2020-07-17Fix MonitorMixin when the super's initialize has kwargsMasataka Pocke Kuwabara
Notes: Merged: https://github.com/ruby/ruby/pull/3310
2019-12-04new_cond before mon_initializeKoichi Sasada
MonitorMixin#new_cond can be called before mon_initialize, so we need to initialize `@monitor` before it. https://bugs.ruby-lang.org/issues/16255#note-4
2019-11-12Monitor#exit: check monitor ownership.Koichi Sasada
Monitor#exit should be called by only onwer Thread. However, there is not check for it.
2019-10-20make monitor.so for performance. (#2576)Koichi Sasada
Recent monitor.rb has performance problem because of interrupt handlers. 'Monitor#synchronize' is frequently used primitive so the performance of this method is important. This patch rewrite 'monitor.rb' with 'monitor.so' (C-extension) and make it faster. See [Feature #16255] for details. Monitor class objects are normal object which include MonitorMixin. This patch introduce a Monitor class which is implemented on C and MonitorMixin uses Monitor object as re-entrant (recursive) Mutex. This technique improve performance because we don't need to care atomicity and we don't need accesses to instance variables any more on Monitor class. Notes: Merged-By: ko1 <ko1@atdot.net>
