But we save the gtid into GLOBAL@gtid_executed in the case when binlog is disabled. Fix === When @@SESSION.GTID_NEXT == 'UUID:NUMBER', the command 'BEGIN' causes an error 'ER_CANT_DO_IMPLICIT_COMMIT_IN_TRX_WHEN_GTID_NEXT_IS_SET' inside an empty/a non-empty transaction regardless of being binlogless or not, since it causes an implicit commit like other DDLs. And we do not save the gtid specified by GTID_NEXT into GLOBAL@gtid_executed in the case. diff --git a/mysql-test/extra/binlog_tests/gtid_next_begin_caused_trx.test b/mysql-test/extra/binlog_tests/gtid_next_begin_caused_trx.test new file mode 100644 index 00000000000..1459bcdf775 --- /dev/null +++ b/mysql-test/extra/binlog_tests/gtid_next_begin_caused_trx.test @@ -0,0 +1,76 @@ +# ==== Purpose ==== +# +# When @@SESSION.GTID_NEXT == 'UUID:NUMBER', verify that the command +# 'BEGIN' causes an error +# 'ER_CANT_DO_IMPLICIT_COMMIT_IN_TRX_WHEN_GTID_NEXT_IS_SET' inside +# an empty/a non-empty transaction, since it causes an implicit +# commit.
