Hi all,

I'm sorry, I planned to test this time, but it failed. Any hint what's
wrong? Or can anybody test this patch?

$ . oe-init-build-env

.../build $ bitbake ltp
ERROR: Error importing OE modules: module 'bb.parse' has no attribute
'vardepsexclude'
ERROR: Unable to parse
/home/pvorel/install/src/openembedded/bitbake/lib/bb/parse/ast.py
Traceback (most recent call last):

      layerid, fragment_name = f.split('/', 1)
	      ^^^^^^^^^^^^^^^^^^^^^^
		  ValueError: not enough values to unpack (expected 2, got 1)

FYI I also plan to get rid of some patches posted.

* 0001-Add-__clear_cache-declaration-for-clang.patch
It's wrong, I'd like to replace it with:
https://patchwork.ozlabs.org/project/ltp/list/?series=477319&state=*

* 0001-syscalls-semctl08-Skip-semctl08-when-__USE_TIME64_RE.patch
I posted a review, hopefully we get a feedback from other developers
soon.

* 0001-Remove-OOM-tests-from-runtest-mm.patch
Is it really needed to drop these tests?

BTW for those who run LTP: kirk might be interesting tool to use:
https://github.com/linux-test-project/kirk

We also bundle it in LTP as a submodule:
https://github.com/linux-test-project/ltp/blob/master/.gitmodules

It's also in pypi:
https://pypi.org/project/kirk/

I see in meta/lib/oeqa/runtime/cases/ltp.py the deprecated
/opt/ltp/runltp is still being used. We want to remove it (not sure
when, but it will happen sooner or later). Any change somebody would
submit a patch to switch to kirk?

Kind regards,
Petr

Are you setting OE_FRAGMENTS to something in a config file? It
shouldn't traceback like this so that is a bug but something is
triggering it...

I did send some questions and had some discussion on kirk a while ago.
Quite simply, it isn't useful/interesting to Yocto Project.

What we want to test with is our images and our kernel, as we build it.
kirk, as far as I understand it has gone a different route where there
isn't really any userspace left and it simply tests against a kernel
binary. We'd no longer be testing our build artefacts but some more
artificial construct.

We're trying to test what we build. You're trying to test the kernel
for regressions. They're two different things.

I totally understand why you've gone that direction with kirk but I
also did spell out at the time that it wasn't something which really
fits in with the way we run tests, or what we actually aim to test. I
was told at the time that basically, nobody is interested in what we
want/do.

It is more likely that when you drop runltp, we'll just have to drop
ltp. Sorry :(. I did explain this at while ago :/.

I did also flag the issue to our own wider community but nobody has
stepped up to do anything about it. I've way too many other things to
work on so it is very unlikely I have any time to look at it.

Cheers,

Richard

No, simple clone and the 2 commands above. I'll later try it again on fresh
git clone.

I see your points [2] [3].

I don't understand "any userspace left and it simply tests against a kernel
binary". LTP tests are mostly focused on the kernel (+ it's modules). And you
can run individual tests by just executing them (+ handle environment variables)
or use runltp or use kirk. The executor does not matter that much. In the end we
at SUSE also test with LTP our built image :). (LTP is used by mainline folks
and by distro folks).

FYI although kirk is meant to be run on the host, doing a different connections,
it can also be run on SUT. Sure, there is then python3 dependency on SUT
(heavier than shell + it's dependencies), but still kind of runltp replacement.

It's a question if any of the users really need LTP. If yes, you could vendor
runltp.

Or, write a simple script which parses the content of the runtest files and
execute them. FYI for part of openSUSE testing we still use our custom openQA
runner which does exactly this. It would be very light: -d and -r can be
replaced by TMPDIR and LTPROOT, -I is supported by all tests. The only missing
thing will be generating of results (if you really need it, I'd recommend kirk
and it's JSON output).

The reason we go to kirk + ltx is that in the future we plan to get rid of
runtests, replace them with metadata info (that will allow many things [4],
but you were Cc at the discussion [5]). Once this happen, runltp (or any custom
script / framework runner) will be broken. But this likely take long time.

If you could share the repo/branch you cloned (poky?) I'd appreciate it
as I did try and reproduce that and couldn't. I will write some patches
to improve the code/error regardless as that much is clear from the
failure. It really shouldn't fail like that, it is embarrassing :/.

Sorry, I'm not really being clear. The Yocto Project is in the middle
of some huge changes and I'm struggling with those. Equally, I did want
to at least given some response to your upgrade which is appreciated.

I guess we're one of the few ltp users with a cross environment. We
have a way to launch target images under emulation and our own methods
for controlling them and transferring files. We do all this without
special permissions or access other than ability to use kvm. As such we
liked being able to just run runltp on the target in the environment we
already have.

kirk, at least as I understand it, wants to do much of this for itself.
That means we end up with two ways of running the target emulation
which may or may not match. We'd much prefer just having one so we
either have issues there or we do not but our test environment is
consistent across all tests.

We'd appreciate and be able to use the json output, we already have
json output for most of our other tests. Beyond that, as you say, we
don't really need much beyond what runltp does though. kirk brings with
it a number of things we definitely do not want (as mentioned above). I
don't know if we can avoid those or not.

Right, using a vendored runltp would just buy us a small amount of time
so likely isn't a long term viable solution sadly. I'd consider it if
it were but it doesn't seem a good investment of time.

As I wrote previously, kirk is possible to be used as nearly drop-in runltp
replacement run on the SUT. It's not the intended use-case (we aim it to be run
on host), but still supported use case.

I would say adopting kirk in minimalistic way (or identify what you need and
it's still missing) would be sure safer in a long term.

Which revision/branch of bitbake repo are you using? Note that bitbake
and oe-core repositories are tightly coupled, and if branches are
different, or branches are same but one is behind the other, you will
get errors such as above, e.g. "ERROR: Error importing OE modules:
module 'bb.parse' has no attribute 'vardepsexclude'" is pretty much
saying that oe-core is expecting something bitbake on your machine
doesn't have.

Just to be clear, try cloning git://git.yoctoproject.org/poky which
contains both OE-Core and bitbake. This does look like a bitbake/oecore
version mismatch. I am curious which bitbake version that is? Was it
distro provided?

Richard

I'm sorry for wasting your time, my fault.  I used
git://git.openembedded.org/openembedded-core.git with
git://git.openembedded.org/bitbake.git, which was outdated 2024-09-25:
29e67acb8 ("tests/parse: Add test for unclosed functions")
I forget there are two repos. But lesson learned :).
And thanks for pointing out poky repo.

Kind regards,
Petr

As chance would have it, poky repo is soon discontinued, and everyone
will be using separate repos. Bitbake-setup will help somewhat with
avoiding the mismatches, but bitbake should probably have checks that
it isn't used with a wildly mismatching layer metadata.

Maybe add an equivalent of LAYERSERIES_COMPAT declaration to bitbake
itself, so it doesn't just check that the layers are matching, but
also that they match bitbake?

Ah, there is such a check in meta/classes-global/sanity.bbclass:

    # Check the bitbake version meets minimum requirements
    minversion = d.getVar('BB_MIN_VERSION')
    if bb.utils.vercmp_string_op(bb.__version__, minversion, "<"):
        status.addresult('Bitbake version %s is required and version
%s was found\n' % (minversion, bb.__version__))

The check seems to be happening later than the parse problem you've
encountered (which is triggered by addpylib statement in
meta/conf/layer.conf), and so it would be good to do something similar
as early as possible. I'll prototype a patch.
