- Change some doc references from 'algorithm' to 'sched_algorithm'.
- Initial cut at supporting arbitrary user-coded scheduler properties.
- Set fiber_properties::sched_algo_ every time through awakened().
- Define sched_algorithm methods on fiber_base*, not worker_fiber*.
- Simplify detail::fifo by making tail_ point to last link pointer.
- Reimplement waiting_queue::push() using pointer-to-pointer trick.
- Reimplement waiting_queue::move_to() using fiber_base** scan.
- Make bounded_queue::tail_ a ptr* to simplify appending new nodes.
- Make unbounded_queue::tail_ a ptr* to simplify linking new nodes.
- Remove thread_affinity flag and access methods.
- Re-add thread_affinity specific to workstealing_round_robin.
- Remove 'priority' for every fiber, and its support methods.
scheduler and setting it with set_scheduling_algorithm(). Document
sched_algorithm interface class.
Fix the example in condition_variables.qbk to explicitly unlock 'lk'
before
calling process_data().
Earlier refactoring moved the unique_lock instantiation back to public
methods, though it was referenced in private methods. Pass it into those
methods.
Use std::size_t as argument type for barrier constructor.
Add bounded_queue::upper_bound(), lower_bound(), value_pop().
Make is_empty(), is_full() const.
Add TimePointType template param to push_wait_until(), pop_wait_until().
Introduce private push_(), try_push_(), push_wait_until_() helper methods:
each of push(), try_push() and push_wait_until() has two signatures for
value_type const& versus value_type&&, but the code paths are identical once
we have a new node_type in hand. Moreover, extract processing common to all
into private push_and_notify_() method. (This fixes an inconsistency in push()
exception behavior.)
Extract common processing from pop(), value_pop(), try_pop() and
pop_wait_until() to private value_pop_() method. This retains a node_type::ptr
to the old head node until return time, unifying the code paths between its
return-by-value and assign-through-reference callers. (This fixes an
inconsistency in try_pop() exception behavior.)
