kevinveenbirkenbachandClaude Opus 5 61f3fe05fb refactor(ci): extract the per-distro loop SPOT
The serial distro loop (shuffle, time budget, fast-fail skip, exit on the first failing distro) lived inline in scripts/tests/deploy/ci/all.sh and was therefore reachable only from the compose and host deploys. Swarm and guide have to iterate distros with the same semantics, so the loop moves into scripts/tests/deploy/distros.sh and takes the per-distro command as "$@".

ci/all.sh keeps the app-level preamble and execs the loop with the new ci/one.sh, which resolves the CI image and dispatches to the per-app override or dedicated.sh.

Image resolution leaves the loop as well: scripts/meta/resolve/image/ci.sh renders the reference through cli.meta.ci.image_ref instead of respelling ghcr.io/... locally, which meta/distros.yml declares as the single source.

The two CI time knobs are declared in default.env instead of being repeated as literals, so no caller has to invent a budget.

Three paths are dropped as dead: the empty budget that disabled the limit, the failed counter that could only ever print 0, and the branch for an unset deadline.

Both new scripts are pinned by contract tests. Those tests clear BASH_ENV because the test container exports it as the env loader, which would otherwise re-inject every stripped key and make the assertions pass for the wrong reason.

utils/env 📐

This directory hosts the Python implementation behind make dotenv. For the general rules that govern READMEs in code directories see documentation.md. For the per-variable defaults that this code consumes see default.env.

Purpose 🎯

The package converts the committed default.env plus a small runtime context into the gitignored .env at the repo root. Every module here belongs to one of four roles: parse, resolve, orchestrate, write.

Structure 🗂️

File Role
parser.py Read default.env into (values, comments) tuples.
runtime.py Resolve host-context lookups (disk, RAM, hostname, GHA/Act flags, /proc/version, helper-script invocation).
builder.py Thin orchestrator that defines EnvBuilder, BuildContext, and build_env(). Walks the handler registry.
writer.py Serialise an EnvBuilder into a docker-compose-compatible .env on disk.
handlers/ One module per dynamically-computed variable. See handlers README.

The CLI entry point lives at __main__.py under cli/meta/env/. Shell consumers source load.sh under scripts/meta/env/.

File Naming 🏷️

  • Module names MUST stay lowercase snake_case.
  • Pure passthrough or simple parser/writer helpers MUST live directly under utils/env/.
  • Per-variable computation MUST live under handlers/ (see handlers README for the naming convention used there).
  • Test files live in tests/unit/utils/env/ and mirror the module name with a test_ prefix.

Import Rules 🔗

  • parser.py, runtime.py, and writer.py MUST NOT import from builder.py or handlers/.
  • builder.py MUST NOT import individual handler modules; it MUST go through the ORDERED_HANDLERS list exposed by handlers/__init__.py.
  • Handler modules MUST NOT import each other (see handlers README).
