[Splicing] Partial, handle splice_init & splice_ack messages by optout21 · Pull Request #3407 · lightningdevkit/rust-lightning

optout21 · 2024-11-13T14:49:22Z

Handle splice_init & splice_ack messages, without performing splicing. splice_init does not error, but splice_ack returns an error (and neither side continues with splicing).
One next piece for splicing #3298 .
This can come before #3137 .

I have reorganized code, moved most single-channel checks and handling logic into Channel struct from ChannelManager.

Review comments from @wpaulino addressed.

jkczyz

Mostly minor comments and nits, but note that one introduced test is broken.

jkczyz

LGTM. @wpaulino Good to squash the fixups?

optout21 · 2025-03-05T21:05:42Z

Squashed into a single commit, prepared for merging.

Still waiting on CI to start... :(

optout21 · 2025-03-06T08:37:26Z

Somehow CI got mixed up, showing failures for earlier commit... I'm not sure how to re-trigger.

Commit ID is different. I know the issue being reported (conflict caused by #3016) but fixed previously.

optout21 · 2025-03-06T08:38:33Z

Did a commit amend & force push, let's see CI's response...

optout21 · 2025-03-06T12:56:21Z

For some reason (which I don't understand), when in the CI this PR branch is merged onto current main, a bunch of previous rebase merges get reverted, and compilation fails. Even though the PR branch was rebased to recent and has no conflicts. I have recreated the commit completely anew, hopefully this helps.

Github shows that your branch is 33 commits behind. If I rebase your PR on upstream main, I can reproduce the CI failure with RUSTFLAGS="--cfg=splicing" cargo +1.63.0 check -p lightning. Seems you need to account for #3594.

Handle the initial splice negotiation, without continuing to transaction negotiation: - `splice_channel()` for initiating splicing - handling of `splice_init` and `splice_ack` messages, with checks - `splice_ack` always fails (use case still imcomplete) - A test to go through the use case (`test_v1_splice_in`)

Rebased and fixed the compilation error locally. CI running now.
