With this change, we are seeing problems in certain cases when a python
function (def foo():) is being resolved. d.getVar("foo") would return None
and then fail from not having a startswith() method:
ERROR: Build of do_unpack failed
ERROR: Traceback (most recent call last):

if not body.startswith("def"):
AttributeError: 'NoneType' object has no attribute 'startswith'
Our qemu_%.bbappend contains the following:
def _remove_git_submodule_file(filename):
import os
if not os.path.isfile(filename):
return
os.unlink(filename)
do_unpack_append() {
_remove_git_submodule_file(d.getVar("S", True) + "/dtc/.git")
_remove_git_submodule_file(d.getVar("S", True) + "/pixman/.git")
}
Moving the function to within do_unpack_append would solve the problem.
