Subject: [PATCH v4 4/7] submodule--helper: use correct display path helper
Date: Thu, 30 Jun 2022 19:11:54 -0700 [thread overview]
Message-ID: <20220701021157.88858-5-chooglen@google.com> (raw)
In-Reply-To: <20220701021157.88858-1-chooglen@google.com>
Replace a chunk of code in update_submodule() with an equivalent
do_get_submodule_displaypath() invocation. This is already tested by
t/t7406-submodule-update.sh:'submodule update --init --recursive from
subdirectory', so no tests are added.
The two are equivalent because:
- Exactly one of recursive_prefix|prefix is non-NULL at a time; prefix
is set at the superproject level, and recursive_prefix is set when
recursing into submodules. There is also a BUG() statement in
get_submodule_displaypath() that asserts that both cannot be non-NULL.
- In get_submodule_displaypath(), get_super_prefix() always returns NULL
because "--super-prefix" is never passed. Thus calling it is
equivalent to calling do_get_submodule_displaypath() with super_prefix
= NULL.
Therefore:
- When recursive_prefix is non-NULL, prefix is NULL, and thus
get_submodule_displaypath() just returns prefixed_path. This is
identical to calling do_get_submodule_displaypath() with super_prefix
= recursive_prefix because the return value is still the concatenation
of recursive_prefix + update_data->sm_path.
- When prefix is non-NULL, prefixed_path = update_data->sm_path. Thus
calling get_submodule_displaypath() with prefixed_path is equivalent
to calling do_get_submodule_displaypath() with update_data->sm_path
