Does not work with nix ca-derivations enabled

[Mic92]

As @regnat reportet it does not handle /realisations, which results in http 500er errors when using it as a cache on a daemon with ca-derivations enabled.

Is there some working alternative? I tried using nix-serve from this repo combined with NixOS/nix as a source for the underlying nix+perl-bindings, but perl does not like it: either it somehow does not find Nix/Config.pm, otherwise it appears to error out inside some Manifest.pm or such...

The workaround is not enabling ca-derivations until nix-serve implements ca-derivation support.

Is there some other nix cache which does support this? I suppose ngi0 uses S3, right?

[SuperSandro2000]

We explicitly need this type of cache and not S3 or some other cloud provider.

[Mic92]

Maybe nix.sshServe.enable works because it's part of nix?

yes, through hydra.

All the built-in store implementations support this. So ssh, ssh-ng, http(s), file, daemon and s3 stores should all be usable as a CA-aware binary cache
