The call mtr.add_suppression() that was added
in commit 75b7cd680b
for MemorySanitizer and Valgrind runs is causing
a result difference for the test rpl.rpl_gtid_stop_start.
Let us disable the binlog for executing that statement.
Also, the test perfschema.statement_program_lost_inst
would fail due to the changes to have_innodb.inc in this commit.
To compensate for that, we will make more --suite=perfschema
tests run without InnoDB, and explicitly enable InnoDB in
those tests that depend on a transactional storage engine.
A few regression tests invoke heavy flushing of the buffer pool
and may trigger warnings that tablespaces could not be deleted
because of pending writes. Those warnings are to be expected
during the execution of such tests.
The warnings are also frequently seen with Valgrind or MemorySanitizer.
For those, the global suppression in have_innodb.inc does the trick.
Added ability to disable/enable (--disable_view_protocol/--enable_view_protocol) view-protocol in tests.
When the option "--disable_view_protocol" is used util connections are closed.
Added new test for checking view-protocol
- Revert wrongly record embedded result files. These were either
recorded with normal server (not embedded) or an embedded server
with not default compile option. This can be seen that the committed
result file had replication variables which should never happen.
- Reverted back change of include/is_embedded.inc. One cannot check for
$MYSQL_EMBEDDED as this only tells if there exists an embedded
server, not if the current server we are testing is the embedded
server. This could easily be verified by doing
'mtr sys_vars.sysvars_server_embedded'. This would fail with a wrong
result instead of being marked as skipped as --embedded was not
used.
mtr is checking the wrong path for the embedded executable
on out of tree builds.
The is_embedded.inc tests are also checking the version rather
than the MTR MYSQL_EMBEDDED environment variable.
As a result, a few tests are out of date in the result recordings.
If when extracting a range condition for an index from the WHERE condition
Range Optimizer sees that the range condition covers the whole index then
such condition should be discarded because it cannot be used in any range
scan. In some cases Range Optimizer really does it, but there remained some
conditions for which it was not done. As a result the optimizer could
produce index merge plans with the full index scan for one of the indexes
participating in the index merge.
This could be observed in one of the test cases from index_merge1.inc
where a plan with index_merge_sort_union was produced and in the test case
reported for this bug where a plan with index_merge_sort_intersect was
produced. In both cases one of two index scans participating in index merge
ran over the whole index.
The patch slightly changes the original above mentioned test case from
index_merge1.inc to be able to produce an intended plan employing
index_merge_sort_union. The original query was left to show that index
merge is not used for it anymore.
It should be noted that for the plan with index_merge_sort_intersect could
be chosen for execution only due to a defect in the InnoDB code that
returns wrong estimates for the cardinality of big ranges.
This bug led to serious problems in 10.4+ where the optimization using
Rowid filters is employed (see mdev-26446).

Example build: ./BUILD/compile-pentium64-valgrind-max
Fixes:
- sp-no-valgrind failed if binary was built for valgrind as in this case
mem_root is allocated in very small hunks which the test cannot handle.
Fixed by testing of valgrind build
- truncate_notembedded failed in reap because of more memory used.
Fixed by allowing reap to fail too
Syntax for CONVERT keyword
ALTER TABLE tbl_name
[alter_option [, alter_option] ...] |
[partition_options]
partition_option: {
...
| CONVERT PARTITION partition_name TO TABLE tbl_name
}
Examples:
ALTER TABLE t1 CONVERT PARTITION p2 TO TABLE tp2;
New ALTER_PARTITION_CONVERT_OUT command for
fast_alter_partition_table() is done in alter_partition_convert_out()
function which basically does ha_rename_table().
Partition to extract is marked with the same flag as dropped
partition: PART_TO_BE_DROPPED. Note that we cannot have multiple
partitioning commands in one ALTER.
For DDL logging basically the principle is the same as for other
fast_alter_partition_table() commands. The only difference is that it
integrates late Atomic DDL functions and introduces additional phase
of WFRM_BACKUP_ORIGINAL. That is required for binlog consistency
because otherwise we could not revert back after WFRM_INSTALL_SHADOW
is done. And before DDL log is complete if we crash or fail the
altered table will be already new but binlog will miss that ALTER
command. Note that this is different from all other atomic DDL in that
it rolls back until the ddl_log_complete() is done even if everything
was done fully before the crash.
Test cases added to:
parts.alter_table \
parts.partition_debug \
versioning.partition \
atomic.alter_partition
This essentially reverts commit 4e89ec6692
and only disables InnoDB persistent statistics for tests where it is
desirable. By design, InnoDB persistent statistics will not be updated
except by ANALYZE TABLE or by STATS_AUTO_RECALC.
The internal transactions that update persistent InnoDB statistics
in background tasks (with innodb_stats_auto_recalc=ON) may cause
nondeterministic query plans or interfere with some tests that deal
with other InnoDB internals, such as the purge of transaction history.
These tests produced different results in case they were run
with the option --ps-protocol.
These tests produced different result sets since a value of
Feature_subquery and handler_read_key status system variables
are updated one time more for ps-protocol (the first time it is updated
on Prepare phase and the second time on Execute phase of PS protocol)
So different result sets are expected for both tests. To make tests
successfully runnable both for case it is run with and without
the option --ps-protocol the new protocol combination [ps, nm]
and protocol specific result files have been added.
Moreover, the perl script mysql-test/mariadb-test-run.pl
has been updated to make the variable opt_ps_protocol visible
outside perl file containing this variable.
Add fixed for tests mysqld--help,aix.rdiff and sysvars_server_notembedded,aix.rdiff
AIX couldn't compile in embedded mode so leaving sysvars_server_embedded
for later (if required).
