When a user joins a voice channel while already connected from another
tab, the server now sends a 'displaced' reason on voice_disconnected.
The client tears down LiveKit and shows an informational toast.
profileSync stored avatar/banner paths with /api/uploads/ prefix on remote
instances, causing resolveAssetUrl to produce double-path URLs like
https://remote/api/uploads//api/uploads/file.jpg that 404'd. Store bare
filenames instead, strip prefix defensively in resolveAssetUrl and server-side
for existing data self-healing.
Root cause: own messages echoed by the server marked channels unread when
the user had already navigated away. Seven related bugs compounded the
problem — stale read states, missing cleanup on space/DM removal, REST
broadcast ignoring VIEW_CHANNEL, and no validation on channel_ack writes.
Frontend:
- Skip markChannelUnread for the user's own messages (federation-aware)
- Walk backward past temp_ IDs in ackChannel instead of bailing
- Re-fire ack timer when temp message is replaced by server-confirmed ID
- Add removeChannelStates to clean up unread/read/message caches
- Clean up chatStore on removeSpace, removeDmChannel, removeInstanceSpaces
Server:
- Use sendToChannel instead of sendToSpace for REST message creation
- Clean up read_states on space deletion, member kick/leave, and ban
- Validate channel membership before accepting channel_ack writes
- Clean up read_states on DM leave and DM channel deletion
- Resize avatars/icons to 256px and banners to 1280px (client crop + server safety net)
- Add server-side resizeProfileImage() for federation/API uploads without crop modal
- Fix unconstrained crop on RegisterPage and CreateSpace (was missing maxOutputDimension)
- PWA: switch to autoUpdate with skipWaiting/clientsClaim for seamless deploys
- Storage janitor: exclude profile images from unlinked cleanup, delete stale thumbnails
- Add deleteAttachmentByFilename() to clean orphaned attachment records for profile images
- Migration: one-time cleanup of stale profile image attachment records
- GeneralPanel: wrap in <form> to prevent implicit submission
isValidAssetUrl() was rejecting bare filenames (e.g. "1234567890.webp") which
is the established convention the frontend sends. Now accepts bare filenames
while still blocking path traversal and unsafe schemes.
Also updates client-side password validation to match server's 8-char minimum.
- SSRF protection: DNS resolution + private IP blocking on metadata fetcher
- Upload security: CSP/X-Frame-Options headers, SVG forced download, nosniff
- Auth hardening: JWT secret min length, password min 8 chars, token revocation via password_changed_at
- Attachment ownership verification before linking to messages
- Message length limit (4000 chars) enforced on client and server
- Asset URL validation on avatar/banner updates
- Federation instance validation (domain regex, origin scheme, length limits)
- DB indexes on all FK columns for query performance
- Migrations: nullable moderator columns, dm_messages reply_to FK constraint
- File cleanup on avatar/banner replacement and space deletion
- Fastify trustProxy, AbortController on fetches, typing map size cap
- Add extension-based mimetype fallback in uploads route so thumbnail
files serve correct Content-Type (image/webp) instead of falling back
to application/octet-stream when DB lookup misses
- Skip animated images (metadata.pages > 1) during thumbnail generation
to preserve GIF/WebP animations instead of flattening to static frame
- Remove redundant explicit thumbnail deletion in storageJanitor since
deleteUploadFile() already auto-deletes the thumbnail variant
- Add "Discover People" section to Add Friend tab with user cards, mutual counts, and inline actions
- Add discoverStore for fetching/searching discoverable users across local and federated instances
- Add PrivacyPanel to user settings with discoverability toggle
- Add is_discoverable column to users table with migration
- Fix "Send Friend Request" button vertical alignment using transform centering
Cancelled requests now disappear from receiver's UI instantly, and
declined requests revert the sender's discover card from "Request
Pending" to "Send Friend Request" — no page refresh needed.
Also includes the discover endpoint and sendFriendRequest return type
changes from the prior session.
One-time async migration runs after server is listening — generates 800px
WebP thumbnails for all existing image attachments that lack one. Gated by
a persistent flag in instance_settings so it never re-runs.
Avatars/banners now resize to max 512px/1920px and convert to WebP before
upload (zero server cost). Chat image uploads generate an 800px-wide WebP
thumbnail via Sharp; the feed shows the thumbnail, click opens the full-res
original. Adds lazy loading to avatars. Federation-compatible: remote
instances without this feature fall back gracefully.
- Add spaceId to InvitePreview so the client can navigate to the space
- Detect "already a member" error and show green success card with auto-redirect
- Add "I use another instance" link for authenticated users alongside "Not you? Log in"
Make /join/:code a public route with a standalone JoinPage that shows a
space preview and handles authenticated, unauthenticated, and cross-instance
users. Adds GET /api/spaces/invite/:code/preview (no auth) endpoint,
?redirect= param support on login/register, and cleans up dead invite
handling from AppLayout and JoinSpace modal.
- Rewrite ChannelSettingsModal with full tri-state permission override UI
for roles and members (allow/neutral/deny per permission bit)
- Switch font from Inter to self-hosted DM Sans (woff2 variable fonts)
- Add client-side VIEW_CHANNEL filtering in ChannelSidebar for private channels
- Broadcast isPrivate flag on channel override changes
- Fix voice permission bit migration: gate behind persistent flag to prevent
repeated re-runs that stripped STREAM from @everyone roles
- Add speakingUserIds set to voice store for efficient user-level lookups
- Clear current channel view when a channel is deleted
- Move .glass-strip to @layer utilities for proper CSS specificity
- Simplify avatar initials font size to proportional formula
Profile and space layout changes on remote instances were being
overwritten by stale data on reconnect. Adds Last-Writer-Wins
timestamps so the client-relay mesh rejects stale writes:
- profile_updated_at column on users table with migration + backfill
- Server LWW guards on PATCH /users/@me and PUT /space-layout
- Bidirectional profileSync: pulls newer remote profiles to home
- LWW layout sync replaces home-authoritative _layoutFromTrueHome flag
- Layout pushes to ALL connected instances in parallel
Remove FK constraint on space_folder_members.space_id so federated
space IDs (which don't exist in the local spaces table) can be added
to folders without silently failing. Add migration to recreate the
table for existing databases and explicit cleanup on space deletion.
Offset drop indicator lines by 3px into the mb-1.5 gap so adjacent
items share one visual position instead of showing two lines.
Extract TransferOwnershipModal (~165 lines) to its own file.
Add user_space_layout table and PUT /api/users/@me/space-layout endpoint
for persisting per-user sidebar ordering. Spaces can be freely reordered
via drag-and-drop, folders created by dragging one space onto another,
and folders auto-dissolve when they have fewer than 2 members. Includes
folder context menu (rename, color, ungroup), collapsed folder mini-grid
icons, multi-tab sync via WebSocket, and localStorage collapse state.
Removes the rigid native/federated split — federated spaces now intermix
freely while keeping their globe badge.
Add Delete Channel button to channel settings modal with ConfirmDialog
confirmation. Fix backend DELETE route to disconnect voice users, clean
up attachment files from disk, and remove orphaned read_states. Make
deleteChannel federation-aware in spaceStore and clean up voiceUsers
on channel_deleted WebSocket event.
Add CreateCategory modal (replaces browser prompt) and right-click
"Delete Category" context menu on category headers with confirmation
dialog explaining channels will be uncategorized, not deleted.
Voice channels already support video/screen share, so the separate video
type was redundant. Adds migration to convert existing video channels.
Also adds border-border-soft to CreateChannel input fields for visibility.
Add avatarColor field to spaces, matching the user avatar color system.
Spaces get a random color on creation and owners can change it in space
settings. The color controls the fallback gradient when no icon is uploaded,
replacing the old deterministic hash-based gradient. Includes full
federation support, explore page, mutual spaces, and color picker in both
create and settings modals.
Enforce lowercase usernames at registration/login, migrate existing
usernames, and fix ownership checks for federated spaces by resolving
user identity per-instance with getMyUserIdForOrigin.
- Add fileCleanup utility to delete uploaded files from disk on message/account deletion
- Add migration to clean orphaned DM channels, attachments, reactions, read states, and stale moderator refs
- Add FK constraints on dm_message_id in attachments and dm_reactions schema
- Make bans.bannedBy and voiceRestrictions.moderatorId nullable for deleted moderators
- Transfer group DM ownership on member leave or account deletion
- Fully clean up orphaned DM channels (zero members) including files
- Add "Leave Group" context menu for group DMs in ChannelSidebar
- Add leaveDm action to spaceStore
- Add account deletion with tombstone (isDeleted flag), password/username
confirmation, owned-space guard, and full cleanup transaction
- Free deleted usernames by renaming to !deleted:<id> so they can be reused
- Add migration to retroactively free usernames from already-tombstoned users
- Add GET /api/auth/check-username endpoint with rate limiting for real-time
availability checking during registration
- Add debounced username availability indicator on registration Step 1
- Add DeleteAccountModal with federation-aware remote account cleanup
- Add federation ops utility for remote instance management
- Update sanitizeUser to anonymize deleted user profiles
- Add instance store improvements and connected instances modal updates
Refactor RegisterPage into a two-step flow: credentials first, then
personalization (display name, avatar upload, avatar color). Replace the
dual-panel sliding layout with conditional rendering and CSS keyframe
animations to eliminate overflow-hidden clipping of focus rings.
Supporting changes:
- Server accepts avatarColor on registration
- Auth store resets all user-scoped stores on login/register/logout
- Voice store gains resetSession() for full session cleanup
- Sync presence status to federated instances
- Propagate presence_update to socialStore regardless of origin
Broadcast user_updated events over WebSocket when profile fields change,
updating members, DM participants, friends, and cached messages in real time.
Widen useVoiceParticipantMeta to return the full user object and add a
standalone avatarColor prop to Avatar so all ~16 callsites now resolve
the user's chosen gradient color instead of falling back to hash-based colors.
Remove placeholder buttons (Threads, Inbox, Help) from channel and DM
headers. Add full-text message search with backend endpoints for both
space channels and DMs, supporting filters (from, has, before, after)
and pagination. Search popover with debounced input, highlighted matches,
and jump-to-message that scrolls with a highlight animation. Includes
messages/around endpoints for loading context when jumping to uncached
messages.
Add server-side heartbeat using RFC 6455 protocol-level ping/pong frames
to detect abruptly disconnected clients (e.g. PC shutdown without TCP FIN).
Dead connections are terminated within ~65s, triggering the existing
cleanup chain to remove ghost users from voice channels and presence.
Add avatarColor as a stored, user-selectable field (mint, sky, lavender,
coral, rose, teal, amber). Randomly assigned on registration, changeable
in profile settings. Existing users keep hash-based fallback until they
choose a color. Includes DB migration, API validation, gradient map,
live preview in settings, and banner fallback integration.
Space avatars in the mutual spaces tab now use getSpaceGradient() instead of
a flat grey background, matching the sidebar appearance. Mutual friends and
spaces from remote instances show a globe icon with the instance hostname.
Also wires up federated mutuals loading, correct API client routing for
remote user profiles, and the new mutuals utility.
Add banner image, accent color, and bio fields to user profiles with
full-stack support: schema migration, API validation (hex color format,
190-char bio limit), sanitizeUser propagation, and new GET /users/:id/mutuals
endpoint. Rewrite AccountPanel with live preview card, avatar/banner upload
via ImageCropModal, 16-preset accent color picker, and bio editor. Enhance
UserProfilePopout with banner display, accent-colored names, bio rendering,
and mutual counts. Add new UserProfileModal with About/Mutual Friends/Mutual
Spaces tabs and friend action buttons.
Remove the unused USE_VOICE_ACTIVITY permission bit (was bit 25) and shift
STREAM to bit 25, DISCONNECT_MEMBERS to bit 26. Add a database migration to
remap stored permission values. Gate camera and screen share buttons in
VoiceControlBar behind canSpeak/canStream, matching VoiceControls behavior.
Permission changes now take effect immediately without requiring
disconnect/reconnect. Modeled as "permission mute" parallel to
server mute — server recomputes SPEAK for all voice participants
on role/override changes and broadcasts state via WebSocket.
Includes amber UI indicators and mic toggle blocking.
- Add DISCONNECT_MEMBERS permission (bit 27) to disconnect users from voice
- Implement voice_disconnect WebSocket handler with permission checks
- Add disconnect button to voice user context menu
- Grant instance admins full permissions across all spaces
- Fix voice_disconnected handler to use federation-aware identity resolution
- Update CLAUDE.md with new event types and permission docs
- Add migration to convert legacy JSON array permissions to decimal strings
- Add runtime fallback in stringToPermissions for legacy format
- Show all permission toggles as enabled (dimmed) when Administrator is on
- Replaces global `userId` tracking with `spaceId:userId` composite keys across both backend and frontend, fixing the issue where server-muting a user in one space bled into others.
- Modifies client-side `ready` event hydration to merge voice states per-origin instead of completely overwriting the store, preventing federated connections from wiping out home instance mutes.
- Excludes server voice restrictions from `zustand/persist` so stale client caches don't override the server's authority on reload.
- Fixes React component reactivity by using reactive store selections for `spaceId` instead of imperative `getState()` calls, ensuring UI lockdown indicators accurately reflect the initial websocket handshake.
- Client ready handler now builds restriction Sets atomically in a single
setState call, eliminating intermediate empty-Set state that caused amber
icons to flash rose on reload
- buildReadyPayload queries all voice restrictions from DB across the
user's spaces instead of relying on in-memory state (which is lost on
disconnect timeout)
- voice_join early-return path now re-broadcasts restrictions to the
reconnecting user, covering fast reload where the user is still in the room
Server-side: add DB persistence for voice restrictions (schema, migration,
ready payload, cleanup on leave). Client-side: fix four bugs that wiped or
bypassed server restriction state — leaveVoice() no longer clears global
restriction Sets, voice_state_update leave no longer drops amber icons,
toggleMic/toggleDeafen now guard against server restrictions, and force-mute/
deafen uses direct setState instead of fragile toggle calls.
