Pascal Wittmann 4921223160 Print license information on '--xml --meta'
The nixpkgs manual prescribes the use of values from stdenv.lib.licenses
for the meta.license attribute. Those values are attribute sets and
currently skipped when running nix-env with '--xml --meta'. This has the
consequence that also nixpkgs-lint will report missing licenses.

With this commit nix-env with '--xml --meta' will print all attributes
of an attribute set that are of type tString. For example the output for
the package nixpkgs.hello is

    <meta name="license" type="strings">
      <string type="url" value="http://spdx.org/licenses/GPL-3.0+" />
      <string type="shortName" value="gpl3Plus" />
      <string type="fullName" value="GNU General Public License v3.0 or later" />
      <string type="spdxId" value="GPL-3.0+" />
    </meta>

This commit fixes nixpkgs-lint, too.

Vladimír Čunát 42808fa281 nix-env --upgrade: show "downgrading" when doing so
It was strange to show "upgrading" when the version was getting lower.
This is left on "upgrading" when the versions are the same,
as I can't see any better wording.

Vladimír Čunát 64f9b511be nix-env --upgrade: avoid unexpected downgrades
Until now, if one explicitly installed a low-priority version,
nix-env --upgrade would downgrade it by default and even with --leq.
Let's never accept an upgrade with version not matching the upgradeType.
Additionally, let's never decrease the priority of an installed package;
you can use --install to force that.

Also refactor to use variable bestVersion instead of bestName,
as only version was used from it.

Eelco Dolstra b83801f8b3 Optimize small lists
The value pointers of lists with 1 or 2 elements are now stored in the
list value itself. In particular, this makes the "concatMap (x: if
cond then [(f x)] else [])" idiom cheaper.

Christian Theune 3d83188702 Enable lazy/sparse allocation of generation symlinks: avoid creating

Alternatively or additionally I propose a mode where only the *last* generation will be sparse.

Or to install a specific version of NixOS:

  $ nixos-rebuild switch -I nixpkgs=63def04891.tar.gz

Ricardo M. Correia 700c678c2e nix-env: Minor change to '--delete-generations Nd' semantics
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!

Eelco Dolstra 25386e5edc Fix passing meta attribute to buildenv.nix
Since the meta attributes were not sorted, attribute lookup could
fail, leading to package priorities and active flags not working
correctly.

Broken since 0f24400d90.

Eelco Dolstra 3fd01b171a Set up a minimal /dev in chroots
Not bind-mounting the /dev from the host also solves the problem with
/dev/shm being a symlink to something not in the chroot.

Eelco Dolstra 1aa19b24b2 Add a flag ‘--check’ to verify build determinism
The flag ‘--check’ to ‘nix-store -r’ or ‘nix-build’ will cause Nix to
redo the build of a derivation whose output paths are already valid.
If the new output differs from the original output, an error is
printed.  This makes it easier to test if a build is deterministic.
(Obviously this cannot catch all sources of non-determinism, but it
catches the most common one, namely the current time.)

For example:

  $ nix-build '<nixpkgs>' -A patchelf
  ...
  $ nix-build '<nixpkgs>' -A patchelf --check
  error: derivation `/nix/store/1ipvxsdnbhl1rw6siz6x92s7sc8nwkkb-patchelf-0.6' may not be deterministic: hash mismatch in output `/nix/store/4pc1dmw5xkwmc6q3gdc9i5nbjl4dkjpp-patchelf-0.6.drv'

The --check build fails if not all outputs are valid.  Thus the first
call to nix-build is necessary to ensure that all outputs are valid.

The current outputs are left untouched: the new outputs are either put
in a chroot or diverted to a different location in the store using
hash rewriting.
