configuration-nix.nix uses builtins.intersectAttrs to not any overrides
for packages not present in `super` (presumably for use outside of
nixpkgs?). To accomodate it, we pass an attribute set with every
attribute of haskellPackages, but set to `null` as `super`, and — while
we're at it — a fix point as `self`.
While being able to test them is neat (on x86_64-linux they work very
well, actually), we usually don't want to do this, since the set is
only (recommended to be) used to bootstrap GHC. Consequently there is
almost no binary cache and testing them mostly leads to unenlightening
and seemingly endless compilation.
The added nix expression allows maintainers to check for regressions in
the configuration overlays employed by haskellPackages and friends. The
reasoning behind this is that, if we add an override for something, it
should also build. To test this fact, we extract all attributes touched
by a configuration and obtain all relevant derivations corresponding to
it which can then be thrown into nix-build --keep-going.
I've been using this expression to verify configuration-ghc-9.2.x.nix
for a week or so which works quite well. The amount of stale overrides
in other configuration makes it a bit more painful for other use cases
at the moment.
The "0.5.0-1" rockspec on luarocks has a bug, resulting in it pulling
the current git master version, which is what we have effectively been
using.
Given that 0.5.0-1 is the latest release, is 6 years old, and that there
have been some bug fixes since then, we do actually want to be using the
git master version, but we also want to be using the correct rockspec
(particularly as alt-getopt has been replaced by argparse in the `moon`
binary).
Avoiding passthru itself was the right direction, but not a
complete solution. Passthru attributes typically do not contain
dependencies, but rather extra paths that are not relevant to
the build itself.
Whether we want to include all (passthru) test dependencies this
way can be debated, but removing them makes this expression more
robust.
When updating a package using nix-update-script with `--argstr commit true`,
update.nix would not detect the changes because nix-update would stage them
and `git diff` would be empty.
We now detect both staged and unstaged changes to handle this use case.
- luarocks-nix: bumped to pass args too, `package_X = callPackage ...`.
It allows to remove the annoying `with self`.
This new version disables tests (because broken) and now emits derivation
with a callPackage in front.
- replaced X.override with lib.overrideLuarocks, it should be used
whenever buildInputs/extraVariables is changed since it impacts the
generated luarocks config.
Once structured attributes are in, it will be easier to have the
luarocks config generated by a hook and we probably will be able to
replace all overrideLuarocks by overrideAttrs.
* maintainers/scripts/rebuild-amount.sh: report parallelism setting
This slightly helps discovering parallelism support.
* maintainers/scripts/rebuild-amount.sh: add basic example
It's not clear if script should be used against HEAD or HEAD^.
Let's have a copyable example.
* maintainers/scripts/rebuild-amount.sh: convert tabs to four spaces
One notable change is here-document conversion.
Before:
<TAB>cat <<-FOO
<TAB>...
<TAB>FOO
After:
<sp><sp><sp><sp>cat <<FOO
<sp><sp><sp><sp>...
FOO
Note seemingly misaligned 'FOO': '-FOO' understands leading tabs,
but not spaces.
I noticed this minor grammar mistake when running update.nix, and then
while grepping to find the source I noticed we had it a few times in
Nixpkgs. Just as easy to fix treewide as it was to fix the one
occurrence I noticed.
Upstream is working on some major deprecations, being on a HEAD commit
will not be a good plan going forward.
Remove double `busted` in `checkInputs` - keep only 1.
If the script is executed in a CI (like in github actions, with the
install-nix-action) it fails. This changes fixes that use case. In that
scenario, you should provide the --no-commit flag.
Since Bundler 2+, the lock command generated platform-dependent
Gemfile.locks, which breaks when nix has to build gems from source,
because the gemset generated is tied to the platform which generated it.
Trying to reuse the update scripts used by kakoune/vim to provide the
user with an unified convergence. Some stuff doesn't work yet (parallel
download, caching) but I (anyone else welcome to try too) will improve
it in other PRs.
This commit shows how to convert luarocks packages into (neo)vim ones.
The advantage for neovim lua plugins to register their rockspec (aka
package definition) is that the plugin can express its dependencies and
a few metadata through it.
This should fix

Allow setting the HACKAGE2NIX environment variable to change the
hackage2nix the script uses to an absolute path to a local build. Useful
to test local changes in a realistic environment.
The distinction between the inputs doesn't really make sense in the
mkShell context. Technically speaking, we should be using the
nativeBuildInputs most of the time.
So in order to make this function more beginner-friendly, add "packages"
as an attribute, that maps to nativeBuildInputs.
This commit also updates all the uses in nixpkgs.
We split configuration-hackage2nix.yaml into multiple files. We bump
cabal2nix-unstable to get support for multiple config files in
hackage2nix.
* The file main.yaml is only supposed to be edited by humans.
* The file stackage.yaml is only supposed to be updated by the
update-stackage.sh
* The file broken.yaml can be edited by humans, but probably future
helpers will want to insert broken packages into this file based on
hydra reports.
* The file transitive-broken.yaml is newly introduced to be generated
by regenerate-transitive-broken-packages.sh
regenerate-transitive-broken-packages.sh makes a nix query (in
transitive-broken-packages.nix) which evaluates all haskellPackages
once with and once without "allowBroken" this way it get's a list of
packages which are broken by some transitive dependency, but does not
disable packages which have eval errors not caused by a broken package.
When an update script fails, it might still modify the source tree.
These changes would then be committed in the next update attempt.
Let’s make sure the worktree is clean before updating to avoid that.
This is the preferred format for things fetched from git or similar that
are not proper releases: https://nixos.org/manual/nixpkgs/stable/#sec-package-naming
Also we should think about making name and attribute name more
consistent: cabal2nix-latest -> cabal2nix-unstable
Introduces a script that can be used to update the Nix expressions for
the Haskell package set. In service of that, also
- introduces cabal2nix-latest, which pins the hackage2nix version used
- changes all-cabal-hashes to use fetchFromGitHub
- adds update-hackage.sh & update-cabal2nix-latest.sh & update-stackage.sh maintainer scripts
