New submission from STINNER Victor <vstin...@python.org>:
In Modules/_hashopenssl.c:PyInit__hashlib(), PyModule_AddObject() can be replaced with PyModule_AddType() to add the 3 types: this function does the Py_INCREF for us, which reduces errors if the function fails. The results of other PyModule_AddObject() calls should also be checked to handle errors. The following _hashlibstate_global macro is no longer used: #define _hashlibstate_global ((_hashlibstate *)PyModule_GetState(PyState_FindModule(&_hashlibmodule))) EVPnew() got a module parameter, so it doesn't need _hashlibstate_global anymore. Dong-hee, Hai: Maybe it's time to convert this module to PEP 489 multiphase initialization? Hai: do you want to work on a PR? -- Question: do EVPobject and HMACobject rely on a global state somewhere in OpenSSL? Or is it safe to use them in subinterpreters, with multiple instances of _hashlib? EVPobject and HMACobject have "lock" member. Even if converting the module to PEP 489 is not enough to make it compatible with subinterpreters (I don't know, maybe it's enought, see my question), it should help for that :-) Note: the current code is already quite clean, I like it :-) cc Petr & Christian. ---------- components: Library (Lib) messages: 369211 nosy: christian.heimes, corona10, petr.viktorin, shihai1991, vstinner priority: normal severity: normal status: open title: Convert _hashlib to PEP 489 multiphase initialization type: enhancement versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue40671> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
