[mod_python] [help]please give an input filter example ?

Interesting...

If you could change filterobject.c, around line 223, where the code looks
like:

       if (! APR_STATUS_IS_SUCCESS(self->rc)) {
            PyErr_SetObject(PyExc_IOError,
                            PyString_FromString("Input filter read error"));
            return NULL;
To:

       if (! APR_STATUS_IS_SUCCESS(self->rc)) {
            PyErr_Format(PyExc_IOError, "Input filter read error: %d",
                         self->rc);
            return NULL;

This will log the actual return code that Apache is returning on this
error, it might give us more information on what is really going on there.

Thanks,

Grisha
