Decomposing a RequestResponseEvent is quite verbose. We can introduce
a helper function that does the matching for us and delegates to
specific `From` implementations for the protocol specific bits.

339: Bump dependency versions r=thomaseizinger a=thomaseizinger
Otherwise it will take a long time for dependabot to update all of
these.
Co-authored-by: Thomas Eizinger <thomas@eizinger.io>
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.
Co-authored-by: Daniel Karzel <daniel@comit.network>
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.
Co-authored-by: Daniel Karzel <daniel@comit.network>
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.
325: Misc cleanup r=thomaseizinger a=thomaseizinger
Miscellaneous cleanups of the `swap`, `state` and `steps` modules.

Since 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.
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.
Instead of calling this function in all the branches, we can simply
make the whole match statement evaluate to the new state and perform
this functionality at the very end.
This allows us to move critical crypto logic onto `State3` which
holds all the necessary data which consequently allows us to get
rid of `lock_xmr` altogether by inlining it into the swap function.
The reduced indirection improves readability.
337: Update the preview release text r=thomaseizinger a=thomaseizinger
By default, GitHub uses the last commit message as the body text.
This can be a lot of text if the last commit was from dependabot.
Make the preview release more pleasant to look at by adding a
dedicated body.
