Projects that depend on it are incorrect and should be fixed.
That's definitely correct; no one here is arguing against it. However, there are projects out there depending on it -- it worked since around Python 2.5, and is readily available in `os.` tab completion. I think that documenting the removal would be good for our users. Furthermore, not all of its uses can be fixed. I've seen it printed in books. There are many answers/guides/tutorials around mentioning os.errno, for example: http://nullege.com/codes/search/os.errno.EACCES https://ubuntuforums.org/showthread.php?t=1459923 http://code.activestate.com/recipes/580759-show-os-error-codes-and-messages-... https://www.georgevreilly.com/blog/2016/03/24/RaisingIOErrorForFileNotFound.... ... and people tend based their code on such recipes, rather than checking what's documented. And, of course, projects run into this: https://github.com/intel/bmap-tools/issues/34 https://bugzilla.redhat.com/show_bug.cgi?id=1583196 https://github.com/python/typeshed/issues/1646 ---------- nosy: +petr.viktorin resolution: not a bug -> status: closed -> open _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue33666> _______________________________________
