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.

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.
Previously, we would erroneously always go into the `WaitingUser` (now called `WaitingBehaviour`) state after receiving a message on an inbound stream. However, the `AddProvider` message does not warrant a "response" from the behaviour. Thus, any incoming `AddProvider` message would result in a stale substream that would eventually be dropped as soon as more than 32 inbound streams have been opened.
With this patch, we inline the message handling into the upper match block and perform the correct state transition upon each message. For `AddProvider`, we go back into `WaitingMessage` because the spec mandates that we need to be ready to receive more messages on an inbound stream.
Fixes#3048.
We refactor our continuous integration workflow with the following goals in mind:
- Run as few jobs as possible
- Have the jobs finish as fast as possible
- Have the jobs redo as little work as possible
There are only so many jobs that GitHub Actions will run in parallel.
Thus, it makes sense to not create massive matrices but instead group
things together meaningfully.
The new `test` job will:
- Run once for each crate
- Ensure that the crate compiles on its specified MSRV
- Ensure that the tests pass
- Ensure that there are no semver violations
This is an improvement to before because we are running all of these
in parallel which speeds up execution and highlights more errors at
once. Previously, tests run later in the pipeline would not get run
at all until you make sure the "first" one passes.
We also previously did not verify the MSRV of each crate, making the
setting in the `Cargo.toml` rather pointless.
The new `cross` job supersedes the existing `wasm` job.
This is an improvement because we now also compile the crate for
windows and MacOS. Something that wasn't checked before.
We assume that checking MSRV and the tests under Linux is good enough.
Hence, this job only checks for compile-errors.
The new `feature_matrix` ensures we compile correctly with certain feature combinations.
`libp2p` exposes a fair few feature-flags. Some of the combinations
are worth checking independently. For the moment, this concerns only
the executor related transports together with the executor flags but
this list can easily be extended.
The new `clippy` job runs for `stable` and `beta` rust.
Clippy gets continuously extended with new lints. Up until now, we would only
learn about those as soon as a new version of Rust is released and CI would
run the new lints. This leads to unrelated failures in CI. Running clippy on with `beta`
Rust gives us a heads-up of 6 weeks before these lints land on stable.
Fixes#2951.
Previously, we had one callback for each kind of message that a `ConnectionHandler` would receive from either its `NetworkBehaviour` or the connection itself.
With this patch, we combine these functions, resulting in two callbacks:
- `on_behaviour_event`
- `on_connection_event`
Resolves#3080.
Currently, `libp2p-mdns` fails to compile unless we enable the `tokio` runtime feature flag. This is caused by missing `cfg` statements upstream. See https://github.com/bluejekyll/trust-dns/issues/1830.
Until this is fixed upstream, we temporarily enable the `tokio-runtime` feature of `trust-dns-proto`.
