- Removes the `Swarm` type alias, renaming `ExpandedSwarm` to `Swarm`.
- Remove `TInEvent`, `TOutEvent` and `THandler` trait parameters on
`Swarm`, instead deriving them through `TBehaviour`. Move derive logic
to separate type aliases.
- Simplify trait bounds on `Swarm` main `impl` and `Stream` `impl`.
With 45f07bf8639fd9056e4ffe52298ca113a0308951 `Network::dial` accepts a
`Multiaddr` with a `PeerId`. With that in mind the doc comment on
`NetworkBehaviourAction::DialAddress` is outdated.
Don't close connection if ping protocol is unsupported by remote. Previously, a
failed protocol negotation for ping caused a force close of the connection. As a
result, all nodes in a network had to support ping. To allow networks where some
nodes don't support ping, we now emit `PingFailure::Unsupported` once for every
connection on which ping is not supported.

Not all implementations of `NetworkBehaviour` need all callbacks.
We've have been adding new callbacks with default implementations
for a while now. There is no reason the initial ones cannot also
be defaulted, thus making it easier create new implementations.

- Change `PublicKey::into_protobuf_encoding` to
`PublicKey::to_protobuf_encoding`.
- Change `PublicKey::into_peer_id` to `PublicKey::to_peer_id`.
- Change `PeerId::from_public_key(PublicKey)` to
`PeerId::from_public_key(&PublicKey)`.
- Add `From<&PublicKey> for PeerId`.

Add `ExpandedSwarm::disconnect_peer_id` and
`NetworkBehaviourAction::CloseConnection` to close connections to a specific
peer via an `ExpandedSwarm` or `NetworkBehaviour`.

Change `Stream` implementation of `ExpandedSwarm` to return all
`SwarmEvents` instead of only the `NetworkBehaviour`'s events.
Remove `ExpandedSwarm::next_event`. Users can use `<ExpandedSwarm as
StreamExt>::next` instead.
Remove `ExpandedSwarm::next`. Users can use `<ExpandedSwarm as
StreamExt>::filter_map` instead.
Remove `Deref` and `DerefMut` implementations previously dereferencing
to the `NetworkBehaviour` on `Swarm`. Instead one can access the
`NetworkBehaviour` via `Swarm::behaviour` and `Swarm::behaviour_mut`.
Methods on `Swarm` can now be accessed directly, e.g. via
`my_swarm.local_peer_id()`.
Reasoning: Accessing the `NetworkBehaviour` of a `Swarm` through `Deref`
and `DerefMut` instead of a method call is an unnecessary complication,
especially for newcomers. In addition, `Swarm` is not a smart-pointer
and should thus not make use of `Deref` and `DerefMut`, see documentation
from the standard library below.
> Deref should only be implemented for smart pointers to avoid
confusion.

* Implement `/dnsaddr` support on `libp2p-dns`.
To that end, since resolving `/dnsaddr` addresses needs
"fully qualified" multiaddresses when dialing, i.e. those
that end with the `/p2p/...` protocol, we make sure that
dialing always uses such fully qualified addresses by
appending the `/p2p` protocol as necessary. As a side-effect,
this adds support for dialing peers via "fully qualified"
addresses, as an alternative to using a `PeerId` together
with a `Multiaddr` with or without the `/p2p` protocol.
* Adapt libp2p-relay.
* Update versions, changelogs and small cleanups.
* Remove substream-specific protocol negotiation version.
Remove the option for a substream-specific multistream select protocol override.
The override at this granularity is no longer deemed useful, in particular because
it can usually not be configured for existing protocols like `libp2p-kad` and others.
There is a `Swarm`-scoped configuration for this version available since
[1858](https://github.com/libp2p/rust-libp2p/pull/1858).
* Update protocol crate versions and changelogs.
* Clean up documentation.
* Make clippy "happy".
Address all clippy complaints that are not purely stylistic (or even
have corner cases with false positives). Ignore all "style" and "pedantic" lints.
* Fix tests.
* Undo unnecessary API change.
`NetworkBehaviour::inject_connected` is called for the first established
connection to a peer only. See `swarm/src/lib.rs`:
```rust
this.behaviour.inject_connection_established(&peer_id, &connection.id(), &endpoint);
if num_established.get() == 1 {
this.behaviour.inject_connected(&peer_id);
}
```
This commit adjusts the documentation accordingly.
* swarm/src/toggle: Ignore listen upgr errors when disabled
A disabled `ToggleProtoHandler` can receive listen upgrade errors in the
following two cases:
1. Protocol negotiation on an incoming stream failed with no protocol being
agreed on.
2. When combining `ProtocolsHandler` implementations a single `ProtocolsHandler`
might be notified of an inbound upgrade error unrelated to its own upgrade
logic. For example when nesting a `ToggleProtoHandler` in a
`ProtocolsHandlerSelect` the former might receive an inbound upgrade error
even when disabled.
`ToggleProtoHandler` should ignore the error in both of these cases.
* *: Prepare libp2p-swarm v0.27.2 release
Move transport upgrade protocols from `protocols/`
to `transports/`, such that only "application protocols"
that depend on `libp2p-swarm` remain in `protocols/`,
whereas there is no such dependency in `transports/`
outside of integration tests.
Tweak README and top-level CHANGELOG.
* Allow OneShotHandler's `max_dial_negotiate` limit to be configurable.
* Update version and CHANGELOG.,

`futures-codec` has not been updated in the recent months. It still
depends on `bytes` `v0.5` preventing all downstream dependencies to
upgrade to `bytes` `v1.0`.
This commit replaces `futures_codec` in favor of `asynchronous-codec`
The latter is a fully upgraded fork of the former.
In addition this commit upgrades:
- bytes to v1
- unsigned-varint to v0.6.0
- prost to v0.7
Remove `NotifyHandler::All` thus removing the requirement for events
send from a `NetworkBehaviour` to a `ProtocolsHandler` to be `Clone`. An
implementor of `NetworkBehaviour` can still notify all
`ProtocolHandler`s for a given peer by emitting one `NotifyHandler`
event per connection to that peer.
Commit 335e55e6 removed the `ConnectionInfo` trait in favor of
`PeerId`s. Commit 1bd013c8 removed `ExpandedSwarm::connection_info` as
it would only return the `PeerId` that the caller is already aware of.
One could use `ExpandedSwarm::connection_info` not only to retrieve the
`ConnectionInfo` for a given peer, but also to check whether the
underlying `Network` has a connection to the peer.
This commit exposes the `is_connected` method on `Network` via
`ExpandedSwarm` to check whether the `Network` has an established
connection to a given peer.
* Refactor and extend configurable connection limits.
To better track different connection counts, permit configurable
limits for these counts and make these available for
inspection efficiently, introduce dedicated connection counters
via a `ConnectionCounters` structure that is exposed on the
API via the `NetworkInfo`. All connection or connection
states that are counted in this way can also have effective
configurable limits.
* Cleanup
* Add missing file.
* Refine naming and config API.
* Update core/CHANGELOG.md

addresses to be retained "forever" or until explicitly removed.

* feat: upgrade to multihash 0.13
`multihash` changes a lot internally, it is using stack allocation instead
of heap allocation. This leads to a few limitations in regards on how
`Multihash` can be used.
Therefore `PeerId` is now using a `Bytes` internally so that only minimal
changes are needed.
* Update versions and changelogs.

In all cases, we pass the PeerId directly as the connection info.
The flexbility of doing something different here was originally
envisioned but turned out to be never needed.

> Futures managed by FuturesUnordered will only be polled when they
generate wake-up notifications. This reduces the required amount of work
needed to poll large numbers of futures.
https://docs.rs/futures/0.3.5/futures/stream/struct.FuturesUnordered.html
Instead of iterating each inbound and outbound upgrade looking for one
to make progress, use a `FuturesUnordered` for both pending inbound and
pending outbound upgrades. As a result only those upgrades are polled
that are ready to progress.
* [multistream-select] Fix panic with V1Lazy and add integration tests.
Fixes a panic when using the `V1Lazy` negotiation protocol,
a regression introduced in https://github.com/libp2p/rust-libp2p/pull/1484.
Thereby adds integration tests for a transport upgrade with both
`V1` and `V1Lazy` to the `multistream-select` crate to prevent
future regressions.
* Cleanup.
* Update changelog.
* Simplify incoming connection handling.
Instead of handing out a mutable borrow to the connection
pool in the `IncomingConnectionEvent`, so one can call
`IncomingConnectionEvent::accept()`, just provide
`Network::accept()`.
* Update docs.
* Update CHANGELOG.
