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
the list alphabetically, so it is easier to verify its contents
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 0c92794db3. 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.

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.
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.

run_test_server() is actually manager main loop. We move out this
function into Manager package and split into run() and
parse_protocol(). The latter is needed for the fix. Moving into
separate package helps to make some common variables which was local
to run_test_server().
Functions from the main package is now prefixed with main:: (should be
reorganized somehow later or auto-imported).
Create test for for case insensitive gives a basic warning on creating
a test file and the next thing a user might see is an abort.
ProtectHome and other systemd setting protect system services from
accessing user data. Unfortunately some of our users do put things
on /home due space or other reasons.
Rather than enumberate the systemd options in a very clunkly fragile
way we put an error associated with the "Can't create test file" and
hope the user can work it out from there.

Fixed memory leak taken place on executing a prepared statement or
a stored routine that querying a view and this view constructed
on an information schema table. For example,
Lets consider the following definition of the view 'v1'
CREATE VIEW v1 AS SELECT table_name FROM information_schema.views
ORDER BY table_name;
Querying this view in PS mode result in hit of assert.
PREPARE stmt FROM "SELECT * FROM v1";
EXECUTE stmt;
EXECUTE stmt; (*)
Running the statement marked with (*) leads to a crash in case
server build with mode to control allocation of a memory from SP/PS
memory root on the second and following executions of PS/SP.
The reason of leaking the memory is that a memory allocated on
processing of FRM file for the view requested from a PS/PS memory
root meaning that this memory be released only when a stored routine
be evicted from SP-cache or a prepared statement be deallocated
that typically happens on termination of a user session.
To fix the issue switch to a memory root specially created for
allocation of short-lived objects that requested on parsing FRM.
In case a table accessed by a PS/SP is dropped after the first execution of
PS/SP and a view created with the same name as a table just dropped then
the second execution of PS/SP leads to allocation of a memory on SP/PS
memory root already marked as read only on first execution.
For example, the following test case:
CREATE TABLE t1 (a INT);
PREPARE stmt FROM "INSERT INTO t1 VALUES (1)";
EXECUTE stmt;
DROP TABLE t1;
CREATE VIEW t1 S SELECT 1;
--error ER_NON_INSERTABLE_TABLE
EXECUTE stmt; # (*)
DROP VIEW t1;
will hit assert on running the statement 'EXECUTE stmt' marked with (*)
when allocation of a memory be performed on parsing the view.
Memory allocation is requested inside the function mysql_make_view
when a view definition being parsed. In order to avoid an assertion
failure, call of the function mysql_make_view() must be moved after
invocation of the function check_and_update_table_version().
It will result in re-preparing the whole PS statement or current
SP instruction that will free currently allocated items and reset
read_only flag for the memory root.
Moved call of the function check_and_update_table_version() just
before the place where the function extend_table_list() is invoked
in order to avoid allocation of memory on a PS/SP memory root
marked as read only. It happens by the reason that the function
extend_table_list() invokes sp_add_used_routine() to add a trigger
created for the table in time frame between execution the statement
EXECUTE `stmt_id` .
For example, the following test case
create table t1 (a int);
prepare stmt from "insert into t1 (a) value (1)";
execute stmt;
create trigger t1_bi before insert on t1 for each row
set @message= new.a;
execute stmt; # (*)
adds the trigger t1_bi to a list of used routines that involves
allocation of a memory on PS memory root that has been already marked
as read only on first run of the statement 'execute stmt'.
In result, when the statement marked with (*) is executed it results in
assert hit.
To fix the issue call the function check_and_update_table_version()
before invocation of extend_table_list() to force re-compilation of
PS/SP that resets read-only flag of its memory root.
This patch adds support for controlling of memory allocation
done by SP/PS that could happen on second and following executions.
As soon as SP or PS has been executed the first time its memory root
is marked as read only since no further memory allocation should
be performed on it. In case such allocation takes place it leads to
the assert hit for invariant that force no new memory allocations
takes place as soon as the SP/PS has been marked as read only.
The feature for control of memory allocation made on behalf SP/PS
is turned on when both debug build is on and the cmake option
-DWITH_PROTECT_STATEMENT_MEMROOT is set.
The reason for introduction of the new cmake option
-DWITH_PROTECT_STATEMENT_MEMROOT
to control memory allocation of second and following executions of
SP/PS is that for the current server implementation there are too many
places where such memory allocation takes place. As soon as all such
incorrect allocations be fixed the cmake option
-DWITH_PROTECT_STATEMENT_MEMROOT
can be removed and control of memory allocation made on second and
following executions can be turned on only for debug build. Before
every incorrect memory allocation be fixed it makes sense to guard
the checking of memory allocation on read only memory by extra cmake
option else we would get a lot of failing test on buildbot.
Moreover, fixing of all incorrect memory allocations could take pretty
long period of time, so for introducing the feature without necessary
to wait until all places throughout the source code be fixed it makes
sense to add the new cmake option.
- Server aborts when table doesn't have referenced index.
This is caused by 5f09b53bdb (MDEV-31086).
While iterating the foreign key constraints, we fail to
consider that InnoDB doesn't have referenced index for
it when foreign key check is disabled.
For clang compiler the compiler's flag -Wno-unused-but-set-variable
was set based on compiler version. This approach could result in
false positive detection for presence of compiler option since
only first three groups of digits in compiler version taken into account
and it could lead to inaccuracy in determining of supported compiler's
features.
Correct way to detect options supported by a compiler is to use
the macros MY_CHECK_CXX_COMPILER_FLAG and to check the result of
variable with prefix have_CXX__
So, to check whether compiler does support the option
-Wno-unused-but-set-variable
the macros
MY_CHECK_CXX_COMPILER_FLAG(-Wno-unused-but-set-variable)
should be called and the result variable
have_CXX__Wno_unused_but_set_variable
be tested for assigned value.
innodb_max_purge_lag_wait_update(): Return immediately if we are
in high_level_read_only mode.
srv_wake_purge_thread_if_not_active(): Relax a debug assertion.
If srv_read_only_mode holds, purge_sys.enabled() will not hold
and this function will do nothing.
trx_t::commit_in_memory(): Remove a redundant condition before
invoking srv_wake_purge_thread_if_not_active().
Spider connection string is a comma-separated parameter definitions,
where each definition is of the form "<param_title> <param_value>",
where <param_value> is quote delimited on both ends, with backslashes
acting as an escaping prefix.
Despite the simple syntax, the existing spider connection string
parser was poorly-written, complex, hard to reason and error-prone,
causing issues like the one described in MDEV-31117. For example it
treated param title the same way as param value when assigning, and
have nonsensical fields like delim_title_len and delim_title.
Thus as part of the bugfix, we clean up the spider comment connection
string parsing, including:
- Factoring out some code from the parsing function
- Simplify the struct `st_spider_param_string_parse`
- And any necessary changes caused by the above changes
The test innodb.row_size_error_log_warnings_3 that was added in
commit 372b0e6355 (MDEV-20194)
failed to take into account the earlier adjustment in
commit cf574cf53b (MDEV-27634)
that is specific to many GNU/Linux distributions for the s390x.
buf_read_page_low(): Remove an error message that could be triggered
by buf_read_ahead_linear() or buf_read_ahead_random().
This is a backport of commit c9eff1a144
from MariaDB Server 10.5.
buf_read_ahead_random(), buf_read_ahead_linear(): Avoid read-ahead
of the last page(s) of ROW_FORMAT=COMPRESSED tablespaces that use
a page size of 1024 or 2048 bytes. We invoke os_file_set_size() on
integer multiples of 4096 bytes in order to be compatible with
the requirements of innodb_flush_method=O_DIRECT regardless of the
physical block size of the underlying storage.
This change must be null-merged to MariaDB Server 10.5 and later.
There, out-of-bounds read-ahead should be handled gracefully
by simply discarding the buffer page that had been allocated.

When the SQL driver thread goes to wait for room in the parallel slave
worker queue, there was a race where a kill at the right moment could
be ignored and the wait proceed uninterrupted by the kill.
Fix by moving the THD::check_killed() to occur _after_ doing ENTER_COND().
This bug was seen as sporadic failure of the testcase rpl.rpl_parallel

Restore code to make InnoDB choose the second transaction as a deadlock
victim if two transactions deadlock that need to commit in-order for
parallel replication. This code was erroneously removed when VATS was
