INSERT/DELETE/UPDATE followed by ALTER TABLE within LOCK TABLES
may cause table corruption on Windows.
That happens because ALTER TABLE writes outdated shared state
info into index file.
Fixed by removing obsolete workaround.
Affects MyISAM tables on Windows only.
myisam/mi_extra.c:
On windows when mi_extra(HA_EXTRA_PREPARE_FOR_DELETE) is called,
we release external lock and close index file. If we're in LOCK
TABLES, MyISAM state info doesn't get updated until UNLOCK TABLES.
That means when we release external lock and we're in LOCK TABLES,
we may write outdated state info.
As SQL layer closes all table instances, we do not need this
workaround anymore.

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.
Fixed by always logging a "downgraded" INSERT DELAYED: even
if there were no updates.

"Federated Denial of Service"
Federated storage engine used to attempt to open connections within
the ::create() and ::open() methods which are invoked while LOCK_open
mutex is being held by mysqld. As a result, no other client sessions
can open tables while Federated is attempting to open a connection.
Long DNS lookup times would stall mysqld's operation and a rogue
connection string which connects to a remote server which simply
stalls during handshake can stall mysqld for a much longer period of
time.
This patch moves the opening of the connection much later, when the
federated actually issues queries, by which time the LOCK_open mutex is
no longer being held.

The problem is that mysqldump generates incorrect dump for a table
with non-ASCII column name if the mysqldump's character set is
ASCII.
The fix is to:
1. Switch character_set_client for the mysqldump's connection
to binary before issuing SHOW CREATE TABLE statement in order
to avoid conversion.
2. Dump switch character_set_client statements to UTF8 and back
for CREATE TABLE statement.

Creating an EVENT to be executed at a time close to the end of the allowed
range (2038.01.19 03:14:07 UTC) would cause the server to crash. The
expected behavior is to accept all calendar times within the interval and
reject all other values without crashing.
This patch replaces the function 'sec_to_epoch_TIME' with a Time_zone API call.
This function was broken because it invoked the internal function 'sec_to_epoch'
without respecting the restrictions on the function parameters (and this caused
assertion failure). It also was used as a reverse function to
Time_zone_utc::gmt_sec_to_TIME which it isn't.

the inverse function of Time_zone_utc::gmt_sec_to_TIME() which was used

When the SQL_BIG_RESULT flag is specified SELECT should store items from the
select list in the filesort data and use them when sending to a client.
The get_addon_fields function is responsible for creating necessary structures
for that. But this function was allowed to do so only for SELECT and
INSERT .. SELECT queries. This makes the SQL_BIG_RESULT useless for
the CREATE .. SELECT queries.

This patch implements HA_STATUS_AUTO support in ha_federated::info()

usually the NO_AUTO_VALUE_ON_ZERO option of the
SQL_MODE variable was discarded.
This fix is for non-"--compact" mode of the mysqldump,
because mysqldump --compact never set SQL_MODE to the
value of NO_AUTO_VALUE_ON_ZERO.
The dump_triggers_for_table function has been modified
to restore previous value of the SQL_MODE variable after
dumping triggers using the SAVE_SQL_MODE temporary
variable.
