The memory leak was only perceptible with large dataset... Each time the
calendar view is call there is a memory build up until saturation... So I
gues that it could happen when web2py is not restarted during a certain
periode and calendar view is call many many time with a smaller dataset...
You could use web2py feature to generate data and investigate if the leak
is still there, or you can check the date of the app build... If it before
january 2013, there surely still a memory leak...
I can provide a code sample for a json feed function, but you will need to
adapt to suit your need...
Here an example :
*# Controller*
def calendar():
a='' # empty view only to allow to create a callable view to initialize
the FullCalendar plugin
return dict(a=a)
def calendar_json_feed():
rows=db(db.your_table.id>0).select(db.your_table.id,
orderby=db.your_table.order_field_if_required, cache=(cache.ram, 86400)) #
1 day = 86400 sec
# Order issue solve by order in FullCalendar. There is a specific
order issue with chrome :
https://code.google.com/p/fullcalendar/issues/detail?id=379
# To workaround Chrome specific issue I could increment start time
of event of 1 sec
events = []
for i,row in enumerate(rows):
events.append({'title': id_represent[row.id],
'allDay': False,
'start': row.date.strftime('%Y-%m-%d 08:30:00'), # Leading zero

return simplejson.dumps(events)

Since I save you a lot of time you can consider to update the
AppointmentManager app with this example to return to community :
