Federated 1-on-1 DMs showed the raw snowflake ID as the display name
and no avatar when the remote user had no pre-existing local record.
processCreateEvent used resolveLocalUser (find-only) instead of
resolveOrCreateReplicatedUser, and relay events carried no profile data
for participants.
- Add profile snapshot (displayName, avatar, avatarColor) to
FederationRelayParticipant and populate it in getDmParticipants
- Change processCreateEvent to auto-create replicated user stubs and
hydrate them with profile data from the relay event
- Fix hydrateReplicatedUserProfile URL resolution for homeInstance
values without protocol prefix
- Fix WelcomeHeader: return null while DM data is loading (eliminates
"unknown" flash on reload), use displayName for @mention text
Bare filenames stored on replicated user stubs can't be resolved by
the home WS (normalizeUserAssets only runs for remote origins).
Now resolves avatar/banner to absolute URLs pointing to the user's
home instance so they render correctly without page refresh.
Also overwrites stale bare filenames from the prior deploy.
Replicated user stubs created by resolveOrCreateReplicatedUser had
null avatar/displayName, causing blank profiles in the UI until
page refresh. Friend relay events now carry profile snapshots
(displayName, avatar, avatarColor, banner, bio) so the receiving
instance can hydrate stubs with real data.
Make both identity resolution helpers module-level exports so the group DM
endpoint can import and use them when resolving federated user identities
during group DM creation.
In processCreateEvent, branch on event.federatedId: group DM messages now
look up the pre-bootstrapped local channel by federatedId instead of
computing a pair hash from two participants. In queueDmRelay, fetch the
channel's federatedId and ownerId and include federatedId in the outgoing
relay payload for group DMs so receiving instances can route correctly.
Add three new event processors to the relay endpoint for handling
inbound group DM membership changes from peer instances:
- processMemberAddEvent: handles member additions with channel bootstrap
(creates the local channel from group metadata on first contact)
- processMemberRemoveEvent: handles member removals with read state
cleanup and soft-delete GC when no local members remain
- processOwnershipTransferEvent: updates local channel owner tracking
All three are wired into the relay endpoint's event dispatch switch.
Uses messageHomeInstance to determine whether the target message
originated locally (lookup by ID) or was replicated from another
instance (lookup by sourceInstance + sourceMessageId). Supports
N-instance federation and falls back to relay-sender lookup for
backward compatibility with in-flight outbox entries.
When Instance 2 receives a relay from Instance 1, it no longer
broadcasts dm_message_created to members whose home instance is Instance
1. Those users already have the original message via their home WS
connection. This prevents duplicate messages from appearing in the
sender's chat.
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.
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.
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.
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.
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
