From 05e82d86b09d914ebce05dbc92a7299cb026847b Mon Sep 17 00:00:00 2001 From: Jon Atack Date: Thu, 12 Nov 2020 11:16:48 +0100 Subject: wallet: override minfee checks (fOverrideFeeRate) for fee_rate in RPCs fundrawtransaction and walletcreatefundedpsbt only. This provides the existing feeRate (BTC/kvB) behavior in these two RPCs to the new fee_rate (sat/vB) param also. See these two GitHub review discussions for more info: https://github.com/bitcoin/bitcoin/pull/10706/#discussion_r126560525 https://github.com/bitcoin/bitcoin/pull/20305#discussion_r520032533 --- test/functional/rpc_fundrawtransaction.py | 11 ++++------- test/functional/rpc_psbt.py | 12 ++++++------ 2 files changed, 10 insertions(+), 13 deletions(-) (limited to 'test') diff --git a/test/functional/rpc_fundrawtransaction.py b/test/functional/rpc_fundrawtransaction.py index d515b4a7d3..f987867e61 100755 --- a/test/functional/rpc_fundrawtransaction.py +++ b/test/functional/rpc_fundrawtransaction.py @@ -752,7 +752,7 @@ class RawTransactionsTest(BitcoinTestFramework): node.fundrawtransaction, rawtx, {"estimate_mode": mode, "conf_target": n, "add_inputs": True}) self.log.info("Test invalid fee rate settings") - assert_raises_rpc_error(-4, "Fee rate (0.000 sat/vB) is lower than the minimum fee rate setting (1.000 sat/vB)", + assert_raises_rpc_error(-8, "Invalid fee_rate 0.000 sat/vB (must be greater than 0)", node.fundrawtransaction, rawtx, {"fee_rate": 0, "add_inputs": True}) assert_raises_rpc_error(-8, "Invalid feeRate 0.00000000 BTC/kvB (must be greater than 0)", node.fundrawtransaction, rawtx, {"feeRate": 0, "add_inputs": True}) @@ -766,12 +766,9 @@ class RawTransactionsTest(BitcoinTestFramework): assert_raises_rpc_error(-3, "Invalid amount", node.fundrawtransaction, rawtx, {"fee_rate": "", "add_inputs": True}) - # Test setting explicit fee rate just below the minimum. - self.log.info("- raises RPC error 'fee rate too low' if fee_rate of 0.99999999 sat/vB is passed") - msg = "Fee rate (0.999 sat/vB) is lower than the minimum fee rate setting (1.000 sat/vB)" - assert_raises_rpc_error(-4, msg, node.fundrawtransaction, rawtx, {"fee_rate": 0.99999999, "add_inputs": True}) - # This feeRate test only passes if `coinControl.fOverrideFeeRate = true` in wallet/rpcwallet.cpp::FundTransaction is removed. - # assert_raises_rpc_error(-4, msg, node.fundrawtransaction, rawtx, {"feeRate": 0.00000999, "add_inputs": True}) + self.log.info("Test min fee rate checks are bypassed with fundrawtxn, e.g. a fee_rate under 1 sat/vB is allowed") + node.fundrawtransaction(rawtx, {"fee_rate": 0.99999999, "add_inputs": True}) + node.fundrawtransaction(rawtx, {"feeRate": 0.00000999, "add_inputs": True}) self.log.info("- raises RPC error if both feeRate and fee_rate are passed") assert_raises_rpc_error(-8, "Cannot specify both fee_rate (sat/vB) and feeRate (BTC/kvB)", diff --git a/test/functional/rpc_psbt.py b/test/functional/rpc_psbt.py index 313611ca17..498197b5e5 100755 --- a/test/functional/rpc_psbt.py +++ b/test/functional/rpc_psbt.py @@ -192,9 +192,14 @@ class PSBTTest(BitcoinTestFramework): assert_approx(res1["fee"], 0.055, 0.005) res2 = self.nodes[1].walletcreatefundedpsbt(inputs, outputs, 0, {"feeRate": 0.1, "add_inputs": True}) assert_approx(res2["fee"], 0.055, 0.005) + self.log.info("Test min fee rate checks with walletcreatefundedpsbt are bypassed, e.g. a fee_rate under 1 sat/vB is allowed") + res3 = self.nodes[1].walletcreatefundedpsbt(inputs, outputs, 0, {"fee_rate": 0.99999999, "add_inputs": True}) + assert_approx(res3["fee"], 0.00000381, 0.0000001) + res4 = self.nodes[1].walletcreatefundedpsbt(inputs, outputs, 0, {"feeRate": 0.00000999, "add_inputs": True}) + assert_approx(res4["fee"], 0.00000381, 0.0000001) self.log.info("Test invalid fee rate settings") - assert_raises_rpc_error(-4, "Fee rate (0.000 sat/vB) is lower than the minimum fee rate setting (1.000 sat/vB)", + assert_raises_rpc_error(-8, "Invalid fee_rate 0.000 sat/vB (must be greater than 0)", self.nodes[1].walletcreatefundedpsbt, inputs, outputs, 0, {"fee_rate": 0, "add_inputs": True}) assert_raises_rpc_error(-8, "Invalid feeRate 0.00000000 BTC/kvB (must be greater than 0)", self.nodes[1].walletcreatefundedpsbt, inputs, outputs, 0, {"feeRate": 0, "add_inputs": True}) @@ -244,11 +249,6 @@ class PSBTTest(BitcoinTestFramework): assert_raises_rpc_error(-8, "Invalid conf_target, must be between 1 and 1008", # max value of 1008 per src/policy/fees.h self.nodes[1].walletcreatefundedpsbt, inputs, outputs, 0, {"estimate_mode": mode, "conf_target": n, "add_inputs": True}) - # Test setting explicit fee rate just below the minimum. - self.log.info("- raises RPC error 'fee rate too low' if feerate_sat_vb of 0.99999999 is passed") - assert_raises_rpc_error(-4, "Fee rate (0.999 sat/vB) is lower than the minimum fee rate setting (1.000 sat/vB)", - self.nodes[1].walletcreatefundedpsbt, inputs, outputs, 0, {"fee_rate": 0.99999999, "add_inputs": True}) - self.log.info("Test walletcreatefundedpsbt with too-high fee rate produces total fee well above -maxtxfee and raises RPC error") # previously this was silently capped at -maxtxfee for bool_add, outputs_array in {True: outputs, False: [{self.nodes[1].getnewaddress(): 1}]}.items(): -- cgit v1.2.3
