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.
