Subject: [PATCH v2 1/5] pack-bitmap.c: continue looping when first MIDX bitmap is found
Date: Thu, 21 Apr 2022 21:26:36 +0800	[thread overview]
Message-ID: <1bfd2fb6ab01af689fc6495e2f32d3f64c19f4b7.1650547400.git.dyroneteng@gmail.com> (raw)
In-Reply-To: <cover.1650547400.git.dyroneteng@gmail.com>

In "open_midx_bitmap()", we do a loop with the MIDX(es) in repo, when
the first one has been found, then will break out by a "return"
directly.

But actually, it's better to don't stop the loop until we have visited
both the MIDX in our repository, as well as any alternates (along with
_their_ alternates, recursively).
