This document describes how to add support for extended webdav features (locking,
|
||
|
properties etc.) to your webdav-aware application.
|
||
|
Author: Hamish Rodda, rodda@kde.org
|
||
|
Version: 0.3
|
||
|
|
||
|
Compatable with (tested on):
|
||
|
Apache + mod_dav version 1 and 2
|
||
|
Zope
|
||
|
Silverstream webdav server
|
||
|
|
||
|
Applications supporting extended webdav features
|
||
|
(include name and contact email, in case the interface has to change):
|
||
|
[none currently]
|
||
|
|
||
|
Much of the info here is elaborated by rfc #2518; the rest can be understood by reading
|
||
|
davPropStat() in http.cc, specifically the setMetaData() calls.
|
||
|
|
||
|
Extended information is transferred via kio's metadata system...
|
||
|
|
||
|
=== MISCELLANEOUS ===
|
||
|
Display Names (names suitable for presentation to the user) are passed as the metadata
|
||
|
element davDisplayName.
|
||
|
|
||
|
Source template locations (href, usually an absolute URL w/o host info)
|
||
|
are passed as element davSource.
|
||
|
|
||
|
Content languages are passed as element davContentLanguage.
|
||
|
|
||
|
Extra webdav headers are passed as metadata element davHeader
|
||
|
|
||
|
For doing a webdav SEARCH, use listDir() and set the metadata element
|
||
|
davSearchQuery to the search query. The root element of this query should be like
|
||
|
<d:basicsearch> or <d:sql>.
|
||
|
|
||
|
For doing a generic webdav action, call a special request, with
|
||
|
the following data:
|
||
|
int, value 7 (WEBDAV generic)
|
||
|
KURL url
|
||
|
int method - the HTTP/WEBDAV method to call
|
||
|
Send the xml request and receive the xml response in the usual way.
|
||
|
|
||
|
=== CREATING A LOCK ===
|
||
|
To create a lock, call a special request, with the following data:
|
||
|
|
||
|
int, value 5 (LOCK request)
|
||
|
KURL url - the location of the resource to lock
|
||
|
QString scope - the scope of the lock, currently "exclusive" or "shared"
|
||
|
QString type - the type of the lock, currently only "write"
|
||
|
QString owner (optional) - owner contact details (url)
|
||
|
|
||
|
Additionally, the lock timeout requested from the server may be altered from the default
|
||
|
of Infinity by setting the metadata "davTimeout" to the number of seconds, or 0 for
|
||
|
infinity.
|
||
|
|
||
|
=== REMOVING A LOCK ===
|
||
|
To remove a lock, call a special request, with the following data:
|
||
|
|
||
|
int, value 5 (LOCK request)
|
||
|
KURL url - the location of the resource to unlock
|
||
|
|
||
|
metadata required:
|
||
|
davLockToken - the lock token to remove
|
||
|
|
||
|
and, of course, any other lock information as below required for the operation
|
||
|
to suceed.
|
||
|
|
||
|
=== SETTING LOCK INFORMATION ===
|
||
|
To provide lock data so that urls can be accessed, you need to pass the following metadata:
|
||
|
davLockCount: (uint) the number of locks you are providing
|
||
|
davLockToken%1: (string) the token
|
||
|
(optional) davLockURL%1: (string) the absolute URL specified by the lock token
|
||
|
(optional) davLockNot%1: (value ignored) the presence of this meta key negates the lock
|
||
|
(ie. requires the lock to not be set)
|
||
|
|
||
|
Example data:
|
||
|
=============
|
||
|
davLockCount: 2
|
||
|
davLockToken1: opaquelocktoken:f81de2ad-7f3d-a1b2-4f3c-00a0c91a9d76A
|
||
|
davLockNot1: (value ignored)
|
||
|
davLockToken2: opaquelocktoken:f81de2ad-7f3d-a1b2-4f3c-00a0c91a9d76B
|
||
|
davLockURL2: http://www.foo.bar/container2/
|
||
|
|
||
|
|
||
|
=== RECEIVING LOCK INFORMATION ===
|
||
|
For each file, stat/listdir always returns two pieces of information:
|
||
|
|
||
|
davSupportedLockCount: (uint) the number of lock types discovered for this resource.
|
||
|
davLockCount: (uint) the number of locks discovered on this resource.
|
||
|
|
||
|
for each count, additional information is returned:
|
||
|
|
||
|
===================
|
||
|
Information about the locks on a resource:
|
||
|
|
||
|
davLockCount: %1 (the number of locks to be described, as below)
|
||
|
*** Required items ***
|
||
|
davLockScope%1 - The scope of this lock. May be exclusive, shared, or a custom type.
|
||
|
davLockType%1 - The type of the lock.
|
||
|
davLockDepth%1 - The depth to which this lock applies
|
||
|
(0=only this resource, 1=this collection, infinity=applies recursively)
|
||
|
|
||
|
*** Optional items ***
|
||
|
davLockOwner%1 - The owner of this lock.
|
||
|
davLockTimeout%1 - The timeout parameter. Possibilities: see section 9.8, rfc #2518
|
||
|
davLockToken%1 - The token which iden
|
||
|
|
||
|
===================
|
||
|
Information about the lock types supported by the resource
|
||
|
|
||
|
davSupportedLockCount: %1 (the number of locks types to be described, as below)
|
||
|
|
||
|
davSupportedLockScope%1 - The scope of the lock (exclusive, shared, other custom type)
|
||
|
davSupportedLockType%1 - The type of the lock (webdav 1.0 supports only the "write" type)
|
||
