[xwiki-devs] Velocity parsed template caching

by Łukasz Skowroński

Hi, I've done some XWiki profiling and it seems that the biggest bottlenecks are Velocity template evaluating (in XWikiVelocityRenderer) and Lucene Index Updater thread... Did you think about using StringResourceLoader (or something similar) instead of Velocity.evaluate()? I believe caching parsed ASTs rather than reparsing the same strings everytime could significantly improve overall performance. Here you can find some interesting discussion about StringResourceLoader --> http://www.mail-archive.com/user@velocity.apache.org/msg02135.html Well, I'd like to give it a try. Do you know any traps/gotchas I should be aware of? Kind regards Lukasz

[xwiki-devs] [VOTE] Add Document.rename(String newDocumentName, List<String> backlinkDocumentNames, List<String> childDocumentNames) API

by Vincent Massol

Hi, I'm applying Caleb's path for http://jira.xwiki.org/jira/browse/XWIKI-1082 ("When renaming a page, also update the "parent" field of subpages"). We need a new signature for rename so that the rename UI can let the user decide which document having the document being renamed as parent needs to be updated. Document.rename(String newDocumentName, List<String> backlinkDocumentNames, List<String> childDocumentNames) Here's my +1 Thanks -Vincent

[xwiki-devs] Feed Plugin: Simplify the Feed Plugin Api Interface

by Andreas Schaefer

Hi Based on this JIRA report: http://jira.xwiki.org/jira/browse/XWIKI-4430 it would be necessary to create a new set of methods just to be able to pass an additional parameter to the calls. Because this makes it harder and harder to deal with Plugin I would suggest to use a Parameter Container which could contain: - Feed Type (Blog, Web, etc) - Type (Query, List or Feed ) - List or - Query, Count and Start or - Feed - Metadata - Object Class Name - Output Type (RSS, Atom etc) Then we would only need 2 major methods: - SyncdFeed getFeed( FeedParams ) - String getFeedOutput( FeedParams ) This is what I came up so far (without the Feed Type): /** * @see #getBlogFeed(String, int, int, Map) * @see #getFeedOutput(SyndFeed, String) */ public String getBlogFeedOutput( FeedParams params) { SyndFeed feed = getBlogFeed( params ); String ret = getFeedOutput( feed, params.getOutputType() ); return ret; } public SyndFeed getBlogFeed( FeedParams params) { Map<String, Object> myMetaData = Collections.emptyMap(); if( params.getMetaData() != null ) { myMetaData = params.getMetaData(); } Map<String, Object> blogMappings = null; if( params.getObjectClassName() == null ) { blogMappings = BLOG_FIELDS_MAPPING; } else { blogMappings = new HashMap<String, Object>(); blogMappings.put(SyndEntryDocumentSource.FIELD_TITLE, params.getObjectClassName() + "_title"); blogMappings.put (SyndEntryDocumentSource.FIELD_DESCRIPTION, params.getObjectClassName () + "_content"); blogMappings.put (SyndEntryDocumentSource.FIELD_CATEGORIES, params.getObjectClassName() + "_category"); blogMappings.put(SyndEntryDocumentSource.CONTENT_LENGTH, new Integer(400)); } SyndFeed blogFeed = null; if( params.getType() == FeedParams.Type.QUERY ) { String query = params.getQuery(); if (query == null) { XWikiRequest request = getXWikiContext().getRequest(); String category = request.getParameter("category"); if (category == null || category.equals("")) { query = ", BaseObject as obj where obj.name=doc.fullName and obj.className='" + BLOG_POST_CLASS_NAME + "' and obj.name<>'" + BLOG_POST_TEMPLATE_NAME + "' order by doc.creationDate desc"; } else { query = ", BaseObject as obj, DBStringListProperty as prop join prop.list list where obj.name=doc.fullName and obj.className='" + BLOG_POST_CLASS_NAME + "' and obj.name<>'" + BLOG_POST_TEMPLATE_NAME + "' and obj.id=prop.id.id and prop.id.name='category' and list = '" + category + "' order by doc.creationDate desc"; } } blogFeed = getFeed( query, params.getCount(), params.getStart(), getSyndEntrySource(SyndEntryDocumentSource.class.getName(), blogMappings), Collections.EMPTY_MAP, fillBlogFeedMetadata(myMetaData) ); } else { blogFeed = getFeed( params.getEntries(), getSyndEntrySource (SyndEntryDocumentSource.class.getName(), blogMappings), Collections.EMPTY_MAP, fillBlogFeedMetadata(myMetaData) // params.getEntries(), getSyndEntrySource (SyndEntryDocumentSource.class.getName(), blogMappings), myMetaData, fillBlogFeedMetadata(myMetaData) ); } if (blogFeed != null) { blogFeed.setImage(getDefaultFeedImage()); } return blogFeed; } public static class FeedParams { public enum Type { QUERY, LIST } private static final String DEFAULT_OUTPUT_TYPE = "rss_2.0"; private static final int DEFAULT_COUNT = 10; private static final int DEFAULT_START = 0; private Type type; private List<Object> entries; private String query; private int count = DEFAULT_COUNT; private int start = DEFAULT_START; private Map<String, Object> metaData; private String outputType = DEFAULT_OUTPUT_TYPE; private String objectClassName; public FeedParams( List<Object> entries, String objectClassName, Map<String, Object> metaData, String outputType ) { this.type = Type.LIST; this.entries = entries; this.metaData = metaData; this.outputType = outputType == null ? DEFAULT_OUTPUT_TYPE : outputType; this.objectClassName = objectClassName; } public FeedParams( String query, Integer count, Integer start, String objectClassName, Map<String, Object> metaData, String outputType ) { this.type = Type.QUERY; this.count = count == null ? DEFAULT_COUNT : count; this.start = start == null ? DEFAULT_START: start; this.metaData = metaData; this.outputType = outputType == null ? DEFAULT_OUTPUT_TYPE : outputType; this.objectClassName = objectClassName; } public Type getType() { return type; } public String getQuery() { return query; } public int getCount() { return count; } public int getStart() { return start; } public List<Object> getEntries() { return entries; } public Map<String, Object> getMetaData() { return metaData; } public String getOutputType() { return outputType; } public String getObjectClassName() { return objectClassName; } } What do you think? -Andy

[xwiki-devs] Loading a Groovy Script from another Script

by Andreas Schaefer

When I try to load a Groovy script using xwiki.parseGroovyFromPage() then I fail when this Script is enclosed inside '{{groovy}}'. This means I have to use two different documents when I want to use the same document to be loaded by XWiki and by xwiki.parseGroovyFromPage() because one needs the be enclosed by '{{groovy}} and the other can't. Isn't there a way to remove '{{groovy}}' when parsed so that the scripts can be used for both? In addition the 'GroovyScriptEngineImpl' which is used for the Binding does throw a NoSuchPropertyException when a property is not available. This makes it cumbersome to test for properties and add them if not already put inside. For example I need some objects over and over like 'BlogParams' and so I would like to store them inside the bindings. In order to avoid the exception I either have to catch the Exception (time consuming) or I need to get the properties map and check if the property is already added to the map. Is there a better way to do that? Cheers - Andy

[xwiki-devs] XWiki developer conference

by Sergiu Dumitriu

Hello friends of XWiki, Several XWiki members will be participating at FOSDEM next year in February ( http://fosdem.org/ ), and we're trying to determine if there's interest in applying for a devroom, which would mean half a day or more of XWiki-related presentations. - Are there any people interested in participating to such presentations? - Does anybody want to do such a presentation, besides XWiki committers? I'd need answers to these questions soon, since the deadline for application is in two days. Note that FOSDEM is a developer-oriented conference, so presentations should be rather technical. FYI, there is no participation fee, anybody can attend FOSDEM as long as there are places in the rooms. -- Sergiu Dumitriu http://purl.org/net/sergiu/

[xwiki-devs] Enabling/disabling monitoring

by Łukasz Skowroński

[XWiki Enterprise 2.0.3 on Windows XP] Hi, XWiki Enterprise\webapps\xwiki\WEB-INF\xwiki.cfg file contains the following lines: #-# Enable light monitoring of the wiki performance. Records various statistics, like number of requests processed, #-# time spent in rendering or in the database, medium time for a request, etc. Disable for a minor increase of #-# performance and a bit of memory. # xwiki.monitor=1 This is quite misleading because although xwiki.monitor=1 is commented out XWiki still monitor requests. To actully turn it off one has to put xwiki.monitor=0 I would vote to turn off monitoring if xwiki.monitor setting is not defined (i.e. is commented out). Kind regards Lukasz
