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. 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. 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: 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: Repo listing: <cachedir>/index.html Repo summary: <cachedir>/<repo>/index.html Repo subpage: <cachedir>/<repo>/<page>/<querystring>.html
