Hello,

Here is a quota listener developed to manage quotas on Slide.
I would like to propose this listener to the Slide community.
There are probably some improvements to do for example concerning logs and
exception management.

This listener is 98% compliant with the WebDAV quota RFC.

We differ on the following points :

  1. The virtual root notion
  2. We have implemented a "soft" quota management, it means that quota
     could be exceeded one time and only one time putting a resource on
     the server. We would like to implement a classic ("hard") quota
     management in a future version.
     We have decided to choose a "soft" quota management for the
     following reason :
     We have trust in the content-length HTTP header to check if a
     storage action can be done, except for a copy or a move action
     (the resource already exists on the server) we get the resource
     size directly "on the disk". According to the HTTP RFC the
     content-lenght header is optional. When the content-length header
     is not filled in (or equals to -1) we had to calculate the size of
     the resource handling the HTTP input stream. We could not find an
     easy way to do that. Any idea ?

Regards,

Thomas
