transports/webrtc: Implement message framing by thomaseizinger · Pull Request #10 · melekes/rust-libp2p

thomaseizinger · 2022-09-27T03:08:33Z

Description

This continues on #9 which I unfortunately couldn't push to. This PR is based off a branch in rust-libp2p now so @mxinden should definitely have push access and because it targets @melekes's PR he should have push access to :)

Send a RESET flag once a substream gets dropped. This is what mplex does too. I wouldn't know when else to send a RESET flag.
Integrate with StreamMuxer test suite once it is written (Add a crate that provides a test suit for an implementation of StreamMuxer libp2p/rust-libp2p#508)

Change checklist

I have performed a self-review of my own code
I have made corresponding changes to the documentation
I have added tests that prove my fix is effective or that my feature works
A changelog entry has been made in the appropriate crates

…brtc-message-framing

With mxinden/specs@865f4f2 the RESET no longer resets both write and read part of a stream, but only the former.

looks good so far 👍

Writing the muxer test suite turns out to be a bit more complex than I thought it would. I'll see to dedicate most of tomorrow to that.

Might have to first write tests specific to this impl.

This reverts commit 1b0b671.

Looks like the branch has diverged from anton/webrtc-transport. @thomaseizinger do you mind fixing this?

Yep, I should have time for this tomorrow! I got caught up trying to implement stream-resets properly on the other muxers so we can have a standardised test suite but that turns out to be a bigger effort.

Logging these state transitions is no longer really worth it because we have changed the design to have many more functions which would all require logging now.

I also implemented sending of reset flags now for dropped substreams. I think this is now actually complete :)

thomaseizinger · 2022-10-11T08:18:26Z

@mxinden Can you review this please?

melekes · 2022-10-12T11:38:57Z

@mxinden I think you still should be able to review here or in main PR (whatever you prefer).

Updates #2759 See melekes/rust-libp2p#10 and libp2p/specs#412 (comment) Co-authored-by: Pierre Krieger <pierre.krieger1708@gmail.com>

I will review the main branch. Sorry for being a bottleneck here. Thanks @thomaseizinger for driving this all the way from the spec to the implementation! 🙏
