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.

git-submodule summary: show commit summary This patch does the hard work to show submodule commit summary. For a modified submodule, a series of commits will be shown with the following command: git log --pretty='format:%m %s' \ --first-parent sha1_src...sha1_dst where the sha1_src is from the given super project commit and the sha1_dst is from the index or working tree (switched by --cached). For a deleted, added, or typechanged (blob<->submodule) submodule, only one single newest commit from the existing end (for example, src end for submodule deleted or type changed from submodule to blob) will be shown. If the src/dst sha1 for a submodule is missing in the submodule directory, a warning will be issued except in two cases where the submodule directory is deleted (type 'D') or typechanged to blob (one case of type 'T'). In the title line for a submodule, the src/dst sha1 and the number of commits (--first-parent) between the two commits will be shown. The following example demonstrates most cases. Example: commit summary for modified submodules sm1-sm5. -------------------------------------------- $ git submodule summary * sm1 354cd45...3f751e5 (4): < one line message for C < one line message for B > one line message for D > one line message for E * sm2 5c8bfb5...000000 (3): < one line message for F * sm3 354cd45...3f751e5: Warn: sm3 doesn't contain commit 354cd45 * sm4 354cd34(submodule)-> 235efa(blob) (1): < one line message for G * sm5 354cd34(blob)-> 235efa(submodule) (5): > one line message for H -------------------------------------------- Signed-off-by: Ping Yin <pkufranky@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

If the src/dst sha1 for a submodule is missing in the submodule directory, a warning will be issued except in two cases where the submodule directory is deleted (type 'D') or typechanged to blob (one case of type 'T'). In the title line for a submodule, the src/dst sha1 and the number of commits (--first-parent) between the two commits will be shown. The following example demonstrates most cases. Example: commit summary for modified submodules sm1-sm5. -------------------------------------------- $ git submodule summary * sm1 354cd45...3f751e5 (4): < one line message for C < one line message for B > one line message for D > one line message for E * sm2 5c8bfb5...000000 (3): < one line message for F * sm3 354cd45...3f751e5: Warn: sm3 doesn't contain commit 354cd45 * sm4 354cd34(submodule)-> 235efa(blob) (1): < one line message for G * sm5 354cd34(blob)-> 235efa(submodule) (5): > one line message for H -------------------------------------------- Signed-off-by: Ping Yin <pkufranky@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

git-submodule summary: show commit summary This patch does the hard work to show submodule commit summary. For a modified submodule, a series of commits will be shown with the following command: git log --pretty='format:%m %s' \ --first-parent sha1_src...sha1_dst where the sha1_src is from the given super project commit and the sha1_dst is from the index or working tree (switched by --cached). For a deleted, added, or typechanged (blob<->submodule) submodule, only one single newest commit from the existing end (for example, src end for submodule deleted or type changed from submodule to blob) will be shown. If the src/dst sha1 for a submodule is missing in the submodule directory, a warning will be issued except in two cases where the submodule directory is deleted (type 'D') or typechanged to blob (one case of type 'T').
