Trying to compile django I've found some problems:
1. It seems that cython currently doesn't support tuples inside args definition:
def foo((a, b), c):
Currently this gives missing argument name and crash inside
CreateControlFlow graph
cython -X binding=True django/contrib/gis/forms/fields.py -o
django/contrib/gis/forms/fields.c
It may be valid Py2-only syntax, but I consider its usage a bug in Django.
2. Concatenating unicode and str isn't supported:
I guess that this is mostly django problem
Error compiling Cython file:
------------------------------------------------------------
...
default_error_messages = {
'no_geom' : _(u'No geometry value provided.'),
'invalid_geom' : _(u'Invalid geometry value.'),
'invalid_geom_type' : _(u'Invalid geometry type.'),
'transform_error' : _(u'An error occurred when transforming
the geometry '
'to the SRID of the geometry form field.'),
^
------------------------------------------------------------
django/contrib/gis/forms/fields.py:21:30: Cannot mix string literals
of different types, expected u'', got ''
That's a bug in Django. Worth submitting a patch to their bug tracker. It
works in this case, but it's not what they want in their code:
>>> u'abc\u1234'
u'abc\u1234'
>>> u'abc' '\u1234'
u'abc\\u1234'
3.Reraise not inside except clause, here is simple example
def foo():
print 'catched'
raise
try:
raise IndexError
except IndexError:
foo()
It would be possible to support this, given that we are compatible with
CPython regarding the place where exceptions are stored while being
handled. Despite of what I initially thought, this is a feature of both Py2
and Py3, even though I expect it to be rarely used and somewhat error prone.
