).
764 . Fixed ACE_SSL_Context::private_key(), context(), and dh_params() methods
765 to allow retrying a file load after a failed call.
767 . Fixed ACE_SSL_Asynch_Stream so it can be instantiated; also moved the
768 declarations for ACE_SSL_Asynch_Read_Stream_Result,
769 ACE_SSL_Asynch_Write_Stream_Result, and ACE_SSL_Asynch_Result classes
770 to the ace/SSL/SSL_Asynch_Stream.h file so applications can see them.
772 USER VISIBLE CHANGES BETWEEN ACE-5.4.10 and ACE-5.5
773 ====================================================
775 . Added a platform macros option "templates=manual", currently only
776 applies to AIX 5.3 with XL 7 compiler. It allows the user to tell the
777 compiler to set -qnotempinc and -qnotemplateregistry and works well
780 . ACE and its tests compile error free with GCC 4.1 pre release.
782 . ACE_Recursive_Thread_Mutex::get_nesting_level() fixed for 64-bit Windows
783 XP on amd64/EM64T hardware.
785 . Many build-time fixes for Windows Mobile 5 and Windows PocketPC 2003 using
786 Visual Studio .NET 2005 (VC8).
788 . Added support for the --enable-tk-reactor configure option to the
789 autoconf build infrastructure to build the ACE_TkReactor library.
791 USER VISIBLE CHANGES BETWEEN ACE-5.4.9 and ACE-5.4.10
792 ====================================================
794 . Fixed a bug in ACE_Timer_Heap_T::cancel().
796 . Improved ACE_Time_Value support for boundary conditions.
798 . Fixed problems with operator placement delete on certain C++ compilers.
800 . Fixed a bug with the ACE_SPIPE_Acceptor on Windows.
802 . Correctly set sockaddr_in.sin_len and sockaddr_in6.sin6_len on
803 platforms that have these fields.
805 . Avoided problems with namespace pollution for max() macros.
807 . Many fixes for ACE_LACKS* and ACE_HAS* macros for autoconfig.
809 USER VISIBLE CHANGES BETWEEN ACE-5.4.8 and ACE-5.4.9
810 ====================================================
812 . Added dozens of new ACE_LACKS and ACE_HAS defines which are used to
813 simplify the ACE_OS layer
815 . Constructors of ACE_Time_Value have been made explicit to prevent
816 implicit conversions.
818 . Added a shutdown() method to ACE_Barrier. The new method aborts the
821 . Changed the behavior of ACE_Message_Queue::enqueue_head() and
822 enqueue_tail(). If the enqueued message block has other blocks
823 chained to it via its next() pointer, the entire chain of blocks
824 will be enqueued at once.
826 . Improved the support for high-resolution timers with
827 ACE_Timer_Queue_Adapter.
829 . Make it possible to disable file caching in JAWS.
831 . Improved ACE_Pipe implementation so that it uses localhost to avoid
834 . Added Unicode support to the Service Configurator.
836 USER VISIBLE CHANGES BETWEEN ACE-5.4.7 and ACE-5.4.8
837 ====================================================
839 . Improved IPv6 support
841 . Improved 64bit portability
844 - Improved documentation.
845 - It is now possible to request infinite timeout in portable manner.
846 This can be achieved by setting negative value to readtimeoutmsec.
847 - Various bugs fixed and portability issues resolved.
849 . Subset ACE for TAO and TAO Services
851 . Support for Intel C++ 9.0 on Windows and Linux
853 . Support for Microsoft Visual Studio 2005 (aka VC8) for Win32 as well
854 as the Windows CE platforms Pocket PC 2003 and Windows Mobile 5.
855 Solution/project files are generated with an appended "_vc8" for
856 Win32 and "_WinCE" for the CE platforms. See
857 ACE_wrappers/docs/CE-status.txt for more information.
859 . Completed implementation of ACE_Dev_Poll_Reactor using the Linux epoll
860 facility; tested on Red Hat Enterprise Linux 4.
862 . The in-memory size of an ACE_RB_Tree will be smaller due to rearranged
863 placement of pointers.
865 . Added an optimization to CDR stream to ignores alignment when marshaling
866 data. Use this new ACE_LACKS_CDR_ALIGNMENT compile-time option only
867 when the ACE_DISABLE_SWAP_ON_READ macro is enabled. This new option
868 requires ACE CDR engine to do both marshaling and demarshaling, and
869 when this option is enabled the encoded streams are no longer
870 compliant with the CORBA CDR specification.
872 . Developed Feature Oriented Customizer (FOCUS) tool to enable
873 specialization of middleware frameworks such as Reactor and Protocol
874 framework. FOCUS provides an XML based transformation engine, where
875 the transformations to specialize the components are captured in XML
876 file and a weaver specializes the code.
878 . Added support for unrolling ACE_OS::memcpy copy loop where
879 applicable to improve performance. Autoconf tests empirically
880 determine whether loop unrolling is at least 10% better than default
883 . Added support for an ACE "versioned" namespace. When enabled, ACE
884 library sources will be placed within a namespace of the user's
885 choice or a namespace of the form ACE_5_4_7 by default, where
886 "5_4_7" is the ACE major, minor and beta versions. The default may
887 be overridden by defining the ACE_VERSIONED_NAMESPACE_NAME
888 preprocessor symbol. Enable overall versioned namespace support by
889 adding "versioned_namespace=1" to your MPC default.features file.
891 USER VISIBLE CHANGES BETWEEN ACE-5.4.6 and ACE-5.4.7
892 ====================================================
894 . Support for shared libraries with VxWorks
896 . Support for Solaris 10 on x86 with Sun Studio 10 (C++ 5.7).
898 . Extended ACE_OS::event_xxx implementation to support platforms
899 having either PThread support with Process Shared condition
900 variables or POSIX semaphores with named (process shared)
901 semaphore support or using the new FIFO based semaphores.
903 . ACE_OS::closesocket() no longer calls ACE_OS::shutdown() on any platform
904 while closing the socket. It previously called ACE_OS::shutdown() on
905 HP-UX. Removing this call fixes the fork-and-close programming paradigm
906 that's common to many networked applications.
909 - Support for message fragmentation. This will allow
910 for messages larger than 64K.
911 - Support for flow control.
912 - Timed recv() in RMCast::Socket.
913 - Per-instance configurable protocol parameters (e.g., message
914 retention time, NAK timeout, etc).
916 USER VISIBLE CHANGES BETWEEN ACE-5.4.5 and ACE-5.4.6
917 ====================================================
919 . Updated RMCast to include
920 - Reactor-compatible interface.
921 - Message unavailability reporting.
922 - Protocol documentation.
924 . Added support for 64bit Visual Age on AIX
926 . Improved g++ 4.0 support. A number of RTTI related problems have been
931 . Fixed memory leaks ACE_DLL and ACE_Log_Msg classes.
933 . The ACE::ICMP_Socket and ACE::Ping_Socket classes were moved out of
934 the ACE namespace and "flattened" to ACE_ICMP_Socket and
935 ACE_Ping_Socket to be consistent with the rest of ACE.
937 . ACE_INET_Addr::set_address() - fixed a possible struct member
938 alignment issue when building an IPv4-mapped IPv6 address.
940 . Added a new ACE::wild_match() function to match a string based on
943 . Added efficient overloads for string concatenation to the
944 ACE_String_Base class.
946 . Added support for the use of pthread_getschedparam on MacOS X.
948 . Fixed an issue with static initialization of TSS related classes on
949 static builds for Windows.
951 USER VISIBLE CHANGES BETWEEN ACE-5.4.4 and ACE-5.4.5
952 ====================================================
954 . Remove special handling in the Thread Specific Storage(TSS) code
955 that released the TSS key for ACE_TSS<TYPE>. ACE_TSS<TYPE> has
956 been changed to explicitly free the TSS key when necessary.
958 . On Win32 systems: detect thread termination via a hook in DLLMain
959 for ACE.dll. This allows cleanup of TSS objects for non-ACE threads
960 that use ACE functions. The most common case was threads that used
961 ACE logging. Formerly any TSS objects created by these threads would
964 . Added support for GNU G++ 4.0. The x.4.5 beta takes advantage of
965 g++ 4.0's symbol visibility. This feature is conceptually similar
966 to MS Windows "__declspec(dllexport)" DLL functionality. Using this
967 new g++ feature results in substantially improved ACE/TAO/CIAO
968 shared library binaries. A subset of the improvements include the
971 * The number of unnecessarily exported DSO/DLL symbols is
972 greatly reduced, resulting in faster program start times.
974 * Improved performance since run-time indirection of internal
975 symbols is no longer needed.
977 No changes to the ACE/TAO sources were necessary to support this
978 feature since the required visibility attributes were hidden behind
979 the various "*_Export" macros (formerly only useful for MS Windows
980 DLLs) used throughout ACE/TAO.
982 . The ACE_Reactor destructor will now call close() on the referenced reactor
983 implementation. This assures that all handlers are notified before the
984 ACE_Reactor object that's most likely referenced in these handlers is
985 invalid. Although this should not be a user-visible change, it did catch
986 some ACE tests off guard destroying reactor implementations and ACE_Reactor
987 interfaces in the wrong order, so it may come up in the field as well.
988 When using dynamically allocated reactor implementations, do not destroy
989 the implementation object before the ACE_Reactor interface object. Use of
990 the ACE_Reactor constructor's delete_implementation argument (with a value
991 of 1) is recommended when dynamically allocating reactor implementations.
993 . Improved performance of HTBP by not requiring a lookup of peer hostname.
995 . Added new ACE_SizeCDR stream which allows one to calculate size of the
996 representation without writing anything.
998 . Number of improvements in RMCast, reliable multicast implementation.
1000 USER VISIBLE CHANGES BETWEEN ACE-5.4.3 and ACE-5.4.4
1001 ====================================================
1003 . The ace-config script has been replaced by pkg-config metadata files
1004 which are installed in ${prefix}/lib/pkgconfig by the automake build.
1006 . Remove ACE_OS::gets() implementation. While this ACE implementation
1007 of gets() did not contain the security holes that all standard
1008 gets() implementations have, keeping it around only serves to foster
1009 confusion since (1) some may incorrectly assume that this
1010 ACE-specific gets() implementation has the same holes as standard
1011 ones, and (2) invoking it with a default size argument so that it
1012 looks like a standard gets() call results in behavior that is
1013 different from the standard. Use ACE_OS::fgets() instead.
1015 . Removed ACE_Unbounded_Set_Ex, this gave the false idea that it had
1016 thread safe iterators. Use ACE_Unbounded_Set instead
1018 . Improved VxWorks support for static libraries. Shared libraries do cause
1019 several known problems which will be fixed in the x.4.5 release.
1021 . Removed the usage of the ACE_x_cast macros, we are using the C++ casts
1022 from now on. The ACE_x_cast macros are deprecated and will be removed
1023 after the x.5.1 release
1025 . Some improvements in autoconf support; better detection of available
1026 OS and compiler features.
1028 . Fixed bugs in ACE TSS emulation
1030 USER VISIBLE CHANGES BETWEEN ACE-5.4.2 and ACE-5.4.3
1031 ====================================================
1033 . Improved Cygwin 1.5.12 support, 90% of the tests now succeed
1035 . Improved OpenVMS support.
1037 . Added ability to use fltk with Cygwin/MinGW
1039 . Added ACE_INT64 that defines a native 64 bit type.
1041 . Added 'q' as usable specifier for ACE_Log_Msg to print out int64 bit number.
1043 . Added better support for Intel C++ compilers.
1045 . Improved HPUX support.
1047 . Added a new directory ("ACE_wrappers/protocols/ace") for new protocols
1048 that are not directly components of ACE, but are relate to ACE and
1049 defined a new protocol, HTBP (Hypertext Tunneling, Bidirectional
1050 Protocol) providing ACE_Acceptor/Connector/Stream semantics over a
1051 connection owned by an HTTP proxy. Test cases in
1052 ACE_wrappers/tests/HTBP provide examples of use.
1054 . Performace enhancement in TP_Reactor's handle_timer_events method [Bug
1057 . Various changes to permit ACE to execute on HP NonStop platform (e.g
1058 support for its pthreads version).
1060 . Updated HP NonStop configuration files (config-tandem-nsk).
1062 . The "ACE" pseudo-namespace is now a true C++ namespace. Transitional
1063 pseudo-namespaces that were only meant to be used internally by ACE,
1064 such as "ACE_Sock_Connect", no longer exist.
1066 . ACE_CDR::Boolean type is now a true C++ "bool" on all platforms except
1067 MSVC++ 6. We plan to deprecate MSVC++ 6 support sometime after the
1068 x.5 release of ACE+TAO+CIAO, so we recommend you start migrating to a
1069 later version of MSVC++.
1071 . More GNU g++ 3.4.x fixes.
1073 . Added ICMP and "ping" socket support.
1075 . Added mkstemp() emulation.
1077 . Fixed problem on Linux < 2.5.47 platforms where equality comparison of
1078 two logically equal sockaddr_in structure instances would incorrectly
1081 . Support for wide characters has been improved on non-Windows
1084 . A number of Windows CE problems have been fixed.
1086 . ACE's loading of DLLs (for example, as a result of loading synamic
1087 services) has been changed to use the native OS's facilities for
1088 locating the DLL instead of searching LD_LIBRARY_PATH (or its
1089 equivalent) then loading the DLL using a full pathname. This restores
1090 enforcement of a platform's loading and security policy. To use the
1091 old DLL locating method, add ACE_MUST_HELP_DLOPEN_SEARCH_PATH to your
1092 config.h file before building ACE.
1094 . A number of errors in the APG example programs have been corrected.
1096 . Select_Reactor and Priority_Reactor performance improved. [Bug 1890]
1098 . Wide-char functionality on POSIX (Linux, etc.)
1100 . TSS memory leak fixes [Bug 1542]
1102 . Ported to HPUX 11i v2 on Itanium
1104 . Added code to ACE for platform RedHat AS 3.0 on Opteron.
1106 . Changed ACE::crc32() family of functions to NOT fold in the length of
1107 the string/buffer/iovec into the CRC.
1110 USER VISIBLE CHANGES BETWEEN ACE-5.4.1 and ACE-5.4.2
1111 ====================================================
1113 . Support for g++ 3.4.1.
1115 . All ACE Makefiles, project files, etc, are now generated by OCI's
1116 "MakeProjectCreator" (MPC) tool. Makefiles and project files for
1117 commonly used configurations have been pre-generated and distributed
1118 with the beta(s). Please see:
1120 $ACE_ROOT/ACE-INSTALL.html
1122 for information on how to use MPC with ACE.
1124 . Improved Doxygen documentation.
1126 . Reduced header file dependencies, which should speedup compilation
1127 and help minimize static footprint.
1129 . ACE now requires support for the following standard C++ features:
1135 - "explicit" keyword
1137 - C++ casts (e.g. static_cast<>, reinterpret_cast<>, dynamic_cast<>
1140 If you're using a compiler that does NOT support these features
1141 please contact Steve Huston <shuston@riverace.com> for support.
1143 . Changed the select()-based reactor implementations to scan for
1144 broken handles to remove based on the registered handles, not on
1145 event handlers. This allows for bad handles to be removed from the
1146 reactor even if the event handler doesn't implement get_handle() the
1149 . Support for Pthreads native recursive mutexes was added. This
1150 capability is specified to ACE_OS::mutex_init() as an optional
1151 argument, lock_type. To fix confusion from an earlier attempt to add
1152 this functionality, the meaning of the old 'type' argument to
1153 ACE_OS::thread_mutex_init() is changed. It previously combined the
1154 scope and type. Now it is just the type (e.g. recursive), as the
1155 scope is inherent in the method used. For clarification on
1156 ACE_HAS_RECURSIVE_MUTEXES, it means that the platform is capable of
1157 them, not that they always are, as one would expect. However, before
1158 Pthreads had recursion added, it was never optional. Now it is.
1160 . Initial support for new Linux sys_epoll() interface in
1161 Dev_Poll_Reactor. The obsolete Linux /dev/epoll interface is no
1164 . Improved Cygwin support.
1165 - Threading works without problems.
1166 - Problems with shared memory, process shared mutexes, multicast and
1167 some other small things still exist.
1170 - This is for the latest version of OpenVMS with all available ECOs
1171 applied. Basic stuff works without problems. Advanced features
1172 still need some work.
1174 . Usage of ASYS_INLINE is deprecated in ACE. Use ACE_INLINE instead.
1176 . All inline source files now end in ".inl". The previous ".i"
1177 extension is generally used for preprocessed C sources.
1179 . Autoconf support has been improved and fixed on a number of
1180 platforms, including the BSD variants (e.g. FreeBSD). It is still
1181 not the preferred way to configure most platforms, but it is ready
1182 for wider testing. Please report any problems found to
1183 ace-bugs@cs.wustl.edu.
1185 . A number of fixes were made to quiet compile errors and warnings on
1188 . For builds on AIX using Visual Age C++, the make rtti option default
1189 was changed to 1, enabling RTTI by default.
1191 . ACE_Service_Repository::remove() has a new, optional argument that
1192 can receive the service record pointer for the removed service. If
1193 the pointer is returned to the caller, it is not deleted. If the
1194 pointer is not returned to the caller (the default) it is deleted
1195 (this is the historic behavior).
1197 . The tutorials in ACE_wrappers/docs have been removed. They were not
1198 being maintained and caused confusion in a number of cases. Now that
1199 there are complete examples that match the printed books (C++NPv1,
1200 C++NPv2, APG), the older tutorials are no longer useful. Please see
1202 $ACE_ROOT/examples/C++NPv1/
1203 $ACE_ROOT/examples/C++NPv2/
1204 $ACE_ROOT/examples/APG/
1206 for the source code of the examples in those books.
1208 . ACE_String_Base::fast_clear() is a new method which sets the string
1209 length to 0. Doesn't release string-allocated memory, but if the
1210 memory was externally supplied, it is no longer referenced from the
1213 . A true C++ "bool" is now used as the CDR stream boolean type, if
1214 supported by the compiler.
1216 . Renamed AIX 5L configuration header from config-aix5.1.h to
1219 . All C++ equality, relational and logical operators now return bool
1220 instead of int, as is the norm for modern C++.
1222 . Added new ACE_OS::realpath() implementation. Contributed by Olli
1223 Savia <ops at iki dot fi>
1226 USER VISIBLE CHANGES BETWEEN ACE-5.4 and ACE-5.4.1
1227 ====================================================
1232 . Fixed "make install" support in ACE+autoconf configurations.
1234 . Fixed autoconf support on Solaris.
1236 . Corrected invalid `aux' directory (on MS Windows) found in ACE
1239 . ACE/TAO build now without problems with MinGW and all ACE tests run
1240 now without problems
1242 . Added some more support for the new CBuilderX Preview compiler, this
1243 is not 100% ready yet because the compiler is still a preview and
1244 has its own problems.
1246 . Added Visual SlickEdit 8.1 MPC template
1248 . Added workaround for compile problems in Borland Release builds
1250 . Cygwin 1.5.9 is now supported
1252 . Tests for IPV6 have been added
1254 . Implement lstat() so that it'll use stat() on platforms that don't
1257 . Problems related to ACE_Event_Handler usage in WFMO_Reactor was
1260 . A wrapper for rmdir () has been added.
1262 . Threads spawned in thread-per-connection mode never inherited the
1263 priority. This problem was fixed and this fix is consistent with the
1266 . Fixed memory leaks with ACE_String_Base::resize ()
1268 . Enable the usage of native recursive mutexes for the implementation
1269 of ACE recursive mutexes on Linux.
1271 . The ACE Proactor framework can now be enabled for AIX 5.2. Since AIO
1272 functionality is not run-time enabled by default on AIX 5.2, the ACE
1273 Proactor code is not built by default on AIX. To enable it, the
1274 config.h file must contain #define ACE_HAS_AIO_CALLS before
1275 including the config-aix-5.1.h file.
1277 . The ACE_POSIX_CB_Proactor implementation is now built on all
1278 platforms except LynxOS.
1281 USER VISIBLE CHANGES BETWEEN ACE-5.3.6 and ACE-5.4
1282 ==================================================
1286 . Added a new makefile commandline flag, static_link, that can be
1287 used to force static linking when static_libs_only is turned on. It
1288 uses the new STATIC_LINK_FLAG variable and is currently only
1289 implemented for for GNU ld, i.e., it adds the "-static" option to
1290 LDFLAGS. It's turned off by default since using it causes the
1291 footprint to go up by almost 1 MB on Linux, since it links all the
1292 system and compiler .a files, but can be turned on if users
1293 want/need to use it, by enabling both static_libs_only and static_link.
1296 . Added macros ACE_USES_GPROF which enables users to use gprof in a
1297 multithreaded environment with ACE libs.
1299 . Added a new functor template class, ACE_Malloc_Lock_Adapter_T,
1300 that's used by ACE_Malloc_T as a factory for the ACE_LOCK template
1301 parameter, and allows the use of locking strategy classes, like
1302 ACE_Process_Semaphore and ACE_Thread_Semaphore that don't have a
1303 satisfactory ctor taking a single required ACE_TCHAR* parameter, to
1304 be adapted to work with ACE_Malloc_T.
1306 . The source code examples from "The ACE Programmer's Guide" book by
1307 Huston, Syyid, and Johnston, are now located in
1308 $ACE_ROOT/examples/APG.
1310 . Support for GNU autoconf is now in ACE. Please see ACE-INSTALL.html
1313 . Fixed problems that prevented ACE from being compiled on LynxOS
1316 . Fixed compilation error which prevented ACE from being compiled when
1317 ACE_COMPILE_TIMEPROBES was set to 1.
1319 . Preliminary support for Tandem NSK has been added.
1321 . Lots of bug fixes with TLI and XPG5. Please see $ACE_ROOT/ChangeLog
1324 . Fixed ACE_OS::event_timedwait() and ACE_OS::event_wait() so that
1325 they use a while loop around the ACE_OS::cond_[timed]wait() calls to
1326 avoid problems with spurious wakeups, etc.
1328 . ACE's wrapper around getipnodebyname() and getipnodebyaddr () has
1329 been made go through the IPv4-only case on ACE_WIN32. Since Windows
1330 IPv6 implementation doesn't offer support (at thistime) for
1331 getipnodebyname() the code has been changed to use the IPV4 part of
1334 . Install with Borland C++ of ACE library fixed
1339 . Fixed memory leak in ACEXML parser.
1341 . Fixed implementations of rewind() in all the CharStreams. They were
1344 . Fixed bugs in the parser associated with incorrect handling of PE
1345 References for keywords.
