* locks: follow up to r1667900.Yann Ylavic2017-04-071-4/+2
| | | | | | | | | | | | | Axe the 'absolute' argument of apr_{thread,proc,global}_mutex_timedlock() which was confusing, hence 'timeout' is always relative now. It still makes sense (to me) to handle a negative timeout as INFINITE, a nul one as IMMEDIATE, and a positive one as an upper bound timeout (like most if not all of the underlying system calls...). git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1790488 13f79535-47bb-0310-9956-ffa450edef68
* apr_proc/global_mutex: Fix API regarding the native OS mutexesYann Ylavic2016-03-061-4/+12
| | | | | | | | | | | | | | | | | | | | | | | accessors from/to available APR mechanisms, adding the new functions apr_os_proc_mutex_get_ex() and apr_os_proc_mutex_set_ex() which give control to the user over the selected mechanisms, including the missing POSIX semaphores (sem_t) on platforms supporting them. For POSIX sems, this moves the "sem_t *psem_interproc;" member from struct apr_proc_mutex_t to apr_os_proc_mutex_t (now complete) so that we can avoid members duplication between the two structs, and hence replace all the doublons in apr_os_proc_mutex_t with an apr_os_proc_mutex_t member, called "os", to be used for runtime. This first commit aims to be backportable to 1.6.x, thus does not address the Netware case which requires an incompatible change of the apr_proc_mutex_t to a pointer type (the implementation is here since very similar to other changes is this commit, but it is commented out for now, a simple follow up is coming with the type change for trunk only...). git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1733775 13f79535-47bb-0310-9956-ffa450edef68

* locks: introduce apr_{thread,proc,global}_mutex_timedlock().Yann Ylavic2015-03-191-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | For proc mutexes, the new mechanism APR_LOCK_DEFAULT_TIMED usable at creation time allows for the best mechanism to be elected (unixes: 1 to 3, or specific: 4 to 7): 1. PROC_PTHREAD if pthread_mutex_timedlock() and pthread_mutex_set_robust_np() are both available, 2. SYSV if semtimedop() is availale, 3. POSIXSEM if sem_timedwait() is available, 4. BeOS' acquire_sem_etc() if available, 5. NetWare falls back to apr_thread_mutex_timedlock() as for others functions, 6. OS2's DosRequestMutexSem(), 7. Windows' WaitForSingleObject(). Otherwise (like when fcntl and flock only are availble, if that's ever possible), APR_ENOTIMPL is returned. For thread mutexes, the new flag APR_THREAD_MUTEX_TIMED, usable at create() time still, allows to switch to an implementation using a condition variable and apr_thread_cond_timedwait() when if no native mechanism is available (eg. NetWare, pthreads but without pthread_mutex_timedlock() available). On windows, this initializes a WaitForSingleObject()able handle (Mutex) instead of the fastest (but not timeout-able) CRITICAL_SECTION used by default. All apr_{thread,proc,global}_mutex_timedlock() functions can take a relative or absolute time, thanks to the last (boolean) argument. Test suite updated accordingly. git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@1667900 13f79535-47bb-0310-9956-ffa450edef68

| | | | | | | | | | | | | | | | | | | | named semaphores (sem_open). Because there are a few different implementations around, this uses the lowest common denominator in creating the semaphore name. As far as its location in DEFAULT priority, it's placed between pthread and sysvsem. Tested on Darwin (in which it's the new default) and Solaris. As part of the discovery of sem_open under Solaris, APR is now aware of shm_open (Posix shared memory) under Solaris as well, if someone wants to monkey with that :) PR: Obtained from: Submitted by: Reviewed by: git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@63222 13f79535-47bb-0310-9956-ffa450edef68

This is analog to the APR_LOCKALL method of apr_lock_t, and provides cross-process AND cross-thread mutual exclusion. I have provided a simple test (based on testprocmutex.c) and stubs for non-Unix platforms. git-svn-id: https://svn.apache.org/repos/asf/apr/apr/trunk@63001 13f79535-47bb-0310-9956-ffa450edef68
