kevinveenbirkenbachandClaude Opus 5 5b8465260f feat(ci): deploy only the variants a change reaches
An image bump in a provider redeployed every variant of every consumer,
including the variants that switch that provider off and therefore never
deploy the bumped image at all. The diff-derived whitelist now narrows each
affected role to the variants whose own round closure still reaches a seed,
emitted as `role#0,2` selection tokens. That closure is walked on the same
variant-merged services maps the matrix planner builds its rounds from, so the
narrowing follows a parent's variant choice across every generation of the
chain. It covers every auto-derived whitelist: the weekly update PRs,
Dependabot, and any other diff-driven run.

The narrowing never shrinks the matrix on partial information. A seed role
keeps every variant, because its own files changed. A role reached only
through a run_after edge keeps every variant too, because the round closure
does not follow that edge and a role whose hits are empty is therefore
unnarrowed rather than dropped.

A pinned token naming a role the discovery query does not return now warns
instead of aborting the run. The diff-derived whitelist legitimately names
roles the lifecycle envelope filters out, and once it pins variants such a
token would abort every chunk; role names are still checked against roles/
before the run starts, so a typo is caught one layer earlier.

The round's variant merge moves out of the deploy inventory package into
utils/roles/applications/variants.py. The CI selection has to build the same
maps, and importing the deploy package for them pulls in a module that reads
INFINITO_SRC_DIR at import time, which the runner host does not set.

Shared Utilities (utils/)

This directory contains shared Python helpers used by custom modules and plugins.

Purpose

Use utils/ for reusable code that should not be duplicated across:

  • library/ modules,
  • plugins/action/,
  • plugins/filter/,
  • plugins/lookup/.

Typical shared utilities:

  • API clients,
  • validation/conversion helpers,
  • path and configuration helpers,
  • cross-plugin/module domain logic.
  • Shared HTTP(S) connection handler for multiple modules.
  • Common validation or transformation functions for user input.
  • Utility functions for interacting with Docker, LDAP, etc.
  • Grouped helper packages such as utils/domains/ for related domain logic.

Design Guidelines

  • Keep helpers focused and composable.
  • Avoid side effects during import.
  • Prefer explicit function/class APIs over implicit globals.
  • Keep dependencies minimal so modules/plugins stay lightweight.

Example Import

from utils.domains.primary_domain import get_primary_domain

What Does Not Belong Here

  • Standalone executable modules (put in library/).
  • Ansible plugin entrypoints (put in plugins/*).
