just::thread C++0x Thread Library V1.6 (FDIS Edition) Released

Wednesday, 25 May 2011

I am pleased to announce that version 1.6 (the FDIS edition) of just::thread, our C++0x Thread Library has just been released.

If you're interested in C++0x, I'm sure you're aware that the C++0x Final Draft International Standard (FDIS) was voted out at the last C++ Standards Committee meeting. See Michael Wong's blog post and Herb Sutter's blog post if you've been hiding under a rock for the last two months.

Anyway, after the vote at the meeting, the FDIS itself was published in April, and just::thread has now been updated to match the FDIS as close as possible. Where there have been changes to names (such as std::chrono::system_clock::to_time_point becoming std::chrono::system_clock::from_time_t) the old names have been kept, though they are marked "deprecated" using compiler annotations.

Changes include:

• Support for gcc 4.6 on Ubuntu Natty (using the packages from the Ubuntu Toolchain PPA) and Fedora 15.
• Support for thread-local variables with non-trivial constructors and destructors using the JSS_THREAD_LOCAL macro in place of the new thread_local keyword (which is not supported in any current compilers) .
• The std::hash<std::thread::id> specialization has been added.
• The new constexpr and noexcept keywords are used where supported (gcc 4.6 in -std=c++0x mode.)
• The return type of lambda functions is correctly deduced in std::async in both gcc 4.5 and 4.6 and MSVC 2010.
• Various optimizations, including reduction in thread creation code and the overhead of std::async.
• Added std::chrono::system_clock::from_time_t in place of std::chrono::system_clock::to_time_point.

As usual, existing customers are entitled to a free upgrade to V1.6.0 from all earlier versions.
