This means that we acknowledge that we don't need them since we're making evolutive changes (without major breakages or breakages are done evolutively too with deprecation cycles, etc). This would mean a new numbering scheme that doesn't have a major value.

[xwiki-devs] [proposal] New module to handle large binary objects in a generic way.

by Caleb James DeLisle

In light of the need for better attachment handling, I spent the past few days working on the basic framework for a new module to support large objects. The code can be viewed here: http://svn.xwiki.org/svnroot/xwiki/contrib/sandbox/xwiki-blob/src/main/java… Use case #1: Multiple methods of storing content and the ability to define more. Use case #2: Thread safe locking to prevent concurrent modifications from damaging content. Use case #3: ACID commit/rollback protection. The API user has 2 access points. BinaryObject is a thread safe interface with ACID and option of using OutputStream or InputStream to set and get data. StorageItem is a simplistic interface modeled after a small subset of the methods in java.io.File. If you create a component which implements StorageItem, BinaryObjectProvider will allow you to access a BinaryObject which uses your StorageItem for persistent storage. Example: @Requirement private BinaryObjectProvider provider; private BinaryObject binaryObj; public void initialize() { this.binaryObj = this.provider.get("myImpl"); } "myImpl" is the hint for the StorageItem which you may define. The next step is of course to add versioning support but I think this will provide a solid foundation to build that on. WDYT? Caleb

[xwiki-devs] rendering breadcrumbs

by [Ricardo Rodriguez] eBioTIC.

Hi, Following this thread http://markmail.org/thread/jbd62pddnuqvm5ku and after trying the same example in the new XE 2.6-SNAPSHOT.32286, I see that variables set in the body of the document keep being well rendered/printed in the title of the document but not in the breadcrumbs. I would like to know if there is some design reason for printing breadcrumbs before the content of the document or we could expect that in some future version this could be possible. Thanks!

(at least this is the strategy I've always followed since a stack trace takes up a lot of space, draws the eye, etc). What I do usually is just display the nested message without the stack trace. Note: It might be good to have a utility method somewhere to extract all messages from all nested exceptions without the stack trace. WDYT? Thanks -Vincent [snip]

[xwiki-devs] Document information panel - parent

by Paulo Zenida

Hello devs, I installed the latest stable version of XWiki (2.5) and I found out that the document information panel does not include a parent field. Therefore, I tried to include that field, as in the older version I had (2.4.3) but saving the document does not save the parent in the database. Is this a bug or was there a change in the way we say what is the parent page of a given document? I tried to search for known issues in Jira but had no success on this one. Best, Paulo Zenida

[xwiki-devs] [Proposal]JavaScript console.log wrapper for our convenience

by Jerome Velociter

Hi devs, I'd like to commit a console.log wrapper in xwiki.js that does some checking before logging, in the spirit of http://paulirish.com/2009/log-a-lightweight-wrapper-for-consolelog/ Something like : var XWiki = { //snip /** * console#log wrapper for your developer own convenience */ log: function(){ if(typeof console != "undefined"){ console.log( Array.prototype.slice.call(arguments) ); } }, // snip } WDYT ?

[xwiki-devs] [Proposal] Adopt the JavaScript module pattern

by Jerome Velociter

Hi devs, I'd like to propose we adopt the module pattern for our XWiki's javascript modules. The pattern and its variations is well described here : http://www.adequatelygood.com/2010/3/JavaScript-Module-Pattern-In-Depth I would follow the author advice and go for loose augmentation and sub-modules. I don't think we need private states. Main avantages I see over what we currently are doing are : * It enforces namespacing and the use of a private scope versus manual namespacing in the global window scope * It easily supports global imports (can be useful for example when using jQuery in addition to prototype) * It's more elegant and easier to read. For example : var XWiki = (function(XWiki, $j){ var mySubModule = XWiki.mySubModule = XWiki.mySubModule || {}; // my sub module code here return XWiki; })(XWiki, jQuery) instead of the tedious : if (typeof XWiki == "undefined") { XWiki = new Object(); } if (typeof XWiki.mySubModule == "undefined") { XWiki.mySubModule = new Object(); } // my sub module code here I'm +1 to adopt it. WDYT ? Jerome

[xwiki-devs] [VOTE] XE 2.6 Roadmap

by Vincent Massol

Hi, I'd like to propose that we have a short XE 2.6 release. The rationale is that we've been developing lots of new features in the past releases and I think it's time to stabilize what we have. By stabilize I mean: - fix bugs - homogenize UI - clean up stuff (refactoring, etc) In addition we have 2 features we had planned for 2.5 which have slipped and we could finish them in 2.6 too (Sergiu said he was almost done with the "Email this page" feature and didn't have the time to slip it in the 2.5): - Email this page: Sergiu - Recent Activity (refactoring of Recent Changes based on the Activity Stream): Raluca + Caty + JV to apply the patch The idea would be to have the following dates: - 2.6RC1: 1st of November 2010 (there's no M1) - 2.6 final: 18h of November If we agree, is there anyone who'd like to be the release manager for this release? If nobody volunteers I can do it. If we agree, I'll send another mail afterwards with some ideas for XE 2.7 and a potential XE 3.0 release. Note that XE 2.6 would be a first step in stabilizing XE for an upcoming 3.0 release :) But even without this vision doing a short stabilization release from time to time is always a good think I believe. It's also not too long so that people don't need to hold new stuff for too long. Here's my +1 Thanks -Vincent

[xwiki-devs] [Proposal] Transformation activation

by Vincent Massol

Hi, Requirement ========== UC1: ability to package transformations in the platform that are not enabled by default (for ex WikiWordTransformation) UC2: ability in the future to install a new transformation using the extension manager and make it active without restarting xwiki (and without complex operations to activate it) UC3: ability to have a list of transformations active in a given part of the xwiki code and another list in another part of the code Proposal ======= * Introduce a XWikiTransformationManager implementation (hint = "xwiki"), located in xwiki-core/ * Make it use CoreConfiguration and introduce core.viewTransformations configuration properties (in some future we'll have a separate module to perform page rendering - The rendering module is about rendering content not pages). Ex: core.transformations = macro, icon (values are role hints) * Default property value would be: macro, icon * DefaultTransformationManager will continue to exist and be part of the rendering module (and runs all transformation it can find). We could decide to remove it at some point if we don't see any value although it could stay as an example implementation in the rendering module (which can be used standalone). This proposal solves UC1 and UC3. It's less clear how it can solve UC2. When the extension manager is available we could simply remove this configuration property and simply "deactivate" a given transformation, thus making it inactive. I believe this will be the best practice in the future for activating/deactivating (set of) components. There could be 2 ways: making it not part of the classloader and/or telling the component manager to unregister/register a component. Thus I believe this proposal is good enough for now. WDYT? Thanks -Vincent
