Problem
The code to generate symbolized pprof heap profiles and flamegraph SVGs has been upstreamed to the
jemalloc_pprof
crate:symbolize
feature for online symbolization polarsignals/rust-jemalloc-pprof#22flamegraph
feature polarsignals/rust-jemalloc-pprof#23Summary of changes
Use
jemalloc_pprof
to generate symbolized pprof heap profiles and flamegraph SVGs.This reintroduces a bunch of internal jemalloc stack frames that we'd previously strip, e.g. each stack now always ends with
prof_backtrace_impl
(where jemalloc takes a stack trace for heap profiling), but that seems ok.
