This allows one to run the test suite even if any of the following options are changed: - character-set-server - collation-server - join-cache-level - log-basename - max-allowed-packet - optimizer-switch - query-cache-size and query-cache-type - skip-name-resolve - table-definition-cache - table-open-cache - Some innodb options etc Changes: - Don't print out the value of system variables as one can't depend on them to being constants. - Don't set global variables to 'default' as the default may not be the same as the test was started with if there was an additional option file. Instead save original value and reset it at end of test. - Test that depends on the latin1 character set should include default_charset.inc or set the character set to latin1 - Test that depends on the original optimizer switch, should include default_optimizer_switch.inc - Test that depends on the value of a specific system variable should set it in the test (like optimizer_use_condition_selectivity) - Split subselect3.test into subselect3.test and subselect3.inc to make it easier to set and reset system variables. - Added .opt files for test that required specfic options that could be changed by external configuration files. - Fixed result files in rockdsb & tokudb that had not been updated for a while. |

=========================
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 ...".
