Added by Johnny Willemsen almost 2 years ago

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 under the heading “Latest Micro Release Kit”.

Or from the github release page 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.

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, 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.

TAOX11: TAOX11 using Visual Studio 2015 RC runs successful!

Added by Johnny Willemsen almost 3 years ago

Our TAOX11 development team has tested all Community Technology Preview (CTP) versions of Microsoft Visual Studio 2015. Each CTP did reduce the number of issues but we never were able to get the core of TAOX11 to compile without errors.

With the recently released Release Candidate our team has now been able to compile the full TAOX11 code base and even more important all our TAOX11 unit tests do run without any failure! We can’t wait for the final release of Microsoft Visual Studio 2015 so that we can ship TAOX11 for Visual Studio!
