cabal2nix evaluation failures
Here's the reproduction:

I believe this is not the same thing as #9 since that is a build failure whereas this is an evaluation failure.
Hey Gabriel, thanks for the report.
The problem is in this line: https://github.com/nh2/static-haskell-nix/blob/d24dea3d46a727e1cd93e67458ce2768109efe0a/survey/default.nix#L460
The issue here seems to be that, probably via cabal2nix -> fetchurl -> curl -> zlib, somewhere zlib.static is used, and that is not overridable:
$ nix-shell -p 'pkgs.zlib.override {}'
# works fine
$ nix-shell -p 'pkgs.zlib.static.override {}'
error: attribute 'override' missing, at (string):1:94
Now I just need to find out what to do about it...
It's going to be this:
https://github.com/nh2/nixpkgs/blob/11aa987ea5b5a593c9ca7a38b391804959f905e5/pkgs/top-level/static.nix#L86-L93
{
zlib = (super.zlib.override {
static = true;
shared = false;
# Don’t use new stdenv zlib because
# it doesn’t like the --disable-shared flag
stdenv = super.stdenv;
}).static;
}
This was already accidentally fixed in nixpkgs master with https://github.com/NixOS/nixpkgs/pull/74485/files#diff-d125f8cf97a8da782a42f2f648415cd9L92 which removes the use of .static in favour of splitStaticOutput = false; inside the .override.
FYI @malbarbo @dtzWill @matthewbauer Check out the above and the previous two comments, it appears that we must never use .static outputs in things like static.nix because they are not overridable.
When I cherry-pick that, or use nixpkgs master, the next challenge I face is this infinite recursion:

infinite recursion encountered, at undefined position
I think I found the problem: the revision of nixpkgs that static-haskell-nix is currently using is responsible for the infinite recursion. When I update the nixpkgs revision to the latest master the evaluation errors disappear and the only error I have left is the same one as in https://github.com/nh2/static-haskell-nix/issues/29
Here is the change to the reproducing code that now instantiates successfully:

@Gabriel439 Ah that's great.
Do you happen to know which nixpkgs commit is the fix?
I currently cannot (trivially / have not tried yet) upgrade to latest nixpkgs master because my nightly CI shows that the latest master has important Haskell packages like darcs marked as broken:
https://buildkite.com/nh2/static-haskell-nix/builds/341#438409a8-05e1-48a6-8000-b30d5511679f
error: Package ‘darcs-2.14.2’ in /nix/store/lc4aal3h7iqz0cbr6dfpjnrbnig76whk-source/pkgs/development/haskell-modules/hackage-packages.nix:64807 is marked as broken, refusing to evaluate.
My plan so far was to wait until nixpkgs has figured that out, but if it happens to be darcs-specific (as evaluations show only the first error), we could also just disable that for now.
@Gabriel439 No I mean whether you happen to know which specific commit got rid of the infinite recursion (then I could consider picking it to not break darcs and whatever other Haskell stuff may be broken in current nixpkgs master).
~Actually, I think I know which commit is inolved here (fromt the Github backlink further up):~
~https://github.com/NixOS/nixpkgs/pull/74485#pullrequestreview-351188110~
Sorry, that was for the missing attribute, not the infinite recursion.
Looking into this, I hit https://github.com/NixOS/nixpkgs/pull/83825, but you already took care of that.
Here is the change to the reproducing code that now instantiates successfully:
@Gabriel439 That doesn't work for me:

@nh2: Yeah, I didn't get that far yet (I got stuck on the coreutils build failure). I just meant that it fixes the evaluation failure
@nh2: Also, for that specific error you can probably fix it by s/1.29/1.29.0/
for that specific error you can probably fix it by
s/1.29/1.29.0/
Thanks, that's what I needed indeed.
I mean whether you happen to know which specific commit got rid of the infinite recursion
I bisected it; it is commit https://github.com/NixOS/nixpkgs/commit/2645e1a1eb41742905394db9d7679a1bb3343eeb by @madjar that fixed it, merged as part of https://github.com/NixOS/nixpkgs/pull/82345.
Cherry-picking it on top of my current static-haskell-nix-2020-02-05 nixpkgs branch (commit https://github.com/nh2/nixpkgs/commit/0c960262d159d3a884dadc3d4e4b131557dad116) makes the infinite recursion go away there.
I got stuck on the
coreutilsbuild failure
@Gabriel439 What's your plan for that? I'm pretty sure that these days you can use the nix sandbox and nix-daemon also on non-NixOS.
I now got stuck at a bad archive: input doesn't look like a Nix archive error when trying to copy down base-compat:
copying path '/nix/store/a1bsf33rrc7daxna17hbk1y4a61a9qxx-base-compat-0.10.5' from 'https://static-haskell-nix.cachix.org'...
bad archive: input doesn't look like a Nix archive
This was reproducible every time.
This worked around it:
% nix-copy-closure --from static-haskell-nix-ci /nix/store/a1bsf33rrc7daxna17hbk1y4a61a9qxx-base-compat-0.10.5
copying 1 paths...
copying path '/nix/store/a1bsf33rrc7daxna17hbk1y4a61a9qxx-base-compat-0.10.5' from 'ssh://static-haskell-nix-ci'...
Very suspicious.
Edit: Probably this: https://github.com/cachix/cachix/issues/251#issuecomment-606930271
The next error I encounter is due to krb5 recently breaking (and even more recently re-fixing) musl support: https://github.com/krb5/krb5/commit/b009cca2026b615ef5386faa4c0230bc27c4161d

Perhaps the fix of https://github.com/NixOS/nixpkgs/commit/2645e1a1eb41742905394db9d7679a1bb3343eeb just made us lucky by removing something similar to fetchpatch and using download (curl?) related things is in fact still broken?

@nh2: Also, is there any reason why Hydra's CI does not check that these things build correctly? It seems like it would make your life easier if people couldn't introduce nixpkgs changes that break musl builds
@nh2 Here's the PR where the boot compiler was updated: https://github.com/NixOS/nixpkgs/pull/83048
As far as I know, no one is testing that GHC builds with musl when merging in things like this.
For testing things like this, is there some attribute I can give to ofborg to test stuff like this?
For example, on https://github.com/NixOS/nixpkgs/pull/83048, should I have run something like @grahamcofborg build pkgsMusl.haskell.compilers.ghc865binary?
@nh2 I've deleted the offending store path, make sure to use Cachix 0.3.7 as it avoids this rare but quite annoying problem :)
Also, is there any reason why Hydra's CI does not check that these things build correctly? It seems like it would make your life easier if people couldn't introduce nixpkgs changes that break musl builds
@Gabriel439 Absolutely, it would make it a lot easier. I guess it would double the amount of building that Hydra would have to do. I imagine in the future we can gather enough musl supporters or infrastructure to make it happen nevertheless.
As far as I know, no one is testing that GHC builds with musl when merging in things like this.
@cdepillabout That's probably right!
For example, on NixOS/nixpkgs#83048, should I have run something like
@grahamcofborg build pkgsMusl.haskell.compilers.ghc865binary?
I think that would work, yes. The only problem with ofborg is that it limits builds to 3600 seconds or so. So some larger builds may not complete.
What I'd really want would be to hook my community-sponsored builder into the PR/ofborg infrastructure and have it automatically build the relevant musl musl things. But ofborg currently does not support that.
I've deleted the offending store path, make sure to use Cachix 0.3.7 as it avoids this rare but quite annoying problem :)

It's about to jump to 0x402010, which is inside the rw- memory range (not the r-x range) for conftest-2.

And stepping once more segmentation faults.
After chasing issues down, it looks like NixOS/nixpkgs#84741 fixed this problem, and applying NixOS/nixpkgs@acfccf7f5ba83ce4ec279ce4416e5de5edca2fb7 to nixos-20.03 lets GHC build properly.
Cloning Aura & running nix-build ./nix -A staticProject.static_package will give you a successful static build using nixos-20.03, Stack 2.1, and Stackage lts-15.13. Not sure how to go about upstreaming all the patches in there to make those play. (At least the Nixpkgs patch shouldn't be necessary on nixos-unstable (as the merged commit, https://github.com/NixOS/nixpkgs/commit/4675649d9cd06d13f8f127855dda4993881dd81b, is present.)
