This patch-set introduces `libp2p-swarm-test`. It provides utilities for quick and safe bootstrapping of tests for `NetworkBehaviour`s. The main design features are:
- Everything has timeouts
- APIs don't get in your way
- Minimal boilerplate
Closes#2884.
Pull-Request: #2888.
Instead of relying on `protoc` and buildscripts, we generate the bindings using `pb-rs` and version them within our codebase. This makes for a better IDE integration, a faster build and an easier use of `rust-libp2p` because we don't force the `protoc` dependency onto them.
Resolves#3024.
Pull-Request: #3312.
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.
With f2905c07f1246c3c3fdc1cde95f7e9c5c1c9b01a the secp256k1 feature is
disabled by default. Instead of enabling it in the dev-dependency,
simply use ed25519.
- 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`.

`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
This commit upgrades the current gossipsub implementation to support the [v1.1
spec](https://github.com/libp2p/specs/blob/master/pubsub/gossipsub/gossipsub-v1.1.md).
It adds a number of features, bug fixes and performance improvements.
Besides support for all new 1.1 features, other improvements that are of particular note:
- Improved duplicate LRU-time cache (this was previously a severe bottleneck for
large message throughput topics)
- Extended message validation configuration options
- Arbitrary topics (users can now implement their own hashing schemes)
- Improved message validation handling - Invalid messages are no longer dropped
but sent to the behaviour for application-level processing (including scoring)
- Support for floodsub, gossipsub v1 and gossipsub v2
- Protobuf encoding has been shifted into the behaviour. This has permitted two
improvements:
1. Message size verification during publishing (report to the user if the
message is too large before attempting to send).
2. Message fragmentation. If an RPC is too large it is fragmented into its
sub components and sent in smaller chunks.
Additional Notes
The peer eXchange protocol defined in the v1.1 spec is inactive in its current
form. The current implementation permits sending `PeerId` in `PRUNE` messages,
however a `PeerId` is not sufficient to form a new connection to a peer. A
`Signed Address Record` is required to safely transmit peer identity
information. Once these are confirmed (https://github.com/libp2p/specs/pull/217)
a future PR will implement these and make PX usable.

This adds optional message signing and verification to the gossipsub protocol as
per the libp2p specifications.
In addition this commit:
- Removes the LruCache received cache and simply uses the memcache in it's
place.
- Send subscriptions to all peers
- Prevent invalid messages from being gossiped
- Send grafts when subscriptions are added to the mesh
