Review mirror of GeiserX#266 (CodeRabbit is rate-limited there). Findings are fixed on the real PR; this one is closed after.

Summary by CodeRabbit

  • Bug Fixes
    • Fleet views no longer display outdated redraw results after a newer refresh starts or the view changes.
    • An open proxy editor remains open when the same proxy is redrawn, preserving its editing context.
    • Activity helper cleanup waits for another app’s helper to finish or remain stuck for over 30 seconds. Failed diagnostics now report errors, and snapshots are marked partial if all attempts fail.
    • Money4band imports omit apps that are off or contain only template placeholders.
  • Documentation
    • Updated proxy guidance.
  • Tests
    • Added coverage for Fleet redraws, proxy editor behavior, and comparisons of import mappings.

…xy draft

renderFleet wrote the page after two backend reads without checking that Fleet
was still shown, so a slow read put Fleet over the view the owner had opened.
Every proxy action also redrew the editor from the saved proxy, dropping
unsaved values. A redraw now drops itself when it is stale, and carries the
live editor over when the same proxy's editor is drawn again.

Walkthrough

Fleet redraws now discard stale results and results produced outside the Fleet view. When the editor identity remains the same, redraws preserve the open proxy editor and its DOM-held values.

Changes: Fleet rendering and proxy editor

Layer / File(s) Summary
Fleet redraw ownership and editor preservation
frontend/src/render/proxies.ts, frontend/src/main.ts, frontend/scripts/proxies_check.mjs, CHANGELOG.md
Redraw checks require the latest request and the Fleet view. Fleet rendering preserves the live proxy editor when its ID matches the newly rendered editor. Script checks cover redraw freshness, editor identity, and draft preservation or discard. The changelog records these notes alongside other listed fixes and updates.

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

Change: Bug fix

Merge Risk: Low · up to 7014b

Redraw and draft-preservation regressions could escape the current checks. Renderer-level coverage is recommended as follow-up.

Architecture risk: Low · up to 7014b

Review details

Systems and components

  • observed — frontend (service) was modified; 3 changed files map to changed impact.
  • observed — CHANGELOG.md (service) was modified; 1 changed file maps to changed impact.

Before / after behavior

  • observed — Modified behavior in CHANGELOG.md: Added Unreleased Fixed notes covering Fleet redraw and proxy-editor behavior, Activity helper and dump handling, money4band placeholder imports, proxy guidance, and import-mapping comparison in make catalog-check.
  • observed — Modified behavior in frontend/scripts/proxies_check.mjs: The script adds a comment describing redraw and draft-preservation checks and imports fleetRedrawIsCurrent and keepsLiveProxyEditor from the proxy renderer module.
  • observed — Modified behavior in frontend/scripts/proxies_check.mjs: Adds checks that a redraw is current only when Fleet remains the active view and its version is newest. It also checks that edit and add forms have distinct editor IDs, redraws preserve drafts for the same editor, switching editors discards the previous draft, and a closed editor restores no draft.
  • observed — Modified behavior in frontend/src/render/proxies.ts: Added fleetRedrawIsCurrent, which returns true only when the redraw request equals the latest request and the active view is "fleet".

Explanation

Docstring coverage is 66.67% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 3 functions across 3 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

- Line 1392: Older redraw requests can overwrite shared proxy state before the
freshness check; keep the result of GetProxiesState local until
fleetRedrawIsCurrent confirms the request is current, then assign it to
proxiesState before wireProxies uses it. Preserve the existing stale-request
early return.

114-129: Trivial · Maintainability & Code Quality · Heavy lift

Add a renderer-level redraw test.

The checks test helper results, not renderFleet or DOM restoration. A regression that removes the freshness guard or editor replacement can pass them. Test delayed Fleet responses across navigation and overlapping redraws, and assert that a matching editor retains its typed values.

Add renderer-level coverage in the redraw checks that exercises renderFleet and
actual DOM restoration, rather than only calling fleetRedrawIsCurrent and
keepsLiveProxyEditor. Simulate delayed Fleet responses after navigation and
overlapping redraws, and verify stale responses are dropped while a matching
open editor retains its typed values.
