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 refactors YieldGeneratorBasic a bit. In particular, we move things
that custom algorithms will most likely want to change to separate
functions. That way, it is easy to define the behaviour of inputs
and outputs for the join without the need to duplicate the other, more
general logic of create_my_orders and oid_to_order.
Prior to this commit, if an invalid destination address
was entered on the command line for the tumbler script,
the invalidity would cause a crash at the time a transaction
was built with this destination (during the run).
After this commit, all destination addresses entered on
startup are checked immediately and the program quits with
this information if a specific address is invalid.
In commit 22467f4 a bug was introduced whereby detailed
sync was used instead of fast sync, but with only one
iteration, in Joinmarket-Qt, in certain circumstances,
leading to incorrect wallet reporting/display. This commit
reverts that change (except for function name change).
There may still be edge cases for large wallets doing
recovery in Qt but this will be dealt with later.
af11116 Estimate tx fees for sendpayment or full tumbler run and warn the user if the tx fee estimation exceeds 5% of the funds to be coinjoined/tumbled. (AlexCato)
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.
after restarts, instead of sending coins back to wallet.
This is a fix for #363.
Prior to this commit, if a tumbler
run was restarted on command line with --restart, and a schedule
entry failed triggering a call of tweak_tumble_schedule, the
destination address was always reset with INTERNAL to another in-
wallet address, even if it was actually an outward destination
address, because the restart of the tumbler script created an
instance of Taker without any addresses stored in the variable
tdestaddrs. After this commit, the Taker instance is instantiated
with the remaining destination addresses in the post-restart
schedule.
The user is prompted with a warning if they use --restart in
combination with command line destination addresses; they are
warned that the latter will be ignored, since the contents of the
schedule file are respected, instead.
2cb5df4 Output full path/file name of lockfile in a case of lock (Kristaps Kaupe)
5ffa950 Better default column sizes in "JM Wallet" tab (Kristaps Kaupe)
Previous to this commit, selecting a new schedule file would
not "correctly" detect that an unfinished tumble run was selected
(note that this "detection" is currently just checking the
name of the file, so it may have to be changed in future). The
reason for the failure to detect is that in the PyQt5 version,
the filenames are returned as a tuple, and so the str() conversion
did not match.
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, a user could create a direct payment or
Joinmarket coinjoin inadvertently by not using the correct arguments
to sendpayment.py (missing -T or setting -N0). After this commit,
the correct number of arguments (3) are insisted on, and -T takes
precedence over -N 0.
