Do not SET DEBUG_DBUG=-d,... in tests. To disable debug instrumentation,
save and restore the original value of the variable DEBUG_DBUG.
Assigning -d,... will enable the output of a lot of unrelated DBUG
messages to the server error log.
Fix and enable some of the tests; some remain disabled.
The tests innodb_gis.rtree_old and innodb_gis.row_format
duplicated some versions of the test main.gis-rtree.
Instead of duplicating, source that test, in a new test
innodb_gis.innodb_gis_rtree.
Introduce innodb_row_format.combinations. Due to this,
ROW_FORMAT=COMPRESSED will not be covered in some tests
where it is covered in MySQL 5.7.
The function rtr_update_mbr_field_in_place() is generating
MLOG_REC_UPDATE_IN_PLACE or MLOG_COMP_REC_UPDATE_IN_PLACE records
on non-leaf pages, even though MLOG_WRITE_STRING would perfectly
suffice for updating a fixed-length data field.
btr_cur_parse_update_in_place(): If flags==7, the record may be
from rtr_update_mbr_field_in_place(), and we must check if the
page is a leaf page. Otherwise, assume that it is.
btr_cur_update_in_place(): Assert that the page is a leaf page.
Some test are still disabled as they provide different results,
fail on different error or crash.
Fixes also MDEV-14060 InnoDB: Foreign key constraint to
geometry type does not work where test intentionally tried
incorrect cases.
MDEV-13851 Always check table options in ALTER TABLE…ALGORITHM=INPLACE
In the merge of MySQL 5.7.9 to MariaDB 10.2.2, some code was included
that prevents ADD SPATIAL INDEX from being executed with ALGORITHM=INPLACE.
Also, the constant ADD_SPATIAL_INDEX was introduced as an alias
to ADD_INDEX. We will remove that alias now, and properly implement
the same ADD SPATIAL INDEX restrictions as MySQL 5.7 does:
1. table-rebuilding operations are not allowed if SPATIAL INDEX survive it
2. ALTER TABLE…ADD SPATIAL INDEX…LOCK=NONE is not allowed
ha_innobase::prepare_inplace_alter_table(): If the ALTER TABLE
requires actions within InnoDB, enforce the table options (MDEV-13851).
In this way, we will keep denying ADD SPATIAL INDEX for tables
that use encryption (MDEV-11974), even if ALGORITHM=INPLACE is used.
