[xwiki-devs] [XEM] Dependencies on XWiki platform for 1.0

by Thomas Mortagne

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

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 ?

[xwiki-devs] multi-wikies environment

by Miriam Natanzon

Hi all! I'm a programmer in an educational association called “Snunit” which located in Jerusalem, Israel. We want to create multi-wikies environment, such that every teacher can create his class's wiki. I want to build it, in one db. I think to add column of "wiki_id" to each relevant table, and in that way to hold the data about all the wikies. Is XWiki database support many wikies? (Without creating db for each specific wiki) Thank you! Miriam N. _______________________________________________ devs mailing list devs(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/devs

[xwiki-devs] Passing arguments to a page to set IFrame source

by Ricardo Pinto

Hello! How can I pass some arguments to a wiki page? I'd like to have a page with a list of objects of the ApplicationClass (with some properties like Name, Description, Version, Type, Url/Path, etc.). Then there will be a button for each one that will redirect to a new page, passing the name and url/path of the chosen app. In this new page I'll have an iframe, for instance, that will show the web app according to the passed url (for local apps it could somehow launch the app), as well as a "AppFinding" ClassTemplate form for create new objects. What do you think? Again a plugin could be the better way of doing this... Thanks in advance for your help :) Best regards, Ricardo. _______________________________________________ devs mailing list devs(a)xwiki.org http://lists.xwiki.org/mailman/listinfo/devs

Something like: "Failed updating schema while executing query [" + sql + "]" * I think we need to pass "e" and not "e.getMessage()" so that we log the wrapped exceptions if any and get to the root of the problem. Especially as this is an error and I think we need to have stack traces for errors. So I propose something like: log.error("Failed updating schema while executing query [" + sql + "]", e); WDYT?

[Proposal] Make XE the default maven build profile

by Sergiu Dumitriu

Hi, The current default profile, when building trunks-devs or trunks-users, is to build all components, including curriki, XEM, multiwiki. There is a profile defined for building only XE, but it is not the default one. Given the fact that most users only want to build XE, this should be the default profile. So I'd like to: - make the default profile = 'xe' - add an 'all' profile, which builds all the modules WDYT? Sergiu -- http://purl.org/net/sergiu
