In Nix, each string has a context that it carries of where it
originated. Some functions like filterAttrs modify the context of its
args when doing comparisons. That is important because we use the
string context of “name” to get where a derivation was defined. This
causes some builtins like unsafeGetAttrPos to report incorrectly that
the string was set in lib/attrsets.nix and reporting that as the
source file. Using removeAttrs avoids this problem.
Fixes #63679
(cherry picked from commit 1f46aaab1b)
The web list of packages shows the current stable branch, so we needed
to backport this to fix that effect soonish. The change itself seems
very safe; only one rebuild is detected: `common-updater-scripts`
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 https://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-19.03 for the latest
release and nixos-unstable for the latest successful build of master:
% git remote update channels
% git rebase channels/nixos-19.03
For pull requests, please rebase onto nixpkgs master.
NixOS Linux distribution source code is located inside
nixos/ folder.
