Could not find document about heap profiling with new tcmalloc about tcmalloc HOT 4 CLOSED

Na

The API in malloc_extension.h provides access to TCMalloc's heap profiler. This covers

• Snapshots (tcmalloc::MallocExtension::SnapshotCurrent), such as the sampled heap profile of current live objects. We also collect a peak heap profile when the application heap (by user-accessible bytes) hits a high water mark.
• An allocation profile (tcmalloc::MallocExtension::StartAllocationProfiling), to collect a time series of sampled allocations during that session.

We have not yet open-sourced a library for converting from this profile to the protocol buffer format understood by https://github.com/google/pprof.

Any progress on open-sourced library for converting Profile to protocol buffer format understood by https://github.com/google/pprof.
It will be very useful to have a tool to looking at the memory profile.

Hello,

Is there a recommended workaround for this issue? Using TCMalloc without access to a usable view of the memory profile is very limiting for any serious development.

Also, I would love to learn about the timeline for the fix.

As of 5d5968a, there is an interface (in tcmalloc/profile_marshaler.h, tcmalloc::Marshal) for converting from the profile instance collected by TCMalloc to a binary-encoded profile suitable for use with https://github.com/google/pprof.
