I've worked with people who believe this, including at least one devout follower of Clean Code and I totally disagree. One developer's obvious self-documenting code is another developer's WTF. Yeah, some projects have a lot of code that doesn't need to be commented, especially web and GUI projects that have a lot of similar code for performing CRUD operations on various database objects. That shouldn't make you get out of the habit of commenting things that actually need to be commented. One major WTF in this code that stood out for me is the place where char zExtra is cast to const char * * . (Pointer-to-pointer casts should be alarming for any C programmer.) Only later, I realised that zExtra was a block of memory containing three arrays of different type. There should at least be a brief comment explaining the memory format of zExtra, and maybe one explaining why the code makes a single allocation instead of three separate allocations (is it performance critical?)
