Huh, shouldn't this be a no-op? ofborg lists a bunch of derivations that seem to have changed

danbst · 2019-02-02T06:32:20Z

Same "huh" here, but it turned out pcre16 is different from res.pcre16 (and qt depends on pcre16)

so, res.pcre was a bootstrap package, but self.pcre is not. I think it is fine to merge this.

Ericson2314 · 2019-02-02T20:47:13Z

It's the other way around, res.pcre is not the bootstrap package. This is probably because stdenv overrides are applied after all-packages.nix, so res.pcre bypasses it. This change then has the side affect of avoiding a pointless rebuild of pcre.

Ericson2314 · 2019-02-02T20:48:41Z

@roberth I'd like to apologize to you for not so analyzing your PR like I said I would. I have had less time for Nixpkgs things lately but still I should follow up on anything I said I'd do.

roberth · 2019-02-03T10:40:30Z

@Ericson2314 no problem. It seems that there are plenty more important things to do, even when considering just Nixpkgs.

edit: Also seems to impact a few more tests (simple.nix, memcached.nix, etc.)

delroth · 2019-02-03T12:41:47Z

This seems to be caused by an interaction with overlays. In nixos/modules/config/no-x-libs.nix:

    nixpkgs.overlays = singleton (const (super: {
      pinentry = super.pinentry_ncurses;
    }));

danbst · 2019-02-03T13:32:06Z

@delroth crap. However this reveal many other ways when overlay override would cause infinite recursion. For example:

$ nix-instantiate -E 'with import <nixpkgs> { overlays = [(self: super: { 
    ttfautohint = self.ttfautohint-nox;
  })]; }; ttfautohint'
error: infinite recursion encountered, at /nix/store/94cbas4j0w0132qhxa5qn7zybrss3ymm-nixpkgs-19.03pre167327.11cf7d6e1ff/nixpkgs/pkgs/top-level/all-packages.nix:5926:21
(use '--show-trace' to show detailed location information)

$ nix-instantiate -E 'with import <nixpkgs> { overlays = [(self: super: { 
    ttfautohint = super.ttfautohint-nox;
  })]; }; ttfautohint'
error: infinite recursion encountered, at /nix/store/94cbas4j0w0132qhxa5qn7zybrss3ymm-nixpkgs-19.03pre167327.11cf7d6e1ff/nixpkgs/pkgs/top-level/all-packages.nix:5926:21
(use '--show-trace' to show detailed location information)

There should be some principal approach to fix this (never use .override in all-packages.nix?)

Should have read this commit first d1a2853

Ericson2314 · 2019-02-04T01:34:57Z

Yes If I understand the issue correctly that commit has a pretty bogus workaround. A good rule for the "overrides and default assignment problem" is to make a fooReal which is overriden instead. So pinentry_ncurses could instead override pinentryReal, which is never flat-out replaced in any overlay.

oxij · 2019-02-21T03:01:09Z

Another attempt #56119 by me.

Tested with nix-env -qaf . The res -> super changes are necessary because res points to the result of the current overlay, but some of the packages were moved to the previous overlay, which can be accessed with super. This is a fundamental problem to be fixed, see NixOS#55061 and related issues The schleuder change is necessary because the ./default.nix file referenced ./., but there's also another package in ./bin. The tool couldn't move the gemfiles in ./. because The schleuder change is necessary because the tool isn't smart enough and this is a special case of the default.nix reading gemfiles from a ./. reference and there being both schleuder in pkgs/tools/security/schleuder and schleuder-cli in pkgs/tools/security/schleuder/cli
