38516f9078497d3e8456d48300eca40c35a281f2 Fix input size assertion in wallet_bumpfee.py (Gregory Sanders)
Pull request description:
I was investigating a curious error for https://github.com/bitcoin/bitcoin/pull/17290 and realized that this check should have caught that error earlier in the test.
The loop is intended to ensure that only a single input exists the entire time until the change output disappears, a single additional bump occurs, then it leaves the loop.

The use of native segwit addresses (pure p2wpkh instead of p2sh-p2wpkh) leads
to smaller transaction sizes, needing adaption of some constants in the
following test cases:
- test_dust_to_fee(): adaption of dust calculation
(p2wpkh spend estimate of 67 is taken from src/policy/policy.cpp:GetDustThreshold())
- test_maxtxfee_fails(): lowering -maxtxfee setting to trigger fail

Pull request description:
Taking over for https://github.com/bitcoin/bitcoin/pull/16492 which seems to have gone inactive.
Only minor commit cleanups, rebase, and some help text fixes on top of previous PR. Renamed `feeRate` to `fee_rate` to reflect updated guidelines.

Unnamed arguments are confusing as to what they mean without looking up
the function signature.
Since segwit is active by default in regtest, and all blocks are
serialized with witness (#15664, c459c5f), remove the argument
`with_witness=True` from all calls to `CBlock::serialize` and
`BlockTransactions::serialize`.
This diff has been created with a script, but is better reviewed without
a scripted diff.
sed -i --regexp-extended -e 's/block(_?[2a-z]*)\.serialize\([a-z_]*=?True/block\1.serialize(/g' $(git grep -l serialize ./test)

184f8785f wallet_bumpfee.py: add test for change key preservation (Gregory Sanders)
d08becff8 add functional tests for feerate bumpfee with adding inputs (Gregory Sanders)
0ea47ba7b generalize bumpfee to add inputs when needed (Gregory Sanders)
Pull request description:
When targeting a feerate using `bumpfee`, call a new function that directly uses `CWallet::CreateTransaction` and coin control to get the desired result. This allows us to get a superset of previous behavior, with an arbitrary RBF bump of a transaction provided it passes the preconditional checks and spare confirmed utxos are available.
Note(s):
0) The coin selection will use knapsack solver for the residual selection.
1) This functionality, just like knapsack coin selection in general, will hoover up negative-value inputs when given the chance.
2) Newly added inputs must be confirmed due to current Core policy. See error: `replacement-adds-unconfirmed`
3) Supporting this with `totalFee` is difficult since the "minimum total fee" option in `CreateTransaction` logic was (rightly)taken out in #10390 .

a769461d5e37ddcb771ae836254fdc69177a28c4 Move BerkeleyEnvironment deletion from internal method to callsite (Andrew Chow)
Pull request description:
This is the replacement for #11678 which implements @ryanofsky's [suggestion](https://github.com/bitcoin/bitcoin/pull/11678#pullrequestreview-76464511).
Shutting down the software was to prevent the BDB environment from writing unencrypted private keys to disk in the database log files, as was noted [here](https://bitcointalk.org/index.php?topic=51474.msg616068#msg616068). This PR replaces the shutdown behavior with a CDBEnv flush, close, and reopen which achieves the same effect: everything is cleanly flushed and closed, the log files are removed, and then the environment reopened to continue normal operation.
To ensure that no unencrypted private keys are in the log files after encrypting the wallet, I wrote [this script](https://gist.github.com/achow101/7f7143e6c3d3fdc034d3470e72823e9d) to pull private keys from the original wallet file and searches for these keys in the log files (note that you will have to change your file paths to make it work on your own machine).
As for concerns about private keys being written to slack space or being kept in memory, these behaviors no longer exist after the original wallet encryption PR and the shutting down solution from 2011.

Since the database environment is flushed, closed, and reopened during
EncryptWallet, there is no need to shut down the software anymore.

f526046 adapt bumpfee change discard test to be more strict and add note on p2sh discrep (Gregory Sanders)
5805d6f feebumper: discard change outputs below discard rate (Gregory Sanders)
Pull request description:
The "discard rate" is the concept we use to ensure the wallet isnt creating not so useful just-above-relay dust.
Outside of bumpfee previous to this PR, and manually creating such an output, the wallet will never make change outputs of that size, preferring to send them to fees instead.
"Worst case" for the user is that users pay a slightly higher feerate than they were expecting, which is already a possibility with relay dust.
