[xwiki-devs] [VOTE] New model script service APIs

by Jerome Velociter

Hello, For my work on the pretty thumbnails I also had the need to add some service API to the Model module script service. Basically the same kind of APIs that did already exist to resolve documents and attachments from a string representation, but this time to resolve object references and object properties references. Here they are : public ObjectReference resolveObject(String stringRepresentation) public ObjectReference resolveObject(String stringRepresentation, String hint, Object... parameters) public ObjectPropertyReference resolveObjectProperty(String stringRepresentation) public ObjectPropertyReference resolveObjectProperty(String stringRepresentation, String hint, Object... parameters) WDYT ? My +1 -- Jerome Velociter Winesquare http://www.winesquare.net/

[xwiki-devs] About the merits of private static functions.

by Caleb James DeLisle

I have found that I like static private functions because they allow me to make promises about my code, making it more self explanatory and I was interested in opinions from others about it. It's not something I would want to force on other people but I would use it myself if people don't think it's too messy. Reasoning: A private method which does not touch any state of the is easy to review, it has no side channels to modify or access information so: #1 with the same inputs it will always give the same output. #2 it will not affect the world around it aside from it's inputs and output (no surprise side effects). By declaring the private method static, you make that promise and the compiler will hold you to it. As a reviewer I can let my guard down when looking at the code because it doesn't affect object state so it can't be the source of some types of bugs. The code is sandboxed so to speak. These assumptions do not hold true if static variables are used but I believe those should never be used unless absolutely necessary and when they are, code should be reviewed more closely anyway. Example: https://github.com/xwiki/xwiki-rendering/blob/master/xwiki-rendering-transf… If I were writing this now, I would be tempted to make these into static functions: private Block convertToDeepTree(Block sourceTree, String iconName) private void mergeTree(Block targetTree, Block sourceTree) private int indexOf(List<Block> targetBlocks, Block block) private boolean blockEquals(Block target, Block source) Anyone have any thoughts on this pattern?

[xwiki-devs] [VOTE] Remove unnecessary javadoc for overriding methods

by Vincent Massol

Hi devs, I've just realized that using @override is enough to generate a proper javadoc copied from the overriden method and that checkstyle doesn't complain either. Basically instead of writing: /** * {@inheritDoc} * * @see org.xwiki.logging.LoggerManager#popLogListener() */ @Override public EventListener popLogListener() We can simply write: @Override public EventListener popLogListener() Advantages: 1) Less text to type and smaller class files 2) Less duplicated text I thus propose to use this from now and to progressively remove unnecessary javadoc in our legacy code. BTW this is also explained in the javadoc tool: See section "Automatic Reuse of Method Comments" in http://download.oracle.com/javase/1.3/docs/tooldocs/win32/javadoc.html WDYT? Here's my +1 Thanks -Vincent

[xwiki-devs] [Proposal] New JIRA module in platform

by Vincent Massol

Guys, I should have sent this mail before pushing my changes but here it's just after the fact… Basically I've replaced xwiki-platform-swizzle with xwiki-platform-jira The details are on http://jira.xwiki.org/jira/browse/XWIKI-6879 I hope it's fine. My next step is to make it work with the extension manager (thomas M is on it) and to document it on extensions.xwiki.org. Thanks -Vincent

[xwiki-devs] [proposal] Introduce a pointer class.

by Caleb James DeLisle

In order to fix a problem with the cache, I would like to add a pointer type to the storage api. The problem with the cache is there are multiple names which, when asked of the persistent store, return the same document. There is no effective way to know what all names which will return that document. When a document is modified, it is removed from the cache but the only version removed is it's "real" name. All of the other names for it linger in the cache eating up memory and threatening to provide someone stale data. Instead of caching the document, we could cache a pointer to the document and when it became stale, the pointer could be set to null and then any other name under which that document was cached would look up a null pointer and the cache logic could remove it. I would like to add it to xwiki-platform-store-api module and it will look roughly like this: package org.xwiki.store; public final class Pointer<T> { /** The thing which this pointer points to. */ public T target; } WDYT?

[xwiki-devs] How to get multiple values from object property.

by Karel Gardas

Hello, I have a XWiki object of a class where one property is defined as a list. During the page creation of this object (by using appropriate template provider) I'm setting several values from the list of possible values for the property. My problem is that although I've set several values I still get just one value when I look at the object properties in appropriate sheet class. E.g. I do have BookClass which besides other props defines property `kind' where kind might have `fantasy', `drama', or `novel' value. It also might have several values -- well, not good example but I hope this illustrates what I'm doing here. And now when I create new page as a book I set several kinds (for example fantasy & drama) then when I see the page I see only fantasy as the book kind. I'm using XWiki 3.1 snapshot as of May 27 2011. My question is it a known bug, am I doing anything wrong or was it already fixed (in case of bug)? Thanks a lot! Karel

[xwiki-devs] about login and logout using XWiki REST API

by Jun Han

Dear all, I am on the way of replacing the xmlrpc implementation of RemoteXWikiDataStorage implements IDataStorage {}. One question is about how to implement login and logout functionality via REST API. From REST API document, users can be authenticated via something like: 1. XWiki session 2. HTTP Basic Auth. HTTP basic auth can be implemented via adding HTTP header to the HTTP request, then XEclipse can display Xwiki Resources by parsing the response. Therefore, do we need to implement login and logout methods? Best regards Jun Han

Report the added files and the modified files c. Installation instructions 3. Testing it in Firefox, chrome, safari and ie6, ie7, ie8. Currently: a. Firefox works fine in both linux and windows. Not test in IOS b. Suggestion box can not be shown in the right place in chrome, I have found the problem, and I am fixing it now. c. Safari works fine in windows. not test in linux and IOS. d. Haven't test in ie6, ie7 and ie8 In next week, I will do the following things； 1. Continue testing it in a. Safari in Linux. b. fix the bug found for chrome c. test it in ie6, ie7 and ie8. 2. Write jasmine tests for link autosuggestions. -- 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
