Subject: [PATCH 2/8] submodule: add die_in_unpopulated_submodule function
Date: Tue, 9 May 2017 12:17:59 -0700 [thread overview]
Message-ID: <20170509191805.176266-3-bmwill@google.com> (raw)
In-Reply-To: <20170509191805.176266-1-bmwill@google.com>
Currently 'git add' is the only command which dies when launched from an
unpopulated submodule (the place-holder directory for a submodule which
hasn't been checked out). This is triggered implicitly by passing the
PATHSPEC_STRIP_SUBMODULE_SLASH_EXPENSIVE flag to 'parse_pathspec()'.
Instead make this desire more explicit by creating a function
'die_in_unpopulated_submodule()' which dies if the provided 'prefix' has
a leading path component which matches a submodule in the the index.
