Error reporting for wiki processors broken

[Christopher Lenz]

Since the WikiProcessor refactoring [1347] error reporting on Wiki processors is broken, so that instead of getting the original error embedded in the page, you get a general Trac error page with the following exception:

Traceback (most recent call last):
  File "/Users/chris/Projekte/Trac/trunk/trac/web/cgi_frontend.py", line 102, in run
    dispatch_request(os.getenv('PATH_INFO', ''), req, env)
  File "/Users/chris/Projekte/Trac/trunk/trac/web/main.py", line 320, in dispatch_request
    module.run(req)
  File "/Users/chris/Projekte/Trac/trunk/trac/Module.py", line 49, in run
    self.render(req)
  File "/Users/chris/Projekte/Trac/trunk/trac/Wiki.py", line 150, in render
    self._render_view(req, pagename)
  File "/Users/chris/Projekte/Trac/trunk/trac/Wiki.py", line 316, in _render_view
    info = {
  File "/Users/chris/Projekte/Trac/trunk/trac/WikiFormatter.py", line 637, in wiki_to_html
    Formatter(hdf, env, db, absurls).format(wikitext, out)
  File "/Users/chris/Projekte/Trac/trunk/trac/WikiFormatter.py", line 594, in format
    self.handle_code_block(line)
  File "/Users/chris/Projekte/Trac/trunk/trac/WikiFormatter.py", line 569, in handle_code_block
    self.out.write(system_message('Error: Failed to load processor <code>%s</code>' % name, e))
NameError: global name 'e' is not defined

In particular, I'm getting the error on the WikiRestructuredTextLinks when docutils is not installed.

Christian, I'm assigning this to you as you know that particular change much better than I do.

[Mark Rowe <edgewall.com@…>]

Simple patch that probably fixes the problem (untested).

Oops, sorry for the error. I'll apply the patch, but, as such, the error message is quite cryptic. I'll see if I can find a better solution later.

[Christian Boos]

Fixed in [1402]

[Christopher Lenz <cmlenz@…>]

cboos, [1402] seems to have broken a couple of the wiki unit tests.
