Fix an inappropriate test expression to remove a logical short circuit #1559

@munahaf munahaf commented Oct 6, 2023

In file: processor.py, the comparison of Collection length creates a logical short circuit. The length of a collection is always greater than or equal to zero. So testing that a length is less than zero is always false.

I suggested that the Collection length comparison should be done without creating a logical short circuit.

Sponsorship and Support:

This work is done by the security researchers from OpenRefactory and is supported by the Open Source Security Foundation (OpenSSF): Project Alpha-Omega. Alpha-Omega is a project partnering with open source software project maintainers to systematically find new, as-yet-undiscovered vulnerabilities in open source code - and get them fixed – to improve global software supply chain security.

The bug is found by running the Intelligent Code Repair (iCR) tool by OpenRefactory and then manually triaging the results.

Thanks for the fix. Can you do the following before we merge this?

  • You need to add your name to the copying.md file
  • Can you change the check to len(upgrade_effects) == 0? While this is considered unpythonic by some, it makes the check more readable.
