eth, miner: remove duplicated code by rjl493456442 · Pull Request #23256 · ethereum/go-ethereum

rjl493456442 · 2021-07-23T06:25:17Z

This PR removes the duplicated code in the catalyst package, reuse the miner package code instead.

Highlight the critical changes in this PR:

Offer one more API in the miner package called GetSealingBlock which will assemble and return the sealing block based on the given parameters.
Sealing environment is abstracted out, all the functions will receive the sealing environment for further operations
Uncle blocks management is changed for sake of simplification

holiman · 2021-07-27T12:44:04Z

This touches some core logic in the miner, I think we should have a review call to discuss this one.

gballet

I agree with Martin, it seems correct (and I like that you broke some functions down into some with an explicit title) even though we should discuss this during a call. I have a couple nitpicks until then.

rjl493456442 · 2021-07-29T03:04:53Z

Yes @holiman and @gballet . I won't want to merge this PR now, definitely after the fork. And we can schedule a review call for it, especially for some tiny details in the miner refactoring.

Hey @badbitses . This PR is mostly complete. If you are interested in contributing, I would advise to take a look through the open issues and see what piques your interest.

holiman · 2021-11-29T10:13:30Z

It seems that this method is only used for PoS blocks? Which makes sense, because it has noUncle and noExtra set to true, so it's not really abstract.
I find it a bit confusing to have this seemingly abstract block sealer mode for catalyst, whereas the ethash and clique engines use some other path to produce a block. Is the intent to later on align these three engines?

The main reason for catalyst has different path to produce block is it's rpc-event-based engine. While for ethash and clique they are chain-event-based engine, which just create blocks non-stop.

It's still ugly for them to have different paths, but we can find some proper solution to merge these paths I guess.

holiman

Looks ok, but I'm a bit confused by all the changes to the catalyst part.
Also, what I"m a bit scared about is coinbase - it would be bad if these changes make setting the coinbase not "stick".
So if a miner is mining, they need to be able to set the coinbase via,

startup param,
rpc,
- before starting mining,
- and during mining
- and when mining is requested, but during sync, so mining is disabled

Do we have tests for these? Have you experimented anything with these scenarios?

karalabe · 2022-01-05T08:44:37Z

Is this really so in practice? We're going to hold onto the latest 128 states either way for snap sync and reorgs. This clause would only trigger if someone requests mining on something super old. Is that a viable requirement?

Not sure, but I guess so. Consensus layer might reorg to some old branch and require us to build a block there. If the chain is not finalized for very long time, so the deep reorg is expected?

I think so too, since there is not really a guarantee that we won't reorg very deeply with non-finalization

Sure, but we'd get a sethead first from the beacon chain before mining on top, wouldn't we? Which would do the reorg and reconstruction of the needed state? Maybe I'm wrong tho'

MariusVanDerWijden

Some small nits, looks pretty solid to me

MariusVanDerWijden · 2022-01-17T12:21:45Z

I've asked Pari to run this code on a validator on kintsugi. Would be great to also put it on a clique miner maybe? cc @holiman

holiman · 2022-01-17T12:28:58Z

Sure
