I thought you all would be interested in this new development from the IETF meeting:
Lisa Dusseault (my boss, temporary DAV chair) and this guy from Apple wrote up a draft for a DAV Quota spec.
Basically, they added 2 new properties:
DAV:Quota (in bytes) and
DAV:QuotaUsed (in bytes).
We could use that information in the response to df instead of just saying 7777777 100% or 0 0 0 0%.
We (Xythos) also want to include info on bandwidth quotas, but that's less interesting for davfs, I think.
It's good properties.
Anyway, is there any server that support this properties?
Maybe Xythos file server or something?
no, not yet. maybe in a few months.
you know how it is with closed source software...
The iDisk server supports this property. We are planning to support the slightly modified Internet Draft proposal but for now quota/quota-used are supported.
BTW, the webdavfs code in MacOSX has been released to the opensource community and is available at http://www.opensource.apple.com.
I would love to see some collaboration from both opensource filesystems. Digest support/cache improvements/etc.
Really iDisk does DAV:quota and DAV:quota-used? Or is it "some-apple-namespace:quota"? I think we're still using the Xythos namespace for the quota property at Xythos.
The iDisk server uses the DAV: namespace.
The flaw we made was to use 512 byte units in the response in lieu of something more platform independent like bytes - hence the change in the spec. :-)
We will change the iDisk server to match the spec soon ...
Actually,these names will be changed with the next release of the draft. 'quotaused' is going to be 'space-used-bytes' to indicate that it's not dependent on quota and that it's measured in bytes. (Jim Whitehead's suggestion)
Similarly, 'quota' will be 'quota-bytes'.
If there's a rush to put out another draft, I can do so.
