- Fixes a situation in which a thread gets BF aborted and does not send the reply back to
the client, even though the connection is still alive. That caused
both sides to hang waiting for the next message. Now we explicitly
check that the connection is still alive.
- MTR test for the above
- Replaced thd->killed assignments to thd->reset_kill_query where applicable.

Backport Bug#45852 Semisynch: Last_IO_Error: Fatal error: Failed
to run 'after_queue_event' hook
Errors when send reply to master should never cause the IO thread
to stop, because master can fall back to async replication if it
does not get reply from slave.
The problem is fixed by deliberately ignoring the return value of
slave_reply.
Command COM_SHUTDOWN was rejected in non-Primary because
server_command_flags[COM_SHUTDOWN] had value CF_NO_COM_MULTI
instead of CF_SKIP_WSREP_CHECK.
As a fix removed assignment
server_command_flags[CF_NO_COM_MULTI]= CF_NO_COM_MULTI
which overwrote server_command_flags[COM_SHUTDOWN].
The test had been disabled in 10.2 due to frequent failures,
in 5ec9b88e11.
After the problems were addressed, we failed to re-enable the test
until now.
Conversion to a temporal data type resulting into a lower precision
depends on TIME_ROUND_FRACTIONAL. Taking into account this dependency in:
- indexed generated virtual column expressions
- persistent virtual column expressions
A warning is now issued if conversion from the generation expression
to the column data type depends on TIME_ROUND_FRACTIONAL.
The warning will be changed to error in 10.5
Command COM_SHUTDOWN was rejected in non-Primary because
server_command_flags[COM_SHUTDOWN] had value CF_NO_COM_MULTI
instead of CF_SKIP_WSREP_CHECK.

which overwrote server_command_flags[COM_SHUTDOWN].
This reverts commit 5a9e2b77d4 in 10.5,
so it produces an error on "bad" generated columns.
Note, 10.2, 10.3, 10.4 produce only warnings, for backward compatibility.

WL#4618 RBR: extended table metadata in the binary log
This patch extends Table Map Event. It appends some new fields for
more metadata. The new metadata includes:
- Signedness of Numberic Columns
- Character Set of Character Columns and Binary Columns
- Column Name
- String Value of SET Columns
- String Value of ENUM Columns
- Primary Key
- Character Set of SET Columns and ENUM Columns
- Geometry Type
Some of them are optional, the patch introduces a GLOBAL system
variable to control it. It is binlog_row_metadata.
- Scope: GLOBAL
- Dynamic: Yes
- Type: ENUM
- Values: {NO_LOG, MINIMAL, FULL}
- Default: NO_LOG
Only Signedness, character set and geometry type are logged if it is MINIMAL.
Otherwise all of them are logged.
Also add a binlog_type_info() to field, So that we can have extract
relevant binlog info from field.
Files for PAGE_COMPRESSED tables that were created with
innodb_checksum_algorithm=full_crc32 store the value of
innodb_compression_algorithm at the time of the file creation.
The server-wide setting of innodb_compression_algorithm
may be changed after file creation. We must ignore any mismatch
when opening a data file, and for writes, we must use the
choice of algorithm that is stored in the file.
fil_space_t::is_flags_full_crc32_equal(): Ignore the
innodb_compression_algorithm but do compare innodb_page_size.
fil_space_t::is_flags_non_full_crc32_equal(): Ignore the
innodb_compression_algorithm.
The test mariabackup.encrypted_page_corruption was hard-wired
for innodb_checksum_algorithm=crc32. Enable a combination for
full_crc32 for the sake of completeness.
Re-enable some Galera tests that should have been enabled.
Add client_ed25519.so to debian/libmariadb3.install;
merge e47a143fc0 correctly.
Remove a duplicated #include from wsrep_mysqld.cc.
* do not allow versioned table to be without versioned (non-system) fields
* prohibit changing field versioning, when removing table versioning
* handle CREATE...SELECT as well
The setting innodb_change_buffering_debug=2 was supposed to inject
a crash during change buffer merge. There is no public test for
that functionality, and even if there were, it would be better
to use DEBUG_SYNC to halt the thread that does change buffer merge,
force a redo log flush from another thread, and finally kill the
server externally.
InnoDB intentionally (it's a documented behavior) ignores changing of
DATA DIRECTORY and INDEX DIRECTORY for partitions. Though we should
issue warning when this happens.
After SST from master node (the one where event is ENABLED) - you will end up with the event enabled on two nodes, hence it's now being executed twice. It can be solved by comparing event's originator with server_id. if not equal, then change its status to 'SLAVESIDE_DISABLED'

Try to use more deterministic floating-point operations.
Apparently, 2.2 > 2.2 wrongly holds on many platforms, but
not ppc64le on the compiler used on Red Had Enterprise Linux 8.
The reason could be an infinite binary presentation:
2.2 = 0b10.001100110011…
With t1_f = 2.5 = 0b10.1, t1_f > 2.5 would no longer hold on AMD64.
Let us replace the 2.2 with 2.5 and compare t1_f >= 2.5 in order to
get more consistent results across all platforms.
