How can I turn off the "shortcut" URLs where /bin/Space/Page is interpreted as /bin/view/Space/Page? (Specifically, I'm using mod_redirect to clean up the URL architecture and need to assume that anything prefixed /bin that isn't /bin/view needs to be passed through as an action.) - - - Hans Gerwitz http://phobia.com/

Big fix submission for problem with {rss} macro

by Trevor Cox

I've posted a fix for bug #XWIKI-283, and I hope someone can include it in the next release. When trying to show an RSS or RSS2 feed in a wiki page using the {rss} macro, you will see text like: "SyndContentImpl.value= ... {blog text} ... SyndContentImpl.type=text/plain" Here's the fix to java/com/xpn/xwiki/render/macro/rss/RSSMacro.java. It applies to xwiki 0.9.743 through subversion June 20, 2006. and to rome 0.6 through 0.8. 185c184 < .append(NEWLINE).append(entry.getDescription()) --- > .append(NEWLINE).append(entry.getDescription().getValue()) 218c217 < .append(NEWLINE).append(entry.getDescription()) --- > .append(NEWLINE).append(entry.getDescription().getValue()) Explanation: The following code appends the result of com.sun.syndication.feed.synd.SyndEntry.getDescription(). That would be fine if getDescription returned a String, but in fact it returns a feed.synd.SyndContent object. buf.append(NEWLINE).append("<div class='rssitemdescription'>") .append(NEWLINE).append(entry.getDescription()) .append(NEWLINE).append("</div>"); My test cases were: RSS: {rss:feed=http://gigazad.blogspot.com/rss.xml|count=4|full=true} RSS2: {rss:feed=http://www.mikegiesbrecht.com/Blog.php?feed_type=rss2|count=1|full=true} More details below. -- Trevor Cox skahasoftware.com Vancouver, Canada Ludovic Dubost wrote: > > Looks like I missed this one !!

Retrieve the content of the all versions using XML-RPC API...

by Fabrício Jailson Barth

Hi All, Someone knows how can I retrieve the content of the all the versions about one page in the wiki? At the moment, I did retrieve this: Page Main.Publicacoes Got versions: {modifier=XWiki.Admin, version=2, modified=Mon Jul 24 17:55:57 BRT 2006, id=Main.Publicacoes} {modifier=XWiki.Admin, version=3, modified=Mon Jul 24 17:57:39 BRT 2006, id=Main.Publicacoes} {modifier=XWiki.Admin, version=4, modified=Mon Jul 24 17:57:45 BRT 2006, id=Main.Publicacoes} {modifier=XWiki.Admin, version=5, modified=Mon Jul 24 17:57:53 BRT 2006, id=Main.Publicacoes} {modifier=XWiki.Admin, version=6, modified=Mon Jul 24 17:57:59 BRT 2006, id=Main.Publicacoes} {modifier=XWiki.Admin, version=7, modified=Mon Jul 24 17:58:06 BRT 2006, id=Main.Publicacoes} {modifier=XWiki.Admin, version=8, modified=Mon Jul 24 17:58:44 BRT 2006, id=Main.Publicacoes} {modifier=XWiki.Admin, version=9, modified=Mon Jul 24 17:59:03 BRT 2006, id=Main.Publicacoes} {modifier=XWiki.Admin, version=10, modified=Mon Jul 24 18:09:15 BRT 2006, id=Main.Publicacoes} {modifier=XWiki.Admin, version=11, modified=Mon Jul 24 18:14:26 BRT 2006, id=Main.Publicacoes} and the content of the last version. But, I couldn't find the method to access the content of all versions. Thank you ! Fabrício.

Re: [xwiki-users] Using XWiki in other databases than MySQL

by Ludovic Dubost

Yes, This is *very* useful. It's exactly what we need for databases we haven't tested XWiki on. So any field of more than 4096 should be converted to "text" in hibernate.cfg.xml (which should be compatible with mysql and the databases xwiki already works on). Oracle9Dialect should be use (does it mean forgeting support for Oracle8 ?) Text fields of more than 4096 cannot be handled using "like" so using the Lucene plugin is mandatory for Oracle Ludovic David Delbecq a écrit : > Reporting, out of my mind of months ago, for Oracle > > - First, oracle does assume an empty string same as null, this has 2 > majors implications > * The 'not null' String elements can get nulled when stored on > database, triggering lots of hibernate exception when they are retrieved > again.

Using XWiki in other databases than MySQL

by Ludovic Dubost

Hi, In order to possibly improve our database support in the future, I would be interested to discuss with any users that have ported XWiki to other databases than MySQL. We are especially interested by databases used by corporations like Oracle, Sybase, SQL Server. Would any of you that have ported/tried to port XWiki to another database tell us what has worked/not worked and what they have done. That would be great help. Since we now have the default database of XWiki as XML, we have the possibility to write a script to load this in any database. We just need to make sure that the core behavior of the storage engine is compatible with the target database. Thanks Ludovic -- Ludovic Dubost XPertNet: http://www.xpertnet.fr/ Blog: http://www.ludovic.org/blog/ XWiki: http://www.xwiki.com Skype: ldubost AIM: nvludo Yahoo: ludovic
