Start general log OFF and then truncate mysql.general_log and
use proper wait timeouts to make sure it is really empty.

If --innodb-undo-tablespaces is used, then InnoDB stores undo in a
separate file(s) which whould also be replicated.
This fixes

This way it is more readable and easy to change, also if a new entry is
added or one removed, the diff will be easier to read.

Check that cluster weight have proper values in galera_pc_weight
test. Removed sleeps from tests and added condition waits for
expected cluster sizes. Replaced galera suspend/resume with
gmcast.isolate in order to avoid breaking client connections
to server which is isolated from the cluster and to avoid
the need to reset wsrep_cluster_address.
Re-recorded galera_defaults.

Adding a FK constraint to an existing table (ALTER TABLE ADD FOREIGN
KEY) causes the applier to fail, if a concurrent DML statement that
violate the new constraint (i.e. a DELETE or UPDATE of record in the
parent table).
For exmaple, the following scenario causes a crash in the applier:
1. ALTER successfully adds FK constraint in node_1
2. On node_2 is UPDATE is in pre_commit() and has certified successfully
3. ALTER is delivered in node_2 and BF aborts DML
4. Applying UPDATE event causes FK violation in node_1
To avoid this situation it is necessary for UPDATE to fail during
certification. And for the UPDATE to fail certfication it is necessary
that ALTER appends certification keys for both the child and the parent
table. Before this patch, ALTER TABLE ADD FK only appended keys for
child table which is ALTERed.

don't create static objects that destroy mutexes from destructors,
and don't destroy mutexes from .so destructor (on-unload) function.
if it happens after exit(), P_S will be long gone by that time

ha_innobase::delete_table and log semaphore wait upon concurrent DDL with foreign keys
Disable "Invalid (old?) table or database name" warning when
converting table names in InnoDB's get_foreign_key_info().
Because a name can be a temporary table name during the ALTER TABLE,
and some other thread can do SHOW CREATE TABLE for the other table
in the FK relationships _anytime_.

ha_innobase::delete_table and log semaphore wait upon concurrent DDL with foreign keys
ALTER TABLE locks the table with TL_READ_NO_INSERT, to prevent the
source table modifications while it's being copied. But there's an
indirect way of modifying a table, via cascade FK actions.
After previous commits, an attempt to modify an FK parent table
will cause FK children to be prelocked, so the table-being-altered
cannot be modified by a cascade FK action, because ALTER holds a
lock and prelocking will wait.
But if a new FK is being added by this very ALTER, then the target
table is not locked yet (it's a temporary table). So, we have to
lock FK parents explicitly.

table_already_fk_prelocked() was looking for a table in the wrong
list (not the complete list of prelocked tables, but only in its tail,
starting from the current table - which is always empty for the last
added table), so for circular FKs it kept adding same tables to the list
indefinitely.

execution of SP
The problem was that join_columns creation was not finished due to error of notfound column in USING, but next execution tried to use join_columns lists.
Solution is cleanup the lists on error. It can eat memory in statement MEM_ROOT but it is an error and error will be fixed or statement/procedure removed/altered.

Problem was that SQL level tried to read a record with rnd_pos()
that was already deleted by the same statement.
In the case where the page for the record had been deleted, this
caused an assert.
Fixed by extending the assert to also handle empty pages and
return HA_ERR_RECORD_DELETED for reads to deleted pages.
