(Remedy) VxWorks 6.2 support - -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<TYPE>. ACE_TSS<TYPE> 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 <shuston@riverace.com> 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 <ops at iki dot fi> - - -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. |
