Exercise installed resolver and download hooks through bootstrap and check artifact outputs and build-order metadata for both source profiles

Closes: #1420

[coderabbitai]

Walkthrough

The change registers a setuptools project override hook, adds settings for the hook-sdist and hook-prebuilt source profiles, and implements downloading a prebuilt wheel through download_source. End-to-end tests run bootstrap for both profiles and verify generated artifacts, hook logs, and build-order metadata.

Estimated code review effort: 3 (Moderate) | ~20 minutes

Merge Risk: Low · up to 5b2b0

The new setuptools hook registration in the shared e2e fixture could break other end-to-end tests that install the fixture and download setuptools without a configured source. Confirm that no existing consumer reaches that path, or move the override into a dedicated fixture. The added hook-profile tests themselves look sound, and production code is not affected.

Full details: Title check

Explanation

The title "test(e2e): cover hook source profiles" matches the main change. The PR adds end-to-end tests that exercise the installed resolver and download hooks for the hook-sdist and hook-prebuilt source profiles, and checks their artifact outputs and build-order metadata. The title is concise and specific, and it follows a conventional commit style.

Full details: Description check

Explanation

The description states that the PR exercises installed resolver and download hooks through bootstrap, checks artifact outputs and build-order metadata for both source profiles, and closes issue #1420. This matches the changeset, which adds e2e cases for hook-sdist and hook-prebuilt and the related fixture configs and plugin code.

Explanation

Issue #1420 asks for two e2e cases. (1) hook-prebuilt with index_url and a download_source hook. The diff adds case 6 in e2e/test_build_source_config.sh. It bootstraps setuptools==75.8.0 with e2e/source_settings_hook_prebuilt. The new hooks.py download_source hook and the setuptools.yaml index_url setting cover the hook and index configuration. The case checks the downloaded wheel, the log line 'download_source hook downloading setuptools==75.8.0', and build-order.json fields (version, source_provider=hook-prebuilt, source_url_type=prebuilt, prebuilt=true, files.pythonhosted.org URL). (2) hook-sdist with a get_resolver_provider and/or download_source hook. The diff adds case 5. It installs github_override_example and bootstraps stevedore with source_settings_hook_sdist. It checks the wheel and sdist, the log line 'stevedore: found get_resolver_provider override', and build-order.json fields (version, source_provider=hook-sdist, source_url_type=override, prebuilt=false, GitHub archive URL). Both cases check hook calls and build-order metadata, as the issue requires. The index_url setting is set in the config, not asserted directly in build-order.json. The hook plugin source is outside the diff; the get_resolver_provider log line is taken from existing plugin code, not re-read.

Explanation

All changed files support the linked test objectives. e2e/test_build_source_config.sh adds the two hook cases and their assertions. e2e/source_settings_hook_sdist/stevedore.yaml and e2e/source_settings_hook_prebuilt/setuptools.yaml select the hook profiles needed by those cases. e2e/fromager_hooks/src/package_plugins/hooks.py adds the download_source hook that the hook-prebuilt case calls. e2e/fromager_hooks/pyproject.toml registers the fromager.project_overrides entry point that connects that hook to setuptools. The header comment update in the test script only describes the new cases. No unrelated production code or behavior change was identified in the summary.

Do not register a DownloadedSource-returning hook for setuptools in the shared fixture.

With this fixture installed, a setuptools download that has no configured source resolver calls download_source in package_plugins.hooks. That hook returns DownloadedSource. The legacy dispatcher in src/fromager/sources.py:119-122 accepts only a pathlib.Path and raises ValueError for any other type, so the bootstrap fails.

The hook-prebuilt path accepts DownloadedSource. Its passing case does not show that legacy setuptools downloads still work.

Check whether any existing consumer of the shared fixture bootstraps setuptools without a source configuration. If one does, move this override into a dedicated fixture that only the hook-prebuilt tests install.

Valid. I will move the override into a dedicated fixture used only by the hook prebuilt test
