MDEV-29533 Crash when MariaDB is replica of MySQL 8.0 MySQL 8.0 has added the following new events in the MySQL binary log PARTIAL_UPDATE_ROWS_EVENT TRANSACTION_PAYLOAD_EVENT HEARTBEAT_LOG_EVENT_V2 - PARTIAL_UPDATE_ROWS_EVENT is used by MySQL to generate update statements using JSON_SET, JSON_REPLACE and JSON_REMOVE to make update of JSON columns more efficient. These events can be disabled by setting 'binlog-row-value-options=""' - TRANSACTION_PAYLOAD_EVENT is used by MySQL to signal that a row event is compressed. It an be disably by setting 'binlog_transaction_compression=0'. - HEARTBEAT_LOG_EVENT_V2 is written to the binary log many times per seconds. It can be ignored by the server. What this patch does: - If PARTIAL_UPDATE_ROWS_EVENT or TRANSACTION_PAYLOAD_EVENT is found, the server will stop with an error message of how to disable the MySQL server to generate such events. - HEARTBEAT_LOG_EVENT_V2 events are ignored. - mariadb-binlog will write the name of the new events. - mariadb-binlog will stop if PARTIAL_UPDATE_ROWS_EVENT or TRANSACTION_PAYLOAD_EVENT is found, unless --force is given. - Fixes a crash in mariadb-binlog if a character set unknown to MariaDB is found. (MDEV-29533) From Kristian Nielsen: - Add test case for MySQL 8.0 to MariaDB replication and fixed a a small typo in post_header_len initialization. Reviewer: knielsen@mariadb.org
