CLI log statements to be more JSON friendly
Values to be logged as fields.

Introduce --json flag for the CLI
When `--json` is used the CLI does not log to file, but only on the command line in json output.

CLI --help and --version are handled correctly
Since we introduced our own parsing function for command line arguments, we have to make sure that clap's behaviour is handled correctly.
Clap's `get_matches_from_safe` returns an error of a certain kind, of which `ErrorKind::HelpDisplayed` and `ErrorKind::VersionDisplayed ` have to be handled to properly print the help/version and exit the program.
The clap error includes the message, so we print help/version in main now and ensure the program exits with `0` afterwards.

Simplify ASB initial setup signature 2021-05-20 13:05:51 +10:00

ASB config may specify finality confirmations
By default the finality confirmations of the network's `env::Config` will be applied and no finality confirmations will be persisted on disk in the config file.
It is however possible to set finality confirmations in the config file for bitcoin and monero for power users at their own risk.
If set the defaults will be overwritten with the parameter from the config file upon startup.

Activate mainnet for the ASB
To run the ASB on testnet, one actively has to provide the `--testnet` flag.
Mainnet and testnet data and config are separated into sub-folders, i.e. `{data/config-dir}/asb/testnet` and `{data-dir}/asb/mainnet`.
The initial setup is also per network. If (default) config for the network cannot be found the initial setup is triggered.
Startup includes network check to ensure the bitcoin/monero network in config file is the same as the one in the `env::Config`.

Note: Wallet initialization is done with the network set in the `env::Config`, the network saved in the config file is just to indicate what network the config file is for.

Activate mainnet for the CLI
This includes testing CLI commandline args
Clap's `default_value_with` actually did not work on `Subcommand`s because the parent's flags were not picked up.
This was fixed by changing parameters dependent on testnet/mainnet to options.
This problem should have been detected by tests, that's why the command line parameter tests were finally (re-)added.

Thanks to @rishflab for some pre-work for this.

Remove duplication and cleanup
In the past we had problems with flags/parameter changes several times, where on instance was changed, buy another one was missed. This should mitigate this problem.
This patch introduces structs for all duplicated parameters and uses flatten to only have one point for changes.

Additionally removes all mentions of `alice` from the commands / variables. This code is on an application level and should not be concerned with swap protocol roles.

Introduce a minimum buy amount
Introduces a minimum buy Bitcoin amount similar to the maximum amount already present.

Move max_buy and ask_spread into config
Max-buy and spread is not something that one would configure on every run.
More convenient to keep this in the config.

The max-buy Bitcoin value was adapted to `0.02` which is more reasonable for mainnet.
Activated feature `serde-float` to serialize the spread (Decimal) as float instead of string.

```
...

[maker]
max_buy_btc = 0.02
ask_spread = 0.02

Move loading the state into the function
In the production code it is a weird indirection that we load the state and then pass in the state and the database.
In the tests we have one additional load by doing it inside the command, but loading from the db is not expensive.

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`).

Add resume-only mode for the ASB
Resume-only is a maintenance mode where no swaps are accepted but unfinished swaps are resumed.
This is achieve by ignoring incoming spot-price requests (that would lead to execution setup) in the event-loop.

Add config/argument to swap/asb to configure bitcoin tx fees. 2021-05-07 10:24:41 +10:00
Philipp Hoenisch
ee90c228b4
Dynamically calculate fees using electrum's estimate_fee.
Electrum has an estimate-fee feature which takes as input the block you want a tx to be included.
The result is a recommendation of BTC/vbyte.
Using this recommendation and the knowledge about the size of our transactions we compute an appropriate fee.
The size of the transactions were taken from real transactions as published on bitcoin testnet.
Note: in reality these sizes might fluctuate a bit but not for much.

Different default directories for CLI and ASB
Using the same default directory as data-/config-dir has caused unwanted side effects when running both applications on the same machine.
Use these directory names:
- ASB: xmr-btc-swap-asb
- CLI: xmr-btc-swap-cli

Since the functionality is now application specific the respective functions were moved into the appropriate module of the application.

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.

405: Concurrent swaps with same peer r=da-kami a=da-kami

Fixes #367 

- [x] Concurrent swaps with same peer

Not sure how much more time I should invest into this. We could just merge the current state and then do improvements on top...?

Improvements:

- [x] Think `// TODO: Remove unnecessary swap-id check` through and remove it
- [x] Add concurrent swap test, multiple swaps with same Bob
- [ ] Save swap messages without matching swap in execution in the database
- [ ] Assert the balances in the new concurrent swap tests
- [ ] ~~Add concurrent swap test, multiple swaps with different Bobs~~
- [ ] ~~Send swap-id in separate message, not on top of `Message0`~~

Multiple swaps with the same peer
- Swap-id is exchanged during execution setup. CLI (Bob) sends the swap-id to be used in his first message.
- Transfer poof and encryption signature messages include the swap-id so it can be properly associated with the correct swap.
- ASB: Encryption signatures are associated with swaps by swap-id, not peer-id.
- ASB: Transfer proofs are still associated to peer-ids (because they have to be sent to the respective peer), but the ASB can buffer multiple
- CLI: Incoming transfer proofs are checked for matching swap-id. If a transfer proof with a different swap-id than the current executing swap is received it will be ignored. We can change this to saving into the database.

Includes concurrent swap tests with the same Bob.

- One test that pauses and starts an additional swap after the transfer proof was received. Results in both swaps being redeemed after resuming the first swap.
- One test that pauses and starts an additional swap before the transfer proof is sent (just after BTC locked). Results in the second swap redeeming and the first swap being refunded (because the transfer proof on Bob's side is lost). Once we store transfer proofs that we receive during executing a different swap into the database both swaps should redeem.

Note that the monero harness was adapted to allow creating wallets with multiple outputs, which is needed for Alice.

9745d150e7 Log at debug level to file
EnvFilter is applied globally. This means you cannot log at INFO level
to the terminal and at DEBUG level to log files. To get a around this
limitation I had to implement the layer trait on a new type and filter
in the on_event() trait method. Each swap has its own log file denoted
by its swap_id. The logger appends to the existing file when resuming a
swap.

Closes #278
