Code Smell 57 - Versioned Functions

sort, sortOld, sort20210117, workingSort, It is great to have them all. Just in case

Problems

  • Readability

  • Maintainability

Solutions

  1. Keep just one working version of your artifact (class, method, attribute).

  2. Leave time control to your version control system.

Sample Code

Wrong

findMatch()
findMatch_new()
findMatch_newer()
findMatch_newest()
findMatch_version2()
findMatch_old()
findMatch_working()
findMatch_for_real()
findMatch_20200229()
findMatch_thisoneisnewer()
findMatch_themostnewestone()
findMatch_thisisit()
findMatch_thisisit_for_real()

Right

findMatch()

Detection

We can add automatic rules to find versioned methods with patterns.

Like many other patterns we might create an internal policy and communicate.

Tags

  • Versioning

Conclusion

Time and code evolution management is always present in software development. Luckily nowadays we have mature tools to address this problem.

Original idea


That's why I write, because life never works except in retrospect. You can't control life, at least you can control your version.
