* rpl.rpl_system_versioning_partitions updated for MDEV-32188
* innodb.row_size_error_log_warnings_3 changed error for MDEV-33658

Sometimes, thread/innodb/thread_pool_thread may display
processlist_state='buffer pool load' instead of NULL
when the test is executed soon enough after server startup.
Let us suppress that information to avoid spurious failures.

All other InnoDB threads should already have been registered for

commit a2f510fccf
get_all_tables() skipped tables if the user has no privileges on
the schema itself and no granted privilege on any tables in the schema.
that is, it was skipping performance_schema tables (privileges
on them aren't explicitly granted, but internally hard-coded)
To fix:
* extend ACL_internal_table_access::check() method with
`bool any_combination_will_do`
* fix all perfschema privilege checks to take it into account.
* don't reuse table_acl_check object for all tables, initialize it
for every table otherwise GRANT_INTERNAL_INFO will leak
* remove incorrect privilege check from get_all_tables()
The test with memory restrictions randomly works or fails in buildbot
depending on server configurations. On my machine the original test
worked.
As the test was there to just check if the server crashes when run with
small memory configurations, I disabled testing if the query would fail
or not. The test still has its original purpose.
Discussed with: Sergei Golubchik <serg@mariadb.org>
The FLUSH TABLE WITH READ LOCK briefly set the state (in PROCESSLIST) to
"Waiting while replication worker thread pool is busy", even if there was
nothing to wait for. This is somewhat confusing on a server that might not
even have any replication configured, let alone replication workers.

This is a workaround patch to make buildbot green.
Renaming databases from db1/DB2 to m33020_db1/m33020_DB1
to make them unique. So the garbage left by other tests
does not show up any more.
The real problem will be fixed under terms of:
MDEV-35282 Performance schema does not clear package routines
One change is that if the port is not supplied or out of bound, the
old behaviour is to print 3306. The new behaviour is to not print
it (if not supplied) or the out of bound value.
Updated tests: cases with bugs or which cannot be run
with the cursor-protocol were excluded with
"--disable_cursor_protocol"/"--enable_cursor_protocol"
Fix for v.10.5
This commit adds 3 new status variables to 'show all slaves status':
- Master_last_event_time ; timestamp of the last event read from the
master by the IO thread.
- Slave_last_event_time ; Master timestamp of the last event committed
on the slave.
- Master_Slave_time_diff: The difference of the above two timestamps.
All the above variables are NULL until the slave has started and the
slave has read one query event from the master that changes data.
- Added information_schema.slave_status, which allows us to remove:
- show_master_info(), show_master_info_get_fields(),
send_show_master_info_data(), show_all_master_info()
- class Sql_cmd_show_slave_status.
- Protocol::store(I_List<i_string_pair>* str_list) as it is not
used anymore.
- Changed old SHOW SLAVE STATUS and SHOW ALL SLAVES STATUS to
use the SELECT code path, as all other SHOW ... STATUS commands.
Other things:
- Xid_log_time is set to time of commit to allow slave that reads the
binary log to calculate Master_last_event_time and
Slave_last_event_time.
This is needed as there is not 'exec_time' for row events.
- Fixed that Load_log_event calculates exec_time identically to
Query_event.
- Updated RESET SLAVE to reset Master/Slave_last_event_time
- Updated SQL thread's update on first transaction read-in to
only update Slave_last_event_time on group events.
- Fixed possible (unlikely) bugs in sql_show.cc ...old_format() functions
if allocation of 'field' would fail.

- FLUSH GLOBAL STATUS now resets most global_status_vars.
At this stage, this is mainly to be used for testing.
- FLUSH SESSION STATUS added as an alias for FLUSH STATUS.
- FLUSH STATUS does not require any privilege (before required RELOAD).
- FLUSH GLOBAL STATUS requires RELOAD privilege.
- All global status reset moved to FLUSH GLOBAL STATUS.
- Replication semisync status variables are now reset by
FLUSH GLOBAL STATUS.
- In test cases, the only changes are:
- Replace FLUSH STATUS with FLUSH GLOBAL STATUS
- Replace FLUSH STATUS with FLUSH STATUS; FLUSH GLOBAL STATUS.
This was only done in a few tests where the test was using SHOW STATUS
for both local and global variables.
- Uptime_since_flush_status is now always provided, independent if
ENABLED_PROFILING is enabled when compiling MariaDB.
- @@global.Uptime_since_flush_status is reset on FLUSH GLOBAL STATUS
and @@session.Uptime_since_flush_status is reset on FLUSH SESSION STATUS.
- When connected, @@session.Uptime_since_flush_status is set to 0.
MDL wait consists of short 1 second waits (this is not configurable)
repeated until lock_wait_timeout is reached. The stage is changed
to Waiting and back every second. To have predictable result in the
test the query should filter all sequences of X, "Waiting for MDL", X,
leaving just X.
On Windows systems, occurrences of ERROR_SHARING_VIOLATION due to
conflicting share modes between processes accessing the same file can
result in CreateFile failures.
mysys' my_open() already incorporates a workaround by implementing
wait/retry logic on Windows.
But this does not help if files are opened using shell redirection like
mysqltest traditionally did it, i.e via
--echo exec "some text" > output_file
In such cases, it is cmd.exe, that opens the output_file, and it
won't do any sharing-violation retries.
This commit addresses the issue by introducing a new built-in command,
'write_line', in mysqltest. This new command serves as a brief alternative
to 'write_file', with a single line output, that also resolves variables
like "exec" would.
Internally, this command will use my_open(), and therefore retry-on-error
logic.
Hopefully this will eliminate the very sporadic "can't open file because
it is used by another process" error on CI.
the value of 200 isn't enough for some tests anymore, this causes
some random threads to become not instrumented and any table operations
there are not reflected in the perfschema. If, say, a DROP TABLE
doesn't change perfschema state, perfschema tables might show
ghost tables that no longer exist in the server
