Re: [Nix-dev] Improve docs for overrideDerivation - overridable attributes

[Alex Berg]

Oh wow! I never would have guessed this was a behavior of the `rec`
keyword! Nice idea!
I'll play around with it to verify my understanding and then submit a PR to
the NixPkgs manual to note this behavior for other people who might
discover this pitfall. That'll take me several days. :)

Much appreciated, Layus!

[Nix-dev] (setcap-wrapper) Building a nixos vm to test nixos-level modifications

[Parnell Springmeyer]

Hi! I recently added setcap-wrapper functionality to nixos at awake
networks and I have contributed the changes in a fork on my own branch.

My ask is: I'm having trouble figuring out how I should test this. Building
a package is easy but is there a formula some where for building a nixos VM
to test the setcap-wrapper functionality and my own modifications to take
ping and ping6 out of the setuid and use setcap instead?

Correct:

https://github.com/NixOS/nixpkgs/blob/master/pkgs/os-specific/linux/kernel/manual-config.nix#L91-97

Digression, I wish:

* Someone brave send /usr/bin/$PROG => /usr/bin/env $PROG patches
upstream (assuming it doesn't hurt anyone)
* NixOS chroot builds to have /usr/bin/env. Having to patch perfectly
portable code to perform a build doesn't feel right IMHO.

[Nix-dev] How does the kernel get build? Because /usr/bin/perl is hardcoded in the kernel sources...

[Matthias Beyer]

Hi nixos community,

I wonder how the kernel is build with nix, as /usr/bin/perl is 
hardcoded in all scripts in the kernel source tree.

Can someone point me to the appropriate file for how the build setup 
handles the kernel perl build infrastructure?

I assume our setup somehow rewrites the shebang lines of all these 
files before invoking the build... but I'm not sure here. Maybe 
someone can point this out to me.

Well... almost. Building went fine, but when switching to the new configuration:

$ sudo nixos-rebuild switch
...
building the system configuration...
updating GRUB 2 menu...
Can't exec "systemd-escape": No such file or directory at
/nix/var/nix/profiles/system/bin/switch-to-configuration line 264.

I'll try to make a PR to lock down that call systemd-escape with an

My first attempt was to override the derivation and simply set the 
"version" attribute, like this:


{
  packageOverrides = pkgs: rec {
vim = pkgs.vim.overrideDerivation (oldAttrs: {
  version = "7.4.1941";

}

But this had zero effect on the name of Vim I saw when using "nix-env 
-qaP" to see package details. The Vim package's definition has the 
"name" attribute defined like this:


name = "vim-${version}";
version = "7.4.1585";

so I expected my overriding the "version" attribute to affect the 
package's name, but it did not.
No, because the definition above relies on the "rec" keyword, but "rec" 
has already been applied /before/ overrideDerivation.
Overriding "version" will not override "name", and in turn will not 
override "src".
In fact, overriding "version" will have no impact on the output path as 
that parameter is not used by mkDerivation.
But the attribute is overriden. ` nix-instantiate "" --eval -A 
vim.version ` will give you the new version string.


Overriding "name", for example, will have impact as it is used by 
mkDerivation to compute the output path.

Again, it is not sufficient to build a different version of vim. See below.



After asking the #nixos IRC channel, one person suggested the 
"version" attribute isn't overridable because it isn't an attribute 
the *primitive derivation* set. Based on this guess, I changed my 
~/.nixpkgs/config.nix definition from that to this:


let
  vim-version = "7.4.1941";
in
{
  packageOverrides = pkgs: rec {
vim = pkgs.vim.overrideDerivation (oldAttrs: {
  name = "vim-${vim-version}";
  src = pkgs.fetchFromGitHub {
owner = "vim";
repo = "vim";
rev = "v${vim-version}";
sha256 = "0apq7sv1fbyfzqh4q0r2z19bn4gbjlb97wyl80kj7qsqmsy7m1lm";
  };
});
  };
}

My guess is this works because I'm overriding the "name" attribute.

No, it works because you override the "src" attribute.
src is used by mkDerivation, so overriding modifies the package to be 
built with the new source tree.
Overriding the name is not strictly necessary, but is a *very* good 
practice, as otherwise you would get a 7.4.1941 vim with the old version 
in the name... confusing :-)



I read the definition of the "mkDerivation" function 
(pkgs/stdenv/generic/default.nix), but it doesn't have a simple list 
of attributes that are overridable, but is rather flexible. Also, that 
definition doesn't mention a "src" attribute, but "src" attribute is 
overridable, so I wonder why overriding the "src" attribute works.


Where can I find explanation for this? If there is a restriction on 
which attributes are overridable, then I'd like to note this in the 
NixPkgs manual, here: 
https://nixos.org/nixpkgs/manual/index.html#sec-pkg-overrideDerivation
Everything is overridable separately, but you cannot count on the rec 
keyword at override time.

Every attribute already has a fully defined value.

[Nix-dev] Improve docs for overrideDerivation - overridable attributes

[Alex Berg]

I created a new "~/.nixpkgs/config.nix" file to customize the
nix-channel-obtained nixpkgs copy on my system - my goal was to bump the
version of Vim to a specific version.

My first attempt was to override the derivation and simply set the
"version" attribute, like this:

{
  packageOverrides = pkgs: rec {
vim = pkgs.vim.overrideDerivation (oldAttrs: {
  version = "7.4.1941";
});
  };
}

But this had zero effect on the name of Vim I saw when using "nix-env -qaP"
to see package details. The Vim package's definition has the "name"
attribute defined like this:

name = "vim-${version}";
version = "7.4.1585";

so I expected my overriding the "version" attribute to affect the package's
name, but it did not.

After asking the #nixos IRC channel, one person suggested the "version"
attribute isn't overridable because it isn't an attribute the *primitive
derivation* set. Based on this guess, I changed my ~/.nixpkgs/config.nix
definition from that to this:

let
  vim-version = "7.4.1941";
in
{
  packageOverrides = pkgs: rec {
vim = pkgs.vim.overrideDerivation (oldAttrs: {
  name = "vim-${vim-version}";
  src = pkgs.fetchFromGitHub {
owner = "vim";
repo = "vim";
rev = "v${vim-version}";
sha256 = "0apq7sv1fbyfzqh4q0r2z19bn4gbjlb97wyl80kj7qsqmsy7m1lm";
  };
});
  };
}

My guess is this works because I'm overriding the "name" attribute.

I tried going back a few releases. But at NixOS 13.10, which required
Nix 1.7 (still greater than my installed Nix 1.5.3), I decided not to

Thanks. This worked:

  nix-store --realize /nix/store/path-to-nix-11.2-found-on-hydra
  nix-env -i /nix/store/path-to-nix-11.2-found-on-hydra
  sudo nixos-rebuild switch

Re: [Nix-dev] How to upgrade when Nix is too old to evaluate nixpkgs

[Domen Kožar]

Could be, not sure at what verison it was added, but I think around first
NixOS release. You could try going with 13.10 first and then upgrade to
16.03

Did you try running switch? It should know how to upgrade Nix.

[Nix-dev] How to upgrade when Nix is too old to evaluate nixpkgs

[Bjørn Forsman]

Hi all,

I picked up an old NixOS installation from 2013, with nix 1.5.3. I
tried to upgrade to NixOS 16.03:

  $ nixos-rebuild build
  ...
  error: evaluation aborted with the following error message: `This
version of Nixpkgs requires Nix >= 1.10, please upgrade! See
https://nixos.org/wiki/How_to_update_when_Nix_is_too_old_to_evaluate_Nixpkgs'

The wiki page suggests to download something from hydra that now
yields a 404 error. I know the wiki is in read-only mode and NixOS
documentation generally needs work, so I check hydra myself to find
the correct URL:

  http://hydra.nixos.org/build/37216316

The problem is that none of the build artifacts can be downloaded!
Every URL return a 404 error saying:

  Path /nix/store/hmd2dzzsfan51snxgfy3ngmid5rvf08s-nix-1.11.2-debug is
no longer available.

(Going to builds a few weeks/months back gives the same error, just a
different hash.)

Suggestions?

Best regards,
Bjørn Forsman

[Maarten Hoogendoorn]

I only learned a few weeks ago that the wiki is not maintained anymore, and
that the content is going to be moved into the manuals.

Could we add a banner to the top of the wiki to tell (new) users that the
information in there might be out of date?

This might prevent a lot of frustration for new users.
