dcb56fd4cb interfaces: add interruptWait method (ismaelsadeeq)
Pull request description:
This is an attempt to fix#33575 see the issue for background and the usefulness of this feature.
This PR uses one of the suggested approaches: adding a new `interruptWaitNext()` method to the mining interface.
It introduces a new boolean variable, `m_interrupt_wait`, which is set to `false` when the thread starts waiting. The `interruptWaitNext()` method wakes the thread and sets `m_interrupt_wait` to `true`.
Whenever the thread wakes up, it checks whether the wait was aborted; if so, it simply set ` m_interrupt_wait ` to false and return`nullptr`.
This PR also adds a functional test for the new method. The test uses `asyncio` to spawn two tasks and attempts to ensure that the wait is executed before the interrupt by using an event monitor. It adds a 0.1-second buffer to ensure the wait has started executing.
If that buffer elapses without `waitNext` executing, the test will fail because a transaction is created after the buffer.

Code review ACK dcb56fd4cb, just tweaking semantics slightly since last review so if an `interruptWait` call is made shortly after a `waitNext` call it will reliably cause the `waitNext` call to return right away without blocking, even if the `waitNext` call had not begun to execute or wait yet.

ec8516ceb7 test: remove obsolete `get_{key,multisig}` helpers from wallet_util.py (Sebastian Falbesoner)
Pull request description:
This small cleanup PR is a late follow-up to #31250 (commit c847dee148). These helpers are unused and wouldn't work anymore, as they call a legacy wallet RPC (`dumpprivkey`). They were only ever used for testing the `importmulti` RPC, which also doesn't exist anymore. Functional tests that need to create key pairs and derive various output script types from them can use `get_generate_key` (introduced in #16528, commit f193ea889d) instead, without involving the node.

Pull request description:
This is a first attempt at introducing a C header for the libbitcoinkernel library that may be used by external applications for interfacing with Bitcoin Core's validation logic. It currently is limited to operations on blocks. This is a conscious choice, since it already offers a lot of powerful functionality, but sits just on the cusp of still being reviewable scope-wise while giving some pointers on how the rest of the API could look like.
The current design was informed by the development of some tools using the C header:
* A re-implementation (part of this pull request) of [bitcoin-chainstate](https://github.com/bitcoin/bitcoin/blob/master/src/bitcoin-chainstate.cpp).
* A re-implementation of the python [block linearize](https://github.com/bitcoin/bitcoin/tree/master/contrib/linearize) scripts: https://github.com/TheCharlatan/bitcoin/tree/kernelLinearize
* A silent payment scanner: https://github.com/josibake/silent-payments-scanner
* An electrs index builder: https://github.com/josibake/electrs/commits/electrs-kernel-integration
* A rust bitcoin node: https://github.com/TheCharlatan/kernel-node
* A reindexer: https://github.com/TheCharlatan/bitcoin/tree/kernelApi_Reindexer
The library has also been used by other developers already:
* A historical block analysis tool: https://github.com/ismaelsadeeq/mining-analysis
* A swiftsync hints generator: https://github.com/theStack/swiftsync-hints-gen
* Fast script validation in floresta: https://github.com/vinteumorg/Floresta/pull/456
* A swiftsync node implementation: https://github.com/2140-dev/swiftsync/tree/master/node
Next to the C++ header also made available in this pull request, bindings for other languages are available here:
* Rust: https://github.com/TheCharlatan/rust-bitcoinkernel
* Python: https://github.com/stickies-v/py-bitcoinkernel
* Go: https://github.com/stringintech/go-bitcoinkernel
* Java: https://github.com/yuvicc/java-bitcoinkernel
The rust bindings include unit and fuzz tests for the API.
The header currently exposes logic for enabling the following functionality:
* Feature-parity with the now deprecated libbitcoin-consensus
* Optimized sha256 implementations that were not available to previous users of libbitcoin-consensus thanks to a static kernel context
* Full support for logging as well as control over categories and severity
* Feature parity with the existing experimental bitcoin-chainstate
* Traversing the block index as well as using block index entries for reading block and undo data.
* Running the chainstate in memory
* Reindexing (both full and chainstate-only)
* Interrupting long-running functions
The pull request introduces a new kernel-only test binary that purely relies on the kernel C header and the C++ standard library. This is intentionally done to show its capabilities without relying on other code inside the project. This may be relaxed to include some of the existing utilities, or even be merged into the existing test suite.
The complete docs for the API as well as some usage examples are hosted on [thecharlatan.ch/kernel-docs](https://thecharlatan.ch/kernel-docs/index.html). The docs are generated from the following repository (which also holds the examples): [github.com/TheCharlatan/kernel-docs](https://github.com/TheCharlatan/kernel-docs).
#### How can I review this PR?
Scrutinize the commit messages, run the tests, write your own little applications using the library, let your favorite code sanitizer loose on it, hook it up to your fuzzing infrastructure, profile the difference between the existing bitcoin-chainstate and the bitcoin-chainstate introduced here, be nitty on the documentation, police the C interface, opine on your own API design philosophy.
To get a feeling for the API, read through the tests, or one of the examples.
To configure this PR for making the shared library and the bitcoin-chainstate and test_kernel utilities available:
```
cmake -B build -DBUILD_KERNEL_LIB=ON -DBUILD_UTIL_CHAINSTATE=ON
```
Once compiled the library is part of the build artifacts that can be installed with:
```
cmake --install build
```
#### Why a C header (and not a C++ header)
* Shipping a shared library with a C++ header is hard, because of name mangling and an unstable ABI.
* Mature and well-supported tooling for integrating C exists for nearly every popular language.
* C offers a reasonably stable ABI
Also see https://github.com/bitcoin/bitcoin/pull/30595#issuecomment-2285719575.
#### What about versioning?
The header and library are still experimental and I would expect this to remain so for some time, so best not to worry about versioning yet.
#### Potential future additions
In future, the C header could be expanded to support (some of these have been roughly implemented):
* Handling transactions, block headers, coins cache, utxo set, meta data, and the mempool
* Adapters for an abstract coins store
* Adapters for an abstract block store
* Adapters for an abstract block tree store
* Allocators and buffers for more efficient memory usage
* An "[io-less](https://sans-io.readthedocs.io/how-to-sans-io.html)" interface
* Hooks for an external mempool, or external policy rules
#### Current drawbacks
* For external applications to read the block index of an existing Bitcoin Core node, Bitcoin Core needs to shut down first, since leveldb does not support reading across multiple processes. Other than migrating away from leveldb, there does not seem to be a solution for this problem. Such a migration is implemented in #32427.
* The fatal error handling through the notifications is awkward. This is partly improved through #29642.
* Handling shared pointers in the interfaces is unfortunate. They make ownership and freeing of the resources fuzzy and poison the interfaces with additional types and complexity. However, they seem to be an artifact of the current code that interfaces with the validation engine. The validation engine itself does not seem to make extensive use of these shared pointers.
* If multiple instances of the same type of objects are used, there is no mechanism for distinguishing the log messages produced by each of them. A potential solution is #30342.
* The background leveldb compaction thread may not finish in time leading to a non-clean exit. There seems to be nothing we can do about this, outside of patching leveldb.

This is the main driver class for anything validation related, so expose
it here.
Creating the chainstate manager options will currently also trigger the
creation of their respectively configured directories.
The chainstate manager and block manager options are consolidated into a
single object. The kernel might eventually introduce a separate block
manager object for the purposes of being a light-weight block store
reader.
The chainstate manager will associate with the context with which it was
created for the duration of its lifetime and it keeps it in memory with
a shared pointer.
The tests now also create dedicated temporary directories. This is
similar to the behaviour in the existing unit test framework.

51093d6ae1 test: resolve symlinks in which result for capnp (David Gumberg)
Pull request description:
On Fedora, `/bin/` and `/usr/bin` are symlinked, and on one of my boxes (although I could not reproduce this behavior in a docker container), `/bin` comes before `/usr/bin` in `$PATH`, so `which capnp` reports `/bin/capnp`, and `capnp_dir` is set to `/include`, and the test fails:

66667d6512 test: Use same rpc timeout for authproxy and cli (MarcoFalke)
Pull request description:
It seems odd to use different timeouts (and timeout factors) depending on whether the Python RPC proxy is used, or the bitcoin rpc command line interface.
Fix it by using the same timeout.
This can be tested by introducing a timeout error and checking it happens with and without `--usecli` after the exact same time.
Example timeout error:

57f7c68821 test: add functional test for `TestShell` (matching doc example) (Sebastian Falbesoner)
53874f7934 doc: test: update TestShell example instructions/options (Sebastian Falbesoner)
Pull request description:
This PR adds a functional framework test for the `TestShell` class. The primary motivation for this is to avoid that the example instructions for the interactive Python shell in `test-shell.md` get outdated or broken without noticing, a problem we had already several times in the past (see #26520, #27906, #31415). Having a copy is still not perfect, as docs and functional test have to be kept in sync, but I don't expect this to be a problem in practice, assuming the hint in the functional test comment is hopefully noticed if changes are made.
Alternatively, the example instructions in `test-shell.md` could be removed with a hint to the functional test (I tend to prefer to keep the docs as-is though, showing the full REPL interaction).
The first commit contain two small removal fix-ups in `test-shell.md` regarding the result of the `createwallet` RPC call and the mentioning of the `noshutdown` option that was removed earlier (see #31620). Could be backported to v30.

'warnings': ['Range not given, using default keypool range']},
{'success': True,

```
But in above, ONLY external has a label.
If you remove `internal: False` from external descriptor import object - it will import no problem:
```
[{'success': True,
'warnings': ['Range not given, using default keypool range']},
{'success': True,
'warnings': ['Range not given, using default keypool range']}]
```
Even tho it should NOT, as the descriptor is ranged. Current implementation relies on checking user provided data to decide whether desc is ranged.

Pull request description:
This PR grabs some interesting bits from https://github.com/bitcoin/bitcoin/pull/29284 and fixes some edge cases in how block tiebreaks are dealt with.
## Regarding #29284
The main functionality from the PR was dropped given it was not an issue anymore, however, reviewers pointed out some comments were outdated https://github.com/bitcoin/bitcoin/pull/29284#discussion_r1522023578 (which to my understanding may have led to thinking that there was still an issue) it also added test coverage for the aforementioned case which was already passing on master and is useful to keep.
## New functionality
While reviewing the superseded PR, it was noticed that blocks that are loaded from disk may face a similar issue (check https://github.com/bitcoin/bitcoin/pull/29284#issuecomment-1994317785 for more context).
The issue comes from how tiebreaks for equal work blocks are handled: if two blocks have the same amount of work, the one that is activatable first wins, that is, the one for which we have all its data (and all of its ancestors'). The variable that keeps track of this, within `CBlockIndex` is `nSequenceId`, which is not persisted over restarts. This means that when a node is restarted, all blocks loaded from disk are defaulted the same `nSequenceId`: 0.
Now, when trying to decide what chain is best on loading blocks from disk, the previous tiebreaker rule is not decisive anymore, so the `CBlockIndexWorkComparator` has to default to its last rule: whatever block is loaded first (has a smaller memory address).
This means that if multiple same work tip candidates were available before restarting the node, it could be the case that the selected chain tip after restarting does not match the one before.
Therefore, the way `nSequenceId` is initialized is changed to:
- 0 for blocks that belong to the previously known best chain
- 1 to all other blocks loaded from disk

Pull request description:
### Summary
Users can encounter cases where script checks are unexpectedly enabled (e.g. after reindex, or when `assumevalid`/`minimumchainwork` gates fail). Without an explicit line, they must infer state from the absence of a message, which is incomplete and error-prone.
The existing "Assuming ancestors of block …" line does not reliably indicate whether script checks are actually enabled, which makes debugging/benchmarking confusing.
### What this changes
We make the initial **script-verification** state explicit and log **why** checks are enabled to avoid confusion.
* Always log the first script-verification state on startup, **before** the first `UpdateTip`.
* Flatten the nested `assumevalid` conditionals into a linear gating sequence for readability.
* Extend the functional test to assert the old behavior with the new reason strings.
This is a **logging-only** test change it shouldn't change any other behavior.
### Example output
The state (with reason) is logged at startup and whenever the reason changes, e.g.:
* `Disabling script verification at block #904336 (000000000000000000014106b2082b1a18aaf3091e8b337c6fed110db8c56620).`
* `Enabling script verification at block #912527 (000000000000000000010bb6aa3ecabd7d41738463b6c6621776c2e40dbe738a): block too recent relative to best header.`
* `Enabling script verification at block #912684 (00000000000000000001375cf7b90b2b86e559d05ed92ca764d376702ead3858): block height above assumevalid height.`

fa0dc4bdff test: Allow testing of check failures (MarcoFalke)
faeb58fe66 refactor: Set G_ABORT_ON_FAILED_ASSUME when G_FUZZING_BUILD (MarcoFalke)
Pull request description:
A failing `CHECK_NONFATAL` will throw an exception. This is fine and even desired in production builds, because the program may catch the exception and give the user a way to easily report the bug upstream.
However, in debug development builds, exceptions for internal bugs are problematic:
* The exception could accidentally be caught and silently ignored
* The exception does not include a full stacktrace, possibly making debugging harder
Fix all issues by turning the exception into an abort in debug builds.
This can be tested by reverting the hunks to `src/rpc/node.cpp` and `test/functional/rpc_misc.py` and then running the functional or fuzz tests.

d0e1bbad01 test: repeat block malleability test with relayable block over P2P (Musa Haruna)
Pull request description:
This PR adds a functional test to repeat the existing malleability check for oversized coinbase witness nonce size using a block that is small enough to be relayed over the P2P network.
This addresses the TODO in test_block_malleability by ensuring behavior is consistent between submitblock RPC and P2P relay.

e9cd45e3d3 test: set number of RPC server threads to 2 (furszy)
Pull request description:
The default `-rpcthreads` value spawns 16 HTTP server threads for each node.
Running the functional test suite with default `rpcthreads` can exhaust file
descriptors or hit other resource limits very easily (more when tests are run
in parallel).
Furthermore, having 16 threads is unnecessary since they are mostly idle. We
run RPC calls on a single RPC connection and wait for it result synchronously.
There is (almost) never two RPC calls occurring concurrently.
Because of this, the threads are mostly idle, so we can safely limit the number
of them to two.
Note for reviewers:
I checked this does not introduce any timing regression but would be good
to double-check it on your end too. We could add another thread if needed.
Just the 16 threads default value is too high and unnecessary.

Pull request description:
### Summary
This PR fixes `cachedCoinsUsage` accounting bugs in `CCoinsViewCache` that caused UBSan `unsigned-integer-overflow` violations during testing. The issues stemmed from incorrect decrement timing in `AddCoin()`, unconditional reset in `Flush()` on failure, and incorrect increment in `EmplaceCoinInternalDANGER()` when insertion fails.
### Problems Fixed
**1. `AddCoin()` underflow on exception**
- Previously decremented `cachedCoinsUsage` *before* the `possible_overwrite` validation
- If validation threw, the map entry remained unchanged but counter was decremented
- This corrupted accounting and later caused underflow
- **Impact**: Test-only in current codebase, but unsound accounting that could affect future changes
**2. `Flush()` accounting drift on failure**
- Unconditionally reset `cachedCoinsUsage` to 0, even when `BatchWrite()` failed
- Left the map populated while the counter read zero
- **Impact**: Test-only (production `BatchWrite()` returns `true`), but broke accounting consistency
**3. Cursor redundant usage tracking**
- `CoinsViewCacheCursor::NextAndMaybeErase()` subtracted usage when erasing spent entries
- However, `SpendCoin()` already decremented and cleared the `scriptPubKey`, leaving `DynamicMemoryUsage()` at 0
- **Impact**: Redundant code that obscured actual accounting behavior
**4. `EmplaceCoinInternalDANGER()` double-counting**
- Incremented `cachedCoinsUsage` even when `try_emplace` did not insert (duplicate key)
- Inflated the counter on duplicate attempts
- **Impact**: Mostly test-reachable (AssumeUTXO doesn't overwrite in production), but incorrect accounting
### Testing
To reproduce the historical UBSan failures on the referenced baseline and to verify the fix, run:
```
MAKEJOBS="-j$(nproc)" FILE_ENV="./ci/test/00_setup_env_native_fuzz.sh" ./ci/test_run_all.sh
```
The change was tested with the related unit and fuzz test, and asserted before/after each `cachedCoinsUsage` change (in production code and fuzz) that the calculations are still correct by recalculating them from scratch.

This PR implements MuSig2 signing so that the wallet can receive and spend from imported `musig(0` descriptors.
The libsecp musig module is enabled so that it can be used for all of the MuSig2 cryptography.
Secnonces are handled in a separate class which holds the libsecp secnonce object in a `secure_unique_ptr`. Since secnonces must not be used, this class has no serialization and will only live in memory. A restart of the software will require a restart of the MuSig2 signing process.

Move the `cachedCoinsUsage` subtract in `AddCoin()` to after the `possible_overwrite` check.
Previously a throw before assignment decremented the counter without changing the entry, which corrupted accounting and later underflowed.
In `Flush()`, reset `cachedCoinsUsage` to `0` only when `BatchWrite()` succeeds and `cacheCoins` is actually cleared. In production `BatchWrite()` returns `true`, so this mostly affects tests. On failure, leave the counter unchanged to keep it in sync with the cache.
The existing `Flush()` workaround in fuzzing was also removed now that the source of the problem was fixed, so the fuzzer no longer needs `coins_view_cache.Flush()` to realign `cachedCoinsUsage` after an exception.
Replace the prior `expected_code_path` tracking with direct assertions. The role of the variable was to verify that code execution follows only expected paths, either successful addition, or if it's an exception, the message is verified and checked that overwrite was disallowed.
With these changes the counter stays consistent across success and exception paths, so we can finally remove the `UBSan` suppressions for `CCoinsViewCache` that were masking the issue.
Included a unit test as well, attempting to add a different coin to the same outpoint without allowing overwrites and make sure it throws.
We use `SelfTest()` to validates accounting, and check that the cache remains usable.

We currently use 21 of 32 possible bits for `SCRIPT_VERIFY_*` flags, with open PRs that may use 8 more (#29247, #31989, #32247, #32453). The mutinynet fork that has included many experimental soft fork features is [already reusing bits here](d4a86277ed/src/script/interpreter.h (L175-L195)). Therefore, bump this to 64 bits.
In order to make it easier to update this logic in future, this PR also introduces a dedicated type for the script flags, and disables implicit conversion between that type and the underlying integer type. To make verifying that this change doesn't cause flags to disappear, this PR also resurrects the changes from #28806 so that the script flags that are consensus enforced on each block can be queried via getdeploymentinfo.

dda5228e02 test: set par=2 in default config for functional test framework (Andrew Toth)
Pull request description:
Depending on the host machine, a default `par` value can spawn up to 15 script verification threads for each node. Running the functional test suite with default `par` can exhaust file descriptors or hit other resource limits when many threads are spawned. These threads are mostly idle and the same code paths are executed with a value of `par=2`. Limit this to 2 for functional tests that do not override the default option.

576dd97cb9 test: increase timeout in p2p_leak_tx.py (Martin Zumsande)
Pull request description:
This fixes two issues with `p2p_leak_tx.py`:
1.) #33090: As far as I can see, this is just the randomness of `NextInvToInbounds`/ `rand_exp_duration`, which has a probability of `e^-(60s/5s) = 6.14×10^−6` to result in a period > 60s (our waiting time), so that the test would fail every 160k runs... Doubling the timeout should be sufficient to lower the probability drastically.
2.) The subtest `test_notfound_on_unannounced_tx` has some (w)txid confusion: we send a `MSG_TX`-type getdata with a `wtxid` in it, which necessarily always results in a NOTFOUND. Fixed this, and change the subtest to be more deterministic based on `mocktime`.

Pull request description:
This was the intended behavior but our tests didn't cover the scenario where in-block transactions themselves violate TRUC topological constraints.
The behavior in master will potentially lead to many erroneous evictions during a reorg, where evicted TRUC packages may be very high feerate and make sense to mine all together in the next block and are well within the normal anti-DoS chain limits.

When the assumevalid ancestry check fails, log a precise reason:
- "block height above assumevalid height" if the block is above the assumevalid block (the default reason)
- "block not in of assumevalid chain" otherwise
The new split was added under the existing condition to simplify conceptually that the two cases are related.
It could still be useful to know when the block is just above the assumevalid block or when it's not even on the same chain.
Update the functional test to assert the new reason strings. No behavior change.

After this change, the state is logged before the very first `UpdateTip` line.

Increase the test to 6 nodes and add flows for baseline, deep anchor, and too-recent cases, plus scaffolding for off-best-header, not-in-assumevalid,
and reindex gates.
Assertions are minimal here; follow-ups add reason checks.

451ba9ada4 datacarrier: Undeprecate configuration option (Anthony Towns)
Pull request description:
Removes the deprecation for the `datacarrier` and `datacarriersize` options by reverting commit 0b4048c733 from https://github.com/bitcoin/bitcoin/pull/32406
**Many current Bitcoin Core users want to continue using this option**
This statement is based on public postings from many Bitcoin Core users and not a formal survey. AJ Towns’ observation from [#32406](0b4048c733 (r2084024874)) that “_for now there seem to be a bunch of users who like the option_” has only become more apparent in the months since.
**The deprecation intent is unclear to users**
This echo’s Ava Chow’s comment from #32714 that “_IMO we should not have removal warnings if there is no current plan to actually remove them._” In months since that comment, partially due to increased feedback from Bitcoin Core users wanting to keep this option, there is even less likelihood of a near term plan to remove these options. That leaves Bitcoin Core users in an unclear situation: the option could be removed in the next version or perhaps never. Removing the deprecation gives clarity for their planning purposes. Deprecating the option in the future, preferably with a removal schedule to better inform users, would still be possible.
**Minimal downsides to removing deprecation**
As a best practice, Bitcoin Core has avoided an option when the developers cannot articulate when they should be used. There is non-zero maintenance cost to keeping this code around (although leaving the options deprecated for a long time has the same effect). “Don’t offer users footguns” is also a good principle, but with this option, there seems to be only small impacts that can quickly be remedied by changing the option value by Bitcoin Core users. There already exist in Bitcoin Core more potentially-user-harmful options/values than what datacarrier might cause.

That said, certain users care strongly about using those options. In these conditions, i do not see the project removing the option anytime soon. Therefore i think it's technically incorrect (and confusing) to mark it as deprecated. utACK 451ba9ada4 on removing the deprecation.

fabc2615af test: Use extra_port() helper in feature_bind_extra.py (MarcoFalke)
Pull request description:
This is a refactor for self-validating and self-documenting code.
Currently, the test assumes that extra ports are available and just increments them without checking. However, this may not be the case when the test is modified to use more ports. In this case, the tests may fail intermittently and the failure is hard to debug.
Fix this confusion, by calling `p2p_port` each time. This ensures the required `assert n <= MAX_NODES` is checked each time.
Closes https://github.com/bitcoin/bitcoin/issues/33250

By using mocktime, we will always hit both the notfound
branch and the tx sent branch.
The previous version didn't achieve that due to timing
issues.

With a low but not negligible probability in the order
of 10^-6 the exponential timer NextInvToInBounds can lead
to an interval >60s, making the test fail.
Also uses mocktime to speed up the test and fixes a
non-matching on_inv override.
