[modules] Expand API to allow linking and use it in d8 This patch gives the ability for the embedder to ask for the module requests of a module, and to pass a ResolveCallback into Module::Instantiate(). In d8, I've implemented a simple module_map that's used along with this API to allow loading, compiling, instantiating, and evaluating a whole tree of modules. No path resolution is yet implemented, meaning that all import paths are relative to whatever directory d8 runs in. And no imports are linked to the exports of the requested module.

Reland "[top-level-await] Implement top-level-await in V8" The first land did not correctly handle exceptions for already evaluated modules. Original description: Implements AsyncModules in SourceTextModule. However, there is no support in the parser or D8 for actually creating / resolving AsyncModules. Also adds a flag '--top-level-await,' but the only external facing change with the flag enabled is that Module::Evaluate returns a promise.

[modules] Add refactored API to get ModuleRequests and expose import assertions This change refactors the v8.h API as discussed in https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY/edit#heading=h.q0c9h4p928mn such that a v8::Module exposes module requests as a FixedArray of ModuleRequest objects, which can then be used to obtain their module specifier and source code offset. This replaces the old functions that passed back individual specifier Strings and Locations via repeated calls to getters that take an index. These are marked as deprecated. The new ModuleRequest interface includes a getter for an ImportAssertions FixedArray, which will contain the import assertions for the request if --harmony-import-assertions is set, and will be empty otherwise. One notable change here is that the APIs now return source code offsets rather than v8::Locations. The host must then call the new Module::SourceOffsetToLocation to convert these offsets into line/column numbers. This requires a bit more back-and-forth, but allows the host to defer the cost of converting from source offset to line/column numbers until an error needs to be reported, potentially skipping the work altogether.

[modules] Expand API to allow linking and use it in d8 This patch gives the ability for the embedder to ask for the module requests of a module, and to pass a ResolveCallback into Module::Instantiate(). In d8, I've implemented a simple module_map that's used along with this API to allow loading, compiling, instantiating, and evaluating a whole tree of modules. No path resolution is yet implemented, meaning that all import paths are relative to whatever directory d8 runs in. And no imports are linked to the exports of the requested module.

Until ResolveCallback is removed, InstantiateModule and associated functions are modified to accept both types of callback, using the new one if it was supplied and the old one otherwise. An alternative that I chose not to go with would be to just duplicate InstantiateModule and associated functions for both callback types.

[modules] Expand API to allow linking and use it in d8 This patch gives the ability for the embedder to ask for the module requests of a module, and to pass a ResolveCallback into Module::Instantiate(). In d8, I've implemented a simple module_map that's used along with this API to allow loading, compiling, instantiating, and evaluating a whole tree of modules. No path resolution is yet implemented, meaning that all import paths are relative to whatever directory d8 runs in. And no imports are linked to the exports of the requested module.

[modules] Add ResolveModuleCallback that takes import assertions This change completes the necessary API changes for import assertions discussed in https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY. The old ResolveCallback is deprecated and replaced with a ResolveModuleCallback that includes import assertions. Until ResolveCallback is removed, InstantiateModule and associated functions are modified to accept both types of callback, using the new one if it was supplied and the old one otherwise. An alternative that I chose not to go with would be to just duplicate InstantiateModule and associated functions for both callback types. SyntheticModule::PrepareInstantiate's callback parameter was unused so I removed it.

MaybeLocal<Module> ResolveCallbackForModuleEvaluationError2(
[modules] Add ResolveModuleCallback that takes import assertions This change completes the necessary API changes for import assertions discussed in https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY. The old ResolveCallback is deprecated and replaced with a ResolveModuleCallback that includes import assertions. Until ResolveCallback is removed, InstantiateModule and associated functions are modified to accept both types of callback, using the new one if it was supplied and the old one otherwise. An alternative that I chose not to go with would be to just duplicate InstantiateModule and associated functions for both callback types. SyntheticModule::PrepareInstantiate's callback parameter was unused so I removed it.

[weakrefs] Call Isolate::ClearKeptObjects() as part of microtask checkpoint In the spec, WeakRefs that are dereferenced are kept alive until there's no JS on the stack, and then the host is expected to call ClearKeptObjects to clear those strong references [1]. HTML calls ClearKeptObjects at the end of a PerformMicrotaskCheckpoint [2]. In V8, leaving this up to the embedder is error prone in the same way the deprecated FinalizationGroup callback APIs were error prone: it depends on the embedder doing the right thing. This CL moves the call to ClearKeptObjects to be after running of microtasks within V8. However, the Isolate::ClearKeptObjects API should not be removed or deprecated in case an embedder uses an entirely custom MicrotaskQueue implementation and invokes MicrotaskQueue::PerformCheckpoint manually.

[top-level-await] Implement v8::Module::IsGraphAsync() This is a predicate checking if any module in a module graph is [[Async]], i.e. contains a top-level await. It is needed for ServiceWorker integration, as ServiceWorkers disallows top-level await in its modules to prevent stalling during registration. https://github.com/w3c/ServiceWorker/pull/1444 Bug: v8:9344 Change-Id: Id84489bc73717b4c9950059c8ff6def9297499d0 Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2451212 Commit-Queue: Shu-yu Guo <syg@chromium.org> Reviewed-by: Camillo Bruni <cbruni@chromium.org> Reviewed-by: Georg Neis <neis@chromium.org> Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Cr-Commit-Position: refs/heads/master@{#70390}

[modules] Add ResolveModuleCallback that takes import assertions This change completes the necessary API changes for import assertions discussed in https://docs.google.com/document/d/1yuXgNHSbTAPubT1Mg0JXp5uTrfirkvO1g5cHHCe-LmY. The old ResolveCallback is deprecated and replaced with a ResolveModuleCallback that includes import assertions. Until ResolveCallback is removed, InstantiateModule and associated functions are modified to accept both types of callback, using the new one if it was supplied and the old one otherwise. An alternative that I chose not to go with would be to just duplicate InstantiateModule and associated functions for both callback types. SyntheticModule::PrepareInstantiate's callback parameter was unused so I removed it.
