New submission from Ruben Bakker <ruben.bakk...@gmail.com>:
When using imaplib.IMAP4_SSL to open a Gmail mailbox, the readline method can
go into a infinite loop. It happens after Gmail drops the connection, usually
after some time/inactivity. The next imaplib request will cause the infinite
loop inside the readline() method.
Steps to reproduce:
Perform this script (use python -i to get the prompt):
import imaplib
HOST="imap.gmail.com"
PORT=993
USERNAME="usern...@gmail.com"
PASSWORD="password"
server = imaplib.IMAP4_SSL(host=HOST, port=PORT)
server.login(USERNAME, PASSWORD)
def f():
print server.select("INBOX")
print server.uid("FETCH", "1:*", "(UID FLAGS BODY.PEEK[HEADER.FIELDS
(Subject)])")
Call the f() function and then wait about about an hour. Call f() again and
server.select() will not return but take all CPU.
Add this line in IMAP4_SSL
if not char: raise self.abort('socket error: EOF')
complete method:
def readline(self):
"""Read line from remote."""
line = []
while 1:
char = self.sslobj.read(1)
if not char: raise self.abort('socket error: EOF')
line.append(char)
if char == "\n": return ''.join(line)
