From 64cce2bf1013d285a703ec4990073f4a84ee5609 Mon Sep 17 00:00:00 2001 From: Alessandro Costa Date: Sat, 4 Apr 2026 19:15:08 -0300 Subject: [PATCH] fix: resolve 3 upstream bugs (summarize, ChromaSync, HealthMonitor) (#1566) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit * fix: resolve 3 upstream bugs in summarize, ChromaSync, and HealthMonitor 1. summarize.ts: Skip summary when transcript has no assistant message. Prevents error loop where empty transcripts cause repeated failed summarize attempts (~30 errors/day observed in production). 2. ChromaSync.ts: Fallback to chroma_update_documents when add fails with "IDs already exist". Handles partial writes after MCP timeout without waiting for next backfill cycle. 3. HealthMonitor.ts: Replace HTTP-based isPortInUse with atomic socket bind on Unix. Eliminates TOCTOU race when two sessions start simultaneously (HTTP check is non-atomic — both see "port free" before either completes listen()). Updated tests accordingly. All three bugs are pre-existing in v10.5.5. Confirmed via log analysis of 543K lines over 17 days of production usage across two servers.
