- Add 2.5 second heartbeat timer using Lib9pClient to read 'help'
- Heartbeat detects daemon death reliably (vs unreliable process exit codes)
- On disconnect: clear sessions, stop streams, reset active selection
- On reconnect: refresh sessions, restart agent streams
Replaces flaky NinePConnection::disconnected signal which depended on
eventwait process exit behavior.
- Add agentStateRevision property that increments on any state change
- QML binds to revision to trigger re-evaluation of agentState() calls
- All agent dots now show correct live state, not just active agent
- Add createSession(name, remote) with New Session dialog
- Remove agent connectivity code (redundant with session connectivity)
- Refactor NinePConnection as formal state machine with explicit events
- Fix silent restart to not cycle through Connecting state
Agent connection state is now derived from session.connected in session/idx,
updated via refreshSessions(). No longer spawns N processes for N agents.
- Remove m_agentConnections hash and per-agent NinePConnection instances
- Remove readAgentRecords() (dead code - agents come from session/idx)
- reconcileAgentConnections() now just updates m_agentConnected from m_sessions
This eliminates one ollie-9p process per agent, leaving only:
- 1 daemon eventwait stream (for all events)
- 1 chat stream (for active agent only)
- 1 state stream (for active agent only)
Replace subprocess spawning (run9p) with native 9P connection for hot paths:
- refreshSessions() - called on every sessionsChanged event
- loadRootBackends() - called on daemon connect
- loadRootAgents() - called on daemon connect
Lib9pClient wraps the Go shared library with a Qt-friendly C++ API.
Connection persists across operations, eliminating ~2-5ms per-call
process spawn overhead.
Requires libollie9p.so from parent repo's lib9p/ package.
- Parse new session/idx format with all data in one read:
name, id, paused, connected, cwd, backend, model, agents
- Handle delta events from eventwait instead of full refresh:
- session.{sid}.agent.{aid}.state -> update cache, emit signal
- Structural changes (new/kill/pause/resume) -> full refresh
- Remove per-agent statewait streams (eliminated N processes)
- Single eventwait stream handles all events via pubsub
This eliminates O(sessions * agents) synchronous reads per refresh,
replacing them with one read + incremental delta updates.
- Add Pause/Resume toggle to session context menu
- Gray agent dots when parent session is paused
- Disable input field with 'Session paused' placeholder when paused
- Preserve focus on prompt input during tree rebuilds
- Add per-agent statewait streams to track execution state
- Agent dots show: green=idle, orange=calling, blue=thinking
- Session dots show RPC connection health (unchanged)
- Use version counter pattern to force QML binding re-evaluation
Session selection now auto-selects first agent:
- Clicking a session row selects its first agent (not just the session)
- Auto-select at startup now picks first agent of first session
- Fixes issue where clicking session would clear agent and show empty chat
Improved UI feedback:
- Header shows 'Session / Agent' name instead of just state
- State indicator gray when no agent selected
- Placeholder message when no agent selected: 'Select an agent to view chat'
- Chat ListView hidden when no agent (shows placeholder instead)
- Input already disabled with 'No agent' placeholder (existing behavior)
Cleanup:
- Remove dead declaration reconcileAgentConnections(const QVariantList&)
Change createAgent to return error string (empty=success).
Replace standardButtons with custom footer so dialog stays open
on error, showing the message and letting the user adjust values.
Connection monitoring and all 9P operations now use immutable
session/agent UUIDs in paths instead of mutable display names.
The server resolves these via the new Aliases mechanism in findChild.
This fixes the disconnected-indicator bug after session rename:
connections no longer go stale when names change.
Removed dead sessionNameForId/agentNameForId helpers and the
m_agentConnectionPaths tracking (unnecessary with stable paths).
Rename operations no longer restart streams.
- 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
- 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
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).
