* ----start---- * [PARTIAL cherry-pick] ABCI Vote Extension 2 (#6885) * Cherry-picked #6567: state/types: refactor makeBlock, makeBlocks and makeTxs (#6567) * [Cherrypicked] types: remove panic from block methods (#7501) * [cherrypicked] abci++: synchronize PrepareProposal with the newest version of the spec (#8094) This change implements the logic for the PrepareProposal ABCI++ method call. The main logic for creating and issuing the PrepareProposal request lives in execution.go and is tested in a set of new tests in execution_test.go. This change also updates the mempool mock to use a mockery generated version and removes much of the plumbing for the no longer used ABCIResponses. * make proto-gen * Backported EvidenceList's method ToABCI from #7961 * make build * Fix mockery for Mempool * mockery * Backported abci Application mocks from #7961 * mockery2 * Fixed new PrepareProposal test cases in state/execution_test.go * Fixed returned errors in consensus/state.go * lint * Addressed @cmwaters' comment Co-authored-by: mconcat <monoidconcat@gmail.com> Co-authored-by: JayT106 <JayT106@users.noreply.github.com> Co-authored-by: Sam Kleinman <garen@tychoish.com> Co-authored-by: William Banfield <4561443+williambanfield@users.noreply.github.com>
