Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Do not call the endOfLife method of the current state before advancing to a next state, because this would remove elements from cache that have been inserted just before - it would be impossible to make use of a cache in that case. gnv-artifacts/trunk@1144 c6561f87-3c4e-4783-a992-168aeb5c3f6f
