Revert the patch that put log debug code behind UNIV_LOG_DEBUG
log0log.ic, log0recv.c, log0log.c, log0log.h:
Revert 1.1730.18.1 about UNIV_LOG_DEBUG: debug code is often needed in debugging the production version
Do not assert in log0log.c, line 856 if ib_logfiles are too small for innodb_thread_concurrency. Instead, print instructions how to adjust my.cnf and call exit(1).
Merge with ibbackup; bug fix: .ibd files were extended 2 x the required amount; InnoDB does not create the small file inno_arch_log... any more at database creation
Multiple tablespaces for InnoDB
sql_table.cc:
Tell explicitly that InnoDB should retrieve all columns in CHECKSUM TABLE
sql_update.cc, sql_select.cc, my_base.h:
More descriptive flag name HA_EXTRA_RETRIEVE_ALL_COLS
Merge
trx0trx.c:
Print more info about a trx in SHOW INNODB status; try to find the bug reported by Plaxo
buf0buf.c:
Check that page log sequence numbers are not in the future
log0recv.c, log0log.c:
Fixed a bug: if you used big BLOBs, and your log files were relatively small, InnoDB could in a big BLOB operation temporarily write over the log produced AFTER the latest checkpoint. If InnoDB would crash at that moment, then the crash recovery would fail, because InnoDB would not be able to scan the log even up to the latest checkpoint. Starting from this version, InnoDB tries to ensure the latest checkpoint is young enough. If that is not possible, InnoDB prints a warning to the .err log
Remove potential starvation of a full log buffer flush: only flush up to the lsn which was the largest at the time when we requested the full log buffer flush
os0sync.h, os0sync.c:
Fix a bug in os_event on Unix: even though we signaled the event, some threads could continue waiting if the event became nonsignaled quickly again; this made group commit less efficient than it should be
Merge InnoDB-4.0.14: SAVEPOINT now implemented; InnoDB now accepts also column prefix keys; crashing bug in ON UPDATE CASCADE fixed; page checksum formula fixed
Fix bug: an index cursor can theoretically be restored in a wrong place
log0log.c:
Fix bug: if combined log file size is >= 2 GB in a 32-bit computer InnoDB can write log to a wrong position
Fix hang introduced by selective deadlock resolution
srv0srv.c, row0mysql.c:
Fix hang introduced by selective deadlock resolution + corruption caused by lock timeout or sel deadl res in ON DELETE CASCADE
