lib.makeScope: Save package set function 2017-02-27 11:49:43 -06:00

9d55479e07 add .overrideDerivation and .overrideAttrs to packages created with callPackages/callPackagesWith
nix/nixUnstable, tomcatN and postgresqlNN use `callPackages` pattern, they have .override
attribute, but lack .overrideDerivation and recent .overrideAttrs.
Packages created with `callPackage` have all of those. Because .overrideDerivation function
is used in public, without this we can break code when refactoring callPackage -> callPackages.

~/.nixpkgs -> ~/.config/nixpkgs
The former is still respected as a fallback for config.nix for
backwards compatibility (but not for overlays because they're a new
feature).

39b64b52ed mkDerivation: add overrideAttrs function
This is similar to `overrideDerivation`, but overrides the arguments to
`mkDerivation` instead of the underlying `derivation` call.

Also update `makeOverridable` so that uses of `overrideAttrs` can be
followed by `override` and `overrideDerivation`, i.e. they can be
mix-and-matched.

ab8a691d05 nixos systemPackages: rework default outputs
- Now `pkg.outputUnspecified = true` but this attribute is missing in
  every output, so we can recognize whether the user chose or not.
  If (s)he didn't choose, we put `pkg.bin or pkg.out or pkg` into
  `systemPackages`.
- `outputsToLink` is replaced by `extraOutputsToLink`.
  We add extra outputs *regardless* of whether the user chose anything.
  It's mainly meant for outputs with docs and debug symbols.
- Note that as a result, some libraries will disappear from system path.

b89b6b2a7b Add function callPackagesWith
This is like callPackageWith, except that it expects the supplied
function to return a *set* of packages. It will then make the
individual packages overridable.

314e8e49ec Remove deepOverride
It's unused, and also a bad idea: because it recursively recomputes
every function argument and there is no sharing, you can get an
exponential (?) blowup in evaluation time. For example, evaluating
‘linuxPackages.kernel’ takes 0.09s and ~13 MiB, but evaluating
‘linuxPackages.kernel.deepOverride {}’ takes 3.6s and ~305 MiB.

0461f35894 Rename scrubDrv -> hydraJob and make it more effective
It now strictly evaluates all remaining attributes, preventing
unevaluated thunks that cannot be garbage-collected. It's also applied
to all jobs in Nixpkgs' release.nix.

This reduces hydra-eval-jobs' memory consumption on the 14.12
release-combined jobset from 5.1 GB to 2.0 GB.

hydra had, hydra has since been updated

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.
