2014-05-26 Add constant ‘nixPath’Eelco Dolstra3-2/+20
It contains the Nix expression search path as a list of { prefix, path } sets, e.g. [ { path = "/nix/var/nix/profiles/per-user/root/channels/nixos"; prefix = ""; } { path = "/etc/nixos/configuration.nix"; prefix = "nixos-config"; } { path = "/home/eelco/Dev/nix/inst/share/nix/corepkgs"; prefix = "nix"; } ]
2014-05-26 Add primop ‘scopedImport’Eelco Dolstra8-3/+50
‘scopedImport’ works like ‘import’, except that it takes a set of attributes to be added to the lexical scope of the expression, essentially extending or overriding the builtin variables. For instance, the expression scopedImport { x = 1; } ./foo.nix where foo.nix contains ‘x’, will evaluate to 1. This has a few applications: * It allows getting rid of function argument specifications in package expressions. For instance, a package expression like: { stdenv, fetchurl, libfoo }: stdenv.mkDerivation { ... buildInputs = [ libfoo ]; } can now we written as just stdenv.mkDerivation { ... buildInputs = [ libfoo ]; } and imported in all-packages.nix as: bar = scopedImport pkgs ./bar.nix; So whereas we once had dependencies listed in three places (buildInputs, the function, and the call site), they now only need to appear in one place. * It allows overriding builtin functions. For instance, to trace all calls to ‘map’: let overrides = { map = f: xs: builtins.trace "map called!" (map f xs); # Ensure that our override gets propagated by calls to # import/scopedImport. import = fn: scopedImport overrides fn; scopedImport = attrs: fn: scopedImport (overrides // attrs) fn; # Also update ‘builtins’. builtins = builtins // overrides; }; in scopedImport overrides ./bla.nix * Similarly, it allows extending the set of builtin functions. For instance, during Nixpkgs/NixOS evaluation, the Nixpkgs library functions could be added to the default scope. There is a downside: calls to scopedImport are not memoized, unlike import. So importing a file multiple times leads to multiple parsings / evaluations. It would be possible to construct the AST only once, but that would require careful handling of variables/environments.

2014-05-21 nix-store -l: Fetch build logs from the InternetEelco Dolstra9-93/+144
If a build log is not available locally, then ‘nix-store -l’ will now try to download it from the servers listed in the ‘log-servers’ option in nix.conf. For instance, if you have: log-servers = http://hydra.nixos.org/log then it will try to get logs from http://hydra.nixos.org/log/<base name of the store path>. So you can do things like: $ nix-store -l $(which xterm) and get a log even if xterm wasn't built locally.

2014-05-15 Shortcut store files before lstatWout Mertens2-9/+37
readdir() already returns the inode numbers, so we don't need to call lstat to know if a file was already linked or not.

2014-05-13 Preload linked hashes to speed up lookupsWout Mertens2-10/+41
By preloading all inodes in the /nix/store/.links directory, we can quickly determine of a hardlinked file was already linked to the hashed links. This is tolerant of removing the .links directory, it will simply recalculate all hashes in the store.

2014-05-10 Shortcut already-hardlinked fileswmertens1-1/+10
If an inode in the Nix store has more than 1 link, it probably means that it was linked into .links/ by us. If so, skip. There's a possibility that something else hardlinked the file, so it would be nice to be able to override this. Also, by looking at the number of hardlinks for each of the files in .links/, you can get deduplication numbers and space savings.

This automatically creates /nix/var/nix/profiles/per-user and sets the permissions/ownership on /nix/store to 1775 and root:nixbld.

2014-04-15 nix-env: Minor change to '--delete-generations Nd' semanticsRicardo M. Correia3-7/+15
The option '--delete-generations Nd' deletes all generations older than N days. However, most likely the user does not want to delete the generation that was active N days ago. For example, say that you have these 3 generations: 1: <30 days ago> 2: <15 days ago> 3: <1 hour ago> If you do --delete-generations 7d (say, as part of a cron job), most likely you still want to keep generation 2, i.e. the generation that was active 7 days ago (and for most of the past 7 days, in fact). This patch fixes this issue. Note that this also affects 'nix-collect-garbage --delete-older-than Nd'. Thanks to @roconnor for noticing the issue!
