Add workflow for creating new releases
Whenever a release branch - that is a branch starting with `release/` -
is merged into master, we create a new GitHub release based on the
version number in the branch name.

Similarly to the preview release, we extract the relevant section of
the changelog and make it the release body.

Add workflow for drafting a new release
Drafting a new release can be quite involved. One has to update the
changelog correctly, bump the versions in the manifest files, commit
everything and raise a PR.

This workflow does all of that for you at the click of a button!

Add CHANGELOG section to preview release
Whenever we create a preview release, we extract the `unreleased`
section of the CHANGELOG and make it the body of the Github release.

TODO:

- [x] Re-establish connection on Bob's side if it is dropped.
- [x] Make sure Alice buffers messages if there isn't currently a connection
- [x] Do a testnet swap to make sure it works

Re-order bob::event_loop based on importance 2021-03-24 15:17:54 +11:00
Thomas Eizinger
638a169a04
Buffer transfer proof if we are not connected to Bob
The request-response behaviour that is used for sending the transfer
proof actually has a functionality for buffering a message if we
are currently not connected. However, the request-response behaviour
also emits a dial attempt and **drops** all buffered messages if this
dial attempt fails. For us, the dial attempt will very likely always
fail because Bob is very likely behind NAT and we have to wait for
him to reconnect to us.

To mitigate this, we build our own buffer within the EventLoop and
send transfer proofs as soon as we are connected again.

Resolves #348.

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.

351: Show the actual BTC amount and fee to be swapped r=da-kami a=da-kami

We got user feedback, that it is confusing that the amount "found" in the wallet does not match the amount actually being swapped, thus with this PR we explicitly display the amount swapped and fees.

Merge #319
319: Alice sweeps refunded funds into default wallet r=da-kami a=da-kami

Alice's refund scenario starts with generating the temporary wallet
from keys to claim the XMR which results in Alice' unloading the wallet.
Alice then loads her original wallet to be able to handle more swaps.
Since Alice is in the role of the long running daemon handling concurrent
swaps, the operation to close, claim and re-open her default wallet must
be atomic.
This PR adds an additional step, that sweeps all the refunded XMR back into
the default wallet. In order to ensure that this is possible, Alice has to
ensure that the locked XMR got enough confirmations.
These changes allow us to assert Alice's balance after refunding.

62079fc342 Punish scenario falls back to refund or fails
If we enter a punish scenario we can be sure the punish timelock is expired.
Thus, we must be able to punish unless Bob published the refund transaction.
There is no benefit in racing punish against refund here, because we cannot recover from a punish tx failure anyway.

The logic was changed to:
Try to broadcast punish tx and await finality.
  If either punish broadcasting of finality fails, try to fetch the refund transaction.
    If it is available extract Bob's Monero key part and transition to refund.
    If refund tx is not available fail without a status update.

Note that we do not distinguish different errors upon failure of punish, because
we cannot recover anyway. If we fail to retrieve Bob's refund tx, we just exit without
a status update so punish can be retried by resuming the swap.

Simplify code within BobState::XmrLockProofReceived
To achieve this, we decompose `watch_for_locked_xmr` into two parts:

1. A non-self-consuming function to construct a `WatchRequest`
2. A state transition that can now consume `self` again because
it is only called once within the whole select! expression.

Ideally, we would move more logic onto this state transition (like
comparing the actual amounts and fail the transition if it is not
valid). Doing so would have an unfortunate side-effect: We would
always wait for the full confirmations before checking whether or
not we actually receive enough XMR.

This allows us to have state transitions that consume self.
