Nixpkgs: Difference between revisions

Line 2:

'''Nixpkgs''' is the largest repository of [[Nix]] packages and [[NixOS]] modules. The repository is [https://github.com/nixos/nixpkgs hosted on GitHub] and maintained by the community, with official backing from the [https://nixos.org NixOS Foundation].

== Channels ==

The packages and modules hosted on Nixpkgs are sorted in various channels intended for various use-cases, and in practice are differentiated by the level of testing updates must pass on the official [https://nixos.org/hydra/manual/#idm140737315980672 nixos.org hydra instance] and the number of updates propagated to the channel. For [[Nix]] users, <code>nixpkgs-unstable</code> is the bleeding-edge, where packages pass only basic build tests and are upgraded continuously; for [[NixOS]] users, <code>nixos-unstable</code> is the bleeding-edge, where packages pass build tests and integration tests on a VM. Both [[Nix]] and [[NixOS]] users can use stable channels - the latest being <code>nixos-17.09</code> - to receive only conservative updates for fixing critical bugs and security vulnerabilities. For more information see the [[Nix Channels]] article.

There can be multiple maintainers per package. Maintainers will receive emails from [[Hydra|Hydra]] when package builds enters a failed state. They do not have special privileges as everybody can suggest updates and modifications to any package. However they might be consulted by NixOS members for testing and as a domain experts, when somebody else make a change to a package.

~~== Channels ==~~

Channels in the Nix Ecosystem are tagged and tested revisions inside the Nixpkgs repository. Every push of code towards the repository will be built by the official [https://nixos.org/hydra/manual/#idm140737315980672 nixos.org hydra instance]. The [[Nix Channels]] article provides an overview of the official channels which are currently available.
