Summary by CodeRabbit

  • Bug Fixes

    • Linkwarden installations now generate a unique authentication secret instead of using a default value.
    • Removed an unsupported database configuration that could cause issues in single-container installations.
  • Documentation

    • Added changelog entries describing the Linkwarden configuration correction and improved reliability of merge-attribution checks.
  • Tests

    • Added validation to prevent insecure default secrets from being included in service installations.

…ret_key placeholder, remove DATABASE_URL without Postgres companion S2-21

Docs-Reviewed: catalog manifest changed, no README update needed since Linkwarden env removal is a known limitation documented in the manifest itself

📝 Walkthrough

Walkthrough

The Linkwarden manifest now uses generated secrets and no longer declares a local database URL. Installer tests audit service manifests for unsafe secret values. A changelog entry documents a merge-attribution assertion fix.

Changes

Linkwarden secret validation

Layer / File(s) Summary
Manifest secret configuration and audit
app-catalog/services/linkwarden/manifest.yaml, tests/test_installers.py, changelog.d/tsk-saz74u-linkwarden-manifest-static-secret.md
The manifest uses {secret_key} for NEXTAUTH_SECRET and removes DATABASE_URL. Installer tests reject static changeme values and missing secret placeholders. The changelog records the manifest change.

Merge attribution changelog

Layer / File(s) Summary
Merge attribution flake documentation
changelog.d/tsk-oqpbvn-merge-attribution-flake.md
The changelog documents exact #41 matching instead of bare 41 matching in merge-attribution assertions.

Merge Risk: 🔵 Low · up to 0ce08

Linkwarden now receives an installation-specific secret and no longer declares a local database URL, but the new validation can be skipped by an unexpected working directory and the changelog may describe an unapplied test fix. Address these bounded issues before relying on the added audit and release note.

### Tests

- Fixed a CI flake in `tests/test_merge_attribution.py`: two assertions checked that an excluded PR number ("41") was a bare substring of `result.stdout`, but the fixture commit shas are generated at runtime, so a sha for the in-scope PR could coincidentally contain "41" and fail the assertion for a reason unrelated to the actual reconciliation logic. Both now assert on the exact `"#41"` PR-reference token the checker prints, which cannot collide with a hex sha substring.

Align the changelog with the test implementation.

The entry says both assertions now match the exact "#41" token. The supplied tests/test_merge_attribution.py snippet still contains assert "41" not in result.stdout. Update that assertion to "#41" or revise this changelog entry to describe the actual change.

Prevent a vacuous pass when no manifests are discovered.

Path("app-catalog") is relative to the current working directory. If discovery returns no manifests, the loop is skipped and has_issue remains False. Resolve the path from __file__ and assert that at least one manifest was found.

Proposed fix
-    services_dir = Path("app-catalog") / "services"
+    services_dir = Path(__file__).resolve().parents[1] / "app-catalog" / "services"
     manifests = sorted(services_dir.rglob("manifest.yaml"))
+    assert manifests, f"No service manifests found under {services_dir}"

Closing — the fix is inert. {secret_key} is only substituted in config_files content (docker_installer.py:80-88); install.env is copied verbatim into the compose environment block (:127-128) and the compose is written at :175 with no substitution. So every Linkwarden install still ships one static, publicly-known NEXTAUTH_SECRET — now the literal string {secret_key} instead of changeme. The manifest audit test passes precisely because the placeholder text is present, which is the wrong thing to measure; the card's acceptance line ("renders with a distinct secret per install in the installer test") was the test that would have caught this and is missing.

Also: changelog.d/tsk-oqpbvn-merge-attribution-flake.md belongs to #2811 (already on dev), and the audit test resolves app-catalog/services from the cwd and passes vacuously when it finds no manifests (the CodeRabbit thread is right).

Re-carded with the mechanism spelled out (substitute {secret_key} in env values inside _generate_compose, RED test on the rendered compose asserting a 64-hex secret distinct per app dir and stable across reinstall, audit test anchored on Path(__file__) with a non-empty assertion). Card tsk-saz74u closed with the same note.
