fil_space_encrypt(): Remove the debug check that decrypts the
just encrypted page. We are exercising the decryption of encrypted
pages enough via --suite=encryption,mariabackup. It is a waste of
computing resources to decrypt every page immediately after encrypting it.

The redundant check had been added in
commit 2bedc397 (MDEV-9931).

Fixed a bug introduced in  MDEV-11345, server did not start if
non-english error messages were set in startup parameters.

Added lc_messages=de_DE option into an existing test case.

- dict_table_try_drop_aborted() can generate undo logs. So it should
be avoided after shutdown of background threads.

MDEV-20923:UBSAN: member access within address … which does not point to an object of type 'xid_count_per_binlog'

Problem:
-------
Accessing a member within 'xid_count_per_binlog' structure results in
following error when 'UBSAN' is enabled.

member access within address 0xXXX which does not point to an object of type
'xid_count_per_binlog'

Analysis:
---------
The problem appears to be that no constructor for 'xid_count_per_binlog' is
being called, and thus the vtable will not be initialized.

Fix:
---
Defined a parameterized constructor for 'xid_count_per_binlog' class.

Original patch from Daniel Black <daniel@linux.ibm.com>, backported to 10.1.

Move tokuftdump and tokuft_logprint man pages to storage/tokudb.

The man pages are now part of tokudb-engine cmake component. This change
is mostly for RPM & DEB based packaging generated through CMake & CPack.

Debian upstream already handles this change via the custom scripts in debian/

Problem:
=======
  The problem is that InnoDB doesn't add the table in fts slots if drop table fails. InnoDB marks the table is in fts slots while processing sync message. So the consecutive alter statement assumes that table is in queue and tries to remove it. But InnoDB can't find the table in fts_slots.

Solution:
=========
  i)  Removal of in_queue in fts_t while processing the fts sync message.
  ii) Add the table to fts_slots when drop table fails.

..as they have their own tools that parses those files, such as
opensysusers[1] that handles sysusers file and opentmpfiles[2] that
handles tmpfiles.d settings

Because of this. Move both sysusers and tmpfiles 'if' function
outside systemd function, allowing independent install

Changes done by vicentiu@mariadb.org, from original author patch:

Installing sysusers and tmpfiles without checking for systemd existence
means that by default, cmake will ALWAYS install these files. Our
general policy is we do not install things which are not needed.
However, there is a valid use case when these files are useful, as is
described above.

To allow this, provide an extra switch that can be enabled during
configuring by doing -DINSTALL_SYSTEMD_{SYSUSERS|TMPFILES}=True

This will use the default path INSTALL_SYSTEMD_{SYSUSERS|TMPFILES}DIR
fetched from install_layout.cmake for rpm & deb based layouts
respectively, or they must be overriden if the install_layout is
standalone.

Example:

cmake . -DINSTALL_SYSTEMD_SYSUSERS=True -DINSTALL_SYSTEMD_SYSUSERSDIR=/etc/sysusers.d

These files were installed to:

${INSTALL_SYSTEMD_SYSUSERSDIR}/sysusers.conf
${INSTALL_SYSTEMD_TMPFILESDIR}/tmpfiles.conf

Instead rename the files to more descriptive file names 'mariadb.conf'.

MDEV-21490: binlog tests fail with valgrind: Conditional jump or move depends on uninitialised value in sql_ex_info::init

Problem:
=======
P1) Conditional jump or move depends on uninitialised value(s)
    sql_ex_info::init(char const*, char const*, bool) (log_event.cc:3083)

code: All the following variables are not initialized.
----
  return ((cached_new_format != -1) ? cached_new_format :
    (cached_new_format=(field_term_len > 1 || enclosed_len > 1 ||
    line_term_len > 1 || line_start_len > 1 || escaped_len > 1)));

P2) Conditional jump or move depends on uninitialised value(s)
    Rows_log_event::Rows_log_event(char const*, unsigned
      int, Format_description_log_event const*) (log_event.cc:9571)

Code: Uninitialized values is reported for 'var_header_len' variable.
----
  if (var_header_len < 2 || event_len < static_cast<unsigned
      int>(var_header_len + (post_start - buf)))

P3) Conditional jump or move depends on uninitialised value(s)
    Table_map_log_event::pack_info(Protocol*) (log_event.cc:11553)

code:'m_table_id' is uninitialized.
----
  void Table_map_log_event::pack_info(Protocol *protocol)
  ...
  size_t bytes= my_snprintf(buf, sizeof(buf), "table_id: %lu (%s.%s)",
                              m_table_id, m_dbnam, m_tblnam);

Fix:
===
P1 - Fix)
Initialize cached_new_format,field_term_len, enclosed_len, line_term_len,
line_start_len, escaped_len members in default constructor.

P2 - Fix)
"var_header_len" is initialized by reading the event buffer. In case of an
invalid event the buffer will contain invalid data. Hence added a check to
validate the event data. If event_len is smaller than valid header length
return immediately.

P3 - Fix)
'm_table_id' within Table_map_log_event is initialized by reading data from
the event buffer. Use 'VALIDATE_BYTES_READ' macro to validate the current
state of the buffer. If it is invalid return immediately.

this test needs a *server* and tries to connect with $MYSQL to it

PCRE reports small frame size working with ASAN, so the test has to be ready
for the minimlas possible size.

This is the only symlink in the repository. Symlinks can cause
trouble when using file systems or operating systems that do not
support them.

Also remove the unused file DartConfig.cmake that refers to the script.

cmake -DWITH_INNODB_EXTRA_DEBUG:BOOL=ON
was broken ever since commit 8777458a
(MDEV-6076 Persistent AUTO_INCREMENT for InnoDB).

There is a race condition between page reads that call
page_zip_validate() (while holding clustered index root page S-latch)
and writes that update PAGE_ROOT_AUTO_INC
(with buf_block_t::lock SX-latch, compatible with S-latch).

page_zip_validate_low(): Skip the PAGE_ROOT_AUTO_INC field on
clustered index root pages in order to avoid false positives.

Post-push fix. aria_pack_mdev14183 test is unstable.

The fix is the following:
1. Disable the test for embedded server.
2. Create non-"transactional" Aria table in the test, as aria_pack does not
support "transactional" Aria tables.

MDEV-21249 MariaDB 10.3.10 When referring to bigint to generate timestamp data in the virtual generated column, the value of the generated column does not change when the time zone changes

FROM_UNIXTIME() depends on @@time_zone, so it's VCOL_SESSION_FUNC

Column definition order in st_maria_share::columndef can differ from
order of fields in record(see also st_maria_share::column_nr,
st_maria_columndef::column_nr, _ma_column_nr_write(),
_ma_column_nr_read()). This was not taken into account in aria_pack
tool.

The fix is to initialize elements of HUFF_COUNTS array in the correct
order.

Setting "streamfmt=mbstream" in the "[sst]" section causes SST to fail
because the format automatically switches to 'tar' by default (insead
of mbstream).

To fix this, we need to add mbstream to the list of valid values for
the format, making it synonymous with xbstream. This must be done both
in the SST script and when parsing the options of the corresponding
utilities.

Add wait conditions to make sure correct number of rows have
been replicated.

If the initialization of the wsrep provider failed, in some
cases the internal variable wrep_inited indicating that the
initialization has already been completed is still set to
"1", which then leads to confusion in the initialization
status. To solve the problem, we should set this variable
to "1" only if the wsrep provider initialization really
completed successfully.

An earlier issue has already been fixed for branch 10.4,
and this patch contains a fix for earlier versions (where
Galera 3.x is used).
