rsync - Oct 2018 - Is there a way to get an rsync client to communicate over stdin/stdout?

Hello,

Is there a way to get an rsync client to communicate over stdin/stdout?

I found these two emails from 2004.  The second email mentions that
there might be a patch.

https://www.mail-archive.com/rsync at lists.samba.org/msg09392.html
https://www.mail-archive.com/rsync at lists.samba.org/msg09427.html

Is anyone aware of a way to do this?  Or of a published patch that does it?

I figured I would ask before modifying the rsync source code myself.

(Obviously, there would need to be some mechanism for the rsync client
to output the command line arguments for the rsync server.  My use
case is I have a Python script creating and managing pipes.  Python
will Popen the rsync client, and then I want the rsync client to use
the pipes [probably stdin and stdout] given to it by Python.)

Cheers,

Parke

Take a look at the lsh scripts that come with rsync.

I find two scripts: lsh (in Perl) and lsh.sh.

I don't think they do want I want.  The both look like remote shell
substitutes.  Am I wrong about this?

I want the rsync client to just use its stdin and stdout.  Any option
whereby the rsync client spawns a server via a remote shell program
will probably not work for me.

Cheers,
