tests: create "private" repository in already-updated state
I'm going to add more copies of the repo and it's easier to work with
the repo if it's already been updated.
. $TESTDIR/testlib/common.sh
cat >> $HGRCPATH <<EOF
[ui]
interactive = true
[phases]
publish=False
[extensions]
evolve =
[experimental]
evolution.effect-flags = yes
EOF
sync() {
hg pull -R $TESTTMP/server . -q
}
