In case a stored procedure is invoked in PS mode with argument of type ROW()
like the following one:
  CALL p1(ROW(10,20))
such statement fails with the error
  ER_OPERAND_COLUMNS (1241): Operand should contain 1 column(s)

The reason of emitting the error is that wrong method was invoked
on fixing an item corresponding to an argument of stored procedure -
the method fix_fields_if_needed_for_scalar() was called instead of
fix_fields_if_needed() that should be called.

fix it again, in 10.3, after a bad merge in 98e61598

- Proceed with commit fafb35ee

trans_rollback_to_savepoint(): Only release metadata locks (MDL)
if the storage engines agree, after the changes were already rolled back.

Ever since commit 3792693f
and mysql/mysql-server@55ceedbc3feb911505dcba6cee8080d55ce86dda
we used to cheat here and always release MDL if the binlog is disabled.

MDL are supposed to prevent race conditions between DML and DDL also
when no replication is in use. MDL are supposed to be a superset of
InnoDB table locks: InnoDB table lock may only exist if the thread
also holds MDL on the table name.

In the included test case, ROLLBACK TO SAVEPOINT would wrongly release
the MDL on both tables and let ALTER TABLE proceed, even though the DML
transaction is actually holding locks on the table.

Until commit 1bd681c8 (MDEV-25506)
in MariaDB 10.6, InnoDB would often work around the locking violation
in a blatantly non-ACID way: If locks exist on a table that is being
dropped (in this case, actually a partition of a table that is being
rebuilt by ALTER TABLE), InnoDB could move the table (or partition)
into a queue, to be dropped after the locks and references had been
released. If the lock is not released and the original copy of the
table not dropped quickly enough, a name conflict could occur on
a subsequent ALTER TABLE.

The scenario of commit 3792693f
is unaffected by this fix, because mysqldump
would use non-locking reads, and the transaction would not be holding
any InnoDB locks during the execution of ROLLBACK TO SAVEPOINT.
MVCC reads inside InnoDB are only covered by MDL and page latches,
not by any table or record locks.

FIXME: It would be nice if storage engines were specifically asked
which MDL can be released, instead of only offering a choice
between all or nothing. InnoDB should be able to release any
locks for tables that are no longer in trx_t::mod_tables, except
if another transaction had converted some implicit record locks
to explicit ones, before the ROLLBACK TO SAVEPOINT had been completed.

Fixup for commit 768c5188

A table rebuild that would truncate the default value of a
DATE column is expected to issue data truncation warnings.
But, these warnings are not being issued if the ADD COLUMN
is being executed with ALGORITHM=INSTANT. InnoDB sets the
warning of the field while assigning the default value
of the field during check_if_supported_inplace_alter().

Parital backport of 48938c57
so platform dependent AIX tests can be done.

Consider a query of the form:

  select ... from (select item2 as COL1) as T where COL1=123

Condition pushdown into derived table will try to push "COL1=123" condition
down into table T.
The process of pushdown involves "substituting" the item, that is,
replacing Item_field("T.COL1") with its "producing item" item2.
In order to use item2, one needs to clone it (call Item::build_clone).

If the item is not cloneable (e.g. Item_func_sp is not), the pushdown
process will fail and nothing at all will be pushed.

Fixed by introducing transform_condition_or_part() which will try to apply
the transformation for as many parts of condition as possible. The parts of
condition that couldn't be transformed are dropped.

Add KEYWORDS table and SQL_FUNCTIONS table to INFORMATION_SCHEMA.
This commits needs some minor changes when propagated upwards
(e.g. func_array in item_create.cc has a termination element that
 doesn't exist in later versions of MariaDB)

os_file_set_size(): Trim the current size down to the file system
block size, to obey the constraints for unbuffered I/O.

Handle invalid GEOJSON-s in Geometry::create_from_json().

If the first token of the body of a stored procedure was 'WITH' then
the beginning of the body was determined incorrectly and that token was
missing in the string representing the body of the SP in mysql.proc. As a
resultnany call of such procedure failed as the string representing the
body could not be parsed.

The patch corrects the code of the functions get_tok_start() and
get_cpp_tok_start() of the class Lex_input_stream to make them take into
account look ahead tokens. The patch is needed only for 10.2 as this
problem has neen resolved in 10.3+.

This bug affected queries with views / derived_tables / CTEs whose
specifications were of the form
  (SELECT ... LIMIT <n>) ORDER BY ...
Units representing such specifications contains one SELECT_LEX structure
for (SELECT ... LIMIT <n>) and additionally SELECT_LEX structure for
fake_select_lex. This fact should have been taken into account in the
function mysql_derived_fill().

This patch has to be applied to 10.2 and 10.3 only.
