      Description

      As posted in the tapestry forums:

      At first I thought I could work around these issues but they seem to
      be popping up more and more throughout my application. Its really
      becoming an issue for me.

      Ever since I have moved from .page and .jwc files to annotations I get
      these exceptions more often.

      I don't believe I am doing anything wrong with these annotations. As
      you can see by the following one I have just declared a DelegateBean
      in my class. Using

      @Bean(SimpleValidationDeleage)
      public abstract SimpleValidationDelegate getDelegate();

      That same Delegate is used on mulitple pages and in components. From
      what I understand this should be acceptable.

      This issue also has sprung up on my declaring the same Persistent
      property on different pages or components using the @Persist
      annotation.

      I've also recieved a similar exception doing the following in which both the
      page and component contain:
      @InjectState("visit")
      public abstract void getVisitObj();

      I was able to work around the issue by changing the component to be
      @InjectState("visit")
      public abstract void getVisitObjComp();

      I didn't run into these problems before I used annotations. I'd also
      hate to have to go back to .page and .jwc files since there are so
      many files that I've changed.

      Here is an one of the exceptions:

      Exception invoking listener method searchLinkListener of component

          In my previous description I mentioned:
          "I've also recieved a similar exception doing the following in which both the
          page and component contain:
          @InjectState("visit")
          public abstract void getVisitObj();

          I was able to work around the issue by changing the component to be
          @InjectState("visit")
          public abstract void getVisitObjComp();
          "
          I meant "Visit" not "void"

          Which still causes this error to occur. What I end up having to do in order for this to work is completely remove the annotation and use something like:
          public Visit getPageVisit()

          { return ((MyPage)getPage()).getVisitObj(); }

          I am very surprised that this is not happening for others. I've been running into these issues constantly and currently is a big show stopper. I have pretty much decided to ditch annotations in components and just use .jwc again.

          Ok I am convinced that this bug only appears when you are using tapestry in caching=false mode. I was able to replicate the bug on a certain page everytime. When I allowed caching again and restarted my server the exception did not appear. So its not a show stopper just an annoyance.

          Kent Tong added a comment -

          Could this be what's happening:
          1) In the getComponentConstructor() method in ComponentConstructorFactoryImpl, the spec of the component which uses the Bean annotation is enhanced, ie, a bean spec is added to it. Note that the spec is a part of the global application namespace. The resulting component constructor is also added to the _cachedConstructors map.
          2) The reset service is called. This will tell the ComponentConstructorFactoryImpl to clear its _cachedConstructors map.
          3) When the getComponentConstructor() method is called again on that component again, as the spec is global, it already contains the bean spec. But as _cachedConstructors map is now empty, it will try to enhance the spec again, resulting a duplication bean spec and this exception.

          To solve the problem, one may add an "enhanced" flag in the component spec to avoid doing it twice.

          This is also hitting my team and its a big time killer, essentially making disable-caching=true useless when using annotations (at least in our app). disable-caching=true is very important for developer productivity and I'd love some hints as to how to fix it. I've done a bit of digging into the tapestry internals and I will follow up on Kent TOng's but this feels more like a race than a straight issue with bookkeeping on reset.

          I'd love to hear some comments from the Tapestry illuminati. Even pointers about how to go about tracking/fixing.

          I think Kent's analysis above is almost right on. I differ a bit because his analysis seems to indicate this would happen all the time for all components that have annotations when running with disable-caching=true. But because the specification's are ALSO cleared out when the reset occurs, in theory each request should see a fresh, unadorned, Spec, and never try to re-enhance a class with a spec that was already enhanced. I think there is a race that occurs when there are multiple requests in flight:

          1. Request A: arrives, and during processing a component spec is created for component Foo, cached, and used for request processing.
          2. Request B: arrives, and durign processing the same component spec for Foo is retrieved from cache, and used for request processing.
          3. Request A: The request finishes, calling resetEventDidOccur and clearing all caches.
          4. Request B: ComponentConstructorFactoryImpl.getComponentConstructor is called. The _cachedConstructor map is empty from step 3, so it tried to recreate the constructor, but does so using the spec which was fully adorned during the request processing for A.

          If this is true, then it only happens with multiple requests in flight simultaneously. THis is unlikely to hit a large set of apps in dev mode, but for apps with frames, iframes, or lots of simultaneous ajax going, it can happen easily (the latter is our case). The best solution in my mind is to run single threaded only in dev mode (when disable-caching=true). I am going to implement this as a servlet filter and see if the problem goes away. I will update this bug with a comment when I know more...

          I tried backporting your changes to 4.0.2.

          It seems to me that the only important change is in the PageSource class: The addition of the ESTIMATED_PAGES constant, the _keyMap field, the added getPageLock() method, and the lock aquisition code added to the getPage() method. Anyway, after performing these changes in T4.0.2 and rebuilding and updating my jars, I still get the same errors as before, e.g. the bug is either not fixed, or my backport doesn't work. I'll include my patch in an attachhed file.

          Would it be possible to get an official backport of this bugfix to 4.0.x? I really need it.

          Hi Jan,

          Maybe. If you can find a way for me to definitively re-produce this I'll backport it to 4.0.3 for you

          I just can't get it to happen. A test case or "something" that shows me this would be a great help.

          It's problematic to give a test case because "the boss" let me show you too much of our code. Instead, I've been digging into the problem and I have ended up in the ComponentConstructorFactoryImpl.getComponentConstructor() method. The important line is:

          ComponentConstructor result = (ComponentConstructor) _cachedConstructors.get(specification);

          and when this one returns null, enhancement is performed. Two enhancements on the same component class results in the error, that's the root of my problem.

          Now how can the component class be enhanced twice? It's possible if _cachedConstructors.get(specification) returns null at least twice for the same component. Therefore, just before the line, I output the hashcode of the specification parameter, and it shows the fact that multiple IComponentSpecification instances for the same component exist, e.g. rendering my page (which contains IFrames which result in multiple pages being rendered simultaneously) gives the following output for the Insert component.

          org.apache.tapestry.components.Insert 18891813
          org.apache.tapestry.components.Insert 21977649
          org.apache.tapestry.components.Insert 24229066
          org.apache.tapestry.components.Insert 26810747
          org.apache.tapestry.components.Insert 613258
          org.apache.tapestry.components.Insert 8310913

          As long as the component doesn't have annotations, there is no problem. But my components are also loaded multiple times, e.g.

          dk.mydomain.projects.tapestry.components.ExternalPageIframe 13472381
          dk.mydomain.projects.tapestry.components.ExternalPageIframe 29460424

          The dk.mydomain.projects.tapestry.components.ExternalPageIframe has annotations and the method

          _chain.performEnhancement(eo, specification);

          therefore fails misably because the ExternalPageIframe class is enhanced twice.

          The question that needs to be answered now is: Why are there multiple instances of IComponentSpecification for the same components, even for the built-in components? The example above shows that there are 6 IComponentSpecification for the org.apache.tapestry.components.Insert component.

          Ok, the answer to the question I asked above is, because disable-caching is set to true. This results in resetEventDidOccur() being called on ComponentConstructorFactoryImpl, clearing _cachedConstructors, supposedly after the page has rendered.

          Normally this doesn't appear to be a problem because I'm able to reload a simple page in my browser without causing the error.

          But it's obviously a big problem when the cache is cleared while other pages are rendering when they need the components that the first page included (and afterwards cleared from the cache). Remember, I have a lot of Iframes on my page.

          I suspect it may have to do with the fact the the reset event is fired through an iteration in org.apache.tapestry.services.impl.ResetEventHubImpl.fireResetEvent().

          Both org.apache.tapestry.services.impl.SpecificationSourceImpl and org.apache.tapestry.services.impl.ComponentConstructorFactoryImpl receive the event, one after the other. Could this result in a race condition where one has cleared its cache and the other hasn't yet, and then another page does something in between?

          Sorry, but your testcase doesn't fail on my machine, it gives me two counters in two windows - the second one with a ten second start delay.

          WinXP + JDK 1.5.0_09 + Tomcat 5.5.20 + T4.0.2

          Thanks Vitaliy, your example app made this really easy to track down.

          The patch.txt file attached above doesn't fix the bug. I back-ported the working fix from the 4.1.1 branch back to 4.0.2 - only 2 files are required:

          • framework\src\java\org\apache\tapestry\services\impl\ComponentConstructorFactoryImpl.java
          • framework\src\java\org\apache\tapestry\services\impl\DisableCachingFilter.java

          Note that the above two files are using the JDK 1.5 java.util.concurrent.locks.ReentrantLock class, so if you're compiling in 1.4, you'll need to replace it with the backport-concurrent version of ReentrantLock.
