Oilpan follows V8's project organization, see e.g. on how we accept [contributions](https://v8.dev/docs/contribute) and [provide a stable API](https://v8.dev/docs/api). + +## Threading model + +Oilpan features thread-local garbage collection and assumes heaps are not shared among threads. +In other words, objects are accessed and ultimately reclaimed by the garbage collector on the same thread that allocates them. +This allows Oilpan to run garbage collection in parallel with mutators running in other threads. + +References to objects belonging to another thread's heap are modeled using cross-thread roots. +This is even true for on-heap to on-heap references. + +## Heap partitioning + +Oilpan's heaps are partitioned into spaces. +The space for an object is chosen depending on a number of criteria, e.g.: + +- Objects over 64KiB are allocated in a large object space +- Objects can be assigned to a dedicated custom space. + Custom spaces can also be marked as compactable. +- Other objects are allocated in one of the normal page spaces bucketed depending on their size. + +## Precise and conservative garbage collection + +Oilpan supports two kinds of GCs: + +1. **Conservative GC.** +A GC is called conservative when it is executed while the regular native stack is not empty. +In this case, the native stack might contain references to objects in Oilpan's heap, which should be kept alive. +The GC scans the native stack and treats the pointers discovered via the native stack as part of the root set. +This kind of GC is considered imprecise because values on stack other than references may accidentally appear as references to on-heap object, which means these objects will be kept alive despite being in practice unreachable from the application as an actual reference. + +2. **Precise GC.** +A precise GC is triggered at the end of an event loop, which is controlled by an embedder via a platform. +At this point, it is guaranteed that there are no on-stack references pointing to Oilpan's heap. +This means there is no risk of confusing other value types with references. +Oilpan has precise knowledge of on-heap object layouts, and so it knows exactly where pointers lie in memory. +Oilpan can just start marking from the regular root set and collect all garbage precisely. + +## Atomic, incremental and concurrent garbage collection + +Oilpan has three modes of operation: + +1. **Atomic GC.** +The entire GC cycle, including all its phases (e.g. see [Marking](#Marking-phase) and [Sweeping](#Sweeping-phase)), are executed back to back in a single pause. +This mode of operation is also known as Stop-The-World (STW) garbage collection. +It results in the most jank (due to a single long pause), but is overall the most efficient (e.g. no need for write barriers). + +2. **Incremental GC.** +Garbage collection work is split up into multiple steps which are interleaved with the mutator, i.e. user code chunked into tasks. +Each step is a small chunk of work that is executed either as dedicated tasks between mutator tasks or, as needed, during mutator tasks. +Using incremental GC introduces the need for write barriers that record changes to the object graph so that a consistent state is observed and no objects are accidentally considered dead and reclaimed. +The incremental steps are followed by a smaller atomic pause to finalize garbage collection. +The smaller pause times, due to smaller chunks of work, helps with reducing jank. + +3. **Concurrent GC.** +This is the most common type of GC. +It builds on top of incremental GC and offloads much of the garbage collection work away from the mutator thread and on to background threads. +Using concurrent GC allows the mutator thread to spend less time on GC and more on the actual mutator. + +## Marking phase + +The marking phase consists of the following steps: + +1. Mark all objects in the root set. + +2. Mark all objects transitively reachable from the root set by calling `Trace()` methods defined on each object. + +3. Clear out all weak handles to unreachable objects and run weak callbacks. + +The marking phase can be executed atomically in a stop-the-world manner, in which all 3 steps are executed one after the other. + +Alternatively, it can also be executed incrementally/concurrently. +With incremental/concurrent marking, step 1 is executed in a short pause after which the mutator regains control. +Step 2 is repeatedly executed in an interleaved manner with the mutator. +When the GC is ready to finalize, i.e. step 2 is (almost) finished, another short pause is triggered in which step 2 is finished and step 3 is performed. + +To prevent a user-after-free (UAF) issues it is required for Oilpan to know about all edges in the object graph. +This means that all pointers except on-stack pointers must be wrapped with Oilpan's handles (i.e., Persistent<>, Member<>, WeakMember<>). +Raw pointers to on-heap objects create an edge that Oilpan cannot observe and cause UAF issues +Thus, raw pointers shall not be used to reference on-heap objects (except for raw pointers on native stacks). + +## Sweeping phase + +The sweeping phase consists of the following steps: + +1. Invoke pre-finalizers. +At this point, no destructors have been invoked and no memory has been reclaimed. +Pre-finalizers are allowed to access any other on-heap objects, even those that may get destructed. + +2. Sweeping invokes destructors of the dead (unreachable) objects and reclaims memory to be reused by future allocations. + +Assumptions should not be made about the order and the timing of their execution. +There is no guarantee on the order in which the destructors are invoked. +That's why destructors must not access any other on-heap objects (which might have already been destructed). +If some destructor unavoidably needs to access other on-heap objects, it will have to be converted to a pre-finalizer. +The pre-finalizer is allowed to access other on-heap objects. + +The mutator is resumed before all destructors have ran. +For example, imagine a case where X is a client of Y, and Y holds a list of clients. +If the code relies on X's destructor removing X from the list, there is a risk that Y iterates the list and calls some method of X which may touch other on-heap objects. +This causes a use-after-free. +Care must be taken to make sure that X is explicitly removed from the list before the mutator resumes its execution in a way that doesn't rely on X's destructor (e.g. a pre-finalizer). + +Similar to marking, sweeping can be executed in either an atomic stop-the-world manner or incrementally/concurrently. +With incremental/concurrent sweeping, step 2 is interleaved with mutator. +Incremental/concurrent sweeping can be atomically finalized in case it is needed to trigger another GC cycle. +Even with concurrent sweeping, destructors are guaranteed to run on the thread the object has been allocated on to preserve C++ semantics. + +Notes: + +* Weak processing runs only when the holder object of the WeakMember outlives the pointed object. +If the holder object and the pointed object die at the same time, weak processing doesn't run. +It is wrong to write code assuming that the weak processing always runs. + +* Pre-finalizers are heavy because the thread needs to scan all pre-finalizers at each sweeping phase to determine which pre-finalizers should be invoked (the thread needs to invoke pre-finalizers of dead objects). +Adding pre-finalizers to frequently created objects should be avoided. diff --git a/deps/v8/include/cppgc/default-platform.h b/deps/v8/include/cppgc/default-platform.h index 2ccdeddd8376f4..f9af756c39a0a5 100644 --- a/deps/v8/include/cppgc/default-platform.h +++ b/deps/v8/include/cppgc/default-platform.h @@ -6,7 +6,6 @@ #define INCLUDE_CPPGC_DEFAULT_PLATFORM_H_ #include -#include #include "cppgc/platform.h" #include "libplatform/libplatform.h" @@ -64,6 +63,8 @@ class V8_EXPORT DefaultPlatform : public Platform { return v8_platform_->GetTracingController();
