ACE 6.3.4 and TAO 2.3.4 released
The open source community has released ACE 6.3.4 and TAO 2.3.4
The open source community has released on Monday May 2nd 2016 a new ACE 6.3.4 and TAO 2.3.4 release. This release is available from the usual download location at http://download.dre.vanderbilt.edu/ under the heading “Latest Micro Release Kit”.
Or from the github release page at https://github.com/DOCGroup/ACE_TAO/releases/tag/ACE%2BTAO-6_3_4
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.
Changes to ACE (detailed changes)¶
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 (detailed changes)¶
- 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.
