* Re-fixed the EINTR bug that exists in some pthreads implementations.
It was originally fixed in https://svn.boost.org/trac10/ticket/6200 and
was accidentally disabled in 5b209c2e83.
* Made sure that the fix for the EINTR bug was consistently applied to
all code in the library.
* Made sure that all pthread_mutex_*() and pthread_cond_*() function
calls in the library were consistently decorated with
BOOST_THREAD_DISABLE_THREAD_SAFETY_ANALYSIS.
* If thread A was waiting to pull the earliest element off of a
sync_timed_queue, and while it was waiting thread B added a new element with an
earlier time to the queue, thread A wouldn't reduce how long it waited before
pulling the earliest element off of the queue.
* Also refactored a function name and a variable name since their names no
longer accurately described what they do:
*** notify_not_empty_if_needed() -> notify_elem_added()
*** not_empty_ -> cond_
* Also deleted a no-longer-used function:
*** wait_until_closed_until()
- Added missing includes.
- Added missing namespace qualification for Boost.Chrono casts.
- Added typedefs renaming polymorphic lockable wrappers to a more consistent
naming scheme. This fixes incorrect name references.
- Fixed incorrect duration casts in polymorphic lockable wrappers.
- Renamed upgrade_lockable_adapter to poly_upgrade_lockable_adapter, since
upgrade_lockable_adapter already exists and has a different meaning.
- Use BOOST_THREAD_FUTURE instead of future in executors and task region.
- Disable serial_executor_cont when executors or future continuations
are not enabled.
- Marked sync_queue_is_closed exception as visible.
The new set of tests iterates over Boost.Thread public headers and verifies that
each header is self-contained, i.e. doesn't have any missing includes and
contains syntactically correct content. On Windows and Cygwin, a second test
per each header is generated, which includes the header after windows.h. This
verifies that the header doesn't have conflicts with Windows SDK and that
includeing windows.h does not break platform detection in Boost.Thread.
This set of tests would have detected the bug fixed by
https://github.com/boostorg/thread/pull/263.
