access document.domain at about:plugins produces NS_ERROR_FAILURE. No error at about:config


(Core :: Security, defect)

Windows XP
Not set

I'm checking the domain on every page load in my extension and I noticed that when aobut:plugins load I get:

Error: Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMNSHTMLDocument.domain]
Source file: chrome://tdccms/content/main.js
Line: 518

it does NOT happen when I load about:config or about:cache. It only seems to happen when I load about:plugins

why? is there something special with about:plugins or is this a bug?

I don't have a good answer... unlike the others, though, about:plugins is created using document.write(), wonder if that has anything to do with it.
Is this still a problem?

Ever confirmed: false
Bug 417021 that is. Sorry, did not mean to change status.
Ever confirmed: true
about:plugins is not XHTML, so no.

What it is is system-principal, so there is no principal URI to be had.

I guess we could just return "" in this case instead of throwing if someone cares about this case...  That would sort of match the spec.

I will like to work on this. 
Boris, can you hint me where to find to relevant code.
Flags: needinfo?(bzbarsky)
And also is this on all platforms or just WIN?
This is all platforms, and the relevant code is in nsHTMLDocument::GetDomain over in dom/html/nsHTMLDocument.cpp

Akshendra Pratap Singh, why did you remove the review request?  Was there an issue with the patch?
Flags: needinfo?(akshendra521994)
I thought that there could be a better solution then the one I tried in this patch. But since then I didn't got much time to look at that because of my academics. I will submit a new one within this week.
Am sorry if that caused any trouble. :)
Flags: needinfo?(akshendra521994)
No, no trouble, just making sure you're not waiting on me or something.  ;)

Did this fix bug 417021 as well? Or can the getter still throw?
Yes, it did.  We should remove the Throws annontation from the IDL.

Does that mean I have to remove the use of ErrorResult& rv?

No, this is removing GetDomain from nsIDOMHTMLDocument, which is not desirable.

Instead, you can just have the getter be NS_IMETHODIMP and make sure it always returns NS_OK.

I'm really confused. A patch already landed in this bug and now we're landing another patch that appears to not be built on top of it? Oh, and the previously landed patch is on Aurora now too.

Can we please sort this mess out before landing more under this bug number?

Ryan, the follow up patch is cleanup. I guess it doesn't matter whether that misses a train.
Yeah, the second patch should really have gone into a separate bug, imo....  Akshendra Pratap Singh, would you re-resolving this bug and creating a new one for landing the cleanup?
Flags: needinfo?(akshendra521994)
Actually just re-resolving.  Please put the followup into a separate bug.
