STINNER Victor added the comment: > Does the API doc say anything about the GIL, for example?
I modified Python to add assert(PyGILState_Check()); in PyMem_Malloc() and other functions. Sadly, I found a bug in Numpy: Numpy releases the GIL for performance but call PyMem_Malloc() with the GIL released. I proposed a fix: https://github.com/numpy/numpy/pull/7404 I guess that the fix is obvious and will be quickly merged, but it means that other libraries may have the issue. Using the issue #26516 (PYTHONMALLOC=debug), we can check PyGILState_Check() at runtime, but there is currently an issue related to sub-interpreters. The assertion fails in support.run_in_subinterp(), function used by test_threading and test_capi for example. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26249> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
