[Cython] problematic code in C++ pyregr tests
Hi,
I noticed a couple of problems in the latest pyregr test run for py3k.
https://sage.math.washington.edu:8091/hudson/job/cython-devel-tests-pyregr-py3k-cpp/951/consoleFull
1) test_contextlib.cpp:16926: warning: deprecated conversion from string
constant to ‘char*’
This repeated warning refers (I assume) to each literal in this code:
char* __pyx_import_star_type_names[] = {
__pyx_scope_struct_2_test_contextmanager_finally,
__pyx_scope_struct_19_test_contextmanager_as_decorator,
[...]
__pyx_scope_struct_6_test_contextmanager_except,
__pyx_scope_struct_12_testWithCondition,
0
};
This looks like a standard C++ WTF to me. I noticed that Lisandro keeps
casting string literals in his code, so I wonder if that's something we
need to do here as well?
2) test_cgi.cpp:2494: error: ‘None’ was not declared in this scope
There seems to be a problem with the dict-loop optimisation. This is how
the following code gets translated:
* for k, v in dict(form).items(): #
__Pyx_INCREF(None);
__Pyx_XDECREF(__pyx_t_1);
__pyx_t_1 = None;
__pyx_t_5 = 0;
__pyx_t_6 = PyDict_Size(__pyx_t_1);
while (1) {
/* __pyx_t_7 allocated */
/* __pyx_t_8 allocated */
if (unlikely(__pyx_t_6 != PyDict_Size(__pyx_t_1))) {
PyErr_SetString(PyExc_RuntimeError, dictionary changed size during
iteration); {__pyx_filename = __pyx_f[0]; __pyx_lineno = 114;
Looks like the literal doesn't get evaluated. I'll look into this.
3) warning: TestClassUtilityCode:18:10: 'cpdef_method' redeclared
warning: TestClassUtilityCode:29:10: 'cpdef_cname_method' redeclared
4) test_pep263.cpp:520: error: redefinition of ‘PyObject* __pyx_kp_b_1’
test_pep263.cpp:519: error: ‘PyObject* __pyx_kp_b_1’ previously declared here
test_pep263.cpp:526: error: redefinition of ‘PyObject* __pyx_kp_b_2’
test_pep263.cpp:525: error: ‘PyObject* __pyx_kp_b_2’ previously declared here
Triggered by this code, which refers to the same byte string literals twice
in both cases:
* self.assertEqual( #
* .encode(utf-8),
* b'\xd0\x9f\xd0\xb8\xd1\x82\xd0\xbe\xd0\xbd'
*/
/* __pyx_t_1 allocated */
__pyx_t_1 = PyObject_GetAttr(__pyx_v_self, __pyx_n_s__assertEqual); if
(unlikely(!__pyx_t_1)) {__pyx_filename = __pyx_f[0]; __pyx_lineno = 9;
__pyx_clineno = __LINE__; goto __pyx_L1_error;}
__Pyx_GOTREF(__pyx_t_1);
/* __pyx_t_2 allocated */
__pyx_t_2 = PyTuple_New(2); if (unlikely(!__pyx_t_2)) {__pyx_filename =
__pyx_f[0]; __pyx_lineno = 9; __pyx_clineno = __LINE__; goto __pyx_L1_error;}
__Pyx_GOTREF(((PyObject *)__pyx_t_2));
__Pyx_INCREF(((PyObject *)__pyx_kp_b_1));
PyTuple_SET_ITEM(__pyx_t_2, 0, ((PyObject *)__pyx_kp_b_1));
__Pyx_GIVEREF(((PyObject *)__pyx_kp_b_1));
__Pyx_INCREF(((PyObject *)__pyx_kp_b_1));
PyTuple_SET_ITEM(__pyx_t_2, 1, ((PyObject *)__pyx_kp_b_1));
__Pyx_GIVEREF(((PyObject *)__pyx_kp_b_1));
* self.assertEqual( #
* \.encode(utf-8),
* b'\\\xd0\x9f'
*/
/* __pyx_t_3 allocated */
__pyx_t_3 = PyObject_GetAttr(__pyx_v_self, __pyx_n_s__assertEqual); if
(unlikely(!__pyx_t_3)) {__pyx_filename = __pyx_f[0]; __pyx_lineno = 13;
__pyx_clineno = __LINE__; goto __pyx_L1_error;}
__Pyx_GOTREF(__pyx_t_3);
/* __pyx_t_2 allocated */
__pyx_t_2 = PyTuple_New(2); if (unlikely(!__pyx_t_2)) {__pyx_filename =
__pyx_f[0]; __pyx_lineno = 13; __pyx_clineno = __LINE__; goto __pyx_L1_error;}
__Pyx_GOTREF(((PyObject *)__pyx_t_2));
__Pyx_INCREF(((PyObject *)__pyx_kp_b_2));
PyTuple_SET_ITEM(__pyx_t_2, 0, ((PyObject *)__pyx_kp_b_2));
__Pyx_GIVEREF(((PyObject *)__pyx_kp_b_2));
__Pyx_INCREF(((PyObject *)__pyx_kp_b_2));
PyTuple_SET_ITEM(__pyx_t_2, 1, ((PyObject *)__pyx_kp_b_2));
__Pyx_GIVEREF(((PyObject *)__pyx_kp_b_2));
5) there are also several compiler crashes in that log
6) several tests bail out with
File runtests.py, line 900, in run_test
except (unittest.SkipTest, support.ResourceDenied):
AttributeError: 'module' object has no attribute 'ResourceDenied'
I guess that's an incompatibility of our test runner with the latest Py3k.
7) g++: /.../workspace/BUILD/pyregr/cpp/test_inspect.o: No such file or
directory
g++: no input files
There are loads of these - not sure what might trigger them.
As I said, I'll look into the dict looping bug. If any of the other bugs is
obvious to someone and not too hard to fix, it would be nice to get it done
for the release. However, I think none of them is a real blocker.

[Cython] Entry.is_arg question
What is the meaning of Entry.is_arg flag? For generic python arguments it's set to 0, it makes it very tricky to determinate whether entry is argument: https://github.com/cython/cython/blob/master/Cython/Compiler/FlowControl.py#L515 Can we have is_args flag set for all kind of args?

Re: [Cython] OpenMP problem
That sounds risky; I think we should consider master as non-rebaseable except in emergencies. So fixes should be pushed to release and then merged into master. Of course, for something like this with no development depending on it one can just delay the merge for a day or two in case more fixes show up. -- Sent from my Android phone with K-9 Mail.
