Hello all,
I used the Twisted 8.2.0 for OS X 10.5 installer from [1] to install
twisted on my mac. I don't understand why, but I seem to have two
copies of the source on the disk, one at
/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/twisted
and another at /Library/Python/2.5/site-packages/twisted. Both
locations are on sys.path, the former taking precedence.
More curiously, the two versions appear to be different. The following
snippet fails with the version that python finds by default:
from twisted.python import usage
class Options(usage.Options):
optParameters = [["shiny_integer", "s", 1, None, int]]
optParameters = [["dummy_float", "d", 3.14159, None, float]]
o = Options()
Resulting in:
Traceback (most recent call last):
File "options.py", line 7, in <module>
o = Options()
File
"/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/twisted/python/usage.py",
line 120, in __init__
(longOpt, shortOpt, docs, settings, synonyms, dispatch) = c()
File
"/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/twisted/python/usage.py",
line 287, in _gather_parameters
long, short, default, doc = util.padTo(4, parameter)
File
"/System/Library/Frameworks/Python.framework/Versions/2.5/Extras/lib/python/twisted/python/util.py",
line 227, in padTo
raise ValueError, "%d elements is more than %d." % (len(seq), n)
ValueError: 5 elements is more than 4.
The same snippet works with the version in the other location. Is this a bug?
Thanks,
Matt.
