[xwiki-devs] listener not reloading after modification
by Cecile 17 Nov '12

17 Nov '12

Hello everyone, I'm trying to write a listener. The listener is correctly triggered after creation. But when I change the listener code, it is not taken into account by the server. I have to restart the server. How to avoid this? This my code: {{groovy}} import org.xwiki.observation.* import org.xwiki.observation.event.* import com.xpn.xwiki.web.* import com.xpn.xwiki.* class AutoEventListener implements EventListener { def xwiki def context AutoEventListener(xwiki, context) { this.xwiki = xwiki this.context = context } String getName() { return "auto_febi" } List<Event> getEvents() { return Arrays.asList(new DocumentSaveEvent()) } void onEvent(Event event, Object source, Object data) { if (source.fullName != "EventListenerAuto") { def document = xwiki.getDocument(source.fullName) def var= document.getValue("avisDSI") if (var != "-"){ document.set("nomDSI","coucou")} } } } def observation = Utils.getComponent(ObservationManager.class) observation.removeListener("auto_febi") def listener = new AutoEventListener(xwiki, xcontext) observation.addListener(listener) {{/groovy}} Thank you very much for your future answer, Cécile -- View this message in context: http://xwiki.475771.n2.nabble.com/listener-not-reloading-after-modification… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] Blank Xwiki after upgrading from 2.7.33656 to 4.3-milestone-1
by echocoder 16 Nov '12

16 Nov '12

I am upgrading from Xwiki 2.7.33656 to Xwiki 4.3-milestone-1. I also upgraded from Tomcat 5.5.33 to Tomcat 7.0.32. I installed the Xwiki as a WAR in the new instnace of Tomcat. I modified the hibernate.cfg.xml file as indicated in the install instructions. When trying to access the new Xwiki it just sits on a blank page with reference to http://localhost:8080/xwiki/bin/view/Main/. I did try to run the MYSQLDUMP file from the older Xwiki instance in the newer Xwiki instance. But each time it fails with "lost connect to mysql". Is there some difference between the MySQL databse instances of Xwiki 2.7.* and Xwiki 4.3* that could be causing this problem? Some of the log files are below... *catalina*.log *Nov 14, 2012 11:24:24 AM org.apache.catalina.startup.Catalina start INFO: Server startup in 29542 ms *localhost_access_log* 0:0:0:0:0:0:0:1 - - [14/Nov/2012:11:41:36 -0600] "GET /xwiki/ HTTP/1.1" 302 - 0:0:0:0:0:0:0:1 - - [14/Nov/2012:11:41:36 -0600] "GET /xwiki/bin/view/Main/ HTTP/1.1" 200 - *localhost.log* Nov 14, 2012 11:23:55 AM org.apache.catalina.core.ApplicationContext log INFO: ContextListener: attributeAdded('org.apache.jasper.compiler.TldLocationsCache', 'org.apache.jasper.compiler.TldLocationsCache@2b9406') -- View this message in context: http://xwiki.475771.n2.nabble.com/Blank-Xwiki-after-upgrading-from-2-7-3365… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] Thoughts on new model proposal
by Caleb James DeLisle 16 Nov '12

16 Nov '12

Hi, I took a look at the new model proposal and there are a few questions and suggested changes. https://github.com/xwiki/xwiki-platform/blob/feature-newmodel/xwiki-platfor… Should this be a String rather than a Java UUID type? https://github.com/xwiki/xwiki-platform/blob/feature-newmodel/xwiki-platfor… If we use getChildren() rather than getChildReferences(), we will be mangling the model with the database code which violates the MVC principle. Also we run the risk of encouraging users to walk the tree looking for the entity it wants rather than creating a reference to it and using that. Walking the tree would obviously incur enormous unnecessary database load. https://github.com/xwiki/xwiki-platform/blob/feature-newmodel/xwiki-platfor… Do we want to continue with the concept of the global variable representing the "current" document? I'm currently not brimming with alternative ideas but the heavy reliance on the XWikiContext has lead to a lot of inter-modular communication which makes oldcore difficult to maintain, perhaps we can prevent this in the new model. https://github.com/xwiki/xwiki-platform/blob/feature-newmodel/xwiki-platfor… I would rather this have a name which doesn't collide with a java.lang class. When I see Object in a .java file I would like it to always mean java.lang.Object. https://github.com/xwiki/xwiki-platform/blob/feature-newmodel/xwiki-platfor… I like XClass better for this purpose, it is essentially a class and creating a new name which nobody has ever heard of will just steepen the learning curve and make things hard on newcomers. https://github.com/xwiki/xwiki-platform/blob/feature-newmodel/xwiki-platfor… Why not give the user direct access to the property without the intervening wrapper? https://github.com/xwiki/xwiki-platform/blob/feature-newmodel/xwiki-platfor… I don't like this. A Persistable is saved in a store by a user. Who is the user and where are they saving it? What if I want to have multiple stores? Must there be a global variable representing the store which is implied by this function? The comment and minorEdit fields are also a bit dubious, perhaps in the future they will make no sense, perhaps they should really be attributes of the Document, also the "attributes" parameter reminds me of this: http://geek-and-poke.com/2012/06/how-to-create-a-stable-api.html Finally, giving the document awareness of where and how it is stored violates the MVC boundries. I think we should not worry about the API which stores the Persistable when we are creating the model, the store API should be separate so that it can evolve while the model stays stable. https://github.com/xwiki/xwiki-platform/blob/feature-newmodel/xwiki-platfor… A session is essentially a transaction? If so why not call it Transaction? Also why does it extend Persistable? How do you persist a session? https://github.com/xwiki/xwiki-platform/blob/feature-newmodel/xwiki-platfor… Why does addSpace() not take a Space parameter? it makes sense to me that you would do: parent = storeApi.get(wikiRef, "SomeSpace", user); child = new DefaultSpace(); child.addDocument("ADocument", new DefaultDocument("This is content.")); parent.addSpace("ChildSpace", child); storeApi.save(parent, user); I'm just brainstorming here but this seems like a reasonable approach.. I noticed the lack of a User data type, is that just something which is planned for the future or is it intentionally missing? Thanks, Caleb

[xwiki-devs] [VOTE] Create new xwiki-platform-application/ module
by Vincent Massol 14 Nov '12

14 Nov '12

Hi devs, I'm writing functional tests for the FAQ app in platform and I wanted to write a test for verifying that the app registers itself in the app panel. The problem is that the app panel requires UI extensions and the app panel is currently located in the panels app. However I don't want to put that as a dependency on UI extensions in the panels app since no other panel need it. So the good answer is that the app panel is not correctly located. Actually the panels ui app should only contain the Panels.WenHome page and all other panels should be part of the other functional domains… So that brings me to this proposal which is: * Create a new xwiki-platform-application/ which represents the functional domain of wiki applications. * Have 3 submodules in it as follows: xwiki-platform-application/ |_ xwiki-platform-application-manager/ |_ xwiki-platform-application-manager-api/ |_ xwiki-platform-application-manager-ui/ |_ xwiki-platform-application-appwithinminutes/ |_ xwiki-platform-application-ui/ * ATM xwiki-platform-application-ui/ would contain only the Applications Panel but in the future the content of xwiki-platform-application-manager-ui/ should be merged with it and it should for example provide a UI to list all apps in the wiki. * In the future xwiki-platform-application-manager-api/ would also be renamed in xwiki-platform-application-api/ Here's my +1 Thanks -Vincent

[xwiki-devs] [VOTE] Add CLIRR exclude for 2 new methods in the workspace interface for 4.3M1
by Eduard Moraru 14 Nov '12

14 Nov '12

Hi devs, Since the current policy is to ask before adding a CLIRR exclude and since I did not ask when I applied GuillaumeD's pull request [1], I hereby ask for your vote whether it is ok to exclude the 2 new methods: - that allows the creation of workspaces using a different template than the default one - that lists workspace templates Since we are tight with time (Fabio needs to finish the 4.3M1 release), this issue should be settled ASAP. Also, please note that the Workspace API is still young (and pretty basic), as far as I am concerned, and it is bound to get updated in the future. Here's my +1 Thanks, Eduard -------- [1] https://github.com/xwiki/xwiki-platform/pull/70

If you do a join (all active repos) you still have it. I do not know what you means by joining all repos, but I would be surprise to see the IDE find its way between them.

If I had to implement it, I will probably use some hashing method to be able to recognize similar commits, since there effectively no link between them.

Until we have Git, there were no better way. This does not means that we should not improve our practice.

It's just a question of tools since the history is not lost. It's still there in our active repos. There is absolutely no link between these histories. It is not only a question of tools. Moreover, requiring querying all active repositories to have a proper history completely defeat the purpose of having separate repositories. I do not see the comparison with my remark above. Git has been made for versionning, not for statistics, it is not my fault. > > > So the general rule for me is: Copy history when the source repository is > >> removed/deleted/not used anymore. > > How many times have you done this? I believe 0 times since I don't think you'd be so much in favor if you had tried it. I suggest you try it a few times on your own projects first :) It's really hard to do it right and very time consuming. When I have copied the security component from contrib, I have done so. I hope that I am not alone.

Again we're not loosing history. If a repo is removed then its history is copied I agree about that.

Even Git itself doesn't follow the history when you move stuff around. Said differently it's alwasy possible to find the history but the IDE and "standard" tool don't follow it. It does so far better since we move to Git and it is really a valuable tool.

Prove me that is more cost than the one newcommers has to enter the project. Maybe you do not value history so much because you have by your own experience of the project a good knowledge of what happen in the past. When I dig in some code, I always found history valuable to understand why that piece of code is not written the way I may have expected and why I should not got that way. If Thomas conclude it is too hard to be done, and not just some developer's lazyness, I would understand; but I do not agree that it should not be done just because it breaks statistics or we think it is too hard. This is why I suggest a tools that do it once for all. I would be really disappointed of Git if we had to conclude this.

[xwiki-devs] Community development and Marketing FOSDEM DevRoom
by Sergiu Dumitriu 13 Nov '12

13 Nov '12

This is an official call for sessions for a "Community development and Marketing" devroom, hosted at FOSDEM 2013 on Saturday, February 2nd. In this devroom, developers with different profiles and backgrounds are invited to brainstorm about aspects related to software projects which are beyond the code itself, but nevertheless crucial for keeping the project alive, such as marketing strategies useful for attracting users and contributors, processes for managing the dynamics of the community, and open source solutions for project lifecycle management. While Marketing and FLOSS have long been considered incompatible concepts, recent history has shown that marketing strategies properly tailored for the FLOSS world can be of real help for open source projects without tainting their ideology. Good marketing can be an essential instrument for reaching out and expanding the community of users and contributors. You are invited to showcase best practices and successful collaborations between marketers and developers, to discuss marketing in a typical hacker environment, and to participate in establishing a link between communities and in creating opportunities for collaboration. Furthermore, you are invited to exchange ideas about what works for keeping a community in shape: how to encourage contributions from new members, how to keep people motivated, how to work across time zones and cultures, how to handle conflicts, what are the processes for naming new committers or for accepting patches. Presenters can talk about their favorite combination of tools for version control, code review, continuous integration, issue tracking, documentation, as well as full infrastructure setup scenarios. It will be a great environment for learning from individual success stories about new ways of working better inside an open source community. If you are interested in holding a session, please submit your talk proposal no later than 23-12-2012 (UTC) by sending an email message to cdm-devroom(a)lists.fosdem.org, and providing the following information: About the speaker: - Name - Affiliation (if any) - Short bio About the proposed session: - Title - Abstract (no more than 300 words) - Preferred duration (5, 15 or 30 minutes) and time slot (optional) You can also subscribe to the mailing list to discuss the devroom topics with the two organizers, by sending an empty email message to cdm-devroom-subscribe(a)lists.fosdem.org. Looking forward to your contributions, Italo Vignoli (italo(a)italovignoli.com) Sergiu Dumitriu (sergiu(a)xwiki.org)
