Merge #17568: wallet: fix when sufficient preset inputs and subtractFeeFromOutputs
eadd1304c8 tests: Add a test for funding with sufficient preset inputs and subtractFeeFromOutputs (Andrew Chow)
ff330badd4 Default to bnb_used = false as there are many cases where BnB is not used (Andrew Chow)

Pull request description:

  #17290 introduced a bug where, when we had preset inputs that covered the amount being sent and subtractFeeFrromOutputs was being used, transaction funding would result in a `Fee exceeds maximum configured by -maxtxfee` error. This was happening because we weren't setting `bnb_used = false` when the preset inputs were used as it should have been. This resulted in a too high fee because the change would go to fees accidentally.

  Apparently this particular case doesn't have a test, so I've added one as well.

    ACK eadd130. I can't get this new test to fail on macOS (without this PR). It passes whether or not I compile with `--enable-debug`. It does fail on Ubuntu. Yay undefined behavior... Anyway, it's a useful test.

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.

Merge #17435: test: check custom ancestor limit in mempool_packages.py
49997813a4 test: check custom ancestor limit in mempool_packages.py (Sebastian Falbesoner)

Pull request description:

  The functional test `mempool_packages.py` starts one node with default ancestor/descendant limit settings and one with a custom, reduced ancestor limit (currently `-limitancestorcount=5`). The effect of the latter had not been tested yet though. This is approached in this PR by checking on the expected mempool contents of node1 after the node0 ancestor tests are done, via the following three conditions:
  - the # of txs in the node1 mempool is equal to the the limit
  - all txs in node1 mempool are a subset of txs in node0 mempool
  - the node1 mempool txs match the start of the constructed tx-chain

  Note that this still doesn't *fully* check the expected mempool of node1 (e.g. that it isn't influenced by `prioritisetransaction` RPC on node0), hence I add another TODO. In the future it would make sense to also set a custom descendant limit when the second TODO about checking node1's mempool is approached: 89e93135ae/test/functional/mempool_packages.py (L228)

Pull request description:

  Speed up rpc_fundrawtransaction.py

  Most of the time in rpc_fundrawtransaction.py is spent waiting for
  unconfirmed transactions to propagate. Net processing adds a poisson
  random delay to the time it will INV transactions with a mean interval
  of 5 seconds. Calls like the following:

  ```
  self.nodes[2].sendrawtransaction(signedTx['hex'])
  self.sync_all()
  self.nodes[1].generate(1)
  ````

  will therefore introduce a delay waiting for the mempools to sync.
  Instead just generate the block on the node that sent the transaction:

  ```
  self.nodes[2].sendrawtransaction(signedTx['hex'])
  self.nodes[2].generate(1)
  ```

  rpc_fundrawtransaction.py is not intended to be a test for transaction
  relay, so it's ok to do this.

  Issue: #15605
  Specification: https://github.com/jamesob/assumeutxo-docs/tree/master/proposal

  ---

  This changeset defines the serialization format for UTXO snapshots and adds an RPC command for creating them, `dumptxoutset`. It also adds a convenience script for generating and verifying snapshots at a certain height, since that requires doing a hacky rewind of the chain via `invalidateblock`.

  All of this is unused at the moment.

Pull request description:

  This slightly modifies the behavior of IsTrusted to recursively check the parents of a transaction. Otherwise, it's possible that a parent is not IsTrusted but a child is. If a parent is not trusted, then a child should not be either.

  This recursive scan can be a little expensive, so ~it might be beneficial to have a way of caching IsTrusted state, but this is a little complex because various conditions can change between calls to IsTrusted (e.g., re-org).~ I added a cache which works per call/across calls, but does not store the results semi-permanently. Which reduces DoS risk of this change. There is no risk of untrusted parents causing a resource exploitation, as we immediately return once that is detected.

  This is a change that came up as a bug-fix esque change while working on OP_SECURETHEBAG. You can see the branch where this change is important here: https://github.com/bitcoin/bitcoin/compare/master...JeremyRubin:stb-with-rpc?expand=1. Essentially, without this change, we can be tricked into accepting an OP_SECURETHEBAG output because we don't properly check the parents. As this was a change which, on its own, was not dependent on OP_SECURETHEBAG, I broke it out as I felt the change stands on its own by fixing a long standing wallet bug.

  The test wallet_balance.py has been corrected to meet the new behavior. The below comment, reproduced, explains what the issue is and the edge cases that can arise before this change.

          # Before `test_balance()`, we have had two nodes with a balance of 50
          # each and then we:
          #
          # 1) Sent 40 from node A to node B with fee 0.01
          # 2) Sent 60 from node B to node A with fee 0.01
          #
          # Then we check the balances:
          #
          # 1) As is
          # 2) With transaction 2 from above with 2x the fee
          #
          # Prior to #16766, in this situation, the node would immediately report
          # a balance of 30 on node B as unconfirmed and trusted.
          #
          # After #16766, we show that balance as unconfirmed.
          #
          # The balance is indeed "trusted" and "confirmed" insofar as removing
          # the mempool transactions would return at least that much money. But
          # the algorithm after #16766 marks it as unconfirmed because the 'taint'
          # tracking of transaction trust for summing balances doesn't consider
          # which inputs belong to a user. In this case, the change output in
          # question could be "destroyed" by replace the 1st transaction above.
          #
          # The post #16766 behavior is correct; we shouldn't be treating those
          # funds as confirmed. If you want to rely on that specific UTXO existing
          # which has given you that balance, you cannot, as a third party
          # spending the other input would destroy that unconfirmed.
          #
          # For example, if the test transactions were:
          #
          # 1) Sent 40 from node A to node B with fee 0.01
          # 2) Sent 10 from node B to node A with fee 0.01
          #
          # Then our node would report a confirmed balance of 40 + 50 - 10 = 80
          # BTC, which is more than would be available if transaction 1 were
          # replaced.

  The release notes have been updated to note the new behavior.
