setup() called twice in one request
Hello,
we discovered that the setup() method of a custom generator is sometimes
called twice in one request.
We saw in the logs that the following methods were called in that order:
setup
getKey
getValidity
getValidity
setup
...
This does not always happen; in fact, it seem to happens only if the generator
is applied to a document that is an XSL stylesheet.
Is it normal that setup() is called more than once per request, or may it be a
bug?
Can the problem be related to the caching mechanism? (The custom generator is
cacheable; and between the two setup() calls the caching methods were called,
see above)
Our XSL stylesheets usually include other stylesheets. As far as I know, the
caching mechanism takes this into account. May the problem have something to
do with that?
We use Cocoon 2.1.3 and Tomcat 4.1.27 under Linux.
Thanks in advance,
Tilman Rassy

Thank you very mutch for these explanations.
Unfortunately, I'm quite sure that the two setup() calls are from the same
instance and in the same request. We can see that very clearly in the logs. I
included an excerpt from the logs in my reply to the mail from Joerg Heinicke
in this matter. You will find further explanations there, too. If you are
interested in my problem further on, please look there.
Best regards,

Yes, you're right: now, the contract is that setup() is only called once
per request per component instance in the pipeline. So, if you have a
pipeline with one generator, one transformer and one serializer, setup()
is called once on the generator, once on the transformer and once on the
serializer (per request for this pipeline).
Now, if you happen to have the same transformer twice in the pipeline,
like applying two xslts, then of course setup is called twice for the
xslt transformer but on two different instances/objects.

Thank you for the quick reply.
I think we can change our code so that multiple setup() calls are not a
problem any longer. The reasons why I posted anyway are: If there is a bug,
the Cocoon developers might want to know about it. Secondly, we do a lot of
Cocoon programming in our project, and it would be easier for my collegues
and me if we knew the exact rules that apply to the setup() calls.

Hello,
Assuming it is the case, why is it a problem? Can you elaborate
on that?

Good news: It seems that the problem does not occur with Cocoon 2.1.8! At
least I did not notice any double setup() calls yet, whereas in similar tests
with Cocoon 2.1.3 I noticed them.
Thank you all for your help, and sorry for bothering you with a problem that
has already been fixed in the current version!
Best regards,
Tilman

We have fixed several problems/bugs in the sitemap source and pipeline
implementations after the 2.1.3 release. So I think the best thing for
you is to test your test case with the most recent version (2.1.8) and
see if this problem still exists.

OK. I have no idea how to get the source for xmlutil-1.0-dev. I was
looking at the current source and the 2.1.7 source (the oldest I have)
and it looks to me that if there is a problem it is most likely in
XSLTProcessorImpl. However, I'd suggest you look at SitemapSource and
AbstractProcessingPipeline in your source and see if anything screwy is
going on.

Can you send the source for the DocumentGenerator? I'd love to see it.

Thank you both for your advice. I did it that way and it worked fine.

You can also just do new Throwable() and then print it.

You don't have to throw it. Just
getLogger.debug("myException", new MyExcpetion());
should be enought.

Is there a way to create a stack trace and insert it into the logs? I could do
something like
try
{
throw new MyExcpetion();
}
catch (MyException myExcpetion)
{
this.getLogger.debug( /* get stack trace from myException */ );
}
in the setup() method. Would that work?

Sure :)
Can you provide a stack trace for the two calls of the setup() method,
so we can see from where this method is called.
Thanks

In the case of the request with the two setup() calls, it is not called at
all. Probably the response is taken from the cache. In other cases, when it
is called, it is called only once.
One thing I should mention is that in all cases the response is not corrupted.
What we see in the browser is exactly what we expect.

Yes, I will try to create one. However, since our system contains a lot of
code and data, it may take a little time to extract a testcase from it.

Strange, what about the generate() method? When is that one called?
Twice as well?
Now, the best thing would be if you could provide a reproducable test
case for us.

I'm quite sure that it is the same request and the the same generator instance

----------- log excerpt end ---------
"DocumentGenerator#2" means "DocumentGenerator instance with instance id 2".
The instance id is a unique number attached to each instance, so you can see
that both setup() calls are from the same generator instance. Also, the URI
and the thread are the same.
Another striking fact is that between the two setup calls, no recycle is
called.

The purpose of the generator is to get documents from a database, create XML
representations of them and send them to the pipeline. The documents are of
various types. One of the types is "XSL stylesheet". Only with this type the
problem occurs (as far as we know).
Any more ideas/help are welcome,

Yes. The include URL use the "cocoon:" pseudo-protocol. The URL points to a
pipeline that takes a stylesheet from a database, does some transformation,
and seralizes it.
If you are interested in more detailes on my problem (of corse I hope you
are ;-), please see my reply to the mail from Ralph Goers. You will also find
an excerpt from the logs there.

Are you including the other stylesheets using a cocoon pipeline as the url?

Are you sure that it is only one request. For example using the Acrobat
Reader in IE results in two requests.

What does this mean?

For normal circumstances this sounds a bit weird indeed :)

AFAIK the caching calls are ok up to the first getValidity. I don't know
why it is called twice.

In the past the problem was more in the other direction: Cocoon did not
detect all changes to included stylesheets, only a change to the root
stylesheet caused a reload. So I don't think this causes the problem -
but you never know ;)
