Subject: [PATCH v3 16/28] receive-pack: reorder some code in unpack()
Date: Mon, 25 Nov 2013 10:55:42 +0700 [thread overview]
Message-ID: <1385351754-9954-17-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1385351754-9954-1-git-send-email-pclouds@gmail.com>
This is the preparation for adding --shallow-file to both
unpack-objects and index-pack. To sum up:
- status/code, ip/child, unpacker/keeper and i (now ac) are moved out
to function top level
- successful flow now ends at the end of the function
