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

2022-09-01 15:41:12 +00:00

The \fB\-\-auto\-gc\fR option can be used to trigger garbage collection on all projects.

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.
