Subject: [PATCH v2 12/45] parse_pathspec: support stripping/checking submodule paths
Date: Wed, 20 Mar 2013 19:16:16 +0700 [thread overview]
Message-ID: <1363781779-14947-4-git-send-email-pclouds@gmail.com> (raw)
In-Reply-To: <1363781779-14947-1-git-send-email-pclouds@gmail.com>
PATHSPEC_SYMLINK_LEADING_PATH and _STRIP_SUBMODULE_SLASH_EXPENSIVE are
respectively the alternate implementation of
pathspec.c:die_if_path_beyond_symlink() and
pathspec.c:check_path_for_gitlink(). They are intended to replace
those functions when builtin/add.c and builtin/check-ignore.c are
converted to use parse_pathspec.
