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.

	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
