All,
We are trying to nail down a memory leak that happens only when
documents are POSTed to the server.
For testing we have a short script that does:
while True:
dictionary_of_parameters = {'field1': 'a'*100000}
post('url...', dictionary_of_parameters)
Then we run "top" on the server and watch the server memory grow
without bound. Why do we know that the problem is in request.readline
()? If I go to mod_python.util.FieldStorage.read_to_boundary() and
add the following statement:
def read_to_boundary(...):
return True
...
as the first executable line in the function the memory does not grow.
I have read the req_readline a 1000 time and I can't figure out where
the problem is.
My config:
Python 2.4.1
mod_python 3.2.10
Our request handler does nothing other than using util.FieldStorage
(req) and req.write('hello').
I have some suspicion that it has to do with:
....
19 * requestobject.c
20 *
21 * $Id: requestobject.c 420297 2006-07-09 13:53:06Z nlehuen $
22 *
23 */
....
846 /* Free rbuff if we're done with it */
847 if (self->rbuff_pos >= self->rbuff_len && self->rbuff !=
NULL)
848 {
849 free(self->rbuff);
850 self->rbuff = NULL;
851 }
852
Though, I can't confirm.
