Let's convert inIDOMUtils to a Web IDL interface so that we don't have to deal with DOM-related XPIDL interfaces.
https://treeherder.mozilla.org/#/jobs?repo=try&revision=12ababb881f09d4969345a68e604ae7d9a96dca3

The layout/inspector/tests/chrome/test_parseStyleSheetObservers.html failure in the TV job seems to be because that test doesn't pass when it's run by itself (verified by pushing a try run with some white space only change to that file).

Boris, let me know if folding most of these patches down would be easier to review.  Probably someone else could have reviewed these, but since nearly all of them also need a DOM peer's review, and each patch isn't too complicated, seemed easiest just to give them to you.
Also, please let me know if there's a way to avoid the GlobalObject& argument in all these static methods, since none of them need to use it.

Hmm, my git-cinnabar checkout doesn't seem to have recorded this as a rename plus changes, unfortunately. :(

Thanks for the patch.  The devtools parts look good to me.  I did not really examine the other parts.

Could you file a followup bug on that?  Seems nasty.

If you make that last arg `[TreatNullAs=EmptyString]`, I am guessing you can remove the `|| ""` bits you had to add in a few cases.  Might be nicer that way.

aElement.OwnerDoc() is probably clearer, now that we have an Element here.

r=me with the function signature bits fixed.

Why not just have this return a CSSLexer, then, instead of `any`?  We couldn't do that in xpidl, because it knows nothing about CSSLexer, but webidl does!

And this bit would then live in the binding-generated code.  So you'd just have this method body look like this:

    return new CSSLexer(aText);
    
and can remove the [Throws] annotation in the webidl too.

StyleRule is already WebIDL.  This should probably reference a bug filed to add chromeonly APIs to it.  Failing that, at least remove the "once we move" bits here?

Why are we doing this here, not at the IDL level?

I would think the arg in the webidl should be a CSSStyleRule, not a CSSRule.  Then the bindings will enforce that we have a StyleRule here.

I believe that will allow you to remove the [Throws] annotation too.  

This applies to all the methods you're moving over in this patch.

> -  *aCount = rule->GetSelectorCount();

And the type bindings use for CSSStyleRule is already BindingStyleRule, so you won't need this cast.

This ends up doing two copies (because all the strings are short), but that's probably fine here...  If we wanted to avoid that, we could AppendElement() with no arg and then CopyASCIIToUTF16 into the new thing or so.

Is there a reason to not return NodeList here?  It would avoid copying and the semantic changes being introduces (live vs non-live).

You could make this `nsCOMPtr<nsINodeList>`.

If kids were nsINodeList, you could do:

    uint32_t length = kids->Length();

Please do:

    aResult.AppendElement(kids->Item(i));
    
or so.  That's assuming we want to keep returning a sequence.

You can't assert that.  There is no ESM if no shell (which we should fix, but haven't yet).

The memory ownership model could sure use documenting.  I would feel a lot happier about this code not leaking if the hashtable owned the InspectorFontFace instances explicitly until we moved them out into aResult...  Any way to set that up?

Shouldn't the return type be `DOMString?` in that case?  Of if it can't actually be null (per the impl), should the docs here be fixed?

colorNameToRgb is unused in comm-central, but it does look like the rest of the APIs I'm removing are used in the old DOM inspector extension that's still in the tree there.

Jörg, can you tell me if the inspector extension in the tree at comm-central/extensions/inspector/ is still being used?  If so, I might have to migrate these few inIDOMUtils methods that I was planning on removing to InspectorUtils.

> Mistakenly thought I was removing a getContentState test; will restore.

After restoring, I remember the real reason I removed it. :-)  It's testing that passing false for the second argument throws an exception.  Switching to Web IDL bindings no longer throws an exception since the false gets converted to unsigned long long 0.  I don't think it's worth keeping the test by passing in some other value for the second argument; we've probably got enough Web IDL binding tests for argument conversion.

This is losing the exception for out-of-range aSelectorIndex, no?  Should propagate it out.  Same for GetSpecificity and SelectorMatchesElement.

The developer documentation for this could use an update to reflect the new name of the interface. (I happened across https://developer.mozilla.org/en-US/docs/Mozilla/Tech/XPCOM/Reference/Interface/inIDOMUtils recently; not sure if there are other references to it that should also be updated.)
Keywords: dev-doc-needed
I know very little about this side of things, and we don't really support the internals docs as such any more...but I'll make time for it if I can.

Is this basically just a simple interface name change, from inIDOMUtils to InspectorUtils, or is there more to it?

It's more than just that, IIUC; methods are updated to return WebIDL types, which may not be exactly the same as the old XPCOM types that were being used. And we no longer use Cc["..."].getService(...) to access this (it's SpecialPowers.InspectorUtils now), so example code is out of date in that respect, too.

Cameron, can you give any guidance here?

I feel like having documentation in MDN for inIDOMUtils was useful at a time when it was possible to use by extensions.  But now it really is just an internal thing for our own devtools to use, it's enough for developers to rely on whatever documentation exists in code for these things.  So I would suggest removing the inIDOMUtils content on MDN.

WDYT Chris?

If you think that is OK, I am happy to remove it. Is there a particular URL I should point to, or shall I just say something like "document deleted, as in-code documentation is more current"?

I think it would be fine to say that nsIDOMUtils was converted to Web IDL, and is now called InspectorUtils, and to see documentation in that class's header file.
