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::
|
|
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 --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'. 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 an 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.
|
|
|
|
<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.uploadarchive` 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-daemon
|
|
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-daemon
|
|
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
|
|
uploadarchive = true
|
|
----------------------------------------------------------------
