This will cause an error if there has been a reorg since we fetched the batches. In normal mode, this should never happen, since we check for reorgs and then fetch batches synchronously. But in preconfirmations mode, the batches are fetched asynchronously wrt to the reorg detection, and so the L2 head can change under us. In this case the new check will fail and we will re-fetch preconfirmations after checking the new L2 head. Fixes EspressoSystems/espresso-polygon-zkevm-demo#246

Finally have a test for this, and it doesn't work, because, as I learned recently, SQL transactions aren't exclusive. So it is possible for the DB to get reset in between doing this check and processing the batch. Anyways, I decided it was better to explicitly synchronize with the preconf task whenever we are about to reset the DB, rather than try to detect it after it happens. That fix is in #87 |
