* docker testing rewrite: bake the image, drop the allowlist, kill the quoting - new `pnpm gha <script>` wrapper. one entry point for running any node script in the GHA-like container; replaces the runtime apt-get + useradd + chown ceremony in `action/utils/docker.ts`. - `action/Dockerfile` bakes ubuntu:24.04 + node 24 + gh + jq + sudo + testuser at uid 1000. `action/docker-entrypoint.sh` remaps to the host uid/gid and `exec`s the requested command — no `bash -c` nesting, no `escapeForDoubleQuotes`. - env passthrough: full `process.env` (+ `.env` via dotenv) flows through `--env-file`, multi-line values via `-e` fallback. drops `EnvFilterMode` / `testEnvAllowList`. - image rebuild is content-hash gated on Dockerfile + entrypoint; volume is versioned by hash so a stale `node_modules` cache from an old image can't poison a new one. - `action/play.ts` slimmed to a CLI; `run()` extracted to `action/utils/runFixture.ts`. drops the `--local` / `PLAY_LOCAL` dual mode in favor of explicit `play:local` / `runtest:local` scripts. - `action/test/run.ts` no longer self-relaunches into docker — that's `gha`'s job now. - `action/test/coverage.ts` `ALWAYS_RUN_ALL` updated to track the new files. - `wiki/docker.md` rewritten (243 → 105 lines). `wiki/action-tests.md`, `wiki/billing.md`, `wiki/adversarial.md`, `README.md`, `AGENTS.md` all updated to drop `--local` / `PLAY_LOCAL` references. verified end-to-end: `pnpm play` runs the default fixture against pullfrog/scratch, exit 0; `sudo unshare --pid` still works inside the container; `pnpm runtest` boots through the wrapper. * gha: address review feedback + 3 related issues found locally review-flagged: - bare `pnpm gha --build` now builds the image and exits 0 (was printing help and exiting 1 — docs claimed it was a valid standalone) - `initVolumeOwnership` skipped when the named volume already exists; saves the ~240ms `docker run … chown` on every warm invocation - `GIT_SSH_COMMAND` gate widened to any `id_*` private key (was hard- coded to `id_rsa`, leaving ed25519-only linux contributors with the default ssh config). dropped `-i` so ssh picks whichever key exists - new `action/.dockerignore` — partial mitigation noted: BuildKit (default since docker 23) only sends files referenced by the Dockerfile (~42B in practice), so the perf concern is mostly hypothetical. file is still worth keeping for `DOCKER_BUILDKIT=0` fallback and as documented intent for future `COPY . .` additions related issues found while validating locally: - `parseArgs` now stops flag-parsing at the first positional (or literal `--`); `pnpm gha test/run.ts --build` previously intercepted `--build` as a gha flag instead of forwarding to `test/run.ts` - new `pnpm gha --clean` command prunes orphan `pullfrog-gha:*` images and `pullfrog-gha-node-modules-*` volumes whose hash doesn't match the current Dockerfile (each Dockerfile/entrypoint edit creates a fresh hash and orphans the prior pair, ~600MB + ~200MB each — without a cleaner they accumulate silently) - `--shell` without a TTY now fails fast with an actionable message before docker is invoked, instead of producing the confusing `the input device is not a TTY` from docker run wiki updated: documents `--clean`, the parseArgs passthrough rule, and a new "Reclaiming disk" section. * gha: fidelity, flexibility, and signal-safety improvements investigated local fidelity vs the real GHA ubuntu-24.04 runner and addressed the gaps that have actually bitten contributors or could. fidelity (image now matches GHA closer): - bake build-essential, wget, xz-utils, file alongside the existing toolset. gh, jq, git, python3, sudo, ssh, build-essential, wget, xz, file, unzip, curl all present. native module builds (node-gyp, any package missing arm64 prebuilts) now work; common agent shell calls don't hit ENOENT - `host.docker.internal:host-gateway` flag wires the host into the container's DNS on linux (macOS Docker Desktop bakes it in). lets scripts that hit a local dev server use `API_URL=http://host.docker. internal:3100` and work identically on both platforms - `--init` makes tini PID 1, fixing signal forwarding during the pre-exec warmup window (Ctrl-C was previously taking up to 10s to tear down because bash-as-PID-1 swallowed the signal) - pnpm version is correctly pinned via the workspace's `packageManager` field — corepack resolves it at install time; verified via the new `--doctor` command flexibility (new affordances): - `pnpm gha --doctor` runs an inside-the-container fidelity audit: os + arch + node/pnpm/python versions, version snapshots of every baked tool, env vars (CI, HOME, TMPDIR), uid/gid, and the host.docker.internal resolution. useful for "works in CI fails locally" or vice versa - `pnpm gha --build --no-cache` busts the docker layer cache when an apt mirror, base image, or external download has changed upstream - entrypoint's `pnpm install` warmup is now wrapped in a `flock` on a file in the shared node_modules volume — concurrent `pnpm gha` invocations (e.g. play in one terminal, runtest in another) serialize their install instead of racing docs: - new "Gaps (known)" section in wiki/docker.md explicitly calling out the things this system can't do yet, including the missing `uses: ./action` semantics gap that `.github/workflows/action-gha-e2e-adhoc.yml` currently fills via GHA only (designing a local `pnpm gha-action <fixture>` is on the roadmap), service containers, parallel-run sharing, and arch differences (arm64 vs amd64) * docs: audit + corrections after testing fronts self-audit pass for stale references and incomplete pointers: - wiki/browser.md: `Docker (node:24)` → `pnpm gha container (ubuntu:24.04)`. the substance was right (chrome not preinstalled) but the base image reference was stale. - wiki/docker.md: the "Permission errors" troubleshooting line claimed the node_modules volume is chowned on every run; now correctly says "owned by the host uid on first creation; warm runs skip the chown" to match the actual behavior after the initVolumeOwnership fix. - wiki/action-tests.md: `API_URL` env-var doc now mentions BOTH paths (`localhost:` from play:local, `host.docker.internal:` from inside the container). Proxy/router recipe now shows both invocations side-by-side instead of saying "must use play:local". - wiki/billing.md: same dual-recipe update for the loop-including-the- action proxy walkthrough. - gha.ts header: expanded the usage block to include --clean / --doctor / --no-cache / --shell-TTY, added the host.docker.internal note, and pointed at wiki/docker.md for design rationale. self-document check: a future agent landing on this code can answer "how do I run a fixture / debug in shell / add a tool / diagnose fidelity / reach a local dev server" purely from gha.ts header + wiki/docker.md without spelunking through the entrypoint or git history.
