The point of these sections is generally to: 1. Give credit where it is due. 2. Give the reader an idea of where to ask questions or file bug reports. But they don't do a good job of either case. For (1), they are out of date and incomplete. A much more accurate answer can be gotten through shortlog or blame. For (2), the correct contact point is generally git@vger, and even if you wanted to cc the contact point, the out-of-date and incomplete fields mean you're likely sending to somebody useless. So let's drop the fields entirely from all manpages except git(1) itself. We already point people to the mailing list for bug reports there, and we can update the Authors section to give credit to the major contributors and point to shortlog and blame for more information. Each page has a "This is part of git" footer, so people can follow that to the main git manpage.

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 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 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 {tilde}user notation to be used in requests. When
|
|
specified with no parameter, requests to
|
|
git://host/{tilde}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.
|
|
|
|
<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.
