grep: search history of moved submodules
If a submodule was renamed at any point since it's inception then if you were to try and grep on a commit prior to the submodule being moved, you wouldn't be able to find a working directory for the submodule since the path in the past is different from the current path. This patch teaches grep to find the .git directory for a submodule in the parents .git/modules/ directory in the event the path to the submodule in the commit that is being searched differs from the state of the currently checked out commit. If found, the child process that is spawned to grep the submodule will chdir into its gitdir instead of a working directory. In order to override the explicit setting of submodule child process's gitdir environment variable (which was introduced in '10f5c526') `GIT_DIR_ENVIORMENT` needs to be pushed onto child process's env_array. This allows the searching of history from a submodule's gitdir, rather than from a working directory. Signed-off-by: Brandon Williams <> Signed-off-by: Junio C Hamano <>
