buf_page_get_gen(): Relax the assertion once more.
The LSN may grow by invoking ibuf_upgrade(), that is,
when upgrading files where innodb_change_buffering!=none was used.
The LSN may also have been recovered from a log that needs
to be upgraded to the current format.
With wsrep_sst_rsync, node goes into endless loop when trying
to establish connection to donor for IST/SST if the database
is bind on specific IP address, not the "*".
This commit fixes this problem. Separate tests are not
required - the problem can occur in normal configurations
on a number of systems when selecting a bing address other
than "*", especially on FreeBSD and with the IPv6 addresses.
int wsrep_thd_append_key(THD*, const wsrep_key*, int, Wsrep_service_key_type)
CREATE TABLE [SELECT|REPLACE SELECT] is CTAS and idea was that
we force ROW format. However, it was not correctly enforced
and keys were appended before wsrep transaction was started.
At THD::decide_logging_format we should force used stmt binlog
format to ROW in CTAS case and produce a warning if used
binlog format was not ROW.
At ha_innodb::update_row we should not append keys similarly
as in ha_innodb::write_row if sql_command is SQLCOM_CREATE_TABLE.
Improved error logging on ::write_row, ::update_row and ::delete_row
if wsrep key append fails.

It currently serves no real purpose, but is suspected to cause occasional
error when foreign keys are used.

A mixture of a multi-byte *TEXT column and a short binary column
produced a too large column.
For example, COALESCE(tinytext_utf8mb4, short_varbinary)
produced a BLOB column instead of an expected TINYBLOB.
- Adding a virtual method Type_all_attributes::character_octet_length(),
returning max_length by default.
- Overriding Item_field::character_octet_length() to extract
the octet length from the underlying Field.
- Overriding Item_ref::character_octet_length() to extract
the octet length from the references Item (e.g. as VIEW fields).
- Fixing Type_numeric_attributes::find_max_octet_length() to
take the octet length using the new method character_octet_length()
instead of accessing max_length directly.
1. it links with ${SSL_LIBRARIES}, in WolfSSL builds it's a static
library, so when a plugin is loaded there will be two copies of
wolfssl in the same address space. It breaks odr (at least).
2. Plugin can linked with OpenSSL and the server with WolfSSL or
vice versa. It might load, but then we'll have both WolfSSL and
OpenSSL at the same time. Kind of risky.
Fix: link the plugin statically into the server if it's a WolfSSL build

PARSEC: Password Authentication using Response Signed with Elliptic Curve
new authentication plugin that uses salted passwords,
key derivation, extensible password storage format,
and both server- and client-side scrambles.
It signs the response with ed25519, but it uses stock
unmodified ed25519 as provided by OpenSSL/WolfSSL/GnuTLS.

fprintf() on Windows, when used on unbuffered FILE*, writes bytewise.
This can make crash handler messages harder to read, if they are mixed up
with other error log output.
Fixed , on Windows, by using a small buffer for formatting, and fwrite
instead of fprintf, if buffer is large enough for message.
The reason is that on Windows, OpenSSL can be built with different C runtime
than the server (e.g Debug runtime in debug vcpkg build).
Overwriting only malloc(), with CRT that server is using can cause
mixup of incompatible malloc() and free() inside openssl.
To fix, overwrite all memory functions.
Assertion `table->field[0]->ptr >= table->record[0] &&
table->field[0]->ptr <= table->record[0] + table->s->reclength' failed in
handler::assert_icp_limitations.
table->move_fields has some limitations:
1. It cannot be used in cascade
2. It should always have a restoring pair.
Rule 1 is covered by assertions in handler::assert_icp_limitations
and handler::ptr_in_record (commit 30894fe9a9).
Rule 2 should be manually maintained with care. Hopefully, the rule 1 assertions
may sometimes help as well.
In ha_myisam::repair, both rules are broken. table->move_fields is used
asymmetrically there: it is set on every param->fix_record call
(i.e. in compute_vcols) but is restored only once, in the end of repair.
The reason to updating field ptr's for every call is that compute_vcols can
(supposedly) be called in parallel, that is, with the same table, but different
records.
The condition to "unmove" the pointers in ha_myisam::restore_vcos_after_repair
is incorrect, when stored vcols are available, and myisam stores a VIRTUAL field
if it's the only field in the table (the record cannot be of zero length).
This patch solves the problem by "unmoving" the pointers symmetrically, in
compute_vcols. That is, both rules will be preserved maintained.
Before this change the unix socket auth plugin returned true only when
the OS socket user id matches the MariaDB user name.
The authentication string was ignored.
Now if an authentication string is defined with in `unix_socket`
authentication rule, then the authentication string will be used to
compare with the socket's user name, and the plugin will return a
positive if matching.
Make the plugin to fill in the @@external_user variable.
This change is similar to MySQL commit of
https://github.com/mysql/mysql-server/commit/6ddbc58e.
However there's one difference with above commit:
- For MySQL, both Unix user matches DB user name and Unix user matches the
authentication string will be allowed to connect.
- For MariaDB, we only allows the Unix user matches the authentication
string to connect, if the authentication string is defined.
This is because allowing both Unix user names has risks and couldn't
handle the case that a customer only wants to allow one single Unix user
to connect which doesn't matches the DB user name.
If DB user is created with multiple unix_socket options for example:
`create user A identified via unix_socket as 'B' or unix_socket as 'C';`
Then both Unix user of B and C are accepted.
Existing MTR test of `plugins.unix_socket` is not impacted.
Also add a new MTR test to verify authentication with authentication
string. See the MTR test cases for supported/unsupported cases.

in bintars the server is linked with wolfssl, while the connector
is linked with gnutls. Thus client_ed25519.so gets gnutls
dependency, unresolved symbols and it cannot be loaded into the
server and gnutls symbols aren't present there.
linking the plugin statically with gnutls fixes that and the test passes.
but when such a plugin is loaded into the client, the client gets
two copies of gnutls - they conflict and ssl doesn't work at all.
let's detect this and disable the test for now.
Modified node config with longer timeouts for suspect,
inactive, install and wait_prim timeout. Increased
node_1 weight to keep it primary component when
other nodes are voted out.
