Sub-agents now clone the parent agent's conversation history into
their initial context. The tool script passes parent=$OLLIE_UNAME
automatically. Mechanically identical to session restore — uses
RestoreHistoryFromMessages on the parent's Messages().
Writing to session/{s}/agent/new with a prompt= key now blocks
until the agent completes its task, then returns the reply and
destroys the transient agent. Without prompt=, behaves as before
(creates agent, returns ID).
Also:
- Move ParsePayload/UnescapeValue to shared ollie/toolsrv package
- Remove duplicate implementations from cmd/toolsrv/internal/server
- Add session.CreateAgentWithParams for direct AgentParams usage
- Eliminate flattenParams/unescapeValue redundancy in fs package
Read, Write, and Rdwr are the three atomic 9P operations:
- Read: non-blocking read
- Write: non-blocking write (fire-and-forget)
- Rdwr: atomic write-then-read (blocking, produces result)
BlockOnce and Stream are special cases of Read.
Rdwr is its own primitive — not a variant of either.
ListProcs now does rdwr to toolsrv proc/list with the agent ID.
Returns pre-formatted text. Ctl proc handler uses it directly.
Removed all ListDetachedRaw map-parsing logic.
- Remove /tools from olliesrv root (toolsrv owns all tool state)
- Add /all file to toolsrv namespace (lists all available tools on disk)
- Add ListAllTools() to toolsrv client library
- Add tools_all ctl command to agent (reads from toolsrv/all)
- Update system prompt with tools_all usage
Same pattern as BlockOnce: framework handles the blocking loop.
readFn takes a base string, returns (data, nextBase, error).
signal fires when new data may be available.
Chat stream handlers now use Stream(a.ChatRead, a.ChatSignal).
StreamRaw retained for custom handlers.
streamChat() in support.go is now dead code (replaced by ChatRead).
BlockOnce now takes a value-reader and a signal source. The framework
handles the blocking loop: read → compare hash to base → if different
return → else wait on signal or timeout.
On timeout (ctx.Done), returns empty (not error) so clients re-open
cleanly.
BlockOnceRaw retained for queue-style handlers (bypass/pending,
proc/wait) that manage their own blocking.
EventValue adapter wraps a <-chan Event into BlockOnce-compatible
(readFn, signalFn) pair via a thin goroutine.
- BlockOnce handler initializes base to current hash on fresh open,
then blocks until hash changes. Same pattern as statewait.
- ConsumeFeed is a plain function: dials 9P, reads feed in a loop
(open → block → data → close → repeat), submits to agent.
- Context cancellation closes the 9P client, unblocking Read().
- Called as go ConsumeFeed(ctx, ag) from AddAgent and session resume.
Feed is now read-write (0666):
- Write: store data, signal via notifyChange
- Read (BlockOnce): block until content hash differs from base
Dedup lives in the read layer (same pattern as statewait). The
internal consumer goroutine and external 9P clients both call
FeedBlockingRead — same codepath, same dedup logic.
Consumer started from AddAgent (if ctx available) and session resume.
Feed is a write-only file in the agent namespace. Writes are
deduplicated against the previous value; the internal consumer
(blocking on WaitChange/WatchFeed) only wakes when genuinely new
data arrives.
Wiring is external and source-agnostic:
# human → observer (poll git):
while :; do git diff HEAD; sleep 5; done | ollie-9p write .../feed
# agent → observer (stream chat):
ollie-9p read .../coder/chat | ollie-9p write .../observer/feed
Uses the agent's existing signalCh/notifyChange plumbing — no new
channel infrastructure. Consumer goroutine spawned at agent creation
(AddAgent) and session resume, tied to session context.
Fix holes where queued prompts were orphaned:
- After turn loop exits (interrupt, toolsrv unavailable), drain remaining FIFO items
- On panic recovery, pop next FIFO item and re-submit in a new goroutine
- fifo file write triggers Submit when agent is idle
- Detach background proc context from request context so processes survive
after the 9P request returns (fixes premature SIGTERM)
- Add /proc/list file to toolsrv showing all procs with state
- Show status (running/exited (N)) in agent proc list
- Keep exited procs in tracker until explicitly dismissed
- Skip 'list' entry in ListDetachedRaw
- Remove olliesrv's bypass broker machinery (pendingCh, EvaluateRequest, etc)
- Session bypass loop now just reads from toolsrv's bypass/pending and notifies
- Notification handler writes directly to toolsrv's bypass/resolve (fire and forget)
- Remove bypass/ directory from olliesrv's 9P namespace
- Remove session/*/bypass file (policy can be added back to toolsrv later if needed)
The flow is now:
1. toolsrv blocks tool execution, exposes request via bypass/pending
2. olliesrv reads from toolsrv, shows D-Bus notification
3. User clicks approve/deny, olliesrv writes to toolsrv's bypass/resolve
4. toolsrv unblocks and executes (or denies)
- Added BlockingReadMode() and StreamMode() handling to toolsrv's handleRead()
- Made NextPending() context-aware in both toolsrv and olliesrv bypass packages
- This fixes the bypass approval flow via 9P - reads now properly block until
a request is available and respect context cancellation
Remove RequestCtx variant - all Request handlers now take context.
This is required for proper cancellation of blocking operations
like tool execution when the client disconnects or stop is called.
- Removed session/connected (used blocking Ping() on potentially stale conn)
- Removed per-agent tools file (tool management now via toolsrv ctl)
- Fixed session/idx: replaced blocking IsConnected() with non-blocking
toolsConn != nil check, preserving the field for GUI compatibility
- Removed dead IsConnected() method from session.Session
The namespace spec is now fully self-contained. Every handler is a
closure right where it's declared — no jumping between files.
Deleted: handlers_root.go, handlers_session.go, handlers_agent.go, ctl.go
Added: support.go (shared utilities: mergeCtx, streamChat, stripMarkers,
dispatch, wireAgentEvents, help memoization)
spec.go grew to ~920 lines but is now the single source of truth for
the entire 9P namespace. Know where to look.
Each() now returns []FsNodeDecl directly. The Binding type was a
redundant subset of FsNodeDecl with a slightly different Remove
signature. Dynamic entries are now expressed uniformly — Remove,
Rename, Children, Aliases all live on FsNodeDecl like everything else.
Also added: Alias() and RenameNode() options, DirNode accepts
[]FsNodeDecl for passing pre-built child slices.
SessionNode now embeds *session.Session instead of wrapping it.
All delegation methods (ID(), Name(), Ctx(), Pause(), etc.) are removed.
Handlers access session fields/methods directly through promotion.
Moved pause/resume event publishing into session.Session itself since
the session package already owns PublishEvent.
Eliminated all s.Session.X stutter from handler code.
Handlers now accept their actual dependencies directly:
- Root handlers: ModelCache, Broker, context.Context, etc.
- Session handlers: *SessionNode, removeFn, renameFn
- Agent handlers: *agent.Agent, *AgentLog, *SessionNode
Ctl dispatch tables are now per-instance closures built at binding
time rather than package-level vars with generic Hctx.
Also inlined the intermediate internalBinding type — adapt functions
now build fsedsl.Binding directly from raw data.
Removed: Hctx struct, rdwrHandler type, rdwrDispatch func,
bypassBindings helper, processBindings helper, internalBinding type.
Converted the entire 9P namespace spec from progressive Hctx population
to closure capture. Handlers are now closures that capture their
dependencies (session, agent, etc.) at binding time.
Hctx remains as a transitional adapter — handlers still receive it,
but it's constructed per-call from captured state rather than threaded
through the tree. Will be removed in a follow-up once handlers are
converted to use captured state directly.
- Timeout: timeout=0 means no deadline (was defaulting to 30s)
- Signal: send to process group (-pgid) not just process; SIGTERM no longer
cancels context (only SIGKILL does); cmd.Cancel sends SIGTERM with 5s WaitDelay
- Streaming: background procs stream output in real-time via procWriter;
shell tool no longer buffers all output into a bash variable
- Proc tree: olliesrv exposes proc/{id}/out, proc/{id}/ctl, proc/{id}/status
as proper 9P directory (was broken flat file)
- Connection: proc handlers dial fresh toolsrv conn per request via
Session.DialToolServer() to avoid deadlocking the agent's blocked conn
- Stat format: key=value (exited=true, exit_code=N, id=N) matching client parser
- GC: procs auto-removed 10min after LastRead (exited procs only)
- Rename: PID -> ID throughout (synthetic, not OS PID)
- Ctl commands: term (SIGTERM), kill (SIGKILL), signal <n>, dismiss
- System prompt: correct ollie-9p commands for proc management
Add /session/{sid}/agent/{aid}/tools file:
- Read: list loaded tools for this agent
- Write: load a tool by name
Also add missing tool_load to justfile install.
