This function trivially returns false

The SQL thread and a user connection executing SHOW SLAVE STATUS
have a race condition on Last_SQL_Errno, such that a slave which
previously errored and stopped, on its next start, SHOW SLAVE STATUS
can show that the SQL Thread is running while the previous error is
also showing.

The fix is to move when the last error is cleared when the SQL
thread starts to occur before setting the status of
Slave_SQL_Running.

Thanks to Kristian Nielson for his work diagnosing the problem!

Remove TLSv1.1 from the default tls_version system variable.

Output a warning if TLSv1.0 or TLSv1.1 are selected.

Thanks Tingyao Nian for the feature request.

There is a list of plugins in the WiX configuration file for HeidiSQL,
and the installer only installs DLLs from that list although the HeidiSQL
portable archive may include other plugins.

This commit adds client_ed25519.dll to this list and also rearranges

Test case is starting too many servers that are not really
needed for original problem testing. This fix reduces
number of servers to make test case smaller and more
robust.

Problem was that if wsrep_notify_cmd was set it was called
with a new status "joined" it tries to connect to the server
to update some table, but the server isn't initialized yet,
it's not listening for connections. So the server waits for the
script to finish, script waits for mariadb client to connect,
and the client cannot connect, because the server isn't listening.

Fix is to call script only when Galera has already formed a
view or when it is synched or donor.

This fix also enables following test cases:
* galera.MW-284
* galera.galera_binlog_checksum
* galera_var_notify_ssl_ipv6

innodb_monitor_validate(): Let item_val_str() allocate the memory
in THD, so that it will be available to innodb_monitor_update().
In this way, there is no need to allocate another buffer, and
no problem if the call to innodb_monitor_update() is skipped due
to an invalid value that is passed to another configuration parameter.

There are some other callers to st_mysql_sys_var::val_str()
that validate configuration parameters that are related to FULLTEXT INDEX,
but they will allocate memory by invoking thd_strmake().

Currently include/have_innodb_4k.inc etc. files only check that the
server is running with the corresponding page size. I think it would
be more convenient if they actually enforced the setting.

The test innodb_zip.index_large_prefix_4k would not run unless it is
invoked as
./mtr --mysqld=--innodb-page-size=4k innodb_zip.index_large_prefix_4k

This test was originally developed to cover an option that was removed
in commit 0c92794d. Starting with
MariaDB Server 10.2, which introduced innodb_default_row_format=dynamic,
the option innodb_large_prefix had become useless.

Let us remove some of the stale tests and adjust the outcome to the
expected behaviour.

Let us avoid inserting the rows fid=714 and fid=715, because we would
evaluate g=NULL for them, and NULL values are not allowed in InnoDB
SPATIAL INDEX.

Also, let the test run on any page size, and on non-debug builds.

ibuf_set_bitmap_for_bulk_load(): Port a bug fix that was made as part of
commit 165564d3 (MDEV-30009)
in MariaDB Server 10.5.19.

Port the test case from MySQL to MariaDB:

MySQL fix Bug#33813951, Change-Id: I2448e3f2f36925fe70d882ae5681a6234f0d5a98.

Function test_simple_temporal() from MySQL ported from C++ to pure C.

This includes one change:
-  DIE_UNLESS(field->type == MYSQL_TYPE_DATETIME);
+  DIE_UNLESS(field->type == MYSQL_TYPE_TIMESTAMP);

The bound param of SELECT ? is TIMESTAMP in this code.
MySQL returns it back as DATETIME. MariaDB preserves TIMESTAMP.

Code packaged for commit by Daniel Black.

The problem was that parallel replication of temporary tables using
statement-based binlogging could overlap the COMMIT in one thread with a DML
or DROP TEMPORARY TABLE in another thread using the same temporary table.
Temporary tables are not safe for concurrent access, so this caused
reference to freed memory and possibly other nastiness.

The fix is to disable the optimisation with overlapping commits of one
transaction with the start of a later transaction, when temporary tables are
in use. Then the following event groups will be blocked from starting until
the one using temporary tables is completed.

This also fixes occasional test failures of rpl.rpl_parallel_temptable seen
in Buildbot.

recalculate long unique hash in Write_rows_log_event
and Update_rows_log_event.

normally generated columns (stored and indexed virtual)
are deterministic and their values don't need to be recalculated
on the slave as they're already present in the row image.
but the long unique hash function was changed in MDEV-27653,
so a row event from the old master will have the old hash,
but a table created on the new slave will need a new hash.

don't enable bulk insert when table->s->long_unique_table

Field_blob::value's from it, and restore them when record[0]

The problem is in manager/worker communication when worker sends
WARNINGS and then TESTRESULT. If manager yet didn't read WARNINGS
response both responses get into the same buffer, can_read() will
indicate we have data only once and we must read all the data from the
socket at once. Otherwise TESTRESULT response is lost and manager
waits it forever.

The fix now instead of single line reads the socket in a loop. But if
there is only one response in the buffer the second read will be
blocked waiting until new data arrives. That can be overcame by
blocking(0) which sets the handle into non-blocking mode. If there is
no data second read just returns undef.

The problem is non-blocking mode is not supported by all perl flavors
on Windows. Strawberry and ActiveState do not support it. Cygwin and
MSYS2 do support. There is some ioctl() hack that was known to "work"
but it doesn't do what is expected (it does not return data when there
is data). So for Windows if it is not Cygwin we disable the fix.

MSYS2 is basically Cygwin, except it has more easy installation (but
with tools which are not used) and it has some more control of path
conversion via MSYS2_ARG_CONV_EXCL and MSYS2_ENV_CONV_EXCL. So it
should be more Windows-friendly than Cygwin.

Installation

Similar to Cygwin, except installing patch requires additional command
run from shell:

    pacman -S patch

MSYS2 still doesn't work as it returns wierd "Bad address" when
exec-ing forked process from create_process(). Same exec from
standalone perl -e runs just fine... :(

Cygwin is more Unix-oriented. It does not treat \n as \r\n in regexps
(fixed by \R), it supplies Unix-style paths (fixed by
mixed_path()). It does some cleanup on paths when running exe, so it
will be different in exe output (like with $exe_mysqld, comparing
basename() is enough).

Cygwin installation

1. Just install latest perl version (only base package) and
   patchutils from cygwin-setup;
2. Don't forget to add c:\cygwin64\bin into system path
   before any other perl flavors;
3. There is path-style conflict (see below), you must replace
   c:\cygwin64\bin\sh.exe with the wrapper. Run MTR with
   --cygwin-subshell-fix=do for that. Make sure you are running Cygwin
   perl for the option to work.
4. Restart buildbot via net stop buildbot; net start buildbot

Path-style conflict of Cygwin-ish Perl

Some exe paths are passed to mysqltest which are executed by a native
call. This requires native-style paths (\-style). These exe paths also
executed by Perl itself. Either by MTR itself which is not so
critical, but also by tests' --perl blocks which is impossible to
change. And if Perl detects shell-expansion or uses pipe command it
passess this exe path to /bin/sh which is Cygwin-compiled bash that
cannot work with \-style (or at least in -c processing). Thus we require
\-style on some parts of MTR execution and /-style on another parts.

The examples of tests which cover these different parts are:

    main.mysqlbinlog_row_compressed \
    main.sp_trans_log

That could be great to force Perl to use something different from
/bin/sh, but unfortunately /bin/sh is compiled-in into binary. So the
only solution left is to overwrite /bin/sh with some wrapper script
which passes the command to cmd.exe instead of bash.

See "Path-style conflict" in "MDEV-30836 MTR Cygwin fix" for explanation.
