MTR .result files currently do not contain output to indicate if a change_user command has been executed in the corresponding .test files. Record change_user command in the following format in MTR output only if disable_query_log is set to false: change_user <user>,<password>,<db>; All new code of the whole pull request, including one or several files that are either new files or modified ones, are contributed under the BSD-new license.
