DESCRIPTION
A really simple TCP git daemon that normally listens on port
"DEFAULT_GIT_PORT" 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 (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 ls-remote clients, which are invoked from git fetch,
git pull, and git clone.
This is ideally suited for read-only updates, i.e., pulling from git
repositories.
An upload-archive also exists to serve git archive.
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=<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.
--base-path-relaxed
If --base-path is enabled and repo lookup fails, with this option
git daemon will attempt to lookup without prefixing the base path.
This is useful for switching to --base-path usage, while still
allowing the old paths.
--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. Implies --syslog.
Incompatible with --detach, --port, --listen, --user and --group
options.
--listen=<host_or_ipaddr>
Listen on 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. Can be given more than
once. Incompatible with --inetd option.
--port=<n>
Listen on an alternative port. Incompatible with --inetd option.
--init-timeout=<n>
Timeout (in seconds) 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=<n>
Timeout (in seconds) for specific client sub-requests. This
includes the time it takes for the server to process the
sub-request and the time spent waiting for the next client's
request.
--max-connections=<n>
Maximum number of concurrent clients, defaults to 32. Set it to
zero for no limit.
--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. Ignored when the daemon is run under
--inetd.
--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 a configuration item.
--allow-override=<service>, --forbid-override=<service>
Allow/forbid overriding the site-wide default with per repository
configuration. By default, all the services are overridable.
--informative-errors, --no-informative-errors
When informative errors are turned on, git-daemon will report more
verbose errors to the client, differentiating conditions like "no
such repository" from "repository not exported". This is more
convenient for clients, but may leak information about the
existence of unexported repositories. When informative errors are
not enabled, all errors report "access denied" to the client. The
default is --no-informative-errors.
<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
These services can be globally enabled/disabled using the command line
options of this command. If a finer-grained control is desired (e.g. to
allow git archive to be run against only in a few selected repositories
the daemon serves), the per-repository configuration file can be used
to enable or disable them.
upload-pack
This serves git fetch-pack and git ls-remote clients. It is enabled
by default, but a repository can disable it by setting
daemon.uploadpack configuration item to false.
upload-archive
This serves git archive --remote. It is disabled by default, but a
repository can enable it by setting daemon.uploadarch configuration
item to true.
receive-pack
This serves git send-pack clients, allowing anonymous push. It is
disabled by default, as there is no authentication in the protocol
(in other words, anybody can push anything into the repository,
including removal of refs). This is solely meant for a closed LAN
setting where everybody is friendly. This service can be enabled by
daemon.receivepack configuration item to true.
EXAMPLES
We assume the following in /etc/services
$ grep 9418 /etc/services
git 9418/tcp # Git Version Control System
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
git daemon --inetd --verbose --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
git daemon --inetd --verbose --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.
selectively enable/disable services per repository
To enable git archive --remote and disable git fetch against a
repository, have the following in the configuration file in the
repository (that is the file config next to HEAD, refs and
objects).
[daemon]
uploadpack = false
uploadarch = true
ENVIRONMENT
git daemon will set REMOTE_ADDR to the IP address of the client that
connected to it, if the IP address is available. REMOTE_ADDR will be
available in the environment of hooks called when services are
performed.
