Code Review by Qodo
|
Implement group-level disappearing messages where admins can configure a TTL (in seconds) after which messages are automatically deleted from local storage. This builds on mdk-core's new `disappearing_message_duration_secs` field in the MLS group data extension. Key changes: - Bump mdk-core to 00be148 (adds disappearing message fields, EventTag, KeyPackageEventData struct, create_message tags parameter) - Add `expires_at` column to aggregated_messages (migration 0046) with a partial index for efficient cleanup queries - Compute and store `expires_at` on incoming and outgoing messages when the group has a disappearing message duration configured - Add `DisappearingMessageCleanup` scheduled task (runs every 30s) that deletes expired messages and emits chat list updates - Add public API: `set_disappearing_messages()` (admin-gated) and `get_disappearing_message_duration()` on the Whitenoise struct - Attach NIP-40 expiration tags to outgoing kind:445 wrapper events so relays can auto-discard expired ciphertext - Add 13 tests covering DB round-trips, expiry cleanup, edge cases, and ChatMessage serialization

- Line 1: The migration header comment at the top currently reads "Migration
0044: Add expires_at column to aggregated_messages" but the file is migration
0046; update the header text to "Migration 0046: Add expires_at column to
aggregated_messages" so the human-readable header matches the file name (change
the "0044" token to "0046" in the header comment).
In `@src/whitenoise/database/aggregated_messages.rs`:
- Around line 748-756: The upsert currently overwrites expires_at on conflict
(in the ON CONFLICT(message_id, mls_group_id) DO UPDATE SET ... expires_at =
excluded.expires_at), which breaks the "no retroactive expiry" rule; change the
DO UPDATE SET clause to stop modifying expires_at on conflict (either remove the
expires_at assignment entirely or use a non-overwriting expression such as
expires_at = aggregated_messages.expires_at or
COALESCE(aggregated_messages.expires_at, excluded.expires_at)) so existing TTL
on the stored row is preserved; adjust the SQL in aggregated_messages.rs
accordingly.
In `@src/whitenoise/groups.rs`:
- Around line 784-803: The docstring for set_disappearing_messages claims
Some(0) is rejected but the method currently forwards duration_secs to
NostrGroupDataUpdate and update_group_data without validation; either enforce
the rejection here by checking if duration_secs == Some(0) and return an Err
(use the crate's existing error type) before creating NostrGroupDataUpdate, or
update the doc comment to remove the "Some(0) is rejected" claim and state the
actual behavior (delegated to NostrGroupDataUpdate/update_group_data). Locate
the logic in the set_disappearing_messages function and adjust either the
validation branch or the documentation accordingly.

create_mdk_for_accountis called inside nested loops—once per (message, member) pair. If a batch contains many messages in the same group, the same MDK instance is recreated repeatedly for each member account.Restructuring to iterate by account first (open MDK once, then delete all relevant messages) would reduce the overhead:
account_messages: HashMap<PublicKey, Vec<(GroupId, EventId)>> for (account, messages) in account_messages { let mdk = create_mdk_for_account(account)?; for (group_id, event_id) in messages { mdk.delete_message(&group_id, &event_id); } }This is a minor optimization—acceptable for typical usage but could matter during high-churn periods.

chat_message.expires_at = existing_message.expires_at (apply only when
existing_message.expires_at is Some) instead of overwriting it from
disappearing_duration_secs so relay-echo reprocessing retains the original
stored expiry.

In `@db_migrations/0046_add_expires_at_to_aggregated_messages.sql`:
- Line 1: Update the migration header comment in the file
db_migrations/0046_add_expires_at_to_aggregated_messages.sql so it correctly
reflects migration 0046 (change the text "Migration 0044" to "Migration 0046"),
ensuring the header comment matches the file's migration number and avoids
future trace confusion.
In `@src/whitenoise/database/aggregated_messages.rs`:
- Around line 748-756: The upsert SQL in the ON CONFLICT clause currently
updates expires_at (the line containing "expires_at = excluded.expires_at"),
which allows reprocessing to retroactively change expiration; modify the DO
UPDATE SET to stop mutating existing expiry by either removing the expires_at
assignment entirely from the update list in the ON CONFLICT(message_id,
mls_group_id) DO UPDATE SET block, or replace it with a non-destructive
expression such as "expires_at = COALESCE(aggregated_messages.expires_at,
excluded.expires_at)" so existing expires_at is preserved; update the SQL
fragment in aggregated_messages.rs accordingly.

Nitpick comments:
In `@src/whitenoise/message_streaming/types.rs`:
- Around line 33-36: The docs for MessageUpdate currently claim the payload is
always complete/current but the MessageExpired variant (in the MessageUpdate
enum) is an exception where all fields except id are deleted/invalid; update the
MessageUpdate documentation to explicitly state that when
MessageUpdate::MessageExpired is sent consumers must only trust the id field
(and treat other fields as absent/ignored), and mention MessageExpired by name
so readers can find the exception easily when handling MessageUpdate.
In `@src/whitenoise/scheduled_tasks/tasks/disappearing_message_cleanup.rs`:
- Around line 97-119: The loop currently calls whitenoise.create_mdk_for_account
inside the inner per-member loop leading to repeated MDK construction for the
same account; refactor to group message deletions by account (e.g., build a
mapping from account_pubkey -> Vec<(group_id, event_id, message_id_hex)>), then
iterate accounts once, call create_mdk_for_account(account_pubkey) to obtain a
single MDK, and call mdk.delete_message(group_id, &event_id) for each message;
ensure error handling/logging (tracing::warn) remains when
create_mdk_for_account or delete_message fail and keep referencing the same
symbols (create_mdk_for_account, delete_message, account_pubkey, group_id,
event_id, message_id_hex, whitenoise).

Summary
Adds group-level disappearing messages, closing #278. Admins set a TTL (in seconds) on a group; every message stored after that gets an
expires_attimestamp. A background task sweeps expired rows every 30 seconds and notifies the UI.This marmot learned to build hourglasses into the burrow walls. Messages that overstay their welcome get politely escorted out.
What changed
mdk-core bump (commit
00be148): picks up the newdisappearing_message_duration_secsfield onNostrGroupDataExtensionv3, theEventTagtype for NIP-40 expiration, and theKeyPackageEventDatastruct replacing the old tuple return.Database (
0046_add_expires_at_to_aggregated_messages.sql): adds a nullableexpires_at INTEGERcolumn toaggregated_messageswith a partial index on non-NULL rows so cleanup queries stay fast regardless of how many permanent messages exist.Message lifecycle: both incoming (
cache_chat_message) and outgoing (process_and_emit_outgoing_message) paths now read the group's disappearing duration and computeexpires_at = created_at + duration. Outgoing messages also get a NIP-40expirationtag on the outer kind:445 wrapper so relays can discard stale ciphertext.Scheduled task (
DisappearingMessageCleanup): runs every 30s, deletes rows whereexpires_at <= now, and emitsLastMessageDeletedchat-list updates for affected groups.Public API on
Whitenoise:set_disappearing_messages(account, group_id, duration_secs)(admin-gated viaensure_account_is_group_admin)get_disappearing_message_duration(account, group_id)returnsOption<u64>ChatMessage.expires_at: new field visible to frontends so they can show countdown indicators or "this message will disappear" UI.Design decisions
expires_at(or lack thereof). This matches Signal/WhatsApp behavior.Summary by CodeRabbit
