2017-12-19Remove dead feeest-file read code for old versionsMatt Corallo
0.15.0 introduced a new feeest file format, and support for parsing old versions was never fully added. We now simply fail to read the old format, so remove the dead partial-implementation.

55509f1 Document assumptions that are being made to avoid division by zero (practicalswift) Pull request description: Document assumptions (via `assert(…)`:s) that are being made to avoid division by zero. Rationale: * Make it clear to human reviewers and non-human static analyzers that what might look like potential division by zero cases are written the way they are intentionally (these cases are currently flagged by various static analyzers).

2017-09-11Force explicit double -> int conversion for CFeeRate constructorMatt Corallo
This resolves an issue where estimatesmartfee would return 999 sat/byte instead of 1000, due to floating point loss of precision Thanks to sipa for suggesting is_integral.

Change parameter for conservative estimates to be an estimate_mode string. Change to never return a -1 for failure but to instead omit the feerate and return an error string. Throw JSONRPC error on invalid nblocks parameter.
2017-07-17Merge #10706: Improve wallet fee logic and fix GUI bugsWladimir J. van der Laan

(Alex Morcos) 2fffaa9 Make QT fee displays use GetMinimumFee instead of estimateSmartFee (Alex Morcos) 1983ca6 Use CoinControl to pass custom fee setting from QT. (Alex Morcos) 03ee701 Refactor to use CoinControl in GetMinimumFee and FeeBumper (Alex Morcos) ecd81df Make CoinControl a required argument to CreateTransaction (Alex Morcos) Pull request description: This builds on #10589 (first 5 commits from that PR, last 5 commits are new) The first couple commits refactor to use the CCoinControl class to pass fee calculation parameters around. This allows for fixing the buggy interaction in QT between the global payTxFee which can be modified by the RPC call settxfee or temporarily modified by the QT custom fee settings. Before these changes the GUI could sometimes send a transaction with a recently set payTxFee and not respect the settings displayed in the GUI. After these changes, using the GUI does not involve the global transaction confirm target or payTxFee. The prospective fee displays in the smart fee slider and the coin control dialog are changed to use the fee calculation from GetMinimumFee, this simplifies the code and makes them slightly more correct in edge cases. Maxing the fee calculation with the mempool min fee is move from estimateSmartFee to GetMinimumFee. This fixes a long standing bug, and should be tagged for 0.15 as it is holding up finalizing the estimatesmartfee RPC API before release.

2017-07-14Remove checking of mempool min fee from estimateSmartFee.Alex Morcos
This check has been moved to the wallet logic GetMinimumFee. The rpc call to estimatesmartfee will now no longer return a result maxed with the mempool min fee, but automated fee calculations from the wallet will produce the same result as before and coincontrol and sendcoins dialogs in the GUI will correctly display the right prospective fee. changes to policy/fees.cpp include a big whitespace indentation change.

2017-05-10minor cleanup: remove unnecessary variableAlex Morcos
2017-05-10Introduce a scale factorAlex Morcos
For the per confirmation number tracking of data, introduce a scale factor so that in the longer horizones confirmations are bucketed together at a resolution of the scale. (instead of 1008 individual data points for each fee bucket, have 42 data points each covering 24 different confirmation values.. (1-24), (25-48), etc.. )
2017-05-10Historical block spanAlex Morcos
Store in fee estimate file the block span for which we were tracking estimates, so we know what targets we can successfully evaluate with the data in the file. When restarting use either this historical block span to set valid range of targets until our current span of tracking estimates is just as long.
2017-05-10Clean up fee estimate debug printingAlex Morcos
2017-05-10Track first recorded heightAlex Morcos
Track the first time we seen txs in a block that we have been tracking in our mempool. Used to evaluate validity of fee estimates for different targets.
2017-05-10Rewrite estimateSmartFeeAlex Morcos
Change the logic of estimateSmartFee to check a 60% threshold at half the target, a 85% threshold at the target and a 95% threshold at double the target. Always check the shortest time horizon possible and ensure that estimates are monotonically decreasing. Add a conservative mode, which makes sure that the 95% threshold is also met at longer time horizons as well.
2017-05-10Track failures in fee estimation.Alex Morcos
Start tracking transactions which fail to confirm within the target and are then evicted or otherwise leave mempool. Fix slight error in unit test.
2017-05-10Expose estimaterawfeeAlex Morcos
Track information the ranges of fee rates that were used to calculate the fee estimates (the last range of fee rates in which the data points met the threshold and the first to fail) and provide an RPC call to return this information.

2017-05-10Make EstimateMedianVal smarter about small failures.Alex Morcos
Instead of stopping if it encounters a "sufficient" number of transactions which don't meet the threshold for being confirmed within the target, it keeps looking to add more transactions to see if there is a temporary blip in the data. This allows a smaller number of required data points.
2017-05-10Refactor to update moving average on flyAlex Morcos
2017-05-10Change parameters for fee estimation and estimates on all 3 time horizons.Alex Morcos
Make feerate buckets smaller (5% instead of 10%) and make the 3 different horizons have half lifes of 3 hours, 1 day and 1 week respectively.
