Perflib is used when processing the heap dump to populate the\ninformation initially, but afterwards all views and handlers go\nthrough the new com.android.ahat.heapdump API.\n\nThe primary motivation for this change is to facilitate adding support\nfor diffing two heap dumps to ahat. The new API provides flexibility\nthat will make it easier to form links between objects in different\nsnapshots and introduce place holder objects to show when there is an\nobject in another snapshot that has no corresponding object in this\nsnapshot.\n\nA large number of test cases were added to cover missing cases\ndiscovered in the process of refactoring ahat\u0027s perflib API.\n\nThe external user-facing UI may have minor cosmetic changes, but\notherwise is unchanged.\n\nTest: m ahat-test, with many new tests added.\nBug: 33770653\n\nChange-Id: I1a6b05ea469ebbbac67d99129dd9faa457b4d17e\n" }, { "commit": "932b19ae77b2b15635ea5060baec0ca939d5db86", "tree": "75c04a4f24ae5f1078fb58180ce686d5d0d51d52", "parents": [ "424c03aac25835febbf5c695b943206bc40ef335" ], "author": { "name": "Paul Duffin", "email": "paulduffin@google.com", "time": "Mon Nov 28 16:34:59 2016 +0000" }, "committer": { "name": "Paul Duffin", "email": "paulduffin@google.com", "time": "Mon Nov 28 16:34:59 2016 +0000" }, "message": "Use junit-host instead of junit\n\nBug: 30188076\nTest: make checkbuild\nChange-Id: Ia54aeae56f49123885765bc896c00fd363e93c26\n" }, { "commit": "ec78c78508fa5ef6bac78ee2face0d30e67cf913", "tree": "f9959d9b691d35af9d4940703750523b7b5bd26e", "parents": [ "a8188191477b7b5b01a3c4426c51c48cd55f6678" ], "author": { "name": "Richard Uhler", "email": "ruhler@google.com", "time": "Fri May 13 14:19:37 2016 -0700" }, "committer": { "name": "Richard Uhler", "email": "ruhler@google.com", "time": "Fri Oct 21 16:24:07 2016 +0100" }, "message": "Add support for proguard deobfuscation.\n\nTest: m ahat-test, with obfuscation of test-dump.hprof added.\nBug: 25812772\nChange-Id: I0f257432da570aa146e6bb5c549f014aecc0c326\n" }, { "commit": "6928649223312692f9e2401c34dac37510ddbb2f", "tree": "19ddf5c68cf9e8c93e0a11cba756ceaed4be72a7", "parents": [ "ad1f0ad512cac82e5db05aa8237608ba8424c130" ], "author": { "name": "Richard Uhler", "email": "ruhler@google.com", "time": "Tue Sep 20 10:41:47 2016 +0100" }, "committer": { "name": "Richard Uhler", "email": "ruhler@google.com", "time": "Mon Sep 26 11:44:16 2016 +0100" }, "message": "ahat: Show GC Root Paths.\n\nThe Dominator Path in the objects view is replaced by an augmented\nSample Path from GC Root, which includes non-dominator objects\nalong a sample path and field names.\n\nAlso, use blanks instead of \"0\" in heap tables when the size is 0.\nThis cleans up the pages a little, and conveniently lets us\ndistinguish between dominator and non-dominator objects in the Sample\nPath from GC Root.\n\nTest: m ahat-test, with new InstanceUtils.gcRootPath test added.\n\nBug: 27299030\nChange-Id: I53d75f9dcb3157c2b5b3afc74958711536cd67b6\n" }, { "commit": "cd8a057350aceab9ca48a4720aaa21806b041799", "tree": "378276e297f3001b0b5698fae2a833da7219572a", "parents": [ "be3a3ee02f148345ba6e1a0361532a3f7e8c0002" ], "author": { "name": "Dan Willemsen", "email": "dwillemsen@google.com", "time": "Fri Sep 16 17:11:36 2016 -0700" }, "committer": { "name": "Dan Willemsen", "email": "dwillemsen@google.com", "time": "Fri Sep 16 17:35:21 2016 -0700" }, "message": "Move ART_HOST_TEST_DIR to Android.common_test.mk\n\nI\u0027m improving Kati\u0027s re-run detection, and this $(shell echo $$PPID) now\nnow causes us to reparse all of the makefiles every time, since it\nreally does change on each execution.
