review from https://github.com/paradigmxyz/reth/pull/8264/files#r1646535481 @rkrasiuk
previous behavior: if the entry is occuppied, overwrite the original account state even if old_info is None
current behavior: only overwrite the original account state if old_info is Some.
if old_info is None, original info must still be overwritten
the methods BundleBuilder::state_original_account_info and BundleBuilder::state_present_account_info don't take an Option<AccountInfo as param. so I'm wondering:
- if entry is occupied but the original info is
None, should we pass thenew_infotoBundleBuilder::state_original_account_info? - there is another method
BundleBuilder::set_revert_account_info, that takesOption<Option<AccountInfo>>, is that the one we should be calling here?

@DaniPopes, you're probably familiar with the revm api and can answer this too?

I'm not familiar with state/transitions/bundles APIs

as i mentioned in reviews for #8264, bundle builder API must be improved first before integration in reth |
Merges changes from #8264 and #8861
