Hi all,

I'm developing a script to keep listening if the database updated.
I found that xbmc.Monitor has a method onDatabaseUpdated

Here is my code:

import xbmc
import xbmcgui
import os

class MyMonitor(xbmc.Monitor):
def __init__( self, *args, **kwargs ):
xbmc.Monitor.__init__( self )

def onDatabaseUpdated( self ):
xbmc.log( "Database Updated!" )

monitor = MyMonitor()

And here is the xbmc logs error:

02:57:07 T:6108 ERROR: EXCEPTION: access_voilation
02:57:07 T:6108 ERROR: EXCEPTION Thrown (PythonToCppException) : -->Python callback/script returned the following error<--
- NOTE: IGNORING THIS CAN LEAD TO MEMORY LEAKS!
Error Type: <type 'exceptions.RuntimeError'>

File "C:\Users\Sultan\AppData\Roaming\XBMC\scripts\yazeeddbupdated.py", line 48, in <module>
monitor = MyMonitor()
RuntimeError: access_voilation
-->End of Python script error report<--

Any help please?

Try:

Code:

import xbmc
import xbmcgui
import os

class MyMonitor(xbmc.Monitor):

    def onDatabaseUpdated( self ):
        xbmc.log( "Database Updated!" )

monitor = MyMonitor()

I tried it. the same error

Here is the log:

First of all make sure that when indenting the code, you use either spaces or tabs. Don't mix them because that can lead to funny errors. I use 4 spaces myself.

Change

Code:

def onDatabaseUpdated( self ):

to

Code:

def onDatabaseUpdated( self, database ):

If that does not work try the following addon (this works for me).

Create a service.dbupdate directory in your addon directory and add the following files:

addon.xml:

Code:

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<addon id="service.dbupdate"
       name="DBUpdate"
       version="0.1.0"
       provider-name="yourname">
  <requires>
    <import addon="xbmc.python" version="2.14.0"/>
  </requires>
  <extension point="xbmc.service" library="service.py" start="startup"/>
  <extension point="xbmc.addon.metadata">
    <platform>all</platform>
    <summary lang="en">Log when the database is updated.</summary>
    <description>Log when the database is updated.</description>
    <license>GPL 2.0</license>
  </extension>
</addon>

service.py:

Code:

import os
import xbmc

class MyMonitor(xbmc.Monitor):

    def onDatabaseUpdated(self, database):
        xbmc.log("service.dbupdate: onDatabaseUpdated()")


if (__name__ == "__main__"):

    xbmc.log("service.dbupdate: Starting: DBUpdate v0.1.0")

    monitor = MyMonitor()

    while (not xbmc.abortRequested):
        xbmc.sleep(1000)

    del monitor

    xbmc.log("service.dbupdate: Stopped: DBUpdate v0.1.0")

After starting XBMC and updating the library:

~/.xbmc/temp$ tail -F xbmc.log |grep service.dbupdate
tail: ‘xbmc.log’ has been replaced; following end of new file
18:06:57 T:140218510325504 NOTICE: service.dbupdate: Starting: DBUpdate v0.1.0

It worked leechguy :-)
Thank you so much,

I think the problem is that I was trying to access xbmc.Monitor via scripts. I didn't defined my script as addon.

Thank you again guys for the awesome help.

Cool Good luck with your add-on!

Hi,
I've tried the service.dbupdate example as i have a problem with xbmc.Monitor in Jarvis (Debian (16.1 Debian package version: 16.1+dfsg1-2). Platform: Linux x86 64-bit)

When you enable/disable the service the whole kodi interface get stuck.

Any idea of an other way to kill the xbmc.Monitor thread ?

pci.

Finally i found it.
I've got another service that "attach" an xbmcaddon.Addon() object in the xbmc.Monitor child class.
If think it create a lock.

I think when i tried to enable/disable the service.dbupdate my kodi instance was in bad condition due to the other service doing weird things.

An example of thing to avoid:
class AnotherMonitor(xbmc.Monitor):
def __init__(self):
self.myaddon=xbmcaddon.Addon() <-- This is a really bad idea

the xbmc.abortRequested method in info above is outdated, stay away from it :-)
