XXX: This is essentially the same as:
|
|
|
|
builtins.tryEval (builtins.fetchurl url)
|
|
|
|
... except that tryEval on fetchurl isn't working and doesn't catch
|
|
errors for fetchurl, so we go for a different approach.
|
|
|
|
We only have fixed-output derivations that can have networking access, so
|
|
we abuse SHA1 and its weaknesses to forge a fixed-output derivation which
|
|
is not so fixed, because it emits different contents that have the same
|
|
SHA1 hash.
|
|
|
|
Using this method, we can distinguish whether the URL is available or
|
|
whether it's not based on the actual content.
|
|
|
|
So let's use tryEval as soon as it's working with fetchurl in Nix.
