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.
Previously an example of a BIP32 path
would be: m/wallet-type'/mixdepth'/internal/index
The 'internal' name referred to internal and external addresses (also
called change and receive). The renaming to 'address_type' is in
preparation to add more branches for timelocked addresses and burner
outputs.
The variable formally known as 'internal' is now no longer a boolean
but always an integer. This almost-always seemlessly fits because the
values False and Ture correspond to 0 and 1. The function
_get_internal_type therefore has no purpose anymore. Delete it.
Fixes#477. Removes nonstandard script support
from 0.19+ bitcoind configuration for regtest and
changes scripts in test_wallet and test_tx_creation
to make them standard.
Those names as confusing. They could imply that the function obtains
a path or address given a script. To help the code be more
self-documenting I add the verb from.
To facilitate easier management by users and to
follow generally accepted standards, this PR moves

User can override location with --datadir option.
An info message is added on startup showing location.

The above commit introduces auto freezing for utxos below
a threshold, but erroneously auto freezes new utxos in
almost all cases because transactions are processed
multiple times (add_utxos handles this in the wallet).
The problem here is solved as with the same issue of
duplication in the logging of new transactions; we keep
track of new txids that arrive in the wallet and make
sure not to process the same txid twice.
Additionally, the setting of WalletService.used_addresses
is fixed. Test for this function is also fixed.
Closes#274. Utxos are disabled if they are sent
to a reused address, and are below a threshold
set by the value `max_sats_freeze_reuse` in the
`POLICY` section of the config file. If the value
is -1, such utxos are always frozen irrespective of
the value.
Users are prompted with a warning level logging message
on CLI and a popup on Joinmarket-Qt. Such disabled utxos
can of course be re-enabled by the existing methods.
Also adds test case for address reuse freezing function.
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
The tumbler schedule is split into two stages. Stage 2 is the same
as before while stage 1 attempts to fully spend each mixdepth in a
sweep coinjoin with no change address.
The wait time between these stage 1 coinjoins is longer than for
stage 2 coinjoins, the increase is determined by a new parameter
called `stage1_timelambda_increase`.

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.
This adds simple unit tests for the core functionality of
YieldGeneratorBasic in the new file jmclient/test/test_yieldgenerator.py.
The tests verify that offer creation, reannouncement of offers when a
change is made to the maxsize and translation of offers to orders works
as it should.
remove unused import
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.
Wallet persists utxo metadata; currently only
contains a field 'disabled' indexed by utxo.
User can switch this on or off (enabled) via
wallet-tool 'freeze' method.
Disabled utxos will not be used in coin
selection in any transaction.
Wallet still displays all utxo balances in
display method (and in GUI).
Add tests of disabling to test_utxomanager
Add Coins tab to Qt, with freeze/unfreeze feature.
Coins tab shows updated utxo info txid:n, amt, address and
enabled/disabled, which can be toggled from right click menu.

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).
Prior to this commit, the test function test_tumble_tweak in
jmclient/test_schedule.py would occasionally fail due to the
creation of a schedule with less than 7 transactions, resulting
in an index error when trying to tweak the remaining schedule
entries (of which there were none). Here we bump the number of
mixdepths to make this probabilistically infeasible.
