This was useful for an experiment with building Nix as a single compilation unit. It's not very useful otherwise but also doesn't hurt...

2020-05-30Remove TreeInfoEelco Dolstra
The attributes previously stored in TreeInfo (narHash, revCount, lastModified) are now stored in Input. This makes it less arbitrary what attributes are stored where. As a result, the lock file format has changed. An entry like "info": { "lastModified": 1585405475, "narHash": "sha256-bESW0n4KgPmZ0luxvwJ+UyATrC6iIltVCsGdLiphVeE=" }, "locked": { "owner": "NixOS", "repo": "nixpkgs", "rev": "b88ff468e9850410070d4e0ccd68c7011f15b2be", "type": "github" }, is now stored as "locked": { "owner": "NixOS", "repo": "nixpkgs", "rev": "b88ff468e9850410070d4e0ccd68c7011f15b2be", "type": "github", "lastModified": 1585405475, "narHash": "sha256-bESW0n4KgPmZ0luxvwJ+UyATrC6iIltVCsGdLiphVeE=" }, The 'Input' class is now a dumb set of attributes. All the fetcher implementations subclass InputScheme, not Input. This simplifies the API. Also, fix substitution of flake inputs. This was broken since lazy flake fetching started using fetchTree internally.
2020-04-27Improve path:// handlingEelco Dolstra
In particular, doing 'nix build /path/to/dir' now works if /path/to/dir is not a Git tree (it only has to contain a flake.nix file). Also, 'nix flake init' no longer requires a Git tree (but it will do a 'git add flake.nix' if it's a Git tree)

2020-04-07Add 'path' fetcherEelco Dolstra
This fetchers copies a plain directory (i.e. not a Git/Mercurial repository) to the store (or does nothing if the path is already a store path). One use case is to pin the 'nixpkgs' flake used to build the current NixOS system, and prevent it from being garbage-collected, via a system registry entry like this: { "from": { "id": "nixpkgs", "type": "indirect" }, "to": { "type": "path", "path": "/nix/store/rralhl3wj4rdwzjn16g7d93mibvlr521-source", "lastModified": 1585388205, "rev": "b0c285807d6a9f1b7562ec417c24fa1a30ecc31a" }, "exact": true } Note the fake "lastModified" and "rev" attributes that ensure that the flake gives the same evaluation results as the corresponding Git/GitHub inputs.
