From 2fffaa97381f741786fff2e6ff25f4b9a74037fe Mon Sep 17 00:00:00 2001 From: Alex Morcos Date: Thu, 29 Jun 2017 11:29:34 -0400 Subject: [PATCH] Make QT fee displays use GetMinimumFee instead of estimateSmartFee Remove helper function (CalculateEstimateType) for determining whether estimates should be conservative or not, now that this is only called once from GetMinimumFee and incorporate the logic directly there. --- src/qt/coincontroldialog.cpp | 10 ++-------- src/qt/sendcoinsdialog.cpp | 16 ++++++---------- src/wallet/coincontrol.h | 4 ++-- src/wallet/wallet.cpp | 17 ++++------------- src/wallet/wallet.h | 2 -- 5 files changed, 14 insertions(+), 35 deletions(-) diff --git a/src/qt/coincontroldialog.cpp b/src/qt/coincontroldialog.cpp index 7d8ef6571..f3ee0fbe3 100644 --- a/src/qt/coincontroldialog.cpp +++ b/src/qt/coincontroldialog.cpp @@ -490,8 +490,6 @@ void CoinControlDialog::updateLabels(WalletModel *model, QDialog* dialog) else nBytesInputs += 148; } - bool conservative_estimate = CalculateEstimateType(FeeEstimateMode::UNSET, coinControl->signalRbf); - // calculation if (nQuantity > 0) { @@ -583,12 +581,8 @@ void CoinControlDialog::updateLabels(WalletModel *model, QDialog* dialog) QString toolTipDust = tr("This label turns red if any recipient receives an amount smaller than the current dust threshold."); // how many satoshis the estimated fee can vary per byte we guess wrong - double dFeeVary; - if (payTxFee.GetFeePerK() > 0) - dFeeVary = (double)std::max(CWallet::GetRequiredFee(1000), payTxFee.GetFeePerK()) / 1000; - else { - dFeeVary = (double)std::max(CWallet::GetRequiredFee(1000), ::feeEstimator.estimateSmartFee(*coinControl->m_confirm_target, NULL, ::mempool, conservative_estimate).GetFeePerK()) / 1000; - } + double dFeeVary = (double)nPayFee / nBytes; + QString toolTip4 = tr("Can vary +/- %1 satoshi(s) per input.").arg(dFeeVary); l3->setToolTip(toolTip4); diff --git a/src/qt/sendcoinsdialog.cpp b/src/qt/sendcoinsdialog.cpp index d48b3753b..a01886c3e 100644 --- a/src/qt/sendcoinsdialog.cpp +++ b/src/qt/sendcoinsdialog.cpp @@ -652,7 +652,7 @@ void SendCoinsDialog::updateCoinControlState(CCoinControl& ctrl) if (ui->radioCustomFee->isChecked()) { ctrl.m_feerate = CFeeRate(ui->customFee->value()); } else { - ctrl.m_feerate = boost::none; + ctrl.m_feerate.reset(); } // Avoid using global defaults when sending money from the GUI // Either custom fee will be used or if not selected, the confirmation target from dropdown box @@ -666,15 +666,13 @@ void SendCoinsDialog::updateSmartFeeLabel() return; CCoinControl coin_control; updateCoinControlState(coin_control); - coin_control.m_feerate = boost::none; // Explicitly use only fee estimation rate for smart fee labels + coin_control.m_feerate.reset(); // Explicitly use only fee estimation rate for smart fee labels FeeCalculation feeCalc; - bool conservative_estimate = CalculateEstimateType(FeeEstimateMode::UNSET, coin_control.signalRbf); - CFeeRate feeRate = ::feeEstimator.estimateSmartFee(*coin_control.m_confirm_target, &feeCalc, ::mempool, conservative_estimate); + CFeeRate feeRate = CFeeRate(CWallet::GetMinimumFee(1000, coin_control, ::mempool, ::feeEstimator, &feeCalc)); - if (feeRate <= CFeeRate(0)) // not enough data => minfee - { - ui->labelSmartFee->setText(BitcoinUnits::formatWithUnit(model->getOptionsModel()->getDisplayUnit(), - std::max(CWallet::fallbackFee.GetFeePerK(), CWallet::GetRequiredFee(1000))) + "/kB"); + ui->labelSmartFee->setText(BitcoinUnits::formatWithUnit(model->getOptionsModel()->getDisplayUnit(), feeRate.GetFeePerK()) + "/kB"); + + if (feeCalc.reason == FeeReason::FALLBACK) { ui->labelSmartFee2->show(); // (Smart fee not initialized yet.
