Poms says 1.0-SNAPSHOT. Should that be fixed? Thanks -Vincent PS: I think we should have dedicated SVN/Mailing lists for curriki since it's not meant to follow the same practices than xwiki. Also every time curriki makes a commit, it increases the svn revs for xwiki and vice-versa. We need to think about that. Last trunks-devs/ users for xwiki/curriki should be separate IMO.

[xwiki-devs] XWiki needs your help for its continuous build
by Vincent Massol 05 Sep '07

05 Sep '07

Hi everyone, Some of you may have seen that we're now using TeamCity (http:// www.jetbrains.com/teamcity/) for XWiki's continuous build: http://teamcity.xwiki.org The nice thing is that TC allows to distribute the build work to build agents. XPertNet is currently providing one agent on the teamcity.xwiki.org machine. However we've found that the builds are stacking up and are a bit too long to run. Since TC supports parallel builds on different agents we'd like to call the community for help. If you have a machine that has some spare cycles for running XWiki builds then we could hook it up to the teamcity.xwiki.org server to distribute the build load. We don't need that many agents. Probably 1 or 2 (in addition to the one we have) would be enough for starters. Thanks! -Vincent, on behalf of the xwiki dev team _______________________________________________ devs mailing list devs(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/devs

[xwiki-devs] [XEM] Dependencies on XWiki platform for 1.0
by Thomas Mortagne 05 Sep '07

05 Sep '07

Hi xwikiers, Some of XEM actual beta features need XWiki platform modifications. Problem is that XWIKI 1.1 is feature closed and 1.2 will be released too later for the first XEM release. I will comment theses feature here to see what can be done as reduce features, overload platform feature in place of modify etc. 1 – Create wiki from template wiki with includes (in place of copy) on the fly : Jira issues with patch : - http://jira.xwiki.org/jira/browse/XWIKI-1647 - http://jira.xwiki.org/jira/browse/XWIKI-1648 - http://jira.xwiki.org/jira/browse/XWIKI-1646 - Can make just simple wiki copy and postpone the "include on the fly feature" - Can duplicate actual copy wiki process but code copy is always very dangerous 2 – SuperClass and SuperDocument java convenient java classes to manage documents containing xwiki objects : Jira issues with patch : - http://jira.xwiki.org/jira/browse/XWIKI-1685 : can use the actual function with Class.getName() - http://jira.xwiki.org/jira/browse/XWIKI-1576 : can be "hosted" by muliwiki plugin for now 3 – XWikiServer user admin selection : Jira issues with patch : - http://jira.xwiki.org/jira/browse/XWIKI-1666 : can replace user list field by a simple string field 4 – Really delete wiki : Jira issues with patch : - http://jira.xwiki.org/jira/browse/XWIKI-1672 : really delete the database, we can just delete XWikiServer document and let a phantom database 5 – Easier error management in Velocity scripts : Jira issues with patch : - http://jira.xwiki.org/jira/browse/XWIKI-1571 : can be "hosted" by multiwiki plugin for now Regards, -- Thomas Mortagne

[xwiki-devs] [XEM] Automatic installation
by Thomas Mortagne 04 Sep '07

04 Sep '07

Hi all, Before launch the very first version of XEM (XWiki Enterprise Manager) I need to make some automatic installation system. At minimum XEM need : - root wiki which manage wiki farm - default template wiki from which other sub wiki can be created First the actual existing tools to manage package/installation : XE has generic installation system base on HSQLDB and Jetty that simply generate the HSQL database file at build time and package this in installation system. XEM can reuse most of this mechanism except for one part : HSQLDB. This database system can manage only one database which is unusable for multi-wiki purpose. It's mainly on that part I need to discuss what can be done and how. I already made some work around and think of what solutions I see. 1 - First I made an "automatic installation page" that is a root wiki document with attached xar. When that page is rendered, it check if there already exists at least one template wiki and, if not, create it from attached xar. Base on that it will be possible to make maven plugin able to attach XE xar at build time. 2 - Another solution is to work more on installation runtime and to ask user all necessary informations (database host, user, login, etc.) and initialize database with root wiki and all template or sub wiki we need. The first solution strength is that it doesn't depend on the way root wiki is deployed on database (installation init, import xar, etc.) but it load down root wiki with attached xar file and need to always check if XEM is already initialized. I think at long term the two solutions has to be possible but what of these (and other solutions I forget I'm sure) is most useful for other project or much more fast to implement that can be the first step ?
