[Nix-dev] Dropped renameImports from buildGoPackage
The renameImports was a bad choice for buildGoPackage infrastructure. Every package would have to specify the needed renames. Now instead each library can define goPackageAliases, and dependant packages will automatically rename the imports. With renameImports: A depends on B - B changed goPackagePath - now A fails to build because it needs a renameImports. With goPackageAliases: A depends on B - B changes goPackagePath and adds goPackageAliases - now A correctly builds because the rename is done automatically.

[Nix-dev] Proposal: make global dependencies or paths explicit
There are a few dependencies in nixos that are hidden from nix as to not have to recompile the world when they change. The instances I know of are the timezone files and CA certificates but there's probably more. The timezone files expect TZDIR to be set, and all programs are being compiled to check /etc/ssl/certs/ca-bundle.crt. I would like to propose that all global state is kept at fixed paths (like it is with ca-bundle) but that all occurences of those paths are instead replaced with attributes of pkgs.config.statics, so that users can override them easily. That way, for other platforms (e.g. Darwin or cygwin) you can point those paths to where the relevant data is and ideally with a light recompile you'd have everything working. Basically, all occurrences of static paths in nixpkgs like /etc or /var should be replaced with pkgs.config.statics.zonedir, .ca-bundle, .system-config (configuration.nix), .nix-config (/etc/nix/nix.conf), .shell-profile (/etc/profile) etc. Should be a pretty small change, not resulting in many rebuilds, that allows for better discoverability and configurability. As an example benefit, we can now make /etc/ssl/certs/ca-certificates.crt the default instead of ca-bundle.crt, simply change one line. If we do this for everything, eventually this will for example allow us to move /etc/passwd and /etc/shadow elsewhere, and having full visibility into all builds that use it. I gave the concept a try in my static-paths branch at https://github.com/wmertens/nixpkgs/tree/static-paths but it's not working because for some reason the contents of nixpkgs.config varies throughout evaluation. Hints welcome. To try, clone that branch and run nix-build ./nixos/default.nix -A system -v. I added traces for the pkgs.config contents. Would be great to have feedback on the naming and other options over choosing the nixpkgs config as well. Cheers, Wout. ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
[Nix-dev] Haskell packages don't show up in nix-env -qa (was: Confused about packages)
Hi folks, Q 2. Why can't I find some packages that I would expect to find? I guess this would be because of haskellPackages missing recurseIntoAttrs. I can't see it in there and no haskell packages are shown for me on master. the lack of recurseIntoAttrs is intentional. We'd suffer a significant performance loss if nix-env were to traverse the Haskell package set, because 'haskellPackages' defines 8000+ entries! Right now, we have a total of $ nix-env -qa | wc -l 11353 entries in Nixpkgs. Haskell adds another $ nix-env -qa -A haskellPackages | wc -l 8061 and then there's also R: $ nix-env -qa -A rPackages | wc -l 6323 I would like those packages to be visible during nix-env -qa, but Nix is just not fast enough to cope (unless you're running it on a modern machine with a fast SSD). If anyone has a suggestion how to deal with that situation, then I'd be glad to hear it!

[Nix-dev] package foo is broken due to missing package bar errors in Haskell packages (was: nixos and haskell)
Hi Steven, There appears to be a problem with non-deterministic build output with GHC 7.10.1 though.unsusable. the information you got from [1] is a bit misleading, IMHO. It states: The non-deterministic output problem seems a bit worse [in GHC 7.10.x]. I am unaware of any evidence to suggest that this is true. We've had an inconsistent binary cache on hydra.nixos.org exactly *once* since we've switched to GHC 7.10.x. That is unpleasant, no doubt, but the issue is not at all specific to GHC 7.10.x. GHC 7.8.x produced exactly the same problems at a rate that (until now) seems about the same. When GHC 7.8.x was used with parallel building enabled -- like we currently do with GHC 7.10.x --, inconsistent builds occurred at least once every week! The problem was so bad that we switched the feature off, eventually, because it rendered our binary caches near unusable. Now, we haven't used GHC 7.10.x for a long time yet, and it's possible that all hell breaks loose a minute after I've posted this message, but based on the knowledge we have so far GHC 7.10.x is clearly more stable in that regard than 7.8.x ever was. In the light of this, the recommendation You might want to avoid GHC 7.10.x. from [1] seems premature, at best. From what I have seen so far, I believe GHC 7.10.x to be a better choice for users who are concerned about the non-determinism bug [2]. I don't know how to use 7.8.4 instead. Replace occurrences of haskellPackages.foo with haskell.packages.ghc784.foo in your Nix files. I've reconfigured NixOS with a single binary cache in an attempt to mitigate the non-determinism (but I'm not sure if that's all that's required). I'm using http://hydra.cryp.to. Yes, for users of Linux/x86_64, that is probably the way to go at the moment. More details can be found at [3].

[Nix-dev] Confused about packages
I'm new to NixOS, and I'm confused about the relation between packages, nix-env, and /etc/nixos/configuration.nix. In case it matters, I'm on nixos-unstable: [root@wombat9000:~]# nix-channel --list nixos https://nixos.org/channels/nixos-unstable Q 1. Why do some packages have version numbers, and some don't? Are the ones without version numbers some sort of virtual package? [amy@wombat9000:~]$ nix-env -qa | grep dzen2 dzen2-0.9.5 [amy@wombat9000:~]$ nix-env -qa | grep dmenu2 dmenu2 Q 2. Why can't I find some packages that I would expect to find? Are they hidden? For example, I have the following in my /etc/nixos/configuration.nix: environment.systemPackages = with pkgs; [ dmenu2 dzen2 haskellPackages.xmonad haskellPackages.xmonadContrib haskellPackages.xmonadExtras wget xsel ]; But if someone hadn't told me the names to put there, how could I have found the names of the packages?
