- 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.
A crash may happenin the cases when the range optimizer tried to OR
two index merge such that the second one contained less range trees
than the first one.
The bug was introduced by the patch of MWL#24:
"index_merge: fair choice between index_merge union and range access".
If a primary key was used in the index intersection for
an InnoDB database the size of the memory allocated
for the best index intersection plan was one element less
than it was needed. That could cause a memory overwrite
and a crash as a result of it.

- Flush page cache before closing files (in maria_pack)

Fixed a bug in Unique::unique_add that caused a crash for a query from
index_intersect_innodb on some platforms.
Fixed two bugs in opt_range.cc that led to the choice of not the
cheapest plans for index intersections.
Fixed timing test failures.
Fixed a failure in the Aria engines page cache and log handler (found with maria.maria-big test)
- This could cause a core dump when deleting big blobs.
- Added test to end_pagecache() to verify that page cache was correctly used.
- inc_counter_for_resize_op and dec_counter_for_resize_op are called same number of times.
- All page cache blocks was properly deallocated (empty)

Added missing dec_counter_for_resize_op() to pagecache_delete()
- Make sure creation of t1 is replicated before trying to create trigger on it on slave
- Use safe #ifdef for declaration as for definition to avoid warning about unused static function.

An INSERT query log event is preceeded by an INSERT_ID intvar event if the
INSERT allocates a new auto_increment value. But if we ignore the INSERT
due to --replicate-ignore-table or similar, then the INSERT_ID event is
still executed, and the set value of INSERT_ID lingers around in the
slave sql thread THD object indefinitely until the next INSERT that
happens to need allocation of a new auto_increment value.
Normally this does not cause problems as such following INSERT would
normally come with its own INSERT_ID event. In this bug, the user had
a trigger on the slave which was missing on the master, and this
trigger had an INSERT which could be affected. In any case, it seems
better to not leave a stray INSERT_ID hanging around in the sql thread
THD indefinitely.
Note that events can also be skipped from apply_event_and_update_pos();
however it is not possible in that code to skip the INSERT without also
skipping the INSERT_ID event.

Disable test when run with valgrind as we get errors from buf_buddy_relocate() on work for this test.

Fix MySQL BUG#52344 - Subquery materialization: Assertion if subquery in on-clause of outer join
Original fix and comments from Oysten, adjusted for the different
subquery optimization in MariaDB.
"
Problem: If tables of an outer join are constant tables,
the associated on-clause will be evaluated in the optimization
phase. If the on-clause contains a query that is to be
executed with subquery materialization, this will not work
since the infrastructure for such execution is not yet set up.
Solution: Do not evaluate on-clause in optimization phase if
is_expensive() returns true for this clause. This is how the
problem is currently avoided for where-clauses. This works
because, Item_in_subselect::is_expensive_processor returns true
if query is to be executed with subquery materialization.
"
In addition, after MWL#89, in MariaDB if the IN-EXISTS strategy
is chosen, the in-to-exists predicates are insterted after
join_read_const_table() is called, resulting in evaluation of
the subquery without the in-to-exists predicates.
Open issues:
- A better fix for #57688; Igor is working on this
- Test failure in index_merge_innodb.test ; Igor promised to look at this
- Some Innodb tests fails (need to merge with latest xtradb) ; Kristian promised to look at this.
- Failing tests: innodb_plugin.innodb_bug56143 innodb_plugin.innodb_bug56632 innodb_plugin.innodb_bug56680 innodb_plugin.innodb_bug57255
- Werror is disabled; Should be enabled after merge with xtradb.
Analysis:
The send_data method of the result sink class used to collect
data statistics about materialized subqueries incorrectly assumed
that duplicate rows are removed prior to calling send_data. As
a result the collected statistics was wrong, which resulted in
an incorrect maximal number of keys in the Ordered_key buffer.
Solution:
Try to insert each row into the materialized temp table before
collecting statistics, and if the insertion results in a duplicate
row, do not count the current row.
