How Do I Debug An Extension?

Answer»

When USING GDB with dynamically loaded extensions, you can't SET a breakpoint in your extension until your extension is loaded.
In your .gdbinit file (or interactively), ADD the command:
br _PyImport_LoadDynamicModule
Then, when you run GDB:
$ gdb /local/bin/python
gdb) run myscript.py
gdb) CONTINUE # repeat until your extension is loaded
gdb) finish # so that your extension is loaded
gdb) br myfunction.c:50
gdb) continue
