What is the python equivalent of g_log_set_handler when using GLib from python

Question

I want to set the log level in my python glib project. Therefore I am looking for the g_log_set_handler() equivalent when using GLib from python via gi.repository.

But the expected GLib.log_set_handler function seems to be missing. Here is a sample output of my python shell:

~$ python
Python 2.7.3 (default, Apr 10 2013, 06:20:15) 
[GCC 4.6.3] on linux2
Type "help", "copyright", "credits" or "license" for more information.
>>> from gi.repository import GLib 
>>> GLib.log_set_fatal_mask
<function log_set_fatal_mask at 0x2a7b668> 
>>> GLib.log_set_handler
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/lib/python2.7/dist-packages/gi/module.py", line 316, in __getattr__
    attr = super(DynamicGLibModule, self).__getattr__(name)
  File "/usr/lib/python2.7/dist-packages/gi/module.py", line 243, in __getattr__
     return getattr(self._introspection_module, name)
  File "/usr/lib/python2.7/dist-packages/gi/module.py", line 105, in __getattr__
    self.__name__, name))
  AttributeError: 'gi.repository.GLib' object has no attribute 'log_set_handler'
>>> 

As one can see, GLib from the introspection repository is found and the log_set_fatal_mask function exists (which is the equivalent of the g_log_set_fatal_mask). But log_set_handler is not found.

Why is that and how could I correctly set my loglevel from within python?

Answer 1

I found out this is currently not possible and a known bug within either gobject-introspection or glib, since g_log_set_handler is not bindable.
