Subject: [PATCH 06/23] midx: struct midxed_git and 'read' subcommand
Date: Thu,  7 Jun 2018 10:03:21 -0400
Message-ID: <20180607140338.32440-7-dstolee@microsoft.com> (raw)
In-Reply-To: <20180607140338.32440-1-dstolee@microsoft.com>

As we build the multi-pack-index feature by adding chunks at a time,
we want to test that the data is being written correctly.

Create struct midxed_git to store an in-memory representation of a
multi-pack-index and a memory-map of the binary file. Initialize this
struct in load_midxed_git(object_dir).

Create the 'git midx read' subcommand to output basic information about
the multi-pack-index file. This will be expanded as more information is
written to the file.
