Replace the synchronous /edit (wait for full markdown response) with an
async + SSE flow per demo.html so the user sees text stream in real-time
and can interact with permission/question events the agent raises.
Backend
-------
- EditHandler now calls OpenCode /session/:id/prompt_async and returns
immediately with {ok, sessionId, notebookPath}; the LLM reply is no
longer embedded in this response.
- New GlobalEventHandler proxies OpenCode /global/event as
text/event-stream. Server forwards ALL events; the client filters.
A too-eager server-side ?session= filter was silently dropping events
the client would have accepted, so it was removed.
- New PermissionReplyHandler + QuestionReplyHandler forward user
replies (once/always/reject and freeform answer) back to OpenCode
Serve at /session/:sid/permissions/:permId and
/session/:sid/question/:qId/reply.
- OpenCodeClient gains send_message_async(), stream_global_events()
(async generator over the SSE feed via tornado streaming_callback),
reply_permission() and reply_question(). Legacy send_message_sync
removed.
Frontend
--------
- subscribeOpenCodeEvents() opens a fetch+reader SSE client (XSRF
token injected from serverSettings); AbortController-backed close()
is idempotent.
- OpenCodeInlinePrompt.applyEvent() routes events into the streaming
UI: text delta -> assistant message (re-rendered as markdown on
every delta so the user sees formatted <pre><code> blocks in
real-time, not raw fence source); reasoning/tool/permission/question
get collapsible details blocks. session.idle resets stream pointers
and fires onStreamEnd.
- Permission/question blocks render real interactive UI: three
buttons (once/always/reject) for permission, a text input + submit
for question. Click handlers post through the new API routes and
show success/failure status in place.
- Centralized idle detection (4 shapes: top-level + payload-nested
x {session.idle, session.status/idle}) inside the prompt; cell
action reacts via onStreamEnd callback rather than re-parsing
event types.
- System / workspace / pty / lsp / mcp / installation events AND
session-level control events (agent.switched, model.switched,
file.edited) are not rendered in the frontend.
Tests
-----
- 52 backend pytest (was 43)
- 58 frontend jest (was 46)
design.md section 3 updated for the new async /edit response shape
and the new GET /events SSE endpoint.
