New submission from Kevin Watters <kevinwatters at gmail.com>:
I cannot reproduce this locally yet, but I have several bug reports from users showing
that IMAP4_SSL connections can get stuck in an infinite loop during logout()
File "imaplib.pyo", line 529, in logout
File "imaplib.pyo", line 1059, in _simple_command
File "imaplib.pyo", line 889, in _command_complete
File "imaplib.pyo", line 990, in _get_tagged_response
File "imaplib.pyo", line 907, in _get_response
File "imaplib.pyo", line 1000, in _get_line
File "imaplib.pyo", line 1170, in readline
File "ssl.pyo", line 136, in read
IMAP4_SSL uses ssl.wrap_socket and should probably be passing
suppress_ragged_eofs=False. Without this, self.sslobj.read() may return '' forever, and
both IMAP4_SSL.read() and IMAP4_SSL.readline() will spin. With
suppress_ragged_eofs=False, calling logout() may raise an SSLError instead.
Thoughts?
