various: switch buildPythonApplication packages to use finalAttrs

[quantenzitrone]

this shouldn't create any rebuilds

the following script was used to generate this:

#!/usr/bin/env fish

# nix shell .#nixfmt nixpkgs#{nixf-diagnose,ripgrep,sd}

set base (git rev-parse HEAD)

set scope pkgs/by-name
set builder buildPythonApplication

set files (rg --files-with-matches -F "$builder rec {" $scope | sort -u)

for file in $files
    echo $file
    sd -F "$builder rec {" "$builder (finalAttrs: {" $file

set torestore (rg -F finalAttrs.pname --files-with-matches $scope)

    git restore $torestore
end

# commit for faster eval times
git add pkgs
git commit --no-gpg-sign -m temp
set torestore

for file in $files
    # file hasn't changed
    if git diff --quiet $base $file
        continue
    end
    # try to eval the package to definitely catch all errors
    echo $file
    set pname (string split / $file -f 4)
    if ! nix eval .#$pname
        set torestore $torestore $file
    end
end

# restore files that don't eval
git reset --soft $base
git restore --staged .
if test (count $torestore) -gt 0
    git restore $torestore
end

after that some manual cleanup was done:

• restoring files that cause changes in the number of lines
• restoring files that cause rebuilds
• restoring files that cause merge conflicts with staging

Things done

• checked that all uses of pname from finalAttrs are legit
  • all but 1 are used as arguments to fetchPypi or fetchCargoVendor
• no rebuilds
• merges cleanly with staging (checked on 2026-02-07T10:00 merging into b0d1142)
  • to not annoy k900 with merge conflicts
• changes do not require release notes
• Fits CONTRIBUTING.md, pkgs/README.md, maintainers/README.md and other READMEs.

Needs a rebase due to merge conflicts, otherwise LGTM.

netbox.pythonPath fails to evaluate, probably a few other attrs that aren't part of the derivation's eval as well.

error: attribute 'dependencies' missing
       at <nixpkgs>/pkgs/by-name/ne/netbox_4_4/package.nix:111:41:
          110|     # PYTHONPATH of all dependencies used by the package
          111|     pythonPath = py.pkgs.makePythonPath finalAttrs.dependencies;
             |                                         ^
          112|     inherit (py.pkgs) gunicorn;

A similar thing happened in #480960, so perhaps this should be held off until these issues with the Python finalAttrs builder are resolved.

[SigmaSquadron]

Ditto with nipap-www.

Those seem to be the only two instances of finalAttrs.dependencies.

It's fixable by replacing dependencies with propagatedBuildInputs, as there's a few other pythonPaths that use propagatedBuildInputs and it evals fine.

[SigmaSquadron]

Evaluated all packages, mapping for passthru.tests. Aside from the two above, everything seems good.

[quantenzitrone]

i restored the affected packages
no package is using finalAttrs.dependencies

$ rg 'finalAttrs.*dependencies' (git show HEAD | rg -F '+++ b/' | cut -d / -f 2-)
< no matches >

[SigmaSquadron]

With those removed, I believe it should be okay to merge.
