📝 Walkthrough

Walkthrough

Adds Oracle GraalVM as a JVM vendor. The implementation fetches Oracle release metadata, filters supported packages, parses modern archive names, records checksums, and registers the vendor globally.

Changes

Oracle GraalVM support

Layer / File(s)	Summary
Release metadata and filename parsing src/jvm/vendor/oracle_graalvm.rs	Defines release response models and parses supported Linux, macOS, and Windows archive names for x64 and aarch64 builds. Tests cover valid and invalid names.
Release retrieval and JVM mapping src/jvm/vendor/oracle_graalvm.rs	Fetches release data in parallel, excludes Enterprise and innovation entries, processes Core packages, normalizes metadata, and records SHA256 checksums.
Global vendor registration src/jvm/vendor/mod.rs	Publishes the Oracle GraalVM module and adds OracleGraalVM to the global vendor registry.

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

Poem

A rabbit hops through release rows bright,
Parses each archive left and right.
Core builds bloom with checksums neat,
Enterprise entries face retreat.
GraalVM joins the vendor line—
A carrot toast to code so fine!

Greptile Summary

This PR restores the Oracle GraalVM vendor using Oracle’s JSON download index.

• Registers oracle-graalvm in the JVM vendor list.
• Fetches release metadata in parallel and maps Core archives into normalized JvmData records.
• Adds filename parsing tests for supported operating systems and architectures.

Confidence Score: 5/5

The PR appears safe to merge with no concrete changed-code failure established.

The restored vendor follows existing normalization and partial-fetch conventions, and the investigated parsing, metadata mapping, and registration paths revealed no reachable contract violation.

Important Files Changed

Filename	Overview
src/jvm/vendor/mod.rs	Registers the restored Oracle GraalVM module and vendor implementation.
src/jvm/vendor/oracle_graalvm.rs	Implements Oracle JSON metadata retrieval, release mapping, checksum handling, filename parsing, and focused parser tests.

145-197: 📐 Maintainability & Code Quality | 🔵 Trivial | ⚡ Quick win

Add unit tests for map_file and map_release.

Only meta_from_name has test coverage. map_file (checksum extraction, innovation-release filtering) and map_release (Core package selection) contain pure logic that does not require network access, yet neither is covered by tests. Add tests that construct FileData/PackageData/ReleaseData values directly and assert on checksum extraction, innovation-release skipping, and Core-only filtering.

Also applies to: 233-305
