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

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.
mysql-test/r/subselect.result:
Added a test case for bug #21727.

of which requires filesort.
Added an implementation for Item_subselect::is_uncacheable()
returning TRUE if the engine if the subselect is uncacheable.
sql/mysql_priv.h:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added a new boolean parameter to the filesort_free_buffers procedure.
If the value of this parameter is TRUE the procedure frees the sort_keys
buffpek buffers.
sql/records.cc:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added a new boolean parameter to the filesort_free_buffers procedure.
If the value of this parameter is TRUE the procedure frees the sort_keys
buffpek buffers.
sql/sql_base.cc:
Fixed bug #21727.
Made sure that st_table::pos_in_table_list would be always initialized.
sql/sql_select.cc:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added a new boolean parameter to the filesort_free_buffers procedure.
If the value of this parameter is TRUE the procedure frees the sort_keys
buffpek buffers.
sql/sql_show.cc:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added a new boolean parameter to the filesort_free_buffers procedure.
If the value of this parameter is TRUE the procedure frees the sort_keys
buffpek buffers.
sql/sql_table.cc:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Cleanup.
sql/table.cc:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added st_table_list::in_subselect() returning for a table the subselect that
contains the FROM list this table is taken from (if there is any).
sql/table.h:
Fixed bug #21727.
This is a performance issue for queries with subqueries evaluation
of which requires filesort.
Added fields for sort_keys and buffpek buffers to the FILESORT_INFO structure.
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.
