The license check failed, which is weird as we just bump up the version.

--- Starting license compliance check ---
license BSD-2-Clause not in allow-only licenses was found for package Pygments:2.20.0
make: *** [Makefile:182: client-license-check] Error 1
Error: Process completed with exit code 2.

[jbonofre]

@flyrain I hope the license didn't change on a minor version bump 😄

@flyrain I hope the license didn't change on a minor version bump 😄

That's what I thought as well.

So the older version has following:

 Pygments               2.19.2          BSD License

And the newer version has following:

Pygments               2.20.0          BSD-2-Clause

We are using following to check what are allowed:

allow-only = "Apache;BSD License;BSD-3-Clause;ISC;MIT;Mozilla Public License;PSF-2.0;Python Software Foundation License;The Unlicense"

Looking at this https://github.com/pygments/pygments, it had been BSD-2-Clause for years. The reason on why this happened is due to non PEP 639 compatible metadata which got fixed in pygments/pygments@4a73776 (and this is in 2.20.0 release).

Then looking at dependency tree, this is added by pytest. Also, with the recent discussion of using rich for better UX for CLI, rich is using Pygments as well.

Per this page, https://www.apache.org/legal/resolved.html#category-a, BSD-2-Clause is allowed in an ASF Project? We will need to update our checker.

Yes, I was looking at it as well. Let me quickly fix it.

Here is the PR, #4100

[MonkeyCanCode]

BTW, we can't merge this one. I was looking into this one for pyiceberg last night: apache/iceberg-python#3209

[flyrain]

Let us put a change request then.

[flyrain]

@MonkeyCanCode is investigating pygments/pygments#3076

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
