mod_dav_svn Configuration Directives — Apache configuration directives for serving Subversion repositories through the Apache HTTP Server.
This section briefly describes each Subversion Apache configuration directive. For an in-depth description of configuring Apache with Subversion, see the section called “httpd, the Apache HTTP Server”.
These are the httpd.conf directives
          that apply to mod_dav_svn:
DAV svn
              
            Must be included in any
                Directory or
                Location block for a Subversion
                repository.  It tells httpd to use the Subversion
                backend for mod_dav to handle all
                requests.
SVNActivitiesDB
              directory-path
              
            Specifies the location in the filesystem where the
                activities database should be stored.  By default,
                mod_dav_svn creates and uses a directory in the
                repository
                called dav/activities.d.  The
                path specified with this option must be an absolute
                path.
If specified for
                an SVNParentPath area, mod_dav_svn
                appends the basename of the repository to the path
                specified here.  For example:
<Location /svn> DAV svn # any "/svn/foo" URL will map to a repository in # /net/svn.nfs/repositories/foo SVNParentPath "/net/svn.nfs/repositories" # any "/svn/foo" URL will map to an activities db in # /var/db/svn/activities/foo SVNActivitiesDB "/var/db/svn/activities" </Location>
SVNAdvertiseV2Protocol On|Off
              
            New to Subversion 1.7, this toggles
                whether mod_dav_svn advertises its
                support for the new version of its HTTP protocol also
                introduced in that version.  Most admins will not wish
                to use this directive (which is On
                by default), choosing instead to enjoy the performance
                benefits that the new protocol offers.  However, whena
                configuring a server as a write-through proxy to
                another server which does not support the new
                protocol, set this directive's value
                to Off.
SVNAllowBulkUpdates On|Off
              
            Toggles support for all-inclusive
                responses to update-style REPORT
                requests.  Subversion clients use
                REPORT requests to get information
                about directory tree checkouts and updates from
                mod_dav_svn.  They can ask the
                server to send that information in one of two ways:
                with the entirety of the tree's information in one
                massive response, or with a
                skelta (a skeletal
                representation of a tree delta) which contains just
                enough information for the client to know what
                additional data to request from
                the server.  When this directive is included with a
                value of Off,
                mod_dav_svn will only ever respond
                to these REPORT requests with
                skelta responses, regardless of the type of responses
                requested by the client.
Most folks won't need to use this directive at
                all.  It primarily exists for administrators who
                wish—for security or auditing reasons—to
                force Subversion clients to fetch individually all the
                files and directories needed for updates and
                checkouts, thus leaving an audit trail of
                GET and PROPFIND
                requests in Apache's logs.  The default value of this
                directive is On.
SVNAutoversioning On|Off
              
            When its value is
                On, allows write requests from
                WebDAV clients to result in automatic commits.  A
                generic log message is auto-generated and attached to
                each revision.  If you enable autoversioning, you'll
                likely want to set ModMimeUsePathInfo
                On so that mod_mime can
                set svn:mime-type to the correct
                MIME type automatically (as best as
                mod_mime is able to, of course).
                For more information, see Appendix C, WebDAV and Autoversioning.  The default value of this
                directive is Off.
SVNCacheFullTexts On|Off
              
            When set to On, this tells
                Subversion to cache content fulltexts if sufficient
                in-memory cache is available, which could offer a
                significant performance benefit to the server.  (See
                also the SVNInMemoryCacheSize
                directive.)  The default value of this directive
                is Off.
SVNCacheTextDeltas On|Off
              
            When set to On, this tells
                Subversion to cache content deltas if sufficient
                in-memory cache is available, which could offer a
                significant performance benefit to the server.  (See
                also the SVNInMemoryCacheSize
                directive.)  The default value of this directive
                is Off.
SVNCompressionLevel
              level
              
            Specifies the compression level used when sending
                file content over the network.  A value
                of 0 disables compression
                altogether, and 9 is the maximum
                value.  5 is the default
                value.
SVNIndexXSLT
              directory-path
              
            Specifies the URI of an XSL transformation for directory indexes. This directive is optional.
SVNInMemoryCacheSize
              size
              
            Specifies the maximum size (in kbytes) per process
                of Subversion's in-memory object cache.  The default
                value is 16384; use a value
                of 0 to deactivate this cache
                altogether.
SVNListParentPath On|Off
              
            When set to On, allows
                a GET
                of SVNParentPath, which results in
                a listing of all repositories under that path.  The
                default setting is
                Off.
SVNMasterURI
              url
              
            Specifies a URI to the master Subversion repository (used for a write-through proxy).
SVNParentPath
              directory-path
              
            Specifies the location in the filesystem of a
                parent directory whose child directories are
                Subversion repositories.  In a configuration block for
                a Subversion repository, either this directive or
                SVNPath must be present, but not
                both.
SVNPath
              directory-path
              
            Specifies the location in the
                filesystem for a Subversion repository's files.  In a
                configuration block for a Subversion repository,
                either this directive or
                SVNParentPath must be present, but
                not both.
SVNPathAuthz On|Off|short_circuit
              
            Controls path-based authorization by enabling
                subrequests (On), disabling
                subrequests (Off; see the section called “Disabling path-based checks”),
                or querying mod_authz_svn directly
                (short_circuit).  The default
                value of this directive is On.
SVNReposName
              name
              
            Specifies the name of a Subversion repository for
                use in HTTP GET responses.  This
                value will be prepended to the title of all directory
                listings (which are served when you navigate to a
                Subversion repository with a web browser).  This
                directive is optional.
SVNSpecialURI
              component
              
            Specifies the URI component (namespace) for
                special Subversion resources.  The default is
                !svn, and most
                administrators will never use this directive.  Set
                this only if there is a pressing need to have a file
                named !svn in your repository.
                If you change this on a server already in use, it will
                break all of the outstanding working copies, and your
                users will hunt you down with pitchforks and flaming
                torches.
