Adding feature to re-trigger jobs from the GUI

[gbena]

When Servers (providers) are not available, Hakbot jobs will fail. This is normal. Once the servers are up again, it would be very handy if we could re-trigger the failing jobs to run again directly from the UI.

Unavailable jobs should automatically be retried. If the provider continues to be unavailable, the state of the job will remain as unavailable and will continue to retry.

At present, the UI is not feature parity with the REST API. The API has a lot more functionality, although manually retriggering (or resubmitting) is not one of those options.

Options should exist in the UI to:

• Cancel job (based on providers ability to do so)
• Delete job
• Retry / Resubmit job
