bug: `--non-spdx` behaves differently between `list` and `check`

[domWalters]

What happened:

1. When you run grant list it returns the full list of all licenses (SPDX and non-SPDX).
2. When you run grant list --non-spdx it returns the list of all non-SPDX licenses.
3. When you run grant check it checks the SPDX licenses ONLY.
4. When you run grant check --non-spdx it checks the non-SPDX licenses ONLY.

Point 3 here is a problem. I assumed that because grant list worked on all licenses, that grant check would as well.

What you expected to happen:

I expected grant check to run on the same licenses that grant list showed me, no matter the value of non-spdx.

Steps to reproduce the issue:
Run grant on the SBOM below (note: I have removed the metadata.component field, but grant was still happy to run on this).

Syft generated SBOM

For completeness, this SBOM was generated using syft on a Python .venv which was created from this requirements.txt:

# Direct
requests==2.18.4

# Inherited
certifi==2025.1.31
chardet==3.0.4
idna==2.6
urllib3==1.22

Note: Yes, I'm aware these versions are ancient. This was used to demo the functionality of syft / grype / grant to senior colleagues so I can push for adoption of the whole suite of tools 😊

FYI, syft does not correctly identify the licenses of these versions of:

• requests
  • "Apache 2.0" instead of "Apache-2.0"
• chardet
  • "LGPL" instead of "LGPL-2.1-only" (I think)
• idna
  • "BSD-like" instead of "BSD-3-Clause"

But I've put that down to the licenses in those repos not being the exact SPDX license match.

requests and chardet have since changed their LICENSE text to more closely match the actual license, so I imagine those should match properly in newer versions.

Anything else we need to know?:

Thanks @domWalters! Also I appreciate the callout for the licenses not exactly matching for those packages. I'll take a look over in syft when I have a second.

I'll get this reported bug fixed asap.

Thank you for trying out the tools!

For some stuff coming down the pipe in grant please see:
#176

Providing one concrete example:

This license is "Apache 2.0" for some reason, not "Apache-2.0": https://github.com/psf/requests/blob/v2.18.4/LICENSE

I didn't try with the newest requests but it looks like they changed the license since the version I'm using, so it might get the right name in the newest version:

https://github.com/psf/requests/commits/main/LICENSE

---

One final thing I noticed, that is already reported.

syft on a python project only gets licenses if you call it on a venv. Calling on the requirements.txt file isn't enough. I think this should at least be documented somewhere. The requirements.txt is listed against python in the list of stuff you can call against, but it technically doesn't give you everything at the moment.

This looks resolved by the evaluation refactor since 0.2.6. On current main the --non-spdx flag no longer exists on either subcommand, and check now evaluates every license in pkg.Licenses (in grant/evaluation.go evaluatePackage), with non-SPDX licenses falling through to IsLicensePermitted rather than being skipped.

Quick repro against a 2-package SBOM (one SPDX MIT, one non-SPDX Some Proprietary License):

• grant list shows both (MIT = Low, "Some Proprietary License" = Unknown).
• grant check with an allow-list of [MIT] reports 1 denied, 1 allowed and denies the non-SPDX package.

So check now evaluates the same license set list shows, which is the parity this issue asked for. Might be worth closing as resolved-by-refactor unless I am missing a case.
