4 | NAME | |
5 | ---- | |
2de9b711 | 6 | gitweb.conf - Gitweb (Git web interface) configuration file |
6d3902b0 DN |
7 | |
8 | SYNOPSIS | |
9 | -------- | |
10 | /etc/gitweb.conf, /etc/gitweb-common.conf, $GITWEBDIR/gitweb_config.perl | |
11 | ||
12 | DESCRIPTION | |
13 | ----------- | |
14 | ||
15 | The gitweb CGI script for viewing Git repositories over the web uses a | |
16 | perl script fragment as its configuration file. You can set variables | |
17 | using "`our $variable = value`"; text from a "#" character until the | |
18 | end of a line is ignored. See *perlsyn*(1) for details. | |
19 | ||
20 | An example: | |
21 | ||
9aab3fcf AH |
22 | ------------------------------------------------ |
23 | # gitweb configuration file for http://git.example.org | |
24 | # | |
25 | our $projectroot = "/srv/git"; # FHS recommendation | |
26 | our $site_name = 'Example.org >> Repos'; | |
27 | ------------------------------------------------ | |
6d3902b0 DN |
28 | |
29 | ||
30 | The configuration file is used to override the default settings that | |
31 | were built into gitweb at the time the 'gitweb.cgi' script was generated. | |
32 | ||
33 | While one could just alter the configuration settings in the gitweb | |
34 | CGI itself, those changes would be lost upon upgrade. Configuration | |
35 | settings might also be placed into a file in the same directory as the | |
36 | CGI script with the default name 'gitweb_config.perl' -- allowing | |
37 | one to have multiple gitweb instances with different configurations by | |
38 | the use of symlinks. | |
39 | ||
07ea4df2 JN |
40 | Note that some configuration can be controlled on per-repository rather than |
41 | gitweb-wide basis: see "Per-repository gitweb configuration" subsection on | |
42 | linkgit:gitweb[1] manpage. | |
43 | ||
6d3902b0 DN |
44 | |
45 | DISCUSSION | |
46 | ---------- | |
47 | Gitweb reads configuration data from the following sources in the | |
48 | following order: | |
49 | ||
50 | * built-in values (some set during build stage), | |
51 | ||
52 | * common system-wide configuration file (defaults to | |
68ed71b5 | 53 | `/etc/gitweb-common.conf`), |
6d3902b0 DN |
54 | |
55 | * either per-instance configuration file (defaults to 'gitweb_config.perl' | |
56 | in the same directory as the installed gitweb), or if it does not exists | |
68ed71b5 | 57 | then fallback system-wide configuration file (defaults to `/etc/gitweb.conf`). |
6d3902b0 DN |
58 | |
59 | Values obtained in later configuration files override values obtained earlier | |
60 | in the above sequence. | |
61 | ||
62 | Locations of the common system-wide configuration file, the fallback | |
63 | system-wide configuration file and the per-instance configuration file | |
64 | are defined at compile time using build-time Makefile configuration | |
65 | variables, respectively `GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` | |
66 | and `GITWEB_CONFIG`. | |
67 | ||
68 | You can also override locations of gitweb configuration files during | |
69 | runtime by setting the following environment variables: | |
70 | `GITWEB_CONFIG_COMMON`, `GITWEB_CONFIG_SYSTEM` and `GITWEB_CONFIG` | |
71 | to a non-empty value. | |
72 | ||
73 | ||
74 | The syntax of the configuration files is that of Perl, since these files are | |
75 | handled by sourcing them as fragments of Perl code (the language that | |
76 | gitweb itself is written in). Variables are typically set using the | |
77 | `our` qualifier (as in "`our $variable = <value>;`") to avoid syntax | |
78 | errors if a new version of gitweb no longer uses a variable and therefore | |
79 | stops declaring it. | |
80 | ||
81 | You can include other configuration file using read_config_file() | |
82 | subroutine. For example, one might want to put gitweb configuration | |
83 | related to access control for viewing repositories via Gitolite (one | |
2de9b711 | 84 | of Git repository management tools) in a separate file, e.g. in |
68ed71b5 | 85 | `/etc/gitweb-gitolite.conf`. To include it, put |
6d3902b0 DN |
86 | |
87 | -------------------------------------------------- | |
88 | read_config_file("/etc/gitweb-gitolite.conf"); | |
89 | -------------------------------------------------- | |
90 | ||
91 | somewhere in gitweb configuration file used, e.g. in per-installation | |
92 | gitweb configuration file. Note that read_config_file() checks itself | |
93 | that the file it reads exists, and does nothing if it is not found. | |
94 | It also handles errors in included file. | |
95 | ||
96 | ||
97 | The default configuration with no configuration file at all may work | |
98 | perfectly well for some installations. Still, a configuration file is | |
99 | useful for customizing or tweaking the behavior of gitweb in many ways, and | |
100 | some optional features will not be present unless explicitly enabled using | |
101 | the configurable `%features` variable (see also "Configuring gitweb | |
102 | features" section below). | |
103 | ||
104 | ||
105 | CONFIGURATION VARIABLES | |
106 | ----------------------- | |
107 | Some configuration variables have their default values (embedded in the CGI | |
108 | script) set during building gitweb -- if that is the case, this fact is put | |
109 | in their description. See gitweb's 'INSTALL' file for instructions on building | |
110 | and installing gitweb. | |
111 | ||
112 | ||
113 | Location of repositories | |
114 | ~~~~~~~~~~~~~~~~~~~~~~~~ | |
115 | The configuration variables described below control how gitweb finds | |
2de9b711 | 116 | Git repositories, and how repositories are displayed and accessed. |
6d3902b0 | 117 | |
07ea4df2 JN |
118 | See also "Repositories" and later subsections in linkgit:gitweb[1] manpage. |
119 | ||
6d3902b0 DN |
120 | $projectroot:: |
121 | Absolute filesystem path which will be prepended to project path; | |
122 | the path to repository is `$projectroot/$project`. Set to | |
123 | `$GITWEB_PROJECTROOT` during installation. This variable has to be | |
124 | set correctly for gitweb to find repositories. | |
125 | + | |
126 | For example, if `$projectroot` is set to "/srv/git" by putting the following | |
127 | in gitweb config file: | |
128 | + | |
129 | ---------------------------------------------------------------------------- | |
130 | our $projectroot = "/srv/git"; | |
131 | ---------------------------------------------------------------------------- | |
132 | + | |
133 | then | |
134 | + | |
135 | ------------------------------------------------ | |
136 | http://git.example.com/gitweb.cgi?p=foo/bar.git | |
137 | ------------------------------------------------ | |
138 | + | |
139 | and its path_info based equivalent | |
140 | + | |
141 | ------------------------------------------------ | |
142 | http://git.example.com/gitweb.cgi/foo/bar.git | |
143 | ------------------------------------------------ | |
144 | + | |
68ed71b5 | 145 | will map to the path `/srv/git/foo/bar.git` on the filesystem. |
6d3902b0 DN |
146 | |
147 | $projects_list:: | |
148 | Name of a plain text file listing projects, or a name of directory | |
149 | to be scanned for projects. | |
150 | + | |
151 | Project list files should list one project per line, with each line | |
152 | having the following format | |
153 | + | |
154 | ----------------------------------------------------------------------------- | |
155 | <URI-encoded filesystem path to repository> SP <URI-encoded repository owner> | |
156 | ----------------------------------------------------------------------------- | |
157 | + | |
158 | The default value of this variable is determined by the `GITWEB_LIST` | |
159 | makefile variable at installation time. If this variable is empty, gitweb | |
160 | will fall back to scanning the `$projectroot` directory for repositories. | |
161 | ||
162 | $project_maxdepth:: | |
163 | If `$projects_list` variable is unset, gitweb will recursively | |
2de9b711 | 164 | scan filesystem for Git repositories. The `$project_maxdepth` |
6d3902b0 DN |
165 | is used to limit traversing depth, relative to `$projectroot` |
166 | (starting point); it means that directories which are further | |
167 | from `$projectroot` than `$project_maxdepth` will be skipped. | |
168 | + | |
169 | It is purely performance optimization, originally intended for MacOS X, | |
170 | where recursive directory traversal is slow. Gitweb follows symbolic | |
171 | links, but it detects cycles, ignoring any duplicate files and directories. | |
172 | + | |
173 | The default value of this variable is determined by the build-time | |
174 | configuration variable `GITWEB_PROJECT_MAXDEPTH`, which defaults to | |
175 | 2007. | |
176 | ||
177 | $export_ok:: | |
178 | Show repository only if this file exists (in repository). Only | |
179 | effective if this variable evaluates to true. Can be set when | |
180 | building gitweb by setting `GITWEB_EXPORT_OK`. This path is | |
181 | relative to `GIT_DIR`. git-daemon[1] uses 'git-daemon-export-ok', | |
182 | unless started with `--export-all`. By default this variable is | |
183 | not set, which means that this feature is turned off. | |
184 | ||
185 | $export_auth_hook:: | |
186 | Function used to determine which repositories should be shown. | |
187 | This subroutine should take one parameter, the full path to | |
188 | a project, and if it returns true, that project will be included | |
189 | in the projects list and can be accessed through gitweb as long | |
190 | as it fulfills the other requirements described by $export_ok, | |
191 | $projects_list, and $projects_maxdepth. Example: | |
192 | + | |
193 | ---------------------------------------------------------------------------- | |
194 | our $export_auth_hook = sub { return -e "$_[0]/git-daemon-export-ok"; }; | |
195 | ---------------------------------------------------------------------------- | |
196 | + | |
197 | though the above might be done by using `$export_ok` instead | |
198 | + | |
199 | ---------------------------------------------------------------------------- | |
200 | our $export_ok = "git-daemon-export-ok"; | |
201 | ---------------------------------------------------------------------------- | |
202 | + | |
203 | If not set (default), it means that this feature is disabled. | |
07ea4df2 | 204 | + |
2de9b711 | 205 | See also more involved example in "Controlling access to Git repositories" |
07ea4df2 | 206 | subsection on linkgit:gitweb[1] manpage. |
6d3902b0 DN |
207 | |
208 | $strict_export:: | |
209 | Only allow viewing of repositories also shown on the overview page. | |
f116ee21 DO |
210 | This for example makes `$export_ok` file decide if repository is |
211 | available and not only if it is shown. If `$projects_list` points to | |
6d3902b0 DN |
212 | file with list of project, only those repositories listed would be |
213 | available for gitweb. Can be set during building gitweb via | |
214 | `GITWEB_STRICT_EXPORT`. By default this variable is not set, which | |
215 | means that you can directly access those repositories that are hidden | |
216 | from projects list page (e.g. the are not listed in the $projects_list | |
217 | file). | |
218 | ||
219 | ||
220 | Finding files | |
221 | ~~~~~~~~~~~~~ | |
222 | The following configuration variables tell gitweb where to find files. | |
223 | The values of these variables are paths on the filesystem. | |
224 | ||
225 | $GIT:: | |
226 | Core git executable to use. By default set to `$GIT_BINDIR/git`, which | |
2de9b711 | 227 | in turn is by default set to `$(bindir)/git`. If you use Git installed |
6d3902b0 DN |
228 | from a binary package, you should usually set this to "/usr/bin/git". |
229 | This can just be "git" if your web server has a sensible PATH; from | |
230 | security point of view it is better to use absolute path to git binary. | |
2de9b711 | 231 | If you have multiple Git versions installed it can be used to choose |
6d3902b0 DN |
232 | which one to use. Must be (correctly) set for gitweb to be able to |
233 | work. | |
234 | ||
235 | $mimetypes_file:: | |
236 | File to use for (filename extension based) guessing of MIME types before | |
68ed71b5 | 237 | trying `/etc/mime.types`. *NOTE* that this path, if relative, is taken |
2de9b711 | 238 | as relative to the current Git repository, not to CGI script. If unset, |
68ed71b5 | 239 | only `/etc/mime.types` is used (if present on filesystem). If no mimetypes |
6d3902b0 DN |
240 | file is found, mimetype guessing based on extension of file is disabled. |
241 | Unset by default. | |
242 | ||
243 | $highlight_bin:: | |
244 | Path to the highlight executable to use (it must be the one from | |
245 | http://www.andre-simon.de[] due to assumptions about parameters and output). | |
246 | By default set to 'highlight'; set it to full path to highlight | |
247 | executable if it is not installed on your web server's PATH. | |
248 | Note that 'highlight' feature must be set for gitweb to actually | |
b4ab1980 | 249 | use syntax highlighting. |
6d3902b0 | 250 | + |
779a2066 IK |
251 | *NOTE*: for a file to be highlighted, its syntax type must be detected |
252 | and that syntax must be supported by "highlight". The default syntax | |
253 | detection is minimal, and there are many supported syntax types with no | |
254 | detection by default. There are three options for adding syntax | |
255 | detection. The first and second priority are `%highlight_basename` and | |
256 | `%highlight_ext`, which detect based on basename (the full filename, for | |
257 | example "Makefile") and extension (for example "sh"). The keys of these | |
258 | hashes are the basename and extension, respectively, and the value for a | |
259 | given key is the name of the syntax to be passed via `--syntax <syntax>` | |
260 | to "highlight". The last priority is the "highlight" configuration of | |
261 | `Shebang` regular expressions to detect the language based on the first | |
262 | line in the file, (for example, matching the line "#!/bin/bash"). See | |
263 | the highlight documentation and the default config at | |
264 | /etc/highlight/filetypes.conf for more details. | |
6d3902b0 DN |
265 | + |
266 | For example if repositories you are hosting use "phtml" extension for | |
267 | PHP files, and you want to have correct syntax-highlighting for those | |
268 | files, you can add the following to gitweb configuration: | |
269 | + | |
270 | --------------------------------------------------------- | |
271 | our %highlight_ext; | |
272 | $highlight_ext{'phtml'} = 'php'; | |
273 | --------------------------------------------------------- | |
274 | ||
275 | ||
276 | Links and their targets | |
277 | ~~~~~~~~~~~~~~~~~~~~~~~ | |
278 | The configuration variables described below configure some of gitweb links: | |
279 | their target and their look (text or image), and where to find page | |
280 | prerequisites (stylesheet, favicon, images, scripts). Usually they are left | |
281 | at their default values, with the possible exception of `@stylesheets` | |
282 | variable. | |
283 | ||
284 | @stylesheets:: | |
285 | List of URIs of stylesheets (relative to the base URI of a page). You | |
286 | might specify more than one stylesheet, for example to use "gitweb.css" | |
287 | as base with site specific modifications in a separate stylesheet | |
288 | to make it easier to upgrade gitweb. For example, you can add | |
289 | a `site` stylesheet by putting | |
290 | + | |
291 | ---------------------------------------------------------------------------- | |
292 | push @stylesheets, "gitweb-site.css"; | |
293 | ---------------------------------------------------------------------------- | |
294 | + | |
295 | in the gitweb config file. Those values that are relative paths are | |
296 | relative to base URI of gitweb. | |
297 | + | |
298 | This list should contain the URI of gitweb's standard stylesheet. The default | |
299 | URI of gitweb stylesheet can be set at build time using the `GITWEB_CSS` | |
68ed71b5 CB |
300 | makefile variable. Its default value is `static/gitweb.css` |
301 | (or `static/gitweb.min.css` if the `CSSMIN` variable is defined, | |
6d3902b0 DN |
302 | i.e. if CSS minifier is used during build). |
303 | + | |
304 | *Note*: there is also a legacy `$stylesheet` configuration variable, which was | |
305 | used by older gitweb. If `$stylesheet` variable is defined, only CSS stylesheet | |
306 | given by this variable is used by gitweb. | |
307 | ||
308 | $logo:: | |
309 | Points to the location where you put 'git-logo.png' on your web | |
310 | server, or to be more the generic URI of logo, 72x27 size). This image | |
311 | is displayed in the top right corner of each gitweb page and used as | |
312 | a logo for the Atom feed. Relative to the base URI of gitweb (as a path). | |
313 | Can be adjusted when building gitweb using `GITWEB_LOGO` variable | |
68ed71b5 | 314 | By default set to `static/git-logo.png`. |
6d3902b0 DN |
315 | |
316 | $favicon:: | |
317 | Points to the location where you put 'git-favicon.png' on your web | |
318 | server, or to be more the generic URI of favicon, which will be served | |
319 | as "image/png" type. Web browsers that support favicons (website icons) | |
320 | may display them in the browser's URL bar and next to the site name in | |
321 | bookmarks. Relative to the base URI of gitweb. Can be adjusted at | |
322 | build time using `GITWEB_FAVICON` variable. | |
68ed71b5 | 323 | By default set to `static/git-favicon.png`. |
6d3902b0 DN |
324 | |
325 | $javascript:: | |
326 | Points to the location where you put 'gitweb.js' on your web server, | |
327 | or to be more generic the URI of JavaScript code used by gitweb. | |
328 | Relative to the base URI of gitweb. Can be set at build time using | |
329 | the `GITWEB_JS` build-time configuration variable. | |
330 | + | |
68ed71b5 | 331 | The default value is either `static/gitweb.js`, or `static/gitweb.min.js` if |
6d3902b0 DN |
332 | the `JSMIN` build variable was defined, i.e. if JavaScript minifier was used |
333 | at build time. *Note* that this single file is generated from multiple | |
334 | individual JavaScript "modules". | |
335 | ||
336 | $home_link:: | |
337 | Target of the home link on the top of all pages (the first part of view | |
338 | "breadcrumbs"). By default it is set to the absolute URI of a current page | |
339 | (to the value of `$my_uri` variable, or to "/" if `$my_uri` is undefined | |
340 | or is an empty string). | |
341 | ||
342 | $home_link_str:: | |
343 | Label for the "home link" at the top of all pages, leading to `$home_link` | |
344 | (usually the main gitweb page, which contains the projects list). It is | |
345 | used as the first component of gitweb's "breadcrumb trail": | |
346 | `<home link> / <project> / <action>`. Can be set at build time using | |
347 | the `GITWEB_HOME_LINK_STR` variable. By default it is set to "projects", | |
ad9c2e22 TF |
348 | as this link leads to the list of projects. Another popular choice is to |
349 | set it to the name of site. Note that it is treated as raw HTML so it | |
350 | should not be set from untrusted sources. | |
351 | ||
352 | @extra_breadcrumbs:: | |
353 | Additional links to be added to the start of the breadcrumb trail before | |
354 | the home link, to pages that are logically "above" the gitweb projects | |
355 | list, such as the organization and department which host the gitweb | |
356 | server. Each element of the list is a reference to an array, in which | |
357 | element 0 is the link text (equivalent to `$home_link_str`) and element | |
358 | 1 is the target URL (equivalent to `$home_link`). | |
359 | + | |
360 | For example, the following setting produces a breadcrumb trail like | |
361 | "home / dev / projects / ..." where "projects" is the home link. | |
9aab3fcf | 362 | + |
ad9c2e22 TF |
363 | ---------------------------------------------------------------------------- |
364 | our @extra_breadcrumbs = ( | |
365 | [ 'home' => 'https://www.example.org/' ], | |
366 | [ 'dev' => 'https://dev.example.org/' ], | |
367 | ); | |
368 | ---------------------------------------------------------------------------- | |
6d3902b0 DN |
369 | |
370 | $logo_url:: | |
371 | $logo_label:: | |
372 | URI and label (title) for the Git logo link (or your site logo, | |
373 | if you chose to use different logo image). By default, these both | |
e52a53df JK |
374 | refer to Git homepage, https://git-scm.com[]; in the past, they pointed |
375 | to Git documentation at https://www.kernel.org[]. | |
6d3902b0 DN |
376 | |
377 | ||
378 | Changing gitweb's look | |
379 | ~~~~~~~~~~~~~~~~~~~~~~ | |
380 | You can adjust how pages generated by gitweb look using the variables described | |
381 | below. You can change the site name, add common headers and footers for all | |
382 | pages, and add a description of this gitweb installation on its main page | |
383 | (which is the projects list page), etc. | |
384 | ||
385 | $site_name:: | |
386 | Name of your site or organization, to appear in page titles. Set it | |
387 | to something descriptive for clearer bookmarks etc. If this variable | |
388 | is not set or is, then gitweb uses the value of the `SERVER_NAME` | |
47d81b5c | 389 | `CGI` environment variable, setting site name to "$SERVER_NAME Git", |
6d3902b0 DN |
390 | or "Untitled Git" if this variable is not set (e.g. if running gitweb |
391 | as standalone script). | |
392 | + | |
393 | Can be set using the `GITWEB_SITENAME` at build time. Unset by default. | |
394 | ||
c1355b7f LH |
395 | $site_html_head_string:: |
396 | HTML snippet to be included in the <head> section of each page. | |
397 | Can be set using `GITWEB_SITE_HTML_HEAD_STRING` at build time. | |
398 | No default value. | |
399 | ||
6d3902b0 DN |
400 | $site_header:: |
401 | Name of a file with HTML to be included at the top of each page. | |
402 | Relative to the directory containing the 'gitweb.cgi' script. | |
403 | Can be set using `GITWEB_SITE_HEADER` at build time. No default | |
404 | value. | |
405 | ||
406 | $site_footer:: | |
407 | Name of a file with HTML to be included at the bottom of each page. | |
408 | Relative to the directory containing the 'gitweb.cgi' script. | |
409 | Can be set using `GITWEB_SITE_FOOTER` at build time. No default | |
410 | value. | |
411 | ||
412 | $home_text:: | |
413 | Name of a HTML file which, if it exists, is included on the | |
414 | gitweb projects overview page ("projects_list" view). Relative to | |
415 | the directory containing the gitweb.cgi script. Default value | |
416 | can be adjusted during build time using `GITWEB_HOMETEXT` variable. | |
417 | By default set to 'indextext.html'. | |
418 | ||
419 | $projects_list_description_width:: | |
420 | The width (in characters) of the "Description" column of the projects list. | |
421 | Longer descriptions will be truncated (trying to cut at word boundary); | |
422 | the full description is available in the 'title' attribute (usually shown on | |
423 | mouseover). The default is 25, which might be too small if you | |
424 | use long project descriptions. | |
425 | ||
426 | $default_projects_order:: | |
427 | Default value of ordering of projects on projects list page, which | |
428 | means the ordering used if you don't explicitly sort projects list | |
429 | (if there is no "o" CGI query parameter in the URL). Valid values | |
430 | are "none" (unsorted), "project" (projects are by project name, | |
431 | i.e. path to repository relative to `$projectroot`), "descr" | |
432 | (project description), "owner", and "age" (by date of most current | |
433 | commit). | |
434 | + | |
435 | Default value is "project". Unknown value means unsorted. | |
436 | ||
437 | ||
438 | Changing gitweb's behavior | |
439 | ~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
440 | These configuration variables control _internal_ gitweb behavior. | |
441 | ||
442 | $default_blob_plain_mimetype:: | |
443 | Default mimetype for the blob_plain (raw) view, if mimetype checking | |
444 | doesn't result in some other type; by default "text/plain". | |
445 | Gitweb guesses mimetype of a file to display based on extension | |
446 | of its filename, using `$mimetypes_file` (if set and file exists) | |
68ed71b5 | 447 | and `/etc/mime.types` files (see *mime.types*(5) manpage; only |
6d3902b0 DN |
448 | filename extension rules are supported by gitweb). |
449 | ||
450 | $default_text_plain_charset:: | |
451 | Default charset for text files. If this is not set, the web server | |
452 | configuration will be used. Unset by default. | |
453 | ||
454 | $fallback_encoding:: | |
455 | Gitweb assumes this charset when a line contains non-UTF-8 characters. | |
456 | The fallback decoding is used without error checking, so it can be even | |
457 | "utf-8". The value must be a valid encoding; see the *Encoding::Supported*(3pm) | |
458 | man page for a list. The default is "latin1", aka. "iso-8859-1". | |
459 | ||
460 | @diff_opts:: | |
461 | Rename detection options for git-diff and git-diff-tree. The default is | |
462 | (\'-M'); set it to (\'-C') or (\'-C', \'-C') to also detect copies, | |
463 | or set it to () i.e. empty list if you don't want to have renames | |
464 | detection. | |
465 | + | |
466 | *Note* that rename and especially copy detection can be quite | |
2de9b711 | 467 | CPU-intensive. Note also that non Git tools can have problems with |
6d3902b0 DN |
468 | patches generated with options mentioned above, especially when they |
469 | involve file copies (\'-C') or criss-cross renames (\'-B'). | |
470 | ||
471 | ||
472 | Some optional features and policies | |
473 | ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ | |
474 | Most of features are configured via `%feature` hash; however some of extra | |
475 | gitweb features can be turned on and configured using variables described | |
476 | below. This list beside configuration variables that control how gitweb | |
477 | looks does contain variables configuring administrative side of gitweb | |
478 | (e.g. cross-site scripting prevention; admittedly this as side effect | |
479 | affects how "summary" pages look like, or load limiting). | |
480 | ||
481 | @git_base_url_list:: | |
2de9b711 | 482 | List of Git base URLs. These URLs are used to generate URLs |
6d3902b0 DN |
483 | describing from where to fetch a project, which are shown on |
484 | project summary page. The full fetch URL is "`$git_base_url/$project`", | |
485 | for each element of this list. You can set up multiple base URLs | |
486 | (for example one for `git://` protocol, and one for `http://` | |
487 | protocol). | |
488 | + | |
68ed71b5 | 489 | Note that per repository configuration can be set in `$GIT_DIR/cloneurl` |
6d3902b0 DN |
490 | file, or as values of multi-value `gitweb.url` configuration variable in |
491 | project config. Per-repository configuration takes precedence over value | |
492 | composed from `@git_base_url_list` elements and project name. | |
493 | + | |
494 | You can setup one single value (single entry/item in this list) at build | |
d7bfb9ee | 495 | time by setting the `GITWEB_BASE_URL` build-time configuration variable. |
6d3902b0 DN |
496 | By default it is set to (), i.e. an empty list. This means that gitweb |
497 | would not try to create project URL (to fetch) from project name. | |
498 | ||
499 | $projects_list_group_categories:: | |
270f0a8c | 500 | Whether to enable the grouping of projects by category on the project |
6d3902b0 DN |
501 | list page. The category of a project is determined by the |
502 | `$GIT_DIR/category` file or the `gitweb.category` variable in each | |
503 | repository's configuration. Disabled by default (set to 0). | |
504 | ||
505 | $project_list_default_category:: | |
506 | Default category for projects for which none is specified. If this is | |
507 | set to the empty string, such projects will remain uncategorized and | |
508 | listed at the top, above categorized projects. Used only if project | |
509 | categories are enabled, which means if `$projects_list_group_categories` | |
510 | is true. By default set to "" (empty string). | |
511 | ||
512 | $prevent_xss:: | |
513 | If true, some gitweb features are disabled to prevent content in | |
514 | repositories from launching cross-site scripting (XSS) attacks. Set this | |
515 | to true if you don't trust the content of your repositories. | |
516 | False by default (set to 0). | |
517 | ||
518 | $maxload:: | |
519 | Used to set the maximum load that we will still respond to gitweb queries. | |
520 | If the server load exceeds this value then gitweb will return | |
521 | "503 Service Unavailable" error. The server load is taken to be 0 | |
522 | if gitweb cannot determine its value. Currently it works only on Linux, | |
68ed71b5 | 523 | where it uses `/proc/loadavg`; the load there is the number of active |
6d3902b0 DN |
524 | tasks on the system -- processes that are actually running -- averaged |
525 | over the last minute. | |
526 | + | |
527 | Set `$maxload` to undefined value (`undef`) to turn this feature off. | |
528 | The default value is 300. | |
529 | ||
5710be46 KK |
530 | $omit_age_column:: |
531 | If true, omit the column with date of the most current commit on the | |
532 | projects list page. It can save a bit of I/O and a fork per repository. | |
533 | ||
0ebe7827 KK |
534 | $omit_owner:: |
535 | If true prevents displaying information about repository owner. | |
536 | ||
6d3902b0 DN |
537 | $per_request_config:: |
538 | If this is set to code reference, it will be run once for each request. | |
8d75a1d1 | 539 | You can set parts of configuration that change per session this way. |
6d3902b0 DN |
540 | For example, one might use the following code in a gitweb configuration |
541 | file | |
542 | + | |
543 | -------------------------------------------------------------------------------- | |
544 | our $per_request_config = sub { | |
545 | $ENV{GL_USER} = $cgi->remote_user || "gitweb"; | |
546 | }; | |
547 | -------------------------------------------------------------------------------- | |
548 | + | |
549 | If `$per_request_config` is not a code reference, it is interpreted as boolean | |
550 | value. If it is true gitweb will process config files once per request, | |
551 | and if it is false gitweb will process config files only once, each time it | |
552 | is executed. True by default (set to 1). | |
553 | + | |
554 | *NOTE*: `$my_url`, `$my_uri`, and `$base_url` are overwritten with their default | |
555 | values before every request, so if you want to change them, be sure to set | |
556 | this variable to true or a code reference effecting the desired changes. | |
557 | + | |
558 | This variable matters only when using persistent web environments that | |
559 | serve multiple requests using single gitweb instance, like mod_perl, | |
560 | FastCGI or Plackup. | |
561 | ||
562 | ||
563 | Other variables | |
564 | ~~~~~~~~~~~~~~~ | |
565 | Usually you should not need to change (adjust) any of configuration | |
566 | variables described below; they should be automatically set by gitweb to | |
567 | correct value. | |
568 | ||
569 | ||
570 | $version:: | |
571 | Gitweb version, set automatically when creating gitweb.cgi from | |
572 | gitweb.perl. You might want to modify it if you are running modified | |
573 | gitweb, for example | |
574 | + | |
575 | --------------------------------------------------- | |
576 | our $version .= " with caching"; | |
577 | --------------------------------------------------- | |
578 | + | |
579 | if you run modified version of gitweb with caching support. This variable | |
580 | is purely informational, used e.g. in the "generator" meta header in HTML | |
581 | header. | |
582 | ||
583 | $my_url:: | |
584 | $my_uri:: | |
585 | Full URL and absolute URL of the gitweb script; | |
586 | in earlier versions of gitweb you might have need to set those | |
587 | variables, but now there should be no need to do it. See | |
588 | `$per_request_config` if you need to set them still. | |
589 | ||
590 | $base_url:: | |
591 | Base URL for relative URLs in pages generated by gitweb, | |
592 | (e.g. `$logo`, `$favicon`, `@stylesheets` if they are relative URLs), | |
593 | needed and used '<base href="$base_url">' only for URLs with nonempty | |
594 | PATH_INFO. Usually gitweb sets its value correctly, | |
595 | and there is no need to set this variable, e.g. to $my_uri or "/". | |
596 | See `$per_request_config` if you need to override it anyway. | |
597 | ||
598 | ||
599 | CONFIGURING GITWEB FEATURES | |
600 | --------------------------- | |
601 | Many gitweb features can be enabled (or disabled) and configured using the | |
602 | `%feature` hash. Names of gitweb features are keys of this hash. | |
603 | ||
604 | Each `%feature` hash element is a hash reference and has the following | |
605 | structure: | |
606 | ---------------------------------------------------------------------- | |
607 | "<feature_name>" => { | |
608 | "sub" => <feature-sub (subroutine)>, | |
609 | "override" => <allow-override (boolean)>, | |
610 | "default" => [ <options>... ] | |
611 | }, | |
612 | ---------------------------------------------------------------------- | |
613 | Some features cannot be overridden per project. For those | |
614 | features the structure of appropriate `%feature` hash element has a simpler | |
615 | form: | |
616 | ---------------------------------------------------------------------- | |
617 | "<feature_name>" => { | |
618 | "override" => 0, | |
619 | "default" => [ <options>... ] | |
620 | }, | |
621 | ---------------------------------------------------------------------- | |
622 | As one can see it lacks the \'sub' element. | |
623 | ||
624 | The meaning of each part of feature configuration is described | |
625 | below: | |
626 | ||
627 | default:: | |
628 | List (array reference) of feature parameters (if there are any), | |
629 | used also to toggle (enable or disable) given feature. | |
630 | + | |
631 | Note that it is currently *always* an array reference, even if | |
632 | feature doesn't accept any configuration parameters, and \'default' | |
633 | is used only to turn it on or off. In such case you turn feature on | |
634 | by setting this element to `[1]`, and torn it off by setting it to | |
635 | `[0]`. See also the passage about the "blame" feature in the "Examples" | |
636 | section. | |
637 | + | |
638 | To disable features that accept parameters (are configurable), you | |
639 | need to set this element to empty list i.e. `[]`. | |
640 | ||
641 | override:: | |
642 | If this field has a true value then the given feature is | |
5fe8f49b | 643 | overridable, which means that it can be configured |
6d3902b0 DN |
644 | (or enabled/disabled) on a per-repository basis. |
645 | + | |
646 | Usually given "<feature>" is configurable via the `gitweb.<feature>` | |
2de9b711 | 647 | config variable in the per-repository Git configuration file. |
6d3902b0 | 648 | + |
5fe8f49b | 649 | *Note* that no feature is overridable by default. |
6d3902b0 DN |
650 | |
651 | sub:: | |
652 | Internal detail of implementation. What is important is that | |
653 | if this field is not present then per-repository override for | |
654 | given feature is not supported. | |
655 | + | |
656 | You wouldn't need to ever change it in gitweb config file. | |
657 | ||
658 | ||
659 | Features in `%feature` | |
660 | ~~~~~~~~~~~~~~~~~~~~~~ | |
661 | The gitweb features that are configurable via `%feature` hash are listed | |
662 | below. This should be a complete list, but ultimately the authoritative | |
663 | and complete list is in gitweb.cgi source code, with features described | |
664 | in the comments. | |
665 | ||
666 | blame:: | |
667 | Enable the "blame" and "blame_incremental" blob views, showing for | |
668 | each line the last commit that modified it; see linkgit:git-blame[1]. | |
669 | This can be very CPU-intensive and is therefore disabled by default. | |
670 | + | |
671 | This feature can be configured on a per-repository basis via | |
672 | repository's `gitweb.blame` configuration variable (boolean). | |
673 | ||
674 | snapshot:: | |
675 | Enable and configure the "snapshot" action, which allows user to | |
676 | download a compressed archive of any tree or commit, as produced | |
677 | by linkgit:git-archive[1] and possibly additionally compressed. | |
678 | This can potentially generate high traffic if you have large project. | |
679 | + | |
680 | The value of \'default' is a list of names of snapshot formats, | |
681 | defined in `%known_snapshot_formats` hash, that you wish to offer. | |
682 | Supported formats include "tgz", "tbz2", "txz" (gzip/bzip2/xz | |
683 | compressed tar archive) and "zip"; please consult gitweb sources for | |
684 | a definitive list. By default only "tgz" is offered. | |
685 | + | |
686 | This feature can be configured on a per-repository basis via | |
112ea426 | 687 | repository's `gitweb.snapshot` configuration variable, which contains |
6d3902b0 DN |
688 | a comma separated list of formats or "none" to disable snapshots. |
689 | Unknown values are ignored. | |
690 | ||
691 | grep:: | |
692 | Enable grep search, which lists the files in currently selected | |
693 | tree (directory) containing the given string; see linkgit:git-grep[1]. | |
694 | This can be potentially CPU-intensive, of course. Enabled by default. | |
695 | + | |
696 | This feature can be configured on a per-repository basis via | |
697 | repository's `gitweb.grep` configuration variable (boolean). | |
698 | ||
699 | pickaxe:: | |
700 | Enable the so called pickaxe search, which will list the commits | |
701 | that introduced or removed a given string in a file. This can be | |
702 | practical and quite faster alternative to "blame" action, but it is | |
703 | still potentially CPU-intensive. Enabled by default. | |
704 | + | |
705 | The pickaxe search is described in linkgit:git-log[1] (the | |
706 | description of `-S<string>` option, which refers to pickaxe entry in | |
707 | linkgit:gitdiffcore[7] for more details). | |
708 | + | |
709 | This feature can be configured on a per-repository basis by setting | |
710 | repository's `gitweb.pickaxe` configuration variable (boolean). | |
711 | ||
712 | show-sizes:: | |
713 | Enable showing size of blobs (ordinary files) in a "tree" view, in a | |
714 | separate column, similar to what `ls -l` does; see description of | |
715 | `-l` option in linkgit:git-ls-tree[1] manpage. This costs a bit of | |
716 | I/O. Enabled by default. | |
717 | + | |
718 | This feature can be configured on a per-repository basis via | |
da0005b8 | 719 | repository's `gitweb.showSizes` configuration variable (boolean). |
6d3902b0 DN |
720 | |
721 | patches:: | |
722 | Enable and configure "patches" view, which displays list of commits in email | |
723 | (plain text) output format; see also linkgit:git-format-patch[1]. | |
724 | The value is the maximum number of patches in a patchset generated | |
725 | in "patches" view. Set the 'default' field to a list containing single | |
726 | item of or to an empty list to disable patch view, or to a list | |
727 | containing a single negative number to remove any limit. | |
728 | Default value is 16. | |
729 | + | |
730 | This feature can be configured on a per-repository basis via | |
731 | repository's `gitweb.patches` configuration variable (integer). | |
732 | ||
733 | avatar:: | |
734 | Avatar support. When this feature is enabled, views such as | |
735 | "shortlog" or "commit" will display an avatar associated with | |
736 | the email of each committer and author. | |
737 | + | |
738 | Currently available providers are *"gravatar"* and *"picon"*. | |
739 | Only one provider at a time can be selected ('default' is one element list). | |
740 | If an unknown provider is specified, the feature is disabled. | |
741 | *Note* that some providers might require extra Perl packages to be | |
68ed71b5 | 742 | installed; see `gitweb/INSTALL` for more details. |
6d3902b0 DN |
743 | + |
744 | This feature can be configured on a per-repository basis via | |
745 | repository's `gitweb.avatar` configuration variable. | |
746 | + | |
747 | See also `%avatar_size` with pixel sizes for icons and avatars | |
748 | ("default" is used for one-line like "log" and "shortlog", "double" | |
749 | is used for two-line like "commit", "commitdiff" or "tag"). If the | |
750 | default font sizes or lineheights are changed (e.g. via adding extra | |
751 | CSS stylesheet in `@stylesheets`), it may be appropriate to change | |
752 | these values. | |
753 | ||
754 | highlight:: | |
755 | Server-side syntax highlight support in "blob" view. It requires | |
756 | `$highlight_bin` program to be available (see the description of | |
757 | this variable in the "Configuration variables" section above), | |
758 | and therefore is disabled by default. | |
759 | + | |
760 | This feature can be configured on a per-repository basis via | |
761 | repository's `gitweb.highlight` configuration variable (boolean). | |
762 | ||
763 | remote_heads:: | |
764 | Enable displaying remote heads (remote-tracking branches) in the "heads" | |
765 | list. In most cases the list of remote-tracking branches is an | |
766 | unnecessary internal private detail, and this feature is therefore | |
767 | disabled by default. linkgit:git-instaweb[1], which is usually used | |
768 | to browse local repositories, enables and uses this feature. | |
769 | + | |
770 | This feature can be configured on a per-repository basis via | |
771 | repository's `gitweb.remote_heads` configuration variable (boolean). | |
772 | ||
773 | ||
774 | The remaining features cannot be overridden on a per project basis. | |
775 | ||
776 | search:: | |
777 | Enable text search, which will list the commits which match author, | |
778 | committer or commit text to a given string; see the description of | |
779 | `--author`, `--committer` and `--grep` options in linkgit:git-log[1] | |
780 | manpage. Enabled by default. | |
781 | + | |
782 | Project specific override is not supported. | |
783 | ||
784 | forks:: | |
785 | If this feature is enabled, gitweb considers projects in | |
786 | subdirectories of project root (basename) to be forks of existing | |
6cf378f0 JK |
787 | projects. For each project +$projname.git+, projects in the |
788 | +$projname/+ directory and its subdirectories will not be | |
789 | shown in the main projects list. Instead, a \'\+' mark is shown | |
790 | next to +$projname+, which links to a "forks" view that lists all | |
791 | the forks (all projects in +$projname/+ subdirectory). Additionally | |
6d3902b0 DN |
792 | a "forks" view for a project is linked from project summary page. |
793 | + | |
6cf378f0 | 794 | If the project list is taken from a file (+$projects_list+ points to a |
6d3902b0 DN |
795 | file), forks are only recognized if they are listed after the main project |
796 | in that file. | |
797 | + | |
798 | Project specific override is not supported. | |
799 | ||
800 | actions:: | |
801 | Insert custom links to the action bar of all project pages. This | |
802 | allows you to link to third-party scripts integrating into gitweb. | |
803 | + | |
804 | The "default" value consists of a list of triplets in the form | |
805 | `("<label>", "<link>", "<position>")` where "position" is the label | |
806 | after which to insert the link, "link" is a format string where `%n` | |
807 | expands to the project name, `%f` to the project path within the | |
808 | filesystem (i.e. "$projectroot/$project"), `%h` to the current hash | |
809 | (\'h' gitweb parameter) and `%b` to the current hash base | |
810 | (\'hb' gitweb parameter); `%%` expands to \'%'. | |
811 | + | |
812 | For example, at the time this page was written, the http://repo.or.cz[] | |
2de9b711 | 813 | Git hosting site set it to the following to enable graphical log |
6d3902b0 DN |
814 | (using the third party tool *git-browser*): |
815 | + | |
816 | ---------------------------------------------------------------------- | |
817 | $feature{'actions'}{'default'} = | |
818 | [ ('graphiclog', '/git-browser/by-commit.html?r=%n', 'summary')]; | |
819 | ---------------------------------------------------------------------- | |
820 | + | |
821 | This adds a link titled "graphiclog" after the "summary" link, leading to | |
822 | `git-browser` script, passing `r=<project>` as a query parameter. | |
823 | + | |
824 | Project specific override is not supported. | |
825 | ||
826 | timed:: | |
2de9b711 | 827 | Enable displaying how much time and how many Git commands it took to |
6d3902b0 DN |
828 | generate and display each page in the page footer (at the bottom of |
829 | page). For example the footer might contain: "This page took 6.53325 | |
2de9b711 | 830 | seconds and 13 Git commands to generate." Disabled by default. |
6d3902b0 DN |
831 | + |
832 | Project specific override is not supported. | |

834 | javascript-timezone:: | |
0ffa154b | 835 | Enable and configure the ability to change a common time zone for dates |
6d3902b0 DN |
836 | in gitweb output via JavaScript. Dates in gitweb output include |
837 | authordate and committerdate in "commit", "commitdiff" and "log" | |
838 | views, and taggerdate in "tag" view. Enabled by default. | |
839 | + | |
0ffa154b JSJ |
840 | The value is a list of three values: a default time zone (for if the client |
841 | hasn't selected some other time zone and saved it in a cookie), a name of cookie | |
842 | where to store selected time zone, and a CSS class used to mark up | |
6d3902b0 DN |
843 | dates for manipulation. If you want to turn this feature off, set "default" |
844 | to empty list: `[]`. | |
845 | + | |
0ffa154b | 846 | Typical gitweb config files will only change starting (default) time zone, |
6d3902b0 DN |
847 | and leave other elements at their default values: |
848 | + | |
849 | --------------------------------------------------------------------------- | |
850 | $feature{'javascript-timezone'}{'default'}[0] = "utc"; | |
851 | --------------------------------------------------------------------------- | |
852 | + | |
853 | The example configuration presented here is guaranteed to be backwards | |
854 | and forward compatible. | |
855 | + | |
0ffa154b | 856 | Time zone values can be "local" (for local time zone that browser uses), "utc" |
6d3902b0 | 857 | (what gitweb uses when JavaScript or this feature is disabled), or numerical |
0ffa154b | 858 | time zones in the form of "+/-HHMM", such as "+0200". |

862 | extra-branch-refs:: |
863 | List of additional directories under "refs" which are going to | |
864 | be used as branch refs. For example if you have a gerrit setup | |
865 | where all branches under refs/heads/ are official, | |
866 | push-after-review ones and branches under refs/sandbox/, | |
867 | refs/wip and refs/other are user ones where permissions are | |
868 | much wider, then you might want to set this variable as | |
869 | follows: | |
870 | + | |
871 | -------------------------------------------------------------------------------- | |
872 | $feature{'extra-branch-refs'}{'default'} = | |
873 | ['sandbox', 'wip', 'other']; | |
874 | -------------------------------------------------------------------------------- | |
875 | + | |
876 | This feature can be configured on per-repository basis after setting | |
877 | $feature{'extra-branch-refs'}{'override'} to true, via repository's | |
878 | `gitweb.extraBranchRefs` configuration variable, which contains a | |
879 | space separated list of refs. An example: | |
880 | + | |
881 | -------------------------------------------------------------------------------- | |
882 | [gitweb] | |
883 | extraBranchRefs = sandbox wip other | |
884 | -------------------------------------------------------------------------------- | |
885 | + | |
886 | The gitweb.extraBranchRefs is actually a multi-valued configuration | |
887 | variable, so following example is also correct and the result is the | |
888 | same as of the snippet above: | |
889 | + | |
890 | -------------------------------------------------------------------------------- | |
891 | [gitweb] | |
892 | extraBranchRefs = sandbox | |
893 | extraBranchRefs = wip other | |
894 | -------------------------------------------------------------------------------- | |
895 | + | |
896 | It is an error to specify a ref that does not pass "git check-ref-format" | |
897 | scrutiny. Duplicated values are filtered. | |

900 | EXAMPLES | |
901 | -------- | |
902 | ||
903 | To enable blame, pickaxe search, and snapshot support (allowing "tar.gz" and | |
904 | "zip" snapshots), while allowing individual projects to turn them off, put | |
905 | the following in your GITWEB_CONFIG file: | |
906 | ||
9aab3fcf AH |
907 | -------------------------------------------------------------------------------- |
908 | $feature{'blame'}{'default'} = [1]; | |
909 | $feature{'blame'}{'override'} = 1; | |
6d3902b0 | 910 | |
9aab3fcf AH |
911 | $feature{'pickaxe'}{'default'} = [1]; |
912 | $feature{'pickaxe'}{'override'} = 1; | |
6d3902b0 | 913 | |
9aab3fcf AH |
914 | $feature{'snapshot'}{'default'} = ['zip', 'tgz']; |
915 | $feature{'snapshot'}{'override'} = 1; | |
916 | -------------------------------------------------------------------------------- | |
6d3902b0 DN |
917 | |
918 | If you allow overriding for the snapshot feature, you can specify which | |
06ab60c0 | 919 | snapshot formats are globally disabled. You can also add any command-line |
6d3902b0 DN |
920 | options you want (such as setting the compression level). For instance, you |
921 | can disable Zip compressed snapshots and set *gzip*(1) to run at level 6 by | |
922 | adding the following lines to your gitweb configuration file: | |
923 | ||
924 | $known_snapshot_formats{'zip'}{'disabled'} = 1; | |
925 | $known_snapshot_formats{'tgz'}{'compressor'} = ['gzip','-6']; | |

927 | BUGS |
928 | ---- | |
929 | Debugging would be easier if the fallback configuration file | |
930 | (`/etc/gitweb.conf`) and environment variable to override its location | |
931 | ('GITWEB_CONFIG_SYSTEM') had names reflecting their "fallback" role. | |
932 | The current names are kept to avoid breaking working setups. | |
933 | ||
6d3902b0 DN |
934 | ENVIRONMENT |
935 | ----------- | |
936 | The location of per-instance and system-wide configuration files can be | |
937 | overridden using the following environment variables: | |
938 | ||
939 | GITWEB_CONFIG:: | |
940 | Sets location of per-instance configuration file. | |
941 | GITWEB_CONFIG_SYSTEM:: | |
942 | Sets location of fallback system-wide configuration file. | |
943 | This file is read only if per-instance one does not exist. | |
944 | GITWEB_CONFIG_COMMON:: | |
945 | Sets location of common system-wide configuration file. | |
946 | ||
947 | ||
948 | FILES | |
949 | ----- | |
950 | gitweb_config.perl:: | |
951 | This is default name of per-instance configuration file. The | |
952 | format of this file is described above. | |
953 | /etc/gitweb.conf:: | |
954 | This is default name of fallback system-wide configuration | |
955 | file. This file is used only if per-instance configuration | |
956 | variable is not found. | |
957 | /etc/gitweb-common.conf:: | |
958 | This is default name of common system-wide configuration | |
959 | file. | |
