      "message": "Remove mirror:: and ArtMethod deps in utils.{h,cc}\n\nThe latest chapter in the ongoing saga of attempting to dump a DEX\nfile without having to start a whole runtime instance.  This episode\nfinds us removing references to ArtMethod/ArtField/mirror.\n\nOne aspect of this change that I would like to call out specfically\nis that the utils versions of the \"Pretty*\" functions all were written\nto accept nullptr as an argument.  I have split these functions up as\nfollows:\n1) an instance method, such as PrettyClass that obviously requires\nthis !\u003d nullptr.\n2) a static method, that behaves the same way as the util method, but\ncalls the instance method if p !\u003d nullptr.\nThis requires using a full class qualifier for the static methods,\nwhich isn\u0027t exactly beautiful.  I have tried to remove as many cases\nas possible where it was clear p !\u003d nullptr.\n\nBug: 22322814\nTest: test-art-host\nChange-Id: I21adee3614aa697aa580cd1b86b72d9206e1cb24\n"

This only\nconcerns class initialization happening at compilation time when generating an\nimage (like boot.art for the system).\n\nIn transactional mode, we log every object\u0027s field assignment and array update.\nTherefore we\u0027re able to abort a transaction to restore values of fields and\narray as they were before the transaction starts. We also log changes to the\nintern string table so we can restore its state prior to transaction start.\n\nSince transactional mode only happens at compilation time, we don\u0027t need to log\nall these changes at runtime. In order to reduce the overhead of testing if\ntransactional mode is on/off, we templatize interfaces of mirror::Object and\nmirror::Array, respectively responsible for setting a field and setting an\narray element.\n\nFor various reasons, we skip some specific fields from transaction:\n- Object\u0027s class and array\u0027s length must remain unchanged so garbage collector\ncan compute object\u0027s size.\n- Immutable fields only set during class loading: list of fields, method,\ndex caches, vtables, ... as all classes have been loaded and verified before a\ntransaction occurs.\n- Object\u0027s monitor for performance reason.\n\nBefore generating the image, we browse the heap to collect objects that need to\nbe written into it. Since the heap may still holds references to unreachable\nobjects due to aborted transactions, we trigger one collection at the end of\nthe class preinitialization phase.\n\nSince the transaction is held by the runtime and all compilation threads share\nthe same runtime, we need to ensure only one compilation thread has exclusive\naccess to the runtime. To workaround this issue, we force class initialization\nphase to run with only one thread. Note this is only done when generating image\nso application compilation is not impacted. This issue will be addressed in a\nseparate CL.\n\nBug: 9676614\nChange-Id: I221910a9183a5ba6c2b99a277f5a5a68bc69b5f9\n"

      "message": "Compacting collector.\n\nThe compacting collector is currently similar to semispace. It works by\ncopying objects back and forth between two bump pointer spaces. There\nare types of objects which are \"non-movable\" due to current runtime\nlimitations. These are Classes, Methods, and Fields.\n\nBump pointer spaces are a new type of continuous alloc space which have\nno lock in the allocation code path. When you allocate from these it uses\natomic operations to increase an index. Traversing the objects in the bump\npointer space relies on Object::SizeOf matching the allocated size exactly.\n\nRuntime changes:\nJNI::GetArrayElements returns copies objects if you attempt to get the\nbacking data of a movable array. For GetArrayElementsCritical, we return\ndirect backing storage for any types of arrays, but temporarily disable\nthe GC until the critical region is completed.\n\nAdded a new runtime call called VisitObjects, this is used in place of\nthe old pattern which was flushing the allocation stack and walking\nthe bitmaps.\n\nChanged image writer to be compaction safe and use object monitor word\nfor forwarding addresses.\n\nAdded a bunch of added SIRTs to ClassLinker, MethodLinker, etc..\n\nTODO: Enable switching allocators, compacting on background, etc..\n\nBug: 8981901\n\nChange-Id: I3c886fd322a6eef2b99388d19a765042ec26ab99\n"
