- privilege_table_io.test didn't properly reset roles_mapping
- Fixed memory allocation problem with CHECK CONSTRAINT, found when
running --valgrind main.check_constraint
* remove old 5.2+ InnoDB support for virtual columns
* enable corresponding parts of the innodb-5.7 sources
* copy corresponding test cases from 5.7
* copy detailed Alter_inplace_info::HA_ALTER_FLAGS flags from 5.7
- and more detailed detection of changes in fill_alter_inplace_info()
* more "innodb compatibility hooks" in sql_class.cc to
- create/destroy/reset a THD (used by background purge threads)
- find a prelocked table by name
- open a table (from a background purge thread)
* different from 5.7:
- new service thread "thd_destructor_proxy" to make sure all THDs are
destroyed at the correct point in time during the server shutdown
- proper opening/closing of tables for vcol evaluations in
+ FK checks (use already opened prelocked tables)
+ purge threads (open the table, MDLock it, add it to tdc, close
when not needed)
- cache open tables in vc_templ
- avoid unnecessary allocations, reuse table->record[0] and table->s->default_values
- not needed in 5.7, because it overcalculates:
+ tell the server to calculate vcols for an on-going inline ADD INDEX
+ calculate vcols for correct error messages
* update other engines (mroonga/tokudb) accordingly
* remove new InnoDB-specific ER_ and HA_ERR_ codes
* renamed few old ER_ and HA_ERR_ error messages to be less MyISAM-specific
* remove duplicate enum definitions (durability_properties, icp_result)
* move new mysql-test include files to their owner suite
* rename xtradb.rdiff files to *-disabled
* remove mistakenly committed helper perl module
* remove long obsolete handler::ha_statistic_increment() method
* restore the standard C xid_t structure to not have setters and getters
* remove xid_t::reset that was cleaning too much
* move MySQL-5.7 ER_ codes where they belong
* fir innodb to include service_wsrep.h not internal wsrep headers
* update tests and results
When a deadlock kill is detected inside the storage engine, the kill
is not done immediately, to avoid calling back into the storage engine
kill_query method with various lock subsystem mutexes held. Instead the
kill is queued and done later by a slave background thread.
This patch in preparation for fixing TokuDB optimistic parallel
replication, as well as for removing locking hacks in InnoDB/XtraDB in
10.2.

- Sometimes privilege_table_io printed double rows of roles_mapping
- Fixed by forcing restart of server when running test
- Wsrep_cluster_address_basic failed in some combinations because
wsrep_cluster_address was set to NULL
- Fixed by ensuring it's never set to NULL, only empty string
Permanently removed test case perfschema.aggregate.
The Performance Schema is generally lock-free, allowing for
race conditions that might arise from multi-threaded operation
which occasionally results in temporary and/or minor variances
when aggregating statistics. This test needs to be redesigned
to accommodate such variances.
Print default values for BLOB's.
This is a part commit for automatic changes to make the real commit smaller.
All changes here are related to that we now print DEFAULT NULL for blob and
text fields, like we do for all other fields.
Problem is that FLUSH TABLES WITH READ LOCK first blocks threads from
starting new commits, then waits for running commits to complete. But
in-order parallel replication needs commits to happen in a particular
order, so this can easily deadlock.
To fix this problem, this patch introduces a way to temporarily pause
the parallel replication worker threads. Before starting FTWRL, we let
all worker threads complete in-progress transactions, and then
wait. Then we proceed to take the global read lock. Once the lock is
obtained, we unpause the worker threads. Now commits are blocked from
starting by the global read lock, so the deadlock will no longer occur.
A few tests assumes that the CYCLE timer is always available,
which is not true on some platforms (e.g. ARM).
Fixing the tests not to reply on the CYCLE availability.
