This also adds a check that MyISAM tables with incompatible checksums are detected by CHECK TABLE ... [FOR UPGRADE] and thus also by mysql_upgrade. The tables that are incomatible are MyISAM tables with ROW_FORMAT=fixed and has VARCHAR fields and have CHECKSUM enabled. Before these tables gave different checksum if you used CHECK TABLE with or without EXTENDED mysql-test/r/old-mode.result: Now we get same results with and without EXTENDED mysql-test/r/row-checksum-old.result: Initial results mysql-test/r/row-checksum.result: Initial results mysql-test/t/old-mode.test: Added test with QUICK to show that the live checksum is not used when running with --old mysql-test/t/row-checksum-old-master.opt: Start mysqld with --old mode to enable old checksum code mysql-test/t/row-checksum-old.test: Run row-checksum test under mysqld --old mysql-test/t/row-checksum.test: Verify that checksum are calculated the same way with and without EXTENDED We run this with several storage engines to ensure results are the same over storage engines sql/ha_partition.cc: Use new HA_HAS_xxx_CHECKSUM flags sql/handler.cc: Use new HA_HAS_xxx_CHECKSUM flags sql/handler.h: Split HA_HAS_CHECKSUM into HA_HAS_NEW_CHECKSUM and HA_HAS_OLD_CHECKSUM flags. This is a safe API change as only MyISAM and Maria should use these handler flags. sql/sql_show.cc: Use new HA_HAS_xxx_CHECKSUM flags sql/sql_table.cc: Use file->checksum() for live checksums if the life checksum method corresponds to the mysqld --old flag storage/maria/ha_maria.cc: Use new HA_HAS_xxx_CHECKSUM flags storage/myisam/ha_myisam.cc: Set HA_HAS_OLD_CHECKSUM and/or HA_HAS_NEW_CHECKSUM flags depending on if this is a new myisam or old myisam file Add method check_for_upgrade() to detect if the table is of old version with a checksum that is incompatible with CHECK TABLE ... EXTENDED storage/myisam/ha_myisam.h: Added check_for_upgrade() storage/myisam/mi_open.c: Removed not neede cast Initialize share->has_null_fields and share->has_varchar_fields variables storage/myisam/myisamdef.h: Added share->has_null_fields and share->has_varchar_fields
