git repository layout |
|
===================== |
|
|
|
You may find these things in your git repository (`.git` |
|
directory for a repository associated with your working tree, or |
|
`'project'.git` directory for a public 'bare' 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 couple of ways to violate |
|
it. |
|
+ |
|
. You could populate the repository by running a commit walker |
|
without `-a` option. 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 linkgit:git-clone[1]. |
|
. You can be using `objects/info/alternates` mechanism, or |
|
`$GIT_ALTERNATE_OBJECT_DIRECTORIES` mechanism 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 right object stores |
|
it borrows from. |
|
|
|
objects/[0-9a-f][0-9a-f]:: |
|
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 `objects` directory itself needs to |
|
hold. 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 keep |
|
objects reachable from refs found in this directory and |
|
its subdirectories. |
|
|
|
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. |
|
|
|
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]. |
|
|
|
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', and almost all commands work |
|
identically as normal. See linkgit:git-checkout[1] for |
|
details. |
|
|
|
branches:: |
|
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:: |
|
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 link:hooks.html[hooks] for more details about |
|
each hook. |
|
|
|
index:: |
|
The current index file for the repository. It is |
|
usually not found in a bare repository. |
|
|
|
info:: |
|
Additional information about the repository is recorded |
|
in this directory. |
|
|
|
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. |
|
|
|
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]. |
|
|
|
remotes:: |
|
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. |
|
|
|
logs:: |
|
Records of changes made to refs are stored in this |
|
directory. See the documentation on git-update-ref |
|
for more information. |
|
|
|
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].
