Eelco Dolstra 3cd5fd8bb3 More efficient version of filterAttrs 2015-07-23 16:49:13 +02:00
Benjamin Staffin 4dd93dbf25 lib: Fix matchAttrs by importing builtins.length
Before:

    nix-repl> :l <nixpkgs>
    nix-repl> lib.matchAttrs { foo = "bar"; } { bar = "bas"; }
    error: undefined variable ‘length’ at "/home/benley/nix/nixpkgs/lib/attrsets.nix":317:10

After:

    nix-repl> :l <nixpkgs>
    nix-repl> lib.matchAttrs { foo = "bar"; } { bar = "bas"; }
    false

Eelco Dolstra 97220c973f Replace hasAttr/getAttr calls with the ? and . operators
For NixOS evaluation, this gives a ~21% reduction in the number of
values allocated and a ~4% speedup. It's also more readable.

Eelco Dolstra a8b693fef7 Remove backward-compatible implementations of some primops
Nixpkgs requires at least Nix 1.2 anyway, so these are now useless.

Eelco Dolstra 40913958a2 Keep position information for option declarations and definitions
Also, when an option definition fails to type-check, print the file
name of the module in which the offending definition occurs, e.g.

  error: user-thrown exception: The option value `boot.loader.grub.version' in `/etc/nixos/configuration.nix' is not a integer.
