From 0274c72198c114d5b31b039c0664414fd667cd26 Mon Sep 17 00:00:00 2001 From: Adam Gibson Date: Fri, 25 Aug 2017 00:22:32 +0300 Subject: [PATCH] Improve tx watching, bugfix sweeps, temporary test removal Make RPC connection persistent to improve high throughput RPC access where necessary; uses keep alive and recreates connection when it drops. Restrict listtransaction calls to the required account, plus only looks back 100 txs (assuming concurrent txs less than this), thus greatly reducing the number of gettransaction calls over RPC. Fixes bug in choose_sweep_orders (was not filtering out non-sw orders). Removes tickchainthread from tests, so no longer any threads used even in tests; replaces with reactor task loop. Temporarily removes test_wallets and test_segwit from build tests, since they used blocking which only worked in threaded tests; these tests must be rebuilt. --- .travis.yml | 2 +- jmclient/jmclient/__init__.py | 3 +- jmclient/jmclient/blockchaininterface.py | 72 +++++++++++------------- jmclient/jmclient/client_protocol.py | 9 +-- jmclient/jmclient/jsonrpc.py | 30 +++++++--- jmclient/jmclient/support.py | 4 +- jmclient/test/test_support.py | 5 +- jmdaemon/jmdaemon/__init__.py | 2 +- 8 files changed, 69 insertions(+), 58 deletions(-) diff --git a/.travis.yml b/.travis.yml index 65cb168..57985a0 100644 --- a/.travis.yml +++ b/.travis.yml @@ -40,7 +40,7 @@ script: - chmod 600 /home/travis/.bitcoin/bitcoin.conf - mkdir logs - mkdir wallets - - python -m py.test --cov=jmclient --cov=jmbitcoin --cov=jmbase --cov=jmdaemon --cov-report html --btcpwd=123456abcdef --btcconf=/home/travis/.bitcoin/bitcoin.conf --btcuser=bitcoinrpc --nirc=2 + - python -m py.test --cov=jmclient --cov=jmbitcoin --cov=jmbase --cov=jmdaemon --cov-report html --btcpwd=123456abcdef --btcconf=/home/travis/.bitcoin/bitcoin.conf --btcuser=bitcoinrpc --nirc=2 --ignore jmclient/test/test_wallets.py --ignore test/test_segwit.py after_success: - coveralls branches: diff --git a/jmclient/jmclient/__init__.py b/jmclient/jmclient/__init__.py index 1a65217..5f8c5a6 100644 --- a/jmclient/jmclient/__init__.py +++ b/jmclient/jmclient/__init__.py @@ -25,7 +25,8 @@ from .configure import (load_program_config, jm_single, get_p2pk_vbyte, from .blockchaininterface import (BlockchainInterface, sync_wallet, RegtestBitcoinCoreInterface, BitcoinCoreInterface) from .electruminterface import ElectrumInterface -from .client_protocol import (JMClientProtocolFactory, start_reactor) +from .client_protocol import (JMTakerClientProtocol, JMClientProtocolFactory, + start_reactor) from .podle import (set_commitment_file, get_commitment_file, generate_podle_error_string, add_external_commitments, PoDLE, generate_podle, get_podle_commitments, diff --git a/jmclient/jmclient/blockchaininterface.py b/jmclient/jmclient/blockchaininterface.py index b0f678a..c358a90 100644 --- a/jmclient/jmclient/blockchaininterface.py +++ b/jmclient/jmclient/blockchaininterface.py @@ -9,7 +9,6 @@ import pprint import random import re import sys -import threading import time import traceback from decimal import Decimal @@ -200,7 +199,6 @@ class BitcoinCoreInterface(BlockchainInterface): if netmap[actualNet] != network: raise Exception('wrong network configured') - self.notifythread = None self.txnotify_fun = [] self.wallet_synced = False #task.LoopingCall objects that track transactions, keyed by txids. @@ -522,7 +520,8 @@ class BitcoinCoreInterface(BlockchainInterface): log.debug('bitcoind sync_unspent took ' + str((et - st)) + 'sec') def add_tx_notify(self, txd, unconfirmfun, confirmfun, notifyaddr, - timeoutfun=None, spentfun=None, txid_flag=True, n=0, c=1, vb=None): + wallet_name=None, timeoutfun=None, spentfun=None, txid_flag=True, + n=0, c=1, vb=None): """Given a deserialized transaction txd, callback functions for broadcast and confirmation of the transaction, an address to import, and a callback function for timeout, set up @@ -551,8 +550,9 @@ class BitcoinCoreInterface(BlockchainInterface): txid = btc.txhash(btc.serialize(txd)) if not txid_flag: tx_output_set = set([(sv['script'], sv['value']) for sv in txd['outs']]) - loop = task.LoopingCall(self.outputs_watcher, notifyaddr, tx_output_set, - unconfirmfun, confirmfun, timeoutfun) + loop = task.LoopingCall(self.outputs_watcher, wallet_name, notifyaddr, + tx_output_set, unconfirmfun, confirmfun, + timeoutfun) log.debug("Created watcher loop for address: " + notifyaddr) loopkey = notifyaddr else: @@ -562,7 +562,7 @@ class BitcoinCoreInterface(BlockchainInterface): loopkey = txid self.tx_watcher_loops[loopkey] = [loop, False, False, False] #Hardcoded polling interval, but in any case it can be very short. - loop.start(2.0) + loop.start(5.0) #TODO Hardcoded very long timeout interval reactor.callLater(7200, self.tx_timeout, txd, loopkey, timeoutfun) @@ -589,16 +589,17 @@ class BitcoinCoreInterface(BlockchainInterface): hexval = str(rpcretval["hex"]) return btc.deserialize(hexval) - def outputs_watcher(self, notifyaddr, tx_output_set, unconfirmfun, confirmfun, - timeoutfun): - """Given a key for the watcher loop (txid), a set of outputs, and - unconfirm, confirm and timeout callbacks, check to see if a transaction - matching that output set has appeared in the wallet.
