it was pointed out by a few reviewers that the code block at the end
of attempt selection was difficult to follow and lacked comments.
refactor to get rid of triple nested if statement and improve
readibility.
switch to new methods, remove old code. this also
updates the Size, All, and Clear methods to now use
the coins map.
this commit is not strictly a refactor because previously
coin selection was never run over the UNKNOWN type until the last
step when being run over all. now that we are iterating over each,
it is run over UNKNOWN but this is expected to be empty most of the time.

1f798fe85b wallet: Cache SigningProviders (Andrew Chow)
8a105ecd1a wallet: Use CalculateMaximumSignedInputSize to indicate solvability (Andrew Chow)
Pull request description:
While running my coin selection simulations, I noticed that towards the end of the simulation, the wallet would become slow to make new transactions. The wallet generally performs much more slowly when there are a large number of transactions and/or a large number of keys. The improvements here are focused on wallets with a large number of transactions as that is what the simulations produce.
Most of the slowdown I observed was due to `DescriptorScriptPubKeyMan::GetSigningProvider` re-deriving keys every time it is called. To avoid this, it will now cache the `SigningProvider` produced so that repeatedly fetching the `SigningProvider` for the same script will not result in the same key being derived over and over. This has a side effect of making the function non-const, which makes a lot of other functions non-const as well. This helps with wallets with lots of address reuse (as my coin selection simulations are), but not if addresses are not reused as keys will end up needing to be derived the first time `GetSigningProvider` is called for a script.
The `GetSigningProvider` problem was also exacerbated by unnecessarily fetching a `SigningProvider` for the same script multiple times. A `SigningProvider` is retrieved to be used inside of `IsSolvable`. A few lines later, we use `GetTxSpendSize` which fetches a `SigningProvider` and then calls `CalculateMaximumSignedInputSize`. We can avoid a second call to `GetSigningProvider` by using `CalculateMaximumSignedInputSize` directly with the `SigningProvider` already retrieved for `IsSolvable`.
There is an additional slowdown where `ProduceSignature` with a dummy signer is called twice for each output. The first time is `IsSolvable` checks that `ProduceSignature` succeeds, thereby informing whether we have solving data. The second is `CalculateMaximumSignedInputSize` which returns -1 if `ProduceSignature` fails, and returns the input size otherwise. We can reduce this to one call of `ProduceSignature` by using `CalculateMaximumSignedInputSize`'s result to set `solvable`.
Lastly, a lot of time is spent looking in `mapWallet` and `mapTxSpends` to determine whether an output is already spent. The performance of these lookups is slightly improved by changing those maps to use `std::unordered_map` and `std::unordered_multimap` respectively.

701a64f548 test: add support for Decimal to assert_approx (Karl-Johan Alm)
Pull request description:
(note: this was originally titled "add analyzerawtransaction RPC")
This command iterates over the inputs and outputs of the given transactions, and tallies up the balance change for the given wallet. This can be useful e.g. when verifying that a coin join like transaction doesn't contain unexpected inputs that the wallet will then sign for unintentionally.
I originally proposed this to Elements (https://github.com/ElementsProject/elements/pull/1016) and it was suggested that I propose this upstream.
There is an alternative #22776 to instead add this info to `getbalances` when providing an optional transaction as argument.

This command iterates over the inputs and outputs of the given transactions, and tallies up the balance change for the given wallet. This can be useful e.g. when verifying that a coin join like transaction doesn't contain unexpected inputs that the wallet will then sign for unintentionally.
For some reason, the primary consumer of getWalletTxs requires the
transactions to be in hash order when it is processing them. std::map
will iterate in hash order so the transactions end up in that order when
placed into the vector. To ensure this order when mapWallet is no longer
ordered, the vector is replaced with a set which will maintain the hash
order.
In order to avoid constantly re-deriving the same keys in
DescriptorScriptPubKeyMan, cache the SigningProviders generated inside
of GetSigningProvider.
Rename `BResult` class to `util::Result` and update the class interface to be
more compatible with `std::optional` and with a full-featured result class
implemented in https://github.com/bitcoin/bitcoin/pull/25665. Motivation for
this change is to update existing `BResult` usages now so they don't have to
change later when more features are added in #25665.
This change makes the following improvements originally implemented in #25665:
- More explicit API. Drops potentially misleading `BResult` constructor that
treats any bilingual string argument as an error. Adds `util::Error`
constructor so it is never ambiguous when a result is being assigned an error
or non-error value.
- Better type compatibility. Supports `util::Result<bilingual_str>` return
values to hold translated messages which are not errors.
- More standard and consistent API. `util::Result` supports most of the same
operators and methods as `std::optional`. `BResult` had a less familiar
interface with `HasRes`/`GetObj`/`ReleaseObj` methods. The Result/Res/Obj
naming was also not internally consistent.
- Better code organization. Puts `src/util/` code in the `util::` namespace so
naming reflects code organization and it is obvious where the class is coming
from. Drops "B" from name because it is undocumented what it stands for
(bilingual?)
- Has unit tests.

9e04cfaa76 test: add coverage for wallet inconsistent state during sync (furszy)
77de5c693f wallet: guard and alert about a wallet invalid state during chain sync (furszy)
Pull request description:
Follow-up work to my comment in #25239.
Guarding and alerting the user about a wallet invalid state during chain synchronization.
#### Explanation
if the `AddToWallet` tx write fails, the method returns a wtx `nullptr` without removing the recently added transaction from the wallet's map.
Which makes that `AddToWalletIfInvolvingMe` return false (even when the tx is on the wallet's map already), --> which makes `SyncTransaction` skip the `MarkInputsDirty` call --> which leads to a wallet invalid state where the inputs of this new transaction are not marked dirty, while the transaction that spends them still exist on the in-memory wallet tx map.
Plus, as we only store the arriving transaction inside `AddToWalletIfInvolvingMe` when we synchronize/scan block/s from the chain and nowhere else, it makes sense to treat the transaction db write error as a runtime error to notify the user about the problem. Otherwise, the user will lose all the not stored transactions after a wallet shutdown (without be able to recover them automatically on the next startup because the chain sync would be above the block where the txs arrived).
Note:
On purpose, the first commit adds test coverage for it. Showing how the wallet can end up in an invalid state. The second commit corrects it with the proposed solution.

Pull request description:
The GUI currently opts in to RBF by default, but RPCs do not, and `-walletrbf` is default disabled. This PR makes the default in those two places to also opt in.
The last time this was proposed (#9527), the primary objections were the novelty at the time, the inability to bump transactions, and the gui not having the option to disable rbf. In the 5 years since, RBF usage has steadily grown, with ~27% of txs opting in. The GUI has the option to enable/disable RBF, and is also defaulted to having it enabled. And we have the ability to bump RBF'd transactions in both the RPC and the GUI. So I think it makes sense to finally change the default to always opt in to RBF.

In AvailableCoins, we need to know whether we can solve for an output.
This was done by using IsSolvable, which just calls ProduceSignature and
produces a dummy signature. However, we already do that in order to get
the size of the input by using CalculateMaximumSignedInputSize. As this
function returns -1 if ProduceSignature fails, we can just remove the
use of IsSolvable and check that input_bytes is not -1 to determine
the solvability of an output.

Pull request description:
# Concept
Following https://github.com/bitcoin/bitcoin/pull/23789, Bitcoin Core wallet will now generate a change address that matches the payment address type. This improves privacy by not revealing which of the outputs is the change at the time of the transaction in scenarios where the input address types differ from the payment address type. However, information about the change can be leaked in a later transaction. This proposal attempts to address that concern.
## Leaking information in a later transaction
Consider the following scenario:
1. Alice has a wallet with bech32 type UTXOs and pays Bob, who gives her a P2SH address
2. Alice's wallet generates a P2SH change output, preserving her privacy in `txid: a`
3. Alice then pays Carol, who gives her a bech32 address
4. Alice's wallet combines the P2SH UTXO with a bech32 UTXO and `txid: b` has two bech32 outputs
From a chain analysis perspective, it is reasonable to infer that the P2SH input in `txid: b` was the change from `txid: a`. To avoid leaking information in this scenario, Alice's wallet should avoid picking the P2SH output and instead fund the transaction with only bech32 Outputs. If the payment to Carol can be funded with just the P2SH output, it should be preferred over the bech32 outputs as this will convert the P2SH UTXO to bech32 UTXOs via the payment and change outputs of the new transaction.
**TLDR;** Avoid mixing output types, spend non-default `OutputTypes` when it is economical to do so.
# Approach
`AvailableCoins` now populates a struct, which makes it easier to access coins by `OutputType`. Coin selection tries to find a funding solution by each output type and chooses the most economical by waste metric. If a solution can't be found without mixing, coin selection runs over the entire wallet, allowing mixing, which is the same as the current behavior.
I've also added a functional test (`test/functional/wallet_avoid_mixing_output_types.py`) and unit test (`src/wallet/test/availablecoins_tests.cpp`.

fa23c19750 univalue: Avoid narrowing and verbose int constructors (MacroFake)
fa3a9a1e8d rpc: Select int-UniValue constructor for enum value in upgradewallet RPC (MacroFake)
Pull request description:
As UniValue provides several constructors for integral types, the
compiler is unable to select one if the passed type does not exactly
match. This is unintuitive for developers and forces them to write
verbose and brittle code. (Refer to `-Wnarrowing` compiler warning)
For example, there are many places where an unsigned int is cast to a
signed int. While the cast is safe in practice, it is still needlessly
verbose and confusing as the value can never be negative. In fact it
might even be unsafe if the unsigned value is large enough to map to a
negative signed one.
Fix this issue and other (minor) type issues.

Run coin selection on each OutputType separately, choosing the best
solution according to the waste metric.
This is to avoid mixing UTXOs that are of different OutputTypes,
which can hurt privacy.
If no single OutputType can fund the transaction, then coin selection
considers the entire wallet, potentially mixing (current behavior).
This is done inside AttemptSelection so that all OutputTypes are
considered at each back-off in coin selection.
Pass the whole CoinsResult struct to SelectCoins instead of only a
vector. This means we now have to remove preselected coins from each
OutputType vector and shuffle each vector individually.
Pass the whole CoinsResult struct to AttemptSelection. This involves
moving the logic in AttemptSelection to a newly named function,
ChooseSelectionResult. This will allow us to run ChooseSelectionResult
over each OutputType in a later commit. This ensures the backoffs work
properly.
Update unit and bench tests to use CoinResult.

817326a828 wallet: avoid rescans if under the snapshot (James O'Beirne)
Pull request description:
This is part of the [assumeutxo project](https://github.com/bitcoin/bitcoin/projects/11) (parent PR: #15606)
---
Refuse to load a wallet if it requires a rescan lower than the height of assumed-valid blocks.
Of course in live code right now, `BLOCK_ASSUMED_VALID` block index entries don't exist since they're a unique flag introduced by the use of UTXO snapshots, so this is prophylactic code exercised only by unittests.

Code review ACK 817326a828. This seems like the simplest change we can make to avoid wallet problems when an assumeutxo snapshot is loaded.

Add new interfaces::BlockInfo struct to be able to pass extra block
information (file and undo information) to indexes which they are
updated to use high level interfaces::Chain notifications.
This commit does not change behavior in any way.

Pull request description:
This PR picks up the work from #18964 and closes#18954.
It should incorporate all the unaddressed feedback from the PR:
- Mempool rescan now expanded to all relevant import* RPCs
- Added documentation in the help of each RPC
- More tests

When a transaction arrives, the wallet mark its inputs (prev-txs) as dirty.
Clearing the wallet transaction cache, triggering a balance recalculation.
If this does not happen due a db write error during `AddToWallet`, the wallet
will be in an invalid state: The transaction that spends certain wallet UTXO will
exist inside the in-memory wallet tx map, having the credit/debit calculated,
while its inputs will still have the old cached data (like if them were never
spent).
-Context:
If `AddToWallet` db write fails, the method returns a wtx nullptr without
removing the recently added transaction from the wallet's map.
-Problem:
When a db write error occurs, `AddToWalletIfInvolvingMe` return false even
when the tx is on the wallet's map already --> which makes `SyncTransaction`
skip the `MarkInputsDirty` call --> which leads to a wallet invalid state
where the inputs of this new transaction are not marked dirty, while the
transaction that spends them still exist on the in-memory wallet tx map.
Plus, as we only store arriving transaction inside `AddToWalletIfInvolvingMe`
when we synchronize/scan blocks from the chain and nowhere else, it makes sense
to treat the tx db write error as a runtime error to notify the user about the
problem. Otherwise, the user will lose all the not stored transactions after a
wallet shutdown (without be able to recover them automatically on the next
startup because the chain sync would be above the block where the txs arrived).
757216e31c wallet: don't iter twice when getting the cached debit/credit amount (Antoine Poinsot)
Pull request description:
A small optimization i stumbled upon while looking at something else. Figured it could be worth a PR.
Instead of calling GetCachableAmount twice, which will result in
iterating through all the transaction txins/txouts and calling
GetDebit/GetCredit (which lock cs_wallet), just merge the filters and do
it once.

fa277cd55d univalue: Throw exception on invalid pushes over silent ignore (MacroFake)
ccccc17b91 refactor: Default options in walletcreatefundedpsbt to VOBJ instead of VNULL (MacroFake)
Pull request description:
The return value of the `push*` helpers is never used, but important to determine if the operation was successful. One way to fix this would be to add the "nodiscard" attribute. However, this would make the code (and this diff) overly verbose for no reason.
So fix it by removing the never used return value. Also, fail verbosely in case of a programming mistake.

UniValue does not have a constructor for enum values, however the
compiler will decay the enum into an int and select that constructor.
Avoid this compiler magic and clarify the code by explicitly selecting
the int-constructor.
This is needed for the next commit.
fa475e9c79 refactor: Return BResult from restoreWallet (MacroFake)
fa8de09edc Prepare BResult for non-copyable types (MacroFake)
Pull request description:
This avoids the `error` in-out param (and if `warnings` is added to `BResult`, it will avoid passing that in-out param as well).
Also, as it is needed for this change, prepare `BResult` for non-copyable types.
