ctypes: delay conversion from c_char_p to string
I have a function exposed through ctypes that returns a c_char_p. Since I need to deallocate that c_char_p, it's inconvenient that ctypes copies the c_char_p into a string instead of giving me the raw pointer. I believe this will cause a memory leak, unless ctypes is smart enough to free the string itself after the... 24 Apr 2010 09:24

ctypes errcheck question
According to the ctypes docs: http://docs.python.org/library/ctypes.html An errcheck function should return the args tuple when used with out parameters (section 15.15.2.4. Function prototypes).

Declarative programming for the Model part of an application
Dear all, Last week, I raised the question "Could declarative programming be useful for the Model part of an application ?", and I suggested an open-source project, Yoopf, to provide such a paradigm in Python. Stefan told me that the proposal lacked clarity. I have thus updated the description, and he now finds... 23 Apr 2010 20:49

Dear all, I'm trying to use the shove module (http://pypi.python.org/pypi/shove) for a simple script. The script read a CSV file ad store the data.
