Before 14111fc4 (git: submodule honor -c credential.* from command line, 2016-02-29), it was sufficient for code which spawned a process in a submodule to just set the child process's "env" field to "local_repo_env" to clear the environment of any repo-specific variables. That commit introduced a more complicated procedure, in which we clear most variables but allow through sanitized config. For C code, we used that procedure only for cloning, but not for any of the programs spawned by submodule.c. As a result, things like "git fetch --recurse-submodules" behave differently than "git clone --recursive"; the former will not pass through the sanitized config. We can fix this by using prepare_submodule_repo_env() everywhere in submodule.c. Signed-off-by: NJeff King <peff@peff.net> Signed-off-by: NJunio C Hamano <gitster@pobox.com>
