1054029 - TypedArrays do not work with JS-implemented WebIDL

Status: RESOLVED DUPLICATE of bug 929609

(Core :: DOM: Core & HTML, defect)

Description

[psiddh]

Using TypedArrays such as Uint8Array do not generate MozXXXBindings correctly and the compilation fails subsequently. 

For instance, in the webidl , if the declaration happens to be the following, compilation fails while trying to generate MozXXXBindings.

  [Throws]
  Promise<void> testInterface(Uint8Array aid);

However if it is changes to sequence of octets , compilation seems to be ok and bindings do get generated properly.

  [Throws]
  Promise<void> testInterface(sequence<octet> aid);

After discussing with bholley, raising the bug and 'needinfo Andrew McCreight :mccr8'.

There is an ongoing proposal (initial draft) on Secure Element APIs 'https://bugzilla.mozilla.org/show_bug.cgi?id=879861' and it should ideally use typed Arrays in its APIs. This API is slated for 2.2 REL.

Do you mean it doesn't work with JS-implemented WebIDL, or it doesn't work at all?

Comment 2

[psiddh]

I think it doesn't work with JS-implemented interfaces.

Ah, right, you did say that in the name of the bug.
