Description

core: enable Shanghai EIPs

Rationale

more compatible with ethereum/evm, 6 points need to check

  1. BEP-216: Implement EIP 3855 PUSH0 instruction
  2. BEP-217: Implement EIP3860 Limit and meter initcode
  3. BEP-311: Implement EIP-3651 Warm COINBASE
  4. BEP-312: Announce EIP-6049 Deprecate SELFDESTRUCT
  5. disable EIP-4895 after code upstream
  6. use time based hardfork

Example

  1. to disable EIP-4895, need confirm 3 points:
    a. Parlia.FinalizeAndAssemble ignore Withdrawals
    b. Parlia.verifyHeader ensure header.WithdrawalsHash == nil
    c. ValidateBody ensure block.Withdrawals()==nil
  2. test BEP-216, BEP-217 and BEP-310
    reuse handreds of test cases in https://github.com/ethereum/tests
cd bsc
git submodule update --init --depth 1 --recursive
cd tests
go test -run TestBlockchain -v
go test -run TestState -v
  1. because consensus/parlia: hardfork block can be epoch block, so Shanghai can use time based hardfork

PS: BEP-312 just used as a way to announce, no code need to change

useful to reuse test caes in ./tests

because we change logic in func CalcBaseFee
so we revert this test case, and keep it align with go-ethereum

make runonlylistpat is a list of patterns, so we can add more than one pattern

keep align with go-ethereum,
otherwise some cases will fail

Are we enabling the running of the testcases under ./tests somewhere?

when bsc fork from go-ethereum, many cases in ./tests failed, so they are exclude from unit test at the birth of bsc.
there are hundreds of thousands in ./tests.
in this PR , I will include cases in ./tests, but with limited cases

Which parts specifically refer to enabling Shanghai EIPs apart from the instructionSet code change? I see changes in tests and String() but couldn't quite understand the portions which actually turn Shanghai ON.

define ShanghaiTime in ChapelChainConfig and BSCChainConfig,
but the real time is not determined, it will be filled upon the release for the kepler hardfork
