New submission from Brendan Dolan-Gavitt <brenda...@gatech.edu>: The default constructor for Maildir is rfc822.Message. This means that when iterating over a Maildir mailbox instantiated with default settings, the Mailbox class will return self._factory(self.get_file(key)), leaking the file descriptor returned by get_file(). Thus, iterating over any reasonably sized maildir mailbox will cause file descriptors to be leaked, and if a non-refcounting GC is used (as in PyPy), it is very likely that the process will run out of file descriptors.
I see that the default has changed to None, for Py3k, but this still means that using a message factory unavoidably leaks file descriptors. Ideally, I'd like the Mailbox class to close the file descriptor passed into the factory; this would mean that file descriptors are never leaked during iteration. ---------- components: Library (Lib) messages: 132988 nosy: moyix priority: normal severity: normal status: open title: Maildir iterator leaks file descriptors by default type: behavior versions: Python 2.5, Python 2.6, Python 2.7 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue11767> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
