[Buildroot] [PATCH 0/2] gitlab-ci: fix pipelines with the newer docker image (branch yem/pipelines)

[Yann E. MORIN]

Hello All!

TL;DR: the newer docker image we use in our pipelines uses a newer git
version that is more strict with the ownership of the files in the git
repository checkout, which makes our check jobs fail.

Long story: see the individual commits. ;-)

Regards,
Yann E. MORIN.

[Buildroot] [PATCH 1/2] gitlab-ci: don't use before_script in job templates

[Yann E. MORIN]

When gitlab prepares a job to run, it checks out the repository with a
non-root user, and spawns a container that runs as root, with some UID
mapping that makes the files be owned by root in the container. However,
our pipelines run as a nont-root user.

Commit bde165f7ad (.gitlab-ci.yml: update Docker image to use) updated
the docker image that is used to run in our pipelines.

That new image includes a git version that is stricter about the
ownership of the git tree it is acting in: git aborts in error when the
user running it does not own the repository.

We use `git ls-tree` quite a lot in our check-{flake8,package,symbols}
rules, so they all fail (in various ways).

To fix this, we either need to fix the ownership or tell git to ignore
the situation. In either case, we'll need to run a scriptlet before all
our jobs.

Gitlab-ci allows to provide a global before_script, that is inherited by
all jobs. However, some of our jobs already declare a before_script, and
that would shadow the global before_Scrikpt.

There is no technical reason to do our before_script separately from
the actual script, so we move the code from the before_scripts to the
corresponding scripts.

Yes, there is a newer flake8 too, but there is no new error detected:

[Buildroot] [PATCH 2/2] gitlab-ci: fix pipelines

[Yann E. MORIN]

When gitlab prepares a job to run, it checks out the repository with a
non-root user, and spawns a container that runs as root, with some UID
mapping that makes the files be owned by root in the container. However,
our pipelines run as a nont-root user.

Commit bde165f7ad (.gitlab-ci.yml: update Docker image to use) updated
the docker image that is used to run in our pipelines.

That new image includes a git version that is stricter about the
ownership of the git tree it is acting in: git aborts in error when the
user running it does not own the repository.

We use `git ls-tree` quite a lot in our check-{flake8,package,symbols}
rules, so they all fail (in various ways).

To fix this, we either need to fix the ownership or tell git to ignore
the situation.

It is most probably impossible to change the ownership of the files: we
run as non-root,and the files belong to root (in the container). So
we're stuck.

The alternative, is to do as git suggest, and tell it to ignore the
situation. In a local setup, this woujld be very insecure, but in the
pipelines, this is in a throw-away container, wehre a single user exists
and is running, so we don't care much (if at all).

Add a global before_script that registers the git config to ignore
ownership issues in the buildroot repository; see [0] for the definition
of the CI_PROJECT_DIR variable. Note: unlike what is said in there, and
in [1], the value actually seen in CI_PROJECT_DIR is already prefixed
with CI_BUILDS_DIR (the documentation is unclear about that point).

Hello Yann,

Is "fix pipelines" your WIP patch subject ?
"gitlab-ci: ignore ownership of the git tree" seems better?

Note: I checked if we have the issue using the utils/docker-run directly,
enabling safe.directory is not necessary.

No, I really intended to write "fix pipeline".

Indeed, the subject of a commit log should be a summary of the semantic
change, not of how it is done.

Thanks for the review! :-)
