Add bdiff.blocks / minor performance tweaks -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Add bdiff.blocks / minor performance tweaks This refactors bdiff.bdiff so that we can get a list of matching blocks of line numbers for use by annotate/unidiff. Minor performance tweaks: - - add a field for equivalence so we can keep h around a bit longer for cmp - - mix len into the hash to reduce collisions - - move an operation into the slow path in longest_match manifest hash: b1aee590b6291b31069ea8a86b6aa8fb259ac244 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCubu2ywK+sNU5EO8RAm4FAJ9r10aJpT7qA96nqGYFHcuy4XcIHgCfeFx5 q0PyTXeZQc7Fw5kwEPcoykI= =QXSb -----END PGP SIGNATURE-----
