You may find these things in your git repository (
directory for a repository associated with your working tree, or
<project>.git directory for a public bare repository. It is
also possible to have a working tree where
.git is a plain
ascii file containing
gitdir: <path>, i.e. the path to the
real git repository).
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 couple of ways to violate it.
You could populate the repository by running a commit walker without
-aoption. Depending on which options are given, you could have only commit objects without associated blobs and trees this way, for example. A repository with this kind of incomplete object store is not suitable to be published to the outside world but sometimes useful for private repository.
You also could have an incomplete but locally usable repository by cloning shallowly. See git-clone.
You can be using
$GIT_ALTERNATE_OBJECT_DIRECTORIESmechanism 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/alternatespoints at the right object stores it borrows from.
Traditionally, each object is stored in its own file. They are split into 256 subdirectories using the first two letters from its object name to keep the number of directory entries
objectsdirectory itself needs to hold. Objects found here are often called unpacked (or loose) objects.
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.
Additional information about the object store is recorded in this directory.
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-infoshould be run to keep this file up-to-date if the repository is published for dumb transports. git-repack does this by default.
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.
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.
References are stored in subdirectories of this directory. The git-prune command knows to keep objects reachable from refs found in this directory and its subdirectories.
records tip-of-the-tree commit objects of branch
records any object name (not necessarily a commit object, or a tag object that points at a commit object).
records tip-of-the-tree commit objects of branches copied from a remote repository.
records the same information as refs/heads/, refs/tags/, and friends record in a more efficient way. See git-pack-refs.
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, and almost all commands work identically as normal. See git-checkout for details.
A slightly deprecated way to store shorthands to be used to specify URL to git-fetch, git-pull and git-push commands is to store a file in
branches/<name>and give name to these commands in place of repository argument.
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, they need to be made executable. Read githooks for more details about each hook.
The current index file for the repository. It is usually not found in a bare repository.
Additional information about the repository is recorded in this directory.
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/updatehook, which is run by the git-receive-pack command when you git-push into the repository.
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.
This file, by convention among Porcelains, stores the exclude pattern list.
.gitignoreis 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: gitignore.
Stores shorthands to be used to give URL and default refnames to interact with remote repository to git-fetch, git-pull and git-push commands.
Records of changes made to refs are stored in this directory. See git-update-ref for more information.
Records all changes made to the branch tip named
Records all changes made to the tag named
Part of the git suite.
