Task progress lost and timeout during migration

[DavidePrincipi]

The NS7 migration tool starts the import-module task, which can last multiple days. After 8 hours, the task progress is no longer displayed on the NS8 side. If the Finish phase takes more than 10 minutes, an NS7 exception occurs on the NS7 side.

Steps to reproduce

• Start Nextcloud migration
• Sync
• Wait 8 hours (1)
• Finish migration

Expected behavior

After 8 hours the Task progress is still visible in cluster-admin. The Finish phase can last more than 10 minutes without timeout error.

Actual behavior

The Task progress is lost in cluster-admin. Furthermore, if the Finish phase takes more than 10 minutes the following exception occurs:

Traceback (most recent call last):
  File "/usr/sbin/ns8-action", line 126, in <module>
    ret = wait_task(api_endpoint, payload['token'], task_id)
  File "/usr/sbin/ns8-action", line 62, in wait_task
    raise Exception("No server response")
Exception: No server response

Components

• ns8-core 3.4.4
• ns8-nextcloud 1.1.9

• nethserver-ns8-migration-1.2.1-1.1.gdffa2ac.ns7.x86_64.rpm x86_64

In testing

• core 3.7.0-dev.1
• nethserver-ns8-migration-1.2.1-1.1.gdffa2ac.ns7.x86_64.rpm

Test case

Check the bug is not reproducible.

1. With the migration tool in testing, the timeout of 10 minutes occurring in the Finish phase does not happen any more. It is possible to add a sleep 700 in NC configure-module action at index 90, to simulate a slow Finish phase.
2. With Core 3.7+ we expect the task is shown as running in cluster-admin UI as long as the NC migration isn't finished.
