  authentification fix: one constructor and two
  variables optimised

mysql-test/r/subselect.result:
  correct results
mysql-test/r/union.result:

mysql-test/t/subselect.test:
  to be sure that results are correct
sql/sql_parse.cc:
  comment + TODO

mysql-test/r/subselect.result:
  A warning added to subselect test due to the recent changes.
  
  UNION in sub-select returns the empty set, which is why this warning is
  a mistery to me.
mysql-test/r/union.result:
  two changes.
  
  First one is due to the proper handling of LIMIT offset, limit in 
  UNION without all.
  
  Second is a change in behaviour due to the fact that ORDER by in a 
  UNION without braces is not now applicable to the last SELECT node.
  
  It can not be applied until one bug is fixed (after my vacation).
  
  Should be documented.

DO NOT COPY THIS CODE TO 4.0. The bugfix is better in 4.0,
but here in 3.23 we don't want to add a new error code so
we just use ER_EMPTY_QUERY. Bug was:
"If a query was ignored on the slave (because of
@code{replicate-ignore-table} and other similar rules), the slave
still checked if the query got the same error code (0, no error) as on
the master. So if the master had an error on the query (for example,
``Duplicate entry'' in a multiple-row insert), then the slave stopped
and warned that the error codes didn't match. (Bug #797)"


sql/slave.cc:
  Ignore ER_EMPTY_QUERY as it is also a marker for "query was ignored because 
  of replicate-*-table rules".
sql/sql_parse.cc:
  In a slave thread, mark an ignored query (because of replicate-*-table rules)
  as empty. The caller, exec_event(), will understand this error code as "ignorable
  query, don't compare the error codes on master and slave".

Now LOAD DATA FROM MASTER does not drop the database, instead it only tries to
create it, and drops/creates table-by-table.
* replicate_wild_ignore_table='db1.%' is now considered as "ignore the 'db1'
database as a whole", as it already works for CREATE DATABASE and DROP DATABASE.


mysql-test/r/rpl000009.result:
  result update
mysql-test/t/rpl000009.test:
  test that LOAD DATA FROM MASTER does not drop databases,
  but rather table by table, thus preserving non-replicated tables.
  Test that LOAD DATA FROM MASTER reports the error when a table could not
  be dropped (system's "permission denied" for example).
  Test that LOAD TABLE FROM MASTER reports the error when the table already exists.
sql/repl_failsafe.cc:
  * replicate_wild_ignore_table='db1.%' is now considered as "ignore the 'db1'
  database as a whole", as it already works for CREATE DATABASE and DROP DATABASE.
  * If a db matches replicate_*_db rules, we don't drop/recreate it because this
  could drop some tables in this db which could be slave-specific. Instead,
  we do a CREATE DATABASE IF EXISTS, and we will drop each table which has
  an equivalent on the master, table-by-table.
sql/slave.cc:
  New argument to drop the table in create_table_from_dump() 
  (LOAD TABLE/DATA FROM MASTER are the only places where this function is used).
  This is needed because LOAD DATA FROM MASTER does not drop the database anymore.
  The behaviour when the table exists is unchanged: LOAD DATA silently replaces
  the table, LOAD TABLE gives error.
sql/slave.h:
  new argument to drop the table in fetch_master_table
sql/sql_parse.cc:
  do not drop the table in LOAD TABLE FROM MASTER (this behaviour is already
  true; but changes in LOAD DATA FROM MASTER made the argument needed).

This is to simplify fixing indexes to mean number of chars rather than bytes too.

fix for BUG#1113 "INSERT into non-trans table SELECT ; ROLLBACK" does not send warning"
and
fix for BUG#873 "In transaction, INSERT to non-trans table is written too early to binlog".
Now we don't always write the non-trans update immediately to the binlog;
if there is something in the binlog cache we write it to the binlog cache
(because the non-trans update could depend on a trans table which was modified
earlier in the transaction); then in case of ROLLBACK, we write the binlog
cache to the binlog, wrapped with BEGIN/ROLLBACK.
This guarantees that the slave does the same updates.
For ROLLBACK TO SAVEPOINT: when we execute a SAVEPOINT command we write it
to the binlog cache. At ROLLBACK TO SAVEPOINT, if some non-trans table was updated,
we write ROLLBACK TO SAVEPOINT to the binlog cache; when the transaction
terminates (COMMIT/ROLLBACK), the binlog cache will be flushed to the binlog
(because of the non-trans update) so we'll have SAVEPOINT and ROLLBACK TO
SAVEPOINT in the binlog.

Apart from this rare case of updates of mixed table types in transaction, the
usual way is still clear the binlog cache at ROLLBACK, or chop it at
ROLLBACK TO SAVEPOINT (meaning the SAVEPOINT command is also chopped, which
is fine).
Note that BUG#873 encompasses subbugs 1) and 2) of BUG#333 "3 binlogging bugs when doing INSERT with mixed InnoDB/MyISAM".


client/mysqldump.c:
  Minor edit: one CHANGE MASTER with 2 arguments instead of 2 CHANGE MASTER with one argument each.
mysql-test/r/rpl_loaddata.result:
  result update
mysql-test/t/rpl_loaddata.test:
  minor edit: simplifying the test.
sql/handler.cc:
  Fix for BUG#873. See comments in code, and the description of the changeset.
sql/log.cc:
  * Previously, if a query updated a non-transactional table we wrote it immediately
  to the real binlog. This causes a bug when the update is done inside a transaction
  and uses the content of an updated transactional table (because this makes
  a wrong order of queries in the binlog). So if the binlog cache is not empty,
  we write the query to the binlog cache; otherwise we can write it to the binlog.
  * Previously, when we flushed the binlog cache to the binlog, we wrapped it
  with BEGIN/COMMIT. Now it's also possible to wrap it with BEGIN/ROLLBACK, to handle
  transactions which update both transactional and non-transactional tables.
sql/log_event.cc:
  The slave thread can leave a transaction if COMMIT or if ROLLBACK.
sql/sql_class.h:
  prototype
sql/sql_insert.cc:
  Fix for BUG#1113:
  this was because the INSERT SELECT code did not set OPTION_STATUS_NO_TRANS_UPDATE.
sql/sql_parse.cc:
  Don't send ER_WARNING_NOT_COMPLETE_ROLLBACK if this is the SQL slave thread (see comments).
