First step to fixing cometbft#2925 PR'ing this to see if we have any test failures. Note that this is safe in the happy path, as Reap and CheckTx both share this same lock. The functionality behavior is that: - Full nodes and non-proposers `timeout_prevote` beginning should not block on updating the mempool - Block proposers get _very slight_ increased concurrency before reaping their next block. (Should be significantly fixed in subsequent PR's in - Reap takes a lock on the mempool mutex, so there is no concurrency safety issues right now. - Mempool errors will not halt consensus, instead they just log an error and call mempool flush. I actually think this may be better behavior? If we want to preserve the old behavior, we can thread a generic "consensus halt error" channel perhaps? I'm not sure how/where to best document this. Please also let me know if tests need creating. Seems like the create empty block tests sometimes hit failures, I'll investigate tmrw Also please feel free to take over this PR, just thought I"d make it to help us with performance improvements. Happy to get this into an experimental release to test on mainnets. --- - [ ] Tests written/updated - [x] Changelog entry added in `.changelog` (we use [unclog](https://github.com/informalsystems/unclog) to manage our changelog) - [ ] Updated relevant documentation (`docs/` or `spec/`) and code comments - [x] Title follows the [Conventional Commits](https://www.conventionalcommits.org/en/v1.0.0/) spec --------- Co-authored-by: Sergio Mena <[email protected]>

There was a problem hiding this comment.
@ValarDragon function signature changes here from
abciResponse *abci.FinalizeBlockResponse
to
deliverTxResponses []*abci.ResponseDeliverTx
because of the backport to v0.37.x, I'm not sure how big an issue this is please ack here 🙇
