Graham Dumpleton commented on MODPYTHON-234:
--------------------------------------------

This error also seen by someone using Django and LimitRequestBody directive.

http://groups.google.com/group/djan...a18c0f8a294f5d1

This directive may perhaps be a way of reproducing the problem allowing it t
o be tracked down.

Do note though that as a separate issue, mod_python doesn't work properly wi
th LimitRequestBody. This is described in that discussion but I haven't logg
ed it as a separate issue yet.

ects/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, mos
t 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 d
ata 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 ra
ther than trusting content length.
