CI failures like
http://ci.rvm.jp/results/trunk-mjit@phosphorus-docker/3280458 doesn't
provide any useful information, and it doesn't leave a core file in a CI
environment because a test like `Process.kill(:TRAP, $$)` overwrites in
a next run very quickly.
Thus I'd like to keep core files in /tmp.
This patch contains the fowllowing hacks:
(1) Add "--timetable-data=FILE" option for test-all
This option enables to dump timeline event
contains worker, suite, and start/end time.
(2) remove TestJIT in test_jit_debug.rb on parallel test.
it is duplicated test.
(3) move test_jit.rb and test_jit_debug.rb at first
because these two tests are bottleneck of parallel tests.
On my environment, `make test-all TESTS=-j12` reduced the total time
190 seconds -> 140 seconds.
There is a test directory named test/-ext-. Because this directry
starts with a hyphen, we have to cheat test/unit in order for it to
run the tests underneath. TESTS='-- -ext' worked for a long time.
Let's not break that maneuver.
`make test-all TESTS=name` can specify running test files by name.
name can be dirname ('dir/') or a file ('.../test_foo.rb'). This
patch complement `test_` prefix for a test. So we only need to
specify `TESTS=ruby/hash` which means `TESTS=ruby/test_hash.rb`.
tool/test/runner.rb had been copied from test/runner.rb.
test/runner.rb was for `make test-all`, and tool/test/runner.rb was for
`make test-testframework` and `make test-tool`.
But I want to avoid the code clones.
This change makes tool/test/runner.rb support --test-target-dir option
which allows tool/test/runner.rb to run `make test-all`.
Now we can remove test/runner.rb.
for test-all rule, we can specify a file with TESTS option like
`TESTS=test_xxx.rb`. However, we can eliminate last '.rb' suffix
so this patch try with '.rb' suffix if the given path is not available.
