errors when uploading and applying binary configuration files to main and child devices #2318

Closed reubenmiller closed 11 months ago

Describe the bug

thin-edge.io has the following bugs when dealing with the configuration management on the main and child devices:

To Reproduce

Main Device (Uploading from a device to cloud)

  1. Install thin-edge.io and configure to connect to Cumulocity IoT

  2. Configure the configuration plugin to access a binary file using the configuration file

    file: /etc/tedge/c8y/c8y-configuration-plugin.toml

    # Add the configurations to be managed by c8y-configuration-plugin
files = [
    { path = '/etc/tedge/tedge.toml.tar.gz' },
]

  3. Create the dummy binary file on the thin-edge.io device (so there is something to upload)

    cd /etc/tedge
tar czvf tedge.toml.tar.gz tedge.toml.tar.gz

  4. In the Cumulocity UI (Device management application), request the binary configuration file with type /etc/tedge/tedge.toml.tar.gz

Child Device

For downloads, the file is downloaded to the file server, however accessed by a child device, the local http server returns a status code 500 (indicating an unexpected error). Below shows the response shown by the server when access via curl:

curl -f http://172.21.0.2:8000/tedge/file-transfer/TST_bolt_snow_developer/config_update/config1
curl: (22) The requested URL returned error: 500 Internal Server Error

See the linked PR's system tests for the example procedure.

Expected behavior

Configuration files should be treated as plain bytes and the contents should not be assumed to be of any specific format (e.g. utf-8 encoded text). This is applicable for both the main and child devices.

Screenshots

Downloading

Downloading a binary from Cumulocity to the device fails with the failure reason:

Uploading

Uploading a binary from the device to Cumulocity fails with the failure reason:

The issue has been resolved and the test cases have been expanded to cover for both the main and child devices and are viewable here:
