[PATCH 0/2] Changes to timers Maefile to use shared logic for run_tests and install

[Shuah Khan]

This patch set:

adds ability to run and emit script for tests args to lib.mk.
lib.mk provides a way to override the default RUN_TESTS and
EMIT_TESTS, however in the cases where a test has several
executables that don't require any special args and/or handling
and some that do, overrding will be cumbersome. Add variables
RUN_TESTS_WITH_ARGS, and EMIT_TESTS_WITH_ARGS to enable a test to
run and exmit script for such special executables.

Timers test Makefile is changed to use the shared logic for running
and installing tests.

[PATCH 1/2] selftests: add ability to run and emit script for tests args to lib.mk

[Shuah Khan]

Add ability to run, emit, install tests take arguments to the
shared logic in lib.mk. lib.mk provides a way to override the
default RUN_TESTS and EMIT_TESTS, however in the cases where a
test has several executables that don't require any special args
and/or handling and some that do, overrding will be cumbersome.
Add variables RUN_TESTS_WITH_ARGS, and EMIT_TESTS_WITH_ARGS to
enable a test to run and exmit script for such special executables.

[PATCH 2/2] selftests/timers: change to use shared logic to run and install tests

[Shuah Khan]

Change the timers Makefile to make use of shared run and install
logic in lib.mk. Destructive tests are installed. Regular tests
are emited to run_kselftest script to match the run_tests behavior.

So my make-foo isn't very strong, but no objections from me.

My only thoughts:
1) Would it be better if threadtest can be made to have better
defaults for kselftest so you don't need that extra logic?
2) While I get that TEST_FILES is likely going to be used to copy the
destructive tests over, It feels a little like its being bundled in
with something like data files that tests might need, which seems sort
of hackish. Would TEST_PROGS_EXTENDED or something be more clear and
make more sense?

That would help. But with the patch I just sent I think it's no bother, it's
only a little extra logic and it's only in the timers Makefile.

That doesn't really bother me. You're right that TEST_FILES is originally
intended for data files etc. but I don't think it's a big hack to use it for
other tests that shouldn't be run by default. Still if it bothers you I'm happy
to add a separate variable for it, they are cheap :)

Let's go with a threadtest patch with better defaults. It will emit
scripts logic as well. Awesome. I just saw John's new patch in my
Inbox. Thanks.

Michael,

Could you please make the change from TEST_FILES to TEST_PROGS_EXTENDED
which is definitely better than overloading TEST_FILES?

I think this would probably only change Add Install target patch. You
can send me patch v5 with that change and I will override the next with
your new one. Thanks for doing this.

thanks,

I don't see the point, but I don't care that much.

You shouldn't rebase your next branch, people may have already merged it (like
me). You should apply it as an additional patch on top.

Patch sent.

Yes. If you can change the threadset to run with -t 30 -n 8
in default case, that would make the logic simpler. Can you
send me a patch to do this?

I agree with you on this. TEST_FILES usage is an overload.

You shouldn't need this separate variable. As long as you override RUN_TESTS after you include lib.mk you can include the default value, eg:

override RUN_TESTS := $(RUN_TESTS) ./threadtest -t 30 -n 8 || echo "selftests: threadtest [FAIL]"

I'll test that in the morning and send a proper patch.

How's this look?

Contents of install/timers (same as with your patch):

$ ls install/timers/
alarmtimer-suspend*  clocksource-switch*   leap-a-day*  mqueue-lat*  nsleep-lat*    raw_skew*  set-tai*        skew_consistency*  valid-adjtimex*
change_skew*         inconsistency-check*  leapcrash*   nanosleep*   posix_timers*  set-2038*  set-timer-lat*  threadtest*

And in run_kselftest.sh:

echo ; echo Running tests in timers
echo ========================================
cd timers
(./posix_timers && echo "selftests: posix_timers [PASS]") || echo "selftests: posix_timers [FAIL]"
(./nanosleep && echo "selftests: nanosleep [PASS]") || echo "selftests: nanosleep [FAIL]"
(./nsleep-lat && echo "selftests: nsleep-lat [PASS]") || echo "selftests: nsleep-lat [FAIL]"
(./set-timer-lat && echo "selftests: set-timer-lat [PASS]") || echo "selftests: set-timer-lat [FAIL]"
(./mqueue-lat && echo "selftests: mqueue-lat [PASS]") || echo "selftests: mqueue-lat [FAIL]"
(./inconsistency-check && echo "selftests: inconsistency-check [PASS]") || echo "selftests: inconsistency-check [FAIL]"
(./raw_skew && echo "selftests: raw_skew [PASS]") || echo "selftests: raw_skew [FAIL]"
./threadtest -t 30 -n 8 || echo selftests: threadtest [FAIL]
cd $ROOT
