Bug#4968 ""Stored procedure crash if cursor opened on altered table"
Bug#6895 "Prepared Statements: ALTER TABLE DROP COLUMN does nothing"
Bug#19182 "CREATE TABLE bar (m INT) SELECT n FROM foo; doesn't work from
stored procedure."
Bug#19733 "Repeated alter, or repeated create/drop, fails"
Bug#22060 "ALTER TABLE x AUTO_INCREMENT=y in SP crashes server"
Bug#24879 "Prepared Statements: CREATE TABLE (UTF8 KEY) produces a
growing key length" (this bug is not fixed 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 are not
re-execution friendly: during their operation they 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 in mysql_execute_command.
Additionally, this patch splits the part of mysql_alter_table
that analizes and rewrites information from the parser into
a separate function - mysql_prepare_alter_table, in analogy with
mysql_prepare_table, which is renamed to mysql_prepare_create_table.

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 was a bug.
Just like CREATE INDEX, DROP INDEX is currently done via complete
table rebuild and is rightfully a slow administrative statement.
sql/sql_partition.cc:
Move is_partition_management() to sql_lex.cc
Adjust code to the new Alter_info.
sql/sql_table.cc:
Adjust mysql_alter_table, mysql_recreate_table, mysql_create_table,

Rename mysql_prepare_table to mysql_prepare_create_table. Make
sure it follows the convention and returns FALSE for success and
TRUE for error.
Move parts of mysql_alter_table to mysql_prepare_alter_table.
Move the first invokation of mysql_prepare_table from mysql_alter_table
to compare_tables, as it was needed only for the purpose
of correct comparison.
Since now Alter_info itself is created in the runtime mem root,
adjust mysql_prepare_table to always allocate memory in the
runtime memory root.
Remove dead code.
sql/sql_yacc.yy:
LEX::key_list and LEX::create_list moved to class Alter_info
The problem reported is a compile bug,
reported by the development GCC team with GCC 4.2.
The original issue can no longer be reproduced in MySQL 5.1,
since the configure script no longer define HAVE_ATOMIC_ADD,
which caused the Linux atomic functions to be used (and cause a problem
with an invalid cast).
This patch implements some code cleanup for 5.1 only, which was identified
during the investigation of this issue.
With this patch, statistics maintained in THD::status_var are by definition
owned by the running thread, and do not need to be protected against race
conditions. These statistics are maintained by the status_var_* helpers,
which do not require any lock.

Bug#21483 "Server abort or deadlock on INSERT DELAYED with another
implicit insert"
Also fixes and adds test cases for bugs:
20497 "Trigger with INSERT DELAYED causes Error 1165"
21714 "Wrong NEW.value and server abort on INSERT DELAYED to a
table with a trigger".
Post-review fixes.
Problem:
In MySQL INSERT DELAYED is a way to pipe all inserts into a
given table through a dedicated thread. This is necessary for
simplistic storage engines like MyISAM, which do not have internal
concurrency control or threading and thus can not
achieve efficient INSERT throughput without support from SQL layer.
DELAYED INSERT works as follows:
For every distinct table, which can accept DELAYED inserts and has
pending data to insert, a dedicated thread is created to write data
to disk. All user connection threads that attempt to
delayed-insert into this table interact with the dedicated thread in
producer/consumer fashion: all records to-be inserted are pushed
into a queue of the dedicated thread, which fetches the records and
writes them.
In this design, client connection threads never open or lock
the delayed insert table.
This functionality was introduced in version 3.23 and does not take
into account existence of triggers, views, or pre-locking.
E.g. if INSERT DELAYED is called from a stored function, which,
in turn, is called from another stored function that uses the delayed
table, a deadlock can occur, because delayed locking by-passes
pre-locking. Besides:
* the delayed thread works directly with the subject table through
the storage engine API and does not invoke triggers
* even if it was patched to invoke triggers, if triggers,
in turn, used other tables, the delayed thread would
have to open and lock involved tables (use pre-locking).
* even if it was patched to use pre-locking, without deadlock
detection the delayed thread could easily lock out user
connection threads in case when the same table is used both
in a trigger and on the right side of the insert query:
the delayed thread would not release locks until all inserts
are complete, and user connection can not complete inserts
without having locks on the tables used on the right side of the
query.
Solution:
These considerations suggest two general alternatives for the
future of INSERT DELAYED:
* it is considered a full-fledged alternative to normal INSERT
* it is regarded as an optimisation that is only relevant
for simplistic engines.
Since we missed our chance to provide complete support of new
features when 5.0 was in development, the first alternative
currently renders infeasible.
However, even the second alternative, which is to detect
new features and convert DELAYED insert into a normal insert,
is not easy to implement.
The catch-22 is that we don't know if the subject table has triggers
or is a view before we open it, and we only open it in the
delayed thread. We don't know if the query involves pre-locking
until we have opened all tables, and we always first create
the delayed thread, and only then open the remaining tables.
This patch detects the problematic scenarios and converts
DELAYED INSERT to a normal INSERT using the following approach:
* if the statement is executed under pre-locking (e.g. from
within a stored function or trigger) or the right
side may require pre-locking, we detect the situation
before creating a delayed insert thread and convert the statement
to a conventional INSERT.
* if the subject table is a view or has triggers, we shutdown
the delayed thread and convert the statement to a conventional
INSERT.
mysql-test/r/insert.result:

correctly

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

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.
mysql-test/r/create_select-big.result:
New BitKeeper file ``mysql-test/r/create_select-big.result''
mysql-test/t/create_select-big.test:
New BitKeeper file ``mysql-test/t/create_select-big.test''

Deadlock occured when one tried to execute CREATE TABLE IF 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.
Also note that we decided to postpone introduction of some tests
for concurrent behaviour of CREATE TABLE ... SELECT till 5.1.
The main reason for this is absence in 5.0 ability to set @@debug
variable at runtime, which can be circumvented only by using several
test files with individual .opt files. Since the latter is likely
to slowdown test-suite unnecessary we chose not to push this tests
into 5.0, but run them manually for this version and later push
their optimized version into 5.1
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

mysql-test/t/trigger.test:
Added test case for bug #20903 "Crash when using CREATE TABLE .. SELECT

sql/lock.cc:
Now for creation of name-lock placeholder in lock_table_name() we use
auxiliary function table_cache_insert_placeholder().
sql/mysql_priv.h:
Made build_table_path() function available outside of sql_table.cc file.
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 table_cache_has_open_placeholder() function which
can be used for checking if table cache contains an open placeholder for
the table and if this placeholder was created by another thread.
(This function is needed only in 5.0 where we use it in various versions
of CREATE TABLE in order to protect it from concurrent CREATE TABLE
... SELECT operations for the table. Starting from 5.1 we use different
approach so it is going to be removed there).
Made close_old_data_files() static within sql_base.cc file.
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).
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 table_cache_has_open_placeholder() function which can be
used for checking if table cache contains an open placeholder for
the table and if this placeholder was created by another thread.
(This function is needed only in 5.0 where we use it in various versions
of CREATE TABLE in order to protect it from concurrent CREATE TABLE
... SELECT operations for the table. Starting from 5.1 we use different
approach so it is going to be removed there).
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 select_create methods 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:
Now mysql_create_table_internal(), mysql_create_like_table() and
mysql_alter_table() not only check that destination table doesn't
exist on disk but also check that there is no create placeholder
in table cache for it (i.e. there is no CREATE TABLE ... SELECT
operation in progress for it). Note that starting from 5.1 we
use different approach in order to to protect CREATE TABLE ... SELECT
from concurrent CREATE TABLE (ALTER TABLE ... RENAME) operations,
the latter simply take name-locks on table before its creation
(on target table name before renaming).
Also made build_table_path() available from other files and
asjusted calls to reopen_name_locked_table(), which now takes
extra argument, which controls linking of open table into
THD::open_tables list.
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()).

Bug occurs in INSERT IGNORE ... SELECT ... ON DUPLICATE KEY UPDATE
statements, when SELECT returns duplicated values and UPDATE clause
tries to assign NULL values to NOT NULL fields.
NOTE: By current design MySQL server treats INSERT IGNORE ... ON
DUPLICATE statements as INSERT ... ON DUPLICATE with update of
duplicated records, but MySQL manual lacks this information.
After this fix such behaviour becomes legalized.
The write_record() function was returning error values even within
INSERT IGNORE, because ignore_errors parameter of
the fill_record_n_invoke_before_triggers() function call was
always set to FALSE. FALSE is replaced by info->ignore.

skipped):
By moving statement end actions from Rows_log_event::do_apply_event() to
Rows_log_event::do_update_pos() they will always be executed, even if
Rows_log_event::do_apply_event() is skipped because the event originated
at the same server. This because Rows_log_event::do_update_pos() is always
executed (unless Rows_log_event::do_apply_event() failed with an error,
in which case the slave stops with an error anyway).
Adding test case.
Fixing logic to detect if inside a group. If a rotate event occured
when an initial prefix of events for a statement, but for which the
table did contain a key, last_event_start_time is set to zero, causing
rotate to end the group but without unlocking any tables. This left a
lock hanging around, which subsequently triggered an assertion when a
second attempt was made to lock the same sequence of tables.
In order to solve the above problem, a new flag was added to the relay
log info structure that is used to indicate that the replication thread
is currently executing a statement. Using this flag, the replication
thread is in a group if it is either in a statement or inside a trans-
action.
The patch also eliminates some gratuitous header file inclusions that
were not needed (and caused compile errors) and replaced them with
forward definitions.

In certain cases AFTER UPDATE/DELETE triggers on NDB tables that referenced
subject table didn't see the results of operation which caused invocation
of those triggers. In other words AFTER trigger invoked as result of update
(or deletion) of particular row saw version of this row before update (or
deletion).
The problem occured because NDB handler in those cases postponed actual
update/delete operations to be able to perform them later as one batch.
This fix solves the problem by disabling this optimization for particular
operation if subject table has AFTER trigger for this operation defined.
To achieve this we introduce two new flags for handler::extra() method:
HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH.
These are called if there exists AFTER DELETE/UPDATE triggers during a
statement that potentially can generate calls to delete_row()/update_row().
This includes multi_delete/multi_update statements as well as insert statements
that do delete/update as part of an ON DUPLICATE statement.
include/my_base.h:
Added HA_EXTRA_DELETE_CANNOT_BATCH and HA_EXTRA_UPDATE_CANNOT_BATCH to inform handler when batching of delete/update is not possible.

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.

thd->options' OPTION_STATUS_NO_TRANS_UPDATE bit was not restored at the end of SF() invocation, where
SF() modified non-ta table.
As the result of this artifact it was not possible to detect whether there were any side-effects when
top-level query ends.
If the top level query table was not modified and the bit is lost there would be no binlogging.
Fixed with preserving the bit inside of thd->no_trans_update struct. The struct agregates two bool flags
telling whether the current query and the current transaction modified any non-ta table.
The flags stmt, all are dropped at the end of the query and the transaction.

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.
