<!--

|
|

|
|
|
|
|
|
This testing all gets a bit complicated here; the problem is that our
|
|
|
|
|
document.domain implementation will do a suffix comparison of the value to which
|
|
|
|
|
it's being set against the current URI's base domain (where "base domain" is
|
|
|
|
|
defined as the effective TLD plus one; see nsIEffectiveTLDService.idl). Seems
|
|
|
|
|
simple enough, right? Wrong.
|
|
|
|
|
|
|
|
|
|
The problem, as usual, is IDN. Our current, wholly-inadequate solution to
|
|
|
|
|
preventing Unicode domain-name spoofing is done at the level of the URL
|
|
|
|
|
implementation, not at the presentation level. However, the value of the
|
|
|
|
|
base domain for the current URI is always calculated in punycode; if the
|
|
|
|
|
provided domain is one which is whitelisted, we'll get an IDN name and the
|
|
|
|
|
suffix-comparison will fail. Nice great big mess, huh?
|
|
|
|
|
|
|
|
|
|
Anyway: "test" currently fits the bill as a TLD which is not whitelisted, while
|
|
|
|
|
"δοκιμή" (the Greek IDN TLD for "test") fits the bill as a TLD which is
|
|
|
|
|
whitelisted. RFC 2606 reserves "test" for DNS testing, so nobody's going to
|
|
|
|
|
clamor for it to be whitelisted any time soon. The latter is as of February
|
|
|
|
|
2008 undergoing testing for IDN TLDs, and it's at least temporarily whitelisted
|
|
|
|
|
for now. Once the testing period ends the latter's probably going to be
|
|
|
|
|
un-whitelisted, so we're going to have to do a careful bit of stepping to ensure
|
|
|
|
|
that in the future this test tests what it was intended to test (and, until
|
|
|
|
|
bug 414090 is fixed, that it doesn't break when the Greek TLD is
|
|
|
|
|
un-whitelisted).
