[issue9010] Infinite loop in imaplib.IMAP4_SSL when used with Gmail

I installed Python 2.7RC1 on Mac OS X 10.6.3 and tried my script and it
worked for me. Imaplib throws the right exception instead of looping
forever:

Traceback (most recent call last):
  File stdin, line 1, in module
  File imapmail/explore/test2.py, line 30, in f
server.select(INBOX)
  File

line 642, in select
typ, dat = self._simple_command(name, mailbox)
  File

 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.

 Tried to reproduce this on Python 2.7RC1. Seemed Ok to me. Took some 3
 seconds to call f() not only once, but twice, thrice.

[issue9010] Infinite loop in imaplib.IMAP4_SSL when used with Gmail

2010-06-16 Thread Ruben Bakker 

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)

I forgot to mention that the section after Add this line to IMAP4_SSL 
describes the solution. Sorry about that.
