Currently working on a v19 version of my addon and I'm implementing several dialogs, background progress dialogs, and notification dialogs.

I've found in testing that if I have one function generate a notification and a follow on function generate another notification, that problems can occur.

For example:

python:


def func1():

current_dialog = xbmcgui.Dialog()

current_dialog.notification('Test1','Test1',xbmcgui.NOTIFICATION_INFO,5000,sound=False)

... do stuff...

xbmc.executebuiltin('Dialog.Close(notification,true)')

xbmc.sleep(NOTIFICATION_DEINIT_TIME) #Close the notification and wait for de-init to ensure any follow on notification are correctly shown, unsure if there's a better way to do this

del current_dialog



def func2():

current_dialog = xbmcgui.Dialog()

current_dialog.notification('Test2,'Test2',xbmcgui.NOTIFICATION_INFO,5000,sound=False)

... do stuff...

xbmc.executebuiltin('Dialog.Close(notification,true)')

xbmc.sleep(NOTIFICATION_DEINIT_TIME) #Close the notification and wait for de-init to ensure any follow on notification are correctly shown, unsure if there's a better way to do this

del current_dialog

If I call the first function and notification, then the second function and notification there can be a race condition where the first notification isn't fully closed/removed and the second notification wont appear.

Is there a way to determine if a dialog or notification is visible/open to avoid any race conditions? It doesn't appear that xbmcgui.getCurrentWindowId() works for dialog.notification.

Thanks in advance

I have a service process which does a lot of background processing with timers and events.  I use a combination of addon settings and global variables to manage race conditions.  For example, I'll set an addon setting or global variable when action 1 occurs and then when action 2 starts I check if action 1 is still active before doing anything.  if it is, action 2 exits.  Action1 resets the setting or variable when it ends.  Likewise in reverse is action 2 fires first.  Probably not the most elegant solution but it has been bulletproof for me.

Maybe xbmc.getCondVisibility('Window.IsActive(notification)') ? I've never tried it so don't know if it'll work.

That worked. Thank you!
