to copy datafile

- Mariabackup fails to copy the undo log tablespace when it undergoes
truncation. So Mariabackup should detect the redo log which does
undo tablespace truncation and also backup should read the minimum
file size of the tablespace and ignore the error while reading.

- Throw error when innodb undo tablespace read failed, but backup
doesn't find the redo log for undo tablespace truncation

Since 7c58e97b the PSI_memory_key was added to some routines in the

MDEV-30325 Wrong result upon range query using index condition wrong result upon range query using index condition

This was caused by a bug in key_or() when SEL_ARG* key1 has been cloned
and is overlapping with SEL_ARG *key2

Cloning of SEL_ARG's happens only in very special cases, which is why this
bug has remained undetected for years.

It happend in the following query:

SELECT COUNT(*) FROM lineitem force index
(i_l_orderkey_quantity,i_l_shipdate) WHERE
l_shipdate < '1994-01-01' AND l_orderkey < 800 OR
l_quantity > 3 AND l_orderkey NOT IN ( 157, 1444 );

Because there are two different indexes that can be used and the code for
IN causes a 'tree_or', which causes all SEL_ARG's to be cloned.

Other things:
- While checking the code, I found a bug in SEL_ARG::SEL_ARG(SEL_ARG &arg)
 - This was incrementing next_key_part->use_count as part of creating a
   copy of an existing SEL_ARG.
   This is however not enough as the 'reverse operation' when the copy is
   not needed is 'key2_cpy.increment_use_count(-1)', which does something
   completely different.
   Fixed by calling increment_use_count(1) in SEL_ARG::SEL_ARG.

- Returns DB_LOCK_WAIT_TIMEOUT for the stats_lock_fail

When building with -DWITH_WSREP=OFF, files required for MTR tests are
excluded and several tests fail. This is cause by a recent commit
7b44d0ba which attempted to resolve MDEV-23230.

Even when building without WSREP/Galera support some of the MTR include
files named *wsrep* are required by other tests.

Removing the following from the CMake install macros will avoid
excluding the MTR test .inc files:
`|include/((w.*)?wsrep.*|.*galera.*)\\.inc`

The problem was that when storing rows into a temporary table,
MIN/MAX items that where marked as constants (as theire value had
been computed at start of query) would be reset.

Fixed by not reseting MIN/MAX items that are marked as const in
Item_sum_min_max::clear().

custom code in `case OPT_SKIP_RESOLVE`
was overriding the correct value from handle_options().

covers `git commit -a` and `git citool` (`git add`, `git status`, etc).
they can still be added explicitly

the parser couldn't parse `1=2 not between 3 and 5`
after `2` it expected only NOT2_SYM, but not NOT_SYM
(visible from the sql_yacc.output file), which resulted in
Syntax error ... near 'not between 3 and 4'

The parser was confused by a rather low NOT_SYM precedence and
%prec BETWEEN_SYM didn't resolve this confusion.

As a fix, let's remove any %precedence from NOT_SYM and
specify %prec explicitly in the only place where it matters for NOT_SYM.

In other places, such as for NOT BETWEEN, NOT_SYM won't have a
precedence, so bison won't be confused about it.

Without Galera, mariabackup should ignore the --galera-info option
and not fail with rc != 0 like it does now. This commit fixes this flaw.

1. In case of system-versioned table add row_end into FTS_DOC_ID index
   in fts_create_common_tables() and innobase_create_key_defs().
   fts_n_uniq() returns 1 or 2 depending on whether the table is
   system-versioned.

   After this patch recreate of FTS_DOC_ID index is required for
   existing system-versioned tables. If you see this message in error
   log or server warnings: "InnoDB: Table db/t1 contains 2 indexes
   inside InnoDB, which is different from the number of indexes 1
   defined in the MariaDB" use this command to fix the table:

      ALTER TABLE db.t1 FORCE;

2. Fix duplicate history for secondary unique index like it was done
   in MDEV-23644 for clustered index (932ec586). In case of
   existing history row which conflicts with currently inseted row we
   check in row_ins_scan_sec_index_for_duplicate() whether that row
   was inserted as part of current transaction. In that case we
   indicate with DB_FOREIGN_DUPLICATE_KEY that new history row is not
   needed and should be silently skipped.

3. Some parts of MDEV-21138 (7410ff43) reverted. Skipping of
   FTS_DOC_ID index for history rows made problems with purge
   system. Now this is fixed differently by p.2.

4. wait_all_purged.inc checks that we didn't affect non-history rows
   so they are deleted and purged correctly.

Additional FTS fixes

  fts_init_get_doc_id(): exclude history rows from max_doc_id
  calculation. fts_init_get_doc_id() callback is used only for crash
  recovery.

  fts_add_doc_by_id(): set max value for row_end field.

  fts_read_stopword(): stopwords table can be system-versioned too. We
  now read stopwords only for current data.

  row_insert_for_mysql(): exclude history rows from doc_id validation.

  row_merge_read_clustered_index(): exclude history_rows from doc_id
  processing.

  fts_load_user_stopword(): for versioned table retrieve row_end field
  and skip history rows. For non-versioned table we retrieve 'value'
  field twice (just for uniformity).

FTS tests for System Versioning now include maybe_versioning.inc which
adds 3 combinations:

'vers'     for debug build sets sysvers_force and
	   sysvers_hide. sysvers_force makes every created table
	   system-versioned, sysvers_hide hides WITH SYSTEM VERSIONING
	   for SHOW CREATE.

	   Note: basic.test, stopword.test and versioning.test do not
	   require debug for 'vers' combination. This is controlled by
	   $modify_create_table in maybe_versioning.inc and these
	   tests run WITH SYSTEM VERSIONING explicitly which allows to
	   test 'vers' combination on non-debug builds.

'vers_trx' like 'vers' sets sysvers_force_trx and sysvers_hide. That
	   tests FTS with trx_id-based System Versioning.

'orig' 	   works like before: no System Versioning is added, no debug is
	   required.

Upgrade/downgrade test for System Versioning is done by
innodb_fts.versioning. It has 2 combinations:

'prepare' makes binaries in std_data (requires old server and OLD_BINDIR).
	  It tests upgrade/downgrade against old server as well.

'upgrade' tests upgrade against binaries in std_data.

Cleanups:

Removed innodb-fts-stopword.test as it duplicates stopword.test

Adds new parameter $restart_bindir for restart_mysqld.inc.

Example:

let $restart_bindir= /home/midenok/src/mariadb/10.3b/build;
--source include/restart_mysqld.inc

It is good to return back original server before check_mysqld will be
run at the test end:

let $restart_bindir=;
--source include/restart_mysqld.inc

Works like vers_force but forces trx_id-based system-versioned tables
if the storage supports it (currently InnoDB-only). Otherwise creates
timestamp-based system-versioned table.

ha_spider::create(): Pass the correct length of the argument of the
CHARSET attribute. The macro STRING_WITH_LEN() is intended to be used
with NUL terminated string constants only. Here, it would incorrectly
pass sizeof(char*)-1 as the length.

The incorrect type handler caused an incorrect result_type() for
Item_cache_row (STRING_RESULT rather than ROW_RESULT). By updating the
constructor of Item_cache_row with the correct type handler, it fixes
this problem.

simply using latest package versions, as is works and is likely to work
best in the long run.

Also, enclose "../rpmlist-$CI_JOB_NAME-$CI_COMMIT_REF_SLUG.log" in

Additionally use "needs" statements to allow tests to run immediately

Before the fix next-key lock was requested only if a record was
delete-marked for locking unique search in RR isolation level.
There can be several delete-marked records for the same unique key,
that's why InnoDB scans the records until eighter non-delete-marked record
is reached or all delete-marked records with the same unique key are
scanned.

For range scan next-key locks are used for RR to protect scanned range from
inserting new records by other transactions. And this is the reason of why
next-key locks are used for delete-marked records for unique searches.

If a record is not delete-marked, the requested lock type was "not-gap".
When a record is not delete-marked during lock request by trx 1, and
some other transaction holds conflicting lock, trx 1 creates waiting
not-gap lock on the record and suspends. During trx 1 suspending the
record can be delete-marked. And when the lock is granted on conflicting
transaction commit or rollback, its type is still "not-gap". So we have
"not-gap" lock on delete-marked record for RR. And this let some other
transaction to insert some record with the same unique key when trx 1 is
not committed, what can cause isolation level violation.

The fix is to set next-key locks for both delete-marked and
non-delete-marked records for unique search in RR.
