6c173324ff Part of MDEV-10134 Add full support for DEFAULT
Print default values for BLOB's.
This is a part commit for automatic changes to make the real commit smaller.
All changes here are related to that we now print DEFAULT NULL for blob and
text fields, like we do for all other fields.

fb6183a80b MDEV-5244: Make extended_keys=ON by default in 10.0
- Change the default flag value to ON.
- Update the testcases to be run extended_keys=ON:
  = trivial test result updates
  = If extended_keys setting makes a difference for a testcase, run the testcase 
    with extended_keys=off. There were only a few such cases
- Update to vcol_select_innodb looks like a worse plan but it will be gone in 10.0.

e7ad5e36d4 Fix for Bug#14636211 WRONG RESULT (EXTRA ROW) ON A FROM SUBQUERY
WITH A VARIABLE AND ORDER BY
        Bug#16035412 MYSQL SERVER 5.5.29 WRONG SORTING USING COMPLEX INDEX
            
This is a fix for a regression introduced by Bug#12667154:
Bug#12667154 attempted to fix a performance problem with subqueries
that did filesort. For doing filesort, the optimizer creates a quick
select object to use when building the sort index. This quick select
object was deleted after the first call to create_sort_index(). Thus,
for queries where the subquery was executed multiple times, the quick
object was only used for the first execution. For all later executions
of the subquery, filesort used a complete table scan for building the
sort index. The fix for Bug#12667154 tried to fix this by not deleting
the quick object after the first execution of create_sort_index() so
that it would be re-used for building the sort index by the following
executions of the subquery.

This regression introduced in Bug#12667154 is that due to not deleting
the quick select object after building the sort index, the quick
object could in some cases be used also during the second phase of the
execution of the subquery instead of using the created sort
index. This caused wrong results to be returned.

The fix for this issue is to delete the reference to the select object
after it has been used in create_sort_index(). In this way the select 
and quick objects will not be available when doing the second phase
of the execution of the select operation. To ensure that the select
object can be re-used for the following executions of the subquery
we make a copy of the select pointer. This is used for restoring the
select object after the select operation is completed.


mysql-test/suite/innodb/r/innodb_mysql.result:
  Changed explain output: The explain now contains "Using where" since we
  have restored the select pointer after doing the filesort operation.
sql/sql_select.cc:
  Change create_sort_index() so that it always sets the pointer to
  the select object to NULL. This is done in order to avoid that the
  select->quick object can be used when execution the main part of
  the select operation.
sql/sql_select.h:
  New member in JOIN_TAB: saved_select. Used by create_sort_index to
  make a backup copy of the select pointer.

ae5bc05988 Fix for MDEV-533: Confusing error code when doing auto-increment insert for out-of-range values
create table t1 (a smallint primary key auto_increment);
insert into t1 values(32767);
insert into t1 values(NULL);
ERROR 1062 (23000): Duplicate entry '32767' for key 'PRIMARY

Now on always gets error HA_ERR_AUTOINC_RANGE=167 "Out of range value for column", independent of
store engine, SQL Mode or number of inserted rows. This is an unique error that is easier to test for in replication.

Another bug fix is that we now get an error when trying to insert a too big auto-generated value, even in non-strict mode.
Before one get insted the max column value inserted.
This patch also fixes some issues with inserting negative numbers in an auto-increment column.
Fixed the ER_DUP_ENTRY and HA_ERR_AUTOINC_ERANGE are compared the same between master and slave.
This ensures that replication works between an old server to a new slave for auto-increment overflow errors.
Added SQLSTATE errors for handler errors

Smaller bug fixes:
* Added warnings for duplicate key errors when using INSERT IGNORE
* Fixed bug when using --skip-log-bin followed by --log-bin, which did set log-bin to "0"
* Allow one to see how cmake is called by using --just-print --just-configure

4dc963a9f3 Fixed LP bug #999251: Q13 from DBT3 uses table scan instead of covering index scan.
The optimizer chose a less efficient execution plan due to the following
defects of the code:
1. the generic handler function handler::keyread_time did not take into account
   that in clustered primary keys record data is included into each index entry
2. the function make_join_readinfo erroneously decided that index only scan
   could not be used if join cache was empoyed.

Added no additional test case.
Adjusted some of the test results.

Fix for Bug#13430436 PERFORMANCE DEGRADATION IN SYSBENCH ON INNODB DUE TO ICP

When running sysbench on InnoDB there is a performance degradation due
to index condition pushdown (ICP). Several of the queries in sysbench
have a WHERE condition that the optimizer uses for executing these
queries as range scans. The upper and lower limit of the range scan
will ensure that the WHERE condition is fulfilled. Still, the WHERE
condition is part of the queries' condition and if ICP is enabled the
condition will be pushed down to InnoDB as an index condition. 

Due to the range scan's upper and lower limits ensure that the WHERE
condition is fulfilled, the pushed index condition will not filter out
any records. As a result the use of ICP for these queries results in a
performance overhead for sysbench. This overhead comes from using
resources for determining the part of the condition that can be pushed
down to InnoDB and overhead in InnoDB for executing the pushed index
condition.

With the default configuration for sysbench the range scans will use
the primary key. This is a clustered index in InnoDB. Using ICP on a
clustered index provides the lowest performance benefit since the
entire record is part of the clustered index and in InnoDB it has the
highest relative overhead for executing the pushed index condition.

The fix for removing the overhead ICP introduces when running sysbench
is to disable use of ICP when the index used by the query is a
clustered index.

When WL#6061 is implemented this change should be re-evaluated.

072073c09e Backport of WL#5953 from MySQL 5.6
The patch differs from the original MySQL patch as follows:
- All test case differences have been reviewed one by one, and
  care has been taken to restore the original plan so that each
  test case executes the code path it was designed for.
- A bug was found and fixed in MariaDB 5.3 in
  Item_allany_subselect::cleanup().
- ORDER BY is not removed because we are unsure of all effects,
  and it would prevent enabling ORDER BY ... LIMIT subqueries.
- ref_pointer_array.m_size is not adjusted because we don't do
  array bounds checking, and because it looks risky.

Original comment by Jorgen Loland:
-------------------------------------------------------------
WL#5953 - Optimize away useless subquery clauses
      
For IN/ALL/ANY/SOME/EXISTS subqueries, the following clauses are 
meaningless:
      
* ORDER BY (since we don't support LIMIT in these subqueries)
* DISTINCT
* GROUP BY if there is no HAVING clause and no aggregate 
  functions
      
This WL detects and optimizes away these useless parts of the
query during JOIN::prepare()

fecca34356 Fix for bug #11762012 - "54553: INNODB ASSERTS IN
HA_INNOBASE::UPDATE_ROW, TEMPORARY TABLE, TABLE LOCK".

Attempt to update an InnoDB temporary table under LOCK TABLES
led to assertion failure in both debug and production builds
if this temporary table was explicitly locked for READ. The
same scenario works fine for MyISAM temporary tables.

The assertion failure was caused by discrepancy between lock
that was requested on the rows of temporary table at LOCK TABLES
time and by update operation. Since SQL-layer requested a
read-lock at LOCK TABLES time InnoDB engine assumed that upcoming
statements which are going to be executed under LOCK TABLES will
only read table and therefore should acquire only S-lock.
An update operation broken this assumption by requesting X-lock.

Possible approaches to fixing this problem are:

1) Skip locking of temporary tables as locking doesn't make any
   sense for connection-local objects.
2) Prohibit changing of temporary table locked by LOCK TABLES ...
   READ.

Unfortunately both of these approaches have drawbacks which make
them unviable for stable versions of server.

So this patch takes another approach and changes code in such way
that LOCK TABLES for a temporary table will always request write
lock. In 5.5 version of this patch switch from read lock to write
lock is done on SQL-layer.

sql/sql_parse.cc:
  Since a temporary table locked by LOCK TABLES can be updated even
  if it was only locked for read we always request TL_WRITE locks
  for such tables at LOCK TABLES time. This allows to avoid 
  discrepancy between locks acquired at LOCK TABLES time and by
  a statement executed under LOCK TABLES. Such a discrepancy has
  caused problems for InnoDB storage engine.
  
  To support this change a part of code implementing LOCK TABLES 
  has been moved to a helper function.

So this patch takes another approach and changes code in such way
that LOCK TABLES for a temporary table will always request write
lock. In 5.1 version of this patch switch from read lock to write
lock is done inside of InnoDBs handler methods as doing it on 
SQL-layer causes compatibility troubles with FLUSH TABLES WITH
READ LOCK.

8ec03d805d Fixed crashes in the rpl suite due to a bug in Item_func_set_user_var::fix_fields.
Adjusted the result files in  the pbxt, innodb and innodb_plugin suites.

Commented out a failing test case in innodb.innodb_multi_update.test.
It should be returned back when the problem with multi-update of derived
tables (bug 784297) is resolved.

704f97035f Merged the code of MWL#106 into 5.3
Resolved all conflicts, bad merges and fixed a few minor bugs in the code.
Commented out the queries from multi_update, view, subselect_sj, func_str,
derived_view, view_grant that failed either with crashes in ps-protocol or
with wrong results.
The failures are clear indications of some bugs in the code and these bugs
are to be fixed.
