4 far-reaching changes: Smaller PATH, New vars, different propagation logic, and different hook logic Smaller PATH ------------ `buildInputs` no longer go on the PATH at build time, as they cannot be run when cross compiling and we don't want to special case. Simply make a `nativeBuildInput` too if one needs them on the PATH. Fixes #21191. Many new depedendency variables ------------------------------- See the stdenv chapter of the nixpkgs manual. I pulled out the existing documentation of dependency specification into a new section, and added language for these two (and their propagated equivalents) along side the others'. More complex propagation logic ------------------------------ Before a propagated*XXX*Input always acted as if it was specified directly as a *XXX*Input downstream. That's simple enough, but violates the intended roles of each sort of dep, which has functional and not just stylistic consequences. The new algorithm is detailed in the manual, and ensures everything ends up in the right place. I tried to give both an informal and formal description, but I suspect in practice it will not make much sense until one tries cross compiling, after which it will immediately make sense as the only sane option. Simplified hook logic --------------------- Rather than `envHook` and `crossEnvHook`, whose behavior differs depending on whether we are cross compiling or not, there is now one hook per sort (or rather non-propagated and propagated pair of sorts) of dependency. These new hooks have the same meaning regardless of cross compilation. See the setup hook section of stdenv chapter of the Nixpkgs manual for more details. |

Nixpkgs is a collection of packages for the Nix package manager. It is periodically built and tested by the Hydra build daemon as so-called channels. To get channel information via git, add nixpkgs-channels as a remote:
% git remote add channels git://github.com/NixOS/nixpkgs-channels.git
For stability and maximum binary package support, it is recommended to maintain
custom changes on top of one of the channels, e.g. nixos-17.09 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-17.09
For pull-requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
