Re: [xwiki-devs] How to deal with statistics duplications

That's one of the main difference between action solution and parameter solution: you don't have anything do here with action solution because statistics module simply don't know about this action and don't listen to it so it's not the same kind of complexity. With parameter solution you need to introduce two new API (the parameter and the context value) that should be taken into account everywhere where action is just a kind of plugin. The only good point about this one is that we don't introduce anything new publicly but apart from this i don't like it very much. It does not cover properly our use case, we don't want to avoid statistics for an ajax query that would delete an object for example, that's a valid user action (done using ajax but still a user action). So to summarize IMO the action solution is the safest and easiest solution for the use cases we currently have which are internal queries (mostly ajax). > > Thanks > -Vincent > >>> Thanks >>> -Vincent >>> >>>> Jerome" >>>> >>>>>> >>>>>>> I think I'd prefer a more explicit param. >>>>>>> >>>>>>> Thanks >>>>>>> -Vincent >>>>>>> >>>>>>>> On Thu, Nov 19, 2009 at 12:04, Thomas Mortagne >>>>>>>> <thomas.mortagne(a)xwiki.com>    wrote: >>>>>>>>> On Thu, Nov 19, 2009 at 11:36, Vincent Massol<vincent(a)massol.net> >>>>>>>>> wrote: >>>>>>>>>> >>>>>>>>>> On Nov 19, 2009, at 11:26 AM, Thomas Mortagne wrote: >>>>>>>>>> >>>>>>>>>>> On Thu, Nov 19, 2009 at 08:50, Vincent Massol<vincent(a)massol.net >>>>>>>>>>>> >>>>>>>>>>> wrote: >>>>>>>>>>>> >>>>>>>>>>>> On Nov 18, 2009, at 5:16 PM, Thomas Mortagne wrote: >>>>>>>>>>>> >>>>>>>>>>>>> Hi, >>>>>>>>>>>>> >>>>>>>>>>>>> Since we introduce document footer informations view >>>>>>>>>>>>> statistics >>>>>>>>>>>>> are >>>>>>>>>>>>> store several time for the same user view of a page. >>>>>>>>>>>>> >>>>>>>>>>>>> See http://jira.xwiki.org/jira/browse/XWIKI-4590 >>>>>>>>>>>>> >>>>>>>>>>>>> The issue is that theses tabs are loaded asynchronously in >>>>>>>>>>>>> ajax >>>>>>>>>>>>> and >>>>>>>>>>>>> make a call using view action. >>>>>>>>>>>>> >>>>>>>>>>>>> Here are some solutions: >>>>>>>>>>>>> 1/ introduce a new action "viewinternal", "service" or >>>>>>>>>>>>> anything >>>>>>>>>>>>> else >>>>>>>>>>>>> that would be a "view" action without UI and not taken into >>>>>>>>>>>>> account by >>>>>>>>>>>>> statistics (that register for "view" action events) >>>>>>>>>>>> >>>>>>>>>>>> +0 >>>>>>>>>>>> >>>>>>>>>>>>> 2/ pretty much the same thing that 1/ but based on a URL >>>>>>>>>>>>> parameter >>>>>>>>>>>> >>>>>>>>>>>> +1 >>>>>>>>>>>> >>>>>>>>>>>> This is much better to me since: >>>>>>>>>>>> * Stats are a transersval concern, not related to the view >>>>>>>>>>>> action >>>>>>>>>>>> especially.
