Now, in case signal destroyed() runs first: - mtx locked - flag set to true - empty cvar notified Thus, doesn't hang. In case we wait first: - mtx locked - flag is false - cvar notification arrives Of course semaphore code always runs serially since they're covered by a mutex. We have all our bases covered. Previously the code never hung simply because the "curthread" condition was always true. I removed the "curthread" code paths since they don't add anything. Also rvalue references got used incorrectly. compat: add asserts 2016-12-03T06:11:31Z Stanislaw Halik sthalik@misaki.pl 2016-12-03T06:11:31Z urn:sha1:0e8e2d5b103afa508f33c70904271e4fe72c870e compat/run-in-thread: fix on msvc 2017 2016-11-29T04:42:23Z Stanislaw Halik sthalik@misaki.pl 2016-11-29T04:40:30Z urn:sha1:1ab4751c9ac2d4e1dcc3b730f8dcf53500d728e5 compat/util: split out run-in-thread{,-async} 2016-10-26T05:25:50Z Stanislaw Halik sthalik@misaki.pl 2016-10-26T05:25:50Z urn:sha1:644494f7cf27cb8dbe89a50885f57a7266a06e63
