I think you should just be able to copy the section from the RCT function to fix this instead of needing to has every tx:
let height = u32_to_usize(output.height);
let miner_tx_id = table_block_infos.get(&height)?.mining_tx_index;
let txid = if miner_tx_id == output.tx_idx {
let tx_blob = table_tx_blobs.get(&miner_tx_id)?;
Transaction::read(&mut tx_blob.0.as_slice())?.hash()
} else {
let idx = u64_to_usize(output.tx_idx - miner_tx_id - 1);
table_block_txs_hashes.get(&height)?[idx]
};
Some(txid)

Ahh I see how we calculate the index now, my bad

@Boog900 #355 (comment) I think RctOutput::tx_idx is good to use here?

Why did this function have to change - I don't like needing to hash the tx for every output where the tx_id is got

Ah my bad, not entirely intended.
Btw random access perf seemed on-par with monerod, it's 1.2x~1.5 faster without tx hash each time.

What
/get_outswas returning the wrong hash, it is fixed by this, including when it needs to return a miner tx hash.
