This repository hosts reusable CI components (clone steps, build templates, arch-specific runners) and tracks the cross-repo CI optimization effort to reduce duplication across ~50 projects in ~/projects. + +## pypi-wheel-attic template (oleks/ci-scripts#1) + +`manifest.yaml` + `generate.py` render `.woodpecker.yaml` for the fleet of +s390x cross-build repos that share the "single build-and-publish step, inline +`attic watch-store` accelerator, tag-triggered PyPI wheel publish" shape. +Generated files carry a `GENERATED by oleks/ci-scripts — do not hand-edit` +header; edit `manifest.yaml` and re-run `python3 generate.py` instead. + +Not every s390x/arm64 repo fits this template — some (`asyncpg`, +`cryptography`, `fastuuid`, `lightningcss`, `nextjs-swc`, `rollup`, +`onnxruntime`, `scikit-learn`, `scipy`) run a genuinely different "thin +parity-lib publish" pipeline with per-repo Redis sccache wiring and a +pipeline-doctor gate — those differences are load-bearing, not copy-paste +drift, and were deliberately left un-templated (see the scope note atop +`manifest.yaml`). `geesefs-s390x`, `sentry-cli-s390x`, `attic-client-s390x`, +`angie-arm64`, `devpi-arm64`, and `mempalace` are bespoke pipelines (OCI image +publish, binary builds, multi-file workflows) and are also out of scope. + +Verify with: + +``` +python3 generate.py --check # fails if any rendered file is stale +woodpecker-cli lint /.woodpecker.yaml +``` + +## Node-pinning convention (oleks/ci-scripts#5) + +Woodpecker agents advertise `custom_labels` of `{arch, worker}` (e.g. +`arch: arm64, worker: kotkan`). Pipelines pin work to an architecture with the +top-level pipeline `labels:` key, matched against the agent's `arch` label: + +```yaml +labels: + arch: amd64 # or arm64 +``` + +This is the one fleet-wide convention. Two other mechanisms that used to +coexist are retired: + +- `labels: {platform: mermaid}` — an older alias for `arch: amd64` from before + there were multiple amd64 agents. Migrated to `arch: amd64`. +- `backend_options.kubernetes.nodeSelector: {provider: digitalocean}` — a + literal Kubernetes node-label selector (a different mechanism than + Woodpecker agent labels entirely), left over from a single-provider + cluster. Dropped: agent-level `labels:` already routes the pipeline to the + right architecture, so pinning to a specific cloud provider's nodes on top + of that is redundant and brittle if node labels change. + +`backend_options.kubernetes.nodeSelector` with `kubernetes.io/arch` or +`kubernetes.io/hostname` is still valid where a pipeline needs an actual k8s +node-level constraint (e.g. `sentry-cli-s390x` pinning to a specific host) — +that's a different, legitimate use of the mechanism and untouched here. + +## `|| true` ban (oleks/ci-scripts#6) + +Per standing convention, `|| true` is banned repo-wide — it silently swallows +any failure, not just the one it was written for. The fleet's `attic +watch-store` teardown (`kill $ATTIC_PID && wait $ATTIC_PID || true`) is +converted to explicit exit-code handling that still tolerates the benign case +(the backgrounded `attic watch-store` process exiting non-zero after being +killed) without masking anything else: + +```yaml +- if ! kill $ATTIC_PID 2>/dev/null; then echo "attic watch-store already exited"; fi +- if ! wait $ATTIC_PID 2>/dev/null; then echo "attic watch-store exited non-zero after kill (expected)"; fi +``` diff --git a/generate.py b/generate.py new file mode 100644 index 0000000..364dbf2 --- /dev/null +++ b/generate.py @@ -0,0 +1,146 @@ +#!/usr/bin/env python3 +"""Render .woodpecker.yaml for the pypi-wheel-attic fleet family. + +GENERATED files carry a "do not hand-edit" header; edit manifest.yaml instead +and re-run this script.
