The problem is that relying on the output of the 'ls' command is not
portable as its behavior is not the same between systems and it might
even not be available at all in (Windows).
So I added list_files that relies on the portable mysys library instead.
(and also list_files_write_file and list_files_append_file,
since the test was using '--exec ls' in that way.)
Bug#31610 Remove outdated and redundant tests:
partition_02myisam partition_03ndb
Bug#32405 testsuite parts: partition_char_myisam wrong content
and cleanup of testsuite
- remove/correct wrong comments
- remove workarounds for fixed bugs
- replace error numbers with error names
- exclude subtests from execution which fail now because of
new limitations for partitioning functions
- remove code for the no more intended dual use
fast test in regression tests/slow test in testsuite
- analyze and fix problems with partition_char_innodb
- fix problems caused by last change of error numbers
- Introduce error name to error number mapping which makes
maintenance after next error renumbering easier
