[Buildroot] [PATCH v5 0/5] gitlab Qemu runtime testing

[Romain Naour]

This new iteration take into account the previous review with
some additional rework [1] [2] [5] [6].

Remove patch already merged.

Based on the Yann's review during the Buildroot Developper meeting
FOSDEM 2020 [2], add a tag in each readme file to easily retrieve
the qemu command line to be used for runtime testing in gitlab.

This tag is used by a post-image script to generate a script
called start-qemu.sh that can be used by users or by a new python
script for running the test in gitlab but only when a Qemu
defconfig is built.

Finally add this new python script to .gitlab-ci.yml.

This series has been tested on Gitlab [3], please ignore the
failing test related to missing host-python3 modules needed by
optee-os package [4].

This new iteration has been tested in gitlab [7].

[Buildroot] [PATCH v5 1/5] board/qemu: add defconfig file name as tag after the qemu command line

[Romain Naour]

This commit add the name of the Qemu defconfig file after each
qemu command line in order to retrieve it easily.

Since a readme.txt can be shared between several Qemu defconfig, we
need at least one qemu command line in readme.txt for each defconfig.

For now, ignore the qemu_arm_vexpress_tz_defconfig since it fail to build
due to python script issue [1]. Anyway the arm vexpress boot is tested
with qemu_arm_vexpress_defconfig.

[Buildroot] [PATCH v5 2/5] board/qemu: add post-image script for gitlab qemu testing

[Romain Naour]

This commit add a post-image script to be used by each qemu
board defconfig in order to generate start-qemu.sh in BINARIES_DIR.
The start-qemu.sh script can be used by Buildroot user to start
Qemu or by a gitlab CI.
start-qemu.sh is not started automatically at the end of the build.

To find the correct qemu command line, we use the second post
script argument which must contain "$(BR2_DEFCONFIG)"

  BR2_ROOTFS_POST_SCRIPT_ARGS="$(BR2_DEFCONFIG)"

The post-image script expect something like
"/path/to/qemu_aarch64_virt_defconfig" in BR2_DEFCONFIG.

Doing a basename allow to retrieve the name of the defconfig
file that should match on on the "tag" previously introduced in
readme.txt files.

The script start-qemu.sh is able to modify the qemu command
line if CI_JOB_NAME defined in the environment. This allow
to disable the graphical output and redirect serial I/Os to
console.

Only sh4/sh4eb needs a special handling by adding
"-serial stdio -display none" instead of "-display none".

[Buildroot] [PATCH v5 4/5] support/scripts/boot-qemu-image.py: boot Qemu images with Qemu-system.

[Romain Naour]

From: Jugurtha BELKALEM <jugurtha.belkalem@smile.fr>

This script is intended to be used by gitlab CI to test
at runtime Qemu images generated by Buildroot's Qemu defconfigs.

This allows to troubleshoot different issues that may be
associated with defective builds by lanching a qemu machine,
sending root password, waiting for login shell and then perform
a shutdown.

This script is inspired by toolchain builder [1] and the Buildroot
testing infrastructure.

Usage: boot-qemu-image.py <qemu_arch_defconfig>

The gitlab CI will call this script for each defconfig build but
only Qemu defconfig will be runtime tested, all others defconfig are
ignored. The script retrieve the qemu command line from start-qemu.sh
script. The start-qemu.sh script is no executed directly since we
want to handle the serial output with pexpect to detect the
shell, enter the password and powerdown the system.
If the script is missing, error out with a message in the log.

The script check is the corresponding Qemu binary (qemu-system) is
available, either built by Buildroot or available from the host.
Some Qemu defconfig must be used with a specific Qemu version (fork)
that is not always available. The script doesn't error out when
qemu-system is missing but a message is added in the log.

Finally, the script start Qemu like it's done for the Buildroot
testing infrastructure (using pexpect).

Note:
We noticed some timeout issues with pexpect when the Qemu machine is
powered off. That's because Qemu process doesn't stop even if the
system is halted (after "System halted"). So the script doesn't error
out when such timeout occure. The behaviour depends on the architecture
emulated by Qemu.

[Buildroot] [PATCH v5 5/5] gitlab.yml.in*: enable Qemu gitlab testing

[Romain Naour]

From: Jugurtha BELKALEM <jugurtha.belkalem@smile.fr>

Used to launch qemu tests for various qemu architectures.
Neverthless to say that this file skips any other job
different from qemu (only qemu configurations are
runtime tested).

Add the log generated by Qemu to the build artefacts.

Overall, I am quite happy with the series. There are just two things
that I am not entirely sure about:

 (1) The logic that tests $CI_JOB_NAME in board/qemu/post-image.sh, to
     test if we are running under Gitlab CI or not. It feels a bit
     hackish to me. Should this magic be there, or instead tweaked by
     the Gitlab CI testing stuff directly ?

 (2) We now generate this start-qemu.sh script in $(BINARIES_DIR), but
     in fact only really use it for Gitlab CI testing. Should we make
     this start-qemu.sh script more prominently useful ? Or should we
     instead not have any start-qemu.sh script, and have the Gitlab CI
     testing logic directly find what the Qemu command line should be ?

That being said, this series has been around for a long time, so unless
I get some feedback on these questions, I'm going to apply it as-is, we
can always improve on top of that later on.

Best regards,

Thomas

True, this is how it's done in toolchain-builder project. But the goal here is
to provide the start-qemu.sh script at the end of the build, even outside of
Gitlab CI.

start-qemu.sh can be used outside of Gitlab CI, I'm regularly using Qemu
defconfig locally and getting the qemu command line from the readme is not
practical. That was the feedback I had from one user on previous iteration.

This series was started by my colleague Jugurtha about one year ago. Since then
toolchains update showed that Qemu runtime testing is necessary otherwise we can
end up with a non working defconfig (see issue with binutils 2.34 and sh4 kernel).

Thanks Yann for the review during the last Buildroot meeting!

Why do you extract the command line, and can't directly run the script?

> +qemu_cmd = line.replace("${IMAGE_DIR}", "output/images")

This would avoid this dance...

> +qemu_cmd = shlex.split(qemu_cmd)

... as well as this one.

And this one can be avoided too if the script is called with PATH
properly set to include ${HOST_DIR}/bin. This should be easy, as this
script is only expected to run from the gitlab-ci pipelines.

Mixing code at the top-level and in a main() is ugly. Mocve everything
to a main (and helper functions if youlike), but don't mix the two.

You would not have to do that if you just called the start-qemu.sh script.

[Buildroot] [PATCH v5 2/5] board/qemu: add post-image script for gitlab qemu testing

[Yann E. MORIN]

Romain, jugurtha, All,

Like Thomas, I'm not too keen on this gitlab-ci knowledge leaking in
there...

I think we can abstract that in the post-build script to just prepare
the two sets of options, the default one (graphical), or the serial-only
case, and store both sets in start-qemu.sh.

Then start-qemu.sh chooses which to use based on ${1}: if it is
'serial-only' (or whatever), then ti uses the serial-only options,
otherwise it uses the graphical options.

I've already hack that: http://code.bulix.org/ip443p-1282035?raw

Of course, whis will require a bit of rewriting in the latter patch that
tries to extract the qemu command line to run it in gitlab-ci, but I've
anyway already replied to that patch (hint: it would just need to call
start-qemu.sh with the new parameter).

I understand this review is coming late, so I'll take on me to apply
those changes and respin the series a bit later today...

Yann E. MORIN.

Extracting the qemu command line in the boot-qemu-image.py allowed to test if at
least one qemu-systemd-<arch> binary is present. Starting start-qemu.sh directly
crash the python script.

csky and or1k defconfig doesn't select any host-qemu and there is none installed
in the Buildroot Docker image used by gitlab CI.

It seems we need to catch the exception while calling pexpect.spawn(qemu_start...)

https://git.buildroot.net/buildroot/tree/support/scripts/boot-qemu-image.py#n22

Or just add this test in start-qemu.sh

Romain
