I've finally managed to replicate the bug consistently, so I've just submitted it to the Collector:

I now know what causes it so I'm able to work around it, which means that I'm afraid the offer of 400 quid to fix the bug is now withdrawn. Sorry.

The bug only occurs if the DTML Method that adds the large file tries to call a Z SQL Method that uses the ZPyGreSQLDA. Here's the description I just submitted to the Collector:

Yeah great, I'm bitten again. We had the same (upload) problem here and I didn't have time to think about it, but thanks to your debugging I know now for sure that I have quite a problem. Michel Pelletier and Chris McDonough explained it a bit in answers to this message: http://zope.nipltd.com/public/lists/zope-archive.nsf/ByKey/7C20E9F401FF8087 Chris even had a workaround: --- A solution is to add the following methods to the database adapter's DB class inside DB.py: def commit_sub(self, *arg, **kw): pass def abort_sub(self, *arg, **kw): pass --- The above is also used in the alpha version of DC's newest oracle adapter DCOracle2, As we use Loginmanager with postgres, I have know idea how to not invoke Z SQL methods when upload. Has anybody an idea if and under what circumstances the above snipped could do harm? cheers, oliver
