2db6eb1429 MDEV-22781 CREATE VIEW containing WITH clause Signal 11
For table references to CTEs the field TABLE_LIST::db must be set to
an empty string as it's done for table references to derived tables in
order CTEs to be processed similar to how derived tables are processed.

d5970779fa bugfix: mysql_create_view() infinite loop
if mysql_create_view() is aborted when view is linked into lex
(when WSREP_TO_ISOLATION_BEGIN fails),
it should not be linked there again on err:.

346d10a953 Fixed error messages from DROP VIEW to align with DROP TABLE
- Produce a "Note" for all wrongly dropped objects
  (Like doing DROP VIEW on a table).
- IF EXISTS ends with a list of all not existing objects, instead of a
  separate note for every not existing object.

Other things:
 - Fixed bug where one could do CREATE TEMPORARY SEQUENCE multiple times
   and create multiple temporary sequences with the same name.

7a947614fb Split tdc_remove_table()
TDC_RT_REMOVE_ALL -> tdc_remove_table(). Some occurrences replaced with
TDC_element::flush() (whenver TABLE_SHARE is available).

TDC_RT_REMOVE_NOT_OWN[_KEEP_SHARE] -> TDC_element::flush(). These modes
assume that current thread owns TABLE_SHARE reference, which means we can
avoid hash lookup and flush unused TABLE instances directly.

TDC_RT_REMOVE_UNUSED -> TDC_element::flush_unused(). Only [ab]used by
mysql_admin_table() currently. Should be removed eventually.

e6a50e41da MDEV-20051: Add new mode to wsrep_OSU_method in which Galera checks storage engine of the effected table
Introduced a new wsrep_strict_ddl configuration variable in which
Galera checks storage engine of the effected table. If table is not
InnoDB (only storage engine currently fully supporting Galera
replication) DDL-statement will return error code:

ER_GALERA_REPLICATION_NOT_SUPPORTED
       eng "DDL-statement is forbidden as table storage engine does not support Galera replication"

However, when wsrep_replicate_myisam=ON we allow DDL-statements to
MyISAM tables. If effected table is allowed storage engine Galera
will run normal TOI.

This new setting should be for now set globally on all
nodes in a cluster. When this setting is set following DDL-clauses
accessing tables not supporting Galera replication are refused:

* CREATE TABLE (e.g. CREATE TABLE t1(a int) engine=Aria
* ALTER TABLE
* TRUNCATE TABLE
* CREATE VIEW
* CREATE TRIGGER
* CREATE INDEX
* DROP INDEX
* RENAME TABLE
* DROP TABLE

Statements on PROCEDURE, EVENT, FUNCTION are allowed as effected
tables are known only at execution. Furthermore, USER, ROLE, SERVER,
DATABASE statements are also allowed as they do not really have
effected table.

092834cd2c Removed kill_delayed_threads_for_table()
After 7fb9d64 it is used only by ALTER/DROP SERVER, which most probably
wasn't intentional as Federated never supported delayed inserts anyway.

If delayed inserts will ever become an issue with ALTER/DROP SERVER, we
should kill them by acquiring X-lock instead.

b62101f84b Fixes for binary logging --read-only mode
- Any temporary tables created under read-only mode will never be logged
  to binary log.  Any usage of these tables to update normal tables, even
  after read-only has been disabled, will use row base logging (as the
  temporary table will not be on the slave).
- Analyze, check and repair table will not be logged in read-only mode.

Other things:
- Removed not used varaibles in
  MYSQL_BIN_LOG::flush_and_set_pending_rows_event.
- Set table_share->table_creation_was_logged for all normal tables.
- THD::binlog_query() now returns -1 if statement was not logged., This
  is used to update table_share->table_creation_was_logged.
- Don't log admin statements in opt_readonly is set.
- Table's that doesn't have table_creation_was_logged will set binlog format to row
  logging.
- Removed not needed/wrong setting of table->s->table_creation_was_logged
  in create_table_from_items()

5d510fdbf0 MDEV-18507 can't update temporary table when joined with table with triggers on read-only
triggers are opened and tables used in triggers are prelocked in
open_tables(). But multi-update can detect what tables will actually
be updated only later, after all main tables are opened.

Meaning, if a table is used in multi-update, but is not actually updated,
its on-update treggers will be opened and tables will be prelocked,
even if it's unnecessary. This can cause more tables to be
write-locked than needed, causing read_only errors, privilege errors
and lock waits.

Fix: don't open/prelock triggers unless table->updating is true.
In multi-update after setting table->updating=true, do a second
open_tables() for newly added tables, if any.

3d2d060b62 fix gcc 8 compiler warnings
There were two newly enabled warnings:
1. cast for a function pointers. Affected sql_analyse.h, mi_write.c
   and ma_write.cc, mf_iocache-t.cc, mysqlbinlog.cc, encryption.cc, etc

2. memcpy/memset of nontrivial structures. Fixed as:
* the warning disabled for InnoDB
* TABLE, TABLE_SHARE, and TABLE_LIST got a new method reset() which
  does the bzero(), which is safe for these classes, but any other
  bzero() will still cause a warning
* Table_scope_and_contents_source_st uses `TABLE_LIST *` (trivial)
  instead of `SQL_I_List<TABLE_LIST>` (not trivial) so it's safe to
  bzero now.
* added casts in debug_sync.cc and sql_select.cc (for JOIN)
* move assignment method for MDL_request instead of memcpy()
* PARTIAL_INDEX_INTERSECT_INFO::init() instead of bzero()
* remove constructor from READ_RECORD() to make it trivial
* replace some memcpy() with c++ copy assignments

a62e9a83c0 MDEV-15945 --ps-protocol does not test some queries
Make mysqltest to use --ps-protocol more

use prepared statements for everything that server supports
with the exception of CALL (for now).

Fix discovered test failures and bugs.

tests:
* PROCESSLIST shows Execute state, not Query
* SHOW STATUS increments status variables more than in text protocol
* multi-statements should be avoided (see tests with a wrong delimiter)
* performance_schema events have different names in --ps-protocol
* --enable_prepare_warnings

mysqltest.cc:
* make sure run_query_stmt() doesn't crash if there's
  no active connection (in wait_until_connected_again.inc)
* prepare all statements that server supports

protocol.h
* Protocol_discard::send_result_set_metadata() should not send
  anything to the client.

sql_acl.cc:
* extract the functionality of getting the user for SHOW GRANTS
  from check_show_access(), so that mysql_test_show_grants() could
  generate the correct column names in the prepare step

sql_class.cc:
* result->prepare() can fail, don't ignore its return value
* use correct number of decimals for EXPLAIN columns

sql_parse.cc:
* discard profiling for SHOW PROFILE. In text protocol it's done in
  prepare_schema_table(), but in --ps it is called on prepare only,
  so nothing was discarding profiling during execute.
* move the permission checking code for SHOW CREATE VIEW to
  mysqld_show_create_get_fields(), so that it would be called during
  prepare step too.
* only set sel_result when it was created here and needs to be
  destroyed in the same block. Avoid destroying lex->result.
* use the correct number of tables in check_show_access(). Saying
  "as many as possible" doesn't work when first_not_own_table isn't
  set yet.

sql_prepare.cc:
* use correct user name for SHOW GRANTS columns
* don't ignore verbose flag for SHOW SLAVE STATUS
* support preparing REVOKE ALL and ROLLBACK TO SAVEPOINT
* don't ignore errors from thd->prepare_explain_fields()
* use select_send result for sending ANALYZE and EXPLAIN, but don't
  overwrite lex->result, because it might be needed to issue execute-time
  errors (select_dumpvar - too many rows)

sql_show.cc:
* check grants for SHOW CREATE VIEW here, not in mysql_execute_command

sql_view.cc:
* use the correct function to check privileges. Old code was doing
  check_access() for thd->security_ctx, which is invoker's sctx,
  not definer's sctx. Hide various view related errors from the invoker.

sql_yacc.yy:
* initialize lex->select_lex for LOAD, otherwise it'll contain garbage
  data that happen to fail tests with views in --ps (but not otherwise).

be8709eb7b MDEV-6111 Optimizer Trace
This task involves the implementation for the optimizer trace.

This feature produces a trace for any SELECT/UPDATE/DELETE/,
which contains information about decisions taken by the optimizer during
the optimization phase (choice of table access method, various costs,
transformations, etc). This feature would help to tell why some decisions were
taken by the optimizer and why some were rejected.

Trace is session-local, controlled by the @@optimizer_trace variable.
To enable optimizer trace we need to write:
   set @@optimizer_trace variable= 'enabled=on';

To display the trace one can run:
   SELECT trace FROM INFORMATION_SCHEMA.OPTIMIZER_TRACE;

This task also involves:
    MDEV-18489: Limit the memory used by the optimizer trace
    introduces a switch optimizer_trace_max_mem_size which limits
    the memory used by the optimizer trace. This was implemented by
    Sergei Petrunia.
