Subject: [PATCH v5 03/22] sequencer: stop leaking buf
Date: Tue, 7 Apr 2020 10:27:50 -0400 [thread overview]
Message-ID: <76585e5b1367a3adf18d761b2af9356ee64b46fd.1586269543.git.liu.denton@gmail.com> (raw)
In-Reply-To: <cover.1586269542.git.liu.denton@gmail.com>
In read_populate_opts(), we call read_oneliner() _after_ calling
strbuf_release(). This means that `buf` is leaked at the end of the
function.
Always clean up the strbuf by going to `done_rebase_i` whether or not
we return an error.
