Refactor diffrevs/diffdir into changes -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Refactor diffrevs/diffdir into changes Add dirstate.changes to replace most of diffdir Add localrepository.changes to replace diffrevs/diffdir This code can now efficiently check for changes in single files, and often without consulting the manifest. This should eventually make 'hg diff Makefile' in a large project much faster. This also fixes a bug where 'hg diff -r tip' failed to account for files that had been added but not committed yet. manifest hash: 20fde5d4b4cee49a76bcfe50f2dacf58b1f2258b -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCxMxpywK+sNU5EO8RAhzOAJ9VLQJoC+hiRYQtTSPbDhXBEJfQZwCgpDx9 GAwQ9jZHNsgXckBfXNCkJV8= =hMuc -----END PGP SIGNATURE-----
