WL#7083 step 6.4. GTID-violations: User-visible changes for counters of GTID-violating transactions.
This patch introduces the following user-visible changes related to the counters that keep track of the number of ongoing GTID-violating transactions: - Generate error when user tries to change from GTID_MODE=OFF_PERMISSIVE to ON_PERMISSIVE, when there are ongoing GTID-violating transactions using GTID_NEXT=AUTOMATIC. - Generate error when user tries to change from ENFORCE_GTID_CONSISTENCY=WARN or OFF to ON, if there are ongoing GTID- violating transactions. - Generate error when user tries to change from ENFORCE_GTID_CONSISTENCY=OFF to WARN, if there are ongoing GTID- violating transactions. - When debug mode is enabled, the counters are visible as the status variables AUTOMATIC_GTID_VIOLATING_TRANSACTION_COUNT and ANONYMOUS_GTID_VIOLATING_TRANSACTION_COUNT. @mysqld.cc - Two new status variables. @errmsg-utf8.txt - Two new error messages. @sys_vars.h - Three new error conditions.
