This mechanism is often used for -a working tree of a submodule checkout, to allow you in the -containing superproject to `git checkout` a branch that does not -have the submodule. The `checkout` has to remove the entire -submodule working tree, without losing the submodule repository. - -These things may exist in a Git repository. - -objects:: - Object store associated with this repository. Usually - an object store is self sufficient (i.e. all the objects - that are referred to by an object found in it are also - found in it), but there are a few ways to violate it. -+ -. You could have an incomplete but locally usable repository -by creating a shallow clone. See linkgit:git-clone[1]. -. You could be using the `objects/info/alternates` or -`$GIT_ALTERNATE_OBJECT_DIRECTORIES` mechanisms to 'borrow' -objects from other object stores. A repository with this kind -of incomplete object store is not suitable to be published for -use with dumb transports but otherwise is OK as long as -`objects/info/alternates` points at the object stores it -borrows from. -+ -This directory is ignored if $GIT_COMMON_DIR is set and -"$GIT_COMMON_DIR/objects" will be used instead. - -objects/[0-9a-f][0-9a-f]:: - A newly created object is stored in its own file. - The objects are splayed over 256 subdirectories using - the first two characters of the sha1 object name to - keep the number of directory entries in `objects` - itself to a manageable number. Objects found - here are often called 'unpacked' (or 'loose') objects. - -objects/pack:: - Packs (files that store many object in compressed form, - along with index files to allow them to be randomly - accessed) are found in this directory. - -objects/info:: - Additional information about the object store is - recorded in this directory. - -objects/info/packs:: - This file is to help dumb transports discover what packs - are available in this object store. Whenever a pack is - added or removed, `git update-server-info` should be run - to keep this file up to date if the repository is - published for dumb transports. 'git repack' does this - by default. - -objects/info/alternates:: - This file records paths to alternate object stores that - this object store borrows objects from, one pathname per - line. Note that not only native Git tools use it locally, - but the HTTP fetcher also tries to use it remotely; this - will usually work if you have relative paths (relative - to the object database, not to the repository!) in your - alternates file, but it will not work if you use absolute - paths unless the absolute path in filesystem and web URL - is the same. See also `objects/info/http-alternates`. - -objects/info/http-alternates:: - This file records URLs to alternate object stores that - this object store borrows objects from, to be used when - the repository is fetched over HTTP. - -refs:: - References are stored in subdirectories of this - directory. The 'git prune' command knows to preserve - objects reachable from refs found in this directory and - its subdirectories. - This directory is ignored (except refs/bisect and - refs/worktree) if $GIT_COMMON_DIR is set and - "$GIT_COMMON_DIR/refs" will be used instead. - -refs/heads/`name`:: - records tip-of-the-tree commit objects of branch `name` - -refs/tags/`name`:: - records any object name (not necessarily a commit - object, or a tag object that points at a commit object). - -refs/remotes/`name`:: - records tip-of-the-tree commit objects of branches copied - from a remote repository. - -refs/replace/`<obj-sha1>`:: - records the SHA-1 of the object that replaces `<obj-sha1>`. - This is similar to info/grafts and is internally used and - maintained by linkgit:git-replace[1]. Such refs can be exchanged - between repositories while grafts are not. - -packed-refs:: - records the same information as refs/heads/, refs/tags/, - and friends record in a more efficient way. See - linkgit:git-pack-refs[1]. This file is ignored if $GIT_COMMON_DIR - is set and "$GIT_COMMON_DIR/packed-refs" will be used instead. - -HEAD:: - A symref (see glossary) to the `refs/heads/` namespace - describing the currently active branch. It does not mean - much if the repository is not associated with any working tree - (i.e. a 'bare' repository), but a valid Git repository - *must* have the HEAD file; some porcelains may use it to - guess the designated "default" branch of the repository - (usually 'master'). It is legal if the named branch - 'name' does not (yet) exist. In some legacy setups, it is - a symbolic link instead of a symref that points at the current - branch. -+ -HEAD can also record a specific commit directly, instead of -being a symref to point at the current branch. Such a state -is often called 'detached HEAD.' See linkgit:git-checkout[1] -for details. - -config:: - Repository specific configuration file. This file is ignored - if $GIT_COMMON_DIR is set and "$GIT_COMMON_DIR/config" will be - used instead. - -config.worktree:: - Working directory specific configuration file for the main - working directory in multiple working directory setup (see - linkgit:git-worktree[1]). - -branches:: - A slightly deprecated way to store shorthands to be used - to specify a URL to 'git fetch', 'git pull' and 'git push'. - A file can be stored as `branches/<name>` and then - 'name' can be given to these commands in place of - 'repository' argument. See the REMOTES section in - linkgit:git-fetch[1] for details. This mechanism is legacy - and not likely to be found in modern repositories. This - directory is ignored if $GIT_COMMON_DIR is set and - "$GIT_COMMON_DIR/branches" will be used instead. - - -hooks:: - Hooks are customization scripts used by various Git - commands. A handful of sample hooks are installed when - 'git init' is run, but all of them are disabled by - default. To enable, the `.sample` suffix has to be - removed from the filename by renaming. - Read linkgit:githooks[5] for more details about - each hook. This directory is ignored if $GIT_COMMON_DIR is set - and "$GIT_COMMON_DIR/hooks" will be used instead. - -common:: - When multiple working trees are used, most of files in - $GIT_DIR are per-worktree with a few known exceptions. All - files under 'common' however will be shared between all - working trees. - -index:: - The current index file for the repository. It is - usually not found in a bare repository. - -sharedindex.<SHA-1>:: - The shared index part, to be referenced by $GIT_DIR/index and - other temporary index files. Only valid in split index mode. - -info:: - Additional information about the repository is recorded - in this directory. This directory is ignored if $GIT_COMMON_DIR - is set and "$GIT_COMMON_DIR/info" will be used instead. - -info/refs:: - This file helps dumb transports discover what refs are - available in this repository. If the repository is - published for dumb transports, this file should be - regenerated by 'git update-server-info' every time a tag - or branch is created or modified. This is normally done - from the `hooks/update` hook, which is run by the - 'git-receive-pack' command when you 'git push' into the - repository. - -info/grafts:: - This file records fake commit ancestry information, to - pretend the set of parents a commit has is different - from how the commit was actually created. One record - per line describes a commit and its fake parents by - listing their 40-byte hexadecimal object names separated - by a space and terminated by a newline. -+ -Note that the grafts mechanism is outdated and can lead to problems -transferring objects between repositories; see linkgit:git-replace[1] -for a more flexible and robust system to do the same thing. - -info/exclude:: - This file, by convention among Porcelains, stores the - exclude pattern list. `.gitignore` is the per-directory - ignore file. 'git status', 'git add', 'git rm' and - 'git clean' look at it but the core Git commands do not look - at it. See also: linkgit:gitignore[5]. - -info/attributes:: - Defines which attributes to assign to a path, similar to per-directory - `.gitattributes` files. See also: linkgit:gitattributes[5]. - -info/sparse-checkout:: - This file stores sparse checkout patterns. - See also: linkgit:git-read-tree[1]. - -remotes:: - Stores shorthands for URL and default refnames for use - when interacting with remote repositories via 'git fetch', - 'git pull' and 'git push' commands. See the REMOTES section - in linkgit:git-fetch[1] for details. This mechanism is legacy - and not likely to be found in modern repositories. This - directory is ignored if $GIT_COMMON_DIR is set and - "$GIT_COMMON_DIR/remotes" will be used instead. - -logs:: - Records of changes made to refs are stored in this directory. - See linkgit:git-update-ref[1] for more information. This - directory is ignored if $GIT_COMMON_DIR is set and - "$GIT_COMMON_DIR/logs" will be used instead. - -logs/refs/heads/`name`:: - Records all changes made to the branch tip named `name`. - -logs/refs/tags/`name`:: - Records all changes made to the tag named `name`. - -shallow:: - This is similar to `info/grafts` but is internally used - and maintained by shallow clone mechanism. See `--depth` - option to linkgit:git-clone[1] and linkgit:git-fetch[1]. This - file is ignored if $GIT_COMMON_DIR is set and - "$GIT_COMMON_DIR/shallow" will be used instead. - -commondir:: - If this file exists, $GIT_COMMON_DIR (see linkgit:git[1]) will - be set to the path specified in this file if it is not - explicitly set. If the specified path is relative, it is - relative to $GIT_DIR. The repository with commondir is - incomplete without the repository pointed by "commondir". - -modules:: - Contains the git-repositories of the submodules. - -worktrees:: - Contains administrative data for linked - working trees. Each subdirectory contains the working tree-related - part of a linked working tree. This directory is ignored if - $GIT_COMMON_DIR is set, in which case - "$GIT_COMMON_DIR/worktrees" will be used instead. - -worktrees/<id>/gitdir:: - A text file containing the absolute path back to the .git file - that points to here. This is used to check if the linked - repository has been manually removed and there is no need to - keep this directory any more. The mtime of this file should be - updated every time the linked repository is accessed. - -worktrees/<id>/locked:: - If this file exists, the linked working tree may be on a - portable device and not available. The presence of this file - prevents `worktrees/<id>` from being pruned either automatically - or manually by `git worktree prune`. The file may contain a string - explaining why the repository is locked. - -worktrees/<id>/config.worktree:: - Working directory specific configuration file. - -include::technical/repository-version.txt[] - -SEE ALSO --------- -linkgit:git-init[1], -linkgit:git-clone[1], -linkgit:git-fetch[1], -linkgit:git-pack-refs[1], -linkgit:git-gc[1], -linkgit:git-checkout[1], -linkgit:gitglossary[7], -link:user-manual.html[The Git User's Manual] - -GIT ---- -Part of the linkgit:git[1] suite |
