Note: bug#21726 does not directly apply to 4.1, as it doesn't have stored
procedures. However, 4.1 had some bugs that were fixed in 5.0 by the
patch for bug#21726, and this patch is a backport of those fixes.
Namely, in 4.1 it fixes:
- LAST_INSERT_ID(expr) didn't return value of expr (4.1 specific).
- LAST_INSERT_ID() could return the value generated by current
statement if the call happens after the generation, like in
CREATE TABLE t1 (i INT AUTO_INCREMENT PRIMARY KEY, j INT);
INSERT INTO t1 VALUES (NULL, 0), (NULL, LAST_INSERT_ID());
- Redundant binary log LAST_INSERT_ID_EVENTs could be generated.
mysql-test/r/rpl_insert_id.result:
Add result for bug#21726: Incorrect result with multiple invocations
of LAST_INSERT_ID.
mysql-test/t/rpl_insert_id.test:
Add test case for bug#21726: Incorrect result with multiple invocations
of LAST_INSERT_ID.
sql/item_func.cc:
Add implementation of Item_func_last_insert_id::fix_fields(), where we
set THD::last_insert_id_used when statement calls LAST_INSERT_ID().
In Item_func_last_insert_id::val_int(), return THD::current_insert_id
if called like LAST_INSERT_ID(), otherwise return value of argument if
called like LAST_INSERT_ID(expr).
sql/item_func.h:
Add declaration of Item_func_last_insert_id::fix_fields().
sql/log_event.cc:
Do not set THD::last_insert_id_used on LAST_INSERT_ID_EVENT. Though we
know the statement will call LAST_INSERT_ID(), it wasn't called yet.
sql/set_var.cc:
In sys_var_last_insert_id::value_ptr(), set THD::last_insert_id_used,
and return THD::current_insert_id for @@LAST_INSERT_ID.
sql/sql_class.h:
Update comments.
Remove THD::insert_id(), as it has lost its purpose now.
sql/sql_insert.cc:
Now it is OK to read THD::last_insert_id directly.
sql/sql_load.cc:
Now it is OK to read THD::last_insert_id directly.
sql/sql_parse.cc:
In mysql_execute_command(), remember THD::last_insert_id (first
generated value of the previous statement) in THD::current_insert_id,
which then will be returned for LAST_INSERT_ID() and @@LAST_INSERT_ID.
sql/sql_select.cc:
If "IS NULL" is replaced with "= <LAST_INSERT_ID>", use right value,
which is THD::current_insert_id, and also set THD::last_insert_id_used
to issue binary log LAST_INSERT_ID_EVENT.
sql/sql_update.cc:
Now it is OK to read THD::last_insert_id directly.
tests/mysql_client_test.c:
Add test case for bug#21726: Incorrect result with multiple invocations
of LAST_INSERT_ID.

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.

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:

sql/sql_parse.cc:

so each can be protected by the same mutex.

Widen the scope of the mutex so that logging events are also protected.
sql/sql_trigger.cc:

invocations of LAST_INSERT_ID.
Reding of LAST_INSERT_ID inside stored function wasn't noted by caller,
and no LAST_INSERT_ID_EVENT was issued for binary log.
The solution is to add THD::last_insert_id_used_bin_log, which is much
like THD::last_insert_id_used, but is reset only for upper-level
statements. This new variable is used to issue LAST_INSERT_ID_EVENT.
mysql-test/r/rpl_insert_id.result:

Non-upper-level INSERTs (the ones in the body of stored procedure,
stored function, or trigger) into a table that have AUTO_INCREMENT
column didn't affected the result of LAST_INSERT_ID() on this level.
The problem was introduced with the fix of bug 6880, which in turn was
introduced with the fix of bug 3117, where current insert_id value was
remembered on the first call to LAST_INSERT_ID() (bug 3117) and was
returned from that function until it was reset before the next
_upper-level_ statement (bug 6880).
The fix for bug#21726 brings back the behaviour of version 4.0, and
implements the following: remember insert_id value at the beginning
of the statement or expression (which at that point equals to
the first insert_id value generated by the previous statement), and
return that remembered value from LAST_INSERT_ID() or @@LAST_INSERT_ID.
Thus, the value returned by LAST_INSERT_ID() is not affected by values
generated by current statement, nor by LAST_INSERT_ID(expr) calls in
this statement.
Version 5.1 does not have this bug (it was fixed by WL 3146).

Rather then remember current insert_id value on first invocation of
THD::insert_id(), remember it in Item_func_last_insert_id::fix_fields(),
sys_var_last_insert_id::value_ptr(), or mysql_execute_command().
Remove THD::insert_id(), as it lost its value now.
sql/sql_insert.cc:
THD::insert_id() is removed, use THD::last_insert_id directly.
sql/sql_load.cc:
THD::insert_id() is removed, using THD::last_insert_id directly is OK.
sql/sql_parse.cc:
Remember in THD::current_insert_id first generated insert id value of

No need to reset THD::last_insert_id_used in
mysql_reset_thd_for_next_command(), it will be reset after each

The cause of the bug was an incomplete fix for bug 18080.
The problem was that setup_tables() unconditionally reset the
name resolution context to its 'tables' argument, which pointed
to the first table of an SQL statement.
The bug fix limits resetting of the name resolution context in
setup_tables() only in the cases when the context was not set
by earlier parser/optimizer phases.
mysql-test/r/insert_select.result:
Test for BUG#21774.
mysql-test/t/insert_select.test:
Test for BUG#21774.
sql/sql_base.cc:
Do not reset the name resolution contect unconditionally.
Instead set the context to 'tables' only if it was not
set before calling setup_tables().
sql/sql_insert.cc:
Added asserts to make sure that in the case of INSERT ... VALUES ...
statements it is not necessary to reset the name resolution context
to the first table, because there is only one table in the list of
tables anyway. The actual code is not removed in order not to
confuse it with the actual bug fix.
sql/sql_parse.cc:
Removed unnecessary reset of the name resolution context.
The context is anyway unconditionally reset in mysql_insert()
and mysql_prepare_insert().
