From 42526b478e369d7e8c9a95186ad87fae9930eea5 Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Fri, 30 Oct 2009 17:47:33 -0700 Subject: Add stateless RPC options to upload-pack, receive-pack When --stateless-rpc is passed as a command line parameter to upload-pack or receive-pack the programs now assume they may perform only a single read-write cycle with stdin and stdout. This fits with the HTTP POST request processing model where a program may read the request, write a response, and must exit. When --advertise-refs is passed as a command line parameter only the initial ref advertisement is output, and the program exits immediately. This fits with the HTTP GET request model, where no request content is received but a response must be produced. HTTP headers and/or environment are not processed here, but instead are assumed to be handled by the program invoking either service backend. Signed-off-by: Shawn O.
