New submission from Matěj Stuchlík: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "/usr/lib64/python2.7/imaplib.py", line 163, in __init__ self.open(host, port) File "/usr/lib64/python2.7/imaplib.py", line 229, in open self.sock = socket.create_connection((host, port)) File "/usr/lib64/python2.7/socket.py", line 553, in create_connection for res in getaddrinfo(host, port, 0, SOCK_STREAM): socket.gaierror: [Errno -2] Name or service not known
Steps to Reproduce: 1. run python interpreter 2. import imaplib 3. imaplib.IMAP4() Expected behavior would be, as per documentation, for imaplib to try to connect to localhost. The root cause is, I believe, this: socket.py::create_connection states "An host of '' [...] tells the OS to use the default." and thus imaplib uses '' as the default value for host, however from getaddrinfo (to which function the host variable is passed) documentation and source it seems to me that it expect None, not '' as the default value. Substituting '' for None as the default value for host in imaplib.py seems to resolve this issue, I've included a tentative patch that does just that. In case this will need patching I'd be more than happy to work on a more complete patch! :) ---------- components: Library (Lib) files: imaplib.patch keywords: patch messages: 193632 nosy: sYnfo priority: normal severity: normal status: open title: imaplib.IMAP4() ends with "Name or service not known" on Fedora 18 type: behavior versions: Python 2.7, Python 3.5 Added file: http://bugs.python.org/file31027/imaplib.patch _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue18540> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
