Upgrade python-bitcointx to 1.1.0:
Address requirements of python-bitcointx 1.1.0:
Specifically, the witness `utxo` field can no longer be
assumed to be of type CTxOut, so we should access the
CTxOut with the field witness_utxo and also when updating
the `utxo` field we now use `set_utxo()`.
Use PartiallySignedTransaction.get_fee() method.
Use PartiallySignedTransaction.set_utxo.
Additionally some minor typos/comment corrections and removal
of the now defunct `apply_freeze_signature`.
Add custom load location for libsecp where needed;
falls back to system installation if Joinmarket custom
installation is not found.
Decode error msg from server in payjoin
Cleanup test file test_proposals.txt (delete after test)
Human readable function names (names for human readable
conversions are now themselves human readable).
Remove unused get_*_vbyte functions and cleanup
Removes old unused files (electrum*.py).
Fixes core nohistory sync test to use both standard
wallet types, and fixes address import counter.
Fixes that test to use the right chain params so that
native segwit wallets can work in regtest with
nohistory mode.
Removes some now unneeded imports.
Fixes commontest.create_wallet_for_sync to hash all
parameters, including optional ones.
Replaces usage of binascii.hexlify with bintohex.
Note in particular that:
bitcoin.mktx in this PR now does support script
entries in outputs to account for nonstandard
destinations (as is needed for burn).
bitcoin.sign now supports p2wsh (as is needed
for timelocks).
Fix bug in Coins tab, get_utxos_by_mixdepth calls
Fix bug in jmbitcoin.mktx, now respects nVersion choice
Fix bug in tumbler restart wait
Fix bug in makercount for payjoin for fee check, set to 0:
The value of `options.makercount` is set to zero
so that the fee sanity check in the sendpayment script
operates approximately correctly (the receiver will bump
the fee to keep the fee rate the same if necessary).
Also the `bip79` variable is better named `payjoinurl`.
Fix bug in "freeze" context menu function in Qt
See:
https://github.com/bitcoin/bips/blob/master/bip-0078.mediawiki
Adds a new module jmclient.payjoin which implements
the full sender workflow from a BIP21 uri to a
payjoin broadcast, state is managed in JMPayjoinManager,
includes all checks as per documentation of
btcpayserver (and later, BIP78).
Added simple client and server implementations in
test/payjoinclient.py and test/payjoinserver.py
which allow a full end to end test on regtest.
Add TLS support to payjoin tests:
Note: the jmclient.payjoin module already
supports TLS by default (Agent object), but
here we add the ability to test without
certificate verification. Both test/payjoinclient.py
and test/payjoinserver.py now support TLS, but
the server needs a key and certificate in its
directory to run.
Adds BIP78 payjoin option to sendpayment.py
Users can use a bip21 uri with the "pj" field to
send a payment to a remote server.
Removes require_path_templates setting from KeyStore call
in PSBTWalletMixin.sign_psbt
Human readable representation for CTransaction
objects in jmbitcoin.secp256k1_transaction.py and for
PartiallySignedTransaction objects in jmclient.wallet.
PSBTWalletMixin, use of these in maker, taker, direct
send and in tests. Users should note that PSBT human
readable representations can in some cases be really
huge.
Update no-history-sync code:
This updates the new functionality in jmclient.wallet_utils
in the no-history-sync PR #444 to be compatible
with the python-bitcointx refactoring.
Remove all future/py2 compatibility code remaining:
This is in line with #525 and corrects erroneous
addition of more compatibility code.
Addresses all flake8 complaints (ununsed imports etc)
Addresses review of @dgpv
Addresses review of @kristapsk
Subclassed btcointx.CKeyBase to create a privkey type
that uses our signing code.
These are then used to allow signing of inputs in
transactions owned by our wallet.
Created a PSBTWalletMixin to perform the above function,
and added it to our three wallet types.
Wrote a detailed creation, sign and broadcast test
for a psbt using utxos from within and outside the wallet.
Detailed tests across all 3 wallet types for psbt
Tests cover also mixed inputs of different
types and owned/unowned. Direct send now exported to be used
in tests rather than only script usage, also supports returning
a tx object rather than only a txid.
Replaces core transaction, address, serialization
and sign functionality for Bitcoin with
python-bitcointx backend.
Removes bech32 and btscript
modules from jmbitcoin. Removes all string,
hex, binary conversion routines. A generic
hex/binary conversion now is added to jmbase.
Removes all transaction serialization and
deserialization routines. Removes the now
irrelevant test modules.
Remaining functions in jmbitcoin remove any parsing of
hex format, requiring callers to use binary only.
One additional test added, testing the remaining
function in secp256k1_transaction.py: the signing
of transactions. Deserialized form is now
bitcointx.CMutableTransaction.
For jmbase, in addition to the above, generic conversions
for utxos to and from strings is added, and a dynamic conversion
for AMP messages to binary-only. Within the code, utxos are
now only in (binarytxid, int) form, except where converted
for communcation.
Tthe largest part of the changes are
the modifications to jmbitcoin calls in jmclient;
as well as different encapsulation with CMutableTransaction,
there is also a removal of some but not all hex parsing;
it remains for rpc calls to Core and for AMP message
parsing. Backwards compatibility must be ensured so some
joinmarket protocol messages still use hex, and it is
also preserved in persistence of PoDLE data.
As part of this, some significant simplification of
certain legacy functions within the wallet has been done.
jmdaemon is entirely unaltered (save for one test which
simulates jmclient code).
Watchonly wallets use pubkeys instead of privkeys, but in a bit of
hack the functions previously called "_get_priv_from_path" would
actually return public keys for watchonly wallets. This could have
pretty terrible consequences one day, so functions like that have
been renamed to use the word "key" instead, which could be either
private or public.
The cryptoengine class BTC_Timelocked_P2WSH now implements
sign_transaction() which can be used to spend timelocked UTXOs.
FidelityBondMixin.is_timelocked_path() is now used outside the class
so its leading underscore has been removed.
Prior to this commit, if a tumbler coinjoin negotiation
failed in Phase 2, then the retry as per the logic in
taker_utils.tumbler_taker_finished_update would always
attempt to retry the transaction with those counterparties
that returned valid !sig responses. However this ignored
the case that all the counterparties responded validly,
but there was a mempool conflict in the created transaction.
After this commit, if it is detected that all counterparties
responded, it is assumed that a mempool conflict or similar
occurred with the transaction, and therefore it is better
to fallback to a schedule tweak and choose randomly again,
not to fix the counterparty set (which is likely to result
in failing again).
Prior to this commit, the user was prompted to check for
the acceptability of fees in Qt via a dialog, but settings
used in CLI (max_cj_fee_***) were not also being used the
same way in Qt.
After this commit, if the user has not added those settings,
a dialog is presented with new randomised defaults (as for
CLI), and otherwise any settings in the config file are read
and used.
The schedule format gets an extra field added denoting the number of
significant figures to round the coinjoin amounts to, with 16 meaning
no rounding.
This is part of the 2/2019 Plan to improve the privacy of JoinMarket's
tumbler script:
https://gist.github.com/chris-belcher/7e92810f07328fdfdef2ce444aad0968
Introduces WalletService object which is in control of
blockchain and wallet access.
The service manages a single transaction monitoring loop,
instead of multiple, and allows updates to the wallet from
external sources to be handled in real time, so that both Qt
and other apps (yg) can respond to deposits or withdrawals
automatically.
The refactoring also controls access to both wallet and
blockchain so that client apps (Taker, Maker) will not need
to be changed for future new versions e.g. client-side filtering.
Also updates and improves Wallet Tab behaviour in Qt (memory
of expansion state).
Additionally, blockchain sync is now --fast by default, with
the former default of detailed sync being renamed --recoversync.
Prior to this commit, there was duplicated code in maker
and taker modules to import addresses, now all calls to
the wallet for fresh addresses can optionally pass a
blockchaininterface instance and if this is done, the
new address will be imported to the BCI at the same time.
Fixes#362. Prior to this commit, if tumbler was invoked with
the --restart flag, it waited for the presence of the 0 index
output of the last seen tumbler transaction in the utxo set,
which was an unreliable indicator as that output could have,
in the meantime, been spent.
After this commit, we utilise the fact that the transaction
must be an in-wallet transaction, and use the rpc gettransaction
to check whether it has 1 or more confirmations, instead, which
should always work whether any outputs are spent or not.

Previous to this commit, the jmbitcoin package was accessed via
a file in jmclient `btc.py` which was originally added as an
interface to allow the client to use a non-jmbitcoin package to
provide the implementation; while this idea is useful, the way
it was implemented was not, moreover it is not currently used
and contained duplicated code that was unmanaged. Also, the
original usage of this was only by the electrum plugin, which
has currently been abandoned. This simplifies the code and
avoids spurious error messages. Note that most of the changes
are a result of pulling the logging function directly from the
jmbase package instead of indirectly via this interface (which
was unnecessary and not connected with jmbitcoin).
If N makers are chosen and M fail to respond with sig,
this alteration to taker code allows restart of
entire transaction with that specific subset of makers (N-M)
that originally responded honestly.
via 0 entry in num counterparties. Modify tooltip to reflect.
Rename tumble_support to taker_utils for generic Taker code.
Refactor direct_send function to that module, shared with
sendpayment CLI script.
Also add detailed function definitions for Taker callbacks in
taker.py comments. Modifications to joinmarket-qt, tumbler
working but these modifications not yet complete.
