global name 'GeneratorExit' is not defined

[millman@…]

With Python 2.4 and Trac 10.5 certain macros (e.g., Image) raise an exception:

  global name 'GeneratorExit' is not defined

I think GeneratorExit was introduced in Python 2.5: ​http://docs.python.org/whatsnew/pep-342.html

Removing the following lines

 449                except GeneratorExit:
 450                    # never catch GeneratorExit
 451                    raise

from /usr/lib/python2.4/site-packages/trac/wiki/macros.py resolves this issue.

This is the reason the change in 10.5 was introduced: ​http://trac.edgewall.org/ticket/5339

Adding the following to the top of the module:

   try:
       GeneratorExit
   except NameError:
       class GeneratorExit(Exception): pass

would allow the fix for 5339 to stay.

I can confirm that the fix suggested in the ticket works, after being hit by the same bug as well.

Seems indeed needed for 2.4
