In many cases, debugging a program by stopping its execution is not acceptable, delays introduced by a debugger might cause the program to change its behavior drastically, or perhaps fail, even when the code itself is correct. Troubleshooting a live system, chasing a race condition, debugging problems happening only under heavy load or on a multi-core system, or investigating user interface issues, are such examples. To address this, DSF-GDB, the new debugger integration of the CDT, is being extended to support the use of tracepoints which can dynamically be inserted and controlled in a live system.
In this talk we will cover such concepts as dynamic and static tracepoints, fast tracepoints, remote tracing, disconnected tracing, visualization of data and many more.
Beyond the topic of tracepoints, we will also discuss what advanced debugging features (e.g. multi-core awareness) are planned for the next release of the CDT and of GDB.
