My solution was to resurrect the floating console and have an option that lets the floating console be present along with the browser's real JavaScript console. This allows all the console messages to be captured in the screen and content capture at the end of a failed test. See my twitter feed (@hlship) for some screen shots.

Re: Tapestry performance
Finally they have added test that actually tests web frameworks - Fortunes test but no Tapestry yet. Does anyone is going to contribute the fortune test? Performance can be black magic. On the one hand, I've heard some specific things about Node.js performance that are very positive. Certainly, when developing for Node, the virtually instance server startup is wonderful.

Java has beaten us down into thinking that code needs lots of time to start up. However, Node.js is constantly switching contexts in significant ways. All those callbacks executing in, effectively, a chaotic order means that memory must be swept into and out of core quite constantly. In a Java-style synchronous server, the operating system has more clues about what memory should stay resident based on which threads have been recently active. Operating systems are very good at managing virtual memory, when you let them! It's probably impossible to compare things in an apples-to-apples way, however. I appreciate that single-thread simplicity of Node ... no locks, no deadlocks, no concerns about memory visibility between threads, no synchronize, no ConcurrentReadWriteLock, huzzah! The flip side is that in node you have to always be on your toes w.r.t. to writing everything in the callback style. That's not everyone's cup of tea ... and in some cases, can be truly complicated to manage, especially figuring out how to respond to errors when you are in the middle of an indeterminate number of partially executed work flows.

With synchronous server, there is no poll(), just the read and write, thus the overhead of the poll() and its setup is eliminated. Now it all comes down to the OS threading and I/O performance, and the real surprise was that the multiple threads, even 100s of thousands of them, all doing IO were not bogging down the system at all.

I'm already somewhat unhappy at the complexity of the code; I'd prefer not
to make it any more complicated. I think race conditions on the write lock
are going to be pretty rare and probably only occur on a somewhat saturated

In addition, in a ReentrantReadWriteLock, the write lock appears to return
false if any thread has the read lock, which could result in
the initialization code never being run.

There are many things in Tapestry that don't fit this model.
Sometimes the value being lazily created is so expensive, it would be
invalid to allow multiple threads to create it. In other cases, more
than one shared field is updated.
Hm, but the second check inside 'synchronized' block is supposed to avoid
creating value on multiple threads. For example:
private volatile Messages messages;
public Messages getMessages()
{
if (messages != null)
{
return messages;
}
synchronized (this) {
if (messages != null)
{
return messages;
}
messages = elementResources.getMessages(componentModel);
// --- only called if no other thread did this before
}
return messages;
}
After review, in this one specific case, I've removed the concurrency
code; the change to the messages field is individual and atomic, and
the value from the elementResources.getMessages() method is cached by
the eventual service implementation.

Re: Tapestry Transactions
OpenSessionInViewFilter has nothing to do with detached entities, it only keeps session open till view is rendered otherwise lazy loading will no work. The filter is trying to solve it by always opening session in every request and closing it at the end. Tapestry hibernate opens session only when it is needed and closes it when thread is finished, it is how it should be, but if you use spring hibernate + tx you need to use it there is no way around it. Denis May 22, 2012 v 3:59 PM, bhorvat: The thing is I am not sure for what it is used in the first place. Based on everything that I have read it it seams to me that you use it to keep the session open until you are done with the rendering of the tml. Say that you load an object and that object has a list of objects in it, and you try to access the list in the tml page with say the loop component. Now if you dont use the OpenSessionInViewFilter you should get an exception (LazyInitalization). However I dont get that exception, so I was wondering (since most of the stuff for OSIVF is a bit old) is tapestry now handling this itself (tapestry-hibernate that is) or am I miss understanding what the filter is used for in the first place? I would like to solve 2 problems with this transaction. The first one is the LazyInitalization. I always have to reload the object in the methods that handle the form if I need to use some list of objects that have not been used when the page was rendered.

Re: high thread contention during load test on InternalComponentResourcesImpl.postRenderCleanup and org.apache.tapestry5.internal.util.NamedSet.getValues
Would it be better to put synchronized block inside null check block like:

If I'm not mistaken resetParametersConduits doesn't need to be synchronized it
should only change per thread value.
Denis
May 11, 2012 v 6:06 PM, Howard Lewis Ship:
That's an interesting result. Why, oh why, did I ever implement
render variables?
So the conventional thinking on synchronized methods is that they
where there is limited contention, and the method is short,
synchronized is the best way to go.
This method exists, and is synchronized, to avoid creating a
PerThreadValue to store the render variable's Map on every component
and mixin in the application. That adds up, given that only a tiny
percentage of pages or components will ever use a render variable.
I'd be willing to replace this code with something that uses an
explicit per-instance Lock ... that would likely help with your high
contention issues, as after the PerThreadValue is created, and the
write lock is released, there would no longer be contention, as all
threads could share the read lock.
I can put that together shortly and crank out a 5.3.4-rc-1 snapshot,
if you can then pick it up and test it.

Is there a workaround possible without removing the Loop component from

Re: Why not setter injection or thread-safe field @Inject?
Where did you read about fields injection not being thread safe? It's definitely not true. Some developers like to use constructor injection because of better testing etc. personally I'm using mostly field injection. Setter injection is just not implemented, IMHO IOC should support method injection when it's annotated with @Inject just like JSR-330 describes it. Denis Mar 20, 2012 v 10:01 AM, Ferran Maylinch: Hello, Reading the documentation, I assume Tapestry does not perform setter injection (like Spring). Also, I've read that @Inject directly into fields is not thread-safe so constructor injection or build* methods are the recommended ways. I wonder why Tapestry does not allow setter injection and thread-safe @Inject if build* methods are already thread-safe (aren't they?). Setter injection would be something similar: Tapestry would instantiate the service and set dependencies before letting anyone use the service (as I presume it does with build* methods). Field @Inject would be something similar too. Thank you - To unsubscribe, e-mail: users-unsubscr...@tapestry.apache.org For additional commands, e-mail: users-h...@tapestry.apache.org

Re: ComponentParameters - Binding Expressions - component:
The pattern that Paul and Thiago are suggesting works fine if that component
occurs a single time on a page. However, if you use it multiple times, the
client side zoneId (as well as the Tapestry JS initializers) are not unique
any more, which causes the same zone to be updated all the time, no matter
which EventLink got the click.
Again and again randomly generated zone id confuses developers. :)

Maybe it would be better to have the web service handling in a singleton service (and initializes wsld and xml stuff there) which is injected into the thread scoped - this might work as well.

Re: ActivationRequestParameter only works in a page?
I have something like this implemented in our app for component events only, a field with the special annotation will add its value as a request parameter to all links inside rendering phase and on incoming event the special filter will send restore event to restore field's previous value. Works great with deep component hierarchy, otherwise you need to preserve that state using context in all events, which is very ugly.

Re: @Property and existing getter or setter
...by adding @Property you're asking for a getter / setter pair that are benign in operation and have no side effects whereas your own getters and setters could do anything. If you have a nefarious setter but don't notice it because you were blinded by the @Property annotation I can foresee bugs creeping into code which would be hard to track down. sure, only when you expect that @Property will fail if you already have getter/setter, 5.2 used to overload methods from superclass… anyway you can also mistype onevent method and wondering what went wrong With live page reloading, surely the time taken to add (write=false) and click refresh is negligible, no? our app reloads between 10-20seconds so it does matter right now, 5.3 should improve it Denis Oct 18, 2011 v 1:26 PM, Steve Eynon: Steve.

Re: Compiled CSS
If I understand it correctly, right now resources accesses with ResourceTransformer will have same url as the source. It would be nice to have somekind of transform resources mapping, lets say we want to transform less file or files to css: virtualTransformResource(/css/bootstrap.css, /less/bootstrap.less) - virtual resource /css/bootstrap.css will be resource /less/bootstrap.less transformed using ResourceTransformer, mimetypes are extracted from file names. Transforming all files from specified context: virtualTransformContext( /css/, /less/, text/css, text/less) - with additional from/to mimetypes to recognize what kind of files need to be transformed.

Re: Tapestry upload and Google App Engine

Re: Tapestry upload and Google App Engine
Override FileItemFactory using IOC: http://tapestry.apache.org/ioc-cookbook-overriding-ioc-services.html your FileItemFactory implementation will need to return simple implemention of FileItem, request is writing a file using outputstream, so you need a ByteArrayOutputStream to write to. http://commons.apache.org/fileupload/apidocs/org/apache/commons/fileupload/FileItemFactory.html http://commons.apache.org/fileupload/apidocs/org/apache/commons/fileupload/FileItem.html Denis On 20.8.2011, at 10:45, bhorvat wrote: I know what the problem is the problem, I have read in couple of places a general idea what one should do about all of this but sadly I do not possess the necessary knowledge to implement that.

Re: Tapestry upload and Google App Engine
From what I can see I will need to include this gwtupload library using mave
and then use that to handle the file uploading and saving into Blob, right?
You only need to replace the FileItemFactory with an implementation which will
store files in memory or specific GAE place, try to use gwtupload lib.
Include something like this into your Tapestry module:
@Contribute(ServiceOverride.class)
public static void
overrideFileItemFactory(MappedConfigurationClass,Object configuration)
{
configuration.addInstance(FileItemFactory.class,
FilesApiFileItemFactory.class);
}
But how do you use this into tapestry? You cant use their normal upload
component. So do I have to create a normal form (not t:form).
You should be able to use the upload component.
Did someone try this?
I didn't.

Re: Tapestry upload and Google App Engine
Now if I understand you correctly I can use tapestry-upload component like I would normally do, right? Yes One thing that I don't understand is how to I save the file into Blob? In normal application I would create a t:form with t:upload inside it. Then in the java file I would create a property for that field from the class UploadedFile Same here and then I would use that class to write the file to disk. But how do I do that or how do I save it into Blob? I don't know, you need to use GAE API, use getStream from UploadFile to read the file and write it somewhere, take a look how does the FilesApiFileItemFactory do it. http://code.google.com/p/gwtupload/source/browse/trunk/GwtUpload/gae/src/main/java/gwtupload/server/gae/FilesApiFileItemFactory.java?r=884 Denis
Re: What place the @Persist will invalid
You can't persist UploadFile because it's content is deleted one the end od the
request.
After a file is uploaded read the data to the byte array.

Hi Dick
I am not sure If I fully understand the question but here is my review
of the code.
You are using 'files' instance variable to store all the files but the
component is using 'value' as a parameter which will obviously be
null.
Remove
@Parameter(required = true, autoconnect = true)
private ListUploadedFile value;
@Persist
private ListUploadedFile files;
instead add this
@Parameter(required = true, autoconnect = true)
private ListUploadedFile files;
and ensure you pass a persist field to the component
t:swfupload t:id=files/
public class MyPage {
@Persist
@Property
private ListUploadFile files;
}
also you are not using it inside a form so don't extend AbstractField,
remove processSubmission() and removeNull...()

Re: IOC Setter injection
I haven't found any code related to setter injection.
I'm researching if it is possible to convert some old spring beans into using
Tapestry IOC without a lot of work. Anonymous setter injection is the only way
how to achieve it.

Yes, but not using autobuilding. Use a builder method instead:
public static YourService buildYourService(DependencyType1 type1, ...) {
YourService service = new ...;
service.setDependencyType1(type1);
return build;
}

I have found this article http://blog.tapestry5.de/index.php/2011/01/17/javax-inject-inject-support-in-tapestry/ which tells that Tapestry supports setter injection by default but i can't find any reference in documentation or source code.

Component context @ActivationRequestParameter
Hello everyone,
we are using tapestry in our ajax application, most web actions like creating,
editing etc. are implemented using modal dialogs, problem is that only easy way
how to store context is to put it in page link (on Activate approach).
Now, if you think about switching page navigation layout to ajax layout with
one page, you need to pass your context in all your component events.
Example: EditUserPage is replaced with EditUserComponent and it is showed as
the modal dialog when a user clicks on the edit link from UserAllPage, problem
here is that all other component events in EditUserComponent should also have
context as parameter and that you need to pass context to all child components
of EditUserComponent.
I have created my own component annotation like @ActivationRequestParameter
which adds query parameter to all component links in that component body, in
setupRender phase it adds link listener to thread scope LinkCreationHub and in
clearRender phase it removes listener. Also there is a component event filter
which triggers events to set parameter back when finds query parameter with
specific prefix, and also adds his own listener to delegate query parameters to
other component events. It works for me, you can just annotate your context
properties in EditUserComponent and they will be restored on next component
event like onShowDetail() { return detailBlock; };
There is a lot of use cases for that component context annotation approach
using ajax.
I would like to see something like that in 5.2, my implementation is 5.1 old
(javassist worker etc) and maybe you have a better idea how to implement it. I
know that it's a not a perfect solution, the component need to be rendered
because of setupRender hook, it's not possible to use activate event because
components are not activated.
Thanks,
Denis
