Public bug reported: release: 14.04.1 LTS version: 1.2.15-8ubuntu1.1 0
The function SDL_SemWaitTimeout returns an error result (-1) if the semaphore wait times out, when it should return SDL_MUTEX_TIMEDOUT per documentation. Ref: http://www.libsdl.org/release/SDL-1.2.15/docs/html/sdlsemwaittimeout.html The fix is to check for ETIMEDOUT value of errno: diff -ru libsdl1.2-1.2.15/src/thread/pthread/SDL_syssem.c libsdl1.2-fixed/src/thread/pthread/SDL_syssem.c --- libsdl1.2-1.2.15/src/thread/pthread/SDL_syssem.c 2012-01-19 01:30:06.000000000 -0500 +++ libsdl1.2-fixed/src/thread/pthread/SDL_syssem.c 2015-01-12 16:13:54.768791640 -0500 @@ -144,8 +144,12 @@ retval = sem_timedwait(&sem->sem, &ts_timeout); while (retval == -1 && errno == EINTR); - if (retval == -1) - SDL_SetError(strerror(errno)); + if (retval == -1) { + if (errno == ETIMEDOUT) + retval = SDL_MUTEX_TIMEDOUT; + else + SDL_SetError(strerror(errno)); + } #else end = SDL_GetTicks() + timeout; while ((retval = SDL_SemTryWait(sem)) == SDL_MUTEX_TIMEDOUT) { ** Affects: libsdl1.2 (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1409922 Title: libsdl 1.2 SDL_SemWaitTimeout incorrect behavior To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libsdl1.2/+bug/1409922/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
