Summary
A 20-year-old bug in the Enlightenment E16 window manager was fixed by Kamila Szewczyk, a 21-year-old developer. The bug caused the desktop to freeze when opening certain PDFs due to an infinite loop in the window-title truncation algorithm. Szewczyk discovered the issue while preparing lecture slides at Saarland University. The bug was traced to the lack of an iteration limit in the truncation algorithm, which could lead to a denial-of-service scenario. The fix, released as a patch against E16 1.0.30, includes capping iterations at 32 and preventing negative corrections. Szewczyk criticized modern software development practices, arguing they lead to instability. The E16 window manager, first released in 1997, is still maintained by a small community of enthusiasts despite the existence of newer versions. This incident highlights the potential for similar bugs in modern software systems. Key Points: • A 20-year-old bug in E16 caused desktop freezes when opening specific PDFs. • The bug was fixed by a developer who prefers the older window manager over modern alternatives. • The fix includes capping iterations to prevent infinite loops in the truncation algorithm.
