int wsrep_thd_append_key(THD*, const wsrep_key*, int, Wsrep_service_key_type)

CREATE TABLE [SELECT|REPLACE SELECT] is CTAS and idea was that
we force ROW format. However, it was not correctly enforced
and keys were appended before wsrep transaction was started.

At THD::decide_logging_format we should force used stmt binlog
format to ROW in CTAS case and produce a warning if used
binlog format was not ROW.

At ha_innodb::update_row we should not append keys similarly
as in ha_innodb::write_row if sql_command is SQLCOM_CREATE_TABLE.
Improved error logging on ::write_row, ::update_row and ::delete_row
if wsrep key append fails.

New runtime type diagnostic (MDEV-34490) has detected that classes
Item_func_eq, Item_default_value and Item_date_literal_for_invalid_dates
incorrectly return an instance of its ancestor classes when being cloned.
This commit fixes that.

Additionally, it fixes a bug at Item_func_case_simple::do_build_clone()
which led to an endless loop of cloning functions calls.

Reviewer: Oleksandr Byelkin <sanja@mariadb.com>

Reason:
======
- InnoDB fails to load the instant alter table metadata from
clustered index while loading the table definition.
The reason is that InnoDB metadata blob has the column length
exceeds maximum fixed length column size.

Fix:
===
- InnoDB should treat the long fixed length column as variable
length fields that needs external storage while initializing
the field map for instant alter operation

Before this patch the crash occured when a single row dataset is used and
Item::remove_eq_conds() is called for HAVING. This function is not supposed
to be called after the elimination of multiple equalities.

To fix this problem instead of Item::remove_eq_conds() Item::val_int() is
used. In this case the optimizer tries to evaluate the condition for the
single row dataset and discovers impossible HAVING immediately. So, the
execution phase is skipped.

The slave would try to sync_with_master_gtid.inc,
but the master never actually saved its gtid position
so the test would move on too quickly.

Problem:
========
- After the commit ada1074b (MDEV-14398)
fil_crypt_set_encrypt_tables() iterates through all tablespaces to
fill the default_encrypt tables list. This was a trigger to
encrypt or decrypt when key rotation age is set to 0. But import
tablespace does call fil_crypt_set_encrypt_tables() unnecessarily.
The motivation for the call is to signal the encryption threads.

Fix:
====
ha_innobase::discard_or_import_tablespace: Remove the
fil_crypt_set_encrypt_tables() and add the import tablespace
to the default encrypt list if necessary

Remove an assert added by fix for MDEV-34417. BNL-H join can be used with
prefix keys. This happens when there are real prefix indexes on the
equi-join columns (although it probably doesn't make a lot of sense).

Anyway, remove the assert. The code receives properly truncated key values
for hashing/comparison so it can handle them just fine.

- commit 85db5347 (MDEV-33400)
retains the instantness in the table definition after discard
tablespace. So there is no need to assign n_core_null_bytes
during instant table preparation unless they are not
initialized.

Statements affected by this bug need all the following to be true
1) a derived table table or view whose specification contains a set
     operation at the top level.
2) a grouping operator (group by/having) operating on a column alias
     other than in the first select of the union/intersect
3) an outer condition that will be pushed into all selects in this
     union/intersect, either into the where or having clause

When pushing a condition into all selects of a unit with more than one
select, pushdown_cond_for_derived() renames items so we can re-use the
condition being pushed.
These names need to be saved and reset for correct name resolution on
second execution of prepared statements.

We need to work around deficiencies of Valgrind, and apparently
the previous work-around attempts
(such as d247d649) do not work
anymore, definitely not on recent clang-based compilers.

MemorySanitizer should be fine; unfortunately we set HAVE_valgrind for it
as well.

It is not sufficient to check that the CPU supports the necessary
instructions. Also the operating system (or virtual machine hypervisor)
must enable all the AVX registers to be saved and restored on a
context switch.

Because clang 8 does not support the compiler intrinsic _xgetbv()
we will require clang 9 or later for enabling the use of VPCLMULQDQ
and the related AVX512 features.

Correct compatibility with view-protocol.

When there is no bounds on the upper or lower part of the window,
it doesn't matter if the type is numeric.

It also doesn't matter how many ORDER BY items there are in the
query.

New runtime diagnostic introduced with MDEV-34490 has detected
that `Item_int_with_ref` incorrectly returns an instance of its ancestor
class `Item_int`. This commit fixes that.

In addition, this commit reverts a part of the diagnostic related
to `clone_item()` checks. As it turned out, `clone_item()` is not required
to return an object of the same class as the cloned one. For example,
look at `Item_param::clone_item()`: it can return objects of `Item_null`,
`Item_int`, `Item_string`, etc, depending on the object state.
So the runtime type diagnostic is not applicable to `clone_item()` and
is disabled with this commit.

As the similar diagnostic failures are expected to appear again
in the future, this commit introduces a new test file in the main suite:
item_types.test, and new test cases may be added to this file

When mysqldump is run to dump the `mysql` system database, it generates
INSERT statements into the table `mysql.gtid_slave_pos`.
After running the backup script
those inserts did not produce the expected gtid state on slave. In
particular the maximum of mysql.gtid_slave_pos.sub_id did not make
into
   rpl_global_gtid_slave_state.last_sub_id

an in-memory object that is supposed to match the current state of the
table. And that was regardless of whether --gtid option was specified
or not. Later when the backup recipient server starts as slave
in *non-gtid* mode this desychronization may lead to a duplicate key
error.

This effect is corrected for --gtid mode mysqldump/mariadb-dump only
as the following.  The fixes ensure the insert block of the dump
script is followed with a "summing-up" SET @global.gtid_slave_pos
assignment.

For the implemenation part, note a deferred print-out of
SET-gtid_slave_pos and associated comments is prefered over relocating
of the entire blocks if (opt_master,slave_data &&
do_show_master,slave_status) ...  because of compatiblity
concern. Namely an error inside do_show_*() is handled in the new code
the same way, as early as, as before.

A regression test can be run in how-to-reproduce mode as well.
One affected mtr test observed.
rpl_mysqldump_slave.result "mismatch" shows now the new deferring print
of SET-gtid_slave_pos policy in action.

Additional tests for MDEV-28345 ASAN: use-after-poison or unknown-crash in my_strtod_int from charset_info_st::strntod or test_if_number

The test was missing a save_master_gtid.inc on the master,
leading to the slave thinking it was in sync after executing
sync_with_master_gtid.inc, despite not having executed the
latest transaction. This skipped transaction, XA COMMIT,
was supposed to error-to-be-ignored because its XID could not
be found, but be thrown out because the replication filters
would filter out the target database. However, if the slave
was able to stop before executing the transaction, then
the replication filer is reset (to empty), and when the
slave is later restarted, that transactions error would
no longer be ignored.

Additionally, as the test cases added in MDEV-33921 rely
on GTID synchronization, the test cases now force
master_use_gtid=slave_pos for consistency

This reverts commit 938b9293. Not needed after 90d376e0.

for ALTER_PARTITION_ADMIN (CHECK/REPAIR/LOAD INDEX/CACHE INDEX/etc)
partitioning marks affected partitions with PART_ADMIN state.

The assumption is that the server will call a corresponding
method of ha_partition which will reset the state back to PART_NORMAL.

This assumption is invalid, the server is not required to do so,
indeed, in CHECK ... FOR UPGRADE the server might decide early that
the table is fine and won't call ha_partition::check(), leaving
partitions in the wrong state. It will thus leak into the next
statement confusing the engine about what it is doing (see
ha_partition::create_handler_file()), causing a crash later.

Let's force all partitions into PART_NORMAL state after the admin
operation succeeded, in case it did so without consulting the engine.

There are 3 diff in result:
1) NULL value from SELECT
Due to incorrect truncating of the hex value, incorrect value is
written instead of original value to the view frm. This results in reading
incorrect value from frm, so eventual result is NULL.
2) 'Name_exp1' in column name (in gis.test)
This was because the identifier in SELECT is longer than 64 characters,
so 'Name_exp1' alias is also written to the view frm.
3)diff in explain extended
This was because the query plan for view protocol doesn't
contain database name. As a fix, disable view protocol for that particular
query.

MDEV-28345 ASAN: use-after-poison or unknown-crash in my_strtod_int from charset_info_st::strntod or test_if_number

This patch fixes two problems:

- The code inside my_strtod_int() in strings/dtoa.c could test the byte
  behind the end of the string when processing the mantissa.
  Rewriting the code to avoid this.

- The code in test_if_number() in sql/sql_analyse.cc called my_atof()
  which is unsafe and makes the called my_strtod_int() look behind
  the end of the string if the input string is not 0-terminated.
  Fixing test_if_number() to use my_strtod() instead, passing the correct
  end pointer.
