[libvirt] [PATCH 12/13] virsh: Introduce connection handler

Before any virsh command can be executed, client connection to daemon needs to be checked, i.e. first we try to reconnect if needed and then check the connection usability which is connection type specific. This handler is registered as client hook. --- tools/virsh.c | 8 ++++++++ 1 file changed, 8 insertions(+) diff --git a/tools/virsh.c b/tools/virsh.c index 017a669..fcbd553 100644 --- a/tools/virsh.c +++ b/tools/virsh.c @@ -915,9 +915,17 @@ virshConnectionUsability(vshControl *ctl, virConnectPtr conn) return true; } +static void * +virshConnectionHandler(vshControl *ctl) { + virshControlPtr priv = ctl->privData; + if (!priv->conn || disconnected) + virshReconnect(ctl); + if (virshConnectionUsability(ctl, priv->conn)) + return priv->conn; + return NULL; } /* --------------- -- 1.9.3
