In some functions dealing with strings and character sets, the wrong
pointers were saved for restoration in THD::rollback_item_tree_changes().
This could potentially cause random corruption or crashes.
Fixed by passing the original Item ** locations, not local stack copies.
Also remove unnecessary use of default arguments.
sql/item.cc:
Function agg_item_charsets() now handles non-consequtive Item *'s.
sql/item.h:
Remove use of default argument.
sql/item_cmpfunc.cc:
Remove use of default argument.
sql/item_func.cc:
Remove use of default argument.
sql/item_func.h:
Function agg_item_charsets() now handles non-consequtive Item *'s.
sql/item_strfunc.cc:
Pass original Item **'s to agg_arg_charsets(), not local copies, to ensure
proper restoration in THD::rollback_item_tree_changes().
sql/item_sum.cc:
Remove use of default argument.
- Added comments.
- Make SEL_ARG::clone() set SEL_ARG::elements in the created copy.

It was hard to distinguish case, when one was unable to create trigger
on the table because trigger with same action time and event already
existed for this table, from the case, when one tried to create trigger
with name which was already occupied by some other trigger, since in
both these cases we emitted ER_TRG_ALREADY_EXISTS error and message.
Now we emit ER_NOT_SUPPORTED_YET error with appropriate additional
message in the first case. There is no sense in introducing separate
error for this situation since we plan to get rid of this limitation
eventually.
mysql-test/r/trigger.result:
Update result for new error message.
mysql-test/t/trigger.test:
Update test for new error code.
sql/sql_trigger.cc:
If there is already a trigger with the same activation time, report an
"Unsupported yet" error.
No test case as the bug is in an existing test case (rpl_trigger.test
when it is run under valgrind).
The warning was caused by memory corruption in replication slave: thd->db
was pointing at a stack address that was previously used by
sp_head::execute()::old_db. This happened because mysql_change_db
behaved differently in replication slave and did not make a copy of the
argument to assign to thd->db.
The solution is to always free the old value of thd->db and allocate a new
copy, regardless whether we're running in a replication slave or not.
sql/log_event.cc:
Move rewrite_db to log_event.cc, the only place where it is used.
sql/slave.cc:
Move rewrite_db to log_event.cc
sql/slave.h:
Remove an unneeded declaration.
sql/sql_class.h:
Fix set_db to always free the old db, even if the argument is NULL.
Add a comment.
sql/sql_db.cc:
Always make a deep copy of the argument in mysql_change_db, even
if running in a replication slave. This is necessary because
sp_use_new_db (stored procedures) assumes that mysql_change_db always makes
a deep copy of the argument, and thus passes a pointer to stack into it.
This assumption was true for all cases except the replication slave thread.

Final-review fixes per Monty, pre-push. OK'd for
push. Please see each file's comments.
mysql-test/r/federated.result:
BUG #19773
Results for multi-table deletes, updates
mysql-test/t/federated.test:
BUG #19773
Test multi table update and delete. Added drop table to end of previous test.
sql/ha_federated.cc:
BUG #19773
Post-review changes, per Monty. 3rd patch, OK'd for push.
- Added index_read_idx_with_result_set, which uses the result set passed to it
- Hash by entire connection scheme
- Protected store_result result set for table scan by adding a method result set
to index_read_idx and index_read which is passed to index_read_with_result, which
in turn iterates over the single record via read_next.
This is a change from having two result sets in the first two patches.
This keeps the code clean and avoids the need for yet another result set.
- Rewrote ::position and ::rnd_pos to store position - if primary key use
primary key, if not, use record buffer.
- Rewrote get_share to store hash with connect string vs. table name
- delete_row added subtration of "records" by affected->rows
- Added read_next to handle what rnd_next used to do (converting raw record
to query and vice versa)
- Removed many DBUG_PRINT lines
- Removed memset initialisation since subsequent loop accomplishes
- Removed un-necessary mysql_free_result lines
sql/ha_federated.h:
BUG #19773
Fixed "SET " to " SET " to make sure built statements are built with
"UPDATE `t1` SET .." instead of "UPDATE `t1`SET"
and BUG#19208 "Test 'rpl000017' hangs on Windows".
Both bugs are caused by attempting to delete an opened
file and to create immediatedly a new one with the same
name. On Windows it can be supported only on NT-platforms
(by using FILE_SHARE_DELETE mode and with renaming the
file before deletion). Because deleting not-closed files
is not supported on all platforms (e.g. Win 98|ME) this
is to be considered harmful and should be eliminated by
a "code redesign".
VC++Files/mysys/mysys.vcproj:
To be sure that __NT__ is defined for Win configurations.
Temporary, to be changed in more appropriate way.
include/my_sys.h:
Adding my_delete_allow_opened to be invoked to delete
a (possibly) not closed file on Windows NT-platforms.
mysys/my_delete.c:
Adding nt_share_delete() function implementing
a (possibly) not closed file deletion on Windows NT.

Bug #18361: Triggers on mysql.user table cause server crash
Because they do not work, we do not allow creating triggers on tables
within the 'mysql' schema.

in 5.0 or 5.1.)

The problem was that we restored SQL_CACHE, SQL_NO_CACHE flags in SELECT
statement from internal structures based on value set later at runtime, not
the original value set by the user.
