hie from all-hies is not using overrided cabal packages

Hi,
I have a project in which I have an overlay for overriding some Haskell packages along with the overlay provided by this library (thanks btw). If I start a nix shell, I can then run cabal build for example, inside the shell and my project is built correctly using the overriden packages, etc. However, when I fire off hie , it fails apparently cause it still tries to use the packages available from the hackage package list installed under ~/.cabal, not the packages provided by my nix derivation. Here:
My default.nix:
{dev ? true}:
let
base = import <nixpkgs> {};
pinnedVersion = base.pkgs.lib.importJSON ./nixpkgs.json;
nixpkgs = base.pkgs.fetchFromGitHub {
owner = "NixOS";
repo = "nixpkgs";
inherit (pinnedVersion) rev sha256;
};
all-hies = fetchTarball {
url = "https://github.com/infinisil/all-hies/tarball/eff5d9a5e1a84150014095494331cf63e59923af";
sha256 = "19bws9fyjhgiikig86cri05fxz1wrz60n69zrigq5wzbyn4hwv9h";
};
persistent-repo = builtins.fetchGit {
url = "https://github.com/drchaos/persistent.git";
rev = "434014afdfb0000e3d839ea4c6c120c9720db740";
ref = "latest_persistent";
};
persistent-mysql-haskell-path =
builtins.concatStringsSep "/" [persistent-repo.outPath "persistent-mysql-haskell" ];
overlay = self: super: {
localHaskellPackages =
super.haskell.packages.ghc883.override (old: {
overrides = self.lib.composeExtensions (old.overrides or (_: _: {}))
(hself: hsuper: {
mkDerivation = args : hsuper.mkDerivation (args // {
doCheck = false;
doHaddock = false;
enableLibraryProfiling = false;
});
ghc = hsuper.ghc // {withPackages = hsuper.ghc.withHoogle;};
ghcWithPackages = hself.ghc.withPackages;
persistent-mysql-haskell = hself.callCabal2nix "persistent-mysql-haskell" persistent-mysql-haskell-path {};
mysql-haskell = hself.callCabal2nix "mysql-haskell" (
builtins.fetchGit {
url = "https://github.com/drchaos/mysql-haskell.git";
rev = "4de0a7e2640d8d68f381a1471a24e906e3f09124";
ref = "base_413";
}) {};
});
});
};
devToolsOverlay = if dev then [(import all-hies {}).overlay] else [];
pkgs = import nixpkgs {
overlays = [overlay] ++ devToolsOverlay;
};
drv = pkgs.localHaskellPackages.callCabal2nix "sase" (
builtins.filterSource
(path: type: type != "directory" || baseNameOf path != ".git") ./.
) {};
in
drv.env.overrideAttrs (
old: with pkgs.localHaskellPackages; {
shellHooks = "hpack";
nativeBuildInputs =
let devTools = if dev then [hie] else [];
tools = [ cabal-install ];
in old.nativeBuildInputs ++ tools ++ devTools;
}
)
then I run a nix-shell and do cabal build and things build fine.. (not posting here for brevity's sake). Now I fire off my editor (Sublime Text) and I see the following in the LSP debug output:

These packages are currently broken, that's why I had to override them in my default.nix .. and I know that works cause I can build with cabal inside a nix shell normally etc...
Now.. here is the really weird part.. if I grab the command above and just run it by hand, i.e. cabal v2-build --with-ghc... , it actually succeeds in the nix shell !!.. the overriden nix packages are used and the conflicts are resolved.
I even nuked the ~/.cache and ~/.cabal directories.. again.. things work of course ok inside the nix-shell building manually.. but if I run hie...
cabal-helper: Installing a private copy of Cabal because we couldn't
find the right version anywhere on your system. You can set the environment
variable CABAL_HELPER_DEBUG=1 to see where we searched.
Note that this installation might take a little while but it will only
happen once per Cabal library version used in your build-plans.
If you want to avoid this automatic installation altogether install
version 3.2.0.0 of the Cabal library manually, either using cabal or your
system package manager. With cabal you can use the following command:
$ cabal install Cabal --constraint "Cabal == 3.2.0.0"
FYI the build products and cabal-helper executable cache are all in the
following directory, you can simply delete it if you think something
is broken :
/Users/erick/.cache/cabal-helper
but then again:
$ which cabal
/nix/store/pv127qh7r7nzcv9j4ci024ziaabrsps3-cabal-install-3.2.0.0/bin/cabal
$ cabal --version
cabal-install version 3.2.0.0
compiled using version 3.2.0.0 of the Cabal library
I am hesitant to raise the issue first with the haskell-ide-engine project cause I am afraid they are going to say.. well.. it is nix problem... which it might be I guess.. at least I think it is fair to look at this side of things first and figure out who is misbehaving or if I am doing the overrides wrong or if it is all-hies that is doing the override incorrectly.. not sure.. your help is appreciated 🙏
Thanks!

Can you show the full logs after nuking ~/.cache/cabal-helper and then running hie? Doesn't matter if it's a bit longer. Tip: You can format the comment like this to have an expandable section:
<details>
```
lots of logs here
```
</details>

Thanks for the tip ..good to know. See below. In fact this is after removing ~/.cabal (I was desperate last night.. still am :-)

hie: panic! cabal-helper: Installing Cabal version 3.2.0.0 failed.
You have the following choices to fix this:
- The easiest way to try and fix this is just reconfigure the project and try
again:
$ cabal clean && cabal configure
- If that fails you can try to install the version of Cabal mentioned above
into your global/user package-db somehow, though you'll probably have to
fix something otherwise it wouldn't have failed above:
$ cabal install Cabal --constraint 'Cabal == 3.2.0.0'
- If you're using `Build-Type: Simple`:
- You can see if you can reinstall your cabal-install executable while
having it linked to a version of Cabal that's available in you
package-dbs or can be built automatically:
$ ghc-pkg list | grep Cabal # find an available Cabal version
Cabal-W.X.Y.Z
$ cabal install cabal-install --constraint 'Cabal == W.X.*'
Afterwards you'll have to reconfigure your project:
$ cabal clean && cabal configure
- If you're using `Build-Type: Custom`:
- Have cabal-install rebuild your Setup.hs executable with a version of the
Cabal library that you have available in your global/user package-db:
$ cabal clean && cabal configure
You might also have to install some version of the Cabal to do this:
$ cabal install Cabal
Now, for the sake of digging further, I did cabal update to fetch the hackage package db which I had nuked before in desperation .. then I repeat the hie invocation. Now it succeeds in installing its own copy of cabal (why doesn't it like the one I am providing with nix? 🤔 ..hmm.. it is also cabal-3.2.0.0 .. ).. for completion's sake, these are the logs of that:

I'm pretty sure that cabal-helper requires whatever Cabal (the library) version that cabal --numeric-version (the cabal binary from cabal-install) gives back, which is probably 3.2.0.0 in your case. However you probably only have Cabal 3.0.1.0 in the environment (you can see that with ghc-pkg list).
There might be a better way to fix this, but check out how I did it in the nixpkgs-infra template, specifically https://github.com/Infinisil/all-hies/blob/eff5d9a5e1a84150014095494331cf63e59923af/templates/nixpkgs-infra/all-hies-template.cabal#L18-L20 and https://github.com/Infinisil/all-hies/blob/eff5d9a5e1a84150014095494331cf63e59923af/templates/nixpkgs-infra/default.nix#L29-L35
In your case this would be Cabal_3_2_0_0 (your nixpkgs version should have that). If you then check ghc-pkg list it should contain that version of Cabal, and you should be able to remove ~/.cache/cabal-helper and run hie to have it use the version provided by Nix.

Hmm.. I see.. ok I understand the problem in principle.. however.. I am a bit puzzled.. where is that Cabal_3_0_1_0 coming from? .. (and that is more of a question for myself but still hoping you might just have an inkling where that might be indeed coming from) .. I mean my base version of nixpkgs is fairly recent and it does offer Cabal_3_2_0_0 along with Cabal_2_4_1_0 and Cabal_2_2_0_1. .. there is no 3_0_1_0 in my Nixpkgs .. and I myself aren't overriding that anywhere in my infrastructure.. so I must conclude some package I am using is overriding that in? .. my goodness how can one track that?
I just tried adding an explicit override in my default.nix to use Cabal 3.2.0.0 and it still shows 3.0.1.0 in my ghc-pkg list..
Hmm.... 🤔
like:
nix-repl> base = import <nixpkgs> {}
nix-repl> pinnedVersion = base.pkgs.lib.importJSON ./nixpkgs.json
nix-repl> nixpkgs = import (base.pkgs.fetchFromGitHub {owner = "NixOS";repo = "nixpkgs"nix-repl> nixpkgs = import (base.pkgs.fetchFromGitHub {owner = "NixOS";repo = "nixpkgs";inherit (pinnedVersion) rev sha256;}) {}

Cabal 3.0.1.0 comes shipped with the GHC version, https://www.snoyman.com/base has an overview of which GHC ships which Cabal versions.
As long as ghc-pkg list has Cabal-3.2.0.0 it should work. E.g. the nixpkgs-infra template has this output for ghc-pkg list:
/nix/store/zvxw1wz5lqz7cl292q74pkv7nn0fsn0m-ghc-8.6.5-with-packages/lib/ghc-8.6.5/package.conf.d

Both the change in the cabal file and the default.nix I showed in #65 (comment) are needed for this (but use Cabal_3_2_0_0 in your case)

Ok got it .. thanks. I am closing this since it really isn't an issue with all-hies. Cheers and thanks for your help!
