to expose it directly in the header.
Also move CDBBatch::Clear to the dbwrapper implementation to use the new
impl_batch.

file from leveldb includes. To this end, the includes are moved to the

06199a995f refactor: Revert addition of univalue sighash string check (TheCharlatan)
0b47c16215 doc: Correct release-notes for sighashtype exceptions (TheCharlatan)
Pull request description:
This is a follow up for #28113.
The string type check is already done by the rpc parser / RPCHelpMan. Re-doing it is adding dead code. Instead, throwing an exception when the assumption does not hold is the already correct behavior. Pointed out in this [comment](https://github.com/bitcoin/bitcoin/pull/28113/files#r1274568557).
Also correct the release note for the correct sighashtype exception change. There is no change in the handling of non-string sighashtype arugments. Pointed out in this [comment](https://github.com/bitcoin/bitcoin/pull/28113/files#r1274567555).

Pull request description:
The helpers are unused outside of tests and redundant with the existing `bool read(std::string_view raw);`.
Fix both issues by removing them.
Also, simplify the tests code by removing a `std::string` constructor where possible.

131314b62e fuzz: increase coverage of the descriptor targets (Antoine Poinsot)
90a24741e7 fuzz: add a new, more efficient, descriptor parsing target (Antoine Poinsot)
d60229ede5 fuzz: make the parsed descriptor testing into a function (Antoine Poinsot)
Pull request description:
The current descriptor parsing fuzz target requires valid public or private keys to be provided. This is unnecessary as we are only interested in fuzzing the descriptor parsing logic here (other targets are focused on fuzzing keys serializations). And it's pretty inefficient, especially for formats that need a checksum (`xpub`, `xprv`, WIF).
This introduces a new target that mocks the keys as an index in a list of precomputed keys. Keys are represented as 2 hex characters in the descriptor. The key type (private, public, extended, ..) is deterministically based on this one-byte value. Keys are deterministically generated at target initialization. This is much more efficient and also largely reduces the size of the seeds.
TL;DR: for instance instead of requiring the fuzzer to generate a `pk(xpub6DdBu7pBoyf7RjnUVhg8y6LFCfca2QAGJ39FcsgXM52Pg7eejUHLBJn4gNMey5dacyt4AjvKzdTQiuLfRdK8rSzyqZPJmNAcYZ9kVVEz4kj)` to parse a valid descriptor, it just needs to generate a `pk(03)`.
Note we only mock the keys themselves, not the entire descriptor key expression. As we want to fuzz the real code that parses the rest of the key expression (origin, derivation paths, ..).
This is a target i used for reviewing #17190 and #27255, and figured it was worth PR'ing on its own since the added complexity for mocking the keys is minimal and it could help prevent introducing bugs to the descriptor parsing logic much more efficiently.

08eb5f1b67 ci: document that -Wreturn-type has been fixed upstream (Windows) (fanquake)
Pull request description:
`noreturn` attributes have been added to the mingw-w64 headers, 1690994f51, meaning that [from 11.0.0 onwards](https://www.mingw-w64.org/changelog/), you'll no-longer see `-Wreturn-type` warnings when using `assert(false)`.
Add -Wno-return-type to the Windows CI, where is should have been all
along, and document why it's required. This can be dropped when we are
using the fixed version of the mingw-w64 headers there.
Drop the -Werror -Wno-return-type special case from our build system.
-Wreturn-type is on by default in Clang and GCC.
The new mingw-w64 header behaviour can be checked on Ubuntu mantic, [which ships with 11.0.0](https://packages.ubuntu.com/mantic/mingw-w64), using:
```cpp
#include <cassert>
int f(){ assert(false); }
int main() {
return 0;
}
```
On Mantic (with 11.0.0):
```bash
x86_64-w64-mingw32-g++ test.cpp -Wreturn-type
# nada
```
On Lunar ([with 10.0.0](https://packages.ubuntu.com/lunar/mingw-w64)):
```bash
x86_64-w64-mingw32-g++ test.cpp -Wreturn-type
test.cpp: In function 'int f()':
test.cpp:3:25: warning: no return statement in function returning non-void [-Wreturn-type]

This check is already done by the rpc parser. Re-doing it is adding dead
code. Instead, throwing an exception when the assumption does not hold
is the already correct behavior.
To make the fuzz test more accurate and not swallow all runtime errors,
add a check that the passed in UniValue sighash argument is either a
string or null.

In `wallet_fundrawtransaction`, `totalOut` is used in
some functions to check if the change is correct. In
other ones, it has been created but never used.
fa9108f85a refactor: Use reinterpret_cast where appropriate (MarcoFalke)
3333f950d4 refactor: Avoid casting away constness (MarcoFalke)
fa6394dd10 refactor: Remove unused C-style casts (MarcoFalke)
Pull request description:
Using a C-style cast to convert pointer types to a byte-like pointer type has many issues:
* It may accidentally and silently throw away `const`.
* It forces reviewers to check that it doesn't accidentally throw away `const`.
For example, on current master a `const char*` is cast to `unsigned char*` (without `const`), see d23fda0584/src/span.h (L273) . This can lead to UB, and the only reason why it didn't lead to UB is because the return type added back the `const`. (Obviously this would break if the return type was deduced via `auto`)
Fix all issues by adding back the `const` and using `reinterpret_cast` where appropriate.

c648bdbda2 test: create wallet specific for test_locked_wallet case (furszy)
Pull request description:
Coming from https://github.com/bitcoin/bitcoin/pull/28089#discussion_r1265478128.
Several test cases are relying on the node1 default wallet, which thanks to 'test_locked_wallet' is encrypted.
And can be only accessed within a specific timeframe (100ms), a duration internally set by the same test.
This situation introduces a potential race condition, where other tests must complete their operations within
the specified 100ms window to pass (otherwise the wallet gets re-locked and they fail).
This can be seen running the test in valgrind (https://github.com/bitcoin/bitcoin/pull/28089), where other test cases fail due the wallet re-locking
itself after the 100ms.

53c990ad34 test: fix `feature_addrman.py` on big-endian systems (Sebastian Falbesoner)
Pull request description:
The test `feature_addrman.py` currently serializes the addrdb without specifying endianness for `int`s, so the machine's native byte order is used (see https://docs.python.org/3/library/struct.html#byte-order-size-and-alignment) and the generated `peers.dat` would be invalid on big-endian systems (our internal (de)serializers always use little-endian, see `ser_{read,write}data32`). Fix this by explicitly specifying little-endian serialization via the `<` character in `struct.pack(...)`.
This is not detected by CI as we unfortunately don't run functional tests on big-endian systems there (I think we definitely should!).

Affects both secure_allocator and zero_after_free_allocator.
Giving the C++ Standard Committee control of the public interface of your type means they will break it. C++23 adds a new `allocate_at_least` member to `std::allocator`. Very bad things happen when, say, `std::vector` uses `allocate_at_least` from `secure_allocator`'s base to allocate memory which it then tries to free with `secure_allocator::deallocate`.
Drive-by: Aggressively remove facilities unnecessary since C++11 from both allocators to keep things simple.
Other tests are also relying on the node1 default wallet,
which thanks to 'test_locked_wallet' is encrypted.
And can only be accessed within a specific timeframe (100ms)
set internally by the same test.
This make other tests susceptible to races. They can only
perform their operations successfully within the specified
time.
This can be seen running the test in valgrind, where other
test cases fail due the wallet re-locking itself after the
100ms.
Once a descriptor is successfully parsed, execute more of its methods.
There is probably still room for improvements by checking for some
invariants, but this is a low hanging fruit that significantly increases
the code coverage of these targets.
This new target focuses on fuzzing the actual descriptor parsing logic
by not requiring the fuzzer to produce valid keys (nor a valid checksum
for that matter).
This should make it much more efficient to find bugs we could introduce
moving forward.
Using a character as a marker (here '%') to be able to search and
replace in the string without having to mock the actual descriptor
parsing logic was an insight from Pieter Wuille.
