MDEV--15609 engines/funcs.crash_manytables_number crashes with error 24
(too many open files)
MDEV-10286 Adjustment of table_open_cache according to system limits
does not work when open-files-limit option is provided
Fixed by adjusting tc_size downwards if there is not enough file
descriptors to use.
Other changes:
- Ensure that there is 30 (was 10) extra file descriptors for other usage
- Decrease TABLE_OPEN_CACHE_MIN to 200 as it's better to have a smaller
table cache than getting error 24
- Increase minimum of max_connections and table_open_cache from 1 to 10
as 1 is not usable for any real application, only for testing.
The MySQL tests for TokuDB are divided into common tests and tests specific to a particular MySQL distribution. The tests that are common for all MySQL distributions can be found in the svn:tokudb/mysql/tests/mysql-test directory. The tests that are specific to a particular distribution can be found in that distribution's mysql-test directory. For example, tests that are specific to MySQL 5.5.21 are found in the svn:tokudb/mysql.com/mysql-5.5.21/mysql-test directory. When we run tests on a particular MySQL distribution, we run the union of the common tests and the tests that are in that distributions mysql-test directory. The union is formed by overlaying the common tests with the distribution specific tests. Here is an example. There are a bunch of alter table tests in that should be common to all MySQL distributions. These tests are in the svn:tokudb/mysql/tests/mysql-test/suite/tokudb.alter_table directory. However, the ai_di.test has behaviour that is different on MySQL 5.5 than previous MySQL distributions. There is another version of this test in the MySQL 5.5.21 source directory. This version replaces the common test since it has the same test name. It is easy to disable a test. Just add the test name to the "disabled.def" file in the test directory. We use the run.mysql.tests.bash script from the mysql/scripts directory to run the tests.
