* Implemented a second partial matching strategy via table scan.
This strategy is a fallback when there is no memory for rowid merging.
* Refactored the selection and creation of partial matching strategies,
so that the choice of strategy is encapsulated in a separate method
choose_partial_match_strategy().
* Refactored the representation of partial match strategies so that:
- each strategy is represented by a polymorphic class, and
- the base class for all partial match strategies contains common
execution code.
* Added an estimate of the memory needed for the rowid merge strategy,
and the system variable "rowid_merge_buff_size" to control the maximum
memory to be used by the rowid merge algorithm.
* Added two optimizer_switch system variables to control the choice of
partial match strategy:
"partial_match_rowid_merge", "partial_match_table_scan".
* Fixed multiple problems with deallocation of resources by the partial
match strategies.
sql/mysql_priv.h:
* Added two optimizer_switch system variables to control the choice of
partial match strategy:
"partial_match_rowid_merge", "partial_match_table_scan".
sql/mysqld.cc:
* Added two optimizer_switch system variables to control the choice of
partial match strategy:

memory to be used by the rowid merge algorithm.
sql/sql_class.h:
* Added a system variable "rowid_merge_buff_size" to control the maximum
memory to be used by the rowid merge algorithm.
support-files/build-tags:
Newer versions of BZR require the recursive flag in order to list all files.
This patch implements correct NULL semantics for materialized subquery execution.
The implementation has the following properties and main limitations:
- It passes all query result tests, but fails a number of EXPLAIN tests because of
changed plans.
- The EXPLAIN output for partial matching is not decided yet.
- It works only when all necessary indexes fit into main memory. Notice that these
are not the general B-tree/Hash indexes, but instead much more compact ones,
therefore this limitation may not be a problem in many practical cases.
- It doesn't contain specialized tests.
- In several places the implementation uses methods that are modified copies of
other similar methods. These cases need to be refactored to avoid code duplication.
- Add a test if the predicate is top-level just before deciding on partial matching.
If it is top-level, use a more efficient exec method (index lookup).
- Add sorting of indexes according to their selectivity. The code is almost there.
- Needs more comments, and to sync existing ones with the implementation.
sql/item_cmpfunc.h:
Expose the Arg_comparator of a comparison predicate. This makes it possible to
directly get the comparison result {-1,0,1}, which is not possible through the
val_XXX() methods which "fold" such results into a boolean.
sql/item_subselect.cc:
The core of the implementation of MWL#68.
sql/item_subselect.h:
The core of the implementation of MWL#68.
sql/opt_subselect.cc:

for top-level predicates.
sql/sql_class.cc:
New class select_materialize_with_stats that collects data statistics about
the data being inserted into the target table.
sql/sql_class.h:
New class select_materialize_with_stats that collects data statistics about
the data being inserted into the target table.
sql/sql_select.cc:
- more complete initialization of the TABLE object of a temp table.
- call setup_subquery_materialization at one more exit point.
- Make index condition pushdown be controlled by an @@optimizer_switch flag,
not by @@engine_condition_pushdown
- Make MRR buffer size be controlled by @@mrr_buffer_size, not
by @@read_rnd_buffer_size
- Move parts of code to separate files
- Code cleanup
- Add --sorted_result to some SELECTs in tests.
WL#2474 "Multi Range Read: Change the default MRR implementation to implement new MRR interface"
WL#2475 "Batched range read functions for MyISAM/InnoDb"
"Index condition pushdown for MyISAM/InnoDB"
Igor's fix from sp1r-igor@olga.mysql.com-20080330055902-07614:
There could be observed the following problems:
1. EXPLAIN did not mention pushdown conditions from on expressions in the
'extra' column. As a result if a query had no where conditions pushed
down to a table, but had on conditions pushed to this table the 'extra'
column in the EXPLAIN for the table missed 'using where'.
2. Conditions for ref access were not eliminated from on expressions
though such conditions were eliminated from the where condition.
The original code comes, as far as I know, from Google (Mark Callaghan's team) with additional work from Percona, Ourdelta and Weldon Whipple.
This code provides the same functionallity, but with a lot of changes to make it faster and better fit the MariaDB infrastucture.

when used with --tab
1) New syntax: added CHARACTER SET clause to the
SELECT ... INTO OUTFILE (to complement the same clause in
LOAD DATA INFILE).
mysqldump is updated to use this in --tab mode.
2) ESCAPED BY/ENCLOSED BY field parameters are documented as
accepting CHAR argument, however SELECT .. INTO OUTFILE
silently ignored rests of multisymbol arguments.
For the symmetrical behavior with LOAD DATA INFILE the
server has been modified to fail with the same error:
ERROR 42000: Field separator argument is not what is
expected; check the manual
3) Current LOAD DATA INFILE recognizes field/line separators
"as is" without converting from client charset to data
file charset. So, it is supposed, that input file of
LOAD DATA INFILE consists of data in one charset and
separators in other charset. For the compatibility with
that [buggy] behaviour SELECT INTO OUTFILE implementation
has been saved "as is" too, but the new warning message
has been added:
Non-ASCII separator arguments are not fully supported
This message warns on field/line separators that contain
non-ASCII symbols.
client/mysqldump.c:
mysqldump has been updated to call SELECT ... INTO OUTFILE
statement with a charset from the --default-charset command
line parameter.

sql/field.cc:
String conversion code has been moved from check_string_copy_error()
to convert_to_printable() for reuse.
sql/share/errmsg.txt:
New WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED message has been added.
sql/sql_class.cc:
The select_export::prepare() method has been modified to:
1) raise the ER_WRONG_FIELD_TERMINATORS error on multisymbol
ENCLOSED BY/ESCAPED BY field arguments like LOAD DATA INFILE;
2) warn with a new WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED
message on non-ASCII field or line separators.
The select_export::send_data() merhod has been modified to
convert item data to output charset (see new SELECT INTO OUTFILE
syntax). By default the BINARY charset is used for backward
compatibility.
sql/sql_class.h:
The select_export::write_cs field added to keep output
charset.
sql/sql_load.cc:
mysql_load has been modified to warn on non-ASCII field or
line separators with a new WARN_NON_ASCII_SEPARATOR_NOT_IMPLEMENTED
message.
sql/sql_string.cc:
New global function has been added: convert_to_printable()
(common code has been moved from check_string_copy_error()).
sql/sql_string.h:
New String::is_ascii() method and new global convert_to_printable()
function have been added.
sql/sql_yacc.yy:
New syntax: added CHARACTER SET clause to the
SELECT ... INTO OUTFILE (to complement the same clause in
LOAD DATA INFILE). By default the BINARY charset is used for
backward compatibility.

sql/sql_connect.cc:
Check only if a thread was actually created.
The problem is that when a optimization of read-only transactions
(bypass 2-phase commit) was implemented, it removed the code that
reseted the XID once a transaction wasn't active anymore:
sql/sql_parse.cc:
- bzero(&thd->transaction.stmt, sizeof(thd->transaction.stmt));
- if (!thd->active_transaction())
- thd->transaction.xid_state.xid.null();
+ thd->transaction.stmt.reset();
This mostly worked fine as the transaction commit and rollback
functions (in handler.cc) reset the XID once the transaction is
ended. But those functions wouldn't reset the XID in case of
a empty transaction, leading to a assertion when a new starting
a new XA transaction.
The solution is to ensure that the XID state is reset when empty
transactions are ended (by either commit or rollback). This is
achieved by reorganizing the code so that the transaction cleanup
routine is invoked whenever a transaction is ended.
mysql-test/r/xa.result:
Add test case result for Bug#44672
mysql-test/t/xa.test:

Make the caller of Query_log_event, Execute_load_log_event
constructors and THD::binlog_query to provide the error code

MySQL crashes if a user without proper privileges attempts to create a procedure.
The crash happens because more than one error state is pushed onto the Diagnostic
area. In this particular case the user is denied to implicitly create a new user
account with the implicitly granted privileges ALTER- and EXECUTE ROUTINE.
The new account is needed if the original user account contained a host mask.
A user account with a host mask is a distinct user account in this context.
An alternative would be to first get the most permissive user account which
include the current user connection and then assign privileges to that
account. This behavior change is considered out of scope for this bug patch.
The implicit assignment of privileges when a user creates a stored routine is a
considered to be a feature for user convenience and as such it is not
a critical operation. Any failure to complete this operation is thus considered
non-fatal (an error becomes a warning).
The patch back ports a stack implementation of the internal error handler interface.
This enables the use of multiple error handlers so that it is possible to intercept
and cancel errors thrown by lower layers. This is needed as a error handler already
is used in the call stack emitting the errors which needs to be converted.
mysql-test/r/grant.result:
* Added test case for bug44658
mysql-test/t/grant.test:
* Added test case for bug44658
sql/sp.cc:
* Removed non functional parameter no_error and my_error calls as all errors
from this function will be converted to a warning anyway.
* Change function return type from int to bool.
sql/sp.h:
* Removed non functional parameter no_error and my_error calls as all errors
from this function will be converted to a warning anyway.
* Changed function return value from int to bool
sql/sql_acl.cc:

* Introduced an error handler to cancel any error state from mysql_routine_grant.
* Moved my_ok() signal from mysql_routine_grant to make it easier to avoid
setting the wrong state in the Diagnostic area.
* Changed the broken error state in sp_grant_privileges() to a warning
so that if "CREATE PROCEDURE" fails because "Password hash isn't a hexidecimal
number" it is still clear what happened.

setting the wrong state in the Diagnostic area.
due to name_const substitution
Problem:
"In general, statements executed within a stored procedure
are written to the binary log using the same rules that
would apply were the statements to be executed in standalone
fashion. Some special care is taken when logging procedure
statements because statement execution within procedures
is not quite the same as in non-procedure context".
For example, each reference to a local variable in SP's
statements is replaced by NAME_CONST(var_name, var_value).
Queries like
"CREATE TABLE ... SELECT FUNC(local_var ..."
are logged as
"CREATE TABLE ... SELECT FUNC(NAME_CONST("local_var", var_value) ..."
that leads to differrent field names and
might result in "Incorrect column name" if var_value is long enough.
Fix: in 5.x we'll issue a warning in such a case.
In 6.0 we should get rid of NAME_CONST().
Note: this issue and change should be described in the documentation
("Binary Logging of Stored Programs").

Fine-tuning. Broke out comparison into method by
suggestion of Davi. Clarified comments. Reverting
test-case which I find too brittle; proper test
case in 5.1+.
This is a backport of code from MySQL 6.0 with cleanups and extensions
The following new options are supported
configure options:
--with-libevent ; Enable use of libevent, which is needed for pool of threads
mysqld options:
--thread-handling=pool-of-threads ; Use a pool of threads to handle queries
--thread-pool-size=# ; Define how many threads should be created to handle all queries
--extra-port=# ; Extra tcp port that uses the old one-thread-per-connection method
--extra-max-connections=# ; Number of connections to accept to 'extra-port'
--test-ignore-wrong-options ; Ignore setting an enum value to a wrong option (for mysql-test-run)

When binlog_format is STATEMENT and the statement is unsafe before,
the unsafe warning/error message was issued without checking
whether the SQL_LOG_BIN was turned on or not.
Fixed with adding a sql_log_bin_toplevel flag in THD to check
whether SQL_LOG_BIN is ON in current session whatever the current is in sp or not.

There were so many changes into mtr (this is the new mtr coming) that I rather
copied mtr from 6.0-main here (at least this one knows how to run Maria tests).
I also fixed suite/maria tests to be accepted by the new mtr.
mysys/thr_mutex.c:
adding DBUG_PRINT here, so that we can locate where the warning is issued.
