From bc244533ccd72a0ad075571e338a6af35cc162f5 Mon Sep 17 00:00:00 2001 From: Rich Felker Date: Tue, 27 Sep 2011 18:22:31 -0400 Subject: [PATCH] improve/debloat mutex unlock error checking in pthread_cond_wait we're not required to check this except for error-checking mutexes, but it doesn't hurt. the new test is actually simpler/lighter, and it also eliminates the need to later check that pthread_mutex_unlock succeeds. --- src/thread/pthread_cond_timedwait.c | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) diff --git a/src/thread/pthread_cond_timedwait.c b/src/thread/pthread_cond_timedwait.c index faa7c23b..60ebbb97 100644 --- a/src/thread/pthread_cond_timedwait.c +++ b/src/thread/pthread_cond_timedwait.c @@ -37,8 +37,8 @@ int pthread_cond_timedwait(pthread_cond_t *c, pthread_mutex_t *m, const struct t struct cm cm = { .c=c, .m=m }; int r, e=0, seq; - if ((m->_m_type&3) == PTHREAD_MUTEX_ERRORCHECK && - (m->_m_lock&INT_MAX) != __pthread_self()->tid) return EPERM; + if (m->_m_type && (m->_m_lock&INT_MAX) != __pthread_self()->tid) + return EPERM; if (ts && ts->tv_nsec >= 1000000000UL) return EINVAL; @@ -58,7 +58,7 @@ int pthread_cond_timedwait(pthread_cond_t *c, pthread_mutex_t *m, const struct t seq = c->_c_seq; - if ((r=pthread_mutex_unlock(m))) return r; + pthread_mutex_unlock(m); do e = __timedwait(&c->_c_seq, seq, c->_c_clock, ts, cleanup, &cm, 0); while (c->_c_seq == seq && (!e || e==EINTR));
