Download > derive clarified_version from the selected git ref

[soimkim]

SemVer checkout used the user hint (e.g. -c 15.0) as clarified_version. Use the matched tag instead so android-15.0.0_r1 clarifies to 15.0.0.

📝 Walkthrough

Walkthrough

The download flow now preserves clarified versions from selected Git references, improves archive and URL version parsing, and clears stale Git errors after successful fallback downloads. Tests cover Android, npm, Maven, and Git clone resolution.

Changes

Version resolution and download fallback

Layer / File(s)	Summary
Version-hint parsing and validation src/fosslight_util/download.py, tests/test_download_version_hint.py	Parsing now recognizes embedded three-part versions, version-only archive stems, Android release hints, and valid Maven version hints.
Reference matching and clarified checkout versions src/fosslight_util/download.py, tests/test_decide_checkout.py	Git reference matching accepts @ boundaries and derives clarified versions from selected Android and npm-scoped package tags.
Download result propagation and validation src/fosslight_util/download.py, tests/test_decide_checkout.py, tests/test_download_version_hint.py	The orchestration preserves Git-derived clarified versions, clears stale Git errors after fallback success, and validates Git cloning and Maven resolution.

Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🔵 Low · up to a5837

In an edge case with multiple matching tags at the same highest patch level, the download may choose different source references across runs, leading to inconsistent package contents. The change is otherwise mergeable with explicit owner awareness or a follow-up to make tie-breaking deterministic.

710-711: 🎯 Functional Correctness | 🟠 Major | ⚡ Quick win

Resolve equal highest patches deterministically.

If checkout_to is 0.3 and two scoped tags both resolve to 0.3.6, this max() call selects the first tied item from a set-derived list. The selected Git reference can vary by process and can clone a different package tag.

Filter for the highest patch first. Then apply the same stable (len(ref), ref.lower()) ordering used for exact matches.

Proposed fix

-        ref = max(same_maj_min, key=lambda x: x[1])[0]
+        highest_patch = max(patch for _, patch in same_maj_min)
+        ref = min(
+            (candidate for candidate, patch in same_maj_min if patch == highest_patch),
+            key=lambda candidate: (len(candidate), candidate.lower()),
+        )
         return True, ref, clarified_version_from_oss_version(ref)
