A server is of course free to refuse the DELETE request,
and indicate as its reason that it didn't want to satisfy
the postcondition that would remove that version URL from
the DAV:merge-set.

Note thought that even if the server allows the deletion,
there is no race condition here, though,
just some dangling version URL's that will return 404's
when accessed.

Subject: Versions being deleted during a MERGE...


I just noticed a potential problem with versions being used for a merge
being deleted during the merge.

Section 11 says a checked-out resource has a DAV:merge-set identifying
to be merged.  DELETE (section 11.5) says it will remove entries from
merge-set.  Shouldn't the server disallow the DELETE, someone somewhere
is in the
middle of a merge using this version, also there would be a race
condition if someone
deletes the version while the client is processing the DAV:merge-set of
a checked-out
