Unreleased

No changes yet :)

v6.0.0-beta.3

Potentially breaking changes

  • #547 requires your integration to understand the network ByzantiumToConstantinopleAt5, which is analogous to existing pseudo networks such as FrontierToHomesteadAt5 and EIP158ToByzantiumAt5.

  • #557 changes the format of the rlp tests, byte strings are now prefixed with "0x"

EIP 1234

  • #547 added a test for the difficulty changes. This adds the network ByzantiumToConstantinopleAt5, which is analogous to existing networks such as FrontierToHomesteadAt5 and EIP158ToByzantiumAt5.

EIP 1052

  • #548 Added a test for EXTCODEHASH called on an account created in the same transaction
  • #549 added a few more tests for EXTCODEHASH and EXTCODESIZE on accounts created in the same transaction
  • #550 Checks that changes to an account's nonce, balance, or storage do not change the result of calling EXTCODEHASH
  • #552 Added another EXTCODEHASH test, what if it's run on accounts which have self-destructed?
  • #563 Another spectacularly detailed test case of EXTCODEHASH involving recursive calls and oog-induced revert
  • #566 checks that EXTCODEHASH returns a different result when the code changes
  • #568 adds a test for EXTCODEHASH; what if the contract being hashed self destructed while in the middle of a delegate call?
  • #569 calls EXTCODEHASH on an empty contract

Misc

  • #551 tests for a Constantinople bug the fuzzer found in geth
  • #544 adds an RLP test, courtesy of the mana team
  • #557 changes the format of the rlp tests, byte strings are now prefixed with "0x"
  • #561 changed some of the tests. There were some changes to testeth which made the previous tests impossible to regenerate. They were refactored but not in a way which should break any client.
  • #567 adds a Constantinople test Mana found when they failed to sync with Ropsten

v6.0.0-beta.2 Release CW 46

Constantinople Test Updates

  • Added initial test cases for EXTCODEHASH EIP-1052, see PR #484
  • More EXTCODEHASH tests, see PR #544
  • New SSTORE state tests and blockchain tests where an external call is overwriting/colliding with new SSTORE gas calculation rules, see PR #535

Test Coverage

  • New tests to cover cases where the result of an EVM opcode is written to a specified memory range and the result is shorter than the specified range, see PR #538

Library Changes

  • Added .idea to .gitignore, see PR #546

Docs

Test generation docs have been consolidated and integrated in the central ReadTheDocs testing documentation.

We also updated outdated parts on this doc section (see PR #539), so it should in principle now be possible to follow the guide and end up with a working test creation setup. There might still be some glitches, please let us know or submit a PR on ethereum/tests to if you stumble over something.

v6.0.0-beta.1 Release CW 43

Constantinople Test Summary

  • EIP-145 (Bitwise shifting): Tests for SAR, SHL and SHR in GeneralStateTests/stShift directory, blockchain tests analogue
  • EIP-1014 (CREATE2): Various cases covered in GeneralStateTests/stCreate2 directory, blockchain tests analogue
  • EIP-1052 (EXTCODEHASH): Tests not merged yet, open PR #484
  • EIP-1283 (SSTORE): Dedicated tests in GeneralStateTests/stSStoreTest directory also covering Ropsten consensus issue cases, blockchain tests analogue, generally refilled state tests with new SSTORE gas metering rules in PR #511
  • EIP-1234 (difficulty): New difficultyConstantinople.json file and regenerated difficultyRopsten.json files in the BasicTests directory, see PR #518

Library Changes

Be aware that the format of BlockchainTests recently changed with the introduction of a new field sealEngine (values: NoProof | Ethash), see related JSON Schema change or BlockchainTest format docs for reference.

This means that you can faster-execute NoProof based tests skipping block validation. These tests nevertheless doesn't provide reliable values for PoW-based block header fields any more (mixHash, nonce), so make sure that you don't rely on the correctness of these values for the tests to pass.
