When a Berkeley DB database is opened with DB_RECOVER, recovery against the database logs is run to recover transactions or data that were possibly lost when the database was not properly closed.
(for more details, see http://www.sleepycat.com/docs/ref/transapp/app.html)
Until now, we always opened the repository with DB_RECOVER since it is unharmful to run recovery when no recovery is needed and, in development mode, Chandler is constantly aborted instead of being properly quit.
The problem though is that running recovery takes some time, 2.5s on my Powerbook to be precise, whereas opening the repository without recovery only takes 0.03s. Given that we've got only 5s allotted from startup time, spending half of that on something we don't need is rather wasteful.
So, the repository open logic was changed to run recovery when it is actually needed and it now has ways to auto-detect that. If you want to force running recovery on your repository, you can use the Berkeley db_recover utility or start Chandler with -R (or --recover).
Startup time on my fast linux box went down by more thanb a second, and on my mac went down a full 2.5s. Little by little....
