GIT web Interface (gitweb) Installation ======================================= First you have to generate gitweb.cgi from gitweb.perl using "make gitweb", then "make install-gitweb" appropriate files (gitweb.cgi, gitweb.js, gitweb.css, git-logo.png and git-favicon.png) to their destination. For example if git was (or is) installed with /usr prefix and gitwebdir is /var/www/cgi-bin, you can do $ make prefix=/usr gitweb ;# as yourself # make gitwebdir=/var/www/cgi-bin install-gitweb ;# as root Alternatively you can use autoconf generated ./configure script to set up path to git binaries (via config.mak.autogen), so you can write instead $ make configure ;# as yourself $ ./configure --prefix=/usr ;# as yourself $ make gitweb ;# as yourself # make gitwebdir=/var/www/cgi-bin \ install-gitweb ;# as root The above example assumes that your web server is configured to run [executable] files in /var/www/cgi-bin/ as server scripts (as CGI scripts). Requirements ------------ - Core git tools - Perl - Perl modules: CGI, Encode, Fcntl, File::Find, File::Basename. - web server The following optional Perl modules are required for extra features - Digest::MD5 - for gravatar support - CGI::Fast and FCGI - for running gitweb as FastCGI script - HTML::TagCloud - for fancy tag cloud in project list view - HTTP::Date or Time::ParseDate - to support If-Modified-Since for feeds Build time configuration ------------------------ See also "How to configure gitweb for your local system" section below. - There are many configuration variables which affect building of gitweb.cgi; see "default configuration for gitweb" section in main (top dir) Makefile, and instructions for building gitweb target. One of the most important is where to find the git wrapper binary. Gitweb tries to find the git wrapper at $(bindir)/git, so you have to set $bindir when building gitweb.cgi, or $prefix from which $bindir is derived. If you build and install gitweb together with the rest of the git suite, there should be no problems. Otherwise, if git was for example installed from a binary package, you have to set $prefix (or $bindir) accordingly. - Another important issue is where are git repositories you want to make available to gitweb. By default gitweb searches for repositories under /pub/git; if you want to have projects somewhere else, like /home/git, use 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. This can be changed (configured) as described in "Gitweb repositories" section below. Note that gitweb deals directly with the object database, and does not need a working directory; the name of the project is the name of its repository object database, usually projectname.git for bare repositories. If you want to provide gitweb access to non-bare (live) repositories, you can make projectname.git a symbolic link under projectroot linking to projectname/.git (but it is just a suggestion). - You can control where gitweb tries to find its main CSS style file, its JavaScript file, its favicon and logo with the GITWEB_CSS, GITWEB_JS GITWEB_FAVICON and GITWEB_LOGO build configuration variables. By default gitweb tries to find them in the same directory as gitweb.cgi script. - You can optionally generate minified versions of gitweb.js and gitweb.css by defining the JSMIN and CSSMIN build configuration variables. By default the non-minified versions will be used. NOTE: if you enable this option, substitute gitweb.min.js and gitweb.min.css for all uses of gitweb.js and gitweb.css in the help files. How to configure gitweb for your local system --------------------------------------------- You can specify the following configuration variables when building GIT: * GIT_BINDIR Points where to find the git executable. You should set it up to the place where the git binary was installed (usually /usr/bin) if you don't install git from sources together with gitweb. [Default: $(bindir)] * GITWEB_SITENAME Shown in the title of all generated pages, defaults to the server name (SERVER_NAME CGI environment variable) if not set. [No default] * GITWEB_PROJECTROOT The root directory for all projects shown by gitweb. Must be set correctly for gitweb to find repositories to display. See also "Gitweb repositories" in the INSTALL file for gitweb. [Default: /pub/git] * GITWEB_PROJECT_MAXDEPTH The filesystem traversing limit for getting the project list; the number is taken as depth relative to the projectroot. It is used when GITWEB_LIST is a directory (or is not set; then project root is used). This is meant to speed up project listing on large work trees by limiting search depth. [Default: 2007] * GITWEB_LIST Points to a directory to scan for projects (defaults to project root if not set / if empty) or to a file with explicit listing of projects (together with projects' ownership). See "Generating projects list using gitweb" in INSTALL file for gitweb to find out how to generate such file from scan of a directory. [No default, which means use root directory for projects] * GITWEB_EXPORT_OK Show repository only if this file exists (in repository). Only effective if this variable evaluates to true. [No default / Not set] * GITWEB_STRICT_EXPORT Only allow viewing of repositories also shown on the overview page. This for example makes GITWEB_EXPORT_OK to decide if repository is available and not only if it is shown. If GITWEB_LIST points to file with list of project, only those repositories listed would be available for gitweb. [No default] * GITWEB_HOMETEXT Points to an .html file which is included on the gitweb project overview page ('projects_list' view), if it exists. Relative to gitweb.cgi script. [Default: indextext.html] * GITWEB_SITE_HEADER Filename of html text to include at top of each page. Relative to gitweb.cgi script. [No default] * GITWEB_SITE_FOOTER Filename of html text to include at bottom of each page. Relative to gitweb.cgi script. [No default] * GITWEB_HOME_LINK_STR String of the home link on top of all pages, leading to $home_link (usually main gitweb page, which means projects list). Used as first part of gitweb view "breadcrumb trail": / / . [Default: projects] * GITWEB_SITENAME Name of your site or organization to appear in page titles. Set it to something descriptive for clearer bookmarks etc. If not set (if empty) gitweb uses "$SERVER_NAME Git", or "Untitled Git" if SERVER_NAME CGI environment variable is not set (e.g. if running gitweb as standalone script). [No default] * GITWEB_BASE_URL Git base URLs used for URL to where fetch project from, i.e. full URL is "$git_base_url/$project". Shown on projects summary page. Repository URL for project can be also configured per repository; this takes precedence over URLs composed from base URL and a project name. Note that you can setup multiple base URLs (for example one for git:// protocol access, another for http:// access) from the gitweb config file. [No default] * GITWEB_CSS Points to the location where you put gitweb.css on your web server (or to be more generic, the URI of gitweb stylesheet). Relative to the base URI of gitweb. Note that you can setup multiple stylesheets from the gitweb config file. [Default: static/gitweb.css (or static/gitweb.min.css if the CSSMIN variable is defined / CSS minifier is used)] * GITWEB_JS Points to the location where you put gitweb.js on your web server (or to be more generic URI of JavaScript code used by gitweb). Relative to base URI of gitweb. [Default: static/gitweb.js (or static/gitweb.min.js if JSMIN build variable is defined / JavaScript minifier is used)] * CSSMIN, JSMIN Invocation of a CSS minifier or a JavaScript minifier, respectively, working as a filter (source on standard input, minified result on standard output). If set, it is used to generate a minified version of 'static/gitweb.css' or 'static/gitweb.js', respectively. *Note* that minified files would have *.min.css and *.min.js extension, which is important if you also set GITWEB_CSS and/or GITWEB_JS. [No default] * GITWEB_LOGO Points to the location where you put git-logo.png on your web server (or to be more generic URI of logo, 72x27 size, displayed in top right corner of each gitweb page, and used as logo for Atom feed). Relative to base URI of gitweb. [Default: static/git-logo.png] * GITWEB_FAVICON Points to the location where you put git-favicon.png on your web server (or to be more generic URI of favicon, assumed to be image/png type; web browsers that support favicons (website icons) may display them in the browser's URL bar and next to site name in bookmarks). Relative to base URI of gitweb. [Default: static/git-favicon.png] * GITWEB_CONFIG This Perl file will be loaded using 'do' and can be used to override any of the options above as well as some other options -- see the "Runtime gitweb configuration" section below, and top of 'gitweb.cgi' for their full list and description. If the environment variable GITWEB_CONFIG is set when gitweb.cgi is executed, then the file specified in the environment variable will be loaded instead of the file specified when gitweb.cgi was created. [Default: gitweb_config.perl] * GITWEB_CONFIG_SYSTEM This Perl file will be loaded using 'do' as a fallback if GITWEB_CONFIG does not exist. If the environment variable GITWEB_CONFIG_SYSTEM is set when gitweb.cgi is executed, then the file specified in the environment variable will be loaded instead of the file specified when gitweb.cgi was created. [Default: /etc/gitweb.conf] * HIGHLIGHT_BIN Path to the highlight executable to use (must be the one from http://www.andre-simon.de due to assumptions about parameters and output). Useful if highlight is not installed on your webserver's PATH. [Default: highlight] Build example ~~~~~~~~~~~~~ - To install gitweb to /var/www/cgi-bin/gitweb/, when git wrapper is installed at /usr/local/bin/git, the repositories (projects) we want to display are under /home/local/scm, and you do not use minifiers, you can do make GITWEB_PROJECTROOT="/home/local/scm" \ GITWEB_JS="gitweb/static/gitweb.js" \ GITWEB_CSS="gitweb/static/gitweb.css" \ GITWEB_LOGO="gitweb/static/git-logo.png" \ GITWEB_FAVICON="gitweb/static/git-favicon.png" \ bindir=/usr/local/bin \ gitweb make gitwebdir=/var/www/cgi-bin/gitweb install-gitweb Gitweb config file ------------------ See also "Runtime gitweb configuration" section in README file for gitweb (in gitweb/README). - You can configure gitweb further using the gitweb configuration file; by default this is a file named gitweb_config.perl in the same place as gitweb.cgi script. You can control the default place for the config file using the GITWEB_CONFIG build configuration variable, and you can set it using the GITWEB_CONFIG environment variable. If this file does not exist, gitweb looks for a system-wide configuration file, normally /etc/gitweb.conf. You can change the default using the GITWEB_CONFIG_SYSTEM build configuration variable, and override it through the GITWEB_CONFIG_SYSTEM environment variable. - The gitweb config file is a fragment of perl code. You can set variables using "our $variable = value"; text from "#" character until the end of a line is ignored. See perlsyn(1) for details. See the top of gitweb.perl file for examples of customizable options. Config file example ~~~~~~~~~~~~~~~~~~~ To enable blame, pickaxe search, and snapshot support, while allowing individual projects to turn them off, put the following in your GITWEB_CONFIG file: $feature{'blame'}{'default'} = [1]; $feature{'blame'}{'override'} = 1; $feature{'pickaxe'}{'default'} = [1]; $feature{'pickaxe'}{'override'} = 1; $feature{'snapshot'}{'default'} = ['zip', 'tgz']; $feature{'snapshot'}{'override'} = 1; If you allow overriding for the snapshot feature, you can specify which snapshot formats are globally disabled. You can also add any command line options you want (such as setting the compression level). For instance, you can disable Zip compressed snapshots and set GZip to run at level 6 by adding the following lines to your $GITWEB_CONFIG: $known_snapshot_formats{'zip'}{'disabled'} = 1; $known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6']; Gitweb repositories ------------------- - 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). You can provide a pre-generated list of [visible] repositories, together with information about their owners (the project ownership defaults to the owner of the repository directory otherwise), by setting the GITWEB_LIST build configuration variable (or the $projects_list variable in the gitweb config file) to point to a plain file. Each line of the projects list file should consist of the url-encoded path to the project repository database (relative to projectroot), followed by the url-encoded project owner on the same line (separated by a space). Spaces in both project path and project owner have to be encoded as either '%20' or '+'. Other characters that have to be url-encoded, i.e. replaced by '%' followed by two-digit character number in octal, are: other whitespace characters (because they are field separator in a record), plus sign '+' (because it can be used as replacement for spaces), and percent sign '%' (which is used for encoding / escaping). You can generate the projects list index file using the project_index action (the 'TXT' link on projects list page) directly from gitweb. - By default, even if a project is not visible on projects list page, you can view it nevertheless by hand-crafting a gitweb URL. You can set the GITWEB_STRICT_EXPORT build configuration variable (or the $strict_export variable in the gitweb config file) to only allow viewing of repositories also shown on the overview page. - Alternatively, you can configure gitweb to only list and allow viewing of the explicitly exported repositories, via the GITWEB_EXPORT_OK build configuration variable (or the $export_ok variable in gitweb config file). If it evaluates to true, gitweb shows repositories only if this file exists in its object database (if directory has the magic file named $export_ok). - Finally, it is possible to specify an arbitrary perl subroutine that will be called for each project to determine if it can be exported. The subroutine receives an absolute path to the project as its only parameter. 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; }; 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: $GITWEB_CONFIG = "gitweb_config.perl"; do $GITWEB_CONFIG if -e $GITWEB_CONFIG; $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 Example web server configuration ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ See also "Webserver configuration" section in README file for gitweb (in gitweb/README). - Apache2, gitweb installed as CGI script, under /var/www/cgi-bin/ ScriptAlias /cgi-bin/ "/var/www/cgi-bin/" Options Indexes FollowSymlinks ExecCGI AllowOverride None Order allow,deny Allow from all - Apache2, gitweb installed as mod_perl legacy script, under /var/www/perl/ Alias /perl "/var/www/perl" SetHandler perl-script PerlResponseHandler ModPerl::Registry PerlOptions +ParseHeaders Options Indexes FollowSymlinks +ExecCGI AllowOverride None Order allow,deny Allow from all
