LOCKing a non-existent resouce
Slide allows the locking of a previously
non-existent resource. A couple of
questions.
1. Should this be allowed? I couldn't
find reference to such a condition in RFC2518.
2. If it is allowed, should this appear in IE
Web Folders and if so how? At he moment,
it looks like a directory but
any attempt to copy files into the "directory"
fails with a 409 status code.
Regards
Michael

The next revision of RFC 2518 will change the defined behaviour
of lock-null resources in the following manner:
http://www.webdav.org/wg/rfcdev/issues.htm item 80
LOCK on a non-existing URL (where the collection parent exists)
will create a locked, empty plain resource. The resource cannot
be changed into a collection. When the lock expires, the resource
will stay.
//Stefan
Hint: the MS WebFolder shows everything as a collection where
the DAV:resourcetype property is non-empty.

It means that resource name must disappear from
members list. Basically, this functionality is
provided to reserve names. I have not checked Slide
for this, as I use slide client to talk to NetWare
server and IIS. I have seen on IIS, resource continue
to exist even after unlocking.

If you go by RFC then it should not appear.

The reason for this could be that Server might have
assigned a non-collection resource type to that
resource and hence you can't add members to that.
I don't think IE should assign any type to a resource
on it's own.
Best way to find out these things is to use slide
client and try to add, so you would be able to find
the root cause of the problem. Obviously doing this
will take some time ;)

Thanks for the reference.
It raises a couple of extra questions.
1. The text suggests the resource is NOT a collection.
However this is how it appears in IE Web Folders.
2. Once unlocked, the text says the resource returns
to the NULL state. What does this mean in practice?
Should it still appear as a node in SLIDE? Again,
IE continues to show the resource as a directory, but
won't allow it to have members, presumably because it
doesn't think its a collection.

yes, locking a non-existing resource is allowed (see
sec7.4, rfc2518). I think there must be no resource
type associated with such a resource, as it's null
resource. Only after a PUT or MKCOL request a proper
type can be assigned to such a resource. However,
assigning a type for such a resource may be server
dependent, I guess.
hope it helps!
