cgit - cgi for git
|
|
|
|
|
|
This is an attempt to create a fast web interface for the git scm, using a
|
|
builtin cache to decrease server io-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).
|
|
|
|
|
|
Dependencies:
|
|
-git 1.5.3
|
|
-zip lib
|
|
-crypto lib
|
|
-openssl lib
|
|
|
|
|
|
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 also contains a list of the repositories
|
|
displayed by cgit.
|
|
|
|
A template cgitrc is shipped with the sources, and all parameters and default
|
|
values are documented in this file.
|
|
|
|
|
|
The cache
|
|
|
|
When cgit is invoked it looks for a cachefile matching the request and
|
|
returns it to the client. If no such cachefile exist (or if it has expired),
|
|
the content for the request is written into the proper cachefile before the
|
|
file is returned.
|
|
|
|
If the cachefile has expired but cgit is unable to obtain a lock for it, the
|
|
stale cachefile 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".
|
|
|
|
|
|
The missing features
|
|
|
|
* Submodule links in the directory listing page have a fixed format per
|
|
repository. This should probably be extended to a generic map between
|
|
submodule path and url.
|
|
|
|
* Branch- and tag-lists in the summary page can get very long, they should
|
|
probably only show something like the ten "latest modified" branches and
|
|
a similar number of "most recent" tags.
|
|
|
|
* There should be a new page for browsing refs/heads and refs/tags, with links
|
|
from the summary page whenever the branch/tag lists overflow.
|
|
|
|
* The log-page should have more/better search options (author, committer,
|
|
pickaxe, paths) and possibly support arbitrary revision specifiers.
|
|
|
|
* A set of test-scripts is required before cgit-1.0 can be released.
