This patch contains the port of the MDEV-18379 patch
for 10.1 branch, but also includes a number of changes
made within MDEV-17835, which are necessary for the
normal operation of tests that use IPv6:
1) Fixed flaws in the galera_3nodes mtr suite control scripts,
because of which they could not work with mariabackup.
2) Fixed numerous bugs in the SST scripts and in the mtr test
files (galera_3nodes mtr suite) that prevented the use of Galera
with IPv6 addresses.
3) Fixed flaws in tests for rsync and mysqldump (for galera_3nodes
mtr tests suite). These tests were not performed successfully
without these fixes.
4) Currently, the three-node mtr suite for Galera (galera_3nodes)
uses a separate IPv6 availability check using the "have_ipv6.inc"
file. This check duplicates a more accurate check at suite.pm
level, which can be used by including the file "check_ipv6.inc".
This patch removes this discrepancy between suites.
5) GAL-501 test in the galera_3nodes suite does not contain the
option "--bind-address=::" which is needed for the test to work
correctly with IPv6 (at least on some systems), since without
it the server will not wait for connections on the IPv6 interface.

and partially https://jira.mariadb.org/browse/MDEV-17835
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.
Current versions of xtrabackup-v2 and mariabackup support the option
--innodb-data-home-dir, but this parameter is not passed to them from
the SST script, since the SST script does not receive this information
from mysqld. The transfer of this information to the SST is already
fixed by the MDEV-10754 patch, but we need to process it in the SST
script. Also, we should take into account that on the joiner side
the corresponding information is not read yet from the configuration
file (at the mysqld side) during the start of SST, so the script must
itself read it.

note that ${A#foo} is $A if there's no prefix foo. That's why
galera nodes tried to connect to 127.0.0.1:127.0.0.1 if there was
no port in the address
Followup for 2b35db5ac4
(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.
Backport/merge by Daniel Black <daniel@linux.vnet.ibm.com>
wrep_sst_common: Setting "-c ''" for my_print_defaults just takes no values from config at all. $MY_PRINT_DEFAULTS is already set at the top of the script to have --defaults-file and --defaults-extra-file. If WSREP_SST_OPT_CONF if set to "--defaults-file=/etc/my.cnf --defaults-extra-file=/etc/my.extra.cnf", then "my_print_defaults -c "" --defaults-file=/etc/my.cnf" succeeds, but if WSREP_SST_OPT_CONF is empty - no default values are taken at all.
wsrep_sst_xtrabackup-v2: innobackupex does not support --defaults-extra-file, so ${WSREP_SST_OPT_CONF} cannot be used as an argument, it has been changed to ${WSREP_SST_OPT_DEFAULT}. Removed --defaults-file= from INNOMOVE line, because WSREP_SST_OPT_CONF already includes it (INNOBACKUP was fine, INNOMOVE - not).
another followup for 4c2c057d40.
there are six possible cases:
--port can be set or not.
--address can be set, not set, or set but without a port number
The correct behavior is:
1 both --port and --address have a port number
- use it if it's the same, otherwise an error
2 only --port has the number (--address isn't set)
- use the value from --port
3 only --port has the number (--address is set, but has no port)
- use the value from --port
4 --port is unset, --address has the port number
- use the value from --address
5 --port is unset, --address has no port number
- use the value from --address, that is, port is empty string
6 --port is unset, --address is unset
- port is unset (an error somewhere later)
case 5 wasn't handled correctly
Fix for the following error messages during SST:
/usr/local/mysql/bin/wsrep_sst_rsync: 258: /usr/local/mysql/bin/wsrep_sst_rsync: [[: not found
/usr/local/mysql/bin/wsrep_sst_rsync: 263: /usr/local/mysql/bin/wsrep_sst_rsync: [[: not found
/usr/local/mysql/bin/wsrep_sst_rsync: 268: /usr/local/mysql/bin/wsrep_sst_rsync: [[: not found
wsrep_sst_xtrabackup-v2: innobackupex does not support --defaults-extra-file, so ${WSREP_SST_OPT_CONF} cannot be used as an argument, it has been changed to ${WSREP_SST_OPT_DEFAULT}. Removed --defaults-file= from INNOMOVE line, because WSREP_SST_OPT_CONF already includes it (INNOBACKUP was fine, INNOMOVE - not).
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.
Also, include fixes by Vladislav Vaintroub to the
aws_key_management plugin. The AWS C++ SDK specifically depends on
OPENSSL_LIBRARIES, not generic SSL_LIBRARIES (such as YaSSL).
Revoked executable bit from files that are not supposed to be executed directly.
Removed interpreted from files that are not supposed to be executed directly.
Added interpreter to files that are supposed to be executed directly.
