| I've been spending some quality time with hexedit, vim and a little bit
of python. I can now generate a file which can be used in the unit test.
The problem seems to occur when a '\r' character is right at
readBlockSize boundary, which is 65368 in the current mod_python.util.
I have not yet tested Alexis's fix yet. It's possible that it doesn't
fix the problem but is just masking it since his code uses a
readBlockSize of 65536, which will not be a problem for ugh.pdf.
The attached script will generate a file that can be used for testing. I
haven't tried to integrate it into Nicolas's unit test as I wanted to
share my findings with everyone asap. I'll spend some more time on this
tommorrow.
Happy Bug Hunting,
Jim
