recv_apply_hashed_log_recs(): Change the return type back to void
(DB_SUCCESS was always returned).
Report progress also via systemd using sd_notifyf().
Also, implement MDEV-11027 a little differently from 5.5:
recv_sys_t::report(ib_time_t): Determine whether progress should
be reported.
recv_apply_hashed_log_recs(): Rename the parameter to last_batch.
Revoked executable bit from files that are not supposed to be executed directly.
Removed interpreted from files that are not supposed to be executed directly.
Added interpreter to files that are supposed to be executed directly.
Problem: integer literals may be converted to floats for
comparison with decimal data. If the integers are large,
we may lose precision, and give wrong results.
Fix: for
<non-const decimal expression> <cmp> <const string expression>
or
<const string expression> <cmp> <non-const decimal expression>
we override the compare_type chosen by item_cmp_type(), and
do comparison as decimal rather than float.

my_readline can fail due to missing file. Make my_readline report this
condition separately so that we can catch it and report an appropriate
error message to the user.
This is an addition to original fix. Buildbot revealed another sporadic failure
in perfschema.threads_mysql test. Tests relies on data stored in
performance_schema.threads, while performing waits on
information_schema.processlist. These tables are not updated synchronously.
Fixed by performing waits on performance_schema.threads instead.
This removes functionality of where ./mtr --mem /tmp/dir could be a directory.
Now MTR_MEM=/tmp/dir ./mtr is needed.
The case where MTR_MEM=/tmp/dir ./mtr --mem has the equivalent effect.

--mem works better as a pure flag, because it can be followed by command-line arguments (test names). If the option is allowed to have a value, the test name which directly follows it will be treated as the option value instead. It is possible to implement workarounds to avoid this, but they would not be completely reliable, and there is no practical purpose of such extension of functionality to justify them.
The function mysql_derived_merge() erroneously did not mark newly formed
AND formulas in ON conditions with the flag abort_on_null. As a result
not_null_tables() calculated incorrectly for these conditions. This
could prevent conversion of embedded outer joins into inner joins.
Changed a test case from table_elim.test to preserve the former execution
plan.

Bug#12766319 - 61865: RENAME USER DOES NOT WORK CORRECTLY -
REQUIRES FLUSH PRIVILEGES
FUNCTIONS/PRIVILEGES DIFFERENTLY'.
The problem was that attempt to grant EXECUTE or ALTER
ROUTINE privilege on stored procedure which didn't exist
succeed instead of returning an appropriate error like
it happens in similar situation for stored functions or
tables.
The code which handles granting of privileges on individual
routine calls sp_exist_routines() function to check if routine
exists and assumes that the 3rd parameter of the latter
specifies whether it should check for existence of stored
procedure or function. In practice, this parameter had
completely different meaning and, as result, this check was
not done properly for stored procedures.
This fix addresses this problem by bringing sp_exist_routines()
signature and code in line with expectation of its caller.
TOCTOU bug. The path is checked to be valid, symlinks are resolved.
Then the resolved path is opened. Between the check and the open,
there's a window when one can replace some path component with a
symlink, bypassing validity checks.
Fix: after we resolved all symlinks in the path, don't allow open()
to resolve symlinks, there should be none.
Compared to the old MyISAM/Aria code:
* fastpath. Opening of not-symlinked files is just one open(),
no fn_format() and lstat() anymore.
* opening of symlinked tables doesn't do fn_format() and lstat() either.
it also doesn't to realpath() (which was lstat-ing every path
component), instead if opens every path component with O_PATH.
* share->data_file_name stores realpath(path) not readlink(path). So,
SHOW CREATE TABLE needs to do lstat/readlink() now (see ::info()),
and certain error messages (cannot open file "XXX") show the real
file path with all symlinks resolved.
Workaround for join_cache + index on vcols + keyread bug.
Initialize the record to avoid caching garbage in non-read fields.
A proper fix (do not cache non-read fields at all) is done in 10.2
in commits 5d7607f340f..8d99166c697
'Not exists' optimization can be used for nested outer joins
only if IS NULL predicate from the WHERE condition is activated.
So we have to check that all guards that wrap this predicate
are in the 'open' state.
This patch supports usage of 'Not exists' optimization for any
outer join, no matter how it's nested in other outer joins.
This patch is also considered as a proper fix for bugs
#49322/#58490 and LP #817360.
SPORADICALLY ON PB2-5.5 FOR LINUX-VALGRIND
Description: Sporadic failure of variables-bug21503595 test
on pb2-5.5 for linux-valgrind platform.
Fix: This is a issue related to libc and not related to
MySQL code. During dlclose few blocks of memory left
unfreed. This is a known issue in libc and needs to be
suppressed.
Fix: Added a valgrind suppression.
Problem: CREATE TABLE using a fully qualified name with INDEX DIR/DATA DIR
option reports an error when the current database is not SET.
check_access() was incorrectly called with NULL as the database
argument in a situation where the database name was not needed for
the particular privilege being checked. This will cause the current
database to be used, or an error to be reported if there is no current
database.
Fix: Call check_access() with any_db as the database argument in this situation.
(with blocks are still reachable).
There was a similar suppression already, but it had an extra line
comparing to failures which we are getting, so it wasn't applied.
Added another variant of the suppression.
Problem:- When MariaDB is compiled with jemalloc support, And we run mtr valgrind
test, valgrind interferes with libjemalloc and returns false errors.
Solution:- Run valgrind with --soname-synonyms=somalloc=libjemalloc* or
--soname-synonyms=somalloc=NONE depending on whether we are dynamically
linking or statically linking.

The failure happens due to a race condition between processing
a row event (INSERT) and an automatically generated event
DROP TEMPORARY TABLE. Even though DROP has a higher GTID, it can
become visible in @@gtid_slave_pos before the row event with
a lower GTID has been committed. Since the test makes the slave
to synchronize with the master using GTID, the waiting stops
as soon as GTID of the DROP TEMPORARY TABLE becomes visible,
and if changes from the previous event haven't been applied yet,
the error occurs.
According to Kristian (see the comment to MDEV-10631), the real
problem is that DROP TEMPORARY TABLE is logged in the row mode
at all. For this particular test, since DROP does not do anything,
nothing prevents it from competing with the prior transaction.
The workaround for the test is to add a meaningful event
after DROP TEMPORARY TABLE, so that the slave would wait on its
GTID instead of the one from DROP.
Additionally (unrelated to this problem) removed FLUSH TABLES,
which, as the comment stated, should have been removed after
MDEV-6403 was fixed.
The standalone warning is not a sign of a problem, just of slowness,
so it should be added to global suppressions. If a real problem
happens, there will be other errors
* Revert "Make --mem a pure flag. If there is need to specifically set the location"
This reverts commit 716621db3f.
* MDEV-11619: mtr: when --mem is pure flag, conflicts with $MTR_MEM
Conflicts occurs when MTR_MEM=/xxx/yy ./mtr --mem is invoked. Here
the --mem option overrides opt_mem leaving the default path to be chosen.
This change makes when MTR_MEM set, opt_mem, the flag, is also
set. Both the environment and flag can no be set without conflicting.

* MDEV-11619: if opt_mem is a path include it first
* MDEV-11619: MTR_MEM locations - don't follow symlinks
From Bjorn Munch it seems symlinks can confuse some
tests. Lets just avoid those.

parts.partition_float_myisam, parts.partition_int_myisam,
parts.partition_float_innodb are all known to fail with timeouts
on slow builders. The tests are composed of several independent parts
for corresponding subtypes (float == float + double,
int == tinyint + smallint + mediumint + int + bigint). The solution
is to split them into separate tests. No test logic has been changed.
This patch is actually a complement for the fix of bug mdev-6892.
The procedure create_tmp_table() now must take into account
Item_direct_refs that wrap up constant fields of derived tables/views
that are used as inner tables in outer join operations.
On a slow builder, a delay between binlog events on master could
occur, which would cause a heartbeat which is not expected by the
test. The solution is to monitor the timing of binlog events
on the master and only perform the heartbeat check if no critical
delays have happened.
Additionally, an unused variable was removed (this change is
unrelated to the bugfix).
Test results are distorted by a small rounding error
during an intermediate stage of calculating the result.
By using the SQL ROUND function we stablise tests.
