This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Allocation of memory for the sort buffer at each evaluation of a
subquery may take a significant amount of time if the buffer is rather big.
With the fix we allocate the buffer at the first evaluation of the
subquery and reuse it at each subsequent evaluation.

list using a function
When executing dependent subqueries they are re-inited and re-exec() for
each row of the outer context.
The cause for the bug is that during subquery reinitialization/re-execution,
the optimizer reallocates JOIN::join_tab, JOIN::table in make_simple_join()
and the local variable in 'sortorder' in create_sort_index(), which is
allocated by make_unireg_sortorder().
Care must be taken not to allocate anything into the thread's memory pool
while re-initializing query plan structures between subquery re-executions.
All such items mush be cached and reused because the thread's memory pool
is freed at the end of the whole query.
Note that they must be cached and reused even for queries that are not
otherwise cacheable because otherwise it will grow the thread's memory
pool every time a cacheable query is re-executed.
We provide additional members to the JOIN structure to store references
to the items that need to be cached.

Bug #21785 "Server crashes after rename of the log table" and
Bug #21966 "Strange warnings on create like/repair of the log
tables"
According to the patch, from now on, one should use RENAME to
perform a log table rotation (this should also be reflected in
the manual).
Here is a sample:
use mysql;
CREATE TABLE IF NOT EXISTS general_log2 LIKE general_log;
RENAME TABLE general_log TO general_log_backup, general_log2 TO general_log;
The rules for Rename of the log tables are following:
IF 1. Log tables are enabled
AND 2. Rename operates on the log table and nothing is being
renamed to the log table.
DO 3. Throw an error message.
ELSE 4. Perform rename.
The very RENAME query will go the the old (backup) table. This is
consistent with the behavoiur we have with binlog ROTATE LOGS
statement.
Other problems, which are solved by the patch are:
1) Now REPAIR of the log table is exclusive operation (as it should be), this
also eliminates lock-related warnings. and
2) CREATE LIKE TABLE now usese usual read lock on the source table rather
then name lock, which is too restrictive. This way we get rid of another
log table-related warning, which occured because of the above fact
(as a side-effect, name lock resulted in a warning).
mysql-test/r/log_tables.result:

1) Add checks for table schema. It's more important now,
as we allow rename of the log tables. Since we should
check for schema when writing to a log table.
E.g. if one created a table with one-only comlumn and
renamed it to general_log, the server should cope with
it.
2) refactor LOGGER::flush(), so that we can now use the same
machinery as we use in FLUSH LOGS in other statements:
whenever we have to perform a serious operation on the log
tables, we have to
(a) lock logger, which blocks other concurrent statements (such
as selects) (b) close logs. Then perform an
exclusive operation, c) reenable logs and d) unlock logger.
3) Add a function to check if a given table is a log table.
4) Add support for "privileged" thread
5) merge is_[general/slow]_log_table_enabled() into one function.
6) Add new function: reopen _log_tables, which reopens the tables,
which were enabled (after temporary close, required for admin
operation)
sql/log.h:
1) add a new call close_n_lock_tables(). Now we use it instead of
LOGGER::flush() in FLUSH LOGS implementation.
2) add a prototype for the function to check if a given
table is a log table;
3) add privileged table flag to table logger
4) merge is_[general/slow]_log_table_enabled()
into one function.
sql/mysql_priv.h:
move log table defines to log.h
sql/sql_delete.cc:
use new function check_if_log_table() instead of direct strcmp
sql/sql_rename.cc:
Traverse the list of tables in mysql_rename_tables
to make sure that log tables are processed correctly
(that is, according to the rules specified in the
main CS comment)
sql/sql_table.cc:
1) mysql_admin_table() should disable logs if it performs
exclusive admin operation on a log table. This way we
also eliminate warning on REPAIR of the log table.
2) mysql_create_like_table should read-lock the source table
instead getting name lock on it. Name lock is too restrictive
in this case.
sql/share/errmsg.txt:
Add a new error message for rename of the log tables
sql/table.cc:
use new function instead of direct strcmp.
change my_strcasecmp() -> strcmp(), when
comparing system db and table names
storage/csv/ha_tina.cc:
update function to reflect changes in log tables
locking logic.
storage/myisam/ha_myisam.cc:
update function to reflect changes in log tables
locking logic.

(race cond)
It was possible for one thread to interrupt a Data Definition Language
statement and thereby get messages to the binlog out of order. Consider:
Connection 1: Drop Foo x
Connection 2: Create or replace Foo x
Connection 2: Log "Create or replace Foo x"
Connection 1: Log "Drop Foo x"
Local end would have Foo x, but the replicated slaves would not.
The fix for this is to wrap all DDL and logging of a kind in the same mutex.
Since we already use mutexes for the various parts of altering the server,
this only entails moving the logging events down close to the action, inside
the mutex protection.

sql/sp.cc:
Move logging inside the routine drop and update functions, so it can be
protected by a LOCK_open mutex. (The "create" function already had such
a LOCK_open protection.)
sql/sql_acl.cc:
Move logging inside the grant functions, so that it can be protected by
LOCK_grant .
sql/sql_db.cc:
Add comments that describe how each logging event is protected.
sql/sql_parse.cc:
Move all logging statements about DDL statements close to the actual event,
so each can be protected by the same mutex.

The problem was that during DROP TEMPORARY TABLE we tried to acquire
the name lock, though temporary tables belongs to one connection, and
no race is possible.
The solution is to not use table name locking while executing
DROP TEMPORARY TABLE.

gets deadlocked when dropping w/ log on"
Log tables rely on concurrent insert machinery to add data.
This means that log tables are always opened and locked by
special (artificial) logger threads. Because of this, the thread
which tries to drop a log table starts to wait for the table
to be unlocked. Which will happen only if the log table is disabled.
Alike situation happens if one tries to alter a log table.
However in addition to the problem above, alter table calls
check_if_locking_is_allowed() routine for the engine. The
routine does not allow alter for the log tables. So, alter
doesn't start waiting forever for logs to be disabled, but
returns with an error.
Another problem is that not all engines could be used for
the log tables. That's because they need concurrent insert.
In this patch we:
(1) Explicitly disallow to drop/alter a log table if it
is currently used by the logger.
(2) Update MyISAM to support log tables
(3) Allow to drop log tables/alter log tables if log is
disabled
At the same time we (4) Disallow to alter log tables to
unsupported engine (after this patch CSV and MyISAM are
alowed)
Recommit with review fixes.
mysql-test/r/log_tables.result:
Update result file.
Note: there are warnings in result file. This is because of CSV
bug (Bug #21328). They should go away after it is fixed.
mysql-test/t/log_tables.test:
Add a test for the bug
sql/ha_myisam.cc:
Add log table handling to myisam: as log tables
use concurrent insert, they are typically
locked with TL_CONCURRERENT_INSERT lock. So,
disallow other threads to attempt locking of
the log tables in incompatible modes. Because
otherwise the threads will wait for the tables
to be unlocked forever.
sql/handler.cc:
Add a function to check if a table we're going to lock
is a log table and if the lock mode we want allowed
sql/handler.h:
Add a new function to check compatibility of the locking
sql/log.cc:
we shouldn't close the log table if and only
if this particular table is already closed
sql/log.h:
add new functions to check if a log is enabled
sql/share/errmsg.txt:
add new error messages
sql/sql_table.cc:
DROP and ALTER TABLE should not work on log
tables if the log tables are enabled
storage/csv/ha_tina.cc:
move function to check if the locking for the log
tables allowed to handler class, so that we can
reuse it in other engines.
storage/myisam/mi_extra.c:
add new ::extra() flag processing to myisam
storage/myisam/mi_open.c:
init log table flag
storage/myisam/mi_write.c:
update status after each write if it's a log table
storage/myisam/myisamdef.h:
Add new log table flag to myisam share.
We need it to distinguish between usual
and log tables, as for the log tables we
should provide concurrent insert in a
different way than for usual tables: we
want new rows to be immediately visible
to other threads.
