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://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 linkgit: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(" ", $line)`"). - -* Fields use modified URI encoding, defined in RFC 3986, section 2.1 -(Percent-Encoding), or rather "Query string encoding" (see -https://en.wikipedia.org/wiki/Query_string#URL_encoding[]), the difference -being that SP (" ") can be encoded as "{plus}" (and therefore "{plus}" has to be -also percent-encoded). -+ -Reserved characters are: "%" (used for encoding), "{plus}" (can be used to -encode SPACE), all whitespace characters as defined in Perl, including SP, -TAB and LF, (used to separate fields in a record). - -* Currently recognized fields are: -<repository path>:: - path to repository GIT_DIR, relative to `$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 `$strict_export` configuration variable (see -linkgit:gitweb.conf[5]) to true value you can allow viewing only of -repositories also shown on the overview page (i.e. only projects explicitly -listed in projects list file will be accessible). - - -Generating projects list using gitweb -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ - -We assume that GITWEB_CONFIG has its default Makefile value, namely -'gitweb_config.perl'. Put the following in 'gitweb_make_index.perl' file: ----------------------------------------------------------------------------- -read_config_file("gitweb_config.perl"); -$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 `$export_ok` variable in gitweb config file; see -linkgit:gitweb.conf[5] manpage. If it evaluates to true, gitweb shows -repositories only if this file named by `$export_ok` exists in its object -database (if directory has the magic file named `$export_ok`). -+ -For example linkgit: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 - && $sub->status == Apache2::Const::HTTP_OK; -}; --------------------------------------------------------------------------- - - -Per-repository gitweb configuration -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -You can configure individual repositories shown in gitweb by creating file -in the `GIT_DIR` of Git repository, or by setting some repo configuration -variable (in `GIT_DIR/config`, see linkgit:git-config[1]). - -You can use the following files in repository: - -README.html:: - A html file (HTML fragment) which is included on the gitweb project - "summary" page inside `<div>` block element. You can use it for longer - description of a project, to provide links (for example to project's - homepage), etc. This is recognized only if XSS prevention is off - (`$prevent_xss` is false, see linkgit: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 `$projects_list_description_width` in the projects - list page, which is 25 characters by default; see - linkgit:gitweb.conf[5]) single line description of a project (of a - repository). Plain text file; HTML will be escaped. By default set to -+ -------------------------------------------------------------------------------- -Unnamed repository; edit this file to name it for gitweb. -------------------------------------------------------------------------------- -+ -from the template during repository creation, usually installed in -`/usr/share/git-core/templates/`. You can use the `gitweb.description` repo -configuration variable, but the file takes precedence. - -category (or `gitweb.category`):: - Singe line category of a project, used to group projects if - `$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 -`$project_list_default_category` are described in linkgit:gitweb.conf[5] - -cloneurl (or multiple-valued `gitweb.url`):: - File with repository URL (used for clone and fetch), one per line. - Displayed in the project summary page. You can use multiple-valued - `gitweb.url` repository configuration variable for that, but the file - takes precedence. -+ -This is per-repository enhancement / version of global prefix-based -`@git_base_url_list` gitweb configuration variable (see -linkgit:gitweb.conf[5]). - -gitweb.owner:: - You can use the `gitweb.owner` repository configuration variable to set - repository's owner. It is displayed in the project list and summary - page. -+ -If it's not set, filesystem directory's owner is used (via GECOS field, -i.e. real name field from *getpwuid*(3)) if `$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. - -various `gitweb.*` config variables (in config):: - Read description of `%feature` hash for detailed list, and descriptions. - See also "Configuring gitweb features" section in linkgit: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> ------------------------------------------------------------------------ - -repo:: - 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> ------------------------------------------------------------------------ - - -Each action is implemented as a subroutine, and must be present in %actions -hash. Some actions are disabled by default, and must be turned on via feature -mechanism. For example to enable 'blame' view add the following to gitweb -configuration file: - ------------------------------------------------------------------------ -$feature{'blame'}{'default'} = [1]; ------------------------------------------------------------------------ - - -Actions: -~~~~~~~~ -The standard actions are: - -project_list:: - Lists 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 - linkgit: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> ------------------------------------------------------------------------ - -With that configuration the full path to browse repositories would be: - - http://server/cgi-bin/gitweb.cgi - -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> ------------------------------------------------------------------------ - -With that configuration the full path to browse repositories would be: - - http://server/perl/gitweb.cgi - -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> ------------------------------------------------------------------------ - -With that configuration the full path to browse repositories would be: - - http://server/gitweb - - -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> ------------------------------------------------------------------------ - -The above configuration expects your public repositories to live under -`/pub/git` and will serve them as `http://git.domain.org/dir-under-pub-git`, -both as clonable Git URL and as browseable gitweb interface. If you then -start your linkgit:git-daemon[1] with `--base-path=/pub/git --export-all` -then you can even use the `git://` URL with exactly the same path. - -Setting the environment variable `GITWEB_CONFIG` will tell gitweb to use the -named file (i.e. in this example `/etc/gitweb.conf`) as a configuration for -gitweb. You don't really need it in above example; it is required only if -your configuration file is in different place than built-in (during -compiling gitweb) 'gitweb_config.perl' or `/etc/gitweb.conf`. See -linkgit:gitweb.conf[5] for details, especially information about precedence -rules. - -If you use the rewrite rules from the example you *might* also need -something like the following in your gitweb configuration file -(`/etc/gitweb.conf` following example): ----------------------------------------------------------------------------- -@stylesheets = ("/some/absolute/path/gitweb.css"); -$my_uri = "/"; -$home_link = "/"; -$per_request_config = 1; ----------------------------------------------------------------------------- -Nowadays though gitweb should create HTML base tag when needed (to set base -URI for relative links), so it should work automatically. - - -Webserver configuration with multiple projects' root -~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ -If you want to use gitweb with several project roots you can edit your -Apache virtual host and gitweb configuration files in the following way. - -The virtual host configuration (in Apache configuration file) should look -like this: --------------------------------------------------------------------------- -<VirtualHost *:80> - ServerName git.example.org - DocumentRoot /pub/git - SetEnv GITWEB_CONFIG /etc/gitweb.conf - - # turning on mod rewrite - RewriteEngine on - - # make the front page an internal rewrite to the gitweb script - RewriteRule ^/$ /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> --------------------------------------------------------------------------- - -Here actual project root is passed to gitweb via `GITWEB_PROJECT_ROOT` -environment variable from a web server, so you need to put the following -line in gitweb configuration file (`/etc/gitweb.conf` in above example): --------------------------------------------------------------------------- -$projectroot = $ENV{'GITWEB_PROJECTROOT'} || "/pub/git"; --------------------------------------------------------------------------- -*Note* that this requires to be set for each request, so either -`$per_request_config` must be false, or the above must be put in code -referenced by `$per_request_config`; - -These configurations enable two things. First, each unix user (`<user>`) of -the server will be able to browse through gitweb Git repositories found in -`~/public_git/` with the following url: - - http://git.example.org/~<user>/ - -If you do not want this feature on your server just remove the second -rewrite rule. - -If you already use `mod_userdir` in your virtual host or you don't want to -use the \'~' as first character, just comment or remove the second rewrite -rule, and uncomment one of the following according to what you want. - -Second, repositories found in `/pub/scm/` and `/var/git/` will be accessible -through `http://git.example.org/scm/` and `http://git.example.org/var/`. -You can add as many project roots as you want by adding rewrite rules like -the third and the fourth. - - -PATH_INFO usage -~~~~~~~~~~~~~~~ -If you enable PATH_INFO usage in gitweb by putting ----------------------------------------------------------------------------- -$feature{'pathinfo'}{'default'} = [1]; ----------------------------------------------------------------------------- -in your gitweb configuration file, it is possible to set up your server so -that it consumes and produces URLs in the form - - http://git.example.com/project.git/shortlog/sometag - -i.e. without 'gitweb.cgi' part, by using a configuration such as the -following. This configuration assumes that `/var/www/gitweb` is the -DocumentRoot of your webserver, contains the gitweb.cgi script and -complementary static files (stylesheet, favicon, JavaScript): - ----------------------------------------------------------------------------- -<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/$0 [L,PT] - </Directory> -</VirtualHost> ----------------------------------------------------------------------------- -The rewrite rule guarantees that existing static files will be properly -served, whereas any other URL will be passed to gitweb as PATH_INFO -parameter. - -*Notice* that in this case you don't need special settings for -`@stylesheets`, `$my_uri` and `$home_link`, but you lose "dumb client" -access to your project .git dirs (described in "Single URL for gitweb and -for fetching" section). A possible workaround for the latter is the -following: in your project root dir (e.g. `/pub/git`) have the projects -named *without* a .git extension (e.g. `/pub/git/project` instead of -`/pub/git/project.git`) and configure Apache as follows: ----------------------------------------------------------------------------- -<VirtualHost *:80> - ServerAlias git.example.com - - DocumentRoot /var/www/gitweb - - AliasMatch ^(/.*?)(\.git)(/.*)?$ /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> ----------------------------------------------------------------------------- - -The additional AliasMatch makes it so that - - http://git.example.com/project.git - -will give raw access to the project's Git dir (so that the project can be -cloned), while - - http://git.example.com/project - -will provide human-friendly gitweb access. - -This solution is not 100% bulletproof, in the sense that if some project has -a named ref (branch, tag) starting with `git/`, then paths such as - - http://git.example.com/project/command/abranch..git/abranch - -will fail with a 404 error. - - -BUGS ----- -Please report any bugs or feature requests to git@vger.kernel.org, -putting "gitweb" in the subject of email. - -SEE ALSO --------- -linkgit:gitweb.conf[5], linkgit:git-instaweb[1] - -`gitweb/README`, `gitweb/INSTALL` - -GIT ---- -Part of the linkgit:git[1] suite |
