When a nightly build is started that pushes the version file to the
branch it was doing so only at the end of the build, causing the push
to fail if something else got merged in between.
Push the version file early by generating it the same way it would be
generated by the run_sdk_container/bootstrap_sdk_container scripts.
In the case of the SDK the version file gets the same version for the
OS and the SDK. Add some explanations about the version formats. Note
that the scripts will still rewrite the file but it should be a no-op.
The coreos/portage refs were allowed to be empty strings but the way
the function was run from Groovy the lack of quoting caused the empty
strings to be missing parameters.
Since the two parameters are meant to be optional, support omitting
them.
The pipeline created two tags if an SDK was built, one for the SDK and
one for the OS build (which was a free-standing tag or a local state
that was equivalent to the existing tag of the same name). The
nightlies created update commits on the main branch, even if no change
was done, and on the release branches we lacked these commits.
Create the release tag in the nightly SDK bootstrap already and reuse
it for the nightly OS build. Instead of local state, checkout the
existing tags explicitly. Extend the nightly update commit logic to
cover release branches and detect if we can skip building because no
changes were done.
This change has sdk_bootstrap update the origin branch when run from the
main branch, updating the SDK and OS version in 'main' for each SDK
bootstrap build.
Release / maintenance branches have the SDK version set in the
versionfile at release time. But main is never updated.
Updating the versionfile in main when a new SDK is built ensures that
dev branches based on main will also use the correct SDK version (e.g.
in subsequent CI builds).
ci-automation builds on the SDK container and simplifies CI automation
build tasks (SDK bootstrap, SDK container, packages, image, VMs).
See ci-automation/README.md for a brief introduction.
