--gdb now accepts an argument, it will be passed to gdb as a command.
multiple commands can be separated by a (non-standard and not escapable)
delimiter - semicolon (;).
Old usage with a bare --gdb continues to work too, of course.
MDEV--15609 engines/funcs.crash_manytables_number crashes with error 24
(too many open files)
MDEV-10286 Adjustment of table_open_cache according to system limits
does not work when open-files-limit option is provided
Fixed by adjusting tc_size downwards if there is not enough file
descriptors to use.
Other changes:
- Ensure that there is 30 (was 10) extra file descriptors for other usage
- Decrease TABLE_OPEN_CACHE_MIN to 200 as it's better to have a smaller
table cache than getting error 24
- Increase minimum of max_connections and table_open_cache from 1 to 10
as 1 is not usable for any real application, only for testing.
If a mtr test case has started two mysqld processes (replication tests),
then kills the first one and kills the second one before starting the
first (so at some point there are two mysqlds down), then the ./mtr
waiting process bricks and forgets to monitor the "expect" file of the
first mysqld, so it never gets started again, even when its contents is
changed to "restart".
A victim of this deficiency is at least galera.galera_gcache_recover.
The fix is to keep a list of all mysqlds we should wait to start, not
just one (the last one killed).
PREVIOUS TO MYSQL 8.0
Description :
-------------
The mysqld--defaults-file test fails when the test suite is run from a
non-canonical path, which happens when the current working directory
when mysql-test-run.pl is started contains a symbolic link.
The problem is that this test case uses --replace-result with
$MYSQL_TEST_DIR. This variable is a potentially non-canonical path
based on the current working directory when mtr is started. However,
the path in the expected error message from mysqld contains a
canonical path. This means it does not contain $MYSQL_TEST_DIR if
mtr's working directory is not the canonical path of the working
directory.
Because other tests produce output that may contain non-canonical
paths, making $MYSQL_TEST_DIR always canonical is not a fix.
Fix :
-----
Introduced a new environment variable '$ABS_MYSQL_TEST_DIR' which will
contin the canonical path to the test directory and replaced
$MYSQL_TEST_DIR with the new variable in main.mysqld--defaults-file
test file.
This is a back-port of BUG#24579973.

Since 736afe8680 the
mysql_system_tables_data.sql only installs the anonymous
user if skip_auth_anonymous IS NULL.
Its installation is prevented by setting this to 1.
It has its limitations, e.g. it assumes that there's only one
gdb and only one valgrind process is running. And a hard-coded
one-second delay might be too short for slow machines.
Still, it's better than "doesn't work at all"
MTR_COMBINATIONS contains comma-separated list of currently applied
combinations "x,y,...". MTR_COMBINATION_X, MTR_COMBINATION_Y, ... are
set to 1 for this list of combinations.
Fixed dead check: non-existent element $tinfo->{combination}.
Better use this clause:
use warnings FATAL => 'uninitialized';
But this must be very well tested.
- mysql_install_db now prints position to error file, if log-error is used
- Warning about compatibility now mentions MySQL 5.6 and 5.7
- Give warning if --show_compatibility_56 is used
for multi-file innodb_data_file_path.
Use fil_extend_space_to_desired_size() to correctly extend system
tablespace. Make sure to get tablespace size from the first tablespace
part.
The $result variable was supposed to accumulate failures from
all mysqltest processes (that analyzed all error logs in parallel).
But it was mistakenly put in the loop, so it was reset for each process.
