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).
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
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).
