log: Remove function name from init logs
It is redundant with -logsourcelocations and the log messages are
clearer without it.

Also, remove a double-space.

Also, add braces around `if` touched in the next commit.

This tiny behavior change requires a test fixup.

Merge bitcoin/bitcoin#32827: mempool: Avoid needless vtx iteration during IBD
249889bee6b88eb9814eb969e6fb108f86a4bf98 orphanage: avoid vtx iteration when no orphans (furszy)
41ad2be4340d7b18a4669aa9becef8936597f000 mempool: Avoid expensive loop in `removeForBlock` during IBD (Lőrinc)

Pull request description:

  During Initial Block Download, the mempool is usually empty, but `CTxMemPool::removeForBlock` is still called for every connected block where we:
  * iterate over every transaction in the block even though none will be found in the empty `mapTx`, always leaving `txs_removed_for_block` empty...
  * which is pre-allocated regardless with `40 bytes * vtx.size()`, even though it will always remain empty.

  Similarly to https://github.com/bitcoin/bitcoin/pull/32730#discussion_r2140691354, this change introduces a minor performance & memory optimization by only executing the loop if any of the affected mempool maps have any contents. The second commit is cherry-picked from there since it's related to this change as well.

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>
  <summary>Details</summary>

  Target & Compiler | Stride (per hot-loop iter) | Main operation(s) in loop | Effective XORs / iter
  -- | -- | -- | --
  Clang x86-64 (trunk) | 64 bytes | 4 × movdqu → pxor → store | 8 × 64-bit
  GCC x86-64 (trunk) | 64 bytes | 4 × movdqu/pxor sequence, enabled by 8-way unroll | 8 × 64-bit
  GCC RV32 (trunk) | 8 bytes | copy 8 B to temp → 2 × 32-bit XOR → copy back | 1 × 64-bit (as 2 × 32-bit)
  GCC s390x (big-endian 14.2) | 64 bytes | 8 × XC (mem-mem 8-B XOR) with key cached on stack | 8 × 64-bit

  </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.

03aaaedc6d [prep] Return the made-reconsiderable announcements in AddChildrenToWorkSet
This is preparation for the simulation fuzz test added in a later commit. Since
AddChildrenToWorkSet consumes randomness, there is no way for the simulator to
exactly predict its behavior. By returning the set of made-reconsiderable announcements
instead, the simulator can instead test that it is *a* valid choice, and then
apply it to its own data structures.

ea29c4371e [p2p] bump DEFAULT_MAX_ORPHANAGE_LATENCY_SCORE to 3,000
For the default number of peers (125), allows each to relay a default
descendant package (up to 25-1=24 can be missing inputs) of small (9
inputs or fewer) transactions out of order.

This limit also gives acceptable bounds for worst case LimitOrphans iterations.

Functional tests aren't changed to check for larger cap because it would
make the runtime too long.

Also deletes the now-unused DEFAULT_MAX_ORPHAN_TRANSACTIONS.

067365d2a8 [p2p] overhaul TxOrphanage with smarter limits
This is largely a reimplementation using boost::multi_index_container.
All the same public methods are available. It has an index by outpoint,
per-peer tracking, peer worksets, etc.

A few differences:
- Limits have changed: instead of a global limit of 100 unique orphans,
  we have a maximum number of announcements (which can include duplicate
orphans) and a global memory limit which scales with the number of
peers.
- The maximum announcements limit is 100 to match the original limit,
  but this is actually a stricter limit because the announcement count
is not de-duplicated.
- Eviction strategy: when global limits are reached, a per-peer limit
  comes into play. While limits are exceeded, we choose the peer whose
“DoS score” (max usage / limit ratio for announcements and memory
limits) is highest and evict announcements by entry time, sorting
non-reconsiderable ones before reconsiderable ones. Since announcements
are unique by (wtxid, peer), as long as 1 announcement remains for a
transaction, it remains in the orphanage.
- This eviction strategy means no peer can influence the eviction of
  another peer’s orphans.
- Also, since global limits are a multiple of per-peer limits, as long
  as a peer does not exceed its limits, its orphans are protected from
eviction.
- Orphans no longer expire, since older announcements are generally
  removed before newer ones.
- GetChildrenFromSamePeer returns the transactions from newest to
  oldest.

Pull request description:

  Part of the [type safety refactor](https://github.com/bitcoin/bitcoin/pull/32189).

  This PR changes the GenTxid class to a variant, which holds both Txids and Wtxids. This provides compile-time type safety and eliminates the manual type check (bool m_is_wtxid). Variables that can be either a Txid or a Wtxid are now using the new GenTxid variant, instead of uint256.

8a1765795fd3bff79d790102ca7cefa8fd9b204c use WalletContext scheduler for walletpassphrase callback (Matthew Zipkin)

Pull request description:

  This removes the dependency on libevent for events scheduled by RPC commands, like re-locking a wallet some time after decryption with walletpassphrase. Since walletpassphrase is currently the only RPC that does this, `RPCRunLater`, `RPCTimerInterface` and all related methods are left unused, and deleted in the second commit. Any future RPC that needs to execute a callback in the future can follow the pattern in this PR and just use a scheduler from node or wallet context.

  This is an alternative approach to #32796, described in https://github.com/bitcoin/bitcoin/pull/32796#issuecomment-3014309449

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:

  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.

Pull request description:

  This PR adds the IPC equivalent of the `getblocktemplate` RPC in `proposal` mode.

  In order to do so it has `TestBlockValidity` return error reasons as a string instead of `BlockValidationState`. This avoids complexity in IPC code for handling the latter struct.

  The new Mining interface method is used in `miner_tests`.

  It's not used by the `getblocktemplate` and `generateblock` RPC calls, see https://github.com/bitcoin/bitcoin/pull/31981#discussion_r2096473337

  The `inconclusive-not-best-prevblk` check is moved from RPC
  code to `TestBlockValidity`.

  Test coverage is increased by `mining_template_verification.py`.

  Superseedes #31564

  ## Background

  ### Verifying block templates (no PoW)

  Stratum v2 allows miners to generate their own block template. Pools may wish (or need) to verify these templates. This typically involves comparing mempools, asking miners to providing missing transactions and then reconstructing the proposed block.[^0] This is not sufficient to ensure a proposed block is actually valid. In some schemes miners could take advantage of incomplete validation[^1].

  The Stratum Reference Implementation (SRI), currently the only Stratum v2 implementation, collects all missing mempool transactions, but does not yet fully verify the block.[^2]. It could use the `getblocktemplate` RPC in `proposal` mode, but using IPC is more performant, as it avoids serialising up to 4 MB of transaction data as JSON.

  (although SRI could use this PR, the Template Provider role doesn't need it, so this is _not_ part of #31098)

832c57a53410870471a52647ce107454de3bc69c thread-safety: modernize thread safety macros (Cory Fields)

Pull request description:

  This is one of several PRs to cleanup/modernize our threading primitives.

  While replacing the old critical section locks in the mining code with a `REVERSE_LOCK`, I noticed that our thread-safety annotations weren't hooked up to it. This PR gets `REVERSE_LOCK` working properly.

  Firstly it modernizes the attributes as-recommended by the [clang docs](https://clang.llvm.org/docs/ThreadSafetyAnalysis.html) (ctrl+f for `USE_LOCK_STYLE_THREAD_SAFETY_ATTRIBUTES`). There's a subtle difference between the old `unlock_function` and new `release_capability`, where our `reverse_lock` only works with the latter. I believe this is an upstream bug. I've [reported and attempted a fix here](https://github.com/llvm/llvm-project/pull/139343), but either way it makes sense to me to modernize.

  The second adds a missing annotation pointed out by a fixed `REVERSE_LOCK`. Because clang's thread-safety annotations aren't passed through a reference to `UniqueLock` as one may assume (see [here](https://clang.llvm.org/docs/ThreadSafetyAnalysis.html#no-alias-analysis) for more details), `cs_main` has to be listed explicitly as a requirement.

  The last commit actually fixes the `reverse_lock` by making it a `SCOPED_LOCK` and using the pattern [found in a clang test](https://github.com/llvm/llvm-project/blob/main/clang/test/SemaCXX/warn-thread-safety-analysis.cpp#L3126). Though the docs don't describe how to accomplish it, the functionality was added [in this commit](6a68efc959). Due to aliasing issues (see link above), in order to work correctly, the original mutex has to be passed along with the lock, so all existing `REVERSE_LOCK`s have been updated. To ensure that the mutexes actually match, a runtime assertion is added.

a201a99f8c thread-safety: fix annotations with REVERSE_LOCK
Without proper annotations, clang thinks that mutexes are still held for the
duration of a reverse_lock. This could lead to subtle bugs as
EXCLUSIVE_LOCKS_REQUIRED(foo) passes when it shouldn't.

As mentioned in the docs [0], clang's thread-safety analyzer is unable to deal
with aliases of mutexes, so it is not possible to use the lock's copy of the
mutex for that purpose. Instead, the original mutex needs to be passed back to
the reverse_lock for the sake of thread-safety analysis, but it is not actually
used otherwise.

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.

Add checkBlock to Mining interface
Use it in miner_tests.

The getblocktemplate and generateblock RPC calls don't use this,
because it would make the code more verbose.

validation: refactor TestBlockValidity
Comments are expanded.

Return BlockValidationState instead of passing a reference.
Lock Chainman mutex instead of cs_main.
Remove redundant chainparams and pindexPrev arguments.
Drop defaults for checking proof-of-work and merkle root.

The ContextualCheckBlockHeader check is moved to after CheckBlock,
which is more similar to normal validation where context-free checks
are done first.

Validation failure reasons are no longer printed through LogError(),
since it depends on the caller whether this implies an actual bug
in the node, or an externally sourced block that happens to be invalid.
When called from getblocktemplate, via BlockAssembler::CreateNewBlock(),
this method already throws an std::runtime_error if validation fails.

Additionally it moves the inconclusive-not-best-prevblk check from RPC
code to TestBlockValidity.

There is no behavior change when callling getblocktemplate with proposal.
Previously this would return a BIP22ValidationResult which can throw for
state.IsError(). But CheckBlock() and the functions it calls only use
state.IsValid().

The final assert is changed into Assume, with a LogError.

9341b5333a blockstorage: make block read hash checks explicit
Dropped the default expected_hash parameter from `ReadBlock()`.

In `blockmanager_flush_block_file` tests, we pass {} since the tests would already fail at PoW validation for corrupted blocks.

In `ChainstateManager::LoadExternalBlockFile`, we pass {} when processing child blocks because their hashes aren't known beforehand.

Pull request description:

  Some users really seem to care about this. While it shouldn't matter much, the diff is so trivial that it is probably worth doing.

  Fixes #31127

  One could also consider to split the field into two dedicated ones (https://github.com/bitcoin/bitcoin/issues/28847#issuecomment-1807115357), but this is left for a more involved follow-up and may also be controversial.

Pull request description:

  Eliminate one block header hash calculation per block-read by reusing the hash for:
  * proof‑of‑work verification;
  * (optional) integrity check against the supplied hash.

  This part of the code wasn't covered by tests either, so the first commit exercises this part first, before pushing the validation to the delegate method.

It is cheap to calculate and the caller does not have to take a lock to

Also turn pointers that can never be null into references.

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.
