Missing license text for test files copied from dotnet-assets

[musicinmybrain]

Describe the bug

Certain files in tests/data/ are copied from https://github.com/dotnet/runtime-assets.

zip2/tests/data/README.md

Lines 1 to 6 in 102e311

	A few assets in directory is copied from [dotnet-assets].
	- [`deflate64.zip`](./deflate64.zip) is originally at https://github.com/dotnet/runtime-assets/blob/95277f38e68b66f1b48600d90d456c32c9ae0fa2/src/System.IO.Compression.TestData/ZipTestData/compat/deflate64.zip
	- [`folder/binary.wmv`](./folder/binary.wmv) is originally at https://github.com/dotnet/runtime-assets/tree/95277f38e68b66f1b48600d90d456c32c9ae0fa2/src/System.IO.Compression.TestData/ZipTestData/refzipfolders/normal/binary.wmv
	[dotnet-assets]: https://github.com/dotnet/runtime-assets

These are therefore covered by the overall license of that repository, https://github.com/dotnet/runtime-assets/raw/95277f38e68b66f1b48600d90d456c32c9ae0fa2/LICENSE.TXT.

This is MIT, just like the license of this crate, but the MIT license terms require the copyright and permission notices (i.e., the license text) to be “included in all copies or substantial portions of the Software.”

Therefore, a copy of the license file for dotnet/runtime-assets, with the correct copyright statement, should be committed to this repository.

To Reproduce

1. Examine https://github.com/zip-rs/zip2/tree/v1.3.0/tests/data
2. Observe that two files are attributed to https://github.com/dotnet/runtime-assets.
3. Observe that no license text is present for these two files.

Expected behavior
All required license texts are present for all files.

Additional context

A reasonable fix would be to add the contents of https://github.com/dotnet/runtime-assets/raw/95277f38e68b66f1b48600d90d456c32c9ae0fa2/LICENSE.TXT, perhaps converted from CRNL to NL line terminations with dos2unix or similar, to a file in tests/data/. I suggest tests/data/LICENSE-dotnet-assets.

You could additionally append to tests/data/README.md something like:

See [`LICENSE-dotnet-assets`](./LICENSE-dotnext-assets), which contains the text from https://github.com/dotnet/runtime-assets/raw/95277f38e68b66f1b48600d90d456c32c9ae0fa2/LICENSE.TXT.

I would be happy to open a trivial PR to do this, but I am not willing to set up GPG commit signing just for that purpose, so I’m just filing this issue and moving on instead.

Fixed. There's actually one other file, tests/data/lin-ub_iwd-v11.zip that was provided in a pull request, and the authors aren't credited so I don't know who owns it. It's a version of "Unfinished Business for Icewind Dale", so if anyone claims copyright on it it'll be Interplay Entertainment; but I don't know whether any of their code or art is present so that such a claim would be legitimate. If you happen to be able to find out, please feel free to open another issue!

I appreciate the follow-up, but it seems like the new files LICENSE.deflate64.zip.txt and LICENSE.binary.wmv.txt are empty. Am I missing anything?

It looks like tests/data/lin-ub_iwd-v11.zip is exactly the release archive from https://github.com/Gibberlings3/iwd_unfinished_business/releases/tag/v11. A quick survey doesn’t reveal any obvious game content from the commercial Icewind Dale game in this mod—although it is hard to be entirely certain—but on the other hand, there is no declared license for the original content in the mod, so it could still be problematic on that basis alone.

Thanks; I've updated the empty files (still not sure how they ended up being committed empty) and, in the case of the Icewind Dale mod, added a brief attribution and a copy of the project's own relevant notices.
