Description

As raised in thread:

http://www.modpython.org/pipermail/mod_python/2007-June/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: Objects/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 content length and what request_rec says in respect of remaining amount of data as described in MODPYTHON-212.

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