Aside:

> OpenResty XRay

At first I thought -- oh, cool, a suite of tools leveraging LLVM's XRay! But then after digging for a bit, I can't tell exactly what this does or how it does it, but it is not quite clear whether it leverages LLVM's XRay. Oh well, it's interesting enough. Buuuut -- they trademarked 'OpenResty XRay'? Seems like it's on the hairy edge of 'confusingly similar' -- it's definitely intended for tracing/introspection.

OpenResty filed for their trademark in 2020 and LLVM XRay goes back at least to ~2016/2017. OpenResty itself has been around since ~2011? But I couldn't find anything in google regarding OpenResty XRay before 2016.

Anyways, interesting spelunking. To be clear, I'm not suggesting that there's anything wrong. LLVM's license permits this kind of commercialization -- if it were the case here.

Searching on X-?Ray debugging, I see a lot of products from separate vendors so I think it's valid to consider XRay alone a general industry term that is based on an obvious analogy, so disputes hopefully have to relate to an entire trademarked name.
