shared should provide libmysqlclient.so.18(libmysqlclient_16) too
  don't "use DBD::mysql" explicitly in mytop

don't try to define it for plugins, then, as they don't need it.

Fix by Sergey Petrunia.

This patch only prevents the evaluation of expensive subqueries during optimization.
The crash reported in this bug has been fixed by some other patch.
The fix is to call value->is_null() only when  !value->is_expensive(), because is_null()
may trigger evaluation of the Item, which in turn triggers subquery evaluation if the
Item is a subquery.

In 10.0, VIO timeouts can be in milliseconds, so we add a new function
mysql_get_timeout_value_ms() which can return millisecond-precision
timeout values.

In 5.5, we do not have millisecond precision for timeouts. But we still
provide the mysql_get_timeout_value_ms() function; this makes it easier
for applications as they can use the millisecond function in 10.0 and
still work with the 5.5 version of the client library.

MySQL fix for bug#11765413 removed (we have better and more general fix for the problem).

Test suite added.

cmake/cpack_rpm.cmake:
  * mark all cnf files with %config(noreplace)
  * add the forgotten postun script
sql/sys_vars.cc:
  0 for a string variable means "no default. But datadir has the default value.
support-files/rpm/server-postin.sh:
  * use mysqld --help to determine the correct datadir in the presence of my.cnf files
    (better than my_print_defaults, because it considers the correct group set).
  * Only create users, and chown/chmod if it's a fresh install, not an upgrade.
  * only run mysql_install_db if datadir does not exist

Do not include mytop in mariadb-client-5.5 .deb package.

There is already a Debian mytop package, so we get a package conflict.
And there is no reason for the MariaDB project to guerrilla-take-over
mytop maintenance.

Remove sql directory from the include path to workaround the problem. This removes the ambiguity , since then only one client_settings.h will be in the include paths

Fixed that 'Handler:' output gives correct result with MariaDB (not including temporary tables)

LP bug #1035225 / MySQL bug #66301: INSERT ... ON DUPLICATE KEY UPDATE +
innodb_autoinc_lock_mode=1 is broken

The problem was that when certain INSERT ... ON DUPLICATE KEY UPDATE
were executed concurrently on a table containing an AUTO_INCREMENT
column as a primary key, InnoDB would correctly reserve non-overlapping
AUTO_INCREMENT intervals for each statement, but when the server
encountered the first duplicate key error on the secondary key in one of
the statements and performed an UPDATE, it also updated the internal
AUTO_INCREMENT value to the one from the existing row that caused a
duplicate key error, even though the AUTO_INCREMENT value was not
specified explicitly in the UPDATE clause. It would then proceed with
using AUTO_INCREMENT values the range reserved previously by another
statement, causing duplicate key errors on the AUTO_INCREMENT column.

Fixed by changing write_record() to ensure that in case of a duplicate
key error the internal AUTO_INCREMENT counter is only updated when the
AUTO_INCREMENT value was explicitly updated by the UPDATE
clause. Otherwise it is restored to what it was before the duplicate key
error, as that value is unused and can be reused for subsequent
successfully inserted rows.

sql/sql_insert.cc:
  Don't update next_insert_id to the value of a row found during ON DUPLICATE KEY UPDATE.
sql/sql_parse.cc:
  Added DBUG_SYNC
sql/table.h:
  Added next_number_field_updated flag to detect changing of auto increment fields.
  Moved fields a bit to get bool fields after each other (better alignment)

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

- Performed some refactoring and simplification that was enabled and required by the merge.

Analysis:
The queries in question use the [unique | index]_subquery execution methods.
These methods reuse the ref keys constructed by create_ref_for_key(). The
way create_ref_for_key() works is that it doesn't store in ref.key_copy[]
store_key elements that represent constants. In particular it doesn't store
the store_key for NULL constants.

The execution of [unique | index]_subquery calls
subselect_uniquesubquery_engine::copy_ref_key, which in addition to copy
the left IN argument into a index lookup key, is supposed to detect if
the left IN argument contains NULLs. Since the store_key for the NULL
constant is not copied into the key array, the null is not detected, and
execution erroneously proceeds as if it should look for a complete match.

Solution:
The solution (unlike MySQL) is to reuse already computed information about
NULL presence. Item_in_optimizer::val_int already finds out if the left IN
operand contains NULLs. The fix propagates this to the execution methods
subselect_[unique | index]subquery_engine::exec so it knows if there were
NULL values independent of the presence of keys.

In addition the patch siplifies copy_ref_key() and the logic that hanldes
the case of NULLs in the left IN operand.

As far as we reopen tables so TABLE become invalid we should remove the pointer on cleanup().

The DELETE for emplicitly emptied MEMORY tables should be written directly to binlog.
