MYSTERY: how can "%s"%error be different from "%s"%str(error) in Python 2.6?
APOLOGY: I tried to strip this down, but could not find a simple way to reproduce the problem. This way works, however. (There is a discussion on the docutils-develop list.) Although there are several steps, we are talking about less than 5 minutes to document the puzzle. Please use the specific revision (or earlier) in the directions, as later revisions implement a work around. 1. Check out revision 6121 from docutils http://docutils.sourceforge.net/docs/dev/repository.html 2. Install docutils under Python 2.6 3. Process the file below [1]_ using the rst2html.py script (found in Python26/Scripts on Windows platforms) 4. Note the IOError:: temp.rst:: (SEVERE/4) Problems with "include" directive path: IOError: (2, 'No such file or directory'). Exiting due to level-4 (SEVERE) system message. 5. Make the following change and *no other* changes: In docutils/parsers/rst/directives/misc.py (line 66-67) change :: raise self.severe('Problems with "%s" directive path:\n%s: %s.' % (self.name, error.__class__.__name__, error)) to :: raise self.severe('Problems with "%s" directive path:\n%s: %s.' % (self.name, error.__class__.__name__, str(error))) 6. Process the same file the same way. Note the change in the IOError:: temp.rst:: (SEVERE/4) Problems with "include" directive path: IOError: [Errno 2] No such file or directory: 'doesnotexist.rst'. Exiting due to level-4 (SEVERE) system message. 7. Try this again in Python 2.5. The correct (filename reported) error report is produced both times. So this is a Python 2.6 change. Clues? Bug or feature? I'm going to hazard a guess that there was an undocumented (in What's New) change to the __unicode__ method of BaseException. Thanks, Alan Isaac ..
