pthread_equal(pthread_self(), (&(&share->intern_lock)->m_mutex)->thread)' failed in _ma_state_info_write
Length of numegic function results limited by matsimum really possible length.
(Problem was that negation did not limited it and then was not possible to create so long field)

encryption.innodb-discard-import-change fails in buildbot with valgrind
Problem was that if tablespace was encrypted we try to copy
also page 0 from read buffer to write buffer that are in
that case the same memory area.
fil_iterate
When tablespace is encrypted or compressed its
first page (i.e. page 0) is not encrypted or
compressed and there is no need to copy buffer.

If we use hostnames, it will fail during name resolution on UNIX systems

Also fix perfschema.hostcache_ipv6_max_con.
The test case makes use of a debug switch to execute some special code.
The code does hostname replacement. Every hostname sent during connect
phase becomes santa.claus.ipv4.example.com (or ipv6). This causes a
connection from root@localhost to fail, as root is not registered as
santa claus user. The failure is only apparent on Windows as Unix
systems make use of sockets, which bypass the name resolution check
entirely.

If innodb_fast_shutdown<2, all transactions of active connections
will be rolled back on shutdown. This can take a long time, and
the systemd shutdown timeout should be extended during the wait.
logs_empty_and_mark_files_at_shutdown(): Extend the timeout when
waiting for other threads to complete.

Table_open_cache gets adjusted on server startup to prevent an out of
file descriptor error. However this means that when we reset its value
to default, it does not get re-adjusted. This leads to the mtr
consistency check to fail with different server status at the end of the
test case as opposed to when it started.
To fix the problem, do not make use of the DEFAULT keyword to set the
variable back, instead save the value before any modifications and
restore it from there.

fil_crypt_read_crypt_data(): Do not attempt to read the tablespace
if the file is unaccessible due to a pending DDL operation, such as
renaming the file or DROP TABLE or TRUNCATE TABLE. This is only
reducing the probability of the race condition, not completely
preventing it.

Boost includes sys/param.h on FreeBSD, which in turn defines setbit()
macro. This macro is conflicting with open_query::judy_bitset::setbit().
Reordered includes such that oqgraph_judy.h never sees this macro.
Also removed duplicate includes of graphcore-config.h, which is included
by graphcore-graph.h/oqgraph_shim.h/oqgraph_thunk.h.

For this case we have a view that is mergeable but we are not able to merge it in the
parent select because that would exceed the maximum tables allowed in the join list, so we
materialise this view
TABLE_LIST::dervied is NULL for such views, it is only set for views which have ALGORITHM=TEMPTABLE
Fixed by making sure TABLE_LIST::derived is set for views that could not be merged

(1918):
Encountered illegal value '' when converting to DECIMAL
The issue was that EITS data was allocated but then not read for some reason (one being to avoid a deadlock),
then the optimizer was using these bzero'ed buffers as EITS statistics.
This should not be allowed, we should use statistcs for a table only when we have successfully loaded/read
the stats from the statistical tables.

The test tends to fail if many parallel instances of it are executed:
```
mysqltest: At line 23: query 'ALTER TABLE t1 ADD PRIMARY KEY (f1)' failed:
1317: Query execution was interrupted
```
The `ALTER` fails because it is BF aborted due to an earlier `INSERT SELECT`
that is being applied:
```
INSERT INTO t1 (f1) SELECT ...
--connection node_2
SET GLOBAL wsrep_desync = TRUE;
SET SESSION wsrep_on = FALSE;
ALTER TABLE t1 ADD PRIMARY KEY (f1);
SET SESSION wsrep_on = TRUE;
SET GLOBAL wsrep_desync = FALSE;
```
And because the `ALTER` is executed with `wsrep_on = OFF`, it does not
run in total order isolation.
To avoid the problem it must be ensured that the `ALTER` only after the
large `INSERT SELECT` is done. To do so it is sufficient to issue
`SELECT COUNT(*) FROM t1;` from `node_2` before turning off wsrep.
The `SELECT` will trigger `wsrep_sync_wait` and proceed only after the
`INSERT SELECT` from node_1 is done.

Problem was that key rotation from encrypted to unecrypted was skipped
when encryption is disabled (i.e. set global innodb-encrypt-tables=OFF).
fil_crypt_needs_rotation
If encryption is disabled (i.e. innodb-encrypt-tables=off)
and there is tablespaces using default encryption (e.g.
system tablespace) that are still encrypted state we need
to rotate them from encrypted state to unencrypted state.

buf_flush_remove(): Disable the output for now, because we
certainly do not want this after every page flush on shutdown.
It must be rate-limited somehow. There already is a timeout
extension for waiting the page cleaner to exit in
logs_empty_and_mark_files_at_shutdown().
log_write_up_to(): Use correct format.
srv_purge_should_exit(): Move the timeout extension to the
appropriate place, from one of the callers.

Move towards progress measures rather than pure time based measures.
Progress reporting at numberious shutdown/startup locations incuding:
* For innodb_fast_shutdown=0 trx_roll_must_shutdown() for rolling back incomplete transactions.
* For merging the change buffer (in srv_shutdown(bool ibuf_merge))
* For purging history, srv_do_purge

buf_all_freed only needs to be called once, not 3 times.
buf_all_freed will always return TRUE if it returns.
It will crash if any page was not flushed so its effectively
an assert anyway.
The following calls are likely redundant and could be removed:
fil_flush_file_spaces(FIL_TYPE_TABLESPACE);
fil_flush_file_spaces(FIL_TYPE_LOG);

row_undo_step(): If fast shutdown has been requested, abort the
rollback of any non-DDL transactions. Starting with MDEV-12323,
we aborted the rollback of recovered transactions. These
transactions would be rolled back on subsequent server startup.
trx_roll_report_progress(): Renamed from trx_roll_must_shutdown(),
now that the shutdown check has been moved to the only caller.
