From: Johannes Schindelin Date: Fri, 9 Mar 2007 02:50:06 +0000 (+0100) Subject: git-bundle: prevent overwriting existing bundles X-Git-Tag: v1.5.1-rc1~50^2 X-Git-Url: http://git.tremily.us/?a=commitdiff_plain;h=2e578f9a4f08ade4e8da52614c566e5dc1c8ca00;p=git.git 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".
