"Nix expression" on package search results links to wrong URLs

[das-g]

E.g., for bash on NixOS 19.09, it currently displays

Nix expression	/build/source/pkgs/shells/bash/4.4.nix

which links to https://github.com/NixOS/nixpkgs/blob/undefined//build/source/pkgs/shells/bash/4.4.nix#L110, which leads to a 404 "Page not found" error page.

It should probably be something like https://github.com/NixOS/nixpkgs/blob/nixos-19.09/pkgs/shells/bash/4.4.nix#L110 instead., i.e.

nixos-19.09

(or whatever the channel name of the search result is)

instead of

undefined//build/source

Um, now the website says

Nix expression	Not specified

Is that intended? Is it just a temporary artefact and the actual information will come back?

[edolstra]

Yes, it will be back once packages.json contains a commit field.

Yes, it will be back once packages.json contains a commit field.

When will that be?
Because the "Nix expression" links were quite useful.
