Unable to install new Tracs after Bitten install

Description

I have several Trac systems running and installed Bitten successfully. However I have recently tried to install another Trac and just receive a 500 server error when I try to browse to it.

Upon looking at the trac root webpage, it shows:

xxxx.db: Error (bad local file header in C:\Python23\lib\site-packages\bitten-0.6dev_r372-py2.3.egg)

Removing the egg from site-packages\ results in a message about the egg not being found. Note that I haven't tried adding Bitten into the components of the new Trac yet, it is just a default Trac install.

Additional: All existing Tracs are still functioning fine.

Can you look for a backtrace in the log?

comment:3 by russell.quinn@…, 18 years ago

This is the Apache error.log (I started up the Apache server, then browsed immediately to the non working Trac) :

He, are you sure you downloaded the egg… or simply saved the download HTML page?

comment:5 by russell.quinn@…, 18 years ago

yes, i built the Bitten egg myself and it was all working ok before.

But I don't think this problem is related to Bitten at all now. I restarted the webserver (to get a clean error.log for you above), but now every Trac I browse to results in the same server error. I've tried uninstalling and reinstalling Trac, but to no avail.

What could be happening? Are you saying that it shouldn't be expecting a HTML file at this point?

comment:6 by Christian Boos, 18 years ago

The error log shows that mod_python is trying to load as a python file a file which actually looks like an HTML file: from the log it could be the C:
Python23
lib
site-packages
mod_python
util.py file. Check what it contains.

Resolution:	→ invalid
Status:	new → closed

The problem was when I installed the updated util.py to enable file attachments to work in the Trac Wiki. Rolling back to the version installed with mod_python fixed all the problems described above.

Thanks for your help cboos.
