@ -53,6 +53,35 @@ 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.
