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 --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. |
|
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. |
