[PATCH 0/3] Various improvements of the Isar testsuite

[PATCH 0/3] Various improvements of the Isar testsuite

['Felix Moessbauer' via isar-users]

The probably biggest improvement is to fully switch to cross build (p3).
There should really be no reason to build a large set of targets in
emulated mode, as the cross compile feature in Isar is mature and stable.

All patches of this series work standalone as well. Feel free to also
just partially apply them.

Best regards,

[PATCH 1/3] testsuite: compress sdk with zstd to speedup dev test

['Felix Moessbauer' via isar-users]

We only change it in the dev test, as this test is expected to finish as
quickly as possible. By that, we get even better test coverage, as other
tests still use xz compression.

[PATCH 2/3] testsuite: disable qemumipsel-bullseye tests in rootless mode

['Felix Moessbauer' via isar-users]

The pam + adduser combination of qemumipsel on bullseye does not work in
unprivileged user namespaces. By that, no users can be added to the
image. This results in the following error during do_rootfs_install:

 chfn: PAM: System error
 adduser: `/bin/chfn -f systemd Network Management systemd-network' returned error code 1. Exiting.
 dpkg: error processing package systemd (--configure):
  installed systemd package post-installation script subprocess returned error exit status 1

As this target and distro combination is exotic, we just remove it from
the testsuite if running in rootless mode.

[PATCH 3/3] testsuite: build all targets in cross mode

['Felix Moessbauer' via isar-users]

Cross compiling is supported by isar for a long time, and nowadays also
is the default. Recipes that explicitly don't support cross compilation
are already annotated.

By that, we switch all targets in CI to cross compilation and rename the
now-misleading NoCross test to AllTargets. This gives a massive speedup
on the full CI run, as also the kernels are not compiled via emulation
anymore.

Hi,

Native compilation was originally requested because some packages are not
cross-buildable. Those packages still exist, so I don't think we can drop
native building entirely.

If we keep it, the question is what the proper testing scope should be.
I'm afraid the scope is still full.

So we probably still need to keep both aspects (cross vs. native, and
some-targets vs. all-targets) but split them explicitly in the code. The
exact implementation is open, e.g. separate full-cross / full-native jobs,
or only full with like TEST_CROSS=1.

IIRC Anton has been working on this topic, see [1]. It's better to hear
his opinion as well, he'll be back next week.

Agree. But this should IMHO be done on a per-package level (we can
simply sprinkle a ISAR_CROSS_COMPILE=0 into the recipes of the
incompatible packages). We already do this today. This series is
actually tested on -t alltargets :)

Can't we use the -p cross override, maybe by making it a tristate
(0,1,auto) or something like that? The emulated compilation of the
kernels is *horribly* slow, while we at the same time miss targets by
not running the full-ci because it takes too long.

My hope would be, that we can build the whole testsuite in both cross
and no-cross, whereby the recipes internally fall back to emulation if
cross is not supported.

Both possible. For me it is important to have a fast CI with broad
coverage of targets. Next week I will send out patches to support
bitbake hash equivalence . This makes the testsuite blazing fast when
re-running in most cases. I'm already running this locally for a couple
of weeks and fine-tuning it. And it only needs ~150GB of sstate cache.

Sure! It's not urgent.

PS: feel free to apply patches 1 and 2 already.

Can we maybe just move it into the separate test case, so we can use
@skipUnless / @skipIf macros to just skip this test for rootless?

The original idea of this patchset was to have current "nocross" tests 
still be
tested in cross and noncross modes, but it was 2.5 years ago and no 
cross build
regressions were observed from that time. So now I think that better 
approach
will be to move "nocross" to cross, but create another fully native 
testsuite
with some minimal coverage (for example: all arch, all distros, qemu 
only + 1
real target), so nocross building still can be tested, but without very big
time consumption.

It looks like none of downstreams are using ISAR_CROSS_COMPILE=0 in 
local.conf
currently.

Sounds like a plan. Do you want to implement this - as you already seem
to have a precise idea - or shall I give it a try?

Same on our end.

That should be possible. Will send a v2.

Please give it a try, because I'm afraid it wouldn't be fast from my side.
