Web Inspector: Show Internal properties of PaymentRequest in Web Inspector Console

Show Internal properties of PaymentRequest in Web Inspector Console

Internal Slots worth showing:
<https://w3c.github.io/payment-request/#internal-slots>
[[state]] - Current state of the payment request ("created" || "interactive" || "closed")
[[options]] - The PaymentOptions supplied to the constructor.
[[details]] - The PaymentDetailsBase for the payment request initially supplied to the constructor and then updated with calls to updateWith().

I started with state / options. I didn't do details yet but I suppose that would be the most useful (a large JSON construction of the PaymentDetails).

I hate doing stuff like this. One thing we can do is put the inspector tests as a sub-directory of the feature, or a feature dir in inspector:

    http/tests/paymentrequest/inspector
    http/tests/inspector/paymentrequest

That would mean inspector tests are all over the place, or lots of small directories. But thats probably fine / cleaner. I prefer the 2nd.

Here we can do the same kind of thing for paymentDetails. Is there already a way to convert it to a JSON / JavaScript object?

This shows internal slots for [[state]], [[options]], and [[details]]. Details probably being the most useful, since this has basically everything!

Oops.

I didn't include the "showPromise" / [[acceptPromise]], resolution value of the payment request because that is a DOMPromiseDeferred in WebCore which only holds a JSC::Weak reference to the actual JSPromise, which gets cleared after the promise is resolved. So any access to DOMPromiseDeferred::promise after resolution crashes... Rather than changing the lifetime of this Promise I just decided to not show it. Maybe we can improve that later if we think its useful.

This should be good to review now.

This adds:

    internals.withUserGesture(callback);

Which we alias on UIHelper:

    UIHelper.withUserGesture(callback);

To simplify running code inside of a user gesture.

Test failure is unrelated, and is happening everywhere not just here.

I think all of this is unnecessary detail given the implementation below. I'll just remove it.

It would be nice if the bindings generator could generate all the code you added to WebInjectedScriptHost. Patch looks good otherwise.

I'm not sure why we need a wrapper function in ui-helper.js when we could just call the internals method directly.

Wenson thought UIHelper would be a more natural place for it / where people would look for it, so I put it here so it'll be more likely to found.

Should scope.release() be called?

This can just be put inside of the ENABLE(PAYMENT_REQUEST) for now then. You'll probably need to do:

If you can test, can you make such a change?

Sure. I'll do it in Bug 179524.
