Smart fetch and push over HTTP: server side
Requests for $GIT_URL/git-receive-pack and $GIT_URL/git-upload-pack are forwarded to the corresponding backend process by directly executing it and leaving stdin and stdout connected to the invoking web server. Prior to starting the backend process the HTTP response headers are sent, thereby freeing the backend from needing to know about the HTTP protocol. Requests that are encoded with Content-Encoding: gzip are automatically inflated before being streamed into the backend. This is primarily useful for the git-upload-pack backend, which receives highly repetitive text data from clients that easily compresses to 50% of its original size. Signed-off-by: Shawn O.
