Fixes the following bugs: Bug #30706: SQL thread on slave is allowed to block client queries when slave load is high Add (innodb|innobase|srv)_replication_delay MySQL config parameter. Bug #30888: Innodb table + stored procedure + row deletion = server crash While adding code for the low level read of the AUTOINC value from the index, the case for MEDIUM ints which are 3 bytes was missed triggering an assertion. Bug #30907: Regression: "--innodb_autoinc_lock_mode=0" (off) not same as older releases We don't rely on *first_value to be 0 when checking whether get_auto_increment() has been invoked for the first time in a multi-row INSERT. We instead use trx_t::n_autoinc_rows. Initialize trx::n_autoinc_rows inside ha_innobase::start_stmt() too. Bug #31444: "InnoDB: Error: MySQL is freeing a thd" in innodb_mysql.test ha_innobase::external_lock(): Update prebuilt->mysql_has_locked and trx->n_mysql_tables_in_use only after row_lock_table_for_mysql() returns DB_SUCCESS. A timeout on LOCK TABLES would lead to an inconsistent state, which would cause trx_free() to print a warning. Bug #31494: innodb + 5.1 + read committed crash, assertion Set an error code when a deadlock occurs in semi-consistent read.
