The scan consumes the final Waiting/SharedHolding flags of each lock map: a thread blocked in a lock acquisition emits no Obtain and no other event, so an unclosed wait at the last known state is a permanent wait per the event contract. A failed try_lock never emits a wait, so it cannot fabricate an edge. Locks recorded by clients with inverted release ordering are skipped entirely, as their holder attribution is ambiguous. A thread that holds a shared lock and waits for exclusive cannot progress while its own shared hold persists; this is reported as a size-1 cycle.
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 graphics/compute APIs: OpenGL, Vulkan, Direct3D 11/12, Metal, OpenCL, CUDA, WebGPU.), memory allocations, locks, context switches, automatically attribute screenshots to captured frames, and much more.
