The problem is that a SELECT on one thread is blocked by INSERT ... ON
DUPLICATE KEY UPDATE on another thread even when low_priority_updates is
activated.
The solution is to possibly downgrade the lock type to the setting of
low_priority_updates if the INSERT cannot be concurrent.

SQL_MODE was ignored when a client issued INSERT DELAYED.
Some system settings weren't copied as intended when a record was saved for
a delayed insert.
mysql-test/r/delayed.result:
Added test case
mysql-test/t/delayed.test:

sql/sql_insert.cc:
- Added two new variables (sql_mode, auto_increment_field_not_null) to support
SQL_MODE in INSERT DELAYED statements.
SQL_MODE was ignored when a client issued INSERT DELAYED.
Some system settings weren't copied as intended when a record was saved for

Binlogging of the statement with a side effect like a modified non-trans table did not happen.
The artifact involved all binloggable dml queries.
Fixed with changing the binlogging conditions all over the code to exploit thd->transaction.stmt.modified_non_trans_table
introduced by the patch for bug@27417.
Multi-delete case has own specific addressed by another bug@29136. Multi-update case has been addressed by bug#27716 and
patch and will need merging.

Before we only did this if there was other pending alarms.
We don't have to use pthread_sigmask() in case of 'USE_ONE_SIGNAL_HAND' as the alarm()

INSERT DELAYED on a replication slave was converted to regular INSERT,
whereas it should try concurrent INSERT first.
With this patch we try to convert delayed insert to concurrent insert on
a replication slave. If it is impossible for some reason, we fall back to
regular insert.
No test case for this fix. I do not see anything indicating this is
regression - we behave this way since Nov 2000.
sql/sql_insert.cc:
If we're executing INSERT DELAYED on a replication slave, we're upgrading
lock type to TL_WRITE as we need to ensure serial execution of queries on
the slave.
OTOH if we're executing regular INSERT on a replication slave, we're
trying TL_WRITE_CONCURRENT_INSERT first, and if we may not use it, we
fall back to TL_WRITE.
Fixed INSERT DELAYED on a replication slave to behave the same way as
regular INSERT, that is to try TL_WRITE_CONCURRENT_INSERT first.

Bug #27417 thd->no_trans_update.stmt lost value inside of SF-exec-stack
Once had been set the flag might later got reset inside of a stored routine
execution stack.
The reason was in that there was no check if a new statement started at time
of resetting.
The artifact affects most of binlogable DML queries. Notice, that multi-update
is wrapped up within
bug@27716 fix, multi-delete bug@29136.
Fixed with saving parent's statement flag of whether the statement modified
non-transactional table, and unioning (merging) the value with that was gained
in mysql_execute_command.
Resettling thd->no_trans_update members into thd->transaction.`member`;
Asserting code;
Effectively the following properties are held.
1. At the end of a substatement thd->transaction.stmt.modified_non_trans_table
reflects the fact if such a table got modified by the substatement.
That also respects THD::really_abort_on_warnin() requirements.
2. Eventually thd->transaction.stmt.modified_non_trans_table will be computed as
the union of the values of all invoked sub-statements.
That fixes this bug#27417;
Computing of thd->transaction.all.modified_non_trans_table is refined to base to
the stmt's value for all the case including insert .. select statement which
before the patch had an extra issue bug@28960.
Minor issues are covered with mysql_load, mysql_delete, and binloggin of insert in
to temp_table select.
The supplied test verifies limitely, mostly asserts. The ultimate testing is defered
for bug@13270, bug@23333.

correcting basic delete incl truncate branch and multi-delete queries to set
stmt.modified_non_trans_table;
optimization to set the flag at the end of per-row loop;
multi-delete still has an extra issue similar to bug#27716 of multi-update
- to be address with bug_29136 fix.
sql/sql_insert.cc:
thd->transaction.{all,stmt}.modified_non_trans_table
instead of
thd->no_trans_update.{all,stmt}
sql/sql_load.cc:
eliminating a separate issue where the stmt flag was saved and re-stored after
write_record that actually could change it and the change would be lost but
should remain permanent;
thd->transaction.{all,stmt}.modified_non_trans_table
instead of
thd->no_trans_update.{all,stmt}
sql/sql_parse.cc:
initialization to transaction.stmt.modified_non_trans_table at the common part
of all types of statements processing - mysql_execute_command().
sql/sql_table.cc:
moving the reset up to the mysql_execute_command() caller
sql/sql_update.cc:
correcting update query case (multi-update part of the issues covered by other
bug#27716 fix)
thd->transaction.{all,stmt}.modified_non_trans_table
instead of
thd->no_trans_update.{all,stmt}
Bug #27417 thd->no_trans_update.stmt lost value inside of SF-exec-stack
Once had been set the flag might later got reset inside of a stored routine
execution stack.
The reason was in that there was no check if a new statement started at time
of resetting.
The artifact affects most of binlogable DML queries. Notice, that multi-update
is wrapped up within
bug@27716 fix, multi-delete bug@29136.
Fixed with saving parent's statement flag of whether the statement modified
non-transactional table, and unioning (merging) the value with that was gained
in mysql_execute_command.
Resettling thd->no_trans_update members into thd->transaction.`member`;
Asserting code;
Effectively the following properties are held.
1. At the end of a substatement thd->transaction.stmt.modified_non_trans_table
reflects the fact if such a table got modified by the substatement.
That also respects THD::really_abort_on_warnin() requirements.
2. Eventually thd->transaction.stmt.modified_non_trans_table will be computed as
the union of the values of all invoked sub-statements.
That fixes this bug#27417;
Computing of thd->transaction.all.modified_non_trans_table is refined to base to
the stmt's value for all the case including insert .. select statement which
before the patch had an extra issue bug@28960.
Minor issues are covered with mysql_load, mysql_delete, and binloggin of insert in
to temp_table select.
The supplied test verifies limitely, mostly asserts. The ultimate testing is defered
for bug@13270, bug@23333.

Bug#25422 (Hang with log tables)
Bug 17876 (Truncating mysql.slow_log in a SP after using cursor locks the
thread)
Bug 23044 (Warnings on flush of a log table)
Bug 29129 (Resetting general_log while the GLOBAL READ LOCK is set causes
a deadlock)
Prior to this fix, the server would hang when performing concurrent
ALTER TABLE or TRUNCATE TABLE statements against the LOG TABLES,
which are mysql.general_log and mysql.slow_log.
The root cause traces to the following code:
in sql_base.cc, open_table()
if (table->in_use != thd)
{
/* wait_for_condition will unlock LOCK_open for us */
wait_for_condition(thd, &LOCK_open, &COND_refresh);
}
The problem with this code is that the current implementation of the
LOGGER creates 'fake' THD objects, like
- Log_to_csv_event_handler::general_log_thd
- Log_to_csv_event_handler::slow_log_thd
which are not associated to a real thread running in the server,
so that waiting for these non-existing threads to release table locks
cause the dead lock.
In general, the design of Log_to_csv_event_handler does not fit into the
general architecture of the server, so that the concept of general_log_thd
and slow_log_thd has to be abandoned:
- this implementation does not work with table locking
- it will not work with commands like SHOW PROCESSLIST
- having the log tables always opened does not integrate well with DDL
operations / FLUSH TABLES / SET GLOBAL READ_ONLY
With this patch, the fundamental design of the LOGGER has been changed to:
- always open and close a log table when writing a log
- remove totally the usage of fake THD objects
- clarify how locking of log tables is implemented in general.
See WL#3984 for details related to the new locking design.
Additional changes (misc bugs exposed and fixed):
1)
mysqldump which would ignore some tables in dump_all_tables_in_db(),
but forget to ignore the same in dump_all_views_in_db().
2)
mysqldump would also issue an empty "LOCK TABLE" command when all the tables
to lock are to be ignored (numrows == 0), instead of not issuing the query.
3)
Internal errors handlers could intercept errors but not warnings
(see sql_error.cc).
4)
Implementing a nested call to open tables, for the performance schema tables,
exposed an existing bug in remove_table_from_cache(), which would perform:
in_use->some_tables_deleted=1;
against another thread, without any consideration about thread locking.
This call inside remove_table_from_cache() was not required anyway,
since calling mysql_lock_abort() takes care of aborting -- cleanly -- threads
that might hold a lock on a table.
This line (in_use->some_tables_deleted=1) has been removed.

MySQL can decide to "downgrade" a INSERT DELAYED statement
to normal insert in certain situations.
One such situation is when the slave is replaying a
replication feed.
However INSERT DELAYED is logged even if there're no updates
whereas the NORMAL INSERT is not logged in such cases.
