This imports and adapts a number of MySQL 5.7 test cases that are
applicable to MariaDB.
Some tests for old bug fixes are not that relevant because the code
has been refactored since then (especially starting with
MariaDB Server 10.6), and the tests would not reproduce the
original bug if the fix was reverted.
In the test innodb_fts.opt, there are many duplicate MATCH ranks, which
would make the results nondeterministic. The test was stabilized by
changing some LIMIT clauses or by adding sorted_result in those cases
where the purpose of a test was to show that no sorting took place
in the server.
In the test innodb_fts.phrase, MySQL 5.7 would generate FTS_DOC_ID that
are 1 larger than in MariaDB. In innodb_fts.index_table the difference is 2.
This is because in MariaDB, fts_get_next_doc_id() post-increments
cache->next_doc_id, while MySQL 5.7 pre-increments it.

In my merge of the MySQL fix for Oracle Bug#23333990 / WL#9513
I overlooked some subsequent revisions to the test, and I also
failed to notice that the test is actually always failing.
Oracle introduced the parameter innodb_stats_include_delete_marked
but failed to consistently take it into account in FOREIGN KEY
constraints that involve CASCADE or SET NULL.
When innodb_stats_include_delete_marked=ON, obviously the purge of
delete-marked records should update the statistics as well.
One more omission was that statistics were never updated on ROLLBACK.
We are fixing that as well, properly taking into account the
parameter innodb_stats_include_delete_marked.
dict_stats_analyze_index_level(): Simplify an expression.
(Using the ternary operator with a constant operand is unnecessary
obfuscation.)
page_scan_method_t: Revert the change done by Oracle. Instead,
examine srv_stats_include_delete_marked directly where it is needed.
dict_stats_update_if_needed(): Renamed from
row_update_statistics_if_needed().
row_update_for_mysql_using_upd_graph(): Assert that the table statistics
are initialized, as guaranteed by ha_innobase::open(). Update the
statistics in a consistent way, both for FOREIGN KEY triggers and
for the main table. If FOREIGN KEY constraints exist, do not dereference
a freed pointer, but cache the proper value of node->is_delete so that
it matches prebuilt->table.
row_purge_record_func(): Update statistics if
innodb_stats_include_delete_marked=ON.
row_undo_ins(): Update statistics (on ROLLBACK of a fresh INSERT).
This is independent of the parameter; the record is not delete-marked.
row_undo_mod(): Update statistics on the ROLLBACK of updating key columns,
or (if innodb_stats_include_delete_marked=OFF) updating delete-marks.
innodb.innodb_stats_persistent: Renamed and extended from
innodb.innodb_stats_del_mark. Reduced the unnecessarily large dataset
from 262,144 to 32 rows. Test both values of the configuration
parameter innodb_stats_include_delete_marked.
Test that purge is updating the statistics.
innodb_fts.innodb_fts_multiple_index: Adjust the result. The test
is performing a ROLLBACK of an INSERT, which now affects the statistics.
include/wait_all_purged.inc: Moved from innodb.innodb_truncate_debug
to its own file.
