  "message": "perfetto: heap_profile: add host subcommand for local Linux profiling (#5049)\n\nAdds \u0027heap_profile host -- mybinary args\u0027 for profiling local Linux\nprocesses without an Android device, using LD_PRELOAD and the\nheapprofd glibc preload library.\n\ntracebox run without a subcommand with --system-sockets handles both\nthe traced daemon and the session in a single invocation. --notify-fd\nblocks until the session is active before launching the profiled\nbinary. PERFETTO_HEAPPROFD_BLOCKING_INIT\u003d1 ensures the binary\u0027s first\nmalloc waits for heapprofd to fully attach.\n\nThe libheapprofd_glibc_preload.so prebuilt is downloaded from GCS\nautomatically (linux-amd64/arm/arm64). A --preload-library flag\nallows overriding the path for local builds.\n\nAlso adds heapprofd_glibc_preload to the roll-prebuilts manifest so\nit is updated alongside the other prebuilts on each release.",
