New submission from Kristján Valur Jónsson <krist...@ccpgames.com>:
in urllib2, you will find these lines:
# Wrap the HTTPResponse object in socket's file object adapter
# for Windows. That adapter calls recv(), so delegate recv()
# to read(). This weird wrapping allows the returned object to
# have readline() and readlines() methods.
# XXX It might be better to extract the read buffering code
# out of socket._fileobject() and into a base class.
r.recv = r.read
fp = socket._fileobject(r, close=True)
This, storing a bound method in the instance, will cause a reference
cycle that the user knows nothing about.
I propose creating a wrapper instance with a recv() method instead. Or,
is there a standard way of storing bound methods on instances? A
'weakmethod', perhaps?
