optimize_semi_joins() calls update_sj_state() to update semi-join
optimization state in the JOIN class.

greedy_search() algorithm considers different join prefixes,
and then picks one table to put into the join prefix.
Most of the semi-join optimization state is in the table's entry
in the join->positions[cur_prefix_size].

However, it also needs to call update_sj_state() to update the
semi-join optimization state in the JOIN class.

There is one exception, which is the cause of this bug: when we're
inside optimize_semi_join_nests() and are optimizing a subquery,
optimize_semi_joins() does nothing, it doesn't call update_sj_state().

greedy_search() must not do that either.

Add check for path length if CreateFile fails with ERROR_PATH_NOT_FOUND.

This problem was earlier fixed by the patch for MDEV-21445.

MDEV-26544 Assertion `part_share->auto_inc_initialized' failed in ha_partition::get_auto_increment on INSERT

The partition storage engine ignores return (error) values of
handler::info(). As a result, a query that should be aborted is
not aborted and then the server violates the assertion.

Item_func_xor and Item_cond are both derived class of Item_bool_func.
Spider converts *Item_func_xor to *Item_cond and then calls the member
function argument_list(), which Item_func_xor does not implement.

The convention used for options in mtr are 2 underscores
Prior to this patch, the "parallel" option used only one underscore

- InnoDB mistakenly identifies the non-unique FTS_DOC_ID index as
FTS_DOC_ID_INDEX while loading the table. dict_load_indexes()
should check whether the index is unique before assigning
fts_doc_id_index

Before version 10, GCC would think that a right shift of an
unsigned char returns int. Let us explicitly cast that back,
to silence a bogus -Wconversion warning.

Also, refactor trx_i_s_common_fill_table() to remove dead code.

Warnings about yynerrs in Bison-generated yyparse() will remain for now.

K&R style function definitions are deprecated in all versions of C

- Redundant InnoDB table fails to set the flags2 while loading
the table. It leads to "Upgrade index name failure" during alter

MDEV-21310 AUTO_INCREMENT column throws range error on INSERT in partitioned table | Assertion `part_share->auto_inc_initialized || !can_use_for_auto_inc_init()' failed.

The bug is caused by a similar mechanism as MDEV-21027.

The function, check_insert_or_replace_autoincrement, failed to open
all the partitions on INSERT SELECT statements and it results in the
assertion error.

prepare_inplace_alter_table_dict(): If the table will not be rebuilt,
preserve all of the original ROW_FORMAT, including the compressed
page size flags related to ROW_FORMAT=COMPRESSED.

hex_to_ascii(): Add #if around the definition to avoid
clang -Wunused-function. Avoid GCC 5 -Wconversion with a cast.

buf_page_print(): Dump the buffer page 32 bytes (64 hexadecimal digits)
per line. In this way, the limitation in mtr
("Data too long for column 'line'") will not be triggered.

Also, do not bother decoding the page contents, because everything
is present in the hexadecimal output.

dict_index_find_on_id_low(): Merge to dict_index_get_if_in_cache_low().
The direct call in buf_page_print() was prone to crashing, in case the
table definition was concurrently evicted or dropped from the
data dictionary cache.

Spider supports (or at least allows) INSERT DELAYED but the
documentation does not specify spider as a storage engine that supports
"INSERT DELAYED".
Also, although not mentioned in the documentation, "INSERT DELAYED" is
not intended to be executed inside a transaction, as can be seen from
the list of supported storage engines.
The current implementation allows executing a delayed insert on a
remote transactional table and this breaks the consistency ensured by
the transaction.

We too remove "internal_delayed", one of the Spider table parameters.
Documentation says,

> Whether to transmit existence of delay to remote servers when
> executing an INSERT DELAYED statement on local server.

This table parameter is only used for "INSERT DELAYED".

This commit contains workaround for a bug known as 'Red Hat issue 1870279'
(connection reset by peer issue in socat versions 1.7.3.3 to 1.7.4.0) which
further causes crashes during SST using mariabackup (when openssl is used).

Also fixed broken logic of automatic generation of the Diffie-Hellman parameters
for socat version less than 1.7.3 (which defaults to 512-bit values instead of
2048-bit ones).

Recent adventures in liburing and btrfs have shown up some kernel
version dependent bugs. Having a bug report of accurace kernel version
can start to correlate these errors sooner.

On Linux, /proc/version contains the kernel version.

FreeBSD has kern.version (per man 8 sysctl), so include that too.

depending on how fast the hareware is and optimizer development
it might kill EXPLAIN at some random point in time (generally unrelated
to the Bug#28598 it was supposed to test) or EXPLAIN might finish
before the KILL and the test will fail.

We do not really care about the exact result; we only care that the

when some statistics were updated in the background or when some

MDEV-21027 Assertion `part_share->auto_inc_initialized || !can_use_for_auto_inc_init()' failed in ha_partition::set_auto_increment_if_higher

ha_partition::set_auto_increment_if_higher expects
part_share->auto_inc_initialized is true or can_use_for_auto_inc_init()
is false (but as the comment of this method says, it returns false
only if we use Spider engine with DROP TABLE or ALTER TABLE query).
However, part_share->auto_inc_initialized becomes true only after all
partitions are opened (since 6dce6aec).

Therefore, I added a conditional expression in order to read all
partitions when we execute REPLACE on a table that has an
AUTO_INCREMENT column.

Current Debian package revision scheme when using
debian/autobake-deb.sh script is:
  '1:VERSION+maria~LSBNAME'

For example if VERSION can be like 10.6.8 and LSBNAME is
buster then version and revision is:
  '1:10.6.8+maria~buster'
Which can lead to problem as distro code names can be lexical unordered.

For example Debian LSBNAME's can be:
  Codename Buster is Debian version 10
  Codename Bookworm is Debian version 11

This happens because in ASCII table
Buster first two digits are 'Bu' and they are in hex 0x42 and 0x75
and Bookworm first digits 'Bo' are they are in hex 0x42 and 0x6F
When apt is upgrading it  means that:
  1:10.6.8+maria~buster is bigger than 1:10.6.8+maria~bookworm
and that leads to problems in dist-upgrade process

To solve problem revision format is changed to:
  '1:VERSION+maria~(deb|ubu)LSBVERSION'

Example for Debian 11 is now:
  1:10.6.8+maria~deb11

and for Ubuntu 22.04 is now:
  1:10.6.8+maria~ubu2204

There are new Variables
 * VERSION which contains whole version string
 * LSBVERSION which contains LSB version of distro
 * LSBID which contains LSB ID (Debian or Ubuntu)
added to debian/autobake-deb.sh.

Also CODENAME is change to LSBNAME as it's more declaritive

MDEV-26127 Assertion `err != DB_DUPLICATE_KEY' failed or InnoDB: Failing assertion: id != 0 on ALTER ... REBUILD PARTITION

During rebuild of partition, the partitioning engine calls
alter_close_table(), which does not unlock and close some table
instances of the target table.
Then, the engine fails to rename partitions because there are table
instances that are still locked.

Closing all the table instance of the target table fixes the bug.

Test prior to this change:

PageConverter::update_header(): Remove an unnecessary write.
The field that was originally called FIL_PAGE_FILE_FLUSH_LSN only
made sense for the first page of the system tablespace
(initially, for the first page of each file of the system tablespace).
It never had any meaning for .ibd files, and it lost its original
meaning in MariaDB Server 10.8.1 when
commit b07920b6 (MDEV-27199)
removed the ability to start without ib_logfile0.

If the most significant 32 bits of the LSN are nonzero, this
unnecessary write would write the wrong encryption key identifier
to the page. The first page of any file is never encrypted,
so normally those bytes should be 0 for any .ibd file.

The zoneinfo directory is littered with non-timezone information files.

These frequently contain extensions, not present in real timezone files.

Alo leapseconds is frequently there and is not a timezone file.

The else condition is meant to be here to define the functions
if the Red Hat include file isn't there.
