copy & rename can ignore removed source files As mercurial now distinguishes deleted files from removed files, we can skip removed source files while copying or renaming.

#!/bin/sh

hg init
mkfifo p

hg serve --stdio < p &
P=$!
(echo lock; echo addchangegroup; sleep 5) > p &
Q=$!
sleep 1
kill -HUP $P
sleep 1
ls .hg
