swap compiler error on clang 3.0 c++11. 783 784[heading Version 2.1.0 - Changes since boost 1.40] 785 786The 1.41.0 release of Boost adds futures to the thread library. There are also a few minor changes. 787 788[heading Changes since boost 1.35] 789 790The 1.36.0 release of Boost includes a few new features in the thread library: 791 792* New generic __lock_multiple_ref__ and __try_lock_multiple_ref__ functions for locking multiple mutexes at once. 793 794* Rvalue reference support for move semantics where the compilers supports it. 795 796* A few bugs fixed and missing functions added (including the serious win32 condition variable bug). 797 798* `scoped_try_lock` types are now backwards-compatible with Boost 1.34.0 and previous releases. 799 800* Support for passing function arguments to the thread function by supplying additional arguments to the __thread__ constructor. 801 802* Backwards-compatibility overloads added for `timed_lock` and `timed_wait` functions to allow use of `xtime` for timeouts. 803 804[heading Version 2.0.0 - Changes since boost 1.34] 805 806Almost every line of code in __boost_thread__ has been changed since the 1.34 release of boost. However, most of the interface 807changes have been extensions, so the new code is largely backwards-compatible with the old code. The new features and breaking 808changes are described below. 809 810[heading New Features] 811 812* Instances of __thread__ and of the various lock types are now movable. 813 814* Threads can be interrupted at __interruption_points__. 815 816* Condition variables can now be used with any type that implements the __lockable_concept__, through the use of 817`boost::condition_variable_any` (`boost::condition` is a `typedef` to `boost::condition_variable_any`, provided for backwards 818compatibility). `boost::condition_variable` is provided as an optimization, and will only work with 819`boost::unique_lock<boost::mutex>` (`boost::mutex::scoped_lock`). 820 821* Thread IDs are separated from __thread__, so a thread can obtain it's own ID (using `boost::this_thread::get_id()`), and IDs can 822be used as keys in associative containers, as they have the full set of comparison operators. 823 824* Timeouts are now implemented using the Boost DateTime library, through a typedef `boost::system_time` for absolute timeouts, and 825with support for relative timeouts in many cases. `boost::xtime` is supported for backwards compatibility only. 826 827* Locks are implemented as publicly accessible templates `boost::lock_guard`, `boost::unique_lock`, `boost::shared_lock`, and 828`boost::upgrade_lock`, which are templated on the type of the mutex. The __lockable_concept__ has been extended to include publicly 829available __lock_ref__ and __unlock_ref__ member functions, which are used by the lock types. 830 831[heading Breaking Changes] 832 833The list below should cover all changes to the public interface which break backwards compatibility. 834 835* __try_mutex__ has been removed, and the functionality subsumed into __mutex__. __try_mutex__ is left as a `typedef`, 836but is no longer a separate class. 837 838* __recursive_try_mutex__ has been removed, and the functionality subsumed into 839__recursive_mutex__. __recursive_try_mutex__ is left as a `typedef`, but is no longer a separate class. 840 841* `boost::detail::thread::lock_ops` has been removed. Code that relies on the `lock_ops` implementation detail will no longer work, 842as this has been removed, as it is no longer necessary now that mutex types now have public __lock_ref__ and __unlock_ref__ member 843functions. 844 845* `scoped_lock` constructors with a second parameter of type `bool` are no longer provided. With previous boost releases, 846``boost::mutex::scoped_lock some_lock(some_mutex,false);`` could be used to create a lock object that was associated with a mutex, 847but did not lock it on construction. This facility has now been replaced with the constructor that takes a 848`boost::defer_lock_type` as the second parameter: ``boost::mutex::scoped_lock some_lock(some_mutex,boost::defer_lock);`` 849 850* The `locked()` member function of the `scoped_lock` types has been renamed to __owns_lock_ref__. 851 852* You can no longer obtain a __thread__ instance representing the current thread: a default-constructed __thread__ object is not 853associated with any thread. The only use for such a thread object was to support the comparison operators: this functionality has 854been moved to __thread_id__. 855 856* The broken `boost::read_write_mutex` has been replaced with __shared_mutex__. 857 858* __mutex__ is now never recursive. For Boost releases prior to 1.35 __mutex__ was recursive on Windows and not on POSIX platforms. 859 860* When using a __recursive_mutex__ with a call to [cond_any_wait_link `boost::condition_variable_any::wait()`], the mutex is only 861 unlocked one level, and not completely. This prior behaviour was not guaranteed and did not feature in the tests. 862 863[endsect] 864 865[section:future Future] 866 867The following features will be included in next releases. 868 869# Add some minor features, in particular 870 * [@http://svn.boost.org/trac/boost/ticket/7589 #7589] Synchro: Add polymorphic lockables. 871 872# Add some features based on C++ proposals, in particular 873 * [@http://svn.boost.org/trac/boost/ticket/8273 #8273] Synchro: Add externally locked streams. 874 * [@http://svn.boost.org/trac/boost/ticket/8514 #8514] Async: Add a thread_pool executor with work stealing. 875 876# And some additional extensions related to futures as: 877 878 * [@http://svn.boost.org/trac/boost/ticket/8517 #8517] Async: Add a variadic shared_future::then. 879 880 881[endsect] 882 883
