MAP 'REPAIR TABLE' TO RECREATE +ANALYZE FOR ENGINES NOT
SUPPORTING NATIVE REPAIR
Executing 'mysqlcheck --check-upgrade --auto-repair ...' will first issue
'CHECK TABLE FOR UPGRADE' for all tables in the database in order to check if the
tables are compatible with the current version of MySQL. Any tables that are
found incompatible are then upgraded using 'REPAIR TABLE'.
The problem was that some engines (e.g. InnoDB) do not support 'REPAIR TABLE'.
This caused any such tables to be left incompatible. As a result such tables were
not properly fixed by the mysql_upgrade tool.
This patch fixes the problem by first changing 'CHECK TABLE FOR UPGRADE' to return
a different error message if the engine does not support REPAIR. Instead of
"Table upgrade required. Please do "REPAIR TABLE ..." it will report
"Table rebuild required. Please do "ALTER TABLE ... FORCE ..."
Second, the patch changes mysqlcheck to do 'ALTER TABLE ... FORCE' instead of
'REPAIR TABLE' in these cases.
This patch also fixes 'ALTER TABLE ... FORCE' to actually rebuild the table.
This change should be reflected in the documentation. Before this patch,
'ALTER TABLE ... FORCE' was unused (See Bug#11746162)
Test case added to mysqlcheck.test
client/mysqlcheck.c:
Changed mysqlcheck to do 'ALTER TABLE ... FORCE' if
'CHECK TABLE FOR UPGRADE' reports ER_TABLE_NEEDS_REBUILD
and not ER_TABLE_NEEDS_UPGRADE.

UPDATES THE TABLE ENTRIES (formerly 55385)
BUG#11764529: MULTI UPDATE+INNODB REPORTS ER_KEY_NOT_FOUND
IF A TABLE IS UPDATED TWICE (formerly 57373)
If multiple-table update updates a row through two aliases and
the first update physically moves the row, the second update will
fail to locate the row. This results in different errors
depending on storage engine:
* MyISAM: Got error 134 from storage engine
* InnoDB: Can't find record in 'tbl'
None of these errors accurately describe the problem.
Furthermore, since MyISAM is non-transactional, the update
executed first will be performed while the second will not.
In addition, for two equal multiple-table update statements,
one could succeed and the other fail based on whether or not
the record actually moved or not. This was inconsistent.
Two update operations may physically move a row:
1) Update of a column in a clustered primary key
2) Update of a column used to calculate which partition the
row belongs to
BUG#11764529 is about case 1) above, BUG#11762751 was about case 2).
The fix for these bugs is to return with an error if multiple-table
update is about to:
a) Update a table through multiple aliases, and
b) Perform an update that may physically more the row
in at least one of these aliases
This avoids
* partial updates as described for MyISAM above,
* provides the same error message that describes the actual problem
for all SEs
* inconsistent behavior where a statement fails or succeeds based on
e.g. the partitioning algorithm of the table.

The autotools-based build system has been superseded and
is being removed in order to ease the maintenance burden on
developers tweaking and maintaining the build system.
In order to support tools that need to extract the server
version, a new file that (only) contains the server version,
called VERSION, is introduced. The file contents are human
and machine-readable. The format is:
MYSQL_VERSION_MAJOR=5
MYSQL_VERSION_MINOR=5
MYSQL_VERSION_PATCH=8
MYSQL_VERSION_EXTRA=-rc
The CMake based version extraction in cmake/mysql_version.cmake
is changed to extract the version from this file. The configure
to CMake wrapper is retained for backwards compatibility and to
support the BUILD/ scripts. Also, a new a makefile target
show-dist-name that prints the server version is introduced.
VERSION:
Add top-level version file.
cmake/mysql_version.cmake:
Get version information from the top-level VERSION file.
Do not cache the version components (MAJOR_VERSION, etc).
Add MYSQL_RPM_VERSION as a replacement for MYSQL_U_SCORE_VERSION.
After the WL#2687, the binlog_cache_size and max_binlog_cache_size affect both the
stmt-cache and the trx-cache. This means that the resource used is twice the amount
expected/defined by the user.
The binlog_cache_use is incremented when the stmt-cache or the trx-cache is used
and binlog_cache_disk_use is incremented when the disk space from the stmt-cache or the
trx-cache is used. This behavior does not allow to distinguish which cache may be harming
performance due to the extra disk accesses and needs to have its in-memory cache
increased.
To fix the problem, we introduced two new options and status variables related to the
stmt-cache:
Options:
. binlog_stmt_cache_size
. max_binlog_stmt_cache_size
Status Variables:
. binlog_stmt_cache_use
. binlog_stmt_cache_disk_use
So there are
. binlog_cache_size that defines the size of the transactional cache for
updates to transactional engines for the binary log.
. binlog_stmt_cache_size that defines the size of the statement cache for
updates to non-transactional engines for the binary log.
. max_binlog_cache_size that sets the total size of the transactional
cache.
. max_binlog_stmt_cache_size that sets the total size of the statement
cache.
. binlog_cache_use that identifies the number of transactions that used the
temporary transactional binary log cache.
. binlog_cache_disk_use that identifies the number of transactions that used
the temporary transactional binary log cache but that exceeded the value of
binlog_cache_size.
. binlog_stmt_cache_use that identifies the number of statements that used the
temporary non-transactional binary log cache.
. binlog_stmt_cache_disk_use that identifies the number of statements that used
the temporary non-transactional binary log cache but that exceeded the value of
binlog_stmt_cache_size.

Merge 5.3-mwl89 into 5.3 main.
There is one remaining test failure in this merge:
innodb_mysql_lock2. All other tests have been checked to
deliver the same results/explains as 5.3-mwl89, including
the few remaining wrong results.
The error message for ER_SLAVE_HEARTBEAT_VALUE_OUT_OF_RANGE was
hard coded. Additionally, the same error was used in three
separate error symptoms: 1. when heartbeat period exceeds the
value of slave_net_timeout, 2. when it is smaller than 1
milisecond and 3. when it was not in range, ie, either negative
or greater than the maximum allowed.
We fix this by splitting into three distinct errors and by
removing the message from the source code and moving it to the
errmsg-utf8.txt file.
Bug#54678: InnoDB, TRUNCATE, ALTER, I_S SELECT, crash or deadlock
- Incompatible change: truncate no longer resorts to a row by
row delete if the storage engine does not support the truncate
method. Consequently, the count of affected rows does not, in
any case, reflect the actual number of rows.
- Incompatible change: it is no longer possible to truncate a
table that participates as a parent in a foreign key constraint,
unless it is a self-referencing constraint (both parent and child
are in the same table). To work around this incompatible change
and still be able to truncate such tables, disable foreign checks
with SET foreign_key_checks=0 before truncate. Alternatively, if
foreign key checks are necessary, please use a DELETE statement
without a WHERE condition.
Problem description:
The problem was that for storage engines that do not support
truncate table via a external drop and recreate, such as InnoDB
which implements truncate via a internal drop and recreate, the
delete_all_rows method could be invoked with a shared metadata
lock, causing problems if the engine needed exclusive access
to some internal metadata. This problem originated with the
fact that there is no truncate specific handler method, which
ended up leading to a abuse of the delete_all_rows method that
is primarily used for delete operations without a condition.
Solution:
The solution is to introduce a truncate handler method that is
invoked when the engine does not support truncation via a table
drop and recreate. This method is invoked under a exclusive
metadata lock, so that there is only a single instance of the
table when the method is invoked.
Also, the method is not invoked and a error is thrown if
the table is a parent in a non-self-referencing foreign key
relationship. This was necessary to avoid inconsistency as
some integrity checks are bypassed. This is inline with the
fact that truncate is primarily a DDL operation that was
designed to quickly remove all data from a table.
mysql-test/suite/innodb/t/innodb-truncate.test:
Add test cases for truncate and foreign key checks.
Also test that InnoDB resets auto-increment on truncate.
mysql-test/suite/innodb/t/innodb.test:
FK is not necessary, test is related to auto-increment.
Update error number, truncate is no longer invoked if
table is parent in a FK relationship.
mysql-test/suite/innodb/t/innodb_mysql.test:
Update error number, truncate is no longer invoked if
table is parent in a FK relationship.
Use delete instead of truncate, test is used to check
the interaction of FKs, triggers and delete.
mysql-test/suite/parts/inc/partition_check.inc:
Fix typo.
mysql-test/suite/sys_vars/t/foreign_key_checks_func.test:
Update error number, truncate is no longer invoked if
table is parent in a FK relationship.
mysql-test/t/mdl_sync.test:
Modify test case to reflect and ensure that truncate takes
a exclusive metadata lock.
mysql-test/t/trigger-trans.test:
Update error number, truncate is no longer invoked if
table is parent in a FK relationship.
sql/ha_partition.cc:
Reorganize the various truncate methods. delete_all_rows is now
passed directly to the underlying engines, so as truncate. The
code responsible for truncating individual partitions is moved
to ha_partition::truncate_partition, which is invoked when a
ALTER TABLE t1 TRUNCATE PARTITION p statement is executed.
Since the partition truncate no longer can be invoked via
delete, the bitmap operations are not necessary anymore. The
explicit reset of the auto-increment value is also removed
as the underlying engines are now responsible for reseting
the value.
sql/handler.cc:
Wire up the handler truncate method.
sql/handler.h:
Introduce and document the truncate handler method. It assumes
certain use cases of delete_all_rows.
Add method to retrieve the list of foreign keys referencing a
table. Method is used to avoid truncating tables that are
parent in a foreign key relationship.
sql/share/errmsg-utf8.txt:
Add error message for truncate and FK.
sql/sql_lex.h:
Introduce a flag so that the partition engine can detect when
a partition is being truncated. Used to give a special error.
sql/sql_parse.cc:
Function mysql_truncate_table no longer exists.
sql/sql_partition_admin.cc:
Implement the TRUNCATE PARTITION statement.
sql/sql_truncate.cc:
Change the truncate table implementation to use the new truncate
handler method and to not rely on row-by-row delete anymore.
The truncate handler method is always invoked with a exclusive
metadata lock. Also, it is no longer possible to truncate a
table that is parent in some non-self-referencing foreign key.
storage/archive/ha_archive.cc:
Rename method as the description indicates that in the future
this could be a truncate operation.
storage/blackhole/ha_blackhole.cc:
Implement truncate as no operation for the blackhole engine in
order to remain compatible with older releases.
storage/federated/ha_federated.cc:
Introduce truncate method that invokes delete_all_rows.
This is required to support partition truncate as this
form of truncate does not implement the drop and recreate
protocol.
storage/heap/ha_heap.cc:
Introduce truncate method that invokes delete_all_rows.
This is required to support partition truncate as this
form of truncate does not implement the drop and recreate
protocol.
storage/ibmdb2i/ha_ibmdb2i.cc:
Introduce truncate method that invokes delete_all_rows.
This is required to support partition truncate as this
form of truncate does not implement the drop and recreate
protocol.
storage/innobase/handler/ha_innodb.cc:
Rename delete_all_rows to truncate. InnoDB now does truncate
under a exclusive metadata lock.
Introduce and reorganize methods used to retrieve the list
of foreign keys referenced by a or referencing a table.
storage/myisammrg/ha_myisammrg.cc:
Introduce truncate method that invokes delete_all_rows.
This is required in order to remain compatible with earlier
releases where truncate would resort to a row-by-row delete.
Phase 3: Implementation of re-optimization of subqueries with injected predicates
and cost comparison between Materialization and IN->EXISTS strategies.
The commit contains the following known problems:
- The implementation of EXPLAIN has not been re-engineered to reflect the
changes in subquery optimization. EXPLAIN for subqueries is called during
the execute phase, which results in different code paths during JOIN::optimize
and thus in differing EXPLAIN messages for constant/system tables.
- There are some valgrind warnings that need investigation
- Several EXPLAINs with minor differences need to be reconsidered after fixing
the EXPLAIN problem above.
This patch also adds one extra optimizer_switch: 'in_to_exists' for complete
manual control of the subquery execution strategies.
This patch implements "permanent" load option for
plugins as specified by WL#5341.
mysql-test/r/plugin_load_option.result:
A test case for WL#5341.
mysql-test/t/plugin_load_option-master.opt:
A test case for WL#5341.
mysql-test/t/plugin_load_option.test:
A test case for WL#5341.
sql/share/errmsg-utf8.txt:
An error message for WL#5341.
sql/sql_plugin.cc:
Added FORCE_PLUS_PERMANENT plugin load option.
sql/sql_plugin.h:
Expose and use plugin load option instead of
is_mandatory flag. This is a requirement for
to-be-implemented WL5496.
It was hard to understand what the error really meant.
The error checking in partitioning is done in several different
parts during the execution of a query which can make it
hard to return useful errors.
Added a new error for bad VALUES part in the per PARTITION clause.
Using the more verbose error that a column is not allowed in
the partitioning function instead of just that the function is
not allowed.
mysql-test/r/partition.result:
changed error to be more specific
mysql-test/r/partition_error.result:
updated result
mysql-test/std_data/parts/t1TIMESTAMP.frm:
.frm file of CREATE TABLE t1 (a TIMESTAMP) PARTITION BY HASH(TO_DAYS(a));
mysql-test/t/partition.test:
changed error to be more specific
mysql-test/t/partition_error.test:
Added test (also for verifying behaviour of previously
created tables which is no longer allowed).
Updated expected errors in other places
sql/partition_info.cc:
Added function report_part_expr_error to
be able to return a more specific error.
Renamed fix_func_partition to fix_partition_values
since the function really fixes/checks the VALUES clause.
sql/partition_info.h:
removed part_result_type, since it was unused.
renamed fix_funk_partition->fix_partition_values
added report_part_expr_error
sql/share/errmsg-utf8.txt:
Added a more specific error.
sql/sql_partition.cc:
made use of report_part_expr_error to get a more specific error.
sql/sql_yacc.yy:
Changed error message to be more specific. And return an other error code.
There was no error thrown when creating a table with a virtual table
computed by an expression returning a row.
This caused a crash when inserting into the table.
Removed periods at the end of the error messages for virtual columns.
Adjusted output in test result files accordingly.
