Subject: Make the "exit" unixctl command reliable in ovsdb-server, ovs-vswitchd.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6d37aaf186c9f4595258903241f4fa0175ecf6dd;p=openvswitch

Make the "exit" unixctl command reliable in ovsdb-server, ovs-vswitchd.

If "ovs-appctl exit" happens to hit ovsdb-server or ovs-vswitchd at a
moment when nothing else is happening to wake the daemon up, it can take a
long time for them to exit.

This seems to account for occasional "make check" failures on Nicira's
internal builds.  It probably fixes some Debian automatic build failures
as well.
