We have hosted the application piranha in order to run this application in our online workstations with Wine or directly.

Quick description about piranha:

Feature flags are commonly used to enable gradual rollout or experiment with new features. In a few cases, even after the purpose of the flag is accomplished, the code pertaining to the feature flag is not removed. We refer to such flags as stale flags. The presence of code pertaining to stale flags can have the following drawbacks. Unnecessary code clutter increases the overall complexity w.r.t maintenance resulting in reduced developer productivity The flags can interfere with other experimental flags (e.g., due to nesting under a flag that is always false) Presence of unused code in the source as well as the binary. Stale flags can also cause bugs. Piranha is a tool to automatically refactor code related to stale flags. At a higher level, the input to the tool is the name of the flag and the expected behavior, after specifying a list of APIs related to flags in a properties file.
