Migrates logs that are stored in the bitten_log_messages table into
files.
Done.
Recreates the bitten_rule table with an integer id column rather than
a text one.

purpose anymore.

Duplicate builds found. You can remove the builds you don't want to
keep by using this one-line command:

$  python -c "from bitten.model import Build; from trac.env import Environment; Build.fetch(Environment('/var/trac/bitten'), <buildid>).delete()"

...where <buildid> is the id of the build to remove.

Upgrades cannot be performed until conflicts are resolved.
