Raw Normal View History

MDEV-23842 Atomic RENAME TABLE - Major rewrite of ddl_log.cc and ddl_log.h - ddl_log.cc described in the beginning how the recovery works. - ddl_log.log has unique signature and is dynamic. It's easy to add more information to the header and other ddl blocks while still being able to execute old ddl entries. - IO_SIZE for ddl blocks is now dynamic. Can be changed without affecting recovery of old logs. - Code is more modular and is now usable outside of partition handling. - Renamed log file to dll_recovery.log and added option --log-ddl-recovery to allow one to specify the path & filename. - Added ddl_log_entry_phase[], number of phases for each DDL action, which allowed me to greatly simply set_global_from_ddl_log_entry() - Changed how strings are stored in log entries, which allows us to store much more information in a log entry. - ddl log is now always created at start and deleted on normal shutdown. This simplices things notable. - Added probes debug_crash_here() and debug_simulate_error() to simply crash testing and allow crash after a given number of times a probe is executed. See comments in debug_sync.cc and rename_table.test for how this can be used. - Reverting failed table and view renames is done trough the ddl log. This ensures that the ddl log is tested also outside of recovery. - Added helper function 'handler::needs_lower_case_filenames()' - Extend binary log with Q_XID events. ddl log handling is using this to check if a ddl log entry was logged to the binary log (if yes, it will be deleted from the log during ddl_log_close_binlogged_events() - If a DDL entry fails 3 time, disable it. This is to ensure that if we have a crash in ddl recovery code the server will not get stuck in a forever crash-restart-crash loop. mysqltest.cc changes: - --die will now replace $variables with their values - $error will contain the error of the last failed statement storage engine changes: - maria_rename() was changed to be more robust against crashes during rename.
