EF2: "Permission denied:" when deploying python extension on Windows ActiveGate

AntonioSousa — Tue, 29 Oct 2024 21:43:05 GMT

I have developed an EF2 extension that has to be deployed on a Windows server. It is giving a "Permission denied:" error in the logs, when it is being deployed:

It's not a certificate issue, as another modified WMI extension is working OK in the server. It is the first python extension though.

Another interesting thing is that the __init__.py referenced is a 0 byte python file. It doesn't seem to have any permission issues though. The environment is a restricted environment, with no Internet connectivity.

Has anyone got any issue similar to this, developing custom extensions in Windows AGs?

- I've faced the same issue when activating venv while testing locally, and it worked well when I deactivated venv.

- other thing, this may because of you've dependencies is already installed in your development environment but not included in setup.py under `install_requires` or `extra_requires` as the following figure

- regarding __init__.py it makes python treats the current directory as package and it was important for defining the namespace of the .py files included in the same directory (before version 3.3) as the namespace of each class take the same name of the current directory of the __init__.py, Since python version 3.3 it's automatically build namespaces and this file became optional.

@MostafaHussein,

It doesn't seem to be related to my extension. It's complaining about the __init__.py file that comes inside pip, inside the python distributed with AG:

C:\Program Files\dynatrace\remotepluginmodule\agent\res\dsruntime\python3.10\lib\site-packages\pip\_internal\utils\__init__.py

In the meantime, I tried the trick of putting in a "#" in the file, so it isn't 0 bytes, but that didn't help either.
