setdiscovery: return anyincoming=False when remote's only head is nullid
This fixes (
issue2907) a crash when using 'hg incoming --bundle' with an empty
remote repo and a non-empty local repo.
This also fixes an unreported bug that 'hg summary --remote' erroneously
reports incoming changes when the remote repo is empty and the local is not.
Also, add a test to make sure
issue2907 stays fixed
$ "$TESTDIR/hghave" inotify || exit 80
$ hg init
$ touch a b
$ hg add a b
$ rm b
status without inotify
$ hg st
A a
! b
$ echo "[extensions]" >> $HGRCPATH
$ echo "inotify=" >> $HGRCPATH
inserve
$ hg inserve -d --pid-file=hg.pid 2>&1
$ cat hg.pid >> "$DAEMON_PIDS"
status
$ hg st
A a
! b
? hg.pid
$ sleep 1
Are we able to kill the service? if not, the service died on some error
$ kill `cat hg.pid`
