Correct used configuration and force server restarts before test
case. Add wait condition instead of sleep to verify that
all expected nodes are back to cluster.

rpl.rpl_seconds_behind_master_spike uses the DEBUG_SYNC mechanism to
count how many format descriptor events (FDEs) have been executed,
to attempt to pause on a specific relay log FDE after executing
transactions. However, depending on when the IO thread is stopped,
it can send an extra FDE before sending the transactions, forcing
the test to pause before executing any transactions, resulting in a
table not existing, that is attempted to be read for COUNT.

This patch fixes this by no longer counting FDEs, but rather by
programmatically waiting until the SQL thread has executed the
transaction and then automatically activating the DEBUG_SYNC point
to trigger at the next relay log FDE.

Problem was that if wsrep_load_data_splitting was used
streaming replication (SR) parameters were set
for MyISAM table. Galera does not currently support SR for
MyISAM.

Fix is to ignore wsrep_load_data_splitting setting (with
warning) if table is not InnoDB table.

This is 10.4-10.5 case of fix.

Problem is that Galera starts TOI (total order isolation) i.e.
it sends query to all nodes. Later it is discovered that
used engine or other feature is not supported by Galera.
Because TOI is executed parallelly in all nodes appliers
could execute given TOI and ignore the error and
start inconsistency voting causing node to leave from
cluster or we might have a crash as reported.

For example SEQUENCE engine does not support GEOMETRY data
type causing either inconsistency between nodes (because
some errors are ignored on applier) or crash.

Fixed my adding new function wsrep_check_support to check
can Galera support provided CREATE TABLE/SEQUENCE before TOI is
started and if not clear error message is provided to
the user.

Currently, not supported cases:

* CREATE TABLE ... AS SELECT when streaming replication is used
* CREATE TABLE ... WITH SYSTEM VERSIONING AS SELECT
* CREATE TABLE ... ENGINE=SEQUENCE
* CREATE SEQUENCE ... ENGINE!=InnoDB
* ALTER TABLE t ... ENGINE!=InnoDB where table t is SEQUENCE

Problem was that REPLACE was using consistency check that started
TOI and we tried to rollback it.

Do not use wsrep_before_rollback and wsrep_after_rollback if
we are runing consistency check because no writeset keys are
in that case added. Do not allow consistency check usage
if table storage for target table is not InnoDB, instead
give warning. REPLACE|SELECT INTO ... SELECT will use
now TOI if table storage for target table is not InnoDB
to maintain consistency between galera nodes.

A debug_sync signal could remain for the SQL thread that should have begun
a wait_for upon seeing a GTID event, but would instead see the old signal
and continue on without waiting. This broke an "idle" condition in
SHOW SLAVE STATUS
which should have automatically negated Seconds_Behind_Master. Instead,
because the SQL thread had already processed the GTID event, it set
sql_thread_caught_up to false, and thereby calculated the value of
Seconds_behind_master, when the test expected 0.

This patch fixes this by resetting the debug_sync state before creating a
new transaction which sends a GTID event to the replica

With this patch, 4-component MSI version can be used, e.g by setting
TINY_VERSION variable in CMake, or by adding a string, e.g
MYSQL_VERSION_EXTRA=-2
which sets TINY_VERSION to 2, and also changes the package name.

The 4-component MSI versions do not support MSI major upgrades, only minor
ones, i.e do not reinstall components, just update existing ones based
on versioning rules.

To support these rules, add DefaultVersion for the files that won't
otherwise be versioned - headers, static and import libraries,
pdbs, text - xml, python and perl scripts Also silence WiX warning
that MSI won't store hashes for those files anymore.

There are two array fields in spider_share with similar names:

share->use_sql_dbton_ids that maps from i to the i-th dbton used by
share. Thus it should be used only when i iterates over all distinct
dbtons used by share.

share->sql_dbton_ids that maps from i to the dbton used by the i-th
link of the share. Thus it should be used only when i iterates over
all links of a share.

We correct instances where share->sql_dbton_ids should be used instead
of share->use_sql_dbton_ids.

Turning REGEXP_REPLACE into two schema-qualified functions:
- mariadb_schema.regexp_replace()
- oracle_schema.regexp_replace()

Fixing oracle_schema.regexp_replace(subj,pattern,replacement) to treat
NULL in "replacement" as an empty string.

Adding new classes implementing oracle_schema.regexp_replace():
- Item_func_regexp_replace_oracle
- Create_func_regexp_replace_oracle

Adding helper methods:
- String *Item::val_str_null_to_empty(String *to)
- String *Item::val_str_null_to_empty(String *to, bool null_to_empty)

and reusing these methods in both Item_func_replace and
Item_func_regexp_replace.

When CMAKE_OSX_ARCHITECTURES isn't set we end up with
"Packaging as: mariadb-10.4.33-osx10.19-x86_64" on arm64 builders.

Instead of implying 64bit is x86, use CMAKE_SYSTEM_PROCESSOR to form
the filename.

More in depth check to cover all used readline functions.

Undo any Windows behaviour changes.

While a replica may be reading events from the
primary, the primary is killed. Left to its own
devices, the IO thread may or may not stop in
error, depending on what it is doing when its
connection to the primary is killed (e.g. a
failed read results in an error, whereas if the
IO thread is idly waiting for events when the
connection dies, it will enter into a reconnect
loop and reconnect). MDEV-32168 changed the test
to always wait for the reconnect, thus breaking
the error case, as the IO thread would be stopped
at a time of expecting it to be running.

The fix is to manually stop/start the IO thread
to ensure it is in a consistent state.

Note that rpl_domain_id_filter_master_crash.test
will need additional changes after fixing MDEV-33268

This patch introduces the following behaviour for Linux while
maintaining old behaviour for Windows:

Ctrl + C (sigint) clears the current buffer and redraws the prompt.
Ctrl-C no longer exits the client if no query is running.
Ctrl-C kills the current running query if there is one. If there is an
error communicating with the server while trying to issue a KILL QUERY,
the client exits. This is in line with the past behaviour of Ctrl-C.
On Linux Ctrl-D can be used to close the client.
On Windows Ctrl-C and Ctrl-BREAK still exits the client if no query is running.
Windows can also exit the client via \q<enter> or exit<enter>.

== Implementation details ==
The Linux implementation has two corner cases, based on which library is
used: libreadline or libedit, both are handled in code to achieve the
same user experience.

Additional code is taken from MySQL, ensuring there is identical
behaviour on Windows, to MySQL's mysql client implementation for other
CTRL- related signals.

* The CTRL_CLOSE, CTRL_LOGOFF, CTRL_SHUTDOWN will issue the equivalent
  of CTRL-C and "end" the program. This ensures that the query is killed
  when the client is closed by closing the terminal, logging off the
  user or shutting down the system. The latter two signals are not sent
  for interactive applications, but it handles the case when a user has
  defined a service to use mysql client to issue a command. See
  https://learn.microsoft.com/en-us/windows/console/handlerroutine

This patch is built on top of the initial work done by Anel Husakovic
<anel@mariadb.org>.
Closes #2815

Modified `federatedx_io_mysql::actual_query` to set the time zone to '+00:00' only upon establishing a new connection instead of with each query execution.

This patch corrects the fix for MDEV-32569. The latter has not taken into
account the fact not each statement uses the SELECT_LEX structure. In
particular CALL statements do not use such structure. However the parameter
passed to the stored procedure used in such a statement may require an
invocation of Type_std_attributes::agg_item_set_converter().

os_file_set_size(): Let us invoke the Linux system call fallocate(2)
directly, because the GNU libc posix_fallocate() implements a fallback
that writes to the file 1 byte every 4096 or fewer bytes. In one
environment, invoking fallocate() directly would lead to 4 times the
file growth rate during ALTER TABLE. Presumably, what happened was
that the NFS server used a smaller allocation block size than 4096 bytes
and therefore created a heavily fragmented sparse file when
posix_fallocate() was used. For example, extending a file by 4 MiB
would create 1,024 file fragments. When the file is actually being
written to with data, it would be "unsparsed".

The built-in EOPNOTSUPP fallback in os_file_set_size() writes a buffer
of 1 MiB of NUL bytes. This was always used on musl libc and other
Linux implementations of posix_fallocate().

Modify the NS_ZERO state in the JSON number parser to allow
exponential notation with a zero coefficient (e.g. 0E-4).

The NS_ZERO state transition on 'E' was updated to move to the
NS_EX state rather than returning a syntax error. Similar change
was made for the NS_ZE1 (negative zero) starter state.

This allows accepted number grammar to include cases like:

- 0E4
- -0E-10

which were previously disallowed. Numeric parsing remains
the same for all other states.

Test cases are added to func_json.test to validate parsing for
various exponential numbers starting with zero coefficients.

When the host is not specified, it defaults to localhost.

A new column was introduced to the show index output in 10.6 in
f691d986

Thus we update the check of the number of columns to be at least 13,
rather than exactly 13.

Also backport an err number and format from 10.5 for better error
messages when the column number is wrong.

There are a large number of uses of `strerror` in the codebase,
the local declaration in `storage/connect/tabvct.cpp` is the only one.

Given that none is needed elsewhere, I conclude that this instance can
simply be removed.

initialize THD::rand in THD::init() not in THD::THD(),
because the former is also called when a THD is reused -
in COM_CHANGE_USER and in taking a THD from the cache.

Also use current cycle timer for more unpreditability

Item_float::neg() did not preserve the "presentation" from "this".
So
  CAST(-1e0 AS UNSIGNED)  -- cast from double to unsigned
changes its meaning to:
  CAST(-1 AS UNSIGNED)  -- cast signed to undigned

Fixing Item_float::neg() to construct the new value for
Item_float::presentation as follows:
- if the old value starts with minus, then the minus is truncated:
  '-2e0' -> '2e0'
- otherwise, minus sign followed by its old value:
  '1e0'  -> '-1e0'

The bitmap is temporarily flipped to ~0 for the sake of checking all
fields. It needs to be restored because it will be reused in second
and subsequent ps execution.
