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.

- -

Note that mod_dav_fs does not need this - generic locking module, because it uses its own more specialized - version.

- -

In order to make mod_dav_lock functional, you just have - to specify the location of the lock database using the DavGenericLockDB directive described - below.

- - Developer's Note -

In order to retrieve the pointer to the locking provider function, you - have to use the ap_lookup_provider API with the arguments - dav-lock, generic, and 0.

- - -mod_dav - - -DavGenericLockDB -Location of the DAV lock database -DavGenericLockDB file-path -server configvirtual host -directory - - - -

Use the 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.

- - Example - - DavGenericLockDB var/DavLock - - - -

The directory containing the lock database file must be - writable by the User - and 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.

Les utilisateur et groupe sous lesquels Apache s'exécute et qui - sont respectivement définis par les directives User et Group doivent pouvoir écrire dans le - répertoire qui contient le fichier de la base de données des - verrous. Pour des raisons de sécurité, il est recommandé de créer un - répertoire dédié à la base de données des verrous, plutôt que de - modifier les permissions d'un répertoire existant.
