The code became unused in commit 10590dd3.

Add check that file key management plugin is found.

fil_space_t::add(): Replaces fil_node_create(), fil_node_create_low().
Let the caller pass fil_node_t::handle, to avoid having to close and
re-open files.

fil_node_t::read_page0(): Refactored from fil_node_open_file().
Read the first page of a data file.

fil_node_open_file(): Open the file only once.

srv_undo_tablespace_open(): Set the file handle for the opened
undo tablespace. This should ensure that ut_ad(file->is_open())
no longer fails in recv_add_trim().

xtrabackup_backup_func(): Remove some dead code.

xb_fil_cur_open(): Open files only if needed. Undo tablespaces
should already have been opened.

trx_assign_rseg_low(): Skip dedicated undo tablespaces if
innodb_undo_tablespaces=0 has been set after the database was created.

When dropping a partially created table due to failure,
use SQLCOM_TRUNCATE instead of SQLCOM_DROP_DB, so that
no foreign key constraints will be touched. If any
constraints were added as part of the creation, they would
be reverted as part of the transaction rollback.

We need an explicit call to row_drop_table_for_mysql(),
because InnoDB does not do proper undo logging for CREATE TABLE,
but would only drop the table at the end of the rollback.
This would not work if the transaction combines both
RENAME and CREATE, like TRUNCATE now does.

If a table had a KEY_BLOCK_SIZE attribute, but no ROW_FORMAT,
it would be created as ROW_FORMAT=COMPRESSED in InnoDB.
However, TRUNCATE TABLE would lose the KEY_BLOCK_SIZE attribute
and create the table with the innodb_default_row_format (DYNAMIC).

This is a regression that was introduced by MDEV-13564.

update_create_info_from_table(): Copy also KEY_BLOCK_SIZE.

The test galera_sst_mariabackup_table_options was disabled,
because the server refuses to start up due to wrong parameters.

The error handling in the MDEV-13564 TRUNCATE TABLE was broken
when an error occurred during table creation.

row_create_index_for_mysql(): Do not drop the table on error.

fts_create_one_common_table(), fts_create_one_index_table():
Do drop the table on error.

create_index(), create_table_info_t::create_table():
Let the caller handle the index creation errors.

ha_innobase::create(): If create_table_info_t::create_table()
fails, drop the incomplete table, roll back the transaction,
and finally return an error to the caller.

lock_rec_queue_validate(): Assert page_rec_is_leaf(rec), except when
the record is a page infimum or supremum.

lock_rec_validate_page(): Relax the assertion that failed.
The assertion was reachable when the record lock bitmap was empty.

lock_rec_insert_check_and_lock(): Assert page_is_leaf().

Replace table->space->id with table->space_id.

MDEV-17804: Galera tests cause mysql_socket.h:738: inline_mysql_socket_send: Assertion `mysql_socket.fd != -1' failed.

Do not do end of statement logic if thd is already killed as
socket is already closed.

Problem was that controlling connection i.e. connection that
executed the query SET GLOBAL wsrep_reject_queries = ALL_KILL;
was also killed but server would try to send result from that
query to controlling connection resulting a assertion
mysqld: /home/jan/mysql/10.2-sst/include/mysql/psi/mysql_socket.h:738: inline_mysql_socket_send: Assertion `mysql_socket.fd != -1' failed.
as socket was closed when controlling connection was closed.

wsrep_close_client_connections()
	Do not close controlling connection and instead of
	wsrep_close_thread() we do now soft kill by THD::awake

wsrep_reject_queries_update()
	Call wsrep_close_client_connections using current thd.

Disable galera_3nodes tests using xtrabackup.

Disable galera tests using xtrabackup.

Record result files for 10.2.

Add test case for encrypted and page compressed tables.

recv_addr_trim(): Do not try to detach the hash bucket, because
the code for doing that does not always work.

recv_apply_hashed_log_recs(): Do not attempt to read pages for which
there exist no redo log records.

for debug build.

Skip tests which expectedly fail when Aria is not used for temporary tables

Remove unnecessary have_debug requirement, record results using
release build and create .rdiff file for debug builds where
needed.

Commit ff88e4bb broke the Windows build.
Clean up one more redundant #include to fix it.
