Bug #20662 "Infinite loop in CREATE TABLE IF NOT EXISTS ... SELECT
with locked tables"
Bug #20903 "Crash when using CREATE TABLE .. SELECT and triggers"
Bug #24738 "CREATE TABLE ... SELECT is not isolated properly"
Bug #24508 "Inconsistent results of CREATE TABLE ... SELECT when
temporary table exists"
Deadlock occured when one tried to execute CREATE TABLE IF NOT
EXISTS ... SELECT statement under LOCK TABLES which held
read lock on target table.
Attempt to execute the same statement for already existing
target table with triggers caused server crashes.
Also concurrent execution of CREATE TABLE ... SELECT statement
and other statements involving target table suffered from
various races (some of which might've led to deadlocks).
Finally, attempt to execute CREATE TABLE ... SELECT in case
when a temporary table with same name was already present
led to the insertion of data into this temporary table and
creation of empty non-temporary table.
All above problems stemmed from the old implementation of CREATE
TABLE ... SELECT in which we created, opened and locked target
table without any special protection in a separate step and not
with the rest of tables used by this statement.
This underminded deadlock-avoidance approach used in server
and created window for races. It also excluded target table
from prelocking causing problems with trigger execution.
The patch solves these problems by implementing new approach to
handling of CREATE TABLE ... SELECT for base tables.
We try to open and lock table to be created at the same time as
the rest of tables used by this statement. If such table does not
exist at this moment we create and place in the table cache special
placeholder for it which prevents its creation or any other usage
by other threads.
We still use old approach for creation of temporary tables.
Note that we have separate fix for 5.0 since there we use slightly
different less intrusive approach.
mysql-test/r/create.result:
Extended test coverage for CREATE TABLE ... SELECT. In particular added
tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT
when temporary table exists" and bug #20662 "Infinite loop in CREATE
TABLE IF NOT EXISTS ... SELECT with locked tables".
mysql-test/r/trigger.result:
Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT
and triggers"
mysql-test/t/create.test:
Extended test coverage for CREATE TABLE ... SELECT. In particular added
tests for bug #24508 "Inconsistent results of CREATE TABLE ... SELECT
when temporary table exists" and bug #20662 "Infinite loop in CREATE
TABLE IF NOT EXISTS ... SELECT with locked tables".
mysql-test/t/trigger.test:
Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT
and triggers"
sql/lock.cc:
Now for creation of name-lock placeholder lock_table_name() uses
auxiliary function table_cache_insert_placeholder().
sql/mysql_priv.h:
Removed declaration of non-existing build_table_path() routine.
The former mysql_create_table_internal() was renamed to
mysql_create_table_no_lock() and now exposed to other modules to
give them opportunity of creation of tables in cases when name-lock
is already obtained.
reopen_name_locked_table() now has 3rd argument which controls linking
in of table being opened into THD::open_tables (this is useful in
cases when placeholder used for name-locking is already linked into
this list).
Added declaration of auxiliary function table_cache_insert_placeholder()
which is used for creation of table placeholders for name-locking.
Added declaration of lock_table_name_if_not_cached() which can be
used to take an exclusive name-lock on table if there are no records
for it in table cache.
Changed signature of unlink_open_table() function to simplify its use
and make it useful for table placeholders and tables that are only open.
Added auxiliary drop_open_table() routine.
Moved declaration of refresh_version to table.h header to make it
accessible from inline methods of TABLE class.
MYSQL_OPEN_IGNORE_LOCKED_TABLES flag is no longer used. Instead
MYSQL_OPEN_TEMPORARY_ONLY option was added.
sql/sql_base.cc:
Added support for the new approach to the handling of CREATE TABLE
... SELECT for base tables.
Now we try to open and lock table to be created at the same time as
the rest of tables used by this statement. If such table does not
exist at this moment we create and place in the table cache special
placeholder for it which prevents its creation or any other usage
by other threads.
Note significant distinctions of this placeholder from the placeholder
used for normal name-lock: 1) It is treated like open table by other
name-locks so it does not allow name-lock taking operations like DROP
TABLE or RENAME TABLE to proceed. 2) it is linked into THD::open_tables
list and automatically removed during close_thread_tables() call
open_tables():
Implemented logic described above. To do this added
auxiliary check_if_table_exists() function.
Removed support for MYSQL_OPEN_IGNORE_LOCKED_TABLES option
which is no longer used.
Added MYSQL_OPEN_TEMPORARY_ONLY which is used to restrict
search for temporary tables only.
close_cached_tables()/close_thread_table()/reopen_tables()/
close_old_data_files()/table_is_used()/remove_table_from_cache():
Added support for open placeholders (note that we also use them
when we need to re-open tables during flush).
unlink_open_table():
Changed function signature to simplify its use and to make
useful for open placeholders and tables which are only
open and not locked.
Added auxiliary drop_open_table() routine.
reopen_name_locked_table():
Now has 3rd argument which controls linking in of table being
opened into THD::open_tables (this is useful in cases when
placeholder used for name-locking is already linked into
this list).
Added auxiliary table_cache_insert_placeholder() routine which
simplifies creation of placeholders used for name-locking.
Added lock_table_name_if_not_cached() which can be used to take
an exclusive name-lock on table if there are no records for it
in table cache.
sql/sql_handler.cc:
Adjusted mysql_ha_mark_tables_for_reopen() routine to properly
handle placeholders which now can be linked into open tables
list.
sql/sql_insert.cc:
Introduced new approach to handling of base tables in CREATE TABLE
... SELECT statement.
Now we try to open and lock table to be created at the same time as
the rest of tables used by this statement. If such table does not
exist at this moment we create and place in the table cache special
placeholder for it which prevents its creation or any other usage
by other threads. By doing this we avoid races which existed with
previous approach in which we created, opened and locked target in
separate step without any special protection.
This also allows properly calculate prelocking set in cases when
target table already exists and has some on insert triggers.
Note that we don't employ the same approach for temporary tables
(this is okay as such tables are unaffected by other threads).
Changed create_table_from_items() and methods of select_create
class to implement this approach.
sql/sql_parse.cc:
The new approach to handling of CREATE TABLE ... SELECT for
base tables assumes that all tables (including table to be
created) are opened and (or) locked at the same time.
So in cases when we create base table we have to pass to
open_and_lock_tables() table list which includes target table.
sql/sql_prepare.cc:
The new approach to handling of CREATE TABLE ... SELECT for
base tables assumes that all tables (including table to be
created) are opened and (or) locked at the same time.
So in cases when we create base table we have to pass to
open_and_lock_tables() table list which includes target table.
sql/sql_table.cc:
Changed mysql_create_table(), mysql_create_like_table() and
mysql_alter_table() (in rename case) to obtain exclusive name-lock
on the non-temporary table which is going to be created (to which
we going to rename). This ensures that not only destination table
doesn't exist on disk but also that there are no placeholder in
table cache for it (i.e. there is no CREATE TABLE ... SELECT operation
in progress for it). Note that to avoid deadlocks while taking these
name-locks this code assumes that existence of any record for table in
table cache (even name-lock) means that table exists. Altough such
check can lead to false positives these should occur only in case of
highly concurrent DDL operations on the table and should not break
binary logging.
Renamed mysql_create_table_internal() to mysql_create_table_no_lock()
and made it accessible from other files to give them ability to create
table in situation when name-lock is already obtained or not relevant.
Adjusted calls to reopen_name_locked_table(), which now takes
extra argument, which controls linking of open table into
THD::open_tables list.
Removed redundant setting of table's 'version' field before calls
to close_cached_table(). This function will set it to 0 itself
anyway.
sql/sql_trigger.cc:
reopen_name_locked_tables() now has one more argument which controls
linking of opened table into the THD::open_tables list.
sql/sql_yacc.yy:
The new approach to handling of CREATE TABLE ... SELECT statement
for base tables assumes that all tables including table to be
created are open and (or) locked at the same time. Therefore
we need to set correct lock for target table.
sql/table.h:
Moved declaration of refresh_version variable from mysql_priv.h
to make it accessible from inline methods of TABLE class.
Renamed TABLE::locked_by_flush member to open_placeholder since
now it is also used for taking exclusive name-lock and not only
by flush.
Introduced TABLE::is_name_opened() helper method which can be used
to distinguish TABLE instances corresponding to open tables or
placeholders for them from closed instances (e.g. due to their old
version). Also introduced TABLE::needs_reopen_or_name_lock() helper
which allows to check if TABLE instance corresponds to outdated
version of table or to name-lock placeholder.
Introduced TABLE_LIST::create member which marks elements of
table list corresponds to the table to be created.
Adjusted TABLE_LIST::placeholder() method to take into account
name-lock placeholders for tables to be created (this, for example,
allows to properly handle such placeholders in lock_tables()).
Finally, moved currently unused TABLE::open_next/open_prev
members under ifdef NOT_YET.

NO_AUTO_VALUE_ON_ZERO mode.
In the NO_AUTO_VALUE_ON_ZERO mode the table->auto_increment_field_not_null
variable is used to indicate that a non-NULL value was specified by the user
for an auto_increment column. When an INSERT .. ON DUPLICATE updates the
auto_increment field this variable is set to true and stays unchanged for the
next insert operation. This makes the next inserted row sometimes wrongly have
0 as the value of the auto_increment field.
Now the fill_record() function resets the table->auto_increment_field_not_null
variable before filling the record.
The table->auto_increment_field_not_null variable is also reset by the
open_table() function for a case if we missed some auto_increment_field_not_null
handling bug.
Now the table->auto_increment_field_not_null is reset at the end of the
mysql_load() function.
Reset the table->auto_increment_field_not_null variable after each
write_row() call in the copy_data_between_tables() function.

sql/sql_base.cc:
BUG #26257 New Federated Server Functionality Doesn't support differently named tables
new function: close_cached_connection_tables()
closes all open tables which match connection string
provides functionality to allow flushing of altered/dropped server names.
sql/sql_servers.cc:
BUG #26257 New Federated Server Functionality Doesn't support differently named tables
* Added function clone_server() to allocate a new server for use by
get_server_by_name() when creating a federated table
* Now using MEM_ROOT allocation (mark and sweep) to account for meta
data parameters being allocated properly, particularly with regards to
to SERVER object. Also cleans up code allocating share.
* Tables using the old definition of server name are now flushed on successful
execution of ALTER/DROP SERVER.
style: fixed some line-wrapping
sql/sql_servers.h:
BUG #26257 New Federated Server Functionality Doesn't support differently named tables
* change in prototype to get_server_by_name()
caller can now provide mem_root which strings will be copied in to.
storage/federated/ha_federated.cc:
BUG #26257 New Federated Server Functionality Doesn't support differently named tables
* Simplified share and share member memory allocaton to use MEM_ROOT
* Modified parse_url to parse table names along with server names
storage/federated/ha_federated.h:
BUG #26257 New Federated Server Functionality Doesn't support differently named tables
* Added MEM_ROOT share member
Made year 2000 handling more uniform
Removed year 2000 handling out from calc_days()
The above removes some bugs in date/datetimes with year between 0 and 200
Now we get a note when we insert a datetime value into a date column
For default values to CREATE, don't give errors for warning level NOTE
Fixed some compiler failures
Added library ws2_32 for windows compilation (needed if we want to compile with IOCP support)
Removed duplicate typedef TIME and replaced it with MYSQL_TIME
Better (more complete) fix for: Bug#21103 "DATE column not compared as DATE"
Fixed properly Bug#18997 "DATE_ADD and DATE_SUB perform year2K autoconversion magic on 4-digit year value"
Fixed Bug#23093 "Implicit conversion of 9912101 to date does not match cast(9912101 as date)"

To correctly decide which predicates can be evaluated with a given table
the optimizer must know the exact set of tables that a predicate depends
on. If that mask is too wide (refer to non-existing tables) the optimizer
can erroneously skip a predicate.
One such case of wrong table usage mask were the aggregate functions.
The have a all-1 mask (meaning depend on all tables, including non-existent
ones).
Fixed by making a real used_tables mask for the aggregates. The mask is
constructed in the following way :
1. OR the table dependency masks of all the arguments of the aggregate.
2. If all the arguments of the function are from the local name resolution
context and it is evaluated in the same name resolution
context where it is referenced all the tables from that name resolution
context are OR-ed to the dependency mask. This is to denote that an
aggregate function depends on the number of rows it processes.
3. Handle correctly the case of an aggregate function optimization (such that
the aggregate function can be pre-calculated and made a constant).
Made sure that an aggregate function is never a constant (unless subject of a
specific optimization and pre-calculation).
One other flaw was revealed and fixed in the process : references were
not calling the recalculation method for used_tables of their targets.

The problem was that some facilities (like CONVERT_TZ() function or
server HELP statement) may require implicit access to some tables in
'mysql' database. This access was done by ordinary means of adding
such tables to the list of tables the query is going to open.
However, if we issued LOCK TABLES before that, we would get "table
was not locked" error trying to open such implicit tables.
The solution is to treat certain tables as MySQL system tables, like
we already do for mysql.proc. Such tables may be opened for reading
at any moment regardless of any locks in effect. The cost of this is
that system table may be locked for writing only together with other
system tables, it is disallowed to lock system tables for writing and
have any other lock on any other table.
After this patch the following tables are treated as MySQL system
tables:
mysql.help_category
mysql.help_keyword
mysql.help_relation
mysql.help_topic
mysql.proc (it already was)
mysql.time_zone
mysql.time_zone_leap_second
mysql.time_zone_name
mysql.time_zone_transition
mysql.time_zone_transition_type
These tables are now opened with open_system_tables_for_read() and
closed with close_system_tables(), or one table may be opened with
open_system_table_for_update() and closed with close_thread_tables()
(the latter is used for mysql.proc table, which is updated as part of
normal MySQL server operation). These functions may be used when
some tables were opened and locked already.
NOTE: online update of time zone tables is not possible during
replication, because there's no time zone cache flush neither on LOCK
TABLES, nor on FLUSH TABLES, so the master may serve stale time zone
data from cache, while on slave updated data will be loaded from the
time zone tables.

Change the error message, as now we allow write-locking of several
system tables if not mixed with ordinary tables.
sql/tztime.cc:
Do not add time zone tables to the list of query tables in
tz_init_table_list().
Remove fake_time_zone_tables_list and my_tz_get_tables_list().
In my_tz_init(), open mysql.time_zone_leap_second with
simple_open_n_lock_tables(), but pass time zone name to my_tz_find(),
which will open and close time zone tables as necessary.
In tz_load_from_open_tables() do not call table->use_all_columns(), as
this was already done in open_system_tables_for_read().
my_tz_find() takes THD pointer instead of table list, and calls
open_system_tables_for_read() and close_system_tables() as necessary.
Remove my_tz_find_with_opening_tz_tables().
sql/tztime.h:
Remove declarations of my_tz_get_table_list(),
my_tz_find_with_opening_tz_tables(), fake_time_zone_tables_list,
definition of my_tz_check_n_skip_implicit_tables().
Update prototype for my_tz_find().
storage/csv/ha_tina.cc:
Add new parameters to check_if_locking_is_allowed().
storage/csv/ha_tina.h:
Add new parameters to check_if_locking_is_allowed().
storage/myisam/ha_myisam.cc:
Add new parameters to check_if_locking_is_allowed(). In this
function we count system tables. If there are system tables, but
there are also non-system tables, we report an error.
storage/myisam/ha_myisam.h:
Add new parameters to check_if_locking_is_allowed().
include/my_global.h:
Introduce constants to be used instead of magic numbers.
sql/field.cc:
Polishing: use contants instead of magic numbers.
sql/ha_innodb.cc:
Polishing: use contants instead of magic numbers.
sql/handler.cc:
Polishing: use contants instead of magic numbers.
