From d20d7567528e216badb8475df298bb3cec008985 Mon Sep 17 00:00:00 2001 From: Felix Weis Date: Fri, 10 May 2019 08:21:52 -0400 Subject: rpc: faster getblockstats using BlockUndo data Using undo data for a block (rev?????.dat) we can retrieve value information about prevouts and calculate the final transaction fee (rate). This approach is about 80x faster, drops the requirement for -txindex, and works for all non-pruned blocks. --- test/functional/rpc_getblockstats.py | 45 +++++++++--------------------------- 1 file changed, 11 insertions(+), 34 deletions(-) (limited to 'test/functional/rpc_getblockstats.py') diff --git a/test/functional/rpc_getblockstats.py b/test/functional/rpc_getblockstats.py index e17a8f6421..efab69ac26 100755 --- a/test/functional/rpc_getblockstats.py +++ b/test/functional/rpc_getblockstats.py @@ -13,7 +13,6 @@ from test_framework.util import ( ) import json import os -import time TESTSDIR = os.path.dirname(os.path.realpath(__file__)) @@ -21,18 +20,6 @@ class GetblockstatsTest(BitcoinTestFramework): start_height = 101 max_stat_pos = 2 - STATS_NEED_TXINDEX = [ - 'avgfee', - 'avgfeerate', - 'maxfee', - 'maxfeerate', - 'medianfee', - 'feerate_percentiles', - 'minfee', - 'minfeerate', - 'totalfee', - 'utxo_size_inc', - ] def add_options(self, parser): parser.add_argument('--gen-test-data', dest='gen_test_data', @@ -44,24 +31,26 @@ class GetblockstatsTest(BitcoinTestFramework): help='Test data file') def set_test_params(self): - self.num_nodes = 2 - self.extra_args = [['-txindex'], ['-paytxfee=0.003']] + self.num_nodes = 1 self.setup_clean_chain = True def get_stats(self): return [self.nodes[0].getblockstats(hash_or_height=self.start_height + i) for i in range(self.max_stat_pos+1)] def generate_test_data(self, filename): - mocktime = time.time() + mocktime = 1525107225 + self.nodes[0].setmocktime(mocktime) self.nodes[0].generate(101) - self.nodes[0].sendtoaddress(address=self.nodes[1].getnewaddress(), amount=10, subtractfeefromamount=True) + address = self.nodes[0].get_deterministic_priv_key().address + self.nodes[0].sendtoaddress(address=address, amount=10, subtractfeefromamount=True) self.nodes[0].generate(1) self.sync_all() - self.nodes[0].sendtoaddress(address=self.nodes[0].getnewaddress(), amount=10, subtractfeefromamount=True) - self.nodes[0].sendtoaddress(address=self.nodes[0].getnewaddress(), amount=10, subtractfeefromamount=False) - self.nodes[1].sendtoaddress(address=self.nodes[0].getnewaddress(), amount=1, subtractfeefromamount=True) + self.nodes[0].sendtoaddress(address=address, amount=10, subtractfeefromamount=True) + self.nodes[0].sendtoaddress(address=address, amount=10, subtractfeefromamount=False) + self.nodes[0].settxfee(amount=0.003) + self.nodes[0].sendtoaddress(address=address, amount=1, subtractfeefromamount=True) self.sync_all() self.nodes[0].generate(1) @@ -93,11 +82,12 @@ class GetblockstatsTest(BitcoinTestFramework): # Set the timestamps from the file so that the nodes can get out of Initial Block Download self.nodes[0].setmocktime(mocktime) - self.nodes[1].setmocktime(mocktime) + self.sync_all() for b in blocks: self.nodes[0].submitblock(b) + def run_test(self): test_data = os.path.join(TESTSDIR, self.options.test_data) if self.options.gen_test_data: @@ -107,9 +97,6 @@ class GetblockstatsTest(BitcoinTestFramework): self.sync_all() stats = self.get_stats() - expected_stats_noindex = [] - for stat_row in stats: - expected_stats_noindex.append({k: v for k, v in stat_row.items() if k not in self.STATS_NEED_TXINDEX}) # Make sure all valid statistics are included but nothing else is expected_keys = self.expected_stats[0].keys() @@ -127,10 +114,6 @@ class GetblockstatsTest(BitcoinTestFramework): stats_by_hash = self.nodes[0].getblockstats(hash_or_height=blockhash) assert_equal(stats_by_hash, self.expected_stats[i]) - # Check with the node that has no txindex - stats_no_txindex = self.nodes[1].getblockstats(hash_or_height=blockhash, stats=list(expected_stats_noindex[i].keys())) - assert_equal(stats_no_txindex, expected_stats_noindex[i]) - # Make sure each stat can be queried on its own for stat in expected_keys: for i in range(self.max_stat_pos+1): @@ -168,12 +151,6 @@ class GetblockstatsTest(BitcoinTestFramework): # Make sure we aren't always returning inv_sel_stat as the culprit stat assert_raises_rpc_error(-8, 'Invalid selected statistic aaa%s' % inv_sel_stat, self.nodes[0].getblockstats, hash_or_height=1, stats=['minfee' , 'aaa%s' % inv_sel_stat]) - - assert_raises_rpc_error(-8, 'One or more of the selected stats requires -txindex enabled', - self.nodes[1].getblockstats, hash_or_height=1) - assert_raises_rpc_error(-8, 'One or more of the selected stats requires -txindex enabled', - self.nodes[1].getblockstats, hash_or_height=self.start_height + self.max_stat_pos) - # Mainchain's genesis block shouldn't be found on regtest assert_raises_rpc_error(-5, 'Block not found', self.nodes[0].getblockstats, hash_or_height='000000000019d6689c085ae165831e934ff763ae46a2a6c172b3f1b60a8ce26f') -- cgit v1.2.3
