This patch contains a fix for the MDEV-17262/17243 issues and new mtr test. These issues (MDEV-17262/17243) have two reasons: 1) After an intermediate commit, a transaction loses its status of "transaction that registered in the MySQL for 2pc coordinator" (in the InnoDB) due to the fact that since version 10.2 the write_row() function (which located in the ha_innodb.cc) does not call trx_register_for_2pc(m_prebuilt->trx) during the processing of split transactions. It is necessary to restore this call inside the write_row() when an intermediate commit was made (for a split transaction). Similarly, we need to set the flag of the started transaction (m_prebuilt->sql_stat_start) after intermediate commit. The table->file->extra(HA_EXTRA_FAKE_START_STMT) called from the wsrep_load_data_split() function (which located in sql_load.cc) will also do this, but it will be too late. As a result, the call to the wsrep_append_keys() function from the InnoDB engine may be lost or function may be called with invalid transaction identifier. 2) If a transaction with the LOAD DATA statement is divided into logical mini-transactions (of the 10K rows) and binlog is rotated, then in rare cases due to the wsrep handler re-registration at the boundary of the split, the last portion of data may be lost. Since splitting of the LOAD DATA into mini-transactions is technical, I believe that we should not allow these mini-transactions to fall into separate binlogs. Therefore, it is necessary to prohibit the rotation of binlog in the middle of processing LOAD DATA statement. https://jira.mariadb.org/browse/MDEV-17262 and https://jira.mariadb.org/browse/MDEV-17243 |
