SQLite stores self-referencing FK identifiers with quotes (REFERENCES
"dm_messages"), but the migration guard only checked for the unquoted
string. This caused the migration to re-run on every server startup,
which DROP TABLE dm_messages and triggered ON DELETE CASCADE on
attachments.dm_message_id — wiping every DM-linked attachment.
When a relay-created dm_message_created arrives for an unknown channel,
check if an existing DM has the same member (by homeUserId). If so,
route the message to the existing channel instead of adding a duplicate
sidebar entry. Prevents the transient duplicate that required page
refresh to dedup.
Reaction outbox events used reactionId (add) or a composite dedup key
(remove) as the event messageId. The receiver looked up dm_messages by
sourceMessageId = event.messageId, which never matched because it was
searching for a reactionId, not the actual message ID.
Fix: include the actual DM messageId in the reaction payload JSON.
The receiver now uses event.reaction.messageId for the lookup, with
fallback to event.messageId for backward compatibility.
After the file worker downloads a federated attachment, generate a
thumbnail using the same sharp pipeline as local uploads. This ensures
federated images use bandwidth-efficient thumbnails in chat view
instead of serving the full-size image.
Also fixes processCreateEvent to not copy the source instance's
thumbnailFilename (which doesn't exist locally).
The source instance's thumbnail file doesn't exist locally, so copying
its thumbnailFilename causes a 404 in the chat view. Set to null so
AttachmentRenderer falls back to the full image URL.
The file worker now UPDATEs the attachment row created by processCreateEvent
(swapping sourceUrl interim filename to local path) instead of INSERTing a
duplicate. Falls back to INSERT for legacy queue entries.
After download, broadcasts dm_message_updated so clients see the attachment
transition from remote hotlink to local file in real-time.
Insert attachment rows with sourceUrl as interim filename so the initial
WebSocket broadcast includes working remote URLs. AttachmentRenderer
already handles http:// filenames as direct URLs. The file worker will
UPDATE the filename to the local path after download completes.
This fixes the invisible bubble bug where attachment-only messages
(content: null, attachments: []) appeared as empty messages.
Single function builds complete relay payload with attachments (including
sourceUrl) and participants. Eliminates 4-way duplication that caused
the attachments: [] hardcode bug.
The relay was failing because processCreateEvent relied on the friends
table to discover the DM recipient, but friendships aren't federated
across instances. Also, resolveLocalUser matched deleted replicated
users before active ones.
- Add participants[] to FederationRelayEvent with homeUserId/homeInstance
for all DM channel members
- Add getDmParticipants() helper to look up member identities
- Include participants in outbox payloads (create/update) and sync events
- Rewrite processCreateEvent to resolve participants directly, compute
canonicalDmPairId, and findOrCreateDmChannel — removing the entire
friends-list fallback (60+ lines)
- Fix resolveLocalUser to filter out deleted users (is_deleted = 0)
and prefer the replicated user match when multiple candidates exist
The old query missed channels where both members appear as 'local'
(e.g., native Nova + native youruser on orbit). Using
canonical_pair_id is simpler and correct — any channel with a pair
ID is a federated DM that should be synced.
Messages by replicated users (e.g., Jannis browsing orbit) have
source_instance IS NULL because they were created on that instance.
The sync endpoint was incorrectly filtering these out, causing most
DM history to be missing from the sync response.
- buildRelayPayload now uses config.domain for local users instead of
empty string, so the relay receiver can resolve the user
- Fixed canonical_pair_id backfill: SQLite NULL || ':' || x = NULL,
so use COALESCE(home_user_id, id) instead of concatenation
Existing 1-on-1 DM channels created before federation had canonical_pair_id = NULL,
causing the relay to create duplicate channels on receipt of a message. On server
startup, migrations now: (1) compute and set canonical_pair_id for all existing
1-on-1 channels using home_user_id (falling back to regular id for local users),
and (2) merge any duplicate channels that share the same canonical_pair_id by
moving all messages, read states, and members into the oldest channel and deleting
the stale duplicate. Both steps are non-fatal and idempotent.
Federation relay was incorrectly defaulting to disabled, requiring
admins to discover a buried settings toggle. Since federation itself
is opt-in (you connect instances manually), relay should be on by
default. Also migrates existing instances from 0 → 1.
Adds a post-deploy step that removes Docker images and build cache
older than 24 hours. Prevents the gradual disk bloat from repeated
docker compose --build invocations (was 71GB on the Pi).
Task 13: Hook server-to-server peering into connectToRemote (non-fatal)
and add federation API namespace to the client (initiate, peers, revoke).
Task 14: Show a transparency notice in the DM welcome header when the
other user is on a remote instance, informing that messages are stored
on both home instances and are not end-to-end encrypted.
Task 15: Add Federation section to the instance settings General panel
with DM relay toggle, TTL config, and a live peer list with revoke
buttons. Also extends InstanceAdminSettings type and the server settings
route to support federationRelayEnabled / federationRelayTtlDays.
Add POST /api/federation/sync for peer instances to catch up on missed
DM mutations after downtime. Uses HMAC-SHA256 authentication (same as
relay), determines shared channels between peers via raw SQL join on
dm_members/users, queries the federation_mutation_log with timestamp
pagination, and returns FederationRelayEvent payloads for each mutation
type (create, update, delete, reaction_add, reaction_remove).
Add federation routes module with four endpoints:
- POST /api/federation/peer/initiate — admin-only, starts peering handshake
with a remote instance (validates origin, generates HMAC secret, sends
server-to-server accept request with 10s timeout)
- POST /api/federation/peer/accept — server-to-server first contact,
rate-limited to 10 req/min per IP, creates/activates peer record
- GET /api/federation/peers — admin-only, lists all peers (hmacSecret excluded)
- DELETE /api/federation/peers/:id — admin-only, revokes peer and cleans outbox
Adds column migrations (dm_channels.canonical_pair_id, dm_messages.source_*,
attachments.source_url, instance_settings.federation_relay_*), CREATE TABLE
for federation_peers/outbox/file_queue/mutation_log, partial/filtered indexes,
and an idempotent backfill that seeds the mutation log from existing DM messages.
Also makes migrateDmMessagesReplyToFk and migrateAttachmentsDmMessageFk
column-aware so table recreation preserves any columns added by earlier
migrations (prevents dropping federation columns on upgrade).
The dist < 150 check caused the ResizeObserver and media load
listener to miss large layout shifts (e.g., GIF loading adding
400+ px of height). The isAtBottomRef gate already determines
whether to auto-scroll — the pixel threshold is redundant.
Remove isAtBottom state from scroll effect deps to break the
re-triggering feedback loop. Use isAtBottomRef (ref) instead.
Gate ResizeObserver and media load effects behind the ref so
they only auto-scroll after the initial snap completes.
Images now size naturally within max constraints instead of being
letterboxed into a 4/3 bg-surface-input container. Fixes dark bars
on GIFs and images whose aspect ratio doesn't match 4/3.
PNG conversion strips GIF animation. GIFs are now detected by URL
pattern (.gif extension or Tenor/Klipy CDN) and copied as URL text
instead, so pasting back into chat re-renders the animated GIF.
Add data-embed-thumbnail marker to VideoEmbed, GenericEmbed, and
RichEmbed thumbnail containers. Update detection logic to skip
these alongside avatars. Also remove redundant filename derivation
in Save Image menu item.
Detect right-clicked images in handleContextMenu and prepend
Save Image, Copy Image, and Open Original to the custom menu.
Avatars are excluded via the data-avatar semantic marker.
Implements image save/download (blob fetch + anchor trigger, fallback to window.open)
and clipboard copy (PNG write via ClipboardItem, fallback to URL text copy) with
toast feedback. Also adds ClipboardItem polyfill and Response.blob() content-type
fix to the jsdom test setup so the clipboard test suite runs correctly.
Refactor useGridLayout from RefObject to callback-ref API so the
ResizeObserver reattaches when the grid container remounts after
focus-mode toggle. Fixes tiles rendering at stale fullscreen dimensions
on 4:3 monitors.
Also clamp focus-mode participant strip height (max-h-[20vh] min-h-[80px])
to prevent it from crowding the focused stream on short viewports.
Lower minimum query length from 2 to 1 character so single-letter
searches return results.
Fix dedup to prefer native profiles (homeUserId=null) over replicated
ones. Previously the first-seen result won, which was usually the
local replicated profile (no instance badge, namespaced username).
Now when a native profile is found on the remote instance, it replaces
the replicated copy — showing the clean username with the instance badge.
Replicated profiles on remote instances have different local IDs but
share the same homeUserId as the native profile. Use homeUserId ?? id
as the dedup key so the same person only appears once. Home instance
is queried first, so the native profile (with clean username) wins.
Replace old "Add Friend" form tests (placeholder/button/inline messages) with
new tests for the Find People panel: search input, Direct Add row, toast feedback,
and searchUsers debounce. Also fix ancillary mocks (discoverStore, authStore,
activityStore, ConnectInstanceModal, findExistingDmForUser) required by the
rewritten component.
Replace the two separate inputs (direct add + discover search) with a
single unified search field. When the user types, results come from
socialStore.searchUsers() across all connected instances. When empty,
the discover grid is shown as before. A user@instance pattern surfaces
a Direct Add action row for sending friend requests to federated users.
Parent FriendsPage no longer owns add-friend state — it all lives inside
AddFriendTab now, keeping the component self-contained.
When a WS connection receives its ready event, push cached myActivities
to that instance so federated users see activities immediately without
waiting for the next debounce cycle.
Switch pushActivities and setShowActivity from wsSend (home-only) to
wsSendAll (all instances). Add myActivities cache for re-push on late
connections.
Inserts a new tier 3 between DM member lookup and identity-only fallback.
When the current space's member list doesn't contain the voice participant
(user navigated to a different space/instance), the hook now falls back
to the cached User object from ParticipantInfo. This preserves avatar,
avatarColor, displayName, and homeUserId for federated users in PiP.
The isLocal branch was falling through to cachedUser.id when
homeUserId was null, diverging from the null-for-home-instance
contract used by the memberMatch and carry-forward branches.
Avatar.tsx already falls back to user.id internally.
Extends ParticipantInfo with cachedUser: User | null. In updateParticipants,
snapshots the previous participant list and carries forward the cached User
object when spaceStore member lookup fails (user navigated to a different
space). Local user falls back to authStore. homeUserId is now derived from
cachedUser when the direct member lookup misses. Updates EMPTY_PARTICIPANT
in PictureInPicture.tsx.
InstanceNotConnectedError and InstanceDisconnectedError now open the
ConnectInstanceModal instead of being swallowed silently. After the user
connects/reconnects, the friend request is retried automatically and a
success toast confirms both the connection and the sent request. All
other friend action errors (remove, cancel, accept, decline) now surface
as warning toasts instead of being silently discarded.
stopScreenShare() resets hwOverdrive: false, which clobbers the
user's intent when switching VP9 → H.264 HW mid-stream. Save
and restore the flag around the restart.
