DESCRIPTION
-----------
A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT"
-aka 9418. It waits for a connection, and will just execute "git-upload-pack"
-when it gets one.
-
-It's careful in that there's a magic request-line that gives the command and
-what directory to upload, and it verifies that the directory is ok.
+aka 9418. It waits for a connection asking for a service, and will serve
+that service if it is enabled.
It verifies that the directory has the magic file "git-daemon-export-ok", and
it will refuse to export any git directory that hasn't explicitly been marked
-for export this way.
+for export this way (unless the '--export-all' parameter is specified). If you
+pass some directory paths as 'git-daemon' arguments, you can further restrict
+the offers to a whitelist comprising of those.
+
+By default, only `upload-pack` service is enabled, which serves
+`git-fetch-pack` and `git-peek-remote` clients that are invoked
+from `git-fetch`, `git-ls-remote`, and `git-clone`.
-This is ideally suited for read-only updates, ie pulling from git repositories.
+This is ideally suited for read-only updates, i.e., pulling from
+git repositories.
OPTIONS
-------
+--strict-paths::
+ Match paths exactly (i.e. don't allow "/foo/repo" when the real path is
+ "/foo/repo.git" or "/foo/repo/.git") and don't do user-relative paths.
+ git-daemon will refuse to start when this option is enabled and no
+ whitelist is specified.
+
+--base-path::
+ Remap all the path requests as relative to the given path.
+ This is sort of "GIT root" - if you run git-daemon with
+ '--base-path=/srv/git' on example.com, then if you later try to pull
+ 'git://example.com/hello.git', `git-daemon` will interpret the path
+ as '/srv/git/hello.git'.
+
+--interpolated-path=pathtemplate::
+ To support virtual hosting, an interpolated path template can be
+ used to dynamically construct alternate paths. The template
+ supports %H for the target hostname as supplied by the client but
+ converted to all lowercase, %CH for the canonical hostname,
+ %IP for the server's IP address, %P for the port number,
+ and %D for the absolute path of the named repository.
+ After interpolation, the path is validated against the directory
+ whitelist.
+
+--export-all::
+ Allow pulling from all directories that look like GIT repositories
+ (have the 'objects' and 'refs' subdirectories), even if they
+ do not have the 'git-daemon-export-ok' file.
+
--inetd::
- Have the server run as an inetd service.
+ Have the server run as an inetd service. Implies --syslog.
+ Incompatible with --port, --listen, --user and --group options.
+
+--listen=host_or_ipaddr::
+ Listen on an a specific IP address or hostname. IP addresses can
+ be either an IPv4 address or an IPV6 address if supported. If IPv6
+ is not supported, then --listen=hostname is also not supported and
+ --listen must be given an IPv4 address.
+ Incompatible with '--inetd' option.
+
+--port=n::
+ Listen on an alternative port. Incompatible with '--inetd' option.
+
+--init-timeout::
+ Timeout between the moment the connection is established and the
+ client request is received (typically a rather low value, since
+ that should be basically immediate).
+
+--timeout::
+ Timeout for specific client sub-requests. This includes the time
+ it takes for the server to process the sub-request and time spent
+ waiting for next client's request.
+
+--syslog::
+ Log to syslog instead of stderr. Note that this option does not imply
+ --verbose, thus by default only error conditions will be logged.
+
+--user-path, --user-path=path::
+ Allow ~user notation to be used in requests. When
+ specified with no parameter, requests to
+ git://host/~alice/foo is taken as a request to access
+ 'foo' repository in the home directory of user `alice`.
+ If `--user-path=path` is specified, the same request is
+ taken as a request to access `path/foo` repository in
+ the home directory of user `alice`.
+
+--verbose::
+ Log details about the incoming connections and requested files.
+
+--reuseaddr::
+ Use SO_REUSEADDR when binding the listening socket.
+ This allows the server to restart without waiting for
+ old connections to time out.
+
+--detach::
+ Detach from the shell. Implies --syslog.
+
+--pid-file=file::
+ Save the process id in 'file'.
+
+--user=user, --group=group::
+ Change daemon's uid and gid before entering the service loop.
+ When only `--user` is given without `--group`, the
+ primary group ID for the user is used. The values of
+ the option are given to `getpwnam(3)` and `getgrnam(3)`
+ and numeric IDs are not supported.
++
+Giving these options is an error when used with `--inetd`; use
+the facility of inet daemon to achieve the same before spawning
+`git-daemon` if needed.
+
+--enable-service, --disable-service::
+ Enable/disable the service site-wide per default. Note
+ that a service disabled site-wide can still be enabled
+ per repository if it is marked overridable and the
+ repository enables the service with an configuration
+ item.
+
+--allow-override, --forbid-override::
+ Allow/forbid overriding the site-wide default with per
+ repository configuration. By default, all the services
+ are overridable.
+
+<directory>::
+ A directory to add to the whitelist of allowed directories. Unless
+ --strict-paths is specified this will also include subdirectories
+ of each named directory.
+
+SERVICES
+--------
+
+upload-pack::
+ This serves `git-fetch-pack` and `git-peek-remote`
+ clients. It is enabled by default, but a repository can
+ disable it by setting `daemon.uploadpack` configuration
+ item to `false`.
+
+EXAMPLES
+--------
+git-daemon as inetd server::
+ To set up `git-daemon` as an inetd service that handles any
+ repository under the whitelisted set of directories, /pub/foo
+ and /pub/bar, place an entry like the following into
+ /etc/inetd all on one line:
++
+------------------------------------------------
+ git stream tcp nowait nobody /usr/bin/git-daemon
+ git-daemon --inetd --verbose
+ --syslog --export-all
+ /pub/foo /pub/bar
+------------------------------------------------
+
+
+git-daemon as inetd server for virtual hosts::
+ To set up `git-daemon` as an inetd service that handles
+ repositories for different virtual hosts, `www.example.com`
+ and `www.example.org`, place an entry like the following into
+ `/etc/inetd` all on one line:
++
+------------------------------------------------
+ git stream tcp nowait nobody /usr/bin/git-daemon
+ git-daemon --inetd --verbose
+ --syslog --export-all
+ --interpolated-path=/pub/%H%D
+ /pub/www.example.org/software
+ /pub/www.example.com/software
+ /software
+------------------------------------------------
++
+In this example, the root-level directory `/pub` will contain
+a subdirectory for each virtual host name supported.
+Further, both hosts advertise repositories simply as
+`git://www.example.com/software/repo.git`. For pre-1.4.0
+clients, a symlink from `/software` into the appropriate
+default repository could be made as well.
+
+
+git-daemon as regular daemon for virtual hosts::
+ To set up `git-daemon` as a regular, non-inetd service that
+ handles repositories for multiple virtual hosts based on
+ their IP addresses, start the daemon like this:
++
+------------------------------------------------
+ git-daemon --verbose --export-all
+ --interpolated-path=/pub/%IP/%D
+ /pub/192.168.1.200/software
+ /pub/10.10.220.23/software
+------------------------------------------------
++
+In this example, the root-level directory `/pub` will contain
+a subdirectory for each virtual host IP address supported.
+Repositories can still be accessed by hostname though, assuming
+they correspond to these IP addresses.
---port::
- Listen on an alternative port.
