	* row/row0sel.c:
	On the READ UNCOMMITTED isolation level, do not attempt to access

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

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

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.

	* handler/ha_innodb.cc, mysql-test/innodb.result, srv/srv0srv.c:
	Change the following defaults:
	max_dirty_pages_pct: from 90 to 75, max allowed from 100 to 99
	additional_mem_pool_size: from 1 to 8 MB
	buffer_pool_size: from 8 to 128 MB
	log_buffer_size: from 1 to 8 MB
	read_io_threads/write_io_threads: from 1 to 4

2009-06-09	The InnoDB Team

	* handler/ha_innodb.cc, include/trx0trx.h, trx/trx0trx.c:
	Enable Group Commit functionality that was broken in 5.0 when
	distributed transactions were introduced.

2009-06-05	The InnoDB Team

	* 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.

2009-06-03	The InnoDB Team

	* dict/dict0dict.c, mysql-test/t/innodb_mysql.test,
	mysql-test/r/innodb_mysql.result:
	Fix Bug#39793 Foreign keys not constructed when column
	has a '#' in a comment or default value

2009-05-27	The InnoDB Team

	* Doxyfile:
	Allow the extraction of documentation from the code base with the
	Doxygen tool. Convert and add many (but not yet all) comments to
	Doxygen format.

2009-05-19	The InnoDB Team

	* btr/btr0btr.c, btr/btr0cur.c, lock/lock0lock.c,

	include/page0page.h, include/dict0dict.ic, ibuf/ibuf0ibuf.c,
	page/page0zip.c, page/page0page.c:
	Write updates of PAGE_MAX_TRX_ID to the redo log and add debug
	assertions for checking that PAGE_MAX_TRX_ID is valid on leaf
	pages of secondary indexes and the insert buffer B-tree. This bug
	could cause failures in secondary index lookups in consistent
	reads right after crash recovery.

2009-05-18	The InnoDB Team

	* btr/btr0cur.c:
	Correctly estimate the space needed on the compressed page when
	performing an update by delete-and-insert.

	log/log0recv.c:
	Fix Bug#41609 Crash recovery does not work for InnoDB temporary tables

2009-04-23	The InnoDB Team

	* row/row0mysql.c:
	When scanning indexes, report in the error log any error codes
	returned by the search function. These error codes will still be
	ignored in CHECK TABLE.

2009-04-23	The InnoDB Team

	* include/trx0types.h:
	Define the logical type names trx_id_t, roll_ptr_t, and undo_no_t
	and use them in place of dulint everywhere.

	Use the Windows Interlocked functions for atomic memory
	access.

2009-04-15	The InnoDB Team

	* mysql-test/innodb.result, mysql-test/innodb.test:
	Fix Bug#43309 Test main.innodb can't be run twice

2009-04-14	The InnoDB Team

	* CMakeLists.txt, handler/win_delay_loader.cc,
	win-plugin/win-plugin.diff:
	Remove statically linked libraries from MySQL (zlib and strings).

2009-04-11	The InnoDB Team

	* CMakeLists.txt, win-plugin/README, win-plugin/win-plugin.diff:
	Rewrite CMakeLists.txt.

2009-04-07	The InnoDB Team

	* page/page0cur.c:
	Fix Bug#43660 SHOW INDEXES/ANALYZE does NOT update cardinality for
	indexes of InnoDB table

2009-04-06	The InnoDB Team

	* handler/ha_innodb.cc:
	Make the parameter innodb_change_buffering settable by the
	configuration file or mysqld command line options. Before this
	fix, the initial value specified for this parameter was ignored.

2009-04-06	The InnoDB Team

	* sync/sync0rw.c:
	Avoid a bogus failure in UNIV_SYNC_DEBUG diagnostics.

2009-04-02	The InnoDB Team

	* handler/ha_innodb.cc, include/srv0srv.h, srv/srv0srv.c:
	Add new parameter innodb_spin_wait_delay to set the maximum delay
	between polling for a spin lock.

2009-04-02	The InnoDB Team

	* dict/dict0crea.c, handler/ha_innodb.cc, handler/ha_innodb.h,

	mysql-test/innodb-index.result, mysql-test/innodb-index.test,
	row/row0merge.c, row/row0sel.c:
	In consistent reads, refuse to use newly created indexes that may
	lack history.

2009-03-25	The InnoDB Team

	* buf/buf0buf.c, handler/ha_innodb.cc, include/buf0buf.h:
	In SHOW ENGINE INNODB MUTEX do not show the status of block->mutex,
	block->lock, block->lock->mutex (if applicable) and all mutexes and
	rw-locks for which number of os-waits are zero because this can
	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:
	Remove the compile-time constant parameters of
	recv_recover_page(), recv_scan_log_recs(), and recv_sys_init().

2009-03-20	The InnoDB Team

	* data/data0type.c, handler/ha_innodb.cc, include/ha_prototypes.h:
	Declare innobase_get_at_most_n_mbchars() in ha_prototypes.h.

2009-03-20	The InnoDB Team

	* fil/fil0fil.h, fil/fil0fil.c, srv/srv0start.c:
	Add the parameter hash_size to fil_init().

2009-03-20	The InnoDB Team

	* fil/fil0fil.c:
	Refer to fil_system directly, not via local variables.

2009-03-20	The InnoDB Team

	* page/page0page.c:
	In page_validate(), always report the space id, page number and
	the name of the index when corruption is noticed.

2009-03-20	The InnoDB Team

	* include/log0log.h, include/log0log.ic, log/log0log.c:

	include/dict0dict.h, include/srv0srv.h, srv/srv0srv.c,
	page/page0page.c:
	Replace srv_sys->dummy_ind1 and srv_sys->dummy_ind2 with
	dict_ind_redundant and dict_ind_compact, which are
	initialized by dict_init().

2009-03-11	The InnoDB Team

	InnoDB Plugin 1.0.3 released

2009-03-05	The InnoDB Team

	* handler/ha_innodb.cc, mysql-test/innodb-autoinc.result,

2009-02-25	The InnoDB Team

	* handler/ha_innodb.cc, mysql-test/innodb-autoinc.result,

2009-02-23	The InnoDB Team

	* btr/btr0cur.c:
	Fix Bug#43043 Crash on BLOB delete operation

2009-02-20	The InnoDB Team

	* handler/ha_innodb.cc:
	Make innodb_use_sys_malloc=ON the default.

2009-02-20	The InnoDB Team

	* handler/ha_innodb.cc, mysql-test/innodb-autoinc.result,
	mysql-test/innodb-autoinc.test:
	Fix Bug#42400 InnoDB autoinc code can't handle floating-point columns

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
	was 8. A non-zero setting may be useful when InnoDB is showing severe
	scalability problems under multiple concurrent connections.

2009-02-10	The InnoDB Team

	* handler/ha_innodb.cc, handler/ha_innodb.h:
	Fix Bug#41676 Table names are case insensitive in locking

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.

2009-02-10	The InnoDB Team

	* btr/btr0cur.c, btr/btr0sea.c, buf/buf0buf.c, handler/ha_innodb.cc,
	include/buf0buf.ic, include/os0sync.h, include/srv0srv.h,

	srv/srv0start.c, sync/sync0arr.c, sync/sync0rw.c, sync/sync0sync.c:
	On those platforms that support it, implement the synchronization
	primitives of InnoDB mutexes and read/write locks with GCC atomic
	builtins instead of Pthreads mutexes and InnoDB mutexes. These changes
	are based on a patch supplied by Mark Callaghan of Google under a BSD
	license.

2009-01-30	The InnoDB Team

	* btr/btr0cur.c, btr/btr0sea.c, buf/buf0buf.c, handler/ha_innodb.cc,
	include/btr0sea.h, include/buf0buf.h, include/sync0sync.h,
	sync/sync0sync.c:
	Make the configuration parameter innodb_adaptive_hash_index dynamic,
	so that it can be changed at runtime.

2009-01-29	The InnoDB Team

	* 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

	* buf/buf0buf.c, include/buf0buf.h:
	Remove the unused mode BUF_GET_NOWAIT of buf_page_get_gen()

2009-01-20	The InnoDB Team

	* include/rem0rec.h, include/rem0rec.ic:
	Fix Bug#41571 MySQL segfaults after innodb recovery

2009-01-20	The InnoDB Team

	* lock/lock0lock.c:
	Fix Bug#42152 Race condition in lock_is_table_exclusive()

2009-01-14	The InnoDB Team

	* include/trx0roll.h, trx/trx0roll.c, trx/trx0trx.c:
	Fix Bug#38187 Error 153 when creating savepoints

2009-01-14	The InnoDB Team

	* dict/dict0load.c:
	Fix Bug#42075 dict_load_indexes failure in dict_load_table will
	corrupt the dictionary cache

2009-01-13	The InnoDB Team

	* buf/buf0buddy.c, dict/dict0dict.c, dict/dict0mem.c, fil/fil0fil.c,

	include/buf0buf.ic, include/dict0dict.ic, include/hash0hash.h,
	thr/thr0loc.c, trx/trx0i_s.c:
	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
	debug assertions and an explanation to buf_flush_write_block_low().

2009-01-07	The InnoDB Team

	* row/row0merge.c:
	Fix a bug in recovery when dropping temporary indexes.

2009-01-07	The InnoDB Team

	* handler/ha_innodb.cc, handler/ha_innodb.h, handler/handler0alter.cc:
	Fix Bug#41680 calls to trx_allocate_for_mysql are not consistent

2009-01-07	The InnoDB Team

	* mysql-test/innodb_bug41904.result, mysql-test/innodb_bug41904.test,
	row/row0merge.c:
	Fix Bug#41904 create unique index problem

2009-01-02	The InnoDB Team

	* handler/ha_innodb.cc, include/srv0srv.h, mem/mem0pool.c,

	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

	* btr/btr0sea.c, buf/buf0buf.c, buf/buf0lru.c, ha/ha0ha.c,
	ha/hash0hash.c, include/buf0buf.h, include/ha0ha.h, include/ha0ha.ic,
	include/hash0hash.h, include/univ.i:
	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

	* handler/ha_innodb.cc:
	Fix Bug#40386 Not flushing query cache after truncate.

2008-12-09	The InnoDB Team

	* handler/ha_innodb.cc, srv/srv0srv.c, trx/trx0trx.c:

	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.

2008-12-01	The InnoDB Team

2008-10-29	The InnoDB Team

	* handler/ha_innodb.cc, include/srv0srv.h, srv/srv0srv.c:

	* 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
	version 4.1, when innodb_file_per_table was implemented.
	This may fix Bug#27276 InnoDB Error: ibuf cursor restoration fails.

	errors

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
