Yes, onerror allows you to delete an undeletable item. But, in the case of a mount point, the contents of the mounted filesystem get deleted *before* the mount point triggers onerror. This is the case described in issue #36422. The behavior provided by onitem allows you to provide a callback that can check for specific paths that may require special handling. This is especially useful if the onitem callback is also added to tempfile.TemporaryDirectory(). My PR handles a missing onitem argument the same way onerror is handled by providing a do-nothing stub function: if onitem is None: def onitem(*args): pass I don't know enough about CPython internals to tell the performance differences between such a stub function and wrapping each call to onitem in an "if" block. ---------- versions: +Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue37366> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
