From 4600aa6598bcb78f6e6bfbf4b8838bf26a90f9fd Mon Sep 17 00:00:00 2001 From: jedarden Date: Thu, 25 Jun 2026 14:30:14 -0400 Subject: [PATCH] fix(bf-2w7): improve cleanup robustness and orphan detection - Lower orphan cleanup threshold from 10 minutes to 60 seconds for faster cleanup - Add debug logging to orphan cleanup (warn on errors, info on success) - Improve FIFO removal with explicit retry loop (3 attempts, 5ms delays) - Apply same robust FIFO removal logic to both cleanup paths The cleanup implementation now: - Removes orphans within 1 minute instead of 10 minutes - Logs cleanup operations for debugging - Retries FIFO removal to handle transient file system errors - Ensures FIFO is removed before directory removal in all cases All 90 tests pass with these improvements.
