Nits made me ask a question about timing.

Could these be const length2
and const buf2
please?
Recycling variables should be avoided.

Could this be const arrayBufferViewsLength
instead.

Which made be think isn't there a race here?
Is the callbacks guaranteed to be in order?
At minimum this should be documented in a comment

Is the callbacks guaranteed to be in order?
Yes. We have only one HostObject
so that the callback will be called only once.
I think v8.Serializer.writeRawBytes()
being expected to be called inside of the callback of _writeHostObject
makes the test a bit confusing. I'm going to refactor this.
@oyyd as alway thank you for the contribution. While reviewing the code and looking at cases of variable recycling I found that I don't understand the operation order guarantee. |

Maybe simplest solution is to add a sentinel:
let has_writeHostObjectCalled = false;
the in _writeHostObject
has_writeHostObjectCalled = true;
the first line of _readHostObject
assert.ok(has_writeHostObjectCalled);

or dual use arrayBufferViewsLength
- initialise it to false
, and then assert
des._readHostObject = common.mustCall(() => {
assert.notStrictEqual(false, arrayBufferViewsLength);
...
@refack Thanks for your advice! Comments addressed. I have separated the test for |
Looks 💯. Thank you for following up! |
