Prior to this commit, the receiver code was assuming only
2 inputs always, when it decided how to change the input
ordering (randomly doing a reversal), but this is not correct
according to the BIP78 spec, which requires that the
receiver's inputs are *inserted* randomly, without changing
the ordering of the existing (sender) inputs. After this
commit, the BIP78 protocol is adhered to for any number of
inputs.
Added test for random_insert and for payjoin with 3 inputs
Verification of message signatures against segwit addresses
is not currently functional/possible in Core, and additionally
the signing function used for messages in jmbitcoin, derived
from coincurve, was not compatible with Electrum either.
This commit uses the functionality in python-bitcointx's
signmessage module, and now the wallet method `signmessage`
creates signatures on messages against segwit addresses that
are verifiable in Electrum.
Test cases of p2sh and native are added.
This completes the task of enabling
network isolation by running the receiver
side using a hidden service in the daemon,
and communicating over AMP, as is already
the case for the sender.
Updates test_payjoin for daemon receiver.
Qt BIP78 receiver update for daemon.
In case of all-in-one (client and daemon in same process,
the default), this commit ensures that if there was a port
conflict and the port number for the daemon was incremented,
the client connects to the newly created protocol instance.
And this applies to all three protocols (jm, snicker, bip78).
This PR creates a client-daemon protocol for
the BIP78 sender, using the base protocol
`HTTPPassThrough` which provides tor and non-tor
agents with POST and GET request functionality.
As for Joinmarket coinjoins, the use of an in-process
daemon is the default option, but it can be isolated
by changing the `[DAEMON]` section of the config.
The receiver side of BIP78 will be addressed in a
future PR.
Before this commit, if receiving payjoin (BIP78) via
JoinmarketQt, after the payjoin was successfully broadcast
by the sender, and the new utxo(s) recognized in the wallet,
the Qt app nevertheless attempted to broadcast the initial
payment transaction as the delayed call was not getting canceled
by the JMBIP78ReceiverManager (this attempt of course always
failed as the coins were spent, so was not dangerous, but merely
confusing). This is now fixed.
Before this commit, the check of receiver inputs in the
proposed PSBT from the receiver was erroneously failing,
if the number of sender inputs was greater than 1, because
the list of receiver input indices was not populated correctly
before the check. This commit fixes this bug.
Prior to this commit, several test functions were using
"True" to flag internal and "False" to flag external for
the HD branch for the wallet, but we now use BaseWallet vars
ADDRESS_TYPE_[IN/EX]TERNAL (1/0), so this
is changed to explicitly reference those. There is no change
to the live code (which calls get_[internal/external]_addr).
In addition _index_cache updates in wallet are protected
with a wrapper function to ensure that the branch requested
is valid.
Tests pass both before and after this change.
... with wallet-tool method `signpsbt`. Specifically,
supports co-signing of PSBTs prepared elsewhere (so,
basic Updater/Signer and Finalizer roles, but not
Creator).
Provides detailed user feedback, command line only, and
supports broadcast of finalized transactions.
Supports native and p2sh segwit (and mixed, of course).
Also adds tests using externally prepared PSBTs.
Documentation of PSBT function added to USAGE.md.
See #772. This is likely a partial fix but that issue
may be more complex.
More generally, while we may have to process multiple
entries in the return of `listtransactions`, with the
same txid, because they may have different wallet labels,
we do not want to call `gettransaction` repeatedly on
the same txid in the same monitor loop call. Note however,
that we *do* need to call `gettransaction` again in
the next monitor loop, since the state (confirmations)
updates, so we cannot permanently cache those results.
Additionally removed redundant old_txs entries with set().
Prior to this commit, the list of used addresses,
which is required to check for address reuse, is populated
on startup in fast sync, and updated as new transactions
arrive; but if --recoversync is chosen, this list was not
originally getting populated. This commit corrects that bug.
Allow YG settings to be saved to joinmarket.cfg.
Before this commit, yield generator settings were
set inside the python script, which is not good.
After this commit, the order of precedence for the
settings for a yield generator is:
* Command line arguments, or
* Settings in [YIELDGENERATOR] in joinmarket.cfg, or
* default config settings in jmclient.configure.py
Fixes#784. In `Taker.receive_utxos` we check, in the
sweep case, whether the fee violates the user config
setting `max_sweep_fee_change`; if so, the tx is aborted,
and we shut down for single-shot coinjoins, but wait for
stallMonitor to restart for multi-schedules. The value is
defaulted to 80% to give plenty of breathing room to avoid
using up too many commitments.
Before this commit, the help message for wallet-tool was
very hard to read; this improves the format of the message
by overriding optparse's default handling of description
paragraphs, making it pass through the string exactly as is,
and also reformatting the string itself.
Fixes#778. Prior to this commit, attempting to run
sendpayment with a schedule specified with -S would
fail due to a bug. This is now fixed, and the
sendpayment help message now accurately reflects the
facts that no arguments other than the wallet name are
needed in case -S is used.
Fixes#743. The utility function `get_utxo_info`
tests the validity of the utxo string and the private
key, so there is no need to repeat this test; but we
need to add utxo data in binary format, so an option
is included to return it in this form.
The 4 ways of adding external commitments were tested
as all working after this commit: read in from json,
read in from file (csv format), read in from command
line and read from wallet.
Also fixes#741 - help message refers to correct
scriptpubkey types.
Before this commit, if an RPC connection failure occurred,
while the program is shutting down, it could raise an Exception
in the BitcoinCoreInterface.get_transaction() call triggered
by the WalletService.transaction_monitor loop. This commit
prevents that.
Fixes#736. Prior to this commit, the 'relay fee floor'
was being shown at INFO level in the command line output,
but not the actual feerate paid (in direct send scenarios;
the coinjoin scenario is rather more complex since fees are
not known before negotiation flow, but estimates are printed).
After this commit, the output at INFO level for direct
sends shows specifically the feerate and then the actual fee,
with min relay feerate relegated to DEBUG messages only, for
cases of manual feerate setting.
There is also some minor cleanup in comments and coinjoin fee
estimate messages are removed for non-coinjoins.
Before this commit, if a user specified a wallet filename argument
to `wallet-tool.py` and also one of the noseed methods 'generate',
'recover' or 'createwatchonly', it would cause a crash. This is
now checked for and a readable parser error is provided instead.
Before this commit, the taker would choose offers from
the pit based on the setting of `native` in the `[POLICY]`
section of the config object; however this could lead to
users unwittingly choosing the wrong offer type, i.e. one
that is incompatible with their own wallets, which could
result in coinjoins with mixed address types.
This commit fixes that error by only selecting offers that
are compatible with the return value of `BaseWallet.get_txtype()`.
Also fixes up tests for this wallet type enforcement.
