* Total order isolation was started twice for FLUSH TABLES, from
reload_acl_and_cache() and from mysql_execute_command(). Removed
the reload_acl_and_cache() part.
* Removed PXC specific stuff from MTR tests
- Eliminates code duplication in query cache patch
- Reduces the number of iterations in mysql-wsrep#201.test
to shorten the execution time
- Adds a new test case that exercises more scenarios
The admin commands in question are:
> OPTIMIZE
> REPAIR
> ANALYZE
For LOCAL or NO_WRITE_TO_BINLOG invocations of these commands, ie
OPTIMIZE LOCAL TABLE <t1>
they are not binlogged as expected.
Also, in addition, they are not executed under TOI.
Hence, they are not propagated to other nodes.
The effect is same as that of wsrep_on=0.
Also added tests for this.
A WSREP_DEBUG for wsrep_register_hton has also been added.
The galera_flush_local test has also been updated for verifying that effects
of NO_WRITE_TO_BINLOG / LOCAL are equivalent to wsrep_on=0 from wsrep
perspective.

- Fixes query cache so that it is aware of wsrep_sync_wait.
Query cache would return (possibly stale) results to the
client, regardless of the value of wsrep_sync_wait.
- Includes the test case that reproduced the issue.
- Removes useless call to wsrep_xid_init() in wsrep_apply_events().
Transaction's xid is already initialized at that point.
- Adds call to wsrep_set_SE_checkpoint() for committing TOI events
in the applier side.
- Includes test case that reproduced the issue.
- Moves call wsrep_free_status() to THD::cleanup_after_query().
Wsrep status variables were previously freed only on SHOW STATUS.
- Removes valgrind suppression from mysql-test/valgrind.
of mdev-8789.
Fixed a bug in TABLE_LIST::print.
Fixed another bug for the case when the definition of a
WITH table contained column list while the join in the main
query used two instances of this table.
- Add temporary code: clone_read_record() clones READ_RECORD structure,
as long as it is used for reading filesort() result that fits into
memory.
- Add frame bounds for ROWS-type frames. ROWS n PRECEDING|FOLLOWING,
ROWS UNBOUNDED PRECEDING|FOLLOWING, CURRENT ROW are supported.
- Add Item_sum_count::remove() which allows "streaming" computation
of COUNT() over a moving frame.
There was two problems. Firstly, if page in ibuf is encrypted but
decrypt failed we should not allow InnoDB to start because
this means that system tablespace is encrypted and not usable.
Secondly, if page decrypt is detected we should return false
from buf_page_decrypt_after_read.

Federated/spider/connect engines or replication threads connecting to other host
with empty user name may crash mysqld.
This is addition to original patch, which adds a test case and amends a macro.
MDEV-9469: 'Incorrect key file' on ALTER TABLE
InnoDB needs to rebuild table if column name is changed and
added index (or foreign key) is created based on this new
name in same alter table.
Fix the doubly questional fix for MySQL Bug#17250787:
* it detected autoinc index by looking for the first index
that starts from autoinc column. never mind one column
can be part of many indexes.
* it used autoinc_field->field_index to look up into internal
innodb dictionary. But field_index accounts for virtual
columns too, while innodb dictionary ignores them.
Find the index by its name, like elsewhere in ha_innobase.
