Stuff to discuss

• Testing Update
• Osaka Migration
• EXTCALL return values
• HASCONTRACT

[shemnon]

• Current release tests (EOF on top of prague) are broken

  • Besu had a 7702 bug, all non-7702 tests are fine.
  • Next release will be released after devnet 4 is released
  • PR reviews are mostly caught up
  • Testing focus is on devnet 4 for the next week

• Compiler

  • Vyper create from blueprint needs a re-work for EOF.
  • Create form EXT Contract would have helped.
  • Cannot blueprint off of any contract in EOF like you could in legacy
  • A factory deployer would be good, delegate call into a contract that EOF creates. As opposed to an initcode only contract

• Osaka Migration

  • Clients need to target Osaka for EOF activation
  • Tests need to target Osaka, including moving tests in source tree
  • We have 6 more months to reifine the spec
  • We can look into HASCODE
  • We can reconsider EXT*CALL return code numbers
  • cleanup: EOFCREATE stack order
  • cleanup: Remove hashing of container in EOFCREATE
  • cleanup: Rename RETURNCONTRACT to RETURNCODE

• Open questions

  • Implications of gas introspection: regarding a gas to eth EIP.

  Next Meeting:

  • Rename RETURNCONTRACT -> RETURNCODE
  • HASCODE / ERC-721 solution
  • EXT*CALL return code, keep or revise?
  • EOFCRAE stack order
  • remove container hashing in EOFCREATE
