I just updated the trac from 0.11 to 0.12 because the multi repository browsing. Before the svn synchronization worked automatically, but now I have to the admin panel and type the repository resync *
command, is there any way to do this automatically?
You should read TracRepositoryAdmin and follow the instructions there. Basically, you have two options:
trac-admin $ENV changeset added
in the post-commit hook of each repository. This is the preferred option.
