- Loop startup waitpid on EINTR; kill and reap the child on fatal error or when interrupted, instead of leaking a ptrace-stopped process. - Treat PTRACE_DETACH failure as fatal -- otherwise the child is stuck stopped forever. - Zero-initialize procName so the memcpy into ___tracy_magic_process_name does not copy uninitialized stack past the NUL. - Forward SIGINT to the child from the signal handler when in forked mode, so Ctrl-C during a blocking waitpid unblocks cleanly. - Preflight perf_event_open on the target before StartupProfiler so permission failures surface with actionable guidance instead of silently producing no samples. - Also handle SIGHUP and SIGQUIT.
Tracy Profiler
A real time, nanosecond resolution, remote telemetry, hybrid frame and sampling profiler for games and other applications.
Tracy supports profiling CPU (Direct support is provided for C, C++, Lua, Python and Fortran integration. At the same time, third-party bindings to many other languages exist on the internet, such as Rust, Zig, C#, OCaml, Odin, etc.), GPU (All major graphic APIs: OpenGL, Vulkan, Direct3D 11/12, Metal, OpenCL, CUDA.), memory allocations, locks, context switches, automatically attribute screenshots to captured frames, and much more.
