This is a bit of a weird error @Jake-Shadle :

tage: license_check

 Aug 29 14:29:19.136 ERRO detected an exception not explicitly allowed, exception: LLVM-exception, crate: wasi@0.5.0

 Aug 29 14:29:19.137 ERRO encountered 1 license errors

[repi]

Oh I see it is the new wasi crate that has a fairly complex license definition: Apache-2.0 WITH LLVM-exception OR Apache-2.0 OR MIT

[Jake-Shadle]

Hah, that is weird, but you can just add LLVM-exception to the license allow list, which is what we already have in ark.

[repi]

Yes, but we are technically parsing the license wrong right? Apache-2.0 WITH LLVM-exception should be one of the detected licenses, not just LLVM-exception.

[Jake-Shadle]

For simplicity I just consider exceptions in isolation, but maybe that is wrong. It's easy enough to fix!

[repi]

Thanks for confirming, I've filed #22 to track that and in this PR will at least temporarily add that exception to the license allow list.
