table_already_fk_prelocked() was looking for a table in the wrong
list (not the complete list of prelocked tables, but only in its tail,
starting from the current table - which is always empty for the last
added table), so for circular FKs it kept adding same tables to the list
indefinitely.
Backport of d6d7e169fb
If a mtr test case has started two mysqld processes (replication tests),
then kills the first one and kills the second one before starting the
first (so at some point there are two mysqlds down), then the ./mtr
waiting process bricks and forgets to monitor the "expect" file of the
first mysqld, so it never gets started again, even when its contents is
changed to "restart".
A victim of this deficiency is at least galera.galera_gcache_recover.
The fix is to keep a list of all mysqlds we should wait to start, not
just one (the last one killed).

The problem was that join_columns creation was not finished due to error of notfound column in USING, but next execution tried to use join_columns lists.
Solution is cleanup the lists on error. It can eat memory in statement MEM_ROOT but it is an error and error will be fixed or statement/procedure removed/altered.
This regression was introduced in MDEV-16515.
We would fail to drop a temporary table on client disconnect,
because trx_is_interrupted() would hold. To add insult to
injury, in MariaDB 10.1, InnoDB temporary tables are actually
persistent, so the garbage temporary tables will never be dropped.
row_drop_table_for_mysql(): If several iterations of
buf_LRU_drop_page_hash_for_tablespace() are needed,
do not interrupt dropping a temporary table even after
the transaction was marked as killed.
Server shutdown will still terminate the loop, and also DROP TABLE
of persistent tables will keep checking if the execution was aborted.
Problem was that SQL level tried to read a record with rnd_pos()
that was already deleted by the same statement.
In the case where the page for the record had been deleted, this
caused an assert.
Fixed by extending the assert to also handle empty pages and
return HA_ERR_RECORD_DELETED for reads to deleted pages.
optimizer_use_condition_selectivity>=3
Selectivity analysis should be disabled for Geometrical columns
for the case like geometric_field= string_constant.
Currently for selectivity calculation we perform range analysis for a column even when we don't have any statistics(EITS).
This makes less sense but is used to catch contradiction for WHERE condition.
So the solution is to not perform range analysis for selectivity calculation for columns that do not have statistics.
Problem was that a parallel open of a table, overwrote info->state that
was in used by repair.
Fixed by changing _ma_tmp_disable_logging_for_table() to use
a new state buffer state.no_logging to store the temporary state.
Other things:
- Use original number of rows when retrying repair to get rid of a
potential warning "Number of rows changed from X to Y"
- Changed maria_commit() to make it easier to merge with 10.4
- If table is not locked (like with show commands), use the global
number of rows as the local number may not be up to date.
(Minor not critical fix)
- Added some missing DBUG_RETURN
Current versions of xtrabackup-v2 and mariabackup support the option
--innodb-data-home-dir, but this parameter is not passed to them from
the SST script, since the SST script does not receive this information
from mysqld. The transfer of this information to the SST is already
fixed by the MDEV-10754 patch, but we need to process it in the SST
script. Also, we should take into account that on the joiner side
the corresponding information is not read yet from the configuration
file (at the mysqld side) during the start of SST, so the script must
itself read it.

Problem was that Create_field::create_length_to_internal_length()
calculated a different pack_length for NEWDECIMAL compared to
Field_new_decimal constructor which lead to some unused bytes
in the middle of the record, which Aria didn't like.
Problem was that the number of NULL bit's was record wrong in the
.frm file because there could be more fields marked NOT_NULL after the
number of not_null fields where recorded.
Fixed by copying test for virtual fields from prepare_create_field()
The code change, only the test, doesn't have to be merged to 10.3
as this is fixed there.
and use_stat_tables= PREFERABLY
Currently the code that calculates selectivity for a table does not take into account the case when
we can have GROUP BY optimization (looses index scan).
trx_purge_add_update_undo_to_history(): Relax the too strict assertion
by removing the condition on srv_fast_shutdown (innodb_fast_shutdown).
Rollback is allowed during any form of shutdown.
buf_dump(): Only generate the output when shutdown is in progress.
log_write_up_to(): Only generate the output before actually writing
to the redo log files.
srv_purge_should_exit(): Rate-limit the output, and instead of
displaying the work done, indicate the work that remains to be done
until the completion of the slow shutdown.
