14:32 <antocuni> this looks like a nice visualizer for flame graphs: https://www.youtube.com/watch?v=cFuI8SAAvJg&ab_channel=NetflixOpenSource

14:33 <antocuni> it would be interesting to use it with vmprof profiles

15:40 <mattip> how far is vmprof output from a perf-compliant format?

15:46 <antocuni> I don't know, but it should not be hard to make it so

15:46 <antocuni> IIRC there was a pypi 3rd party package to do so, at some point

16:53 <mattip> https://github.com/methane/vmprof-flamegraph

16:54 <mattip> it uses flamegraph.pl

16:57 <mattip> https://github.com/brendangregg/FlameGraph

16:59 <mattip> ... and uses stats = vmprof.read_profile(profile) to read a file named "profile"

17:10 <muke> Hey, I'm running some of the llvm code I've written for the first time and finding the lltype system doesn't like void pointers - are they possible at all within rpython?

17:30 <muke> oh, catching in the docs that the problem is pointing to primitives at all instead of void specifically

17:31 <muke> I'm still a little unclear on how I can obtain a void pointer through the rffi though, a struct with a single field of type void isn't what I want, is it?

17:33 <muke> for context I'm trying to interface with the llvm-c api which doesn't actually define it's types as they're really C++ classes that C can't represent, and the only way I've seen python interact with this is treating them as void pointers

18:22 <cfbolz> muke: rffi.VOIDP

18:24 <muke> cfbolz ah, thank you
