Description

libp2p/rust-yamux#176 enables auto-tuning for the Yamux stream receive window. While preserving small buffers on low-latency and/or low-bandwidth connections, this change allows for high-latency and/or high-bandwidth connections to exhaust the available bandwidth on a single stream.

Using the libp2p perf benchmark tools (60ms, 10Gbit/s) shows an improvement from 33 Mbit/s to 1.3 Gbit/s in single stream throughput.

See libp2p/rust-yamux#176 for details.

To ship the above Rust Yamux change in a libp2p patch release (non-breaking), this pull request uses yamux v0.13 (new version) by default and falls back to yamux v0.12 (old version) when setting any configuration options. Thus default users benefit from the increased performance, while power users with custom configurations maintain the old behavior.

Notes & open questions

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

Great work! Some minor nits, nothing blocking (apart from a yamux release!)

* ci: unset `RUSTFLAGS` value in semver job

* deps(webrtc): bump alpha versions

Bumps versions of `libp2p-webrtc` and `libp2p-webrtc-websys` up one minor version.

Fixes: libp2p#4953.

* refactor(connection-limits): make `check_limit` a free-function

Pull-Request: libp2p#4958.

* chore(webrtc-utils): bump version to allow for new release

We didn't bump this crate's version despite it depending on `libp2p_noise`. As such, we can't release `libp2p-webrtc-websys` at the moment because it needs a new release of this crate.

Pull-Request: libp2p#4968.

* feat(webrtc-websys): hide `libp2p_noise` from the public API

Currently, `libp2p-webrtc-websys` exposes the `libp2p_noise` dependency in its public API. It should really be a private dependency of the crate. By wrapping it in a new-type, we can achieve this.

Pull-Request: libp2p#4969.

* fix(kad): iterator progress to be decided by any of new peers

* feat(server): support websocket

Pull-Request: libp2p#4937.

* feat(swarm): implement `Copy` and `Clone` for `FromSwarm`

We can make `FromSwarm` implement `Copy` and `Close` which makes it much easier to

a) generate code in `libp2p-swarm-derive`
b) manually wrap a `NetworkBehaviour`

Previously, we couldn't do this because `ConnectionClosed` would have a `handler` field that cannot be cloned / copied.

* deps: bump wasm-bindgen-test from 0.3.38 to 0.3.39

Pull-Request: libp2p#4975.

* fix(kad): don't assume `QuerId`s are unique

We mistakenly assumed that `QueryId`s are unique in that, only a single request will be emitted per `QueryId`. This is wrong. A bootstrap for example will issue multiple requests as part of the same `QueryId`. Thus, we cannot use the `QueryId` as a key for the `FuturesMap`. Instead, we use a `FuturesTupleSet` to associate the `QueryId` with the in-flight request.

Related: libp2p#4901.
Resolves: libp2p#4948.

Pull-Request: libp2p#4971.

* fix(webrtc example): clarify idle connection timeout

When I ran the `example/browser-webrtc` example I discovered it would break after a ping or two.
The `Ping` idle timeout needed to be extended, on both the server and the wasm client, which is what this PR fixes.
I also added a small note to the README about ensuring `wasm-pack` is install for the users who are new to the ecosystem.

Fixes: libp2p#4950.

# Description

Fixes #5996

https://github.com/libp2p/rust-libp2p/releases/tag/libp2p-v0.53.0
https://github.com/libp2p/rust-libp2p/blob/master/CHANGELOG.md

## Integration

Nothing special is needed, just note that `yamux_window_size` is no
longer applicable to libp2p (litep2p seems to still have it though).

## Review Notes

There are a few simplifications and improvements done in libp2p 0.53
regarding swarm interface, I'll list a few key/applicable here.

libp2p/rust-libp2p#4788 removed
`write_length_prefixed` function, so I inlined its code instead.

libp2p/rust-libp2p#4120 introduced new
`libp2p::SwarmBuilder` instead of now deprecated
`libp2p::swarm::SwarmBuilder`, the transition is straightforward and
quite ergonomic (can be seen in tests).

libp2p/rust-libp2p#4581 is the most annoying
change I have seen that basically makes many enums `#[non_exhaustive]`.
I mapped some, but those that couldn't be mapped I dealt with by
printing log messages once they are hit (the best solution I could come
up with, at least with stable Rust).

libp2p/rust-libp2p#4306 makes connection close
as soon as there are no handler using it, so I had to replace
`KeepAlive::Until` with an explicit future that flips internal boolean
after timeout, achieving the old behavior, though it should ideally be
removed completely at some point.

`yamux_window_size` is no longer used by libp2p thanks to
libp2p/rust-libp2p#4970 and generally Yamux
should have a higher performance now.

I have resolved and cleaned up all deprecations related to libp2p except
`BandwidthSinks`. Libp2p deprecated it (though it is still present in
0.54.1, which is why I didn't handle it just yet). Ideally Substrate
would finally [switch to the official Prometheus
client](paritytech/substrate#12699), in which
case we'd get metrics for free. Otherwise a bit of code will need to be
copy-pasted to maintain current behavior with `BandwidthSinks` gone,
which I left a TODO about.

The biggest change in 0.54.0 is
libp2p/rust-libp2p#4568 that changed transport
APIs and enabled unconditional potential port reuse, which can lead to
very confusing errors if running two Substrate nodes on the same machine
without changing listening port explicitly.

Overall nothing scary here, but testing is always appreciated.

# Description

Fixes #5996

https://github.com/libp2p/rust-libp2p/releases/tag/libp2p-v0.53.0
https://github.com/libp2p/rust-libp2p/blob/master/CHANGELOG.md

## Integration

Nothing special is needed, just note that `yamux_window_size` is no
longer applicable to libp2p (litep2p seems to still have it though).

## Review Notes

There are a few simplifications and improvements done in libp2p 0.53
regarding swarm interface, I'll list a few key/applicable here.

libp2p/rust-libp2p#4788 removed
`write_length_prefixed` function, so I inlined its code instead.

libp2p/rust-libp2p#4120 introduced new
`libp2p::SwarmBuilder` instead of now deprecated
`libp2p::swarm::SwarmBuilder`, the transition is straightforward and
quite ergonomic (can be seen in tests).

libp2p/rust-libp2p#4581 is the most annoying
change I have seen that basically makes many enums `#[non_exhaustive]`.
I mapped some, but those that couldn't be mapped I dealt with by
printing log messages once they are hit (the best solution I could come
up with, at least with stable Rust).

libp2p/rust-libp2p#4306 makes connection close
as soon as there are no handler using it, so I had to replace
`KeepAlive::Until` with an explicit future that flips internal boolean
after timeout, achieving the old behavior, though it should ideally be
removed completely at some point.

`yamux_window_size` is no longer used by libp2p thanks to
libp2p/rust-libp2p#4970 and generally Yamux
should have a higher performance now.
