It was reported that git-verify-pack(1) has started to crash with Git
v2.46.0 when run outside of a repository. This is another fallout from
c8aed5e8da
(repository: stop setting SHA1 as the default object hash,
2024-05-07), where we have stopped setting the default hash algorithm
for `the_repository`. Consequently, code that relies on `the_hash_algo`
will now crash when it hasn't explicitly been initialized, which may be
the case when running outside of a Git repository.
The crash is not in git-verify-pack(1) but instead in git-index-pack(1),
which gets called by the former. Ideally, both of these programs should
be able to identify the hash algorithm used by the packfile and index
without having to rely on external information. But unfortunately, the
format for neither of them is completely self-describing, so it is not
possible to derive that information. This is a design issue that we
should address by introducing a new packfile version that encodes its
object hash.
For now though the more important fix is to not make either of these
programs crash anymore, which we do by falling back to SHA1 when the
object hash is unconfigured. This pessimizes reading packfiles which
use a different hash than SHA1, but restores previous behaviour.
