v3.2.2 — render crash fix, architecture cleanup

on GitHub

[3.2.2] — 2026-03-29

Fixed

• Render crash on page load — displayBlocks was referenced before its const declaration in renderBlocks(), causing an uncaught ReferenceError in the popup. Sort and stats code now correctly follow the displayBlocks construction

Changed

• Block display logic extracted to computeDisplayBlocks() — pure function with no DOM or global dependencies; fully covered by unit tests
• Pi-hole blocklist lookups now parallel — fetchBlocklistReasons uses Promise.allSettled() instead of sequential await per domain; significant speedup on popups with many blocked domains
• Block objects never mutated during render — display classifications are computed as an immutable derived view; fixes subtle re-render inconsistencies on double renderBlocks() calls
• blocklistCache only cleared on new data — filter toggles no longer trigger redundant API re-fetches to NextDNS/Pi-hole
• _activeDB seeded from bundled JSON before async initDB() — eliminates the cold-start window where all domains classified as "Unknown"
• DB empty state now visible — settings panel shows ⚠ DB failed to load warning instead of silently classifying everything as unknown
• blocks Map capped at 100 entries per tab — prevents unbounded memory growth on long-lived tracker-heavy pages
• DB version only bumps when content changes — SHA-256 hash of compiled entries prevents spurious cache invalidation on code-only rebuilds
