From 0aad1f13b2430165062bf9436036c1222a8724da Mon Sep 17 00:00:00 2001 From: zathras-crypto Date: Wed, 25 Mar 2015 02:04:02 -0700 Subject: Exempt unspendable transaction outputs from dust checks Since unspendable outputs can't be spent, there is no threshold at which it would be uneconomic to spend them. This primarily targets transaction outputs with `OP_RETURN`. --- Initially based on: commit 9cf0ae26350033d43d5dd3c95054c0d1b1641eda Author: zathras-crypto Date: Wed Mar 25 02:04:02 2015 -0700 Changes: - cherry-picked on top of bitcoin:master - added RPC test for fundrawtransaction --- qa/rpc-tests/fundrawtransaction.py | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) (limited to 'qa') diff --git a/qa/rpc-tests/fundrawtransaction.py b/qa/rpc-tests/fundrawtransaction.py index 80f1d1e128..ce52247b2e 100755 --- a/qa/rpc-tests/fundrawtransaction.py +++ b/qa/rpc-tests/fundrawtransaction.py @@ -524,6 +524,22 @@ class RawTransactionsTest(BitcoinTestFramework): self.sync_all() assert_equal(oldBalance+Decimal('50.19000000'), self.nodes[0].getbalance()) #0.19+block reward + ##################################################### + # test fundrawtransaction with OP_RETURN and no vin # + ##################################################### + + rawtx = "0100000000010000000000000000066a047465737400000000" + dec_tx = self.nodes[2].decoderawtransaction(rawtx) + + assert_equal(len(dec_tx['vin']), 0) + assert_equal(len(dec_tx['vout']), 1) + + rawtxfund = self.nodes[2].fundrawtransaction(rawtx) + dec_tx = self.nodes[2].decoderawtransaction(rawtxfund['hex']) + + assert_greater_than(len(dec_tx['vin']), 0) # at least one vin + assert_equal(len(dec_tx['vout']), 2) # one change output added + if __name__ == '__main__': RawTransactionsTest().main() -- cgit v1.2.3
