poplib - retr() getting stuck

[Roopesh]

Hi,

I am using poplib's retr() to fetch mails from my gmail account. It
works fine, in some cases it gets stuck inside the retr() method and
does not come out.

From the logs I could find that when retr() is called, it stops
executing further statements, nor does it throw an exceptions but
simply stops. My code is roughly like the foll:

try:
print "1"
mymsg = M.retr(msg_no)
print "2"
except poplib.error_proto, e:
print "exception1"
except Exception, e:
print "exception2"

What can be the reason for this? Can anyone help me.

Thanks
Roopesh

Probably the server stopped responding. By default, sockets have no
timeout value set - that is, a recv() call may block forever.
Try using socket.setdefaulttimeout
<http://docs.python.org/lib/module-socket.html> before creating the
connection, or search this group for past responses to this same problem.

Thanks for the help.

At present I have modified the poplib code as follows (In POP3 and
POP3_SSL classes): Is it the correct way?

def __init__(self, host, port = POP3_PORT):
self.host = host
self.port = port
msg = "getaddrinfo returns an empty list"
self.sock = None

socket.setdefaulttimeout(30)

for res in socket.getaddrinfo(self.host, self.port, 0,
socket.SOCK_STREAM):
af, socktype, proto, canonname, sa = res
try:
self.sock = socket.socket(af, socktype, proto)
self.sock.connect(sa)
except socket.error, msg:

Thanks
