This should also fix the MariaDB 10.2.2 bug
MDEV-13826 CREATE FULLTEXT INDEX on encrypted table fails.
MDEV-12634 FIXME: Modify innodb-index-online, innodb-table-online
so that they will write and read merge sort files. InnoDB 5.7
introduced some optimizations to avoid using the files for small tables.
Many collation test results have been adjusted for MDEV-10191.
The problem was introduced by the patch for MDEV-7661,
which (in addition to the fix itself) included an attempt to make
CONVERT/CAST work in the same way with fields
(i.e. return NULL in strict mode if a non-convertable character found).
It appeared to be a bad idea and some users were affected by this
behavior change. Changing CONVERT/CAST not depend on sql_mode
(restoring pre-10.1.4 behavior).
* recorded new result file, original was copied from MariaDB
which produces syntactically a bit different result
* semantics are same in MariaDB and ours result file
* changed thd_binlog_format to return configured binlog format in wsrep execution,
regardless of binlogging setting (i.e. with or without binlogging)
* thd_binlog_format is used in innobase::write_row(), and would return confusing
result there when log_bin==OFF
Now we allow derived in the from clause of subqueries so set
flag which prevent optimisation of subqueries during view
creation before derived processing so subquery will be
correctly printed in the view .frm.
full server recovery is performed .
We start "mysqld" with --bootstrap
and pass bootstrap script consisting of several FLUSH TABLES FOR export/
UNLOCK TABLES
Was reported as 'rpl.rpl_gtid_stop_start fails with Valgrind in buildbot and outside'.
The 'Conditional jump or move depends on uninitialized value' valgrind complaint is valid
and means THD::m_current_stage_key that is not initialized indeed by constructor.
Fixed with its initialization added to the initializer list of
THD::THD. Double checked with mysql to have found a similar fixes for
the very same issue which was discovered after P_S merge to Maria
(60589aeee where the member is introduced) had been done.
ATTRIBUTE_NORETURN is supported on all platforms (MSVS and GCC-like).
It declares that a function will not return; instead, the thread or
the whole process will terminate.
ATTRIBUTE_COLD is supported starting with GCC 4.3. It declares that
a function is supposed to be executed rarely. Rarely used error-handling
functions and functions that emit messages to the error log should be
tagged such.
For running the Galera tests, the variable my_disable_leak_check
was set to true in order to avoid assertions due to memory leaks
at shutdown.
Some adjustments due to MDEV-13625 (merge InnoDB tests from MySQL 5.6)
were performed. The most notable behaviour changes from 10.0 and 10.1
are the following:
* innodb.innodb-table-online: adjustments for the DROP COLUMN
behaviour change (MDEV-11114, MDEV-13613)
* innodb.innodb-index-online-fk: the removal of a (1,NULL) record
from the result; originally removed in MySQL 5.7 in the
Oracle Bug #16244691 fix
377774689b
* innodb.create-index-debug: disabled due to MDEV-13680
(the MySQL Bug #77497 fix was not merged from 5.6 to 5.7.10)
* innodb.innodb-alter-autoinc: MariaDB 10.2 behaves like MySQL 5.6/5.7,
while MariaDB 10.0 and 10.1 assign different values when
auto_increment_increment or auto_increment_offset are used.
Also MySQL 5.6/5.7 exhibit different behaviour between
LGORITHM=INPLACE and ALGORITHM=COPY, so something needs to be tested
and fixed in both MariaDB 10.0 and 10.2.
* innodb.innodb-wl5980-alter: disabled because it would trigger an
InnoDB assertion failure (MDEV-13668 may need additional effort in 10.2)
with Visual Studio
simplify logic, VS generator seems to have problems if generated file
(with ADD_CUSTOM_COMMAND) depends on another generated file.
So, the fix is just to have mysqld_lib.{def,lib,exp} to be generated in a
single ADD_CUSTOM_COMMAND rather than two steps.
wsrep_drop_table_query(): Remove the definition of this ununsed function.
row_upd_sec_index_entry(), row_upd_clust_rec_by_insert():
Evaluate the simplest conditions first. The merge could have slightly
hurt performance by causing extra calls to wsrep_on().
Assertions failed due to incorrect handling of the --tc-heuristic-recover
option when InnoDB is in read-only mode either due to innodb_read_only=1
or innodb_force_recovery>3. InnoDB failed to refuse a XA COMMIT or
XA ROLLBACK operation, and there were errors in the error handling in
the upper layer.
This was fixed by making InnoDB XA operations respect the
high_level_read_only flag. The InnoDB part of the fix and
parts of the test main.tc_heuristic_recover were provided
by Marko Mäkelä.
LOCK_log mutex lock/unlock had to be added to fix MDEV-13438.
The measure is confirmed by mysql sources as well.
For testing of the conflicting option combination, mysql-test-run is
made to export a new $MYSQLD_LAST_CMD. It holds the very last value
generated by mtr.mysqld_start(). Even though the options have been
also always stored in $mysqld->{'started_opts'} there were no access
to them beyond the automatic server restart by mtr through the expect
file interface.
Effectively therefore $MYSQLD_LAST_CMD represents a more general
interface to $mysqld->{'started_opts'} which can be used in wider
scopes including server launch with incompatible options.
Notice another existing method to restart the server with incompatible
options relying on $MYSQLD_CMD is is aware of $mysqld->{'started_opts'}
(the actual options that the server is launched by mtr). In order to use
this method they would have to be provided manually.
NOTE: When merging to 10.2, the file search_pattern_in_file++.inc
should be replaced with the pre-existing search_pattern_in_file.inc.
Problem was that if column was created in alter table when
it was refered again it was not tried to find from list
of current columns.
mysql_prepare_alter_table:
There is two cases
(1) If alter table adds a new column and then later alter
changes the field definition, there was no check from
list of new columns, instead an incorrect error was given.
(2) If alter table adds a new column and then later alter
changes the default, there was no check from list of
new columns, instead an incorrect error was given.
The bug was caused by a defect of the patch for the bug 11081.
The patch was actually a port of the fix this bug from the mysql
code line. Later a correction of this fix was added to the
mysql code. Here's the comment this correction was provided with:
Bug#16499751: Opening cursor on SELECT in stored procedure causes segfault
This is a regression from the fix of bug#14740889.
The fix started using another set of expressions as the source for
the temporary table used for the materialized cursor. However,
JOIN::make_tmp_tables_info() calls setup_copy_fields() which creates
an Item_copy wrapper object on top of the function being selected.
The Item_copy objects were not properly handled by create_tmp_table -
they were simply ignored. This patch creates temporary table fields
based on the underlying item of the Item_copy objects.
The test case for the bug 13346 was taken from mdev-13380.
Merged from mysql-wsrep-bugs following:
GCF-1058 MTR test galera.MW-86 fails on repeated runs
Wait for the sync point sync.wsrep_apply_cb to be reached before
executing the test and clearing the debug flag sync.wsrep_apply_cb.
The race scenario:
Intended behavior:
node2: set sync.wsrep_apply_cb in order to start waiting in the background INSERT
node1: INSERT start
node2 (background): INSERT start
node1: INSERT end
node2: send signal to background INSERT: "stop waiting and continue executing"
node2: clear sync.wsrep_apply_cb as no longer needed
node2 (background): consume the signal
node2 (background): INSERT end
node2: DROP TABLE
node2: check no pending signals are left - ok
What happens occasionally (unexpected):
node2: set sync.wsrep_apply_cb in order to start waiting in the background INSERT
node1: INSERT start
node2 (background): INSERT start
node1: INSERT end
// The background INSERT still has _not_ reached the place where it starts
// waiting for the signal:
// DBUG_EXECUTE_IF("sync.wsrep_apply_cb", "now wait_for...");
node2: send signal to background INSERT: "stop waiting and continue executing"
node2: clear sync.wsrep_apply_cb as no longer needed
// The background INSERT reaches DBUG_EXECUTE_IF("sync.wsrep_apply_cb", ...)
// but sync.wsrep_apply_cb has already been cleared and the "wait" code is not
// executed. The signal remains unconsumed.
node2 (background): INSERT end
node2: DROP TABLE
node2: check no pending signals are left - failure, signal.wsrep_apply_cb is
pending (not consumed)
Remove MW-360 test case as it is not intended for MariaDB (uses
MySQL GTID).
collateral changes:
* remove a test from innodb_virtual_basic that is already present in
gcol_keys_innodb
* set thd->abort_on_warning for inplace alter, just like it's set
for copy_data_between_tables - to have warnings converted into
errors identically in all alter algorithms
* don't ignore errors in TABLE::update_virtual_field
doing SYSVAR_AUTOSIZE() because of back_log > max_connections
enabled "autosized" flag, and that made IS_SYSVAR_AUTOSIZE()
true, which triggered the second SYSVAR_AUTOSIZE.
Remove back_log <= max_connections limit, back_log
doesn't *always* have to be smaller than max_connections.
