SystemError: bad argument to internal function
----------------------------------------------

Key: MODPYTHON-234
URL: https://issues.apache.org/jira/browse/MODPYTHON-234
Project: mod_python
Issue Type: Bug
Components: core
Affects Versions: 3.3.1, 3.2.10
Reporter: Graham Dumpleton


As raised in thread:

http://www.modpython.org/pipermail/...une/023795.html

when req.read() is called, on rare occasions it can generate the error:

05 18:33:49 2007] [error] [client 200.155.85.225] SystemError: Objec
ts/stringobject.c:3515: bad argument to internal function,

It is speculated that this is caused by an invalid value being supplied to _
PyString_Resize() with code associated with req.read(). In particular, most 
likely being supplied a negative value for size.

This issues possibly relates to problems with how mod_python makes use of co
ntent length and what request_rec says in respect of remaining amount of dat
a as described in MODPYTHON-212.

Further highlights how the code for req.read(), req.readline() and req.readl
ines() has to be completely revised and overhauled to simply read whatever i
s available rather than trusting content length.
