Corrects the following error with rsync sst on FreeBSD:
WSREP_SST: [ERROR] rsync daemon port '4444' has been taken
The FreeBSD version of grep doesn't play nicely with the -w parameter mixed with [[:space:]] and ends up matching nothing. This causes the script to loop and attempt to spawn more than one instance of rsync, which fails with the initial instance already having the port open. Because of this, the entire script fails and no sst occurs resulting in the error message listed above appearing in the log file.
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)
In summary, wsrep_node_address and wsrep_sst_receive_address can now
be set to IPv6 addresses escaped by []. Rsync SST works out ouf the
box thanks to rsync daemon listening on both IPv4 and IPv6 sockets by
default. For xtrabackup SST onver IPv6 one needs to set sockopt in
the [sst] section of joiner's configuration file to ",pf=ip6" if
using socat as a streamer or to "-6" if using netcat.

In rsync based SST method, during third phase of data transfer,
'lost+found' should be filtered out while recursively transferring
files from various directories under data directory.
During SST, since wsrep_sst_rsync waits for mysqld to create
"tables_flushed" file after it has successfully executed FTWRL,
it would wait forever if FTWRL fails.
Fixed by introducing a mechanism to report failure to the script.
MTR drops the datadir in the event of a test failure. In case mysqld
is running as a Galera node and a failure occurs while the SST is in
progress, the rsync pid file gets removed as part of the cleanup and
wsrep_sst_rsync, which relies on this file, fails to kill the rsync.
Fixed by using the cached $RSYNC_REAL_PID to kill rsync daemon.
1. Passes wsrep_sst_auth_value to SST scripts via WSREP_SST_OPT_AUTH envronmental variable, so it never appears on the command line
2. In mysqldump and xtrabackup* SST scripts which rely on MySQL authentication, instead of passing password on the command line, SST script sets MYSQL_PWD environment variable, so that password also never appears on the mysqldump/innobackupex command line.
pass --defaults-file and --defaults-extra-file
(whatever was specified, or none)
from mysqld down to SST scripts.
parse these options in SST scripts and pass them down
to mysqldump, my_print_defaults, and xtrabackup
Merged lp:maria/maria-10.0-galera up to revision 3879.
Added a new functions to handler API to forcefully abort_transaction,
producing fake_trx_id, get_checkpoint and set_checkpoint for XA. These
were added for future possiblity to add more storage engines that
could use galera replication.
