AWK is used in autobake-debs.sh for printing information
about created DEB packages.

AWK in used in Debian SysV-init and postinst scripts to determine
is there enough space starting MariaDB database or create new
database to target destination.
These AWK scripts can be rewrited to use pure SH or help
using Coreutils which is mandatory for usage of MariaDB currently.
Reasoning behind this is to get rid of one very less used dependency

log_free_check(): Assert that the caller must not hold
exclusive lock_sys.latch. This was the case for calls from
ibuf_delete_for_discarded_space(). This caused a deadlock with
another thread that would be holding a latch on a dirty page
that would need to be written so that the checkpoint would advance
and log_free_check() could return. That other thread was waiting
for a shared lock_sys.latch.
fil_delete_tablespace(): Do not invoke ibuf_delete_for_discarded_space()
because in DDL operations, we will be holding exclusive lock_sys.latch.

page_cleaner_flush_pages_recommendation(): If dirty_pct is
between innodb_max_dirty_pages_pct_lwm
and innodb_max_dirty_pages_pct,
scale the effort relative to how close we are to
innodb_max_dirty_pages_pct.
The previous formula was missing a multiplication by 100.

This addition to MDEV-30804 is relevant for 10.6+, it excludes
the mixed transaction section using both innodb and aria storage
engines from the galera_var_replicate_aria_off test, since such
transactions cannot be executed unless aria supports two-phase
transaction commit. No additional tests are required as this
commit fixes the mtr test itself.

When commit a5a2ef079cec378340d8b575aef05974b0b3442e
implemented asynchronous doublewrite, the writes via
the doublewrite buffer started to be counted incorrectly,
without multiplying them by innodb_page_size.
srv_export_innodb_status(): Correctly count the
Innodb_data_written.
buf_dblwr_t: Remove submitted(), because it is close to written()
and only Innodb_data_written was interested in it. According to
its name, it should count completed and not submitted writes.

GTID State
If a replica failed to update the GTID slave state when committing
an XA PREPARE, the replica would retry the transaction and get an
out-of-order GTID error. This is because the commit phase of an XA
PREPARE is bifurcated. That is, first, the prepare is handled by the
relevant storage engines. Then second, the GTID slave state is
updated as a separate autocommit transaction. If the second phase
fails, and the transaction is retried, then the same transaction is
attempted to be committed again, resulting in a GTID out-of-order
error.
This patch fixes this error by immediately stopping the slave and
reporting the appropriate error. That is, there was logic to bypass
the error when updating the GTID slave state table if the underlying
error is allowed for retry on a parallel slave. This patch adds a
parameter to disallow the error bypass, thereby forcing the error
state to still happen.

aria_log_dir_path is used
Fixing buildbot failures on mariabackup.aria_log_dir_path_rel.
The problem was that directory_exists() was called with the
relative aria_log_dir_path value, while the current directory
in mariadb-backup is not necessarily equal to datadir when MTR is running.
Fix:
- Moving building the absolute path un level upper:
from the function copy_back_aria_logs() to the function copy_back().
- Passing the built absolute path to both directory_exists() and
copy_back_aria_logs() as a parameter.

This bug caused server crash when processing a multi-update statement that
used views if optimizer tracing was enabled.
The bug was introduced in the patch for MDEV-30539 that could incorrectly
detect the most top level selects of queries if views were used in them.

- `mariadb-backup --backup` was fixed to fetch the value of the
@@aria_log_dir_path server variable and copy aria_log* files
from @@aria_log_dir_path directory to the backup directory.
Absolute and relative (to --datadir) paths are supported.
Before this change aria_log* files were copied to the backup
only if they were in the default location in @@datadir.
- `mariadb-backup --copy-back` now understands a new my.cnf and command line
parameter --aria-log-dir-path.
`mariadb-backup --copy-back` in the main loop in copy_back()
(when copying back from the backup directory to --datadir)
was fixed to ignore all aria_log* files.
A new function copy_back_aria_logs() was added.
It consists of a separate loop copying back aria_log* files from
the backup directory to the directory specified in --aria-log-dir-path.
Absolute and relative (to --datadir) paths are supported.
If --aria-log-dir-path is not specified,
aria_log* files are copied to --datadir by default.
- The function is_absolute_path() was fixed to understand MTR style
paths on Windows with forward slashes, e.g.
--aria-log-dir-path=D:/Buildbot/amd64-windows/build/mysql-test/var/...

fp->field_length was unsigned and therefore the negative
condition around it.
Backport of cc182aca9352 fixes it, however to correct the
consistent use of types pcf->Length needs to be unsigned
too.
At one point pcf->Precision is assigned from pcf->Length so
that's also unsigned.
GetTypeSize is assigned to length and has a length argument.
A -1 default value seemed dangerious to case, so at least 0
should assert if every hit.

This patch fixes the problem by adding a new rule booleat_test.
This makes the grammar clearer and less conflicting.
Additionally, fixing %prec in this grammar branch:
- | boolean_test IS NULL_SYM %prec PREC_BELOW_NOT
+ | boolean_test IS NULL_SYM %prec IS
to have consistently "%prec IS" in all grammar branches starting
with "boolean_test IS ...".
It's not clear why these three rules needed different %prec before the fix:
- boolean_test IS TRUE
- boolean_test IS UNKNOWN
- boolean_test IS NULL

This bug manifested itself when the server processed a query containing
a derived table over union whose ORDER BY clause included a subquery
with unresolvable column reference. For such a query the server crashed
when trying to resolve column references in the ORDER BY clause used by
union.
For any union with ORDER BY clause an extra SELECT_LEX structure is created
and it is attached to SELECT_LEX_UNIT structure of the union via the field
fake_select_lex. The outer context for fake_select_lex must be the same as
for other selects of the union. If the union is used in the FROM list of
a derived table then the outer context for fake_select_lex must be set to
NULL in line with other selects of the union. It was not done and it
caused a crash when searching for possible resolution of an unresolvable
column reference occurred in a subquery used in the ORDER BY clause.

This issue happens when race condition happens when DDL
and fts optimize thread. DDL adds the new index to fts cache.
At the same time, fts optimize thread clears the cache
and reinitialize it. Take cache init lock before reinitializing
the cache. fts_sync_commit() should take dict_sys mutex
to avoid the deadlock with create index.

Assertion `thd->mdl_context.is_lock_owner()` fires when a client is
disconnected, while transaction and and a table is opened through
`HANDLER` interface.
Reason for the assertion is that when a connection closes, its ongoing
transaction is eventually rolled back in
`Wsrep_client_state::bf_rollback()`. This method also releases explicit
which are expected to survive beyond the transaction lifetime.
This patch also removes calls to `mysql_ull_cleanup()`. User level
locks are not supported in combination with Galera, making these calls
unnecessary.

The glibc headers declare fallocate only if _GNU_SOURCE is defined.
Without this change, the probe fails with C compilers which do not
support implicit function declarations even if the system does in
fact support the fallocate function.
Upstream rocksdb does not need this because the probe is run with the
C++ compiler, and current g++ versions define _GNU_SOURCE
automatically.

This commit adds a new 'no-sni' option to socat which is required to
properly authenticate with newer socat versions (after version 1.7.4+).
This option is needed to disable the automatic use of the SNI feature
(Server Name Indication) since the SST script directly specifies the
commonname if necessary and automatic activation of the SNI feature
is unnecessary in such scenarios.

This bug could affect multi-update statements as well as single-table
update statements processed as multi-updates when the where condition
contained a range condition over a non-indexed varchar column. The
optimizer calculates selectivity of such range conditions using histograms.
For each range the buckets containing endpoints of the the range are
determined with a procedure that stores the values of the endpoints in the
space of the record buffer where values of the columns are usually stored.
For a range over a varchar column the value of a endpoint may exceed the
size of the buffer and in such case the value is stored with truncation.
This truncations cannot affect the result of the calculation of the range
selectivity as the calculation employes only the beginning of the value
string. However it can trigger generation of an unexpected error on this
truncation if an update statement is processed.
This patch prohibits truncation messages when selectivity of a range
condition is calculated for a non-indexed column.

The motivation of this change is to allow undo pages for temporary tables
to be marked free as often as possible, so that we can avoid buf_pool.LRU
eviction (and writes) of undo pages that contain data that is
no longer needed. For temporary tables, no MVCC or purge of history
is needed, and reusing cached undo log pages might not help that much.
It is possible that this may cause some performance regression due to
more frequent allocation and freeing of undo log pages, but I only
measured a performance improvement.
trx_write_serialisation_history(): Never cache temporary undo log pages.
trx_undo_reuse_cached(): Assert that the rollback segment is persistent.
trx_undo_assign_low(): Add template<bool is_temp>. Never invoke
trx_undo_reuse_cached() for temporary tables.

srv_prepare_to_delete_redo_log_file():
Replace a debug assertion with a wait in debug builds.
Starting with commit 7e31a8e7fa97a87fc164381588d172bf0e76abb6
the debug assertion ut_ad(!os_aio_pending_writes())
could occasionally fail, while it would hold in core dumps of crashes.
The failure can be reproduced more easily by adding a sleep to the
write completion callback function, right before releasing to
write_slots.
srv_start(): Remove a bogus debug assertion
ut_ad(!os_aio_pending_writes()) that could fail in
mariadb-backup --prepare. In an rr replay trace, we had
buf_pool.flush_list.count==0 but write_slots->m_cache.m_pos==1
and buf_page_t::write_complete() was executing u_unlock().
