charset=UTF-8 Content-Transfer-Encoding: 8bit Security: - chmod broker socket to 0o700 after listen (multi-user protection) - Add mode:0o700 to all 16 production mkdirSync calls - Add mode:0o600 to broker/session state file writes - Validate --resume ID before using in file paths (path traversal) - Add 10MB buffer size limit on broker socket handlers (DoS) - Remove unnecessary shell:true from Windows taskkill Robustness: - Rewrite approval forwarding to use pending request map instead of dual-buffer (second data listener race condition) - Track target socket per pending approval request; only reject on matching socket disconnect - Add target socket validation on forwarded responses - Fix 60s broker approval timeout vs 1hr client timeout mismatch - Reject malformed responses missing both result and error fields - Log late/unknown forwarded response IDs - Clean up pending forwarded requests on broker shutdown - Keep broker stream exclusivity after client disconnect (prevent interleaved requests on shared app-server) - Cancel completion inference timer when non-final items arrive - Add error logging to signal handler, process termination, and resume-candidate discovery catch blocks - Handle realpathSync failure in resolveStateDir with fallback - Wrap copyFileSync in migration with try-catch - Create config directory before first config write - Move broker state persistence errors to call sites for proper handling (throw from helpers, try-catch in ensureConnection) - Gate discovery progress behind \!options.json for valid JSON output - Pass --dir option through to withClient in kill and review commands Type safety: - Export and deduplicate JSON-RPC type guards, PendingRequest, NotificationHandler, ServerRequestHandler (client.ts → broker-client.ts) - Add RpcError class to replace (err as any).rpcCode pattern - Add KnownThreadItem union and isKnownItem() guard to fix GenericItem poisoning discriminated union narrowing - Remove all 7 forced type assertions in events.ts and turns.ts - Type UserConfig fields precisely (ReasoningEffort, SandboxMode, ApprovalPolicy) and remove as any casts in applyUserConfig - Import BROKER_BUSY_RPC_CODE from broker.ts instead of redefining - Add warning log for invalid broker/session state shape - Check git exit status in getDiffStats - Log non-ENOENT errors in getUntrackedFiles --- src/approvals.ts | 2 +- src/broker-client.ts | 47 ++++----------- src/broker-server.ts | 129 ++++++++++++++++++++++++++-------------- src/broker.ts | 74 +++++++++++++++-------- src/cli.ts | 5 +- src/client.ts | 14 ++--- src/commands/kill.ts | 2 +- src/commands/review.ts | 2 +- src/commands/shared.ts | 26 ++++---- src/commands/threads.ts | 6 +- src/config.ts | 7 ++- src/events.ts | 64 ++++++++++---------- src/git.ts | 15 +++-- src/process.ts | 25 +++++--- src/threads.ts | 17 ++++-- src/turns.ts | 39 ++++++------ src/types.ts | 27 ++++++++- 17 files changed, 291 insertions(+), 210 deletions(-) diff --git a/src/approvals.ts b/src/approvals.ts index 6835234..91e061c 100644 --- a/src/approvals.ts +++ b/src/approvals.ts @@ -35,7 +35,7 @@ export class InteractiveApprovalHandler implements ApprovalHandler { private onProgress: (line: string) => void, private pollIntervalMs = 1000, ) { - if (!existsSync(approvalsDir)) mkdirSync(approvalsDir, { recursive: true });

The broker-server registers this callback on the app-server client to trigger immediate shutdown when the app-server dies, instead of sitting idle for up to 30 minutes rejecting every request. This ensures the next ensureConnection() spawns a fresh broker with a fresh app-server. The shutdownInitiated flag prevents double-shutdown when the intentional shutdown path (idle timeout, broker/shutdown RPC, SIGTERM/SIGINT) closes the app-server, which would otherwise trigger the onClose handler. --- src/broker-client.ts | 11 +++++++++++ src/broker-server.ts | 11 +++++++++++ src/client.ts | 15 ++++++++++++++- src/turns.test.ts | 1 + 4 files changed, 37 insertions(+), 1 deletion(-) diff --git a/src/broker-client.ts b/src/broker-client.ts index 7c1bf23..ac5fe36 100644 --- a/src/broker-client.ts +++ b/src/broker-client.ts @@ -169,9 +169,14 @@ export async function connectToBroker(opts: BrokerClientOptions): Promise void>(); + socket.on("close", () => { if (!closed) { rejectAll("Broker connection closed"); + for (const handler of closeHandlers) { + try { handler(); } catch { /* best effort */ } + } } }); @@ -245,6 +250,11 @@ export async function connectToBroker(opts: BrokerClientOptions): Promise void): () => void { + closeHandlers.add(handler); + return () => { closeHandlers.delete(handler); }; + } + async function close(): Promise { if (closed) return; closed = true; @@ -287,6 +297,7 @@ export async function connectToBroker(opts: BrokerClientOptions): Promise { + if (shutdownInitiated) return; + shutdownInitiated = true; + process.stderr.write("[broker-server] App-server exited unexpectedly — shutting down\n"); + shutdown(server).then(() => process.exit(1)); + }); + // ─── State ────────────────────────────────────────────────────────────── /** Socket that currently owns a pending request (waiting for response). */ @@ -245,6 +255,7 @@ async function main() { // ─── Shutdown ─────────────────────────────────────────────────────────── async function shutdown(server: net.Server): Promise { + shutdownInitiated = true; if (idleTimer) clearTimeout(idleTimer); // Reject all pending forwarded requests before closing sockets for (const [reqId, entry] of pendingForwardedRequests) { diff --git a/src/client.ts b/src/client.ts index 99beb99..e523aef 100644 --- a/src/client.ts +++ b/src/client.ts @@ -92,6 +92,9 @@ export interface AppServerClient { onRequest(method: string, handler: ServerRequestHandler): () => void; /** Send a response to a server-sent request. */ respond(id: RequestId, result: unknown): void; + /** Register a callback invoked when the connection closes unexpectedly + * (e.g. the app-server process exits).
