Fix bug: if the user created a prefix column key on a fixed length char column, then InnoDB claimed in CHECK TABLE that the table is corrupt
dict0dict.c:
Fix bug 1151: if the user created a prefix column primary key on a fixed length char column, then InnoDB crashed in a simple SELECT
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
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
Merge InnoDB-4.0.7. Support for ON UPDATE CASCADE
sql_select.cc:
Remove superfluous prints to .err log when a locking SELECT fails to a deadlock or a lock wait timeout
Merge InnoDB-4.0.5: new isolation levels READ COMMITTED and READ UNCOMMITTED now supported, selective deadlock resolution
mysqld.cc:
Change MySQL default isolation level to REPEATABLE READ; note that InnoDB has always had that default, and BDB and MyISAM always run at SERIALIZABLE level anyway
ha_innodb.cc Remove gaps in auto-inc in multi-row inserts, more space for foreign key listings in SHOW TABLE STATUS, move resetting of active_trx to amore logical place
dict0dict.h Remove gaps from auto-inc sequence if errors in multi-row insert
dict0dict.c Remove gaps from auto-inc sequence if errors in multi-row insert
Made a some new buffers thread specific and changeable.
Resize of key_buffer.
AUTO_COMMIT -> AUTOCOMMIT
Fixed mutex bug in DROP DATABASE
Fixed bug when using auto_increment as second part of a key where first part could include NULL.
Split handler->extra() to extra() and extra_opt() to be able to support thread specific buffers.
Don't write message to error log when slave reconnects becasue of timeout.
Fixed possible update problem when using DELETE/UPDATE on small tables
(In some cases we used index even if table scanning would be better)
A lot of minior code cleanups
Do less statistics calculations for tables
dict0mem.h, row0mysql.c:
Make calculation of new statistics less frequent, because the statistics in 3.23.44 involves many random disk reads
Fix a bug in insert buffer B-tree upper levels; probably caused the crash by B.Fitzpatrick
buf0flu.c:
Fix a bug in previous change
A small optimization for LRU flushes to avoid losing hot pages from the buffer pool
Made innodb to compile more cleanly with debugging options
enabled. Fixed a few bugs and found a few possible bugs, which
I hope Heikki will check. Comments needs to be fixed too. Some
while() functions should be changed to do ... until for documenting
purposes, because some of them must and will be processed at least
once, or a variable would be used uninitialized.
