Fixed Inappropriate Logical Expression

[nydelzaf]

Details

While triaging your project, our bug fixing tool generated the following message(s)-

In file: bot.py, method: handle_reaction_events, a logical expression uses the identity operator. A new object is created inside the identity check operation and then used for matching identity. Since this is a distinct, new object, it will not match with anything else. As a result, the identity check will have a logical short circuit and the program may have unintended behavior. iCR suggested that the logical operation should be reviewed for correctness.

Example

Running the following code gives the output-

a = [ None ]
print(a is [ None ])
print(a == [ None ])

False
True

Since the operation here is comparing itself to a list, the == operator should be used for checking equality and != for inequality.

CLA Requirements

This section is only relevant if your project requires contributors to sign a Contributor License Agreement (CLA) for external contributions.

All contributed commits are already automatically signed off.

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.
