* ocamlPackages.janeStreet_0_9_0: join the ocamlPackages fix point
Internal dependencies in the janeStreet sets were always taken from the
own rec attribute set. While this is pretty simple and convenient, it
has the disadvantage that it doesn't play nice with overriding: If you'd
override an attribute in a janeStreet set previously, it would be
changed when referenced directly, but the other packages in that
janeStreet set still would use the original, non-overridden version of
the derivation.
This is easily fixed by passing janeStreet_0_9_0 itself from the fix
point of ocamlPackages and using it to reference the dependencies.
Example showing it now works as expected:
test-overlay.nix:
self: super: {
ocamlPackages = super.ocamlPackages.overrideScope (old: _: {
janeStreet_0_9_0 = old.janeStreet_0_9_0 // {
base = old.janeStreet_0_9_0.base.overrideAttrs (_: {
meta.broken = true;
});
};
});
}
nix-repl> (import ./. {
overlays = [ (import ./test-overlay.nix) ];
}).ocamlPackages.janeStreet_0_9_0.stdio

a) To temporarily allow broken packages, you can use an environment variable
for a single invocation of the nix tools.
$ export NIXPKGS_ALLOW_BROKEN=1
b) For `nixos-rebuild` you can set
{ nixpkgs.config.allowBroken = true; }
in configuration.nix to override this.
c) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
{ allowBroken = true; }
to ~/.config/nixpkgs/config.nix.
* ocamlPackages.janeStreet: take part in fixpoint for OCaml >= 4.08
This change makes overrides to the janeStreet set work as expected by
making the janeStreet set take part in the ocamlPackages fixpoint for
janeStreet 0.14, i. e. OCaml >= 4.08
* ocamlPackages.janeStreet: take part in fixpoint for OCaml == 4.07
This change makes overrides to the janeStreet set work as expected by
making the janeStreet set take part in the ocamlPackages fixpoint for
janeStreet 0.12, i. e. OCaml == 4.07
* ocamlPackages.janeStreet: take part in fixpoint for OCaml < 4.07
This change makes overrides to the janeStreet set work as expected by
making the janeStreet set take part in the ocamlPackages fixpoint for
janeStreet 0.11, i. e. OCaml < 4.07
* ocamlPackages.janeStreet: remove self - super distinction
Previously, we inherited non-janestreet ocaml dependencies from super
and janestreet dependencies from self which always was super.janeStreet.
This behavior is however not really what we want due to liftJaneStreet:
Users and other packages will use ocamlPackages.base etc. instead of
ocamlPackages.janeStreet.base and the like. Consequently they also would
override the top-level attributes which would mean that other janestreet
packages would not pick up on it however.
As a consequence however, overriding ocamlPackages.janeStreet.base
doesn't work. Since this was never possible, I don't think this is an
issue. It is probably a good idea to deprecate that set anyways and
printing a warning when it is used via trace.
janeStreet_0_9_0 is unchanged as the disticniton between self and super
makes sense for it.
Below is an example showing how overriding would work from an user's
perspective:
test-overlay.nix:
self: super: {
ocamlPackages = super.ocamlPackages.overrideScope (old: _: {
base = old.base.overrideAttrs (_: {
meta.broken = true;
});
});
}
nix-repl> (import ./. { overlays = [ (import ./test-overlay.nix) ]; }).ocamlPackages.

Also note that not only a change to the option value will trigger a

* nixos/github-runner: remove mkDefault for DynamicUser=
* nixos/github-runner: create a parent for systemd dirs
Adds a parent directory "github-runner/" to all of the systemd lifecycle
directories StateDirectory=, RuntimeDirectory= and LogDirectory=.
Doing this has two motivations:
1. Something like this would required if we want to support multiple
runners configurations. Please note that this is already possible
using NixOS containers.
2. Having an additional parent directory makes it easier to remap
any of the directories. Without a parent, systemd is going to
complain if, for example, the given StateDirectory= is a symlink.
* nixos/github-runner: use specifier to get abs runtime path
* nixos/github-runner: use hostname as default for option `name`
Until now, the runner registration did not set the `--name` argument if
the configuration option was `null`, the default for the option.
According to GitHub's documentation, this instructs the registration
script to use the machine's hostname.
This commit causes the registration to always pass the `--name` argument
to the runner configuration script. The option now defaults to
`networking.hostName` which should be always set on NixOS.
This change becomes necessary as the systemd service name includes the
name of the runner since fcfa809 and, hence, expects it to be set. Thus,
an unset `name` option leads to an error.
* nixos/github-runner: use types.str for `name` option
Forcing a `name` option to comply with a pattern which could also be
used as a hostname is probably not required by GitHub.
* nixos/github-runner: pass dir paths explicitly for ExecStartPre=
* nixos/github-runner: update variable and script naming
* nixos/github-runner: let systemd choose the user/group
User and group naming restrictions are a complex topic [1] that I don't
even want to touch. Let systemd figure out the username and group and
reference it in our scripts through the USER environment variable.

* Revert "nixos/github-runner: use types.str for `name` option"
The escaping applied to the subdirectory paths given to StateDirectory=,
RuntimeDirectory= and LogsDirectory= apparently doesn't use the same
strategy that is used to escape unit names (cf. systemd-escape(1)). This
makes it unreasonably hard to construct reliable paths which work for
StateDirectory=/RuntimeDirectory=/LogsDirectory= and ExecStartPre=.
Against this background, I decided to (re-)apply restrictions to the
name a user might give for the GitHub runner. The pattern for
`networking.hostName` seems like a reasonable choice, also as its value
is the default if the `name` option isn't set.
This reverts commit 193ac67ba337990c22126da24a775c497dbc7e7d.
