Git does quite a lot of platform-specific detection in its Makefile, which can result in it defining preprocessor variables that are used in its header files. If CGit does not define the same variables it can result in different sizes of some structures in different places in the same application. For example, on Solaris Git uses it's "compat" regex library which has a different sized regex_t structure than that available in the platform regex.h. This has a knock-on effect on the size of "struct rev_info" and leads to hard to diagnose runtime issues. In order to avoid all of this, introduce a "cgit.mk" file that includes Git's Makefile and make all of the existing logic apply to CGit's objects as well. This is slightly complicated because Git's Makefile must run in Git's directory, so all references to CGit files need to be prefixed with "../". In addition, OBJECTS is a simply expanded variable in Git's Makefile so we cannot just add our objects to it. Instead we must copy the two applicable rules into "cgit.mk". This has the advantage that we can split CGit-specific CFLAGS from Git's CFLAGS and hence avoid rebuilding all of Git whenever a CGit-specific value changes.

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 1.7.4
-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 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 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".
