Package mariadb-test-data has test files
in directory '/usr/share/mysql/mysql-test/' which are not UTF-8
encoded and they should not be as they are for testing.

package also have Lintian warnings for files that
are not in correct place in directory 'usr/share/mysql/mysql-test'
but as they are all are test results they are not in incorrect place

At last there is intentional use for some repeated directories so
they are false-positives and should be suspended

Cause: a copy of the joined TABLE_LIST is created during multi_update::prepare
and TABLE::pos_in_table_list of the tables are set to point to the new
TABLE_LIST object. This prevents some optimization steps to perform correctly.
Solution: do not update pos_in_table_list during multi_update::prepare

MDEV-14642 Assertion 'table->s->db_create_options == part_table->s->db_create_options' failed in compare_table_with_partition

When trying to execute ALTER TABLE EXCHANGE PARTITION with different
definitions, assertion

    table->s->db_create_options == part_table->s->db_create_options

failed in compare_table_with_partition().

However, this execution should not be allowed since executing
'exchange partition' requires the identical structure of the two tables.

To fix the problem, I deleted the assertion code and added code that
returns an error that indicates tables have different definitions.

that is not in binlog.

Post-crash recovery of --rpl-semi-sync-slave-enabled server
failed to recognize a transaction in-doubt that needed rolled back.
A prepared-but-not-in-binlog transaction gets committed instead
to possibly create inconsistency with a master (e.g the way it was observed
in the bug report).

The semisync recovery is corrected now with initializing binlog coordinates
of any transaction in-doubt to the maximum offset which is
unreachable.
In effect when a prepared transaction that is not found in binlog
it will be decided to rollback because it's guaranteed to reside
in a truncated tail area of binlog.

Mtr tests are reinforced to cover the described scenario.

commit 84984b79 is null-merged

This commit sends a flag indicating the presence of the "--bypass"
option from the donor node to the joiner nodes during rsync IST,
because without such a flag it is impossible to distinguish IST
from the SST on the joiner nodes (in IST/SST scripts, because the
"--bypass" option is still not passed to scripts from server code).
Specifically, this fixes an issue with binary logs disappearing
after IST (via rsync). There are also changes to diagnostic messages
here that will make it easier to diagnose script-related problems
in the future when debugging and when checking the logs. This commit
also adds more robust signal handlers - to handle exceptions during
script execution. These handlers won't mask some crashes and it
also unifies exit codes between different scripts. These changes
have already been helpful to debugging "bypass" flag handling.

This commit fixes an issue with IST handling in
version 10.9 which is a regression after MDEV-26971
and related to trying to get a non-existent "total"
tag on the IST branch (this tag is only defined in
SST mode).

We cannot permanently change bits in read_partitions in the middle of
processing because ha_rnd_init()/ha_rnd_end() depends on that.

prefer if/skip over require
(works better with debugging, not affected by query log)

This reverts commit 17e0f522.

Function wsrep_read_only_option was already removed in commit
d54bc3c0 because it could cause race condition on variable
opt_readonly so that value OFF can become permanent.
Removed function again and added test case. Note that writes
to TEMPORARY tables are still allowed when read_only=ON.

same as MDEV-26412, but in CREATE...SELECT.
fix: apply 39feab3c to create rule too.

The counter srv_stats.key_rotation_list_length is never updated, and
therefore Innodb_encryption_key_rotation_list_length will always be 0.

The view INFORMATION_SCHEMA.INNODB_TABLESPACES_ENCRYPTION comes close
to reporting this information.

The counters were added in commit 5e55d1ce
and any code to update them was
inadvertently removed in commit 2e814d47
when applying InnoDB changes from MySQL 5.7.

Let us remove these counters that never reported anything useful. If such
statistics are really needed in a special case, they can be obtained by
instrumenting the code by some means, such as eBPF or a source code patch.

This patch fixes a problem that arises when a Galera node acts as a
replica for native replication. When parallel applying is enabled, it
is possible to end up with attempts to write binlog events with gtids
out of order. This happens because when multiple events are delivered
from the native replication stream and applied in concurrently, it is
for them to be replicated to the Galera cluster in an order which is
different from the original order in which they were committed in the
aync replication master.
To correct this behavior we now wait_for_prior_commit() before
replicating changes though galera. As a consequence, parallel appliers
may apply events in parallel until the galera replication step, which
is now serialized.

Add disconnect.

Decrease the number of tables and operations.

Arythmetic can overrun the uint type when possible group_concat_max_len
is multiplied to collation.mbmaxlen (can easily be like 4).
So use ulonglong there for calculations.

The warning comes from copying POSITION objects where 'type' is not
initialized.  This does not affect any production code as when 'type'
was compared/used, it was always initialized.

Removed by initializing the type variable in the constructor

- In best_extension_by_limited_search(), do not check for
  "(remaining_tables & real_table_bit)", it is guaranteed to be true.
  Make it an assert.
- In (!idx || check_interleaving_with_nj())", remove the !idx part.
  This check made sense only in the original version of this function.
- "micro optimization" in check_interleaving_with_nj().
