Fix config API a memory leak added ina452128a36(submodule--helper: introduce add-config subcommand, 2021-08-06) by using the *_tmp() variant of git_config_get_string(). In this case we're only checking whether the (repo|git)_config_get_string() call is telling us that the "submodule.active" key exists. As with the preceding commit we'll find many other such patterns in the codebase if we go fishing. E.g. "git gc" leaks in the code added in61f7a383d3(maintenance: use 'incremental' strategy by default, 2020-10-15). Similar code in "git gc" added inb08ff1fee0(maintenance: add --schedule option and config, 2020-09-11) doesn't leak, but we could avoid the malloc() & free() in that case. A coccinelle rule to find those would find and fix some leaks, and cases where we're doing needless malloc() + free()'s but only care about the key existence, or are copying the (repo|git)_config_get_string() return value right away. But as with the preceding commit let's punt on all of that for now, and just narrowly fix this specific case in submodule--helper.

test_description='Test with test-tool submodule is-active
|
|
|
|
This test verifies that `test-tool submodule is-active` correctly identifies
|
|
submodules which are "active" and interesting to the user.
|
|
|
|
This is a unit test of the submodule.c is_submodule_active() function,
|
|
which is also indirectly tested elsewhere.
