Daniel Karzel	c0070f8fa7	Move files from `protocol` to appropriate module ... Some network and application specific code does not belong in the protocol module and was moved. Eventloop, recovery and the outside behaviour were moved to the respective application module because they are application specific. The `swap_setup` was moved into the network module because upon change both sides will have to be changed and should thus stay close together.	3 years ago
Daniel Karzel	818147a629	`swap_setup` instead of `spot_price` and `execution_setup` ... Having `spot_price` and `execution_setup` as separate protocols did not bring any advantages, but was problematic because we had to ensure that `execution_setup` would be triggered after `spot_price`. Because of this dependency it is better to combine the protocols into one. Combining the protocols also allows a refactoring to get rid of the `libp2p-async-await` dependency. Alice always listens for the `swap_setup` protocol. When Bob opens a substream on that protocol the spot price is communicated, and then all execution setup messages (swap-id and signature exchange).	3 years ago
Daniel Karzel	89b3d07eba	Network protocol tests for spot_price behaviour ... Each test spawns swarm for Alice and Bob that only contains the spot_price behaviours and uses a memory transport. Tests cover happy path (i.e. expected price is returned) and error scenarios. Implementation of `TestRate` on `LatestRate` allows testing rate fetch error and quote calculation error behaviour. Thanks to @thomaseizinger for ramping up the test framework for comit-rs in the past!	3 years ago
Philipp Hoenisch	632293cf91	Add support for swapping through Tor. ... This PR does a few things. * It adds a TorTransport which either dials through Tor's socks5 proxy or via clearnet. * It enables ASB to register hidden services for each network it is listening on. We assume that we only care about different ports and re-use the same onion-address for all of them. The ASB requires to have access to Tor's control port. * It adds support to dial through a local Tor socks5 proxy. We assume that Tor is always available on localhost. Swap cli only requires Tor to be running so that it can send messages via Tor's socks5 proxy. * It adds a new e2e test which swaps through Tor. For this we assume that Tor is currently running on localhost. All other tests are running via clear net.	3 years ago
Daniel Karzel	c1e993deb2	Json codec for quote protocol ... A `RequestResponseCodec` for pull-based protocols where the response is encoded using JSON. This was added to more properly express the behavior of the quote protocol, where the dialer doesn't send any message and expects the listener to directly send the response.

Thomas Eizinger	b417950f99	Improve error reporting of failed protocols ... Instead of forwarding every error, we deliberately ignore certain variants that are not worth being printed to the log. In particular, this concerns "UnsupportedProtocols" and "ResponseOmission". To make this less verbose we introduce a macro for mapping a `RequestResponseEvent` to `{alice,bob}::OutEvent`. We use a macro because those `OutEvent`s are different types and the only other way of abstracting over them would be to introduce traits that we implement on both of them. To make the macro easier to use, we move all the `From` implementations that convert between the protocol and the more high-level behaviour into the actual protocol module.	3 years ago
Thomas Eizinger	f0f7288bb6	Introduce a `redial::Behaviour` ... This behaviour makes Bob re-dial Alice with an exponential backoff as soon as the connection is lost.	3 years ago
Thomas Eizinger	cde3f0f74a	Remove connection handling from swap execution ... The swap should not be concerned with connection handling. This is the responsibility of the overall application. All but the execution-setup NetworkBehaviour are `request-response` behaviours. These have built-in functionality to automatically emit a dial attempt in case we are not connected at the time we want to send a message. We remove all of the manual dialling code from the swap in favor of this behaviour. Additionally, we make sure to establish a connection as soon as the EventLoop gets started. In case we ever loose the connection to Alice, we try to re-establish it.	3 years ago
Thomas Eizinger	2200fce3f3	Pass Swarm into EventLoop ... This reduces the amount of arguments we need to pass into the eventloop at the expense of slightly more setup of the swarm.	3 years ago
Thomas Eizinger	0c0a322a8f	Rename module to better represent what it contains ... This module provides an implementation of the RequestResponseCodec using a cbor serialization.	3 years ago
Thomas Eizinger	1de0b39b32	Unify encrypted-signature protocol to a single one	3 years ago
Thomas Eizinger	9979cc9f1f	Unify transfer-proof protocol to a single one ... Previously, we had two implementations of this protocol. To reduce code size, we make Alice and Bob use the same implementation.	3 years ago
Thomas Eizinger	601bf07255	Introduce `quote` protocol and display it to the user before they fund ... Previously, the user neither knew the price nor the maximum quantity they could trade. We now request a quote from the user and display it to them. Fixes #255.	3 years ago

Thomas Eizinger	7042ed9441	Replace quote with spot-price protocol ... This is essentially functionally equivalent but includes some cleanups by removing a layer of abstraction: `spot_price::Behaviour` is now just a type-alias for a request-response behaviour.	3 years ago
Thomas Eizinger	a4c25080b6	Merge network::Seed into crate::Seed ... This allows us to unify the way we derive new secret key material and simplify the usage of seed by only having a single one.	3 years ago

Daniel Karzel	664958939d	Create network::Seed from swap::Seed instead of abstracting over byte array	3 years ago
Daniel Karzel	0a21040e08	Deterministic peer id from seed for alice ... This includes the introduction of the --data-dir parameter instead of the --database. Both the seed file and the database are stored in the data-dir, the database in sub-folder `database`.	3 years ago
Franck Royer	cdf2800fa5	Align clippy lints ... Lints in `main.rs` are not used if there is a `lib.rs` file.	3 years ago
Tobin C. Harding	05766d3146	Add swap/ ... Add a binary crate `swap` that implements two nodes (Alice and Bob). With this applied we can start up a node for each role and do: - Bob: Requests current amounts using BTC is input - Alice: Responds with amounts - Bob: (mock) get user input to Ok the amounts ... continue with swap (TODO)	4 years ago
