New submission from Serhiy Storchaka <storchaka+cpyt...@gmail.com>:
There is a memory leak in comparison of sqlite.Row objects when row descriptors are different. There were not tests for this case. Also, the code compares the result of PyObject_RichCompare() with Py_True and Py_False. It is better to avoid such code, because technically PyObject_RichCompare() can return an arbitrary value, although in this particular case description can only be tuple or None (or NULL, but this is other issue). Also, there is a test for inequality of hash codes. Since hashes depend on hashes of strings, they value is random, and there is a small chance of failure. Hashes should not be tested for inequality. ---------- components: Library (Lib) messages: 352465 nosy: berker.peksag, ghaering, serhiy.storchaka priority: normal severity: normal status: open title: Memory leak in comparison of sqlite.Row objects type: resource usage versions: Python 2.7, Python 3.7, Python 3.8, Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue38175> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
