Fix bug #8677: if one used LOCK TABLES, created an InnoDB temp table, and did a multi-table update where a MyISAM table was the update table and the temp table was a read table, then InnoDB aserted in row0sel.c because n_mysql_tables_in_use was 0. Also, we remove the assertion altogether and just print an error to the .err log if this important consistency check fails. Then it is up to the user to read the .err log and notice the problem if there still are errors in MySQL's table locking.
Fix InnoDB critical bug #7496; we scan the InnoDB data dictionary also at a normal mysqld startup, and create the spaces, so that we know the mapping space id -> .ibd file name; fix an infinite loop if DISCARD TABLESPACE coincides with INSERT or some other table operation; fix a potential crash if DISCARD TABLESPACE coincides with a cascaded FOREIGN KEY operation in the same table; do not allow DISCARD TABLESPACE of a referenced table if FOREIGN_KEY_CHECKS=1
Fix bug #6817 and bug #6827 : do not crash the server if the buffer pool becomes filled by the locks of ONE huge transaction, return error 1206 instead; do not crash the server, but return error if we cannot allocate memory for the buffer pool at a mysqld startup
X-locks on duplicates also on LOAD DATA...REPLACE clause and
fixes a bug #6086 adding --disable_warnings and --enable_warnings around
the create table clauses in ctype_utf8 tests for InnoDB.
next-key locking. Using this option the locks InnoDB sets on index
records do not affect the ``gap'' before that index record. Thus, this option
allows phantom problem.
Fix bug #2483 with InnoDB, UNIQUE secondary index, and NULL values in that unique index; with the IS NULL predicate, InnoDB returned only the first matching row, though there can be many
If MySQL tries to do SELECT from an InnoDB table, but has set no table locks at all in ::external_lock(), print a descriptive error message and assert; some subquery bugs were of this type
Fix assertion failure on line 713 of row0upd.c if there is a column prefix index and the last characters in the prefix are spaces: do not assume that the length of alphabetically equal strings is the same; fix a buglet which could cause InnoDB to think that a secondary index record was not locked though it had been updated in a way which did not alpahabetically change its value, e.g., abc -> aBc
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
If innodb_force_recovery >= 5, do not try to fetch an old version of a clustered index record: this reduces crashes when dumping tables from a corrupt database
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
Fix bug: if a primary key contains more than one column, then MySQL seems to do fetch next even for a unique search condition: this in turn caused unnecessary locking which did not agree what the InnoDB manual promised
Fix bug: InnoDB could print that it cannot find a clustered index record if an update undo, purge, and a consistent read coincided, in rare cases it might also have returned a wrong row in a query
