Previously, the time was formatted as ISO8601 timestamps which is
barely readable by humans. Activating the `chrono` feature allows
us to format with a different format string. The output now looks
like this:
2021-03-01 11:59:52 DEBUG Database and seed will be stored in /home/thomas/.local/share/xmr-btc-swap
2021-03-01 11:59:52 DEBUG Starting monero-wallet-rpc on port 40673
2021-03-01 11:59:59 DEBUG Still got 0.00009235 BTC left in wallet, swapping ...
2021-03-01 11:59:59 DEBUG Dialing alice at 12D3KooWCdMKjesXMJz1SiZ7HgotrxuqhQJbP5sgBm2BwP1cqThi
2021-03-01 11:59:59 DEBUG Requesting quote for 0.00008795 BTC
There is a double space after the time which is already fixed in
tracing-subscriber but not yet released.
See https://github.com/tokio-rs/tracing/issues/1271.
If the monero wallet rpc has not already been downloaded we download the monero cli package and extract the wallet rpc. The unneeded files are cleaned up. The monero wallet rpc is started on a random port which is provided to the swap cli.
We added a fork of tokio-tar via a git subtree because we needed a tokio-tar version that was compatible with tokio 1.0. Remove this subtree in favor of a regular cargo dependency when this PR merges: https://github.com/vorot93/tokio-tar/pull/3.
By updating `tracing_log`, we can access the re-export. That we need
to initialize the `tracing_log` adaptor.
The usage of `log::LevelFilter` for the `init_tracing` function was
conceptually incorrect. We should be using a type from the `tracing`
library here.
To achieve this we also:
- upgrade rust-bitcoin to 0.26
- upgrade bitcoin-harness to latest version (which also depends bitcoin 0.26)
- upgrade to latest edcsa-fun
- replace cross_curve_dleq proof with sigma_fun (to avoid an upgrade dance over there)
The bitcoind wallet required the user to run a bitcoind node. It was replaced with a bdk wallet which allows the user to connect to an electrum instance hosted remotely. An electrum and bitcoind testcontainer were created to the test the bdk wallet. The electrum container reads the blockdata from the bitcoind testcontainer through a shared volume. bitcoind-harness was removed as bitcoind initialisation code was moved into test_utils. The bdk wallet differs from the bitcoind wallet in that it needs to be manually synced with an electrum node. We synchronise the wallet once upon initialisation to prevent a potentially long running blocking task from interrupting protocol execution. The electrum HTTP API was used to get the latest block height and the transaction block height as this functionality was not present in the bdk wallet API or it required the bdk wallet to be re-synced to get an up to date value.
Upgrade bitcoin harness dependency to latest commit
Upgrade backoff to fix failing tests. The previous version of backoff had a broken version of the retry function. Upgraded to a newer comit which fixes this problem.
Upgrade hyper to 0.14 as the 0.13 was bringing in tokio 0.2.24
Upgraded bitcoin harness to version that uses tokio 1.0 and reqwest 0.11
Upgrade reqwest to 0.11. Reqwest 0.11 uses tokio 1.0
Upgrade libp2p to 0.34 in preparation for tokio 1.0 upgrade
This includes the introduction of the --data-dir parameter instead of the --database.
Both the seed file and the database are stored in the data-dir, the database in sub-folder `database`.
Created network, storage and protocol modules. Organised
files into the modules where the belong.
xmr_btc crate moved into isolated modulein swap crate.
Remove the xmr_btc module and integrate into swap crate.
Consolidate message related code
Reorganise imports
Remove unused parent Message enum
Remove unused parent State enum
Remove unused dependencies from Cargo.toml
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
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.
The numerous tor conditional compile flags were removed by
extracting transport creation to the main statement. A tor
transport is created if Alice specifies a tor port using the CLI.
