Agenda

• Client updates
• Compiler updates
• Spec updates
  • Creation transaction instead of the irregular state change ipsilon/eof#78
  • define initcontainer_size for EIP-7620
• Testing updates
• Other items
  • discuss EOF version without irregular state change (Creation transaction instead of the irregular state change ipsilon/eof#78) and
  • EOF version without TXCREATE (Remove TXCREATE and InitcodeTransaction ipsilon/eof#76
    this one needs a slight update, tbd soon), after everyone gets on the same page with the proposals
  • discuss initcode mode validation (feat: define initcode mode and require validation of RETURNCONTRACT ipsilon/eof#86)
  • discuss RETURNDATA* 0-padding (feat: change oob behavior of RETURNDATALOAD and RETURNDATACOPY ipsilon/eof#90)
  • Tune EXTCALL with value cost: Tune the cost of EXTCALL with value ipsilon/eof#94.
  • Increase the call's MIN_RETAINED_GAS: Increase the call's MIN_RETAINED_GAS ipsilon/eof#95.

Please add other agenda items or links to discuss.

EOF Call # 43 summary

Clients

• Besu, EVMONE keeping up with current spec
• Geth's implementation progressing at a good pace, working on bugs relating to subcontainer data length

Compilers

• Solidity has an old shanghi era compiler that is a base for mega work
• Compiler teams want some parts of the spec guaranteed before serious work can progress. Specifically the container format and the subroutine and jump functions locked in.

Testing

• Test team is bringing over container testing from retesteth
  • Format is old shanghai fuzzing format, evmone-parse and geth eofdump implement it
• There is a desire to standardize errors for tests, either as strings or as integer numbers
• Client teams expressed willingness to contribute more tests to supplement testing team's work

Specs

• The EOF mega spec is considered to be canonical, EIPs will be brought in line to match
• The following PRs were adopted
  • PR 78 and PR 76 relating to TXCREATE and create transactions
  • PR 86 adding validation rules for init mode and run mode validation
• There was no consensus on the following
  • PR 90 relating to changing zero padding behavior or RETURNDATACOPY in EOF
    • One sentiment expressed by Ipsolon is to not change opcodes, but introduce new ones. This impacts EIP-7676
• New PRs that may be adopted next week
  • PR 94 to change EXTCALL costs to match CALL
  • PR 95 to adjust the min retained gas on a CALL operation

Due to May Day in Europe next week's meeting may be moved, with notice coming no later than Monday the 29th.
