arduino.yml's per-core actions/cache layer stored the installed cores and
toolchains (~/.arduino15) - several GB, dominated by the esp32 and mbed
cores - in the 10 GB Actions cache. For esp32 it was also ineffective: the
disk-cleanup step deletes the esp32 toolchain before actions/cache saves it,
so esp32 re-downloaded every run anyway.
- New arduino-cores-image workflow resolves each of the 9 distinct cores and
publishes a tar of ~/.arduino15 + ~/Arduino/libraries to
ghcr.io/<owner>/wolfssl-ci-arduino:<core>. It runs monthly: esp32, the
fastest-moving core, releases ~monthly and the rest far less often.
- New install-arduino-core composite action restores that bundle offline and
verifies the core is present, falling back to `arduino-cli core install`
when the bundle is unavailable - so nothing breaks until the image is first
published and made public.
- arduino.yml calls the action in place of the inline core install and the
actions/cache step.
This takes the flaky espressif / esp8266.com / pjrc.com downloads off the PR
critical path and frees the Actions cache of the largest binaries it held.
The ci-cache-offload work added a ghcr .deb bundle path to
install-apt-deps, making the actions/cache apt-archive layer redundant.
Remove it so no apt-deps-* cache entries are produced. Apt packages now
install either offline from the ghcr bundle (when ghcr-debs-tag is set)
or via plain apt-get with the existing retry/backoff.
- Strip the Compute/Restore/Pre-seed/Collect/Save cache steps and the
cache-hit fast path; drop the now-unused 'cache' input.
- Update callers that passed 'cache': membrowse-onboard, membrowse-report
(and the apt_cache matrix key in membrowse-targets.json), and sssd.
The ghcr offline path and the ccache actions/cache usage are untouched.
Rebasing onto master (which migrated JS actions to Node.js 24 runtimes)
left a few action refs that this branch added in new steps still on the
old major versions. Bring them in line with master:
- ccache-setup read-only restore: actions/cache/restore@v4 -> @v5
- smoke-test / os-check ccache save: actions/cache/save@v4 -> @v5
- ci-deps-image checkout: actions/checkout@v4 -> @v5
- os-check.yml linux shard: add a schedule-gated CCACHE_RECACHE=1 step so
the weekday seed reseeds from clean compiles rather than only accumulating
deltas. This shard manages ccache directly (its own restore/save) and so
was not covered by the ccache-setup composite's reseed.
- install-apt-deps: hardcode the ghcr bundle owner to wolfssl. The bundle is
only published under ghcr.io/wolfssl by ci-deps-image, so fork PRs now read
the public upstream image instead of a nonexistent ghcr.io/<fork>/wolfssl-ci-debs.
- ccache-setup: document that the read-only restore key reuses the save
key shape for symmetry and is never an exact hit by design.
Skoll F3 (a packages-subset-of-bundle CI guard) is deferred to a follow-up;
F4 (release-branch ccache saves) is left as the intended seed-on-schedule /
everything-else-reads model.
Tighten three pieces of documentation to match the implementation; no
behaviour change:
- install-apt-deps (ghcr-debs-tag description): the apt mirror is avoided
only on the successful offline path. The offline install is a single
--no-download install of the whole package set, so any miss (bundle
absent/private/incomplete) falls back to the apt path.
- ci-deps-image header: each bundle is every requested package plus the
dependencies not already present on the matching runner image - tied to
that runner, not a portable/self-contained .deb closure.
- ci-deps-image schedule note: a package missing from the bundle fails the
whole offline install (it is not per-package), falling back to the full
apt path.
- ccache-setup: gate the scheduled-reseed step with
`if: github.event_name == 'schedule'` again. The github context IS
available in a composite action's step-level if: (install-apt-deps
already relies on it), so the earlier $GITHUB_EVENT_NAME workaround and
its comment were based on a wrong premise. The real load failure was the
${{ }} expression in the read-only input description, fixed separately.
- smoke-test.yml: include github.event_name in the concurrency group. The
workflow pushes to master/main and now also runs on a weekday schedule;
both share github.ref on the default branch, so under
cancel-in-progress a seed run and a master push could cancel each other.
The read-only input description embedded `${{ github.event_name ==
'pull_request' }}` as example text. GitHub validates ${{ }} expressions in
an action's input definitions at manifest-load time, where the github
context is not available, so the action failed to load ("Unrecognized
named-value: 'github'", action.yml line 27) and every ccache-setup
consumer died at "Set up ccache" (build library, make check, Compiler
test, Multi-arch test, ...). Describe the expression in prose instead of
embedding it as a live ${{ }} template; the github.* references that
remain are in step with:/run: blocks, where the context is available.
The scheduled-reseed step gated CCACHE_RECACHE with
`if: github.event_name == 'schedule'`, but the github context is not
available in a composite action's step-level if:. The action manifest
therefore failed to load ("Unrecognized named-value: 'github'"), and
every workflow using ccache-setup broke at the "Set up ccache" step
(build library, make check, Compiler test, Multi-arch test, ...).
Gate on the built-in $GITHUB_EVENT_NAME env var in the shell instead,
which keeps the schedule-only reseed behaviour with no caller changes.
The scheduled (cron) refresh restored the prior ccache and recompiled
only the translation units that changed, so unchanged objects were never
rebuilt and the shared cache could drift indefinitely. Set
CCACHE_RECACHE=1 on schedule events - gated inside the ccache-setup
action, so none of the calling workflows change - to force fresh
compiles that re-store every result. PR and push runs are unaffected and
keep their warm hits; only the scheduled jobs pay the full recompile.
- install-apt-deps: the ghcr offline-install path now honors the
no-install-recommends input; it was always installing recommends,
diverging from the regular apt path.
- install-apt-deps: correct the ghcr-debs-tag example to a real tag
(ubuntu-24.04-minimal) - ci-deps-image publishes -minimal/-full
variants, not a bare <ver> tag.
- os-check: fix the schedule header comment - macOS runs --build-only on
the weekday cron to seed its ccache (like the linux shards); only
Windows is skipped on schedule.
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.
