svnserve allows access to Subversion repositories using Subversion's custom network protocol.
You can run svnserve as a standalone
server process (for clients that are using the
svn:// access method); you can have a daemon
such as inetd or xinetd
launch it for you on demand (also for
svn://), or you can have
sshd launch it on demand for the
svn+ssh:// access method.
Regardless of the access method, once the client has
selected a repository by transmitting its URL,
svnserve reads a file named
conf/svnserve.conf in the repository
directory to determine repository-specific settings such as
what authentication database to use and what authorization
policies to apply. See the section called “svnserve, a Custom Server” for details of the
svnserve.conf file.
Unlike the previous commands we've described, svnserve has no subcommands—it is controlled exclusively by options.
--daemon (-d)
Causes svnserve to run in daemon
mode. svnserve backgrounds itself
and accepts and serves TCP/IP connections on
the svn port (3690, by
default).
--foreground
When used together with -d,
causes svnserve to stay in the
foreground. This is mainly useful for debugging.
--inetd (-i)
Causes svnserve to use the
stdin and stdout file descriptors, as is appropriate for a
daemon running out of inetd.
--help (-h)
Displays a usage summary and exits.
--listen-host
HOST
Causes svnserve to listen on the
interface specified by HOST,
which may be either a hostname or an IP address.
--listen-once (-X)
Causes svnserve to accept one
connection on the svn port, serve it,
and exit. This option is mainly useful for
debugging.
--listen-port
PORT
Causes svnserve to listen on
PORT when run in daemon mode.
(FreeBSD daemons listen only on tcp6 by default—this
option tells them to also listen on tcp4.)
--pid-file
FILENAME
Causes svnserve to write its
process ID to FILENAME, which
must be writable by the user under
which svnserve is running.
--root (-r)
ROOT
Sets the virtual root for repositories served by svnserve. The pathname in URLs provided by the client will be interpreted relative to this root and will not be allowed to escape this root.
--threads (-T)
When running in daemon mode, causes svnserve to spawn a thread instead of a process for each connection (e.g., for when running on Windows). The svnserve process still backgrounds itself at startup time.
--tunnel (-t)
Causes svnserve to run in tunnel
mode, which is just like the inetd
mode of operation (both modes serve one connection over
stdin/stdout, and then exit), except that the connection
is considered to be preauthenticated with the username
of the current UID. This flag is automatically passed
for you by the client when running over a tunnel agent
such as ssh. That means there's
rarely any need for you to pass
this option to svnserve. So, if you
find yourself
typing svnserve --tunnel on the
command line and wondering what to do next, see
the section called “Tunneling over SSH”.
--tunnel-user NAME
Used in conjunction with the --tunnel
option, tells svnserve to assume that
NAME is the authenticated
user, rather than the UID of the svnserve
process. This is useful for users wishing to share a single
system account over SSH, but to maintain separate commit
identities.
--version
Displays version information and a list of repository backend modules available, and then exits.
