lizard VS ZLib

No one static analyzer catches everything. It's best to run multiple. Popular ones are cppcheck, clang-analyzer, GCC static analyzer in GCC 10+, flawfinder, lizard.

I searched for "complexity" in VS Code extensions and found Codalyze (and others, but they're not for python.) It's built on Lizard. Does anyone have any experience with this?

A fix has been checked into the upstream git repo: https://github.com/madler/zlib/pull/843 but a release has not yet been made including it.

So the real issue here is that the lack of tree validation before the tree construction, I believe. I'm surprised that this check was not yet implemented (I actually checked libwebp to make sure that I was missing one). Given this blind spot, an automated test based on the domain knowledge is likely useless to catch this bug.

In the source code of the Node.js opensource project, lib folder contains JavaScript code, mostly wrappers over C++ and function definitions. On the contrary, src folder contains C++ implementations of the functions, which pulls dependencies from the V8 project, the libuv project, the zlib project, the llhttp project, and many more - which are all placed at the deps folder.

Seeing the text in red got me thinking for a moment, "wow, didn't realize pirates had such love for an open-source compression library"
