GDB - The GNU Project Debugger ============================== `The GNU Project Debugger (GDB) <https://www.sourceware.org/gdb>`_ is a powerful tool that allows you to analyze the execution flow of a process. GDB can help to find bugs, uncover crash errors or track the source code during execution of a development cluster. It can also be used to debug Teuthology test runs. GET STARTED WITH GDB -------------------- Basic usage with examples can be found `here. <https://geeksforgeeks.org/gdb-command-in-linux-with-examples>`_ GDB can be attached to a running process. For instance, after deploying a development cluster, the process number (PID) of a ``ceph-osd`` daemon can be found in:: $ cd build $ cat out/osd.0.pid Attaching gdb to the process:: $ gdb ./bin/ceph-osd -p <pid> .. note:: It is recommended to compile without any optimizations (``-O0`` gcc flag) in order to avoid elimination of intermediate values. Stopping for breakpoints while debugging may cause timeouts, so the following configuration options are suggested:: [osd] osd_op_thread_timeout = 1500 osd_op_thread_suicide_timeout = 1500 Debugging Teuthology Tests ^^^^^^^^^^^^^^^^^^^^^^^^^^ ``src/script/ceph-debug-docker.sh`` can be used to analyze Teuthology failures:: $ ./ceph-debug-docker.sh <branch-name> Refer to the script header for more information.
