[Nix-dev] how to debug the binary cache

[Gergely Risko]

Hi,

Here is a build: http://hydra.nixos.org/build/6046495

And here is the corresponding narinfo:
HEAD http://cache.nixos.org/rij57njvzwsbc2iwdscgnk47l8zrm62n.narinfo

But actually the .narinfo doesn't exist yet and I'd like to know why and
how long do I have to wait before the binary cache gets updated after a
hydra build.  Do every build go to the binary cache?  How is that
decided?  Is there a dashboard somewhere to check?  How about old stuff,
what is the garbage collection policy on the binary cache?

Any pointers?

Thanks in advance,
Gergely
