From cd7c3fce2472656b2a1247429751e43350976677 Mon Sep 17 00:00:00 2001 From: nsfisis Date: Wed, 19 Aug 2026 23:45:38 +0900 Subject: perf(package): hand out link maps behind Rc PackageInterface::getRequires() and friends return the array of Link objects; in PHP that is a copy-on-write array of object references, so a caller pays nothing to look at it. The port returned IndexMap by value, so every call deep-cloned the whole map, keys and constraints included. Pool building calls these accessors once per package per candidate, which put IndexMap::clone at 13.5% of `require laravel/laravel`. Store the maps as Rc> and return a handle. Callers that mutate the map clone it explicitly at the point of mutation, matching where PHP would separate the array.
