accessing freed memory.
Before XMLCOL::WriteColumn() Tdbp->Clist gets assigned
a nodelist in

      Clist = RowNode->SelectNodes(g, Colname, Clist);

which is RowNode->Doc->Xop->nodesetval.

In XMLCOL::WriteColumn()

        ValNode = ColNode->SelectSingleNode(g, Xname, Vxnp);

calls LIBXMLDOC::GetNodeList() again, which frees the previous
XPath object Xop and replaces it with a new one.

In this case RowNode->Doc == ColNode->Doc, so Clist->Listp
points to a freed memory now.

- 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.

This happens when compiled with HAVE_EMBEDDED_PRIVILEGE_CONTROL.
There is a lot of other problems with the above option that should
be fixed at some point

This avoids printing the error
"mysqld: file-key-management-filename  is not set"
which can happen if the file-key-management pluging is statically compiled

Removed the option as it safe to always create the file when we have
created the MariaDB data directories. This fixes this issue not only
for debian but for all MariaDB users.

This patch let's you specify not only user to use but also group that
MariaDB should use.

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.

Add test case that reproduces the issue and update wsrep-lib submodule
to include the fix.

MDEV-26953 Assertion `!str || str != Ptr || !is_alloced()' failed in String::copy upon SELECT with sjis

Item::save_str_in_field() passes &Item::str_value as a parameter
to val_str().

Item_func::make_empty_result() also fills and returns str_value.

As a result, in the reported scenario in
Item_func::val_str_from_val_str_ascii()
both "str" and "res" pointed to Item::str_value,
which made the DBUG_ASSERT inside String::copy()
(preventing copying to itself) crash:

  if ((null_value= str->copy(res->ptr(), res->length(),
                             &my_charset_latin1, collation.collation,
                             &errors)))

Fix:
- Adding a String* parameter to make_empty_result()
- Passing the val_str() parameter to make_empty_string().

Because this test uses a unix socket to check if the
mysql_tzinfo_to_sql generates suitable SQL it cannot work in
embedded mode.

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.

For compatibility this is under an extra option --upgrade-info

The goal here is to install a data directory with the required
info to let mysql_upgrade know that an upgrade isn't required.

Fixed the assert to restore pre-refactoring condition for
calling set_error() equivalent.

cmp_data(): Compare different-length CHAR fields with
the new strnncollsp_nchars function that will pad spaces if needed.

Any InnoDB ROW_FORMAT except the original one that was named
ROW_FORMAT=REDUNDANT in MySQL 5.0.3 will internally store
CHAR(n) columns as variable-length if the character encoding is
variable length. Spaces may be trimmed from the end.
For NOT NULL values, the minimum length is always n*mbminlen.
In cmp_data() we only know the lengths in bytes and we cannot
easily know the ROW_FORMAT.

is_strnncoll_compatible(): Refactored from innobase_mysql_cmp().

innobase_mysql_cmp(): Merged to cmp_whole_field().

cmp_whole_field(): Invoke strnncollsp_nchars for the DATA_MYSQL

MDEV-8652: Partitioned table creation problem when creating from procedure context twice in same session

The problem was solved in in MDEV-7990, this commit contains only test

MDEV-20770 Server crashes in JOIN::transform_in_predicates_into_in_subq upon 2nd execution of PS/SP comparing GEOMETRY with other types.

The Item_in_subselect::in_strategy keeps the value and as the error
happens the condition isn't modified. That leads to wrong ::fix_fields
execution on second PS run. Also the select->table_list is merged
but not restored if an error happens, which causes hanging loops on
the third PS execution.

This bug may affect the queries that uses a grouping derived table with
grouping list containing references to columns from different tables if
the optimizer decides to employ the split optimization for the derived
table. In some very specific cases it may affect queries with a grouping
derived table that refers only one base table.
This bug was caused by an improper fix for the bug MDEV-25128. The fix
tried to get rid of the equality conditions pushed into the where clause
of the grouping derived table T to which the split optimization had been
applied. The fix erroneously assumed that only those pushed equalities
that were used for ref access of the tables referenced by T were needed.
In fact the function remove_const() that figures out what columns from the
group list can be removed if the split optimization is applied can uses
other pushed equalities as well.
This patch actually provides a proper fix for MDEV-25128. Rather than
trying to remove invalid pushed equalities referencing the fields of SJM
tables with a look-up access the patch attempts not to push such equalities.

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
