Hi there,
While bumping Git's version for our Linux distribution to 2.14.1, I've
run in to a new test failure in t6500-gc.sh. This is the output of
the failing test with debug=t verbose=t:
expecting success:
# make sure we run a background auto-gc
test_commit make-pack &&
git repack &&
test_config gc.autopacklimit 1 &&
test_config gc.autodetach true &&
# create a ref whose loose presence we can use to detect a
pack-refs run
git update-ref refs/heads/should-be-loose HEAD &&
test_path_is_file .git/refs/heads/should-be-loose &&
# now fake a concurrent gc that holds the lock; we can use our
# shell pid so that it looks valid.
hostname=$(hostname || echo unknown) &&
printf "$$ %s" "$hostname" >.git/gc.pid &&
# our gc should exit zero without doing anything

I admit I am mostly blind with the Git gc system. Should I use strace
on the git-gc process at the end? How would I accomplish that? Is
there a better way of debugging this error further?
Core system stats:
Intel x86_64 E3-1280 v3 @ 3.60 GHz
musl libc 1.1.16+20
git 2.14.1, vanilla except for a patch to an earlier test due to
musl's inability to cope with EUC-JP
bash 4.3.48(1)-release
Thank you very much.
All the best,
