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.
Replace the one-runner-per-configuration matrices across the
make-check workflow family with a generic pooled runner,
.github/scripts/parallel-make-check.py. Each workflow keeps its
configuration list as JSON next to the invocation; one runner (or a
small fixed set of shards, balanced by measured per-config minutes)
builds every config in its own out-of-tree (VPATH) build directory off
a single checkout/autogen, on a pool of one-per-CPU worker threads,
longest first. Concurrent checks are isolated with bubblewrap network
namespaces, compilations are cached with ccache, the first failure
aborts the rest (fail-fast, with --no-fail-fast to run everything),
and per-config timings plus pool efficiency land in the step summary.
Failure logs upload as artifacts. smoke-test.yml is likewise reworked
into a single pooled job that runs its nine configs on one runner.
Converted workflows (runner jobs per full pass):
os-check.yml 101 -> 8 (92 Ubuntu configs -> 4 shards;
the macOS matrix, the user-settings jobs and
the standalone
macos-apple-native-cert-validation.yml fold
into one macOS runner; Windows unchanged)
pq-all.yml 21 -> 2 shards
disable-pk-algs.yml 15 -> 1
wolfCrypt-Wconversion.yml 11 -> 1
trackmemory.yml 7 -> 1
cryptocb-only.yml 8 -> 1 (incl. the two new SHA512 entries)
multi-compiler.yml 6 -> 1
smallStackSize.yml 6 -> 1
multi-arch.yml 6 -> 1
async.yml 5 -> 1
psk.yml 5 -> 1
no-malloc.yml 3 -> 1
wolfsm.yml 3 -> 1
opensslcoexist.yml 2 -> 1
Measured against current upstream passing runs (job execution time,
queue excluded): ~200 runner jobs / ~374 runner-minutes per full pass
become 23 jobs / ~168 runner-minutes, with more coverage than before.
multi-arch's old matrix combined an "include" list of four
architectures with an "opts" axis; GitHub's include-merge rules made
each arch entry overwrite the previous one, so only the armel
combinations actually ran. The pooled list restores the intended
aarch64/armhf/riscv64 coverage (23 combinations; riscv64 x sp-math is
omitted as invalid - configure rejects sp-math without SP, and
--enable-riscv-asm, unlike --enable-sp-asm, does not bring SP in).
Out-of-tree build fixes this depends on:
- Makefile.am: symlink the read-only test data (certs/, tests/ config
files, sniffer captures and helpers, examples/crypto_policies,
input, quit) into the build tree via a BUILT_SOURCES stamp, removed
again in distclean-local. ChangeToWolfRoot() and the script tests
resolve everything relative to the working directory, so out-of-tree
make check and make distcheck now pass.
- scripts/multi-msg-record.py: locate the client binary from the build
tree working directory rather than the script's source directory.
- configure.ac + wolfssl/include.am: run
support/gen-debug-trace-error-codes.sh from $srcdir; it reads the
error-code headers from the source tree and generates into the build
tree.
- tests/swdev: a WOLFBUILD variable points the sub-make at the build
tree for the configure-generated headers (wolfssl/options.h,
wolfssl/version.h); the in-tree-only guards are dropped.
Portions of PR #10649 are incorporated: the cross-platform
ccache-setup composite action, repository_owner gates on check-headers
and check-source-text, the docs-only paths-ignore on os-check, and the
libspdm timeout bumps.
