0 && next != 0' failed
close_connections() in mysqld.cc sends a signal to all threads.
But InnoDB is too busy purging, doesn't react immediately.
close_connections() waits 20 seconds, which isn't enough in this
particular case, and then unlinks all threads from
the list and forcibly closes their vio connection.
InnoDB background threads have no vio connection to close, but
they're unlinked all the same. So when later they finally notice
the shutdown request and try to unlink themselves, they fail to
assert that they're still linked.
Fix: don't assert_linked, as another thread can unlink this THD anytime

The bug occurs where the float token containing a dot with an 'e'
notation was dropped from the request completely.
This causes a manner of invalid SQL statements like:
select id 1.e, char 10.e(id 2.e), concat 3.e('a'12356.e,'b'1.e,'c'1.1234e)1.e, 12 1.e*2 1.e, 12 1.e/2 1.e, 12 1.e|2 1.e, 12 1.e^2 1.e, 12 1.e%2 1.e, 12 1.e&2 from test;
To be parsed correctly as if it was:
select id, char(id), concat('a','b','c'), 12*2, 12/2, 12|2, 12^2, 12%2, 12&2 from test.test;
This correct parsing occurs when e is followed by any of:
( ) . , | & % * ^ /

Currently, SST scripts assume that the filename specified in
the --log-bin-index argument either does not contain an extension
or uses the standard ".index" extension. Similar assumptions are
used for the log_bin_index parameter read from the configuration
file. This commit adds support for arbitrary extensions for the
index file paths.

If the server is started with the --innodb-force-recovery argument
on the command line, then during SST this argument can be passed to
mariabackup only at the --prepare stage, and accordingly it must be
removed from the --mysqld-args list (and it is not should be passed
to mariabackup otherwise).
This commit fixes a flaw in the SST scripts and add a test that
checks the ability to run the joiner node in a configuration that
uses --innodb-force-recovery=1.

statement
This bug led to reporting bogus messages "No database selected" for DELETE
statements if they used subqueries in their WHERE conditions and these
subqueries contained references to CTEs.
The bug happened because the grammar rule for DELETE statement did not
call the function LEX::check_cte_dependencies_and_resolve_references() and
as a result of it references to CTEs were not identified as such.

This bug concerned only CREATE TABLE statements of the form
CREATE TABLE <table name> AS <with clause> <union>.
For such a statement not all references to CTE used in <union> were resolved.
As a result a bogus message was reported for the first unresolved reference.
This happened because for such statements the function resolving references
to CTEs LEX::check_cte_dependencies_and_resolve_references() was called
prematurely in the parser.

This seems to be an old workaround for some upgrade warning, which did not
work for some time already, because the ini filename was not initialized.

to 'mariadb.sys'
From 10.4.13, the `mariadb.sys` user was created to replace `root` definers.
- In commit 0253ea7f2208354b187ffcfa2f3128878597cc11, definer of
Add/DropGeometryColumn procedures was changed to `mariadb.sys`, in
`scripts/maria_add_gis_sp.sql.in`.
However, maria_add_gis_sp.sql only applies to new databases created by
installation script. Databases upgraded from old versions will miss this
change.
- In addition, according to commit
0d6d801e5886208b2632247d88da106a543e1032(MDEV-23102), in some scenarios
when root user is replaced it will skip creating `mariadb.sys` user.
This commit is to update the definer from `root` to `mariadb.sys` during
upgrade. It only makes the change if the original definers are root.
Doesn't choose to execute `maria_add_gis_sp.sql` in upgrade script to
recreate the procedures is because of considering the scenarios of
MDEV-23102 that `root` user is replaced and `mariadb.sys` is not created.

This bug affected queries with two or more references to a CTE referring
another CTE if the definition of the latter contained an invocation of
a stored function that used a base table. The bug could lead to a bogus
error message or to an assertion failure.
For any non-first reference to CTE cte1 With_element::clone_parsed_spec()
is called that parses the specification of cte1 to construct the unit
structure for this usage of cte1. If cte1 refers to another CTE cte2
outside of the specification of cte1 then With_element::clone_parsed_spec()
has to be called for cte2 as well. This call is made by the function
LEX::resolve_references_to_cte() within the invocation of the function
With_element::clone_parsed_spec() for cte1.
When the specification of a CTE is parsed all table references encountered
in it must be added to the global list of table references for the query.
As the specification for the non-first usage of a CTE is parsed at a
recursive call of the parser the function With_element::clone_parsed_spec()
invoked at this recursive call should takes care of appending the list of
table references encountered in the specification of this CTE cte1 to the
list of table references created for the query. And it should do it after
the call of LEX::resolve_references_to_cte() that resolves references to
CTEs defined outside of the specification of cte1 because this call may
invoke the parser again for specifications of other CTEs and the table
references from their specifications must ultimately appear in the global
list of table references of the query.
The code of With_element::clone_parsed_spec() misplaced the call of
LEX::resolve_references_to_cte(). As a result LEX::query_tables_last used
for the query that was supposed to point to the field 'next_global' of the
last element in the global list of table references actually pointed to
'next_global' of the previous element.
The above inconsistency certainly caused serious problems when table
references used in the stored functions invoked in cloned specifications
of CTEs were added to the global list of table references.

MDEV-23805 simplified the treatment of empty tables during ALTER TABLE,
which could prevent the scenarios that were previously reported and
fixed as MDEV-16131 and MDEV-24730.
With the MDEV-23805 fix, the statement
SET DEBUG_SYNC = 'now WAIT_FOR copied';
could occasionally time out, depending on timing.
Apparently, there was a race condition where purge could resume
(and empty the table) before ALTER TABLE got the chance to execute.
We must prevent the purge of history from running before
ALTER TABLE has started executing.

- In ha_innobase::prepare_inplace_alter_table(), InnoDB should
check whether the table is empty. If the table is empty then
server should avoid downgrading the MDL after prepare phase.
It is more like instant alter, does change only in dicationary
and metadata.
- Changed few debug test case to make non-empty DDL table
