Subject: [PATCH 0/2] Clean up leaks in commit-graph.c
Date: Tue, 02 Oct 2018 07:58:43 -0700 (PDT) [thread overview]
Message-ID: <pull.42.git.gitgitgadget@gmail.com> (raw)
While looking at the commit-graph code, I noticed some memory leaks. These
can be found by running
valgrind --leak-check=full ./git commit-graph write --reachable
The impact of these leaks are small, as we never call write_commit_graph
_reachable in a loop, but it is best to be diligent here.
While looking at memory consumption within write_commit_graph(), I noticed
that we initialize our oid list with "object count / 4", which seems to be a
huge over-count. I reduce this by a factor of eight.
I built off of ab/commit-graph-progress, because my patch involves lines
close to those changes.
Thanks, -Stolee
