When the `keep-going` option is set to `true`, make `nix flake check`
continue as much as it can before failing.
The UI isn’t perfect as-it-is as all the lines currently start with a
mostly useless `error (ignored): error:` prefix, but I’m not sure what
the best output would be, so I’ll leave it as-it-is for the time being
(This is a bit hijacking the `keep-going` flag as it’s supposed to be a
build-time only thing. But I think it’s faire to reuse it here).
Fix https://github.com/NixOS/nix/issues/4450
When adding a path to the local store (via `LocalStore::addToStore`),
ensure that the `ca` field of the provided `ValidPathInfo` does indeed
correspond to the content of the path.
Otherwise any untrusted user (or any binary cache) can add arbitrary
content-addressed paths to the store (as content-addressed paths don’t
need a signature).
Linux is (as far as I know) the only mainstream operating system that
requires linking with libdl for dlopen. On BSD, libdl doesn't exist,
so on non-FreeBSD BSDs linking will currently fail. On macOS, it's
apparently just a symlink to libSystem (macOS libc), presumably
present for compatibility with things that assume Linux.
So the right thing to do here is to only add -ldl on Linux, not to add
it for everything that isn't FreeBSD.
Only considers the closure in term of `Realisation`, ignores all the
opaque inputs.
Dunno whether that’s the nicest solution, need to think it through a bit
Align all the worker protocol with `buildDerivation` which inlines the
realisations as one opaque json blob.
That way we don’t have to bother changing the remote store protocol
when the definition of `Realisation` changes, as long as we keep the
json backwards-compatible

Move the `closure` logic of `computeFSClosure` to its own (templated) function.
This doesn’t bring much by itself (except for the ability to properly
test the “closure” functionality independently from the rest), but it
allows reusing it (in particular for the realisations which will require
a very similar closure computation)
When you have a symlink like:
/tmp -> ./private/tmp
you need to resolve ./private/tmp relative to /tmp’s dir: ‘/’. Unlike
any other path output by dirOf, / ends with a slash. We don’t want
trailing slashes here since we will append another slash in the next
comoponent, so clear s like we would if it was a symlink to an absoute
path.
This should fix at least part of the issue in
https://github.com/NixOS/nix/issues/4822, will need confirmation that
it actually fixes the problem to close though.
Introduced in f3f228700a.
Accidentally removed in ca96f52194. This
caused `nix run` to systematically fail with
```
error: app program '/nix/store/…' is not in the Nix store
```
