* removed universal suppression of everything "Event Schedule" everywhere
* added suppressions in tests as needed
* moved events test to the events suite
* renamed -master.opt -> .opt
* added standard test header
* verified in the test that the error, indeed, was written into the log
* removed useless suppressions
* removed ER_EVENTS_NO_ACL, replaced with ER_OPTION_PREVENTS_STATEMENT
* fixed error message to say exactly what option disabled event scheduler
instead of "this or that or that, you figure it out"
* also fixed old message for SET event_scheduler=
(it was also non-translatable)
* changed to use sql_print_error() when an error is not sent to the user
* removed duplicate hard-coded error message
Starting with commit da094188f6 (MDEV-24393),
MariaDB will no longer acquire advisory file locks on InnoDB data
files by default, because it would create a large number of
entries in Linux /proc/locks.
The motivation for acquiring the file locks is to prevent accidental
concurrent startup of multiple server processes on the same data files.
Such mistake still turns out to be relatively common, based on
corruption bug reports from the community.
To prevent corruption due to concurrent startup attempts, the
Aria storage engine would unconditionally acquire an advisory lock
on one of its log files.
Solution: InnoDB will always lock its system tablespace files.
(Ever since commit 685d958e38
the InnoDB log file will not necessarily be open while the
server is running, because it can be accessed via memory-mapped I/O.)
If more protection is desired, then the option --external-locking
can be used.
The mandatory advisory lock also fixes intermittent failures of
some crash recovery tests. It turns out that when the mtr test harness
kills and restarts the server, it will not actually ensure that the
old process has terminated before starting the new one.
The incorrect type of mysql.column_stats caused the server during the
upgrade of every other table to complain:
[ERROR] Incorrect definition of table mysql.column_stats: expected column 'hist_type' at position 9
and expected column 'histogram' at position 10 to have type longblob.
To prevent these verbose server errors, we upgrade the
mysql.column_stats table first.
Consequently limit "Incorrect definition of table mysql.*" to the appropriate
set of limited test cases.
The rpl_gtid_errorhandling.result changes the GTID number by one
because of the added early suppression (adding a table row).

for InnoDB tables"
Don't use thr_lock.c locks for InnoDB tables. Below is list of changes that
were needed to implement this:
- HANDLER OPEN acquireis MDL_SHARED_READ instead of MDL_SHARED
- HANDLER READ calls external_lock() even if SE is not going to be locked by
THR_LOCK
- InnoDB lock wait timeouts are now honored which are much shorter by default
than server lock wait timeouts (1 year vs 50 seconds)
- with @@autocommit= 1 LOCK TABLES disables autocommit implicitely, though
user still sees @@autocommt= 1
- the above starts implicit transaction
- transactions started by LOCK TABLES are now rolled back on disconnect
(previously everything was committed due to autocommit)
- transactions started by LOCK TABLES are now rolled back by ROLLBACK
(previously everything was committed due to autocommit)
- it is now impossible to change BINLOG_FORMAT under LOCK TABLES (at least
to statement) due to running transaction
- LOCK TABLES WRITE is additionally handled by MDL
- ...in contrast LOCK TABLES READ protection against DML is pure InnoDB
- combining transactional and non-transactional tables under LOCK TABLES
may cause rolled back changes in transactional table and "committed"
changes in non-transactional table
- user may disable innodb_table_locks, which will cause LOCK TABLES to be
noop basically
Removed tests for BUG#45143 and BUG#55930 which cover InnoDB + THR_LOCK. To
operate properly these tests require code flow to go through THR_LOCK debug
sync points, which is not the case after this patch. These tests are removed
by WL#6671 as well. An alternative is to port them to different storage engine.
Add some suppressions that were missing. They are for if a STOP SLAVE is
executed early during IO thread startup, when it is negotiating with the
master. The master connection may be killed in the middle of a
mysql_real_query(), which is not a test failure if it is a network error.
This also caught one real code error, fixed with this commit: The I/O thread
would fail to automatically reconnect if a network error happened while
fetching the value of @@GLOBAL.gtid_domain_id.
Merged lp:maria/maria-10.0-galera up to revision 3879.
Added a new functions to handler API to forcefully abort_transaction,
producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These
were added for future possiblity to add more storage engines that
could use galera replication.
4229: MDEV-5670: Assertion failure in file buf0lru.c line 2355
Add more status information if repeatable.
4230: MDEV-5673: Crash while parallel dropping multiple tables under heavy load
Improve long semaphore wait output to include all semaphore waits
and try to find out if there is a sequence of waiters.
4233: Fix compiler errors on product build.
4237: Fix too agressive long semaphore wait output and add guard against introducing
compression failures on insert buffer.
4238: Fix test failure caused by simulated compression failure on
IBUF_DUMMY table.
extend table names discovery (ha_discover_table_names() and Discovered_table_list) to return
or optionally filter out temporary tables ("#sql..."). SHOW commands and I_S tables
typically want temp table filtered out, while DROP DATABASE wants to see them too.
additonally, remove the supression for the warning "Invalid (old?) table or database name"
from mtr, and add it to .test files as needed (we need to test that this warning
does *not* happen in drop.test)
This makes it clear that the error code has nothing to do with errno.

Fixed suppression for new slave error messages
sql/rpl_reporting.cc:
Instead of writing "Errcode" to the log for Slave errors, use "Internal MariaDB error code"
Use post_kill_notification in for one_thread_per_connection scheduler,
the same as already used in threadpool, to reliably wake a thread stuck in
read() or in different poll() variations.
Add function to replace arbitrary event with dummy event.
Add code which uses this to fix the bug that enabling row_annotate events
on the master breaks slaves which do not request such events.
Add that slaves set a variable @mariadb_slave_capability to inform the
master in a robust way about which events it can, and cannot, handle.
Add tests.
