cgit - cgi for git
-This is an attempt to create a fast web interface for the git scm, using a
-frontside cache to decrease server io-pressure.
+This is an attempt to create a fast web interface for the git scm, using a
+builtin cache to decrease server io-pressure.
-When cgit is invoked, it looks for a cached page matching the request. If no
-such cachefile exist (or it has expired), it is (re)generated. Finally, the
-cachefile is returned to the client.
-If the cachefile has expired, but cgit is unable to lock the cachefile, the
-client will get the stale cachefile after all. This is done to favour page
-throughput over page freshness.
+$ $EDITOR Makefile
+$ sudo make install
+Note: cgit requires the git and xdiff libraries. Currently, the makefile
+expects these files to be found in '../git/libgit.a' and '../git/xdiff/lib.a',
+where they will be if you have built git from source in a parallell directory.
-Also, when a cachefile is generated, a few cache-related http-headers are
-created: "Modified" is set to current time(2), while "Expires" is set to
-time(2) + <cachefile TTL> * 60 (unless the TTL is negative, in which case it
-is read as "60 * 60 * 24 * 365"). This is done to avoid repeated requests for
-already visited pages.
-The following cache-related options can be set in /etc/cgitrc:
+The file /etc/cgitrc is read by cgit before handling a request. A template
+cgitrc is shipped with the sources, and all parameters and default values
+can be found in this file.
- cache-root=<path> root directory for cache files
- cache-root-ttl=<min> TTL for the repo listing page
- cache-repo-ttl=<min> TTL for repo summary pages
- cache-dynamic-ttl=<min> TTL for pages with symbolic references
- cache-static-ttl=<min> TTL for pages with sha1 references
-The cachefiles are split into different directories, based on the requested
-repository and page:
+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.
- Repo listing: <cachedir>/index.html
- Repo summary: <cachedir>/<repo>/index.html
- Repo subpage: <cachedir>/<repo>/<page>/<querystring>.html
+The generated content contains the complete response to the client, including
+the http-headers "Modified" and "Expires".
