Siavash Sameni	ba12aae439	refactor: extract shared engine helpers, federation clone-before-send, constants ... Engine deduplication (PRD-engine-dedup.md): - build_call_config(): shared CallConfig construction (was 23 lines × 2) - codec_to_profile(): shared CodecId → QualityProfile mapping (was 19 lines × 2) - run_signal_task(): shared signal handler (was 48 lines × 2) - Net -39 lines from engine.rs, 6 duplicated blocks → single-line calls Quick wins from REFACTOR-codebase-audit.md: - 6 magic number constants extracted (CAPTURE_POLL_MS, RECV_TIMEOUT_MS, etc.) - DRED_POLL_INTERVAL moved from 2 local defs to 1 module-level const - federation.rs: forward_to_peers, broadcast_signal, send_signal_to_peer now clone peer list and release lock before sending (was holding Mutex across async I/O — last lock-during-send pattern eliminated) - main.rs: close_transport() helper replaces 12 silent .ok() calls with debug-level logging 314 tests passing, 0 regressions.

Siavash Sameni	3a51db998a	docs: relay concurrency refactor guide + PRD update for DashMap ... REFACTOR-relay-concurrency.md: complete post-DashMap analysis with current lock inventory, 4 prioritized suggestions (clone-before-send, peer_links DashMap, quality atomics, arc-swap snapshots), decision matrix, and concurrency diagram. PRD-relay-concurrency.md: updated to recommend DashMap as primary approach (was Option A per-room locks).

Siavash Sameni	a52b011fb5	feat(relay): replace global Mutex<RoomManager> with DashMap sharding ... Eliminates the single-lock bottleneck for media forwarding. Before: all participants across all rooms competed for one Mutex. Now rooms are stored in DashMap (64 internal shards with per-shard RwLocks). Changes: - RoomManager.rooms: HashMap → DashMap<String, Room> - Per-room quality tracking (qualities, current_tier moved into Room) - Arc<Mutex<RoomManager>> → Arc<RoomManager> everywhere - 20 .lock().await sites removed across room.rs, main.rs, federation.rs, ws.rs - federation forward_to_peers: clone peer list, release lock, then send - ACL uses std::sync::Mutex (rarely accessed, non-async) Concurrency improvement: - Before: 100 rooms × 10 people = 1000 tasks → 1 Mutex - After: distributed across 64 DashMap shards, ~15 tasks per shard avg - Rooms are fully independent — room A never blocks room B 314 tests passing, 0 regressions.

Siavash Sameni	2514151a89	docs: PRD for relay concurrency — per-room lock sharding ... Full analysis of relay lock contention with precise inventory of every lock acquisition in the hot path. Evaluates 4 design options: A) Per-room Arc<Mutex<Room>> (recommended — 100x improvement for multi-room) B) DashMap (good but less explicit) C) Channel-based fan-out (over-engineered for current scale) D) Snapshot-on-change via arc-swap (best perf, more complex) Phase 1: per-room locks, Phase 2: federation lock fix, Phase 3: quality tracking out of critical path. Estimated 1.5-2.5 days total. Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>	2026-04-13 12:01:21 +04:00
