For the grant_plugin/innodb_fts.fulltext changed
the tests to use a temporary table rather than a
user variable.
MDEV-35350 consolidated two methods that MTR tests
would wait until a file had certain content
written to it, which were only available in 10.6+.
This patch only backports the functionality to
10.5 in case some test wants to use it (nothing
uses it in 10.5 at present).
The cleanup bc46f1a7d9 from 10.6 is also
backported so SEARCH_TYPE doesn't need to be
accounted for in the new search_pattern_in_file.inc
logic.
- Replace statement fails with duplicate key error when multiple
unique key conflict happens. Reason is that Server expects the
InnoDB engine to store the confliciting keys in ascending order.
But the InnoDB doesn't store the conflicting keys
in ascending order.
Fix:

- Enable HA_DUPLICATE_KEY_NOT_IN_ORDER for InnoDB storage engine
only when unique index order is different in .frm and innodb dictionary.

- dict_stats_table_clone_create() does not initialize the
flag stats_error_printed in either dict_table_t or dict_index_t.
Because dict_stats_save_index_stat() is operating on a copy
of a dict_index_t object, it appears that
dict_index_t::stats_error_printed will always be false
for actual metadata objects, and uninitialized in
dict_stats_save_index_stat().
Solution:
=========
dict_stats_table_clone_create(): Assign stats_error_printed
for table and index while copying the statistics

While applying CTAS log event, we peek the relay log to see if CTAS
contains inserted rows or if it's empty.
The peek function didn't check for end-of-file condition when tried to
get the next event from the log, and thus it hanged.
The fix includes checking for end-of-file while peeking for log events
and considering returned XID_EVENT value as a sign of an empty CTAS.

Post-fix for MDEV-35144.
Cannot allocate options values on the statement arena, because
HA_CREATE_INFO is shallow-copied for every execution, so if the
option_list was initially empty, it will be reset for every execution
and any values allocated on the statement arena will be lost.
Cannot allocate option values on the execution arena, because
HA_CREATE_INFO is shallow-copied for every execution, so if the

- InnoDB fulltext rebuilds the FTS COMMON table while adding the

When adding a column or index that uses plugin-defined
sysvar-based options with CREATE ... LIKE the server
was using the current value of the sysvar, not the default one.
Because parse_option_list() function was used both in create
and open and it tried to guess when it's create (need to use
current sysvar value and add a new name=value pair to the list)
or open (need to use default, without extending the list).
Let's move the list extending functionality into a separate
function and call it explicitly when needed. Operations that
add new objects (CREATE, ALTER ... ADD) will extend the list,
other operations (ALTER, CREATE ... LIKE, open) will not.
Remove workaround for MDEV-13941, it served for 5 years,and all affected

Apparently Innodb is using is_sparse parameter in os_file_set_size()

extension. With MDEV-13941 workaround in place, it would unsparse
the file, which is makes compression not to work at all anymore.

Problem:

- Redundant table fails to insert into the table after
instant drop blob column. Instant drop column only marking
the column as hidden and consecutive insert statement tries
to insert NULL value for the dropped BLOB column and returns
the fixed length of the blob type as 65535. This lead to
row size too large error.
Fix:

For redundant table, if the non-fixed dropped column can be null
then set the length of the field type as 0.

Sometimes, in MariaDB Server 10.5 but apparently not in later branches,
the test would hang because con1 and con2 would be blocked in
debug_sync (for example, lock_wait_suspend_thread_enter and
row_ins_sec_index_entry_dup_locks_created) and therefore blocking
the purge of transactions from completing.
To prevent an occasional DEBUG_SYNC induced hang in the test, we will
wait for everything to be purged, except the last 2 transactions.
This change should be null-merged to 10.6, because the test is not
failing in 10.6 or later major versions.
Hash index is vcol-based wrapper (MDEV-371). row_end is added to
unique index. So when row_end is updated unique hash index must be
recalculated via vcol_update_fields(). DELETE did not update virtual
fields, so DELETE HISTORY was getting wrong hash value.
The fix does update_virtual_fields() on vers_update_end() so in every
case row_end is updated virtual fields are updated as well.
work consistently on replication
Row-based replication does not execute CREATE .. SELECT but instead
CREATE TABLE. CREATE .. SELECT creates implict system fields on
unusual place: in-between declared fields and select fields. That was
done because select_field_pos logic requires select fields go last in
create_list.
So, CREATE .. SELECT on master and CREATE TABLE on slave create system
fields on different positions and replication gets field mismatch.
To fix this we've changed CREATE .. SELECT to create implicit system
fields on usual place in the end and updated select_field_pos for
handling this case.
When calculate_cond_selectivity_for_table() takes into account multi-
column selectivities from range access, it tries to take-into account
that selectivity for some columns may have been already taken into account.
For example, for range access on IDX1 using {kp1, kp2}, the selectivity
of restrictions on "kp2" might have already been taken into account
to some extent.
So, the code tries to "discount" that using rec_per_key[] estimates.
This seems to be wrong and unreliable: the "discounting" may produce a
rselectivity_multiplier number that hints that the overall selectivity
of range access on IDX1 was greater than 1.
Do a conservative fix: if we arrive at conclusion that selectivity of
range access on condition in IDX1 >1.0, clip it down to 1.

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.

Updated tests: cases with bugs or which cannot be run

Fix for v.10.5
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.

This code was being used in dict_create_add_foreign_to_dictionary()

MySQL-Connector-Net casts SEQ_IN_INDEX to uint and will

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.

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.
