Alex is correct: mechanize.urlopen
takes a timeout
argument. Therefore, just insert a number of seconds in floating point: mechanize.urlopen('http://url/', timeout=30.0)
.
The background, from the source of mechanize.urlopen
:
def urlopen(url, data=None, timeout=_sockettimeout._GLOBAL_DEFAULT_TIMEOUT):
...
return _opener.open(url, data, timeout)
What is mechanize._sockettimeout._GLOBAL_DEFAULT_TIMEOUT
you ask? It's just the socket
module's setting.
import socket
try:
_GLOBAL_DEFAULT_TIMEOUT = socket._GLOBAL_DEFAULT_TIMEOUT
except AttributeError:
_GLOBAL_DEFAULT_TIMEOUT = object()

If you're using Python 2.6 or better, and a correspondingly updated version of mechanize
, mechanize.urlopen
should accept a timeout=...
optional argument which seems to be what you're looking for.

I believe something along the lines of
mechanize._sockettimeout._GLOBAL_DEFAULT_TIMEOUT = 100
will override the default value Mechanize uses.
