| helpDescription = """ |
| The '%prog' 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, '%prog' |
| will update the remote branches and rebase any new local changes |
| on top of the new remote changes. |
| |
| '%prog' 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, '%prog' 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. |
| |
| 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 '%prog' 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 |
| %prog |
| |
| 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. '%prog' 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. |
