Relax the number-of-XA-engines check on recovery. Allow *more*
engines to be present than absolutely necessary, extra engines
cannot affect ACID guarantees of the recovery process.
As a bonus, 10.0->crash->10.1 upgrade won't complain about
wsrep being a new XA storge engine.
plugin_init() works like this:
1. init MyISAM
2. load plugins from mysql.plugin, if it's a MyISAM table
3. init all not initialized plugins
4. all done, if step 2 loaded mysql.plugin,
otherwise:
5. load plugins from mysql.plugin
6. init all not initialized plugins
now, with --help --verbose, step 3 will not actually
initialize them, and if mysql.plugin is unreadable,
step 6 will try to initialize existing plugins again.
Fix: when skipping initialization because of --help,
change plugin status from PLUGIN_IS_UNINITIALIZED.
Analysis: We have reserved ROW_MERGE_RESERVE_SIZE ( = 4) for
encryption key_version. When calculating is there more
space on sort buffer, this value needs to be substracted
from current available space.
MDEV-8923: port innodb_buffer_pool_dump_pct from MySQL
WL#6504 InnoDB buffer pool dump/load enchantments
This patch consists of two parts:
1. Dump only the hottest N% of the buffer pool(s)
2. Prevent hogging the server duing BP load
From MySQL - commit b409342c43ce2edb68807100a77001367c7e6b8e
Add testcases for innodb_buffer_pool_dump_pct.
Part of the code authored by Daniel Black.
- Make accelerated checksum available to InnoDB and XtraDB.
- Fall back to slice-by-eight if not available. The mode used is printed on startup.
- Will only build on POWER systems at the moment until CMakeLists are modified
to only add the crc32_power8/ files when building on POWER.

- Added missning setting of table->rpl_write_set in record_gtid(), required by galera
- Removed output of WSREP_PATCH_VERSION from galera_defaults, as this can change over time
- Limit galera_many_tables_pk and galera_many_tables_nopk to 900, as
on many systems the default open table limit is 1024
Always return NULL on error.
Adding also the file length.

- JSONCOL::WriteColumn Add types SHORT and BIGINT as accepted
modified: storage/connect/tabjson.cpp
- TDBJSN: Make this type use a separate storage for Json parsing
and retrieve this memory between each rows. This is necessary
to be able to handle big tables. See MDEV-9228.

Avoid calling the wrong AddValue (Windows compiler error ???)
modified: storage/connect/json.h
Fix looping bug in JARRAY::AddValue for arrays having one value.
Fix potential crash in JVALUE::SetValue
modified: storage/connect/json.cpp
Many changes to fix bugs, enhance memory handling and modify Jpath.
In JSNX some functions have been re-written or added to handle new Jpath.
BMX was re-defined to avoid a different size between Windows an Linux.
Jbin memory was fixed to use the proper memory when adding values.
Default pretty value is now 0 instead of 2.
Filename is stored in BSON when IsJson == 2.
BSON size is added to memlen in CalcLen when applicable.
The order or parameter was switch in Json_Object_Grp.
File name argument must be a constant (temporary?)
Json_Set_Item now returns file name when applicable.

myisam_recover is only an alias for myisam_recover_options.
Use the option name instead of the alias is more correct.
This also avoids an note about the use of an alias instead of the option
name on every server start.
WL#6504 InnoDB buffer pool dump/load enchantments
This patch consists of two parts:
1. Dump only the hottest N% of the buffer pool(s)
2. Prevent hogging the server duing BP load
From MySQL - commit b409342c43ce2edb68807100a77001367c7e6b8e
Post-fix: The test case pushed with the fix had each node
acting as slave to the other two nodes with different set
of filters on server_id's. The slave's gtid_slave_pos is
updated after it processes the events received from master
nodes irrespective of whether the events were filtered
or not. Thus, sync_with_master_gtid.inc could unblock even
on filtered events.
As a result, sync_with_master_gtid.inc would fail to block
until the desired changes have been replicated. Fixed by
simplifying the topology.
Also, modified CHANGE MASTER commands to ignore based
on gtid_domain_id instead of server_id.
Provided IBM System Z have outdated compiler version, which supports gcc sync
builtins but not gcc atomic builtins. It also has weak memory model.
InnoDB attempted to verify if __sync_lock_test_and_set() is available by
checking IB_STRONG_MEMORY_MODEL. This macro has nothing to do with availability
of __sync_lock_test_and_set(), the right one is HAVE_ATOMIC_BUILTINS.
thread_pool_size is auto-sized before my_getopt(). But my_getopt starts from
resetting all options to their default values. So the auto-sized value is lost.
Fixed by moving thread_pool_size auto-sizing after my_getopt().
