http://bugs.python.org/issue16270 identified an issue with ftpwrapper.endtransfer that causes ftp fetches to hang in certain situations. A fix was applied to python 3. I see the same issue on python 2.7, and the patch from 16270 fixes it. Is there a reason this fix hasn't been backported to 2.7? To reproduce: import urllib url = "ftp://ftp.fu-berlin.de/pub/misc/movies/database/ratings.list.gz" fp = urllib.urlopen(url) fp.close() # hangs

Thanks for raising this issue, Chris Beaumont. Fixed in 2.7.x

This fix has caused to manifest itself in `urllib', too. AFAICS, it's impossible to fully fix `urllib' to correctly handle end-of-transmission response without fixing `ftplib' first.
