Instead of loading all txs from the p2p pool and validating them all, we now get an iterator to the p2p pool and iteratively run through them and validate them as we go. This ensures we only load and validate strictly the txs we need. This also makes it easy to enforce new block constraints such as gas limits, which we add as two new env vars.
As part of this PR, we also change the interface of validators. Since there is no point anymore in validating txs in bulk, we drop the
validateTxs
method in favor of justvalidateTx
. And since we're at it, we enrichvalidateTx
to returnvalid/invalid/skip
and to include the failure reason.Fixes #10869
