Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
clear the cache on commit for rdbms backends: Don't carry over cached values from one transaction to the next (there may be other changes from other transactions) see new ConcurrentDBTest for a read-modify-update cycle that fails with the old caching behavior.
