issue #1580 Add last calculated cache size to Dashboard Storage chart
Size of cached files with all derivatives and representatives may be
as large as all image files, actually doubling the needed storage
size. So it may be nice to see it represented in the storage
chart, if one remembers to occasionally recalculate it under
Tools -> Maintenance..
Also make it possible to deactivate this setting.
This algorithm does not work for Windows and when "exec" is disabled. But not having this cache size is not a major issue. What is a problem is when calculating the cache size breaks the execution, which must be avoided.
* make the biggest part of aggregations in the database directly
* use a 5 minutes cache in user session
This cache is not optimal. No reason to make it specific to the user session, no reason to
recalculate previous days each time. To be improved. It was urgent to find a fix for
Piwigo 11.1.0.
+ add a 5 minutes cache to avoid calculating cache size too often
