runtests throws an exception because of clash between gettext and doctest

[David D Lowe]

I have language support for French and Russian installed through Ubuntu's "Language Support" tool. I'm running from source, trunk revno 829. Running the following command from the root of the branch gives me the following output:

$ python -m wxbanker/runtests

TypeError: 'bool' object is not callable

I suspect this is because of the well-known clash between doctest and gettext.

I edited line 334 in wxbanker/currencies.py to become:

CurrencySttrings[0] += " (%s)" % "detected"

I received the attached output.

[Michael Rooney (mrooney)]

Hm, I'm getting "TypeError: 'bool' object is not callable" as well (but not the doctests error, what is your system locale? The tests assume en_US I believe), but I swore it was working just the other night, how odd.

Anyway, the doctests are really legacy tests, in the mean time you should be able to just run the unit tests: python wxbanker/tests/alltests.py

[David D Lowe (flimm)]

I don't get the doctest errors when I set the environment variable LANG to en_US.utf8.

[Michael Rooney (mrooney)]

I can't reproduce this any more on a fresh checkout, can you (with en_US locale)?

[David D Lowe (flimm)]

I can still reproduce this with trunk revno:829. (Is that what you mean by a fresh checkout?)

[Michael Rooney (mrooney)]

I see, it seems to be happening in Maverick but not Lucid, how odd. Are you running Maverick? I wonder if it is a Python 2.6.6 change, or something else.

[David D Lowe (flimm)]

Yes, I'm running Maverick.

[Michael Rooney (mrooney)]

Okay, I'm not sure why that was happening since I was overriding the display hook which works fine in Lucid, but that's fine. I looked over the doctests and I am pretty sure the unit tests cover everything they do and more, in a better way (I can't remember the last time the doctests found a regression), so I just deleted them as well as runtests.py and testhelpers.py which aren't needed anymore. So now it will work as before: python wxbanker/tests/alltests.py

I'll also add a check that the tests are running under en_US.utf8 and attempt to set that first, to avoid the other failures.

Thanks for finding this and prompting me to do some cleanup!
