a015b7e13d test: Add expected result assertions (yancy)
Pull request description:
~This is a trivial addition to the test suit, however it shouldn't be required to add debug statements and manually run the tests if someone needs to know the results of this test.~
Add an assertion for the values returned. The goal of the test is to show that a minimal weight selection of UTXOs is returned by coin-grinder. Since there are multiple possible solutions, the added assertion shows that coin-grinder finds the solution with the lowest weight. Without this assertion, it's ambiguous whether or not coin-grinder is returning the solution with the lowest weight.
Remove the check that a result is returned since the expected result assertion implies a result.

bf194c920c wallet, rpc: deprecate settxfee and paytxfee (Pol Espinasa)
Pull request description:
**Summary**
This PR deprecates the settxfee RPC and paytxfee setting, marking it for removal in Bitcoin Core 31.0.
**Motivation**
The PR was initially motivated by https://github.com/bitcoin/bitcoin/issues/31088. The intention was to create a new function `settxfeerate` to allow users to set a static fee rate in `sat/vB` instead of `btc/kvB`.
The `settxfee` RPC allows users to set a static fee rate for all transactions created by the wallet. However, in a dynamic fee environment, this can lead to poor fee choices, either overpaying when the mempool is empty or underpaying when congestion is high. The preferred approach is to rely on fee estimation, which is designed to adapt to network conditions, and is the one by default. Same argument apply for `paytxfee` setting.
During discussion the consensus was that static fee settings are a footgun and that users should instead specify the fee rate per transaction if they don't want to rely on the fee estimation. Given this, rather than introducing a `settxfeerate` alternative, this PR goes towards removing `settxfee` and `paytxfee` entirely.
**Key Changes**
`settxfee` and `paytxfee` is now deprecated and will be removed in Bitcoin Core 31.0.
Users should rely on fee estimation or explicitly specify a fee rate when constructing transactions.
**Impact on Users**
If users currently use settxfee or paytxfee, they should transition to specifying fees per transaction.
No immediate breakage in 30.0 (must use `-deprecatedrpc=settxfee`), but `settxfee` and `paytxfee` will be removed in 31.0.
**Alternative Approaches Considered**
A settxfeerate alternative (using sat/vB) was initially proposed but ultimately rejected in favor of deprecating static fee setting entirely.
**Notes for removal**
- When removing paytxfee we should also update txconfirmtarget startup option help text.
- Get back the comment from `rpc_deprecated.py` test. [+info](https://github.com/bitcoin/bitcoin/pull/31278#discussion_r1998876768)

7edaf8b64c Benchmark Chainstate::ConnectBlock duration (Eunovo)
Pull request description:
Introduce benchmarks to evaluate ConnectBlock performance for:
- Blocks containing only Schnorr signatures
- Blocks containing both Schnorr and ECDSA signatures
- Blocks containing only ECDSA signatures
The benchmarks in this PR, focus on signature validation. Additional benchmarks may be added in the future to assess other aspects of ConnectBlock.
This is the first step toward implementing Batch Verification of Schnorr Signatures in Core. It provides a way to test and measure the performance improvements of batch verification on Core.
For more details on batch validation, refer to the [batch-verify module on secp](https://github.com/bitcoin-core/secp256k1/pull/1134) and [batch-verify on core](https://github.com/bitcoin/bitcoin/pull/29491).

Pull request description:
The assumeutxo data for the fuzz target could change and invalidate the hash silently, preventing the fuzz target from reaching some code paths. Fix this by introducing a unit test which would break if the snapshot data the fuzz target relies on were to change.
In implementing this i noticed the height used for coins in the fuzz target is actually off-by-one (as if the first block in the created chain was the genesis but it's block `1`), so fix that too.

Pull request description:
I'm reviewing the Tor controller's reconnect-related code and noticed that the reconnect timeout had no limit. This could lead to excessively long delays.
This PR introduces a maximum reconnect timeout of 600 seconds (10 minutes) to prevent excessive delays in reconnection attempts. It also updates the log message to display the retry delay in whole seconds for better readability.

fa4fb6a8f1 fuzz: Use serial task runner to increase fuzz stability (MarcoFalke)
Pull request description:
Leaking a scheduler with a non-empty queue from the fuzz initialization phase into the fuzz target execution phase is problematic, because it messes with coverage data. This in turn is problematic, because it leads to:
* Decrease in fuzz target execution stability (non-determinism when running the fuzz target).
* Decrease in fuzz input merge stability (non-determinism when selecting a minimum set of fuzz input to reach maximum coverage), which leads to qa-assets bloat.
Fix one such issue. Tracking issue: https://github.com/bitcoin/bitcoin/issues/29018
Can be tested via: `RUST_BACKTRACE=1 cargo run --manifest-path ./contrib/devtools/deterministic-fuzz-coverage/Cargo.toml -- $PWD/bld-cmake $PWD/../b-c-qa-assets/fuzz_corpora/ partially_downloaded_block`.
The failure is non-deterministic (obviously) and will show coverage in validation signals such as `UpdatedBlockTip` before this change and will have this one fixed after this change.

Pull request description:
`Span` has some issues:
* It does not support fixed-size spans, which are available through `std::span`.
* It is confusing to have it available and in use at the same time with `std::span`.
* It does not obey the standard library iterator build hardening flags. See https://github.com/bitcoin/bitcoin/issues/31272 for a discussion. For example, this allows to catch issues like the one fixed in commit fabeca3458.
Both types are type-safe and can even implicitly convert into each other in most contexts.
However, exclusively using `std::span` seems less confusing, so do it here with a scripted-diff.

The changes `outpoints_value` from a map to an unordered map, which is safe, because the element order is not used in the fuzz test and the map is only used for lookup.
(`mempool_outpoints` can't be changed, because the order matters here. Using unordered_set here may result in a non-deterministic fuzz target, given the same fuzz input.)

Also see https://issues.chromium.org/issues/388068052, although note that they [reverted the roll to latest leveldb](https://issues.chromium.org/issues/388068052#comment9). I'm guessing due to the acidental reversion issue above.

Pull request description:
Currently, we successfully parse descriptors which contains spaces in the beginning or end of the public/private key within a fragment (e.g. `pk( KEY)`, `pk(KEY )` or `pk( KEY )`). I have noticed that one of the reasons is that the `DecodeBase58` function simply ignore these whitespaces.
This PR changes the `ParsePubkeyInner ` to reject pubkeys that contain a whitespace at the beginning and/or at the end. We will only check the whitespace in some RPCs (e.g. `importdescriptors`), but an already imported descriptor won't be affected by this check, especially because we store descriptors from `ToString`.

54e6eacc1f test: Enable ResetCoverageCounters beyond Linux (janb84)
Pull request description:
In PR [#31901](https://github.com/bitcoin/bitcoin/pull/31901), Coverage.cpp was introduced as a separate utility file, based on existing code. However, the macro defined in Coverage.cpp was limited to Clang and Linux, which caused issues for users on macOS when using the newly introduced deterministic test tooling.
This change adds fallback functions which are used when building without code coverage on non linux env.
This adds support for macOS to ResetCoverageCounters. ResetCoverageCounters is used by the unit tests in `g_rng_temp_path_init` to support the deterministic unit test tooling. It is also used in fuzz tests to completely suppress coverage from anything init-related.
See [Readme](https://github.com/bitcoin/bitcoin/blob/master/contrib/devtools/README.md) on how to test this for deterministic unit & fuzz test.
Suggestion for test files:
- for unit test: `util_string_tests`
- for fuzz test: `addition_overflow `
These files should give deterministic results

The `_t` and `_v` helper alias templates offer a more concise way to extract the type and value directly.
I've modified the instances I found in the codebase one-by-one (noticed them while investigating https://github.com/bitcoin/bitcoin/pull/31868), and afterwards extracted scripted diff commits to do the trivial ones automatically.

d5537c18a9 fuzz: make sure DecodeBase58(Check) is called with valid values more often (Lőrinc)
bad1433ef2 fuzz: Always restrict base conversion input lengths (Lőrinc)
Pull request description:
This is a follow-up to https://github.com/bitcoin/bitcoin/pull/30746, expanding coverage by:
* restricting every input for the base58 conversions, capping max sizes to `100` instead of `1000` or all available input (suggested by marcofleon in https://github.com/bitcoin/bitcoin/pull/30746#discussion_r1963718683) since most actual usage has lengths of e.g. `21`, `34`, `78`.
* providing more valid values to the decoder (suggested by maflcko in https://github.com/bitcoin/bitcoin/pull/30746#discussion_r1957847712) by randomly providing a random input or a valid encoded one; this also enables unifying the roundtrip tests to a single roundtrip per fuzz.

11f8ab140f test: wallet, coverage for crash on dup block disconnection during unclean shutdown (Martin Zumsande)
9ef429b6ae wallet: fix crash on double block disconnection (furszy)
Pull request description:
The wallet crashes if it processes the same block disconnection event twice in a row due
to an incompatible coinbase transaction state.
This happens because `disconnectBlock` provides `TxStateInactive` without the "abandoned"
flag for coinbase transactions to `SyncTransaction`, while `AddToWallet()` internally modifies
it to retain the abandoned state.
The crash flow is as follows:
1) On the first disconnection, the transaction state transitions from "confirmed" to
"inactive," bypassing the state equality check since the provided state differs. Then,
`AddToWallet` internally updates the state to "inactive + abandoned"
2) On the second disconnection, as we provide only the "inactive" state
to `SyncTransaction()`, the state equality assertion fails and crashes the wallet.
Reviewers Note:
The crash can easily be replicated by cherry-picking the test commit in master.

for consistency with the other CLI commands (-netinfo, -addrinfo, -generate).
This can be considered a bugfix because IsArgSet() returns whether an arg has
been set even if it has been negated. After this change, we no longer treat
-nogetinfo and -getinfo=0 the same as -getinfo and -getinfo=1, and instead as if
-getinfo was not specified.

18e83534ac wallet: Replace "non-0" with "non-zero" in translatable error message (Hennadii Stepanov)
Pull request description:
Transifex interprets the "-0" substring as a number in translatable strings. Since not all translations preserve "-0," this triggers a corresponding warning. While this warning could be disabled globally, it is more reasonable to adjust the original string instead.

cadbd4137d miner: have waitNext return after 20 min on testnet (Sjors Provoost)
d4020f502a Add waitNext() to BlockTemplate interface (Sjors Provoost)
Pull request description:
This PR introduces `waitNext()`. It waits for either the tip to update or for fees at the top of the mempool to rise sufficiently. It then returns a new template, with which the caller can rinse and repeat.
On testnet3 and testnet4 the difficulty drops after 20 minutes, so the second ensures that a new template is returned in that case.
Alternative approach to #31003, suggested in https://github.com/bitcoin/bitcoin/issues/31109#issuecomment-2451942362

GCC 14.2.1 will complain about a dangling reference after replacing Span
wiht std::span. This is a false-positive, because std::find does not
return a reference.
Remove the `&` to silence the warning. Also use ranges::find while
touching the line.

cc1plus: all warnings being treated as errors
Historically, the headers have been bumped some time after a file has
been touched. Do it now to avoid having to touch them again in the
future for that reason.

This uses a macro, which can be a bit more brittle than an alias
template. However, class template argument deduction for alias templates
is only implemented in clang-19.
* The comment is wrong claiming that void* was returned when void was
returned in reality.
* The namespace is missing a name, leading to compile errors that are
suppressed with non-standard pragmas, and leading to compile errors in
future commits. Instead of using more non-standard suppressions, just
add the missing name.
* The SpanableYes/No types are missing begin/end iterators, which will
be needed when using std::span.
In theory this commit should only touch the span.h header, because
std::span can implicilty convert into Span in most places, if needed.
However, at least when using the clang compiler, there are some
false-positive lifetimebound warnings and some implicit conversions can
not be resolved.
Thus, this refactoring commit also changed the affected places to
replace Span with std::span.
Require that sqlite is available in order to compile the wallet. Removes
instances of USE_SQLITE since it is no longer possible to not have
sqlite available.
The NO_SQLITE option is dropped from depends.

e637dc2c01 refactor: Replace uint256 type with Wtxid in PackageMempoolAcceptResult struct (marcofleon)
a3baead7cb validation: use wtxid instead of txid in CheckEphemeralSpends (marcofleon)
Pull request description:
This PR addresses a small bug in [`AcceptMultipleTransactions`](45719390a1/src/validation.cpp (L1598)) where a txid was being inserted into a map that should only hold wtxids. `CheckEphemeralSpends` has an out parameter on failure that records that the child transaction did not spend the parent's dust. Instead of using the txid of this child, use its wtxid.
The second commit in this PR is a refactor of the `PackageMempoolAcceptResult` struct to use the `Wtxid` type instead of `uint256`. This helps to prevent errors like this in the future.

568fcdddae scripted-diff: Adjust documentation per top-level target output location (Hennadii Stepanov)
026bb226e9 cmake: Set top-level target output locations (Hennadii Stepanov)
Pull request description:
This PR sets the target output locations to the `bin` and `lib` subdirectories within the build tree, creating a directory structure that mirrors that of the installed targets.
This approach is widely adopted by the large projects, such as [LLVM](e146c1867e/lldb/cmake/modules/LLDBStandalone.cmake (L128-L130)):
```cmake
set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib${LLVM_LIBDIR_SUFFIX})
```
The `libsecp256k1` project has also recently [adopted](https://github.com/bitcoin-core/secp256k1/pull/1553) this approach.
With this PR, all binaries are conveniently located. For example, run:
```
$ ./build/bin/fuzz
```
instead of:
```
$ ./build/src/test/fuzz/fuzz
```
On Windows, all required DLLs are now located in the same directory as the executables, allowing to run `bitcoin-chainstate.exe` (which loads `bitcoinkernel.dll`) without the need to copy DLLs or modify the `PATH` variable.
The idea was briefly discussed among the build team during the recent CoreDev meeting.
---
**Warning**: This PR changes build locations of newly built executables like `bitcoind` and `test_bitcoin` from `src/` to `bin/` without deleting previously built executables. A clean build is recommended to avoid accidentally running old binaries.

ryanofsky:
Code review ACK 568fcdddae. Only change since last review was rebasing. I'm ok with this PR in its current form if other developers are happy with it. I just personally think it is inappropriate to \*silently\* break an everyday developer workflow like `git pull; make bitcoind`. I wouldn't have a problem with this PR if it triggered an explicit error, or if the problem was limited to less common workflows like changing cmake options in an existing build.
