We're slowly moving to the place where modules are usable on python3 as
well as python2. This is not likely to be reliably usable by 2.2 but you'll
start to see a few modules that you can use on py3 when we release.
As a first step we're starting to get modules to syntax compile with
python3 as well as python2. There's a blacklist in the testing so we
should only be attempting to compile modules which were compiLing in the
past (so we don't regress).
For exceptions, there's two possibilities for porting the code:
* if the module can't run on python2.4 (because one of its library
dependencies requires python2.6 and above) then go ahead and switch to
catching the exception via "except ClientError as e:" The module should
already document that it requires python2.6 sand above in its requirements
action.
* otherwise the module will need to use some helper code to retrieve the
exception in a way compatible with python2.4 and python3:
from ansible.module_utils.pycompat24 import get_exception
[...]
try:
raise ClientError(msg)
except ClientError:
e = get_exception()
