[PATCH 16/28] http: stop leaking buffer in http_get_info_packs()

From
Jeff King <peff@peff.net>
Date
Sep 24, 2024, 22:02 UTC
Message-ID
<20240924220227.GP1143820@coredump.intra.peff.net>

We use http_get_strbuf() to fetch the remote info/packs content into a strbuf, but never free it, causing a leak. There's no need to hold onto it, as we've already parsed it completely.

This lets us mark t5619 as leak-free.
