Python Openstack SDK Show File Upload Via Progress Bar

With the python openstack SDK, you can download an image, chunk by chunk, which allowed me to show a progress bar. You can't seem to do the same when uploading a file. What I want

Solution 1:

So, after quite a bit of searching I was able to find a way to do what I was asking (here & here).

code:

#!/usr/bin/env python3
from types import MethodType

def hook(hookfunk, oldfunc):
    def merged(self, *args, **kwargs):
        hookfunk(self, *args, **kwargs)
        return oldfunc(*args, **kwargs)
    return  MethodType(merged, oldfunc.__self__)


f = open('cirros.qcow2', 'rb')

def new_read(self, size):
    print(self)
    # Or do other code, like updating a progress bar

f.read = hook(new_read, f.read)

f.read()
