Upgrade nixpkgs

[robx]

Attempt to upgrade nixpkgs. I initially tried this in #2349, where it caused trouble with the static build, prompting me to file #2478, so chances are there'll be problems with the static build here.

The problem was:

error: infinite recursion encountered

       at /nix/store/46v5hkwaa7aadrdn3gadlcx8ckrv3brj-source/pkgs/stdenv/generic/make-derivation.nix:311:7:

which somehow involved the lens override which used callHackageDirect to fetch lens-5.1. Now changed to use nixpkgs-provided lens-5.2 (although it's entirely unclear what was the problem -- we use callHackageDirect just fine for e.g. hasql-pool.

A wild stab at a fix for the hackage2nix -lcrypto error: In nixpkgs commit 2a49c87bc5365ebbaad4cc3eebdec78b2474cf6e, hopenssl was changed to depend on openssl_1_1 instead of openssl. So b8a3be8 patches static-haskell-nix to apply the same static linking override to openssl_1_1 as to openssl. I'm a bit unsure whether the openssl_1_1 change is even new with respect to this nixpkgs bump though. Let's see how the static build goes...

Q: Which dependency requires lcrypto, libpq?

If this has something to do with postgis, I was thinking we could remove it from the nix packages.

[robx]

I think my latest changes might have fixed the build, but it seems it's being timed out after 360 minutes...

Not sure what to do about this. Could we try to somehow seed cachix with some partial dependencies, e.g. just the ghc and base packages?

It's via cabal2nix (or its component hackage2nix).

[steve-chavez]

Yeah, it says 6 hours here: https://docs.github.com/en/actions/learn-github-actions/usage-limits-billing-and-administration#usage-limits.

Yes, could you remind me which command I need to run for this? I'll create a temporary cachix token(I've also followed up on this on email).

There is a postgrest-push-cachix command. Is that what you're looking for?

[wolfgangwalther]

just rebased. I pushed cachix before, so that CI doesn't time out.
