Subject: [PATCH v2 5/8] commit-graph: don't pass filename to load_commit_graph_one_fd_st()
Date: Thu, 14 Mar 2019 22:47:37 +0100	[thread overview]
Message-ID: <20190314214740.23360-6-avarab@gmail.com> (raw)
In-Reply-To: <20190221223753.20070-1-avarab@gmail.com>

An earlier change implemented load_commit_graph_one_fd_st() in a way
that was bug-compatible with earlier code in terms of the "graph file
%s is too small" error message printing out the path to the
commit-graph (".git/objects/info/commit-graph").

But change that, because:

 * A function that takes an already-open file descriptor also needing
   the filename isn't very intuitive.

 * The vast majority of errors we might emit when loading the graph
   come from parse_commit_graph(), which doesn't report the
   filename. Let's not do that either in this case for consistency.
