Return `None` in in `<GenTcpTransport as Transport>::address_translation` if the
address is not a tcp address. Relevant if in case of something like
`OrTransport<TcpTransport, QuicTransport>`, where tcp would currently perform
the address translation for quic addresses.
Remove default features. You need to enable required features
explicitly now. As a quick workaround, you may want to use the
new `full` feature which activates all features.
We support two versions of the Noise XX handshake with X25519, but only one of
them is compliant with the specification and thus compliant with other
implementations. We should always default to the spec compliant handshake.
Fixes bug introduced in https://github.com/libp2p/rust-libp2p/pull/2887/
With if-watch `2.0.0` `IfWatcher::new` is not async anymore, hence the
`IfWatch` wrapping logic is obsolete.

Instead of having a mix of `poll_event`, `poll_outbound` and `poll_close`, we
flatten the entire interface of `StreamMuxer` into 4 individual functions:
- `poll_inbound`
- `poll_outbound`
- `poll_address_change`
- `poll_close`
This design is closer to the design of other async traits like `AsyncRead` and
`AsyncWrite`. It also allows us to delete the `StreamMuxerEvent`.
Remove the concept of individual `Transport::Listener` streams from `Transport`.
Instead the `Transport` is polled directly via `Transport::poll`. The
`Transport` is now responsible for driving its listeners.
See e04e95a for the rational.
With tokio `v1.19.0` released, `TcStream` exposes `take_error`.
This commit applies the same fix from e04e95a to the tokio TCP provider.
`libp2p` 0.45.1 depends (amongst others) on `libp2p-uds` v0.32.0 and on
`libp2p-core` v0.33.0 `libp2p-uds` v0.32.0, however, depends on `libp2p-core`
v0.32.0.
This commit changes the version mismatch for the upcoming `libp2p release.
* Remove unused import in rendezvous tests
* Expand uds-transport conditionals to include features
In case neither the tokio nor the async-std feature is defined,
this file needs to be empty to avoid unused code warnings.

This commit removes the `Clone` implementation on `GenTcpConfig` and consequently the `Clone`
implementations on `GenDnsConfig` and `WsConfig`.
When port-reuse is enabled, `GenTcpConfig` tracks the addresses it is listening in a `HashSet`. This
`HashSet` is shared with the `TcpListenStream`s via an `Arc<Mutex<_>>`. Given that `Clone` is
`derive`d on `GenTcpConfig`, cloning a `GenTcpConfig`, results in both instances sharing the same
set of listen addresses. This is not intuitive.
This behavior is for example error prone in the scenario where one wants to speak both plain DNS/TCP and
Websockets. Say a user creates the transport in the following way:
``` Rust
let transport = {
let tcp = tcp::TcpConfig::new().nodelay(true).port_reuse(true);
let dns_tcp = dns::DnsConfig::system(tcp).await?;
let ws_dns_tcp = websocket::WsConfig::new(dns_tcp.clone());
dns_tcp.or_transport(ws_dns_tcp)
};
```
Both `dns_tcp` and `ws_dns_tcp` share the set of listen addresses, given the `dns_tcp.clone()` to
create the `ws_dns_tcp`. Thus, with port-reuse, a Websocket dial might reuse a DNS/TCP listening
port instead of a Websocket listening port.
With this commit a user is forced to do the below, preventing the above error:
``` Rust
let transport = {
let dns_tcp = dns::DnsConfig::system(tcp::TcpConfig::new().nodelay(true).port_reuse(true)).await?;
let ws_dns_tcp = websocket::WsConfig::new(
dns::DnsConfig::system(tcp::TcpConfig::new().nodelay(true).port_reuse(true)).await?,
);
dns_tcp.or_transport(ws_dns_tcp)
};
```

Previously `libp2p-swarm` required a `Transport` to be `Clone`. Methods
on `Transport`, e.g. `Transport::dial` would take ownership, requiring
e.g. a `Clone::clone` before calling `Transport::dial`.
The requirement of `Transport` to be `Clone` is no longer needed in
`libp2p-swarm`. E.g. concurrent dialing can be done without a clone per
dial.
This commit removes the requirement of `Clone` for `Transport` in
`libp2p-swarm`. As a follow-up methods on `Transport` no longer take
ownership, but instead a mutable reference (`&mut self`).
On the one hand this simplifies `libp2p-swarm`, on the other it
simplifies implementations of `Transport`.

This commit removes the `Network` abstraction, thus managing `Listeners`
and the connection `Pool` in `Swarm` directly. This is done under the
assumption that noone uses the `Network` abstraction directly, but
instead everyone always uses it through `Swarm`. Both `Listeners` and
`Pool` are moved from `libp2p-core` into `libp2p-swarm`. Given that they
are no longer exposed via `Network`, they can be treated as an
implementation detail of `libp2p-swarm` and `Swarm`.
This change does not include any behavioural changes.
This change has the followin benefits:
- Removal of `NetworkEvent`, which was mostly an isomorphism of
`SwarmEvent`.
- Removal of the never-directly-used `Network` abstraction.
- Removal of now obsolete verbose `Peer` (`core/src/network/peer.rs`)
construct.
- Removal of `libp2p-core` `DialOpts`, which is a direct mapping of
`libp2p-swarm` `DialOpts`.
- Allowing breaking changes to the connection handling and `Swarm` API
interface without a breaking change in `libp2p-core` and thus a
without a breaking change in `/transport` protocols.
This change enables the following potential future changes:
- Removal of `NodeHandler` and `ConnectionHandler`. Thus allowing to
rename `ProtocolsHandler` into `ConnectionHandler`.
- Moving `NetworkBehaviour` and `ProtocolsHandler` into `libp2p-core`,
having `libp2p-xxx` protocol crates only depend on `libp2p-core` and
thus allowing general breaking changes to `Swarm` without breaking all
`libp2p-xxx` crates.
