[ANE-1349] Binary discovery support for whl files - #1750
Conversation

WalkthroughThe binary discovery pipeline now uses Merge Risk: 🟡 Moderate · up to Wheel scanning can incorrectly associate dependencies when archives contain misleading .dist-info directory names, potentially showing a false pip dependency in the UI. Tighten the directory-name match and add regression coverage before merging. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Around line 83-89: Update findDistInfoFolder to match only directory names
that end with the exact “.dist-info” suffix, removing any trailing directory
separator before checking; do not use substring matching that accepts names such
as “.dist-info-backup”. Add a regression fixture containing both a valid
.dist-info directory and a misleading similarly named directory.

I think the code is good, but I want to raise one thing.
The dependencies found by this PR don't show their path, and I think this is going to be confusing to a customer. For example, in this screenshot you can see where the jar file is from but not the pip dep:
The only solution that I can think of is to make each .whl file its own source unit and set the OriginPaths field in it. If you do that, then you get the path:
(I did this by just creating some SourceUnits and POSTing them directly to Core. I didn't write any code)
I'm not sure if this is a deal-breaker, but it's definitely a nice to have for this feature

The metadata file contains the readme, which can contain a :. So this will break for any readme that contains a :
An example is the sympy readme: https://files.pythonhosted.org/packages/a2/09/77d55d46fd61b4a135c444fc97158ef34a095e5681d0a6c10b75bf356191/sympy-1.14.0-py3-none-any.whl
If you unzip that, you see lots of lines in sympy-1.14.0.dist-info/METADATA that contain :, and those will become keys
I think the fix is to just send the header to parseMetadata, which is everything before the first blank line
The value can also be multi-line, like this:

We should probably also parse that properly
The spec for this is apparently RFC 822, which is kind of dense. https://datatracker.ietf.org/doc/html/rfc822#section-3.2

Overview
Given a whl file, we need to identify the dependency that is associated with it. Whl files are zip files that can be unzipped. They all require a “METADATA” file in their dist-info directory.
This PR adds the capability to scan these .whl files on top of our existing binary analysis logic which only supported JAR files separately. One thing to note: JAR file analysis creates user defined deps rather than
mvndeps so the logic needed to be extended a bit for.whlfiles to createpipdeps instead of user defined deps.Acceptance criteria
Testing plan
Automated testing has been added. For manual testing, copying the automated testing fixtures, or downloading any .whl file and running a fossa analyze on it should suffice.
fossa analyze . --experimental-enable-binary-discovery --debugRisks
Should be low risk since it's extending a feature and it's behind an experimental flag
Metrics
Some logging has been added, if that surfaces in Datadog, we can monitor failures
