I added that line and replaced "cdef void sync():" by
"cpdef void sync():" to be able to test it:
$ cat glarea.pyx
cimport gldraw
from gldraw cimport vec4
cdef struct Data:
gldraw.mat4 matrix
cdef Data data
cpdef void sync():
data.changed = True # <- this wrong line produces the error
It compiles without errors, but i get a exception at runtime (not
surprised):
$ python3
Python 3.4.3+ (default, Oct 14 2015, 16:03:50)
[GCC 5.2.1 20151010] on linux
Type "help", "copyright", "credits" or "license" for more information.
>>> import glarea
>>> glarea.sync()
Exception ignored in: 'glarea.sync'
AttributeError: 'dict' object has no attribute 'changed'
>>>
This would be ok for me, but i wonder if cython should recognize this at
compile time. The code tries to assign a new attribute to a cdef struct
and that will always fail, or am I wrong?
