2008-02-29 Matthias Leich ========================= 1. The testsuite "funcs_1" is mostly intended for additional (compared to the common regression tests stored in mysql-test/t) checks of features (VIEWS, INFORMATION_SCHEMA, STORED PROCEDURES,...) introduced with MySQL 5.0. 2. There were some extensions of this suite when new information_schema views were introduced. But in most cases the tests for these views were stored within the regression testsuite (mysql-test/t). INFORMATION_SCHEMA views introduced with MySQL 5.1 ================================================== ENGINES (partially tested here) EVENTS (partially tested here) FILES GLOBAL_STATUS GLOBAL_VARIABLES PARTITIONS PLUGINS PROCESSLIST (full tested here) PROFILING REFERENTIAL_CONSTRAINTS SESSION_STATUS SESSION_VARIABLES 3. Some hints for maintainers of this suite: - SHOW TABLES ... LIKE '<pattern>' does a case sensitive comparison between the tablename and the pattern. The names of the tables within the informationschema are in uppercase. So please use something like SHOW TABLES FOR information_schema LIKE 'TABLES' when you intend to get the same non empty result set on OS with and without case sensitive filesystems and default configuration. - The name of the data dictionary is 'information_schema' (lowercase). - Server on OS with filesystem with case sensitive filenames (= The files 'abc' and 'Abc' can coexist.) + default configuration Example of behaviour: DROP DATABASE information_schema; ERROR 42000: Access denied for user ... to database 'information_schema' DROP DATABASE INFORMATION_SCHEMA; ERROR 42000: Access denied for user ... to database 'INFORMATION_SCHEMA' - Try to unify results by --replace_result $engine_type <engine_to_be_tested> if we could expect that the results for storage engine variants of a test differ only in the engine names. This makes future maintenance easier. - Avoid the use of include/show_msg*.inc. They produce "SQL" noise which annoys during server debugging and can be easy replaced by "--echo ...".
