- Introduce StreamFsm class wrapping QProcess lifecycle with
Oneshot/Looping/Guarded restart policies
- Replace raw QProcess management in Ollie9pClient with StreamFsm
- Fix chatblockmodel FSM to properly handle [[[end]]] and fence
transitions with a combined State enum (Outside/InBlock/InFence)
- Add Q_INVOKABLE to setActiveSessionId for direct QML access
- Add streamfsm.cpp to CMakeLists.txt for both KF5 and KF6 builds
- Changed path from session/eventwait to /eventwait (global, not per-session)
- Use ollie-9p instead of plan9port 9p for the read
- Changed from parsing full session index to just calling refreshSessions()
on any event (the event format is now structured deltas, but the GUI
is kept simple with a full index refresh)
startStateStream now trusts the explicit session/agent selection and
opens session/<sid>/agent/<aid>/statewait directly. It no longer calls
getAgents(), which was repeatedly listing session/<sid>/agent on every
statewait reopen.
- Session row click now calls setActiveSessionId(id)
- setActiveSessionId no longer returns early for same-session clicks;
it always clears m_agentId and stops per-agent streams
- This enforces a clean 'session selected, no agent selected' state
- setActiveSessionId remains session-only and never starts streams
- setActiveAgentId now clears any existing per-agent streams and only
updates selection/state
- switchAgent is explicitly the only place that starts chat/statewait
- onStateFinished only reopens for the current explicit selection
- setActiveSessionId now selects only the session; it clears m_agentId
and never auto-selects a lone agent.
- startStateStream no longer re-resolves or falls back to another agent;
it only runs when the explicit active agent still exists.
- QML now handles activeAgentId changes explicitly and keeps the right
pane blank/disabled when no session or no agent is selected.
Add a run9p stat check before opening blocking reads on
statewait and chat. If the agent directory doesn't exist,
skip starting (prevents tight restart loops when a session
is killed while streams are active). Only one statewait
reader runs at a time.
onStateFinished and onChatFinished no longer restart their
streams. Streams are only started when the user explicitly
selects an agent (setActiveSessionId for single-agent,
switchAgent for multi-agent). This prevents tight restart
loops when pointing to a nonexistent directory.
- Deduplicate session entries in refreshSessions and onEventReadyRead
using QSet to skip duplicate session IDs from multi-agent index.
- Fix field mapping: index format is name\tstate\tcwd\tbackend\tmodel\tagent
- Added QSet include
- setActiveSessionId: only auto-select agent when exactly ONE exists.
With multiple agents, clear m_agentId and let user click on
an agent node in the tree to activate it.
- startStateStream: verify current agent directory still exists
instead of always re-discovering to the first agent. Only
fall back to first agent if current agent is gone.
- Emit activeAgentIdChanged so QML reacts to agent changes.
The previous fix stopped trimming the whole output but still called
.trimmed() on each individual line, which stripped trailing tabs from
empty-session lines like "testsession2\t\t\t\t\t". Now we split
by tab directly without any trimming — empty fields stay as empty
strings and the parts count stays at 6.
refreshSessions() and onEventReadyRead() called .trimmed() on the full
session/idx output, which stripped trailing tab characters from the
last line. An empty session line ("testsession2\t\t\t\t\t")
became just "testsession2" — a single field that failed the size>=2
check and was silently dropped from the session list.
- onEventReadyRead() now parses the eventwait data directly instead of
discarding it and re-reading session/idx
- Removed the 2-second refresh timer that was stealing focus from the
prompt text area on every tick
- ensureRootDataLoaded() now calls refreshSessions() so the initial
session list is populated immediately, not only on events
- Added '(no sessions)' placeholder label in the session tree ListView
when no sessions exist
- getAgents(): filter out 'new' (agent creation file), return empty list
- setActiveSessionId(): skip agent init when no agents exist
- submit/interrupt/kill/streams: guard against empty m_agentId
- prompt input: disable when no agent, show 'No agent' placeholder
Session-level kill (session/{id}/ctl) does the full cleanup:
removes from session map, cancels context, closes agent, kills
toolsrv process, removes persisted JSON. Agent-level kill just
cancels the session context without cleaning up the filesystem.
Also remove unused getAgents call.
- Add killSession(sessionId) Q_INVOKABLE to Ollie9pClient
- Accept right button in session tree MouseArea
- Context menu with Kill option on right-click
- MenuItem resolves session ID via parent chain
- New session dialog: Backend and Model now use proper ComboBoxes with
editable=true so users can type or select from dropdown
- Backend picker and model picker dialogs removed (no longer needed)
- Model list populated reactively via Connections on backend selection
- Fix model caching: m_rootModels[be].toStringList() returns a copy;
extract to local QStringList, append, store back into map
- Session creation uses correct path 'session/new' instead of 'new'
- Chat blocks are now collapsible: user/assistant/tool expanded by default,
reasoning/call/error/info/default collapsed
- Fix chat history on session switch: readLogForSession() reads from the
explicit session/agent path instead of relying on active state
- Fix delegate layout: use plain ColumnLayout instead of Item-wrapped
ColumnLayout so ListView calculates implicit heights correctly
- Add C++ methods: loadRootBackends(), loadRootAgents(), getAvailableModels(), createSession()
- Add Q_PROPERTYs for root data state (backends, agents, models)
- Add '+' button to sessions toolbar
- Create New Session Dialog with:
- Directory field + Browse button (FolderDialog)
- Name field (optional, auto-generated if empty)
- Backend combo (populated from /backends)
- Model combo (filtered by selected backend)
- Agent combo (populated from /agents)
- Remote field (user@host:port)
- Root data loaded lazily on startup
- OK creates session via 'write new' 9P call and refreshes list
- Add getAgents() to Ollie9pClient for listing agents per session
- Add switchAgent() for switching sessions+agents atomically
- Add activeAgentId property and activeAgentIdChanged signal
- Replace flat ListView with tree-aware model (session → agents)
- Session nodes expandable/collapsible with ▶/▼ indicator
- Agent nodes indented, clickable to activate that agent
- Active agent highlighted, active session auto-expanded
- State dots on both session and agent rows
Signals were emitted before m_agentId was set, causing QML's
onActiveSessionIdChanged handler to call readLog() with an empty
agent path. Now: discover agent → emit signals → start streams.
- KRunner: rewritten to use plan9port 9p command for all operations
(list sessions, kill, one-shot generate). No D-Bus dependency.
- Tray: removed. Was a thin D-Bus status wrapper, not useful enough
to justify maintaining.
- Plasmoid: removed. GUI is standalone now.
- Kate: temporarily disabled in CMake. Header partially converted to
9P (D-Bus includes removed, QProcess/9P helpers declared). Full
conversion is next.
- All ninepBin() helpers use $PLAN9/bin/9p (not hardcoded path).
- CMake: removed Qt5::DBus, KF5::Notifications, KF5::Plasma deps.
Only remaining link deps: Qt5::Core, Qt5::Widgets, Qt5::Quick,
Qt5::QuickControls2, KF5::Runner.
Kill the entire D-Bus rendering pipeline. The GUI now uses plan9port's
9p command as a subprocess for all server communication:
- Chat streaming: persistent 'read chat' process, readyReadStandardOutput
delivers tokens directly to QML (no polling, no signals, no offsets)
- State: 'read statewait' process, restarts on each state change
- Session list: 'read session/idx' one-shot
- Submit/stop/kill: 'write prompt/ctl' one-shot
The QML is stripped to fundamentals: session list + monospace streaming
text (last 8KB tail) + input field. No ChatBlockModel, no ThemeManager,
no OllieDBusClient, no syntax highlighting, no markdown rendering.
This eliminates the multi-second GUI freezes caused by:
- QTextDocument relayout on 200KB+ accumulated text
- loadEarlier cascade creating hundreds of delegates
- KSyntaxHighlighting::Repository blocking init
- Offset mismatch triggering synchronous D-Bus calls
Features will be re-added incrementally on this proven foundation.
D-Bus retained only for plasmoid/tray/KRunner (desktop integration).
