The MDEV-25004 test innodb_fts.versioning is omitted because ever since
commit 685d958e38 InnoDB would not allow
writes to a database where the redo log file ib_logfile0 is missing.
Works like vers_force but forces trx_id-based system-versioned tables
if the storage supports it (currently InnoDB-only). Otherwise creates
timestamp-based system-versioned table.
mysql_discard_or_import_tablespace(): On successful
ALTER TABLE...DISCARD TABLESPACE, evict the table handle from the
table definition cache, so that ha_innobase::close() will be invoked,
like InnoDB expects to be the case. This will avoid an assertion failure
ut_a(table->get_ref_count() == 0) during IMPORT TABLESPACE.
ha_innobase::open(): Do not issue any ER_TABLESPACE_DISCARDED warning.
Member functions for DML will do that.
ha_innobase::truncate(), ha_innobase::check_if_supported_inplace_alter():
Issue ER_TABLESPACE_DISCARDED warnings, to compensate for the removal of
the warning in ha_innobase::open().
row_quiesce_write_indexes(): Only write information about committed
indexes. The ALTER TABLE t NOWAIT ADD INDEX(c) in the nondeterministic
test case will most of the time fail due to a metadata lock (MDL) timeout
and leave behind an uncommitted index.

Like in MDEV-16110 we must release items allocated on thd->mem_root by
reopening the table.
MDEV-16290 relocated MDEV-16110 fix in 10.5 so it works for MDEV-28576
as well. 10.3 without MDEV-16290 now duplicates this fix.
Fix the regression introduced in
dfb41fddf6.
In the restructure of mysql_rm_table_no_locks the early condition
of !frm_error that enabled non_tmp_table_deleted, and hence the
query cache invalidation, was removed.
The query_cache_invalidate1(thd, dbnorm) called after
mysql_rm_table_no_locks depends on the query cache removal
(for unexamined reasons).
Under DROP DATABASE, in mysql_rm_table_no_locks, dont_log_query
is true preventing the late setting of non_tmp_table_deleted
(which retained one of its purposes as a replication deletion
of temporary tables, but not query cache invalidation).
The non_temp_tables_count however can still be used to invalidate
the query cache.
For commands
(1) alter table t1 add partition (partition p2);
(2) alter table t1 add partition (partition px history);
It printed the same error message:
Wrong partitioning type, expected type: `SYSTEM_TIME`
For (1) it is not clear from the syntax that we are trying to add
HASH partition. For (2) it is not clear that the table partitioning is
different than SYSTEM_TIME. Now it prints what type we are trying to
add to what type of partitioning.
Fixed warning unused function rename_field_in_list() for compilation
without partitioning.
The ALTER related code cannot do at the same time both:
- modify partitions
- change column data types
Explicit changing of a column data type together with a partition change is
prohibited by the parter, so this is not allowed and returns a syntax error:
ALTER TABLE t MODIFY ts BIGINT, DROP PARTITION p1;
This fix additionally disables implicit data type upgrade
(e.g. from "MariaDB 5.3 TIME" to "MySQL 5.6 TIME", or the other way
around according to the current mysql56_temporal_format) in case of
an ALTER modifying partitions, e.g.:
ALTER TABLE t DROP PARTITION p1;
In such commands now only the partition change happens, while
the data types stay unchanged.
One can additionally run:
ALTER TABLE t FORCE;
either before or after the ALTER modifying partitions to
upgrade data types according to mysql56_temporal_format.
10.5 part: test cases and comments.
The code is in the merge commit 74fe1c44aa
When f.ex. table is partitioned by HASH(a) and we rename column `a' to
`b' partitioning filter stays unchanged: HASH(a). That's the wrong
behavior.
The patch updates partitioning filter in accordance to the new columns
names. That includes partition/subpartition expression and
partition/subpartition field list.
