b7b25dc666 Merge with 5.1-release.
- Fixed problem with oqgraph and 'make dist'

Note that after this merge we have a problem show in join_outer where we examine too many rows in one specific case (related to BUG#57024).
This will be fixed when mwl#128 is merged into 5.3.

2737a72278 Bug#58147: ALTER TABLE w/ TRUNCATE PARTITION fails
but the statement is written to binlog

TRUNCATE PARTITION was written to the binlog
even if it failed before calling any partition's
truncate function.

Solved by adding an argument to truncate_partition,
to flag if it should be written to the binlog or not.

It should be written to the binlog when a call to any
partitions truncate function is done.

mysql-test/r/partition_binlog.result:
  New result file
mysql-test/t/partition_binlog.test:
  New test file, including DROP PARTITION binlog test
sql/ha_partition.cc:
  Added argument to avoid binlogging failed truncate_partition that

  Added argument to avoid excessive binlogging
sql/sql_partition_admin.cc:
  Avoid to binlog TRUNCATE PARTITION if it fails before
  any partition has tried to truncate.

e0a8c25438 Bug#57890: Assertion failed: next_insert_id == 0
with on duplicate key update

There was a missed corner case in the partitioning
handler, which caused the next_insert_id to be changed
in the second level handlers (i.e the hander of a partition),
which caused this debug assertion.

The solution was to always ensure that only the partitioning
level generates auto_increment values, since if it was done
within a partition, it may fail to match the partition
function.

mysql-test/suite/parts/inc/partition_auto_increment.inc:
  Added tests

  updated results

mysql-test/suite/parts/r/partition_auto_increment_memory.result:
  updated results
mysql-test/suite/parts/r/partition_auto_increment_myisam.result:
  updated results
sql/ha_partition.cc:
  In <engine>::write_row the auto_inc value is generated
  through handler::update_auto_increment (which calls <engine>::get_auto_increment() if needed).
  If:
  * INSERT_ID was set to 0
  * it was updated to 0 by 'INSERT ... ON DUPLICATE KEY UPDATE' and changed partitions for the row
  Then it would try to generate a auto_increment value in the
  <engine for a specific partition>::write_row, which will
  trigger the assert.
  
  So the solution is to prevent this by,
  in ha_partition::write_row set auto_inc_field_not_null and
  add MODE_NO_AUTO_VALUE_ON_ZERO
  in ha_partition::update_row (when changing partition) temporary
  set table->next_number_field to NULL which calling the
  partitions ::write_row().

c04318ed24 Bug#57778: failed primary key add to partitioned innodb table inconsistent and crashes
It was possible to issue an ALTER TABLE ADD PRIMARY KEY on
an partitioned InnoDB table that failed and crashed the server.

The problem was that it succeeded to create the PK on at least
one partition, and then failed on a subsequent partition, due to
duplicate key violation. Since the partitions that already had added
the PK was not reverted all partitions was not consistent with the
table definition, which caused the crash.

The solution was to add a revert step to ha_partition::add_index()
that dropped the index for the already succeeded partitions, on failure.

mysql-test/r/partition.result:
  updated result
mysql-test/t/partition.test:
  Added test
sql/ha_partition.cc:
  Only allow ADD/DROP flags in pairs, so that they can be reverted on failures.
  If add_index() fails for a partition, revert (drop the index) for the previous
  partitions.
sql/handler.h:
  Added some extra info in a comment.

a5efb91dea Bug#49938: Failing assertion: inode or deadlock in fsp/fsp0fsp.c
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.

814fbc5b6f Bug#51851: Server with SBR locks mutex twice on
LOAD DATA into partitioned MyISAM table

Problem was that both partitioning and myisam
used the same table_share->mutex for different protections
(auto inc and repair).

Solved by adding a specific mutex for the partitioning
auto_increment.

Also adding destroying the ha_data structure in
free_table_share (which is to be propagated
into 5.5).

This is a 5.1 ONLY patch, already fixed in 5.5+.

428f0bdefb Bug#56287: mysql5.1.50 crash when using Partition datetime in sub in query
When having a sub query in partitioned innodb one could
make the partitioning engine to search for a 'index_next_same'
on a partition that had not been initialized.

Problem was that the subselect function looks at table->status
which was not set in the partitioning handler when it skipped
scanning due to no matching partitions found.

Fixed by setting table->status = STATUS_NOT_FOUND when
there was no partitions to scan. (If there are partitions to
scan, it will be set in the partitions handler.)

6d14cae604 Bug#55146 Assertion `m_part_spec.start_part == m_part_spec.end_part' in index_read_idx_map
As we check for the impossible partitions earlier, it's possible that we don't find any
              suitable partitions at all. So this assertion just has to be corrected for this case.
      
per-file comments:

Bug#55146      Assertion `m_part_spec.start_part == m_part_spec.end_part' in index_read_idx_map
        test result updated.

Bug#55146      Assertion `m_part_spec.start_part == m_part_spec.end_part' in index_read_idx_map
        test case added.

sql/ha_partition.cc
Bug#55146      Assertion `m_part_spec.start_part == m_part_spec.end_part' in index_read_idx_map
        Assertion changed to '>=' as the  prune_partition_set() in the get_partition_set() can
        do start_part= end_part+1 if no possible partitions were found.

b409fad8cc Bug#55458: Partitioned MyISAM table gets crashed by multi-table update
Problem was that the handler call ::extra(HA_EXTRA_CACHE) was cached
but the ::extra(HA_EXTRA_PREPARE_FOR_UPDATE) was not.

Solution was to also cache the other call and forward it when moving
to a new partition to scan.

mysql-test/r/partition.result:
  test result
mysql-test/t/partition.test:
  New test from bug report.
sql/ha_partition.cc:
  cache the HA_EXTRA_PREPARE_FOR_UPDATE just like HA_EXTRA_CACHE.
sql/ha_partition.h:
  Added cache flag for HA_EXTRA_PREPARE_FOR_UPDATE

e9166ca152 Fix for LP#588251: doStartTableScan() result not checked.
The issue was that we didn't always check result of ha_rnd_init() which caused a problem for handlers that returned an error in this code.
- Changed prototype of ha_rnd_init() to ensure that we get a compile warning if result is not checked.
- Added ha_rnd_init_with_error() that prints error on failure.
- Checked all usage of ha_rnd_init() and ensure we generate an error message on failures.
- Changed init_read_record() to return 1 on failure.

ecbcddc03d Improved speed of thr_alarm from O(N) to O(1). thr_alarm is used to handle timeouts and kill of connections.
Fixed compiler warnings.
queues.h and queues.c are now based on the UNIREG code and thus made BSD.
Fix code to use new queue() interface. This mostly affects how you access elements in the queue.
If USE_NET_CLEAR is not set, don't clear connection from unexpected characters. This should give a speed up when doing a lot of fast queries.
Fixed some code in ma_ft_boolean_search.c that had not made it from myisam/ft_boolean_search.c


include/queues.h:
  Use UNIREG code base (BSD)
  Changed init_queue() to take all initialization arguments.
  New interface to access elements in queue
include/thr_alarm.h:
  Changed to use time_t instead of ulong (portability)
  Added index_in_queue, to be able to remove random element from queue in O(1)
mysys/queues.c:
  Use UNIREG code base (BSD)
  init_queue() and reinit_queue() now takes more initialization arguments. (No need for init_queue_ex() anymore)
  Now one can tell queue_insert() to store in the element a pointer to where element is in queue. This allows one to remove elements from queue in O(1) instead of O(N)
mysys/thr_alarm.c:
  Use new option in queue() to allow fast removal of elements.
  Do less inside LOCK_alarm mutex.
  This should give a major speed up of thr_alarm usage when there is many threads
sql/create_options.cc:
  Fixed wrong printf
sql/event_queue.cc:
  Use new queue interface()
sql/filesort.cc:
  Use new queue interface()
sql/ha_partition.cc:
  Use new queue interface()
sql/ha_partition.h:
  Fixed compiler warning
sql/item_cmpfunc.cc:
  Fixed compiler warning
sql/item_subselect.cc:
  Use new queue interface()
  Removed not used variable
sql/net_serv.cc:
  If USE_NET_CLEAR is not set, don't clear connection from unexpected characters.
  This should give a speed up when doing a lot of fast queries at the disadvantage that if there is a bug in the client protocol the connection will be dropped instead of being unnoticed.
sql/opt_range.cc:
  Use new queue interface()
  Fixed compiler warnings
sql/uniques.cc:
  Use new queue interface()
storage/maria/ma_ft_boolean_search.c:
  Copy code from myisam/ft_boolean_search.c
  Use new queue interface()
storage/maria/ma_ft_nlq_search.c:
  Use new queue interface()
storage/maria/ma_sort.c:
  Use new queue interface()
storage/maria/maria_pack.c:
  Use new queue interface()
  Use queue_fix() instead of own loop to fix queue.
storage/myisam/ft_boolean_search.c:
  Use new queue interface()
storage/myisam/ft_nlq_search.c:
  Use new queue interface()
storage/myisam/mi_test_all.sh:
  Remove temporary file from last run
storage/myisam/myisampack.c:
  Use new queue interface()
  Use queue_fix() instead of own loop to fix queue.
storage/myisam/sort.c:
  Use new queue interface()
storage/myisammrg/myrg_queue.c:
  Use new queue interface()
storage/myisammrg/myrg_rnext.c:
  Use new queue interface()
storage/myisammrg/myrg_rnext_same.c:
  Use new queue interface()
storage/myisammrg/myrg_rprev.c:
  Use new queue interface()
