  21DESCRIPTION
  22-----------
  23A really simple TCP git daemon that normally listens on port "DEFAULT_GIT_PORT"
  24aka 9418.  It waits for a connection asking for a service, and will serve
  25that service if it is enabled.
  26
  27It verifies that the directory has the magic file "git-daemon-export-ok", and
  28it will refuse to export any git directory that hasn't explicitly been marked
  29for export this way (unless the '--export-all' parameter is specified). If you
  30pass some directory paths as 'git-daemon' arguments, you can further restrict
  31the offers to a whitelist comprising of those.
  32
  33By default, only `upload-pack` service is enabled, which serves
  34`git-fetch-pack` and `git-ls-remote` clients, which are invoked
  35from `git-fetch`, `git-pull`, and `git-clone`.
  36
  37This is ideally suited for read-only updates, i.e., pulling from
  38git repositories.
  39
  40An `upload-archive` also exists to serve `git-archive`.
  41
  42OPTIONS
  43-------
  44--strict-paths::
  45        Match paths exactly (i.e. don't allow "/foo/repo" when the real path is
  46        "/foo/repo.git" or "/foo/repo/.git") and don't do user-relative paths.
  47        git-daemon will refuse to start when this option is enabled and no
  48        whitelist is specified.
  49
  50--base-path::
  51        Remap all the path requests as relative to the given path.
  52        This is sort of "GIT root" - if you run git-daemon with
  53        '--base-path=/srv/git' on example.com, then if you later try to pull
  54        'git://example.com/hello.git', `git-daemon` will interpret the path
  55        as '/srv/git/hello.git'.
  56
  57--base-path-relaxed::
  58        If --base-path is enabled and repo lookup fails, with this option
  59        `git-daemon` will attempt to lookup without prefixing the base path.
  60        This is useful for switching to --base-path usage, while still
  61        allowing the old paths.
  62
  63--interpolated-path=pathtemplate::
  64        To support virtual hosting, an interpolated path template can be
  65        used to dynamically construct alternate paths.  The template
  66        supports %H for the target hostname as supplied by the client but
  67        converted to all lowercase, %CH for the canonical hostname,
  68        %IP for the server's IP address, %P for the port number,
  69        and %D for the absolute path of the named repository.
  70        After interpolation, the path is validated against the directory
  71        whitelist.
  72
  73--export-all::
  74        Allow pulling from all directories that look like GIT repositories
  75        (have the 'objects' and 'refs' subdirectories), even if they
  76        do not have the 'git-daemon-export-ok' file.
  77
  78--inetd::
  79        Have the server run as an inetd service. Implies --syslog.
  80        Incompatible with --port, --listen, --user and --group options.
  81
  82--listen=host_or_ipaddr::
  83        Listen on an a specific IP address or hostname.  IP addresses can
  84        be either an IPv4 address or an IPV6 address if supported.  If IPv6
  85        is not supported, then --listen=hostname is also not supported and
  86        --listen must be given an IPv4 address.
  87        Incompatible with '--inetd' option.
  88
  89--port=n::
  90        Listen on an alternative port.  Incompatible with '--inetd' option.
  91
  92--init-timeout::
  93        Timeout between the moment the connection is established and the
  94        client request is received (typically a rather low value, since
  95        that should be basically immediate).
  96
  97--timeout::
  98        Timeout for specific client sub-requests. This includes the time
  99        it takes for the server to process the sub-request and time spent
 100        waiting for next client's request.
 101
 102--syslog::
 103        Log to syslog instead of stderr. Note that this option does not imply
 104        --verbose, thus by default only error conditions will be logged.
 105
 106--user-path::
 107--user-path=path::
 108        Allow ~user notation to be used in requests.  When
 109        specified with no parameter, requests to
 110        git://host/~alice/foo is taken as a request to access
 111        'foo' repository in the home directory of user `alice`.
 112        If `--user-path=path` is specified, the same request is
 113        taken as a request to access `path/foo` repository in
 114        the home directory of user `alice`.
 115
 116--verbose::
 117        Log details about the incoming connections and requested files.
 118
 119--reuseaddr::
 120        Use SO_REUSEADDR when binding the listening socket.
 121        This allows the server to restart without waiting for
 122        old connections to time out.
 123
 124--detach::
 125        Detach from the shell. Implies --syslog.
 126
 127--pid-file=file::
 128        Save the process id in 'file'.  Ignored when the daemon
 129        is run under `--inetd`.
 130
 131--user=user::
 132--group=group::
 133        Change daemon's uid and gid before entering the service loop.
 134        When only `--user` is given without `--group`, the
 135        primary group ID for the user is used.  The values of
 136        the option are given to `getpwnam(3)` and `getgrnam(3)`
 137        and numeric IDs are not supported.
 138+
 139Giving these options is an error when used with `--inetd`; use
 140the facility of inet daemon to achieve the same before spawning
 141`git-daemon` if needed.
 142
 143--enable=service::
 144--disable=service::
 145        Enable/disable the service site-wide per default.  Note
 146        that a service disabled site-wide can still be enabled
 147        per repository if it is marked overridable and the
 148        repository enables the service with an configuration
 149        item.
 150
 151--allow-override=service::
 152--forbid-override=service::
 153        Allow/forbid overriding the site-wide default with per
 154        repository configuration.  By default, all the services
 155        are overridable.
 156
 157<directory>::
 158        A directory to add to the whitelist of allowed directories. Unless
 159        --strict-paths is specified this will also include subdirectories
 160        of each named directory.
 161
 162SERVICES
 163--------
 164
 165These services can be globally enabled/disabled using the
 166command line options of this command.  If a finer-grained
 167control is desired (e.g. to allow `git-archive` to be run
 168against only in a few selected repositories the daemon serves),
 169the per-repository configuration file can be used to enable or
 170disable them.
 171
 172upload-pack::
 173        This serves `git-fetch-pack` and `git-ls-remote`
 174        clients.  It is enabled by default, but a repository can
 175        disable it by setting `daemon.uploadpack` configuration
 176        item to `false`.
 177
 178upload-archive::
 179        This serves `git-archive --remote`.  It is disabled by
 180        default, but a repository can enable it by setting
 181        `daemon.uploadarch` configuration item to `true`.
 182
 183receive-pack::
 184        This serves `git-send-pack` clients, allowing anonymous
 185        push.  It is disabled by default, as there is _no_
 186        authentication in the protocol (in other words, anybody
 187        can push anything into the repository, including removal
 188        of refs).  This is solely meant for a closed LAN setting
 189        where everybody is friendly.  This service can be
 190        enabled by `daemon.receivepack` configuration item to
 191        `true`.
 192
 193EXAMPLES
 194--------
 195We assume the following in /etc/services::
 196+
 197------------
 198$ grep 9418 /etc/services
 199git             9418/tcp                # Git Version Control System
 200------------
 201
 202git-daemon as inetd server::
 203        To set up `git-daemon` as an inetd service that handles any
 204        repository under the whitelisted set of directories, /pub/foo
 205        and /pub/bar, place an entry like the following into
 206        /etc/inetd all on one line:
 207+
 208------------------------------------------------
 209        git stream tcp nowait nobody  /usr/bin/git-daemon
 210                git-daemon --inetd --verbose --export-all
 211                /pub/foo /pub/bar
 212------------------------------------------------
 213
 214
 215git-daemon as inetd server for virtual hosts::
 216        To set up `git-daemon` as an inetd service that handles
 217        repositories for different virtual hosts, `www.example.com`
 218        and `www.example.org`, place an entry like the following into
 219        `/etc/inetd` all on one line:
 220+
 221------------------------------------------------
 222        git stream tcp nowait nobody /usr/bin/git-daemon
 223                git-daemon --inetd --verbose --export-all
 224                --interpolated-path=/pub/%H%D
 225                /pub/www.example.org/software
 226                /pub/www.example.com/software
 227                /software
 228------------------------------------------------
 229+
 230In this example, the root-level directory `/pub` will contain
 231a subdirectory for each virtual host name supported.
 232Further, both hosts advertise repositories simply as
 233`git://www.example.com/software/repo.git`.  For pre-1.4.0
 234clients, a symlink from `/software` into the appropriate
 235default repository could be made as well.
 236
 237
 238git-daemon as regular daemon for virtual hosts::
 239        To set up `git-daemon` as a regular, non-inetd service that
 240        handles repositories for multiple virtual hosts based on
 241        their IP addresses, start the daemon like this:
 242+
 243------------------------------------------------
 244        git-daemon --verbose --export-all
 245                --interpolated-path=/pub/%IP/%D
 246                /pub/192.168.1.200/software
 247                /pub/10.10.220.23/software
 248------------------------------------------------
 249+
 250In this example, the root-level directory `/pub` will contain
 251a subdirectory for each virtual host IP address supported.
 252Repositories can still be accessed by hostname though, assuming
 253they correspond to these IP addresses.
 254
 255selectively enable/disable services per repository::
 256        To enable `git-archive --remote` and disable `git-fetch` against
 257        a repository, have the following in the configuration file in the
 258        repository (that is the file 'config' next to 'HEAD', 'refs' and
 259        'objects').
 260+
 261----------------------------------------------------------------
 262        [daemon]
 263                uploadpack = false
 264                uploadarch = true
 265----------------------------------------------------------------
