	columns

2008-10-30	The InnoDB Team

	* handler/ha_innodb.cc, handler/handler0vars.h,
	handler/win_delay_loader.cc, mysql-test/innodb_bug40360.result,
	mysql-test/innodb_bug40360.test:
	Fix Bug#40360 Binlog related errors with binlog off

2008-10-29	The InnoDB Team

	* include/data0type.ic:
	Fix Bug#40369 dtype_get_sql_null_size() returns 0 or 1, not the size

2008-10-29	The InnoDB Team

	* handler/ha_innodb.cc, include/srv0srv.h, srv/srv0srv.c:
	Fix Bug#38189 innodb_stats_on_metadata missing

2008-10-28	The InnoDB Team

	* CMakeLists.txt, ha_innodb.def, handler/ha_innodb.cc,
	handler/handler0alter.cc, handler/handler0vars.h, handler/i_s.cc,
	handler/win_delay_loader.cc, win-plugin/*:
	Implemented the delayloading of externals for the plugin on Windows.
	This makes it possible to build a dynamic plugin (ha_innodb.dll) on
	Windows.

2008-10-27	The InnoDB Team

	* CMakeLists.txt:
	Fix Bug#19424 InnoDB: Possibly a memory overrun of the buffer being
	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
	version 4.1, when innodb_file_per_table was implemented.
	This may fix Bug#27276 InnoDB Error: ibuf cursor restoration fails.

2008-10-22	The InnoDB Team

	* dict/dict0dict.c, dict/dict0mem.c, handler/ha_innodb.cc,
	handler/ha_innodb.h, include/dict0dict.h, include/dict0mem.h,
	row/row0mysql.c:
	Fix Bug#39830 Table autoinc value not updated on first insert
	Fix Bug#35498 Cannot get table test/table1 auto-inccounter value in

	engine" in 5.1.24 auto-inc

2008-10-22	The InnoDB Team

	* handler/ha_innodb.cc, include/row0mysql.h, row/row0mysql.c:
	Fix Bug#40224 New AUTOINC changes mask reporting of deadlock/timeout
	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
	buf_LRU_invalidate_tablespace()

2008-10-08	The InnoDB Team

	* 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.

2008-10-04	The InnoDB Team

	* handler/ha_innodb.cc, mysql-test/innodb_bug39438-master.opt,
	mysql-test/innodb_bug39438.result, mysql-test/innodb_bug39438.test:
	Fix Bug#39438 Testcase for Bug#39436 crashes on 5.1 in
	fil_space_get_latch

2008-10-04	The InnoDB Team

	* include/lock0lock.h, lock/lock0lock.c,
	mysql-test/innodb_bug38231.result, mysql-test/innodb_bug38231.test,
	row/row0mysql.c:
	Fix Bug#38231 Innodb crash in lock_reset_all_on_table() on TRUNCATE +
	LOCK / UNLOCK

2008-10-04	The InnoDB Team

	* handler/ha_innodb.cc:
	Fix Bug#35498 Cannot get table test/table1 auto-inccounter value in
	::info

2008-10-04	The InnoDB Team

	* handler/ha_innodb.cc, handler/ha_innodb.h:
	Fix Bug#37788 InnoDB Plugin: AUTO_INCREMENT wrong for compressed
	tables

2008-10-04	The InnoDB Team

	* dict/dict0dict.c, handler/ha_innodb.cc, handler/ha_innodb.h,
	include/dict0dict.h, include/dict0mem.h, row/row0mysql.c:
	Fix Bug#39830 Table autoinc value not updated on first insert

2008-10-03	The InnoDB Team

	* mysql-test/innodb-index.test, mysql-test/innodb-index.result,
	mysql-test/innodb-timeout.test, mysql-test/innodb-timeout.result,
	srv/srv0srv.c, include/srv0srv.h, handler/ha_innodb.cc,
	include/ha_prototypes.h:
	Fix Bug#36285 innodb_lock_wait_timeout is not dynamic, not per session

2008-09-19	The InnoDB Team

	* os/os0proc.c:
	Fix a memory leak on Windows. The memory leak was due to wrong
	parameters passed into VirtualFree() call. As the result, the
	call fails with Windows error 87.

2008-09-17	The InnoDB Team

	* mysql-test/innodb.result, mysql-test/innodb-zip.result,
	mysql-test/innodb-zip.test, mysql-test/innodb.test, ibuf/ibuf0ibuf.c,
	dict/dict0crea.c, dict/dict0load.c, dict/dict0boot.c,
	include/dict0dict.h, include/trx0trx.h, dict/dict0dict.c,
	trx/trx0trx.c, include/ha_prototypes.h, handler/ha_innodb.cc:
	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.

2008-09-17	The InnoDB Team

	* btr/btr0cur.c, data/data0data.c, include/page0zip.h,
	include/page0zip.ic, page/page0zip.c, mysql-test/innodb_bug36172.test:
	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.

2008-09-09	The InnoDB Team

	* mysql-test/innodb.result:
	Fix the failing innodb test by merging changes that MySQL made to
	that file (r2646.12.1 in MySQL BZR repository)

2008-08-06	The InnoDB Team

	* btr/btr0btr.c, btr/btr0cur.c, ibuf/ibuf0ibuf.c, include/btr0cur.h,
	include/trx0roll.h, include/trx0types.h, row/row0purge.c,
	row/row0uins.c, row/row0umod.c, trx/trx0roll.c:
	In the rollback of incomplete transactions after crash recovery,
	tolerate clustered index records whose externally stored columns
	have not been written.

2008-07-30	The InnoDB Team

	* trx/trx0trx.c:
	Fixes a race in recovery where the recovery thread recovering a
	PREPARED trx and the background rollback thread can both try
	to free the trx after its status is set to COMMITTED_IN_MEMORY.

2008-07-15	The InnoDB Team

	* btr/btr0sea.c, dict/dict0dict.c, include/btr0sea.h:
	Fixed a timing hole where a thread dropping an index can free the
	in-memory index struct while another thread is still using that
	structure to remove entries from adaptive hash index belonging
	to one of the pages that belongs to the index being dropped.

2008-07-04	The InnoDB Team

	* mysql-test/innodb-index.result:

	and is not calling ::add_index() anymore when adding primary index on
	non-NULL column

2008-07-01	The InnoDB Team

	* mysql-test/innodb-replace.result, mysql-test/innodb-replace.test:

	Rewrite the function innodb_plugin_init() to support parameters in
	different order (in static and dynamic InnoDB) and to support more
	parameters in the static InnoDB

2008-06-19	The InnoDB Team

	* handler/handler0alter.cc:
	Fix a bug in ::add_index() which set the transaction state to "active"
	but never restored it to the original value. This bug caused warnings
	to be printed by the rpl.rpl_ddl mysql-test.

2008-06-19	The InnoDB Team

	* mysql-test/patches:
	Add a directory which contains patches, which need to be applied to
	MySQL source in order to get some mysql-tests to succeed. The patches
	cannot be committed in MySQL repository because they are specific to
	the InnoDB plugin.
