(https://github.com/bitcoin/bitcoin/pull/30828)

This PR addresses the remaining review comments from #30697

1. Disallowed overwriting settings values with a `null` value.
2. Uniformly used the `SettingsAction` enum in all settings methods instead of a boolean parameter.
3. Updated `overwriteRwSetting` to receive the `common::SettingsValue` parameter by value, enabling it to be moved safely.
4. Removed wallet context from the `write_wallet_settings_concurrently` unit test, as it is not needed.

I've tested this locally by passing an unknown settings name this does not throw.

Agreed, I see no reason for allowing a null value.
Removed in #30828

Thanks for your reviews, @stickies-v and @ryanofsky.
I've addressed the review comments in #30828.


> Thanks. I think a natural cleanup or follow-up to this PR could involve moving the `interfaces::Node` settings methods (`isSettingIgnored`, `getPersistentSetting`, `updateRwSetting`, `forceSetting`, and `resetSettings`) and the `interfaces::Chain` settings methods (`getSetting`, `getSettingList`, `getRwSetting`, `updateRwSetting`, `overwriteRwSetting`, `deleteRwSettings`) into a new `inte

Might be better as something like:

```python
signet_spk = tmpl["signet_challenge"]
if trivial_challenge(signet_spk):
signet_solution = None:
else:
...
```

and

```
def trivial_challenge(spkhex):
"""BIP325 allows ..."""
if spkhex == "51":
return True
return False
```

`OP_RETURN` ?

Better to move `def generate_psbt(..)` down to its code, rather than moving the code up?

💬 ajtowns commented on pull request "signet: fixing mining for OP_TRUE challenge":
(https://github.com/bitcoin/bitcoin/pull/29032#discussion_r1746299406)
nit: I'd probably write this as

```python
if signet_solution is None:
pass # Don't need to add a signet commitment if there's no signet signature needed
else:
...
```

💬 ajtowns commented on pull request "signet: fixing mining for OP_TRUE challenge":

Does it still make sense to grab the `block` from `decode_psbt` here? You already passed it in to `generate_psbt`. Could just be `_, signet_solution = decode_psbt(...)`, or perhaps have separate functions `get_solution_from_psbt()` and `get_block_from_psbt()` ?

> Using real mining equipment as opposed to a CPU miner is useful, because of the many quirks real devices have (e.g. version bit grinding). Afaik there's no good emulator.

FWIW, I did a patch for bitcoin-util to do version bit grinding: https://github.com/ajtowns/bitcoin/commit/634e72cbfc0aa3f657a35c7b597f688bb2bb29a6 (Note that it lightly depends on the changes in #28802)

Nice benchmarks, any value in running them on the removed optimizations?

> clusterlin: avoid jump ahead in unmodified pot sets (optimization)


Any idea why LinearizeSerializedCluster5 is an outlier now? It separates from the rest at "improve heuristic to decide split transaction".

Done, pushed new ones, and moved the commit that introduces them forward to the point where they make sense.

@gmaxwell I've just pushed a new set of example benchmark clusters, with the property that they need between 100k and 1M iterations to linearize optimally sometimes and never more than 10M iterations. I'm not well set up right now to benchmark, but at the end of this PR, I see:
