Bug#4968 "Stored procedure crash if cursor opened on altered table"
Bug#19733 "Repeated alter, or repeated create/drop, fails"
Bug#19182 "CREATE TABLE bar (m INT) SELECT n FROM foo; doesn't work from
stored procedure."
Bug#6895 "Prepared Statements: ALTER TABLE DROP COLUMN does nothing"
Bug#22060 "ALTER TABLE x AUTO_INCREMENT=y in SP crashes server"
Test cases for bugs 4968, 19733, 6895 will be added in 5.0.
Re-execution of CREATE DATABASE, CREATE TABLE and ALTER TABLE
statements in stored routines or as prepared statements caused
incorrect results (and crashes in versions prior to 5.0.25).
In 5.1 the problem occured only for CREATE DATABASE, CREATE TABLE
SELECT and CREATE TABLE with INDEX/DATA DIRECTOY options).
The problem of bugs 4968, 19733, 19282 and 6895 was that functions
mysql_prepare_table, mysql_create_table and mysql_alter_table were not
re-execution friendly: during their operation they used to modify contents
of LEX (members create_info, alter_info, key_list, create_list),
thus making the LEX unusable for the next execution.
In particular, these functions removed processed columns and keys from
create_list, key_list and drop_list. Search the code in sql_table.cc
for drop_it.remove() and similar patterns to find evidence.
The fix is to supply to these functions a usable copy of each of the
above structures at every re-execution of an SQL statement.
To simplify memory management, LEX::key_list and LEX::create_list
were added to LEX::alter_info, a fresh copy of which is created for
every execution.
The problem of crashing bug 22060 stemmed from the fact that the above
metnioned functions were not only modifying HA_CREATE_INFO structure in
LEX, but also were changing it to point to areas in volatile memory of
the execution memory root.
The patch solves this problem by creating and using an on-stack
copy of HA_CREATE_INFO (note that code in 5.1 already creates and
uses a copy of this structure in mysql_create_table()/alter_table(),
but this approach didn't work well for CREATE TABLE SELECT statement).
mysql-test/r/ps.result:
Update test results (Bug#19182, Bug#22060)
mysql-test/t/ps.test:
Add a test case for Bug#19182, Bug#22060 (4.1-only parts)
sql/mysql_priv.h:
LEX::key_list and LEX::create_list were moved to LEX::alter_info.
Update declarations to use LEX::alter_info instead of these two
members.
sql/sql_class.h:
Replace pair<columns, keys> with an instance of Alter_info in
select_create constructor. We create a new copy of Alter_info
each time we re-execute SELECT .. CREATE prepared statement.
sql/sql_insert.cc:
Adjust to a new signature of create_table_from_items.
sql/sql_lex.cc:
Implement Alter_info::Alter_info that would make a "deep" copy
of all definition lists (keys, columns).
sql/sql_lex.h:
Move key_list and create_list to class Alter_info. Implement
Alter_info::Alter_info that can be used with PS and SP.
sql/sql_list.h:
Implement a copy constructor of class List that makes a deep copy
of all list nodes.
sql/sql_parse.cc:
Adjust to new signatures of mysql_create_table, mysql_alter_table,
select_create. Functions mysql_create_index and mysql_drop_index has
become identical after initialization of alter_info was moved to the
parser, and were merged. Flag enable_slow_log was not updated for
SQLCOM_DROP_INDEX, which is a bug. Just like CREATE INDEX, DROP INDEX
is currently done via complete table rebuild and is rightfully a slow
administrative statement.
sql/sql_show.cc:
Adjust mysqld_show_create_db to a new signature.
sql/sql_table.cc:
Adjust mysql_alter_table, mysql_recreate_table, mysql_create_table,
mysql_prepare_table to new signatures.
sql/sql_yacc.yy:
LEX::key_list and LEX::create_list moved to class Alter_info
--cursor_protocol": fix a misleading error message in case of
SELECT .. INTO.
sql/sql_class.cc:
Implement select_result::check_simple_select hierarchy to
support correct error messages in case of SELECT .. INTO and C API
cursors.
sql/sql_class.h:
Set the error message inside the function that checks for the error
condition (simple_select, renamed to check_simple_select).
sql/sql_prepare.cc:
Use a new method that now sets the error.
tests/mysql_client_test.c:
Add a test case for Bug#24179 "select b into $var" fails with
--cursor_protocol" (check for the right error message and error code).

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.

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

and return THD::current_insert_id for @@LAST_INSERT_ID.

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.

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).

"real" table fails in JOINs".
This is a regression caused by the fix for Bug 18444.
This fix removed the assignment of empty_c_string to table->db performed
in add_table_to_list, as neither me nor anyone else knew what it was
there for. Now we know it and it's covered with tests: the only case
when a table database name can be empty is when the table is a derived
table. The fix puts the assignment back but makes it a bit more explicit.
Additionally, finally drop sp.result.orig which was checked in by mistake.

To make MySQL compatible with some ODBC applications, you can find
the AUTO_INCREMENT value for the last inserted row with the following query:
SELECT * FROM tbl_name WHERE auto_col IS NULL.
This is done with a special code that replaces 'auto_col IS NULL' with
'auto_col = LAST_INSERT_ID'.
However this also resets the LAST_INSERT_ID to 0 as it uses it for a flag
so as to ensure that only the first SELECT ... WHERE auto_col IS NULL
after an INSERT has this special behaviour.
In order to avoid resetting the LAST_INSERT_ID a special flag is introduced
in the THD class. This flag is used to restrict the second and subsequent
SELECTs instead of LAST_INSERT_ID.

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.

Bug#19022 "Memory bug when switching db during trigger execution"
Bug#17199 "Problem when view calls function from another database."
Bug#18444 "Fully qualified stored function names don't work correctly in
SELECT statements"
Documentation note: this patch introduces a change in behaviour of prepared
statements.
This patch adds a few new invariants with regard to how THD::db should
be used. These invariants should be preserved in future:
- one should never refer to THD::db by pointer and always make a deep copy
(strmake, strdup)
- one should never compare two databases by pointer, but use strncmp or
my_strncasecmp
- TABLE_LIST object table->db should be always initialized in the parser or
by creator of the object.
For prepared statements it means that if the current database is changed
after a statement is prepared, the database that was current at prepare
remains active. This also means that you can not prepare a statement that
implicitly refers to the current database if the latter is not set.
This is not documented, and therefore needs documentation. This is NOT a
change in behavior for almost all SQL statements except:
- ALTER TABLE t1 RENAME t2
- OPTIMIZE TABLE t1
- ANALYZE TABLE t1
- TRUNCATE TABLE t1 --
until this patch t1 or t2 could be evaluated at the first execution of
prepared statement.
CURRENT_DATABASE() still works OK and is evaluated at every execution
of prepared statement.
Note, that in stored routines this is not an issue as the default
database is the database of the stored procedure and "use" statement
is prohibited in stored routines.
This patch makes obsolete the use of check_db_used (it was never used in the
old code too) and all other places that check for table->db and assign it
from THD::db if it's NULL, except the parser.
How this patch was created: THD::{db,db_length} were replaced with a
LEX_STRING, THD::db. All the places that refer to THD::{db,db_length} were
manually checked and:
- if the place uses thd->db by pointer, it was fixed to make a deep copy
- if a place compared two db pointers, it was fixed to compare them by value
(via strcmp/my_strcasecmp, whatever was approproate)
Then this intermediate patch was used to write a smaller patch that does the
same thing but without a rename.
TODO in 5.1:
- remove check_db_used
- deploy THD::set_db in mysql_change_db

sql/item_strfunc.cc:
Touch the code that reads thd->db (cleanup).
sql/log_event.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/slave.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/slave.h:
Remove a declaration for a method that is used only in one module.
sql/sp.cc:
Rewrite sp_use_new_db: this is a cleanup that I needed in order to understand
this function and ensure that it has no bugs.
sql/sp.h:
Add a new declaration for sp_use_new_db (uses LEX_STRINGs) and a comment.
sql/sp_head.cc:
- drop sp_name_current_db_new - a creator of sp_name class that was used
when sp_name was created for an identifier without an explicitly initialized
database. Now we pass thd->db to constructor of sp_name right in the
parser.
- rewrite sp_head::init_strings: name->m_db is always set now
- use the new variant of sp_use_new_db
- we don't need to update thd->db with SP MEM_ROOT pointer anymore when
parsing a stored procedure, as noone will refer to it (yes!)
sql/sp_head.h:
- remove unneded methods and members
sql/sql_class.h:
- introduce 3 THD methods to work with THD::db:
.set_db to assign the current database
.reset_db to reset the current database (temporarily) or set it to NULL
.opt_copy_db_to - to deep-copy thd->db to a pointer if it's not NULL
sql/sql_db.cc:
While we are at it, replace direct access to thd->db with a method.

sql/sql_lex.h:
- add a comment
sql/sql_parse.cc:
- implement the invariant described in the changeset comment.
- remove juggling with lex->sphead in SQLCOM_CREATE_PROCEDURE:
now db_load_routine uses its own LEX object and doesn't damage the main
LEX.
- add DBUG_ASSERT(0) to unused "check_db_used"
sql/sql_table.cc:
- replace a check with an assert (table_ident->db)
sql/sql_trigger.cc:
While we are at it, replace direct access to thd->db with a method.
Should simplify future conversion of THD::db to LEX_STRING.
sql/sql_udf.cc:
- use thd->set_db instead of direct modification of to thd->db
sql/sql_view.cc:
- replace a check with an assert (view->db)
sql/sql_yacc.yy:
- make sure that we always copy table->db or name->db or ident->db or
select_lex->db from thd->db if the former is not set. If thd->db
is not set but is accessed, return an error.
sql/tztime.cc:
- be nice, never copy thd->db by pointer.

too many open statements". The patch adds a new global variable
@@max_prepared_stmt_count. This variable limits the total number
of prepared statements in the server. The default value of
@@max_prepared_stmt_count is 16382. 16382 small statements
(a select against 3 tables with GROUP, ORDER and LIMIT) consume
100MB of RAM. Once this limit has been reached, the server will
refuse to prepare a new statement and return ER_UNKNOWN_ERROR
(unfortunately, we can't add new errors to 4.1 without breaking 5.0). The limit is changeable after startup
and can accept any value from 0 to 1 million. In case
the new value of the limit is less than the current
statement count, no new statements can be added, while the old
still can be used. Additionally, the current count of prepared
statements is now available through a global read-only variable
@@prepared_stmt_count.
mysql-test/r/ps.result:
Test results fixed (a test case for Bug#16365)
mysql-test/t/ps.test:
A test case for Bug#16365 "Prepared Statements: DoS with too many
open statements". Also fix statement leaks in other tests.
sql/mysql_priv.h:
Add declarations for new global variables.
sql/mysqld.cc:
Add definitions of max_prepared_stmt_count, prepared_stmt_count.
sql/set_var.cc:
Implement support for @@prepared_stmt_count and
@@max_prepared_stmt_count. Currently these variables are queried
without acquiring LOCK_prepared_stmt_count due to limitations of
the set_var/sys_var class design. Updates are, however, protected
with a lock.
sql/set_var.h:
New declarations to add support for @@max_prepared_stmt_count.
Implement a new class, where the lock to be used when updating
a variable is a parameter.
sql/sql_class.cc:
Add accounting of the total number of prepared statements in the
server to the methods of Statement_map.
sql/sql_class.h:
Add accounting of the total number of prepared statements in the

sql/sql_prepare.cc:
Statement_map::insert will now send a message in case of an

The GROUP_CONCAT uses its own temporary table. When ROLLUP is present
it creates the second copy of Item_func_group_concat. This copy receives the
same list of arguments that original group_concat does. When the copy is
set up the result_fields of functions from the argument list are reset to the
temporary table of this copy.
As a result of this action data from functions flow directly to the ROLLUP copy
and the original group_concat functions shows wrong result.
Since queries with COUNT(DISTINCT ...) use temporary tables to store
the results the COUNT function they are also affected by this bug.
The idea of the fix is to copy content of the result_field for the function
under GROUP_CONCAT/COUNT from the first temporary table to the second one,
rather than setting result_field to point to the second temporary table.
To achieve this goal force_copy_fields flag is added to Item_func_group_concat
and Item_sum_count_distinct classes. This flag is initialized to 0 and set to 1
into the make_unique() member function of both classes.
To the TMP_TABLE_PARAM structure is modified to include the similar flag as
well.
The create_tmp_table() function passes that flag to create_tmp_field().
When the flag is set the create_tmp_field() function will set result_field
as a source field and will not reset that result field to newly created
field for Item_func_result_field and its descendants. Due to this there
will be created copy func to copy data from old result_field to newly
created field.

sql/sql_table.cc:
Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries
Added 0 as a last parameter to create_tmp_field() to force old behaviour.
sql/sql_select.cc:
Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries
Added the flag 'make_copy_field' to create_tmp_field(), so that for Item_result_field descendants create_tmp_field() sets the item's result field as a source field and deny resetting that result field to a new value.
sql/sql_class.h:
Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries
Added the flag 'force_copy_fields' to the structure TMP_TABLE_PARAM in order to make create_tmp_field() force the creation of 'copy_field' objects.
sql/mysql_priv.h:
Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries
Added the bool parameter 'make_copy_field' to create_tmp_field().
sql/item_sum.cc:
Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries
Added initialization of the force_copy_fields flag and passing it to create_tmp_table() through TMP_TBLE_PARAM in the Item_func_group_concat and Item_sum_count_distinct member functions.
sql/item_sum.h:
Fixed bug#15560: GROUP_CONCAT wasn't ready for WITH ROLLUP queries
Added the flag 'force_copy_fields' to the Item_func_group_concat and Item_sum_count_distinct classes.
After the ChangeSet 1.1892.20.1 2005/08/24 (Bug #12562) SYSDATE() is not an alias
of NOW() and is unsafe for replication.
`SYSDATE()' backward compatible aliasing clashes with the idea #12562
fix. To make it safe-replicatable we have to either use RBR or to restore
the pre-5.0 style.
--sysdate-is-now command line flag was introduced to provide backward compatibility.
sql/mysqld.cc:
New option to force SYSDATE's backward compatible with 4.1 aliasing to NOW (not default)
sql/sql_class.h:
new slot to fill at init time and check at parse
