Thanks for working on this!

Looking at the example and code it looks like this doesn't follow the intent of #2052 which wants the attach command to support reading multiple attestations from a single file in the in-toto bundle format.

The expected behavior is that a single file would have multiple attestations contained within it (one per line) and that attach should read and attach all of them.

e.g.

{ "payloadType": "application/vnd.in-toto+json", "payload": "a...", "signatures": [w...] }
{ "payloadType": "application/vnd.in-toto+json", "payload": "b...", "signatures": [w...] }

The behavior here, letting the user specify multiple files, does seem useful though. I wouldn't be surprised if some users would like this capability, it's just not quite what I was looking for in #2052.

WDYT?

developer-guy · 2022-07-21T13:54:01Z

Oh, thanks, @TomHennen, we couldn't understand the issue at first, but now we are okay with the idea and will fix it soon, but @dlorenc, what do you think about this PR? It seems useful for people who might want to add multiple attestation files.

Seems fine. When we support bundles, would we just detect them in the same file/flag or would that be different?

In this PR, UX will remain the same, just add knowledge about the jsonlines file for attestation bundles.

Thanks, this seems to work well! :)

Is there a place to add a note that "attach attestation supports files using the in-toto bundle format" or something like that?

nit, instead of 'signedPayloads', should this be 'filePaths' ?

thank you, updated.
