From 0b599712a7dfce3f09cdd817ede5089833bbb6e6 Mon Sep 17 00:00:00 2001 From: Boris Zbarsky Date: Tue, 23 Apr 2024 16:34:30 -0400 Subject: [PATCH] Use NSCache for the MTRDevice attribute cache when possible. When we are storing our cluster data persistently, we don't have to ensure it's pinned in memory all the time. Use NSCache, and reload from storage as needed. --- src/darwin/Framework/CHIP/MTRDevice.mm | 186 +++++++++++++----- .../Framework/CHIP/MTRDeviceController.mm | 4 +- .../CHIP/MTRDeviceControllerDataStore.h | 1 + .../CHIP/MTRDeviceControllerDataStore.mm | 12 ++ .../Framework/CHIP/MTRDevice_Internal.h | 4 +- .../Framework/CHIPTests/MTRDeviceTests.m | 31 ++- .../CHIPTests/MTRSwiftDeviceTests.swift | 74 ++++++- .../TestHelpers/MTRTestDeclarations.h | 1 + 8 files changed, 243 insertions(+), 70 deletions(-) diff --git a/src/darwin/Framework/CHIP/MTRDevice.mm b/src/darwin/Framework/CHIP/MTRDevice.mm index 7c02df267a8ad7..f4006fcbcc7f3c 100644 --- a/src/darwin/Framework/CHIP/MTRDevice.mm +++ b/src/darwin/Framework/CHIP/MTRDevice.mm @@ -361,10 +361,17 @@ @implementation MTRDevice { #endif BOOL _delegateDeviceCachePrimedCalled; - // With MTRDeviceClusterData now able to hold attribute data, the plan is to move to using it - // as the read cache, should testing prove attribute storage by cluster is the better solution. - NSMutableDictionary * _clusterData; - NSMutableSet * _clustersToPersist; + // _clusterData stores data that we have already persisted (when we have + // cluster data persistence enabled).
