I've noticed problems with the GC in two applications. In one case the
application did not respond to SOAP-requests for 9 seconds, every couple of
minutes, when it really shouldn't have taken more than 20ms. In another case we
had one

The bug note contains a test script. You just have to generate a huge
JSON-blob, or allocate 1 GB or so and pickle it down to file and replace the
cjson.decode to pickle.loads, pickle is about 20 times faster without GC
Daniel Svensson dsvens...@gmail.com added the comment:
Or you could disable the GC only when decoding JSON data and reenable it
afterwards.
JSON was just an example, and disabling/enabling the GC is not safe in a
multithreaded environment

Working on getting a reasonable large file to test with on my laptop where I
have 2.6, 2.7, 3.2. The Python version where the problem became apparent was
2.5.2 as the software is deployed on Debian Lenny

using: (except in python2.5 case where simplejson is used, which ought to be
the same thing right?)
import time, gc, json, sys
def read_json_blob():
t0 = time.time()
fd = open(datatest1.json)
data = fd.read

Daniel Svensson dsvens...@gmail.com added the comment:
Yes, but this ticket was only opened due to time delta between no-gc and gc,
not as much absolute time, but that's a nice improvement.

A typical use case would be for a server to receive a connection, and
then send that connection over to another process that does the actual
work. This used to work with pyprocessing, and the support seems to be
available
Daniel Svensson dsvens...@gmail.com added the comment:
And to be clear, I have enabled connection pickling by issuing:
multiprocessing.allow_connection_pickling()

Amaury's patch to multiprocessing for issue 3125, removes the copy_reg

The documentation for inet_aton specifically says that it's used to
Convert an IPv4 address from dotted-quad string format. This however
is not really true, it does accept dotted-quad, but not dotted-quad
alone, but also these forms from
