Added support for Sun Studio 12 Update Pack 1 . Fixed compile problems when using Windows CE x86 release mode . Fixed compile problems for FreeBSD USER VISIBLE CHANGES BETWEEN ACE-5.6.9 and ACE-5.7.0 ==================================================== . Added support for the VxWorks vxAtomicLib which is available with VxWorks 6.6 and newer. If you don't want to use this library undef ACE_HAS_VXATOMICLIB in your config.h file . Added support for C++ Builder 2009 Update 3 . Added support for ACE/TAO using the CEGCC project . Added support for upcoming Fedora 11 and OpenSuSE Factory USER VISIBLE CHANGES BETWEEN ACE-5.6.8 and ACE-5.6.9 ==================================================== . Removed Borland/CodeGear C++ Builder 2007 support. If you'd like to fund this support please let us know. . Removed VxWorks 5.5.x, 6.2, and 6.3 support. If you'd like to fund this support please let us know. . Improved Unicode support. . Added support for the native Windows Vista and Windows Server 2008 condition variables. These has to be enabled at compile time, and when enabled the application can only run on Vista or Server 2008. Add ACE_HAS_WTHREADS_CONDITION_VARIABLE to your config.h file to enable these . Fixed a bug when trying to read a file of 1 byte when unicode is enabled . Improved the Windows CE port . Fixed several Klocwork reported issues . Added support for MinGW 3.15 . Added support for Incredibuild, which is an MSVC++ feature that optimizes compiles via distributing builds. USER VISIBLE CHANGES BETWEEN ACE-5.6.7 and ACE-5.6.8 ==================================================== . Added a new function ACE::isdotdir() which determines if a specified pathname is "dot dir" (ie. "." or ".."). ACE::isdotdir() is significantly faster than pair of strcmp() calls. . Last micro release that is maintained for Borland/CodeGear C++ Builder 2007 and Intel C++ on Windows. . Fixed crash when ACE thread tries to inherit the logging attributes from non ACE threads. . Fixed many small compile and test errors that occur on some platforms. . Fixed log output formatting on some platforms. . Bugs fixed: 2748, 3164, 3480, 3494, 3502, 3541, 3542, 3544, 3557. USER VISIBLE CHANGES BETWEEN ACE-5.6.6 and ACE-5.6.7 ==================================================== . Changed the automake build's feature test for a "usable" config to warn on failure instead of exiting with an error. This should make it easier to diagnose configure failures, as the script will now generate a config.h file even when the test fails. . Removed borland MPC template, use the bmake template from now . Added Windows Mobile 6 support and improved the WinCE port . Removed BCB6 and BCB2006 support . Added BCB2009 MPC template . Updated stat struct on Windows CE to match the stat struct on other platforms so that application code can be written portable . Added new ACE_OS wrappers: raise, atof, atol, isblank, isascii, isctype, and iswctype . Added ACE_OS wrapper for narrow-char version of strtoll. . ACE_OS wrappers for wide-char versions of strtol, strtoul, strtoll, and strtoll. . Added Visual Studio 2010 (vc10) support . Added a new feature for the "Traditional Make" build facility to allow building for multiple architectures out of a single source directory. To use this facility, set the ARCH make variable. The ARCH value will be used to add a subdirectory layer below the source directory where the traditional .shobj, .obj, etc. directories will be placed. . Added support for HP-UX 11iv3 on Integrity using aC++ . ACE (and TAO) can now be built using GNU make and the Microsoft Visual C++ compiler and linker. See include/makeinclude/platform_win32_msvc.GNU for more details. . Added support for FC10 USER VISIBLE CHANGES BETWEEN ACE-5.6.5 and ACE-5.6.6 ==================================================== . Added an option to the ACE_Process_Options class to use a wchar_t environment buffer on Windows. . A new configure option, --enable-rcsid, was added to the autoconf build. This is used to embed RCS IDs in object files. . A new method was added: void ACE_Time_Value::msec (ACE_UINT64&) This method, like the existing msec(ACE_UINT64&)const method, obtains the time value in milliseconds and stores it in the passed ACE_UINT64 object. This method was added so that msec(ACE_UINT64&) can be called on both const and non-const ACE_Time_Value objects without triggering compile errors. Fixes Bugzilla #3336. . Added ACE_Stack_Trace class to allow users to obtain a stack trace within their application on supported platforms. A new conversion character, the question mark, was added to ACE_Log_Msg for stack trace logging. . Added iterator support to ACE_Message_Queue_Ex class. The resulted in the addition of ACE_Message_Queue_Ex_Iterator class and ACE_Message_Queue_Ex_Reverse_Iterator class. . Renamed gperf to ace_gperf to prevent clashes with the regular gperf tool that is available in linux distributions . Added support for FC9 . Added support for OpenSuSE 11.0 . Improved support for GCC 4.2 and 4.3 . Added support for CodeGear C++ Builder 2009 USER VISIBLE CHANGES BETWEEN ACE-5.6.4 and ACE-5.6.5 ==================================================== . Added new Monitoring lib that can be used to store and retrieve counters. This is disabled by default because it is not 100% finished yet, with the next release it will be enabled by default . Fixed bug in ACE_Service_Config when it was used from a thread not spawned by ACE . Add VxWorks 6.x kernel mode with shared library support to ACE . Extended the implementation of Unbounded_Set, which has been renamed Unbounded_Set_Ex, to accept a second parameter which is a comparator that implements operator() which returns true if the items are equivalent. Unbounded_Set has been reimplemented in terms of Unbounded_Set_Ex using a comparator that uses operator==, which captures the previous behavior. . Added support for Intel C++ on MacOSX USER VISIBLE CHANGES BETWEEN ACE-5.6.3 and ACE-5.6.4 ==================================================== . Reworked the relationship between ACE_Service_Config and ACE_Service_Gestalt . Improved autoconf support . Improved AIX with gcc support . Improved OpenVMS support . Improved VxWorks support USER VISIBLE CHANGES BETWEEN ACE-5.6.2 and ACE-5.6.3 ==================================================== . Deprecated Visual Age 5 and older . Closed a rare race condition hole whereby ACE_Atomic_Op<> function pointers would not be fully initialized prior to use. See bugzilla 3185 for details. . Tweaks to support MacOS X Leopard (10.5 and 10.5.1) on Intel . Fixed compile problems with MinGW with GCC 4.2. Do note that we do see much more test failures then when using GCC 3.4. . Changed to use synchronous exception handling with msvc 8/9 which is the default. Asynchrous exception handling does catch access violations but it leads to lower performance and other problems. See also bugzilla 3169 . Make ace_main extern C with VxWorks so that it doesn't get mangled . Fixed compile errors and warnings for VxWorks 6.6 . Added an MPC generator for the WindRiver Workbench 2.6 which is shipped with VxWorks 6.4 . Added support for CodeGear C++ Builder 2007 with December 2007 update installed . Added support for VxWorks 5.5.1 . Implemented the const reverse iterator for ACE_Hash_Map_Manager_Ex . Increased support for using ACE_Hash_Map_Manager_Ex with STL functions based on latest standard C++ draft USER VISIBLE CHANGES BETWEEN ACE-5.6.1 and ACE-5.6.2 ==================================================== . ACE-ified the UUID class, which will change user applications slightly. . Added support for Sun Studio 12 . Added support for Intel C++ 10.1 . Fixed runtime problems with VxWorks 6.x in kernel mode, several improvements have been made to ACE, but also some problems in the VxWorks kernel have been found for which WindRiver has made patches. . Added support for VxWorks 6.5 kernel mode . Added support for MacOS 10.5 . Support for MacOS 10.4 is now deprecated. . Added support for OpenSuSE 10.3 . Added support for RedHat 5.1 . Added support for Microsoft Visual Studio 2008 . Added support for Fedora Core 8 . Added support for Ubuntu 7.10 . With Ubuntu 7.04 and 7.10 we can't use visibility, that results in unresolved externals when building some tests. With lsb_release we now detect Ubuntu 7.04 and 7.10 automatically and then we disable visibility . Removed deprecated (un)subscribe methods from ACE_SOCK_Dgram_Mcast . Added an additional replace() method to ACE_OuptutCDR for replacing a ACE_CDR::Short value. Also added write_long_placeholder() and write_short_placeholder() to properly align the stream's write pointer, write a placeholder value and return the placeholder's pointer. The pointer can later be used in a call to replace() to replace the placeholder with a different value. . Initial support for VxWorks 6.6 . Removed support for pthread draft 4, 6, & 7. This makes the ACE threading code much cleaner . Improved autoconf support . Fixed TSS emulation problems . Changed ACE_thread_t and ACE_hthread_t to int for VxWorks kernel mode. All thread creation methods do have an additional const char* argument to specify the task name, this now also works with pthread support enabled . Use bool in much more interfaces where this is possible . Added support for Debian Etch . Fixed ACE CDR LongDouble support on VxWorks 6.x . Added Microsoft Visual Studio 2008 project files to the release packages . Fixed a few bugs in the ACE_Vector template USER VISIBLE CHANGES BETWEEN ACE-5.6 and ACE-5.6.1 ==================================================== . Added support for CodeGear RAD Studio 2007 . Added support for CodeGear C++ Builder 2007 Update 3 . Modified the definiton of ACE_DEFAULT_THREAD_KEYS on Windows so it is based on the version of the OS as defined by Microsoft in this web page: http://tinyurl.com/2jqcmd This fixes bugzilla #2753 USER VISIBLE CHANGES BETWEEN ACE-5.5.10 and ACE-5.6 ==================================================== . OpenVMS 8.3 on IA64 port . Added autoconf support for Intel C++ 10.0 . Improved autoconf support on Linux, Solaris, NetBSD and HPUX . CodeGear C++ Builder 2007 Update 2 support . The netsvcs's client logging daemon has a new configuration option, -llocal-ip[:local-port], which can be used to specify the local IP address and port number for the client logging daemon's connection to the server logging daemon. If the -l option is specified with an IP address but not a port number, an unused port number is selected. . A new ACE+TAO port to LabVIEW RT 8.2 with Pharlap ETS. The host build environment is Windows with Microsoft Visual Studio .NET 2003 (VC7.1). Please see the ACE-INSTALL.html file for build instructions. USER VISIBLE CHANGES BETWEEN ACE-5.5.9 and ACE-5.5.10 ==================================================== . The ACE_utsname struct, used in the ACE_OS::uname() function when the platform doesn't provide the standard utsname struct, was changed. It defines a number of text fields and their types were changed from ACE_TCHAR[] to char[] in order to be consistent with all other platforms. This removes the need to write different code for platforms where ACE_LACKS_UTSNAME_T is set and that have wide characters (most probably Windows). Fixes Bugzilla #2665. . The ACE::daemonize() "close_all_handles" parameter was changed from an "int" to a "bool" to better reflect how it is used. . VxWorks 6.5 support. Compilation of the core libraries has been validated but no runtime testing has been performed. . CodeGear C++ Builder 2007 support. . The FaCE utility was moved from the ACE_wrappers/apps directory to ACE_wrappers/contrib. It is used for testing ACE+TAO apps on WinCE. See the ACE_wrappers/contrib/FaCE/README file for more information. . ACE_INET_Addr::set (u_short port, char *host_name, ...) now favors IPv6 addresses when compiled with ACE_HAS_IPV6 defined and the supplied address family is AF_UNSPEC. This means that if host_name has an IPv6 address in DNS or /etc/hosts, that will be used over an IPv4 address. If no IPv6 address exists for host_name, then its IPv4 address will be used. . Intel C++ 10.0 support . Support for the version of vc8 for 64-bit (AMD64) shipped with the Microsoft Platform SDK. . Fixed ACE_Vector::swap() (bugzilla #2951). . Make use of the Atomic_Op optimizations on Intel EM64T processors. The Atomic_Op is now several times faster on EM64T then with previous versions of ACE USER VISIBLE CHANGES BETWEEN ACE-5.5.8 and ACE-5.5.9 ==================================================== . Use Intel C++ specific optimizations for Linux on IA64 . Improved support for ACE_OS::fgetc. Added support for ACE_OS::fputc, ACE_OS::getc, ACE_OS::putc and ACE_OS::ungetc. . Added support for ACE_OS::log2(double) and improved support for ACE::log2(u_long). . Shared library builds on AIX now produce a libxxx.so file instead of the previous practice of producing libxxx.a(shr.o). . GCC 4.1.2 that comes with Fedora 7 seems to have a fix for the visibility attribute we use for the singletons. F7 users will therefore need to define the following in your config.h file. ACE_GCC_HAS_TEMPLATE_INSTANTIATION_VISIBILITY_ATTRS 1 . Fixed (rare) problem in TP_Reactor where incorrect event handler was resumed. . Reduced footprint on some platforms, particularly those that use g++ >= 3.3. USER VISIBLE CHANGES BETWEEN ACE-5.5.7 and ACE-5.5.8 ==================================================== . Extended ACE_Event constructor with optional LPSECURITY_ATTRIBUTES argument . Added support for QT4 . Added support to integrate with the FOX Toolkit (www.fox-toolkit.org) . Added support for Microsoft Visual Studio Code Name "Orcas", which is the msvc9 beta . Added ability to provide an optional priority when calling ACE_Message_Queue_Ex::enqueue_prio(). There was previously no way to specify a priority for queueing. . Removed support for Visual Age on Windows. . ACE will compile once again with ACE_LACKS_CDR_ALIGNMENT #defined. . ACE_Process_Manager::terminate() no longer removes the process from the process descriptor table; the pid remains available in order to call ACE_Process_Manager::wait(). USER VISIBLE CHANGES BETWEEN ACE-5.5.6 and ACE-5.5.7 ==================================================== . ACE 5.5 contained a set of pragmas which prevented Visual Studio 2005 (VC8) from issuing warnings where C run-time functions are used but a more secure alternative is available. For more information on the C run-time issues and Microsoft's response, please see the following MSDN page: http://msdn2.microsoft.com/en-us/library/8ef0s5kh(VS.80).aspx. In this beta, the pragmas which prevented the warnings have been removed. The ACE library has been reviewed and most of the use of "unsafe" functions has been fixed where possible. Since not all of the warnings emanating from ACE are situations that can or should be fixed, the ACE VC8 projects will prevent the warnings while building the ACE kit and its contained examples, tests, etc. The warnings are disabled by adding Microsoft-specified macros to the compile line via MPC. If desired, the warnings can be re-enabled by regenerating the project files with different MPC features. Note, however, that while ACE without warnings caused by the new C run-time functions, your application builds may trigger these warnings either by use of the "unsafe" C run-time functions or via use of an inlined ACE_OS method which uses it. If the warning is caused by an ACE_OS method, there is a more safe alternate available, probably located by appending _r to the method name (e.g., instead of using ACE_OS::ctime(), use ACE_OS::ctime_r()). There are other cases where the compiler may have issued warnings and ACE prevented this via a #pragma. These #pragmas have been removed as well. This may cause your application builds to trigger more warnings from VC8 than past ACE versions. You should review your code and either correct the code or disable the warnings locally, as appropriate. . The "release" argument to a number of ACE_String_Base<> methods was changed from int to bool to more accurately reflect its purpose. The following methods were changed: ACE_String_Base (const CHAR *s, ACE_Allocator *the_allocator = 0, int release = 1); to ACE_String_Base (const CHAR *s, ACE_Allocator *the_allocator = 0, bool release = true); ACE_String_Base (const CHAR *s, size_type len, ACE_Allocator *the_allocator = 0, int release = 1); to ACE_String_Base (const CHAR *s, size_type len, ACE_Allocator *the_allocator = 0, bool release = true); void set (const CHAR * s, int release = 1); to void set (const CHAR * s, bool release = true); void set (const CHAR * s, size_type len, int release); to void set (const CHAR * s, size_type len, bool release); void clear (int release = 0); to void clear (bool release = false); Since ACE_String_Base forms the basis of the ACE_CString and ACE_TString classes, this may ripple out to user application code. If you encounter errors in this area while building your applications, replace the int argument you are passing to the method now with either true or false. . Solutions for the eVC3/4 platform have been removed from this release. Note that we package WinCE projects/workspaces for use with VC8. . There were 3 new ACE_Log_Msg logging format specifiers added to make logging easier for types that may change sizes across platforms. These all take one argument, and the new formats are: %b - format a ssize_t value %B - format a size_t value %: - format a time_t value . The ace/Time_Request_Reply.h and ace/Time_Request_Reply.cpp files were moved from $ACE_ROOT/ace to $ACE_ROOT/netsvcs/lib. The time arguments in the public API to ACE_Time_Request were changed from ACE_UINT32 to time_t and the portions of the on-wire protocol that contains time was changed from ACE_UINT32 to ACE_UINT64. Thus, code that uses the ACE_Time_Request class to transfer time information will not interoperate properly with prior ACE versions. This will affect uses of the netsvcs time clerk/server. . The portion of the ACE_Name_Request class that carries the on-wire seconds portion of a timeout value was changed from ACE_UINT32 to ACE_UINT64. This means that Name server/clients at ACE 5.5.7 and higher will not interoperate properly with previous ACE versions' name servers/clients. . In the ACE_Log_Record (ACE_Log_Priority, long, long) constructor, the second argument, long time_stamp, was changed to be of type time_t. This aligns the type with the expected value, a time stamp such as that returned from ACE_OS::time(). . Added support for VxWorks 6.x cross compilation using a Windows host system . Added support for VxWorks 6.x using the diab compiler . The destructor of ACE_Event_Handler no longer calls purge_pending_notifications(). Please see bugzilla #2845 for the full rationale. (http://deuce.doc.wustl.edu/bugzilla/show_bug.cgi?id=2845) USER VISIBLE CHANGES BETWEEN ACE-5.5.5 and ACE-5.5.6 ==================================================== . The ACE_TYPENAME macro has been added to those that are not available when the ACE_LACKS_DEPRECATED_MACROS config option is set (it is not set by default). You are encouraged to replace the use of ACE_TYPENAME with the C++ typename keyword before the ACE_TYPENAME macros is removed from ACE in the future. . A new script, rm_exception_macros.pl, has been added to help users remove the use of the ACE exception macros from their own code. USER VISIBLE CHANGES BETWEEN ACE-5.5.4 and ACE-5.5.5 ==================================================== . The prebuild MPC keyword is now supported by the gnuace project type. This fixes Bugzilla #2713. . Support for Windows earlier than NT 4 SP2 was removed. ACE will not build for Windows 95, 98, Me, etc. out of the box any longer. . Reformat stringified IPv6 addresses to use [addr]:port when printing addresses that contain ':' such as "::1". . Added method to ACE_INET_Addr to determine if address is IPv6 or IPv4 multicast. . Fixed a bug in ACE_Async_Timer_Adapter_Timer_Queue_Adapter where the gettimeofday function of the timer queue was ignored when setting the alarm. . Fixed a problem where, on Solaris 9 onwards, calling ACE_OS::thr_create(THR_NEW_LWP) more than 2^15 (65535) times in a process will fail. See changelog entry from "Wed Jan 3 22:31:05 UTC 2007 Chris Cleeland " for more information. . Fixed a bug in ACE_QtReactor where the two select() calls in that function might select on different handler sets. . ACE_SOCK_IO::recvv(iovec[], size_t, const ACE_Time_Value* = 0) and ACE_SOCK_IO::sendv (const iovec[], size_t, const ACE_Time_Value* = 0) methods were changed to specify the iovec count argument as int instead of size_t since it gets reduced to int in the underlying OS calls (usually). . The following deprecated methods were removed: ssize_t ACE_SOCK_IO::recv (iovec iov[], size_t n, const ACE_Time_Value *timeout = 0) const; ssize_t ACE_SOCK_IO::recv (iovec *io_vec, const ACE_Time_Value *timeout = 0) const; ssize_t ACE_SOCK_IO::send (const iovec iov[], size_t n, const ACE_Time_Value *timeout = 0) const; These were previously replaced with more specific recvv() and sendv() methods. . The ACE_Service_Repository::find(const ACE_TCHAR name[], const ACE_Service_Type **srp = 0, int ignore_suspended = true) const method's 'ignore_suspended' parameter was changed from int to bool to reflect it's purpose as a yes/no indicator. . Added --enable-ace-reactor-notification-queue configure script option to the autoconf build for enabling the Reactor's userspace notification queue (defines ACE_HAS_REACTOR_NOTIFICATION_QUEUE in config.h). . The int ACE_OutputCDR::consolidate(void) method was contributed by Howard Finer at Sonus Networks. This method consolidates any continuation blocks used by an ACE_OutputCDR object into a single block. It's useful for situations which require access to a single memory area containing the encoded stream, regardless of its length, when the length cannot be known in advance. . There are a number of new methods defined on ACE_String_Base: size_t capacity (void) const: This method returns the number of allocated CHAR units in the string object. void fast_resize (size_t): This method manage the sizing/reallocating of the string, but doesn't do the memory setting of resize(). bool operator!= (const CHAR *) const bool operator== (const CHAR *) const: These methods compare the string with a nul-terminated CHAR* string. nonmember functions operator== and operator!= where also added that compare const ACE_String_Base and const CHAR*; these make it possible to switch ACE_String and CHAR* on either side of the operator. Thank you to Kelly Hickel for these additions. . There are 2 new build options on the traditional make command: dmalloc and mtrace. When specified at build time (e.g. make mtrace=1) the PLATFORM_DMALLOC_CPPFLAGS and/or PLATFORM_MTRACE_CPPFLAGS values are added to CPPFLAGS. For dmalloc, the PLATFORM_DMALLOC_LDFLAGS and PLATFORM_DMALLOC_LIBS are added to LDFLAGS and LIBS, respectively. Thank you to Howard Finer for supplying these additions. . Added the ability to specify additional purify and quantify command-line options by setting PLATFORM_PURIFY_OPTIONS and PLATFORM_QUANTIFY_OPTIONS, respectively. Thank you to Howard Finer for supplying these additions. . Added the ability to use trio (http://sourceforge.net/projects/ctrio/) if platform lacks decent support for vsnprintf. trio support is enabled by defining trio=1 in plaform_macros.GNU . Removed Irix 5, DGUX, and m88k support . Improved LynxOS 4.2 support . VxWorks 6.4 support . Added support for FC6. Because the GCC 4.1.1 version that gets shipped has a fix for the visibility attribute we use for the singletons you will need to define the following in your config.h file. This can't be done automatically because SuSE 10.2 gets shipped with GCC 4.1.2 but doesn't have the same fix ACE_GCC_HAS_TEMPLATE_INSTANTIATION_VISIBILITY_ATTRS 1 . RTEMS port USER VISIBLE CHANGES BETWEEN ACE-5.5.3 and ACE-5.5.4 ==================================================== . Added appropriate intptr_t and uintptr_t typedefs on platforms that don't provide them (i.e. when ACE_LACKS_INTPTR_T is defined). . Added ability to explicitly choose support for 32 bit or 64 bit file offsets on all platforms. Define the _FILE_OFFSET_BITS preprocessor symbol to either 32 or 64 to choose the desired number of file offset bits. This preprocessor symbol is supported natively by most UNIX and UNIX-like operating systems, and supported by ACE on Windows. Use the new ACE_OFF_T typedef to refer to file offsets across UNIX and Windows portably. . 64-bit file offsets are now enabled by default in Win64 configurations. . Improved support for 64 bit platforms (64 bit addresses, etc). . Added STL-style traits, iterators and a swap() method to the ACE_Array_Base<> class template. . Added STL-style traits and iterator accessors to the ACE_Hash_Map_Manager_Ex<> class template, as well as new find() and unbind() methods that return (as an "out" parameter) and accept iterators, respectively. . Greatly improved event handler dispatch performance in select()-based reactors (e.g. ACE_Select_Reactor and ACE_TP_Reactor) for large handle sets on Windows. Previous event handler search were linear, and are now constant on average. . Addressed a number of Coverity errors (CHECKED_RETURN, DEADCODE, LOCK, USE_AFTER_FREE, RESOURCE_LEAK, FORWARD_NULL). . Added STL-style "element_type" trait to all ACE auto_ptr class templates. . Removed support for LynxOS 3.x. . Resolved Bugzilla #2701 to ensure fini() is called for all Service Objects upon calling ACE_Service_Config::close() . VxWorks 5.5.2 has been tested, for ACE the support is exactly the same as for VxWorks 5.5.1. No specific defines or flags have to be used. USER VISIBLE CHANGES BETWEEN ACE-5.5.2 and ACE-5.5.3 ==================================================== . Added the base projects for executionmanager_stub and plan_generator. . Added the ACE_Hash_MultiMap_Manager class and its test file. . Changed the ACE_Synch_Options::operator[] method to return bool rather than int. The value returned is a yes/no indication of whether or not the specified option(s) are set in the object. . Changed the prototype(s) for ACE::debug () to return (and take) a bool. This is consistent with the original intent for this feature. If you have been using it like 'ACE::debug () > 0' or 'ACE::debug (1)', you may have to rebuild ACE. The value of the ACE_DEBUG environment variable can be used to specify the initial value for ACE::debug(), at the process start up. . An assembler (within a C source file) based implementation for SPARC of atomic operations suitable for use with the ACE_Atomic_Op and ACE_Atomic_Op specializations has been added. Currently, it can only be enabled by setting the atomic_ops_sparc make macro to 1 when using the GNUACE build system with the Solaris SunCC compiler. It should be noted that this requires the -xarch=v8plus (or higher) be added to the CFLAGS make macro or the assembler code will not compile. . The ACE_Message_Queue_Ex_N class is new, contributed by Guy Peleg . ACE_Message_Queue_Ex_N is similar to ACE_Message_Queue_Ex in that the object queued is a template parameter. However, ACE_Message_Queue_Ex_N allows the enqueueing and dequeueing of multiple chained objects at once. This wasn't added to ACE_Message_Queue_Ex because the chained object functionality requires the ACE_MESSAGE_TYPE class to have a ACE_MESSAGE_TYPE *next (void) const method, analogous to ACE_Message_Block::next(), to follow the chain and this would probably break existing applications using ACE_Message_Queue_Ex. The ACE_wrappers/tests/Message_Queue_Test_Ex.cpp test has an example of how to use the new class. . The selector and comparator function pointer arguments to ACE_OS::scandir() and ACE_Dirent_Selector are now marked as extern "C" to enforce their use with a C RTL function. User code that defines functions which are passed as the selector or comparator arguments which are not declared extern "C" may generate compile warnings. To resolve this, add extern "C" to the function's signature. See ACE_wrappers/tests/Dirent_Test.cpp for an example. . To address a problem in the ACE string interface that prevented substring or character searches in very large strings (e.g. greater than the maximum value of an ssize_t type) from being correctly reported to the caller, the find(), rfind() and strstr() methods now return an unsigned integer (size_t) instead of a signed one (ssize_t). Affected classes include: * ACE_CString * ACE_WString * ACE_TString * ACE_NS_WString Unless you have been explicitly using -1 instead of npos when comparing the return value of find(), rfind() and strstr(), and/or assigning the return value to ssize_t you should not see any difference. A new size_type typedef has been added to the ACE string class to aid developers. This typedef is analogous to the standard C++ string::size_type typedef. The ACE_String_Base<>::strstr() documentation and the default rfind() argument erroneously referred to -1 instead of npos. Those instances have been corrected. To summarize, a "no position" condition is denoted using the npos constant, not -1. It can be referred directly by scoping it with the appropriate string class (e.g. ACE_CString::npos, ACE_WString::npos, etc). . Changing the shared library extension for hpux ia64 to ".so". On HP-UX 11i Version 1.5 the naming scheme is lib*.sl for PA and lib*.so on IPF. . The ACE_Refcounted_Auto_Ptr reset() and release() methods were changed per Bugzilla #1925. They will both now detach from the underlying ACE_Refcounted_Auto_Ptr_Rep object; reset() will create a new one for the new pointer specified as its argument. This change may cause referenced objects to be deleted in cases where previous ACE versions would not have. . The return type of "ACE_Refcounted_Auto_Ptr::null (void) const" changed from int to bool. It's possible values, true and false, have not changed. . TTY_IO now accepts "none" as a valid parity value. Due to this change 'parityenb' member is now deprecated and will be removed in the future. The users of TTY_IO class should change their code to use only 'paritymode' member for parity control and leave 'parityenb' unchanged (it is enabled by default in class constructor). . Support for Intel C++ 9.1 on Windows and Linux . VxWorks 6.3 support . Fixed Bugzilla #2648 to make sure ACE_Service_Object::fini() is called iff ACE_Service_Object::init() succeeded, as per C++NPv2. . Added preliminary support for Mac OS X 10.4 on Intel CPU's. . Fixed Bugzilla #2602 to re-enable XML Service Configurator file support. USER VISIBLE CHANGES BETWEEN ACE-5.5.1 and ACE-5.5.2 ==================================================== . Added support for: - VxWorks 6.2 for the rtp model using pthread support - OpenVMS 8.2 for Alpha . Removed code and configurations that provided support for: - Visual C++ 6.0 and 7.0 - Chorus - pSOS - KAI C++ on all platforms . Explicit template instantiation support has been removed. This effectively removes support for Sun Forte 6 and 7 which required explicit template instantiation to build ACE reliably. . Added support for multiple independent Service Repositories through configuration contexts called "Gestalt". Full backwards compatibility is maintained through the existing ACE_Service_Config static methods, while direct individual repository access is enabled through instances of the new ACE_Service_Gestalt class. ACE_Service_Config has changed to a specialization of ACE_Service_Gestalt and is only responsible for the process-wide configuration. . To support dynamically-sized ACE_Log_Record messages, the netsvcs logging components now use ACE CDR encoding and transfer mechanisms inspired by the examples in Chapter 4 of the C++NPv1 book. The client and server logging daemons in ACE 5.5.2 and forward will not interoperate with those in previous ACE versions. . Added a wrapper for the sendfile API (ACE_OS::sendfile()). . Added support for netlink sockets on Linux. . Added a new method, ACE_Task::last_thread(). This method returns the thread ID (ACE_thread_t) of the last thread to exit from the ACE_Task object. Users checking to see if a thread is the last one out (for example, to know when to perform cleanup operations) should compare the current thread ID to the return value from last_thread(). This is a change from the previously recommended practice (C++NPv2, page 189) of comparing the return value of thr_count() with 0. . Changed the first argument to ACE_OS::strptime() to be 'const' which matches its usual usage in POSIX strptime(). This change allows users to pass const strings in - a common use case. . Made part of the file support in ACE 64bit but we have some places where 32bit types are used, this could lead to some conversion warnings which will be addressed in the near future, but getting everything 64bit compliant is a lot of work. USER VISIBLE CHANGES BETWEEN ACE-5.5 and ACE-5.5.1 ==================================================== . Added support for the --enable-symbol-visibility configure option to the autoconf build infrastructure instead of solely relying on feature tests to enable/disable symbol visibility support. This avoids build problems with icc, etc. . Added support for the --enable-fl-reactor configure option to the autoconf build infrastructure to build the ACE_FlReactor library. . Added support for the --enable-qt-reactor configure option to the autoconf build infrastructure to build the ACE_QtReactor library. . Added support for the --enable-xt-reactor configure option to the autoconf build infrastructure to build the ACE_XtReactor library. . Fixed a bug that would cause timer IDs from ACE_Timer_Heap to be improperly duplicated under certain conditions (Bugzilla #2447). . Fixed ACE_SSL_Context::private_key(), context(), and dh_params() methods to allow retrying a file load after a failed call. . Fixed ACE_SSL_Asynch_Stream so it can be instantiated; also moved the declarations for ACE_SSL_Asynch_Read_Stream_Result, ACE_SSL_Asynch_Write_Stream_Result, and ACE_SSL_Asynch_Result classes to the ace/SSL/SSL_Asynch_Stream.h file so applications can see them. USER VISIBLE CHANGES BETWEEN ACE-5.4.10 and ACE-5.5 ==================================================== . Added a platform macros option "templates=manual", currently only applies to AIX 5.3 with XL 7 compiler. It allows the user to tell the compiler to set -qnotempinc and -qnotemplateregistry and works well in static builds. . ACE and its tests compile error free with GCC 4.1 pre release. . ACE_Recursive_Thread_Mutex::get_nesting_level() fixed for 64-bit Windows XP on amd64/EM64T hardware. . Many build-time fixes for Windows Mobile 5 and Windows PocketPC 2003 using Visual Studio .NET 2005 (VC8). . Added support for the --enable-tk-reactor configure option to the autoconf build infrastructure to build the ACE_TkReactor library. USER VISIBLE CHANGES BETWEEN ACE-5.4.9 and ACE-5.4.10 ==================================================== . Fixed a bug in ACE_Timer_Heap_T::cancel(). . Improved ACE_Time_Value support for boundary conditions. . Fixed problems with operator placement delete on certain C++ compilers. . Fixed a bug with the ACE_SPIPE_Acceptor on Windows. . Correctly set sockaddr_in.sin_len and sockaddr_in6.sin6_len on platforms that have these fields. . Avoided problems with namespace pollution for max() macros. . Many fixes for ACE_LACKS* and ACE_HAS* macros for autoconfig. USER VISIBLE CHANGES BETWEEN ACE-5.4.8 and ACE-5.4.9 ==================================================== . Added dozens of new ACE_LACKS and ACE_HAS defines which are used to simplify the ACE_OS layer . Constructors of ACE_Time_Value have been made explicit to prevent implicit conversions. . Added a shutdown() method to ACE_Barrier. The new method aborts the wait by all threads. . Changed the behavior of ACE_Message_Queue::enqueue_head() and enqueue_tail(). If the enqueued message block has other blocks chained to it via its next() pointer, the entire chain of blocks will be enqueued at once. . Improved the support for high-resolution timers with ACE_Timer_Queue_Adapter. . Make it possible to disable file caching in JAWS. . Improved ACE_Pipe implementation so that it uses localhost to avoid firewall problems. . Added Unicode support to the Service Configurator. USER VISIBLE CHANGES BETWEEN ACE-5.4.7 and ACE-5.4.8 ==================================================== . Improved IPv6 support . Improved 64bit portability . TTY_IO overhaul - Improved documentation. - It is now possible to request infinite timeout in portable manner. This can be achieved by setting negative value to readtimeoutmsec. - Various bugs fixed and portability issues resolved. . Subset ACE for TAO and TAO Services . Support for Intel C++ 9.0 on Windows and Linux . Support for Microsoft Visual Studio 2005 (aka VC8) for Win32 as well as the Windows CE platforms Pocket PC 2003 and Windows Mobile 5. Solution/project files are generated with an appended "_vc8" for Win32 and "_WinCE" for the CE platforms. See ACE_wrappers/docs/CE-status.txt for more information. . Completed implementation of ACE_Dev_Poll_Reactor using the Linux epoll facility; tested on Red Hat Enterprise Linux 4. . The in-memory size of an ACE_RB_Tree will be smaller due to rearranged placement of pointers. . Added an optimization to CDR stream to ignores alignment when marshaling data. Use this new ACE_LACKS_CDR_ALIGNMENT compile-time option only when the ACE_DISABLE_SWAP_ON_READ macro is enabled. This new option requires ACE CDR engine to do both marshaling and demarshaling, and when this option is enabled the encoded streams are no longer compliant with the CORBA CDR specification. . Developed Feature Oriented Customizer (FOCUS) tool to enable specialization of middleware frameworks such as Reactor and Protocol framework. FOCUS provides an XML based transformation engine, where the transformations to specialize the components are captured in XML file and a weaver specializes the code. . Added support for unrolling ACE_OS::memcpy copy loop where applicable to improve performance. Autoconf tests empirically determine whether loop unrolling is at least 10% better than default version. . Added support for an ACE "versioned" namespace. When enabled, ACE library sources will be placed within a namespace of the user's choice or a namespace of the form ACE_5_4_7 by default, where "5_4_7" is the ACE major, minor and beta versions. The default may be overridden by defining the ACE_VERSIONED_NAMESPACE_NAME preprocessor symbol. Enable overall versioned namespace support by adding "versioned_namespace=1" to your MPC default.features file. USER VISIBLE CHANGES BETWEEN ACE-5.4.6 and ACE-5.4.7 ==================================================== . Support for shared libraries with VxWorks . Support for Solaris 10 on x86 with Sun Studio 10 (C++ 5.7). . Extended ACE_OS::event_xxx implementation to support platforms having either PThread support with Process Shared condition variables or POSIX semaphores with named (process shared) semaphore support or using the new FIFO based semaphores. . ACE_OS::closesocket() no longer calls ACE_OS::shutdown() on any platform while closing the socket. It previously called ACE_OS::shutdown() on HP-UX. Removing this call fixes the fork-and-close programming paradigm that's common to many networked applications. . RMCast - Support for message fragmentation. This will allow for messages larger than 64K. - Support for flow control. - Timed recv() in RMCast::Socket. - Per-instance configurable protocol parameters (e.g., message retention time, NAK timeout, etc). USER VISIBLE CHANGES BETWEEN ACE-5.4.5 and ACE-5.4.6 ==================================================== . Updated RMCast to include - Reactor-compatible interface. - Message unavailability reporting. - Protocol documentation. . Added support for 64bit Visual Age on AIX . Improved g++ 4.0 support. A number of RTTI related problems have been fixed. . Smaller footprint. . Fixed memory leaks ACE_DLL and ACE_Log_Msg classes. . The ACE::ICMP_Socket and ACE::Ping_Socket classes were moved out of the ACE namespace and "flattened" to ACE_ICMP_Socket and ACE_Ping_Socket to be consistent with the rest of ACE. . ACE_INET_Addr::set_address() - fixed a possible struct member alignment issue when building an IPv4-mapped IPv6 address. . Added a new ACE::wild_match() function to match a string based on wildcards. . Added efficient overloads for string concatenation to the ACE_String_Base class. . Added support for the use of pthread_getschedparam on MacOS X. . Fixed an issue with static initialization of TSS related classes on static builds for Windows. USER VISIBLE CHANGES BETWEEN ACE-5.4.4 and ACE-5.4.5 ==================================================== . Remove special handling in the Thread Specific Storage(TSS) code that released the TSS key for ACE_TSS. ACE_TSS has been changed to explicitly free the TSS key when necessary. . On Win32 systems: detect thread termination via a hook in DLLMain for ACE.dll. This allows cleanup of TSS objects for non-ACE threads that use ACE functions. The most common case was threads that used ACE logging. Formerly any TSS objects created by these threads would be leaked. . Added support for GNU G++ 4.0. The x.4.5 beta takes advantage of g++ 4.0's symbol visibility. This feature is conceptually similar to MS Windows "__declspec(dllexport)" DLL functionality. Using this new g++ feature results in substantially improved ACE/TAO/CIAO shared library binaries. A subset of the improvements include the following: * The number of unnecessarily exported DSO/DLL symbols is greatly reduced, resulting in faster program start times. * Smaller footprint. * Improved performance since run-time indirection of internal symbols is no longer needed. No changes to the ACE/TAO sources were necessary to support this feature since the required visibility attributes were hidden behind the various "*_Export" macros (formerly only useful for MS Windows DLLs) used throughout ACE/TAO. . The ACE_Reactor destructor will now call close() on the referenced reactor implementation. This assures that all handlers are notified before the ACE_Reactor object that's most likely referenced in these handlers is invalid. Although this should not be a user-visible change, it did catch some ACE tests off guard destroying reactor implementations and ACE_Reactor interfaces in the wrong order, so it may come up in the field as well. When using dynamically allocated reactor implementations, do not destroy the implementation object before the ACE_Reactor interface object. Use of the ACE_Reactor constructor's delete_implementation argument (with a value of 1) is recommended when dynamically allocating reactor implementations. . Improved performance of HTBP by not requiring a lookup of peer hostname. . Added new ACE_SizeCDR stream which allows one to calculate size of the representation without writing anything. . Number of improvements in RMCast, reliable multicast implementation. USER VISIBLE CHANGES BETWEEN ACE-5.4.3 and ACE-5.4.4 ==================================================== . The ace-config script has been replaced by pkg-config metadata files which are installed in ${prefix}/lib/pkgconfig by the automake build. . Remove ACE_OS::gets() implementation. While this ACE implementation of gets() did not contain the security holes that all standard gets() implementations have, keeping it around only serves to foster confusion since (1) some may incorrectly assume that this ACE-specific gets() implementation has the same holes as standard ones, and (2) invoking it with a default size argument so that it looks like a standard gets() call results in behavior that is different from the standard. Use ACE_OS::fgets() instead. . Removed ACE_Unbounded_Set_Ex, this gave the false idea that it had thread safe iterators. Use ACE_Unbounded_Set instead . Improved VxWorks support for static libraries. Shared libraries do cause several known problems which will be fixed in the x.4.5 release. . Removed the usage of the ACE_x_cast macros, we are using the C++ casts from now on. The ACE_x_cast macros are deprecated and will be removed after the x.5.1 release . Some improvements in autoconf support; better detection of available OS and compiler features. . Fixed bugs in ACE TSS emulation USER VISIBLE CHANGES BETWEEN ACE-5.4.2 and ACE-5.4.3 ==================================================== . Improved Cygwin 1.5.12 support, 90% of the tests now succeed . Improved OpenVMS support. . Added ability to use fltk with Cygwin/MinGW . Added ACE_INT64 that defines a native 64 bit type. . Added 'q' as usable specifier for ACE_Log_Msg to print out int64 bit number. . Added better support for Intel C++ compilers. . Improved HPUX support. . Added a new directory ("ACE_wrappers/protocols/ace") for new protocols that are not directly components of ACE, but are relate to ACE and defined a new protocol, HTBP (Hypertext Tunneling, Bidirectional Protocol) providing ACE_Acceptor/Connector/Stream semantics over a connection owned by an HTTP proxy. Test cases in ACE_wrappers/tests/HTBP provide examples of use. . Performace enhancement in TP_Reactor's handle_timer_events method [Bug 1971]. . Various changes to permit ACE to execute on HP NonStop platform (e.g support for its pthreads version). . Updated HP NonStop configuration files (config-tandem-nsk). . The "ACE" pseudo-namespace is now a true C++ namespace. Transitional pseudo-namespaces that were only meant to be used internally by ACE, such as "ACE_Sock_Connect", no longer exist. . ACE_CDR::Boolean type is now a true C++ "bool" on all platforms except MSVC++ 6. We plan to deprecate MSVC++ 6 support sometime after the x.5 release of ACE+TAO+CIAO, so we recommend you start migrating to a later version of MSVC++. . More GNU g++ 3.4.x fixes. . Added ICMP and "ping" socket support. . Added mkstemp() emulation. . Fixed problem on Linux < 2.5.47 platforms where equality comparison of two logically equal sockaddr_in structure instances would incorrectly fail. . Support for wide characters has been improved on non-Windows platforms. . A number of Windows CE problems have been fixed. . ACE's loading of DLLs (for example, as a result of loading synamic services) has been changed to use the native OS's facilities for locating the DLL instead of searching LD_LIBRARY_PATH (or its equivalent) then loading the DLL using a full pathname. This restores enforcement of a platform's loading and security policy. To use the old DLL locating method, add ACE_MUST_HELP_DLOPEN_SEARCH_PATH to your config.h file before building ACE. . A number of errors in the APG example programs have been corrected. . Select_Reactor and Priority_Reactor performance improved. [Bug 1890] . Wide-char functionality on POSIX (Linux, etc.) . TSS memory leak fixes [Bug 1542] . Ported to HPUX 11i v2 on Itanium . Added code to ACE for platform RedHat AS 3.0 on Opteron. . Changed ACE::crc32() family of functions to NOT fold in the length of the string/buffer/iovec into the CRC. USER VISIBLE CHANGES BETWEEN ACE-5.4.1 and ACE-5.4.2 ==================================================== . Support for g++ 3.4.1. . All ACE Makefiles, project files, etc, are now generated by OCI's "MakeProjectCreator" (MPC) tool. Makefiles and project files for commonly used configurations have been pre-generated and distributed with the beta(s). Please see: $ACE_ROOT/ACE-INSTALL.html for information on how to use MPC with ACE. . Improved Doxygen documentation. . Reduced header file dependencies, which should speedup compilation and help minimize static footprint. . ACE now requires support for the following standard C++ features: - "bool" keyword - "mutable" keyword - "explicit" keyword - C++ casts (e.g. static_cast<>, reinterpret_cast<>, dynamic_cast<> and const_cast<>) If you're using a compiler that does NOT support these features please contact Steve Huston for support. . Changed the select()-based reactor implementations to scan for broken handles to remove based on the registered handles, not on event handlers. This allows for bad handles to be removed from the reactor even if the event handler doesn't implement get_handle() the way we expect. . Support for Pthreads native recursive mutexes was added. This capability is specified to ACE_OS::mutex_init() as an optional argument, lock_type. To fix confusion from an earlier attempt to add this functionality, the meaning of the old 'type' argument to ACE_OS::thread_mutex_init() is changed. It previously combined the scope and type. Now it is just the type (e.g. recursive), as the scope is inherent in the method used. For clarification on ACE_HAS_RECURSIVE_MUTEXES, it means that the platform is capable of them, not that they always are, as one would expect. However, before Pthreads had recursion added, it was never optional. Now it is. . Initial support for new Linux sys_epoll() interface in Dev_Poll_Reactor. The obsolete Linux /dev/epoll interface is no longer supported. . Improved Cygwin support. - Threading works without problems. - Problems with shared memory, process shared mutexes, multicast and some other small things still exist. . New OpenVMS port. - This is for the latest version of OpenVMS with all available ECOs applied. Basic stuff works without problems. Advanced features still need some work. . Usage of ASYS_INLINE is deprecated in ACE. Use ACE_INLINE instead. . All inline source files now end in ".inl". The previous ".i" extension is generally used for preprocessed C sources. . Autoconf support has been improved and fixed on a number of platforms, including the BSD variants (e.g. FreeBSD). It is still not the preferred way to configure most platforms, but it is ready for wider testing. Please report any problems found to ace-bugs@cs.wustl.edu. . A number of fixes were made to quiet compile errors and warnings on 64-bit Windows. . For builds on AIX using Visual Age C++, the make rtti option default was changed to 1, enabling RTTI by default. . ACE_Service_Repository::remove() has a new, optional argument that can receive the service record pointer for the removed service. If the pointer is returned to the caller, it is not deleted. If the pointer is not returned to the caller (the default) it is deleted (this is the historic behavior). . The tutorials in ACE_wrappers/docs have been removed. They were not being maintained and caused confusion in a number of cases. Now that there are complete examples that match the printed books (C++NPv1, C++NPv2, APG), the older tutorials are no longer useful. Please see $ACE_ROOT/examples/C++NPv1/ $ACE_ROOT/examples/C++NPv2/ $ACE_ROOT/examples/APG/ for the source code of the examples in those books. . ACE_String_Base::fast_clear() is a new method which sets the string length to 0. Doesn't release string-allocated memory, but if the memory was externally supplied, it is no longer referenced from the string object. . A true C++ "bool" is now used as the CDR stream boolean type, if supported by the compiler. . Renamed AIX 5L configuration header from config-aix5.1.h to config-aix-5.x.h. . All C++ equality, relational and logical operators now return bool instead of int, as is the norm for modern C++. . Added new ACE_OS::realpath() implementation. Contributed by Olli Savia USER VISIBLE CHANGES BETWEEN ACE-5.4 and ACE-5.4.1 ==================================================== ACE --- . Fixed "make install" support in ACE+autoconf configurations. . Fixed autoconf support on Solaris. . Corrected invalid `aux' directory (on MS Windows) found in ACE distribution. . ACE/TAO build now without problems with MinGW and all ACE tests run now without problems . Added some more support for the new CBuilderX Preview compiler, this is not 100% ready yet because the compiler is still a preview and has its own problems. . Added Visual SlickEdit 8.1 MPC template . Added workaround for compile problems in Borland Release builds . Cygwin 1.5.9 is now supported . Tests for IPV6 have been added . Implement lstat() so that it'll use stat() on platforms that don't support lstat(). . Problems related to ACE_Event_Handler usage in WFMO_Reactor was fixed. . A wrapper for rmdir () has been added. . Threads spawned in thread-per-connection mode never inherited the priority. This problem was fixed and this fix is consistent with the C++ NPV* books. . Fixed memory leaks with ACE_String_Base::resize () . Enable the usage of native recursive mutexes for the implementation of ACE recursive mutexes on Linux. . The ACE Proactor framework can now be enabled for AIX 5.2. Since AIO functionality is not run-time enabled by default on AIX 5.2, the ACE Proactor code is not built by default on AIX. To enable it, the config.h file must contain #define ACE_HAS_AIO_CALLS before including the config-aix-5.1.h file. . The ACE_POSIX_CB_Proactor implementation is now built on all platforms except LynxOS. USER VISIBLE CHANGES BETWEEN ACE-5.3.6 and ACE-5.4 ================================================== ACE: --- . Added a new makefile commandline flag, static_link, that can be used to force static linking when static_libs_only is turned on. It uses the new STATIC_LINK_FLAG variable and is currently only implemented for for GNU ld, i.e., it adds the "-static" option to LDFLAGS. It's turned off by default since using it causes the footprint to go up by almost 1 MB on Linux, since it links all the system and compiler .a files, but can be turned on if users want/need to use it, by enabling both static_libs_only and static_link. . Added macros ACE_USES_GPROF which enables users to use gprof in a multithreaded environment with ACE libs. . Added a new functor template class, ACE_Malloc_Lock_Adapter_T, that's used by ACE_Malloc_T as a factory for the ACE_LOCK template parameter, and allows the use of locking strategy classes, like ACE_Process_Semaphore and ACE_Thread_Semaphore that don't have a satisfactory ctor taking a single required ACE_TCHAR* parameter, to be adapted to work with ACE_Malloc_T. . The source code examples from "The ACE Programmer's Guide" book by Huston, Syyid, and Johnston, are now located in $ACE_ROOT/examples/APG. . Support for GNU autoconf is now in ACE. Please see ACE-INSTALL.html for details. . Fixed problems that prevented ACE from being compiled on LynxOS 4.0.0. . Fixed compilation error which prevented ACE from being compiled when ACE_COMPILE_TIMEPROBES was set to 1. . Preliminary support for Tandem NSK has been added. . Lots of bug fixes with TLI and XPG5. Please see $ACE_ROOT/ChangeLog for details. . Fixed ACE_OS::event_timedwait() and ACE_OS::event_wait() so that they use a while loop around the ACE_OS::cond_[timed]wait() calls to avoid problems with spurious wakeups, etc. . ACE's wrapper around getipnodebyname() and getipnodebyaddr () has been made go through the IPv4-only case on ACE_WIN32. Since Windows IPv6 implementation doesn't offer support (at thistime) for getipnodebyname() the code has been changed to use the IPV4 part of the code. . Install with Borland C++ of ACE library fixed ACEXML: ------- . Fixed memory leak in ACEXML parser. . Fixed implementations of rewind() in all the CharStreams. They were broken previously. . Fixed bugs in the parser associated with incorrect handling of PE References for keywords.
