sendTypingRelay() mirrors sendCallRelay() — direct POST to peers,
no outbox, no retry. Uses federatedId for cross-instance channel
identification. Wired into handleDmTypingStart() for typing_start
and broadcastDmMessage() for typing_stop.
Three stacked bugs prevented federation relay from working for group DMs:
1. Origin format mismatch: users.home_instance stores bare domains
("nova.ddns.net") but federation_peers.origin stores full URLs
("https://nova.ddns.net"). getGroupDmTargetOrigins() built target
lists from bare domains, so queueOutboxEvent() never matched any
peers — events were never queued into the outbox.
2. Missing federatedId in outbox reconstruction: the outbox worker
rebuilt relay events from stored payloads but never copied the
federatedId field. Receiving instances check this field and rejected
all member_add/remove/ownership_transfer events with
"missing_membership_payload".
3. Duplicate channels from cross-instance broadcasts: dm_channel_created
was sent to ALL members including remote replicas. Users connected to
multiple instances received the event twice (once per instance),
creating duplicate group DMs in their sidebar. Fixed by only
broadcasting to members whose home instance matches the current
server — remote members receive the channel via federation bootstrap
on their home instance.
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
Rename appendMutationLog and queueOutboxEvent params from DM-specific names
(dmMessageId/dmChannelId/messageId) to generic (entityId/contextId) with a new
contextType param defaulting to 'dm'. Update all internal schema column references
to match the renamed outbox/mutation-log schema columns. Add buildFriendContextId
and getFriendEventTargets helper functions for friend event relay routing.
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.
Consolidates 4 inline constructions of the instance origin URL into a
single shared function. Removes the private copy in federationWorker
and two ad-hoc domainOrigin variables in federationOutbox.
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
- 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
