We’re merging design.trac and unit-tests.trac into core.trac (but keeping separate SVN repos), taking advantage of Trac 0.12’s multi-repository support.
Everything is set up on Trac’s end, I just need two commands run:
trac-admin $ENV repository resync "tests" trac-admin $ENV repository resync "design"
… where $ENV would be the path to trac-environs/wp-core.
I then need two post-commit hooks, one on the unit-tests.svn repo, and the other on design.svn, both pointing to the wp-core environment:
trac-admin $ENV changeset added "design" $REV trac-admin $ENV changeset added "tests" $REV
