With Git 3.0 though, Rust will always be enabled. +# +# Building Rust code requires Cargo. +# +# == SHA-1 and SHA-256 defines == +# +# === SHA-1 backend === +# +# ==== Security ==== +# +# Due to the SHAttered (https://shattered.io) attack vector on SHA-1 +# it's strongly recommended to use the sha1collisiondetection +# counter-cryptanalysis library for SHA-1 hashing. +# +# If you know that you can trust the repository contents, or where +# potential SHA-1 attacks are otherwise mitigated the other backends +# listed in "SHA-1 implementations" are faster than +# sha1collisiondetection. +# +# ==== Default SHA-1 backend ==== +# +# If no *_SHA1 backend is picked, the first supported one listed in +# "SHA-1 implementations" will be picked. +# +# ==== Options common to all SHA-1 implementations ==== +# +# Define SHA1_MAX_BLOCK_SIZE to limit the amount of data that will be hashed +# in one call to the platform's SHA1_Update(). e.g. APPLE_COMMON_CRYPTO +# wants 'SHA1_MAX_BLOCK_SIZE=1024L*1024L*1024L' defined. +# +# ==== SHA-1 implementations ==== +# +# Define OPENSSL_SHA1 to link to the SHA-1 routines from the OpenSSL +# library. +# +# Define BLK_SHA1 to make use of optimized C SHA-1 routines bundled +# with git (in the block-sha1/ directory). +# +# Define APPLE_COMMON_CRYPTO_SHA1 to use Apple's CommonCrypto for +# SHA-1. +# +# Define the same Makefile knobs as above, but suffixed with _UNSAFE to +# use the corresponding implementations for unsafe SHA-1 hashing for +# non-cryptographic purposes. +# +# If don't enable any of the *_SHA1 settings in this section, Git will +# default to its built-in sha1collisiondetection library, which is a +# collision-detecting sha1 This is slower, but may detect attempted +# collision attacks. +# +# ==== Options for the sha1collisiondetection library ==== +# +# Define DC_SHA1_EXTERNAL if you want to build / link +# git with the external SHA1 collision-detect library. +# Without this option, i.e. the default behavior is to build git with its +# own built-in code (or submodule). +# +# Define DC_SHA1_SUBMODULE to use the +# sha1collisiondetection shipped as a submodule instead of the +# non-submodule copy in sha1dc/. This is an experimental option used +# by the git project to migrate to using sha1collisiondetection as a +# submodule. +# +# === SHA-256 backend === +# +# ==== Security ==== +# +# Unlike SHA-1 the SHA-256 algorithm does not suffer from any known +# vulnerabilities, so any implementation will do. +# +# ==== SHA-256 implementations ==== +# +# Define OPENSSL_SHA256 to use the SHA-256 routines in OpenSSL. +# +# Define NETTLE_SHA256 to use the SHA-256 routines in libnettle. +# +# Define GCRYPT_SHA256 to use the SHA-256 routines in libgcrypt. +# +# If don't enable any of the *_SHA256 settings in this section, Git +# will default to its built-in sha256 implementation. +# +# == DEVELOPER defines == +# +# Define DEVELOPER to enable more compiler warnings. Compiler version +# and family are auto detected, but could be overridden by defining +# COMPILER_FEATURES (see config.mak.dev). You can still set +# CFLAGS="..." in combination with DEVELOPER enables, whether that's +# for tweaking something unrelated (e.g. optimization level), or for +# selectively overriding something DEVELOPER or one of the DEVOPTS +# (see just below) brings in. +# +# When DEVELOPER is set, DEVOPTS can be used to control compiler +# options. This variable contains keywords separated by +# whitespace. The following keywords are recognized: +# +# no-error: +# +# suppresses the -Werror that implicitly comes with +# DEVELOPER=1.

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_HTML_HEAD_STRING + html snippet to include in the section of each page. [No default] + * 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://andre-simon.de/zip/download.php 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), and gitweb.conf(5) manpage. + +- You can configure gitweb further using the per-instance 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. + + Note that the GITWEB_CONFIG_SYSTEM system-wide configuration file is + only used for instances that lack per-instance configuration file. + You can use GITWEB_CONFIG_COMMON common system-wide configuration + file (normally /etc/gitweb-common.conf) to keep common default + settings that apply to all instances. Settings from per-instance or + system-wide configuration file override those from common system-wide + configuration file. + +- 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.
