10d91c5abe wallet: Deduplicate Resend and ReacceptWalletTransactions
Both of these functions do almost the exact same thing. They can be
deduplicated so that their behavior matches except for the filtering
aspect. As this function will now always be called on wallet loading,
nNextResend will also always be initialized, so
wallet_resendwallettransactions.py is updated to account for that.

This also resolves a bug where ResendWalletTransactions would fail to
rebroadcast txs in insertion order thereby potentially rebroadcasting a
child transaction before its parent and causing the child to not
actually get rebroadcast.

Also names the combined function to ResubmitWalletTransactions as the
function just submits the transactions to the mempool rather than doing
any sending by itself.

5ef8c2c9fc test: fix typo for MaybeResendWalletTxs (stickies-v)
fbba4a1316 wallet: trigger MaybeResendWalletTxs() every minute (stickies-v)

Pull request description:

  ResendWalletTransactions() only executes every [12-36h (24h average)](1420547ec3/src/wallet/wallet.cpp (L1947)). Triggering it every second is excessive, once per minute should be plenty.

  The goal of this PR is to reduce the amount of (unnecessary) schedule executions by ~60x without meaningfully altering transaction rebroadcast logic/assumptions which would require more significant review.

Merge bitcoin/bitcoin#25896: wallet: Log when Wallet::SetMinVersion sets a different minversion
835bd27e9a Wallet::SetMinVersion - Log the new minversion (Ali Sherief)

Pull request description:

  This change prints a single additional line in the debug.log when bitcoin-cli loads a wallet using `loadwallet` (*not* `createwallet`).

  When Bitcoin Core creates a wallet, it's `minversion` is set to `FEATURE_BASE`, which is 10500. However, once the wallet is unloaded using `unloadwallet` or through program termination, and subsequently loaded again, `loadwallet` updates the `minversion` in the wallet.dat file to `FEATURE_LATEST`, currently 169900.

  The current logging format prints the very old wallet version during `createwallet`, and then the actual version in calls to `loadwallet`. This has confused at least one person ([reference](https://bitcointalk.org/index.php?topic=5410650.0) - I was the one who asked there if there were plans to change that behavior, and was subsequently redirected here by achow), so it will be very helpful to users to explicitly specify in the logs what the walletdb is doing.

Pull request description:

  Benefits:
  1. more accurate waste calculation for knapsack. Waste calculation is now consistent with tx building code. Before we always assumed change for knapsack even when the solution is changeless4.
  2. simpler tx building code. Only create change output when it's needed
  3. makes it easier to correctly account for fees for CPFP inputs (should be done in a follow up)

  In the first three commits we fix the code to accurately track selection target in `SelectionResult::m_target`
  Then we introduce new variable `min_change` that represents the minimum viable change amount
  Then we introduce `SelectionResult::GetChange()` which incapsulates dropping change for fee logic and uses correct values of `SelectionResult::m_target`
  Then we use `SelectionResult::GetChange()` in both tx building and waste calculation code

  This PR is a refactoring and shouldn't change the behaviour.
  There is only one known small change (arguably a bug fix). Before we dropped change output if it's smaller than `cost_of_change` after paying change fees. This is incorrect as `cost_of_change` already includes `change_fee`.

Merge bitcoin/bitcoin#25775: docs: remove non-signaling mentions of BIP125
1dc03dda05 [doc] remove non-signaling mentions of BIP125 (glozow)
32024d40f0 scripted-diff: remove mention of BIP125 from non-signaling var names (glozow)

Pull request description:

  We have pretty thorough documentation of our RBF policy in doc/policy/mempool-replacements.md. It enumerates each rule with several sentences of rationale. Also, each rule pretty much has its own function (3 and 4 share one), with extensive comments. The doc states explicitly that our rules are similar but differ from BIP125, and contains a record of historical changes to RBF policy.

  We should not use "BIP125" as synonymous with our RBF policy because:
  - Our RBF policy is different from what is specified in BIP125, for example:
      - the BIP does not mention our rule about the replacement feerate being higher (our Rule 6)
      - the BIP uses minimum relay feerate for Rule 4, while we have used incremental relay feerate since #9380
      - the "inherited signaling" question (CVE-2021-31876). Call it discrepancy, ambiguous wording, doc misinterpretation, or implementation details, I would recommend users refer to doc/policy/mempool-replacements.md
      - the signaling policy is configurable, see #25353
  - Our RBF policy may change further
  - We have already marked BIP125 as only "partially implemented" in docs/bips.md since 1fd49eb498
  - See comments from people who are not me recently:
      - https://github.com/bitcoin/bitcoin/pull/25038#discussion_r909507429
      - https://github.com/bitcoin/bitcoin/pull/25575#issuecomment-1179519204

  This PR removes all non-signaling mentions of BIP125 (if people feel strongly, we can remove all mentions of BIP125 period). It may be useful to refer to the concept of "tx opts in to RBF if it has at least one nSequence less than (0xffffffff - 1)" as "BIP125 signaling" because:
  - It is succint.
  - It has already been widely marketed as BIP125 opt-in signaling.
  - Our API uses it when referring to signaling (e.g. getmempoolentry["bip125-replaceable"] and wallet error message "not BIP 125 replaceable"). Changing those is more invasive.
  - If/when we have other ways to signal in the future, we can disambiguate them this way. See #25038 which proposes another way of signaling, and where I pulled these commits from.

  Alternatives:
  - Changing our policy to match BIP125. This doesn't make sense as, for example, we would have to remove the requirement that a replacement tx has a higher feerate (Rule 6).
  - Changing BIP125 to match what we have. This doesn't make sense as it would be a significant change to a BIP years after it was finalized and already used as a spec to implement RBF in other places.
  - Document our policy as a new BIP and give it a number. This might make sense if we don't expect things to change a lot, and can be done as a next step.

612f1e44fe bumpfee: Calculate fee by looking up UTXOs (Andrew Chow)

Pull request description:

  This PR allows `psbtbumpfee` to return a PSBT for transactions that contain external inputs. This does not work for bumping in the GUI nor `bumpfee` because these need private keys available to sign and send the transaction. But `psbtbumpfee` returns a psbt, so it is fine to not be able to sign.

  In order to correctly estimate the size of the inputs for coin selection, the fee bumper will use the size of the inputs of the transaction being bumped. Because the sizes of signatures are not guaranteed, for external inputs, the fee bumper will verify the scripts with a special SignatureChecker which will compute the weight of all of the signatures in that input, and compute their weights if those signatures were maximally sized. This allows the fee bumper to obtain a max size estimate for each external input.

  Builds on #23201 as it relies on the ability to pass weights in to coin selection.

  Closes #23189

a0c3afb898 bumpfee: extract weights of external inputs when bumping fee
When bumping the fee of a transaction containing external inputs,
determine the weights of those inputs. Because signatures can have a
variable size, the script is executed with a special SignatureChecker
which will compute the total weight of the signatures in the transaction
and the weight if they were all maximum size signatures. This allows us
to compute the maximum weight of the input for use during coin
selection.

Pull request description:

  if a transaction is being funded that has an external input, and that input's parent is also in the wallet, we will fail to detect that and fail to fund the transaction. In order to correctly detect such inputs, we need to be doing `IsMine` on all specified inputs in order to use `Select` and `SelectExternal` correctly. Additionally `SelectCoins` needs to call `CalculateMaximumSignedInputSize` with the correct parameters which depends on whether the wallet is able to solve for the input. Because there are some situations where the wallet could find an external input to belong to it (e.g. watching an address - unable to solve, but will be ISMINE_WATCHONLY), instead of switching which `CalculateMaximumSignedInputSize` to use, we should call the one that uses the wallet, and if that fails, try again with the one that uses external solving data.

  Also adds a test for this case.

Merge bitcoin/bitcoin#25077: Fix chain tip data race and corrupt rest response
fac04cb6ba refactor: Add lock annotations to Active* methods (MacroFake)
fac15ff673 Fix logical race in rest_getutxos (MacroFake)
fa97a528d6 Fix UB/data-race in RPCNotifyBlockChange (MacroFake)
fa530bcb9c Add ChainstateManager::GetMutex(), an alias for ::cs_main (MacroFake)

Pull request description:

  This fixes two issues:

  * A data race in `ActiveChain`, which returns a reference to the chain (a `std::vector`), which is not thread safe. See also below traceback.
  * A corrupt rest response, which returns a blockheight and blockhash, which are unrelated to each other and to the result, as the chain might advance between each call without cs_main held.

  The issues are fixed by taking cs_main and holding it for the required time.

  ```

Pull request description:

  This PR is to address follow-ups for #24584, specifically:

  * Remove redundant, hard-to-read code by adding a new `OutputType` and adding shuffle, erase, and push_back methods for `CoinsResult`
  * Add missing `BOOST_ASSERT` to unit test
  * Ensure functional test only runs if using descriptor wallets
  * Improve readability of `AttemptSelection` by removing triple-nested if statement

  Note for reviewers: commit `refactor: add new helper methods` should throw an "unused function warning"; the function is used in the next commit. Also, commit `wallet: switch to new shuffle, erase, push_back` will fail to compile, but this is fixed in the next commit with a scripted-diff. the commits are separate like this (code change then scripted-diff) to improve legibility.

Pull request description:

  Wallet descriptors are useful for applications using the Bitcoin Core wallet as a backend for tracking coins, as they allow to track coins for multiple descriptors in a single wallet. However there is no information currently given for such applications to link a coin with an imported descriptor, severely limiting the possibilities for such applications of using multiple descriptors in a single wallet. This PR outputs the matching imported descriptor(s) for a given received coin in `listsinceblock` (and friends).

  It comes from a need for an application i'm working on, but i think it's something any software using `bitcoind` to track multiple descriptors in a single wallet would have eventually. For instance i'm thinking about the BDK project. Currently, the way to achieve this is to import raw addresses with labels and to have your application be responsible for wallet things like the gap limit.

  I'll add this to the output of `listunspent` too if this gets a few Concept ACKs.

rpc: add an include_change parameter to listsinceblock
It's useful for an external application tracking coins to not be limited
by our change detection. For instance, for a watchonly wallet with two
descriptors a transaction from one to the other would be considered a
change output and not be included in the result (if the address was not
generated by this wallet).

This is a refactor, putting the burden to think about thread safety to

thread safety where none exists, as is evident in the previous two

by the sum of (effective) values. This causes incorrect m_target value.

Create separate instance of SelectionResult for all the preselected inputs and
set the target equal to the sum of (effective) values. Target for preselected
SelectionResult is equal to the delta for the search target. To get the final
SelectionResult with accurate m_target we merge both SelectionResult instances.

SelectionResult::m_target should be equal to actual selection target.
Selection target is the sum of all recipient amounts plus non input fees.
So we need to remove change_fee from the m_target. It's safe because change
target is always greater than the change fee, so we can always cover fees
if change output is created.

Pull request description:

  If there are multiple external signers, `GetExternalSigner()` will
  just pick the first one in the list. If the user has two or more
  hardware wallets connected at the same time, he might not notice this.

  This PR adds a check and fails with suitable message, forcing the user to disconnect all but one external signer, so that there is no ambiguity as to which external signer was used.

wallet: avoid double TopUp() calls on descriptor wallets
Move TopUp() responsibility from the wallet class to each scriptpubkeyman.
So each spkm can decide to call it or not after perform the basic checks
for the new destination request.

Reason:

We were calling it twice in the following flows for descriptor wallets:

A) CWallet::GetNewDestination:
   1) Calls spk_man->TopUp()
   2) Calls spk_man->GetNewDestination() --> which, after the basic script checks, calls TopUp() again.

B) CWallet::GetReservedDestination:
   1) Calls spk_man->TopUp()
   2) Calls spk_man->GetReservedDestination() --> which calls to GetNewDestination (which calls to TopUp again).

  Now that we have descriptors there is no need to try to sign for a scriptPubKey using dummy signatures, and using a mocked verification of this witness against the interpreter, just to make sure we know how to spend such a Script.

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.

  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.

[doc] remove non-signaling mentions of BIP125
Our RBF policy is different from the rules specified in BIP125. For
example, the BIP does not mention Rule 6, and our Rule 4 uses the
(configurable) incremental relay feerate (distinct from the
minimum relay feerate). Those interested in our policy should refer to
doc/policy/mempool-replacements.md instead. These rules may also
continue to diverge with package RBF and other RBF improvements. Keep
references to the BIP125 signaling wrt sequence numbers, since that is
still correct and widely used. It is helpful to refer to this as "BIP125
signaling" since it is unambiguous and succint, especially if we have
multiple ways to signal replaceability in the future.

The rule numbers in doc/policy/mempool-replacements.md correspond
largely to those of BIP 125, so we can still refer to them like "Rule 5."

a23cca56c0 refactor: Replace BResult with util::Result
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.

61d9149e78 rpc: Default rbf enabled (Andrew Chow)
e3c33637ba wallet: Enable -walletrbf by default (Andrew Chow)

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.

8a105ecd1a wallet: Use CalculateMaximumSignedInputSize to indicate solvability
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.

  # 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:

  ![mix input types(1)](https://user-images.githubusercontent.com/7444140/158597086-788339b0-c698-4b60-bd45-9ede4cd3a483.png)

  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.

Pull request description:

  This was done in the context of https://github.com/bitcoin/bitcoin/pull/25284 , but I think it also makes sense standalone.

  The basic idea is that serialization type should not be initialized when it is not needed. Same for the serialization version.

  So do this here for `HashWriter`. `CHashWriter` remains in places where it is not yet possible.

  Another wallet's code garbage collector work. Part of the `mapWallet` encapsulation goal.

  2) Remove always false `recalculate` argument from `GetCachableAmount`.
  3) Merge `CachedTxGetImmatureCredit` and `CachedTxGetImmatureWatchOnlyCredit` as they do share the exact same code.
  4) Clean `InputIsMine` method; use `GetWalletTx` instead of access the wallet's map directly.
  5) Clean `AllInputsMine` method; use `InputIsMine` instead of duplicate the exact same code internally.
