Fixed composes issue for embroider + v1 addon

[wondersloth]

Summary

• This fix addresses the issue demonstrated here: css file hash doesn't use correct path when generating-scoped-name in embroider app build, when consuming an addon using ecm #278
• This is the minimal change to address the problem.
• In ModulesPreprocessor, if we normalize the inputTree to always have the ownerName (like moduleName) , will ensure addons generate hashes correctly between template and css files.

Root Cause

• embroider passes a different shaped tree, coming through ember-cli-preprocessor-registry that no longer scopes the tree with a moduleName.
• test-packages/embroider-app was not broken because:
  • The app would build fine, without it's moduleName (not the same in classic build where it does provide moduleName in the path.

Suggestion

• I think ModuleSourceFunnel could possibly be removed. If we were to normalize both the inputTree, and stylesTree.

Remove the only!

This seems reasonable to me—thank you both for the fix and for the helpful writeup, @wondersloth!

It looks like the CI config needs a tweak now that one of the test packages has been renamed, but once that's fixed up and the only is removed, this looks good to go!

That seems likely to me! Unfortunately I'm stretched pretty thin and what capacity I do have in this space is focused on charting a migration path to Embroider + v2 addon support, where most of the build work this addon does goes away and is instead handled by bundler plugins like css-loader, rollup-plugin-styles, etc.

Given that, I probably won't invest time myself in improvements like consolidating ModuleSourceFunnel in the near term, but I'd be happy to review a PR if it's something you want to take on 🙂

Specifically, I think these need to be updated for the new package name:

ember-css-modules/.github/workflows/ci.yml

Lines 131 to 134 in 54f7671

	run: yarn workspace octane-addon test
	- name: Octane Addon With Custom moduleName
	run: yarn workspace @my-namespace/octane-addon test

I've found the root cause for this issue in embroider. This fix can land as a bridge between those differences.

• Update with a test demonstrating addon composition in an embroider app.
