Dominik Xaver Hörl 25bef2d8f9 treewide: simplify pkgs.stdenv.lib -> pkgs.lib
The library does not depend on stdenv, that `stdenv` exposes `lib` is
an artifact of the ancient origins of nixpkgs.

nixos/hydra: remove hydra-migration upgrade path
This should NOT be backported to 20.09!

When 21.03 is released, the DB changes are about a year old and
operators had two release cycles for the upgrade. At this point it
should be fair to remove the compat layer to reduce the complexity of
the module itself.

nixos/tests/hydra*: fix eval
To specify distributed build-machines, `nix.distributedBuilds` must be
set to `true` now[1].

hydra: 2020-03-24 -> 2020-04-07
Also removed `pkgs.hydra-flakes` since flake-support has been merged
into master[1]. Because of that, `pkgs.hydra-unstable` is now compiled
against `pkgs.nixFlakes` and currently requires a patch since Hydra's
master doesn't compile[2] atm.

hydra: 2020-02-06 -> 2020-03-{24,27}
Upgrades Hydra to the latest master/flake branch. To perform this
upgrade, it's needed to do a non-trivial db-migration which provides a
massive performance-improvement[1].

The basic ideas behind multi-step upgrades of services between NixOS versions
have been gathered already[2]. For further context it's recommended to
read this first.

Basically, the following steps are needed:

* Upgrade to a non-breaking version of Hydra with the db-changes
  (columns are still nullable here). If `system.stateVersion` is set to
  something older than 20.03, the package will be selected
  automatically, otherwise `pkgs.hydra-migration` needs to be used.

* Run `hydra-backfill-ids` on the server.

* Deploy either `pkgs.hydra-unstable` (for Hydra master) or
  `pkgs.hydra-flakes` (for flakes-support) to activate the optimization.

The steps are also documented in the release-notes and in the module
using `warnings`.

`pkgs.hydra` has been removed as latest Hydra doesn't compile with
`pkgs.nixStable` and to ensure a graceful migration using the newly
introduced packages.

To verify the approach, a simple vm-test has been added which verifies
the migration steps.

nixos/hydra: incorporate upstream changes and update test
During the last update, `hydra-notify` was rewritten as a daemon which
listens to postgresql notifications for each build[1]. The module
uses the `hydra-notify.service` unit from upstream's Hydra module and
the VM test ensures that email notifications are sent properly.

Also updated `hydra-init.service` to install `pg_trgm` on a local
database if needed[2].

nixos/hydra: fix test
We ship `https://cache.nixos.org` as binary cache by default which
automatically substitutes the test derivation used inside the Hydra
test. However it needs to be built locally to confirm that
`hydra-queue-runner` works properly.

Also inherited the platform name for the test derivation from `system`
to ensure that the build can be tested on each supported platform.

nixos/hydra: enhance test for multiple Nix versions
Hydra should support multiple Nix versions (and currently contains fixes
to work with Nix 2.0 and higher).

Further Nix versions can be added to the `hydraPkgs` expression in the
test case which lists all supported Nix versions for Hydra.

hydra: 2017-11-21 -> 2018-08-07
This bumps Hydra to the latest revision available. As Hydra doesn't have
a release model (and therefore no tags) ATM, the derivation will pin
against the actual git revision and the date of the commit in the
derivation name.

Additionally the following changes have been made:

* Dropped `postUnpack` phase. It is useful when working with the Hydra
  source (and no dirty changes shall be used in `release.nix`, but is has
  no use in `nixpkgs`).

* Added myself as maintainer to have more folks available in case of
  future breakage.

* Implemented support for Nix 2.0 and `unstable` (currently 2.1):

  Since 1672bcd230447f1ce0c3291950bdd9a662cee974 in NixOS/nix the
  evaluator differentiates between `settings` and `evalSettings`.
  Previously `restrictEval` in `hydra-eval-jobs.cc` has been set in
  `settings`, this doesn't work anymore in Nix 2.1 and is therefore
  incompatible to Nix 2.0 on an API level.

  To resolve this, the flag `isGreaterNix20` parses the version string
  of `pkgs.nix` and applies a patch if nix.version<=2.0.

  Furthermore the Hydra build with Nix 2.1 requires `boost` as build input
  which is not needed for Nix 2.0. To avoid unnecessary increase in the
  closure size this library will only used as build input for
  nix.version>2.0.

* Fixed the NixOS test for `hydra`:
  disabled binary cache to allow sandbox builds (otherwise it would
  query `cache.nixos.org` during the Hydra build inside the test).

  Additionally the trivial.nix jobset required simplification (as done
  in NixOS/hydra, e.g. tests/api-test.nix) as bash is not available in
  the build sandbox as builder (even when adding pkgs.bash to
  systemPackages).

  The easiest workaround to confirm a the functionality of a jobset
  without importing nixpkgs is to use the default shell /bin/sh which
  is mounted from `pkgs.busybox` into the build env
  (https://github.com/NixOS/nixpkgs/pull/44841#discussion_r209751972) in the
  VM and a named pipe to create $out.

Closes #44044

Antoine Eiche 47fc27b456 nixos/tests/hydra: build a trivial derivation
A script is used to create a project, and configure a jobset. This
jobset fetches a local file containing a trivial Nix expression. The
test script makes sure this derivation has been successfully built by
Hydra.
