rishflab dd07e2f882 Add Alice execution path 
Consolidate and simplify swap execution. Generators are no longer
needed. Consolidate recovery and swap data structures. The
recursive calls can be replaced with a loop if returning prior to
completion is desired for testing purposes.

Fill out alice abort path

Move state machine executors into seperate files

Not compiling due to recursion/async issues

Fix async recursion compilation errors

Fix Bob swap execution

Remove check for ack message from Alice. Seems like a bad idea to
rely on an acknowledgement message instead of looking at the
blockchain.

Fix Bob abort

Fix warnings

Xmr lock complete

Add TxCancel submit to XmrLocked

Bob swap completed

Remove alice

Lucas Soriano del Pino 483c819e17 Correctly re-export types from bitcoin and monero modules 4 years ago
Lucas Soriano del Pino 28225f8643 Implement swap recover function for Alice 
This introduces a lot of duplication between the binary and the
library, but it's okay because this module should only be a temporary
measure until we allow recovery to be handled by the original state
machine.

Also, fix a bug in `xmr_btc::alice::action_generator` caused by the
incorrect assumption that Alice's ability to punish Bob could be
determined before the cancel transaction hits the blockchain.

rishflab ea08778b2f Save state for Bob at specific points in the swap 4 years ago
Lucas Soriano del Pino 4790d701e5 Update cross-curve-dleq dependency 
Making build times considerably faster.

On my machine, after running `cargo clean`, `cargo build -p swap`
takes 2min 19s.

The updated dependency also comes with a critical fix to the `Scalar`
type, which originally wrongly assumed that secp256k1 and ed25519
scalars had the same endianness. For this reason, we now have to
reverse the bytes of recovered scalars if we are to use them on a
different chain.

Finally, there is no need to append `RUST_MIN_STACK=100000000` to
avoid stack overflows in tests and when running the binary.

Tobin C. Harding 4d4acde476 Bubble up an event when Bob receives message 3 response 
Before this patch Bob is not sending message 3. This is because we are not
polling Bob's swarm correctly. To fix it we can just mimic the other NB's and
bubble up an event when Bob receives message 3 response from Alice, this way we
can `await` upon this event which triggers polling, making Bob's swarm send the
message.

Merge pull request #23 from comit-network/remove-re-export 
Do not re-export curve25519_dalek
 4 years ago
Tobin C. Harding cbccc282ef Send Message2 from Bob to Alice 
In order for Alice to complete the handshake she needs to transition to state 3,
for this she needs message 2 from Bob.

Send `bob::Message2` to Alice and transition to `State3` - completing the
handshake.

Lucas Soriano del Pino 0dd01c3a3b Do not re-export curve25519_dalek 
Anything that needs to be re-exported by this crate from
`curve25519_dalek` can be re-exported from the `monero` module. In
fact, the `Scalar` type was already being re-exported.

Lucas Soriano del Pino aa2a20916e Include Bob being inactive as a reason for failure 4 years ago
Lucas Soriano del Pino 41e8c7283c Verify Bob's redeem encsig as Alice 
Not doing so means that receiving an invalid encrypted signature from
Bob would make the generator produce a `RedeemBtc` action that should
not be accepted by the node (since Bob's signature would be invalid
after decrypting his encrypted signature).

It's better to fail early and let the user know what went wrong,
rather than let them hit an incomprehensible error when using their
wallet.

Lucas Soriano del Pino c86a82b315 Rename action_generator_alice to action_generator 4 years ago
Lucas Soriano del Pino e84c56378c Test that both parties refund if Alice does not redeem 
Also:

- Move generator functions to `alice` and `bob` modules. This makes
using `tracing` a lot easier, since the context of the file name let's
us differentiate between Alice's and Bob's generator logs more
clearly.
- Accept 0 confirmations when watching for the Monero lock
transaction. This should eventually be configured by the application,
but in the tests it's making things unexpectedly slower.
