Rework of runtime non-real-time threading, and shared object dynamic loading :
- All exposed operations on PLCObject are now serialized through main thread
(@RunInMain). Only one exception : python trace thread calling _GetDebugData
- Re-loading of same shared object is prevented. dlclose/delte/rewrite/dlopen
don't happen in that case. This is a workaround for some xenomai copperplate
bug triggering segfault, inbetween delete and rewrite.
- Trace thread now waits for data, dies if no data, and dies instead of
suspending as before when no data consumed after 3 seconds.
- Disabled threading in Pyro client
- Enforced auxiliary threads starting sequence : Pyro -> [UI] ->
PLCWorker.RunLoop
// import Nevow.Athena
function init() {
Nevow.Athena.Widget.fromAthenaID(1).callRemote('HMIexec', 'HMIinitialisation');
}
WebInterface.PLC = Nevow.Athena.Widget.subclass('WebInterface.PLC');
WebInterface.PLC.method(
'updateHMI',
function (self, data) {
d = self.callRemote('getPLCElement');
d.addCallback(
function liveElementReceived(le) {
d2 = self.addChildWidgetFromWidgetInfo(le);
d2.addCallback(
function childAdded(widget) {
var node = self.nodeById('content');
node.replaceChild(widget.node, node.getElementsByTagName('div')[0]);
init();
});
});
});
Divmod.Base.addLoadEvent(init);
