DETAILS
The 'repo sync' command synchronizes local project directories with the remote
repositories specified in the manifest. If a local project does not yet exist, it will
clone a new local directory from the remote repository and set up tracking branches as
specified in the manifest. If the local project already exists, 'repo sync' will update
the remote branches and rebase any new local changes on top of the new remote changes.
'repo sync' will synchronize all projects listed at the command line. Projects can be
specified either by name, or by a relative or absolute path to the project's local
directory. If no projects are specified, 'repo sync' will synchronize all projects listed
in the manifest.
The -d/--detach option can be used to switch specified projects back to the manifest
revision. This option is especially helpful if the project is currently on a topic branch,
but the manifest revision is temporarily needed.
The -s/--smart-sync option can be used to sync to a known good build as specified by the
manifest-server element in the current manifest. The -t/--smart-tag option is similar and
allows you to specify a custom tag/label.
The -u/--manifest-server-username and -p/--manifest-server-password options can be used to
specify a username and password to authenticate with the manifest server when using the -s
or -t option.
If -u and -p are not specified when using the -s or -t option, 'repo sync' will attempt to
read authentication credentials for the manifest server from the user's .netrc file.
'repo sync' will not use authentication credentials from -u/-p or .netrc if the manifest
server specified in the manifest file already includes credentials.
By default, all projects will be synced. The --fail-fast option can be used to halt
syncing as soon as possible when the first project fails to sync.
The --force-sync option can be used to overwrite existing git directories if they have
previously been linked to a different object directory. WARNING: This may cause data to be
lost since refs may be removed when overwriting.
The --force-remove-dirty option can be used to remove previously used projects with
uncommitted changes. WARNING: This may cause data to be lost since uncommitted changes may
be removed with projects that no longer exist in the manifest.
The --no-clone-bundle option disables any attempt to use $URL/clone.bundle to bootstrap a
new Git repository from a resumeable bundle file on a content delivery network. This may
be necessary if there are problems with the local Python HTTP client or proxy
configuration, but the Git binary works.
The --fetch-submodules option enables fetching Git submodules of a project from server.
The -c/--current-branch option can be used to only fetch objects that are on the branch
specified by a project's revision.
The --optimized-fetch option can be used to only fetch projects that are fixed to a sha1
revision if the sha1 revision does not already exist locally.
The --prune option can be used to remove any refs that no longer exist on the remote.
SSH Connections
If at least one project remote URL uses an SSH connection (ssh://, git+ssh://, or
user@host:path syntax) repo will automatically enable the SSH ControlMaster option when
connecting to that host. This feature permits other projects in the same 'repo sync'
session to reuse the same SSH tunnel, saving connection setup overheads.
To disable this behavior on UNIX platforms, set the GIT_SSH environment variable to 'ssh'.
For example:
export GIT_SSH=ssh repo sync
Compatibility
This feature is automatically disabled on Windows, due to the lack of UNIX domain socket
support.
This feature is not compatible with url.insteadof rewrites in the user's ~/.gitconfig.
'repo sync' is currently not able to perform the rewrite early enough to establish the
ControlMaster tunnel.
If the remote SSH daemon is Gerrit Code Review, version 2.0.10 or later is required to fix
a server side protocol bug.
