Problem was that in SST log_bin_index name and directory was not
handled and passed to rsync SST script.
wsrep_sst_common.sh
Read binlog index dirname and filename if --binlog-index
parameter is provided. Read binlog filenames from that file
from donor and write transfered binlog filenames to that
file in joiner.
mysqld.cc, mysqld.h
Moved opt_binlog_index_name from static to global and added
it to extern.
wsrep_sst.cc
generate_binlog_index_opt_val
New function to generate binlog index name if opt_binlog_index_name is
given on configuration.
sst_prepare_other
Add binlog index configuration to SST command.
wsrep_sst.h
Add new SST parameter --binlog-index
Add test case.

This is a typical systemd response where it tries to shutdown the
joiner (due to "timeout") before the joiner manages to complete SST.
wsrep_sst_wait
wsrep_SE_init_wait
While waiting the operation to finish use mysql_cond_timedwait
instead of mysql_cond_wait and if operation is not finished
extend systemd timeout (if needed).
* xtrabackup no longer support --compact
* wsrep_sst_mysqldump wasn't always using --default-file
* wsrep_sst.cc overquoted --default-file for wsrep_sst_mysqldump
also remove redundant lines config and test lines, compiler warnings,
and mark big tests as big.
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
(from 10.1 to 10.0-galera)
This conflicted signficantly with 7d550c76be
which added --defaults-group-suffix support.
Took the approach of 4bb49d84a9 and adapted the
--defaults-group-suffix handling to be consistent.
The following changes as follows:
SST scripts now use $MY_PRINT_DEFAULTS rather than the lowercase for
consistency and this include all required --default arguements.

Problem was incorrect definition of wsrep_recovery,
trx_sys_update_wsrep_checkpoint and
trx_sys_read_wsrep_checkpoint functions causing
innodb_plugin not to load as there was undefined symbols.
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.
.. file '/var/log/mysql/mariadb-bin.000001' not found in binlog
index, needed for recovery. Aborting.
In Galera cluster, while preparing for rsync/xtrabackup based
SST, the donor node takes an FTWRL followed by (REFRESH_ENGINE_LOG
in rsync based state transfer and) REFRESH_BINARY_LOG. The latter
rotates the binary log and logs Binlog_checkpoint_log_event
corresponding to the penultimate binary log file into the new file.
The checkpoint event for the current file is later logged
synchronously by binlog_background_thread.
Now, since in rsync/xtrabackup based snapshot state transfer methods,
only the last binary log file is transferred to the joiner node; the
file could get transferred even before the checkpoint event for the
same file gets written to it. As a result, the joiner node would fail
to start complaining about the missing binlog file needed for recovery.
In order to fix this, a mechanism has been put in place to make
REFRESH_BINARY_LOG operation wait for Binlog_checkpoint_log_event
to be logged for the current binary log file if the node is part of
a Galera cluster. As further safety, during rsync based state transfer
the donor node now acquires and owns LOCK_log for the duration of file
transfer during SST.
- reverted from tracking donor servicing thread. With xtrabackup SST,
xtrabackup thread will call FTWRL and node is desynced upfront
- Skipping desync in FTWRL if node is operating as donor
- enveloped FTWRL processing with wsrep desync/resync calls. This way FTWRL processing node
will not cause flow control to kick in
- donor servicing thread is unfortunate exception, we must let him to pause provider as part
of FTWRL phase, but not desync/resync as this is done as part of donor control on higher
level
The memory alloc-ed initially for wsrep_sst_auth to store the
value specified in config was lost as the global variable was
reset while in process of masking it and thus, could never be
reclaimed on shutdown.

- Validate the specified wsrep_start_position value by also
checking the return status of wsrep->sst_received. This also
ensures that changes in wsrep_start_position is not allowed
when the node is not in JOINING state.
- Do not allow decrease in seqno within same UUID.
- The initial checkpoint in SEs should be [0...:-1].
- Change some static variables to dynamic to ensure that we don't do any memory
allocations before server starts or stops
- Print more memory information on SIGHUP. Fixed output.
- Write out if memory was lost if run with --debug-at-exit
- Fixed wrong #ifdef in sql_cache.cc
