#13599: condition_variable::timed_wait never returns
------------------------------+------------------------------
 Reporter:  steven.cook@…     |      Owner:  Anthony Williams
     Type:  Bugs              |     Status:  new
Milestone:  To Be Determined  |  Component:  thread
  Version:  Boost 1.65.0      |   Severity:  Problem
 Keywords:                    |
------------------------------+------------------------------
 boost::condition_variable::timed_wait never returns if compiled with
 -DBOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC.

 this_thread::sleep and thread::timed_join exhibit the same problem, but
 both these functions are documented as deprecated. However
 condition_variable::timed_wait is not documented as deprecated.

 This can be worked around by using condition_variable::wait_for.

 The following simple test program demonstrates the problem in that it
 hangs forever. Removing the #define makes it return after one second.

 {{{
 #define BOOST_THREAD_HAS_CONDATTR_SET_CLOCK_MONOTONIC

 #include <boost/thread.hpp>
 #include <iostream>

 int main( int argc, char* argv[] )
 {
     boost::condition_variable cv;
     boost::mutex m;
     boost::mutex::scoped_lock lock( m );

     cv.timed_wait( lock, boost::posix_time::seconds( 1 ) );
     std::cout << "wait_for has returned" << std::endl;

     return 0;
 }
 }}}
