From 28754ab5f0ce9b4f6ca1641c3e10e2c68bd9b3fc Mon Sep 17 00:00:00 2001 From: "Shawn O. Pearce" Date: Fri, 30 Oct 2009 17:47:24 -0700 Subject: Move "get_ack()" back to fetch-pack In 41cb7488 Linus moved this function to connect.c for reuse inside of the git-clone-pack command. That was 2005, but in 2006 Junio retired git-clone-pack in commit efc7fa53. Since then the only caller has been fetch-pack. Since this ACK/NAK exchange is only used by the fetch-pack/upload-pack protocol we should move it back to be a private detail of fetch-pack. Signed-off-by: Shawn O.
