Apache Module mod_dav_lock
Description: | Generic locking module for mod_dav
|
---|---|
Status: | Extension |
ModuleIdentifier: | dav_lock_module |
SourceFile: | mod_dav_lock.c |
Compatibility: | Available in version 2.1 and later |
Summary
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
.
DavGenericLockDB Directive
Description: | Location of the DAV lock database |
---|---|
Syntax: | DavGenericLockDB file-path |
Context: | server config, virtual host, directory |
Status: | Extension |
Module: | mod_dav_lock |
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.
