Hum, I found multiple projects using PyEval_AcquireLock() and PyEval_ReleaseLock(). Many of them look abandonned. But a few were modified earlier than 1 year old. -- ntripcaster2: Latest commit on Jun 2019 https://github.com/rinex20/ntripcaster2/blob/ef45763c4c0b063e46ef3bbfc9d63bafcd76e421/src/interpreter.c Example: PyEval_AcquireLock (); maininterpreterstate = mainthreadstate->interp; newthreadstate = PyThreadState_New (maininterpreterstate); PyEval_ReleaseLock (); -- I found usage of PyEval_AcquireLock() in an old version of pygame (1.9.1, latest is 1.9.6): PyEval_AcquireLock (); oldstate = PyThreadState_Swap (helper->thread); ... result = PyObject_CallFunction (helper->tell, NULL); ... PyThreadState_Swap (oldstate); PyEval_ReleaseLock (); https://github.com/z-pan/pygame_tankScout/blob/7977cc6756e948c37cb4aa56fb1009a74288b65c/pygame-1.9.1release/src/rwobject.c pygame changed to "PyGILState_Ensure() ... PyGILState_Release()" instead. -- giljoy (Latest commit in 2013): it seems to override symloads using LD_PRELOAD to measure time when the GIL is acquired and released. https://github.com/itamarst/giljoy/blob/master/giljoy.c -- xmlbus: Latest commit in 2014. https://github.com/olger/xmlbus/blob/148692997a481d10827a1aa86dc0ed3d70d84209/server/xmlbusd/pyrunner/pyrunner.c Example: PyEval_AcquireLock(); mainInterpreterState = mainThreadState->interp; PyThreadState_Swap(mainThreadState); myThreadState = PyThreadState_New(mainInterpreterState); PyEval_ReleaseLock(); ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39998> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
