- Split the doublewrite test into two test (doublewrite,
doublewrite_debug) to reduce the execution time of the test
- Removed big_test tag for the newly added test case
- Made doublewrite test as non-debug test
- Added search pattern to make sure that InnoDB uses doublewrite buffer
- Replaced all kill_mysqld.inc with shutdown_mysqld.inc and
zero shutdown timeout
- Removed the case where fsp_flags got corrupted. Because from commit
3da5d047b8 (MDEV-31851) onwards,
doublewrite buffer removes the conversion the fsp flags from buggy
10.1 format

Remove ORACLE from the (session) sql_mode in connections made with sql
service to run init queries
The connection is new and the global variable value takes effect
rather than the session value from the caller of spider_db_init.
This should fix certain CI builds where the spider suite test files
and the main suite test files do not follow the same relative paths
relations as the mariadb source.
$MYSQLD_CMD uses .1 as the defaults-group-suffix, which could cause
the use of the default port (3306) or socket, which will fail in
environment where these defaults are already in use by another server.
Adding an extra --defaults-group-suffix=.1.1 does not help, because
the first flag wins.
So we use $MYSQLD_LAST_CMD instead, which uses the correct suffix.
The extra innodb buffer pool warning is irrelevant to the goal of the
test (running --wsrep-recover with --plug-load-add=ha_spider should
not cause hang)
Fix spider init bugs (MDEV-22979, MDEV-27233, MDEV-28218) while
preventing regression on old ones (MDEV-30370, MDEV-29904)
Two things are changed:
First, Spider initialisation is made fully synchronous, i.e. it no
longer happens in a background thread. Adapted from the original fix
by nayuta for MDEV-27233. This change itself would cause failure when
spider is initialised early, by plugin-load-add, due to dependency on
Aria and udf function creation, which are fixed in the second and
third parts below. Requires SQL Service, thus porting earlier versions
requires MDEV-27595
Second, if spider is initialised before udf_init(), create udf by
inserting into `mysql.func`, otherwise do it by `CREATE FUNCTION` as
usual. This change may be generalised in MDEV-31401.
Also factor out some clean-up queries from deinit_spider.inc for use
of spider init tests.
A minor caveat is that early spider initialisation will fail if the
server is bootstrapped for the first time, due to missing `mysql`
database which needs to be created by the bootstrap script.
Removing procedures that were created and dropped during init.
This also fixes a race condition where mtr test with
plugin-load-add=ha_spider.so causes post test check to fail as it
expects the procedures to still be there.
There are several plugins in ha_spider: spider, spider_alloc_mem,
spider_wrapper_protocols, spider_rewrite etc.
INSTALL PLUGIN foo SONAME ha_spider causes all the other ones to be
installed by the init queries where foo is any of the plugins.
This introduces unnecessary complexiy. For example it reads
mysql.plugins to find all other plugins, causing the hack of moving
spider plugin init to a separate thread.
To install all spider related plugins, install soname ha_spider should
be used instead.
This also fixes spurious rows in mysql.plugin when installing say only
the spider plugin with `plugin-load-add=SPIDER=ha_spider.so`:
select * from mysql.plugin;
name dl
spider_alloc_mem ha_spider.so # should not be here
spider_wrapper_protocols ha_spider.so # should not be here
Adapted from part of the reverted commit
c160a115b8.
This commit fixes a bug where IST could be rejected in favor of SST
when ssl-mode=VERIFY_CA and when mariabackup is used. It also contains
a test and small code simplifications that will make it easier to find
bugs in the future.
When QUICK_GROUP_MIN_MAX_SELECT is initialized or being reset
it stores the prefix of the last group of the index chosen for
retrieving data (last_value). Later, when looping through records
at get_next() method, the server checks whether the retrieved
group is the last, and if so, it finishes processing.
At the same time, it looks like there is no need for that additional
check since method next_prefix() returns HA_ERR_KEY_NOT_FOUND
or HA_ERR_END_OF_FILE when there are no more satisfying records.
If we do not perform the check, we do not need to retrieve and
store last_value either.
This commit removes using of last_value from QUICK_GROUP_MIN_MAX_SELECT.

Problem:
========
- InnoDB should have two keys on the same column for the self
referencing foreign key relation.
Solution:
=========
- Allow self referential foreign key relation to work with one
key.
The binlog.flashback test tries to run using the stmt and mix
binlog_format combinations (because it includes have_log_bin.inc),
yet are meaningless tests because the server starts with the
--flashback option, forcing binlog_format=row.
This patch optimizes test time by removing the stmt and mix format
combinations from running.

InnoDB could return off-by-1 estimates for the involved tables.
This would cause off-by-many difference in join output cardinality
for the top-level SELECT, and so different query plan for the subquery.
The fix: Introduce mysql-test/include/innodb_stable_estimates.{inc,opt}
which disables InnoDB's background statistics collection, and use it.
This test happens to fail if it runs after test
galera_inject_bf_long_wait.
And the reason is that galera_bf_lock_wait greps for message
"BF lock wait long" in the error log, and expects that grep matches
no lines. Whereas galera_inject_bf_long_wait intentionally causes the
message to appear in the log. The fix consists in using
assert_grep.inc with option assert_only_after, such that
galera_bf_lock_wait is limited to grep only those lines that appeared
in the log after it started to execute.

Extending the rpl_mysqldump_slave.test to incorporate the
delete-master-logs option, and this options is alias of
get binlogs: show master status -> flush logs -> purge binary logs to <new_binlog>
sequence and this test is derived using the same pattern.
also we measure the pre and post log state
on the master following the mysqldump process. Introducing
assertions to validate the correct state.
Statements affected by this bug are delete statements that have all
these conditions
1) single table delete syntax
2) and in (sub-query) predicate
3) semi-join optimization enabled
4) an order by clause.
Semijoin optimization on an innocent looking query, such as
DELETE FROM t1 WHERE c1 IN (select c2 from t2) ORDER BY c1;
turns it from a single table delete to a multi-table delete.
During multi_delete::initialize_tables for the top level join object, a
table is initialized missing a keep_current_rowid flag, needed to
position a handler for removal of the correct row after the filesort
structure has been built.

row_upd_clust_rec_by_insert(): If we are resuming from a lock wait,
reset the 'disowned' flag of the BLOB pointers in 'entry' that we
copied from 'rec' on which we had invoked btr_cur_disown_inherited_fields()
before the lock wait started. In this way, the inserted record with
the updated PRIMARY KEY value will have the BLOB ownership associated
with itself, like it is supposed to be.
Note: If the lock wait had been aborted, then rollback would have
invoked btr_cur_unmark_extern_fields() and no corruption would be possible.

ha_innobase::extra() invokes check_trx_exists() unconditionally even for
not supported operations. check_trx_exists() creates and registers trx_t
object if THD does not contain pointer to it. If ha_innobase::extra() does
not support some operation, it just invokes check_trx_exists() and quites.
If check_trx_exists() creates and registers new trx_t object for such
operation, it will never be freed and deregistered.
For example, if ha_innobase::extra() is invoked from purge thread with
operation = HA_EXTRA_IS_ATTACHED_CHILDREN, like it goes in
gcol.gcol_purge test, trx_t object will be registered, but not
deregisreted, and this causes innodb.gap_lock failure, as "SHOW ENGINE
INNODB STATUS" shows information about unexpected transaction at the end
of trx_sys.trx_list.
The fix is not to invoke check_trx_exists() for unsupported operations
in ha_innobase::extra().

It may be the case that for some reason, -Werror deprecated
for instance, that mallinfo isn't detected. In this case the
malloc.h headers won't be included which defined the mallinfo2
function and its structure.
Re-organise so that either function pulls in the header.
The problem is that background statistics can race with statistics update
during INSERT and cause slightly inaccurate `Rows` count in table statistics
(this is deliberate to avoid excessive locking overhead). This was seen as
occasional .result difference in the test.
Mask out the unstable `Rows` column from SHOW TABLE STATUS; the value is not
related to what is being tested in this part of the test case.
Run ANALYZE TABLE before SHOW EXPLAIN to get stable row count in output.

Fix some random test failures following MDEV-32168 push.
Don't blindly set $rpl_only_running_threads in many places. Instead explicit
stop only the IO or SQL thread, as appropriate. Setting it interfered with
rpl_end.inc in some cases. Rather than clearing it afterwards, better to
not set it at all when it is not needed, removing ambiguity in the test
about the state of the replication threads.
Don't fail the test if include/stop_slave_io.inc finds an error in the IO
thread after stop. Such errors can be simply because slave stop happened in
the middle of the IO thread's initial communication with the master.

Item_bool_rowready_func2, Item_func_between, Item_func_in
did not check if a not-NULL argument of an arbitrary data type
can produce a NULL value on conversion to INET6.
This caused a crash on DBUG_ASSERT() in conversion failures,
because the function returned SQL NULL for something that
has Item::maybe_null() equal to false.
Adding setting NULL-ability in such cases.
Details:
- Removing the code in Item_func::setup_args_and_comparator()
performing character set aggregation with optional narrowing.
This aggregation is done inside Arg_comparator::set_cmp_func_string().
So this code was redundant
- Removing Item_func::setup_args_and_comparator() as it git simplified to
just to two lines:
convert_const_compared_to_int_field(thd);
return cmp->set_cmp_func(thd, this, &args[0], &args[1], true);
Using these lines directly in:
- Item_bool_rowready_func2::fix_length_and_dec()
- Item_func_nullif::fix_length_and_dec()
- Adding a new virtual method:
- Type_handler::Item_bool_rowready_func2_fix_length_and_dec().
- Adding tests detecting if the data type conversion can return SQL NULL into
the following methods of Type_handler_inet6:
- Item_bool_rowready_func2_fix_length_and_dec
- Item_func_between_fix_length_and_dec
- Item_func_in_fix_comparator_compatible_types
This avoids the scenario in MDEV-32849, when the unlock happens after
the connection has been freed, say in rollback. This is done in 10.5+
after the commit a26700cca5.
It may or may not prevent potential other scenarios where spider has
locked something, then for some reason the statement needs to be
rolled back and spider frees the connection, and then spider proceeds
to use the freed connection. But at least we fix the regression
introduced by MDEV-30014 to 10.4 and bring 10.4 closer in parity with
10.5+.
Other things:
- Added DBUG_EXECUTE_IF("print_allocated_thread_memory") at end of query
to easier find not freed memory allocated by THD
- Removed free_root() from plugin_init() that did nothing.
