This is Kentoku's fix for MDEV-22979 (e6e41f04f4e + 22a0097727f),
which also fixes 30370. Adding a test for MDEV-29904 to avoid
regression, given MDEV-27233 is a similar problem.
Also update restart_spider.inc to allow passing restart_parameters, so
that the test of MDEV-29904 works (MDEV-27912).

Analysis:
When we skip level when path is found, it changes the state of the json
engine. This breaks the sequence for json_get_path_next() which is called at
the end to ensure json document is valid and leads to crash.
Fix:
Use json_scan_next() at the end to check if json document has correct
syntax (is valid).

MySQL 5.7.41 includes one InnoDB change
mysql/mysql-server@d2d6b2dd00f709bc528386009150d4bc726e25a0
that seems to be applicable to MariaDB Server 10.3 and 10.4.
Even though commit 5b9ee8d8193a8c7a8ebdd35eedcadc3ae78e7fc1
seems to have fixed sporadic failures on our CI systems, it is
theoretically possible that another race condition remained.
buf_flush_page_cleaner_coordinator(): In the final loop,
wait also for buf_get_n_pending_read_ios() to reach 0.
In this way, if a secondary index leaf page was read into the
buffer pool and ibuf_merge_or_delete_for_page() modified that
page or some change buffer pages, the flush loop would execute
until the buffer pool really is in a clean state.
This potential data corruption bug does not affect MariaDB Server 10.5
or later, thanks to commit b42294bc6409794bdbd2051b32fa079d81cea61d
which removed change buffer merges that are not explicitly requested.

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

Cluster conflict victim's THD is marked with wsrep_aborter.
THD::wsrep_aorter holds the thread ID of the hight priority tread,
which is currently carrying out BF aborting for this victim.
However, the BF abort operation is not always successful,
and in such case the wsrep_aborter mark should be removed.
In the old code, this wsrep_aborter resetting did not happen,
and this could lead to a situation where the sticky wsrep_aborter
mark prevents any further attempt to BF abort this transaction.
This commit fixes this issue, and resets wsrep_aborter after
unsuccesful BF abort attempt.

The problem was that federated engine does not support comparable rowids
which was not taken into account by semijoin code.
Fixed by checking that we don't use semijoin with tables that does not
support comparable rowids.

- Fixed some typos in the code comments

The reason things fails in 10.5 and above is that test_quick_select()
returns -1 (impossible range) for empty tables if there are any
conditions attached.
This didn't happen in 10.4 as the cost for a range was more than for
a table scan with 0 rows and get_key_scan_params() did not create any
range plans and thus did not mark the range as impossible.
The code that checked the 'impossible range' conditions did not take
into account all cases of LEFT JOIN usage.
Adding an extra check if the table is used with an ON condition in case
of 'impossible range' fixes the issue.

This commit changes backup execution (namely the block ddl phase),
so that node is not paused from cluster. Instead, the following
backup execution is declared as vulnerable for possible cluster
level conflicts, especially with DDL statement applying.
With this, the mariabackup execution may be aborted, if DDL
statements happen during backup execution. This abortable
backup execution is optional feature and may be
enabled/disabled by wsrep_mode: BF_ABORT_MARIABACKUP.
Note that old style node desync and pause, despite of
WSREP_MODE_BF_MARIABACKUP is needed if node is operating as
SST donor.

node->is_delete was incorrectly set to NO_DELETE for a set of operations.
In general we shouldn't rely on sql_command and look for more abstract ways
to control the behavior.
trg_event_map seems to be a suitable way. To mind replica nodes, it is ORed
with slave_fk_event_map, which stores trg_event_map when replica has
triggers disabled.

columns: Don't know how to handle column type: 140
Problem:
=======
Mysqlbinlog cannot show the type of a compressed
column when two levels of verbosity is provided.
Solution:
========
Extend the log event printing logic to handle and
tag compressed types.
Behavioral Changes:
==================
Old: When mysqlbinlog is called in verbose mode and
the database uses compressed columns, an error is
returned to the user.
New: The output will append “ COMPRESSED” on the
type of compressed columns

This commit adds support for the --aria-log-dir-path
option on the command line and for the aria-log-dir-path
option in the configuration file to the SST scripts, since
before this change these parameters were completely ignored
during SST - SST scripts assumed that aria logs files are
always located in the same directory as logs for innodb.
Tests for this change will be added as a separate commit,
along with tests for MDEV-30157 and MDEV-28669.

This commit adds even more correct handling of parameters
with paths when they contain leading or trailing spaces and/or
slashes. Also it fixes problems that occur when the user specified
explicit paths to additional directories, but these paths match
the specified path of the data directory - in this case, additional
subdirectories should be treated (in relation to the data directory)
in the same way as if these paths were not specified or as if they
are implicitly specified as "." or "./". But prior to this fix,
existing code treated any values as if they were completely
separate directories, whether or not they actually point to the
same location to which datadir points to - and this sometimes
resulted in incorrect file transfers.
This fix does not contain separate tests, as tests will be
part of the main commit(s). This fix has been made as a separate
commit to facilitate review for major substantive fixes related
to MDEV-30157 and MDEV-28669.

(Variant 3, initial variant was by Rex Jonston)
A LEFT JOIN with a constant as a column of the inner table produced wrong
query result if the optimizer had to write the inner table column into a
temp table. Query pattern:
SELECT ...
FROM (SELECT /*non-mergeable select*/
FROM t1 LEFT JOIN (SELECT 'Y' as Val) t2 ON ...) as tbl
Fixed this by adding Item_direct_view_ref::save_in_field() which follows
the pattern of Item_direct_view_ref's save_org_in_field(),
save_in_result_field() and val_XXX() functions:
* call check_null_ref() and handle NULL value
* if we didn't get a NULL-complemented row, call Item_direct_ref's function.

clang15 finally errors on old prototype definations.
Its also a lot fussier about variables that aren't used
as is the case a number of time with loop counters that
aren't examined.
RocksDB was complaining that its get_range function was
declared without the array length in ha_rocksdb.h. While
a constant is used rather than trying to import the
Rdb_key_def::INDEX_NUMBER_SIZE header (was causing a lot of
errors on the defination of other orders). If the constant
does change can be assured that the same compile warnings will
tell us of the error.
The ha_rocksdb::index_read_map_impl DBUG_EXECUTE_IF was similar
to the existing endless functions used in replication tests.
Its rather moot point as the rocksdb.force_shutdown test that
uses myrocks_busy_loop_on_row_read is currently disabled.
