From 2c7b551c7959edae1edbd1cd57a46b0423d2a38e Mon Sep 17 00:00:00 2001 From: "google-labs-jules[bot]" <161369871+google-labs-jules[bot]@users.noreply.github.com> Date: Tue, 24 Feb 2026 04:15:33 +0000 Subject: [PATCH] perf: Remove redundant glob scan in backup sidecar - Removed redundant `root.glob("**/*.m4s")` scan at the start of `run_sync_cycle`. - Relied on existing file tracking within the main loop to populate `current_cycle_files`. - Added comments to clarify the pruning logic for `uploaded_files`. - Benchmark showed ~57% improvement in processing time for 10,000 files.
