With this change, the required syntax is: $ git submodule add URL path Specifically, this eliminates the form $ git submodule add URL which was confused by more than one person as $ git submodule add path With this patch, the URL locating the submodule's origin repository can be either an absolute URL, or (if it begins with ./ or ../) can express the submodule's repository location relative to the superproject's origin. This patch also eliminates a third form of URL, which was relative to the superproject's top-level directory (not its repository). Any URL that was neither absolute nor matched ./\|../ was assumed to point to a subdirectory of the superproject as the location of the submodule's origin repository. This URL form was confusing and does not seem to correspond to an important use-case. Specifically, no-one has identified the need to clone from a repository already in the superproject's tree, but if this is needed it is easily done using an absolute URL: $(pwd)/relative-path. So, no functionality is lost with this patch. (t6008-rev-list-submodule.sh did rely upon this relative URL, fixed by using $(pwd).) Following this change, there are exactly four variants of submodule-add, as both arguments have two flavors: URL can be absolute, or can begin with ./\|../ and thus names the submodule's origin relative to the superproject's origin. Note: With this patch, "submodule add" discerns an absolute URL as matching /\|:: e.g., URL begins with /, or it contains a :. This works for all valid URLs, an absolute path in POSIX, as well as an absolute path on Windows). path can either already exist as a valid git repo, or will be cloned from the given URL. The first form here eases creation of a new submodule in an existing superproject as the submodule can be added and tested in-tree before pushing to the public repository. However, the more usual form is the second, where the repo is cloned from the given URL. This specifically addresses the issue of $ git submodule add a/b/c attempting to clone from a repository at "a/b/c" to create a new module in "c". This also simplifies description of "relative URL" as there is now exactly one* form: a URL relative to the parent's origin repo.

git-submodule - make "submodule add" more strict, and document it

This change makes "submodule add" much more strict in the arguments it
takes, and is intended to address confusion as recently noted on the
git-list. With this change, the required syntax is:

	$ git submodule add URL path

Specifically, this eliminates the form

	$ git submodule add URL

which was confused by more than one person as

	$ git submodule add path

With this patch, the URL locating the submodule's origin repository can be
either an absolute URL, or (if it begins with ./ or ../) can express the
submodule's repository location relative to the superproject's origin.

This patch also eliminates a third form of URL, which was relative to the
superproject's top-level directory (not its repository).  Any URL that was
neither absolute nor matched ./*|../* was assumed to point to a
subdirectory of the superproject as the location of the submodule's origin
repository.  This URL form was confusing and does not seem to correspond
to an important use-case.  Specifically, no-one has identified the need to
clone from a repository already in the superproject's tree, but if this is
needed it is easily done using an absolute URL: $(pwd)/relative-path.  So,
no functionality is lost with this patch. (t6008-rev-list-submodule.sh did
rely upon this relative URL, fixed by using $(pwd).)

Following this change, there are exactly four variants of
submodule-add, as both arguments have two flavors:

URL can be absolute, or can begin with ./|../ and thus names the
submodule's origin relative to the superproject's origin.

Note: With this patch, "submodule add" discerns an absolute URL as
matching /*|*:*: e.g., URL begins with /, or it contains a :.  This works
for all valid URLs, an absolute path in POSIX, as well as an absolute path
on Windows).

path can either already exist as a valid git repo, or will be cloned from
the given URL.  The first form here eases creation of a new submodule in
an existing superproject as the submodule can be added and tested in-tree
before pushing to the public repository.  However, the more usual form is
the second, where the repo is cloned from the given URL.

This specifically addresses the issue of

	$ git submodule add a/b/c

attempting to clone from a repository at "a/b/c" to create a new module
in "c". This also simplifies description of "relative URL" as there is now
exactly *one* form: a URL relative to the parent's origin repo.

Fix rev-list when showing objects involving submodules

The function mark_tree_uninteresting() assumed that the tree entries
are blob when they are not trees.  This is not so.  Since we do
not traverse into submodules (yet), the gitlinks should be ignored.

In general, we should try to start moving away from using the
"S_ISLNK()" like things for internal git state. It was a mistake to
just assume the numbers all were same across all systems in the first
place.  This implementation converts to the "object_type", and then
uses a case statement.
