Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
sidedata: enable sidedata computers to optionally rewrite flags Sidedata computers may want to influence the flags of the revision they touch. For example, the computer for changelog-based copytracing can add a flag to signify that this revision might affect copytracing, inversely removing said flag if the information is no longer applicable. See inline documentation in `storageutil` for more details. Differential Revision: https://phab.mercurial-scm.org/D10344
