Agenda

• Client updates
• Compiler updates
• Spec updates
  • IS_CONTRACT vs multiple return codes for EXT*CALL for detecting EOAs and maybe EOF calls. Which is superior? Which should be specced out fully?
• Testing updates
  • short-term and long-term approach to the testing of EOF gas usage of opcodes
• Other items
  • Devcon Talks... Who is submtting and does anyone want collaborators?
  • A discussion on Fuzzing as part of testing updates

Please add other agenda items or links to discuss.

Next call on Aug 7th, 2024

[shemnon]

A couple of non-boilerplate items

• Devcon Talks... Who is submtting and does anyone want collaborators?
• A discussion on Fuzzing as part of testing updates

Also for spec updates

• IS_CONTRACT vs multiple return codes for EXT*CALL for detecting EOAs and maybe EOF calls. Which is superior? Which should be specced out fully?

[pdobacz]

Testing item:

• short-term and long-term approach to the testing of EOF gas usage of opcodes

[shemnon]

Third option for contract detection: use flags to detect if a contract was called, cleard after next CALL opeation.

[shemnon]

[ ] Post PR to reintroduce EXTCODESIZE in EOF. For now keep HASH and COPY banned.

[frangio]

An argument for enabling EXTCODEHASH too is the ability to work around the EOF→Legacy EXTDELEGATECALL restriction, which otherwise creates a new way to brick a proxy.

[shemnon]

Mario will look into adding fuzzing to EEST and report back with what it would take next call.

[shemnon]

In addition to gas cost testing we need OOG tests, to gauge OOG behavior.

CLosing in favor of #1115
