I was in a plumbing supply house a couple months ago. They had a gadget at
the counter they were showing someone. A threaded shaft rig with a rubber
that expands. You could put it into the pipe, adn then slip a full flow
(ball or gate) valve over it, and then solder while the expander holds water
back.

It was about twenty bucks, don't know if it works or not.

shut off completely? Use compression fittings?

No, I wouldn't trust compression fittings at all here.
One time-worn trick is to stuff the pipe with bread (!).
It soaks up the trickle while you solder and flushes out later.
A hotter torch (MAP or even oxy-acetylene) works wonders too.
