Infer + Extension Runtimes on Java Projects

  • Stats for file- and LOC count are taken from the program cloc executed on the project folder.
  • Infer command used: infer --cost-only --keep-going -- <build-command>
    • --keep-going ensures that infer attempts to continue its analysis even when it encounters a failure somewhere.
  • Time for loading data into extension was taken by measuring the execution time of the readInferOut function in inferController.ts
  • Time for receiving the feedback that the cost might have changed after a potentially significant code change was measured on the Java source file in the project with the highest LOC (again, according to cloc). The code change is the addition of while (false) {} in the last method of the file.
  • PC specs:
    • OS: Manjaro Linux
    • Processor: Intel(R) Core(TM) i7-6700HQ CPU @ 2.60GHz, 8 Cores
    • RAM: 8GB
