* Use proc mutex pthread by default when robust[_np]Yann Ylavic2019-03-221-6/+22
| | | | | | | | | | | | | On platforms that support pshared and robust pthread mutex, this is usually the best interprocess mutex mechanism because it's efficient, posix, not limited and not persistent on the system when the program exits (i.e. no need to delete it explicitely before leaving, like IPC SysV or files for instance). Note that on older POSIX systems pthread_mutex_{setrobust,consistent}() funcs existed with the non-posix _np() suffix, and we consider them equivalent. git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1856022 13f79535-47bb-0310-9956-ffa450edef68

| | | | | | | | | | | | | Axe the 'absolute' argument of apr_{thread,proc,global}_mutex_timedlock() which was confusing, hence 'timeout' is always relative now.

| | | | | | | | | | | | | | | | | | | When no native timedlock is available, fall back to a common/generic spin sleep proc_mutex_spinsleep_timedacquire() based on the configured APR_USE_*_SERIALIZE trylock. Otherwise, choose the best timedlock mechanism in the following order: 1. PTHREAD if HAVE_PTHREAD_MUTEX_ROBUST && (HAVE_PTHREAD_MUTEX_TIMEDLOCK || HAVE_PTHREAD_CONDATTR_SETPSHARED) 2. SYSV if HAVE_SEMTIMEDOP 3. POSIX if HAVE_SEM_TIMEDWAIT 4. The one of APR_USE_*_SERIALIZE, hence possibly non-robust and/or spinning with the same robustness as the underlying apr_proc_mutex_trylock() call. apr_proc_mutex_timedlock() won't return ENOTIMPL anymore. git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1790436 13f79535-47bb-0310-9956-ffa450edef68
