Replace Value type setters with mk* functions
Move clearValue inside Value

mkInt instead of setInt

mkBool instead of setBool

mkString instead of setString

mkPath instead of setPath

mkNull instead of setNull

mkAttrs instead of setAttrs

mkList instead of setList*

regnat bab1cda0e6 Use the hash modulo in the derivation outputs
Rather than storing the derivation outputs as `drvPath!outputName` internally,
store them as `drvHashModulo!outputName` (or `outputHash!outputName` for
fixed-output derivations).

This makes the storage slightly more opaque, but enables an earlier
cutoff in cases where a fixed-output dependency changes (but keeps the
same output hash) − same as what we already do for input-addressed
derivations.

stev 869c0321ff Alter "wanted:" to "specified:" in hash mismatch output
This makes it even clearer which of the two hashes was specified in the
nix files. Some may think that "wanted" and "got" is obvious, but:
"got" could mean "got in nix file" and "wanted" could mean "want to see in nix file".

Kevin Quick cb186f1e75
Use "?dir=..." portion of "registry add" local path specification.
The registry targets generally follow a URL formatting schema with
support for a query parameter of "?dir=subpath" to specify a sub-path
location below the URL root.

Alternatively, an absolute path can be specified.  This specification
mode accepts the query parameter but ignores/drops it.  It would
probably be better to either (a) disallow the query parameter for the
path form, or (b) recognize the query parameter and add to the path.

This patch implements (b) for consistency, and to make it easier for
tooling that might switch between a remote git reference and a local
path reference.

See also issue #4050.

Greg Hale a303c0b6dc Fetch commits from github/gitlab using Auth header
`nix flake info` calls the github 'commits' API, which requires
authorization when the repository is private. Currently this request
fails with a 404.

This commit adds an authorization header when calling the 'commits' API.
It also changes the way that the 'tarball' API authenticates, moving the
user's token from a query parameter into the Authorization header.

The query parameter method is recently deprecated and will be disallowed
in November 2020. Using them today triggers a warning email.

Griffin Smith 626200713b Pass all args when auto-calling a function with an ellipsis
The command line options --arg and --argstr that are used by a bunch of
CLI commands to pass arguments to top-level functions in files go
through the same code-path as auto-calling top-level functions with
their default arguments - this, however, was only passing the arguments
that were *explicitly* mentioned in the formals of the function - in the
case of an as-pattern with an ellipsis (eg args @ { ... }) extra passed
arguments would get omitted. This fixes that to instead pass *all*
specified auto args in the case that our function has an ellipsis.

This is a bit hacky. Ideally we would automatically re-evaluate the

Restore backwards-compat for current builtins.fetchGit
If a repo is dirty, it used to return a `rev` object with an "empty"
sha1 (0000000000000000000000000000000000000000). Please note that this
only applies for `builtins.fetchGit` and *not* for `builtins.fetchTree{
type = "git"; }`.

Merge legacy fetchGit-builtin with the generic fetchTree-function
The original idea was to implement a git-fetcher in Nix's core that
supports content hashes[1]. In #3549[2] it has been suggested to
actually use `fetchTree` for this since it's a fairly generic wrapper
over the new fetcher-API[3] and already supports content-hashes.

This patch implements a new git-fetcher based on `fetchTree` by
incorporating the following changes:

* Removed the original `fetchGit`-implementation and replaced it with an
  alias on the `fetchTree` implementation.

* Ensured that the `git`-fetcher from `libfetchers` always computes a
  content-hash and returns an "empty" revision on dirty trees (the
  latter one is needed to retain backwards-compatibility).

* The hash-mismatch error in the fetcher-API exits with code 102 as it
  usually happens whenever a hash-mismatch is detected by Nix.

* Removed the `flakes`-feature-flag: I didn't see a reason why this API
  is so tightly coupled to the flakes-API and at least `fetchGit` should
  remain usable without any feature-flags.

* It's only possible to specify a `narHash` for a `git`-tree if either a
  `ref` or a `rev` is given[4].

* It's now possible to specify an URL without a protocol. If it's missing,
  `file://` is automatically added as it was the case in the original
  `fetchGit`-implementation.

Eelco Dolstra 810b2c6a48 nix flake init: Add a '--template' flag
The initial contents of the flake is specified by the
'templates.<name>' or 'defaultTemplate' output of another flake. E.g.

  outputs = { self }: {

    templates = {

      nixos-container = {
        path = ./nixos-container;
        description = "An example of a NixOS container";
      };

    };

  };

allows

  $ nix flake init -t templates#nixos-container

Also add a command 'nix flake new', which is identical to 'nix flake
init' except that it initializes a specified directory rather than the
current directory.

Eelco Dolstra 950b46821f Remove TreeInfo
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.

Eelco Dolstra 462421d345 Backport libfetchers from the flakes branch
This provides a pluggable mechanism for defining new fetchers. It adds
a builtin function 'fetchTree' that generalizes existing fetchers like
'fetchGit', 'fetchMercurial' and 'fetchTarball'. 'fetchTree' takes a
set of attributes, e.g.

  fetchTree {
    type = "git";
    url = "https://example.org/repo.git";
    ref = "some-branch";
    rev = "abcdef...";
  }

The existing fetchers are just wrappers around this. Note that the
input attributes to fetchTree are the same as flake input
specifications and flake lock file entries.

All fetchers share a common cache stored in
~/.cache/nix/fetcher-cache-v1.sqlite. This replaces the ad hoc caching
mechanisms in fetchGit and download.cc (e.g. ~/.cache/nix/{tarballs,git-revs*}).

This also adds support for Git worktrees (c169ea5904).

Bjørn Forsman f686efeed4 fetchGit: fix submodule corner case by fetching all refs from cacheDir
Due to fetchGit not checking if rev is an ancestor of ref (there is even
a FIXME comment about it in the code), the cache repo might not have the
ref even though it has the rev. This doesn't matter when submodule =
false, but the submodule = true code blows up because it tries to fetch
the (missing) ref from the cache repo.

Fix this in the simplest way possible: fetch all refs from the local
cache repo when submodules = true.

Require shallow clones to be requested explicitly
If you do a fetchTree on a Git repository, whether the result contains
a revCount attribute should not depend on whether that repository
happens to be a shallow clone or not. That would complicate caching a
lot and would be semantically messy. So applying fetchTree/fetchGit to
a shallow repository is now an error unless you pass the attribute
'shallow = true'. If 'shallow = true', we don't return revCount, even
if the repository is not actually shallow.

Note that Nix itself is not doing shallow clones at the moment. But it
could do so as an optimisation if the user specifies 'shallow = true'.

Issue #2988.

Substitute flake inputs
This improves reproducibility and may be faster than fetching from the

dynamically generated tarballs).

Unfortunately this doesn't work for the top-level flake since even if
we know the NAR hash of the tree, we don't know the other tree
attributes such as revCount and lastModified.

Eelco Dolstra cc22cf662b Respect lock files of inputs + fine-grained lock file control
When computing a lock file, we now respect the lock files of flake
inputs. This is important for usability / reproducibility. For
example, the 'nixops' flake depends on the 'nixops-aws' and
'nixops-hetzner' repositories. So when the 'nixops' flake is used in
another flake, we want the versions of 'nixops-aws' and
'nixops-hetzner' locked by the the 'nixops' flake because those
presumably have been tested.

This can lead to a proliferation of versions of flakes like 'nixpkgs'
(since every flake's lock file could depend on a different version of
'nixpkgs'). This is not a major issue when using Nixpkgs overlays or
NixOS modules, since then the top-level flake composes those
overlays/modules into *its* version of Nixpkgs and all other versions
are ignored. Lock file computation has been made a bit more lazy so it
won't try to fetch all those versions of 'nixpkgs'.

However, in case it's necessary to minimize flake versions, there now
are two input attributes that allow this. First, you can copy an input
from another flake, as follows:

  inputs.nixpkgs.follows = "dwarffs/nixpkgs";

This states that the calling flake's 'nixpkgs' input shall be the same
as the 'nixpkgs' input of the 'dwarffs' input.

Second, you can override inputs of inputs:

  inputs.nixpkgs.url = github:edolstra/nixpkgs/<hash>;
  inputs.nixops.inputs.nixpkgs.url = github:edolstra/nixpkgs/<hash>;

or equivalently, using 'follows':

  inputs.nixpkgs.url = github:edolstra/nixpkgs/<hash>;
  inputs.nixops.inputs.nixpkgs.follows = "nixpkgs";

This states that the 'nixpkgs' input of the 'nixops' input shall be
the same as the calling flake's 'nixpkgs' input.

Finally, at '-v' Nix now prints the changes to the lock file, e.g.

  $ nix flake update ~/Misc/eelco-configurations/hagbard
  inputs of flake 'git+file:///home/eelco/Misc/eelco-configurations?subdir=hagbard' changed:
    updated 'nixpkgs': 'github:edolstra/nixpkgs/7845bf5f4b3013df1cf036e9c9c3a55a30331db9' -> 'github:edolstra/nixpkgs/03f3def66a104a221aac8b751eeb7075374848fd'
    removed 'nixops'
    removed 'nixops/nixops-aws'
    removed 'nixops/nixops-hetzner'
    removed 'nixops/nixpkgs'

Eelco Dolstra bbe97dff8b Make the Store API more type-safe
Most functions now take a StorePath argument rather than a Path (which
is just an alias for std::string). The StorePath constructor ensures
that the path is syntactically correct (i.e. it looks like
<store-dir>/<base32-hash>-<name>). Similarly, functions like
buildPaths() now take a StorePathWithOutputs, rather than abusing Path
by adding a '!<outputs>' suffix.

Note that the StorePath type is implemented in Rust. This involves
some hackery to allow Rust values to be used directly in C++, via a
helper type whose destructor calls the Rust type's drop()
function. The main issue is the dynamic nature of C++ move semantics:
after we have moved a Rust value, we should not call the drop function
on the original value. So when we move a value, we set the original
value to bitwise zero, and the destructor only calls drop() if the
value is not bitwise zero. This should be sufficient for most types.

Also lots of minor cleanups to the C++ API to make it more modern
(e.g. using std::optional and std::string_view in some places).

This is with the default stack size of 8 MiB.

Putting the object on the heap reduces stack usage to < 5 MiB.

Add experimental-features setting
Experimental features are now opt-in. There are currently two
experimental features: "nix-command" (which enables the "nix"
command), and "flakes" (which enables support for flakes). This will
allow us to merge experimental features more quickly, without
committing to supporting them indefinitely.

Typical usage:

Eelco Dolstra 0ab64729e9 Improve GitHub caching
In particular, when building a flake lock file, inputs like 'nixpkgs'

later https://api.github.com/repos/<owner>/<repo>/tarball/<rev>, even
though they produce the same result.

Git and GitHub now also share a cache that maps revs to a store path
and other info.

Some effort to minimize flake dependencies
For example, if the top-level flake depends on
"nixpkgs/release-19.03", and one of its dependencies depends on
"nixpkgs", then the latter will be mapped to "nixpkgs/release-19.03",
rather than whatever the default branch of "nixpkgs" is. Thus you get
only one "nixpkgs" dependency rather than two.

This currently only works in a breadth-first way, so the other way
around (i.e. if the top-level flake depends on "nixpkgs", and a
dependency depends on "nixpkgs/release-19.03") still results in two
"nixpkgs" dependencies.

Eelco Dolstra 30ccf4e52d Turn flake inputs into an attrset
Instead of a list, inputs are now an attrset like

  inputs = {
    nixpkgs.uri = github:NixOS/nixpkgs;
  };

If 'uri' is omitted, than the flake is a lookup in the flake registry, e.g.

  inputs = {
    nixpkgs = {};
  };

but in that case, you can also just omit the input altogether and
specify it as an argument to the 'outputs' function, as in

  outputs = { self, nixpkgs }: ...

This also gets rid of 'nonFlakeInputs', which are now just a special
kind of input that have a 'flake = false' attribute, e.g.

  inputs = {
    someRepo = {
      uri = github:example/repo;
      flake = false;
    };
  };

Eelco Dolstra 6644b6099b
Add flake evaluation cache
This exploits the hermetic nature of flake evaluation to speed up
repeated evaluations of a flake output attribute.

For example (doing 'nix build' on an already present package):

  $ time nix build nixpkgs:firefox

  real    0m1.497s
  user    0m1.160s
  sys     0m0.139s

  $ time nix build nixpkgs:firefox

  real    0m0.052s
  user    0m0.038s
  sys     0m0.007s

The cache is ~/.cache/nix/eval-cache-v1.sqlite, which has entries like

  INSERT INTO Attributes VALUES(
    X'92a907d4efe933af2a46959b082cdff176aa5bfeb47a98fabd234809a67ab195',
    'packages.firefox',
    1,
    '/nix/store/pbalzf8x19hckr8cwdv62rd6g0lqgc38-firefox-67.0.drv /nix/store/g6q0gx0v6xvdnizp8lrcw7c4gdkzana0-firefox-67.0 out');

where the hash 92a9... is a fingerprint over the flake store path and
the contents of the lockfile. Because flakes are evaluated in pure
mode, this uniquely identifies the evaluation result.

Make flake input fetching lazy
As long as the flake input is locked, it is now only fetched when it
is evaluated (e.g. "nixpkgs" is fetched when
"inputs.nixpkgs.<something>" is evaluated).

This required adding an "id" attribute to the members of "inputs" in
lockfiles, e.g.

  "inputs": {
    "nixpkgs/release-19.03": {
      "id": "nixpkgs",
      "inputs": {},

  }

because the flake ID needs to be known beforehand to construct the
"inputs" attrset.

Fixes #2913.

This is primarily useful for version string generation, where we need

fetching the entire history). The last commit timestamp OTOH can be
extracted from GitHub tarballs.

Eelco Dolstra 90fe1dfd2f Register flake source trees as GC roots
This ensures that flakes don't get garbage-collected, which is
important to get nix-channel-like behaviour.

For example, running

  $ nix build hydra:

will create a GC root

  ~/.cache/nix/flake-closures/hydra -> /nix/store/xarfiqcwa4w8r4qpz1a769xxs8c3phgn-flake-closure

where the contents/references of the linked file in the store are the
flake source trees used by the 'hydra' flake:

  /nix/store/n6d5f5lkpfjbmkyby0nlg8y1wbkmbc7i-source
  /nix/store/vbkg4zy1qd29fnhflsv9k2j9jnbqd5m2-source
  /nix/store/z46xni7d47s5wk694359mq9ay353ar94-source

Note that this in itself is not enough to allow offline use; the
fetcher for the flakeref (e.g. fetchGit or downloadCached) must not
fail if it cannot fetch the latest version of the file, so long as it
knows a cached version.

Issue #2868.

It was getting confused between logical and real store paths.

(Maybe the evaluator, rather than the caller of the evaluator, should
apply toRealPath(), but that's a bigger change.)
