|| kv >= crypt_data->min_key_version,
encryption.innodb_encryption_tables failed in buildbot.
Now that key_version is not stored when page is read to
buf_page_t::key_version but always read from actual page
this assertion is not always valid.
The bug happened when the specification of a recursive CTE had
no recursive references at the top level of the specification.
In this case the regular processing of derived table references
of the select containing a non-recursive reference to this
recursive CTE misses handling the specification unit.
At the preparation stage any non-recursive reference to a
recursive CTE must be handled after the preparation of the
specification unit for this CTE. So we have to force this
preparation when regular handling of derived tables does not
do it.
This fixes a regression caused by MDEV-12428.
When we introduced a variant of fil_space_acquire() that could
increment space->n_pending_ops after space->stop_new_ops was set,
the logic of fil_check_pending_operations() was broken.
fil_space_t::n_pending_ios: A new field to track read or write
access from the buffer pool routines immediately before a block
write or after a block read in the file system.
fil_space_acquire_for_io(), fil_space_release_for_io(): Similar
to fil_space_acquire_silent() and fil_space_release(), but
modify fil_space_t::n_pending_ios instead of fil_space_t::n_pending_ops.
Adjust a number of places accordingly, and remove some redundant
tablespace lookups.
The following parts of this fix differ from the 10.2 version of this fix:
buf_page_get_corrupt(): Add a tablespace parameter.
In 10.2, we already had a two-phase process of freeing fil_space objects
(first, fil_space_detach(), then release fil_system->mutex, and finally
free the fil_space and fil_node objects).
fil_space_free_and_mutex_exit(): Renamed from fil_space_free().
Detach the tablespace from the fil_system cache, release the
fil_system->mutex, and then wait for space->n_pending_ios to reach 0,
to avoid accessing freed data in a concurrent thread.
During the wait, future calls to fil_space_acquire_for_io() will
not find this tablespace, and the count can only be decremented to 0,
at which point it is safe to free the objects.
fil_node_free_part1(), fil_node_free_part2(): Refactored from
fil_node_free().
This fixes a regression caused by MDEV-12428.

FIXME: buf_page_check_corrupt() should take a tablespace from
fil_space_acquire_for_io() as a parameter. This will be done
in the 10.1 version of this patch and merged from there.
That depends on MDEV-12253, which has not been merged from 10.1 yet.

These changes are comparable to Percona's modifications in innodb in the
Percona Xtrabackup repository.
- If functions are used in backup as well as in innodb, make them non-static.
- Define IS_XTRABACKUP() macro for special handling of innodb running
inside backup.
- Extend some functions for backup.
fil_space_for_table_exists_in_mem() gets additional parameter
'remove_from_data_dict_if_does_not_exist', for partial backups
fil_load_single_table_tablespaces() gets an optional parameter predicate
which tells whether to load tablespace based on database or table name,
also for partial backups.
srv_undo_tablespaces_init() gets an optional parameter 'backup_mode'
- Allow single redo log file (for backup "prepare")
- Do not read doublewrite buffer pages in backup, they are outdated
- Add function fil_remove_invalid_table_from_data_dict(), to remove non-existing
tables from data dictionary in case of partial backups.
- On Windows, fix file share modes when opening tablespaces,
to allow mariabackup to read tablespaces while server is online.
- Avoid access to THDVARs in backup, because innodb plugin is not loaded,
and THDVAR would crash in this case.
- Backup will load encryption plugins outside of mysqld. Thus, do not
force loading MyISAM plugin in plugin_load.
- init_signals() will be used in backup, make it global, not static.
- Do not throw output of exec command, if disable_result_log is set
save and dump it if exec fails. Need tha to meaningfully analyze
errors from mariabackup.
- rmdir now removes the entire tree. need that because xtrabackup tests
clean the whole directory.
- all filesystem modifying commands now require the argument to
be under MYSQLTEST_VARDIR or MYSQL_TMP_DIR.
Do not exporting mysqld entry points directly.
This is needed for mariabackup, to load encryption plugins on Windows.
All plugins are "pure" by default. To mark plugin "impure"
it should use RECOMPILE_FOR_EMBEDDED or STORAGE_ENGINE keyword.
because mysql->net.thd was reset to NULL in mysql_real_connect()
and thd_increment_bytes_received() didn't do anything.
Fix:
* set mysql->net.thd to current_thd instread.
* remove the test for non-null THD from a very often used
function thd_increment_bytes_received().
On several buildbot machines, the test fails like this:
CURRENT_TEST: wsrep.binlog_format
mysqltest: At line 12: query 'SET binlog_format=STATEMENT' failed:
1231: Variable 'binlog_format' can't be set to the value of 'STATEMENT'
ANALYSIS
This is regression caused due to worklog 6742 which
implemented ha_innobase::records() which always
uses clustered index to get the row count. Previously
optimizer chose secondary index which was smaller in
size of clustered index to scan for rows and resulted in
a quicker scan.
FIX
After discussion it was decided to remove this feature in 5.7.

- Allow the server to start if innodb force recovery is set to 6
even though change buffer is not empty
Reviewed-by: Jimmy Yang <jimmy.yang@oracle.com>
Problem:
========
- Drop table assert if innodb_force_recovery is set to 5 or 6.
For innodb_force_recovery 5 and 6, InnoDB doesn't scan the undo log
and it makes the redo rollback segment as NULL. There is no way for
transaction to write any undo log.
- If innodb_force_recovery is set to 6 then InnoDB does not do the
redo log roll-forward in connection with recovery. In this case,
log_sys will be initalized only and it will not have latest
checkpoint information. Checkpoint is done during shutdown even
innodb_force_recovery is set to 6. So it leads to incorrect
information update in checkpoint header.
Solution:
========
1) Allow drop table only if innodb_force_recovery < 5.
2) Make innodb as read-only if innodb_force_recovery is set to 6.
3) During shutdown, remove the checkpoint if innodb_force_recovery
is set to 6.
