* ReapMaxTxs: return all txs if max is negative this mirrors ReapMaxBytes behavior See https://github.com/tendermint/tendermint/pull/2184#discussion_r214439950 * increase MaxAminoOverheadForBlock tested with: ``` func TestMaxAminoOverheadForBlock(t *testing.T) { maxChainID := "" for i := 0; i < MaxChainIDLen; i++ { maxChainID += "𠜎" } h := Header{ ChainID: maxChainID, Height: 10, Time: time.Now().UTC(), NumTxs: 100, TotalTxs: 200, LastBlockID: makeBlockID(make([]byte, 20), 300, make([]byte, 20)), LastCommitHash: tmhash.Sum([]byte("last_commit_hash")), DataHash: tmhash.Sum([]byte("data_hash")), ValidatorsHash: tmhash.Sum([]byte("validators_hash")), NextValidatorsHash: tmhash.Sum([]byte("next_validators_hash")), ConsensusHash: tmhash.Sum([]byte("consensus_hash")), AppHash: tmhash.Sum([]byte("app_hash")), LastResultsHash: tmhash.Sum([]byte("last_results_hash")), EvidenceHash: tmhash.Sum([]byte("evidence_hash")), ProposerAddress: tmhash.Sum([]byte("proposer_address")), } b := Block{ Header: h, Data: Data{Txs: makeTxs(10000, 100)}, Evidence: EvidenceData{}, LastCommit: &Commit{}, } bz, err := cdc.MarshalBinary(b) require.NoError(t, err) assert.Equal(t, MaxHeaderBytes+MaxAminoOverheadForBlock-2, len(bz)-1000000-20000-1) } ``` * fix MaxYYY constants calculation by using math.MaxInt64 See https://github.com/tendermint/tendermint/pull/2184#discussion_r214444244 * pass mempool filter as an option See https://github.com/tendermint/tendermint/pull/2184#discussion_r214445869 * fixes after Dev's comments
