  "message": "Refresh TaskTree.Nodes when getting them\n\nWith the introduction of Change properties, Node attributes and their\nsubnodes may depend on the specific change properties they were created\nfor. In order to correct current over-caching behavior which results in\nerroneous Node contents when more than one change is evaluated, refresh\na Node\u0027s attributes that may be dependent on that change anytime the\nNode is returned by a parent Node. Throwing away subnodes from a Node\ncan be expensive since it results in all the Nodes\u0027 descendants also\nbeing discarded. To reduce this cost, this change reuses subnodes with\nthe same key after a refresh.\n\nAlso enhance the test framework to have a test suite which evaluates a\nsecond change\u0027s output to ensure that the output is updated\nappropriately beyond the first change.\n\nDespite much re-use, this change still results in an approximate 5x\nperformance degradation on our Gerrit 2.7 fork.\n\nChange-Id: Ib598b4c3a8e4fdbef0f41027cb1e6c7be5abe0d8\n",
