cgit - CGI for Git
|
|
==================
|
|
|
|
This is an attempt to create a fast web interface for the Git SCM, using a
|
|
built-in cache to decrease server I/O pressure.
|
|
|
|
Installation
|
|
------------
|
|
|
|
Building cgit involves building a proper version of Git. How to do this
|
|
depends on how you obtained the cgit sources:
|
|
|
|
a) If you're working in a cloned cgit repository, you first need to
|
|
initialize and update the Git submodule:
|
|
|
|
$ git submodule init # register the Git submodule in .git/config
|
|
$ $EDITOR .git/config # if you want to specify a different url for git
|
|
$ git submodule update # clone/fetch and checkout correct git version
|
|
|
|
b) If you're building from a cgit tarball, you can download a proper git
|
|
version like this:
|
|
|
|
$ make get-git
|
|
|
|
When either a) or b) has been performed, you can build and install cgit like
|
|
this:
|
|
|
|
$ make
|
|
$ sudo make install
|
|
|
|
This will install `cgit.cgi` and `cgit.css` into `/var/www/htdocs/cgit`. You
|
|
can configure this location (and a few other things) by providing a `cgit.conf`
|
|
file (see the Makefile for details).
|
|
|
|
If you'd like to compile without Lua support, you may use:
|
|
|
|
$ make NO_LUA=1
|
|
|
|
And if you'd like to specify a Lua implementation, you may use:
|
|
|
|
$ make LUA_PKGCONFIG=lua5.1
|
|
|
|
If this is not specified, the Lua implementation will be auto-detected,
|
|
preferring LuaJIT if many are present. Acceptable values are generally "lua",
|
|
"luajit", "lua5.1", and "lua5.2".
|
|
|
|
|
|
Dependencies
|
|
------------
|
|
|
|
* libzip
|
|
* libcrypto (OpenSSL)
|
|
* libssl (OpenSSL)
|
|
* optional: luajit or lua, most reliably used when pkg-config is available
|
|
|
|
Apache configuration
|
|
--------------------
|
|
|
|
A new `Directory` section must probably be added for cgit, possibly something
|
|
like this:
|
|
|
|
<Directory "/var/www/htdocs/cgit/">
|
|
AllowOverride None
|
|
Options +ExecCGI
|
|
Order allow,deny
|
|
Allow from all
|
|
</Directory>
|
|
|
|
|
|
Runtime configuration
|
|
---------------------
|
|
|
|
The file `/etc/cgitrc` is read by cgit before handling a request. In addition
|
|
to runtime parameters, this file may also contain a list of repositories
|
|
displayed by cgit (see `cgitrc.5.txt` for further details).
|
|
|
|
The cache
|
|
---------
|
|
|
|
When cgit is invoked it looks for a cache file matching the request and
|
|
returns it to the client. If no such cache file exists (or if it has expired),
|
|
the content for the request is written into the proper cache file before the
|
|
file is returned.
|
|
|
|
If the cache file has expired but cgit is unable to obtain a lock for it, the
|
|
stale cache file is returned to the client. This is done to favour page
|
|
throughput over page freshness.
|
|
|
|
The generated content contains the complete response to the client, including
|
|
the HTTP headers `Modified` and `Expires`.
|
