Nixpkgs: Unstable channel hasn't updated for 2 weeks

[peti]

https://github.com/NixOS/nixpkgs-channels is stuck at fce7562cf46727fdaf801b232116bc9ce0512049 despite the fact that https://hydra.nixos.org/job/nixos/trunk-combined/tested#tabs-constituents shows multiple successful evaluations in the last couple of days. Does anyone know what is going on there?

[vcunat]

I don't, but there's a ticket already: https://github.com/NixOS/nixpkgs/issues/86922

A few days ago it seemed like (almost?) all channels were affected by this.

Only somewhat tangentially related but am I correct in that there are now somehow builds running during the evaluation of the jobset? - https://hydra.nixos.org/jobset/nixos/trunk-combined#tabs-errors

[vcunat]

OMG, that again... it sounds likely to be the reason why it's stuck. In the past I found it not easy to detect what's causing these.

@pbogdan Ouch, good catch. I'll change Hydra to disallow import-from-derivation. (We used to need that for RPM/Debian builds but we're no longer doing those.)

[edolstra]

IFD is now disabled. https://hydra.nixos.org/jobset/nixos/trunk-combined#tabs-errors shows the following offenders:

in job ‘nixos.tests.enlightenment.aarch64-linux’:
attempted to realize '/nix/store/59dahwsynp93wv4kgp29rrmqrz2hdhva-enlightenment-0.23.1.drv' during evaluation but 'allow-import-from-derivation' is false

in job ‘nixos.tests.os-prober.x86_64-linux’:
attempted to realize '/nix/store/qc9lx6bc1gnxv96d4kh6nqac4cn839yc-debian-9.8-stretch-i386.nix.drv' during evaluation but 'allow-import-from-derivation' is false

@vcunat Is this actually fixed? Presumably the IFD needs to be removed for the channel to advance.

[emilazy]

Ah, it seems those tests don't block the channel.

We can unpin the issue.
