Subject: isolate_holder.patch
|
|
|
|
Pass pre allocated isolate for initialization, node platform
|
|
needs to register on an isolate so that it can be used later
|
|
down in the initialization process of an isolate.
|
|
|
|
Specifically, v8::Isolate::Initialize ends up calling
|
|
NodePlatform::GetForegroundTaskRunner, which requires that the
|
|
isolate has previously been registered with NodePlatform::RegisterIsolate.
|
|
However, if we let gin allocate the isolate, there's no opportunity
|
|
for us to register the isolate in between Isolate::Allocate and
|
|
Isolate::Initialize.
