Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
pull: add --remote-hidden option and pass it through peer creation This option will allow to pull changesets that are hidden on the remote. This is useful when looking into a changeset?s evolution history, resolving evolution instability or mirroring a repository. The option is best effort and will only affect the pull when it can. The option will be ignored when it cannot be honored. Support for each type of peer is yet to be implemented. They currently all warn about lack of support. The warning code will get removed as peers gain support for this option. The option is still experimental, so we will have freedom to update the UI or implementation before it graduates out of experimental. Based on a changeset by Pierre-Yves David, which added the option.
