-current: >From my understand of POSIX, sem_wait(3) should always be a cancellation point. However, when the semaphore's count is positive and the caller successfully decrements the count, sem_wait(3) does not call _pthread_testcancel(), so it's not a cancellation point.
See this totally contrived test case: http://www.vangyzen.net/FreeBSD/patches/sem_wait_cancel.c This patch seems like an appropriate fix: http://www.vangyzen.net/FreeBSD/patches/sem_wait_cancel.diff It adds a call to _pthread_testcancel() in the same location as _libc_sem_timedwait_compat() in libc/gen/sem.c. Is this a real bug, or am I missing something?
