Subject: [PATCH v2 02/12] commit-graph: verify file header information
Date: Fri, 11 May 2018 21:15:16 +0000 [thread overview]
Message-ID: <20180511211504.79877-3-dstolee@microsoft.com> (raw)
In-Reply-To: <20180511211504.79877-1-dstolee@microsoft.com>
During a run of 'git commit-graph verify', list the issues with the
header information in the commit-graph file. Some of this information
is inferred from the loaded 'struct commit_graph'. Some header
information is checked as part of load_commit_graph_one().
