We won't automatically add stat.S_IWUSER permission to azcopy installation directory any more. Customers have to make sure they have write permission by themselves

PermissionError is thrown by

with open(install_location, 'wb') as f:
f.write(zip_file.read(fileName))

Guess it's better to capture it here?

BTW, there seems to be a bug in azure.cli.command_modules.storage.azcopy.util._urlretrieve, but it will never be hit:

req.read() is already called at

compressedFile = io.BytesIO(req.read())

It is then called again for Python 2:

zip_file = zipfile.ZipFile(StringIO.StringIO(req.read()))

The second req.read() will actually return an empty bytearray:

from urllib.request import urlopen

req = urlopen('https://httpbin.org/get')
print(req.read())
print(req.read())

Output:

D:\cli\py310\Scripts\python.exe D:\cli\testproj\main.py 
b'{\n  "args": {}, \n  "headers": {\n    "Accept-Encoding": "identity", \n    "Host": "httpbin.org", \n    "User-Agent": "Python-urllib/3.10", \n    "X-Amzn-Trace-Id": "Root=1-643e3ce9-695f1a230edbdfe02d8572d5"\n  }, \n  "origin": "167.220.255.31", \n  "url": "https://httpbin.org/get"\n}\n'
