Sessions are saved to ~/.local/share/ollie/sessions/active-9p/ on
shutdown and restored on startup. Core auto-saves to SessionsDir
during turns. KillSession removes persisted files.
Closes the major feature gap with the D-Bus daemon.
- ls /s/{id}/proc/ lists detached PIDs
- cat /s/{id}/proc/{pid} reads ring buffer output
- rm /s/{id}/proc/{pid} dismisses the process
- echo detach > /s/{id}/ctl detaches running process
- echo "signal {pid} [TERM|KILL]" > /s/{id}/ctl signals detached process
Walk validates PID exists in detached list before succeeding.
content() holds sess.mu.RLock, then calls CachedListModels which
tried to acquire sess.mu.Lock for cache write — classic RLock/Lock
deadlock. Fix by giving the models cache its own mutex independent
of the session mu.
- Add CachedListModels() with 24h TTL to avoid repeated Models() API calls
- Cache readdir serialized bytes per-fid (rebuild only at offset=0)
- Skip all session file size computation in makeStat (report len=0)
- Short-circuit pathType() for session paths to avoid triggering Stat
- Remove e.Info() call from subdirectory readdir (unused mtime)
- Add monotonic timer to handle() for profiling 9p operations
- Add fcallTypeName() helper
- Fix stubCore for new Detach/SaveSession interface methods
- Add tools-process.md prompt
Before: ls inside a session dir took 1.38s (kiro) / 67ms (openrouter)
After: 182µs regardless of backend (7500x improvement)
Remove a/, p/, sk/, m/, tr/, tmp/, u/, x/, and per-session t/ from the
9P namespace. These are all files on disk that the runtime reads directly
from ~/.config/ollie/ — serving them through 9P added indirection without
value.
What remains:
- /s/ (live sessions: the dynamic state that doesn't exist on disk)
- /backends, /models, /help (synthetic root files)
This brings olliesrv's scope in line with the D-Bus daemon: session
lifecycle, prompt submission, state observation, and streaming output.
Created session/mount.go with all 9P FUSE mount logic previously in core.
Changes:
- New session/mount.go with MountPathFor(), WithMount9P(), and mount lifecycle functions
- WithMount9P() returns execute.Option that wires up OnEnvSet, OnPreDispatch, OnClose hooks
- Updated session.go to use WithMount9P() and MountPathFor() instead of execute.WithMount() and execute.MountPath()
- Mount logic encapsulated in mountState struct with proper synchronization
The mount implementation is now fully contained in the 9p module.
- Wire ReadPlanStep directly from sess.plan (no filesystem read)
- Add ListHandlers to ManagerConfig; passed through to AgentCoreConfig
- Hoist skillTree in main.go; populate ListHandlers for tools+skills
- Add ListHandlers to ManagerConfig
- Add ModelCache that prefetches models from all backends at startup
- Cache models in memory, refresh on demand via Invalidate()
- Add global /ctl file with 'invalidate' command
- Add 'invalidate' ctl command and /invalidate slash command in sessions
- Fix filePerm to query rootStore for root-level file permissions
- Add 'models' to root directory listing
- NewSession subscribes to bus "event" topic for chat log writing
- Remove makePublish/handler threading from all Submit call sites
- Adapt tests to new bus-based event delivery
- server.New takes server.Config (no more internal construction)
- OnRename removed: wstat handles all fid rewriting directly
- WithStrict/WithYolo removed (passed via ManagerConfig)
- Default dir functions moved to main.go
- tool.go and root.go in main package (wiring)
- Server is now a pure protocol handler
