[xwiki-devs] [GSOC][WEBDAV] Problem With Core Failing (XWikiCacheStore)
Hi All, I cannot test xwiki-webdav anymore because XWikiCacheStore throws a null pointer exception that i cannot figure out. I think this is introduced by a recent commit, please help me with this.

Yes this bug was introduced by Thomas' recent commit I guess. Thomas should be able to answer you tomorrow morning (GMT+1). Thomas, btw did you check if all XWiki entry points continue to work and especially XMLRPC and GWT? Thanks -Vincent On Jun 18, 2008, at 9:11 PM, Asiri Rathnayake wrote:

Hi, This error append when you try to use cache component before ComponentManager initialization, it's not really related to cache itself. How do you reproduce this ? Is it in a unit test ? I don't have any problem in virtual or non virtual mode when using xwiki in standalone or from Eclipse.... On Wed, Jun 18, 2008 at 9:11 PM, Asiri Rathnayake <[email protected]> wrote:

Hi Thomas, Sorry for the late reply, i just woke up :) This is ludovic's original code, <code> context = Utils.prepareContext("", request, response, engine); context.setMode(XWikiContext.MODE_GWT); context.setDatabase("xwiki"); XWiki xwiki = XWiki.getXWiki(context); </code> So yes, Utils.prepareContext() is used but XWiki.getXWiki() fails.

So yes, Utils.prepareContext() is used but XWiki.getXWiki() fails.
I just committed a throw in Utils.getComponent when component manager has not been initialized, that way we will be sure it's the problem or not.

Hi,
This error append when you try to use cache component before ComponentManager initialization, it's not really related to cache itself.
How do you reproduce this ? Is it in a unit test ? I don't have any problem in virtual or non virtual mode when using xwiki in standalone or from Eclipse....

Hi Thomas,
Sorry for the late reply, i just woke up :)
This is ludovic's original code,
<code> context = Utils.prepareContext("", request, response, engine); context.setMode(XWikiContext.MODE_GWT); context.setDatabase("xwiki"); XWiki xwiki = XWiki.getXWiki(context); </code>
So yes, Utils.prepareContext() is used but XWiki.getXWiki() fails.
I just committed a throw in Utils.getComponent when component manager has not been initialized, that way we will be sure it's the problem or not.
Thanks, I will check this asap and post a mail. - Asiri

Previously we used a small workaround for a problem we encountered with component manager as follows,
In Utils.prepareContext() method we had a problem where the component manager is null ... so we did,
ComponentManager componentManager = (ComponentManager) engine_context.getAttribute(ComponentManager.class.getName());
+ if(null != componentManager) { + context.put(ComponentManager.class.getName(), componentManager); + }
You also have to call static Utils.setComponentManager(componentManager) to init Utils ComponentManager. Utils.getComponent("component") does not use the context's ComponentManager anymore to be able to get component whithout context.
This worked fine untill recently. But I think now we have to handle this issue. The main problem is,
ComponentManager componentManager = (ComponentManager) engine_context.getAttribute(ComponentManager.class.getName());
Here, componentManager becomes null. What could be the reason for this ?
Thanks a lot.

<dump> java.lang.NullPointerException at com.xpn.xwiki.store.XWikiCacheStore.initCache(XWikiCacheStore.java:95) at com.xpn.xwiki.store.XWikiCacheStore.initCache(XWikiCacheStore.java:80) at com.xpn.xwiki.store.XWikiCacheStore.<init>(XWikiCacheStore.java:62) at com.xpn.xwiki.XWiki.initXWiki(XWiki.java:675) at com.xpn.xwiki.XWiki.<init>(XWiki.java:652) at com.xpn.xwiki.XWiki.getMainXWiki(XWiki.java:312) at com.xpn.xwiki.XWiki.getXWiki(XWiki.java:383) at

In XWikiCacheStore.initCache() method,
CacheFactory cacheFactory = context.getWiki().getCacheFactory();
here, cacheFactory has become null.
I've only found this problem and currently looking into it, if anyone can help me get over this quickly it would be a big help.
Thanks.

ComponentManager componentManager = (ComponentManager) engine_context.getAttribute(ComponentManager.class.getName());

Hi,
This error append when you try to use cache component before ComponentManager initialization, it's not really related to cache itself.
How do you reproduce this ? Is it in a unit test ? I don't have any problem in virtual or non virtual mode when using xwiki in
standalone
or from Eclipse....

Thanks, I will look into this.
I can do it directly in xwiki-webdav and commit in sandbox if you want.
That's great! Then i can start looking into webdav work straight away. Anyway, I will have go through your code and understand it because learning about xwiki-core is part of gsoc. Also, if we can fix this, i think we can get rid of the additional patch (to core) required to test xwiki-webdav. Thanks a lot. - Asiri

I tried to follow this scheme but now I'm getting a different problem, <dump> java.lang.ClassCastException: org.apache.maven.plugin.MavenPluginDiscoverer at org.codehaus.plexus.component.discovery.DefaultComponentDiscovererManager.initialize(DefaultComponentDiscovererManager.java:94) at org.codehaus.plexus.container.initialization.InitializeComponentDiscovererManagerPhase.initializeCoreComponent(InitializeComponentDiscovererManagerPhase.java:36) at org.codehaus.plexus.container.initialization.AbstractCoreComponentInitializationPhase.execute(AbstractCoreComponentInitializationPhase.java:37) at org.codehaus.plexus.DefaultPlexusContainer.initializePhases(DefaultPlexusContainer.java:914) at org.codehaus.plexus.DefaultPlexusContainer.initialize(DefaultPlexusContainer.java:858) at org.codehaus.plexus.DefaultPlexusContainer.construct(DefaultPlexusContainer.java:834) at org.codehaus.plexus.DefaultPlexusContainer.<init>(DefaultPlexusContainer.java:204) at com.xpn.xwiki.plugin.webdav.XWikiDavResourceImpl.getComponentManager(XWikiDavResourceImpl.java:1441) at com.xpn.xwiki.plugin.webdav.XWikiDavResourceImpl.getXWikiContext(XWikiDavResourceImpl.java:348) at com.xpn.xwiki.plugin.webdav.XWikiDavResourceImpl.<init>(XWikiDavResourceImpl.java:213) at com.xpn.xwiki.plugin.webdav.XWikiResourceFactoryImpl.createResource(XWikiResourceFactoryImpl.java:105) at com.xpn.xwiki.plugin.webdav.XWikiResourceFactoryImpl.createResource(XWikiResourceFactoryImpl.java:69) at com.xpn.xwiki.plugin.webdav.XWikiDavServlet.service(XWikiDavServlet.java:351) at javax.servlet.http.HttpServlet.service(HttpServlet.java:820) at org.mortbay.jetty.servlet.ServletHolder.handle(ServletHolder.java:487) at org.mortbay.jetty.servlet.ServletHandler.handle(ServletHandler.java:363) at org.mortbay.jetty.security.SecurityHandler.handle(SecurityHandler.java:219) at org.mortbay.jetty.servlet.SessionHandler.handle(SessionHandler.java:181) at org.mortbay.jetty.handler.ContextHandler.handle(ContextHandler.java:738) at org.mortbay.jetty.webapp.WebAppContext.handle(WebAppContext.java:405) at org.mortbay.jetty.handler.ContextHandlerCollection.handle(ContextHandlerCollection.java:206) at org.mortbay.jetty.handler.HandlerCollection.handle(HandlerCollection.java:113) at org.mortbay.jetty.handler.HandlerWrapper.handle(HandlerWrapper.java:152) at org.mortbay.jetty.Server.handle(Server.java:325) at org.mortbay.jetty.HttpConnection.handleRequest(HttpConnection.java:535) at org.mortbay.jetty.HttpConnection$RequestHandler.content(HttpConnection.java:873) at org.mortbay.jetty.HttpParser.parseNext(HttpParser.java:648) at org.mortbay.jetty.HttpParser.parseAvailable(HttpParser.java:211) at org.mortbay.jetty.HttpConnection.handle(HttpConnection.java:391) at org.mortbay.io.nio.SelectChannelEndPoint.run(SelectChannelEndPoint.java:410) at org.mortbay.thread.QueuedThreadPool$PoolThread.run(QueuedThreadPool.java:488) </dump> Then after little browsing i came across http://jira.codehaus.org/browse/PLX-331 and then tried, 1. Build plexus-servlet locally. 2. Build xwiki-plexus locally (with the new version of plexus-servlet) 3. Build & tried `mvn jetty:run` on xwiki-webdav But still it gives the same error. I am so stuck here and need your help to fix this. Simply, i need to know how to properly initialize the componentManager. The procedure used in (/trunks/xwiki-platform-tools/xwiki-shared-tests/src/main/java/com/xpn/xwiki/test/AbstractXWikiComponentTestCase#getComponentManager()) doesn't seem to work for me. Please help. - Asiri
Thanks a lot.

PS : Previously vincent said not to use this workaround but we used it
since
it worked.

ok, I think the problem is that when the first connection is webdav ComponentManager is not initialized in Utils
