2009-01-13 The InnoDB Team
* include/hash0hash.h, include/dict0dict.ic, dict/dict0dict.c,
include/buf0buf.ic, buf/buf0buddy.c, trx/trx0i_s.c,
handler/ha_innodb.cc, handler/win_delay_loader.cc,
dict/dict0mem.c, ha/ha0storage.c, thr/thr0loc.c, fil/fil0fil.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
* include/buf0flu.h, include/buf0flu.ic, buf/buf0flu.c:
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, srv/srv0srv.c,
srv/srv0start.c, mem/mem0pool.c,
mysql-test/innodb-use-sys-malloc-master.opt,
mysql-test/innodb-use-sys-malloc.result,
mysql-test/innodb-use-sys-malloc.test:
Implement the configuration parameter innodb_use_sys_malloc
(false by default), for disabling InnoDB's internal memory allocator
and using system malloc/free instead.
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/row0upd.h, include/row0sel.h, pars/pars0pars.c,
row/row0upd.c, row/row0sel.c, row/row0mysql.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
* include/univ.i, include/buf0buf.h, include/hash0hash.h,
include/ha0ha.h, include/ha0ha.ic, ha/ha0ha.c, ha/hash0hash.c,
btr/btr0sea.c, buf/buf0lru.c, buf/buf0buf.c:
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
* include/fil0fil.h, include/ibuf0ibuf.h, include/ibuf0types.h,
include/ibuf0ibuf.ic, ibuf/ibuf0ibuf.c,
buf/buf0buf.c, fil/fil0fil.c, fsp/fsp0fsp.c:
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, srv/srv0srv.c, os/os0proc.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.
ha_statistics.records cannot be 0 unless the table is empty, set
to 1 instead. The original problem of Bug#29507 has been fixed in
the server.
2008-12-09 The InnoDB Team
* handler/ha_innodb.cc, srv/srv0srv.c, trx/trx0trx.c:
Fix Bug#40760 Getting database deadlocks on simultaneous inserts.
The config param innodb_thread_concurrency is dynamically set and
is read when a thread enters/exits innodb. If the value is
changed between the enter and exit time the behaviour becomes
erratic. The fix is not to use srv_thread_concurrency when
exiting, instead use the flag trx->declared_to_be_inside_innodb.
2008-12-04 The InnoDB Team
* include/mysql_addons.h, handler/mysql_addons.cc,
handler/ha_innodb.cc, trx/trx0i_s.c, win-plugin/win-plugin.diff:
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
InnoDB Plugin 1.0.2 released
2008-10-31 The InnoDB Team
* dict/dict0mem.c, include/dict0mem.h, include/lock0lock.h,

include/ut0vec.h, include/ut0vec.ic, lock/lock0lock.c,
row/row0mysql.c, trx/trx0trx.c:
Fix Bug#26316 Triggers create duplicate entries on auto-increment
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.
2008-10-23 09:33:43 +02:00
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
::info
Fix Bug#36411 "Failed to read auto-increment value from storage
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.
2008-10-23 09:33:43 +02:00
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:

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)

srv/srv0srv.c:
Add a parameter innodb_stats_sample_pages to allow users to control
the number of index dives when InnoDB estimates the cardinality of
an index (ANALYZE TABLE, SHOW TABLE STATUS etc)
2008-08-07 The InnoDB Team
* trx/trx0i_s.c:
Fix a bug that would lead to a crash if a SELECT was issued from the
INFORMATION_SCHEMA tables and there are rolling back transactions at
the same time
2008-08-06 The InnoDB Team
* btr/btr0btr.c, btr/btr0cur.c, ibuf/ibuf0ibuf.c, include/btr0cur.h,

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.
2008-07-29 The InnoDB Team
* include/trx0rec.h, row/row0purge.c, row/row0vers.c, trx/trx0rec.c:
Fix a BLOB corruption bug
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:
Fix the failing innodb-index test by adjusting the result to a new
MySQL behavior (the change occured in BZR-r2667)
2008-07-03 The InnoDB Team
