[xwiki-devs] XWikiDocuments not thread safe added to XWikiCacheStore
by Fabian Pichler 18 Aug '16

18 Aug '16

Hi devs http://jira.xwiki.org/browse/XWIKI-13623 I would like to discuss the suggested solution, before I start implementing it: *I suggest the following solution:* Introducing a nested DocumentLoader class which loads the document calling the basestore loadXWikiDoc in a synchronized getDocOrLoad method. The DocumentLoader objects gets instantiated in the cacheStore on a cache miss. It then gets stored in a ConcurrentHashMap using the same key which is used for the document cache (DocumentReference including language). Using putIfAbsent to insert the DocumentLoader and calling the synchronized load method on the object in the map solves the memory visibility issue and moreover ensures that the same XWikiDocument is not loaded multiple times concurrently from the database. It is still possible to load different documents in parallel. A DocumentLoader will load the XWikiDocument only once and the returns the identical document object on any following call of the synchronized getDocOrLoad method. WDYT? Kind Regards, Fabian

[xwiki-devs] [GSoC] [Reminder] Final evaluation deadline is August 23 19:00
by Eduard Moraru 17 Aug '16

17 Aug '16

Hi, Fitz, As you probably know (from Google's mail), the final evaluation is coming up. We`d like you to start getting ready for it and let us know what you have been up to in the last period. As Google suggests, it would also be a good idea to ask for some feedback before submitting the final evaluation and URL to the work done (from your part), just to make sure everything is in order. It would also be a good idea to resume communication, since it`s been a bit low lately and we are not getting enough feedback from you recently. Hope to hear from you soon! -Eduard

[xwiki-devs] Issue with installed count on e.x.o overflowing the AS + too many versions
by Vincent Massol 15 Aug '16

15 Aug '16

Hi Thomas and all, Back from holidays! :) I’ve noticed that the new feature of counting installed extensions on e.x.o is having a drawback: it saturates the activity stream, making it very hard to see real edits by users. Every day the scheduler modifies lots of wiki pages to set the new install count. See for example: http://www.xwiki.org/xwiki/bin/view/Main/News I think a simple change would be for the scheduler to make modifications as minor edits. This should prevent the edits from being visible in the AS. WDYT? Now this is going to cause another real issue very soon: pages will soon start to have a lot of revisions and we know this is currently a performance issue. It’s also hiding real edits in the history making the history a bit less clean. I guess an option would be for the scheduler to delete the last revision after it updates a page. Although not very nice, it could work for now. WDYT? Thanks -Vincent

[xwiki-devs] Event for document loading?
by Vincent Telleria 11 Aug '16

11 Aug '16

Hello XWiki devs, I was wondering if there is an Event which gets published when an XWikiDocument first gets loaded, or a good way of adding such an event? I have been looking for such an event, but one does not appear to exist and to add one looks like it would require making changes to the XWikiHibernateStore to have it fire events on load. I am looking for a way to intercept documents when they are first being loaded so I can populate some of their objects from an external source and avoid the issue of having many joins when working with documents with a large number of objects. My other thought is to use a custom hibernate mapping to get this data for a custom table I can populate in other ways, but I would prefer the event driven approach. Thanks! ~Vincent

[xwiki-devs] [ANN] VelocityContext versus ScriptContext
by Thomas Mortagne 01 Aug '16

01 Aug '16

Hi devs, I finally started the long waiting refactoring to deal with conflicting ScriptContext and VelocityContext. * they are now fully in sync (at least that's the goal when you use them properly :)) * VelocityContext moved to a more internal thing or at least very specific (use case where you execute yourself some Velocity code). In general if you want to set or access script bindings, do it trough ScriptContext. * new ScriptContextManager#getCurrentScriptContext which directly return a not updated ScriptContext. To be used when you want to set binding mostly and you don't care if it's up to date or not. If there is any chance you access anything in the script context it's safer to use #getScriptContext So if you have weird behavior with Velocity variable you know who to blame. Please report me anything that looks wrong on this area. -- Thomas Mortagne
