0.11.2 wiki error: NameError: global name 'set' is not defined

[pmoura@…]

Hi!

I've just update a 0.11.1 installation (​http://trac.logtalk.org) to 0.11.2. No problems with the update. However, accessing most of the wiki pages linked from the home page gives the error:

`NameError: global name 'set' is not defined`

In the log file I found the following entry:

    self._sanitizer = TracHTMLSanitizer()
  File "/home/.purrmethius/pmoura/trac/lib/python2.3/site-packages/Trac-0.11.2-py2.3.egg/trac/util/html.py", line 29, in __init__
    safe_attrs = HTMLSanitizer.SAFE_ATTRS | set(['style'])
NameError: global name 'set' is not defined

Thanks for developing great software. Best regards,

Paulo

Searching the web for the error message, it seems the problem is related to the use of Python 2.3. Adding the following line to the trac/util/html.py file (around line 20) seems to solve the problem:

from sets import Set as set

Wow, that was quick... It is a bit unfortunate that this has crept in right before the release. I hope that there are not too many Trac users who still run on Python 2.3.

Anyway, it's fixed in 0.11-stable in [7667]. Thanks for the bug report. Did you have any other problems with 0.11.2 related to Python 2.3? Ideally, we should have a 2.3 build host for 0.11-stable, but I think this will be difficult.

What's the policy for such a "blocker" issue (for 2.3)? Should we tell people to install from SVN, or do we re-tag and update the release tarballs?

So far I've not detected any other problems in using Trac 0.11.2 with Python 2.3 but I only performed limited testing.

This fix has been released as 0.11.2.1.
