The 10 GB, LRU-evicted, PR-scoped Actions cache was being thrashed - the
docker simulator buildx layers (~6 GiB), plus per-PR ccache and apt-archive
writes whose keys never hit - which kept evicting the shared ccache, while
the apt mirror timed out often enough to break PR CI. Move the heavy caches
to ghcr (free, separate pool) and make PR runs read-only against the Actions
cache.
apt dependencies from prebuilt ghcr .deb bundles
- ci-deps-image.yml resolves each package list under .github/ci-deps/ into
its .deb closure and publishes ghcr.io/<owner>/wolfssl-ci-debs:<tag> in
two tiers: <ver>-minimal (make-check family) and <ver>-full (interop
superset), for ubuntu-22.04 and 24.04.
- install-apt-deps gains a ghcr-debs-tag input: pull the bundle and install
offline (--no-download) so the apt mirror is never on the PR critical
path. Any failure (bundle missing/not public/incomplete) falls through to
the existing apt path, so it is always safe to set.
sim-test buildx layers to a shared ghcr registry cache
- the 7 docker simulator workflows switch from cache-to: type=gha to
ghcr.io/wolfssl/wolfssl-sim-cache:<scope>. cache-from reads on every run
(anonymous); cache-to writes only on the weekend cron and manual
workflow_dispatch. Per-distinct-image tags and de-duplicated writers keep
parallel matrix jobs from racing on one ref.
ccache: PRs read, the schedule writes
- ccache-setup gains read-only: PR runs restore the shared master-scoped
cache but never upload; schedule/push runs refresh it. Wired across
os-check (linux + macOS), pq-all, smoke-test and the 12 small make-check
workflows.
- parallel-make-check.py gains --build-only (compile every config, skip the
test phase) so weekday-morning seed crons warm the cache PR runs consume.
artifact retention capped at 7 days on the failure-log/result uploads that
previously defaulted to 90.
ONE-TIME SETUP: after their first publish, make the ghcr packages
wolfssl-ci-debs and wolfssl-sim-cache PUBLIC so anonymous pulls work from PR
(including fork) runs; until then everything falls back cleanly.
GitHub Actions now emits "Node.js 20 actions are deprecated" warnings:
actions are forced to Node.js 24 by default starting 2026-06-16, and
Node.js 20 is removed from the runners on 2026-09-16. Update every
JavaScript action referenced by the workflows and the local composite
actions to the lowest release that runs on Node.js 24:
actions/checkout v4 -> v5
actions/checkout (SHA pin) v4.1.7 -> v5
actions/upload-artifact v4 -> v6 (v5 still Node.js 20)
actions/download-artifact v4 -> v7 (v5/v6 still Node.js 20)
actions/cache[/restore|/save] v4 -> v5
actions/setup-python v5 -> v6
actions/github-script v7 -> v8
docker/setup-buildx-action v3 -> v4
docker/build-push-action v5 -> v7 (v6 still Node.js 20)
docker/login-action v3 -> v4
microsoft/setup-msbuild v2 -> v3
open-watcom/setup-watcom v0 -> v1
Actions already running on Node.js 24 (jwlawson/actions-setup-cmake,
shogo82148/actions-setup-perl, msys2/setup-msys2, dorny/paths-filter)
are left unchanged. These bumps are runtime-only; no workflow uses an
input or output removed by the new majors, and v4-format artifacts
remain compatible across the upload v6 / download v7 backends.
