[azure-iot-sdk] [v2.12.0] ensure_desired_properties kwarg at False seems not work

[fhouge]

I try to disable the following feature: Fetching the latest twin when reconnecting.
I use the azure-iot-sdk-python v2.12.0.

In the release, I see:
Fetching the latest twin when reconnecting is now optional (using the ensure_desired_properties kwarg)

So, I try to set to False this parameter with the following call when I create my module client:

self.client = IoTHubModuleClient.create_from_edge_environment(ensure_desired_properties=False)

I build my module with this change and i deploy it on my device.
When I test this change, I see the following message at the module launch:
INFO get_twin(async_clients.py:442): Getting twin
--> as expected

But one hour later and each following hour, I see:
INFO _handle_pipeline_event(pipeline_stages_iothub.py:129): EnsureDesiredPropertiesStage: Reconnected. Getting twin
--> not expected with ensure_desired_properties parameter at False.

I try the following hack after the call to create_from_edge_environment without kwargs parameter:

self.client = IoTHubModuleClient.create_from_edge_environment()
self.client._mqtt_pipeline._pipeline.nucleus.pipeline_configuration.ensure_desired_properties = False

And with this hack, the following message disappear each hour as expected:
INFO _handle_pipeline_event(pipeline_stages_iothub.py:129): EnsureDesiredPropertiesStage: Reconnected. Getting twin

I find in the SDK code the following lines:

        # Pipeline Config setup
        config_kwargs = _get_config_kwargs(**kwargs)
        pipeline_configuration = pipeline.IoTHubPipelineConfig(
            device_id=device_id,
            module_id=module_id,
            hostname=hostname,
            gateway_hostname=gateway_hostname,
            sastoken=sastoken,
            server_verification_cert=server_verification_cert,
            **config_kwargs
        )
        pipeline_configuration.ensure_desired_properties = True

The kwargs parameter that can contain ensure_desired_properties parameter is processed but after that, the ensure_desired_properties parameter is set to True. So, it is not possible to set this parameter to False.

Do you have a solution for this issue?

@fhouge Good catch - not sure how this got overlooked - I'll work on implementing a solution as soon as I can

[cartertinney]

Fixed in #1169 and will be included in the next release. Apologizes for the long delay

azure-iot-device version 2.13.0 is available now. Will close this issue - if anything is not working as expected, please open a new issue.
