Using another project while maintaining independent history. + Submodules allow you to contain the working tree of another project + within your own working tree while keeping the history of both + projects separate. Also, since submodules are fixed to an arbitrary + version, the other project can be independently developed without + affecting the superproject, allowing the superproject project to + fix itself to new versions only when desired. + +2. Splitting a (logically single) project into multiple + repositories and tying them back together. This can be used to + overcome current limitations of Gits implementation to have + finer grained access: + + * Size of the git repository: + In its current form Git scales up poorly for large repositories containing + content that is not compressed by delta computation between trees. + However you can also use submodules to e.g. hold large binary assets + and these repositories are then shallowly cloned such that you do not + have a large history locally. + * Transfer size: + In its current form Git requires the whole working tree present. It + does not allow partial trees to be transferred in fetch or clone. + * Access control: + By restricting user access to submodules, this can be used to implement + read/write policies for different users. + +The configuration of submodules +------------------------------- + +Submodule operations can be configured using the following mechanisms +(from highest to lowest precedence): + + * The command line for those commands that support taking submodule specs. + Most commands have a boolean flag '--recurse-submodules' whether to + recurse into submodules. Examples are `ls-files` or `checkout`. + Some commands take enums, such as `fetch` and `push`, where you can + specify how submodules are affected. + + * The configuration inside the submodule. This includes `$GIT_DIR/config` + in the submodule, but also settings in the tree such as a `.gitattributes` + or `.gitignore` files that specify behavior of commands inside the + submodule. ++ +For example an effect from the submodule's `.gitignore` file +would be observed when you run `git status --ignore-submodules=none` in +the superproject. This collects information from the submodule's working +directory by running `status` in the submodule, which does pay attention +to its `.gitignore` file. ++ +The submodule's `$GIT_DIR/config` file would come into play when running +`git push --recurse-submodules=check` in the superproject, as this would +check if the submodule has any changes not published to any remote. The +remotes are configured in the submodule as usual in the `$GIT_DIR/config` +file. + + * The configuration file `$GIT_DIR/config` in the superproject. + Typical configuration at this place is controlling if a submodule + is recursed into at all via the `active` flag for example. ++ +If the submodule is not yet initialized, then the configuration +inside the submodule does not exist yet, so configuration where to +obtain the submodule from is configured here for example. + + * the `.gitmodules` file inside the superproject. Additionally to the + required mapping between submodule's name and path, a project usually + uses this file to suggest defaults for the upstream collection + of repositories. ++ +This file mainly serves as the mapping between name and path in +the superproject, such that the submodule's git directory can be +located. ++ +If the submodule has never been initialized, this is the only place +where submodule configuration is found. It serves as the last fallback +to specify where to obtain the submodule from. + +FORMS +----- + +Submodules can take the following forms: + + * The basic form described in DESCRIPTION with a Git directory, +a working directory, a `gitlink`, and a `.gitmodules` entry. + + * "Old-form" submodule: A working directory with an embedded +`.git` directory, and the tracking `gitlink` and `.gitmodules` entry in +the superproject. This is typically found in repositories generated +using older versions of Git. ++ +It is possible to construct these old form repositories manually. ++ +When deinitialized or deleted (see below), the submodule’s Git +directory is automatically moved to `$GIT_DIR/modules/<name>/` +of the superproject. + + * Deinitialized submodule: A `gitlink`, and a `.gitmodules` entry, +but no submodule working directory. The submodule’s git directory +may be there as after deinitializing the git directory is kept around. +The directory which is supposed to be the working directory is empty instead. ++ +A submodule can be deinitialized by running `git submodule deinit`. +Besides emptying the working directory, this command only modifies +the superproject’s `$GIT_DIR/config` file, so the superproject’s history +is not affected. This can be undone using `git submodule init`. + + * Deleted submodule: A submodule can be deleted by running +`git rm <submodule path> && git commit`. This can be undone +using `git revert`. ++ +The deletion removes the superproject’s tracking data, which are +both the `gitlink` entry and the section in the `.gitmodules` file. +The submodule’s working directory is removed from the file +system, but the Git directory is kept around as it to make it +possible to checkout past commits without requiring fetching +from another repository. ++ +To completely remove a submodule, manually delete +`$GIT_DIR/modules/<name>/`. + +Workflow for a third party library +---------------------------------- + + # add a submodule + git submodule add <url> <path> + + # occasionally update the submodule to a new version: + git -C <path> checkout <new version> + git add <path> + git commit -m "update submodule to new version" + + # See the list of submodules in a superproject + git submodule status + + # See FORMS on removing submodules + + +Workflow for an artificially split repo +-------------------------------------- + + # Enable recursion for relevant commands, such that + # regular commands recurse into submodules by default + git config --global submodule.recurse true + + # Unlike the other commands below clone still needs + # its own recurse flag: + git clone --recurse <URL> <directory> + cd <directory> + + # Get to know the code: + git grep foo + git ls-files + + # Get new code + git fetch + git pull --rebase + + # change worktree + git checkout + git reset + +Implementation details +---------------------- + +When cloning or pulling a repository containing submodules the submodules +will not be checked out by default; You can instruct 'clone' to recurse +into submodules.
