[Bug 379573] Re: sudo update-alternatives does not configure the default python-wxgtk in Jaunty

[stani]

** Summary changed:

- not possible to switch between python-wxgtk2.6 or python-wxgtk2.8 as the default wxPython in Jaunty
+ sudo update-alternatives does not configure the default python-wxgtk in Jaunty

** Description changed:

  In Jaunty, when both python-wxgtk2.6 and python-wxgtk2.8 are installed, this happens by default:
  >>> import wx
  >>> wx.VERSION
  (2, 6, 3, 2, '')
  
  In Intrepid, this happens by default:
  >>> import wx
  >>> wx.VERSION
  (2, 8, 8, 0, '')
  
- The behaviour in Jaunty looks like a bug to me.
+ This switch might be unexpected by programs which run fine under
+ intrepid and depend on 2.8. (In the ideal scenario they should choose
+ the right version with wxversion.)
  
  Moreover in Jaunty 2.8 seems to be configured as the default:
  $ ls /etc/alternatives | grep wx
  wx2.5.pth
  wx2.6.pth
  $ sudo update-alternatives --config wx2.6.pth 
  [sudo] password for stani: 
  
  Er zijn 2 alternatieven die 'wx2.6.pth' voorzien.
  
    Selectie    Alternatieven
  -----------------------------------------------
  *+        1    /usr/lib/wx/python/wx2.8.pth
            2    /usr/lib/wx/python/wx2.6.pth
  
  So with "update-alternatives" I can't select that "import wx", imports
  wxPython 2.8
+ 
+ In Debian this looks right:
+ $ sudo update-alternatives --config wx.pth 
+ There are 2 choices for the alternative wx.pth (providing /usr/lib/wx/python/wx.pth).
+ 
+   Selection    Path                          Priority   Status
+ ------------------------------------------------------------
+ * 0            /usr/lib/wx/python/wx2.6.pth   26        auto mode
+   1            /usr/lib/wx/python/wx2.6.pth   26        manual mode
+   2            /usr/lib/wx/python/wx2.8.pth   25        manual mode
+ 
+ When 2 is selected, wx 2.8 will be the default version (in Debian):
+ >>> import sys, wx
+ >>> print wx.VERSION
+ (2, 8, 7, 1, '')
+ >>> print sys.path
+ ['', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', '/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/PIL', '/usr/lib/python2.5/site-packages/gst-0.10', '/usr/lib/pymodules/python2.5', '/usr/lib/pymodules/python2.5/gtk-2.0', '/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode']
  
  In Jaunty if I look to wx.pth:
  $ cat /usr/lib/python2.6/dist-packages/wx.pth
  wx-2.8-gtk2-unicode
  
  In Jaunty many wx*.pth are added in comparison to Intrepid (but this is probably irrelevant):
  $ locate .pth | grep wx
  /etc/alternatives/wx2.5.pth
  /etc/alternatives/wx2.6.pth
  /usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode.pth
  /usr/lib/python2.5/site-packages/wx.pth
  /usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode/wx.pth
  /usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode.pth
  /usr/lib/python2.6/dist-packages/wx.pth
  /usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode/wx.pth
  /usr/lib/wx/python/wx2.8.pth
  /usr/share/pyshared/wx-2.8-gtk2-unicode.pth
  /usr/share/pyshared/wx-2.8-gtk2-unicode/wx.pth
  /var/lib/dpkg/alternatives/wx2.5.pth
  /var/lib/dpkg/alternatives/wx2.6.pth
  
  In Intrepid this gives:
  $ locate .pth | grep wx
  /etc/alternatives/wx2.4.pth
  /etc/alternatives/wx2.5.pth
  /usr/lib/python2.4/site-packages/wx.pth
  /usr/lib/python2.5/site-packages/wx.pth
  /usr/lib/wx/python/wx2.6.pth
  /usr/lib/wx/python/wx2.8.pth
  /var/lib/dpkg/alternatives/wx2.4.pth
  /var/lib/dpkg/alternatives/wx2.5.pth
  
  In Jaunty:
  >>> import sys
  >>> sys.path
  ['', '/usr/lib/python2.6', '/usr/lib/python2.6/plat-linux2', '/usr/lib/python2.6/lib-tk', '/usr/lib/python2.6/lib-old', '/usr/lib/python2.6/lib-dynload', '/usr/lib/python2.6/dist-packages', '/usr/lib/python2.6/dist-packages/Numeric', '/usr/lib/python2.6/dist-packages/PIL', '/usr/lib/python2.6/dist-packages/gst-0.10', '/var/lib/python-support/python2.6', '/usr/lib/python2.6/dist-packages/gtk-2.0', '/var/lib/python-support/python2.6/gtk-2.0', '/usr/lib/python2.6/dist-packages/wx-2.6-gtk2-unicode', '/usr/lib/python2.6/dist-packages/wx-2.8-gtk2-unicode']
  
  In Intrepid:
  >>> import sys
  >>> sys.path
  ['', '/usr/lib/python2.5', '/usr/lib/python2.5/plat-linux2', '/usr/lib/python2.5/lib-tk', '/usr/lib/python2.5/lib-dynload', '/usr/local/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages', '/usr/lib/python2.5/site-packages/Numeric', '/usr/lib/python2.5/site-packages/PIL', '/usr/lib/python2.5/site-packages/gst-0.10', '/var/lib/python-support/python2.5', '/var/lib/python-support/python2.5/gtk-2.0', '/usr/lib/python2.5/site-packages/wx-2.8-gtk2-unicode']
  
  So in Jaunty both wx-2.6 and wx2.8 are added to the sys.path, while in Intrepid only wx-2.8 was present. 
  To me it seems like a bug that both wx 2.6 and 2.8 are in sys.path
  
  See also this discussion on the wxpython users mailing list upstream:
  http://thread.gmane.org/gmane.comp.python.wxpython/70340
  
  Some wxpython programs are now showing bugs as they are not compatible
  anymore with wxpython2.6
  
- If possible, I would like to see this fixed that in Jaunty (like in
- intrepid) wxPython 2.8 is the default if both 2.6 and 2.8 are installed
- or that at least the user can configure it in a way.
+ If possible, it would be nice that in Jaunty (like in intrepid) wxPython
+ 2.8 is the default if both 2.6 and 2.8 are installed. For sure sudo
+ update-alternatives should work for wxpython, so that at least the user
+ can configure it the default wxpython version.
