Delete Branch "%!s()"
Deleting a branch is permanent. Although the deleted branch may continue to exist for a short time before it actually gets removed, it CANNOT be undone in most cases. Continue?
Objective
Perform a full debug audit of the entire
MATTERMOST_OPENCLAW_LIVESTATUSrepo.Scope: Read-only analysis only. The live status system is working correctly as of 2026-03-09. The goal is to surface latent bugs, edge cases, race conditions, and code quality issues — not to change anything that affects current behavior.
Critical constraint: Do NOT change the functional logic of:
src/status-watcher.js(file offset tracking, lock file events, idle detection)src/session-monitor.js(_knownSessions, _completedSessions, clearCompleted)src/watcher-manager.js(session-added handler, lock event wiring)plugin/server/store.go(KV cleanup goroutine)These files were surgically fixed today. Any refactor risks breaking the live system.

PROJ-038 Worker 2: Go Plugin Server Audit -- Race Conditions, Goroutine Leaks, KV Consistency
Audit of plugin/server/*.go. 14 findings across CRITICAL/HIGH/MEDIUM/LOW severity.
[CRITICAL] Race condition on botUserID
[CRITICAL] Goroutine leak: OnDeactivate called before OnActivate
[HIGH] TOCTOU in ListAllSessions: KVList then KVGet per key
[HIGH] OnDeactivate marks done/error sessions as interrupted
[HIGH] URL path injection in session key extraction
[HIGH] WebSocket broadcast: lines ([]string) may not gob-encode safely
[MEDIUM] defer Body.Close after io.ReadAll (wrong idiom)
[MEDIUM] O(n) activeCount scan per handleCreateSession
[MEDIUM] Overlapping CleanStaleSessions cycles
[MEDIUM] updatePostMessageForMobile goroutine races with handleDeleteSession
[MEDIUM] encodeKey: url.PathEscape + KV key length limit
[LOW] writeJSON does not set Content-Length
[LOW] getBotUserID: unprotected read of botUserID
[LOW] handleDeleteSession: UpdatePost errors silently discarded
Items checked and found non-issues: main.go (trivial), configuration.go (locking correct), CleanStaleSessions zero-timestamp handling (correct), broadcastUpdate children_json pattern (correct -- this is the RIGHT approach that lines should also follow).

AUTO_AUDIT + SIMULATION Report
AUTO_AUDIT Results (28/28 PASS)
Completeness: All phases have success criteria, concrete deliverables, and time estimates. No vague phases. Final phase includes verification.
Dependencies: GITEA_TOKEN available and verified. No circular dependencies. No blocking human inputs -- audit proceeds autonomously.
Feasibility: All source files accessible via Gitea raw API (confirmed during research). No file creation prerequisites. No elevated permissions needed.
Security: No secrets committed. All output scanned via sensitivity-scanner.sh before Gitea posting. GITEA_TOKEN referenced by env var only. No repos created.
Risks: All phases are read-only (code review + comments). Phase isolation -- failure in P3 does not affect P1-P2. No uptime-affecting changes. No data loss risks.
Result: ALL PASS -- plan is safe to execute on approval.
SIMULATION (Dry-Run Narrative)
Phase 1 -- Node.js audit (90 min)
Read all src/*.js files via Gitea raw API (already completed during research phase). Post structured findings comment on issue #9.
Pre-confirmed findings from research:
src/status-box.js_httpRequest(): HTTP requests have no socket timeout. If Mattermost accepts TCP but never sends a response, the Promise never resolves. StatusBox accumulates un-flushed resolvers indefinitely. No retry fires. Daemon appears stuck. MEDIUM severity.src/plugin-client.jserror handler in watcher-manager: any HTTP error from the plugin (including 429) triggersbox.usePlugin = false-- permanent REST fallback for that session. A transient rate limit should not permanently disable plugin mode. MEDIUM severity.src/watcher-manager.jssaveOffsets(): write errors are silently swallowed with no log. On disk-full scenarios, offsets are never persisted and restart recovery silently fails. LOW severity.src/watcher-manager.jscheckChildrenComplete(): returns true if box.children is empty. Sub-agents in pendingSubAgents are not in box.children yet. If parent goes idle while sub-agent is still queued, parent is marked done prematurely. LOW severity (rare timing edge case).src/session-monitor.js_dmChannelCache: grows without eviction. Long-running daemon with many unique user IDs accumulates unboundedly. LOW severity.src/watcher-manager.jsoffset save interval: setInterval 30000ms is never cleared in shutdown. Extra fire during long flushAll could write to partially-torn-down state. LOW severity.Simulation result: comment posted, 201 verified, proceed to P2.
Phase 2 -- Go plugin audit (60 min)
Review all plugin/server/*.go files. Post findings comment on issue #9.
Pre-confirmed findings from research:
plugin/server/plugin.goOnDeactivate():close(p.stopCleanup)has no guard against double-call. If the Mattermost framework calls OnDeactivate twice (rapid plugin toggle), second call panics with "close of closed channel". Fix: use sync.Once. MEDIUM severity.plugin/server/api.gohandleUpdateSession():go p.updatePostMessageForMobile(...)-- one goroutine spawned per update call. During streaming (many updates/sec, many concurrent sessions), this generates a burst of concurrent API calls to Mattermost with no rate limiting or deduplication. Could cause the plugin to hit Mattermost rate limits and worsen the "(edited)" label problem. MEDIUM severity.plugin/server/api.gohandleDeleteSession(): callsp.API.GetPost()andp.API.UpdatePost()synchronously in the HTTP handler. If Mattermost API is slow or rate-limiting, this blocks the daemon's deleteSession request, stalling session cleanup. LOW-MEDIUM severity.plugin/server/store.goCleanStaleSessions(): errors from SaveSession/DeleteSession inside the loop are discarded with_ =. Silent failure during KV unavailability. LOW severity.plugin/server/api.gohandleCreateSession(): TOCTOU race on MaxActiveSessions count check. LOW severity (daemon serializes creates in practice).plugin/server/websocket.go: payload key is"children_json"(JSON string). Butplugin/webapp/src/types.tsWebSocketPayloaddeclareschildren: LiveStatusData[]. At runtimedata.childrenin index.tsx is always undefined. Children are NEVER rendered in the webapp. CONFIRMED BUG -- MEDIUM severity.Simulation result: comment posted, 201 verified, proceed to P3.
Phase 3 -- Webapp audit (45 min)
Review index.tsx, types.ts, live_status_post.tsx. Post findings comment on issue #9.
Pre-confirmed findings:
plugin/webapp/src/index.tsxL43:children: data.children || []silently masks the children_json bug from P2(f). Fix requires either: parse children_json in index.tsx, or change websocket.go to serialize children as a JSON array directly. MEDIUM severity.plugin/webapp/src/components/live_status_post.tsxelapsed counter: initial elapsed state is 0, causing a 1-second gap on first render before counter shows real value. Cosmetic LOW severity.splice(idx, 1)in useStatusUpdates is safe -- no iteration-during-mutation issue. PASS.Simulation result: comment posted, 201 verified, proceed to P4.
Phase 4 -- Startup/shutdown audit (30 min)
Pre-confirmed findings:
start-daemon.sh:export PLUGIN_SECRET="${PLUGIN_SECRET:-}"exports empty string if unset. Daemon sendsAuthorization: Bearer(empty bearer). Plugin rejects all daemon requests. Daemon silently falls back to REST with no warning. Operators may think plugin mode is active when it is not. LOW severity (fallback works) but operability concern.if (shuttingDown) return-- PASS.Simulation result: comment posted, 201 verified, proceed to P5.
Phase 5 -- Edge cases audit (45 min)
Pre-confirmed findings:
updatedAtin sessions.json: _completedSessions suppresses re-detection indefinitely. Recovery depends on the ghost fs.watch firing (which requires a daemon restart to set up, or an existing watcher). MEDIUM severity -- depends on OpenClaw sessions.json format contract.Simulation result: comment posted, 201 verified, proceed to P6.
Phase 6 -- Summary (30 min)
Collate all findings. Post ranked summary table. Verify 201 response.
Simulation verdict: NO BLOCKERS -- all phases are safe and mechanically sound. Ready to execute on Rooh approval.

Worker 6: Offset File Edge Cases — Audit Complete
9 findings total: 2 [CRITICAL], 3 [MEDIUM], 4 [LOW]
[CRITICAL] Graceful Shutdown Does Not Persist Offsets
shutdown()stops the watcher and marks boxes interrupted, but never callssaveOffsets. The last save for active sessions was up to 30 seconds prior (from the periodic interval). Any sessions active at shutdown lose their offsets.saveOffsets(config.offsetFile, watcher.sessions)at the top ofshutdown(), beforewatcher.stop().[CRITICAL] Idle Handler Calls removeSession Before saveOffsets — Completed Session Offset Not Persisted
watcher.removeSession(sessionKey)is called on line ~503, which deletes the session fromwatcher.sessions. ThensaveOffsets(config.offsetFile, watcher.sessions)is called on line ~510. The save iterates the map that no longer contains the completed session.saveOffsetsto beforewatcher.removeSession, or save the completed session offset separately before removing it.[MEDIUM] No Atomic Write — Partial Write on Crash Corrupts Offset File
writeFileSync, the offset file is left truncated.JSON.parsethrows on next startup, catch returns{}, all offsets silently discarded..tmpfile thenfs.renameSyncover the real path. POSIX rename is atomic — the original is never corrupted.[MEDIUM] Stale Saved Offset Larger Than Replaced Transcript File
_readFilehandlesfileSize < lastOffset(truncation/compaction — resets to file end). But if a transcript file is replaced with a new file that is LARGER than the saved offset, the truncation check passes and reading starts from byte N of the new file — not from a line boundary. The chunk is parsed as JSONL and produces garbage or silent parse errors.lastOffset. On recovery, if the value has changed, treat as a new session (start from file end) rather than restoring the stale offset.[MEDIUM] Race: Session in Both completedBoxes and savedOffsets
session-addedhandler checkscompleted(in-memory completedBoxes) first. If truthy, it setsinitialState = { agentId }(no offset) and theelse if (savedState)branch is skipped. If a session is in both completedBoxes (current run) and savedOffsets (startup load), the saved offset is silently ignored.[LOW] Offset File in /tmp — Lost on Reboot
/tmp/status-watcher-offsets.json. Cleared on reboot on most Linux systems using tmpfs./var/lib/openclaw/status-watcher-offsets.json. Document OFFSET_FILE env var.[LOW] Silent Error Suppression in loadOffsets Masks Permission Issues
loadOffsetscatches ALL errors (including EACCES, EIO) and returns{}without logging anything.{}silently) from other errors (log a warning with the actual error before returning{}).[LOW] savedOffsets Held in Memory Forever — Dangling Entries Cause Unnecessary History Searches

Worker 5: Lock File Edge Cases — Audit Complete
Files audited: src/status-watcher.js, src/watcher-manager.js, src/session-monitor.js
[CRITICAL] Gateway crash before any JSONL write — session hangs indefinitely
File: status-watcher.js (~line 84, ~line 107)
The idle timer (idleTimer) is ONLY armed from inside _readFile (via _scheduleIdleCheck). If the gateway crashes immediately after creating the .jsonl.lock file but before writing any JSONL, _readFile is never called, _scheduleIdleCheck is never called, and the session sits in activeBoxes as "active" forever. The 500ms _filePollTimer keeps polling and finding nothing. After gateway restart, watcher.addSession gets an early return (sessions.has guard) so the stuck state is never replaced.
[CRITICAL] Async race: session-idle handler vs. rapid lock reactivation
File: watcher-manager.js (~line 461 session-idle handler, ~line 232 session-added handler)
The session-idle handler awaits API calls (forceFlush, updatePost). While awaiting, a new user message triggers session-lock -> clearCompleted -> pollNow -> session-added. The session-added handler runs and creates a new Mattermost post (postB), sets activeBoxes[key] = postB. The original session-idle handler then resumes and executes activeBoxes.delete(key), watcher.removeSession(key), and monitor.forgetSession(key) — permanently killing the newly re-added active session. The session goes silent with no further reactivation possible until daemon restart.
Minimal fix: in the session-idle handler, snapshot
const box = activeBoxes.get(sessionKey)at entry, and after all awaits guard withif (activeBoxes.get(sessionKey) !== box) return;.[HIGH] Double reactivation: session-lock + session-reactivate both fire for ghost session, no dedup guard
File: watcher-manager.js (~line 376, ~line 387), session-monitor.js (~line 107 clearCompleted)
When a session completes, removeSession sets a ghost watch. On new user message: (1) .jsonl.lock created fires session-lock; (2) .jsonl appended fires session-reactivate. Both handlers call clearCompleted(key) + pollNow() in the same event loop iteration. clearCompleted deletes _knownSessions[key]. First pollNow sets _knownSessions[key] and calls _onSessionAdded (async). Second clearCompleted deletes _knownSessions[key] again. Second pollNow finds isKnown=false and calls _onSessionAdded again. Result: two concurrent session-added events. The session-added handler has NO guard (no activeBoxes.has check at entry). Two posts may be created; first is orphaned.
Minimal fix: add
if (activeBoxes.has(sessionKey)) return;at the top of the session-added handler (before any async work).[HIGH] Lock file detection absent from poll fallback — Docker bind mounts silently broken
File: status-watcher.js (~line 107 _startFilePoll)
_startFilePoll only checks .jsonl file size growth. It never checks .jsonl.lock existence. On Docker bind mounts where fs.watch inotify does not fire (documented in code comments as a known issue), lock file creation and deletion are completely invisible. Neither session-lock nor session-lock-released ever fires. All session turn boundaries fall back to 60-second idle timeout or cache-ttl record. Fast-idle on lock release is silently non-functional in the primary Docker deployment scenario.
[MEDIUM] Lock file fires before sessions.json is updated — early reactivation signal lost for new sessions
File: watcher-manager.js (~line 394), session-monitor.js (~line 129 findSessionByFile)
Code comment says "Lock file is the earliest signal — it fires BEFORE sessions.json is written." When a new session starts, session-lock-path fires, findSessionByFile re-reads sessions.json and returns null (not written yet). If the session was previously completed (in _completedSessions cooldown), clearCompleted is never called. The 2s monitor poll detects the session but checks updatedAt > completedAt. If the gateway does not update updatedAt on each new turn, the session stays suppressed indefinitely in the completed cooldown.
[MEDIUM] Lock file create+delete coalesced in same fs.watch batch — spurious idle signal
File: status-watcher.js (~line 229)
If the gateway creates and deletes the lock file faster than fs.watch delivers events, inotify coalesces them. _onFileChange runs with lockExists=false (statSync finds nothing) and emits session-lock-released without a prior session-lock. For a known session, triggerIdle is called immediately even though no new JSONL content was processed. Session is marked done with empty content for the turn.
[LOW] triggerIdle for already-removed session — safe (early return at line 510)
File: status-watcher.js (~line 510)
triggerIdle checks this.sessions.get(sessionKey) and returns early if null. Safe.
[LOW] Lock file path resolution via slice(0, -5) — correct for all inputs
File: status-watcher.js (~line 228)
.jsonl.lock always ends exactly with .lock (5 chars). endsWith guard on line 227 ensures this. The slice is correct including for paths containing .lock elsewhere. No issue.
Summary: 2 critical, 2 high, 2 medium, 2 low findings. Full findings written to discoveries/lock-file-edge-cases.md.
Worker 5 audit findings received and logged.
Lock File Edge Cases audit is complete. sol's findings cover 2 critical, 2 high, 2 medium, and 2 low severity issues. Results written to discoveries/lock-file-edge-cases.md.
Key findings summary:
[CRITICAL] Gateway crash before first JSONL write -> session hangs indefinitely (idleTimer never armed)
[CRITICAL] Async race: session-idle handler vs. rapid lock reactivation -> activeBoxes.delete kills re-added session
[HIGH] Double reactivation: session-lock + session-reactivate both fire, no dedup guard -> two concurrent session-added events
[HIGH] Lock file detection absent from poll fallback -> fast-idle on lock release silently non-functional on Docker bind mounts
[MEDIUM] Lock file fires before sessions.json is updated -> early reactivation signal lost for new sessions
[MEDIUM] Lock file create+delete coalesced in same fs.watch batch -> spurious idle signal with no prior session-lock
Minimal fixes proposed for each. No code has been changed -- awaiting Rooh's review and approval before any implementation.
Worker 7 -- Ghost Watch Edge Cases
Audit date: 2026-03-09
Scope: status-watcher.js, watcher-manager.js, session-monitor.js
Mode: Read-only analysis
[CRITICAL] Finding 1: Ghost reactivation is non-retryable -- one-shot only
[CRITICAL] Finding 2: Dead zone on Linux Docker -- no poll timer AND no working fs.watch for ghost sessions
[CRITICAL] Finding 3: Double pollNow from ghost + lock file -- potential double _onSessionAdded (currently safe due to guard)
[MEDIUM] Finding 4: Ghost entries for sessions that never reactivate persist in fileToSession forever
[MEDIUM] Finding 5: Ghost entries survive watcher.stop() -- correctness risk on hot reload
[MEDIUM] Finding 6: completedBoxes in watcher-manager grows unbounded (in-memory, resets on restart)
[LOW] Finding 7: Multiple rapid ghost fires -- second fire silently ignored (correct behavior)
[LOW] Finding 8: Reactivation timing -- _onSessionAdded async failure leaves session stranded in _knownSessions
Critical interaction: On Linux Docker with broken fs.watch -- Path A (lock file) and Path B (ghost watch) are both unreliable. Path C (2s monitor poll) is suppressed by _completedSessions cooldown. The only escape is sessions.json having a newer updatedAt than completedAt timestamp -- which requires the gateway to update sessions.json before the monitor can detect it. If the gateway does not update sessions.json updatedAt on each turn, completed sessions are permanently undetectable without a daemon restart.

Worker 8: Plugin KV Consistency Audit
10 findings across plugin/server/store.go, api.go, plugin.go, websocket.go, src/plugin-client.js, and src/watcher-manager.js.
[CRITICAL] handleUpdateSession Overwrites TokenCount with 0 on Intermediate Updates
[CRITICAL] OnDeactivate Overwrites Final Status for Done/Error Sessions
[CRITICAL] KV Key Length May Exceed Mattermost Limit — Silent SaveSession Failure
[MEDIUM] Active Session Count Race — MaxActiveSessions Bypassable Under Concurrency
[MEDIUM] TOCTOU in ListAllSessions — KVList then KVGet Per Key
[MEDIUM] handleDeleteSession KV Delete Error Silently Ignored — Lingering Active Entry
[MEDIUM] No Idempotency on createSession — Duplicate Posts on Daemon Retry
[LOW] broadcastUpdate — nil Lines Slice Inconsistency
[LOW] sessionCleanupLoop — False Positive Stale Detection on Slow Sessions
[LOW] Daemon Shutdown Does Not Update Plugin KV for Active Sessions
Cross-Cutting Notes
KV error swallowing: Both handleCreateSession (LogWarn only) and handleDeleteSession (_ = discard) silently fail KV operations while returning success to the daemon. Daemon has no signal that KV is in an inconsistent state.
ListAllSessions on every createSession: Full paginated KV scan on every POST /api/v1/sessions for the active-count check. At scale with many accumulated done/expired sessions, this blocks every session creation. Consider an in-memory active count with invalidation.
URL encoding is correctly symmetric: Go net/http auto-decodes r.URL.Path, so TrimPrefix yields the decoded session key. encodeKey() re-encodes for KV lookup. Round-trip is consistent. Note: session keys with literal '/' characters would break path routing but current format uses ':' separators only.

NEW INSTRUCTIONS FROM ROOH - READ BEFORE PROCEEDING
Do NOT fix everything at once. Follow this exact sequence:
BATCH 1 (safe fixes - Go plugin + daemon defensive):
Fix these first, they are isolated and low risk:
BATCH 2 (risky fixes - status-watcher.js + session-monitor.js):
DO NOT touch these until Batch 1 is verified working:
AFTER EACH BATCH:
Start with Batch 1 now. Post BATCH_1_READY when done.

PROJ-038 Debug Audit -- FINAL CONSOLIDATED REPORT
109 total findings across 9 audit areas covering ~4,500 lines of code.
TOP 5 MOST URGENT ISSUES
1. Partial JSONL line buffering (status-watcher.js)
File reads split JSON lines across chunks. Both halves fail to parse and are permanently lost. pendingToolCalls gets stuck, session hangs as "active" forever.
2. Ghost watch dead zone on Linux Docker (status-watcher.js / session-monitor.js)
fs.watch recursive doesn't work on Linux. removeSession clears poll timer. Ghost watch depends on fs.watch. completedSessions cooldown blocks monitor re-detection. Circular dependency = permanent dead zone.
3. No HTTP timeout in status-box.js
_httpRequest has no timeout. Hung connections exhaust the 4-socket pool. Combined with missing Retry-After support, this cascades into circuit breaker trips dropping ALL updates for 30s.
4. Async race: session-idle vs lock reactivation (watcher-manager.js)
Idle handler awaits API calls. During those awaits, lock event triggers reactivation (new session-added). When idle handler resumes, it calls activeBoxes.delete on the newly re-added session.
5. No unhandledRejection/uncaughtException handlers (watcher-manager.js)
Any unhandled async error terminates the process with zero cleanup. All status boxes stuck as "active", PID file not removed.

Audit Area 1: Node.js Source Files (src/*.js)
Read-only analysis — no changes proposed. Findings listed with severity, exact location, reproduction scenario, and proposed fix.
[MEDIUM] Double session-idle emission — status-watcher.js
File:
src/status-watcher.jsLines:
triggerIdle()(L300) and330)_checkIdle()(LProblem: Both
triggerIdle()and_checkIdle()can emitsession-idlefor the same session.triggerIdle()fires when the lock file is deleted. If the file poll (_startFilePoll) then detects new trailing bytes (gateway sometimes appends cache-ttl/usage records AFTER deleting the lock), it calls_readFile→_scheduleIdleCheck. AfteridleTimeoutSseconds,_checkIdlefires and seespendingToolCalls === 0and emits a secondsession-idle. The state machine inwatcher-manager.jshas a box-identity guard (activeBoxes.get(sessionKey) !== box), which catches the second emission only AFTER the first handler completes itsawaitchain. If both handlers run concurrently before either modifiesactiveBoxes, both see the sameboxreference and both proceed past the guard.Reproduction: High-latency plugin API call (>0ms) + file poll reads trailing bytes after lock delete.
Proposed fix: In
triggerIdle(), set a flag on state (state._idleTriggered = true) and check it at the top of_checkIdle(). Alternatively, setstate.status = 'done'intriggerIdle()(already done) and add a guard in_checkIdle():if (state.status === 'done') return;.[MEDIUM] _onSessionAdded unhandled rejection — session-monitor.js
File:
src/session-monitor.jsLine:
_poll()→this._onSessionAdded(entry)(called without.catch())Problem:
_onSessionAddedisasync. It is called fire-and-forget in_poll(). IfresolveChannelFromEntry→_resolveDmChannelthrows (e.g., malformed MM URL, unexpected exception before the innertry/catch), the returned Promise rejects silently. Node.js emits anunhandledRejectionevent, which the global handler inwatcher-manager.jstreats as fatal and shuts down the daemon.Reproduction: Malformed session entry with a
tofield starting withuser:+ MM API throwing before the request is sent (e.g., invalid URL passed tonew URL()).Proposed fix: In
_poll(), wrap the call:[LOW] triggerIdle does not clear _lockPollTimer — status-watcher.js
File:
src/status-watcher.jsLines:
triggerIdle()methodProblem:
triggerIdle()clearsidleTimerand_filePollTimerbut NOT_lockPollTimer. The lock poll timer runs untilremoveSession()is eventually called (which happens asynchronously in thesession-idlehandler after plugin/REST API awaits). During this gap,_lockPollTimerstill fires. The idempotency guards (_lockActive,_lockExists) prevent spurious events in most cases, but the timer consumes resources unnecessarily after idle is declared.Proposed fix: Add
if (state._lockPollTimer) { clearInterval(state._lockPollTimer); state._lockPollTimer = null; }totriggerIdle().[LOW] Ghost fileToSession entries never expire — status-watcher.js
File:
src/status-watcher.jsLines:
removeSession()methodProblem:
removeSession()replaces thefileToSessionentry with a'\x00ghost:'marker. Ghost entries are only removed inwatcher-manager.jswhensession-reactivatefires. If a session completes and the user never sends another message (no lock file created → no reactivation), the ghost entry lives infileToSessionindefinitely. Over long daemon uptime with many completed sessions,fileToSessiongrows without bound.Proposed fix: Add a TTL to ghost entries (e.g., remove ghost after 30 minutes). Could be implemented with a
setTimeoutinremoveSession().[LOW] saveOffsets blocks event loop on every session-update — watcher-manager.js
File:
src/watcher-manager.jsLines:
session-updatehandler →saveOffsets()Problem:
saveOffsets()usesfs.writeFileSync(), which blocks the event loop. It is called on EVERYsession-updateevent, which fires on every file read (up to every 500ms per active session). With 10 active sessions, this is up to 20 synchronous disk writes per second.Proposed fix: Debounce
saveOffsetsso it fires at most once every 5-10 seconds. The 30s interval already exists — remove the inline call fromsession-updateand rely on that interval plus the explicit call insession-idleand shutdown.[LOW] findExistingPost trips circuit breaker — watcher-manager.js
File:
src/watcher-manager.jsLines:
findExistingPost()→statusBox._apiCallWithRetry()Problem:
findExistingPostcalls the privatestatusBox._apiCallWithRetry()method directly for post search. This routes through the circuit breaker. A failed search (e.g., Mattermost search index unavailable) increments the failure counter and can trip the circuit breaker, blocking all subsequent status updates for 30 seconds. Post search is non-critical (restart recovery only).Proposed fix: Call
statusBox._httpRequest()directly for search (bypassing circuit breaker), or wrap in a try/catch that silently returns null on any error without routing through the breaker.[LOW] pendingSubAgents grows for orphaned parents — watcher-manager.js
File:
src/watcher-manager.jsLines:
session-addedhandler — sub-agent queuingProblem: Sub-agents arriving before their parent are queued in
pendingSubAgents. If the parent session is a non-MM session (skipped due to no channel), or is removed before appearing as an active box, the sub-agent info is never dequeued and accumulates indefinitely.Proposed fix: Cap queue size per parent key (e.g., max 10 pending sub-agents), or evict pending entries after 5 minutes.
[LOW] No numeric range validation in config — config.js
File:
src/config.jsProblem:
IDLE_TIMEOUT_S=0,SESSION_POLL_MS=0,MAX_ACTIVE_SESSIONS=0are accepted without validation. A zero poll interval creates a tightsetIntervalloop, saturating the CPU. Zero idle timeout fires idle checks immediately on every file read.Proposed fix: Add minimum value guards in
buildConfig():Audit Area 2: Go Plugin Server + Plugin Webapp
[MEDIUM] children_json vs children field mismatch — websocket.go / index.tsx
File:
plugin/server/websocket.go+plugin/webapp/src/index.tsxLines:
broadcastUpdate()payload;index.tsxWebSocket handlerProblem:
broadcastUpdateserializes child sessions as a JSON-encoded string under the key"children_json":But the TypeScript WebSocket handler reads
data.children(an array):The webapp never parses
children_json. Sub-agent sessions are silently dropped — they are never displayed inLiveStatusPost,FloatingWidget, orRHSPanel. The plugin KV store has children as[]SessionData(correctly typed), but the WebSocket path loses them.Reproduction: Any session with active sub-agents in plugin mode — children never appear in the floating widget or live status post.
Proposed fix (no functional change until approved): In the WebSocket handler (
index.tsx), add:And use
childreninstead ofdata.children || [].[LOW] KVList pagination race — store.go
File:
plugin/server/store.goLines:
ListAllSessions()method, page loopProblem:
KVListuses offset-based pagination (page,perPage). Between page 0 and page 1, a concurrentKVSet(new session created) shifts all keys by one position. Keys can appear twice or be skipped entirely in a singleListAllSessionscall. This affectsCleanStaleSessions(could clean a session twice — idempotent so harmless) andhandleCreateSession(active count may be off by 1 during concurrent session creation, allowing brief overflow ofMaxActiveSessions).Proposed fix: Accept as a known limitation (offset pagination has no atomic snapshot). Document it. No fix needed unless Mattermost exposes a consistent KV list API.
[LOW] CleanStaleSessions silently discards write errors — store.go
File:
plugin/server/store.goLines:
CleanStaleSessions(),_ = s.SaveSession(...)and_ = s.DeleteSession(...)Problem: If KV write fails during cleanup (e.g., Mattermost KV store temporarily unavailable), errors are silently discarded. The
cleanedandexpiredcounters increment even though the write failed. The caller (sessionCleanupLoop) logs success with stale counts. Stale sessions survive when they should have been cleaned.Proposed fix: Collect errors and log them individually. Return accumulated errors. Minor — cleanup is best-effort, but logging helps diagnose persistent KV issues.
[LOW] handleDeleteSession — broadcastUpdate before KV delete — api.go
File:
plugin/server/api.goLines:
handleDeleteSession()— ordering of broadcastUpdate vs DeleteSessionProblem:
broadcastUpdatefires the WebSocket event (status=done) beforeDeleteSessionremoves the KV entry. A client receiving the WebSocket event and immediately callingGET /api/v1/sessionswill see the session in "active" state (KV not yet deleted), then "done" after a race. This window is minimal but theoretically observable. More critically: if the plugin crashes between broadcast and delete, the session remains in KV with status="active" permanently (until the 30-minute stale cleanup cycle).Proposed fix: Reorder: delete from KV first, then broadcast. If KV delete fails, return an error without broadcasting.
[LOW] updatePostMessageForMobile called from goroutine without WaitGroup — api.go
File:
plugin/server/api.goLines:
handleUpdateSession()→go p.updatePostMessageForMobile(*existing)Problem:
updatePostMessageForMobileis launched as a fire-and-forget goroutine. On plugin deactivation (OnDeactivate), goroutines that are mid-API-call are killed without waiting for completion. The Mattermost API call inside could be interrupted, leaving the post message in an inconsistent state. During rapid session updates, multiple concurrentupdatePostMessageForMobilegoroutines for the same post can race each other.Proposed fix: Use a semaphore or debounce (only fire if message content actually changed — the
post.Message == newMessageguard helps but doesn't prevent concurrent goroutines). Add aWaitGroupin the Plugin struct, increment on launch, decrement on completion, andWait()inOnDeactivate.[LOW] FloatingWidget drag not clamped to viewport — floating_widget.tsx
File:
plugin/webapp/src/components/floating_widget.tsxLines:
onMouseMovedrag handlerProblem: Widget position is clamped to
Math.max(0, ...)preventing negative offsets, but not to maximum values.position.rightcan exceed the viewport width andposition.bottomcan exceed the viewport height, effectively dragging the widget off-screen with no way to recover (except clearing localStorage).Proposed fix: Clamp to viewport:
[LOW] FloatingWidget polling interval fires when not visible — floating_widget.tsx
File:
plugin/webapp/src/components/floating_widget.tsxLines:
useEffectwith 2ssetIntervalpolling fallbackProblem: A 2-second polling interval runs unconditionally regardless of widget visibility or active session state. The
setSessionscallback does a key-by-key comparison to avoid unnecessary state updates, so React won't re-render. However, the interval itself (and the comparison logic) executes continuously even when there are no sessions and the widget is hidden.Proposed fix: Pause polling when
!visibleorObject.keys(sessions).length === 0. Low priority — the setState comparison prevents re-renders, so the impact is minimal.[LOW] ChildSession elapsed time does not update — live_status_post.tsx
File:
plugin/webapp/src/components/live_status_post.tsxLines:
ChildSessioncomponentProblem:
ChildSessionrendersformatElapsed(child.elapsed_ms)wherechild.elapsed_msis the value from the last WebSocket update. For active child sessions, the elapsed timer is frozen at the last push interval (not a live counter). Only the parent session has a live elapsed clock viasetInterval.Reproduction: Active sub-agent session — elapsed time shown in child block doesn't tick.
Proposed fix: Add a
useEffectwith 1s interval inChildSessionwhenchild.status === 'active', similar to the parent component's implementation.[LOW] start-daemon.sh graceful shutdown window too short — start-daemon.sh
File:
start-daemon.shLines: Kill + sleep 1 block
Problem: When restarting, the script kills the old daemon and waits only 1 second before removing the PID file and starting a new instance.
shutdown()inwatcher-manager.jscallssharedStatusBox.flushAll()which awaits all pending HTTP calls. With 20 active sessions and Mattermost responding slowly (e.g., 800ms per PUT), 1 second is not enough for graceful flush, leaving some status boxes in mid-update state.Proposed fix: Send SIGTERM and wait for the PID file to disappear (up to 10s timeout) instead of a fixed
