.SH DETAILS
.PP
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.
.PP
\&'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.
.PP
The \fB\-d\fR/\-\-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.
.PP
The \fB\-s\fR/\-\-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
\fB\-t\fR/\-\-smart\-tag option is similar and allows you to specify a custom tag/label.
.PP
The \fB\-u\fR/\-\-manifest\-server\-username and \fB\-p\fR/\-\-manifest\-server\-password options can
be used to specify a username and password to authenticate with the manifest
server when using the \fB\-s\fR or \fB\-t\fR option.
.PP
If \fB\-u\fR and \fB\-p\fR are not specified when using the \fB\-s\fR or \fB\-t\fR option, 'repo sync' will
attempt to read authentication credentials for the manifest server from the
user's .netrc file.
.PP
\&'repo sync' will not use authentication credentials from \fB\-u\fR/\-p or .netrc if the
manifest server specified in the manifest file already includes credentials.
.PP
By default, all projects will be synced. The \fB\-\-fail\-fast\fR option can be used to
halt syncing as soon as possible when the first project fails to sync.
.PP
The \fB\-\-force\-sync\fR 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.
.PP
The \fB\-\-force\-remove\-dirty\fR 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.
.PP
The \fB\-\-no\-clone\-bundle\fR option disables any attempt to use \fI\,$URL/clone.bundle\/\fP 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.
.PP
The \fB\-\-fetch\-submodules\fR option enables fetching Git submodules of a project from
server.
.PP
The \fB\-c\fR/\-\-current\-branch option can be used to only fetch objects that are on the
branch specified by a project's revision.
.PP
The \fB\-\-optimized\-fetch\fR option can be used to only fetch projects that are fixed
to a sha1 revision if the sha1 revision does not already exist locally.
.PP
The \fB\-\-prune\fR option can be used to remove any refs that no longer exist on the
remote.
.PP
SSH Connections
.PP
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.
.PP
To disable this behavior on UNIX platforms, set the GIT_SSH environment variable
to 'ssh'. For example:
.IP
export GIT_SSH=ssh
repo sync
.PP
Compatibility
.PP
This feature is automatically disabled on Windows, due to the lack of UNIX
domain socket support.
.PP
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.
.PP
If the remote SSH daemon is Gerrit Code Review, version 2.0.10 or later is
required to fix a server side protocol bug.
