Subject: [PATCH v2 11/25] count-objects: do not use xsize_t when counting object size
Date: Wed, 15 Oct 2014 18:40:58 -0400	[thread overview]
Message-ID: <20141015224058.GK25630@peff.net> (raw)
In-Reply-To: <20141015223244.GA25368@peff.net>

The point of xsize_t is to safely cast an off_t into a size_t
(because we are about to mmap). But in count-objects, we are
summing the sizes in an off_t. Using xsize_t means that
count-objects could fail on a 32-bit system with a 4G
object (not likely, as other parts of git would fail, but
we should at least be correct here).
