LLDB python scripts to extend SOS commands for .NET debugging on Linux
In LLDB, execute:
command script import <path to>/LldbSosExts.py
- allclrstacks - Prints CLR stacks for all the threads in the process
- rsc - Runs an SOS command and writes its output to a file (tempsos.txt)
- gfs - Gets the first instance of a type from the top of the thread stack
- dko - Dumps the simplified contents of a known .NET object
- etec - Expands thread execution context of first thread on the stack
- eoh - Executes a command on every object address given a method table address
eoh <mt addr> <cmd>
Get the Method Table (mt) address (e.g. like from dumpheap output). The cmd is a single word command to run on each object address. The eoh command runs a dumpheap -short -mt <mt addr> and then runs cmd on each object address.
If you get something like NameError: name 'run_one_line' is not defined, there is an issue with the Python installation. Exit LLDB and try running these commands:
sudo apt update
sudo apt install python3
sudo apt install python3-lldb
ln -s /usr/lib/llvm-14/lib/python3.10/dist-packages/lldb/* /usr/lib/python3/dist-packages/lldb/
