Writing the wallet's `CLIENT_VERSION` (which indicates the last version
to have touched a wallet) needs to be done on both wallet creation and
wallet loading.
The next commit removes the `PopulateWalletFromDatabase()` call from
wallet creation, but this behavior needs to be preserved, so this commit
factors setting `CLIENT_VERSION` out of `PopulateWalletFromDatabase()`
so that wallet creation can use it in the next commit.
Checking every SPKM in `CWallet::Create()` is not necessary, since the
only way presently for an SPKM to get added to `m_spk_managers` (the
return value of `GetAllScriptPubKeyMans()`) is through
`AddScriptPubKeyMan()`, which already invokes `MaybeUpdateBirthTime()`.
`m_keypool_size` must be set before `CWallet::PopulateWalletFromDB()`,
in order to move parsing of `-keypool` into `CWallet::LoadWalletArgs`,
`LoadWalletArgs()` invocation in `CWallet::Create()` must be moved
before `PopulateWalletFromDB()` is called.
This section is necessarily repetitive, makes CWallet::Create() easier
to read, and splits out functionality that will be useful when wallet
creation and loading are separated.

e1dc4afeeb test: Rename wallet name in restore attempt in wallet_assumeutxo (Fabian Jahr)
Pull request description:
I hope this fixes#34354
Based on this error from the logs `filesystem error: cannot remove: The process cannot access the file because it is being used by another process` it looks like there still exists a wallet file by the same name from the previous test case hasn't been cleaned up yet by it's process fully. This should be fixed by giving the failing `restorewallet` case a different wallet name and this shouldn't have any further effects on the rest of the test because is expected to fail anyway. The following (successful) call already uses a different wallet name.

This prevents potential intermittend failures on windows when the wallet by the same name from the previous test case hasn't been cleaned up yet by it's process.
Follow-up to bitcoin/bitcoin#32497.
Clarify why the witness merkle test uses an odd leaf count (it exercises leaf duplication in `ComputeMerkleRoot()`), and make the coinbase witness hash initialization explicit.
Also simplify the leaf-copy loop in the MerkleRoot benchmark for readability.
No production code is changed in this follow-up, for simplicity and safety.

0aba464ce7 test: switch order of error code and message check (rkrux)
Pull request description:
I feel it'd be easier to debug intermittent test failures if the error message is present in the logs instead of error code. So, switching order of error code and message in the `try_rpc` function to aid error debugging.
Should help in debugging #34354 IMO. It's an intermittent failure on Windows that I can't reproduce and it's more difficult to figure out what could have gone wrong only by seeing the error code like below in the CI logs. Given that the functional tests pass, I don't see a harm in checking for error message first and throwing it in case of a mismatch.
```python
AssertionError: Unexpected JSONRPC error code -1

75b704df9d wallettool: Disallow creating new unnamed wallets (Ava Chow)
5875a9c502 wallet: disallow unnamed wallets in createwallet and restorewallet (Ava Chow)
d30ad4a912 wallet, rpc: Use HandleWalletError in createwallet (Ava Chow)
Pull request description:
We've been moving in the direction that all wallets must have a name. Therefore, we shouldn't allow creating new unnamed wallets. `createwallet`, `restorewallet`, and the wallet tool's `create` and `createfromdump` all now require the user to provide a non-empty wallet name when creating/restoring a wallet.
The GUI is already enforcing this, but we were not enforcing it for RPCs or in the underlying `CreateWallet` and `RestoreWallet` functions.
Wallet migration does still need to be able to restore unnamed wallets, so there is a new argument to `RestoreWallet` to explicitly allow that behavior for migration only.

The previous commit added set_ephemeral_port_range() to
avoid port conflicts on FreeBSD by requesting ports from the high
ephemeral range (49152-65535) instead of the default range
which overlaps with the test framework's static port range.
That fix was applied to the SOCKS5 server but not to P2P listeners
created via NetworkThread.create_listen_server(). This commit extends
the fix to cover P2P listeners as well.
When port=0 is requested (dynamic allocation), we now:
1. Manually create a socket with the appropriate address family
2. Call set_ephemeral_port_range() to configure the port range
3. Bind and listen on the socket
4. Pass the pre-configured socket to asyncio's create_server()
This ensures that dynamically allocated ports for P2P listeners also
come from the high range on FreeBSD, avoiding conflicts with the test
framework's static port assignments.

faa18dceba refactor: Use std::bind_front over std::bind (MarcoFalke)
Pull request description:
`std::bind` has many issues:
* It is verbosely listing all placeholders, but in a meaningless way, because it doesn't name the args or their types.
* It silently ignores args passed to it, when one arg is overridden. For example [1] compiles fine on current master.
* Accidentally duplicated placeholders compile fine as well.
* Usually the placeholders aren't even needed.
* This makes it hard to review, understand, and maintain.
Fix all issues by using `std::bind_front` from C++20, which allows to drop the brittle `_1, _2, ...` placeholders. The replacement should be correct, if the trailing placeholders are ordered.
Introducing the same silent bug on top of this pull request [2] will now lead to a compile failure.

3dd815f048 validation: pre-reserve leaves to prevent reallocs with odd vtx count (Lőrinc)
7fd47e0e56 bench: make `MerkleRoot` benchmark more representative (Lőrinc)
f0a2183108 test: adjust `ComputeMerkleRoot` tests (Lőrinc)
Pull request description:
#### Summary
`ComputeMerkleRoot` [duplicates the last hash](39b6c139bd/src/consensus/merkle.cpp (L54-L56)) when the input size is odd. If the caller provides a `std::vector` whose capacity equals its size, that extra `push_back` forces a reallocation, doubling its capacity (causing peak memory usage of 3x the necessary size).
This affects roughly half of the created blocks (those with odd transaction counts), causing unnecessary memory fragmentation during every block validation.
#### Fix
* Pre-reserves vector capacity to account for the odd-count duplication using `(size + 1) & ~1ULL`.
* This syntax produces [optimal assembly](https://github.com/bitcoin/bitcoin/pull/32497#discussion_r2553107836) across x86/ARM and 32/64-bit platforms for GCC & Clang.
* Eliminates default construction of `uint256` objects that are immediately overwritten by switching from `resize` to `reserve` + `push_back`.
#### Memory Impact
[Memory profiling](https://github.com/bitcoin/bitcoin/pull/32497#issuecomment-3563724551) shows **50% reduction in peak allocation** (576KB → 288KB) and elimination of reallocation overhead.
#### Validation
The benchmark was updated to use an odd leaf count to demonstrate the real-world scenario where the reallocation occurs.
A full `-reindex-chainstate` up to block **896 408** ran without triggering the asserts.
<details>
<summary>Validation asserts</summary>
Temporary asserts (not included in this PR) confirm that `push_back` never reallocates and that the coinbase witness hash remains null:
```cpp
if (hashes.size() & 1) {
assert(hashes.size() < hashes.capacity()); // TODO remove
hashes.push_back(hashes.back());
}
leaves.reserve((block.vtx.size() + 1) & ~1ULL); // capacity rounded up to even
leaves.emplace_back();
assert(leaves.back().IsNull()); // TODO remove
```
</details>
#### Benchmark Performance
While the main purpose is to improve predictability, the reduced memory operations also improve hashing throughput slightly.

1658b8f82b refactor: rename `CTransaction::GetTotalSize` to signal that it's not cached (Lőrinc)
Pull request description:
### Context
The new accounting options introduced in https://github.com/bitcoin/bitcoin/pull/32582 can be quite heavy, and are not needed when debug logging is disabled.
### Problem
`PartiallyDownloadedBlock::FillBlock()` and `PeerManagerImpl::SendBlockTransactions()` accumulate transaction sizes for debug logging by calling `ComputeTotalSize()` in loops, which invokes expensive `GetSerializeSize()` serializations.
The block header hash is also only computed for the debug log.
### Fixes
Guard the size and hash calculations with `LogAcceptCategory()` checks so the serialization and hashing work only occurs when compact block debug logging is enabled.
Also modernized the surrounding code a bit since the change is quite trivial.
### Reproducer
You can test the change by starting an up-to-date `bitcoind` node with `-debug=cmpctblock` and observing compact block log lines such as:
> [cmpctblock] Successfully reconstructed block 00000000000000000001061eaa6c0fe79258e7f79606e67ac495765cb121a520 with 1 txn prefilled, 3122 txn from mempool (incl at least 3 from extra pool) and 641 txn (352126 bytes) requested

Any issues in musig2.{cpp,h} will likely also be caught by the descriptor tests, but having more detailed tests for the MuSig2 class itself improves test reporting/coverage.
It uses BIP 328 test vectors.

This aligns it more with SanityCheckAsmap and reduces variable scope.
Also unify asmap casing in SanityCheckAsmap function name.

This prevents holding the asmap data in memory twice.
The version hash changes due to spans being serialized without their size-prefix (unlike vectors).
Calculate the asmap version only in one place: A dedicated function in util/asmap.
The version was also referred to as asmap checksum in several places. To avoid confusion call it asmap version everywhere.
