- Reserver namespace and place in frm for TABLE_CHECKSUM and PAGE_CHECKSUM create options - Added syncing of directory when creating .frm files - Portability fixes - Added missing cast that could cause bugs - Code cleanups - Made some bit functions inline - Moved things out of myisam.h to my_handler.h to make them more accessable - Renamed some myisam variables and defines to make them more globaly usable (as they are used outside of MyISAM) - Fixed bugs in error conditions - Use compiler time asserts instead of run time - Fixed indentation HA_EXTRA_PREPARE_FOR_DELETE -> HA_EXTRA_PREPARE_FOR_DROP as the old name was wrong (Added a define for old value to ensure we don't break any old code) Added HA_EXTRA_PREPARE_FOR_RENAME as a signal for rename (before we used a DROP signal which is wrong) - Initialize error messages early to get better errors when mysqld or an engine fails to start - Fix windows bug that query_performance_frequency was not initialized if registry code failed - thread_stack -> my_thread_stack_size
