With view protocol collation_connection is reset in mysql_make_view in the "SELECT * FROM mysqltest_tmp_v" query. In the case of spider/bugfix.mdev_33434, it is reset to latin1_swedish_ci, with the latin1 charset. This results in no conversion needed since it is the same as character_set_client and the corresponding argument in the udf remains unchanged, with "dummy" srv value. Thus the reported error is 1477: 'The foreign server name you are trying to reference does not exist. Data source error: dummy' Without view protocol, the character_set_connection ucs2 setting in the test survives, and the conversion results in empty connection parameters, and the reported error is 1429 ER_CONNECT_TO_FOREIGN_DATA_SOURCE This failure is irrelevant to the test, or to spider at all. Therefore we disable view protocol for the statement.

MariaDB: The innovative open source database
MariaDB was designed as a drop-in replacement of MySQL(R) with more features, new storage engines, fewer bugs, and better performance.
MariaDB is brought to you by the MariaDB Foundation and the MariaDB Corporation. Please read the CREDITS file for details about the MariaDB Foundation, and who is developing MariaDB.
MariaDB is developed by many of the original developers of MySQL who now work for the MariaDB Corporation, the MariaDB Foundation and by many people in the community.
MySQL, which is the base of MariaDB, is a product and trademark of Oracle Corporation, Inc. For a list of developers and other contributors, see the Credits appendix. You can also run 'SHOW authors' to get a list of active contributors.
A description of the MariaDB project and a manual can be found at:

Getting the code, building it and testing it
Refer to the following guide: https://mariadb.org/get-involved/getting-started-for-developers/get-code-build-test/ which outlines how to build the source code correctly and run the MariaDB testing framework, as well as which branch to target for your contributions.
