Gitweb + tries to find 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 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 search 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. 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 object database, and does not + need 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) + repository, you can make projectname.git 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 favicon and logo with GITWEB_CSS, GITWEB_FAVICON and GITWEB_LOGO + build configuration variables. By default gitweb tries to find them + in the same directory as gitweb.cgi script. + +Build example +~~~~~~~~~~~~~ + +- To install gitweb to /var/www/cgi-bin/gitweb/ when git wrapper + is installed at /usr/local/bin/git and the repositories (projects) + we want to display are under /home/local/scm, you can do + + make GITWEB_PROJECTROOT="/home/local/scm" \ + GITWEB_CSS="/gitweb/gitweb.css" \ + GITWEB_LOGO="/gitweb/git-logo.png" \ + GITWEB_FAVICON="/gitweb/git-favicon.png" \ + bindir=/usr/local/bin \ + gitweb/gitweb.cgi + + cp -fv ~/git/gitweb/gitweb.{cgi,css} \ + ~/git/gitweb/git-{favicon,logo}.png \ + /var/www/cgi-bin/gitweb/ + + +Gitweb config file +------------------ + +See also "Runtime gitweb configuration" section in README file +for gitweb (in gitweb/README). + +- You can configure gitweb further using gitweb configuration file; + by default it is file named gitweb_config.perl in the same place as + gitweb.cgi script. You can control default place for config file + using GITWEB_CONFIG build configuration variable, and you can set it + using GITWEB_CONFIG environmental variable. + +- Gitweb config file is [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'} = ['x-gzip', 'gz', 'gzip']; + $feature{'snapshot'}{'override'} = 1; + + +Gitweb repositories +------------------- + +- By default all git repositories under projectroot are visible and + available to gitweb. 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 pre-generated list of [visible] repositories, + together with information about their owners (the project ownership + is taken from owner of repository directory otherwise), by setting + GITWEB_LIST build configuration variable (or $projects_list variable + in gitweb config file) to point to a plain file. + + Each line of projects list file should consist of url-encoded path + to project repository database (relative to projectroot) separated + by space from url-encoded project owner; spaces in both project path + and project owner have to be encoded as either '%20' or '+'. + + You can generate projects list index file using project_index action + (the 'TXT' link on projects list page) directly from gitweb. + +- By default even if project is not visible on projects list page, you + can view it nevertheless by hand-crafting gitweb URL. You can set + GITWEB_STRICT_EXPORT build configuration variable (or $strict_export + variable in 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 + GITWEB_EXPORT_OK build configuration variable (or $export_ok + variable in gitweb config file). If it evaluates to true, gitweb + show repository only if this file exists in its object database + (if directory has the magic file $export_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 + + +Requirements +------------ + + - Core git tools + - Perl + - Perl modules: CGI, Encode, Fcntl, File::Find, File::Basename. + - web server + + +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/" + + <Directory "/var/www/cgi-bin"> + Options Indexes FollowSymlinks ExecCGI + AllowOverride None + Order allow,deny + Allow from all + </Directory> + +- Apache2, gitweb installed as mod_perl legacy script, + under /var/www/perl/ + + 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> diff --git a/gitweb/README b/gitweb/README new file mode 100644 index 0000000000..e02e90f042 --- /dev/null +++ b/gitweb/README @@ -0,0 +1,82 @@ +GIT web Interface +================= + +The one working on: + http://www.kernel.org/git/ + +From the git version 1.4.0 gitweb is bundled with git. + + +How to configure gitweb for your local system +--------------------------------------------- + +You can specify the following configuration variables when building GIT: + * GITWEB_SITENAME + Shown in the title of all generated pages, defaults to the servers name. + * GITWEB_PROJECTROOT + The root directory for all projects shown by gitweb. + * GITWEB_LIST + points to a directory to scan for projects (defaults to project root) + or to a file for explicit listing of projects. + * GITWEB_HOMETEXT + points to an .html file which is included on the gitweb project + overview page. + * GITWEB_CSS + Points to the location where you put gitweb.css on your web server. + * GITWEB_LOGO + Points to the location where you put git-logo.png on your web server. + * GITWEB_CONFIG + This file will be loaded using 'require' and can be used to override any + of the options above as well as some other options - see the top of + 'gitweb.cgi' for their full list and description.
