`pthread_cancel()` error printed on key1 long press #186

Closed antonhornquist closed 6 years ago

i believe what should work wrt long press does work but, anyhow, to recreate this error getting printed:

start crone and matron (via ./build/matron/matron to check output).
load any script.
press and hold (long press) key1 once.
release key1.
press key1 again (short press will do): matron prints metro_stop(): pthread_cancel() failed; error specified thread does not exist to output.

i've seen this as well. looking at matron/src/metro.c shows the stop/cancel code is pretty robust (ie won't try to thread-cancel a stopped timer) so i'm not sure how this is slipping through. will keep looking.

tehn commented 6 years ago

this happens for all timers.
