Yesterday two PRs (#9724 llama.cpp bump, #9731 llama-cpp-darwin
consolidation) merged 11 seconds apart. Both shared the same
backend.yml concurrency group (ci-backends-refs/heads/master-...) due
to "${{ github.head_ref || github.ref }}" — empty head_ref on push
events falls through to the static refs/heads/master. With
cancel-in-progress: true that meant the second merge cancelled the
first's in-flight backend builds. The first PR's CI never finished;
the second PR only touched CI files so its run was a no-op.
Two changes per workflow:
- group: replace "${{ github.head_ref || github.ref }}" with
"${{ github.event.pull_request.number || github.sha }}". On PRs
this groups by PR number (same as before, just keyed on number not
branch name); on push events it groups per-commit, so two master
pushes never share a group.
- cancel-in-progress: gate on github.event_name == 'pull_request' so
rapid pushes to a PR still cancel old runs (newer push wins) but
master pushes never cancel each other.
Trade-off vs alternatives:
- Merge queue would also solve this and additionally test the merged
commit before it lands. Heavier process change; out of scope here.
- Allowing per-commit master concurrency means two simultaneous master
runs may overlap and race on tag pushes, but each commit's manifest
digest is unique and the registry is last-writer-wins on tags —
newer commit's tag overwrites older.
Applied to 11 workflows that share the same concurrency pattern:
backend.yml, backend_pr.yml, image.yml, image-pr.yml, lint.yml,
test.yml, test-extra.yml, tests-e2e.yml, tests-aio.yml,
tests-ui-e2e.yml, generate_intel_image.yaml.

* feat(ci): allow routing apt traffic through an alternate Ubuntu mirror
Adds opt-in APT_MIRROR / APT_PORTS_MIRROR knobs to all Dockerfiles, the
Makefile, and CI workflows so we can fail over to a non-canonical Ubuntu
mirror when archive.ubuntu.com / security.ubuntu.com / ports.ubuntu.com
are degraded (recently observed: multi-day DDoS against the default pool).
Defaults are empty everywhere — behavior is unchanged unless a mirror is
configured. To enable in CI, set the repo-level GitHub Actions variables
APT_MIRROR (and APT_PORTS_MIRROR for arm64 builds). Locally:
make docker APT_MIRROR=http://azure.archive.ubuntu.com
A small POSIX-sh helper in .docker/apt-mirror.sh rewrites both DEB822
(/etc/apt/sources.list.d/ubuntu.sources, Ubuntu 24.04+) and the legacy
/etc/apt/sources.list before the first apt-get update. Dockerfile stages
load it via RUN --mount=type=bind, so there is no extra layer and no
cache invalidation when the script is unchanged. Reusable workflows also
rewrite the runner's own /etc/apt sources before any sudo apt-get call.

* ci(apt-mirror): default to the Azure mirror, visible in the workflow source
Bakes Azure (http://azure.archive.ubuntu.com / http://azure.ports.ubuntu.com)
in as the default for both Docker builds and runner-side apt — rather than
hiding the URL behind a GitHub Actions repo variable that's not visible
from the source tree.
A new composite action at .github/actions/configure-apt-mirror is the
single source of truth for runner-side rewrites. Five standalone
workflows (build-test, release, tests-e2e, tests-ui-e2e, update_swagger)
just `uses: ./.github/actions/configure-apt-mirror`.
Three workflows (image_build, backend_build, checksum_checker) keep an
inline bash rewrite, because they install/upgrade git via apt *before*
the checkout step (so the local composite action isn't loadable yet).
The Azure URL is visible in those files too.
The `apt-mirror` / `apt-ports-mirror` inputs of the reusable workflows
keep their now-Azure defaults — they still feed the Docker build-args
block in addition to the inline runner-side rewrite. Callers (image.yml,
image-pr.yml, backend.yml, backend_pr.yml) drop the previous
`vars.APT_MIRROR` plumbing and rely on those defaults.

* ci(apt-mirror): drop Force Install GIT, consolidate on the composite action
The PPA git upgrade ran add-apt-repository ppa:git-core/ppa, which talks
to api.launchpad.net — also part of Canonical's infrastructure and
currently returning HTTP 504. The Azure mirror only covers
archive.ubuntu.com / security.ubuntu.com / ports.ubuntu.com, not PPAs.
The system git that ubuntu-latest already ships is sufficient for
actions/checkout and the build pipeline, so just drop the upgrade. With
that gone, the apt-before-checkout constraint disappears too — all three
holdouts (image_build, backend_build, checksum_checker) can now switch
to ./.github/actions/configure-apt-mirror like the other five.
Net: 0 inline apt-mirror blocks, all 8 workflows route through the
composite action.

core/http/app_test.go had grown to 1495 lines exercising three concerns at
once: HTTP-layer integration, real-backend inference (llama-gguf, tts,
stablediffusion, transformers embeddings, whisper), and service logic that
already has unit-level coverage. Each PR paid for 6 backend builds plus
real-model downloads to satisfy a single suite.
Reorg per layer:
- app_test.go (1495 -> 1003 lines) drives the mock-backend binary only.
Kept: auth, routing, gallery API, file:// import, /system, agent-jobs
HTTP plumbing, config-file model loading. Deleted real-inference specs
(llama-gguf chat, ggml completions/streaming, logprobs, logit_bias,
transcription, embeddings, External-gRPC, Stores duplicate, Model gallery
Context). Lifted Agent Jobs out of the deleted Stores Context.
- tests/e2e-backends/backend_test.go gains logprobs, logit_bias, and
no-first-token-dup specs (the latter folded into PredictStream). Two
new caps gate them so non-LLM backends opt out.
- tests/e2e-aio/e2e_test.go gains a streaming smoke under Context("text")
to catch container-level streaming regressions.
- tests/models_fixtures/ removed; all fixtures referenced testmodel.ggml.
app_test.go now writes per-Context inline mock-model YAMLs.
CI:
- test.yml + tests-e2e.yml gain paths-ignore (docs/, examples/, *.md,
backend/) so docs and backend-only PRs skip them. test.yml drops the
6-backend Build step plus TRANSFORMER_BACKEND/GO_TAGS=tts; tests-apple
drops the llama-cpp-darwin build.
- New tests-aio.yml runs the AIO container nightly + on workflow_dispatch
+ master/tags. The tests-e2e-container job moved out of test.yml so PRs
no longer pay AIO cost.
- New tests-llama-cpp-smoke job in test-extra.yml runs on every PR with
no detect-changes gate; pulls quay.io/go-skynet/local-ai-backends:
master-cpu-llama-cpp (no build on PR) and exercises predict/stream/
logprobs/logit_bias against Qwen3-0.6B. This is the PR-acceptance
real-backend gate after AIO moved to nightly. The path-gated heavy
test-extra-backend-llama-cpp wrapper appends the same caps so it
exercises the moved specs when the backend actually changes.
Makefile:
- Deleted test-models/testmodel.ggml (the wget chain), test-llama-gguf,
test-tts, test-stablediffusion, test-realtime-models. test target
drops --label-filter, HUGGINGFACE_GRPC, TRANSFORMER_BACKEND, TEST_DIR,
FIXTURES, CONFIG_FILE, MODELS_PATH, BACKENDS_PATH; depends on
build-mock-backend. test-stores keeps a focused entry point and depends
on backends/local-store. clean-tests also clears the mock-backend
binary.
Net per typical Go-side PR: ~25min (6 backend builds + tests + AIO) +
~8min e2e drops to ~5min mock-backend test + ~8min e2e + ~5-10min
llama-cpp-smoke (image pulled). Docs and backend-only PRs skip the
always-on workflows entirely.
