0.2.2 - 2018-10-30

Thanks to our external contributors!

Added

  • New API for generating a testcase only if a certain condition can be true in the state. Useful for conveniently
    checking an invariant in a state, and (ManticoreEVM.generate_testcase(..., only_if=)) generating a testcase if it
    can be violated.
  • New constrain= optional parameter for State.solve_one and State.solve_buffer. After solving for a symbolic variable,
    mutate the state by applying that solution as a constraint. Useful if concretizing a few symbolic variables, and later
    concretizations should take into account previously solved for values.
  • ManticoreEVM.human_transactions top level API. Mirrors ManticoreEVM.transactions, but does not contain any internal
    transactions.
  • Emit generated transaction data in human readable format (JSON)
  • Warning messages if number of passed arguments to a Solidity function is inconsistent with the number declared
  • CLI support for the ReentrancyAdvancedDetector
  • Colored CLI output
  • Configuration system. Allows configuration options to be specified in a config file. New configurations are available,
    notably including solver parameters such as solver timeout, and memory limits.
  • Support for some unimplemented x86 XMM instructions
  • Customizable symbolic stdin input buffer size
  • Support for Etheno
  • RaceConditionDetector that can be used to detect transaction order dependencies bugs

Changed

  • Improve the DetectExternalCallAndLeak detector and reduce false positives
  • Numerous improvements and changes to the SolidityMetadata API
  • Ethereum contract addresses are no longer random, but are deterministically calculated according to the Yellow Paper
  • Manticore no longer supports contracts with symbolic addresses creating new contracts. This is a consequence of
    supporting determinstic contrat address calculation. There are plans for reenabling this capability in a future release.

Deprecated

  • Several SolidityMetadata APIs: .get_hash(), .functions, .hashes

Fixed

  • Numerous fixes and enhancements to the Ethereum ABI implementation
  • Better handling of overloaded functions in SolidityMetadata, and other bug fixes
  • Fixes for the FilterFunctions plugin
  • Fixes for symbolic SHA3 handling
  • Many EVM correctness/consensus fixes
  • Numerous spelling errors
