* lock tests: Fix build failure on GNU/Hurd (regression from 2017-01-05).Bruno Haible2017-02-212-2/+2
| | | | | | | | | Reported by Rene Saavedra <rennes@openmailbox.org> in https://debbugs.gnu.org/cgi/bugreport.cgi?bug=25821 via Paul Eggert. * lib/glthread/lock.h: On glibc systems without PTHREAD_RWLOCK_WRITER_NONRECURSIVE_INITIALIZER_NP, use the fallback implementation of rwlocks. * lib/glthread/lock.c: Likewise.
* lock: Fix link error (regression from 2017-01-05).Bruno Haible2017-02-011-0/+3
| | | | | | | * lib/glthread/lock.h [USE_POSIX_THREADS_WEAK]: Declare also pthread_rwlockattr_init, pthread_rwlockattr_setkind_np, pthread_rwlockattr_destroy weak. Reported by Tom G. Christensen <tgc@jupiterrise.com>.
* lock: Provide guarantee to avoid writer starvation for rwlocks.Bruno Haible2017-01-052-14/+225
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rationale is: 1) Read-preferring read-write locks are prone to writer starvation if the number of reader threads multiplied by the percentage of time they have the lock held is too high. 2) Write- preferring read-write locks are the only reliable way to avoid this. 3) There have been reports of 'test-lock' hanging on glibc systems http://lists.gnu.org/archive/html/bug-gnulib/2017-01/msg00009.html, and glibc indeed implements read-preferring rwlocks by default, see http://man7.org/linux/man-pages/man3/pthread_rwlockattr_setkind_np.3.html and https://sourceware.org/bugzilla/show_bug.cgi?id=13701 . * m4/pthread_rwlock_rdlock.m4: New file. * m4/lock.m4 (gl_LOCK): Invoke gl_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. * lib/glthread/lock.h [USE_POSIX_THREADS]: Test HAVE_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. Use a different implementation of rwlock initialization on glibc systems without HAVE_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. Use a different implementation of rwlocks altogether on non-glibc systems without HAVE_PTHREAD_RWLOCK_RDLOCK_PREFER_WRITER. [USE_PTH_THREADS]: Use a different implementation of rwlocks altogether. * lib/glthread/lock.c [USE_POSIX_THREADS] (glthread_rwlock_init_for_glibc): New function. [USE_POSIX_THREADS] (glthread_rwlock_rdlock_multithreaded): Update comment. [USE_PTH_THREADS]: New implementation of rwlocks. [USE_WINDOWS_THREADS] (glthread_rwlock_rdlock_func): Prefer writers over readers. * modules/lock (Files): Add m4/pthread_rwlock_rdlock.m4. (Depends-on): Add 'extensions'. * tests/test-rwlock1.c: New file. * lock-tests (Files): Add it. (Depends-on): Add usleep. (Makefile.am): Add test-rwlock1 to the tests.
* thread: Fix pth port.Bruno Haible2017-01-051-5/+6
| | | | | | | * lib/glthread/thread.h (pth_init): Declare weak. (glthread_create, glthread_sigmask, glthread_join, gl_thread_self, gl_thread_exit): Make sure Pth is initialized before invoking any Pth function.
