Keepalive fix, auto-reconnect on disconnect, tab icon fix, video playback guard
Keepalive: tokio::time::sleep inside select! was resetting every iteration — keepalives never fired. Switched to tokio::time::interval which ticks reliably. This caused connections to be zombie-reaped (10min timeout with no pings). Auto-reconnect: unexpected disconnects (stream error, not SocialDisconnectNotice) now attempt direct reconnect after 3s delay using last known address from peers table or social route. Falls back to notify_growth() if direct reconnect fails. Tab icons: updateTabBadge was using textContent which destroyed the icon and label spans inside tab buttons. Now updates only the .tab-label span and manages a separate .tab-badge element. Video playback: feed re-render skipped while any video or audio is actively playing, preventing echo from DOM destruction and media element recreation.

<p style="margin-top: 0.5rem;"><strong>v0.4.3</strong> (2026-03-22): Lock contention overhaul — all conn_mgr lock holds during network I/O eliminated. PostFetch, TcpPunch, PullFromPeer, FetchEngagement, ResolveAddress, AnchorProbe, WormLookup, ContentSearch now use brief locks for data gathering only. Bi-stream handlers (BlobRequest, WormQuery, RelayIntroduce, PostFetchRequest, ManifestRefresh) fully lock-free for I/O. ConnectionActor hoists shared Arcs (storage, blob_store, endpoint) for lock-free access. ResolveAddress adds 5s per-query timeout (was unbounded). Worm cascade uses connection snapshots. Initial exchange failure now aborts mesh upgrade (was silently continuing). connect_to_peer/connect_to_anchor use 15s timeout. StoragePool — 8 concurrent SQLite connections in WAL mode replace single Mutex<Storage>. Reads run fully parallel; writes serialize only at SQLite level. Bottom nav bar for mobile/tablet (≤768px) with icon tabs. Text sizes: XS 75%, S 100%, M 125% (default), L 150%, XL 200%. Text size persisted to localStorage for instant restore. Fix: blocking_lock panic inside async runtime (prevented app startup). StoragePool reduced to 4 connections for Android compatibility.</p>

Keepalive fix — tokio::time::sleep inside select! was resetting every loop iteration, keepalives never fired; switched to tokio::time::interval. Auto-reconnect on unexpected disconnect — 3s delay then direct reconnect to last known address; falls back to growth loop. notify_growth on disconnect — immediately signals growth loop to fill empty slot instead of waiting 10min rebalance. Tab badge fix — updateTabBadge was using textContent which destroyed icon+label spans; now updates only the label and manages badge span separately. Feed re-render skip during media playback — prevents video echo from DOM destruction.</p>

<p><strong>v0.4.2</strong> (2026-03-22): Welcome screen — startup shows “How’s it goin?” with staggered counters (connections, posts, messages, reacts, comments) while backend bootstraps. Status ticker — header ticker for new posts, messages, reactions, comments, connection changes. Notification improvements — Tauri plugin → Web Notification → notify-rust fallback chain, Linux native notifications. Responsive text scaling — Small/Normal/Large (100%/150%/200%), persisted via settings. Diagnostics popover — diagnostics moved from inline section to overlay, connections on-demand, timers removed. Share details lightbox with QR code. Connect string prefers external address (UPnP/public IPv6/observed). Stale N1 fix — disconnected social routes excluded from N1 share. Replication handler fix — actively fetches posts + blobs from requester after accepting replication. Hole punch fix — target-side registers publicly routable remote address for relay introduction. Replication semaphore (3 concurrent max). Peer labels show truncated node ID.</p>
|
||||
<p><strong>v0.4.1</strong> (2026-03-21): Security hardening — reaction signatures (ed25519), comment signature verification on receipt, reaction removal authorization, BlobHeader author verification. Lock contention fixes — ManifestPush discovery (cm lock released during I/O), pull request handler (filter without lock), pull sender (split into brief locks), engagement checker (batch writes per chunk). Data cleanup — post deletion cleans downstream/upstream/seen tables.</p>
|
||||
<p><strong>v0.4.0</strong> (2026-03-21): Protocol v4 — header-driven sync. ManifestPush as primary post notification. Slim PullSyncRequest (per-author timestamps, not full post ID list). Tiered engagement checks (5min/1hr/4hr/24hr by content age). Multi-upstream (3 max) with fallback chain. Auto-prefetch followed authors <90d. Self Last Encounter per-author tracking. Encrypted-but-not-for-us CDN caching. Serial engagement polling. ~90% bandwidth reduction for established nodes.</p>
