Add two new commands to GDB that can be placed into the early
initialization to control how Python starts up. The new options are:
set python ignore-environment on|off
set python dont-write-bytecode auto|on|off
show python ignore-environment
show python dont-write-bytecode
These can be used from GDB's startup file to control how the Python
extension language behaves. These options are equivalent to the -E
and -B flags to python respectively, their descriptions from the
Python man page:
-E Ignore environment variables like PYTHONPATH and PYTHONHOME
that modify the behavior of the interpreter.
-B Don't write .pyc files on import.
