"Conditional jump or move depends on uninitialised value in
my_scan_weight_utf8_general_ci, main.mysql_client_test fails in biuldbot
with valgrind"
- Fixed by ensuring that engine_name is set to empty string even in case
errors in the .frm file
- Added some error checking to ha_table_exists()
This is a 10.3 specific part of MDEV-13049.
It disables automatic sorting for
"SELECT .. FROM INFORMATION_SCHEMA.{SCHEMATA|TABLES}"
and adjusts the affected tests accordingly.
Optimizations:
* avoid faster ext_table_discovery_simple() *only* when there are
engines with discover_table_names() method *and* they look at
file names. P_S implements discover_table_names(), but it's not
a reason to use slower extension_based_table_discovery().
* don't pre-sort table names if ORDER BY or GROUP BY was specified
* starting from 10.3 only sort table names for SHOW commands
- Fix win64 pointer truncation warnings
(usually coming from misusing 0x%lx and long cast in DBUG)
- Also fix printf-format warnings
Make the above mentioned warnings fatal.
- fix pthread_join on Windows to set return value.
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)
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.
- Simplified use_trans_cache() to return at once if is_transactional is set
- Indentation and spelling errors fixed
- Don't call signal_update() if update_binlog_end_pos() is called as the
function already calls signal_update()
- Removed not used function wait_for_update_bin_log(), which would cause
errors if ever used.
- Simplified handler::clone() by always allocating 'ref' in ha_open(). To do
this I added an optional MEM_ROOT argument to ha_open() to be used when
allocating 'ref'
- Changed arguments to get_system_var() from LEX_CSTRING to LEX_CSTRING*
- Added THD as argument to create_select_for_variable(). Changed also char*
argument to LEX_CSTRING to avoid strlen() call.
- Change calls to append() to use LEX_CSTRING
- Added TABLE_SHARE->not_usable_by_query_cache
- Moved TABLE->no_replicate to TABLE_SHARE->no_replicate as it's same for
all TABLE instances
- Renamed TABLE_SHARE->cached_row_logging_check to can_do_row_logging
- Added sql/mariadb.h file that should be included first by files in sql
directory, if sql_plugin.h is not used (sql_plugin.h adds SHOW variables
that must be done before my_global.h is included)
- Removed a lot of include my_global.h from include files
- Removed include's of some files that my_global.h automatically includes
- Removed duplicated include's of my_sys.h
- Replaced include my_config.h with my_global.h
