Hello friends, Just wanted to say, I figured out the issue with my changes not loading. the macros.vm was getting cached. I put the following lines in xwiki.properties to stop it. velocity.properties = file.resource.loader.cache = false velocity.properties = velocimacro.library.autoreload = true I hope this is the best solution. Thanks JS

[xwiki-devs] Fwd: [GSoc] XDroid Platform

by sasinda rukshan

---------- Forwarded message ---------- From: sasinda rukshan <sasindarukshan(a)gmail.com> Date: Mon, Jun 18, 2012 at 2:56 PM Subject: Re: [xwiki-devs] [GSoc] XDroid Platform To: XWiki Developers <devs(a)xwiki.org> Hi Thomas, Thanks for the explanations. The methods toXML , toEmbedXML are wrong.It was just an idea that came up without much thinking. I will use a separate model converter.(xwikitTosimpleModelConverter implements ModelConverter like thing). So the model objects don't know about it at all. By what you ment by "user" I think it is the client app developer is it? you did not mean end user. I never reveal the xml representations to end users. I came up with a simpler design. I will post diagram later tomorrow. To give a brief on it, XObject : has protected property List<XProperty> |__XPoperty :<< all objects that can be added as a property of an objects should extend this. Has an attribute list. cancels the | property list of XObject | |_____XString : |__Abstract XDocObject :<< all documents should have an object of this. This is the pages class. Has a object List<XObject> | |____XBlog :<< all documents which are blogs should have a object of this. This determines the class of the object. | but this data is not posted anywhere in <link rel="...../class"> . It is just kept for type checks. That is like | this page should include XBlogPost objects. |__XBlogPost : <<the BlogPostClass object. In my view I assume every page has an object of some class. And this object holds the objects which you can get under .../pages/BlogPg1/objects/ [ an added advantage: I think we can make a ViewEngine to generate android View components from the above model. Since the objects in the page carry rendering descriptions.We can make a general model like a browser to brows xwiki using generated the views. But the problem is some features in specific spaces like blog do not seem to be totally defined by the XWiki Object model behind them. Also this is just an idea (not suggesting I do for the GSoc).Making it a usable reality is a little challenge. ] So as you said if a document (I think it equivalent to a page) can have many class types my assumption fails. Why should a document be of multiple classes. I was thinking a page belongs to a class. And the page is an instance of that class. If page can have multiple classes my understanding should be wrong. Isn't it?

[xwiki-devs] Clover TPC values for Commons/Rendering/Platform/Enterprise

by Vincent Massol

Hi devs, I've finally spent the time to measure our TPC (Test Percentage Coverage) using Clover. The reports are very interesting and show where we need to spend our efforts in testing (be them automated or manual). Here are the raw top level results: =========================== All results: http://maven.xwiki.org/site/clover/20120701/ * Only Commons (this means unit tests and integration tests in the commons repository only): 62.4% * Only Rendering: 75.5% * Only Platform: 36.8% * Commons+Rendering (ie Rendering tests exercise also Commons code): 72.1% * Commons+Rendering+Platform: 47.4% * Commons+Rendering+Platform+Enterprise: So our code is roughly tested at X% (note that 100% TPC doesn't mean the code is working, it means each line of code has been tested in some way but it doesn't mean all combinations have been tested!). A good value is between 70-80%. We're actually better than I thought (I had 50% or lower in mind) :) However there are huge disparity with code having 90+% and code having 0% coverage (402 classes have 0% coverage!). Quick high level analysis: ==================== * Commons is missing quite a lot of unit tests * Wikimodel in Rendering is dragging the TPC down, I think we were above 80% before we included WikiModel) * Platform has a very low level of unit tests which means it's easy to break stuff in platform and it's hard to verify that what we add in platform works well in general (means going through longer stabilization phases than needed) * Our functional tests are quite effective (even though they take a very very long time to execute) since they make the TPC go from 47% to 63% for Commons+Rendering+Platform. The bad TPC for Platform is probably improved by the functional tests. Next steps ========= * IMO all developers need to look in details at the results and familiarize themselves with the Clover reports * Each dev should look at stuff he has coded and ensure that they have a good level of unit tests * All new code should get at the very minimum between 70-80% unit test coverage. For example the new diff module in commons only has only 43.4% coverage which is far from enough * Spend time to automate the generation of these reports. We need a dedicated agent for this since it "contaminates" the local repository with clovered jars. The overall generation time is around 4-5 hours. * Dig more around the reports to identify functional areas of XWiki missing automated tests. These areas must be covered by manual testing at each release. * Decide if we want a more rigorous strategy for new code, and how to get alerts for modules missing coverage. WDYT? Let's share your analysis in this thread so that we can brainstorm about what to do with these reports Thanks -Vincent

[xwiki-devs] [Idea] Bundle jQuery ?

by Jerome Velociter

Hi devs, Now that all the scripts on the Internets are implemented as jQuery plugins, should we bite the bullet and make it easier for extensions developers to integrate such scripts ? Note it would not necessarily mean we use it ourselves in web/XE. If we don't do something about it, there is the risk that many extensions bring their own jQuery to the party, which will translate in slower page loads and more importantly a less enjoyable extension developer experience. An alternative idea would be an "official" jQuery extension (with a JSX) that other extensions can depend upon, should they need jQuery. What do you think ? Jerome

Re: [xwiki-devs] [GSoC] Responsive Skin

And in a wiki they can have spaces and etc... > Well the first time I used XWiki my intuition was to use the drop down at > space to get a list of spaces.I thought the document index would list the > spaces available. Ah ok, I think I understand what you mean. Clarify if I am wrong: on the bread crumb, you think that it would be a good idea if it listed the adjacent areas in the drop down. eg. if you hover over the pages, it will reveal all the pages in the same space as the current document. As a status update. I've done most of the mobile of the skin. Go ahead and try it in your respective browser: http://jssolichin.com/xwiki. I have presently tested it on android and Windows Phone along with browser resize on Chrome. Trying to get my hands on some iphone/blackberry. Let me know any glaring issues on those browsers in the mean time. What do you guys think about my implementation/solution to the sidebar? I handled the swiping a bit differently than the Coffin example. The issue with coffin is that it seems that it is not cross compatible. The swipe gesture does not work on WP7 nor on a browser. If you load coffin in a browser with a small viewport, you lose the ability to scroll completely and have no way to access the rest of the pages or the menu (unless i'm doing it wrong). The way I solved this issue is by making the sidebar in a negative position. In the mobile browser I tested, it seems to disregard this, so you can still swipe to see the sidebar. But since you can not do this is a desktop browser, i implemented the links to access it (sort of reminiscent of WP's right arrow for apps access). Another benefit is that it allows the browser to natively direct user to a specific div using #. So if I sent someone a link to http://jssolichin.com/xwiki#attachments, it should load the webpage in that area (also why I used scrolling instead of tabs). What do you guys think? One thing that I am wondering though is, sometimes a few lines of extra code is needed to make sure all the feature work properly upon resize. Should I worry about this? Like if a viewer resizes the browser from a desktop to a mobile size, should I add extra lines to make sure he can view it correctly? A lot of this has to do with the resizing capability of the sidebar (which can't be accomplished with css). Next step: implement all the drop down and test compatibility on mobile (as I can get a hold of them) and firefox/safari/ie. Also, begin porting over to xwiki/simplifying/standardizing. Thanks friends! JS

[xwiki-devs] WYSIWYG goes to cache instead of opening the editor?

by echocoder

When editing an Xwiki page and choosing the WYSIWYG option instead of showing the editor it takes the user to a blank HTML cache page in /xwiki/resources/js/xwiki/xwe/*.cache.html. Do any of you know the cause of this and/or how to fix such? -- View this message in context: http://xwiki.475771.n2.nabble.com/WYSIWYG-goes-to-cache-instead-of-opening-… Sent from the XWiki- Dev mailing list archive at Nabble.com.

[xwiki-devs] [ANN] XWiki Summer 2012 Hackathon

by Vincent Massol

Hi devs and community at large, Every year XWiki SAS (http://xwiki.com) gathers all its employees for a Seminar and every year we have an internal hackathon. For example here are the results of last year: http://www.xwiki.com/xwiki/bin/view/Company/Hackathon2011 Previously the Hackathon was a 1 day event only. However this year we're changing the format; it'll run for 8 days! :) Thus we thought it could be a good idea to invite the XWiki Community to join us for a mega distributed Hackathon! So here's how I think we could organize it: * Start date: 20th of July. A mail will be posted on this day to announce the start * End date: 27th of July. A mail will be posted on this day to announce the end * Gathering results: from 28th to 6th of August. Everyone who participated should reply to the end of hackathon mail with what they did and post their stuff on http://extensions.xwiki.org or elsewhere * On around the 6th of August we'll have a blog post written on xwiki.org summarizing all that was done by everyone Those who have participated will also get XWiki T-Shirts. Anyone interested in joining the fun? Thanks -Vincent with my XWiki SAS employee hat

[xwiki-devs] Improved supported database testing and testing results

by Sorin Burjan

Hello, As you know, we have defined a supported database strategy, found here: http://dev.xwiki.org/xwiki/bin/view/Community/DatabaseSupportStrategy At the moment, in our release notes, we report the supported list of databases in the "Tested Databases" section. This is a little bit misleading, because we don't perform a full manual test on each of them. Also, at the moment, we don't have automated tests running on these databases. What I currently do is to test migration on each databases from an older version (in my case, I am using 2.7.2) to the current upcoming release. I usually perform these tests before RC1 so we make sure issues won't slip in the final release. Also, this testing is done on vanilla wiki's, so they don't reflect or simulate a large wiki migration with thousands of users and pages. What I want to propose is: 1) improve the "Tested Databases" section, so we list that we only test migrations and we don't perform a full test on each of the databases. This would mean adding a small explanation about this in the release notes pages. 2) When we release a new version, migrate myxwiki.org to the latest version, so users using it can report possible issues due to migration. This is a little hard for me to do since if something goes wrong, I could break a lot of things. Someone with more experience should do it, if there volunteers. I am waiting your feedback about this since I want to improve the visibility of testing, and also try to test migrations in a more real world environment Regards, Sorin B.
