667087 - Cookies cannot be stored with single character hostnames

Status: VERIFIED FIXED

(Core :: Networking: Cookies, defect)

Description

[Chris Coulson]

I'm reporting this from https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/801778

Since Firefox 3.6.18, cookies cannot be stored with single character hostnames. This is reproducible by installing the extension developer addon and doing this in the JS shell:

cm = Cc["@mozilla.org/cookiemanager;1"].getService(Ci.nsICookieManager2);
expiry = (Date.now() + 1000) * 1000;
cm.countCookiesFromHost("a"); /* Should be 0 */
cm.add("a", "/", "foo", "bar", false, false, true, expiry);
cm.countCookiesFromHost("a"); /* Is still 0, but should now be 1 */

This wasn't a problem in 3.6.17. It doesn't seem to be a problem on current nightlies or aurora either (I didn't test 5.0)

I see there's a couple of suspect commits between 3.6.17 and 3.6.18, but I'm still waiting for my mozilla-1.9.2 tree to build before I can actually verify that:

It's definitely this one which breaks it: http://hg.mozilla.org/releases/mozilla-1.9.2/rev/bb935ffe5ff1

When running the first iteration of the loop in nsCookieService::CountCookiesFromHostInt, (nextDot <= end && *(nextDot + 1) == '\0') always evaluates to true, so it just bails out

Here is a patch which fixes this, with test-case. I'm not sure if it's the best way to fix this without understanding what http://hg.mozilla.org/releases/mozilla-1.9.2/rev/bb728fdcd717 is for.

apparently not a problem on trunk, where we took a different patch for bug 616264

The ubuntu folks want this badly.  Can we get the approval on this one soon, please?

I landed the m-c test on inbound.  Please do not mark the bug as FIXED when you merge to central.
