From 8b0eca7c7b73d0dc5d49f400a878d9b781ec4bec Mon Sep 17 00:00:00 2001 From: "Dana L. How" Date: Wed, 2 May 2007 12:13:14 -0400 Subject: Create pack-write.c for common pack writing code Include a generalized fixup_pack_header_footer() in this new file. Needed by git-repack --max-pack-size feature in a later patchset. [sp: Moved close(pack_fd) to callers, to support index-pack, and changed name to better indicate it is for packfiles.] Signed-off-by: Dana L. How Signed-off-by: Shawn O.
