- Go back to using $MAJOR_VER instead of hard-coded version strings where
  possible.

- Default to 'auto' in NUMJOBS instead of just 1. Will make mysql-test-run
  faster.

- Unify autopkgtest with latest version in Debian, use eatmydata to make
  mysql-test-run faster.

- Salsa-CI: Remove obsolete 'artifacts: true' as that is the default value.

- Salsa-CI: Clean away obsolete temporary fixes.

- Salsa-CI: Unify with salsa-ci.yml in Debian, including test upgrades
  from Bullseye to Debian unstable.

MDEV-22708 Assertion `!mysql_bin_log.is_open() || thd.is_current_stmt_binlog_format_row()' failed in Delayed_insert::handle_inserts and in Diagnostics_area::set_eof_status

Function `upgrade_lock_type` should check global binlog_format variable
instead of thread one.

Updated libmariadb and enable the test.

GCC 4.8.5 would crash when compiling trx_purge_truncate_history().
Let us try to avoid that by disabling optimizations for the function.

The test was passing some uninitialized data to libmariadb.
Mostly, the MemorySanitizer wrapper of send() detected that
some bytes were uninitialized.

The test_mdev19838() is for now disabled under MemorySanitizer,
to be fixed in MDEV-26761.

Variable wsrep_forced_binlog_format has higher priority than
binlog_format. In situation where STATEMENT is used and DELAYED INSERT
is executing we should fall back to non-delay INSERT.

Using `innodb_thread_concurrency` will call `wsrep_thd_is_aborting` to
check WSREP thread state. This call should be protected by taking
`LOCK_thd_data` before entering function.
Applier and TOI threads should no be affected with usage of
`innodb_thread_concurrency` variable so returning before any checks.

If a table has no unique indexes, write set key information will be collected on all columns in the table.
The write set key information has space only for max 3500 bytes for individual column, and if a varchar colummn of such non-primary key table is longer than
 this limit, currently a crash follows.
The fix in this commit, is to truncate key values extracted from such long varhar columns to max 3500 bytes.
This may potentially lead to false positive certification failures for transactions, which operate on separate cluster nodes, and update/insert/delete table rows, which differ only in the part of such long columns after 3500 bytes border.

In commit 45ed9dd9 (MDEV-23855)
when removing fil_system.LRU we failed to rate-limit the output
for reporting violations of innodb_open_files or open_files_limit.

If the server is run with a small limit of open files that is
well below the number of .ibd files that are being accessed by
the workload, and if at the same time innodb_log_file_size is
very small so that log checkpoints will occur frequently,
the process of enforcing the open files limit may be run very often.

fil_space_t::try_to_close(): Display at most one message per call,
and only if at least 5 seconds have elapsed since the last time a
message was output.

fil_node_open_file(): Only output a summary message if
fil_space_t::try_to_close() displayed a message during this run.
(Note: multiple threads may execute fil_node_open_file() on
different files at the same time.)

fil_space_t::get(): Do not dereference a null pointer if n & STOPPING.
This was caught by the test case below.

Unfortunately, it is not possible to create a fully deterministic
test case (expecting exactly 1 message to be emitted). The following with
--innodb-open-files=10 --innodb-log-file-size=4m
would occasionally fail to find the message in the log:

--source include/have_innodb.inc
--source include/have_partition.inc
--source include/have_sequence.inc

call mtr.add_suppression("InnoDB: innodb_open_files=10 is exceeded");

FIXME: Part of the MDEV-20699 test is disabled due to
nonderterministic result.

Normally we disable caching of routines in "SHOW CREATE".
Introduce an exception, if debug_dbug="+d,cache_sp_in_show_create".
lock_sync.test needs a way to populate the cache without side effects,
or else it runs into debug_sync timeouts.

So, this possibility to cache will be remain only for very special tests.

Occasionally, after restart, additional transactions will have been
executed, possibly related to innodb_stats_auto_recalc.

We should only care that the transaction ID sequence does
not go backwards.

Apparently, slow shutdown is not necessary anymore after MDEV-15912 fix

Let us mask the actual values of the defragmentation-related fields,
because they may vary. Also, remove the dependency on purge,
and instead delete records by a ROLLBACK of INSERT.

The reason for this behavior is that SP get cached, per connection.
The stored_program_cache is size of this cache, which amounts to 256
routines by default. A compiled stored procedure can easily be several
megabytes in size. Thus calling SHOW CREATE PROCEDURE for all stored
procedures, like mysqldump does, can require significant amount of memory.

Fixed by bypassing the cache for "SHOW CREATE". This should normally be
fine also perfomance-wise, as cache is meant to be used for repeated
execution, not repeated SHOW CREATEs.

Added a test to verify that CREATE PROCEDURE + SHOW CREATE PROCEURE do not
cache, i.e amount of allocated memory does not change.

Note, there is a change in existing behavior in an edge case :
If "SHOW CREATE PROCEDURE p1" called from p1, after p1 was altered, now
this will now return altered code. Previour behavior - relied on caching
and would return old code. The previous behavior might was not necessarily
correct.

Reduce usage of current_select (because it does not always point on the correct

Change context for all classes inherited from Item_ident (was only for Item_field) in case of pushing down it to HAVING.

Now name resolution context have to have SELECT_LEX reference if the context is present.
