Subject: [Engine-devel] RFE: Actions on tasks (jobs)
Hi,
We plan to introduce support for gluster tasks in oVirt, using the
current Jobs/steps framework. Which means, any gluster async task
started on a cluster will be shown as a Job in the "Tasks" tab. While
this helps in listing and monitoring the status of all gluster tasks,
we
have a requirement to support a set of actions on such tasks. One
should
be able to select a task, and then, if supported for that task,
perform
one or more of the following actions on it:
- pause
- resume
- abort
- commit
I think this can probably be achieved by introducing a generic
mechanism
for performing actions on task, allowing each type of task to define
what actions are allowed on it in it's current state.
Requesting opinions/suggestions on possible ways to achieve this
requirement.
Several points -
1. By performing actions - you probably mean the entry point to engine will be BllCommand?
StopTaskCommand for example?
If so, we need to think about the permission of the command. who can stop a for example?
What is its role?
2. You mentioned task type - does this mean extending the AsyncTaskType enum? Are you
going to have your own Tasks enum?
Thanks,
Shireesh
