New submission from Erlend Egeberg Aasland <erlend.aasl...@innova.no>:
_PyArena_AddPyObject() only steals the object reference if successful. - In Parser/pegen.c, _PyPegen_fill_token(), the return value is not checked at all. - In Parser/asdl_c.py, none of the (two) calls to _PyArena_AddPyObject() decref on failure - Ditto for Python/Python-ast.c Attached patch fixes all callers. I'll put up a PR if it looks ok. Alternatively, one could make _PyArena_AddPyObject() _not_ steal the reference, but since it's an exposed API, that's probably not an option. ---------- files: patch.diff keywords: patch messages: 390559 nosy: erlendaasland, pablogsal priority: normal severity: normal status: open title: Fix possible _PyArena_AddPyObject ref leaks type: behavior versions: Python 3.10 Added file: https://bugs.python.org/file49943/patch.diff _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue43779> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
