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 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' - 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 absolute filesystem paths of alternate - object stores that this object store borrows objects - from, one pathname per line. - -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). - -HEAD:: - A symlink of the form `refs/heads/'name'` to point at - the current branch, if exists. 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 such a symlink here. It is legal if the - named branch 'name' does not (yet) exist. - -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-db` is run, but all of them are disabled by - default. To enable, they need to be made executable. - -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 is to help dumb transports to discover what - refs are available in this repository. Whenever you - create/delete a new branch or a new tag, `git - update-server-info` should be run to keep this file - up-to-date if the repository is published for dumb - transports. The `git-receive-pack` command, which is - run on a remote repository when you `git push` into it, - runs `hooks/update` hook to help you achieve this. - -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. `git status` looks at it, but - otherwise it is not looked at by any of the core git - commands. - -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. |
