Cleaned up embedded library access and query cache handling
Changed min stack size to 128K (to allow longer MyISAM keys)
Fixed wrong priority for XOR (should be less than NEG to get -1^1 to work)
Fixed problem with char > 128 in QUOTE() function. (Bug #1868)
Disable creation of symlinks if my_disable_symlink is set
Fixed searching of TEXT with end space. (Bug #1651)
Fixed caching bug in multi-table-update where same table was used twice. (Bug #1711)
Fixed problem with UNIX_TIMESTAMP() for timestamps close to 0. (Bug #1998)
Fixed timestamp.test
Fixed compiler warnings (a lot of hidden variables detected by the Forte compiler)
Added a lot of 'version_xxx' strings to 'show variables'
Prevent copying of TMP_TABLE_PARAM (This caused core dump bug on Solaris)
Fixed problem with printing sub selects to debug log
Added option --max-record-length=# to myisamchk
Don't try repair twice if doing myisamchk --repair --force
Shared memory handler didn't clean up things on errors or shutdown
Fix the OS error 2 reported by Miguel and Mark in Windows crash recovery: a * had been forgotten from the path in directory scanning
ha_innodb.cc:
Set default directory in fil0fil.c right if we are running the Embedded Server Library, where the default dir of the process is not necessarily the MySQL datadir
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 for a bug with LEAST() in WHERE clause
ha_innodb.cc:
Fix for a configure bug
multi_update.result, multi_update.test:
Fix for the update with NULL's in the result set
sql_update.cc:
Fix for the update with NULL's in the result set
Fix for the update with NULL's in the result set
Fix for the update with NULL's in the result set
Since the mysql interactive client or some other phase in communication cuts > 64 kB strings to very short, restrict the output of SHOW INNODB STATUS to at most 60 kB
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
In ORDER BY MySQL seems to set the key read flag also in the case where the primary key contains only a prefix of a column - not the whole column; to prevent potential bugs retrieve the whole column if the index contains a prefix of it
Cleanup
ha_innodb.cc, data0type.h:
Make sure non-latin1 users can downgrade from 4.0.14 to an earlier version if they have not created DATA_BLOB column prefix indexes
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
Remove accidenatlly committed debug printfs when query cache is used
sql_update.cc, sql_load.cc, sql_insert.cc, sql_delete.cc:
For the transactional query cache algorithm to work we must invalidate the query cache in INSERT/DELETE/UPDATE before writing to the binlog or calling ha_autocommit_... Note that binlog writing may also call commit. The crucial thing is that the transaction which modified data must not be committed BEFORE the query cache is invalidated.
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
