Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Add manifest hash to commit messages for easy signing -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Here's an example: This is the current manifest hash: e06d11165178d03c296ea7e7854f91e612a8d6bf It was copied from the HG: comment lines that are added to the commit. Then I wrote this commit message, signed it, then closed the commit. The manifest hash is a hash of all the files in the project together with the hashes of manifest's parents. Thus, signing the manifest hash allows us to verify the entire state of project at the time of the commit. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCmMrcywK+sNU5EO8RAoKwAJ4gPz2dI1Xh44N3tra43clUGhLVggCbBxuu 8pBZt85SA9ty39+e2+hL9WI= =t/xS -----END PGP SIGNATURE-----
