NAME¶
gitweb - Git web interface (web frontend to Git repositories)SYNOPSIS¶
To get started with gitweb, run git-instaweb(1) from a Git repository. This would configure and start your web server, and run web browser pointing to gitweb.DESCRIPTION¶
Gitweb provides a web interface to Git repositories. Its features include:•Viewing multiple Git repositories with common
root.
•Browsing every revision of the repository.
•Viewing the contents of files in the repository
at any revision.
•Viewing the revision log of branches, history of
files and directories, see what was changed when, by who.
•Viewing the blame/annotation details of any file
(if enabled).
•Generating RSS and Atom feeds of commits, for any
branch. The feeds are auto-discoverable in modern web browsers.
•Viewing everything that was changed in a
revision, and step through revisions one at a time, viewing the history of the
repository.
•Finding commits which commit messages matches
given search term.
See http://git.kernel.org/?p=git/git.git;a=tree;f=gitweb or
http://repo.or.cz/w/git.git/tree/HEAD:/gitweb/ for gitweb source code,
browsed using gitweb itself.
CONFIGURATION¶
Various aspects of gitweb’s behavior can be controlled through the configuration file gitweb_config.perl or /etc/gitweb.conf. See the gitweb.conf(5) for details.Repositories¶
Gitweb can show information from one or more Git repositories. These repositories have to be all on local filesystem, and have to share common repository root, i.e. be all under a single parent repository (but see also "Advanced web server setup" section, "Webserver configuration with multiple projects' root" subsection).our $projectroot = '/path/to/parent/directory';
Projects list file format¶
Instead of having gitweb find repositories by scanning filesystem starting from $projectroot, you can provide a pre-generated list of visible projects by setting $projects_list to point to a plain text file with a list of projects (with some additional info). This file uses the following format:•One record (for project / repository) per line;
does not support line continuation (newline escaping).
•Leading and trailing whitespace are
ignored.
•Whitespace separated fields; any run of
whitespace can be used as field separator (rules for Perl’s "
split(" ", $line)").
•Fields use modified URI encoding, defined in RFC
3986, section 2.1 (Percent-Encoding), or rather "Query string
encoding" (see
http://en.wikipedia.org/wiki/Query_string#URL_encoding), the difference
being that SP (" ") can be encoded as "+" (and therefore
"+" has to be also percent-encoded).
Reserved characters are: "%" (used for encoding), "+" (can
be used to encode SPACE), all whitespace characters as defined in Perl,
including SP, TAB and LF, (used to separate fields in a record).
•Currently recognized fields are:
<repository path>
You can generate the projects list index file using the project_index action
(the TXT link on projects list page) directly from gitweb; see also
"Generating projects list using gitweb" section below.
Example contents:
path to repository GIT_DIR, relative to
$projectroot
<repository owner>
displayed as repository owner, preferably full name, or
email, or both
foo.git Joe+R+Hacker+<joe@example.com> foo/bar.git O+W+Ner+<owner@example.org>
Generating projects list using gitweb¶
We assume that GITWEB_CONFIG has its default Makefile value, namely gitweb_config.perl. Put the following in gitweb_make_index.perl file:read_config_file("gitweb_config.perl"); $projects_list = $projectroot;
#!/bin/sh export GITWEB_CONFIG="gitweb_make_index.perl" export GATEWAY_INTERFACE="CGI/1.1" export HTTP_ACCEPT="*/*" export REQUEST_METHOD="GET" export QUERY_STRING="a=project_index" perl -- /var/www/cgi-bin/gitweb.cgi
Controlling access to Git repositories¶
By default all Git repositories under $projectroot are visible and available to gitweb. You can however configure how gitweb controls access to repositories.•As described in "Projects list file
format" section, you can control which projects are visible by
selectively including repositories in projects list file, and setting
$projects_list gitweb configuration variable to point to it. With
$strict_export set, projects list file can be used to control which
repositories are available as well.
•You can configure gitweb to only list and allow
viewing of the explicitly exported repositories, via $export_ok
variable in gitweb config file; see gitweb.conf(5) manpage. If it
evaluates to true, gitweb shows repositories only if this file named by
$export_ok exists in its object database (if directory has the magic
file named $export_ok).
For example git-daemon(1) by default (unless --export-all option
is used) allows pulling only for those repositories that have
git-daemon-export-ok file. Adding
makes gitweb show and allow access only to those repositories that can be
fetched from via git:// protocol.
our $export_ok = "git-daemon-export-ok";
•Finally, it is possible to specify an arbitrary
perl subroutine that will be called for each repository to determine if it can
be exported. The subroutine receives an absolute path to the project
(repository) as its only parameter (i.e. "$projectroot/$project").
For example, if you use mod_perl to run the script, and have dumb HTTP protocol
authentication configured for your repositories, you can use the following
hook to allow access only if the user is authorized to read the files:
$export_auth_hook = sub { use Apache2::SubRequest (); use Apache2::Const -compile => qw(HTTP_OK); my $path = "$_[0]/HEAD"; my $r = Apache2::RequestUtil->request; my $sub = $r->lookup_file($path); return $sub->filename eq $path && $sub->status == Apache2::Const::HTTP_OK; };
Per-repository gitweb configuration¶
You can configure individual repositories shown in gitweb by creating file in the GIT_DIR of Git repository, or by setting some repo configuration variable (in GIT_DIR/config, see git-config(1)). You can use the following files in repository: README.htmlA html file (HTML fragment) which is included on the
gitweb project "summary" page inside <div> block
element. You can use it for longer description of a project, to provide links
(for example to project’s homepage), etc. This is recognized only if
XSS prevention is off ( $prevent_xss is false, see
gitweb.conf(5)); a way to include a README safely when XSS prevention
is on may be worked out in the future.
description (or gitweb.description)
Short (shortened to
$projects_list_description_width in the projects list page, which is 25
characters by default; see gitweb.conf(5)) single line description of a
project (of a repository). Plain text file; HTML will be escaped. By default
set to
from the template during repository creation, usually installed in
/usr/share/git-core/templates/. You can use the
gitweb.description repo configuration variable, but the file takes
precedence.
category (or gitweb.category)
Unnamed repository; edit this file to name it for gitweb.
Singe line category of a project, used to group projects
if $projects_list_group_categories is enabled. By default (file and
configuration variable absent), uncategorized projects are put in the
$project_list_default_category category. You can use the
gitweb.category repo configuration variable, but the file takes
precedence.
The configuration variables $projects_list_group_categories and
$project_list_default_category are described in
gitweb.conf(5)
cloneurl (or multiple-valued gitweb.url)
File with repository URL (used for clone and fetch), one
per line. Displayed in the project summary page. You can use multiple-valued
gitweb.url repository configuration variable for that, but the file
takes precedence.
This is per-repository enhancement / version of global prefix-based
@git_base_url_list gitweb configuration variable (see
gitweb.conf(5)).
gitweb.owner
You can use the gitweb.owner repository
configuration variable to set repository’s owner. It is displayed in
the project list and summary page.
If it’s not set, filesystem directory’s owner is used (via GECOS
field, i.e. real name field from getpwuid(3)) if $projects_list
is unset (gitweb scans $projectroot for repositories); if
$projects_list points to file with list of repositories, then project
owner defaults to value from this file for given repository.

list, and descriptions. See also "Configuring gitweb features"
section in gitweb.conf(5)
ACTIONS, AND URLS¶
Gitweb can use path_info (component) based URLs, or it can pass all necessary information via query parameters. The typical gitweb URLs are broken down in to five components:.../gitweb.cgi/<repo>/<action>/<revision>:/<path>?<arguments>
The repository the action will be performed on.
All actions except for those that list all available projects, in whatever form,
require this parameter.
action
The action that will be run. Defaults to
projects_list if repo is not set, and to summary
otherwise.
revision
Revision shown. Defaults to HEAD.
path
The path within the <repository> that the action is
performed on, for those actions that require it.
arguments
Any arguments that control the behaviour of the
action.
Some actions require or allow to specify two revisions, and sometimes even two
pathnames. In most general form such path_info (component) based gitweb URL
looks like this:
.../gitweb.cgi/<repo>/<action>/<revision_from>:/<path_from>..<revision_to>:/<path_to>?<arguments>
$feature{'blame'}{'default'} = [1];
Actions:¶
The standard actions are: project_listLists the available Git repositories. This is the default
command if no repository is specified in the URL.
summary
Displays summary about given repository. This is the
default command if no action is specified in URL, and only repository is
specified.
heads, remotes
Lists all local or all remote-tracking branches in given
repository.
The latter is not available by default, unless configured.
tags
List all tags (lightweight and annotated) in given
repository.
blob, tree
Shows the files and directories in a given repository
path, at given revision. This is default command if no action is specified in
the URL, and path is given.
blob_plain
Returns the raw data for the file in given repository, at
given path and revision. Links to this action are marked raw.
blobdiff
Shows the difference between two revisions of the same
file.
blame, blame_incremental
Shows the blame (also called annotation) information for
a file. On a per line basis it shows the revision in which that line was last
changed and the user that committed the change. The incremental version (which
if configured is used automatically when JavaScript is enabled) uses Ajax to
incrementally add blame info to the contents of given file.
This action is disabled by default for performance reasons.
commit, commitdiff
Shows information about a specific commit in a
repository. The commit view shows information about commit in more
detail, the commitdiff action shows changeset for given commit.
patch
Returns the commit in plain text mail format, suitable
for applying with git-am(1).
tag
Display specific annotated tag (tag object).
log, shortlog
Shows log information (commit message or just commit
subject) for a given branch (starting from given revision).
The shortlog view is more compact; it shows one commit per line.
history
Shows history of the file or directory in a given
repository path, starting from given revision (defaults to HEAD, i.e. default
branch).
This view is similar to shortlog view.
rss, atom
Generates an RSS (or Atom) feed of changes to
repository.
WEBSERVER CONFIGURATION¶
This section explains how to configure some common webservers to run gitweb. In all cases, /path/to/gitweb in the examples is the directory you ran installed gitweb in, and contains gitweb_config.perl. If you’ve configured a web server that isn’t listed here for gitweb, please send in the instructions so they can be included in a future release.Apache as CGI¶
Apache must be configured to support CGI scripts in the directory in which gitweb is installed. Let’s assume that it is /var/www/cgi-bin directory.ScriptAlias /cgi-bin/ "/var/www/cgi-bin/" <Directory "/var/www/cgi-bin"> Options Indexes FollowSymlinks ExecCGI AllowOverride None Order allow,deny Allow from all </Directory>
Apache with mod_perl, via ModPerl::Registry¶
You can use mod_perl with gitweb. You must install Apache::Registry (for mod_perl 1.x) or ModPerl::Registry (for mod_perl 2.x) to enable this support. Assuming that gitweb is installed to /var/www/perl, the following Apache configuration (for mod_perl 2.x) is suitable.Alias /perl "/var/www/perl" <Directory "/var/www/perl"> SetHandler perl-script PerlResponseHandler ModPerl::Registry PerlOptions +ParseHeaders Options Indexes FollowSymlinks +ExecCGI AllowOverride None Order allow,deny Allow from all </Directory>
Apache with FastCGI¶
Gitweb works with Apache and FastCGI. First you need to rename, copy or symlink gitweb.cgi to gitweb.fcgi. Let’s assume that gitweb is installed in /usr/share/gitweb directory. The following Apache configuration is suitable (UNTESTED!)FastCgiServer /usr/share/gitweb/gitweb.cgi ScriptAlias /gitweb /usr/share/gitweb/gitweb.cgi Alias /gitweb/static /usr/share/gitweb/static <Directory /usr/share/gitweb/static> SetHandler default-handler </Directory>
ADVANCED WEB SERVER SETUP¶
All of those examples use request rewriting, and need mod_rewrite (or equivalent; examples below are written for Apache).Single URL for gitweb and for fetching¶
If you want to have one URL for both gitweb and your http:// repositories, you can configure Apache like this:<VirtualHost *:80> ServerName git.example.org DocumentRoot /pub/git SetEnv GITWEB_CONFIG /etc/gitweb.conf # turning on mod rewrite RewriteEngine on # make the front page an internal rewrite to the gitweb script RewriteRule ^/$ /cgi-bin/gitweb.cgi # make access for "dumb clients" work RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \ /cgi-bin/gitweb.cgi%{REQUEST_URI} [L,PT] </VirtualHost>
@stylesheets = ("/some/absolute/path/gitweb.css"); $my_uri = "/"; $home_link = "/"; $per_request_config = 1;
Webserver configuration with multiple projects' root¶
If you want to use gitweb with several project roots you can edit your Apache virtual host and gitweb configuration files in the following way. The virtual host configuration (in Apache configuration file) should look like this:<VirtualHost *:80> ServerName git.example.org DocumentRoot /pub/git SetEnv GITWEB_CONFIG /etc/gitweb.conf # turning on mod rewrite RewriteEngine on # make the front page an internal rewrite to the gitweb script RewriteRule ^/$ /cgi-bin/gitweb.cgi [QSA,L,PT] # look for a public_git folder in unix users' home # http://git.example.org/~<user>/ RewriteRule ^/\~([^\/]+)(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \ [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT] # http://git.example.org/+<user>/ #RewriteRule ^/\+([^\/]+)(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \ [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT] # http://git.example.org/user/<user>/ #RewriteRule ^/user/([^\/]+)/(gitweb.cgi)?$ /cgi-bin/gitweb.cgi \ [QSA,E=GITWEB_PROJECTROOT:/home/$1/public_git/,L,PT] # defined list of project roots RewriteRule ^/scm(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \ [QSA,E=GITWEB_PROJECTROOT:/pub/scm/,L,PT] RewriteRule ^/var(/|/gitweb.cgi)?$ /cgi-bin/gitweb.cgi \ [QSA,E=GITWEB_PROJECTROOT:/var/git/,L,PT] # make access for "dumb clients" work RewriteRule ^/(.*\.git/(?!/?(HEAD|info|objects|refs)).*)?$ \ /cgi-bin/gitweb.cgi%{REQUEST_URI} [L,PT] </VirtualHost>
$projectroot = $ENV{'GITWEB_PROJECTROOT'} || "/pub/git";
PATH_INFO usage¶
If you enable PATH_INFO usage in gitweb by putting$feature{'pathinfo'}{'default'} = [1];
<VirtualHost *:80> ServerAlias git.example.com DocumentRoot /var/www/gitweb <Directory /var/www/gitweb> Options ExecCGI AddHandler cgi-script cgi DirectoryIndex gitweb.cgi RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^.* /gitweb.cgi/$0 [L,PT] </Directory> </VirtualHost>
<VirtualHost *:80> ServerAlias git.example.com DocumentRoot /var/www/gitweb AliasMatch ^(/.*?)(\.git)(/.*)?$ /pub/git$1$3 <Directory /var/www/gitweb> Options ExecCGI AddHandler cgi-script cgi DirectoryIndex gitweb.cgi RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^.* /gitweb.cgi/$0 [L,PT] </Directory> </VirtualHost>
