Adds ability to hide/show the session list sidebar:
- Ctrl+B keyboard shortcut
- Toggle button (◀/▶) in the chat header
- Sidebar collapses to zero width when hidden
- Rewrite README.md with accurate 9P-based architecture
- Remove all D-Bus dependencies:
- Update dolphin/ollie-ask to use ollie-9p rdwr generate
- Update kate/ollie_ghost.cpp to use ollie-9p rdwr complete
- Remove QDBusInterface from ollie_ghost.h
- Fix OllieGhostProvider constructor in ollie_kate.cpp
- Remove D-Bus comments from gui/main.cpp and kate/ollie_kate.cpp
- Remove QtDBus from CMakeLists.txt (KF5 and KF6)
- Delete D-Bus test scripts test-e2e.sh and test-peers.sh
- Clarify no system tray component exists
- Update build/install instructions with just commands
- 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 colored dot to session rows showing tool server RPC status:
green=connected, yellow=paused+connected, gray=paused, red=broken
- Remove vestigial agent.connected from model (was never displayed)
- Session-level connected status is the correct granularity
Non-selected agents show idle (green). This matches the working
top indicator approach until we find a proper solution for tracking
all agent states reactively in QML.
- 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
- Update parentPaused on agents during incremental session updates
- Set parentPaused and parentExpanded when inserting new agents
- Update session paused property during updates
- Use explicit === true check for parentPaused
- Agent dots in tree are gray when parent session is paused
- Top state indicator is gray when viewing agent in paused session
- Top state label shows 'inactive' instead of agent state when paused
Previously disconnected was only emitted when entering Disconnected state,
not when transitioning Connected->RetryWait. This caused Lib9pClient to
keep a stale handle when olliesrv restarted, preventing reconnection.
- 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
Removes the activeState !== 'idle' check before sending the stop
command. The server-side Interrupt() is safe to call on an idle
agent (returns false, no-op).
This fixes an intermittent issue where pressing ESC wouldn't stop
the agent because the GUI's cached activeState was stale/out-of-sync
with the server's actual state.
- onAgentStateChanged: update specific agent in model instead of version bump
- State dot: use model.state directly instead of ollie.agentState() callback
- Remove ollie.isSessionPaused() call (was O(n) iteration per agent)
- Remove unused agentStateVersion property
Before: 1 state change → re-evaluate ALL agent dots → N * ollie.agentState() calls
After: 1 state change → setProperty on 1 model item → 1 binding update
- Check if event is for active agent FIRST using QStringView comparison
- Active agent: compare payload directly against m_activeState (no hash lookup)
- Non-active: use iterator find() to avoid double hash lookup
For the most common case (active agent state change), this reduces
the hot path to: QStringView compare → QString convert → direct compare
- Use QStringView to avoid string allocations during parsing
- Use QLatin1String for comparisons (faster than QString)
- Manual indexOf parsing instead of split('.') allocation
- Early return for non-session events
Reduces allocations in the agent.state hot path from ~7 QStrings
to 4 (only when state actually changes and needs to be stored).
Consolidate refreshSessions() to do everything in one iteration:
- Parse session/idx data
- Update m_agentConnected cache
- Track active session/agent existence
- Emit connection state change
Eliminates separate reconcileAgentConnections() call and second loop
to check active session/agent. O(n) instead of O(3n).
- computeConnectionColor() in QML instead of ollie.sessionConnectionColor()
(avoids O(n²) iteration through sessions list)
- Use agent.state from session/idx data directly instead of ollie.agentState()
(avoids hash lookup per agent per update)
All data now flows from session/idx through m_sessions to QML with no
callbacks into C++ during the update loop.
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.
Instead of clearing and rebuilding the entire session tree model on
every sessionsChanged signal, diff old vs new and:
- Update existing session/agent properties in place
- Remove deleted sessions/agents
- Append new sessions/agents
This avoids O(n) model rebuilds that cause ListView to re-render all
delegates, improving responsiveness with many sessions.
- Remove console.log statements from hot paths
- Add sessionExpandedCache for O(1) expanded state lookup
- Replace O(n) parentSessionExpanded() loop with cache lookup
- Preserve expanded state across session tree rebuilds
- 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
- Green: connected and not paused (healthy)
- Gray: paused (intentional)
- Red: not paused but disconnected (crashed/broken)
- Yellow: paused but still connected (zombie)
- Fetch paused status from session/{id}/paused file
- Gray dot indicator for paused sessions (green otherwise)
- Session names now show agent count: 'ollie (2)'
- Fixed rename to use baseName for sessions (without count suffix)
commitRename now checks the return value from renameSession/renameAgent.
On failure, resets displayName to the old value and shows an error dialog
explaining the rename failed (e.g., name already in use).
refreshSessions now checks if the active session/agent still exist after
updating the list. If the agent was killed, clears m_agentId and stops
streams. The statewait guard will then return false, stopping the loop.
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&)
Reworked ChatBlockModel to fix syntax highlighting issues:
- Replace regex-based renderMarkdown() with line-by-line fence parsing
- Code fences detected by ```lang (open) and ``` alone (close)
- Prose wrapped in <div> with explicit palette text color
- Code blocks syntax highlighted with KSyntaxHighlighting
HtmlHighlighter improvements:
- Add defaultColor for unhighlighted text spans
- Track offset to emit gaps between highlighted tokens
- Add endLine() to flush trailing unhighlighted content
Remove TextEdit color property that was overriding inline styles in Qt5.
Qt5's TextEdit 'color' property can override inline styles from RichText,
breaking syntax highlighting colors. Remove the property so inline color
spans from KSyntaxHighlighting are respected.
Default text color should come from the application palette.
Agent connections were using retryMs=0, causing a tight loop when the
/connection file read failed (e.g., toolsConn nil). The loop was:
connection fails → disconnected signal → refreshSessions →
reconcileAgentConnections → new connection → fails immediately → repeat
Fix by:
- Add maxRetries parameter to NinePConnection::start()
- Use 5s retry interval with max 3 retries for agent connections
- Reset retry count on successful connection
Three fixes:
1. Disconnect signals before stopping removed connections in
reconcileAgentConnections — prevents disconnect->refresh loop.
2. Clear m_activeSessionId/m_agentId when killing the active
session — guard function returns false, statewait stream stops.
3. Same disconnect-before-stop in stopAgentConnections.
Agent connections no longer retry on their own. When an agent is
killed, the connection goes to Disconnected and stays there.
reconcileAgentConnections (triggered by refreshSessions) is the
sole authority for creating/removing connections.
For the happy path (probe returns normally), the connection
immediately re-probes without a timer delay.
When an agent connection drops (killed or server restart), refresh
the session model from idx rather than immediately marking the
session as disconnected. This avoids a transient red indicator
when an agent is killed but the session is still alive.
The daemon disconnect handler (server down) still correctly marks
everything as disconnected.
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.
