Конфигурация (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';

The default value for $projectroot is /pub/git. You can change it during building gitweb via GITWEB_PROJECTROOT build configuration variable.

By default all Git repositories under $projectroot are visible and available to gitweb. The list of projects is generated by default by scanning the $projectroot directory for Git repositories (for object databases to be more exact; gitweb is not interested in a working area, and is best suited to showing "bare" repositories).

The name of the repository in gitweb is the path to its $GIT_DIR (its object database) relative to $projectroot. Therefore the repository $repo can be found at "$projectroot/$repo".

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 https://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> path to repository GIT_DIR, relative to $projectroot

<repository owner> displayed as repository owner, preferably full name, or email, or both

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:

foo.git Joe+R+Hacker+<joe@example.com> foo/bar.git O+W+Ner+<owner@example.org>

By default this file controls only which projects are visible on projects list page (note that entries that do not point to correctly recognized Git repositories won't be displayed by gitweb). Even if a project is not visible on projects list page, you can view it nevertheless by hand-crafting a gitweb URL. By setting $strict_export configuration variable (see gitweb.conf(5)) to true value you can allow viewing only of repositories also shown on the overview page (i.e. only projects explicitly listed in projects list file will be accessible).

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;

Then create the following script to get list of project in the format suitable for GITWEB_LIST build configuration variable (or $projects_list variable in gitweb config):

#!/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

Run this script and save its output to a file. This file could then be used as projects list file, which means that you can set $projects_list to its filename.

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

our $export_ok = "git-daemon-export-ok";

makes gitweb show and allow access only to those repositories that can be fetched from via git:// protocol.

• 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.html A 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

Unnamed repository; edit this file to name it for gitweb.

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) 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.
