kevinveenbirkenbachandClaude Opus 5 e16d807e62 fix(cache): refuse a tor deploy whose node onion is empty
get_merged_domains gated the onion injection on node_onion being set AND
svc-net-tor being in group_names. When the node was empty it answered the
clearnet map with no error and no log line, and because group_names is
part of the cache key, a clearnet map and an onion map coexist in one
process under separate keys. One render then serves onion while another
freezes a clearnet asset URL into a stylesheet.

That URL is unrecoverable at request time: body_filter.lua returns a CSS
response before onionize(), so the <link href> in the head is rewritten
while the url(...) inside the stylesheet body is not. The symptom is a
single toHaveCSS mismatch and nothing else.

An empty node under a deployed svc-net-tor now raises. A scope carrying no
group_names at all stays silent, because that is indistinguishable from a
legitimate non-tor deploy.

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/*).
