|Description:||Generic locking module for
|Compatibility:||Available in version 2.1 and later|
This module implements a generic locking API which can be used by any backend provider of
mod_dav. It requires at least the service of
mod_dav. But without a backend provider which makes use of it, it's useless and should not be loaded into the server. A sample backend module which actually utilizes
mod_dav_lock is mod_dav_svn, the subversion provider module.
mod_dav_fs does not need this generic locking module, because it uses its own more specialized version.
In order to retrieve the pointer to the locking provider function, you have to use the
ap_lookup_provider API with the arguments
|Description:||Location of the DAV lock database|
|Context:||server config, virtual host, directory|
DavGenericLockDB directive to specify the full path to the lock database, excluding an extension. If the path is not absolute, it will be interpreted relative to
ServerRoot. The implementation of
mod_dav_lock uses a SDBM database to track user locks.
The directory containing the lock database file must be writable by the
Group under which Apache is running. For security reasons, you should create a directory for this purpose rather than changing the permissions on an existing directory. In the above example, Apache will create files in the
var/ directory under the
ServerRoot with the base filename
DavLock and an extension added by the server.
