Matt Brubeck 84f6c35c0f servo: Merge #19512 - Improve LRU cache behavior in SelectorFlagsMap (from mbrubeck:uluru); r=emilio ... This code used to insert duplicate entries to avoid expensive shuffling of the LRU cache. With uluru this is no longer necessary, because reordering the cache is cheap. Now it uses the `LRUCache::find` method from uluru 0.2 to update entries in-place. This should increase cache hits by eliminating unnecessary evictions. This PR also updates `arrayvec` because `uluru` depends on it, and `immeta` because it depends on `arrayvec`. --- - [x] `./mach build -d` does not report any errors - [x] `./mach test-tidy` does not report any errors - [x] These changes do not require tests because they don't change behavior Source-Repo: https://github.com/servo/servo Source-Revision: 0c13f14aaa151764e1b3dd2d4503cb6fc3c9595b --HG-- extra : subtree_source : https%3A//hg.mozilla.org/projects/converted-servo-linear extra : subtree_revision : b1551f8e564b25ef5a332d0492584e8e179e9325		2017-12-07 16:02:44 -06:00
