r=me assuming no extensions are using this. Do we need dev-doc-needed here?

SeaMonkey is using this.

Unless you know another way of getting the window object...

nsIFeedWriter::Init()?

Let me double-check but I think we ran into some funkiness because we were creating the object from chrome XBL attached to a content page.

I originally thought you were suggesting that we implement nsIFeedWriter, but do you really mean that we should be implementing nsIDOMGlobalPropertyInitializer instead (does that even work for constructors?)

Comment 11

[[e-mail]]

Whoops, I was confusing it with nsIJSNativeInitializer.

Comment 12

[[e-mail]]

Hmm, I guess we can convert the code to be a global property rather than a global constructor, although then it would get created when anyone looked at the property, rather than having to be explicitly created as it is now.

I mean that we should convert it to WebIDL bindings if WebIDL-bound objects are available on users of FeedWriter.js. If not available, we will have to wait until bug 890364.
See also bug 851178.

This was backed out and apparently never commented as such in the bug...

[Ryan VanderMeulen [:RyanVM]]

Missed comment 6. Anyway, better to add a [leave open] to the whiteboard when backing out prior to it even hitting m-c :-)

Are non-libxul components even able to use WebIDL? As I understand it, all of the WebIDL bindings have to be linked into libxul in advance and the contracts hard-coded in.

Hm, I thought the only requirement for JS-implemented WebIDL was adding FeedWriter.webidl in the Core side. Luckily Firefox and SeaMonkey share the same contract id for the ndIFeedWriter implementation.

Comment 19

[Masatoshi Kimura [:emk]]

The interface itself has been restored (see comment #6). But "GlobalObjectConstructor" has been removed from the global anyway because of bug 898817. Add-ons and non-Firefox apps will be able to access the interface through Components.interfaces (and it is the documented way. The global "GlobalObjectConstructor" has never been documented.)

Comment 20

[Masatoshi Kimura [:emk]]

Also, site cannot use this interface. Existence check will be covered by bug 898817.

Comment 21

[Masatoshi Kimura [:emk]]

Bug 1089811 has the latest patch. duping forward.
