branches/zip: Fix bugs in the creation or dropping of the clustered index (PRIMARY KEY or UNIQUE INDEX on NOT NULL columns). innodb-index.test: Remove the --replace_regex directives. Replace correct values to the "Duplicate entry" messages. This will cause the test to fail until we somehow return the duplicate key values to MySQL. Add test cases for creating or dropping UNIQUE INDEX or PRIMARY KEY. innobase_copy_index_def(): Allow the function to copy a clustered index definition to a secondary one (UNIQUE INDEX). innobase_create_key_def(): Check the NOT NULL flag from the correct place. Copy the clustered index if it is a UNIQUE INDEX. ha_innobase::prepare_drop_index(): Refuse to drop the clustered index.

branches/zip: Fix bugs in the creation or dropping of the clustered index (PRIMARY KEY or UNIQUE INDEX on NOT NULL columns). innodb-index.test: Remove the --replace_regex directives. Replace correct values to the "Duplicate entry" messages. This will cause the test to fail until we somehow return the duplicate key values to MySQL. Add test cases for creating or dropping UNIQUE INDEX or PRIMARY KEY. innobase_copy_index_def(): Allow the function to copy a clustered index definition to a secondary one (UNIQUE INDEX). innobase_create_key_def(): Check the NOT NULL flag from the correct place. Copy the clustered index if it is a UNIQUE INDEX. ha_innobase::prepare_drop_index(): Refuse to drop the clustered index.

ERROR 23000: Duplicate entry 'ac' for key 'c'
branches/zip: Merge branches/fast-index-creation -r1413. Fix some bugs. The tests innodb and innodb-index fail, but that might be due to an old MySQL source tree being used.
