Includes Spider patches
- 062_mariadb-10.2.0.direct_join_1and3.diff
- 063_mariadb-10.2.0.direct_join_for_single_partition.diff
- Test cases from Kentoku
Allows Spider to push full joins to the Spider engine trough the
create_group_by interface.
Other things:
- Increased MYSQL_VERSION_ID to check for 10211 (latest 10.2 version)
- Fix for const_table at calling create_group_by().
Original author: Kentoku SHIBA
Add support for direct update and direct delete requests for spider.
A direct update/delete request handles all qualified rows in a single
operation rather than one row at a time.
Contains Spiral patches:
006_mariadb-10.2.0.direct_update_rows.diff MDEV-7704
008_mariadb-10.2.0.partition_direct_update.diff MDEV-7706
010_mariadb-10.2.0.direct_update_rows2.diff MDEV-7708
011_mariadb-10.2.0.aggregate.diff MDEV-7709
027_mariadb-10.2.0.force_bulk_update.diff MDEV-7724
061_mariadb-10.2.0.mariadb-10.1.8.diff MDEV-12870
- The differences compared to the original patches:
- Most of the parameters of the new functions are unnecessary. The
unnecessary parameters have been removed.
- Changed bit positions for new handler flags upon consideration of
handler flags not needed by other Spiral patches and handler flags
merged from MySQL.
- Added info_push() (Was originally part of bulk access patch)
- Didn't include code related to handler socket
- Added HA_CAN_DIRECT_UPDATE_AND_DELETE

Contains Spiral patches:
022_mariadb-10.2.0.auto_increment.diff MDEV-7720
030: 030_mariadb-10.2.0.partition_auto_inc_init.diff MDEV-7726
These patches have the following differences compared to the original
patches:
- Added the new #defines for the feature in spd_environ.h instead of in
handler.h because these #defines are needed by Spider and are not needed
by the server.
- Cleaned up code related to the removed variable m_need_info_for_auto_inc
. Changed variable assignment in lock_auto_increment() and
unlock_auto_increment() so that the assignments are done under locks.
- Added a test case.
- Added test result changes resulting from a bug that was fixed by these
patches.

Spider patches 026 (MDEV-7723), 031 (MDEV-7727) and 058 (MDEV-12532)
This allows the storage engine to internally compute sum and count
operations.
- Enhance sum items to be able to store the sum value directly.
- return_record_by_parent() is enabled in spider as
HANDLER_HAS_DIRECT_AGGREGATE is defined
- Added spd_environ.h to spider. This is loaded first to ensure that all
MariaDB specific defines that are used by include files are properly
defined.
- This code is tested by the existing spider tests direct_aggregate.test
and direct_aggregate_part.test and also partition.test
