2bb6ab8f1b ci: Add "Get bitcoind manifest" steps to Windows CI jobs (Hennadii Stepanov)
282b4913c7 cmake: Add application manifests when cross-compiling for Windows (Hennadii Stepanov)
Pull request description:
Windows [application manifests ](https://learn.microsoft.com/en-us/windows/win32/sbscs/application-manifests) provide several benefits—such as enhanced security settings, and the ability to set a process-wide code page (required for https://github.com/bitcoin/bitcoin/pull/32380), as well as granular control over supported Windows versions. Most of these benefits lie beyond the scope of this PR and will be evaluated separately.
On the current master branch @ fc6346dbc8, the linker generates and embeds a manifest only when building with MSVC:
```xml
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
<security>
<requestedPrivileges>
<requestedExecutionLevel level="asInvoker" uiAccess="false"></requestedExecutionLevel>
</requestedPrivileges>
</security>
</trustInfo>
</assembly>
```
However, this manifest fails validation:
```
> mt.exe -nologo -inputresource:build\bin\Release\bitcoind.exe -validate_manifest
mt.exe : general error 10100ba: The manifest is missing the definition identity.
```
This PR unifies manifest embedding for both native and cross-compilation builds.
Here is the change in the manifest on Windows:
```diff
--- bitcoind-master.manifest
+++ bitcoind-pr.manifest
@@ -1,5 +1,6 @@
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<assembly xmlns="urn:schemas-microsoft-com:asm.v1" manifestVersion="1.0">
+ <assemblyIdentity type="win32" name="org.bitcoincore.bitcoind" version="29.99.0.0"></assemblyIdentity>
<trustInfo xmlns="urn:schemas-microsoft-com:asm.v3">
<security>
<requestedPrivileges>
```
which effectively resolves the "missing the definition identity" error.
Finally, “Get bitcoind manifest” steps have been added to the Windows CI jobs to ensure the manifest is embedded and validated.

This reverts commit b2d5361002.
Also, adjust the doc to reflect the new minimum version. Versions 17.6
or 17.11 (or anything in between) may still work on a best-effor basis,
but it is not checked by CI or by developers.
It is only used in test. There it is problematic, because it sometimes
relies on m_default_address_type. If the default were changed to
BECH32M, those tests would fail the assert(false).
So just use PKHash{} in all tests and remove GetDestinationForKey.
Windows application manifests provide several benefits. However, on the
master branch, the linker generates and embeds manifests only when
building with MSVC.
This change unifies manifest embedding for both native and

> Currently, RunCommandParseJSON runs its target with whatever fds happen to be open inherited on POSIX platforms. I don't think there's any practical scenario where this is a problem right now, but there's a lot of potential for weird problems (eg, if a process manages to outlive bitcoind - perhaps it's hanging - the listening port(s) won't get released and starting bitcoind again will fail). It's also a potential security issue if a child process is intended to be sandboxed at some point. Not to mention plain ugly :)

> cpp-subprocess has a feature to address this called close_fds. Not sure why it was removed in https://github.com/bitcoin/bitcoin/pull/29961 rather than fixing this during the migration, but this PR restores it, enables it for RunCommandParseJSON, and optimises it by iterating over /proc/self/fd/ like most other libraries do these days ([eg, glib]> (487b1fd20c/glib/gspawn.c (L1094))) since iterating all possible fd numbers [has been found to be problematic](https://bugzilla.redhat.com/show_bug.cgi?id=1537564).

When an expression J that has integral type is added to [...] an

So remove them, along with the ubsan suppressions, that are no longer used.
I've tagged this a refactor, because the code was always dead (unused outside of tests). And since commit 2925bd537c it was completely dead. Also, I could not find a sanitizer that detects this type of UB.

02d4bc776b interfaces: remove redundant coinbase fee check in `waitNext` (ismaelsadeeq)
Pull request description:
#### Motivation
In [Internal interface guidelines](https://github.com/bitcoin/bitcoin/blob/master/doc/developer-notes.md#internal-interface-guidelines)
It's stated that
> Interface method definitions should wrap existing functionality instead of implementing new functionality. Any substantial new node or wallet functionality should be implemented in [src/node/](https://github.com/bitcoin/bitcoin/blob/master/src/node) or [src/wallet/](https://github.com/bitcoin/bitcoin/blob/master/src/wallet) and just exposed in [src/interfaces/](https://github.com/bitcoin/bitcoin/blob/master/src/interfaces) instead of being implemented there, so it can be more modular and accessible to unit tests.
However the some methods in the newly added `BlockTemplateImpl` and `MinerImpl` classes partially enforces this guideline, as the implementations of the `submitSolution`, `waitNext`, and `waitTipChanged` methods reside within the class itself.
#### What the PR Does
This PR introduces a simple refactor by moving certain method implementations from `BlockTemplateImpl` into the miner module. It introduces three new functions:
1. Remove rundundant coinbase fee check in `waitNext`
2. **`AddMerkleRootAndCoinbase`**: Computes the block's Merkle root, inserts the coinbase transaction, and sets the Merkle root in the block. This function is called by `submitSolution` before the block is submitted for processing.
3. **`WaitAndCreateNewBlock`**: Returns a new block template either when transaction fees reach a certain threshold or when a new tip is detected. If a timeout is reached, it returns `nullptr`. The `waitNext` method in `BlockTemplateImpl` now simply wraps this function.
4. Move `GetTip` implementation to miner.
5. **`WaitTipChanged`**: Returns the tip when the chain it changes, or `nullopt` if a timeout or interrupt occurs. The `waitTipChanged` method in `MinerImpl` now calls `GetTip` after invoking `ChainTipChanged`, and returns the tip.
#### Behavior Change
- We now only `Assert` for a valid chainman and notifications pointer once.

Made every signed/unsigned conversion in the serialization helpers explicit so the UBSan `implicit-sign-change` check passes and the `serialize.h` suppression can be dropped.
For consistency, a few other simple changes were also applied to the serialization helpers:
* remove redundant `inline` on function templates;
* unify formatting to make the differences between similar methods obvious.
- This commit creates a function `WaitTipChanged` that waits for the connected
tip to change until timeout elapsed.
- This function is now used by `waitTipChanged`

fa427ffcee fuzz: Properly setup wallet in wallet_fees target (MarcoFalke)
Pull request description:
`g_wallet_ptr` is destructed after the `testing_setup`. This is not supported and will lead to issues such as https://github.com/bitcoin/bitcoin/pull/30221#issuecomment-2863875857 or https://github.com/bitcoin/bitcoin/pull/32409#issuecomment-2855259932.
This could be fixed by fixing the initialization order.
However, the global wallet is also modified in the fuzz target, which is bad fuzzing practise.
So instead fix it by constructing a fresh wallet for each fuzz iteration.

1e0de7a6ba fees: document non-monotonic estimation edge case (willcl-ark)
Pull request description:
Closes: https://github.com/bitcoin/bitcoin/issues/11800
In scenarios where data is available for higher targets but not for lower ones, this method *may* return lower fee rates for higher confirmation targets. This could occur if `estimateCombinedFee` returns no valid data (`-1`) for some estimates for a low target, but **does** return valid data for a higher target.
Users of this function should be aware of this potential, if unlikely, inconsistency in behaviour in data-sparse scenarios.

0750249289 mining: document gbt_rule_value helper (Sjors Provoost)
5e87c3ec09 scripted-diff: rename gbt_force and gbt_force_name (Sjors Provoost)
Pull request description:
The term "force" is ambiguous and not used in [BIP9](https://github.com/bitcoin/bips/blob/master/bip-0009.mediawiki#getblocktemplate-changes) where there ! rule prefix is introduced.
E.g. this code is hard to read:
```cpp
if (!gbt_force) {
s.insert(s.begin(), '!');
```
Additionally, #29039 renamed `gbt_vb_name` to `gbt_force_name` which, at least for me, further increased the confusion.
This is a pure (variable rename) refactor (plus documentation) and does not change behavior.
