The --skip-write-binlog message was confusing that it only had
an effect if the galera was enabled. There are uses beyond galera
so we apply SET SESSION SQL_LOG_BIN=0 as implied by the option
without being conditional on the wsrep status.
Remove wsrep.mysql_tzinfo_to_sql_symlink{,_skip} tests as they offered
no additional coverage beyond main.mysql_tzinfo_to_sql_symlink as no

Introduced a variant of the galera.mariadb_tzinfo_to_sql as
galera.mysql_tzinfo_to_sql, which does testing using the mysql client

Starting with 10.3, an assertion would fail on the rollback of

DICT_ERR_IGNORE_RECOVER_LOCK: Include also DICT_ERR_IGNORE_FK_NOKEY

FOREIGN KEY constraints of a table were incomplete, the table
would fail to load until rollback, and in 10.3 or later an assertion
would fail that the rollback was not protected by a table IX lock.
Thanks to commit 9de2e60d74 there
will be no problems to enforce subsequent FOREIGN KEY operations
even though a table with invalid REFERENCES clause was loaded.
the bug was that in_vector array in Item_func_in was allocated in the
statement arena, not in the table->expr_arena.

Remove TABLE_ARENA, that was introduced in 5acd391e8b to force

wrong arena and didn't persist. now they do)
The partitioning engine does not support the table-level DATA/INDEX
DIRECTORY specification.
If one create a non-partitioned table with the DATA/INDEX DIRECTORY
option and then performs ALTER TABLE ... PARTITION BY on it, the
DATA/INDEX DIRECTORY specification of the old schema is ignored.
The behavior might be a bit surprising for users because the value
of a usual table option applies to all the partitions. Thus, we raise
a warning on such ALTER TABLE ... PARTITION BY.
mariabackup does not load dictionary during backup, but it loads
tablespaces, that is why fil_system.max_assigned_id is not set with
dict_check_tablespaces_and_store_max_id(). There is no sense to issue the
warning during backup.
As main() invokes parse_page() when -S or -D are set, it can be a case
when parse_page() is invoked when -D filename is not set, that is why
any attempt to write to page dump file must be done only if the file

Problem: In regular replication, when master binlogged using statement format
slave might not have written an event to its binary log when the Query
event aimed at a temporary table.
Specifically this was observed with LOAD DATA INFILE.
This effect was possible because unlike master slave holds temporary
tables in its pool and the master side check of existence of a
temporary table at the format bin-logging decision did not apply.
Solution: replace THD::has_thd_temporary_tables() with
THD::has_temporary_tables which allows to identify temporary table
presence on either side.

The 10.5 test error main.grant_kill showed up a incorrect
thread id on a big endian architecture.
The cause of this is the sql_kill_user function assumed the
error was ER_OUT_OF_RESOURCES, when the the actual error was
ER_KILL_DENIED_ERROR. ER_KILL_DENIED_ERROR as an error message
requires a thread id to be passed as unsigned long, however a
user/host was passed.
ER_OUT_OF_RESOURCES doesn't even take a user/host, despite
the optimistic comment. We remove this being passed as an
argument to the function so that when MDEV-21978 is implemented
one less compiler format warning is generated (which would
have caught this error sooner).

DEBUG_SYNC signals can get lost in certain tests due to later
DEBUG_SYNC commands overwriting them. This patch addresses
these issues in three tests: main.query_cache_debug,
main.partition_debug_sync, and
rpl.rpl_dump_request_retry_warning.
Additionally, main.partition_debug_sync needed changes to the
result file (the others did not). The synchronization happened
between two commands, one based on ALTER, the other on DROP.
A new thread/connection was needed to synchronize the DEBUG_SYNC
actions between these commands, thereby changing the result file.
Additional comments were added for clarification.

This commit adds correct handling of binlogs for SST using rsync
or mariabackup. Before this fix, binlogs were handled incorrectly -
- only one (last) binary log file was transferred during SST, which
then led to various failures (for example, when trying to list all
events from the binary log). These bugs were long masked by flaws
in the primitive binlogs handling code in the SST scripts, which
causing binary logs files to be erased after transfer or not added
to the binlog index on the joiner node. Now the correct transfer
of all binary logs (not just the last of the binary log files) has
been implemented both for the rsync (at the script level) and for
the mariabackup (at the level of the main utility code).
This commit also adds a new sst_max_binlogs=<n> parameter, which
can be located in the [sst] section or in the [xtrabackup] section
(historically, supported for mariabackup only, not for rsync), or
in one of the server sections. This parameter specifies the number
of binary log files to be sent to the joiner node during SST. This
option is added for compatibility with old SST scripting behavior,
which can be emulated by setting the sst_max_binlogs=1 (although
in general this can cause problems for the reasons described above).
In addition, setting the sst_max_binlogs=0 can be used to suppress
the transmission of binary logs to the joiner nodes during SST
(although sometimes a single file with the current binary log can
still be transmitted to the joiner, even with sst_max_binlogs=0,
because this sometimes necessary in modes that involve the use of
GTIDs with Galera).
Also, this commit ensures correct handling of paths to various
innodb files and directories in the SST scripts, and fixes some
problems with this that existed in mariabackup utility (which
were associated with incorrect handling of the innodb_data_dir
parameter in some scenarios).
In addition, this commit contains the following enhancements:
1) Added tests for mtr, which check the correct work with binlogs
after SST (using rsync and mariabackup);
2) Added correct handling of slashes at the end of all paths that
the SST script receives as parameters;
3) Improved parsing code for --mysqld-args parameters. Now it
correctly processes the sequence "--" after the name of the
one-letter option;
4) Checking the secret signature during joiner authentication
is made independent of presence of bash (as a unix shell)
in the system and diff utility no longer needed to check
certificates compliance;
5) All directories that are necessary for the correct placement
of various logs are automatically created by SST scripts in
advance (before running mariabackup on the joiner node);
6) Removal of old binary logs on joiner is done using the binlog
index (if it exists) (not only by fixed pattern that based
on the current binlog name, as before);
7) Paths for placing binary logs are correctly processed if they
are set as relative paths (to the datadir);
8) SST scripts are made even more resistant to spaces in filenames
(now for binlogs);
9) In case of failure, SST scripts now always end with an exit
code other than zero;
10) SST script for rsync now correctly create a tar file with
the binlogs, even if the paths to them (in the binlog index
file) are specified as a mix of absolute and relative paths,
and even if they do not match with the datadir path specified
in the current configuration settings.

The rpl.rpl_seconds_behind_master_spike test would sometimes
timeout or take a very long time to complete. This happened
because an MTR DEBUG_SYNC signal would be lost due to a
subsequent call to RESET. I.e., the slave SQL thread would
be paused due to the WAIT_FOR signal being lost, resulting in
either a failed test if the `select master_pos_wait` timeout
occurs first, or a very long run-time if the DBUG_SYNC timeout
occurs first.
The fix ensures that the MTR signal is processed by the slave
SQL thread before issuing the call to RESET

Name resolution code produced errors for valid queries with window
functions (but not for queries which used aggregate functions as
window functions).
Name resolution code worked incorrectly, because window function
objects had is_window_func_sum_expr()=false. This was so, because
mark_as_window_func_sum_expr() was only called for aggregate functions
used as window functions.
The fix is to call it for any window function.
- Revert wrongly record embedded result files. These were either
recorded with normal server (not embedded) or an embedded server
with not default compile option. This can be seen that the committed
result file had replication variables which should never happen.
- Reverted back change of include/is_embedded.inc. One cannot check for
$MYSQL_EMBEDDED as this only tells if there exists an embedded
server, not if the current server we are testing is the embedded
server. This could easily be verified by doing
'mtr sys_vars.sysvars_server_embedded'. This would fail with a wrong
result instead of being marked as skipped as --embedded was not
used.
The assert was caused by an error of XA transaction that had
BINLOG 'base64_string' statement.
The statement failed because of lack of checking whether the encoded
replication event was handled by the slave applier thread.
If it's not the slave applier no error should be generated, but it was
in this case, see a test added.
Fixed along with the idea borrowed the upstream to introduce a check
of which applier executes the replication event and do not
report any error if the applier is a regular server client.
mtr is checking the wrong path for the embedded executable
on out of tree builds.
The is_embedded.inc tests are also checking the version rather
than the MTR MYSQL_EMBEDDED environment variable.
As a result, a few tests are out of date in the result recordings.
This patch addresses two problems with
rpl.rpl_seconds_behind_master_spike
First, --sync_slave_with_master / select master_pos_wait
seems to have a bug where it will hang after all master
events have been executed.
This patch removes the sync_slave_with_master command from
the test, where it not required anyway as it is used to
declare explicit cleanup
Second, the test uses timestamps to ensure that the
Seconds_Behind_Master value does not point to a time too
far in the past. The checks of these timestamps were
too strict, because they could be slightly inconsistent
with the master and the SBM would be counted as invalid
when it was actually correct.
To fix this, a slight buffer was added to the check
to ensure the value is valid but still does not point
too far in the past

In resolving MDEV-27461, BUF_LRU_MIN_LEN (256) is the minimum number of
pages for the innodb buffer pool size. Obviously we need more than just
flushing pages. Taking the 16k page size and its default minimum, an
extra 25% is needed on top of the flushing pages to make a workable buffer
pool.
The minimum innodb_buffer_pool_chunk_size (1M) restricts the minimum
otherwise we'd have a pool made up of different chunk sizes.
The resulting minimum innodb buffer pool sizes are:
Page Size, Previously minimum (startup), with change.
4k 5M 2M
8k 5M 3M
16k 5M 5M
32k 24M 10M
64k 24M 20M
With this patch, SET GLOBAL innodb_buffer_pool_size minimums are
enforced.
The evident minimum system variable size for innodb_buffer_pool_size
is 2M, however this is only setable if using 4k page size. As
the order of the page_size and buffer_pool_size aren't fixed, we can't
hide this change.
Subsequent changes:
* innodb_buffer_pool_resize_with_chunks.test - raised of pool resize due to new
minimums. Chunk size also needed increase as the test was for
pool_size < chunk_size to generate a warning.
* Removed srv_buf_pool_min_size and replaced use with MYSQL_SYSVAR_NAME(buffer_pool_size).min_val
* Removed srv_buf_pool_def_size and replaced constant defination in
MYSQL_SYSVAR_LONGLONG(buffer_pool_size)
* Reordered ha_innodb to allow for direct use of MYSQL_SYSVAR_NAME(buffer_pool_size).min_val
* Moved buf_pool_size_align into ha_innodb to access to MYSQL_SYSVAR_NAME(buffer_pool_size).min_val
* loose-innodb_disable_resize_buffer_pool_debug is needed in the
innodb.restart.opt test so that under debug mode, resizing of the
innodb buffer pool can occur.
The column INFORMATION_SCHEMA.INNODB_LOCKS.LOCK_DATA
would report NULL when the page that contains the locked
record does not reside in the buffer pool.
Pages may be evicted from the buffer pool due to some background
activity, such as the purge of transaction history loading
undo log pages to the buffer pool. The regression tests intentionally
run with a small buffer pool size setting.
To prevent the intermittent test failures, we will filter out the
contents of the LOCK_DATA column from the output.
For MERGE-tables we need to init children list before calling
show_create_table and then detach children before we continue

Problem:
========
A slave’s relay log format description event is used when
calculating Seconds_Behind_Master (SBM). This forces the SBM
value to spike when processing these events, as their creation
date is set to the timestamp that the IO thread begins.
Solution:
========
When the slave generates a format description event, mark the
event as a relay log event so it does not update the
rli->last_master_timestamp variable.

This is the first part of the fixes for MDEV-24097. This commit
contains the fixes for instability when testing Galera and when
restarting nodes quickly:
1) Protection against a "stuck" old SST process during the execution
of the new SST (after restarting the node) is now implemented for
mariabackup / xtrabackup, which should help to avoid almost all
conflicts due to the use of the same ports - both during testing
with mtr, so and when restarting nodes quickly in a production
environment.
2) Added more protection to scripts against unexpected return of
the rc != 0 (in the commands for deleting temporary files, etc).
3) Added protection against unexpected crashes during binlog transfer
(in SST scripts for rsync).
4) Spaces and some special characters in binlog filenames shouldn't
be a problem now (at the script level).
5) Daemon process termination tracking has been made more robust
against crashes due to unexpected termination of the previous SST
process while new scripts are running.
6) Reading ssl encryption parameters has been moved from specific
SST scripts to a common wsrep_sst_common.sh script, which allows
unified error handling, unified diagnostics and simplifies script
revisions in the future.
7) Improved diagnostics of errors related to the use of openssl.
8) Corrections have been made for xtrabackup-v2 (both in tests and in
the script code) that restore the work of xtrabackup with updated
versions of innodb.
9) Fixed some tests for galera_3nodes, although the complete solution
for the problem of starting three nodes at the same time on fast
machines will be done in a separate commit.
No additional tests are required as this commit fixes problems with
existing tests.
