Eelco Dolstra e414bde6f9 Check the flake epoch 
Closes #2883.
 2019-05-22 14:31:40 +02:00
Eelco Dolstra 70136a9bf4 Move flake-related flags into a separate class 
Also, rename --dont-save-lock-file to --no-save-lock-file and change
noRegistries to useRegistries.
 2019-05-22 14:04:18 +02:00
Eelco Dolstra 2468672e30 Improve FlakeCommand 
It now handles commonality like calling getFlake() and resolving
relative local flake refs.

Fixes #2822.

Eelco Dolstra 20a1a65d37 Only rewrite the lockfile if it changed 
This removes spurious warnings about failure to write the lockfile.

lockfile updating

Eelco Dolstra 5c34d66538 Make flakes work with 'nix build --store ...' 
It was getting confused between logical and real store paths.

Also, make fetchGit and fetchMercurial update allowedPaths properly.

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

Fix assertion failure in FlakeRef::to_string() 
Fixes

  $ nix build
  nix: src/libexpr/primops/flakeref.cc:169: std::__cxx11::string nix::FlakeRef::to_string() const: Assertion `!rev' failed.
  Aborted

e.g. when flake.nix doesn't exist.

Also use gitRev().

Eelco Dolstra ddd42b7e94 Fix immutable flakeref construction 
We were appending ref/revs incorrectly for the IsGit case (by
appending /<ref>/<rev> rather than ?ref=<ref>&rev=<rev).
 2019-05-07 23:32:09 +02:00
Eelco Dolstra 2a41a567e2 Improve FlakeRef::to_string() 
We were incorrectly using path syntax (i.e. /<ref>/<rev>) for Git
repositories. This is only valid for GitHub flakerefs.

Eelco Dolstra 60834492ae Update lock files from InstallableFlake::toValue() 
This ensures that the lock file is updated *before* evaluating it, and
that it gets updated for any nix command, not just 'nix build'.

Also, while computing the lock file, allow arbitrary registry lookups,
not just at top-level.

Also, improve some error messages slightly.

Eelco Dolstra c996e04aca Allow relative paths in flakerefs 
Also allow "." as an installable to refer to the flake in the current

directory.

Eelco Dolstra 6a4c7fb975 Add path flakeref variant 
Unlike file://<path>, this allows the path to be a dirty Git tree, so

  nix build /path/to/flake:attr

is a convenient way to test building a local flake.
 2019-04-08 23:09:18 +02:00
Eelco Dolstra 154244adc6 nix: New installables syntax 
The general syntax for an installable is now
<flakeref>:<attrpath>. The attrpath is relative to the flake's
'provides.packages' or 'provides' if the former doesn't yield a
result. E.g.

  $ nix build nixpkgs:hello

is equivalent to

  $ nix build nixpkgs:packages.hello

Also, '<flakeref>:' can be omitted, in which case it defaults to
'nixpkgs', e.g.

  $ nix build hello

nix: Add --flake flag

Enforce use of immutable flakes in pure mode 
... plus a temporary hack to allow impure flakes at top-level for the
default installation source.
 2019-02-12 21:07:48 +01:00
Eelco Dolstra ba05f29838
nix: Enable pure mode by default 
We want to encourage a brave new world of hermetic evaluation for
source-level reproducibility, so flakes should not poke around in the
filesystem outside of their explicit dependencies.

Note that the default installation source remains impure in that it
can refer to mutable flakes, so "nix build nixpkgs.hello" still works
(and fetches the latest nixpkgs, unless it has been pinned by the
user).

A problem with pure evaluation is that builtins.currentSystem is
unavailable. For the moment, I've hard-coded "x86_64-linux" in the
nixpkgs flake. Eventually, "system" should be a flake function
argument.

Add github URIs 
For example, github:edolstra/dwarffs is more-or-less equivalent to
https://github.com/edolstra/dwarffs.git. It's a much faster way to get
GitHub repositories: it fetches tarballs rather than entire Git
repositories. It also allows fetching specific revisions by hash
without specifying a ref (e.g. a branch name):
