ACE 7.0.0 and TAO 3.0.0 released

Changes to ACE (detailed changes)

  • C++11 is now a mandatory compiler feature which is required for ACE. Cleaned up part of the support for compilers that lack C++11 support
  • When valgrind is enabled we don’t disable dlclose anymore, this reduces the amount of leaks reported related to dlclose. When you unload your shared libraries before the end of your program you can use --keep-debuginfo=yes as valgrind options as alternative or you can disable dlclose yourself by adding #define ACE_LACKS_DLCLOSE to your ace/config.h file
  • Removed ACE_OS::readdir_r. readdir_r was marked as depracated in glibc and FreeBSD libc. Also removed ACE_Dirent::read (ACE_DIRENT *, ACE_DIRENT **) which used it. ACE_LACKS_READDIR_R will now always be defined.
  • Modernized part of the code using clang-type, added override, use nullptr, use unique_ptr, remove redundant void, use bool, simplify boolean expressions, make use of std::atomic, use using
  • New Latest_ACE7TAO3_ branches which can be used to always checkout the latest ACE7/TAO3 micro/minor release
  • Android Support:
    • `gnuace` no longer supports Android NDKs before r18. This means only clang is now supported when building for Android.
    • Support for building with the Android NDK r19 or later directly instead of having to use a generated standalone toolchain. See ACE-INSTALL.html for details. Using a standalone toolchain is still supported.
    • Made it easier to use `gnuace`-built libraries in as imported libraries in CMake-based Android Studio native projects.
    • Removed support for old ANDROID_ARCH make variable. Replaced ANDROID_ABI with android_abi, but kept the former as an alias of the later for compatibility. Also will no longer default to 32-bit ARM, so android_abi or ANDROID_ABI must be defined.
    • As recommend by Google, building with neon support is now the default when android_abi is armeabi-v7a. If support for these processors without NEON extensions is needed, put androind_neon := 0 in platform_macros.GNU.
    • As recommend by Google, `gnuace` will start using LLD, the LLVM linker, instead of the default GNU linkers. If the NDK being used doesn’t default to LLD and you want to use the GNU linkers, put androind_set_lld := 0 in platform_macros.GNU.
  • Removed support for the Alpha CPU

Changes to TAO (detailed changes)

  • C++11 is now a mandatory compiler feature which is required for TAO
  • Fixed some CORBA spec mismatches for the CORBA server portable interceptors
  • Add portspan support to DIOP

Time to modernize ACE/TAO!

Added by Johnny Willemsen almost 2 years ago

We are pleased to announce that ACE/TAO are getting modernized! The core developer group has supported very old (and broken) compilers for a long time, but it is now time to start modernizing ACE/TAO with the features and capabilities of C++11!

The coming period the core developer group will make C++11 a mandatory compiler feature for ACE 7.0.0 and TAO 3.0.0. This upcoming new major release is almost 10 years after ACE 6.0.0 and TAO 2.0.0 which where released December 14th 2010.

When you are using a C++11 capable compiler you should only notice that ACE/TAO will use C++11 features and that we will provide new C++11 APIs which will simplify your application code. There is no need to update your ACE 6.5.x based code, just recompile it with upcoming ACE 7.0.0 and TAO 3.0.0 and it should work. C++11 capable compilers are for example Visual Studio 2015 and newer, gcc 4.8 and newer, and clang 5 and newer.

When you are using a C++ compiler which doesn’t support C++11 you can keep using the ACE 6.5.x and TAO 2.5.x releases. When there is enough user sponsoring the core developer group will release new 6.5.x ACE/TAO releases with user funded bug fixes and enhancements! For this a new ace6tao2 branch is created in the ACE/TAO git repository which will be the development branch for any new 6.5.x developments.
