Bug Description

When using Google Calendar plugin to create an event, the new event is returned but not indexed immediately in the universe so all the calendars won't contain such a event until next time universe gets updated.

A manual update might be needed as the last step of New Event action.

Plugin Name: Google Calendar
Plugin Version: v1.5

Is is more of a Do bug.

status: New → Confirmed

Plugins need a simple way to tell Do that new items have been created and should be added to the index immediately. A good way to provide this ability to plugins would be a method on CoreService.

I recently have realized by calling the actually updating function at the last step in a plugin is not a good idea, because this will hide the changes of the item source from universe manager. It might be OK if items are just get modified or added, but if any item is removed and the list is updated before universe manager notices it, the item will stay in the universe for ever.

So currently the only way to let universe manager know an item is removed is to wait until the next update, this is really unfriendly to user because in some circumstances users may want to see changes immediately.

I added a branch to propose an ReloadItemSource method from Services.Core, which will allow plugins to update a specific ItemSource specified using the class' FullName. e.g. ReloadItemSource (typeof (GDocsItemSource).FullName);

I would like to know whether is there a better way to pass the identification of an ItemSource to core service, the current one feels a bit dirty.

Why not just give the type as parameter?

We've talked about this a number of times, we will not have a method to
allow itemsources to refresh their universe. It's not the correct way to
solve the problem.

Can't we use inotify on the "watched" directories?

Do 0.9 will include new API to allow plugins to do this.

Plugins which want to use this will need patches to transition to DynamicItemSource.
