Re: 'premature end of script headers' error

Bernhard,

Thank you for your response. I can find no traceback. None in the log file, nor the apache ssl_error_log which is where I have seen stack traces before. I peppered my systems tracker's roundup.cgi with more log messages - there is no python error at that level.  I made sure to catch any exception. I wrote a wrapper class (snarfed most of the code from http://code.activestate.com/recipes/577555-object-wrapper-class/) to have HTML text go to the log file as well as to sys.stdout. When I'm displaying the issue detail (issue.item.html) I see lots of HMTL in the log file. When I change a simple attribute and press the 'submit' button I see the SQL statements that I saw before, but no HTML text. This is why apache is complaining about the script headers - there aren't any. I'll have to dig deeper in the roundup/cgi/* code to determine where the error is. I'm thinking that something like this happens:

   create DB transaction
   do a lot of selects
   perform update and inserts
   some unknown error happens
   transaction is aborted

I'm pretty certain the database itself isn't the problem. I modified the same issue's attribute with roundup-admin and it works fine. I also did the UPDATE cut/pasted from the log using psql (the postgres command line) while logged as the user I'm using in the tracker. That also works fine.

If you think I'm going down the wrong path (digging into the roundup/cgi/* code) I'd appreciate your input.
