Get NuGet package versions from federated PURL version data in https://github.com/aboutcode-data/ #2418
Description

Hi @keshav-space,
I investigated the example package and traced the empty result to NuGet registration pagination.
The package
pkg:nuget/Microsoft.WindowsDesktop.App.Runtime.win-arm64currently has 138 versions upstream across three registration pages:page/5.0.0/7.0.11.json— 64 versionspage/7.0.12/10.0.2.json— 64 versionspage/10.0.3/10.0.12.json— 10 versions
The issue is that
fetchcode.package_versions.nuget_extract_versions()only consumed inlineitemsfrom the registration index. For packages with large release histories, NuGet omits inlineitemsand points to external pages through@id, which were previously unvisited.Contributor @codewithfourtix recently submitted a PR in fetchcode addressing this exact pagination behavior: aboutcode-org/fetchcode#214.
Once PR #214 is merged and consumed in VulnerableCode,
fetchcode.package_versions.versions("pkg:nuget/Microsoft.WindowsDesktop.App.Runtime.win-arm64")resolves all 138 versions directly from NuGet.Would resolving this via fetchcode #214 cover #2418, or is the intended behavior still to add a fallback to federated
aboutcode-dataPURL repositories for packages whose versions are genuinely unavailable upstream?Hi @keshav-space, I’d like to work on this issue. I’ll first look into the current NuGet version-fetching flow and how the AboutCode Data PURL version data can be used as a fallback. If there are any specific edge cases or expected behavior I should keep in mind, please let me know.
Reacted by Hardik KReacted by Hardik KThis should be fixed by aboutcode-org/fetchcode#214. The registration index for this package links to external pages instead of inlining versions, which fetchcode didn't follow. With #214,
versions("pkg:nuget/Microsoft.WindowsDesktop.App.Runtime.win-arm64")returns 138 versions (5.0.0 to 10.0.12) instead of 0.
Fetchcode returns no version for
pkg:nuget/Microsoft.WindowsDesktop.App.Runtime.win-arm64, but we have all the versions for this package in https://github.com/aboutcode-data/purls-nuget-0128/blob/main/nuget-0182/Microsoft.WindowsDesktop.App.Runtime.win-arm64/purls.yml.This issue impacts our ability to unfurl NuGet versions and flag ghost NuGet packages.
