Subject: [dpdk-dev] [PATCH v2 1/2] ci: hook to GitHub Actions
Date: Fri,  4 Dec 2020 18:36:21 +0100
Message-ID: <20201204173622.12053-1-david.marchand@redhat.com> (raw)
In-Reply-To: <20201124215700.12126-1-david.marchand@redhat.com>

With the recent changes in terms of free access to the Travis CI, let's
offer an alternative with GitHub Actions.
Running jobs on ARM is not supported unless using external runners, so
this commit only adds builds for x86_64 and cross compiling for i386 and
aarch64.

Differences with the Travis CI integration:
- Error logs are not dumped to the console when something goes wrong.
  Instead, they are gathered in a "catch-all" step and attached as
  artifacts.
- A cache entry is stored once and for all, but if no cache is found you
  can inherit from the default branch cache. The cache is 5GB large, for
  the whole git repository.
- The maximum retention of logs and artifacts is 3 months.
- /home/runner is world writable, so a workaround has been added for
  starting dpdk processes.
- Ilya, working on OVS GHA support, noticed that jobs can run with
  processors that don't have the same capabilities. For DPDK, this
  impacts the ccache content since everything was built with
  -march=native so far, and we will end up with binaries that can't run
  in a later build. The problem has not been seen in Travis CI (?) but
  it is safer to use a fixed "-Dmachine=default" in any case.
- Scheduling jobs is part of the configuration and takes the form of a
  crontab. A build is scheduled every Monday at 0:00 (UTC) to provide a
  default ccache for the week (useful for the ovsrobot).

Changelog since v1:
- changed shell variables value in CI scripts and Travis configuration
  (s/=[^\$]*1/=\1true), this makes it easier for GHA,
- forced compilation as 'default' to avoid random unit tests issues in
  GHA,
- scheduled a run per week on Monday at 0:00 UTC,
- updated the ccache key:
  - no need to depend on the default-library parameter since this
    parameter only impacts the linking of dpdk binaries,
  - the week when the cache is generated is added so that jobs in
    other branches can benefit from a recent cache (mimicking what we had
    for the robot in Travis),
- realigned documentation generation with what is done in Travis:
  generating the doc in all jobs was a waste of resources,
