Quotas again.
Hello,
I have read on the mailing list that in 2001 somebody started to develop
Slide quota based on Interceptors, but apparently that development was
not completed (do you know why ?).
Is there somewhere a sample of code about this work ?
A technical question :
A class "InsufficientStorageException" exists but is never used. To be
compliant with the "draft-ietf-webdav-quota-06" I would need to throw
this kind of exception in some classes in my Interceptor. Is there a
reason for this absence ? Would it be possible to modify the interface
"ContentInterceptor" to include it ?
Thank you.
Thomas

This was because in 2001 event in slide does not exists. There were only
Interceptors before ... now, there are events and extractor.

no problem with that for me.

Ok, I will do that. Before starting my development, I just wanted to
study all the different possibilities and as somedy started to develop
Slide quotas based on Interceptors, I thought it could be a way. But I
will follow your advice.
Sorry for my basic questions, I am not very aware of event and
interceptors yet. ;-)
Thank you very much for your help. (Thanks to Stephan too)

One's again look at the events system. Events are pretty much flexible
than Interceptors and this is not very difficult to convert an
ContentInterceptor to an EventListener.
Listener can throw a VetoException (if vetoable event) ...
then just do something like that
throw (VetoException) new VetoException("no more disk
space").initCause(new InsufficientStorageException(uri, user, "quota
exceded"));
Have a nice day.
Honoré David.

I see the point. But adding InsufficientStorageException the the
ContentInterceptor interface would make a lot of changes necessary
in ContentImpl, in Content etc. ...
Would be good if we find a simpler may. May be you should try not to
use the Interceptor but an event listener (see DetailedWebdavListener
that gets events similar to ContentIntercetor). This is closer to the
WebDAV layer and so its easyer to get the exceptions in to WebDAV response
codes.

I have found a sample of code in the mailing list - mail by
Jean-Philippe Courson ( Tue, 18 Dec 2001 17:10:03) (the mail I was
speaking about in my first message)
Why wasn't his code included in Slide ?
