Closes#1247.
This consists of an inclusion of the bond value exponent into the config
that the user can alter, and a change of that from 2 to default 1.3.
Also updates the fidelity bond documentation to account for those
changes, including the units used in ob-watcher, but not the calculation
of fidelity bond attack resistance (which remains a TODO).
Prior to this commit, running ob-watcher with
an onion-type message channel configured would result
in the bot attempting to connect to all the makers,
which is bad. This happened because the internal logic
of the onion message channel is that receivers of privmsgs
will be sent peer info from the directory, so that they can
immediately respond p2p if they succeed in outward connecting.
But for bots who do not intend to engage in a coinjoin interactive
protocol, like ob-watchers, this is absolutely not the desired outcome.
After this commit, a bot can specify mode "PASSIVE" in the call to
get_mchannels(), which results in the OnionMessageChannel object only
creating non-directory remote peer objects of type OnionPeerPassive,
instead of OnionPeer, which means they never try to connect to those
remote peers.
Also, exports JMMakerClientProtocol for custom directory node scripts
(stored in the custom-scripts repo).
Modify default config with 2 signet and mainnet directory nodes to
start.
Handles unreachable directory nodes with a human readable error and
adjusts connection timeouts to be realistic.
Changes wording in Qt notifications from "IRC" to message channel.
Updates docs, new directory node information.
In the previous commit, all peers served an onion.
After this commit, taker client instances will automatically
send a config var to the jmdaemon backend that instructs
the OnionMessageChannel instance to not start an onion service,
and the handshake messages sent by these peers replace the
onion location with a placeholder string NOT-SERVING-ONION.
Directories and maker peers will not therefore to connect outbound
to them, but privmsging still happens p2p with connections from
takers to makers after the directory has communicated their
reachable .onion addresses.
This change reduces the configuration requirement for takers and
is better for their privacy and security (without sacrificing
the gain we get from having p2p connections).
The above comments re: takers also apply to ob-watcher bots.
This commit also fixes a large number of minor bugs and errors in
documentation, as well as many Python cleanups after review from
@PulpCattel. A few concrete items are:
It fixes the ob-watcher functionality to work with the new subclass
of MessageChannel (OnionMessageChannel).
It corrects the on_nick_leave trigger to make dynamic nick switching
between MessageChannels (as implemented in MessageChannelCollection)
work correctly.
It corrects the order of events in the add_peer workflow to ensure that
a handshake can always be sent so that the activation of the connection
always works.
It sets a default messaging config with onion, 2 active IRC servers and
one inactive IRC server. The onion config has 2 signet directory nodes,
so this will change to mainnet after the PR is merged to master.
Joinmarket bots run their own onion services allowing inbound connections.
Both takers and makers connect to other makers at the mentioned
onion services, over Tor.
Directory nodes run persistent onion services allowing peers to
find other (maker) peers to connect to, and also forwarding
messages where necessary.
This is implemented as an alternative to IRC, i.e. a new
implementation of the abstract class MessageChannel, in onionmc.py.
Note that using both this *and* IRC servers is supported; Joinmarket
supports multiple, redundant different communication methods,
simultaneously.
Messaging is done with a derived class of twisted's LineReceiver,
and there is an additional layer of syntax, similar to but not the
same as the IRC syntax for ensuring that messages are passed with
the same J5.. nick as is used on IRC. This allows us to keep the
message signing logic the same as before. As well as Joinmarket line
messages, we use additional control messages to communicate peer lists,
and to manage connections.
Peers which send messages not conforming to the syntax are dropped.
See https://github.com/JoinMarket-Org/JoinMarket-Docs/pull/12 for
documentation of the syntax.
Connections to directory nodes are robust as for IRC servers, in
that we use a ReconnectingClientFactory to keep trying to re-establish
broken connections with exponential backoff. Connections to maker
peers do not require this feature, as they will often disconnect
in normal operation.
Multiple directory nodes can and should be configured by bots.
Fixes#1162.
Prior to this commit, the default argument [] was provided
to the bitcoind RPC listunspent call, which means only confirmed
unspent coins are returned. This is in contrast to the display
in wallet_tool, which deliberately updates listunspent_args to [0]
in order to default to showing unconfirmed coins, as users will
expect.
This commit adds the same listunspent_args = [0] in case the user
has not edited this variable in the config, for the same reason.
Fixes#1024.
Prior to this commit, if the RPC connection were lost
while JoinmarketQt was running, the reactor would be
stopped, but the qt5reactor shutdown does not stop
the Qt Application. This commit fixes that by injecting
a custom reactor stop function wrapper into jmbase,
which triggers the close event of the Qt main window.
Fixes#1060.
Prior to this commit, the extra log for tumbler.py
was created in the local directory, because it was
set before running load_program_config (which defaults
to the user's default joinmarket config location), this
is now corrected.
When open wallet from menu, also use the JMOpenWalletDialog to handle the workflow
Create a new "errorMessageLabel" in the OpenWalletDialog, and show the error message in this new label instead of in a separate message box popup.
Auto focus on passphraseEdit when OpenWalletDialog is launched, and when a wallet file has been chosen
1. Moves the JMWalletDaemon service class into
the jmclient package (see the wallet_rpc.py module).
2. Adds dependencies "klein" and "autobahn" to the
jmclient package, as well as "pyjwt".
3. Adds another module websocketserver.py, using
autobahn, to allow the JMWalletDaemon service to
serve subscriptions over a websocket, for e.g.
transaction notifications.
4. Adds tests both for the websocket connection
and for the JSON-RPC HTTP connection.
JmwalletdWebSocketServerFactory.sendTxNotification
sends the json-ified transaction details using
jmbitcoin.human_readable_transaction (as is currently
used in our CLI), along with the txid.
Also adds a coinjoin state update event sent via
the websocket (switch from taker/maker/none).
Require authentication to connect to websocket.
5. Add OpenApi definition of API in yaml;
also auto-create human-readable API docs in markdown.
6. Add fidelity bond function to API
7. Add config read/write route to API
8. Remove snicker rpc calls temporarily
9. Updates to docoinjoin: corrects taker_finished
for this custom case, does not shut down at end.
10. Address detailed review comments of @PulpCattel.
The /utxos route is the equivalent of the showutxos
wallet tool method.
The heartbeat route /session allows a client to
make sure the backend is still running and in the
expected state (but see later commits for the
coinjoin state update via the websocket).
Fixes to sendpayment, the maker service,
the create wallet function.
sendpayment fix
Also substantially improved and made
functional the coinjoin route, a schedule
is now created and a complete taker-side
coinjoin is now possible.
Uses Klein to provide HTTP server support.
Adds cookie based auth to requests (made JWT token
based in later commits).
Basic routes are: /unlock, /lock, /display,
/create of wallet.
Encapsulates WalletDaemon as a Service
Add snicker receiver service start, stop
Adds yg/maker function as stoppable service.
Adds a JMShutdown command to
the AMP protocol, allowing a clean shutdown
of a long running bot (e.g. maker) by shutting
down its message channel connections, without
shutting down the entire process.
Adds payment(direct send) request, first draft
Before this commit, the ob-watcher.py script errored
in trying to read offers because the variable
dust_threshold of the OrderbookWatch class was not
initialized; this was because this variable is now
set by the client in the AMP message JMInit; but
ob-watcher is a script that runs without any such
client. Since the script has access to the global
configuration from the jmclient package anyway, the
fix is just to add that into the ObBasic class
constructor.
This ensures that `wallet_utils.py` and `genwallet.py` use the same logic for
reading the password.
The current algorithm for reading the password entails some
non-obvious details like utf-8 encoding and not stripping trailing
newlines.
Changes from top to bottom:
- Add header comment
- Import wallet_utils (needed for DEFAULT_MIXDEPTH)
- Make password optional in usage string
- Set variable wallet_name at the top where options are parsed
- Use DEFAULT_MIXDEPTH instead of hardcoded value
bugfix: use enumerate instead of len
reviewed estimation of transaction sizes
estimates are still a bit conservative with room for improvement;
signatures could still save up to one byte each if using low-r
values. python-bitcointx==1.1.2-dev already supports grinding for
low-r values so when it's stable and referenced version is updated,
this should be reviewed again so as to utilize that benefit.
added utility method `estimate_extra_bytes`
the purpose of this method is for the computation
of extra bytes when the coinjoin or direct send output
type is different from that of the wallet
updated tests to reflect new transaction size
computation
p2pkh transactions are now 1 byte larger for
the inputs hence the change amount should be
less 4 * 30 sats.
add private keys for utxos that we may not be
tracking
some transactions (e.g. opt-in rbf) may require signing
with private keys for utxos that we may have stopped
tracking. this commit will search through all inputs
and for those we own and retrieve their private keys
so we can sign with them.
added support for p2wsh output scripts in
refactored the estimation of the transaction size
when outputs of a different type is the target
Previously, a different method was employed which
was kind of kludgy considering the fact that the
`extra_bytes` parameter is really for `OP_RETURN`
outputs. This method modifies the `estimate_tx_size`
method to accept an optional extra parameter called
`outtype` which is used to estimate the correct
transaction size if the target output is different
from that of the wallet.
added missing import
added a note about preserving the order of wallet type constants
Fix bug with timelocked addrs in receive payjoin
Previously there would be a crash if the wallet receiving a payjoin
had a timelocked UTXO.
