Bug ID: 52253
Summary: Protocol-relative URLs break the internet
Product: MediaWiki
Version: 1.22-git
Hardware: All
OS: All
Status: NEW
Severity: normal
Priority: Unprioritized
Component: General/Unknown

Protocol-relative URLs might be various kinds of awesome, and they work with
every major browser. The problem with them is, they break many things that are
not browsers. It's easy to write an app that fetches some HTML with HTTP, but
less easy to correctly interpret that HTML. Using obscure features like
protocol-relative URLs causes the less carefully-written HTTP clients to break.
Access logs demonstrate that there are many broken clients:

Note that the browser-like UA strings might not be fake -- Flash and Java apps
running under the browser send the UA string of their host. Of the UA strings
without "Mozilla" in them, we have:
* Three versions of perl, two Java libraries
* Microsoft BITS (a background download helper, probably used by an offline
reader app)
* KongshareVpn (website defunct)
* Instapaper (an offline downloader/reader for Android)
* Googlebot-Image (IP confirmed to be Google)
* A couple of phone models (Dorado, Symbian)
The length of this list is limited by the sample size, not by the actual number
of broken scripts. It's a long, long tail.
This is just a gripe bug, I don't have any concrete plan for replacing
protocol-relative URLs in our infrastructure. Krinkle asked me about it at
I4155c740 , so I thought I may as well document the problem.
