* Addressing #473 ... if I understood the ticket right, we want to pass through whatever the application provides as a topic identifier, leaving hashing (or not hashing) up to the application.
* Remove TopicDescriptor and use Topic newtype everywhere
* PR feedback
Use From<Topic> instead of Into<String>
Use impl Into<Topic> instead of Topic in public API

* 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.
Update the protocols and transport subdirectories to the 2018 edition.
NB: The websocket transport cannot be moved to 2018 edition due to
websocket-rs's use of the keyword async as the name of a module.
* Move lib.rs to protocol.rs
* Rewrite floodsub for ProtocolsHandler
* Add a FloodsubBehaviour
* Fix closing floodsub after a message
* Address concern
* Make it conform to the protocol
* Make it really conformant
* Address concerns
