💬 Sjors commented on pull request "Stratum v2 Template Provider (take 2)":
(https://github.com/bitcoin/bitcoin/pull/28983#issuecomment-1853542223)
It's not easy being green, but including `compat.h` should fix the issue:

```cpp
// ssize_t is POSIX, and not present when using MSVC.
```

The CI fuzzer caught an overflow, so I added a guard against absurd `coinbase_output_max_additional_size` values. I have not tried the fuzzer myself yet, nor does it have complete coverage, so there may still be other issues.

See https://github.com/bitcoin/bitcoin/issues/28918#issuecomment-1853532671. This doesn't seem to have fixed the fuzzer.

Ok the lazy way clearly doesn't work; I think what we have to do is calculate in-package ancestors and feed that to `ApplyV3Rules` when we call it. This will also have the effect of consolidating our v3 checks so that it's cleaner. Pushing soon...

@conduition thanks for writing that article, it's a very interesting read but I still feel we are not on the same page yet.

The point of "fighting the spam TXs" is not to prevent all forms of data inscription at all costs, it's to fix Bitcoin's fee market.

> Let's at least let builders explicitly enable it?

That would mostly defeat the point of this change, and leave us supporting code that we've deemed unsafe and unreviewed. If someone wants to do that, they are free to understand the risks, and patch their own code.

📝 maflcko opened a pull request: "refactor: Remove Span operator==, Use std::ranges::equal"
(https://github.com/bitcoin/bitcoin/pull/29071)
`std::span` removed the comparison operators, so it makes sense to remove them for the `Span` "backport" as well. Using `std::ranges::equal` also has the benefit that some `Span` temporary constructions can now be dropped.
