when you register a runner with spaces in its name (possible if you use 'description' option) then the runners never get unregistered because our bash scripts assume no space in names.
This solves the issue
Retreiving the fullname of the runner via `gitlab-runner list` got surprisingly hard between lazy-capture issues and `gitlab-runner list` displaying invisible (CSI) characters that break the regex etc.
Which is why I fell back on the pseudo-json format.
This PR adds the hash in the name, which allows to keep both the
stateless aspect of the module while allowing for a freeform name.
I found using bash associative arrays easier to use/debug than the current
approach.
conversions were done using https://github.com/pennae/nix-doc-munge
using (probably) rev f34e145 running
nix-doc-munge nixos/**/*.nix
nix-doc-munge --import nixos/**/*.nix
the tool ensures that only changes that could affect the generated
manual *but don't* are committed, other changes require manual review
and are discarded.
The description for the runner in the UI is by default sthg like
"npm_nixos_d0544ed48909" i.e., the name of the attribute.
I wanted to have a more user-friendly description and added a
description to the service.
Seems like gitlab-runner doesn't like having both fields set:
"Cannot use two forms of the same flag: description name"
so I used one or the other.
The `nix.*` options, apart from options for setting up the
daemon itself, currently provide a lot of setting mappings
for the Nix daemon configuration. The scope of the mapping yields
convience, but the line where an option is considered essential
is blurry. For instance, the `extra-sandbox-paths` mapping is
provided without its primary consumer, and the corresponding
`sandbox-paths` option is also not mapped.
The current system increases the maintenance burden as maintainers have to
closely follow upstream changes. In this case, there are two state versions
of Nix which have to be maintained collectively, with different options
avaliable.
This commit aims to following the standard outlined in RFC 42[1] to
implement a structural setting pattern. The Nix configuration is encoded
at its core as key-value pairs which maps nicely to attribute sets, making
it feasible to express in the Nix language itself. Some existing options are
kept such as `buildMachines` and `registry` which present a simplified interface
to managing the respective settings. The interface is exposed as `nix.settings`.
Legacy configurations are mapped to their corresponding options under `nix.settings`
for backwards compatibility.
Various options settings in other nixos modules and relevant tests have been
updated to use structural setting for consistency.
The generation and validation of the configration file has been modified to
use `writeTextFile` instead of `runCommand` for clarity. Note that validation
is now mandatory as strict checking of options has been pushed down to the
derivation level due to freeformType consuming unmatched options. Furthermore,
validation can not occur when cross-compiling due to current limitations.
A new option `publicHostKey` was added to the `buildMachines`
submodule corresponding to the base64 encoded public host key settings
exposed in the builder syntax. The build machine generation was subsequently
rewritten to use `concatStringsSep` for better performance by grouping
concatenations.

Also removes configText, functionality is now provided more conveniently by configOptions.
Keep in mind that this breaks compatibility with previous configurations,
configFile provides a means to protect the CI token from being written into the nix store.
The current behavior was for gitlab-runner is to immediately terminate when there
was a restart required. This can lead to aborted builds and is annoying to users.
By enabling graceful mode gitlab-runner will wait for all builds to finish before
terminating. The disadvantage is that a nixos-rebuild switch needs to wait till
all jobs are done. Because of that it is not enabled by default.
