New submission from Xiang Zhang: When debugging our project I find something interesting. In PyOS_Readline it releases the GIL and delegate its job to PyOS_ReadlineFunctionPointer, which could be call_readline or PyOS_StdioReadline(I don't find where vms__StdioReadline is defined). But in the two functions, they use some C APIs like PyMem_Malloc/MALLOC, PyErr_SetString which need guarded by GIL. I don't understand why not doing find-grained lock control in call_readline or PyOS_StdioReadline since the code is ancient. :-(
I find this because our project makes test_cmd_line fail with `echo "Timer\n" | python -i -m timeit -n 1`. ---------- components: Interpreter Core messages: 300862 nosy: xiang.zhang priority: normal severity: normal status: open title: C APIs called without GIL in PyOS_Readline type: behavior versions: Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue31282> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
