Pull request description:

  Don't have `cs_wallet` locked while calling each `context.wallet_load_fns`. A load handler can always lock `cs_wallet` if needed.

  The lock was added in 1c7e25db0c to satisfy TSAN. With 44c430ffac most of the code requiring the lock is in `CWallet::AttachChain`. A comment is added to warn about wallets_mutex and cs_wallet lock ordering.

  The "keypoololdest" field in the `getwalletinfo` RPC response should be used for legacy wallets only.

80dc829be7 tests: Calculate fees more similarly to CFeeRate::GetFee (Andrew Chow)
ce2cc44afd tests: Test for assertion when feerate is rounded down (Andrew Chow)
0fbaef9676 fees: Always round up fee calculated from a feerate (Andrew Chow)

Pull request description:

  When calculating the fee for a feerate, it is possible that the final calculation will have fractional satoshis. Currently those are ignored via truncation which results in the absolute fee being rounded down. Rounding down is problematic because it results in a feerate that is slightly lower than the feerate represented by the `CFeeRate` object. A slightly lower feerate particularly causes issues for coin selection as it can trigger an assertion error. To avoid potentially underpaying the feerate (and the assertion), always round up the calculated fee.

  A test is added for the assertion, along with a comment explaining what happens.

  It is unlikely that a user can trigger this as it requires a very specific set of rounding errors to occur as well as the transaction not needing any change and being right on the lower bound of the exact match window. However I was able to trigger the assertion while running coin selection simulations, albeit after thousands of transactions and with some weird feerates.

   * "Leaving block file" moves from validation to blockstorage
   * "write coins cache to disk" to bench

  Also adds the hash of the block to the log message when AcceptBlockHeader is rejecting because of problems with the prev block.

Pull request description:

  Currently `fundrawtransaction` and `walletcreatefundedpsbt` both do not allow external inputs as the wallet does not have the information necessary to estimate their fees.

  This PR adds an additional argument to both those RPCs which allows the user to specify solving data. This way, the wallet can use that solving data to estimate the size of those inputs. The solving data can be public keys, scripts, or descriptors.

07b44f16e7 wallet: fix ComputeTimeSmart algorithm to use blocktime during old block rescanning (BitcoinTsunami)

Pull request description:

  The function ComputeTimeSmart in wallet.cpp assume that transaction are discovered in the right order.
  Moreover the 'smarttime' determination algorithm is coded with realtime scenario in mind and not rescanning of old block.

  The functional test demonstrate that if the user import a wallet, then rescan only recent history, and then rescan the entire history, the older transaction discovered would have an incorrect time determination.
  In the context of rescanning old block, the only time value that as a meaning is the blocktime.

  That's why I've fixed the problem with a simple separation between rescanning of old block and realtime time determination. The fix is written to have no impact on every realtime scenario and only impact the behaviour during a rescanning process.
  This PR Fixes #20181.

  To be fair, I don't think that this bug could be triggered with the wallet GUI, because it always proceed with a proper rescan.
  But RPC API provide the possibility to trigger it. I've discovered it, because Specter desktop v0.10.0 was impacted. (https://github.com/cryptoadvance/specter-desktop/issues/680).

Pull request description:

  This PR is in response to the issue [#19699](https://github.com/bitcoin/bitcoin/issues/19699).

  Based on the discussion in the comments of PR [#22673](https://github.com/bitcoin/bitcoin/pull/22673) changes have been made in the `estimatesmartfee` itself such that it takes into account `mempoolMinFee` and `relayMinFee` . Hence it provides a fee estimate that is most likely to be paid by the user in an actual transaction, preventing issues such as [#16072](https://github.com/bitcoin/bitcoin/issues/16072).

  The test file test/functional/feature_fee_estimation.py has also been updated to check this functionality.

Pull request description:

  Resolves #21797 now that we've branched-off to v23 ("addresses" and "reqSigs" deprecated) "ExtractDestinations" should be removed.

   `-deprecatedrpc=addresses` was initially added in this PR #20286 (which resolved the original issue #20102).

  Some chunks of code and logic are no longer used/necessary with the removal of this, and therefore some minor refactoring is done in this PR as well (separated commits)

efcaefc7b5 test: Add remaining scenarios of 0 waste (rajarshimaitra)

Pull request description:

  As per the [review club](https://bitcoincore.reviews/22009) discussion on #22009 , it was observed that there were other two fee scenarios in which selection waste could be zero.

  These are:
   - (LTF - Fee) == Change Cost
   - (LTF - Fee) == Excess

  Even though these are obvious by the definition of waste metric, adding tests for them can be helpful in explaining its behavior
  to new readers of the code base, along with pinning the behavior for future.

  This PR adds those two cases to waste calculation unit test.

  Also let me know if I am missing more scenarios.

Pull request description:

  This makes `CWallet` and `CWalletTx` methods in `spend.cpp` and `receive.cpp` files into standalone functions.

  It's a followup to [#21207 MOVEONLY: CWallet transaction code out of wallet.cpp/.h](https://github.com/bitcoin/bitcoin/pull/21207), which moved code from `wallet.cpp` to new `spend.cpp` and `receive.cpp` files.

  There are no changes in behavior. This is just making methods into functions and removing circular dependencies created by #21207. There are no comment or documentation changes, either. Removed comments from `transaction.h` are just migrated to `spend.h`, `receive.h`, and `wallet.h`.

Pull request description:

  The places where we need to lookup information for a XOnlyPubKey
  currently implement a hack which makes both serializations of the full
  pubkey in order to try the CKeyIDs for the lookup functions. Instead of
  duplicating this everywhere it is needed, we can consolidate the CKeyID
  generation into a function, and then have wrappers around GetPubKey,
  GetKey, and GetKeyOrigin which takes the XOnlyPubKey, retrieves all of
  the CKeyIDs (using the new GetKeyIDs() function in XOnlyPubKey), and
  tries their respective underlying lookup function.

54de7b4746 Allow the long term feerate to be configured, default of 10 sat/vb (Andrew Chow)

Pull request description:

  Branch and Bound introduced a metric that we call waste. 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.

Pull request description:

  the result of CWallet::IsHDEnabled() was initialized with true.

  But in case of no keys or a blank hd wallet the iterator would be skipped
  and not set to false but true, since the loop would be not entered.

  That had resulted in a wrong return and subsequent false HD and watch-only
  icon display in GUi when reloading a wallet after closing.

  As far as I know, there is no command to restore the wallet from a backup file.
  The only way to do this is to replace the `wallet.dat` of a newly created wallet with the backup file, which is hardly an intuitive way.

  To test:
  First create a backup file:
  `$ bitcoin-cli -rpcwallet="wallet-01" backupwallet /home/Backups/wallet-01.bak`

  Then restore it in another wallet:
  `$ bitcoin-cli  restorewallet "restored-wallet-01" /home/Backups/wallet-01.bak`

Since we know this workaround is imperfect and the goal of this PR is mainly to fix CI errors, I would probably be inclined to limit the workaround to as few places as possible where we have seen actual failures, instead of adding the workaround to as many places as possible, where there is some chance it might trigger new failures. But since this workaround is so straightforward and almost looks like a real fix, probably it doesn't matter.

  > bitcoin-cli -regtest -rpcwallet=old listdescriptors true | jq '.descriptors' > descriptors.txt

  > bitcoin-cli -regtest -named createwallet wallet_name=new descriptors=true blank=true
  > bitcoin-cli -regtest -rpcwallet=new importdescriptors "$(cat descriptors.txt)"

Pull request description:

  Currently fetching a normalized descriptor requires the wallet to be unlocked as it needs the private keys to derive the last hardened xpub. This is not very user friendly as normalized descriptors shouldn't require and don't involve the private keys except for derivation. We solve this problem by caching the last hardened xpub (which has to be derived at some point when generating the address pool).

  However the last hardened xpub was not already being cached. We only cached the immediate parent xpub and derived child keys. For example, with a descriptor derivation path of `/84'/0'/0'/0/*`, the parent xpub that is cached is `m/84'/0'/0'/0`, and the child keys of `m/84'/0'/0'/0/i` (note that child keys would not be cached in this case). This parent xpub is not suitable for the normalized descriptor form as we want the key at `m/84'/0'/0'`. So this PR adds another field to `DescriptorCache` to cache the last hardened xpub so that we can use them for normalized descriptors.

  Since `DescriptorCache` is changing, existing descriptor wallets need to be upgraded to use this new cache. The upgrade will occur in the background either at loading time (if the wallet is not encrypted) or at unlocking time in the same manner that `UpgradeKeyMetadata` operates. It will use a new wallet flag `WALLET_FLAG_LAST_HARDENED_XPUB_CACHED` to indicate whether the descriptor wallet has the last hardened xpub cache.

  Lastly `listdescriptors` will not require the wallet to be locked and `getaddressinfo`'s `parent_desc` will always be output (assuming the upgrade has occurred).

Pull request description:

  Builds on top of #22051, adding signing support after derivation support.

  Nothing is changed in descriptor features. Signing works for key path and script path spending, through the normal sending functions, and PSBT-based RPCs. However, PSBT usability is rather low as no extensions have been defined to convey Taproot-specific information, so all script information must be known to the signing wallet.

Pull request description:

  + Remove one character less from wallet path

  + After testing lot of random strings with special chars in `wallet_name`, I found that the issue was not related to special characters in the name. Reviewing PR https://github.com/bitcoin/bitcoin/pull/21907 helped me resolve the issue.

  **Real issue**: If the path mentioned in `walletdir` is a root directory, first character of the wallet name or path is removed

Pull request description:

  Big picture overview in [this gist](https://gist.github.com/Sjors/29d06728c685e6182828c1ce9b74483d).

  This PR adds GUI support for external signers, based on the since merged bitcoin/bitcoin#16546 (RPC).

  The UX isn't amazing - especially the blocking calls - but it works.

  First we adds a GUI setting for the signer script (e.g. path to HWI):

  <img width="625" alt="Schermafbeelding 2019-08-05 om 19 32 59" src="https://user-images.githubusercontent.com/10217/62483415-e1ff1680-b7b7-11e9-97ca-8d2ce54ca1cb.png">

  Then we add an external signer checkbox to the wallet creation dialog:

  <img width="374" alt="Schermafbeelding 2019-11-07 om 19 17 23" src="https://user-images.githubusercontent.com/10217/68416387-b57ee000-0194-11ea-9730-127d60273008.png">

  It's checked by default if HWI detects a device. It also grabs the name. It then creates a fresh wallet and imports the keys.

  You can verify an address on the device (blocking...):
  <img width="673" alt="Schermafbeelding 2019-08-05 om 19 29 22" src="https://user-images.githubusercontent.com/10217/62483560-43bf8080-b7b8-11e9-9902-8a036116dc4b.png">

  Sending, including coin selection, Just Works(tm) as long the device is present.

  ~External signer support is enabled by default when the GUI is configured and Boost::Process is present.~

  External signer support remains disabled by default, see https://github.com/bitcoin/bitcoin/pull/21935.

c7bd5842e4 MOVEONLY: CWallet transaction code out of wallet.cpp/.h (Russell Yanofsky)

Pull request description:

  This commit just moves function without making any changes. It can be reviewed with `git log -p -n1 --color-moved=dimmed_zebra`

  Motivation for this change is to make `wallet.cpp/h` less monolithic and start to make wallet transaction state tracking comprehensible so bugs in https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking can be fixed safely without introducing new problems.

  This moves wallet classes and methods that deal with transactions out of `wallet.cpp/.h` into better organized files:

  - `transaction.cpp/.h` - CWalletTx and CMerkleTx class definitions
  - `receive.cpp/.h` - functions checking received transactions and computing balances
  - `spend.cpp/.h` - functions creating transactions and finding spendable coins

  After #20773, when loading is separated from syncing it will also be possible to move more `wallet.cpp/.h` functions to:

  - `sync.cpp/.h` - functions handling chain notifications and rescanning

  This commit arranges `receive.cpp` and `spend.cpp` functions in dependency order so it's possible to skim `receive.cpp` and get an idea of how computing balances works, and skim `spend.cpp` and get an idea of how transactions are created, without having to jump all over `wallet.cpp` where functions are not in order and there is a lot of unrelated code.

  Followup commit "refactor: Detach wallet transaction methods" in https://github.com/bitcoin/bitcoin/pull/21206 follows up this PR and tweaks function names and arguments to reflect new locations. The two commits are split into separate PRs because this commit is more work to maintain and less work to review, while the other commit is less work to maintain and more work to review, so hopefully this commit can be merged earlier.

Pull request description:

  Changes `KnapsackSolver` to use effective values instead of just the nominal txout value. Since fees are taken into account during the selection itself, we finally get rid of the `CreateTransaction` loop as well as a few other things that only were only necessary because of that loop.

  This should not change coin selection behavior at all (except maybe remove weird edge cases that were caused by the loop). In order to keep behavior the same, `KnapsackSolver` will select outputs with a negative effective value (as it did before).

1a6a0b0dfb wallet: Use existing feerate instead of getting a new one (Andrew Chow)

Pull request description:

  During coin selection, there are various places where we need to have a feerate. We need the feerate for the transaction itself, the discard fee rate, and long term feerate. Fetching these each time we need them can lead to a race condition where two feerates that should be the same are actually different. One particular instance where this can happen is during the loop in `CreateTransactionInternal`. After inputs are chosen, the expected transaction fee is calculated using a newly fetched feerate. If `pick_new_inputs == false`, the loop will go again with the assumption that the fee for the transaction remains the same. However because the feerate is fetched again, it is possible that it actually isn't and this causes coin selection to fail.

  Instead of fetching the feerate each time it is needed, we fetch them all at once at the top of `CreateTransactionInternal`, store them in `CoinSelectionParams`, and use them where needed.

  While some of these fee rates probably don't need this caching, I've done it for consistency and the guarantee that they remain the same.

  Fixes #19229

Samuel Dobson a8b0892b74 Merge #20536: wallet: Error with "Transaction too large" if the funded tx will end up being too large after signing
48a0319bab Add a test that selects too large if BnB is used (Andrew Chow)
3e69939b78 Fail if maximum weight is too large (Andrew Chow)
51e2cd322c Have CalculateMaximumSignedTxSize also compute tx weight (Andrew Chow)

Pull request description:

  Currently the `Transaction too large` is calculated on the transaction that is returned from `CreateTransaction`. This does not make sense for when `CreateTransaction` is being used for `fundrawtransaction` as no signing occurs so the final returned transaction is missing signatures. Thus users may successfully fund a transaction but fail to broadcast it after it has been fully signed.

  So instead we should figure out whether the transaction we are funding will be too large after it is signed. We can do this by having `CalculateMaximumSignedTxSize` also return the transaction weight and then comparing that weight against the maximum weight.

Samuel Dobson 3a2d5bfeb3 Merge #21201: rpc: Disallow sendtoaddress and sendmany when private keys disabled
6bfbc97d71 test: disallow sendtoaddress/sendmany when private keys disabled (Jon Atack)
0997019e76 Disallow sendtoaddress and sendmany when private keys disabled (Andrew Chow)

Pull request description:

  Since `sendtoaddress` and `sendmany` (which use the `SendMoney` function) create and commit a transaction, they should not do anything when the wallet does not have private keys. Otherwise a valid transaction cannot be made.

  Fixes #21104

    ACK 6bfbc97d71. "Error: Private keys are disabled for this wallet" is definitely a better error message than "Insufficient funds" here. Hopefully change of error code from -6 to -4 doesn't break any software using Bitcoin JSON-RPC API.
