Summary
Backport of #21443 to v4.
This PR fixes a bug in block building where the sequencer would update state even when it failed to execute sufficient transactions. The fix:
NoValidTxsErrorwithInsufficientValidTxsError(includesprocessedCountandminRequired)CheckpointBuilder.buildBlock()so state is not updated for blocks that will be discardedForkCheckpointwrapper to revert world state changes on failureminValidTxsfromCheckpointProposalJobinto the builderCherry-pick conflicts
The second commit (
3ccb6868a8 — Use an additional world state fork checkpoint) conflicted incheckpoint_builder.tsbecause the first commit had already restructured the code into the try/catch/ForkCheckpoint pattern. The conflict was just duplicate leftover code that needed to be removed.Build fix
On v4,
LightweightCheckpointBuilder.addBlock()returnsPromise<L2Block>directly, while onnextit returnsPromise<{ block: L2Block, timings: ... }>. Adjusted the destructuring accordingly.Commit structure
