* Increased timeout counter in galera_wait_ready.inc
* Replaced useless include/wait_until_ready.inc after start_mysqld.inc
in galera_st_*.inc with wait_condition on cluster size.
Test galera_sst_mysqldump often fails with error "2013: Lost connection
to MySQL server during query". The connection is lost after the test
restart one of the nodes. This happens because the server closes client
connections if it is joining a cluster through SST method mysqldump.
On unlucky runs of the test it is possible that mysqld is restarted,
and then mtr client is disconnected while it tries to determine if
galera is ready before going on with the test.
This patch rewrites galera_wait_ready.inc so that it is immune to
being disconnected.
This patch fixes a lock wait timeout error on `SELECT @@GLOBAL.WSREP_ON`
in `wait_wsrep_ready.inc`:
```
--connection node_2
...
--source include/kill_galera.inc
--connection node_1
--source include/wait_until_connected_again.inc # This includes wait_wsrep_ready.inc
```
The problem is that on node_2, kill_galera.inc may return before
the node is killed. So node_1 may still see that node_1 is alive
and will attempt to sync wait when doing those `SELECT` statements.
But sync wait is doomed to fail given that node_1 is killed, hence
the lock wait timeout.
One possible fix is to disable wsrep_sync_wait before including
wait_until_connected_again.
However, it appears that including wait_until_connected_again is
not necessary at all in node_1, so this patch removes it altogether.
kill_galera.inc can no longer rely on wait_until_connected_again.inc.
This is because wait_until_connected_again now tries to make sure
that the server it is connected eventually transition to ready
state. Whereas some tests may need to kill galera while the server
is in a non-primary view.
galera SST tests have a debug part, but we don't want to limit them
to fulltest2 builder. So, add support for test files that
have a debug part:
* add maybe_debug.inc and maybe_debug.combinations
* 'debug' combination is run when debug is available
* 'release' combination is run otherwise
* test wraps debug parts in if($with_debug) { ... }
* and creates ,debug.rdiff for debug results
* make galera.galera_sst_xtrabackup* not big
* auto-select between socat and nc, whatever available
* auto-skip xtrabackup tests if no xtrabackup or neither socat nor nc
fix galera.galera_sst_mysqldump test to work:
* must connect to 127.0.0.1, where mysqld is listening
* disable wsrep_sync_wait in wsrep_sst_mysqldump, otherwise
sst can deadlock
* allow 127.0.0.1 for bind_address and wsrep_sst_receive_address.
(it's useful in tests, or when two nodes are on the same box,
or when nodes are on different boxes, but the connection is
tunelled, or whatever. Don't judge user's setup). MDEV-14070
* don't wait for client connections to die when doing
mysqldump sst. they'll die in a due time, and if needed mysql
will wait on locks until they do. MDEV-14069
Also don't mark it big, to make sure it's sufficiently tested
The error log redirection for wsrep_recover run does not work in old version.
For the wsrep_recovery run, error logging is supposed to go into:
mysql-test/suite/galera/include/galera_wsrep_recover.inc
In old version, this works only partially, 4 first lines of error messages after mysql startup
do go into the galera_wsrep_recover.log, but after that the default error log file is enforced
and remaining error logging goes into the default error log file.
In this patch this problem is fixed by passing --log-error option in mysql startup
This fix was tested with galera_gcache_recover test, which is currently in disabled state.
Note that the test does not pass even after this fix, as there are further more issues
in later test phases.
dict_create_or_check_foreign_constraint_tables(): Change the warning
about the foreign key metadata table creation to a note.
Remove messages after metadata table creation. If the creation fails,
startup will abort with a message. Normally the creation succeeds on
bootstrap, and the messages would only be noise.
Remove the related suppressions from the tests.
