Add VSS Support in ldk-node by G8XSU · Pull Request #158 · lightningdevkit/ldk-node

G8XSU · 2023-08-18T07:12:42Z

Note:
This PR does not add full support of VSS, there will be additional PR's for some of the changes.
Currently it introduces only VssKVStore which is major chunk of code.

We will call it full support only once we make changes to public api for ldk-node.

Note on testing:

Running a Java WAR file within a Rust test is not a straightforward process, as the execution of a Java WAR typically requires a Java runtime, which can not be natively managed by Rust.
Currently it is tested against a local instance of VSS. But we will be testing this as part of our CI pipeline as discussed in sync, currently working on it.
Alternative to env-var was feature-gate, but I didn't see much reason to introduce new feature for this test and it could be confusing. Setting env-var to any value will result in test-failure if vss doesn't work properly or it is not a correct endpoint. So we can easily verify this.

@tnull for review.

Did a first pass, excuse the delay.

What is our current thinking about landing this in conjuction with follow-ups? Do we want to land this and hide the code behind a cfg until it's ready to be published, or should we keep this PR open until all follow-ups are ready? As the changes shouldn't overlap too much with the rest of the codebase, we could also do a feature-branch for this and merge it into main once it's ready?

Regarding landing this PR or related PR's to VSS.

I do want to merge them independently into main so that we close on things.
Since there was no public interface/code which is exposed, i did not feel the need to feature-gate it. I will feature-gate if pub interface is exposed.

Or expose public interface only once we are ready. Let me know if that works.

Yeah, that generally works for me, but let's feature-gate it (behind vss or vss-store?) and include respective CI checks so that we actually can test it going forward.

Failing test is fixed in #184.

I'm good with squashing the fixups and rebasing.

LGTM, should be ready to go, just two really minor nits.
