From 2e578f9a4f08ade4e8da52614c566e5dc1c8ca00 Mon Sep 17 00:00:00 2001 From: Johannes Schindelin Date: Fri, 9 Mar 2007 03:50:06 +0100 Subject: [PATCH] git-bundle: prevent overwriting existing bundles Not only does it prevent accidentally losing older bundles, but it also fixes a subtle bug: when writing into an existing bundle, git-pack-objects would not truncate the bundle. Therefore, fetching from the bundle would trigger an error in unpack-objects: "fatal: pack has junk at the end".
