Unified heap support in V8 requires having another (at least internal) heap that implements a unfied garbage collection strategy. This will not re-use the already existing cppgc::Heap because there should be no way in creating such a heap externally or scheduling stand-alone garbage collections. In order to have a common token, this CL introduces AllocationHandle which can be passed to MakeGarbageCollected to allocate C++ objects. V8 (soon) and the stand-alone heap both have methods to retrieve such a handle. This works around a problem with creating diamond class hierarchies when a base class would be exposed on the public API level. Fast paths for Blink are still possible because allocation handles can be cached the same way (e.g. global, or TLS) as a heap can be cached.

This fixes two issues: - labs resetting didn't account bytes as beeing freed; - large object were not accounted. The CL introduces a single bottleneck for labs resetting in ObjectAllocator, which is aware of StatsCollector. This way NormalSpace is treated as a value object and all invariants are maintained by ObjectAllocator (and Sweeper).

Adds allocation-based heap growing strategy that triggers GC based on some limit. The limit is computed based on previous live memory and a constant growing factor. For invoking GC, we support two modes: with and without conservative stack scanning. Without conservative stack scanning, an invoker makes sure that we schedule a GC without stack using the existing platform.

This ports HeapStatsCollector (former ThreadHeapStatsCollector) from Blink. The CL only ports accounting of allocated object size which is needed for a simple growing strategy in a follow up. HeapStatsCollector is a global dependency for most sub components as it provides infrastructure for measuring time (through trace scopes) and space. The general idea of HeapStatsCollector is to act as sink where all sub components push time and space information. This information is then gathered and made available via an event that is implemented as POD. Time-dependent info is available through regular getters (pull) and observers (push).

Split platform into a process-global initialization part and per-heap platform objects. These platform objects still contain allocators and executors. With per-heap platforms GetForegroundTaskRunner() returns by definition the correct runner. In future, when initialized throuhg V8, an adapter can be used to translate between the different platforms, avoiding the needed for V8 embedders to provide additional information.

This CL adds 2 new values to the EmbedderStackState enum with more explicit names. The old values are updated as aliases to the new values and marked as soon to be deprecated. This CL also moves the enum to v8-platform.h so that it can be reused by cppgc. Depracating individual values in an enum is supported by GCC only since version 6. Thus new macros were needed for the deprecation (which delegate to the existing macros when supported). GCC versions older than 6 are still used by the CQ bots.

This patch provides infrastructure to pin object types to specific spaces. This allows embedders to create mutual exclusive arenas for certain (base) types. In future, this will also be used to provide sliding-window compaction on certain custom spaces. We mainly preserve the existing infrastructure with the difference that spaces are now slightly more dynamic than in Blink as they are kept in a vector instead of a fixed-size array. The mechanism differs from Blink in that it does not allow the user object to call allocation methods directly but instead provides a trait that can be overridden to specify a custom space. The patch preserves templatization for objects that do not go into custom spaces to safe a branch in the allocation hot path.

This adds the following: 1) Heap object structure classes: RawHeap, BaseArena and BasePage. - freelist - linear allocation block 2) ObjectAllocator, a class responsible for object (and page) allocation. The design doc with UML design: https://bit.ly/2VVTcqc User defined arenas are followup.

Introduce LivenessBroker which is a temporary broker object to expose liveness during specific garbage collection phases. This broker can be used to handle: - PreFinalizer - Custom weak callbacks - Internal weak callbacks used for WeakMember Change-Id: I3870c2b89b2538f04feabf2eb7a4676ce2fe7d61 Bug: chromium:1056170 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2144059Reviewed-by:

This CL provides a basic allocator that allocates normal-sized objects on pages without ever reusing them. This allows for already using the backref from page to heap which is used in some critical places (pre-finalizers, write barrier, Persistent).

Neither Member, nor GarbageCollected objects (and friends) should be allocated on the stack. Create a special test fixture that allows for writing idiomatic unit tests that depend on allocation but do not pull in garbage collection.

This CL adds basic infrastructure for: - MakeGarbageCollected - GarbageCollected and related type traits - Heap (API / internal) - Basic allocation based on malloc - CollectGarbage without marking This allows for allocation and reclamation through an explicit GC call. No objects are held alive from any source (stack, globals, refs), yet. The exact wiring of platform is future work.
