I’ve been playing/learning/running hydra… this isn’t a question , more an observation… (this is no fault with hydra, more on how parts the internet ‘vanish’!)
Pretty impressive stuff… …there’s a distinct lack of documentations, but hey… that’s what source code is for isn’t it ;-).
I tried to by a 20.03 nixos tree… and it works but many jobs fail with.
trying https://github.com/01org/libva/archive/2.5.0.tar.gz
curl: (22) The requested URL returned error: 404 Not Found
error: cannot download source from any mirror
builder for '/nix/store/r91slpp46v9fvxqw3vr10wy1lnrfv5d8-source.drv' failed with exit code 1
That’s perfectly correct, because the apart from 1 repo, everything else has been deleted. A classic case of the shifting sands of files and availability of code the internet. Thanks intel!!!
Enabling useSubstitutes = true; in hydra will fix this, as it will look for this file on a nixos.org cache.
but it goes to show you, what can be compiled today, might not be able to compiled tomorrow!.
interesting…
