log_checkpoint(), log_make_checkpoint_at(): Remove the parameter write_always. It seems that the primary purpose of this parameter was to ensure in the function recv_reset_logs() that both checkpoint header pages will be overwritten, when the function is called from the never-enabled function recv_recovery_from_archive_start(). create_log_files(): Merge recv_reset_logs() to its only caller. Debug instrumentation: Prefer to flush the redo log, instead of triggering a redo log checkpoint. page_header_set_field(): Disable a debug assertion that will always fail due to MDEV-19344, now that we no longer initiate a redo log checkpoint before an injected crash. In recv_reset_logs() there used to be two calls to log_make_checkpoint_at(). The apparent purpose of this was to ensure that both InnoDB redo log checkpoint header pages will be initialized or overwritten. The second call was removed (without any explanation) in MySQL 5.6.3: mysql/mysql-server@4ca37968da In MySQL 5.6.8 WL#6494, starting with mysql/mysql-server@00a0ba8ad9 the function recv_reset_logs() was not only invoked during InnoDB data file initialization, but also during a regular startup when the redo log is being resized. mysql/mysql-server@45e9167983 in MySQL 5.7.2 removed the UNIV_LOG_ARCHIVE code, but still did not remove the parameter write_always. |
