Re: slide 2.2 release

Hello Antoine !

The quota Listener is a development for Slide to manage quotas according 
to the draft dealing with this topic 
(http://www3.ietf.org/proceedings/05mar/IDs/draft-ietf-webdav-quota-06.txt).

You will find a presentation of this development here :
http://www.esup-portail.org/consortium/espace/Stockage_2F/serveur/serveur_V4/media/ESUPWebDAV.pdf
and a more general documentation about the Slide based ESUP-Portail 
WebDAV server here :
http://www.esup-portail.org/consortium/espace/Stockage_2F/serveur/serveur_V4/index.html

How does the listener work in few words...
When a WebDAV request comes to Slide, Slide throws "events" (put event, 
delete event...) just before and just after doing the job.
The quota listener catch these events and for actions needing quota 
management (put, delete, move...) :
- before the action : check that the action will not lead to an 
overquota - if it does, the quota listener throws a 507 error ("quota 
exceeded")
- after the action : update the quota metadata

Note that the ESUP-Portail consortium has added the optional option of 
"virtual root" (cf. 
http://www.esup-portail.org/consortium/espace/Stockage_2F/serveur/serveur_V4/media/ESUPWebDAV.pdf)

Given that quota metadata are protected (propatch are not possible to 
initialize/modify these metadata), the ESUP-Portail consortium has 
developed :
- a Web service for Slide to handle quota metadata
- a client requesting this Web service to manage quota metadata

I will make a new Slide bugzilla entry with the lastest modifications.
Feel free to contact me for further details.

Regards,

Thomas
