This has been not touched in 6 years. Let's remove it to cause less
problems when adding new cross-compiling infrastructure.
This also simplify gcc significantly.
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
* The ELK stack is upgraded to 6.3.2.
* `elasticsearch6`, `logstash6` and `kibana6` now come with X-Pack which is
a suite of additional features. These are however licensed under the unfree
"Elastic License".
* Fortunately they also provide OSS versions which are now packaged
under: `elasticsearch6-oss`, `logstash6-oss` and `kibana6-oss`.
Note that the naming of the attributes is consistent with upstream.
* The test `nix-build nixos/tests/elk.nix -A ELK-6` will test the OSS
version by default. You can also run the test on the unfree ELK using:
`NIXPKGS_ALLOW_UNFREE=1 nix-build nixos/tests/elk.nix -A ELK-6 --arg enableUnfree true`
