2020-03-17	Unified fetcher caching system	Eelco Dolstra

2020-01-21	Convert fetchMercurial to a input type	Eelco Dolstra
	This enables Mercurial flakes. It also fixes a bug in pure mode where you could use a branch/tag name rather than a revision.
2019-11-27	nix: Add --expr flag	Eelco Dolstra
	This replaces the '(...)' installable syntax, which is not very discoverable. The downside is that you can't have multiple expressions or mix expressions and other installables.
2019-04-08	nix: Add --impure as a shorter alias of --no-pure-eval	Eelco Dolstra

2019-04-08	Fix tests	Eelco Dolstra

2018-01-16	Add pure evaluation mode	Eelco Dolstra
	In this mode, the following restrictions apply: * The builtins currentTime, currentSystem and storePath throw an error. * $NIX_PATH and -I are ignored. * fetchGit and fetchMercurial require a revision hash. * fetchurl and fetchTarball require a sha256 attribute. * No file system access is allowed outside of the paths returned by fetch{Git,Mercurial,url,Tarball}. Thus 'nix build -f ./foo.nix' is not allowed. Thus, the evaluation result is completely reproducible from the command line arguments. E.g. nix build --pure-eval '( let nix = fetchGit { url = https://github.com/NixOS/nixpkgs.git; rev = "9c927de4b179a6dd210dd88d34bda8af4b575680"; }; nixpkgs = fetchGit { url = https://github.com/NixOS/nixpkgs.git; ref = "release-17.09"; rev = "66b4de79e3841530e6d9c6baf98702aa1f7124e4"; }; in (import (nix + "/release.nix") { inherit nix nixpkgs; }).build.x86_64-linux )' The goal is to enable completely reproducible and traceable evaluation. For example, a NixOS configuration could be fully described by a single Git commit hash. 'nixos-rebuild' would do something like nix build --pure-eval '( (import (fetchGit { url = file:///my-nixos-config; rev = "..."; })).system ') where the Git repository /my-nixos-config would use further fetchGit calls or Git externals to fetch Nixpkgs and whatever other dependencies it has. Either way, the commit hash would uniquely identify the NixOS configuration and allow it to reproduced.
2017-11-21	fetchGit/fetchMercurial: Fix directory inclusion check	Eelco Dolstra
	E.g. the existence of .gitignore would cause .git to be included.
2017-11-07	Show when tests are skipped	Eelco Dolstra
	Also, don't depend on tput (ncurses). It's really not needed since ANSI escape sequences have been standardized for 35 years or so.
2017-11-03	fetchGit/fetchMercurial: Filter out directories with untracked files	Eelco Dolstra

2017-11-03	fetchGit: Add a test	Eelco Dolstra

2017-11-01	fetchMercurial: Don't fetch hashes we already have	Eelco Dolstra

2017-11-01	Add fetchMercurial primop	Eelco Dolstra
	E.g. $ nix eval '(fetchMercurial https://www.mercurial-scm.org/repo/hello)' { branch = "default"; outPath = "/nix/store/alvb9y1kfz42bjishqmyy3pphnrh1pfa-source"; rev = "82e55d328c8ca4ee16520036c0aaace03a5beb65"; revCount = 1; shortRev = "82e55d328c8c"; } $ nix eval '(fetchMercurial { url = https://www.mercurial-scm.org/repo/hello; rev = "0a04b987be5ae354b710cefeba0e2d9de7ad41a9"; })' { branch = "default"; outPath = "/nix/store/alvb9y1kfz42bjishqmyy3pphnrh1pfa-source"; rev = "0a04b987be5ae354b710cefeba0e2d9de7ad41a9"; revCount = 0; shortRev = "0a04b987be5a"; } $ nix eval '(fetchMercurial /tmp/unclean-hg-tree)' { branch = "default"; outPath = "/nix/store/cm750cdw1x8wfpm3jq7mz09r30l9r024-source"; rev = "0000000000000000000000000000000000000000"; revCount = 0; shortRev = "000000000000"; }
