feat: Add coordinator log viewer to cluster UI
- Created /api/cluster/logs endpoint to read coordinator.log - Added real-time log display in cluster UI (updates every 3s) - Shows last 100 lines of coordinator.log in terminal-style display - Includes manual refresh button - Improves debugging experience - no need to SSH for logs User feedback: 'why dont we add the output of the log at the bottom of the page so i know whats going on' This addresses poor visibility into coordinator errors and failures. Next step: Fix SSH timeout issue blocking worker execution.

|
||||||
|
|
||||||
|
**Date:** December 1, 2025
|
||||||
|
**Status:** ✅ DEPLOYED AND VERIFIED
|
||||||

## Executive Summary
|
||||||
|
|
||||||
|
Successfully fixed two critical cluster management issues:
|
||||||
|
1. **Stop button database reset** - Now works even when coordinator crashed
|
||||||
|
2. **Stale metrics display** - UI now shows accurate 4-state system
|
||||||
|
|
||||||
|
**Key Achievement:** Database-first architecture ensures clean cluster state regardless of process crashes.

## Issues Resolved
|
||||||
|
|
||||||
|
### Issue #1: Stop Button Appears Broken
|
||||||
|
|
||||||
|
**Original Problem:**
|
||||||
|
- User clicks Stop button
|
||||||
|
- Button appears to fail (shows error in UI)
|
||||||
|
- Database still shows chunks as "running"
|
||||||
|
- Can't restart cluster cleanly
|
||||||
|
|
||||||
|
**Root Cause:**
|
||||||
|
- Database already in stale state BEFORE Stop clicked
|
||||||
|
- Old logic: pkill processes → wait → reset database
|
||||||
|
- If coordinator crashed earlier, database never got reset
|
||||||
|
- Stop button tried to reset but stale data made it look failed
|
||||||
|
|
||||||
|
**Fix Applied:**
|
||||||
|
```typescript
|
||||||
|
// NEW ORDER: Database reset FIRST, then pkill
|
||||||
|
if (action === 'stop') {
|
||||||
|
// 1. Reset database state FIRST (even if coordinator already gone)
|
||||||
|
const db = await open({ filename: dbPath, driver: sqlite3.Database })
|
||||||
|
await db.run(`UPDATE chunks SET status='pending', assigned_worker=NULL, started_at=NULL WHERE status='running'`)
|
||||||
|
const pendingCount = await db.get(`SELECT COUNT(*) as count FROM chunks WHERE status='pending'`)
|
||||||
|
await db.close()
|
||||||
|
|
||||||
|
// 2. THEN try to stop any running processes
|
||||||
|
const stopCmd = 'pkill -9 -f distributed_coordinator; pkill -9 -f distributed_worker'
|
||||||
|
try {
|
||||||
|
await execAsync(stopCmd)
|
||||||
|
} catch (err) {
|
||||||
|
console.log('📝 No processes to kill (already stopped)')
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Verification:**
|
||||||
|
```bash
|
||||||
|
# Before fix:
|
||||||
|
curl POST /api/cluster/control '{"action":"stop"}'
|
||||||
|
# → {"success": false, "error": "sqlite3: not found"}
|
||||||
|
|
||||||
|
# After fix:
|
||||||
|
curl POST /api/cluster/control '{"action":"stop"}'
|
||||||
|
# → {"success": true, "message": "Cluster stopped and database reset to pending"}
|
||||||
|
|
||||||
|
# Database state:
|
||||||
|
sqlite3 exploration.db "SELECT status, COUNT(*) FROM chunks GROUP BY status;"
|
||||||
|
# Before: running|3
|
||||||
|
# After: pending|3 ✅
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### Issue #2: Stale Metrics Display
|
||||||
|
|
||||||
|
**Original Problem:**
|
||||||
|
- UI shows "ACTIVE" status with 3 running chunks
|
||||||
|
- Progress bar shows 0.00% (no actual work happening)
|
||||||
|
- Confusing state: looks active but nothing running
|
||||||
|
- Missing "Idle" state when no work queued
|
||||||
|
|
||||||
|
**Root Cause:**
|
||||||
|
- Coordinator crashed without updating database
|
||||||
|
- Status API trusts database without verification
|
||||||
|
- UI only showed 3 states (Processing/Pending/Complete)
|
||||||
|
- No visual indicator for "no work at all" state
|
||||||
|
|
||||||
|
**Fix Applied:**
|
||||||
|
```typescript
|
||||||
|
// UI Enhancement - 4-state display system
|
||||||
|
{status.exploration.chunks.running > 0 ? (
|
||||||
|
<span className="text-yellow-400">⚡ Processing</span>
|
||||||
|
) : status.exploration.chunks.pending > 0 ? (
|
||||||
|
<span className="text-blue-400">⏳ Pending</span>
|
||||||
|
) : status.exploration.chunks.completed === status.exploration.chunks.total ? (
|
||||||
|
<span className="text-green-400">✅ Complete</span>
|
||||||
|
) : (
|
||||||
|
<span className="text-gray-400">⏸️ Idle</span> // NEW STATE
|
||||||
|
)}
|
||||||
|
|
||||||
|
// Show pending chunk count
|
||||||
|
{status.exploration.chunks.pending > 0 && (
|
||||||
|
<span className="text-gray-400">({status.exploration.chunks.pending} pending)</span>
|
||||||
|
)}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Verification:**
|
||||||
|
```bash
|
||||||
|
curl -s http://localhost:3001/api/cluster/status | jq '.exploration'
|
||||||
|
# After Stop button:
|
||||||
|
{
|
||||||
|
"totalCombinations": 4096,
|
||||||
|
"testedCombinations": 0,
|
||||||
|
"progress": 0,
|
||||||
|
"chunks": {
|
||||||
|
"total": 3,
|
||||||
|
"completed": 0,
|
||||||
|
"running": 0, # ✅ Was 3 before fix
|
||||||
|
"pending": 3 # ✅ Correctly reset
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## Technical Implementation
|
||||||
|
|
||||||
|
### Database Operations Refactor
|
||||||
|
|
||||||
|
**Problem:** Original code used sqlite3 CLI commands
|
||||||
|
```typescript
|
||||||
|
// ❌ DOESN'T WORK IN DOCKER
|
||||||
|
const resetCmd = `sqlite3 ${dbPath} "UPDATE chunks SET status='pending'..."`
|
||||||
|
await execAsync(resetCmd)
|
||||||
|
// Error: /bin/sh: sqlite3: not found
|
||||||
|
```
|
||||||
|
|
||||||
|
**Solution:** Use Node.js sqlite library
|
||||||
|
```typescript
|
||||||
|
// ✅ WORKS IN DOCKER
|
||||||
|
const db = await open({
|
||||||
|
filename: dbPath,
|
||||||
|
driver: sqlite3.Database
|
||||||
|
})
|
||||||
|
await db.run(`UPDATE chunks SET status=?, assigned_worker=NULL WHERE status=?`,
|
||||||
|
['pending', 'running'])
|
||||||
|
const result = await db.get(`SELECT COUNT(*) as count FROM chunks WHERE status=?`,
|
||||||
|
['pending'])
|
||||||
|
await db.close()
|
||||||
|
```
|
||||||
|
|
||||||
|
**Why This Matters:**
|
||||||
|
- Docker container uses node:20-alpine (minimal Linux)
|
||||||
|
- Alpine doesn't include sqlite3 CLI by default
|
||||||
|
- Node.js sqlite3 library already installed (used in status API)
|
||||||
|
- Cleaner code, better error handling, no shell dependencies
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### File Permissions Fix
|
||||||
|
|
||||||
|
**Problem:** Database readonly in container
|
||||||
|
```
|
||||||
|
SQLITE_READONLY: attempt to write a readonly database
|
||||||
|
```
|
||||||
|
|
||||||
|
**Root Cause:**
|
||||||
|
- Database file owned by root (UID 0)
|
||||||
|
- Container runs as nextjs user (UID 1001)
|
||||||
|
- SQLite needs write access + directory write for lock files
|
||||||
|
|
||||||
|
**Solution:**
|
||||||
|
```bash
|
||||||
|
# Fix database file ownership
|
||||||
|
chown 1001:1001 /home/icke/traderv4/cluster/exploration.db
|
||||||
|
chmod 664 /home/icke/traderv4/cluster/exploration.db
|
||||||
|
|
||||||
|
# Fix directory permissions (for lock files)
|
||||||
|
chown 1001:1001 /home/icke/traderv4/cluster
|
||||||
|
chmod 775 /home/icke/traderv4/cluster
|
||||||
|
|
||||||
|
# Verification:
|
||||||
|
ls -la /home/icke/traderv4/cluster/
|
||||||
|
drwxrwxr-x 4 1001 1001 30 Dec 1 10:02 .
|
||||||
|
-rw-rw-r-- 1 1001 1001 40960 Dec 1 10:02 exploration.db
|
||||||
|
```

||||||

## Deployment Process
|
||||||
|
|
||||||
|
### Build & Deploy Steps
|
||||||
|
|
||||||
|
1. **Code Changes:**
|
||||||
|
- Updated control/route.ts with database-first logic
|
||||||
|
- Enhanced page.tsx with 4-state display
|
||||||
|
- Replaced sqlite3 CLI with Node.js API
|
||||||
|
|
||||||
|
2. **Docker Build:**
|
||||||
|
```bash
|
||||||
|
docker compose build trading-bot
|
||||||
|
# Build time: ~73 seconds
|
||||||
|
# Image: sha256:7b830abb...
|
||||||
|
```
|
||||||
|
|
||||||
|
3. **Container Restart:**
|
||||||
|
```bash
|
||||||
|
docker compose up -d --force-recreate trading-bot
|
||||||
|
# Container: trading-bot-v4 started successfully
|
||||||
|
```
|
||||||
|
|
||||||
|
4. **Permission Fix:**
|
||||||
|
```bash
|
||||||
|
chown 1001:1001 /home/icke/traderv4/cluster/exploration.db
|
||||||
|
chmod 664 /home/icke/traderv4/cluster/exploration.db
|
||||||
|
chown 1001:1001 /home/icke/traderv4/cluster
|
||||||
|
chmod 775 /home/icke/traderv4/cluster
|
||||||
|
```
|
||||||
|
|
||||||
|
5. **Testing:**
|
||||||
|
```bash
|
||||||
|
# Test Stop button
|
||||||
|
curl -X POST http://localhost:3001/api/cluster/control \
|
||||||
|
-H "Content-Type: application/json" \
|
||||||
|
-d '{"action":"stop"}' | jq .
|
||||||
|
|
||||||
|
# Result: {"success": true, "message": "Cluster stopped..."}
|
||||||
|
```
|
||||||
|
|
||||||
|
6. **Verification:**
|
||||||
|
```bash
|
||||||
|
# Check database state
|
||||||
|
sqlite3 exploration.db "SELECT status, COUNT(*) FROM chunks GROUP BY status;"
|
||||||
|
# Result: pending|3 ✅
|
||||||
|
|
||||||
|
# Check status API
|
||||||
|
curl -s http://localhost:3001/api/cluster/status | jq .exploration
|
||||||
|
# Result: running=0, pending=3, progress=0% ✅
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Container Logs
|
||||||
|
|
||||||
|
**Stop Button Operation (Successful):**
|
||||||
|
```
|
||||||
|
🛑 Stopping cluster...
|
||||||
|
🔧 Resetting database chunks to pending...
|
||||||
|
✅ Database cleanup complete - 3 chunks reset to pending (total pending: 3)
|
||||||
|
📝 No processes to kill (already stopped)
|
||||||
|
```
|
||||||
|
|
||||||
|
**Key Log Messages:**
|
||||||
|
- `🔧 Resetting database chunks to pending...` - Database operation started
|
||||||
|
- `✅ Database cleanup complete - 3 chunks reset` - Success confirmation
|
||||||
|
- Shows count of chunks reset and total pending
|
||||||
|
- Gracefully handles "no processes to kill" (already crashed scenario)

## Testing Results
|
||||||
|
|
||||||
|
### Test Case: Stale Database from Coordinator Crash
|
||||||
|
|
||||||
|
**Initial State:**
|
||||||
|
```sql
|
||||||
|
SELECT status, COUNT(*) FROM chunks GROUP BY status;
|
||||||
|
-- Result: running|3
|
||||||
|
```
|
||||||
|
|
||||||
|
**Stop Button Action:**
|
||||||
|
```bash
|
||||||
|
curl -X POST http://localhost:3001/api/cluster/control \
|
||||||
|
-H "Content-Type: application/json" \
|
||||||
|
-d '{"action":"stop"}' | jq .
|
||||||
|
```
|
||||||
|
|
||||||
|
**Response:**
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"success": true,
|
||||||
|
"message": "Cluster stopped and database reset to pending",
|
||||||
|
"isRunning": false,
|
||||||
|
"note": "All processes stopped, chunks reset"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Final State:**
|
||||||
|
```sql
|
||||||
|
SELECT status, COUNT(*) FROM chunks GROUP BY status;
|
||||||
|
-- Result: pending|3 ✅
|
||||||
|
```
|
||||||
|
|
||||||
|
**Status API After Stop:**
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"totalCombinations": 4096,
|
||||||
|
"testedCombinations": 0,
|
||||||
|
"progress": 0,
|
||||||
|
"chunks": {
|
||||||
|
"total": 3,
|
||||||
|
"completed": 0,
|
||||||
|
"running": 0, // Was 3 before
|
||||||
|
"pending": 3 // Correctly reset
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## Architecture Decision: Database-First
|
||||||
|
|
||||||
|
### Why Database Reset Comes First
|
||||||
|
|
||||||
|
**Old Approach (WRONG):**
|
||||||
|
```
|
||||||
|
Stop Button → pkill processes → wait → reset database
|
||||||
|
Problem: If processes already crashed, database never resets
|
||||||
|
```
|
||||||
|
|
||||||
|
**New Approach (CORRECT):**
|
||||||
|
```
|
||||||
|
Stop Button → reset database → pkill processes → verify
|
||||||
|
Benefit: Database always clean regardless of process state
|
||||||
|
```
|
||||||
|
|
||||||
|
**Rationale:**
|
||||||
|
1. **Idempotency:** Database reset safe to run multiple times
|
||||||
|
2. **Crash Recovery:** Works even when coordinator already dead
|
||||||
|
3. **User Intent:** "Stop" means "clean up everything" not just "kill processes"
|
||||||
|
4. **Restart Readiness:** Fresh database state enables immediate restart
|
||||||
|
5. **Error Isolation:** Process kill failure doesn't block database cleanup
|
||||||
|
|
||||||
|
**Real-World Scenario:**
|
||||||
|
- Coordinator crashes at 2 AM (out of memory, network issue, etc.)
|
||||||
|
- Database left with 3 chunks in "running" state
|
||||||
|
- User wakes up at 9 AM, sees stale "ACTIVE" status
|
||||||
|
- Clicks Stop button
|
||||||
|
- OLD: Would fail because processes already gone
|
||||||
|
- NEW: Succeeds because database reset happens first ✅
|
||||||

## Files Changed
|
||||||
|
|
||||||
|
### app/api/cluster/control/route.ts (Major Refactor)
|
||||||
|
|
||||||
|
**Before:**
|
||||||
|
```typescript
|
||||||
|
// Start action - shell command (doesn't work in Docker)
|
||||||
|
const resetCmd = `sqlite3 ${dbPath} "UPDATE chunks..."`
|
||||||
|
await execAsync(resetCmd)
|
||||||
|
|
||||||
|
// Stop action - pkill first, database second
|
||||||
|
const stopCmd = 'pkill -9 -f distributed_coordinator'
|
||||||
|
await execAsync(stopCmd)
|
||||||
|
// ... then reset database
|
||||||
|
```
|
||||||
|
|
||||||
|
**After:**
|
||||||
|
```typescript
|
||||||
|
// Imports added:
|
||||||
|
import sqlite3 from 'sqlite3'
|
||||||
|
import { open } from 'sqlite'
|
||||||
|
|
||||||
|
// Start action - Node.js API
|
||||||
|
const db = await open({ filename: dbPath, driver: sqlite3.Database })
|
||||||
|
await db.run(`UPDATE chunks SET status='pending', assigned_worker=NULL, started_at=NULL WHERE status='running'`)
|
||||||
|
await db.close()
|
||||||
|
|
||||||
|
// Stop action - DATABASE FIRST
|
||||||
|
// 1. Reset database state
|
||||||
|
const db = await open({ filename: dbPath, driver: sqlite3.Database })
|
||||||
|
const result = await db.run(`UPDATE chunks SET status='pending'...`)
|
||||||
|
const pendingCount = await db.get(`SELECT COUNT(*) as count FROM chunks WHERE status='pending'`)
|
||||||
|
await db.close()
|
||||||
|
|
||||||
|
// 2. THEN kill processes
|
||||||
|
const stopCmd = 'pkill -9 -f distributed_coordinator; pkill -9 -f distributed_worker'
|
||||||
|
try {
|
||||||
|
await execAsync(stopCmd)
|
||||||
|
} catch (err) {
|
||||||
|
console.log('📝 No processes to kill (already stopped)')
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Changes:**
|
||||||
|
- Added sqlite3/sqlite imports (lines 5-6)
|
||||||
|
- Replaced 3 sqlite3 CLI calls with Node.js API
|
||||||
|
- Reordered stop logic (database first, pkill second)
|
||||||
|
- Enhanced error handling and logging
|
||||||
|
- Added count verification for reset chunks
|
||||||
|
|
||||||

### app/cluster/page.tsx (UI Enhancement)
|
||||||
|
|
||||||
|
**Before:**
|
||||||
|
```typescript
|
||||||
|
// Only 3 states
|
||||||
|
{status.exploration.chunks.running > 0 ? (
|
||||||
|
<span>⚡ Processing</span>
|
||||||
|
) : status.exploration.chunks.pending > 0 ? (
|
||||||
|
<span>⏳ Pending</span>
|
||||||
|
) : (
|
||||||
|
<span>✅ Complete</span>
|
||||||
|
)}
|
||||||
|
```
|
||||||
|
|
||||||
|
**After:**
|
||||||
|
```typescript
|
||||||
|
// 4 states + pending count display
|
||||||
|
{status.exploration.chunks.running > 0 ? (
|
||||||
|
<span className="text-yellow-400">⚡ Processing</span>
|
||||||
|
) : status.exploration.chunks.pending > 0 ? (
|
||||||
|
<span className="text-blue-400">⏳ Pending</span>
|
||||||
|
) : status.exploration.chunks.completed === status.exploration.chunks.total &&
|
||||||
|
status.exploration.chunks.total > 0 ? (
|
||||||
|
<span className="text-green-400">✅ Complete</span>
|
||||||
|
) : (
|
||||||
|
<span className="text-gray-400">⏸️ Idle</span> // NEW
|
||||||
|
)}
|
||||||
|
|
||||||
|
// Show pending count when present
|
||||||
|
{status.exploration.chunks.pending > 0 && status.exploration.chunks.running === 0 && (
|
||||||
|
<span className="text-gray-400 ml-2">({status.exploration.chunks.pending} pending)</span>
|
||||||
|
)}
|
||||||
|
```
|
||||||
|
|
||||||
|
**Changes:**
|
||||||
|
- Added 4th state: "⏸️ Idle" (no work queued)
|
||||||
|
- Shows pending chunk count when work queued but not running
|
||||||
|
- Better color coding (yellow/blue/green/gray)
|
||||||
|
- More precise state logic (checks total > 0 for Complete)

## Lessons Learned
|
||||||
|
|
||||||
|
### 1. Docker Environment Constraints
|
||||||
|
|
||||||
|
**Discovery:** Shell commands that work on host may not exist in Docker container
|
||||||
|
|
||||||
|
**Example:**
|
||||||
|
- Host: sqlite3 CLI installed system-wide
|
||||||
|
- Container: node:20-alpine minimal image (no sqlite3)
|
||||||
|
- Solution: Use native libraries already in node_modules
|
||||||
|
|
||||||
|
**Takeaway:** Always test in target environment (container), not just on host
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 2. Database-First Architecture
|
||||||
|
|
||||||
|
**Principle:** Critical state cleanup should happen BEFORE process management
|
||||||
|
|
||||||
|
**Example:**
|
||||||
|
- OLD: Kill processes → reset database (fails if processes already dead)
|
||||||
|
- NEW: Reset database → kill processes (always works)
|
||||||
|
|
||||||
|
**Takeaway:** State cleanup operations should be idempotent and order matters
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 3. Container User Permissions
|
||||||
|
|
||||||
|
**Discovery:** Container runs as UID 1001 (nextjs), not root
|
||||||
|
|
||||||
|
**Impact:**
|
||||||
|
- Files created by root (UID 0) are readonly to container
|
||||||
|
- SQLite needs write access to both file AND directory (for lock files)
|
||||||
|
- Permission 644 not enough, need 664 (group write)
|
||||||
|
|
||||||
|
**Solution:**
|
||||||
|
```bash
|
||||||
|
chown 1001:1001 cluster/exploration.db # Match container user
|
||||||
|
chmod 664 cluster/exploration.db # Group write
|
||||||
|
chown 1001:1001 cluster/ # Directory ownership
|
||||||
|
chmod 775 cluster/ # Directory write for locks
|
||||||
|
```
|
||||||
|
|
||||||
|
**Takeaway:** Always match host file permissions to container user UID
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 4. Comprehensive Logging
|
||||||
|
|
||||||
|
**Before:** Simple success/failure messages
|
||||||
|
|
||||||
|
**After:** Detailed operation flow with counts
|
||||||
|
```typescript
|
||||||
|
console.log('🔧 Resetting database chunks to pending...')
|
||||||
|
console.log(`✅ Database cleanup complete - ${result.changes} chunks reset to pending (total pending: ${pendingCount?.count})`)
|
||||||
|
console.log('📝 No processes to kill (already stopped)')
|
||||||
|
```
|
||||||
|
|
||||||
|
**Benefits:**
|
||||||
|
- User sees exactly what happened
|
||||||
|
- Debugging issues easier (know which step failed)
|
||||||
|
- Confirms operation success with verification counts
|
||||||
|
- Distinguishes between "no processes found" vs "kill failed"
|
||||||
|
|
||||||
|
**Takeaway:** Verbose logging in infrastructure operations pays off during troubleshooting
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## Future Enhancements
|
||||||
|
|
||||||
|
### 1. Automatic Permission Handling
|
||||||
|
|
||||||
|
**Current:** Manual chown/chmod required for database
|
||||||
|
|
||||||
|
**Proposed:** Docker entrypoint script that fixes permissions on startup
|
||||||
|
```bash
|
||||||
|
#!/bin/sh
|
||||||
|
# Fix cluster directory permissions
|
||||||
|
chown -R nextjs:nodejs /app/cluster
|
||||||
|
chmod -R u+rw,g+rw /app/cluster
|
||||||
|
exec "$@"
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 2. Database Lock File Cleanup
|
||||||
|
|
||||||
|
**Current:** SQLite may leave lock files on crash
|
||||||
|
|
||||||
|
**Proposed:** Check for stale lock files on Stop
|
||||||
|
```typescript
|
||||||
|
// In stop action:
|
||||||
|
const lockFiles = fs.readdirSync(clusterDir).filter(f => f.includes('.db-'))
|
||||||
|
if (lockFiles.length > 0) {
|
||||||
|
console.log(`🗑️ Removing ${lockFiles.length} stale lock files`)
|
||||||
|
lockFiles.forEach(f => fs.unlinkSync(path.join(clusterDir, f)))
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 3. Status API Health Checks
|
||||||
|
|
||||||
|
**Current:** Status API trusts database without verification
|
||||||
|
|
||||||
|
**Proposed:** Cross-check process existence
|
||||||
|
```typescript
|
||||||
|
// In status API:
|
||||||
|
if (runningChunks > 0) {
|
||||||
|
const psOutput = await execAsync('ps aux | grep -c "[d]istributed_coordinator"')
|
||||||
|
const processCount = parseInt(psOutput.stdout)
|
||||||
|
if (processCount === 0) {
|
||||||
|
console.warn('⚠️ Database shows running chunks but no coordinator process!')
|
||||||
|
// Auto-fix: Reset database to pending
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|

## Summary
|
||||||
|
|
||||||
|
### What We Fixed
|
||||||
|
|
||||||
|
1. **Stop Button Database Reset**
|
||||||
|
- Reordered logic: database cleanup FIRST, process kill second
|
||||||
|
- Replaced sqlite3 CLI with Node.js API (Docker compatible)
|
||||||
|
- Fixed file permissions for container write access
|
||||||
|
- Added comprehensive logging and error handling
|
||||||
|
|
||||||
|
2. **Stale Metrics Display**
|
||||||
|
- Added 4th UI state: "⏸️ Idle" (no work queued)
|
||||||
|
- Show pending chunk count when work queued
|
||||||
|
- Better visual differentiation (colors, emojis)
|
||||||
|
- Accurate state after Stop button operation
|
||||||
|
|
||||||
|
### Why It Matters
|
||||||
|
|
||||||
|
**User Impact:**
|
||||||
|
- Can now confidently restart cluster after crashes
|
||||||
|

|
||||||
|
- No confusion from stale "ACTIVE" displays
|
||||||
|
- Reliable cleanup operation
|
||||||
|
|
||||||
|
**Technical Impact:**
|
||||||
|
- Database-first architecture prevents state corruption
|
||||||
|

|
||||||
|
- Proper error handling and verification
|
||||||
|
- Comprehensive logging for debugging
|
||||||
|
|
||||||
|
**Research Impact:**
|
