[xwiki-devs] [xeclipse] questions about LocalDataStorage and display of Page resources
by Jun Han 28 Jul '11

28 Jul '11

Dear All, I have some questions about the LocalDataStorage implementation and Page resources display. 1. The current LocalDataStorage implementation uses xmlrpc model and the cache structure looks like the following: index |-space |-page As the xmlrpc model is being replaced by org.xwiki.eclipse.model package, do we need to modify the local storage as well, e.g., adding a folder to store various wikis? I am not very clear about how local storage works. My rough understanding is like this: (1) When user accesses a page, local cache stores it. (2) Whenever user makes a change in the editor, store it in the local cache (3) when user performs a submission, synchronize the content 2. I have asked how to display page information before, the suggestion from Eduard is the following: ------ WebHome (PageSummary) -------- Attachments ---------- dog.png ---------- spreadsheet.xls -------- XWiki.XWikiComments ---------- 0 : Administrator ('author' property value) ---------- 1 : Guest ---------- 2 : Administrator -------- XWiki.MyClass ---------- 0 : etc. ---------- 1 : etc. However, I am not sure what else needs to be included? e.g, annotations, versions, history, translations? Once confirmed, I will start working on the page content. Best regards Jun Han

[xwiki-devs] The problem with the rest services for autosuggestion.
by 许凌志(Jamesxu) 28 Jul '11

28 Jul '11

Hi, these days I need to implement the rest services for getting suggestion results for link autosuggestion. In my design, I think the suggestion results should be filtered and ranked by the following conditions. (for example user types "[[mytest" in page "xwiki:main.newpage") First [[ is triggered, when user keep typing, the page and attachment suggestion results should be filtered and ranked by the following rules: 1. Prefix matched (only for page name and attachment name) - The pages which are in the same wiki and space of the document current edited.( Prior A) - The pages which are in the same wiki but different space of the document current edited;(Prior B) - The pages which are in different wiki and different space of the document current edited; (Prior C); 2. Partial matched (only for page name and attachment name) - The pages which are in the same wiki and space of the document current edited.( Prior C) - The pages which are in the same wiki but different space of the document current edited;(Prior D) - The pages which are in different wiki and different space of the document current edited; (Prior E) 3. If no page and attachment matches the above two rules, the suggestion box will be disappeared.(eclipse way) However, sometimes user might insert the space name too, for example, user will type "[[Main", following the rule 1 and rule 2, the pages begins with "Main" will be first retrieved as the suggestion results untill user types "." after "Main", the suggestion result will be retreved from the pages under the space "Main" only. Filters still obey the above three rules. And also when user types "attach:", the suggestion result will be retrieved the attachments only following the above three rules. And if the link is under the attachment context, when "@" is typed, the attachments only will be retrieved following the above three rules. In order to do this, I investigated the rest services already existed( http://platform.xwiki.org/xwiki/bin/view/Features/XWikiRESTfulAPI) but I found none is perfect suitable for my needs. So I talk with Marius, he suggested me to use the existed services which are closed to my needs first, and then write the perfect one later. However, I only found the rest service:/wikis/{wiki}/search is the most closed one for the pages suggestion to my needs, there is no attachment search rest service for attachment suggestion, Marius adviced me to use " http://localhost:8080/xwiki/bin/get/XWiki/SuggestLuceneService?outputSyntax…" instead, but I found the search result is in xml format(not json), and also the information of the results got from SuggestLuceneService is limit. I have read the document of how to write custom rest service, but the information is limit, any one can guide me to run an helloworld? -- Best wishes, 许凌志(Jame Xu) MOE KLINNS Lab and SKLMS Lab, Xi'an Jiaotong University Department of Computer Science and Technology, Xi’an Jiaotong University

[xwiki-devs] XWiki Objects via REST
by Martin Bryant 25 Jul '11

25 Jul '11

Dear All: Currently I am trying to create a page with objects via the RESTful interface. We have currently been able to create the page a page with no objects with little to know problems via The REST interface. The problem lies in creating an object of a defined class on a page. We have attempted to use the schema provided by the XWiki Team in the documentation, but have had no real success. The main questions are as follows. . Can we create a page, with objects on them, in a single PUT event? . And what information is mandatory in the XML, to create a object on a page either at the same time, or to add an object to an existing page? Thank you for your time and your response.

[xwiki-devs] hibernate cache optimization?
by Paul Libbrecht 22 Jul '11

22 Jul '11

Hello XWiki-devs, maybe this forum is better than curriki-dev. In short: how can I boost the size of the cache of objects held by hibernate? thanks in advance paul > as you know curriki.org is somewhat of a fat server serving really many requests. > > One symptom we are seeing on the production machine only, almost, is: > xwiki.getPlugin("curriki").fetchUserGroups(). > that sometimes takes more than 1 minute and sometimes much less, all for the same user. > On the development machine it takes time with users with a lot of groups only when the hibernate cache is flushed. > > My interpretation is that this method is fetching the group and probably a lot more. My answer would be to go low-level. > > But another answer would be to ensure that the hibernate cache is big enough so that all these stay in memory. Making this possible would also speed up a huge amount of other things. > > Are we talking of the file ehcache.xml's attribute: > maxElementsInMemory="10000" > ? > I sure could raise this by a factor 10 if true. > > thanks in advance > > paul

[xwiki-devs] [Demo] Wiki3.0 project preview
by Eduard Moraru 21 Jul '11

21 Jul '11

Hi community, If anyone is curious, a demo installation of the current work on the Wiki3.0 [1] research project is available at http://wiki30-demo.xwiki.com With the Workspaces feature, you can register a user and create workspaces, invite/accept other users and generally manage your workspace. Interesting sections (or rather a list of features) are: = In the main wiki = - Create new Workspace (Add menu or homepage button) - Workspace Directory (Top menu, under 'Workspace') - 'Workspaces' section in user profile - User Directory improvements - Join/Leave/Request membership/Accept invitation to join a workspace (Workspace Directory or homepage of a workspace) - Workspace search suggestions (top-right search box) = In a workspace = - Dashboard - Workspace information panel (right panels) - Main wiki link (Top menu, under 'Workspace') - Delete workspace (Top menu, under Workspace, for owner) - Workspace Configuration section (Administration, 'Configuration' category) - Workspace Users section; Accept membership requests or invite users (Administration, 'Users & Groups' category) - User registration redirecting to main wiki (Top-Right register link) - Removed local XWiki.Admin user Besides the Workspaces feature, the Real-Time editor is also available for a quick test. You can access it by editing a page in "Real Time" edit mode. You can't miss it :) For quick tests, you can edit the same page in 2 browser windows and see changes in one window triggering an update in the second one. It also works with multiple users (obviously) and allows other to join in the editing session. For now it's working real time only for wiki code. Work on the WYSIWYG version has already started. Please feel free to report any bugs or suggestions here or (preferably) at http://jira.xwiki.org/jira/browse/WIKITHREEDOTO and do be aware that it's still work in progress. Thanks, Eduard ----------------- References: [1] https://wiki30.xwikisas.com/

[xwiki-devs] [UX] Tips&Tricks
by Ecaterina Moraru (Valica) 21 Jul '11

21 Jul '11

Hi, I was thinking about what tips and tricks XWiki has, things that are not really that well documented but that are very productive and fun. Would be nice to have such an inspiring thread from which we could learn a lot and, why not, have fun experimenting :) If the thread is really useful we could also integrate these tips more clearly in our documentation or also we could have a tips panel inside XWiki Enterprise, for beginners/intermediate users. The tip structure could be: *Title: ** Level: ** Target: * *Description:* Thanks, Caty* *
