Re: [Python-Dev] Py_DECREF(m) on PyInit_xxx() failure?

30.11.17 17:42, Victor Stinner пише:

CPython has many C extensions with non-trivial PyInit_xxx() functions which has to handle failures. A few modules use "Py_DECREF(m); retutrn NULL;", but most functions only do "return NULL;". Is it a reference leak or not?

Example from Modules/posixmodule.c:

v = convertenviron(); Py_XINCREF(v); if (v == NULL || PyModule_AddObject(m, "environ", v) != 0) return NULL; Py_DECREF(v);

Does this code leak a reference on m? ... Oh, and maybe also leaks a reference on v?
