Remove code never actually used in IGNORE; InnoDB just rolls back the latest row insert or update on a duplicate key error and leaves it for MySQL to decide whether to ignore the error
Make ANALYZE TABLE to update index cardinality and other statistics also for an InnoDB table; note that the estimates are based on 10 random dives, not on an exhaustive read of the table
Prevent crash if MySQL calls rnd_end WITOUT calling rnd_init first: only restore active_index if it the old value was pushed in rnd_init
Initialize active_index to a sensible value: prevent crash if we restore it to the original value after an table scan
Make InnoDB to restore old active_index value after a table scan: MySQL may assume that a scan does NOT change active_index; this partially fixes bug 241 of UPDATE ... ORDER BY ... but it still remains that MySQL actually ignores the ORDER BY for both MyISAM and InnoDB tables
log0recv.c:
Use fflush to make sure report of a corrupt log record is printed to .err log before mysqld crashes
Fix bug: MySQL could erroneously return Empty set if InnoDB estimated index range size to 0 records though the range was not empty; MySQL also failed to do the next-key locking in the case of an empty index range
Remove (already commented out) code about storing the latest relay log pos info to InnoDB: we will probably use only the master log pos info when we restart a slave after a crash
Prepare for 5.x where HA_READ_PREFIX_LAST may pass only a few first bytes of the last field in a key value
ha_innodb.cc:
In 4.0 always assume HA_READ_PREFIX_LAST passes a complete-field prefix of a key value; LIKE queries use a padding trick
Fix potential bug: if MySQL calls store_lock with the TL_IGNORE argument in the middle of query processing, then InnoDB select_lock_type could be reset to LOCK_NONE in a wrong place
Call pthread_mutex_destroy() on not used mutex.
Changed comments in .h and .c files from // -> /* */
Added detection of mutex on which one didn't call pthread_mutex_destroy()
Fixed bug in create_tmp_field() which causes a memory overrun in queries that uses "ORDER BY constant_expression"
Added optimisation for ORDER BY NULL
Temporary fix to make the new client/server protocol to work: fetch all columns in an index, even if not needed by the SELECT statement; Monty has to fix the parser to tell InnoDB what to fetch
