git-submodule.sh - Remove trailing / from URL if found git clone does not complain if a trailing '/' is included in the origin URL, but doing so causes resolution of a submodule's URL relative to the superproject to fail. Trailing /'s are likely when cloning locally using tab-completion, so the slash may appear in either superproject or submodule URL. So, ignore the trailing slash if it already exists in the superproject's URL, and don't record one for the submodule (which could itself have submodules...). The problem I'm trying to fix is that a number of folks have superprojects checked out where the recorded origin URL has a trailing /, and a submodule has its origin in a directory sitting right next to the superproject on the server. Thus, we have: superproject url = server:/public/super submodoule url = server:/public/sub1 However, in the checked out superproject's .git/config [remote "origin"] url = server:/public/super/ and for similar reasons, the submodule has its URL recorded in .gitmodules as [submodule "sub"] path = submodule1 url = ../sub1/ resolve_relative_url gets the submodule's recorded url as $1, which the caller retrieved from .gitmodules, and retrieves the superprojects origin from .git/config. So in this case resolve_relative_url has that: url = ../sub1/ remoteurl = server:/public/super/ So, without any patch, resolve_relative_url computes the submodule's URL as: server:/public/super/sub1/ rather than server:/public/sub1 In summary, it is essential that resolve_relative_url strip the trailing / from the superproject's url before starting, and beneficial if it assures that the result does not contain a trailing / as the submodule may itself also be a superproject.

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: add submodules with git add -f <path> Change `git submodule add' to add the new submodule <path> with `git add --force'. I keep my /etc in .git with a .gitignore that contains just "*". I.e. `git status' will ignore everything that isn't in the tree already. When I do: git submodule add <url> hlagh git-submodule will get as far as checking out the remote repository into hlagh, but it'll die right afterwards when it fails to add the new path: The following paths are ignored by one of your .gitignore files: hlagh Use -f if you really want to add them. fatal: no files added Failed to add submodule 'hlagh' Currently there's no way to add a submodule in this situation other than to remove the ignored path from the .gitignore while I'm at it. That's silly, when you run `git submodule add' you're explicitly saying that you want to add something *new* to the repository. Instead it should just add the path with `git add --force'. Initially I implemented this by adding new -f and --force options to `git submodule add'. But if the --force option isn't supplied it'll get as far as cloning `hlagh', but won't add it. So the first thing the user has to do is to remove `hlagh' and then try again with the --force option. That sucks, it should just add the path to begin with. I can't think of any usecase where you've gone through the trouble of typing out `git submodule add ..', but wish to be overriden by a `gitignore'. The submodule semantics should be more like `git init', not `git add'. Signed-off-by: Ævar Arnfjörð Bjarmason <avarab@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

git-submodule foreach: Add $toplevel variable Add a $toplevel variable accessible to `git submodule foreach`, it contains the absolute path of the top level directory (where .gitmodules is). This makes it possible to e.g. read data in .gitmodules from within foreach commands. I'm using this to configure the branch names I want to track for each submodule: git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull' For a little history: This patch is borne out of my continuing fight of trying to have Git track the branches of submodules, not just their commits. Obviously that's not how they work (they only track commits), but I'm just interested in being able to do: git submodule foreach 'git pull' Of course that won't work because the submodule is in a disconnected head, so I first have to connect it, but connect it *to what*. For a while I was happy with this because as fate had it, it just so happened to do what I meant: git submodule foreach 'git checkout $(git describe --all --always) && git pull' But then that broke down, if there's a tag and a branch the tag will win out, and I can't git pull a branch: $ git branch -a * master remotes/origin/HEAD -> origin/master remotes/origin/master $ git tag -l release-0.0.6 $ git describe --always --all release-0.0.6 So I figured that I might as well start tracking the branches I want in .gitmodules itself: [submodule "yaml-mode"] path = yaml-mode url = git://github.com/yoshiki/yaml-mode.git branch = master So now I can just do (as stated above): git submodule foreach 'git checkout $(git config --file $toplevel/.gitmodules submodule.$name.branch) && git pull' Maybe there's a less painful way to do *that* (I'd love to hear about it). But regardless of that I think it's a good idea to be able to know what the top-level is from git submodule foreach.

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>
