TypeError when playing with examples

[Jan Hutař]

Hello,
I have tried examples from UsageExamples and am getting this error:



Python 2.5.1 (r251:54863, Oct 30 2007, 13:45:26)

>>> cfgpr.get('ui', 'width')
'150'
>>> cfgpr.set('ui', 'width', 175)
>>> cfgpr.get('ui', 'width')

TypeError: argument of type 'int' is not iterable



I have created 2 patches which fixes this, but both causes at least 1
unit test to fail:

* with int-not-iterable-get.patch these unit-tests fails:

tests.test_compat.ConfigParserTestCase

* with int-not-iterable-set.patch these unit-tests fails:

tests.test_compat.RawConfigParserTestCase
tests.test_compat.ConfigParserTestCase

I do not have a clue which of them is better. Please could you review
them and provide some feedback on this issue?

Hi Jan,

Thanks for pointing this out. This looks like a bug at first glance.
I'll take a look at your patches in the next couple of days and post a
message here when I know more.

OK, I looked into this, and unfortunately, this is expected behavior.
Python's ConfigParser class behaves the same way, and the Python test
suite has tests to check for this. See the test
ConfigParserTestCase.test_set_nonstring_types in
test/test_cfgparser.py in the standard library.

As a workaround, you can pass "raw=True" to get() to turn off the
interpolation, which will eliminate the error.

I'll fix the usage examples to not use an int.

I see, thank you for investigating this.
