Patch

This patch applies on top of patch attached to bug #126208. It's specific to soup because I don't know if mac needs to also notify the network process about user preferred languages change. Anders, could you confirm it?

Looking around, it seems that ephy-embed-prefs.c is GPL which is a big no-no. Maybe you can get Xan to relicense it since he seems to be the only copyright holder.

It's true that the code was copied from ephy and then adapted to wk coding style, but the original code in ephy (which is not part of ephy anymore since it's wk2 only) was copied from libsoup, that is LGPL. Dan, could you confirm that piece of code is LGPL? I'll update the comment (or just remove it) to avoid confusions.

Updated patch just removing the confusing comment

Removed the comment. The code is actually based on accept_languages_from_system() from libsoup, see:

https://git.gnome.org/browse/libsoup/tree/libsoup/soup-session.c?id=2.45.3#n390

[Dan Winship]

yeah, that code was copied into epiphany from libsoup, so it should be fine

Thanks for confirming it. I've moved that code to a common file in WebCore in another patch so that it's shared by web and network processes instead of having it duplicated. I'll submit a rebased patch.

Rebased patch

This is simpler patch now that doesn't need the build accept languages code.

Should be const Vector<String>&.
