Old wallet format isn't used for years and script is broken since
removal of pyaes dependency. If somebody still needs it, he can use
older JoinMarket version to do conversion.
Prior to this commit, while the result of the gettransaction rpc call
was being cached so as to not have to repeat these rpc calls, the
deserialized form of the transaction created by a call to
CMutableTransaction.deserialize, was not, and since this call is rather
expensive, the history method was running more slowly than needed.
After this commit, we cache the deserialized form also, resulting in a
speedup to the wallet_utils.wallet_fetch_history method.
Fixes#1614.
Prior to this commit, if data in the persisted cache in the wallet file
were wrong (should be a very extraordinary case), then the joinmarket
code would have to crash with a cache invalid warning. After this
commit, in such an extraordinary case, the option exists to invalidate
or remove the cache on startup, so that it can be rebuilt from scratch.
This is done with a config var wallet_caching_disabled in the POLICY
section.
The algorithm in get_imported_privkey_branch was O(m*n): for each
imported path, it was iterating over the entire set of UTXOs. Rewrite
the algorithm to make one pass over the set of UTXOs up front to compute
the balance of each script (O(m)) and then, separately, one pass over
the set of imported paths to pluck out the balance for each path (O(n)).
Rather than evaluating wallet_service.get_utxos_by_mixdepth()[md],
instead evaluate wallet_service.get_utxos_at_mixdepth(md). This way
we're not computing a bunch of data that we'll immediately discard.
utxo_d = []
for k, v in disabled.items():
utxo_d.append(k)
{'frozen': True if u in utxo_d else False}
The above was inefficient. Replace with:
{'frozen': u in disabled}
Checking for existence of a key in a dict takes time proportional to
O(1), whereas checking for existence of an element in a list takes time
proportional to O(n).
Prior to this commit, an attempt to change the gap limit used in wallet
syncing, by setting gaplimit in the config via configset, would fail,
since gaplimit was only being read from command line options. After this
commit, the value of gaplimit in the POLICY section of the config,
defaulting to 6, will be read and used in Wallet object creation, either
via the createwallet or recoverwallet endpoints, or via the wallet
opening operation in the unlockwallet endpoint. This can be used in
combination with the rescanblockchain endpoint to allow discovery of
funds in addresses beyond the default gap.
PR #986 introduced two distinct balances at different levels of
the wallet tree; it serialized these balances for CLI and Qt display
but changed the RPC-API json output of the /display endpoint in a
suboptimal way. This commit fixes the json structure.
After this commit, the four levels (wallet, account, branch, entry) now
all still have balances reported under the same key as before #986, that
is, total_balance, account_balance, balance and amount, but the extra
information introduced by that PR, namely the 'available_balance' is
added as an extra key in the json dict.
Tests are added to check this structure.
For frozen balances, display a label "FROZEN" in the status notes.
For unconfirmed balances, display a label "PENDING" in the status notes.
Both FROZEN and LOCKED balances are considered unavailable balances, while PENDING balance is considered available balance.
Because it is possible to broadcast a transaction that spends unconfirmed balance, while a user has to manually unfreeze
the balance or wait until the timelock has expired before they can use FROZEN or LOCKED balances.
If a user has many UTXOs but wants to spend just one, they would have
to freeze all the UTXOs one-by-one except for one, then after sending
do the same again unfreezing all UTXOs one-by-one. This new command
drastically speeds up this process.
Fixes#1143 (and possibly others). Before this commit,
(index plus gap limit) addresses are imported on sync,
and addresses used by maker/taker in coinjoin are imported,
but when a deposit occurred, bumping the index, further
addresses were not imported. The effect was that it was
possible, if doing a series of deposits to multiple
external addresses in a Qt session, to end up depositing
to an address that was not yet imported. And this results
in the user needing to rescan for Core+JM to recognize the
coins.
After this commit, we ensure all 'gap limit forwards'
addresses, which are displayed as potential deposit addresses
in Joinmarket-Qt, are imported before the display.
Fixes#1118.
Before this commit, the json serializtion of a
WalletEntry object was incorrect and missing some
fields. This is now fixed, and the WalletDisplayResponse
in the RPC spec .yaml file correctly reflects the
fields that are returned by the JMWalletDaemon in response
to the /display request.
Fixes#1043.
Prior to this commit, only keys/scripts/addresses
inside the scope of the current wallet script_map
(the keys cached by sync, according to persisted
index in wallet file, including gap limit) would
allow a successful signing operation, otherwise
an assertion was raised.
After this commit, signing can be done with any
arbitrary height index in the wallet (assuming a
valid path for this wallet).
1. Moves the JMWalletDaemon service class into
the jmclient package (see the wallet_rpc.py module).
2. Adds dependencies "klein" and "autobahn" to the
jmclient package, as well as "pyjwt".
3. Adds another module websocketserver.py, using
autobahn, to allow the JMWalletDaemon service to
serve subscriptions over a websocket, for e.g.
transaction notifications.
4. Adds tests both for the websocket connection
and for the JSON-RPC HTTP connection.
JmwalletdWebSocketServerFactory.sendTxNotification
sends the json-ified transaction details using
jmbitcoin.human_readable_transaction (as is currently
used in our CLI), along with the txid.
Also adds a coinjoin state update event sent via
the websocket (switch from taker/maker/none).
Require authentication to connect to websocket.
5. Add OpenApi definition of API in yaml;
also auto-create human-readable API docs in markdown.
6. Add fidelity bond function to API
7. Add config read/write route to API
8. Remove snicker rpc calls temporarily
9. Updates to docoinjoin: corrects taker_finished
for this custom case, does not shut down at end.
10. Address detailed review comments of @PulpCattel.
Uses Klein to provide HTTP server support.
Adds cookie based auth to requests (made JWT token
based in later commits).
Basic routes are: /unlock, /lock, /display,
/create of wallet.
Encapsulates WalletDaemon as a Service
Add snicker receiver service start, stop
Adds yg/maker function as stoppable service.
Adds a JMShutdown command to
the AMP protocol, allowing a clean shutdown
of a long running bot (e.g. maker) by shutting
down its message channel connections, without
shutting down the entire process.
Adds payment(direct send) request, first draft
This ensures that `wallet_utils.py` and `genwallet.py` use the same logic for
reading the password.
The current algorithm for reading the password entails some
non-obvious details like utf-8 encoding and not stripping trailing
newlines.
