Detects functions with potential side-effects. Same as "purity", but implemented on top of Pulse.

Activate with --impurity.

Supported languages:

  • C/C++/ObjC: Experimental
  • Java: Experimental

This is an experimental inter-procedural analysis that detects impure functions. It is meant to be an improvement over the purity analysis with a negation on the issue types. For each function, impurity analysis keeps track of not only the impurity of the function but also some additional information such as which parameters/globals the function modifies. It models functions with no summary/model as impure. The analysis relies on Pulse summaries to determine impurity.
