There are two new ACE_Time_Value methods for getting and setting millisecond + values to/from ACE_UINT64 values: + + ACE_UINT64 ACE_Time_Value::get_msec () const + void ACE_Time_Value::set_msec (const ACE_UINT64 &ms) + + The former is a replacement for the existing msec(ACE_UINT64&) methods that + are "getter" methods whose signatures look confusingly like "setters". See + Bugzilla #3336 for the history behind this change. + + The latter is for consistency and clarity. + +. Added ACE INet addon library for Inet protocol clients (and possibly + servers at some point) like http://, ftp:// etc. + The library implements standard C++ iostream wrapper classes for + ACE Svc_Handler and Reactor based input/output handling, URL classes + and protocol handler classes. + NOTE: This is work in progress! There is no guarentee that the API + won't change in the next few releases. + Protocol handling is currently restricted to client side download + requests for HTTP and FTP. + Handling for upload requests should be added in the near future as well + as HTTP Basic Authentication. + +USER VISIBLE CHANGES BETWEEN ACE-5.7.8 and ACE-5.7.9 +==================================================== + +. ACE's default makefiles (traditional ACE/GNU, not autoconf/automake) + now support installation with "make install". + Please see the ACE-INSTALL.html file for instructions. + +. Support for the ARCH make variable has been enhanced to apply to executables + (in addition to libraries and object files), and the ARCH feature has been + integrated into the MPC-generated makefiles (to work with MPC's requires + and avoids features). + +USER VISIBLE CHANGES BETWEEN ACE-5.7.7 and ACE-5.7.8 +==================================================== + +. ACE now uses GCC builtin Atomic instructions for short, + unsigned short, long, unsigned long, int, unsigned int, + and bool. This makes our Atomic_Op around 7 times faster + +. ACE Service Configuration Framework now process first service + configuration files and then command-line directives. Thus if + application uses both service configuration files and command-line + directives then the command-line directives may override results of + directives in the configuration files. At the same time if the + application uses only the default svc.conf file and command-line + directives then the directives from svc.conf can not override + results of the user provided command-line directives. + +. ACE_Dev_Poll_Reactor now dispatches notifications in only one thread at + a time. This brings notification handling more in line with behavior in + other Reactor implementations. + +USER VISIBLE CHANGES BETWEEN ACE-5.7.6 and ACE-5.7.7 +==================================================== + +. Integrated fix for bug 3104 and regression test for + interval timers. + +. Added support for GCC builtin Atomic instructions which + are enabled with GCC >= 4.1 for PPC32/PPC64/IA64 + +. Improved autoconf support for debian + +. Added support for -mcpu and -mtune. Add TCPU=.. to your + environment/platform_macros.GNU to specify you cpu and + than add cpumodelflag=1 and/or tunemodelflag=1. Using + this with IBM Cell increased the performance significantly + +USER VISIBLE CHANGES BETWEEN ACE-5.7.5 and ACE-5.7.6 +==================================================== + +. Added support for iPhone/iPod Touch/iPad. The following + environment variables are needed: + + IPHONE_TARGET, should be set to either SIMULATOR or + HARDWARE. Set to HARDWARE if you want to deploy + on the iPhone/iPod Touch/iPad device. + + IPHONE_VERSION, should be set to 3.1.2 or 3.2. One can + set the version to any future or past versions, but + only 3.1.2 and 3.2 have been tried. + + Note that one has to compile ACE/TAO statically as + it is believed that the iPhone OS does not support + dynamic loading of external libraries. The usual + procedure of cross compiling ACE/TAO applies + (such as setting HOST_ROOT environment variable). + +. Added support for Embarcadero C++ Builder 2010 + +. Added option to print a given ACE_Time_Value in the log + message instead of system supplied timestamp as in %T + and %D. + The option is implemented as a variant of the %D/%T + options by using the '#' flag character like '%#D' or + '%#T'. When using this flag an ACE_Time_Value pointer is + expected in the argument list supplied with the log message. + This fixed Bugzilla #3221. + +. Fixed problems with ACE_INET_Addr::is_multicast() on + little endian platforms. This fixed bugzilla #3729. + +. Added compilation support for VxWorks 6.8, no runtime + testing has been performed + +USER VISIBLE CHANGES BETWEEN ACE-5.7.4 and ACE-5.7.5 +==================================================== + +. Added MacOSX Snow Leopard support + +. Added strsignal() wrapper + +. Improved LynxOS support + +. Updated Interix port + +. Fixed MinGW compilation problems + +USER VISIBLE CHANGES BETWEEN ACE-5.7.3 and ACE-5.7.4 +==================================================== + +. ACE_CDR::consolidate now returns an int, 0 is ok, -1 is failure + +. Fixed a bug in the realclean feature of the GNU makefiles + +. Improved Sun Studio for Linux support + +. Improved OpenBSD support + +USER VISIBLE CHANGES BETWEEN ACE-5.7.2 and ACE-5.7.3 +==================================================== + +. C++ Builder 2009 Update 3 is the only C++Builder that is supported, older + and newer compilers are not supported anymore + +. Made final changes for the CEGCC port + +. Added a set of tests to validate C++ compiler and the stl implementation + they ship. + +. HP-UX PARISC aCC < 3.80 are deprecated and can't be used anymore. Upgrade + to aCC 3.80 or newer + +USER VISIBLE CHANGES BETWEEN ACE-5.7.1 and ACE-5.7.2 +==================================================== + +. Borland C++ makefiles aren't shipped anymore as part of the release + but have to be generated by the user + +. Refactored gperf to have its own shared library so that we can reuse + that in TAO + +. Added support for SuSE Enterprise 10 + +. ACE_Configuration_Heap::open() now returns -1 with errno EBUSY if it is + called multiple times. Previous versions would allow multiple calls to + open() but leak resources. + +USER VISIBLE CHANGES BETWEEN ACE-5.7.0 and ACE-5.7.1 +==================================================== + +. 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 <algorithm> + 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<TQ> 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 <cleeland_c@ociweb.com>" 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<CHAR>: + + 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 <kfh at mqsoftware dot com> 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<ACE_Thread_Mutex, long> and + ACE_Atomic_Op<ACE_Thread_Mutex, unsigned long> 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 ACE_MESSAGE_TYPE, ACE_SYNCH_DECL> class + is new, contributed by Guy Peleg <guy dot peleg at amdocs dot com>. + ACE_Message_Queue_Ex_N<class ACE_MESSAGE_TYPE, ACE_SYNCH_DECL> 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<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. |
