@subsubsection Version Control
|
||||
|
||||
The @code{(gnu services version-control)} module provides the following services:
|
||||
|
||||
@subsubheading Git daemon service
|
||||
|
||||
@deffn {Scheme Procedure} git-daemon-service [#:config (git-daemon-configuration)]
|
||||
|
||||
Return a service that runs @command{git daemon}, a simple TCP server to
|
||||
expose repositiories over the Git protocol for annoymous access.
|
||||
|
||||
The optional @var{config} argument should be a
|
||||
@code{<git-daemon-configuration>} object, by default it allows read-only
|
||||
access to exported@footnote{By creating the magic file
|
||||
"git-daemon-export-ok" in the repository directory.} repositories under
|
||||
@file{/srv/git}.
|
||||
|
||||
@end deffn
|
||||
|
||||
@deftp {Data Type} git-daemon-configuration
|
||||
Data type representing the configuration for @code{git-daemon-service}.
|
||||
|
||||
@table @asis
|
||||
@item @code{package} (default: @var{git})
|
||||
Package object of the Git distributed version control system.
|
||||
|
||||
@item @code{export-all?} (default: @var{#f})
|
||||
Whether to allow access for all Git repositories, even if they do not
|
||||
have the @file{git-daemon-export-ok} file.
|
||||
|
||||
@item @code{base-path} (default: @file{/srv/git})
|
||||
Whether to remap all the path requests as relative to the given path.
|
||||
If you run git daemon with @var{(base-path "/srv/git")} on example.com,
|
||||
then if you later try to pull @code{git://example.com/hello.git}, git
|
||||
daemon will interpret the path as @code{/srv/git/hello.git}.
|
||||
|
||||
@item @code{user-path} (default: @var{#f})
|
||||
Whether to allow @code{~user} notation to be used in requests. When
|
||||
specified with empty string, requests to @code{git://host/~alice/foo} is
|
||||
taken as a request to access @code{foo} repository in the home directory
|
||||
of user @code{alice}. If @var{(user-path "path")} is specified, the
|
||||
same request is taken as a request to access @code{path/foo} repository
|
||||
in the home directory of user @code{alice}.
|
||||
|
||||
@item @code{listen} (default: @var{'()})
|
||||
Whether to listen on specific IP addresses or hostnames, defaults to
|
||||
all.
|
||||
|
||||
@item @code{port} (default: @var{#f})
|
||||
Whether to listen on an alternative port, which defaults to 9418.
|
||||
|
||||
@item @code{whitelist} (default: @var{'()})
|
||||
If not empty, only allow access to this list of directories.
|
||||
|
||||
@item @code{extra-options} (default: @var{'()})
|
||||
Extra options will be passed to @code{git daemon}, please run
|
||||
@command{man git-daemon} for more information.
