2021-10-22Fix bnb_search_test to use set equivalence forAndrew Chow
For BnB, we only want to check that sets are equivalent with their values, whereas in knapsack we care about the outpoints.

2021-10-15tests: Use Descriptor wallets for generic wallet testsAndrew Chow
For the generic wallet tests, make DescriptorScriptPubKeyMans. There are still some wallet tests that test legacy wallet things. Those remain unchanged.
2021-10-15tests: Use legacy change type in subtract fee from outputs testAndrew Chow
The subtract fee from outputs assumes that the leftover input amount will be dropped to fees. However this only happens if that amount is less than the cost of change. In the event that it is higher than the cost of change, the leftover amount will actually become a change output. To avoid this scenario, force a change type which has a high cost of change.

To avoid issues with test data leaking across tests cases, the global vCoins and testWallet are removed from coinselector_tests and all of the relevant functions reworked to not need them.

2021-10-05refactor: Block unsafe fs::path std::string conversion callsRussell Yanofsky
There is no change in behavior. This just helps prepare for the transition from boost::filesystem to std::filesystem by avoiding calls to methods which will be unsafe after the transaction to std::filesystem to due lack of a boost::filesystem::path::imbue equivalent and inability to set a predictable locale.

2021-09-01refactor: Detach wallet transaction methods (followup for move-only)Russell Yanofsky
Followup to commit "MOVEONLY: CWallet transaction code out of wallet.cpp/.h" that detaches and renames some CWalletTx methods, making into them into standalone functions or CWallet methods instead. There are no changes in behavior and no code changes that aren't purely mechanical. It just gives spend and receive functions more consistent names and removes the circular dependencies added by the earlier MOVEONLY commit. There are also no comment or documentation changes. Removed comments from transaction.h are just migrated to spend.h, receive.h, and wallet.h.

This metric is used as part of bounding the search tree, but it can be generalized to all coin selection solutions, including those with change. As such, this PR introduces the waste metric at a higher level so that we can run both of our coin selection algorithms (BnB and KnapsackSolver) and choose the one which has the least waste. In the event that both find a solution with the same change, we choose the one that spends more inputs. Also this PR sets the long term feerate to 10 sat/vb rather than using the 1008 block estimate. This allows the long term feerate to be the feerate that we switch between consolidating and optimizing for fees. This also removes a bug where the long term feerate would incorrectly be set to the fallback fee. While this doesn't matter prior to this PR, it does have an effect following this. The long term feerate can be configured by the user through a new `-consolidatefeerate` option.

2021-05-19Roll static tx fees into nValueToSelect instead of having it be separateAndrew Chow
The fees for transaction overhead and recipient outputs are now included in nTargetValue instead of being a separate parameter. For the coin selection algorithms, it doesn't matter that these are separate as in either case, the algorithm needs to select enough to cover these fees. Note that setting nValueToSelect is changed as it now includes not_input_fees. Without the change to how nValueToSelect is increased for KnapsackSolver, this would result in overpaying fees. The change to increase by the difference between nFeeRet and not_input_fees allows this to have the same behavior as previously. Additionally, because we assume that KnapsackSolver will always find a solution that requires change (we assume that BnB always finds a non-change solution), we also include the fee for the change output in KnapsackSolver's target. As part of this, we also use the changeless nFeeRet when iterating for KnapsackSolver. This is because we include the change fee when doing KnapsackSolver, so nFeeRet on further iterations won't include the change fee.
