Subject: [PATCH 04/10] name-rev: don't leak path copy in name_ref()
Date: Tue, 4 Feb 2020 22:17:02 +0100 [thread overview]
Message-ID: <32a0a2d6-3237-24e9-c647-6624cc2a1e89@web.de> (raw)
In-Reply-To: <084909f8-fefa-1fe0-b2ce-74eff47c4972@web.de>
name_ref() duplicates the path string and passes it to name_rev(), which
either puts it into a commit slab or ignores it if there is already a
better name, leaking it. Move the duplication to name_rev() and release
the copy in the latter case.
