a9ca1710c000a62165d496a9444222e7ac02d70f - Add a complete C11 threads(3) implementation

Wed, 24 Apr 2019 11:43:19 +0000

Add a complete C11 threads(3) implementationC11 Thread support library is a portable threading C API between OSs,similar to std::threads in the C++ world.The library is implemented as a thin shim over POSIX interfaces.NetBSD implements the API as a part of the POSIX threading library(libpthread(3)).C11 threads(3) are in the process of making them an integral partof the POSIX standard. The interface has been implemented in majorOSs and used with stopgap libraries for older versions of them.C11 threading library is already used (with a stopgap implementation)in the NetBSD distribution in MESA.Original implementation by myself from 2016.ATF tests are new and cover almost all interfaces.Proposed on tech-userlevel@.

e5678be828932e6f3c8f31897ff2b79723f3129b - Implement __cxa_thread_atexit and __cxa_thread_atexit_impl. This

Tue, 11 Jul 2017 15:21:31 +0000

Implement __cxa_thread_atexit and __cxa_thread_atexit_impl. Thisfunctions are used for destructors of thread_local objects.If a pending destructor exists, prevent unloading of shared objects.Introduce __dl_cxa_refcount interface for this purpose. When the lastreference is gone and the object has been dlclose'd before, theunloading is finalized.Ideally, __cxa_thread_atexit_impl wouldn't exist, but libstdc++ insistson providing __cxa_thread_atexit as direct wrapper without furtherpatching.

53e134ea9efd113dd75cd0057fb0cb10c274758b - Add new test t_timedmutex

Sun, 30 Oct 2016 16:17:16 +0000

Add new test t_timedmutexThis test is a clone on t_mutex with additional two tests for timed-mutexspecific block.All simple-mutex (not with the timed property according to the C11 wording)specific tests are covered by pthread_mutex_timedlock(3) with parameterts_lengthy of sufficiently large tv_sec value (right now UINT16_MAX). If,a test will hang, it won't wait UINT16_MAX seconds, but will be terminatedwithin the default timeout for ATF tests (right now 300 [sec] in myNetBSD/amd64 setup).This test was inspired by a classic selflock test failure ofpthread_mutex_timedlock(3) of the following form:#include #include #include #include #include int main(int argc, char **argv){ pthread_mutex_t mtx; struct timespec ts; ts.tv_sec = 0; ts.tv_nsec = 1000; printf("ts{.tv_sec = %d, .tv_nsec=%ld}\n", ts.tv_sec, ts.tv_nsec); fflush(stdout); printf("mtx_init\n"); assert(pthread_mutex_init(&mtx, NULL) == 0); printf("mtx_lock\n"); assert(pthread_mutex_lock(&mtx) == 0); printf("mtx_timedlock\n"); assert(pthread_mutex_timedlock(&mtx, &ts) == ETIMEDOUT); printf("mtx_unlock\n"); assert(pthread_mutex_unlock(&mtx) == 0); printf("mtx_destroy\n"); assert(pthread_mutex_destroy(&mtx) == 0); return 0;}Current NetBSD implementation wrongly hangs on this test.The issue was detected during development of the C11 portable threads.My local tests in chroot presents that the are further issues:t_timedmutex (21/25): 10 test cases mutex1: [0.001142s] Failed: /usr/src/tests/lib/libpthread/t_timedmutex.c:75: *param != 20 mutex2: [0.261499s] Passed. mutex3: [0.261496s] Passed. mutex4: [0.001204s] Failed: /usr/src/tests/lib/libpthread/t_timedmutex.c:265: pthread_mutex_timedlock(&mutex, &ts_lengthy): Connection timed out mutex5: [0.001235s] Failed: /usr/src/tests/lib/libpthread/t_timedmutex.c:337: pthread_mutex_timedlock(&mutex5, &ts_lengthy): Connection timed out mutex6: [21.218497s] Failed: /usr/src/tests/lib/libpthread/t_timedmutex.c:512: start != 1 mutexattr1: [0.001328s] Passed. mutexattr2: [0.001175s] Passed. timedmutex1: [301.119397s] Failed: Test case timed out after 300 seconds timedmutex2: [301.123081s] Failed: Test case timed out after 300 seconds[623.990659s]I'm also receiveing the same failure in the mutex6 test in t_mutex, sothere might be a false positives due to local chroot(8) issues.Commit approved by .

bba80928a8e56a4c71f630c473d35391888cc3e9 - setcontext() used to be incompatible with -lpthread since it affected

Wed, 12 Sep 2012 02:00:51 +0000

setcontext() used to be incompatible with -lpthread since it affectedthe TLS pointer, therefore wrecking the pthread environement.Some ports had _UC_TLSBASE flag or equivalent (_UC_UNIQUE on alpha)that controlled whether setcontext() would change the TLS pointer.This change let libpthread override setcontext() with its own versionthat unsets _UC_TLSBASE, enabling safe usage of setcontext() with-lpthread.We also have the following required changes here:- rename alpha's _UC_UNIQUE into _UC_TLSBASE- add _UC_TLSBASE definition in header file for all ports (powerpc, sh3, sparc and sparc64 lack the implementation for now)- introduce a libc stub that can be overriden for setcontext()- modify MD libcs swapcontext() implementations so that they use the setcontext() libc stub instead of doing a plain system call.While we are there:- document various MD _UC_* flags in header file- add libc and libpthread tests for swapcontext() behavior (hopefully helpful to spot MD problems introduced with this change)Future work:- Deciding whether kernel support or _UC_TLSBASE should be added for powerpc, sh3, sparc and sparc64 is left to portmasters sparc64Approved by core@ List of files: /netbsd-src/tests/lib/libpthread/Makefile
