Resolution: Fixed
> Memory leak in request readline()
> ---------------------------------
>
> Key: MODPYTHON-182
> URL: http://issues.apache.org/jira/browse/MODPYTHON-182
> Project: mod_python
> Issue Type: Bug
> Components: core
> Affects Versions: 3.2.10, 3.3, 3.2.x
> Environment: Apache 2.0.55 mpm-worker
> Reporter: Jim Gallacher
> Assigned To: Jim Gallacher
> Fix For: 3.3
>
>
> There is at least one memory leak request.readline(). I'm currently auditing
> the code so there may well be others.
> I think the leak will only occur when the request body is incompletely read
> with readline, which is likely an unusual corner case. The following
> demostrates the leak:
> Consider a request body consisting of:
> '\n'.join([ 'a'*100 for i in xrange(0, 100) ])
> and using this handler:
> def handler(req):
> # Handler reads 20 lines but request contains 100 lines.
> # Since the body is not completely read, the buffer allocated
> # in requestobject.c req_readline is never freed.
> req.content_type = 'text/plain'
> count = 0
> for i in range(0, 20):
> line = req.readline()
> count += 1
> req.write('ok readline_partial: %d lines read' % count)
> return apache.OK
> With this test setup I'm seeing a leak of approx 10k bytes per request.
