From 1f83a7d7c43d61425272c4c174e3a3b35f0eae68 Mon Sep 17 00:00:00 2001 From: mindesbunister Date: Mon, 1 Dec 2025 11:49:23 +0100 Subject: [PATCH] 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. --- .github/prompts/general prompt.prompt.md | 6 +- CLUSTER_STOP_BUTTON_FIX_COMPLETE.md | 662 ++++++++++++++++++ app/cluster/page.tsx | 48 +- .../v9_chunk_000002_spec.json | 47 +- cluster/exploration.db | Bin 40960 -> 40960 bytes 5 files changed, 727 insertions(+), 36 deletions(-) create mode 100644 CLUSTER_STOP_BUTTON_FIX_COMPLETE.md diff --git a/.github/prompts/general prompt.prompt.md b/.github/prompts/general prompt.prompt.md index 8f90d35..eeee8cd 100644 --- a/.github/prompts/general prompt.prompt.md +++ b/.github/prompts/general prompt.prompt.md @@ -5,14 +5,14 @@ You are working on Trading Bot v4, a real money algorithmic trading system manag MANDATORY FIRST STEPS: -1.

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.

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(`πŸ—‘οΈ Removing ${lockFiles.length} stale lock files`) + lockFiles.forEach(f => fs.unlinkSync(path.join(clusterDir, f))) +} +``` + +--- + +### 3.
