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).
To facilitate easier management by users and to
follow generally accepted standards, this PR moves
the following all to user home directory, subdir
.joinmarket :
joinmarket.cfg file
wallets/ directory
logs/ directory
cmtdata/ directory
commitmentlist file
User can override location with --datadir option.
An info message is added on startup showing location.
In the Python3 compatibility upgrade, jmbase.support.getpassword
was changed and now returns bytes, therefore the password should
not be utf-8 encoded in the function decrypt_wallet_data. Without
this change, the conversion script errors; this fixes that error.
