From Johnny Willemsen@21:1/5 to All on Mon May 2 03:25:04 2016
Once again, thanks to the efforts of many developers, testers, and
users, we are pleased to announce the micro release
of ACE 6.3.4 and TAO 2.3.4 which is available from the usual
download location at:
The doxygen documentation for this release is also available. In
addition to the packages combined of sources and generate makefiles,
this release provides source-only packages for developers who use MPC to generate their own makefiles.
We encourage you to download the new release, use it with your
applications, and let us know if you encounter any problems. Please use the:

The following is a list of key changes since the last major release.
Please refer to the corresponding ChangeLog files, NEWS files, or
Bugzilla entries for more details on the problem and the nature of fixes applied.
Changes to ACE
. ACE_SSL_Context::set_mode() can no longer be used to select a specific
SSL/TLS protocol version, use ACE_SSL_Context::filter_versions() for
that. This follows general advice by the OpenSSL project to go through
SSL_CTX_set_options() to limit the list of protocols available. The
purpose of ACE_SSL_Context::set_mode() is now limited to explicitly
restricting behaviour to client or server (defaults to both).
. Improve Oracle Studio support
. CIAO and DAnCE are forked to their own github repositories
and are not part anymore of the ACE+TAO release packages
. Fixed several Coverity reported issues
. Added ACE configuration for FACE safety profiles (see config-
face-safety.h). FACE, or Future Airborne Capability Environment http://www.opengroup.org/face, specifies a restricted subset of OS
functions and rules for controlling dynamic memory allocation. When
built in this configuration on a platform that supports it, ACE
conforms to the FACE requirements.
. ACE uses new netdb.h functions (getaddrinfo/getnameinfo) if they are
available, in place of deprecated functions (gethostbyname/addr).
Changes to TAO
. ImR enhancement - Added a "force remove" option to the Implementation
repository that will remove a server entry from the ImR Locator
repository and kill any running instance with a single command.
. ImR enhancement - Fix to allow very large ( > 4K ) command line.
. ImR enhancement - Enhance the coordination between the Locator and
the Activator to tolerate running on heavily loaded systems, in
particular when a server process is slow to shut down, and a new
server is started before the shutdown is complete
. LogWalker utility improvements for handling truncated GIOP buffer
dumps, added tracking thread first/last contact times.
. Fault-Tolerance improvement - Optimize performance on NFS mounted
filesystems. First a deadlock is resolved. Second, use of writer
locks is minimized to only when writing is necessary. Third, NFS
occasionally causes transient EBADF errors on access, so
file access that results in a bad file error is retried before the
error is reported to the application.
