arcnmx 466fd1439f check-meta.nix: fix checkMetaRecursively option
In specific cases, combining the `checkMeta` and `checkMetaRecursively`
config options would result in `error: infinite recursion encountered`

aszlig 8f98a6d39b check-meta: Add isHydraChannel
This is needed in order to mark a certain derivation containing a Nix
expression tarball to Hydra so that it is recognised as a channel.

When I first got an evaluation error due to using this meta attribute, I
was under the impression that nobody outside of Vuizvui[1] is using this
feature and that we don't have any occurrence of isHydraChannel in
Nixpkgs.

However, when working around[2] the issue I assumed that it's not
something that should be included in Nixpkgs because we're not using it
there.

It turned out that my assumption was wrong and we *do* use the attribute
in Nixpkgs, namely via releaseTools.channel, which is similar to what
we're doing in Vuizvui.

Since we already include a bunch of undocumented attributes in
metaTypes, it only makes sense to add isHydraChannel as well since it's
actually documented in the Hydra documentation[3].

stdenv/check-meta: add a "maintainerless" warning
This warning logs when a package has no maintainers. It will stay silent
if `meta.maintainers` is not set at all, only complaining when it is an
empty list. In the future a separate warning could be added to allow for
that stricter behavior. Or this warning could be changed.

stdenv/check-meta: turn validity.valid into a str
This will allow for adding more validity types in the future, such as a
warning type. (which is in the next commit in this series)

This is NOT a breaking change because validity.valid is never exposed
outside of `stdenv.mkDerivation`.

Ana Hobden acfddd576e stdenv: support mainProgram in meta
Support `mainProgram` as an attribute of `meta` for packages.

This is an attribute used by [`nix
run`](https://nixos.org/manual/nix/unstable/command-ref/new-cli/nix3-run.html#description)
to customize the main program of a package.

For example, `pkgs.neovim` provides a `/bin/nvim` executable which users
would (almost certainly) prefer `nix run` to execute instead of a
non-existing `/bin/neovim`.

meta: expose availability flags in derivation metadata
Currently it's not possible to determine the reason why a package is
unavailable without evaluating nixpkgs multiple times with different
settings. eg.

    nix-repl> :p android-studio.meta
    { available = false; broken = false; unfree = true; unsupported = true; ... }

The following snippet is an example that uses this information to query
the availability information of all packages in nixpkgs, giving an
overview of all the packages currently marked as broken, etc.

    { pkgs }:

    with import <nixpkgs/lib>;

    let

      mapPkgs =
        let mapPkgs' = path: f: mapAttrs (n: v:
          let result = builtins.tryEval (v ? meta); in
          if !result.success then {} else
          if isDerivation v then f (path ++ [n]) v else
          if isAttrs v && v.recurseForDerivations or false then mapPkgs' (path ++ [n]) f v else
          {}
        );
        in mapPkgs' [];

      getMeta = path: drv:
        if drv.meta ? available then
          let meta = {
            pkg = concatStringsSep "." path;
            inherit (drv.meta) broken unfree unsupported insecure;
          };
          in builtins.trace meta.pkg meta
          else {};

      metaToList = attrs: flatten (map (v: if v ? pkg then v else metaToList v) (attrValues attrs));

stdenv/check-meta: getEnv if the attribute is unset (#72376)
There were two issues:

* builtins.getEnv was called deep into the nixpkgs tree making it hard
  to discover. This is solved by moving the call into
  pkgs/top-level/impure.nix
* when the config was explicitly set by the user to false, it would
  still try and load the environment variable. This meant that it was
  not possible to guarantee the same outcome on two different systems.

Graham Bennett b12605563f Fix handling of lists in whitelistedLicenses and blacklistedLicenses
A package's meta.license can either be a single license or a list.  The
code to check config.whitelistedLicenses and config.blackListedLicenses
wasn't handling this, nor was the showLicense function.

stdenv: shorten evaluation errors when in Hydra
Hydra's page showing evaluation errors is about a mile long, showing
buckets of user-friendly errors, like this:

    in job ‘seyren.aarch64-linux’:
    Package ‘oraclejre-8u191’ in /nix/store/fa9zzkbljkvdavwzirkrr5irg25ymbjl-source/pkgs/development/compilers/oraclejdk/jdk-linux-base.nix:71 has an unfree license (‘unfree’), refusing to evaluate.

    a) For `nixos-rebuild` you can set
      { nixpkgs.config.allowUnfree = true; }
    in configuration.nix to override this.

    b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
      { allowUnfree = true; }
    to ~/.config/nixpkgs/config.nix.

    in job ‘jetbrains.webstorm.x86_64-linux’:
    Package ‘webstorm-2018.3.1’ in /nix/store/fa9zzkbljkvdavwzirkrr5irg25ymbjl-source/pkgs/applications/editors/jetbrains/default.nix:230 has an unfree license (‘unfree’), refusing to evaluate.

    a) For `nixos-rebuild` you can set
      { nixpkgs.config.allowUnfree = true; }
    in configuration.nix to override this.

    b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
      { allowUnfree = true; }
    to ~/.config/nixpkgs/config.nix.

This makes it extremely hard to find actual issues in the output. This
patch set makes the output much more condensed in Hydra:

    Failed to evaluate nifticlib-2.0.0: «unsupported»: is not supported on ‘x86_64-apple-darwin’

meta.tests: rename into passthru.tests
Nix currently rejects derivations in `meta` values. This works around
that limitation by using `passthru` instead.

tests: split into a separate all-tests.nix file
This will make the list much easier to re-use, eg. for `nixosTests`

The drawback is that this approaches makes the
```
nix-build release.nix -A tests.opensmtpd.x86_64-linux
```
command about twice as slow (3s to 6s): it now has to evaluate `nixpkgs`
once for each architecture, instead of just having the hardcoded list of
tests that allowed to say “ok just evaluate for x86_64-linux”.

On the other hand, complete evaluation of `release.nix` should be much
faster because we no longer import `nixpkgs` for each test: testing with
the following command went from 30s to 18s, and that's just for a few
tests.
```
time nix-instantiate --eval --strict nixos/release.nix -A tests.nat
```
I initially wanted to test on the whole `release.nix`, but there are too
many broken tests and it takes too long to eval them all, especially
compared to the fact that the current implementation breaks some setup.

Given developers can just `nix-build nixos/tests/my-test.nix`, it sounds
like an overall win.

dovecot, opensmtpd: add link to test in meta.tests
Rationale
---------

Currently, tests are hard to discover. For instance, someone updating
`dovecot` might not notice that the interaction of `dovecot` with
`opensmtpd` is handled in the `opensmtpd.nix` test.

And even for someone updating `opensmtpd`, it requires manual work to go
check in `nixos/tests` whether there is actually a test, especially
given not so many packages in `nixpkgs` have tests and this is thus most
of the time useless.

Finally, for the reviewer, it is much easier to check that the “Tested
via one or more NixOS test(s)” has been checked if the file modified
already includes the list of relevant tests.

Implementation
--------------

Currently, this commit only adds the metadata in the package. Each
element of the `meta.tests` attribute is a derivation that, when it
builds successfully, means the test has passed (ie. following the same
convention as NixOS tests).

Future Work
-----------

In the future, the tools could be made aware of this `meta.tests`
attribute, and for instance a `--with-tests` could be added to
`nix-build` so that it also builds all the tests. Or a `--without-tests`
to build without all the tests. @Profpatsch described in his NixCon talk
such systems.

Another thing that would help in the future would be the possibility to
reasonably easily have cross-derivation nix tests without the whole
NixOS VM stack. @7c6f434c already proposed such a system.

This RFC currently handles none of these concerns. Only the addition of
`meta.tests` as metadata to be used by maintainers to remember to run
relevant tests.

Benjamin Hipple 0b9d9ab256 Remove dead code from stdenv check-meta license logic
The `unfree` and `unfreeRedistributable` licenses both have `free = false`,
which will trigger the first portion of logic. This removes dead code to
simplify the logic.

As a follow-up, I plan to add an attribute `redistributable = [true|false]`,
which can be used by Hydra to determine whether a given package with a given
license can be included in the channel.

stdenv: Validate meta.outputsToInstall
If meta.outputsToInstall is set to include absent outputs, various
tools break including channel updates and nix-env.

    grahamc@Morbo> nix-env -i -f . -A elf-header-real
    installing 'elf-header'
    error: this derivation has bad 'meta.outputsToInstall'

This patch verifies each value in meta.outputsToInstall is a valid
output. It validates this condition only if checkMeta is true.

    grahamc@Morbo> nix-build . -A elf-header-real
    error: Package ‘elf-header’ in /home/grahamc/projects/nixpkgs/pkgs/development/libraries/elf-header/default.nix:36 has invalid meta.outputsToInstall, refusing to evaluate.

    The package elf-header has set meta.outputsToInstall to: bin

    however elf-header only has the outputs: out

    and is missing the following ouputs:

      - bin

    (use '--show-trace' to show detailed location information)

Note, now the nix-env experience is decidedly worse for users who have
checkMeta set to true:

    grahamc@Morbo> nix-env -i -f . -A elf-header-real; echo $?
    0

though since this is already an issue for unfree, broken, unsupported,
and insecure validity problems I'm not sure we should do something
different here.
