Subject: [PATCH] git_async_cat: unref pipes on EOF from git->cleanup
Date: Sun, 5 Jul 2020 22:50:45 +0000 [thread overview]
Message-ID: <20200705225045.29291-1-e@yhbt.net> (raw)
We avoided a managed circular reference in 10ee3548084c125f
but introduced a pipe FD leak, instead. So handle the EOF
we get when the "git cat-file --batch" process exits and
closes its stdout FD.
Fixes: 10ee3548084c125f ("git_async_cat: remove circular reference")
