2010-03-18 The InnoDB Team
* CMakeLists.txt:
Fix Bug#52102 InnoDB Plugin shows performance drop compared to
InnoDB (Windows)
2010-03-18 The InnoDB Team
* buf0buf.ic:
When comparing the time of the first access to a block against
innodb_old_blocks_time, use 32-bit arithmetics. The comparison was
incorrect on 64-bit systems.
2010-03-11 The InnoDB Team
* buf0buf.h, buf0buf.ic:
Fix and clarify the latching of some buf_block_t members.
Note that check_index_page_at_flush is not protected by any mutex.
Note and assert that lock_hash_val is protected by the rw-latch.

Fix Bug#51378 Init 'ref_length' to correct value, in case an out
of bound MySQL primary_key
2010-03-10 The InnoDB Team
* log/log0recv.c:
Remove a bogus assertion about page numbers exceeding 0x90000000
in the redo log. Abort when encountering a corrupted redo log
record, unless innodb_force_recovery is set.
2010-03-09 The InnoDB Team
* handler/ha_innodb.cc:
Make SHOW ENGINE INNODB MUTEX STATUS display SUM(os_waits)
for the buffer pool block mutexes and locks.
2010-03-08 The InnoDB Team
* fil/fil0fil.c:
Fix ALTER TABLE ... IMPORT TABLESPACE of compressed tables.
2010-03-03 The InnoDB Team
* handler/handler0alter.cc, innodb-index.result, innodb-index.test,

Fix Bug#49535 Available memory check slows down crash
recovery tens of times
2010-02-09 The InnoDB Team
* buf/buf0buf.c:
Fix Bug#38901 InnoDB logs error repeatedly when trying to load
page into buffer pool
2010-02-09 The InnoDB Team
* srv/srv0srv.c:
Let the master thread sleep if the amount of work to be done is
calibrated as taking less than a second.
2010-02-04 The InnoDB Team
* btr/btr0btr.c, btr/btr0cur.c, btr/btr0pcur.c, buf/buf0buf.c,
include/btr0btr.h, include/btr0cur.h, include/btr0pcur.h,
include/btr0pcur.ic, include/buf0buf.h, row/row0ins.c, row/row0sel.c:
Pass the file name and line number of the caller of the
b-tree cursor functions to the buffer pool requests, in order
to make the latch diagnostics more accurate.

* buf/buf0lru.c:
Fix Bug#35077 Very slow DROP TABLE (ALTER TABLE, OPTIMIZE TABLE)
on compressed tables
2010-02-03 The InnoDB Team
* handler/ha_innodb.cc, include/row0mysql.h, row/row0mysql.c:
Clean up CHECK TABLE error handling.
2010-02-01 The InnoDB Team
* handler/ha_innodb.cc, mysql-test/innodb-autoinc.test,
mysql-test/innodb-autoinc.result,
mysql-test/innodb-autoinc-44030.test,
mysql-test/innodb-autoinc-44030.result:
Fix Bug#49497 Error 1467 (ER_AUTOINC_READ_FAILED) on inserting
a negative value
2010-01-27 The InnoDB Team
* include/row0mysql.h, log/log0recv.c, row/row0mysql.c:
Drop temporary tables at startup.
This addresses the third aspect of
Bug#41609 Crash recovery does not work for InnoDB temporary tables.
2010-01-21 The InnoDB Team
* buf/buf0buf.c:
Do not merge buffered inserts to compressed pages before
the redo log has been applied in crash recovery.
2010-01-13 The InnoDB Team
* row/row0sel.c:
On the READ UNCOMMITTED isolation level, do not attempt to access
a clustered index record that has been marked for deletion. The
built-in InnoDB in MySQL 5.1 and earlier would attempt to retrieve
a previous version of the record in this case.
2010-01-13 The InnoDB Team
* buf/buf0buf.c:
When disabling the adaptive hash index, check the block state
before checking block->is_hashed, because the latter may be
uninitialized right after server startup.
2010-01-12 The InnoDB Team
* handler/ha_innodb.cc, handler/ha_innodb.h:
Fix Bug#46193 crash when accessing tables after enabling
innodb_force_recovery option
2010-01-12 The InnoDB Team
* row/row0mysql.c:
Fix Bug#49238 Creating/Dropping a temporary table while at 1023
transactions will cause assert.
2009-12-02 The InnoDB Team
* srv/srv0start.c:
Display the zlib version number at startup.
InnoDB compressed tables use zlib, and the implementation depends
on the zlib function compressBound(), whose definition was slightly
changed in zlib version 1.2.3.1 in 2006. MySQL bundles zlib 1.2.3
from 2005, but some installations use a more recent zlib.
2009-11-30 The InnoDB Team
* dict/dict0crea.c, dict/dict0mem.c, dict/dict0load.c,
dict/dict0boot.c, fil/fil0fil.c, handler/ha_innodb.cc,
include/dict0mem.h, row/row0mysql.c:
Fix the bogus warning messages for non-existing temporary
tables that were reported in
Bug#41609 Crash recovery does not work for InnoDB temporary tables.
The actual crash recovery bug was corrected on 2009-04-29.
2009-11-27 The InnoDB Team
InnoDB Plugin 1.0.6 released
2009-11-20 The InnoDB Team

mysql-test/innodb.test, mysql-test/innodb_bug44369.result,
mysql-test/innodb_bug44369.test, mysql-test/patches/innodb-index.diff,
row/row0mysql.c:
Report duplicate table names to the client connection, not to the
error log.
2009-11-12 The InnoDB Team
* handler/ha_innodb.cc, include/db0err.h, row/row0merge.c,
row/row0mysql.c:
Allow CREATE INDEX to be interrupted.
Also, when CHECK TABLE is interrupted, report ER_QUERY_INTERRUPTED.
2009-11-11 The InnoDB Team

become inaccurate
2009-10-26 The InnoDB Team
* row/row0ins.c:
When allocating a data tuple, zero out the system fields in order

* include/page0page.ic:
Fix Bug#47058 Failure to compile innodb_plugin on solaris 10u7 + spro
cc/CC 5.10
2009-10-13 The InnoDB Team
* buf/buf0flu.c:
Call fsync() on datafiles after a batch of pages is written to disk
even when skip_innodb_doublewrite is set.
2009-10-05 The InnoDB Team
* buf/buf0buf.c:
Do not invalidate buffer pool while an LRU batch is active. Added code
to buf_pool_invalidate() to wait for the running batches to finish.
2009-10-01 The InnoDB Team
* handler/ha_innodb.cc:
Fix Bug#47763 typo in error message: Failed to open table %s after %lu
attemtps.
2009-10-01 The InnoDB Team
* fsp/fsp0fsp.c, row/row0merge.c:
Clean up after a crash during DROP INDEX. When InnoDB crashes
while dropping an index, ensure that the index will be completely
dropped during crash recovery. The MySQL .frm file may still
contain the dropped index, but there is little that we can do
about it.
2009-09-28 The InnoDB Team
* handler/ha_innodb.cc:
When a secondary index exists in the MySQL .frm file but not in
the InnoDB data dictionary, return an error instead of letting an
assertion fail in index_read.
2009-09-28 The InnoDB Team
* btr/btr0btr.c, buf/buf0buf.c, include/page0page.h,
include/page0zip.h, page/page0cur.c, page/page0page.c,
page/page0zip.c:
Do not write to PAGE_INDEX_ID when restoring an uncompressed page
after a compression failure. The field should only be written
when creating a B-tree page. This fix addresses a race condition
in a debug assertion.
2009-09-28 The InnoDB Team
* fil/fil0fil.c:
Try to prevent the reuse of tablespace identifiers after InnoDB
has crashed during table creation. Also, refuse to start if files
with duplicate tablespace identifiers are encountered.
2009-09-25 The InnoDB Team
* include/os0file.h, os/os0file.c:

* handler/ha_innodb.cc, mysql-test/innodb-consistent-master.opt,
mysql-test/innodb-consistent.result,
mysql-test/innodb-consistent.test:
Fix Bug#37232 Innodb might get too many read locks for DML with
repeatable-read
2009-09-19 The InnoDB Team
* fsp/fsp0fsp.c:
Fix Bug#31183 Tablespace full problems not reported in error log,
error message unclear
2009-09-17 The InnoDB Team
* mysql-test/innodb-zip.result, mysql-test/innodb-zip.test:
Make the test pass with zlib 1.2.3.3. Apparently, the definition
of compressBound() has changed between zlib versions, and the
maximum record size of a table with 1K compressed page size has
been reduced by one byte. This is an arbitrary test. In practical
applications, for good write performance, the compressed page size
should be chosen to be bigger than the absolute minimum.
2009-09-16 The InnoDB Team
* handler/ha_innodb.cc:

2009-09-02 The InnoDB Team
* include/lock0lock.h, include/row0mysql.h, lock/lock0lock.c,
row/row0mysql.c:
Fix a regression introduced by the fix for MySQL bug#26316. We check
whether a transaction holds any AUTOINC locks before we acquire
the kernel mutex and release those locks.
2009-08-27 The InnoDB Team
* dict/dict0dict.c, include/dict0dict.h,
mysql-test/innodb_bug44571.result, mysql-test/innodb_bug44571.test:
Fix Bug#44571 InnoDB Plugin crashes on ADD INDEX
2009-08-27 The InnoDB Team
* row/row0merge.c:
Fix a bug in the merge sort that can corrupt indexes in fast index
creation. Add some consistency checks. Check that the number of
records remains constant in every merge sort pass.
2009-08-27 The InnoDB Team
* buf/buf0buf.c, buf/buf0lru.c, buf/buf0rea.c, handler/ha_innodb.cc,
include/buf0buf.h, include/buf0buf.ic, include/buf0lru.h,
include/ut0ut.h, ut/ut0ut.c:
Make it possible to tune the buffer pool LRU eviction policy to be
more resistant against index scans. Introduce the settable global
variables innodb_old_blocks_pct and innodb_old_blocks_time for
controlling the buffer pool eviction policy. The parameter
innodb_old_blocks_pct (5..95) controls the desired amount of "old"
blocks in the LRU list. The default is 37, corresponding to the
old fixed ratio of 3/8. Each time a block is accessed, it will be
moved to the "new" blocks if its first access was at least
innodb_old_blocks_time milliseconds ago (default 0, meaning every
block). The idea is that in index scans, blocks will be accessed
a few times within innodb_old_blocks_time, and they will remain in
the "old" section of the LRU list. Thus, when innodb_old_blocks_time
is nonzero, blocks retrieved for one-time index scans will be more
likely candidates for eviction than blocks that are accessed in
random patterns.
2009-08-26 The InnoDB Team

* buf/buf0rea.c, handler/ha_innodb.cc, include/srv0srv.h,
srv/srv0srv.c:
Change the read ahead parameter name to innodb_read_ahead_threshold.
Change the meaning of this parameter to signify the number of pages
that must be sequentially accessed for InnoDB to trigger a readahead
request.
2009-07-20 The InnoDB Team

srv/srv0srv.c:
Implement the adaptive flushing of dirty pages, which uses
a heuristics based flushing rate of dirty pages to avoid IO
bursts at checkpoint. Expose new configure knob
innodb_adaptive_flushing to control whether the new flushing
algorithm should be used.
2009-07-07 The InnoDB Team
* handler/ha_innodb.cc, include/srv0srv.h, log/log0log.c,
srv/srv0srv.c:

Fix a race condition when reading buf_fix_count.
Currently, it is not being protected by the buffer pool mutex,
but by the block mutex.
2009-06-29 The InnoDB Team
* handler/handler0alter.cc:
Start the user transaction prebuilt->trx if it was not started
before adding or dropping an index. Without this fix, the

2009-06-25 The InnoDB Team
* dict/dict0dict.c:
When an index column cannot be found in the table during index

* handler/ha_innodb.cc, include/os0file.h, include/srv0srv.h,
os/os0file.c, srv/srv0srv.c, srv/srv0start.c:
Enable functionality to have multiple background IO helper threads.
Expose new configure knobs innodb_read_io_threads and
innodb_write_io_threads and deprecate innodb_file_io_threads (this
parameter was relevant only on windows). Internally this allows
multiple segments for read and write IO request arrays where one
thread works on one segment.
2009-06-05 The InnoDB Team
* buf/buf0lru.c, buf/buf0rea.c, handler/ha_innodb.cc,
include/srv0srv.h, srv/srv0srv.c:
Fix a bug in linear read ahead:
1) Take into account access pattern when deciding whether or not to
do linear read ahead.
2) Expose a knob innodb_read_ahead_factor = [0-64] default (8),
dynamic, global to control linear read ahead behavior. This is the
value of the number of pages that InnoDB will tolerate within a
64 page extent even if they are accessed out of order or have
not been accessed at all. This number (which varies from 0 to 64)
is indicative of the slack that we have when deciding about linear
readahead.
3) Disable random read ahead. Keep the code for now.

Skip the undo log size check when creating REDUNDANT and COMPACT
tables. In ROW_FORMAT=DYNAMIC and ROW_FORMAT=COMPRESSED, column
prefix indexes require that prefixes of externally stored columns
be written to the undo log. This may make the undo log record
bigger than the record on the B-tree page. The maximum size of an
undo log record is the page size. That must be checked for, in
dict_index_add_to_cache(). However, this restriction must not
be enforced on REDUNDANT or COMPACT tables.

When the server crashes while freeing an externally stored column
of a compressed table, the BTR_EXTERN_LEN field in the BLOB

* btr/btr0btr.c, include/page0zip.h, page/page0zip.c, include/univ.i:
When a B-tree node of a compressed table is split or merged, the
compression may fail. In this case, the entire compressed page
will be copied and the excess records will be deleted. However,
page_zip_copy(), now renamed to page_zip_copy_recs(), copied too
many fields in the page header, overwriting PAGE_BTR_SEG_LEAF and
PAGE_BTR_SEG_TOP when splitting the B-tree root. This caused
corruption of compressed tables. Furthermore, the lock table and
the adaptive hash index would be corrupted, because we forgot to
update them when invoking page_zip_copy_recs().
Introduce the symbol UNIV_ZIP_DEBUG for triggering the copying of
compressed pages more often, for debugging purposes.

* handler/handler0alter.cc, include/row0merge.h, row/row0merge.c,

Fix some locking issues, mainly in fast index creation. The
InnoDB data dictionary cache should be latched whenever a
transaction is holding locks on any data dictionary tables.
Otherwise, lock waits or deadlocks could occur. Furthermore, the
data dictionary transaction must be committed (and the locks
released) before the data dictionary latch is released.

When dropping a table, hold the data dictionary latch until the
transaction has been committed. The data dictionary latch is
supposed to prevent lock waits and deadlocks in the data
dictionary tables. Due to this bug, DROP TABLE could cause a
deadlock or hang. Note that because of Bug#33650 and Bug#39833,
MySQL may also drop a (temporary) table when executing CREATE INDEX
or ALTER TABLE ... ADD INDEX.

When creating an index in innodb_strict_mode, check that the
maximum record size will never exceed the B-tree page size limit.
For uncompressed tables, there should always be enough space for
two records in an empty B-tree page. For compressed tables, there
should be enough space for storing two node pointer records or one
data record in an empty page in uncompressed format.
The purpose of this check is to guarantee that INSERT or UPDATE
will never fail due to too big record size.

Prevent infinite B-tree page splits in compressed tables by
ensuring that there will always be enough space for two node
pointer records in an empty B-tree page. Also, require that at
least one data record will fit in an empty compressed page. This
will reduce the maximum size of records in compressed tables.
