MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to

values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are

7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

MDEV-18863: Galera SST scripts can't read [mysqldN] option groups
Some users and some scripts (for example, mysqld_multi.sh) use special
option groups with names like [mysqld1], [mysqld2], ..., [mysqldN].
But SST scripts can't currently fully support these option groups.
The only option group-related value it gets from the server is
--defaults-group-suffix, if that option was set for mysqld when
the server was started.
However, the SST scripts does not get told by the server to read
these option groups, so this means that the SST script will fail
to read options like innodb-data-home-dir when it is in a option
group like [mysqld1]...[mysqldN].
Moreover, SST scripts ignore many parameters that can be passed
to them explicitly and cannot transfer them further, for example,
to the input of mariabackup utility. Ideally, we want to transfer
all the parameters of the original mysqld call to utilities such
as mariabackup, however the SST script does not receive these
parameters from the server and therefore cannot transfer them to
mariabackup.
To correct these shortcomings, we need to transfer to the scripts
all of the parameters of the original mysqld call, and in the SST
scripts themselves provide for the transfer all of these parameters
to utilities such as mariabackup. To prevent these parameters from
mixing with the script's own parameters, they should be transferred
to SST script after the special option "--mysqld-args", followed by
the string argument with the original parameters, as it received by
the mysqld call at the time of launch (further all these parameters
will be passed to mariabackup, for example).
In addition, the SST scripts themselves must be refined so that
they can read the parameters from the user-selected group, not just
from the global mysqld configuration group. And also so that they
can receive the parameters (which important for their work) as
command-line arguments.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port

fail;

then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all

5) Waiting for the start of the transport channel (socat, nc, rsync,

the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in

it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output

after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script

2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but

is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],

to use and to test the encypt=1 encryption without installing

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted

list of arguments after --mysqld-args are perceived as two different

match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part

It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted

list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and
is synchronized across patterns that used to check the output
of these utilities;
7) In SST via mariabackup, the signal about readiness to receive data
is sometimes sent too early - immediately after listen(), and not
after accept() (which are called by socat or netcat utility).
8) Checking availability of the some options of some utilities was
done using the grep pattern, which easily gives false positives;
9) Common name (CN) for local addresses, if not explicitly specified,
is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.

MDEV-24962: Galera SST innobackupex-move ignores Environment settings
After switching to the new mariabackup interface (instead of
the outdated innobackupex interface, which is supported for
compatibility), we need to explicitly pass a path to the datadir
directory as a parameter, since in the new interface the value
of this option is not automatically set in such a way that it
always matches the SST/IST logic. This commit adds passing this
option as an explicit parameter to mariabackup. This commit also
removed unnecessary options that are not used and not supported
by mariabackup.
Also, numerous flaws in the common wsrep_sst_common script have
been fixed:
1) There are many bash-specific constructs in the script that
may not be supported by other interpreters, which can lead
to the most unexpected errors during SST, because failures
in the interpretation of bash-specific constructs lead to
incorrect parsing of arguments;
2) There is parse_cnf() function which is often called by other
scripts for the "mysqld" or "--mysqld" group, but it does not
take into account the default group suffix, which leads to
reading values only from the default group, which then leads
to errors due to reading the default values instead of the
values for a specific group;
3) Some options such as --user, --innodb-data-home-dir or --datadir
are not removed from the --mysqld-args list, although they are
processed inside scripts (and passing of these options funther
may cause problems for mariabackup);
4) If an argument that the script understands is present in
the --mysqld-args list twice, then this causes SST to fail,
instead of reading the most recent value;
5) The "--host" parameter is technically still supported among
the arguments of the SST scripts, but in reality scripts do not
work with it as expected, especially if it has an IPv6 address;
6) If the port number is absent in the --address parameter value,
but the port number is explicitly passed through the --port
argument, then the scripts for mariabackup and xtrabackup-v2
fail;
7) If a new address interface is used (with the --address parameter),
then automatic default port substitution is not performed, although
it is supported for the legacy --host/--port interface.
8) If there are spaces in the parameter values after --mysqld_args,
then their further transfer does not occur correctly, which
causes mariabackup to fail during SST - the space splits
the argument in such a way that it breaks the parsing of the
following parameters;
9) If most of the parameters that are names or paths to the files
or directories contain spaces, then SST scripts fail in an
unpredictable way due to incorrect variable substitutions;
10) If the --log-bin option is passed among the arguments of myqlds
(--mysqld-args) without a parameter, and the --binlog option
is not specified, then the script cannot substitute the default
name for binlog and cannot construct binlog name using the
--log-basename argument (which is against server specifications);
11) Tail slashes are not removed from the directory names, which,
upon further substitution, leads to the appearance of a double
slash in the file paths;
12) The explicit --binlog parameter (which is now always transmitted
from the server side) and the "hidden" --log-bin parameter in the
list of arguments after --mysqld-args are perceived as two different
parameters in different parts of the scripts, and if they are do not
match for some reason, this will lead to failures during SST;
Also, all new changes from the 10.6 branch have been migrated here,
including the latest pull requests for authentication (only the part
that concerns SST scripts).
It also fixes dozens of other bugs in all SST scripts.

MDEV-23580: WSREP_SST: [ERROR] rsync daemon port has been taken
This commit contains a large set of further bug fixes and
improvements to SST scripts for Galera, continuing the work
that was started in MDEV-24962 to make SST scripts work smoothly
in different network configurations (especially using ipv6) and
with different environment settings:
1) The ipv6 addresses were incorrectly handled in the SST script
for rsync (incorrect address substitution for establishing a
connection, incorrect address substitution for bind, and so on);
2) Checking the locality of the ip-address in SST scripts did not
support ipv6 addresses (such as "[::1]"), which were falsely
identified as non-local ip, which further did not allow running
two SSTs on different local addresses on the same machine.
On the other hand, this bug masked some other errors (related
to handling ipv6 addresses);
3) The code for checking the locality of the ip address was different
in the SST scripts for rsync and for mysqldump, with individual
flaws. This code is now made common and moved to wsrep_sst_common;
4) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
did not process ipv6 addresses correctly in all cases (not for all
branches);
5) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) in the wait_for_listen() and check_pid_and_port() functions
for some code branches could give a false positive result due to
the textual match of prefixes in the port number and/or PID of
the process;
6) Waiting for the start of the transport channel (socat, nc, rsync,
stunnel) was supported through different utilities in SST scripts
for mariabackup and for rsync, and with various minor flaws in
the code. Now the code is still different in these scripts, but
it supports a common set of utilities (lsof, ss, sockstat) and

is sometimes sent too early - immediately after listen(), and not

is now always replaced to "localhost" to avoid the need to generate
many separate certificates for local addresses of one machine and
not to depend on which the local address is currently used in test
(ipv4 or ipv6, etc.);
10) In tests galera_sst_mariabackup_encrypt_with_key_server and
galera_sst_rsync_encrypt_with_key_server the correct certificate
is selected to avoid commonname (CN) mismatch problems;
11) Further refactoring to protect against spaces in file names.
12) Further general refactoring to eliminate bash-specific constructs
or to improve code readability;
13) The code for setting options for the nc (netcat) utility was
different in different scripts for SST - now it is made identical.
14) Fixed long-time broken encryption via xbcrypt in combination with
mariabackup and added support for key-based encryption via openssl
utility, which is now enabled by default for encrypt=1 mode (this
default mode can be changed using a new configuration file option
"encypt-format=openssl|xbcrypt", which can be placed in the [mysqld],
[sst] or in the [xtrabackup] section) - this change will allow us
to use and to test the encypt=1 encryption without installing
non-standard third-party utilities.
