============== |
|
|
|
NAME |
|
---- |
|
gitweb.conf - Gitweb (Git web interface) configuration file |
|
|
|
SYNOPSIS |
|
-------- |
|
/etc/gitweb.conf, /etc/gitweb-common.conf, $GITWEBDIR/gitweb_config.perl |
|
|
|
DESCRIPTION |
|
----------- |
|
|
|
The gitweb CGI script for viewing Git repositories over the web uses a |
|
perl script fragment as its configuration file. You can set variables |
|
using "`our $variable = value`"; text from a "#" character until the |
|
end of a line is ignored. See *perlsyn*(1) for details. |
|
|
|
An example: |
|
|
|
------------------------------------------------ |
|
# gitweb configuration file for http://git.example.org |
|
# |
|
our $projectroot = "/srv/git"; # FHS recommendation |
|
our $site_name = 'Example.org >> Repos'; |
|
------------------------------------------------ |
|
|
|
|
|
The configuration file is used to override the default settings that |
|
were built into gitweb at the time the 'gitweb.cgi' script was generated. |
|
|
|
While one could just alter the configuration settings in the gitweb |
|
CGI itself, those changes would be lost upon upgrade. Configuration |
|
settings might also be placed into a file in the same directory as the |
|
CGI script with the default name 'gitweb_config.perl' -- allowing |
|
one to have multiple gitweb instances with different configurations by |
|
the use of symlinks. |
|
|
|
Note that some configuration can be controlled on per-repository rather than |
|
gitweb-wide basis: see "Per-repository gitweb configuration" subsection on |
|
linkgit:gitweb[1] manpage. |
|
|
|
|
|
DISCUSSION |
|
---------- |
|
Gitweb reads configuration data from the following sources in the |
|
following order: |
|
|
|
* built-in values (some set during build stage), |
|
|
|
* common system-wide configuration file (defaults to |
|
`/etc/gitweb-common.conf`), |
|
|
|
* either per-instance configuration file (defaults to 'gitweb_config.perl' |
|
in the same directory as the installed gitweb), or if it does not exists |
|
then fallback system-wide configuration file (defaults to `/etc/gitweb.conf`). |
|
|
|
Values obtained in later configuration files override values obtained earlier |
|
in the above sequence. |
|
|
|
Locations of the common system-wide configuration file, the fallback |
|
system-wide configuration file and the per-instance configuration file |
|
are defined at compile time using build-time Makefile configuration |
|
variables, respectively `GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` |
|
and `GITWEB_CONFIG`. |
|
|
|
You can also override locations of gitweb configuration files during |
|
runtime by setting the following environment variables: |
|
`GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` and `GITWEB_CONFIG` |
|
to a non-empty value. |
|
|
|
|
|
The syntax of the configuration files is that of Perl, since these files are |
|
handled by sourcing them as fragments of Perl code (the language that |
|
gitweb itself is written in). Variables are typically set using the |
|
`our` qualifier (as in "`our $variable = <value>;`") to avoid syntax |
|
errors if a new version of gitweb no longer uses a variable and therefore |
|
stops declaring it. |
|
|
|
You can include other configuration file using read_config_file() |
|
subroutine. For example, one might want to put gitweb configuration |
|
related to access control for viewing repositories via Gitolite (one |
|
of Git repository management tools) in a separate file, e.g. in |
|
`/etc/gitweb-gitolite.conf`. To include it, put |
|
|
|
-------------------------------------------------- |
|
read_config_file("/etc/gitweb-gitolite.conf"); |
|
-------------------------------------------------- |
|
|
|
somewhere in gitweb configuration file used, e.g. in per-installation |
|
gitweb configuration file. Note that read_config_file() checks itself |
|
that the file it reads exists, and does nothing if it is not found. |
|
It also handles errors in included file. |
|
|
|
|
|
The default configuration with no configuration file at all may work |
|
perfectly well for some installations. Still, a configuration file is |
|
useful for customizing or tweaking the behavior of gitweb in many ways, and |
|
some optional features will not be present unless explicitly enabled using |
|
the configurable `%features` variable (see also "Configuring gitweb |
|
features" section below). |
|
|
|
|
|
CONFIGURATION VARIABLES |
|
----------------------- |
|
Some configuration variables have their default values (embedded in the CGI |
|
script) set during building gitweb -- if that is the case, this fact is put |
|
in their description. See gitweb's 'INSTALL' file for instructions on building |
|
and installing gitweb. |
|
|
|
|
|
Location of repositories |
|
~~~~~~~~~~~~~~~~~~~~~~~~ |
|
The configuration variables described below control how gitweb finds |
|
Git repositories, and how repositories are displayed and accessed. |
|
|
|
See also "Repositories" and later subsections in linkgit:gitweb[1] manpage. |
|
|
|
$projectroot:: |
|
Absolute filesystem path which will be prepended to project path; |
|
the path to repository is `$projectroot/$project`. Set to |
|
`$GITWEB_PROJECTROOT` during installation. This variable has to be |
|
set correctly for gitweb to find repositories. |
|
+ |
|
For example, if `$projectroot` is set to "/srv/git" by putting the following |
|
in gitweb config file: |
|
+ |
|
---------------------------------------------------------------------------- |
|
our $projectroot = "/srv/git"; |
|
---------------------------------------------------------------------------- |
|
+ |
|
then |
|
+ |
|
------------------------------------------------ |
|
http://git.example.com/gitweb.cgi?p=foo/bar.git |
|
------------------------------------------------ |
|
+ |
|
and its path_info based equivalent |
|
+ |
|
------------------------------------------------ |
|
http://git.example.com/gitweb.cgi/foo/bar.git |
|
------------------------------------------------ |
|
+ |
|
will map to the path `/srv/git/foo/bar.git` on the filesystem. |
|
|
|
$projects_list:: |
|
Name of a plain text file listing projects, or a name of directory |
|
to be scanned for projects. |
|
+ |
|
Project list files should list one project per line, with each line |
|
having the following format |
|
+ |
|
----------------------------------------------------------------------------- |
|
<URI-encoded filesystem path to repository> SP <URI-encoded repository owner> |
|
----------------------------------------------------------------------------- |
|
+ |
|
The default value of this variable is determined by the `GITWEB_LIST` |
|
makefile variable at installation time. If this variable is empty, gitweb |
|
will fall back to scanning the `$projectroot` directory for repositories. |
|
|
|
$project_maxdepth:: |
|
If `$projects_list` variable is unset, gitweb will recursively |
|
scan filesystem for Git repositories. The `$project_maxdepth` |
|
is used to limit traversing depth, relative to `$projectroot` |
|
(starting point); it means that directories which are further |
|
from `$projectroot` than `$project_maxdepth` will be skipped. |
|
+ |
|
It is purely performance optimization, originally intended for MacOS X, |
|
where recursive directory traversal is slow. Gitweb follows symbolic |
|
links, but it detects cycles, ignoring any duplicate files and directories. |
|
+ |
|
The default value of this variable is determined by the build-time |
|
configuration variable `GITWEB_PROJECT_MAXDEPTH`, which defaults to |
|
2007. |
|
|
|
$export_ok:: |
|
Show repository only if this file exists (in repository). Only |
|
effective if this variable evaluates to true. Can be set when |
|
building gitweb by setting `GITWEB_EXPORT_OK`. This path is |
|
relative to `GIT_DIR`. git-daemon[1] uses 'git-daemon-export-ok', |
|
unless started with `--export-all`. By default this variable is |
|
not set, which means that this feature is turned off. |
|
|
|
$export_auth_hook:: |
|
Function used to determine which repositories should be shown. |
|
This subroutine should take one parameter, the full path to |
|
a project, and if it returns true, that project will be included |
|
in the projects list and can be accessed through gitweb as long |
|
as it fulfills the other requirements described by $export_ok, |
|
$projects_list, and $projects_maxdepth. Example: |
|
+ |
|
---------------------------------------------------------------------------- |
|
our $export_auth_hook = sub { return -e "$_[0]/git-daemon-export-ok"; }; |
|
---------------------------------------------------------------------------- |
|
+ |
|
though the above might be done by using `$export_ok` instead |
|
+ |
|
---------------------------------------------------------------------------- |
|
our $export_ok = "git-daemon-export-ok"; |
|
---------------------------------------------------------------------------- |
|
+ |
|
If not set (default), it means that this feature is disabled. |
|
+ |
|
See also more involved example in "Controlling access to Git repositories" |
|
subsection on linkgit:gitweb[1] manpage. |
|
|
|
$strict_export:: |
|
Only allow viewing of repositories also shown on the overview page. |
|
This for example makes `$export_ok` file decide if repository is |
|
available and not only if it is shown. If `$projects_list` points to |
|
file with list of project, only those repositories listed would be |
|
available for gitweb. Can be set during building gitweb via |
|
`GITWEB_STRICT_EXPORT`. By default this variable is not set, which |
|
means that you can directly access those repositories that are hidden |
|
from projects list page (e.g. the are not listed in the $projects_list |
|
file). |
|
|
|
|
|
Finding files |
|
~~~~~~~~~~~~~ |
|
The following configuration variables tell gitweb where to find files. |
|
The values of these variables are paths on the filesystem. |
|
|
|
$GIT:: |
|
Core git executable to use. By default set to `$GIT_BINDIR/git`, which |
|
in turn is by default set to `$(bindir)/git`. If you use Git installed |
|
from a binary package, you should usually set this to "/usr/bin/git". |
|
This can just be "git" if your web server has a sensible PATH; from |
|
security point of view it is better to use absolute path to git binary. |
|
If you have multiple Git versions installed it can be used to choose |
|
which one to use. Must be (correctly) set for gitweb to be able to |
|
work. |
|
|
|
$mimetypes_file:: |
|
File to use for (filename extension based) guessing of MIME types before |
|
trying `/etc/mime.types`. *NOTE* that this path, if relative, is taken |
|
as relative to the current Git repository, not to CGI script. If unset, |
|
only `/etc/mime.types` is used (if present on filesystem). If no mimetypes |
|
file is found, mimetype guessing based on extension of file is disabled. |
|
Unset by default. |
|
|
|
$highlight_bin:: |
|
Path to the highlight executable to use (it must be the one from |
|
http://www.andre-simon.de[] due to assumptions about parameters and output). |
|
By default set to 'highlight'; set it to full path to highlight |
|
executable if it is not installed on your web server's PATH. |
|
Note that 'highlight' feature must be set for gitweb to actually |
|
use syntax highlighting. |
|
+ |
|
*NOTE*: for a file to be highlighted, its syntax type must be detected |
|
and that syntax must be supported by "highlight". The default syntax |
|
detection is minimal, and there are many supported syntax types with no |
|
detection by default. There are three options for adding syntax |
|
detection. The first and second priority are `%highlight_basename` and |
|
`%highlight_ext`, which detect based on basename (the full filename, for |
|
example "Makefile") and extension (for example "sh"). The keys of these |
|
hashes are the basename and extension, respectively, and the value for a |
|
given key is the name of the syntax to be passed via `--syntax <syntax>` |
|
to "highlight". The last priority is the "highlight" configuration of |
|
`Shebang` regular expressions to detect the language based on the first |
|
line in the file, (for example, matching the line "#!/bin/bash"). See |
|
the highlight documentation and the default config at |
|
/etc/highlight/filetypes.conf for more details. |
|
+ |
|
For example if repositories you are hosting use "phtml" extension for |
|
PHP files, and you want to have correct syntax-highlighting for those |
|
files, you can add the following to gitweb configuration: |
|
+ |
|
--------------------------------------------------------- |
|
our %highlight_ext; |
|
$highlight_ext{'phtml'} = 'php'; |
|
--------------------------------------------------------- |
|
|
|
|
|
Links and their targets |
|
~~~~~~~~~~~~~~~~~~~~~~~ |
|
The configuration variables described below configure some of gitweb links: |
|
their target and their look (text or image), and where to find page |
|
prerequisites (stylesheet, favicon, images, scripts). Usually they are left |
|
at their default values, with the possible exception of `@stylesheets` |
|
variable. |
|
|
|
@stylesheets:: |
|
List of URIs of stylesheets (relative to the base URI of a page). You |
|
might specify more than one stylesheet, for example to use "gitweb.css" |
|
as base with site specific modifications in a separate stylesheet |
|
to make it easier to upgrade gitweb. For example, you can add |
|
a `site` stylesheet by putting |
|
+ |
|
---------------------------------------------------------------------------- |
|
push @stylesheets, "gitweb-site.css"; |
|
---------------------------------------------------------------------------- |
|
+ |
|
in the gitweb config file. Those values that are relative paths are |
|
relative to base URI of gitweb. |
|
+ |
|
This list should contain the URI of gitweb's standard stylesheet. The default |
|
URI of gitweb stylesheet can be set at build time using the `GITWEB_CSS` |
|
makefile variable. Its default value is `static/gitweb.css` |
|
(or `static/gitweb.min.css` if the `CSSMIN` variable is defined, |
|
i.e. if CSS minifier is used during build). |
|
+ |
|
*Note*: there is also a legacy `$stylesheet` configuration variable, which was |
|
used by older gitweb. If `$stylesheet` variable is defined, only CSS stylesheet |
|
given by this variable is used by gitweb. |
|
|
|
$logo:: |
|
Points to the location where you put 'git-logo.png' on your web |
|
server, or to be more the generic URI of logo, 72x27 size). This image |
|
is displayed in the top right corner of each gitweb page and used as |
|
a logo for the Atom feed. Relative to the base URI of gitweb (as a path). |
|
Can be adjusted when building gitweb using `GITWEB_LOGO` variable |
|
By default set to `static/git-logo.png`. |
|
|
|
$favicon:: |
|
Points to the location where you put 'git-favicon.png' on your web |
|
server, or to be more the generic URI of favicon, which will be served |
|
as "image/png" type. Web browsers that support favicons (website icons) |
|
may display them in the browser's URL bar and next to the site name in |
|
bookmarks. Relative to the base URI of gitweb. Can be adjusted at |
|
build time using `GITWEB_FAVICON` variable. |
|
By default set to `static/git-favicon.png`. |
|
|
|
$javascript:: |
|
Points to the location where you put 'gitweb.js' on your web server, |
|
or to be more generic the URI of JavaScript code used by gitweb. |
|
Relative to the base URI of gitweb. Can be set at build time using |
|
the `GITWEB_JS` build-time configuration variable. |
|
+ |
|
The default value is either `static/gitweb.js`, or `static/gitweb.min.js` if |
|
the `JSMIN` build variable was defined, i.e. if JavaScript minifier was used |
|
at build time. *Note* that this single file is generated from multiple |
|
individual JavaScript "modules". |
|
|
|
$home_link:: |
|
Target of the home link on the top of all pages (the first part of view |
|
"breadcrumbs"). By default it is set to the absolute URI of a current page |
|
(to the value of `$my_uri` variable, or to "/" if `$my_uri` is undefined |
|
or is an empty string). |
|
|
|
$home_link_str:: |
|
Label for the "home link" at the top of all pages, leading to `$home_link` |
|
(usually the main gitweb page, which contains the projects list). It is |
|
used as the first component of gitweb's "breadcrumb trail": |
|
`<home link> / <project> / <action>`. Can be set at build time using |
|
the `GITWEB_HOME_LINK_STR` variable. By default it is set to "projects", |
|
as this link leads to the list of projects. Another popular choice is to |
|
set it to the name of site. Note that it is treated as raw HTML so it |
|
should not be set from untrusted sources. |
|
|
|
@extra_breadcrumbs:: |
|
Additional links to be added to the start of the breadcrumb trail before |
|
the home link, to pages that are logically "above" the gitweb projects |
|
list, such as the organization and department which host the gitweb |
|
server. Each element of the list is a reference to an array, in which |
|
element 0 is the link text (equivalent to `$home_link_str`) and element |
|
1 is the target URL (equivalent to `$home_link`). |
|
+ |
|
For example, the following setting produces a breadcrumb trail like |
|
"home / dev / projects / ..." where "projects" is the home link. |
|
+ |
|
---------------------------------------------------------------------------- |
|
our @extra_breadcrumbs = ( |
|
[ 'home' => 'https://www.example.org/' ], |
|
[ 'dev' => 'https://dev.example.org/' ], |
|
); |
|
---------------------------------------------------------------------------- |
|
|
|
$logo_url:: |
|
$logo_label:: |
|
URI and label (title) for the Git logo link (or your site logo, |
|
if you chose to use different logo image). By default, these both |
|
refer to Git homepage, https://git-scm.com[]; in the past, they pointed |
|
to Git documentation at https://www.kernel.org[]. |
|
|
|
|
|
Changing gitweb's look |
|
~~~~~~~~~~~~~~~~~~~~~~ |
|
You can adjust how pages generated by gitweb look using the variables described |
|
below. You can change the site name, add common headers and footers for all |
|
pages, and add a description of this gitweb installation on its main page |
|
(which is the projects list page), etc. |
|
|
|
$site_name:: |
|
Name of your site or organization, to appear in page titles. Set it |
|
to something descriptive for clearer bookmarks etc. If this variable |
|
is not set or is, then gitweb uses the value of the `SERVER_NAME` |
|
`CGI` environment variable, setting site name to "$SERVER_NAME Git", |
|
or "Untitled Git" if this variable is not set (e.g. if running gitweb |
|
as standalone script). |
|
+ |
|
Can be set using the `GITWEB_SITENAME` at build time. Unset by default. |
|
|
|
$site_html_head_string:: |
|
HTML snippet to be included in the <head> section of each page. |
|
Can be set using `GITWEB_SITE_HTML_HEAD_STRING` at build time. |
|
No default value. |
|
|
|
$site_header:: |
|
Name of a file with HTML to be included at the top of each page. |
|
Relative to the directory containing the 'gitweb.cgi' script. |
|
Can be set using `GITWEB_SITE_HEADER` at build time. No default |
|
value. |
|
|
|
$site_footer:: |
|
Name of a file with HTML to be included at the bottom of each page. |
|
Relative to the directory containing the 'gitweb.cgi' script. |
|
Can be set using `GITWEB_SITE_FOOTER` at build time. No default |
|
value. |
|
|
|
$home_text:: |
|
Name of a HTML file which, if it exists, is included on the |
|
gitweb projects overview page ("projects_list" view). Relative to |
|
the directory containing the gitweb.cgi script. Default value |
|
can be adjusted during build time using `GITWEB_HOMETEXT` variable. |
|
By default set to 'indextext.html'. |
|
|
|
$projects_list_description_width:: |
|
The width (in characters) of the "Description" column of the projects list. |
|
Longer descriptions will be truncated (trying to cut at word boundary); |
|
the full description is available in the 'title' attribute (usually shown on |
|
mouseover). The default is 25, which might be too small if you |
|
use long project descriptions. |
|
|
|
$default_projects_order:: |
|
Default value of ordering of projects on projects list page, which |
|
means the ordering used if you don't explicitly sort projects list |
|
(if there is no "o" CGI query parameter in the URL). Valid values |
|
are "none" (unsorted), "project" (projects are by project name, |
|
i.e. path to repository relative to `$projectroot`), "descr" |
|
(project description), "owner", and "age" (by date of most current |
|
commit). |
|
+ |
|
Default value is "project". Unknown value means unsorted. |
|
|
|
|
|
Changing gitweb's behavior |
|
~~~~~~~~~~~~~~~~~~~~~~~~~~ |
|
These configuration variables control _internal_ gitweb behavior. |
|
|
|
$default_blob_plain_mimetype:: |
|
Default mimetype for the blob_plain (raw) view, if mimetype checking |
|
doesn't result in some other type; by default "text/plain". |
|
Gitweb guesses mimetype of a file to display based on extension |
|
of its filename, using `$mimetypes_file` (if set and file exists) |
|
and `/etc/mime.types` files (see *mime.types*(5) manpage; only |
|
filename extension rules are supported by gitweb). |
|
|
|
$default_text_plain_charset:: |
|
Default charset for text files. If this is not set, the web server |
|
configuration will be used. Unset by default. |
|
|
|
$fallback_encoding:: |
|
Gitweb assumes this charset when a line contains non-UTF-8 characters. |
|
The fallback decoding is used without error checking, so it can be even |
|
"utf-8". The value must be a valid encoding; see the *Encoding::Supported*(3pm) |
|
man page for a list. The default is "latin1", aka. "iso-8859-1". |
|
|
|
@diff_opts:: |
|
Rename detection options for git-diff and git-diff-tree. The default is |
|
(\'-M'); set it to (\'-C') or (\'-C', \'-C') to also detect copies, |
|
or set it to () i.e. empty list if you don't want to have renames |
|
detection. |
|
+ |
|
*Note* that rename and especially copy detection can be quite |
|
CPU-intensive. Note also that non Git tools can have problems with |
|
patches generated with options mentioned above, especially when they |
|
involve file copies (\'-C') or criss-cross renames (\'-B'). |
|
|
|
|
|
Some optional features and policies |
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ |
|
Most of features are configured via `%feature` hash; however some of extra |
|
gitweb features can be turned on and configured using variables described |
|
below. This list beside configuration variables that control how gitweb |
|
looks does contain variables configuring administrative side of gitweb |
|
(e.g. cross-site scripting prevention; admittedly this as side effect |
|
affects how "summary" pages look like, or load limiting). |
|
|
|
@git_base_url_list:: |
|
List of Git base URLs. These URLs are used to generate URLs |
|
describing from where to fetch a project, which are shown on |
|
project summary page. The full fetch URL is "`$git_base_url/$project`", |
|
for each element of this list. You can set up multiple base URLs |
|
(for example one for `git://` protocol, and one for `http://` |
|
protocol). |
|
+ |
|
Note that per repository configuration can be set in `$GIT_DIR/cloneurl` |
|
file, or as values of multi-value `gitweb.url` configuration variable in |
|
project config. Per-repository configuration takes precedence over value |
|
composed from `@git_base_url_list` elements and project name. |
|
+ |
|
You can setup one single value (single entry/item in this list) at build |
|
time by setting the `GITWEB_BASE_URL` build-time configuration variable. |
|
By default it is set to (), i.e. an empty list. This means that gitweb |
|
would not try to create project URL (to fetch) from project name. |
|
|
|
$projects_list_group_categories:: |
|
Whether to enable the grouping of projects by category on the project |
|
list page. The category of a project is determined by the |
|
`$GIT_DIR/category` file or the `gitweb.category` variable in each |
|
repository's configuration. Disabled by default (set to 0). |
|
|
|
$project_list_default_category:: |
|
Default category for projects for which none is specified. If this is |
|
set to the empty string, such projects will remain uncategorized and |
|
listed at the top, above categorized projects. Used only if project |
|
categories are enabled, which means if `$projects_list_group_categories` |
|
is true. By default set to "" (empty string). |
|
|
|
$prevent_xss:: |
|
If true, some gitweb features are disabled to prevent content in |
|
repositories from launching cross-site scripting (XSS) attacks. Set this |
|
to true if you don't trust the content of your repositories. |
|
False by default (set to 0). |
|
|
|
$maxload:: |
|
Used to set the maximum load that we will still respond to gitweb queries. |
|
If the server load exceeds this value then gitweb will return |
|
"503 Service Unavailable" error. The server load is taken to be 0 |
|
if gitweb cannot determine its value. Currently it works only on Linux, |
|
where it uses `/proc/loadavg`; the load there is the number of active |
|
tasks on the system -- processes that are actually running -- averaged |
|
over the last minute. |
|
+ |
|
Set `$maxload` to undefined value (`undef`) to turn this feature off. |
|
The default value is 300. |
|
|
|
$omit_age_column:: |
|
If true, omit the column with date of the most current commit on the |
|
projects list page. It can save a bit of I/O and a fork per repository. |
|
|
|
$omit_owner:: |
|
If true prevents displaying information about repository owner. |
|
|
|
$per_request_config:: |
|
If this is set to code reference, it will be run once for each request. |
|
You can set parts of configuration that change per session this way. |
|
For example, one might use the following code in a gitweb configuration |
|
file |
|
+ |
|
-------------------------------------------------------------------------------- |
|
our $per_request_config = sub { |
|
$ENV{GL_USER} = $cgi->remote_user || "gitweb"; |
|
}; |
|
-------------------------------------------------------------------------------- |
|
+ |
|
If `$per_request_config` is not a code reference, it is interpreted as boolean |
|
value. If it is true gitweb will process config files once per request, |
|
and if it is false gitweb will process config files only once, each time it |
|
is executed. True by default (set to 1). |
|
+ |
|
*NOTE*: `$my_url`, `$my_uri`, and `$base_url` are overwritten with their default |
|
values before every request, so if you want to change them, be sure to set |
|
this variable to true or a code reference effecting the desired changes. |
|
+ |
|
This variable matters only when using persistent web environments that |
|
serve multiple requests using single gitweb instance, like mod_perl, |
|
FastCGI or Plackup. |
|
|
|
|
|
Other variables |
|
~~~~~~~~~~~~~~~ |
|
Usually you should not need to change (adjust) any of configuration |
|
variables described below; they should be automatically set by gitweb to |
|
correct value. |
|
|
|
|
|
$version:: |
|
Gitweb version, set automatically when creating gitweb.cgi from |
|
gitweb.perl. You might want to modify it if you are running modified |
|
gitweb, for example |
|
+ |
|
--------------------------------------------------- |
|
our $version .= " with caching"; |
|
--------------------------------------------------- |
|
+ |
|
if you run modified version of gitweb with caching support. This variable |
|
is purely informational, used e.g. in the "generator" meta header in HTML |
|
header. |
|
|
|
$my_url:: |
|
$my_uri:: |
|
Full URL and absolute URL of the gitweb script; |
|
in earlier versions of gitweb you might have need to set those |
|
variables, but now there should be no need to do it. See |
|
`$per_request_config` if you need to set them still. |
|
|
|
$base_url:: |
|
Base URL for relative URLs in pages generated by gitweb, |
|
(e.g. `$logo`, `$favicon`, `@stylesheets` if they are relative URLs), |
|
needed and used '<base href="$base_url">' only for URLs with nonempty |
|
PATH_INFO. Usually gitweb sets its value correctly, |
|
and there is no need to set this variable, e.g. to $my_uri or "/". |
|
See `$per_request_config` if you need to override it anyway. |
|
|
|
|
|
CONFIGURING GITWEB FEATURES |
|
--------------------------- |
|
Many gitweb features can be enabled (or disabled) and configured using the |
|
`%feature` hash. Names of gitweb features are keys of this hash. |
|
|
|
Each `%feature` hash element is a hash reference and has the following |
|
structure: |
|
---------------------------------------------------------------------- |
|
"<feature_name>" => { |
|
"sub" => <feature-sub (subroutine)>, |
|
"override" => <allow-override (boolean)>, |
|
"default" => [ <options>... ] |
|
}, |
|
---------------------------------------------------------------------- |
|
Some features cannot be overridden per project. For those |
|
features the structure of appropriate `%feature` hash element has a simpler |
|
form: |
|
---------------------------------------------------------------------- |
|
"<feature_name>" => { |
|
"override" => 0, |
|
"default" => [ <options>... ] |
|
}, |
|
---------------------------------------------------------------------- |
|
As one can see it lacks the \'sub' element. |
|
|
|
The meaning of each part of feature configuration is described |
|
below: |
|
|
|
default:: |
|
List (array reference) of feature parameters (if there are any), |
|
used also to toggle (enable or disable) given feature. |
|
+ |
|
Note that it is currently *always* an array reference, even if |
|
feature doesn't accept any configuration parameters, and \'default' |
|
is used only to turn it on or off. In such case you turn feature on |
|
by setting this element to `[1]`, and torn it off by setting it to |
|
`[0]`. See also the passage about the "blame" feature in the "Examples" |
|
section. |
|
+ |
|
To disable features that accept parameters (are configurable), you |
|
need to set this element to empty list i.e. `[]`. |
|
|
|
override:: |
|
If this field has a true value then the given feature is |
|
overridable, which means that it can be configured |
|
(or enabled/disabled) on a per-repository basis. |
|
+ |
|
Usually given "<feature>" is configurable via the `gitweb.<feature>` |
|
config variable in the per-repository Git configuration file. |
|
+ |
|
*Note* that no feature is overridable by default. |
|
|
|
sub:: |
|
Internal detail of implementation. What is important is that |
|
if this field is not present then per-repository override for |
|
given feature is not supported. |
|
+ |
|
You wouldn't need to ever change it in gitweb config file. |
|
|
|
|
|
Features in `%feature` |
|
~~~~~~~~~~~~~~~~~~~~~~ |
|
The gitweb features that are configurable via `%feature` hash are listed |
|
below. This should be a complete list, but ultimately the authoritative |
|
and complete list is in gitweb.cgi source code, with features described |
|
in the comments. |
|
|
|
blame:: |
|
Enable the "blame" and "blame_incremental" blob views, showing for |
|
each line the last commit that modified it; see linkgit:git-blame[1]. |
|
This can be very CPU-intensive and is therefore disabled by default. |
|
+ |
|
This feature can be configured on a per-repository basis via |
|
repository's `gitweb.blame` configuration variable (boolean). |
|
|
|
snapshot:: |
|
Enable and configure the "snapshot" action, which allows user to |
|
download a compressed archive of any tree or commit, as produced |
|
by linkgit:git-archive[1] and possibly additionally compressed. |
|
This can potentially generate high traffic if you have large project. |
|
+ |
|
The value of \'default' is a list of names of snapshot formats, |
|
defined in `%known_snapshot_formats` hash, that you wish to offer. |
|
Supported formats include "tgz", "tbz2", "txz" (gzip/bzip2/xz |
|
compressed tar archive) and "zip"; please consult gitweb sources for |
|
a definitive list. By default only "tgz" is offered. |
|
+ |
|
This feature can be configured on a per-repository basis via |
|
repository's `gitweb.snapshot` configuration variable, which contains |
|
a comma separated list of formats or "none" to disable snapshots. |
|
Unknown values are ignored. |
|
|
|
grep:: |
|
Enable grep search, which lists the files in currently selected |
|
tree (directory) containing the given string; see linkgit:git-grep[1]. |
|
This can be potentially CPU-intensive, of course. Enabled by default. |
|
+ |
|
This feature can be configured on a per-repository basis via |
|
repository's `gitweb.grep` configuration variable (boolean). |
|
|
|
pickaxe:: |
|
Enable the so called pickaxe search, which will list the commits |
|
that introduced or removed a given string in a file. This can be |
|
practical and quite faster alternative to "blame" action, but it is |
|
still potentially CPU-intensive. Enabled by default. |
|
+ |
|
The pickaxe search is described in linkgit:git-log[1] (the |
|
description of `-S<string>` option, which refers to pickaxe entry in |
|
linkgit:gitdiffcore[7] for more details). |
|
+ |
|
This feature can be configured on a per-repository basis by setting |
|
repository's `gitweb.pickaxe` configuration variable (boolean). |
|
|
|
show-sizes:: |
|
Enable showing size of blobs (ordinary files) in a "tree" view, in a |
|
separate column, similar to what `ls -l` does; see description of |
|
`-l` option in linkgit:git-ls-tree[1] manpage. This costs a bit of |
|
I/O. Enabled by default. |
|
+ |
|
This feature can be configured on a per-repository basis via |
|
repository's `gitweb.showSizes` configuration variable (boolean). |
|
|
|
patches:: |
|
Enable and configure "patches" view, which displays list of commits in email |
|
(plain text) output format; see also linkgit:git-format-patch[1]. |
|
The value is the maximum number of patches in a patchset generated |
|
in "patches" view. Set the 'default' field to a list containing single |
|
item of or to an empty list to disable patch view, or to a list |
|
containing a single negative number to remove any limit. |
|
Default value is 16. |
|
+ |
|
This feature can be configured on a per-repository basis via |
|
repository's `gitweb.patches` configuration variable (integer). |
|
|
|
avatar:: |
|
Avatar support. When this feature is enabled, views such as |
|
"shortlog" or "commit" will display an avatar associated with |
|
the email of each committer and author. |
|
+ |
|
Currently available providers are *"gravatar"* and *"picon"*. |
|
Only one provider at a time can be selected ('default' is one element list). |
|
If an unknown provider is specified, the feature is disabled. |
|
*Note* that some providers might require extra Perl packages to be |
|
installed; see `gitweb/INSTALL` for more details. |
|
+ |
|
This feature can be configured on a per-repository basis via |
|
repository's `gitweb.avatar` configuration variable. |
|
+ |
|
See also `%avatar_size` with pixel sizes for icons and avatars |
|
("default" is used for one-line like "log" and "shortlog", "double" |
|
is used for two-line like "commit", "commitdiff" or "tag"). If the |
|
default font sizes or lineheights are changed (e.g. via adding extra |
|
CSS stylesheet in `@stylesheets`), it may be appropriate to change |
|
these values. |
|
|
|
email-privacy:: |
|
Redact e-mail addresses from the generated HTML, etc. content. |
|
This obscures e-mail addresses retrieved from the author/committer |
|
and comment sections of the Git log. |
|
It is meant to hinder web crawlers that harvest and abuse addresses. |
|
Such crawlers may not respect robots.txt. |
|
Note that users and user tools also see the addresses as redacted. |
|
If Gitweb is not the final step in a workflow then subsequent steps |
|
may misbehave because of the redacted information they receive. |
|
Disabled by default. |
|
|
|
highlight:: |
|
Server-side syntax highlight support in "blob" view. It requires |
|
`$highlight_bin` program to be available (see the description of |
|
this variable in the "Configuration variables" section above), |
|
and therefore is disabled by default. |
|
+ |
|
This feature can be configured on a per-repository basis via |
|
repository's `gitweb.highlight` configuration variable (boolean). |
|
|
|
remote_heads:: |
|
Enable displaying remote heads (remote-tracking branches) in the "heads" |
|
list. In most cases the list of remote-tracking branches is an |
|
unnecessary internal private detail, and this feature is therefore |
|
disabled by default. linkgit:git-instaweb[1], which is usually used |
|
to browse local repositories, enables and uses this feature. |
|
+ |
|
This feature can be configured on a per-repository basis via |
|
repository's `gitweb.remote_heads` configuration variable (boolean). |
|
|
|
|
|
The remaining features cannot be overridden on a per project basis. |
|
|
|
search:: |
|
Enable text search, which will list the commits which match author, |
|
committer or commit text to a given string; see the description of |
|
`--author`, `--committer` and `--grep` options in linkgit:git-log[1] |
|
manpage. Enabled by default. |
|
+ |
|
Project specific override is not supported. |
|
|
|
forks:: |
|
If this feature is enabled, gitweb considers projects in |
|
subdirectories of project root (basename) to be forks of existing |
|
projects. For each project +$projname.git+, projects in the |
|
+$projname/+ directory and its subdirectories will not be |
|
shown in the main projects list. Instead, a \'+' mark is shown |
|
next to `$projname`, which links to a "forks" view that lists all |
|
the forks (all projects in `$projname/` subdirectory). Additionally |
|
a "forks" view for a project is linked from project summary page. |
|
+ |
|
If the project list is taken from a file (+$projects_list+ points to a |
|
file), forks are only recognized if they are listed after the main project |
|
in that file. |
|
+ |
|
Project specific override is not supported. |
|
|
|
actions:: |
|
Insert custom links to the action bar of all project pages. This |
|
allows you to link to third-party scripts integrating into gitweb. |
|
+ |
|
The "default" value consists of a list of triplets in the form |
|
`("<label>", "<link>", "<position>")` where "position" is the label |
|
after which to insert the link, "link" is a format string where `%n` |
|
expands to the project name, `%f` to the project path within the |
|
filesystem (i.e. "$projectroot/$project"), `%h` to the current hash |
|
(\'h' gitweb parameter) and `%b` to the current hash base |
|
(\'hb' gitweb parameter); `%%` expands to \'%'. |
|
+ |
|
For example, at the time this page was written, the http://repo.or.cz[] |
|
Git hosting site set it to the following to enable graphical log |
|
(using the third party tool *git-browser*): |
|
+ |
|
---------------------------------------------------------------------- |
|
$feature{'actions'}{'default'} = |
|
[ ('graphiclog', '/git-browser/by-commit.html?r=%n', 'summary')]; |
|
---------------------------------------------------------------------- |
|
+ |
|
This adds a link titled "graphiclog" after the "summary" link, leading to |
|
`git-browser` script, passing `r=<project>` as a query parameter. |
|
+ |
|
Project specific override is not supported. |
|
|
|
timed:: |
|
Enable displaying how much time and how many Git commands it took to |
|
generate and display each page in the page footer (at the bottom of |
|
page). For example the footer might contain: "This page took 6.53325 |
|
seconds and 13 Git commands to generate." Disabled by default. |
|
+ |
|
Project specific override is not supported. |
|
|
|
javascript-timezone:: |
|
Enable and configure the ability to change a common time zone for dates |
|
in gitweb output via JavaScript. Dates in gitweb output include |
|
authordate and committerdate in "commit", "commitdiff" and "log" |
|
views, and taggerdate in "tag" view. Enabled by default. |
|
+ |
|
The value is a list of three values: a default time zone (for if the client |
|
hasn't selected some other time zone and saved it in a cookie), a name of cookie |
|
where to store selected time zone, and a CSS class used to mark up |
|
dates for manipulation. If you want to turn this feature off, set "default" |
|
to empty list: `[]`. |
|
+ |
|
Typical gitweb config files will only change starting (default) time zone, |
|
and leave other elements at their default values: |
|
+ |
|
--------------------------------------------------------------------------- |
|
$feature{'javascript-timezone'}{'default'}[0] = "utc"; |
|
--------------------------------------------------------------------------- |
|
+ |
|
The example configuration presented here is guaranteed to be backwards |
|
and forward compatible. |
|
+ |
|
Time zone values can be "local" (for local time zone that browser uses), "utc" |
|
(what gitweb uses when JavaScript or this feature is disabled), or numerical |
|
time zones in the form of "+/-HHMM", such as "+0200". |
|
+ |
|
Project specific override is not supported. |
|
|
|
extra-branch-refs:: |
|
List of additional directories under "refs" which are going to |
|
be used as branch refs. For example if you have a gerrit setup |
|
where all branches under refs/heads/ are official, |
|
push-after-review ones and branches under refs/sandbox/, |
|
refs/wip and refs/other are user ones where permissions are |
|
much wider, then you might want to set this variable as |
|
follows: |
|
+ |
|
-------------------------------------------------------------------------------- |
|
$feature{'extra-branch-refs'}{'default'} = |
|
['sandbox', 'wip', 'other']; |
|
-------------------------------------------------------------------------------- |
|
+ |
|
This feature can be configured on per-repository basis after setting |
|
$feature{'extra-branch-refs'}{'override'} to true, via repository's |
|
`gitweb.extraBranchRefs` configuration variable, which contains a |
|
space separated list of refs. An example: |
|
+ |
|
-------------------------------------------------------------------------------- |
|
[gitweb] |
|
extraBranchRefs = sandbox wip other |
|
-------------------------------------------------------------------------------- |
|
+ |
|
The gitweb.extraBranchRefs is actually a multi-valued configuration |
|
variable, so following example is also correct and the result is the |
|
same as of the snippet above: |
|
+ |
|
-------------------------------------------------------------------------------- |
|
[gitweb] |
|
extraBranchRefs = sandbox |
|
extraBranchRefs = wip other |
|
-------------------------------------------------------------------------------- |
|
+ |
|
It is an error to specify a ref that does not pass "git check-ref-format" |
|
scrutiny. Duplicated values are filtered. |
|
|
|
|
|
EXAMPLES |
|
-------- |
|
|
|
To enable blame, pickaxe search, and snapshot support (allowing "tar.gz" and |
|
"zip" snapshots), 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*(1) to run at level 6 by |
|
adding the following lines to your gitweb configuration file: |
|
|
|
$known_snapshot_formats{'zip'}{'disabled'} = 1; |
|
$known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6']; |
|
|
|
BUGS |
|
---- |
|
Debugging would be easier if the fallback configuration file |
|
(`/etc/gitweb.conf`) and environment variable to override its location |
|
('GITWEB_CONFIG_SYSTEM') had names reflecting their "fallback" role. |
|
The current names are kept to avoid breaking working setups. |
|
|
|
ENVIRONMENT |
|
----------- |
|
The location of per-instance and system-wide configuration files can be |
|
overridden using the following environment variables: |
|
|
|
GITWEB_CONFIG:: |
|
Sets location of per-instance configuration file. |
|
GITWEB_CONFIG_SYSTEM:: |
|
Sets location of fallback system-wide configuration file. |
|
This file is read only if per-instance one does not exist. |
|
GITWEB_CONFIG_COMMON:: |
|
Sets location of common system-wide configuration file. |
|
|
|
|
|
FILES |
|
----- |
|
gitweb_config.perl:: |
|
This is default name of per-instance configuration file. The |
|
format of this file is described above. |
|
/etc/gitweb.conf:: |
|
This is default name of fallback system-wide configuration |
|
file. This file is used only if per-instance configuration |
|
variable is not found. |
|
/etc/gitweb-common.conf:: |
|
This is default name of common system-wide configuration |
|
file. |
