Fixes #60.

NormalizeEcosystem now maps crates.io to cargo. ConanCenter, SwiftURL and GitHub Actions had the same problem, and so did the githubactions PURL type, so they're aliased too. The new test checks every entry in osvEcosystemNames, both the OSV name and the PURL type.

I checked it against vulns (which pins purl v0.1.24) with a synthetic advisory for each of the four: FixedVersion and IsVersionAffected miss all of them before this change and match after it. The vulns regression test the issue asks for needs a purl release first, so it isn't included here.

Summary by CodeRabbit

• Improvements
  • Ecosystem names are recognized and normalized consistently across OSV and package URL formats. Supported aliases include crates.io for Cargo, github actions and githubactions for GitHub Actions, conancenter for Conan, and swifturl for Swift. Existing aliases for Go, RubyGems, and Composer continue to be supported.

Walkthrough

The ecosystem alias map now recognizes additional names for GitHub Actions, Cargo, Conan, and Swift. Tests cover normalization consistency, PURL-string parsing, and invalid Swift identities.

Changes: Ecosystem alias normalization

Layer / File(s)	Summary
Add ecosystem aliases and test normalization ecosystem.go, ecosystem_test.go	Added aliases for githubactions, github actions, crates.io, conancenter, and swifturl. Tests cover normalization consistency across OSV names and PURL types, PURL-string inputs, and invalid Swift identities for swift and SwiftURL.

Change: Bug fix · Severity of issue fixed: Medium

Suggested reviewers: andrew

Merge Risk: Minimal · up to 107f3

The new aliases use the existing conversion paths. No material merge-blocking risk is established.

Security architecture risk: Minimal · up to 107f3

The additional names resolve to existing ecosystem implementations. The inspected construction paths retain their identity checks and failure behavior, with no material security risk identified from this change.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated exposure is changed package-identity output for callers supplying the added aliases. Canonical ecosystem inputs already reached the same implementation branches. The supplied graph does not establish the full downstream consumer scope.

Trust Boundaries and Controls

• inferred — In the inspected paths, externally supplied naming variants enter existing canonical dispatch rather than bypassing it. SwiftURL gains the Swift-specific identity checks; githubactions gains the same repository splitting already used by github-actions. No weakened identity control was identified in this comparison.

Full details: Out of Scope Changes check

Explanation

The additional aliases for ConanCenter, SwiftURL, GitHub Actions, and the githubactions PURL type normalize OSV names to their corresponding PURL ecosystems. This extends the same normalization behavior requested by issue #60. The added normalization and PURL builder tests cover these aliases. No unrelated changes are evident in the reviewed files or supplied change summary.

Full details: Linked Issues check

Explanation

Issue #60 requests the crates.io alias while preserving the cargo to crates.io OSV conversion. ecosystemAliases maps crates.io to cargo, and osvEcosystemNames retains the cargo mapping. TestNormalizeEcosystemAcceptsOSVNames checks that OSV names and PURL types normalize to the same ecosystem. The requested regression test in vulns is not included. The PR description confirms that the test is deferred. This leaves the requirement to test matching returned OSV records using the PURL type unmet.

Resolution

Add a regression test in git-pkgs/vulns that verifies returned OSV records with ecosystem crates.io match the cargo PURL type for FixedVersion and IsVersionAffected.

Full details: Docstring Coverage

Explanation

Docstring coverage is 0.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 4 functions across 2 files.

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

[andrew]

Thanks for this, and for extending it past crates.io to the other OSV names. The loop over osvEcosystemNames is a good test to have.

One thing needs covering before it goes in. splitNamespace in makepurl.go switches on NormalizeEcosystem(ecosystem), so the new aliases also change what MakePURL and MakePURLString return, and nothing tests that:

• githubactions now reaches the github-actions case, so actions/cache/restore is split into namespace actions and name cache. Before this change it fell through the switch unsplit.
• SwiftURL now goes through splitSwift, which rejects identifiers it can't represent.
• crates.io and ConanCenter now build cargo and conan PURLs.

Please add rows to the MakePURL table in ecosystem_test.go (next to the existing github-actions path row) for githubactions with a sub-path, GitHub Actions, crates.io, ConanCenter and SwiftURL.

[charlie-morrison]

Added in 107f3f9. The MakePURLString table now has rows for githubactions with a sub-path, GitHub Actions, crates.io, ConanCenter and SwiftURL, next to the github-actions path row. All five fail on main (pkg:crates.io/serde, pkg:github actions/actions%2Fcheckout, unsplit actions%2Fcache%2Frestore and so on).

For the splitSwift rejections I ran the existing TestMakePURLRejectsInvalidSwiftIdentity list for SwiftURL as well as swift, rather than adding a nil row to a table that expects a PURL back. On main all 22 identities come back as pkg:swifturl/... PURLs.
