From fec89459e08ef24f162d6317478c18b89d553004 Mon Sep 17 00:00:00 2001 From: Nathaniel Ledford Date: Tue, 20 Oct 2026 17:05:06 -0400 Subject: [PATCH] PERF-SMART: test a smart album's rules cheapest first A rule set is now tested cheapest rule first (numbers, choices and yes/no, then lists and dates, then text and paths, then smart albums), worked out once per prepared filter and per smart album, not per photo. Photos matched are the same; the editor still shows the user's order. While a smart album tests itself, or a chain of smart albums reaches the depth limit, rules are tested as written, since there an answer can depend on which album is asked first.
