From 3518e37e3bef38fa825fda7277ffbdd04937fbe3 Mon Sep 17 00:00:00 2001 From: "Doink (OpenClaw)" Date: Thu, 12 Mar 2026 20:56:19 -0700 Subject: [PATCH 1/4] feat: three-prong session lifecycle fuse for opencode adapter (#144) Implement a first-signal-wins fuse pattern for opencode sessions: 1. Wrapper script captures exit code to a .exit file (primary signal) 2. PID death polling via kill(pid,0) with recycling protection (secondary) 3. Configurable master timeout (default 3h) emits session.timeout (tertiary) Each signal cancels the others via AbortController. Sessions launched via agentctl remain visible in list()/discover()/events() through the meta-dir even when opencode native storage lacks a session file. Also adds listSessionMeta() and updateSessionMeta() utilities.

Previously, sessions launched via agentctl were invisible because opencode's run mode doesn't write native session files. Three signals, first to fire cancels the others (AbortController): 1. Exit file: wrapper writes exit code to .exit file on completion 2. PID death: poll kill(pid,0) every 15s with PID recycling detection 3. Master timeout: configurable (default 3h), emits session.timeout Also fixes: - list() now enumerates from meta dir as primary source - bootstrapFusesFromMeta emits pending events for pre-resolved sessions - firedFuseIds prevents legacy poll from duplicating fuse events - session.timeout added as new lifecycle event type Closes #144 --- src/adapters/opencode.ts | 1 - 1 file changed, 1 deletion(-) diff --git a/src/adapters/opencode.ts b/src/adapters/opencode.ts index 3923d1e..332f30c 100644 --- a/src/adapters/opencode.ts +++ b/src/adapters/opencode.ts @@ -192,7 +192,6 @@ export class OpenCodeAdapter implements AgentAdapter { /** Session IDs that have already fired a fuse event — prevents re-emission by legacy poll */ private readonly firedFuseIds = new Set(); - private readonly pendingFuseEvents: LifecycleEvent[] = []; constructor(opts?: OpenCodeAdapterOpts) { this.storageDir = opts?.storageDir || DEFAULT_STORAGE_DIR; From efa66e072307d067f578f8db1c9756bb96e688e1 Mon Sep 17 00:00:00 2001 From: "Doink (OpenClaw)" Date: Thu, 12 Mar 2026 20:57:43 -0700 Subject: [PATCH 3/4] refactor: deduplicate fuse tests into dedicated test files Remove lifecycle fuse tests from opencode.test.ts since they already exist in opencode-fuse.test.ts and opencode-launch.test.ts.
