ci: disable cirrus cache in 32bit arm job
Co-authored-by: Max Edwards <youwontforgetthis@gmail.com>
Add an optional matrix field allowing opt-out of configuring cirrus
GHA cache when not using cirrus runners.
This is not needed for the cirruslabs/[save|restore]-cache actions, as
they automatically fallback based on runner type.
What changed, and why it matters
This commit changes Bitcoin Core's continuous integration (CI) configuration for GitHub Actions. It adds a per-job option to override which cache provider is used for Docker setup, specifically setting a 32-bit ARM job to use GitHub Actions' native cache instead of Cirrus Labs' cache. This is a build-infrastructure tweak with no apparent effect on the Bitcoin software users run, on their funds, or on network security.
No security action required. Treat as routine CI maintenance.
Security signals we found
No strong security signals were identified.
Evidence from the diff
The change is confined to .github/workflows/ci.yml. It introduces an optional matrix.provider field defaulting to needs.runners.outputs.provider, and sets provider: ‘gha’ for the 32-bit ARM CI job. The configure-docker action now receives cache-provider: ${{ matrix.provider || needs.runners.outputs.provider }}. This disables Cirrus cache configuration for the ARM job, likely because that job does not run on Cirrus runners and therefore cannot use Cirrus’s cache backend. The Cirrus save/restore-cache actions are unaffected because they auto-fallback by runner type.
