`BOOST_CHECK(result_b->GetAlgoCompleted() == false);` right after the `BOOST_CHECK(!result_b);`.

I guess that might prove TOTAL_TRIES has been hit, instead of failing for any other reason. It obviously doesn’t give a typed error enum(like the rust version), but I guess it is the best that can be done with the current C++ API without a larger refactor. ?

Thanks! Adjusted.

📝 Sjors opened a pull request: "mining: add getCoinbase()"
(https://github.com/bitcoin/bitcoin/pull/33819)
Deprecate `getCoinbaseTx()` in favor of a new method that provides a struct with everything clients need to construct a coinbase. This is safer than providing a raw dummy coinbase that clients then have to manipulate.

Also deprecate `getCoinbaseCommitment()` and `getWitnessCommitmentIndex()`.

A new helper method `ExtractCoinbaseTemplate()` processes the dummy coinbase transaction generated by `BlockAssembler::CreateNewBlock` and produces a `CoinbaseTemplate`.

> This is done to align the method with PSBT. It could be removed without breaking the change. But it also is just clearing data which should take minimal time. I think it's worth keeping to align with PSBT format.

I don't fully understand how it is aligning with PSBT, can you please explain? `GetHash()` used both here later and in `combinePSBT` RPC doesn't take the witness into account, making the removal of witness unnecessary.

I would mention that if any other test imports `capnp` in the future without adding the specific logic `interface_ipc.py`, then it will run into the same issue. But I think this makes sense for now

💬 Sjors commented on issue "Mining interface tracking issue":
(https://github.com/bitcoin/bitcoin/issues/33777#issuecomment-3502947184)
@ismaelsadeeq I'm think about deprecating `getBlock()` in favour of a new `getTransactions()`. That would allow us to avoid shoehorning block templates in `CBlock`, which e.g. means we no longer need a dummy coinbase transaction.

Would it make sense to add a TODO to remove the warning suppression once GIL is supported in the capnp library?

Won't old versions be able to read the file even if estimations are sub 1sat/vb?

Yes it is necessary, old clients won't be able to read the file saved with new client, and new client won't also be able to read the file saved by old client see https://github.com/bitcoin/bitcoin/pull/33199#issuecomment-3242381132 comment with a linked PR that allows for that approach.

I am doing a breaking change here so I deleted it because it is indeed dummy and unused.
But you are right it is unrelated.
I add it in a separate commit.

Given [sv2-tp](https://github.com/stratum-mining/sv2-tp) and a few others are the users of this interface and they are still in development.

I'd rather have any un-useful methods pruned.
When we release a stable interface then we can start deprecating things to avoid breaking clients (As you mentioned in the tracking issue it is okay to make breaking changes so all these methods should be pruned and clients should update).
