Merge bitcoin/bitcoin#33082: wallet, refactor: Remove Legacy check and error

30c6f64eed304560464f9601b80c811c186db20a test: Remove unnecessary LoadWallet() calls (pablomartin4btc)

Pull request description:

  Remove dead code due to legacy wallet removal.

  Leftovers from previous #32481.

  ---

  **Note**:

  While attempting to remove the legacy check in `CWallet::UpgradeDescriptorCache()` (which is called from `DBErrors WalletBatch::LoadWallet(CWallet* pwallet))`, I once again ran into the fact that `LoadWallet()` is used in two distinct scenarios — something I was already aware of:
  - Wallet creation – the upgrade is ignored here because no wallet flags are yet set; attempting to set a flag (ie `WALLET_FLAG_LAST_HARDENED_XPUB_CACHED` at the end of the upgrade function, if the legacy check is removed) would produce a failure (`DBErrors CWallet::LoadWallet()` -> `Assert(m_wallet_flags == 0)`).
  - Wallet loading – the upgrade proceeds correctly and the flag `WALLET_FLAG_LAST_HARDENED_XPUB_CACHED` is set.

  While revisiting this, I also noticed that some `LoadWallet()` calls in the wallet tests are unnecessary and I've removed them in the first commit.

  The following change in `UpgradeDescriptorCache()` could be done in PR #32636 as part of the separation between wallet loading and creation responsibilities.

  ```diff --git a/src/wallet/wallet.cpp b/src/wallet/wallet.cpp

   void CWallet::UpgradeDescriptorCache()
   {
  +    // Only descriptor wallets can upgrade descriptor cache
  +    Assert(IsWalletFlagSet(WALLET_FLAG_DESCRIPTORS));
  +
  -    if (!IsWalletFlagSet(WALLET_FLAG_DESCRIPTORS) || IsLocked() || IsWalletFlagSet(WALLET_FLAG_LAST_HARDENED_XPUB_CACHED)) {
  +    if (IsLocked() || IsWalletFlagSet(WALLET_FLAG_LAST_HARDENED_XPUB_CACHED)) {
           return;
       }
  ```

be776a1443 wallet: Remove isminetype
Since the only remaining isminetypes are ISMINE_NO and ISMINE_SPENDABLE,
this enum is now just a bool and can be removed. IsMine is changed to
return a bool and any usage of isminetypes and isminefilters are changed
to be the remaining ISMINE_SPENDABLE case.

6a7aa01574 wallet: Remove COutput::spendable and AvailableCoinsListUnspent
In descriptor wallets, we consider all outputs to be spendable as we no
longer have mixed mine and watchonly in a wallet. As such,
COutput::spendable is meaningless and can be removed.

Furthermore, CoinFilterParams::only_spendable can be removed as that was
essentially checking for COutput::spendable.

Lastly, AvailableCoinsListUnspent can also be removed as the wrapper is
now only setting the feerate to std::nullopt which is trivial enough that
a dedicated wrapper is not needed.

Pull request description:

  This PR incorporates the suggestion provided by PRabahy and pablomartin4btc in https://github.com/bitcoin/bitcoin/pull/32944 of removing `CWallet::nWalletVersion` and several related functions, such as `SetMinVersion()`, `GetVersion()`, `GetClosestWalletFeature()`, `IsFeatureSupported()`, `CanSupportFeature()`, etc ...

  This field is no longer used in the descriptor wallet and there is still a lot of code related to it, so the changes here provide a good cleanup in the wallet code.

Merge bitcoin/bitcoin#32750: refactor: CFeeRate encapsulates FeeFrac internally
d3b8a54a81209420ef6447dd4581e1b6b8550647 Refactor CFeeRate to use FeeFrac internally (Pol Espinasa)

Pull request description:

  The `FeeFrac` type represents a fraction, intended to be used for `sats/vbyte` or `sats/WU`. It was added to improve accuracy when evaluating fee rates in cluster mempool. [1]
  But it can also be used to fix the precision issues that the current `CFeeRate` class has now.

  At the moment, `CFeeRate` handles the fee rate as  satoshis per kilovirtualbyte: `CAmount / kvB` using an integer.
  This PR fix `CFeeRate` precision issues by encapsulating `FeeFrac` internally keeping backwards compatibility.

  This PR can also be used as a based to use multiple units on RPC calls as detailed in this issue [2].

57fe8acc8a8471ec41ac5f3c3764458431880e4e test: Check max_weight_exceeded error (Murch)

Pull request description:

  I tested all of the reported surviving mutants that @brunoerg reported in https://gist.github.com/brunoerg/834063398d5002f738506d741513e310.

  I found that all Mutants except for 12, 14, 17, 37, and 39 were now being caught by one of the existing tests. This fixes Mutants 14, 37, and 39.

  Mutant 17 is not fixed, because I consider it acceptable that running BnB for 100,001 instead of 100,000 comparisons doesn’t cause an issue, and Mutant 12 is not yet fixed, because at `fee` = `long_term_fee`, the waste of inputs is 0 and only excess matters, and I haven’t evaluated yet, whether it needs to be fixed.

Merge bitcoin/bitcoin#33058: test: add assertions to SRD max weight test
cc33e4578946c68d6d333f35c48f8cbf3f75f6cf test: improve assertion for SRD max weight test (yancy)

Pull request description:

  Replace generic assertion with a result specific assertion showing the correctness of the solution found.  If the max weight parameter is exceeded, the least valuable `UTXOs` are removed from the result. Therefore, only the most valued _encountered_ `UTXO's` are selected. While the smallest set would include all the most valued `UTXO's`, in the case of the test there is one high value `UTXO` that is never found before the target value is reached.

  Correct the test comment to be more specific about why the assertion is a good result.

cc33e45789 test: improve assertion for SRD max weight test
Previously, the assertion only showed that a result was found, however
made no assertion about the quality of the result.

Remove comment about what UTXOs are selected and what are not
since the test does not reflect that.

Pull request description:

  Currently, `unloadwallet` RPC call fails with a JSON parsing error when no `wallet_name` argument is provided. This behavior is misleading because the error originates from a low-level JSON type mismatch, rather than clearly indicating that the wallet name or RPC endpoint (`-rpcwallet=...`) is missing. Also, found out that the [issue](https://github.com/bitcoin/bitcoin/pull/13111#issuecomment-398831543) was noticed during its implementation but never addressed.

  In addition, I've verified all RPC commands calls finding that `getdescriptoractivity` had the same problem, but related to the array input types (blockhashes & descriptors), so I've corrected that RPC as well. For consistency I've added the missing logging info for each test case in `test/functional/rpc_getdescriptoractivity.py` in preparation for the new test.

  Get spend and receive activity associated with a set of descriptors for a set of blocks. This command pairs well with the `relevant_blocks` output of `scanblocks()`.
  This call may take several minutes. If you encounter timeouts, try specifying no RPC timeout (bitcoin-cli -rpcclienttimeout=0)

  1. blockhashes                   (json array, required) The list of blockhashes to examine for activity. Order doesn't matter. Must be along main chain or an error is thrown.

         ...
       ]
  2. scanobjects                   (json array, required) Array of scan objects. Every scan object is either a string descriptor or an object:
       [
         "descriptor",             (string) An output descriptor
         {                         (json object) An object with output descriptor and metadata

           "range": n or [n,n],    (numeric or array, optional, default=1000) The range of HD chain indexes to explore (either end or [begin,end])
         },
         ...
       ]

6135e0553e6e58fcf506700991fa178f2c50a266 wallet, rpc: Move (Un)LockCoin WalletBatch creation out of RPC (Ava Chow)

Pull request description:

  If the locked coin needs to be persisted to the wallet database, insteead of having the RPC figure out when to create a WalletBatch and having LockCoin's behavior depend on it, have LockCoin take whether to persist as a parameter so it makes the batch.

  Since unlocking a persisted locked coin requires a database write as well, we need to track whether the locked coin was persisted to the wallet database so that it can erase the locked coin when necessary.

  Keeping track of whether a locked coin was persisted is also useful information for future PRs.

Pull request description:

  `fclose(3)` may fail to flush the previously written data to disk, thus a failing `fclose(3)` is as serious as a failing `fwrite(3)`.

  Previously the code ignored `fclose(3)` failures. This PR improves that by changing all users of `AutoFile` that use it to write data to explicitly close the file and handle a possible error.

  ---

  Other alternatives are:

  1. `fflush(3)` after each write to the file (and throw if it fails from the `AutoFile::write()` method) and hope that `fclose(3)` will then always succeed. Assert that it succeeds from the destructor 🙄. Will hurt performance.
  2. Throw nevertheless from the destructor. Exception within the exception in C++ I think results in terminating the program without a useful message.
  3. (this is implemented in the latest incarnation of this PR) Redesign `AutoFile` so that its destructor cannot fail. Adjust _all_ its users 😭. For example, if the file has been written to, then require the callers to explicitly call the `AutoFile::fclose()` method before the object goes out of scope. In the destructor, as a sanity check, assume/assert that this is indeed the case. Defeats the purpose of a RAII wrapper for `FILE*` which automatically closes the file when it goes out of scope and there are a lot of users of `AutoFile`.
  4. Pass a new callback function to the `AutoFile` constructor which will be called from the destructor to handle `fclose()` errors, as described in https://github.com/bitcoin/bitcoin/pull/29307#issuecomment-2243842400. My thinking is that if that callback is going to only log a message, then we can log the message directly from the destructor without needing a callback. If the callback is going to do more complicated error handling then it is easier to do that at the call site by directly calling `AutoFile::fclose()` instead of getting the `AutoFile` object out of scope (so that its destructor is called) and inspecting for side effects done by the callback (e.g. set a variable to indicate a failed `fclose()`).

Pull request description:

  Currently, the migration process creates a brand-new descriptor wallet with no
  connection to the user's legacy wallet when the legacy wallet lacks key material
  and contains only watch-only scripts. This behavior is not aligned with user
  expectations. If the legacy wallet contains only watch-only scripts, the migration
  process should only generate a watch-only wallet instead.

  TODO List:
  * Explain that `migratewallet` renames the watch-only after migration, and
  also that the wallet will not have keys enabled.

Explicitly close all AutoFiles that have been written
There is no way to report a close error from `AutoFile` destructor.
Such an error could be serious if the file has been written to because
it may mean the file is now corrupted (same as if write fails).

So, change all users of `AutoFile` that use it to write data to
explicitly close the file and handle a possible error.

6135e0553e wallet, rpc: Move (Un)LockCoin WalletBatch creation out of RPC
If the locked coin needs to be persisted to the wallet database,
insteead of having the RPC figure out when to create a WalletBatch and
having LockCoin's behavior depend on it, have LockCoin take whether to
persist as a parameter so it makes the batch.

Since unlocking a persisted locked coin requires a database write as
well, we need to track whether the locked coin was persisted to the
wallet database so that it can erase the locked coin when necessary.

Keeping track of whether a locked coin was persisted is also useful
information for future PRs.

785e1407b0a39fef81a7b25554aab88d4cecd66b wallet: Use util::Error throughout AddWalletDescriptor (Ava Chow)

Pull request description:

  #32023 changed `AddWalletDescriptor` to return `util::Error`, but did not change all of the failure cases to do so. This may result in some callers continuing when there was actually an error. Unify all of the failure cases to use `util::Error` so that all callers handle `AddWalletDescriptor` errors in the same way.

  The encapsulated return type is changed from `ScriptPubKeyMan*` to `std::reference_wrapper<DescriptorScriptPubKeyMan>`. This avoids having a value that can be interpreted as a bool, and also removes the need to constantly dynamic_cast the returned value. The only kind of `ScriptPubKeyMan` that can come out of `AddWalletDescriptor` is a `DescriptorScriptPubKeyMan` anyways.

Pull request description:

  Currently, we do not add the sighash field to PSBTs at all, even when we have signed with a non-default sighash. This PR changes the behavior such that when we (attempt to) sign with a sighash other than DEFAULT or ALL, the sighash type field will be added to the PSBT to inform the later signers that a different sighash type was used by a signer. Notably, this is necessary for MuSig2 support as all signers must sign using the same sighash type, but the sighash is not provided in partial signatures.

  Furthermore, because the sighash type can also be provided on the command line, we require that if both a command line sighash type and the sighash field is present, they must specify the same sighash type. However, this was being checked by the wallet, rather than the signing code, so the `descriptorprocesspsbt` RPC was not enforcing this restriction at all, and in fact ignored the sighash field entirely. This PR refactors the checking code so that the underlying PSBT signing function `SignPSBTInput` does the check.

Pull request description:

  Implements the idea discussed in https://github.com/bitcoin/bitcoin/pull/29652#issuecomment-2010579484

  Currently, `m_last_block_processed` and `m_last_block_processed_height` are not guaranteed to match the block locator stored in the wallet, nor do either of those fields actually represent the last block that the wallet is synced up to. This is confusing and unintuitive.

  This PR changes those last block fields to be updated whenever the wallet makes a change to the db for new transaction state found in new blocks. Whenever a block is received that contains a transaction relevant to the wallet, the last block locator will now be written to disk. Furthermore, every block disconnection will now write an updated locator.

  To ensure that the locator is relatively recent and loading rescans are fairly quick in the event of unplanned shutdown, it is also now written every 144 blocks (~1 day). Additionally it is now written when the wallet is unloaded so that it is accurate when the wallet is loaded again.

  Lastly, the `chainstateFlushed` notification in the wallet is changed to be a no-op. The best block locator record is no longer written when `chainstateFlushed` is received from the node since it should already be mostly up to date.

7bacabb204 wallet: Update best block record after block dis/connect
When a block is connected, if the new block had anything relevant to the
wallet, update the best block record on disk. If not, also sync the best
block record to disk every 144 blocks.

Also reuse the new WriteBestBlock method in BackupWallet.

Pull request description:

  The final step of #20160.

  A bare minimum of legacy wallet code is kept in order to perform wallet migration. Migration of legacy wallets uses the independent BDB parser and a minimal `LegacyDataSPKM` that allows the legacy data to be loaded so that the migration can be completed.

  BDB has been removed as a dependency and documentation have been updated to reflect that.

Pull request description:

  This PR is splitting off some of the improvements made in #28985 and starts addressing the issues raised in #27754.

  I aim to completely replace `coinselector_tests` with `coinselection_tests`. The goal is to generally use coins created per a nominal _effective value_ so we can get away from testing with `CoinSelectionParams` that are non-representative and effectuate counterintuitive behavior such as `feerate = 0` or `cost_of_change = 0`
