Not possible to select upcoming time slot for "Distribute materials"
Last modified: 2015-05-11 19:24:53 CEST
In the "Distribute materials" module of UCS@school I am able to select a "Distribution time" for the automatic distribution of my files. However, it's not possible to select the next available time slot (15 minute steps).
It's 10:38. I want to automatically distribute files at the next available time slot wich is "10:45". When clicking on "Create project", an error message appears:
"The specified time needs to lie in the future for: Project distribution"
That's reasonable, but in this case "10:45" *is* in the future.
Clarification: Selecting a time slot that lies ahead another 15 minutes or more (e.g. "11:00", "11:15" ... ) is working fine.
This was discovered by an UCS@school workshop attendee today.
This is somewhat tricky:
the time of browser and UMC server have to be in sync otherwise effects like the message above may occur (the server checks the given distribution time against its local server time). In UCS@school test environments this often occurs after using/reverting to snapshots.
# make sure the execution time lies sufficiently (5min) in the future
if getattr(project, jprop) - datetime.now() < timedelta(minutes=5):
raise ValueError(_('The specified time needs to lie in the future for: %s') %
The code currently requires the distribution time to be at least 5min in the future. If the distribution time is only a few seconds away from real time, the at job may not be called automatically.
I think we should reduce this timedelta to 0 seconds. If the requested distribution time is less than e.g. 65 seconds in the future, the distribution time is moved to rounduptofullminutes(now+65 seconds):
now==10:12:20 distrib_time==10:20:00 → new_distrib_time=10:20:00
now==10:12:20 distrib_time==10:13:00 → new_distrib_time=10:14:00
now==10:12:54 distrib_time==10:13:00 → new_distrib_time=10:14:00
now==10:12:55 distrib_time==10:13:00 → new_distrib_time=10:15:00
now==10:12:57 distrib_time==10:14:00 → new_distrib_time=10:15:00
now==10:13:00 distrib_time==10:13:00 → new_distrib_time=10:15:00
The new distribution time should also be saved at the project file.
Please also alter the collection time code:
a) the timedelta of 10 minutes should be removed
current code: collection - distribution >= 10min
b) the collection time has to be at least 1 min after the (possibly corrected)
The timedelta of 10 minutes has been reduced to 3 minutes (nobody will collect after 2 minutes).
The start time can now be 1 minute in the future.
