From 7c51cecbcaf54e74d86ee5c89aa2b06387fd53ee Mon Sep 17 00:00:00 2001 From: Rich Trott Date: Sat, 6 Feb 2021 08:03:04 -0800 Subject: [PATCH] util: use assert for unreachable code Great effort is taken to keep `util.inspect()` from throwing while inspecting a linked list or other items that require recursion. It is likely still possible at this time to cause a throw with prototype pollution, but that will change soon when the code is modified to use primordials. This commit instructs our coverage to not be concerned about not being able to reach the throwing-an-error code and changes the throw there to an assert so users will be instructed to open a bug with Node.js should they manage to cause the code to throw.
