Fix corruption resulting from skipping parts of a revision group -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Fix corruption resulting from skipping parts of a revision group We were occassionally losing track of what revision a delta applied to when we skipped over deltas we already had and applying the delta against the wrong base. This could result in coredumps from mpatch, consistency errors, or failed verify. manifest hash: fcf20a8abfd81f08fae2398136b2ed66216b2083 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.0 (GNU/Linux) iD8DBQFCzu5SywK+sNU5EO8RAi10AJ9cqIfQzOzbcdH36t1LR/rY+UMtHwCeM79p Dtv+Jh0McLZr6nf4iJyhDgI= =5o6U -----END PGP SIGNATURE-----
