	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.

	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,

	Fix the bogus warning messages for non-existing temporary
	tables that were reported in

	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,

	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.

	* 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.

2009-08-27	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

2009-06-29	The InnoDB Team

	* buf/buf0buf.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
	creation, display additional diagnostic before an assertion failure.
	This does NOT fix Bug#44571 InnoDB Plugin crashes on ADD INDEX,
	but it helps understand the reason of the crash.

	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

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.

	In SHOW ENGINE INNODB MUTEX do not show the status of block->mutex,
	block->lock, block->lock->mutex (if applicable) and all mutexes and

	be overwhelming particularly when the buffer pool is very large.

2009-03-20	The InnoDB Team

	* buf/buf0buf.c, include/log0recv.h, log/log0recv.c:

2009-02-18	The InnoDB Team

	* include/ut0mem.h, os/os0proc.c, ut/ut0mem.c:
	Protect ut_total_allocated_memory with ut_list_mutex in
	os_mem_alloc_large() and os_mem_free_large(). The lack of this mutex
	protection could cause an assertion failure during fast index
	creation. Also, add UNIV_MEM_ALLOC and UNIV_MEM_FREE instrumentation
	to os_mem_alloc_large() and os_mem_free_large(), so that Valgrind can
	detect more errors.

2009-02-11	The InnoDB Team

	* handler/ha_innodb.cc:
	Make innodb_thread_concurrency=0 the default. The old default value

2009-02-10	The InnoDB Team

	* mem/mem0dbg.c, mem/mem0mem.c, mem/mem0pool.c:
	When innodb_use_sys_malloc is set, ignore
	innodb_additional_mem_pool_size, because nothing will be allocated
	from mem_comm_pool.

2009-02-10	The InnoDB Team

	* ut/ut0mem.c:
	Map ut_malloc_low(), ut_realloc(), and ut_free() directly to malloc(),
	realloc(), and free() when innodb_use_sys_malloc is set. As a side
	effect, ut_total_allocated_memory ("Total memory allocated" in the
	"BUFFER POOL AND MEMORY" section of SHOW ENGINE INNODB STATUS) will
	exclude any memory allocated by these functions when
	innodb_use_sys_malloc is set.

	* handler/ha_innodb.cc, ibuf/ibuf0ibuf.c, include/ibuf0ibuf.h,
	include/ibuf0ibuf.ic:
	Implement the settable global variable innodb_change_buffering,
	with the allowed values 'none' and 'inserts'. The default value
	'inserts' enables the buffering of inserts to non-unique secondary
	index trees when the B-tree leaf page is not in the buffer pool.

2009-01-27	The InnoDB Team

	* buf/buf0lru.c:
	Fix a race condition in buf_LRU_invalidate_tablespace(): The
	compressed page size (zip_size) was read while the block descriptor
	was no longer protected by a mutex. This could lead to corruption
	when a table is dropped on a busy system that contains compressed
	tables.

2009-01-26	The InnoDB Team

	* btr/btr0sea.c, buf/buf0buf.c, include/buf0buf.h, include/buf0buf.ic,
	include/mtr0log.ic, include/row0upd.ic, mtr/mtr0mtr.c:
	Implement buf_block_align() with pointer arithmetics, as it is in the
	built-in InnoDB distributed with MySQL. Do not acquire the buffer pool
	mutex before buf_block_align(). This removes a scalability bottleneck
	in the adaptive hash index lookup. In CHECK TABLE, check that
	buf_pool->page_hash is consistent with buf_block_align().

2009-01-23	The InnoDB Team

	* btr/btr0sea.c:
	Fix Bug#42279 Race condition in btr_search_drop_page_hash_when_freed()

2009-01-23	The InnoDB Team

	Add the parameter ASSERTION to HASH_SEARCH() macro, and use it for
	light validation of the traversed items in hash table lookups when
	UNIV_DEBUG is enabled.

2009-01-09	The InnoDB Team

	* buf/buf0flu.c, include/buf0flu.h, include/buf0flu.ic:
	Remove unused code from the functions
	buf_flush_insert_into_flush_list() and
	buf_flush_insert_sorted_into_flush_list().

2009-01-09	The InnoDB Team

	* buf/buf0flu.c:
	Simplify the functions buf_flush_try_page() and buf_flush_batch(). Add

	mysql-test/innodb-use-sys-malloc.result,
	mysql-test/innodb-use-sys-malloc.test, srv/srv0srv.c, srv/srv0start.c:
	Implement the configuration parameter innodb_use_sys_malloc (false by
	default), for disabling InnoDB's internal memory allocator and using
	system malloc/free instead. The "BUFFER POOL AND MEMORY" section of
	SHOW ENGINE INNODB STATUS will report "in additional pool allocated
	allocated 0" when innodb_use_sys_malloc is set.

2008-12-30	The InnoDB Team

	* btr/btr0btr.c:
	When setting the PAGE_LEVEL of a compressed B-tree page from or to 0,
	compress the page at the same time. This is necessary, because the
	column information stored on the compressed page will differ between
	leaf and non-leaf pages. Leaf pages are identified by PAGE_LEVEL=0.
	This bug can make InnoDB crash when all rows of a compressed table are
	deleted.

2008-12-17	The InnoDB Team

	* include/row0sel.h, include/row0upd.h, pars/pars0pars.c,
	row/row0mysql.c, row/row0sel.c, row/row0upd.c:
	Remove update-in-place select from the internal SQL interpreter. It
	was only used for updating the InnoDB internal data dictionary when
	renaming or dropping tables. It could have caused deadlocks when
	acquiring latches on insert buffer bitmap pages.

2008-12-17	The InnoDB Team

	Introduce the preprocessor symbol UNIV_AHI_DEBUG for enabling adaptive
	hash index debugging independently of UNIV_DEBUG.

2008-12-16	The InnoDB Team

	* btr/btr0cur.c:
	Do not update the free bits in the insert buffer bitmap when inserting
	or deleting from the insert buffer B-tree. Assert that records in the
	insert buffer B-tree are never updated.

2008-12-12	The InnoDB Team

	* buf/buf0buf.c, fil/fil0fil.c, fsp/fsp0fsp.c, ibuf/ibuf0ibuf.c,
	include/fil0fil.h, include/ibuf0ibuf.h, include/ibuf0ibuf.ic,
	include/ibuf0types.h:
	Clean up the insert buffer subsystem so that only one insert
	buffer B-tree exists.
	Originally, there were provisions in InnoDB for multiple insert
	buffer B-trees, apparently one for each tablespace.
	When Heikki Tuuri implemented multiple InnoDB tablespaces in
	MySQL/InnoDB 4.1, he made the insert buffer live only in the
	system tablespace (space 0) but left the provisions in the code.

2008-12-11	The InnoDB Team

	* include/srv0srv.h, os/os0proc.c, srv/srv0srv.c:
	Fix the issue that the InnoDB plugin fails if innodb_buffer_pool_size
	is defined bigger than 4096M on 64-bit Windows. This bug should not
	have affected other 64-bit systems.

2008-12-09	The InnoDB Team

	Remove dependencies to MySQL internals (defining MYSQL_SERVER).

2008-12-02	The InnoDB Team

	* page/page0cur.c:
	When allocating space for a record from the free list of previously
	purged records, zero out the DB_TRX_ID and DB_ROLL_PTR of the purged
	record if the new record would not overwrite these fields. This fixes
	a harmless content mismatch reported by page_zip_validate().

2008-12-02	The InnoDB Team

	* row/row0merge.c:
	Replace the WHILE 1 with WHILE 1=1 in the SQL procedure, so that the
	loop will actually be entered and temporary indexes be dropped during
	crash recovery.

	freed (64-bit Visual C)

2008-10-23	The InnoDB Team

	* ibuf/ibuf0ibuf.c:
	ibuf_delete_rec(): When the cursor to the insert buffer record
	cannot be restored, do not complain if the tablespace does not
	exist, because the insert buffer record may have been discarded by
	some other thread. This bug has existed in MySQL/InnoDB since

2008-10-16	The InnoDB Team

	* dict/dict0dict.c, mysql-test/innodb-index.result,
	mysql-test/innodb-index.test:
	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.

2008-10-15	The InnoDB Team

	* btr/btr0cur.c, include/btr0cur.h, row/row0ext.c, row/row0sel.c,
	row/row0upd.c:
	When the server crashes while freeing an externally stored column
	of a compressed table, the BTR_EXTERN_LEN field in the BLOB
	pointer will be written as 0. Tolerate this in the functions that
	deal with externally stored columns. This fixes problems after
	crash recovery, in the rollback of incomplete transactions, and in
	the purge of delete-marked records.

2008-10-15	The InnoDB Team

	* 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.

2008-10-10	The InnoDB Team

	* handler/handler0alter.cc, include/row0merge.h, row/row0merge.c,
	row/row0mysql.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.

	ha_innobase::add_index(): Lock the data dictionary before renaming
	or dropping the created indexes, because neither operation will
	commit the data dictionary transaction.

	ha_innobase::final_drop_index(): Commit the transactions before
	unlocking the data dictionary.

2008-10-09	The InnoDB Team

	* buf/buf0lru.c:
	Fix Bug#39939 DROP TABLE/DISCARD TABLESPACE takes long time in

	* dict/dict0crea.c, trx/trx0roll.c, include/row0mysql.h,
	row/row0merge.c, row/row0mysql.c:
	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
