[xwiki-devs] [Brainstorming] Stop adding stuff to oldcore because "new modules shouldn't depend on oldcore"?

by Vincent Massol

Hi devs, I see that we keep adding stuff regularly to oldcore and the reason is "my code depends on oldcore so I cannot depend on oldcore in new modules". First, this is not completely true. We have several modules that already depend on oldcore. Also we cannot wait indefinitely that the new model magically appears (that won't happen… :)). I think it's fine to depend on oldcore when a new module requires to use the model and when the bridge (DAB) is not enough. However we need to be careful about one thing: that oldcore itself doesn't use that new module. So sometimes it will mean extracting stuff from oldcore into a separate module so that it can use the other new module ;) Personally I now think we need to continue splitting oldcore and it's more important that we create new modules for specific domains, even if they use old code and even if they use the com.xpn namespace when moving oldcode) than keep everything as it is and make oldcore grow fatter… Of course sometimes it may just be too complex but at least we should consider it and when possible create new modules depending on oldcore. WDYT? Thanks -Vincent

[xwiki-devs] [VOTE] merge branch 'feature-customizable-user-directory' (enterprise and platform) into 'master'

by Eduard Moraru

Hi devs, I`ve worked on allowing the customization of the User Directory and, implicitly, the ability to search for users in a wiki. The jira issue [1] has 3 attached images, but I am going to link them here [2][3][4] too for commodity. The idea is simple: Use the livetable to display users (pages with XWikiUsers objects in them) and display a selection of extra columns (XWikiUsers class property names) that are stored in the user's profile page as preferences. Each user can define his/er own view over the user directory and can also reset it to default. This feature comes as a complementary to the previous one [5] (that is still waiting for your votes, BWT :) ). Combined, the two allow an admin to display newly added user fields in the user's profile and other users to perform user searches based on (and not only) these fields. The only inconvenience with this approach is related to the workspaces application in the way that a workspace has a different membership relationship (membership to the workspace's group) than a normal XE instance or a farm subwiki (pages with XWikiUsers objects in them). Please see the jira issue [6] about this inconvenience and also the chosen and implemented solution (with an example). I`d like your vote if this is a feature that is to be integrated in XWiki, as proposed by the 2 pull requests [7][8] that are available. Thanks, Eduard ---------- [1] http://jira.xwiki.org/browse/XE-1131 [2] http://jira.xwiki.org/secure/attachment/24775/customizableUserDirectory-def…, no customization, default columns) [3] http://jira.xwiki.org/secure/attachment/24776/customizableUserDirectory-cus… screen) [4] http://jira.xwiki.org/secure/attachment/24777/customizableUserDirectory-cus… with extra columns added) [5] http://xwiki.markmail.org/thread/22snpab3czfdexln (mail: [VOTE] merge branch 'feature-user-profile-information-editor' into master in 4.0M2) [6] http://jira.xwiki.org/browse/XWIKI-7648 (workspaces issue with the implemented solution) [7] https://github.com/xwiki/xwiki-enterprise/pull/18 [8] https://github.com/xwiki/xwiki-platform/pull/42

[xwiki-devs] Problems with PreemtiveLock

by Andreas Jonsson

Hello, I tried to build all modules under xwiki-platform-core, but the build process hanged on PreemtiveLockTest, so I had a look at the code and noticed some problems: 1. PreemtiveLockProvider.lockBlockingThread is concurrently accessed and updated despite being an unsynchronized HashMap. It must be synchronized. 2. The deadlock recovery algorithm is "if there is a deadlock, ignore the fact that the lock is locked and proceed." To me this seems unintuitive. When a deadlock is detected, an exception should be thrown and the thread aborted. 3. Presumably, the thread which is deprived of its lock is supposed to at least be blocked until the thieving thread unlocks the lock, but there is a race condition so both threads may run simultaneously. 4. Related to 3., the 'owners' stack in the lock is concurrently accessed without synchronization in 'currentThreadOwnsAllLocks'. As of deadlock detection, do we really need it? If so, would java.lang.management.ThreadMXBean.findDeadlockedThreads() be sufficient? In my opinion, the implementation PreemtiveLock should be discarded and the LockProvider should return an ordinary ReentrantReadWriteLock. Best Regards, /Andreas

[xwiki-devs] gsoc 2012

by Melania Galea

Hi there! My name is Melania Galea and I am a student in Romania. I have worked with OpenNMS for gsoc 2011 on the "Converting OpenNMS to use Hibernate" project. The experience was amazing, I learnt a lot about working on a real-life application inside an open source community. I am a pasionate Java developer who promotes the benevolent sharing of knowledge. As far as my technical experience goes, I enjoy working both on the backend and frontend sides of an application. I have worked with java and many others integrated technologies such as Spring or Hibernate, as well as with several Java-based web frameworks such as Wicket or Spring MVC. I have currently discovered a passion for node.js and javascript as together with my friends I developed a customized IRC application. From the projects you proposed for this year's gsoc, the "Annotations for images and other content types" project was the most appealing to my skills. I would very much enjoy working on this XWiki module. I hope we will work together this summer. Thank you, Melania Galea

[xwiki-devs] Postpone 4.0M2 release by 2 days to Wednesday 28th of March 2012

by Vincent Massol

Hi devs, Eddy has 3 pull requests active that I think we should include for 4.0M2: * User profile customization * User directory customization * Annotation/Comment merge I'd like to propose to delay the 4.0M2 release by 2 days (from Monday 26 to Wednesday 28) to allow us to accept them and release them. IMO we need to do this since we want to have max feedbacks about them, especially the annotation/comment merge which includes a migration. WDYT? Thanks -Vincent
