The "oid-array" test helper can supposedly work without a Git repository, but will in fact crash because `the_repository->hash_algo` is not initialized. This is because `oid_pos()`, which is used by `oid_array_lookup()`, depends on `the_hash_algo->rawsz`. Ideally, we'd adapt `oid_pos()` to not depend on `the_hash_algo` anymore. That is a bigger untertaking though, so instead we fall back to SHA1 when there is no repository. Signed-off-by: Patrick Steinhardt <ps@pks.im> Signed-off-by: Junio C Hamano <gitster@pobox.com>
