[New-bugs-announce] [issue13736] urllib.request.urlopen leaks exceptions from socket and httplib.client

[Jyotirmoy Bhattacharya]

New submission from Jyotirmoy Bhattacharya <jyotirmoy at jyotirmoy.net>:

The documentation for urlopen says that it raises URLError on error. 
But there exist error conditions such as a socket timeout or a bad HTTP status line under which the exception from the underlying library leaks through urllib, thus breaking the promise in the documentation.

I am attaching a test program that demonstrates this bug.
