64-bit Compatibility: The first four characters of a String material property would be cut off. A String's length is defined in structs.py as a c_size_t variable, which is 8 bytes wide on 64-bit Python. However, when an aiString is used as an aiMaterial property in C/C++, the length is truncated down to a 4-byte value on 64-bit machines (see MaterialSystem.cpp aiMaterial::AddProperty() for details). A new struct was declared in structs.py (MaterialPropertyString) and used in core._get_properties(). Python 3.3 Compatibility: The built-in function hasattr() changed in Python 3.2 to not trap exceptions, which means a NULL pointer ValueException now escaped when checking if a pointer was valid (hasattr(obj, 'contents') in core.call_init()) (see http://bugs.python.org/issue9666 for details). A new helper function was defined that preserves the legacy functionality of trapping the exceptions (helper.hasattr_silent()) and used throughout the code as a replacement for hasattr(). String objects would import as "bytes" rather than as a string. This was most noticeable in the key names for material properties, where the trailing ' of a bytes object would remain after it was converted to a string. The solution was to call decode() on the bytes object using utf-8 decoding. This applies to various parts of core.py. Closes #35 |
