0.6.0 - 2019-02-15

This release adds 3 new detectors, 5 new printers, improves the overall usability of Slither, and introduces a new tool: slither-check-upgradability to help to review upradable contracts. User and developer documentation has dramatically improved. This release brings also several bugfixes, API enhancements and lowers the rate of false positives for several detectors.

Thanks to our external contributors @cty12, @mrice32 and @ptare for their numerous bug reports.

Added

• Detectors:
  • erc20-interface: Incorrect ERC20 interfaces
  • erc20-indexed: Un-indexed ERC20 event parameters
  • deprecated-standards: Deprecated Solidity Standards
• Printers:
  • data-dependency: Print the data dependencies of the variables
  • function-id: Print the keccack256 signature of the functions
  • modifiers: Print the modifiers called by each function
  • require: Print the require and assert calls of each function
  • variable-order: Print the storage order of the state variables
• Command line usage:
  • --ignore-truffle-compile: do not run truffle compile
  • --disable-color: disable output colorization
  • --triage-mode: run slither in its triage mode. For every finding, Slither will ask if the result should be shown for the next run.
  • --filter-paths: exclude all the results that are only related to the given paths.
  • Configuration file: Slither options can be configured through a JSON file. See the documentation
• slither-check-upgradability: Utility to help reviewing upgradable contracts
• Dependency: require pysha3>=1.0.2

Changed:

• Reduce the false alarms rates of:
  • Unused variables: consider expression oustide of the functions' scope #167
  • Reentrancy: check if a call to this is reentrancy-safe + don't consider view/pure calls for Solidity >= 0.5 #127 #126
  • Locked ether: follow libraries calls #163
• Improve Truffle integration: Slither will automatically switch to the truffle version provided in package.json (#154)
• Improve SSA conversion: Use of an interprocedural sensitive analysis (follow parameters) (#156 (comment))
• Improve data dependency: Compute a fix-point on function context (#171)
• Improve inheritance printer output (#162, #166)
• Add support of staticall (#152)

Fixed

• Several minors bugs, including:
  • Incorrect SSA conversion on Return (59af388)
  • is_storage property on StateVariableIR/LocalVariableIR (59af388)
  • Crash when two variables have the same name #151
  • Incorrect location for LocalVariableIR (#143)
  • Add constant folding visitor to avoid crash on expression-based length (#144)
