Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
clfilter: add a cache on repo for set of revision to filter for a given set. Recomputing the filtered revisions at every access to changelog is far too expensive. This changeset introduce a cache for this information. This cache is hold by the repository (unfiltered repository) and invalidated when necessary. This cache is not a protected attribute (leading _) because some logic that invalidate it is not held by the local repo itself.
