Bug 178082 – [Readable Streams API] Align queue with spec for ReadableStreamDefaultController

• Component: WebCore Misc.
• Status: RESOLVED FIXED

[Romain Bellessort]

Align ReadableStreamDefaultController handling of queue with latest spec. This will in particular fix some consistency issues, especially with rounding errors. Also applies to WritableStream.

Why did you decide to remove the queue object and subtitute it with two attributes?

I thought current implementation was based on a previous version of the spec and that, while implementing latest behavior for queue, it would be better to align the whole implementation (this in particular makes it easier to compare spec and implementation). 

Are there any drawbacks to replacing the queue object (with two attributes) by two attributes directly owned by the controller? (the need to define both attributes in WebCoreBuiltinNames.h is a significant drawback?) Of course if it is more appropriate, I can prepare a patch that preserves the queue object and only aligns with new behavior.

There are any drawbacks in changing that. Af the moment Youenn and I decided that we preferred this implementation because it does not make too much sense having a queue with two attributes in the original object instead of having just a queue object with those two attributes.

This said, IMHO, I think the implementation would be clearer if you kept it as you could call @newQueue or make @resetQueue create a object with the right reset attributes.

Ok I see the point. I've uploaded a new patch which keeps queue as an object but implements the new behavior. In addition, I've refactored queue for ReadableByteStreamController, so that both queues are implemented in the same way.
