056cb3c0d2 refactor: clear up blockstorage/streams in preparation for optimization
Made every OpenBlockFile#fReadOnly value explicit.

Replaced hard-coded values in ReadRawBlock with STORAGE_HEADER_BYTES.
Changed `STORAGE_HEADER_BYTES` and `UNDO_DATA_DISK_OVERHEAD` to `uint32_t` to avoid casts.

Also added `LIFETIMEBOUND` to the `AutoFile` parameter of `BufferedFile`, which stores a reference to the underlying `AutoFile`, allowing Clang to emit warnings if the referenced `AutoFile` might be destroyed while `BufferedFile` still exists.
Without this attribute, code with lifetime violations wouldn't trigger compiler warnings.

a4de160492 scripted-diff: shorten BLOCK_SERIALIZATION_HEADER_SIZE constant
Renames the constant to be less verbose and better reflect its purpose:
it represents the size of the storage header that precedes serialized block data on disk,
not to be confused with a block's own header.

-BEGIN VERIFY SCRIPT-
git grep -q "STORAGE_HEADER_BYTES" $(git ls-files) && echo "Error: Target name STORAGE_HEADER_BYTES already exists in the codebase" && exit 1

6640dd52c9 Narrow scope of undofile write to avoid possible resource management issue
`AutoFile{OpenUndoFile(pos)}` was still in scope when `FlushUndoFile(pos.nFile)` was called, which could lead to file handle conflicts or other unexpected behavior.

3197155f91 refactor: collect block read operations into try block
Reorganized error handling in block-related operations by grouping related operations together within the same scope.

In `ReadBlockUndo()` and `ReadBlock()`, moved all deserialization operations, comments and checksum verification inside a single try/catch block for cleaner error handling.
In `WriteBlockUndo()`, consolidated hash calculation and data writing operations within a common block to better express their logical relationship.

ci: Slim down lint image
Currently, the lint_test_runner is built and installed into the lint CI
image. This is problematic, because it triggers a full image build on
every change to its source code. Doing a build of the lint test_runner
on every run is easier and faster.

the current image will be EOL in about one year, so it seems fine to

d6244f85c509d7644a57def892298a4dde988c3b depends: Update libmultiprocess library to simplify cmake subtree build (Ryan Ofsky)

Pull request description:

  This adds the [libmultiprocess](https://github.com/chaincodelabs/libmultiprocess) library and code generator as a subtree in `src/ipc/libmultiprocess` and allows it to be built with the cmake `-DENABLE_IPC` option, which is disabled by default.

  This PR does not entirely remove the depends system [libmultiprocess package](https://github.com/bitcoin/bitcoin/blob/master/depends/packages/native_libmultiprocess.mk) because the package is useful when cross compiling. (A cross-compiling cmake build cannot easily build and run a native code generation tool.) However, it does update the depends package to build from the new git subtree, instead of being downloaded separately from github, so the same sources are used to build both the runtime library and the code generator.

  This PR includes the following manual changes (not created automatically with `git subtree add`) which just update the build system and documentation:

7749d929a0 Remove support for RNDR/RNDRRS for aarch64 on Linux
This hardware feature is

- rarely supported on SoCs (and broken on like half of the chips that support it in the first place) (#31817)
- apparently not compiled into the release binary (https://github.com/bitcoin/bitcoin/issues/31817#issuecomment-2795885962)
- hard to test in CI, due to unavailable of hardware

Better to remove it.

This reverts commit aee5404e02e203a256c1a97b629b9b107cc8bb07.

Closes #31817.

Merge bitcoin/bitcoin#31727: miniscript: convert non-critical asserts to CHECK_NONFATAL
ff0194a7ce9dabf1b31b64ca584e45840dce8141 miniscript: convert non-critical asserts to CHECK_NONFATAL (Antoine Poinsot)

Pull request description:

  The Miniscript code contains assertions to prevent ending up in an insane state or prevent UB, but also to enforce logical invariants. For the latter it is not necessary to crash the program if they are broken. Raising an exception suffices, especially as this code is often called through the RPC interface which can in turn handle the exception and the user can report it to developers.

  This revives #28678 from Pieter Wuille.

c47f81e8ac110b1d7f78bce0232e8015366d13e7 net: Rename `_randomize_credentials` Proxy parameter to `tor_stream_isolation` (laanwj)

Pull request description:

  Add a class TorsStreamIsolationCredentialsGenerator that generates unique credentials based on a randomly generated session prefix and an atomic counter. Use this in `ConnectThroughProxy` instead of a simple atomic int counter.

  This makes sure that different launches of the application won't share the same credentials, and thus circuits, even in edge cases.

  Example with `-debug=proxy`:
  ```

Pull request description:

  This should make the `p2p_headers_presync` fuzz target more deterministic.

  Tracking issue: https://github.com/bitcoin/bitcoin/issues/29018.

  The first commits adds an `ElapseSteady` helper and type aliases. The second commit uses those helpers in `ReportHeadersPresync` and in the fuzz target to increase determinism.

  ### Testing

  It can be tested via (setting 32 parallel threads):

  ```
  cargo run --manifest-path ./contrib/devtools/deterministic-fuzz-coverage/Cargo.toml -- $PWD/bld-cmake/ $PWD/../b-c-qa-assets/fuzz_corpora/ p2p_headers_presync 32
  ```

6b63218ec2acebf3555a22923fedf8f080543c61 qt: Update SetHexDeprecated to FromHex (marcofleon)

Pull request description:

  This is part of https://github.com/bitcoin/bitcoin/pull/32189. I'm separating this out because it's not immediately obvious that it's just a refactor. `SetHexDeprecated()` doesn't do any correctness checks on the input, while `FromHex()` does, so it's theoretically possible that there's a behavior change.

  Replaces `uint256::SetHexDeprecated()` calls with `Txid::FromHex()` in four locations:
  - `TransactionTableModel::updateTransaction`
  - `TransactionView::contextualMenu`
  - `TransactionView::abandonTx`
  - `TransactionView::bumpFee`

  The input strings in these cases aren't user input, so they should only be valid hex strings from `GetHex()` (through `TransactionRecord::getTxHash()`). These conversions should be safe without additional checks.

a2bc330da86b604069308f5237b77cfa77ed2b43 feefrac test: avoid integer overflow (bugfix) (Pieter Wuille)

Pull request description:

  The `feefrac_mul_div` fuzz test fails after #30535 with the following (base64) input: `Nb6Fc/97AACAAAD/ewAAgAAAAIAAAACAAAAAoA==` (see https://cirrus-ci.com/task/5240029192126464?logs=ci#L3353).

  This is caused by an internal multiplication inside `CFeeRate` that *just* exceeds the limit of the `int64_t` type. Fix that by tightening the bounds slightly further.

refactor: Use MockableSteadyClock in ReportHeadersPresync
This allows the clock to be mockable in tests. Also, replace cs_main
with GetMutex() while touching this function.

Also, use the ElapseSteady test helper in the p2p_headers_presync fuzz
target to make it more deterministic.

The m_last_presync_update variable is a global that is not reset in
ResetAndInitialize. However, it is only used for logging, so completely
disable it for now.

fuzz: Shuffle files before testing them
When iterating over all fuzz input files in a folder, the order should
not matter.

However, shuffling may be useful to detect non-determinism.

Thus, shuffle in fuzz.cpp, when using neither libFuzzer, nor AFL.

Also, shuffle in the deterministic-fuzz-coverage tool, when using
libFuzzer.

6b63218ec2 qt: Update SetHexDeprecated to FromHex
Replace `uint256::SetHexDeprecated()` calls with `Txid::FromHex()`
in four locations:
- TransactionTableModel::updateTransaction
- TransactionView::contextualMenu
- TransactionView::abandonTx
- TransactionView::bumpFee

The input strings are generally expected to be valid hex strings
from `GetHex()`. However, due to the potentially unpredictable return
value of `.data(TransactionTableModel::TxHashRole)`, check the
`Txid::FromHex` result in `contextualMenu` and return early if the
transaction hash is invalid. The other two functions, `abandonTx`
and `bumpFee` will only be called if the context menu is enabled.

  There turned out to be a mismatch in the tx output counts which caused 'ConnectBlockMixedEcdsaSchnorr' benchmark to run slower than 'ConnectBlockAllEcdsa' and 'ConnectBlockAllSchnorr'. This commit makes the tx output counts uniform across all benchmarks.

  This commit also renames the 'taproot_tx' variable to 'tx' to reflect that this variable represents a general tx and not just a taproot tx.

Merge bitcoin/bitcoin#32214: test: Remove fragile and ancient release 0.17 wallet test
fac978fb213fbd6668194d8b9810ddd10f8a7323 test: Remove fragile and ancient release 0.17 wallet test (MarcoFalke)

Pull request description:

  The test checks that the 0.17 wallet rejects wallet files created in "the future".

  This is nice, and good to know. However,

  * The 0.17 release is ancient and should be unused outside of tests, especially to load future wallets.
  * The test intermittently fails, due to ancient RPC server bugs, that were fixed in the meantime. [1]
  * Albeit they are not identical, the 0.18 release is still checked in this test, so any theoretical bug that would be caught by 0.17 is hopefully still caught by 0.18 as well.

  So fix all issues by removing the test case.

  [1] For example from https://api.cirrus-ci.com/v1/task/6161588714995712/logs/ci.log:

b639417b39cced5223953fca65cdcd5d84475127 net: Add Tor extended SOCKS5 error codes (laanwj)

Pull request description:

  Add support for reporting Tor extended SOCKS5 error codes as defined here:

  - https://spec.torproject.org/socks-extensions.html#extended-error-codes
  - https://gitlab.torproject.org/tpo/core/arti/-/blob/main/crates/tor-socksproto/src/msg.rs?ref_type=heads#L183

  These give a more direct indication of the problem in case of errors connecting to hidden services, for example:
  ```
  2025-04-02T10:34:13Z [net] Socks5() connect to [elided].onion:8333 failed: onion service descriptor can not be found
  ```

  In the C Tor implementation, to get these one should set the "ExtendedErrors" flag on the "SocksPort" definition, introduced in version 0.4.3.1.

  In Arti, extended error codes are always enabled.

  Also, report the raw error code in case of unknown reply values.

751077c6e25e010cff85fe9793a8c5b843350f98 Coins: Add `kHeader` to `CDBBatch::size_estimate` (Lőrinc)

Pull request description:

  ### Summary

  The manual batch size estimation of `CDBBatch` serialized size was [added](e66dbde6d1) when LevelDB [didn't expose this functionality  yet](https://github.com/google/leveldb/commit/69e2bd2).
  The PR refactors the logic to use the native `leveldb::WriteBatch::ApproximateSize()` function, structured in 3 focused commits to incrementally replace the old behavior safely.

  ### Context

  The previous manual size calculation initialized the estimate to 0, instead of LevelDB's header size (containing an 8-byte sequence number followed by a 4-byte count).
  This PR corrects that and transitions to the now-available native LevelDB function for improved accuracy and maintainability.

  ### Approach
  The fix and refactor follow a strangle pattern over three commits:
  * correct the initialization bug in the existing manual calculation, isolating the fix and ensuring the subsequent assertions use the corrected logic;
  * introduce the native `ApproximateSize()` method alongside the corrected manual one, adding assertions to verify their equivalence at runtime;
  * remove the verified manual calculation logic and assertions, leaving only the native method.

Merge bitcoin/bitcoin#32139: test: remove strict restrictions on rpc_deprecated test
459807d566cfddad12b2953a506fd07a129145d8 test: remove strict restrictions on rpc_deprecated (Pol Espinasa)

Pull request description:

  Removed the wallet restrictions for `rpc_deprecated.py` and added specific test case for the current deprecated rpc.
  `skip_test_if_missing_module` will skip the whole test when the wallet is missing, even if a part of the test is non-wallet related. This PR ensures that other tests not related to wallet can be ran and only this specific test will be skipped if there's no wallet

Pull request description:

  Inspired by discussion in https://github.com/bitcoin/bitcoin/pull/31640#issuecomment-2743492906 I made an example adding coverage I think is missing, with some extra commentary that might help future contributors (including myself when I forget how it works again).

  Open for suggestions how we can make it more welcoming beyond this.

Pull request description:

  The `FeeFrac` type represents a fraction, intended to be used for sats/vbyte or sats/WU. This PR adds functionality to evaluate that feerate for a given size, in order to obtain the fee it corresponds with (rounding down, or rounding up).

  The motivation here is being able to do accurate feerate evaluations in cluster mempool block building heuristics (where rounding down is needed), but in principle this makes it possible to use `FeeFrac` as a more accurate replacement for `CFeeRate` (where for feerate estimation rounding up is desirable). Because of this, both rounding modes are implemented.

  Unit tests are included for known-correct values, plus a fuzz test that verifies the result using `arith_uint256`.

These functions are needed to implement FeeFrac evaluation later: given a
FeeFrac{fee, size}, its fee at at_size is (fee * at_size / size).

fcfe008db2 feefrac fuzz: use arith_uint256 instead of ad-hoc multiply
Rather than use an ad-hoc reimplementation of wide multiplication inside the
fuzz test, reuse arith_uint256, which already has this. It's larger than what we
need here, but performance isn't a concern in this test, and it does what we need.

46ff4220bf arith_uint256: modernize comparison operators
Since C++20, operator!= is implicitly defaulted using operator==, and
operator<, operator<=, operator>, and operator>= are defaulted using
operator<=>, so it suffices to just provide these two.

e419b0e17f refactor: Remove manual CDBBatch size estimation
Remove the manual batch size estimation logic (`SizeEstimate()` method and `size_estimate` member) from `CDBBatch`.
Size is now determined solely by the `ApproximateSize()` method introduced in the previous commit, which delegates to the native LevelDB function.

The manual calculation is no longer necessary as LevelDB now provides this functionality directly, and the previous commit verified that the native function's results matched the manual estimation.

Assertions comparing the two methods are removed from `txdb.cpp`.

8b5e19d8b5 refactor: Delegate to LevelDB for CDBBatch size estimation
Serialized batch size can be queried via the underlying LevelDB implementation calling the native `leveldb::WriteBatch::ApproximateSize()`.

The previous manual calculation was added in e66dbde6d1 as part of https://github.com/bitcoin/bitcoin/pull/10195. At that time (April 2017), the version of LevelDB used by Bitcoin Core (and even the latest source) lacked a native function for this. LevelDB added this capability in 69e2bd224b, merged later that year.

The old manual estimation method (`SizeEstimate()`) is kept temporarily in this commit, and assertions are added in `txdb.cpp` to verify its results against `ApproximateSize()` during batch writes. This ensures the native function behaves as expected before removing the manual calculation in the subsequent commit.

751077c6e2 Coins: Add kHeader to CDBBatch::size_estimate
The initialization of the manual `size_estimate` in `CDBBatch::Clear()` is corrected from `0` to `kHeader` (LevelDB's fixed batch header size).
This aligns the manual estimate with LevelDB's actual size immediately after clearing, fixing discrepancies that would otherwise be caught by tests in the next commit (e.g., `coins_tests`, `validation_chainstatemanager_tests`).
