PLANNED MAJOR CHANGES "SOMETIME IN THE FUTURE" (i.e., exact beta not known)
===========================================================================
PLANNED MAJOR CHANGES TARGETED FOR ACE-5.5.3
====================================================
. (Remedy) VxWorks 6.3 support
USER VISIBLE CHANGES BETWEEN ACE-5.5.2 and ACE-5.5.3
====================================================
. 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.
. (OCI) 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 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).
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.
