A reference to the .repo/ tree in repo client checkouts. Hopefully it's complete & up-to-date, but who knows!
All content under .repo/ is managed by repo itself with few exceptions.
In general, you should not make manual changes in here. If a setting was initialized using an option to repo init, you should use that command to change the setting later on. It is always safe to re-run repo init in existing repo client checkouts. For example, if you want to change the manifest branch, you can simply run repo init --manifest-branch=<new name> and repo will take care of the rest.
config: Per-repo client checkout settings using git-config file format..repo_config.json: JSON cache of the config file for repo to read/process quickly.repo/: A git checkout of the repo project. This is how repo re-execs itself to get the latest released version.
It tracks the git repository at REPO_URL using the REPO_REV branch. Those are specified at repo init time using the --repo-url=<REPO_URL> and --repo-rev=<REPO_REV> options.
Any changes made to this directory will usually be automatically discarded by repo itself when it checks for updates. If you want to update to the latest version of repo, use repo selfupdate instead. If you want to change the git URL/branch that this tracks, re-run repo init with the new settings.
.repo_fetchtimes.json: Used by repo sync to record stats when syncing the various projects.
For more documentation on the manifest format, including the local_manifests support, see the manifest-format.md file.
manifests/: A git checkout of the manifest project. Its .git/ state points to the manifest.git bare checkout (see below). It tracks the git branch specified at repo init time via --manifest-branch.
The local branch name is always default regardless of the remote tracking branch. Do not get confused if the remote branch is not default, or if there is a remote default that is completely different!
No manual changes should be made in here as it will just confuse repo and it won't automatically recover causing no new changes to be picked up.
manifests.git/: A bare checkout of the manifest project. It tracks the git repository specified at repo init time via --manifest-url.
No manual changes should be made in here as it will just confuse repo. If you want to switch the tracking settings, re-run repo init with the new settings.
manifest.xml: The manifest that repo uses. It is generated at repo init and uses the --manifest-name to determine what manifest file to load next out of manifests/.
Do not try to modify this to load other manifests as it will confuse repo. If you want to switch manifest files, re-run repo init with the new setting.
Older versions of repo managed this with symlinks.
manifest.xml -> manifests/<manifest-name>.xml: A symlink to the manifest that the user wishes to sync. It is specified at repo init time via --manifest-name.
manifests.git/.repo_config.json: JSON cache of the manifests.git/config file for repo to read/process quickly.
local_manifest.xml (Deprecated): User-authored tweaks to the manifest used to sync. See local manifests for more details.
local_manifests/: Directory of user-authored manifest fragments to tweak the manifest used to sync. See local manifests for more details.
Warning: Please do not use repo's approach to projects/ & project-objects/ layouts as a model for other tools to implement similar approaches. It has a number of known downsides like:
gc or prune which may lead to data loss or corruption (since those operate on leaf projects and miss refs in other leaves). See https://gerrit-review.googlesource.com/c/git-repo/+/254392 for more details.Instead, you should use standard Git workflows like git worktree or gitsubmodules with superprojects.
copy-link-files.json: Tracking file used by repo sync to determine when copyfile or linkfile are added or removed and need corresponding updates.
project.list: Tracking file used by repo sync to determine when projects are added or removed and need corresponding updates in the checkout.
projects/: Bare checkouts of every project synced by the manifest. The filesystem layout matches the <project path=... setting in the manifest (i.e. where it's checked out in the repo client source tree). Those checkouts will symlink their .git/ state to paths under here.
Some git state is further split out under project-objects/.
project-objects/: Git objects that are safe to share across multiple git checkouts. The filesystem layout matches the <project name=... setting in the manifest (i.e. the path on the remote server) with a .git suffix. This allows for multiple checkouts of the same remote git repo to share their objects. For example, you could have different branches of foo/bar.git checked out to foo/bar-main, foo/bar-release, etc... There will be multiple trees under projects/ for each one, but only one under project-objects/.
This layout is designed to allow people to sync against different remotes (e.g. a local mirror & a public review server) while avoiding duplicating the content. However, this can run into problems if different remotes use the same path on their respective servers. Best to avoid that.
subprojects/: Like projects/, but for git submodules.
subproject-objects/: Like project-objects/, but for git submodules.
worktrees/: Bare checkouts of every project synced by the manifest. The filesystem layout matches the <project name=... setting in the manifest (i.e. the path on the remote server) with a .git suffix. This has the same advantages as the project-objects/ layout above.
This is used when git worktree's are enabled.
The .repo/manifests.git/config file is used to track settings for the entire repo client checkout.
Most settings use the [repo] section to avoid conflicts with git.
Everything under [repo.syncstate.*] is used to keep track of sync details for logging purposes.
User controlled settings are initialized when running repo init.
| Setting | repo init Option | Use/Meaning |
|---|---|---|
| manifest.groups | --groups & --platform | The manifest groups to sync |
| repo.archive | --archive | Use git archive for checkouts |
| repo.clonebundle | --clone-bundle | Whether the initial sync used clone.bundle explicitly |
| repo.clonefilter | --clone-filter | Filter setting when using partial git clones |
| repo.depth | --depth | Create shallow checkouts when cloning |
| repo.dissociate | --dissociate | Dissociate from any reference/mirrors after initial clone |
| repo.mirror | --mirror | Checkout is a repo mirror |
| repo.partialclone | --partial-clone | Create partial git clones |
| repo.partialcloneexclude | --partial-clone-exclude | Comma-delimited list of project names (not paths) to exclude while using partial git clones |
| repo.reference | --reference | Reference repo client checkout |
| repo.submodules | --submodules | Sync git submodules |
| repo.superproject | --use-superproject | Sync superproject |
| repo.worktree | --worktree | Use git worktree for checkouts |
| user.email | --config-name | User's e-mail address; Copied into .git/config when checking out a new project |
| user.name | --config-name | User's name; Copied into .git/config when checking out a new project |
For more details on this feature, see the repo-hooks docs. We'll just discuss the internal configuration settings. These are stored in the registered <repo-hooks> project itself, so if the manifest switches to a different project, the settings will not be copied.
| Setting | Use/Meaning |
|---|---|
| repo.hooks.<hook>.approvedmanifest | User approval for secure manifest sources (e.g. https://) |
| repo.hooks.<hook>.approvedhash | User approval for insecure manifest sources (e.g. http://) |
For example, if our manifest had the following entries, we would store settings under .repo/projects/src/repohooks.git/config (which would be reachable via git --git-dir=src/repohooks/.git config).
<project path="src/repohooks" name="chromiumos/repohooks" ... /> <repo-hooks in-project="chromiumos/repohooks" ... />
If <hook> is pre-upload, the .git/config setting might be:
[repo "hooks.pre-upload"] approvedmanifest = https://chromium.googlesource.com/chromiumos/manifest
These settings are somewhat meant to be tweaked by the user on a per-project basis (e.g. git config in a checked out source repo).
Where possible, we re-use standard git settings to avoid confusion, and we refrain from documenting those, so see git-config documentation instead.
See repo help upload for documentation on [review] settings.
The [remote] settings are automatically populated/updated from the manifest.
The [branch] settings are updated by repo start and git branch.
| Setting | Subcommands | Use/Meaning |
|---|---|---|
| review.<url>.autocopy | upload | Automatically add to --cc=<value> |
| review.<url>.autoreviewer | upload | Automatically add to --reviewers=<value> |

Repo will create & maintain a few files in the user's home directory.
.repoconfig/: Repo's per-user directory for all random config files/state.
.repoconfig/config: Per-user settings using git-config file format.
.repoconfig/keyring-version: Cache file for checking if the gnupg subdir has all the same keys as the repo launcher. Used to avoid running gpg constantly as that can be quite slow.
.repoconfig/gnupg/: GnuPG‘s internal state directory used when repo needs to run gpg. This provides isolation from the user’s normal ~/.gnupg/.
.repoconfig/.repo_config.json: JSON cache of the .repoconfig/config file for repo to read/process quickly.
.repo_.gitconfig.json: JSON cache of the .gitconfig file for repo to read/process quickly.
