Most of this is trivial, apart from the rename of the `clippy::derive_hash_xor_eq` lint to `clippy::derived_hash_with_manual_eq`.
Instead of allowing that lint, we manually implement `PartialEq` and add a comment why the difference between the `PartialEq` and `Hash` implementations are okay.
Previously, we used the full reference to the `OutEvent` of the `ConnectionHandler` in all implementations of `NetworkBehaviour`. Not only is this very verbose, it is also more brittle to changes. With the current implementation plan for #2824, we will be removing the `IntoConnectionHandler` abstraction. Using a type-alias to refer to the `OutEvent` makes the migration much easier.
Previously, inbound connections that happened to resolve to our own `PeerId` were reported as `WrongPeerId`. With this patch, we now report those in a dedicated `LocalPeerId` error.

The gossipsub tests are calling lifecycle functions of the `NetworkBehaviour` that aren't meant to be called outside of `Swarm`. This already surfaced as a problem in https://github.com/libp2p/rust-libp2p/pull/3327 and it is coming up again in https://github.com/libp2p/rust-libp2p/pull/3254 where `new_handler` gets deprecated.
Try to mitigate that by constructing a dummy handler instead. Functionally, there is no difference as in both cases, the given handler has never seen a connection.
Storing `NetworkBehaviourAction`s within the behaviour is more flexible than only storing `OutEvent`s. Additionally, I find expression-oriented code easier to reason about because it typically doesn't contain side-effects.
With this commit `libp2p-autonat` no longer discards the whole remote payload in case an addr is unparsable, but instead logs the failure and skips the unparsable multiaddr.
See libp2p#3244 for details.
Instead of offering a public constructor, users are now no longer able to construct `ConnectionId`s at all. They only public API exposed are the derived traits. Internally, `ConnectionId`s are monotonically incremented using a static atomic counter, thus no two connections will ever get assigned the same ID.
The trick with this one is to use `futures::Either` everywhere where we may wrap something that implements any of the `futures` traits. This includes the output of `EitherFuture` itself. We also need to implement `StreamMuxer` on `future::Either` because `StreamMuxer`s may be the the `Output` of `InboundUpgrade`.
It doesn't appear that https://github.com/rust-lang/rust-clippy/issues/10061 is going to be fixed any time soon. In the meantime, our CI is "red" which is misleading because we purposely don't require this CI check. It will however hit stable in ~ 2 weeks at which point our required clippy CI check will fail.
Suppress clippy lint with an `allow` to make it pass.
With this commit `libp2p-dcutr` no longer discards the whole remote payload in case an addr is unparsable, but instead logs the failure and skips the unparsable multiaddr.
See https://github.com/libp2p/rust-libp2p/issues/3244 for details.
Trait bounds on struct declarations should be avoided as much as possible because they creep into every reference of the type. To supply default type parameters, we don't need the trait bounds.
With this commit `libp2p-kad` no longer discards the whole peer payload in case an addr is invalid, but instead logs the failure, skips the invalid multiaddr and parses the remaining payload.
See https://github.com/libp2p/rust-libp2p/issues/3244 for details.

With this commit `libp2p-identify` no longer discards the whole identify payload in case a listen addr of the remote node is invalid, but instead logs the failure, skips the invalid multiaddr and parses the remaining identify payload.
This is especially relevant when rolling out a new protocol to a live network. Say that most nodes of a network run on an implementation version v1. Say that the `multiaddr` implementation is not aware of the `webrtc/` protocol. Say that a new version (v2) is rolled out to the network with support for the `webrtc/` protocol, listening via `webrtc/` by default. In such case all v1 nodes would discard all identify payloads of v2 nodes, given that the v2 identify payloads would contain the `webrtc/` protocol in their `listen_addr` addresses.
See https://github.com/libp2p/rust-libp2p/issues/3244 for details.
Remove the `derive_builder` dev-dependency in gossipsub. We can manually implement the builder functionality on top of the `Default` instance of `InjectNodes`.
Resolved#3228.
Previously, we applied a lifetime onto the entire `RecordStore` to workaround Rust not having GATs. With Rust 1.65.0 we now have GATs so we can remove this workaround.
Related https://github.com/libp2p/rust-libp2p/issues/3240. Without this change, we would have to specify HRTB in various places.
Currently, we store messages to be sent to the `ConnectionHandler` in an `Arc`. However, we never actually clone these messages as we can see with this patch, hence we remove this wrapping.

There is nothing wrong about being near the edge of the concurrency Kademlia allows. If there was an older stream about to be reused, it doesn't mean there was anything wrong to warn about.
This patch addresses #2500 for the `libp2p-floodsub` crate.
For this PR the existing code was upgraded to use `Framed` with the `prost_codec::Codec` as the standard codec for handling the RPC message format serialization/deserialization.
Previously, we used to buffer events separately and emit actions directly. That is unnecessary. We can have a single place where we return from the `poll` loop and shove all actions into the same buffer.
As I do frequently, I corrected for the latest clippy warnings. This will make sure the CI won't complain in the future. We could automate this btw and maybe run the nightly version of clippy.
This patch deprecates 3 out of 4 functions on `PollParameters`:
- `local_peer_id`
- `listened_addresses`
- `external_addresses`
The addresses can be obtained by inspecting the `FromSwarm` event. To make this easier, we introduce two utility structs in `libp2p-swarm`:
- `ExternalAddresses`
- `ListenAddresses`
A node's `PeerId` is always known to the caller, thus we can require them to pass it in.
Related: #3124.
`cargo semver-checks` is still missing features in regards to properly detecting renamed exports. To make our CI pass again, we remove the renamed export, replace it with type-aliases and deprecate them to point users types exported under a module which now follows the conventions set in #2217.
