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 gitlink: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 - gitlink: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 gitlink: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: gitlink: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.
