Add diagnostic prints if insert buffer merge is tried to a page whose type is not an index page, try to recover from the situation by discarding the insert buffer records
Print a warning if MySQL uses a partial-field key value prefix in a search; that would not work if the search flag would happen to be HA_READ_PREFIX_LAST
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
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
Backport from 4.0: Fix a major bug in InnoDB query estimator for queries of type SELECT ... WHERE col < x and SELECT ... WHERE col > x; MySQL could pick a table scan though the result set was only a few rows in a big table
The problem yesterday in ERROR_LOCK_VIOLATION was not InnoDB Hot Backup, but some file system backup tool: add to file writes 100 retries with 1 second waits
Add diagnostic prints to determine why the 'queries inside InnoDB' might drift upwards
ha_innodb.cc:
Add more print space to SHOW INNODB STATUS; remove possible memory leak in case there is an error
Remove the warning message that mem allocation spills from the additional mem pool to the OS; this does not hit performance with modern malloc libraries
Backport bugfix from 4.0: combined log file size >= 2 GB could cause log to be written in wrong place
btr0pcur.c:
Backport bugfix from 4.0: index cursor restoration could theoretically fail
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
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
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
Backport from 4.0: Fix bug in MySQL-3.23 ORDER BY from a table with no PRIMARY KEY and where the user had added UNIQUE indexes with CREATE INDEX
pars0grm.y:
Move inclusion of math.h after univ.i also in the .y file; this fix is already done in 4.0
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
Do not let range estimator to return over 1 / 2 of total rows in table; use longlong in range estimation
btr0cur.h, ha_innobase.cc:
Use longlong in range estimation, in case there are > 4 billion rows
Fix bug: if SHOW INNODB STATUS or innodb_monitor printed several hundred transactions, the output was truncated and we forgot to release the kernel mutex
Change srv_flush_log_at_trx_commit to ulint, note that ibool is defined as ulint, so this is purely formal change
os0file.c:
Start using unbuffered i/o again in Windows because sequential read using normal i/o was 4 times slower in XP
Improve mysql-test to be more robust.
Fix that GRANT doesn't delete SSL options
Change innobase_flush_log_at_trx_commit to uint.
Don't rotate logs if we read a rotate log entry from the master.
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
Put 'last millisecond' test to make sure page checksum errors do not result from memory corruption in InnoDB
os0thread.c, configure.in:
Make sure stack size in InnoDB threads in AIX is at least 32 kB
The lexer of InnoDB to 8-bit, it was 7-bit which made it crash on table names containing char codes > 127
pars0lex.l, pars0grm.y:
Add InnoDB internal SQL interpreter grammar and lexer sources
Fixed configure problems with HPUX and openbsd
SHOW SLAVE STATUS returns empty set if slave is not initialized
SHOW MASTER STATUS returns empty set if binary logging is not enabled.
Fixed shutdown problem on Solaris.
Redefine sprintf as ut_sprintf inside InnoDB code; some old Unixes may have a pointer as the return type of sprintf
lock0lock.c:
Add safety against buffer overruns in latest deadlock info
srv0srv.c:
Add safety against buffer overruns in SHOW INNODB STATUS
os0thread.h, os0thread.c:
Fix a portability bug introduced in Windows when we changed os_thread_id_t to be the same as os_thread_t
Fixed bugs in my last changeset that made MySQL hard to compile.
Added mutex around some data that could cause table cache corruptions when using OPTIMIZE TABLE / REPAIR TABLE or automatic repair of MyISAM tables.
Added mutex around some data in the slave start/stop code that could cause THD linked list corruptions
Extended my_chsize() to allow one to specify a filler character.
Extend vio_blocking to return the old state (This made some usage of this function much simpler)
Added testing for some functions that they caller have got the required mutexes before calling the function.
Use setrlimit() to ensure that we can write core file if one specifies --core-file.
Added --slave-compressed-protocol
Made 2 the minimum length for ft_min_word_len
Added variables foreign_key_checks & unique_checks.
Less logging from replication code (if not started with --log-warnings)
Changed that SHOW INNODB STATUS requre the SUPER privilege
More DBUG statements and a lot of new code comments
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
The UNIV_DEBUG version asserted if a foreign key check failed because of a lock wait timeout
btr0cur.c:
Fix a bug: if the primary key was updated (or delete + insert) so that only the case of characters changed, we were left with a dangling adaptive hash index pointer, often causing an assertion failure in page0page.ic line 515
Portability fixes for HPUX
Rename of CHECK_LOCK to IS_FREE_LOCK
Apply lower_case_table_names also to databases
Cleanup of describe code
Don't allow \ in database names
Fix a bug: if buffer pool size > 2 GB on a 32-bit computer, we got an assertion failure because >> acted as a division operator (not as a register shift) for a wrapped-over integer value
