In play.i18n.Lang, comment claims to be performing "country-only" match, but is in fact performing language match

Reported by Nebu | February 3rd, 2012 @ 07:18 PM | in 1.2.5 (closed)

Framework version: git commit dbb851d9b3e8c72ad0ab2356d74037468209a679
Platform you're using: Linux


The relevant code is in the resolvefrom method:

    // now see if we have a country-only match
    for (String a: request.acceptLanguage()) {
        if (a.indexOf("-") > 0) {
            a = a.substring(0, a.indexOf("-"));
        for (String locale: Play.langs) {
            if (locale.equals(a)) {

As can be seen by the parameters to substring, the code is looking at all the characters before the dash. However, if you look at the HTTP spec http://www.w3.org/Protocols/rfc2616/rfc2616-sec14.html the characters before the dash represent the language, whereas the characters after the dash represent the country.

Matching based on the language is the correct thing to do here, so the fix is just to update the comment to accurately reflect what the code is doing.

<h2>Creating a bug report</h2> Bug reports are incredibly helpful, so take time to report bugs and request features in our ticket tracker. We’re always grateful for patches to Play’s code. Indeed, bug reports with attached patches will get fixed far quickly than those without any.<br><br>

Don't have too much expectations. Unless the bug is really a serious "everything is broken" thing, you're creating a ticket to start a discussion. Having a patch (or a branch on Github we can pull from) is better, but then again we'll only pull high quality branches that make sense to be in the core of Play.
