Feature fantasy: memory profile in Windows via Sysinternals VMMap

[hunterhogan]

First, I love your extension. Thank you very much for your hard work.

I develop in Windows, and I haven't yet learned how to easily develop in WSL and Windows simultaneously; therefore, I haven't yet used the memray capabilities of Flamegraph.

I have tried to profile memory usage with Sysinternals VMMap, but ... Let's just say the learning curve is much steeper than learning how to easily develop in WSL and Windows simultaneously. 😄

As compared to memray, Sysinternals VMMap would almost certainly be much more difficult to integrate, so this is a feature fantasy, not a feature request.

Thanks for your feedback, and also for your review! I really appreciate it!

I don't have any experience with VMMap -- so I'm not sure how that would work out in practice. I installed it and tried attaching to a Python process, this is what is produced:

vmmap-output.csv

To create a flame graph, I would need memory allocation by function name at one point in time (for the Flamegraph extension the high watermark is chosen by default). Can vmmap provide this?

Can vmmap provide this?

I have no idea. I didn't understand most of what vmmap showed me. :)
