memray without python?

[lrbison]

Memray has a lot of great interfaces and features! It got me thinking, would it be possible to use the native mode to track allocations in a c application that isn't python at all? I tried something similar using follow-fork and subprocess.run, but I found the binary I executed had no information tracked in memray. It seems like you have all the tools, perhaps all that is missing is an LD_PRELOAD with some stub malloc/free to stand in for PyMalloc. Is this something you've tried or configured?

HI @lrbison and thanks for your message!

Certainly memray can work with all the Python pieces stripped, but that's quite a lot of work to do. Understand that memray it's a very specialised profiler that is quite coupled to ensure it provides the best experience for Python applications in a way that doesn't require to use LD_PRELOAD (so you can activate and deactivate, attach...etc). This means that while it's certainly possible (all the tools are there) it's quite a lot of work to strip that out into it's own thing, so it's unlikely that we will do it.

I see. thank you! I guess I'll stick to python only code for now.
