I think this cannot happen in the wild while syncing block, otherwise it would mean the transaction would have no receipt which is impossible.
However in testing conditions or when doing "speculative exeuction", it's possible to get that condition.
This is just to better deal with a potential `nil pointer exception`.
The EVM does memory expansion **after** notifying us about OnOpcode which we use to compute Keccak256 pre-images now. This creates problem when we want to retrieve the preimage data because the memory is not expanded yet but in the EVM is going to work because the memory is going to be expanded before the operation is actually executed so the memory will be of the correct size.
In this situation, we must pad with zeroes when the memory is not big enough.
This change adds a testcase and fixes a corner-case in the skeleton sync.
With this change, when doing the skeleton cleanup, we check if the filled header is acually within the range of what we were meant to backfill. If not, it means the backfill was a noop (possibly because we started and stopped it so quickly that it didn't have time to do any meaningful work). In that case, just don't clean up anything.

The beacon root when applied in `state_processor.go` is performed right before executing transaction. That means that contract reliying on this value would query the same value found in the block header.
In that spirit, it means that any tracing/operation relying on state data which touches transaction must have updated the beacon root before any transaction processing.
This change fixes three flaky tests `TestEth2AssembleBlock`,`TestEth2NewBlock`, `TestEth2PrepareAndGetPayload` and `TestDisable`.

This change removes support for subscribing to pending logs.
"Pending logs" were always an odd feature, because it can never be fully reliable. When support for it was added many years ago, the intention was for this to be used by wallet apps to show the 'potential future token balance' of accounts, i.e. as a way of notifying the user of incoming transfers before they were mined. In order to generate the pending logs, the node must pick a subset of all public mempool transactions, execute them in the EVM, and then dispatch the resulting logs to API consumers.
This pull request defines a gentrie for snap sync purpose.
The stackTrie is used to generate the merkle tree nodes upon receiving a state batch. Several additional options have been added into stackTrie to handle incomplete states (either missing states before or after).
In this pull request, these options have been relocated from stackTrie to genTrie, which serves as a wrapper for stackTrie specifically for snap sync purposes.
Further, the logic for managing incomplete state has been enhanced in this change. Originally, there are two cases handled:
- boundary node filtering
- internal (covered by extension node) node clearing
This changes adds one more:
- Clearing leftover nodes on the boundaries.
This feature is necessary if there are leftover trie nodes in database, otherwise node inconsistency may break the state healing.
time.After is equivalent to NewTimer(d).C, and does not call Stop if the timer is no longer needed. This can cause memory leaks. This change changes many such occations to use NewTimer instead, and calling Stop once the timer is no longer needed.
* use generic atomic types in tx caches
* use generic atomic types in block caches
* eth/catalyst: avoid copying tx in test

Adds a flag `--trace.callframes` to t8n which will log info when entering or exiting a call frame in addition to the execution steps.
