crazy reload hack (779 bytes, patch)

Description Alexander Larsson 2006-07-28 02:06:57 UTC 
importing gtk again if the first import fails (say if DISPLAY is wrong) breaks with:
Traceback (most recent call last):

+ Trace 69720

  • File "/usr/share/system-config-display/xconf.py", line 364 in ? 
    reload(gtk)
  • File "/usr/lib64/python2.4/site-packages/gtk-2.0/gtk/__init__.py", line 40 in ? 
    from gtk import _gtk
ImportError: cannot import name _gtk 

This also happens with:
import gtk
reload(gtk)

While this looks unusual its used in fedora-config-display to first try to connect to the existing display, and if that fails start a new X server to connect to.

The reason this happens is that the above mentioned file deletes gtk._gtk to avoid users accessing it. 

J5 and I came up with a hack that fixes this. Basically you resurrect the gtk._gtk from the sys.modules hashtable the second time.

I checked in a different (simplified) version of the patch that makes it possible to reload the gtk module:
