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
Thomas Eizinger	8a30ef725c	Refactor transports to construct them specific for each application ... Instead of splitting up the transports into capabilities, we compose them directly for each application. This allows us to remove the websocket transport for the CLI which is really only needed for the ASB to allow retrieval of quotes via the browser.	3 years ago

Daniel Karzel	652aae9590	Introduce a minimum buy amount ... Introduces a minimum buy Bitcoin amount similar to the maximum amount already present. For the CLI the minimum amount is enforced by waiting until at least the minimum is available as max-giveable amount.	3 years ago
Daniel Karzel	5aac76598d	Decouple ASB/CLI Errors from Error sent over wire ... What goes over the wire should not be coupled to the errors being printed. For the CLI and ASB we introduce a separate error enum that is used for logging. When sending over the wire the errors are mapped to and from the `network::spot_price::Error`. As part of Bob-specific spot_price code was moved from the network into bob. Clearly separation of the network API from bob/alice.	3 years ago
Daniel Karzel	52f648e1de	Alice's spot price logic into dedicated behaviour ... Move Alice's spot price logic into a dedicated network behaviour that handles all the logic. The new behaviour encapsulates the complete state necessary for spot price request decision making. The network behaviour cannot handle asynchronous calls, thus the balance is managed inside the spot price and has to updated regularly from the outside to ensure the spot price balance check has up to date data. At the moment the balance is updated upon an incoming quote requests. Code that is relevant for both ASB and CLI remains in the `network::spot_price` module (e.g. `network::spot_price::Error`).	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	0f11ab051e	Print peer ID on debog when starting CLI ... In order to add more context to the debug logs we print Bob's peer ID. This allows identifying peer related logs on the ASB.	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	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
