See https://www.w3.org/Bugs/Public/show_bug.cgi?id=23535 for rationale. This should work across URL / Location / HTMLAnchorElement / HTMLAreaElement. I.e. across URLUtils.
Is this change going to be web compatible? (I guess we need to see?)
Per arv in that bug it is fully Chrome-compatible. And apart from Location.port it is compatible with all other browsers. And we used to throw for Location.port so that seems like low-risk. However, if there are Gecko-specific code paths out there on the web we could be in trouble, as always.

Comment on attachment 8351260 [details] [diff] [review] p.patch >+ ok(url.port === '', 'URL.port is \'\''); Use ise() instead, please. r=me, though I'd like to have Honza look at this too. Does this fix the behavior of location.port too, or does that need a separate bug?

Comment on attachment 8351260 [details] [diff] [review] p.patch Oh, and maybe add tests for <a> and location?

> Testing location it's hard Well, you'd have to do it in a subframe. But OK.
Wait. Where is <a> tested? I don't see it in the patch...
test_url_empty_port.html: <a id="link" href="http://www.example.com:8080">foobar</a> var link = document.getElementById("link"); is(link.port, 8080, 'URL.port is 8080'); ...
Oh, I see. I thought that was testing a <link>. Alright, then!
Looking into the patch... Needs a bit more thinking.

Yes. we are moving in this direction with this patch. The spec will be updated once this patch is landed. Basically the idea is url.port = '' => default port. url.port = '0' => port == 0.
