kevinveenbirkenbachandClaude Fable 5 9bce39009c feat(ci): derive deploy-matrix slots from the workflow chain
cli.meta.ci.slots statically and conservatively counts every job the
CI run spawns outside the deploy matrices (reusable workflows opened
recursively, static matrices multiplied out, dynamic ones estimated,
worst entry-*.yml overhead included) and splits the remaining
256-job run budget between compose/swarm/host by the _SHARES weights,
with a per-mode floor and _SLOT_OVERRIDES pins. INFINITO_MAX_JOBS
defaults to 'auto', resolved per mode in apps.sh; the host workflow
drops its hardcoded cap. --matrix renders the budget as a table.

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).
