branches/zip: Minor cleanup.
innobase_create_index_def(): Add parameter new_primary. innobase_copy_index_def(): Simplify the documented algorithm, and try to implement it properly. innodb-index.test: Replace CHECKSUM TABLE with something more stable and useful. The test passes on an older BitKeeper snapshot: ChangeSet@1.2475.18.9, 2007-05-08 11:16:41+02:00, jbruehe@mysql.com +1 -0 Raise version number after cloning 5.1.18-beta But it fails on a newer one where the statement alter table t1 add primary key (a), add key (b(20)); results in fast index creation: ChangeSet@1.2500.1.40, 2007-06-01 20:06:13+04:00, kostja@bodhi.(none) +2 -0 Merge bodhi.(none):/opt/local/work/mysql-5.0-runtime into bodhi.(none):/opt/local/work/mysql-5.1-runtime MERGE: 1.1810.2984.14
