Gnome 3.12

[lethalman]

I've updated gnome to 3.12 (in only 24 hours, awesome). I'm probably going to merge tomorrow if you don't see any problem at a first glance.
Noteworthy changes:

1. Moved gnome-3/* to gnome-3/3.10, and created gnome-3/3.12
2. New scope pkgs.gnome3_12.
3. New packages (not updates): cogl_1_18, clutter_1_18, upower_99, appdata-tools, spidermonkey_24.
4. Allow upower service to specify which upower package to use, gnome 3.12 will enforce upower 0.99.
5. Updates that should not break: geoclue 2.0.0 -> 2.1.8, json-glib 0.16.0 -> 1.0.0
6. New environment.gnome3.packageSet nixos option for specifying which gnome3 to use, e.g. pkgs.gnome3_12.
7. We are enforcing python3Packages = python33Packages due to #2693 and in general because python 3.3 is more stable for now.
8. Disabled gnome-terminal runtime migration from gconf to dconf, to drop the only gconf dependency.

Sweet!

I have a problem with this branch that seems related to some misunderstanding of newScope and merging of options on my side. Set this in the configuration.nix:

  services.xserver = {
    enable = true;
    displayManager.lightdm.enable = true;
    desktopManager.gnome3.enable = true;
  };

  environment.gnome3.packageSet = pkgs.gnome3_12;

With nixos-rebuild you get:

building the system configuration...
error: Package ‘python3.3-pyspotify-1.11’ in ‘/home/lethal/nixpkgs/pkgs/top-level/python-packages.nix:8920’ has an unfree license, refusing to evaluate. You can set
  { nixpkgs.config.allowUnfree = true; }
in configuration.nix to override this. If you use Nix standalone, you can add
  { allowUnfree = true; }
to ~/.nixpkgs/config.nix or pass
  --arg config '{ allowUnfree = true; }'
on the command line.
(use `--show-trace' to show detailed location information)

This is related to python3Packages = python33Packages; here: https://github.com/lethalman/nixpkgs/blob/08e46e4669686bf5cb2366b5e7ef1dd998885855/pkgs/desktops/gnome-3/3.12/default.nix#L12

In fact, setting python3Packages = python33Packages; in all-packages.nix does not raise this problem.

Also note that the closure of the drvs in nixos-rebuild dry-run when allowing unfree packages does not contain any reference to spotify.

Also note that nix-build of nixos/tests/gnome3_12.nix does not raise the problem either.

Are you sure your configuration doesn't refer to pyspotify or mopidy?

[lethalman]

@vcunat my nixos configuration? yes I'm sure. Also with gnome 3.10 there isn't this problem. I fear it must be some package using gnome 3.10 instead of the gnome 3.12 scope, but still I don't see why pyspotify gets evaluated.
Also there's no spotify when running nixos-rebuild dry-run with unfree enabled and printing the closure tree.

However this may clear up something. With this setup it still raises the error:

• Gnome 3.12 scope has no python override
• Gnome 3.10 has python3 = pkgs.python33Packages; and python = pkgs.python33;
• Use pkgs.gnome3_12 as gnome3 package set in nixos configuration.

That is, I've removed python override from gnome-3/3.12/default.nix and still gives the error. But removing it also from gnome-3/3.10 fixes the error.

So basically: the problem is in setting python3Packages = pkgs.python33Packages in gnome-3/3.10, even using gnome 3.10 for the xserver configuration. Gnome 3.12 has nothing to do with that.

Update: the problem arises also by disabling gnome, the xserver and everything in my nixos configuration. I fear it must be something wrong with the usage of the newScope in gnome3 together with python3Packages = python33Packages; .

[lethalman]

I've removed the python3Packages = python33Packages override, hoping in getting it fixed in all-packages :-)
