sometimes `KILL QUERY ID @id` was executed before the previous

resets the kill status before execution, the effect of the KILL
was ignored.
Item_func_not_all::print() either uses Item_func::print() or
directly invokes args[0]->print(). Thus the precedence should be
either the one of Item_func or of args[0].
Item_allany_subselect::print() prints args[0], then a comparison op,
then a subquery. That is, the precedence should be the one of
a comparison.
rename to stress that is a specific hack for Item_func_nextval
and should not be used for other items.
If a vcol uses Item_func_nextval, a corresponding table for the sequence
should be added to the prelocking list (in that sense NEXTVAL is not
simply a function, but more like a subquery), see add_internal_tables()
in DML_prelocking_strategy::handle_table(). At the moment it is only
implemented for DEFAULT, not for GENERATED ALWAYS AS, thus the
VCOL_NEXTVAL hack.
select_union_direct::send_data() only sends a record when
the LIMIT ... OFFSET clause of the individual select won't skip it.
Thus, select_union_direct::send_data() should not do any actions
related to a sending a record if the offset of a select isn't
reached yet
Like in MDEV-16110 we must release items allocated on thd->mem_root by
reopening the table.
MDEV-16290 relocated MDEV-16110 fix in 10.5 so it works for MDEV-28576
as well. 10.3 without MDEV-16290 now duplicates this fix.
The change from MDEV-29465 exposed a flaw in replace_column_table
where again we were not properly updating the column-level bits.
replace_table_table was changed in MDEV-29465 to properly update
grant_table->init_cols, however replace_column_table still only
modified grant_column->rights when the GRANT_COLUMN already existed.
This lead to a missmatch between GRANT_COLUMN::init_rights and
GRANT_COLUMN::rights, *if* the GRANT_COLUMN already existed.
As an example:
GRANT SELECT (col1) ...
Here:
For col1
GRANT_COLUMN::init_rights and GRANT_COLUMN::rights are set to 1 (SELECT) in
replace_column_table.
GRANT INSERT (col1) ...
Here, without this patch GRANT_COLUMN::init_rights is still 1 and
GRANT_COLUMN::rights is 3 (SELECT_PRIV | INSERT_PRIV)
Finally, if before this patch, one does:
REVOKE SELECT (col1) ...
replace_table_table will see that init_rights loses bit 1 thus it
considers there are no more rights granted on that particular table.
This prompts the whole GRANT_TABLE to be removed via the first revoke,
when the GRANT_COLUMN corresponding to it should still have init_rights == 2.
By also updating replace_column_table to keep init_rights in sync
properly, the issue is resolved.

This commit contains only a mtr test for reproducing the issue in MDEV-29512
The actual fix will be pushed in wsrep-lib repository
The hanging in MDEV-29512 happens when binlog purging is attempted, and there is
one local BF aborted transaction waiting for commit monitor.
The test will launch two node cluster and enable binlogging with expire log days,
to force binlog purging to happen.
A local transaction is executed so that will become BF abort victim, and has advanced
to replication stage waiting for commit monitor for final cleanup (to mark position in innodb)
after that, applier is released to complete the BF abort and due to binlog configuration,
starting the binlog purging. This is where the hanging would occur, if code is buggy

Test MDEV-26575 fails when it runs after MDEV-25389. This is because
the latter simulates a failure while an applier thread is
created in `start_wsrep_THD()`. The failure was not handled correctly
and would not cleanup the created THD from the global
`server_threads`. A subsequent shutdown would hang and eventually fail
trying to close this THD.

MDEV-16735 describes how mysql_upgrade fails when alter_algorithm

regardless the global value of alter_altorithm, this commit force it's
value to 'DEFAULT' (note the quotes) for the mysql_upgrade session.

This is a DELETE only case. Normally this statement doesn't make inserts,
but DELETE ... FOR PORTION changes it. UPDATE and INSERT initializes
autoinc by calling handler::info(HA_STATUS_AUTO). Also myisam and innodb
can lazily initialize it in their update_create_info overrides.
The solution is to initialize autoinc during delete preparation,
if period (DELETE FOR PORTION) is specified.
The initial work has been done by Kento Takeuchi by his PR #2048,
however this commit also holds a few technical modifications by

Per fsp0types.h, SDI is on tablespace flags position 14 where MariaDB
stores its pagesize. Flag at position 13, also in MariaDB pagesize
flags, is a MySQL encryption flag.
These are checked only if fsp_flags_is_valid fails, so valid MariaDB
pages sizes don't become errors.
The error message "Cannot reset LSNs in table" was rather specific and
not always true to replaced with more generic error.

The issue is that record_should_be_deleted() returns true in
mysql_delete() even if sub-select with join gets error from storage
engine when DELETE FROM ... WHERE ... IN (SELECT ...) statement is
executed.
The same is true for mysql_update() where select->skip_record() returns
true even if sub-select with join gets error from storage engine.
In the test case if sub-select is chosen as deadlock victim the whole
transaction is rolled back during sub-select execution, but
mysql_delete()/mysql_update() continues transaction execution and invokes
table->delete_row() as record_should_be_deleted() wrongly returns true
in mysql_delete() and table->update_row() as select->skip_record(thd)
wrongly returns 1 for mysql_update().
record_should_be_deleted() wrogly returns true because thd->is_error()
returns false SQL_SELECT::skip_record() invoked from
record_should_be_deleted().
It's supposed that THD error should be set in rr_handle_error() called
from rr_sequential() during sub-select JOIN::exec_inner() execution.
But rr_handle_error() does not set THD error because
READ_RECORD::print_error is not set in JOIN_TAB::read_record.
READ_RECORD::print_error should be initialized in
init_read_record()/init_read_record_idx(). But make_join_readinfo() does
not invoke init_read_record()/init_read_record_idx() for
JOIN_TAB::read_record.
The fix is to set JOIN_TAB::read_record.print_error in
make_join_readinfo(), i.e. in the same place where
JOIN_TAB::read_record.table is set.

Problem:-
We are able to insert duplicate value in table because cmp_binary_offset
is not able to differentiate between NULL and empty string. So
check_duplicate_long_entry_key is never called and we don't check for
duplicate.
Solution
Added a if condition with is_null() on field which can differentiate
between NULL and empty string.
