* Implement Debug for (ed25519|secp256k1)::(Keypair|SecretKey) (#1285)
* Fix possible arithmetic overflow in libp2p-kad. (#1291)
When the number of active queries exceeds the (internal)
JOBS_MAX_QUERIES limit, which is only supposed to bound
the number of concurrent queries relating to background
jobs, an arithmetic overflow occurs. This is fixed by
using saturating subtraction.

This actually builds 😊.
* Bump all dependencies
Includes the excellent work of @rschulman in #1265.
* Remove use of ed25519-dalek fork

* Add compatibility hack for rand
Cargo allows a crate to depend on multiple versions of another, but
`cargo-web` panics in that situation. Use a wrapper crate to work
around the panic.

instead of my own ugly hack.

* Remove unwraps and `#[allow(deprecated)]`.
* Remove spurious changes to dependencies
Bumping minor or patch versions is not needed, and increases likelyhood
of merge conflicts.

`ed25519::SecretKey::from_bytes` will never fail for 32-byte inputs.
* Revert changes that don’t belong in this PR
* Remove using void to bypass ICE (#1295)
* Publish 0.13.0 (#1294)
* *: Remove usage of custom buffer initialization usage
With version `0.3.0-alpha.19` the futures-preview crate makes the
`AsyncRead::initializer` API unstable.
In order to improve interoperability with e.g. both a library depending
on alpha.18 as well as a library depending on alpha.19 and in order for
rust-libp2p to become stable again, this commit removes all usages of
the unstable `initializer` API.
* protocols/noise: Remove NoiseOutput Asyncread initializer
* transports/tcp: Remove TcpTransStream AsyncRead initializer
* *: Remove version pinning of futures-preview to 0.3.0-alpha.18
With version 0.3.0-alpha.19 the futures-preview crate makes the
AsyncRead::initializer API unstable. Given that the previous commits
removed usage of the initializer API, the version pinning is not needed
any longer.
* Configurable multistream-select protocol. Add V1Lazy variant. (#1245)
Make the multistream-select protocol (version) configurable
on transport upgrades as well as for individual substreams.
Add a "lazy" variant of multistream-select 1.0 that delays
sending of negotiation protocol frames as much as possible
but is only safe to use under additional assumptions that
go beyond what is required by the multistream-select v1
specification.

* Rework the transport upgrade API.
ALthough transport upgrades must follow a specific pattern
in order fot the resulting transport to be usable with a
`Network` or `Swarm`, that pattern is currently not well
reflected in the transport upgrade API. Rather, transport
upgrades are rather laborious and involve non-trivial code
duplication.
This commit introduces a `transport::upgrade::Builder` that is
obtained from `Transport::upgrade`. The `Builder` encodes the
previously implicit rules for transport upgrades:
1. Authentication upgrades must happen first.
2. Any number of upgrades may follow.
3. A multiplexer upgrade must happen last.
Since multiplexing is the last (regular) transport upgrade (because
that upgrade yields a `StreamMuxer` which is no longer a `AsyncRead`
/ `AsyncWrite` resource, which the upgrade process is based on),
the upgrade starts with `Transport::upgrade` and ends with
`Builder::multiplex`, which drops back down to the `Transport`,
providing a fluent API.
Authentication and multiplexer upgrades must furthermore adhere
to a minimal contract w.r.t their outputs:
1. An authentication upgrade is given an (async) I/O resource `C`
and must produce a pair `(I, D)` where `I: ConnectionInfo` and
`D` is a new (async) I/O resource `D`.
2. A multiplexer upgrade is given an (async) I/O resource `C`
and must produce a `M: StreamMuxer`.
To that end, two changes to the `secio` and `noise` protocols have been
made:
1. The `secio` upgrade now outputs a pair of `(PeerId, SecioOutput)`.
The former implements `ConnectionInfo` and the latter `AsyncRead` /
`AsyncWrite`, fulfilling the `Builder` contract.
2. A new `NoiseAuthenticated` upgrade has been added that wraps around
any noise upgrade (i.e. `NoiseConfig`) and has an output of
`(PeerId, NoiseOutput)`, i.e. it checks if the `RemoteIdentity` from
the handshake output is an `IdentityKey`, failing if that is not the
case. This is the standard upgrade procedure one wants for integrating
noise with libp2p-core/swarm.
* Cleanup
* Add a new integration test.
* Add missing license.
* Remove tokio-codec dependency from multistream-select.
In preparation for the eventual switch from tokio to std futures.
Includes some initial refactoring in preparation for further work
in the context of https://github.com/libp2p/rust-libp2p/issues/659.
* Reduce default buffer sizes.
* Allow more than one frame to be buffered for sending.
* Doc tweaks.
* Remove superfluous (duplicated) Message types.
* Reduce roundtrips in multistream-select negotiation.
1. Enable 0-RTT: If the dialer only supports a single protocol, it can send
protocol data (e.g. the actual application request) together with
the multistream-select header and protocol proposal. Similarly,
if the listener supports a proposed protocol, it can send protocol
data (e.g. the actual application response) together with the
multistream-select header and protocol confirmation.
2. In general, the dialer "settles on" an expected protocol as soon
as it runs out of alternatives. Furthermore, both dialer and listener
do not immediately flush the final protocol confirmation, allowing it
to be sent together with application protocol data. Attempts to read
from the negotiated I/O stream implicitly flushes any pending data.
3. A clean / graceful shutdown of an I/O stream always completes protocol
negotiation.
The publich API of multistream-select changed slightly, requiring both
AsyncRead and AsyncWrite bounds for async reading and writing due to
the implicit buffering and "lazy" negotiation. The error types have
also been changed, but they were not previously fully exported.
Includes some general refactoring with simplifications and some more tests,
e.g. there was an edge case relating to a possible ambiguity when parsing
multistream-select protocol messages.
* Further missing commentary.
* Remove unused test dependency.
* Adjust commentary.
* Cleanup NegotiatedComplete::poll()
* Fix deflate protocol tests.
* Stabilise network_simult test.
The test implicitly relied on "slow" connection establishment
in order to have a sufficient probability of passing.
With the removal of roundtrips in multistream-select, it is now
more likely that within the up to 50ms duration between swarm1
and swarm2 dialing, the connection is already established, causing
the expectation of step == 1 to fail when receiving a Connected event,
since the step may then still be 0.
This commit aims to avoid these spurious errors by detecting runs
during which a connection is established "too quickly", repeating
the test run.
It still seems theoretically possible that, if connections are always
established "too quickly", the test runs forever. However, given that
the delta between swarm1 and swarm2 dialing is 0-50ms and that the
TCP transport is used, that seems probabilistically unlikely.
Nevertheless, the purpose of the artificial dialing delay between
swarm1 and swarm2 should be re-evaluated and possibly at least
the maximum delay further reduced.
* Complete negotiation between upgrades in libp2p-core.
While multistream-select, as a standalone library and providing
an API at the granularity of a single negotiation, supports
lazy negotiation (and in particular 0-RTT negotiation), in the
context of libp2p-core where any number of negotiations are
composed generically within the concept of composable "upgrades",
it is necessary to wait for protocol negotiation between upgrades
to complete.
* Clarify docs. Simplify listener upgrades.
Since reading from a Negotiated I/O stream implicitly flushes any pending
negotiation data, there is no pitfall involved in not waiting for completion.
