message:
Bug#989: If DROP TABLE while there's an active transaction, wrong binlog order
WL#4284: Transactional DDL locking
Currently the MySQL server does not keep metadata locks on
schema objects for the duration of a transaction, thus failing
to guarantee the integrity of the schema objects being used
during the transaction and to protect then from concurrent
DDL operations. This also poses a problem for replication as
a DDL operation might be replicated even thought there are
active transactions using the object being modified.
The solution is to defer the release of metadata locks until
a active transaction is either committed or rolled back. This
prevents other statements from modifying the table for the
entire duration of the transaction. This provides commitment
ordering for guaranteeing serializability across multiple
transactions.
- Incompatible change:
If MySQL's metadata locking system encounters a lock conflict,
the usual schema is to use the try and back-off technique to
avoid deadlocks -- this schema consists in releasing all locks
and trying to acquire them all in one go.
But in a transactional context this algorithm can't be utilized
as its not possible to release locks acquired during the course
of the transaction without breaking the transaction commitments.
To avoid deadlocks in this case, the ER_LOCK_DEADLOCK will be
returned if a lock conflict is encountered during a transaction.
Let's consider an example:
A transaction has two statements that modify table t1, then table
t2, and then commits. The first statement of the transaction will
acquire a shared metadata lock on table t1, and it will be kept
utill COMMIT to ensure serializability.
At the moment when the second statement attempts to acquire a
shared metadata lock on t2, a concurrent ALTER or DROP statement
might have locked t2 exclusively. The prescription of the current
locking protocol is that the acquirer of the shared lock backs off
-- gives up all his current locks and retries. This implies that
the entire multi-statement transaction has to be rolled back.
- Incompatible change:
FLUSH commands such as FLUSH PRIVILEGES and FLUSH TABLES WITH READ
LOCK won't cause locked tables to be implicitly unlocked anymore.
All committed result differences have either been verified by me or copied from Oracle's provided
results (storage/innodb_plugin/mysql-test/*.result, storage/innodb_plugin/mysql-test/patches).

branches/5.1: Fix bug#35537 - Innodb doesn't increment handler_update
and handler_delete
Add the calls to ha_statistic_increment() in ha_innobase::delete_row()
and ha_innobase::update_row().
Problem: Many test cases don't clean up after themselves (fail
to drop tables or fail to reset variables). This implies that:
(1) check-testcase in the new mtr that currently lives in
5.1-rpl failed. (2) it may cause unexpected results in
subsequent tests.
Fix: make all tests clean up.
Also: cleaned away unnecessary output in rpl_packet.result
Also: fixed bug where rpl_log called RESET MASTER with a running
slave. This is not supposed to work.
Also: removed unnecessary code from rpl_stm_EE_err2 and made it
verify that an error occurred.
Also: removed unnecessary code from rpl_ndb_ctype_ucs2_def.
Bug#37531, Bug#36941, Bug#36941, Bug#36942, Bug#38185.
Also include test case from Bug 34300 which was left out from earlier snapshot
(5.1-ss2387).
Also include fix for Bug #29507, "TRUNCATE shows to many rows effected", since
the fix for Bug 37531 depends on it.
partition is corrupt
The main problem was that ALTER TABLE t ANALYZE/CHECK/OPTIMIZE/REPAIR
PARTITION took another code path (over mysql_alter_table instead of
mysql_admin_table) which differs in two ways:
1) alter table opens the tables in a different way than admin tables do
resulting in returning with error before it tried the command
2) alter table does not start to send any diagnostic rows to the client
which the lower admin functions continue to use -> resulting in
assertion crash
The fix:
Remapped ALTER TABLE t ANALYZE/CHECK/OPTIMIZE/REPAIR PARTITION to use
the same code path as ANALYZE/CHECK/OPTIMIZE/REPAIR TABLE t.
Adding check in mysql_admin_table to setup the partition list for
which partitions that should be used.
Partitioned tables will still not work with
REPAIR TABLE/PARTITION USE_FRM, since that requires moving partitions
to tables, REPAIR TABLE t USE_FRM, and check that the data still
fulfills the partitioning function and then move the table back to
being a partition.
NOTE: I have removed the following functions from the handler
interface:
analyze_partitions, check_partitions, optimize_partitions,
repair_partitions
Since they are not longer needed.

or incorrect.
For better conformance with standard, truncation procedure of CHAR columns
has been changed to ignore truncation of trailing whitespace characters
(note has been removed).
Finally, for columns with non-binary charsets:
1. CHAR(N) columns silently ignore trailing whitespace truncation;
2. VARCHAR and TEXT columns issue Note about truncation.
BLOBs and other columns with BINARY charset are unaffected.
Fixes:
- Bug #34920: auto_increment resets to 1 on foreign key creation
We need to use/inherit the passed in autoinc counter for ALTER TABLE
statements too.
Fixes the following bugs:
- Bug #33349: possible race condition revolving around data dictionary and repartitioning
Introduce retry/sleep logic as a workaround for a transient bug
where ::open fails for partitioned tables randomly if we are using
one file per table.
- Bug #34053: normal users can enable innodb_monitor logging
In CREATE TABLE and DROP TABLE check whether the table in question is one
of the magic innodb_monitor tables and whether the user has enough rights
to mess with it before doing anything else.
- Bug #22868: 'Thread thrashing' with > 50 concurrent conns under an upd-intensive workloadw
- Bug #29560: InnoDB >= 5.0.30 hangs on adaptive hash rw-lock 'waiting for an X-lock'
This is a combination of changes that forward port the scalability fix applied to 5.0
through r1001.
It reverts changes r149 and r122 (these were 5.1 specific changes made in lieu of
scalability fix of 5.0)
Then it applies r1001 to 5.0 which is the original scalability fix.
Finally it applies r2082 which fixes an issue with the original fix.
- Bug #30930: Add auxiliary function to retrieve THD::thread_id
Add thd_get_thread_id() function. Also make check_global_access() function
visible to InnoDB under INNODB_COMPATIBILITY_HOOKS #define.
Server handles truncation for assignment of too-long values
into CHAR/VARCHAR/TEXT columns in a different ways when the
truncated characters are spaces:
1. CHAR(N) columns silently ignore end-space truncation;
2. TEXT columns post a truncation warning/error in the
non-strict/strict mode.
3. VARCHAR columns always post a truncation note in
any mode.
Space truncation processing has been synchronised over
CHAR/VARCHAR/TEXT columns: current behavior of VARCHAR
columns has been propagated as standard.
Binary-encoded string/BLOB columns are not affected.
Fixes:
Bug #18942: DROP DATABASE does not drop an orphan FOREIGN KEY constraint
Fix Bug#18942 by dropping all foreign key constraints at the end of
DROP DATABASE. Usually, by then, there are no foreign constraints
left because all of them are dropped when the relevant tables are
dropped. This code is to ensure that any orphaned FKs are wiped too.
Bug #29157: UPDATE, changed rows incorrect
Return HA_ERR_RECORD_IS_THE_SAME from ha_innobase::update_row() if no
columns were updated.
Bug #32440: InnoDB free space info does not appear in SHOW TABLE STATUS or I_S
Put information about the free space in a tablespace in
INFORMATION_SCHEMA.TABLES.DATA_FREE. This information was previously
available in INFORMATION_SCHEMA.TABLES.TABLE_COMMENT, but MySQL has
removed it from there recently.
The stored value is in kilobytes.
This can be considered as a permanent workaround to
http://bugs.mysql.com/32440. "Workaround" becasue that bug is about the
data missing from TABLE_COMMENT and this is actually not solved.
Default values of variables were not subject to upper/lower bounds
and step, while setting variables was. Bounds and step are also
applied to defaults now; defaults are corrected quietly, values
given by the user are corrected, and a correction-warning is thrown
as needed. Lastly, very large values could wrap around, starting
from 0 again. They are bounded at the maximum value for the
respective data-type now if no lower maximum is specified in the
variable's definition.
and auto_increment keys
Problems:
1. ALTER TABLE ... ORDER BY... doesn't make sence if there's a
user-defined clustered index in the table.
2. using a secondary index is slower than using a clustered one
for a table scan.
Fixes:
1. raise a warning.
2. use the clustered index.
The following bugs are fixed:
Bug #31860: Server crashes after inserting into InnoDB table with auto_increment column
In the Bug 16979 fix there was an erroneous assertion that
autoincrement columns can't contain negative values. With the fix, the
autoincrement table counter is set to 0 if the maximum value read from
the autoinc column index is negative.
Fixes the following bugs:
Bug #30706: SQL thread on slave is allowed to block client queries when slave load is high
Add (innodb|innobase|srv)_replication_delay MySQL config parameter.
Bug #30888: Innodb table + stored procedure + row deletion = server crash
While adding code for the low level read of the AUTOINC value from the index,
the case for MEDIUM ints which are 3 bytes was missed triggering an
assertion.
Bug #30907: Regression: "--innodb_autoinc_lock_mode=0" (off) not same as older releases
We don't rely on *first_value to be 0 when checking whether
get_auto_increment() has been invoked for the first time in a multi-row
INSERT. We instead use trx_t::n_autoinc_rows. Initialize trx::n_autoinc_rows
inside ha_innobase::start_stmt() too.
Bug #31444: "InnoDB: Error: MySQL is freeing a thd" in innodb_mysql.test
ha_innobase::external_lock(): Update prebuilt->mysql_has_locked and
trx->n_mysql_tables_in_use only after row_lock_table_for_mysql() returns
DB_SUCCESS. A timeout on LOCK TABLES would lead to an inconsistent state,
which would cause trx_free() to print a warning.
Bug #31494: innodb + 5.1 + read committed crash, assertion
Set an error code when a deadlock occurs in semi-consistent read.
similar to bug_27716, but it was stressed on in the synopsis on that there is another
side of the artifact affecting behaviour in transaction.
Fixed with deploying multi_delete::send_error() - otherwise never called - and refining its logic
to perform binlogging job if needed.
The changeset includes the following side effects:
- added tests to check bug_23333's scenarios on the mixture of tables for multi_update;
- fixes bug@30763 with two-liner patch and a test coinciding to one added for bug_23333.
Bug #16979: AUTO_INC lock in InnoDB works a table level lock
- this is a major change in InnoDB auto-inc handling.
Bug #27950: Duplicate entry error in auto-inc after mysqld restart
- Init AUTOINC from delete_row().
Bug #28781: InnoDB increments auto-increment value incorrectly with ON DUPLICATE KEY UPDATE
- Use value specified by MySQL, in update_row().
