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.

cd97905ebc564b8b095099a28d1d5437951927c4 cmake: Move internal binaries from bin/ to libexec/ (Ryan Ofsky)

Pull request description:

  This change moves binaries that are not typically invoked directly by users from the `bin/` directory to the `libexec/` directory in CMake installs and binary releases. The goal of the PR is to introduce a distinction between internal and external binaries so starting with #31802, we can use IPC to implement features in new binaries without adding those binaries to the CLI. The change also helps reduce clutter in `bin/`, making it easier for users to identify useful tools to run. Summary of changes:

  - For **source builds** (i.e. developer builds) — There are no changes.
  - For **source installs** (i.e. `cmake --install` result) — `test_bitcoin`, `test_bitcoin-qt`, and `bench_bitcoin` are installed in `${CMAKE_PREFIX_PATH}/libexec` instead of `${CMAKE_PREFIX_PATH}/bin`, so they are no longer on the system `PATH`. However, they can still be invoked from the `libexec/` directory, or from the CLI as `bitcoin test`, `bitcoin test-gui`, and `bitcoin bench`, respectively.
  - For **binary releases** — Since `test_bitcoin` is the only test binary enabled in releases, the only change is moving `test_bitcoin` from `bin/` to `libexec/`.

Pull request description:

  Part of #30289. Builds on top of #31553.

  So far, the `TxGraph::DoWork()` function took no parameters, and just made all clusters reach the "acceptable" internal quality level by performing a minimum number of improvement iterations on it, but:
  * Did not attempt to go beyond that.
  * Was broken, as the QualityLevel of optimal clusters that merge together was not being reset.

  Fix this by adding an argument to `DoWork()` to control how much work it is allowed to do right now, which will first be used to get all clusters to the acceptable level, and if more budget remains, use it to try to get some or all clusters optimal. The function will now return `true` if all clusters are known to be optimal (and thus no further work remains). This is verified in the tests, by remembering whether the graph is optimal, and if it is at the end of the simulation run, verify that the overall linearization cannot be improved further.

Pull request description:

  This change is part of [[IBD] - Tracking PR for speeding up Initial Block Download](https://github.com/bitcoin/bitcoin/pull/32043)

  ### Summary

  Current block obfuscations are done byte-by-byte, this PR batches them to 64 bit primitives to speed up obfuscating bigger memory batches.
  This is especially relevant now that https://github.com/bitcoin/bitcoin/pull/31551 was merged, having bigger obfuscatable chunks.

  Since this obfuscation is optional, the speedup measured here depends on whether it's a [random value](https://github.com/bitcoin/bitcoin/pull/31144#issuecomment-2523295114) or [completely turned off](https://github.com/bitcoin/bitcoin/pull/31144#issuecomment-2519764142) (i.e. XOR-ing with 0).

  ### Changes in testing, benchmarking and implementation

  * Added new tests comparing randomized inputs against a trivial implementation and performing roundtrip checks with random chunks.
  * Migrated `std::vector<std::byte>(8)` keys to plain `uint64_t`;
  * Process unaligned bytes separately and unroll body to 64 bytes.

  ### Assembly

  Memory alignment is enforced by a small peel-loop (`std::memcpy` is optimized out on tested platform), with an `std::assume_aligned<8>` check, see the Godbolt listing at https://godbolt.org/z/59EMv7h6Y for details

  </details>

  ### Endianness

  The only endianness issue was with bit rotation, intended to realign the key if obfuscation halted before full key consumption.
  Elsewhere, memory is read, processed, and written back in the same endianness, preserving byte order.
  Since CI lacks a big-endian machine, testing was done locally via Docker.

972697976c bench: make ObfuscationBench more representative
A previous PR already solved the tiny byte-array-xors during serialization, so it makes sense to keep focusing on the performance of bigger continuous chunks.

This also renames the file from `xor` to `obfuscation` to enable scripted diff name unification later.

0f86da382d3fdca6fc69ff277794acbc3f1e928d wallet: remove dead code in legacy wallet migration (rkrux)

Pull request description:

  A discussion on a previous [PR 32481](https://github.com/bitcoin/bitcoin/pull/32481#discussion_r2145152084) related to legacy wallet dead
  code removal made me realize that checking if the legacy
  wallet was loaded prior to the start of the migration is not
  required ever since legacy wallets can't be loaded in the first
  place. I also verified that the `load_on_start` persistent
  setting can also not cause the legacy wallets to be loaded, which
  further makes the case for removal of the above mentioned checks
  during migration.
  The current test coverage also shows these lines uncovered.

Pull request description:

  It is a bit confusing that one bench run, when aborted, could leave behind temp files in the current working directory. It is similarly confusing to delete those files in the next run of bench.

  Fix all issues by using `BasicTestingSetup`, which provides a proper temp folder to use and also cleans up after itself.

  Can be tested via:

  ```
  ( echo 'my file content' > streams_tmp ) && ls streams_tmp && ./bld-cmake/bin/bench_bitcoin --filter=FindByte && ls streams_tmp
  ```

  Previously the file would be deleted, now it is kept.

Pull request description:

  Part of cluster mempool (#30289).

  During reorganisations, it is possible that dependencies get added which would result in clusters that violate policy limits (cluster count, cluster weight), when linking the new from-block transactions to the old from-mempool transactions. Unlike RBF scenarios, we cannot simply reject the changes when they are due to received blocks. To accommodate this, add a `TxGraph::Trim()`, which removes some subset of transactions (including descendants) in order to make all resulting clusters satisfy the limits.

  Conceptually, the way this is done is by defining a rudimentary linearization for the entire would-be too-large cluster, iterating it from beginning to end, and reasoning about the counts and weights of the clusters that would be reached using transactions up to that point. If a transaction is encountered whose addition would violate the limit, it is removed, together with all its descendants.

  This rudimentary linearization is like a merge sort of the chunks of the clusters being combined, but respecting topology. More specifically, it is continuously picking the highest-chunk-feerate remaining transaction among those which have no unmet dependencies left. For efficiency, this rudimentary linearization is computed lazily, by putting all viable transactions in a heap, sorted by chunk feerate, and adding new transactions to it as they become viable.

  The `Trim()` function is rather unusual compared to the `TxGraph` functionality added in previous PRs, in that `Trim()` makes it own decisions about what the resulting graph contents will be, without good specification of how it makes that decision - it is just a best-effort attempt (which is improved in the last commit). All other `TxGraph` mutators are simply to inform the graph about changes the calling mempool code decided on; this one lets the decision be made by txgraph.

  As part of this, the "oversized" property is expanded to also encompass a configurable cluster weight limit (in addition to cluster count limit).

  `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()`).

wallet: remove dead code in legacy wallet migration
A discussion on a previous PR 32481 related to legacy wallet dead
code removal made me realize that checking if the legacy
wallet was loaded prior to the start of the migration is not
required ever since legacy wallets can't be loaded in the first
place. I also verified that the `load_on_start` persistent
setting can also not cause the legacy wallets to be loaded, which
further makes the case for removal of the above mentioned checks
during migration.
The current test coverage also shows these lines uncovered.

1632fc104b txgraph: Track multiple potential would-be clusters in Trim (improvement)
In the existing Trim function, as soon as the set of accepted transactions
would exceed the max cluster size or count limit, the acceptance loop is
stopped, removing all later transactions. However, it is possible that by
excluding some of those transactions the would-be cluster splits apart into
multiple would-clusters. And those clusters may well permit far more
transactions before their limits are reached.

Take this into account by using a union-find structure inside TrimTxData to
keep track of the count/size of all would-be clusters that would be formed
at any point, and only reject transactions which would cause these resulting
partitions to exceed their limits.

This is not an optimization in terms of CPU usage or memory; it just
improves the quality of the transactions removed by Trim().

Pull request description:

  Currently, the wallet is not actually aware about its own transaction outputs. Instead, it will iterate all of the transactions stored in `mapWallet`, and then all of the outputs of those transactions, in order to figure out what belongs to it for the purposes of coin selection and balance calculation. For balance calculation, there is caching that results in it only iterating all of the transactions, but not all of the outputs. However when the cache is dirty, everything is iterated. This is especially problematic for wallets that have a lot of transactions, or transactions that have a lot of unrelated outputs (as may occur with coinjoins or batched payments).

  This PR helps to resolve this issue by making the wallet track all of the outputs that belong to it in a new member `m_txos`. Note that this includes outputs that may have already been spent. Both balance calculation (`GetBalance`) and coin selection (`AvailableCoins`) are updated to iterate `m_txos`. This is generally faster since it ignores all of the unrelated outputs, and it is not slower as in the worst case of wallets containing only single output transactions, it's exactly the same number of outputs iterated.

  `m_txos` is memory only, and it is populated during wallet loading. When each transaction is loaded, all of its outputs are checked to see if it is `IsMine`, and if so, an entry added to `m_txos`. When new transactions are received, the same procedure is done.

  Since imports can change the `IsMine` status of a transaction (although they can only be "promoted" from watchonly to spendable), all of the import RPCs will be a bit slower as they re-iterate all transactions and all outputs to update `m_txos`.

  Each output in `m_txos` is stored in a new `WalletTXO` class. This class contains references to the parent `CWalletTx` and the `CTxOut` itself. It also caches the `IsMine` value of the txout. This should be safe as `IsMine` should not change unless there are imports. This allows us to have additional performance improvements in places that use these `WalletTXO`s as they can use the cached `IsMine` rather than repeatedly calling `IsMine` which can be expensive.

  The existing `WalletBalance` benchmark demonstrates the performance improvement that this PR makes. The existing `WalletAvailableCoins` benchmark doesn't as all of the outputs used in that benchmark belong to the test wallet. I've updated that benchmark to have a bunch of unrelated outputs in each transaction so that the difference is demonstrated.

  This is part of a larger project to have the wallet actually track and store a set of its UTXOs.

  Built on #24914 as it requires loading the txs last in order for `m_txos` to be built correctly.

Pull request description:

  A follow-up to https://github.com/bitcoin/bitcoin/pull/32487#discussion_r2094072165, after which validating the hash of a read block from disk doesn't incur the cost of calculating its hash anymore.

  ### Summary

  This PR adds explicit checks that the read block header's hash matches the one we were expecting.

  ### Context

  After the previous PR, validating a block's hash during read operations became essentially free. This PR leverages that by requiring callers to provide a block's expected hash (or `std::nullopt`), preventing silent failures caused by corrupted or mismatched data. Most `ReadBlock` usages were updated with expected hashes and now fail on mismatch.

  ### Changes

  * added hash assertions in `ProcessGetBlockData` and `ProcessMessage` to validate that the block read from disk matches the expected hash;
  * updated tests and benchmark to pass the correct block hash to `ReadBlock()`, ensuring the hash validation is tested - or none if we already expect PoW failure;
  * removed the default value for `expected_hash`, requiring an explicit hash for all block reads.

  ### Why is the hash still optional (but no longer has a default value)

  * for header-error tests, where the goal is to trigger failures early in the parsing process;
  * for out-of-order orphan blocks, where the child hash isn't available before the initial disk read.

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.

Switch to the index-aware `ReadBlock()` overload in `ComputeFilter` so that filter creation will abort if the stored block header hash doesn't match the expected one.

In the `readwriteblock` benchmark, pass the expected hash to `ReadBlock()` to match the new signature without affecting benchmark performance.

Historically, the headers have been bumped some time after a file has

cd97905ebc cmake: Move internal binaries from bin/ to libexec/
This change moves binaries that are not typically invoked directly by users
from the `bin/` directory to the `libexec/` directory in CMake installs and
binary releases. The goal is to simplify the contents of `bin/` for end users
while still making all binaries available when needed. After this change, the
binaries remaining in `bin/` are:

- bitcoin
- bitcoin-cli
- bitcoind
- bitcoin-qt
- bitcoin-tx
- bitcoin-util
- bitcoin-wallet

And the binaries that are moved to `libexec/` are:

- bench_bitcoin
- bitcoin-chainstate(*)
- bitcoin-gui(***)
- bitcoin-node(***)
- test_bitcoin(**)
- test_bitcoin-qt

(*) bitcoin-chainstate was previously missing an install rule and was actually
not installed even when it was enabled.

(**) test_bitcoin is the only libexec/ binary that is currently included in
bitcoin binary releases. The others are only installed when building from
source with relevant cmake options enabled.

(***) bitcoin-node and bitcoin-gui are not currently built by default or
included in binary releases but both of these changes are planned and
implemented in #31802

11fed833b3ed6d5c96957de5addc4f903b2cee6c threading: add LOCK_ARGS macro (Cory Fields)

Pull request description:

  As part of an effort to cleanup our threading primitives and add safe `SharedMutex`/`SharedLock` impls, I'd like to get rid of the last of our legacy `ENTER_CRITICAL_SECTION`/`LEAVE_CRITICAL_SECTION` usage. This, along with a follow-up [after fixing REVERSE_LOCK](https://github.com/bitcoin/bitcoin/pull/32465) will allow us to do that.

  This replaces the old macros with an RAII lock, while simplifying `CCheckQueueControl`. It now requires a `CCheckQueue`, and optionality is handled externally. In the case of validation, it is wrapped in a `std::optional`.

  It also adds an `LOCK_ARGS` macro for `UniqueLock` initialization which may be helpful elsewhere.

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.

7bacabb204b6c34f9545f0b37e2c66296ad2c0de wallet: Update best block record after block dis/connect (Ava Chow)

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.

remove unused GetDestinationForKey
It is only used in test. There it is problematic, because it sometimes
relies on m_default_address_type. If the default were changed to
BECH32M, those tests would fail the assert(false).

So just use PKHash{} in all tests and remove GetDestinationForKey.

98a1a5275c wallet: Remove chainStateFlushed
chainStateFlushed is no longer needed since the best block is updated
after a block is scanned. Since the chainstate being flushed does not
necessarily coincide with the wallet having processed said block, it
does not entirely make sense for the wallet to be recording that block
as its best block, and this can cause race conditions where some blocks
are not processed. Thus, remove this notification.

7fd3e1cf0c wallet, bench: Write a bestblock record in WalletMigration
Migrating a wallet requires having a bestblock record. This is always
the case in normal operation as such a record is always written on
wallet loading if it didn't already exist. However, within the unit
tests and benchmarks, this is not guaranteed. Since migration requires
the record, WalletMigration needs to also add this record before the
benchmark.

Merge bitcoin/bitcoin#32023: wallet: removed duplicate call to GetDescriptorScriptPubKeyMan
55b931934a34bab11446e8eed7bdaef92bb056de removed duplicate calling of GetDescriptorScriptPubKeyMan (Saikiran)

Pull request description:

  Removed duplicate call to GetDescriptorScriptPubKeyMan and
  Instead of checking linearly I have used find method so time complexity reduced significantly for GetDescriptorScriptPubKeyMan
  after this fix improved performance of importdescriptor part refs https://github.com/bitcoin/bitcoin/issues/32013.

  **Steps to reproduce in testnet environment**

  **Input size:** 2 million address in the wallet

  **Step1:** call importaddresdescriptor rpc method
  observe the time it has taken.

  **With the provided fix:**
  Do the same steps again
  observe the time it has taken.

  There is a huge improvement in the performance. (previously it may take 5 to 6 seconds now it will take 1 seconds or less)

  main changes i've made during this pr:

  1. remove duplicate call to GetDescriptorScriptPubKeyMan method
  2. And inside GetDescriptorScriptPubKeyMan method previously we checking **each address linearly** so each time it is calling HasWallet method which has aquired lock.
  3. Now i've modified this logic call **find method on the map (O(logn)**) time it is taking, so only once we calling HasWallet method.

  **Note:** Smaller inputs in the wallet you may not see the issue but huge wallet size it will definitely impact the performance.
