Move away from the "struct ref_list" in bundle.c in favor of the almost identical string-list.c API. That API fits this use-case perfectly, but did not exist in its current form when this code was added in2e0afafebd(Add git-bundle: move objects and references by archive, 2007-02-22), with hindsight we could have used the path-list API, which later got renamed to string-list. See8fd2cb4069(Extract helper bits from c-merge-recursive work, 2006-07-25) We need to change "name" to "string" and "oid" to "util" to make this conversion, but other than that the APIs are pretty much identical for what bundle.c made use of. Let's also replace the memset(..,0,...) pattern with a more idiomatic "INIT" macro, and finally add a *_release() function so to free the allocated memory. Before this the add_to_ref_list() would leak memory, now e.g. "bundle list-heads" reports no memory leaks at all under valgrind. In the bundle_header_init() function we're using a clever trick to memcpy() what we'd get from the corresponding BUNDLE_HEADER_INIT. There is a concurrent series to make use of that pattern more generally, see [1]. 1. https://lore.kernel.org/git/cover-0.5-00000000000-20210701T104855Z-avarab@gmail.com/ Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Acked-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>
