Make all system tables in mysql directory of type
engine=Aria
Privilege tables are using transactional=1
Statistical tables are using transactional=0, to allow them
to be quickly updated with low overhead.
Help tables are also using transactional=0 as these are only
updated at init time.
Other changes:
- Aria store engine is now a required engine
- Update comment for Aria tables to reflect their new usage
- Fixed that _ma_reset_trn_for_table() removes unlocked table
from transaction table list. This was needed to allow one
to lock and unlock system tables separately from other
tables, for example when reading a procedure from mysql.proc
- Don't give a warning when using transactional=1 for engines
that is using transactions. This is both logical and also
to avoid warnings/errors when doing an alter of a privilege
table to InnoDB.
- Don't abort on warnings from ALTER TABLE for changes that
would be accepted by CREATE TABLE.
- New created Aria transactional tables are marked as not movable
(as they include create_rename_lsn).
- bootstrap.test was changed to kill orignal server, as one
can't anymore have two servers started at same time on same
data directory and data files.
- Disable maria.small_blocksize as one can't anymore change
aria block size after system tables are created.
- Speed up creation of help tables by using lock tables.
- wsrep_sst_resync now also copies Aria redo logs.
Intermediate commit.
Fix test failure in rpl.rpl_gtid_mdev4484 when an earlier test changed
the mysql.gtid_slave_pos table to innodb. With MDEV-12179, the delete
of the old GTID is skipped, because it is recorded as belonging to
another engine, due to ALTER TABLE in the test case.
Fix by restart the SQL thread after the ALTER to have the correct
engine registered.
Also fix the test case rpl.rpl_gtid_ignored to not leave
mysql.innodb_slave_pos as a different engine.
The ignored events are not written to the relay log, but instead a fake
Rotate event is generated to handle update of position.
Extend this for Gtid so we similarly generate a fake Gtid_list event
to update the GTID position.
Also fix an unrelated test issue that got triggered by the added test cases.
