Major problem with out of synch Trac and SVN Repository.

[kphayward@…]

We have just had to restore a server from backup which held our Trac Python engine and SVN Repository on its C: drive. The physical SVN Folders and PostgreSQL database (Trac) are on a seperate E: drive.

The end result is that the SVN repo. only holds information up to the last backup/snapshot at Oct 17th 9:25 am, while the actual files on E: are the latest commits performed up until Oct 18th at approx. 4:00pm. So Trac appears to be pretty upset with not being able to see the latest SVN Changeset in the now out of date Repository. Hence we see the error message below, everytime we try to access our Trac project.

I know that this is mostly an SVN Repo. problem but I thought it worth while to let you see the Python Traceback and hope that someone may have had to deal with this sort of problem before.
