MathCaptchaPlugin crashes Trac 1.2

[Florian Berger <florian.berger@…>]

MathCaptchaPlugin looks like a really neat and useful plugin: it sets up a spam barrier, has no external dependencies like TracCaptchaPlugin, and is much more slim than ​SpamFilter.

Sadly, after installing and enabling it crashes my trac 1.2:

Traceback (most recent call last):
  File "/usr/lib/python2.7/site-packages/trac/web/api.py", line 710, in send_error
    data, 'text/html')
  File "/usr/lib/python2.7/site-packages/trac/web/chrome.py", line 1123, in render_template
    stream |= self._filter_stream(req, method, filename, stream, data)
  File "/usr/lib/python2.7/site-packages/genshi/core.py", line 133, in __or__
    return Stream(_ensure(function(self)), serializer=self.serializer)
  File "/usr/lib/python2.7/site-packages/trac/web/chrome.py", line 1436, in inner
    data)
  File ".../plugins/MathCaptcha.py", line 373, in filter_stream
    if self.is_banned(req):
  File ".../plugins/MathCaptcha.py", line 244, in is_banned
    db = self.env.get_db_cnx()
AttributeError: 'Environment' object has no attribute 'get_db_cnx'

Any chance of getting MathCaptche ported to 1.2?

In 16418:

5.0dev: Branch for Trac 1.2 and conform to PEP8

Refs #13131.

That was probably not supposed to fixed it yet. I checked it out anyway, and the problem AttributeError: 'Environment' object has no attribute 'get_db_cnx' still persists.

In 16419:

5.0dev: Adapt to Trac 1.2 database API

Fixes #13131.

Works like a charm. Thanks!
