Yes I have a global to the context sill open, I guess my question does it
have to be reset before snapshotting or is there a way to ignore them or
serialize it.
I know if i reset the global it works. That suggest to me that any
global/persistent handles tracking JS objects in c++ code all have to be
closed before the snapshot and you don't want to use eternals either.
You can see the can view the src of my playground test where i'm working
through the snapshot process
here:
https://github.com/v8App/v8App/blob/snapshots/src/testing/libs/jsRuntime/runtime/JSSnapshotCreatorTest.cc
My main question was how do i keep an obj created via new in JS backed by a
C++ class from being GCed before snapshotting. I gues I may not understand
what objects get sent to the SerializeInternalFields callbaclk.
