Makes sense. utACK 7180b82420c0f303140a93ca635f5ac806bea77d. Could add a comment explaining this to the test as it may not be immediately obvious to a reader.

Thanks for fixing it - someone with more knowledge in this area should also validate it.

nit: the leading space was deliberate, it's used in other sentences as well to signal that it's a continuation.
We can either keep this style or remove it from this block comment, but only removing it on this line only is inconsistent. For simplicity and diff minimization I'd just revert this line.

could we do this change in a separate commit, explaining in the commit messages separately why this needed?
And I might be wrong here but I don't understand why we need to run this twice - which is the case for reindex as far as I can tell.

I think we are crossing wires here. I was talking about running coin selection with the **same UTXO set** at two different feerates. You appear to be talking about running a test with two different UTXO sets generated from the same set of _effective values_ at different feerates.

The test you propose is also interesting, and someone might want to take a stab at adding it in another pull request. It is out of scope for this pull request however.

Fuzzing explores pseudorandomly all code paths that can be reached by exercising the fuzz harness. By comparing BnB with a brute force search, we can demonstrate that BnB always finds the best solution that is present, but only when they are present. As only inputs that cause new paths to be explored in the source code are reta

I wonder if it wouldn't be simpler if all of the `m_block_xyz` class members were just local variables within `CoinStatsIndex::CustomAppend` instead.
The previous values are being overwritten here with each new block, and as far as I can see the saved values (while being set to correct values in `CustomInit` and `ReverseBlock`) are not used anywhere - except for

Code review ACK 56b1da77b5998c44b3bb799689a6c0449e9223fc. Thanks for the update! The fix here seems right and should be practically useful. And the new tests seem to cover different scenarios where positional string parameters contain '='.

Two comments:

- I think it would good to add a test to cover cases where positional *non-string* parameters contain '=', i.e. the `bitcoin-cli -named echojson '["fail=yes"]'` case which [previously failed](https://github.com/bitcoin/bitcoin/pull/32821#di

Note: this comment is not exactly describing what is happening during this test. It's not true in general that unknown parameters with `=` are treated as positional. Unknown parameters with `=` are only treated as positional if the next positional parameter is known and either accepts a string (this case) or if it's known and accepts JSON and the argument actually parses as json.

Not sure the names `is_string_method` and `is_convert_method` are really accurate here. `is_string_method` is true if the method's next positional argument expects a string, and `is_convert_method` is true if it expects a non-string value. Could maybe consider calling them `next_positional_arg_is_string` or `next_positional_arg_is_json` or something like that. Code looks li

What is the step to reproduce your result?

Side note to self could be useful to try benchmarking this using [benchkit](https://github.com/bitcoin-dev-tools/benchkit) so that anyone can reproduce using the yaml config?
