[Jython-users] urllib.urlretrieve(): runtime exception

[Ben H. <be...@in...>]

Im getting an AttributeError in the httplib.py standard library when
using urlretrieve():

Traceback (innermost last):
  File "FutureSourceSpider.py", line 86, in ?
  File "c:\software\jython\Lib\urllib.py", line 68, in urlretrieve
  File "c:\software\jython\Lib\urllib.py", line 198, in retrieve
  File "c:\software\jython\Lib\urllib.py", line 169, in open
  File "c:\software\jython\Lib\urllib.py", line 273, in open_http
  File "c:\software\jython\Lib\httplib.py", line 430, in putrequest
AttributeError: __getitem__

The line throwing the error in inside an exception handler:
        try:
            self.send(str)
        except socket.error, v:
            # trap 'Broken pipe' if we're allowed to automatically
reconnect
>>>>   if v[0] != 32 or not self.auto_open: <<<<<
                raise
            # try one more time (the socket was closed; this will
reopen)
            self.send(str)

I instrumented this code and determined that it executes when there is a
timeout setting up a socket connection. This timeout condition is for my
purpoises, transient and non-fatal.
The underlying message: java.net.NoRouteToHostException: Operation timed
out: no further information

Possibly because this section rarely executes, a bug has gone
undiscovered?

I dont fully understand what would cause the AttributeError on the line
above, can someone explain?
