WalkthroughDraft message creation and deletion now trigger pre-request hooks. Offline persistence and global state update optimistically. Draft events use channel and parent identifiers for storage operations. Tests cover hooks, persistence, state changes, and event handling. ChangesDraft request hooks
Offline draft persistence
State and event handling
Estimated code review effort: 3 (Moderate) | ~25 minutes Merge Risk: 🟡 Moderate · up to Draft deletions during history synchronization can leave stale drafts visible in channel or thread state, so the PR is not merge-ready until those state updates and corresponding tests are fixed.

Lines 73-74 and Lines 90-92 describe the channel and message as updated. These hooks delete a draft. Describe them as deleted.

- Around line 100-116: Strengthen the no-op assertions in
DraftMessageListenerDatabaseTest.kt lines 100-116 by verifying
messageRepository.insertDraftMessage is never called, alongside
deleteDraftMessage. In DraftMessageListenerStateTest.kt lines 92-108, also
verify updateDraftMessage is never called, alongside removeDraftMessage, so both
tests cover the complete no-mutation contract.
In
`@stream-chat-android-state/src/main/java/io/getstream/chat/android/state/event/handler/internal/EventHandlerSequential.kt`:
- Around line 926-932: Update the history-sync handling in
EventHandlerSequential so DraftMessageUpdatedEvent and DraftMessageDeletedEvent
also update global draft state via mutableGlobalState.updateDraftMessage and
removeDraftMessage, using the unfiltered event list while preserving
offline-storage persistence. Add history-sync coverage for both channel and
thread drafts, including deletion cleanup from channelDraftMessages and
threadDraftMessages.

Goal
Backport of #6625 to
v6: draft messages are lost when a request does not complete, and reappear after they have been deleted.Closes AND-1373
Implementation
Same fix as #6625, with the offline and state parts landing in
stream-chat-android-offlineandstream-chat-android-state, which are still separate modules onv6.Two additions, since
MessageRepositoryandDraftMessageListenerare part of the public API dump onv6but not ondevelop:MessageRepository.deleteDraftMessage(cid, parentId)gets a default body that resolves the draft through the existing select methods before deleting it, so custom repositories keep compiling and get the fix.DatabaseMessageRepositoryoverrides it with a single-query delete.DraftMessageListenerhooks get no-op default bodies.The module compiles with
-Xjvm-default=all, so both are real JVM default methods and already-compiled implementations keep working.Testing
Unit tests cover both precommit paths, the channel and thread cases for
draft.deleted, the repository default, and the new draft DAO queries against a real database.Summary by CodeRabbit
