The tl;dr is I have a task key and need to get the TaskInfo for it. It looks like the get_view approach is the correct way but it's not working so if I could either A) get it working or B) Figure out why it's not returning the task I would be stoked
FYI - It does work for me. I don't have a chatty system right now, but I just did a self-vMotion which looks like the type of task you had originally. Then looked at the latestTask property and used "task-102" and it worked for me.
http://www.youtube.com/watch?v=krD4hdGvGHM I initiated two new tasks (powerOff and powerOn) and after they finished I hit /task/task-(task-id) (Endpoint that runs the get_view code) and both worked. However the older tasks in the list of tasks for that machine (Tasks returned from TaskCollector) did not work. I wonder if there's some TTL on get_view or something odd. Either way, at least now I can handle the Fault and and know the code is right.
Workflow:
Initiate task on Machine A
/task/task-(new task id)
Hooray, get stuff
Initiate new task on Machine A
/task/task-(new task id)
Hooray, get stuff
/task/task-(old task id)
Boooo, task is gone, despite still showing up in the list of tasks for that machine with full details and with the same task id as it originally had. Nothing changed about the task as far as I can tell except that get_view won't return it
However,
Initiate task on Machine A
/task/task-id get stuff
Initiate Task on Machine B
/task/task-id get stuff
/task/task-old-task-id get stuff
tl;dr I think get_view can only return the most recent task (FOR A SINGLE MACHINE). That seems.... very, very wrong and/or broken.
EDIT: Gah! This doesn't seem to be the case either.
EDIT2: Seems to be time related, it stopped being returned from get_view around 5-7 minutes
So any ideas why get_view doesn't return it but TaskHistoryCollector does?
