Summary

  • Add a hard Host deps preflight before Cargo check (fast gate) that verifies pkg-config and pkg-config --exists glib-2.0 gtk+-3.0.
  • On failure, print a one-line operator hint to install pkg-config libgtk-3-dev libglib2.0-dev on the aws-chefbar-compat host (no sudo apt in the workflow — NoNewPrivileges).
  • Document the AWS runner host-deps requirement in CONTRIBUTING.md.

Confirmed prior failure (job 97001128088): glib-sys failed because pkg-config was missing — infra, not a Rust source bug.

Test plan

  • PR CI: preflight step runs before cargo check
  • On a healthy runner: step prints host-deps OK
  • On a broken host (missing pkg-config): job fails immediately with the aws-chefbar-compat install hint (no multi-minute rustc 101)
  • Confirm workflow does not attempt sudo apt for these packages

Summary by CodeRabbit

  • Documentation

    • Documented required host packages for the self-hosted CI runner.
    • Added guidance for resolving missing glib-sys dependencies and clarified installation requirements.
  • Chores

    • Added a CI preflight check for required pkg-config, GLib, and GTK modules.
    • CI now reports actionable errors and stops early when host dependencies are unavailable.

Surface aws-chefbar-compat host-package gaps before cargo check so operators
get a clear NoNewPrivileges install hint instead of a glib-sys build failure.

AI Description

• Add a CI preflight to verify pkg-config and GTK/glib modules before cargo check.
• Fail fast with a host-install hint on aws-chefbar-compat runners (NoNewPrivileges).
• Document required self-hosted runner host packages in CONTRIBUTING.md.

High-Level Assessment

The following are alternative approaches to this PR:

1. Bake deps into the runner image/AMI
  • ➕ Eliminates runtime failures entirely (preflight becomes redundant)
  • ➕ Keeps workflows clean and consistent across repos using the runner
  • ➖ Requires infra change/rebuild pipeline for the runner
  • ➖ Still benefits from a preflight if hosts can drift over time
2. Run the fast gate inside a container with deps preinstalled
  • ➕ Decouples CI correctness from host package state
  • ➕ Reproducible environment; can include pkg-config/GTK dev libs in the image
  • ➖ May not be feasible with the current runner/permissions model
  • ➖ Adds container build/pull overhead and more moving parts
3. Make GTK-dependent crates optional for the fast gate
  • ➕ Avoids host GTK dependencies for quick checks
  • ➕ Reduces coupling of core checks to GUI-related system libs
  • ➖ Can miss integration breakage in the default feature set
  • ➖ Requires Rust feature refactoring and ongoing feature-matrix maintenance

Recommendation: Keep the current preflight: it’s the smallest change that directly addresses the observed failure mode and matches the NoNewPrivileges constraint (no in-job apt). If runner images are managed centrally, consider additionally baking these packages into the aws-chefbar-compat base image to reduce drift; the preflight can remain as a guardrail.

Document aws-chefbar-compat host dependency requirements

• Adds documentation for required host packages on the self-hosted GHA runner (pkg-config, libgtk-3-dev, libglib2.0-dev). Explains why the workflow cannot install these packages (NoNewPrivileges) and that they must be installed on the host.

Add host-deps preflight before Cargo check

• Introduces a new CI step that verifies 'pkg-config' is present and that 'glib-2.0' and 'gtk+-3.0' are discoverable via pkg-config. On failure, the job exits early with a clear operator hint, avoiding wasted toolchain warmup on misconfigured self-hosted runners.

📝 Walkthrough

Walkthrough

The CI workflow now checks required GTK and glib host dependencies before Rust checks. CONTRIBUTING.md documents the required packages, the related glib-sys failure, and the host installation restriction.

Changes

CI Host Dependency Preflight

Layer / File(s) Summary
Dependency preflight and contributor guidance
.github/workflows/ci.yml, CONTRIBUTING.md
The workflow validates pkg-config, glib-2.0, and gtk+-3.0 before Rust checks. Contributor documentation lists the required host packages and explains the preflight and installation restriction.

Estimated code review effort: 2 (Simple) | ~10 minutes

Merge Risk: 🔵 Low · up to 26ce6

The preflight will fail earlier with clearer host-dependency checks, but the contributor documentation currently describes the failure cases together and may send operators toward the wrong fix. The PR is mergeable with explicit owner awareness or a minor documentation follow-up.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Separate the two host-dependency failure cases.

Line 43 applies the pkg-config-missing error to all missing packages. The workflow has a separate branch for missing glib-2.0 or gtk+-3.0 modules. Document these cases separately so operators do not search for the wrong cause.

Proposed wording
-Zonder die packages faalt `glib-sys` met “The pkg-config command could not be
-found” na een nutteloze toolchain-warmup.
+Zonder `pkg-config` faalt `glib-sys` met “The pkg-config command could not be
+found”. Als `glib-2.0` of `gtk+-3.0` ontbreekt, meldt de preflight dat vóór
+`cargo check`.
