cf0c3ec274 MDEV-30307 KILL command inside a transaction causes problem for galera replication
Added new test scenario in galera.galera_bf_kill
test to make the issue surface. The tetst scenario has
a multi statement transaction containing a KILL command.
When the KILL is submitted, another transaction is
replicated, which causes BF abort for the KILL command
processing. Handling BF abort rollback while executing
KILL command causes node hanging, in this scenario.

sql_kill() and sql_kill_user() functions have now fix,
to perform implicit commit before starting the KILL command
execution. BEcause of the implicit commit, the KILL execution
will not happen inside transaction context anymore.

68938d2b42 MDEV-33500 (part 2): rpl.rpl_parallel_sbm can still fail
The failing test case validates Seconds_Behind_Master for a delayed
slave, while STOP SLAVE is executed during a delay. The test fixes
initially added to the test (commit b04c857596) added a table lock
to ensure a transaction could not finish before validating the
Seconds_Behind_Master field after SLAVE START, but did not address a
possibility that the transaction could finish before running the
STOP SLAVE command, which invalidates the validations for the rest
of the test case. Specifically, this would result in 1) a timeout in
“Waiting for table metadata lock” on the replica, which expects the
transaction to retry after slave restart and hit a lock conflict on
the locked tables (added in b04c857596), and 2) that
Seconds_Behind_Master should have increased, but did not.

The failure can be reproduced by synchronizing the slave to the master
before the MDEV-32265 echo statement (i.e. before the SLAVE STOP).

This patch fixes the test by adding a mechanism to use DEBUG_SYNC to
synchronize a MASTER_DELAY, rather than continually increase the
duration of the delay each time the test fails on buildbot. This is
to ensure that on slow machines, a delay does not pass before the
test gets a chance to validate results. Additionally, it decreases
overall test time because the test can continue immediately after
validation, thereby bypassing the remainder of a full delay for each
transaction.

024a18dbcb MDEV-34823 Invalid arguments in ib_push_warning()
In the bug report MDEV-32817 it occurred that the function
row_mysql_get_table_status() is outputting a fil_space_t*
as if it were a numeric tablespace identifier.

ib_push_warning(): Remove. Let us invoke push_warning_printf() directly.

innodb_decryption_failed(): Report a decryption failure and set the
dict_table_t::file_unreadable flag. This code was being duplicated in
very many places. We return the constant value DB_DECRYPTION_FAILED
in order to avoid code duplication in the callers and to allow tail calls.

innodb_fk_error(): Report a FOREIGN KEY error.

dict_foreign_def_get(), dict_foreign_def_get_fields(): Remove.
This code was being used in dict_create_add_foreign_to_dictionary()
in an apparently uncovered code path. That ib_push_warning() call
would pass the integer i+1 instead of a pointer to NUL terminated
string ("%s"), and therefore the call should have resulted in a crash.

dict_print_info_on_foreign_key_in_create_format(),
innobase_quote_identifier(): Add const qualifiers.

row_mysql_get_table_error(): Replaces row_mysql_get_table_status().

d1dc70675c MDEV-34864 SHOW INDEX FROM - SEQ_IN_INDEX to ULong
MySQL-Connector-Net casts SEQ_IN_INDEX to uint and will
raise an exception if the type is a System.Int64.

As we don't support a huge number of multi-columns in
an index reducing to a uint is sufficient to represent
all values and maintain compatibility with MySQL-Connector-Net.

This matches the type (uint) returned by MySQL-8.3 and 8.0.

235f33e360 MDEV-33133: MDL conflict handling code should skip BF-aborted trxs
It's possible that MDL conflict handling code is called more
than once for a transaction when:
- it holds more than one conflicting MDL lock
- reschedule_waiters() is executed,
which results in repeated attempts to BF-abort already aborted
transaction.
In such situations, it might be that BF-aborting logic sees
a partially rolled back transaction and erroneously decides
on future actions for such a transaction.

The specific situation tested and fixed is when a SR transaction
applied in the node gets BF-aborted by a started TOI operation.
It's then caught with the server transaction already rolled back,
but with no MDL locks yet released. This caused wrong state
detection for such a transaction during repeated MDL conflict
handling code execution.

731a5aba0b Use only MySQL code for TOI error vote
For TOI events specifically we have a situation where in case of the
same error different nodes may generate different messages. This may
be for two reasons:
 - different locale setting between the current client session and
   server default (we can reasonably require server locales to be
   identical on all nodes, but user can change message locale for the
   session)
 - non-deterministic course of STATEMENT execution e.g. for ALTER TABLE

On the other hand we may reasonably expect TOI event failures since
they are executed after replication, so we must ensure that voting is
consistent. For that purpose error codes should be sufficiently unique
and deterministic for TOI event failures as DDLs normally deal with
a single object, so we can merely use MySQL error codes to vote on.

Notice that this problem does not happen with regular transactional
writesets, since the originator node will always vote success and
replica nodes are assumed to have the same global locale setting.
As such different error messages indicate different errors even if
the error code is the same (e.g. ER_DUP_KEY can happen on different
rows tables).

Use only MySQL error code (without the error message) for error voting
in case of TOI event failure.

214e6c5b3d Fix sporadic failure of test case rpl.rpl_old_master
Remove the test for MDEV-14528. This is supposed to test that parallel
replication from pre-10.0 master will update Seconds_Behind_Master. But
after MDEV-12179 the SQL thread is blocked from even beginning to fetch
events from the relay log due to FLUSH TABLES WITH READ LOCK, so the test
case is no longer testing what is was intended to. And pre-10.0 versions are
long since out of support, so does not seem worthwhile to try to rewrite the
test to work another way.

The root cause of the test failure is MDEV-34778. Briefly, depending on
exact timing during slave stop, the rli->sql_thread_caught_up flag may end
up with different value. If it ends up as "true", this causes
Seconds_Behind_Master to be 0 during next slave start; and this caused test
case timeout as the test was waiting for Seconds_Behind_Master to become
non-zero.

- st_mysql_ftparser_boolean_info structure conveys boolean

25e2d0a6bb MDEV-34632 Assertion failed in handler::assert_icp_limitations
Assertion `table->field[0]->ptr >= table->record[0] &&
table->field[0]->ptr <= table->record[0] + table->s->reclength' failed in
handler::assert_icp_limitations.

table->move_fields has some limitations:
1. It cannot be used in cascade
2. It should always have a restoring pair.

Rule 1 is covered by assertions in handler::assert_icp_limitations
and handler::ptr_in_record (commit 30894fe9a9).

Rule 2 should be manually maintained with care. Hopefully, the rule 1 assertions
may sometimes help as well.

In ha_myisam::repair, both rules are broken. table->move_fields is used
asymmetrically there: it is set on every param->fix_record call
(i.e. in compute_vcols) but is restored only once, in the end of repair.

The reason to updating field ptr's for every call is that compute_vcols can
(supposedly) be called in parallel, that is, with the same table, but different
records.

The condition to "unmove" the pointers in ha_myisam::restore_vcos_after_repair
is incorrect, when stored vcols are available, and myisam stores a VIRTUAL field
if it's the only field in the table (the record cannot be of zero length).

This patch solves the problem by "unmoving" the pointers symmetrically, in
compute_vcols. That is, both rules will be preserved maintained.

b8f92ade57 MDEV-15393 gtid_slave_pos duplicate key errors after mysqldump restore
When mysqldump is run to dump the `mysql` system database, it generates
INSERT statements into the table `mysql.gtid_slave_pos`.
After running the backup script
those inserts did not produce the expected gtid state on slave. In
particular the maximum of mysql.gtid_slave_pos.sub_id did not make
into
   rpl_global_gtid_slave_state.last_sub_id

an in-memory object that is supposed to match the current state of the
table. And that was regardless of whether --gtid option was specified
or not. Later when the backup recipient server starts as slave
in *non-gtid* mode this desychronization may lead to a duplicate key
error.

This effect is corrected for --gtid mode mysqldump/mariadb-dump only
as the following.  The fixes ensure the insert block of the dump
script is followed with a "summing-up" SET @global.gtid_slave_pos
assignment.

For the implemenation part, note a deferred print-out of
SET-gtid_slave_pos and associated comments is prefered over relocating
of the entire blocks if (opt_master,slave_data &&
do_show_master,slave_status) ...  because of compatiblity
concern. Namely an error inside do_show_*() is handled in the new code
the same way, as early as, as before.

A regression test can be run in how-to-reproduce mode as well.
One affected mtr test observed.
rpl_mysqldump_slave.result "mismatch" shows now the new deferring print
of SET-gtid_slave_pos policy in action.

a061ae1079 MDEV-33921: Fix rpl_xa_empty_transaction.test
The test was missing a save_master_gtid.inc on the master,
leading to the slave thinking it was in sync after executing
sync_with_master_gtid.inc, despite not having executed the
latest transaction. This skipped transaction, XA COMMIT,
was supposed to error-to-be-ignored because its XID could not
be found, but be thrown out because the replication filters
would filter out the target database. However, if the slave
was able to stop before executing the transaction, then
the replication filer is reset (to empty), and when the
slave is later restarted, that transactions error would
no longer be ignored.

Additionally, as the test cases added in MDEV-33921 rely
on GTID synchronization, the test cases now force
master_use_gtid=slave_pos for consistency

incorrect value from frm, so eventual result is NULL.
2) 'Name_exp1' in column name (in gis.test)
This was because the identifier in SELECT is longer than 64 characters,
so 'Name_exp1' alias is also written to the view frm.
3)diff in explain extended
This was because the query plan for view protocol doesn't
contain database name. As a fix, disable view protocol for that particular
query.

00d2c7f7f4 MDEV-34542 Assertion `lock_trx_has_sys_table_locks(trx) == __null' failed in void row_mysql_unfreeze_data_dictionary(trx_t*)
- During XA PREPARE, InnoDB releases the non-exclusive locks.
But it fails to remove the non-exclusive table lock from the
transaction table locks. In the mean time, main thread evicts
the table from the LRU cache. While rollbacking the XA transaction,
InnoDB iterates through the table locks to check whether it
holds lock on any system tables and wrongly assumes the
evicted table as system table since the table id is 0

Fix:
===
During XA PREPARE, remove the table locks of the transaction while
releasing the non-exclusive locks.

Simplify in an attempt to avoid:

mysqltest: At line 275: File already exist: on the write_file
lines.

Using write_line as that's what a lot of other tests
do for writing small bits to a expect file.

Review thanks Valdislav Vaintroub
