| [heading Version 2.1.0 - Changes since boost 1.40] |
| |
| The 1.41.0 release of Boost adds futures to the thread library. There are also a few minor changes. |
| |
| [heading Changes since boost 1.35] |
| |
| The 1.36.0 release of Boost includes a few new features in the thread library: |
| |
| * New generic __lock_multiple_ref__ and __try_lock_multiple_ref__ functions for locking multiple mutexes at once. |
| |
| * Rvalue reference support for move semantics where the compilers supports it. |
| |
| * A few bugs fixed and missing functions added (including the serious win32 condition variable bug). |
| |
| * `scoped_try_lock` types are now backwards-compatible with Boost 1.34.0 and previous releases. |
| |
| * Support for passing function arguments to the thread function by supplying additional arguments to the __thread__ constructor. |
| |
| * Backwards-compatibility overloads added for `timed_lock` and `timed_wait` functions to allow use of `xtime` for timeouts. |
| |
| [heading Version 2.0.0 - Changes since boost 1.34] |
| |
| Almost every line of code in __boost_thread__ has been changed since the 1.34 release of boost. However, most of the interface |
| changes have been extensions, so the new code is largely backwards-compatible with the old code. The new features and breaking |
| changes are described below. |
| |
| [heading New Features] |
| |
| * Instances of __thread__ and of the various lock types are now movable. |
| |
| * Threads can be interrupted at __interruption_points__. |
| |
| * Condition variables can now be used with any type that implements the __lockable_concept__, through the use of |
| `boost::condition_variable_any` (`boost::condition` is a `typedef` to `boost::condition_variable_any`, provided for backwards |
| compatibility). `boost::condition_variable` is provided as an optimization, and will only work with |
| `boost::unique_lock<boost::mutex>` (`boost::mutex::scoped_lock`). |
| |
| * Thread IDs are separated from __thread__, so a thread can obtain it's own ID (using `boost::this_thread::get_id()`), and IDs can |
| be used as keys in associative containers, as they have the full set of comparison operators. |
| |
| * Timeouts are now implemented using the Boost DateTime library, through a typedef `boost::system_time` for absolute timeouts, and |
| with support for relative timeouts in many cases. `boost::xtime` is supported for backwards compatibility only. |
| |
| * Locks are implemented as publicly accessible templates `boost::lock_guard`, `boost::unique_lock`, `boost::shared_lock`, and |
| `boost::upgrade_lock`, which are templated on the type of the mutex. The __lockable_concept__ has been extended to include publicly |
| available __lock_ref__ and __unlock_ref__ member functions, which are used by the lock types. |
| |
| [heading Breaking Changes] |
| |
| The list below should cover all changes to the public interface which break backwards compatibility. |
| |
| * __try_mutex__ has been removed, and the functionality subsumed into __mutex__. __try_mutex__ is left as a `typedef`, |
| but is no longer a separate class. |
| |
| * __recursive_try_mutex__ has been removed, and the functionality subsumed into |
| __recursive_mutex__. __recursive_try_mutex__ is left as a `typedef`, but is no longer a separate class. |
| |
| * `boost::detail::thread::lock_ops` has been removed. Code that relies on the `lock_ops` implementation detail will no longer work, |
| as this has been removed, as it is no longer necessary now that mutex types now have public __lock_ref__ and __unlock_ref__ member |
| functions. |
| |
| * `scoped_lock` constructors with a second parameter of type `bool` are no longer provided. With previous boost releases, |
| ``boost::mutex::scoped_lock some_lock(some_mutex,false);`` could be used to create a lock object that was associated with a mutex, |
| but did not lock it on construction. This facility has now been replaced with the constructor that takes a |
| `boost::defer_lock_type` as the second parameter: ``boost::mutex::scoped_lock some_lock(some_mutex,boost::defer_lock);`` |
| |
| * The `locked()` member function of the `scoped_lock` types has been renamed to __owns_lock_ref__. |
| |
| * You can no longer obtain a __thread__ instance representing the current thread: a default-constructed __thread__ object is not |
| associated with any thread. The only use for such a thread object was to support the comparison operators: this functionality has |
| been moved to __thread_id__. |
| |
| * The broken `boost::read_write_mutex` has been replaced with __shared_mutex__. |
| |
| * __mutex__ is now never recursive. For Boost releases prior to 1.35 __mutex__ was recursive on Windows and not on POSIX platforms. |
| |
| * When using a __recursive_mutex__ with a call to [cond_any_wait_link `boost::condition_variable_any::wait()`], the mutex is only |
| unlocked one level, and not completely. This prior behaviour was not guaranteed and did not feature in the tests. |
